    [001] The specification is related to a heating set suitable for use in an aerosol generating system. In particular, the invention relates to a heating set suitable for insertion into an aerosol-forming substrate of a smoking article in order to internally heat the aerosol-forming substrate.
    [002] There is an increasing demand for portable aerosol generating devices capable of providing aerosol for user inhalation. A specific area of demand is that of heated smoking devices, in which an aerosol-forming substrate is heated in order to release volatile flavor compounds, without combustion of the aerosol-forming substrate. The volatile compounds released are carried inside an aerosol for the user.
    [003] Any aerosol generating device that operates by heating an aerosol-forming substrate must include a heating assembly. Several different types of heating sets have been proposed for different types of aerosol forming substrate.
    [004] A type of heating set proposed for heated smoking devices operates by inserting a heater into a solid aerosol-forming substrate, such as a tobacco plug. This arrangement allows the substrate to be heated directly and efficiently. However, there are several technical challenges with this type of heating set, including requirements for small size, robustness, low manufacturing cost, sufficient operating temperatures and effective location of the heat generated.
    [005] It would be desirable to provide a robust and inexpensive heating set for an aerosol generating device that provides a localized source of heat in order to heat an aerosol-forming substrate.
    [006] In a first aspect of the invention, there is a heating set for heating an aerosol-forming substrate, the heating set being characterized by:
    [007] a heater formed by a heating element with electrical resistance and a heating substrate; and
    [008] a heater support coupled to the heater;
    [009] the heating element is characterized by a first part and a second part, configured in such a way that, when an electric current passes through the heating element, the first part is heated to a temperature higher than the temperature of the second part, being that the first part of the heating element is positioned in a heating area of the heating substrate, and the second part of the heating element is positioned in a supporting area of the heating substrate; and the heater support is attached to the support area of the heater substrate.
    [0010] As used herein, the term 'aerosol-forming substrate' refers to a substrate capable of releasing volatile compounds that can form an aerosol. These volatile compounds can be released by heating the aerosol-forming substrate. An aerosol-forming substrate may conveniently be part of an aerosol-generating article or a smoking article.
    [0011] As used herein, the terms 'aerosol-generating article' and 'smoking article' refer to an article containing an aerosol-forming substrate capable of releasing volatile compounds that can form an aerosol. For example, an aerosol-generating article may be a smoking article that generates an aerosol that can be inhaled directly into a user's lung through the user's mouth. An aerosol-generating article may be disposable. A smoking article composed of an aerosol-forming substrate containing tobacco is called a tobacco stick.
    [0012] The first part is heated to a temperature higher than the temperature of the second part, as a result of the electric current that passes through the heating element. In one embodiment, the first part of the heating element is configured to reach a temperature of approximately 300oC to 550oC in use. Preferably, the heating element is configured to reach a temperature of approximately 320oC to 350oC.
    [0013] The heater support provides structural support to the heater and allows it to be securely attached within an aerosol generating device. The heater support can contain a polymeric material and is favorably formed from a molded polymeric material, such as polyether-ether-ketone (PEEK). The use of a molded polymer allows the heater holder to be molded around the heater and, therefore, hold the heater firmly. It also allows the heater support to be produced with the desired external shape and dimensions in an inexpensive way. The heater substrate may have mechanical characteristics, such as protrusions or crevices, which improve the attachment of the heater support to the heater. Obviously it is possible to use other materials for the heater support, such as a ceramic material. The heater support can be favorably formed from a moldable ceramic material.
    [0014] The use of a polymer to secure the heater means that the temperature of the heater in the vicinity of the heater support needs to be controlled in order to remain below the temperature at which the polymer will melt, burn or suffer degradation of some other type. At the same time, the temperature of the heater part within the aerosol-forming substrate needs to be sufficient to produce an aerosol with the desired properties. Therefore, it is desirable to ensure that the second part of the heating element, at least at the points in contact with the heater support, remains at a temperature below the maximum allowed during use.
    [0015] In a heater with electrical resistance, the heat produced by the heater depends on the resistance of the heating element. For a certain current, the greater the resistance of the heating element, the more heat will be produced. It is desirable that most of the heat produced is produced by the first part of the heating element. Likewise, it is desirable that the first part of the heating element has a higher electrical resistance per unit length than that of the second part of the heating element.
    [0016] The heating element has the advantage of being composed of parts made of different materials. The first part of the heating element can be formed by a first material, and the second part of the heating element can be formed by a second material, in which the first material has an electrical resistance coefficient higher than that of the second material. For example, the first material can be Ni-Cr (Nickel-Chromium), platinum, tungsten or alloy wires and the second material can be gold, silver or copper. The dimensions of the first and the second part of the heating element can also be different, in order to provide a lower electrical resistance per unit length in the second part.
    [0017] The materials of the first and the second part of the heating element can be selected according to their thermal and electrical properties. The advantage of the second part of the heating element is that it has a low thermal conductivity, in order to reduce the conduction of heat from the heating area to the heater support. Therefore, the choice of material for the second part of the heating element can be a balance between a high electrical conductivity and a low thermal conductivity, at least in the region between the first part of the heating element and the heater support. In practice, it was concluded that gold is a good choice of material for the second part of the heating element. Alternatively, it is possible to use silver as the material for the second part.
    [0018] The second part of the heating element has the advantage of containing two sections, each connected separately to the first part of the heating element, in order to define an electrical flow path from a section of the second part to the first part and then on to the other section of the second part. The heater support can surround the two sections of the second part. Obviously, the second part can contain more than two parts, each of which is electrically connected to the first part.
    [0019] The heating element can contain a third part configured to establish an electrical connection with the power source, while the third part is positioned on the opposite side of the heater support with respect to the first part of the heating element. The third part can be formed from a different material from the first and the second part, and can be chosen in order to provide less electrical resistance and suitable connection properties, for example, to be easily weldable. In practice, it was concluded that silver is a good choice for the third party. Alternatively, it is possible to use gold as the material of the third part. The third part can contain several sections, each connected to a section of the second part of the heating element.
    [0020] There may be an overlap between the different parts of the heating element, in order to ensure a good electrical connection. For example, the first and third parts may be partially above or below the second part. In addition, the heating element may contain more than three distinct parts.
    [0021] The heating substrate is favorably formed by an electrically insulated material and can be a ceramic material, such as zirconia or alumina. The heating substrate can provide a mechanically stable support for the heating element over a wide temperature range, and can provide a rigid structure suitable for insertion into an aerosol-forming substrate. The heating substrate may have a flat surface on which the heating element is positioned and a tapered end configured to allow insertion into an aerosol-forming substrate. The heating substrate has, favorably, a thermal conductivity less than or equal to 2 Watts per meter per Kelvin.
    [0022] In one embodiment, the first part of the heating element is formed by a material that has a defined relationship between temperature and resistance. This allows the heater to be used to heat the aerosol-forming substrate and to monitor the temperature during use. The first part has a favorable temperature coefficient of resistance higher than that of the second part. This ensures that the resistance value of the heating element predominantly reflects the temperature of the first part of the heating element. Platinum has been found to be a good choice for the first part of the heating element.
    [0023] The first part of the heating element is favorably distant from the heater support. The part of the heater that lies between the first part of the heating element and the heater support has a favorable thermal gradient between a higher temperature in the first part of the heating element and a lower temperature in the heater support. The distance between the first part of the heating element and the heater support is chosen to ensure a sufficient drop in temperature. However, it is also advantageous that the distance is not greater than necessary, in order to reduce the size of the heater assembly and ensure maximum strength for the heater assembly. The larger the size of the heater after the heater support, the greater the tendency to break or bend if dropped, or during several insertions and withdrawals on solid aerosol-forming substrates.
    [0024] Favorably, and under normal operating conditions, when the first part of the heating element is at a temperature of 300 to 550 degrees centigrade at approximately the points of contact with the heater support, the second part is at a temperature less than 200 degrees centigrade. "Normal operating conditions" in this context means standard ambient pressure and temperature, that is, a temperature of 298.15 K (25 ° C, 77 ° F) and an absolute pressure of 100 kPa (14.504 psi, 0.986 atm). Normal operating conditions include operation of the heater assembly when positioned within an aerosol generating device housing, or outside an aerosol generating device housing.
    [0025] Favorably, the heater assembly is configured in such a way that if the maximum temperature of the first part is T1, the ambient temperature will be T0, and the temperature of the second part of the heating element in contact with the heater support will be T2 , then: (T1-T0) / (T2-T0)> 2
    [0026] The heating set may contain one or more layers of material covering the heating element. Favorably, a protective layer formed, for example, by glass, can be provided on the heating element, in order to prevent oxidation or other type of corrosion of the heating element. The protective layer can completely cover the heating substrate. The protective layer, or other layers, can also provide a more adequate thermal distribution in the heater and can facilitate cleaning of the heater. An underlying layer of material, such as glass, can also be provided between the heating element and the heating substrate in order to improve the thermal distribution over the heater. The underlying layer of material can also be used to enhance the process of forming the heating element.
    [0027] The dimensions of the heater can be chosen according to the application of the heating set, and it is necessary to clarify that the width, length and thickness of the heater can be selected independently. In one embodiment, the heater is basically blade-shaped and has a tapered end for insertion into an aerosol-forming substrate. The heater can have a length of approximately 10 mm to 30 mm and, favorably, from 15 mm to 25 mm approximately. The surface of the heater, on which the heating element is positioned, can have a width of approximately 2 mm to 10 mm and, favorably, from 3 mm to 6 mm approximately. The heater can be approximately 0.2 mm to 0.5 mm thick, and preferably 0.3 to 0.4 mm thick. The active heating area of the heater, corresponding to the part of the heater in which the first part of the heating element is positioned, can have a length of 5 mm to 20 mm and, favorably, from 8 mm to 15 mm. The heater support can come in contact with the heater in a space of 2 mm to 5 mm and, favorably, in a space of approximately 3 mm. The distance between the heater support and the first part of the heating element can be at least 2 mm and, favorably, at least 2.5 mm. In a preferred embodiment, the distance between the heater support and the first part of the heating element is 3 mm.
    [0028] In a second aspect of the invention, there is an aerosol generating device characterized by: a housing, a heating set, according to the first aspect of the invention, the heater support being coupled to the housing, a electrical power source connected to the heating element, and a control element configured to control the power supply from the power source to the heating element;
    [0029] the housing defining a cavity that surrounds the first part of the heating element, and the cavity is configured to receive an aerosol forming article containing an aerosol forming substrate.
    [0030] As used here, an 'aerosol generating device' is related to a device that interacts with an aerosol-forming substrate in order to generate an aerosol. The aerosol forming substrate can be part of an aerosol generating article, for example, part of a smoking article. An aerosol generating device can be a smoking device that interacts with an aerosol forming substrate of an aerosol generating article in order to generate an aerosol that can be directly inhaled into a user's lung through the user's mouth. An aerosol generating device can be a cigarette holder.
    [0031] The heater support can form a surface that closes one end of the cavity.
    [0032] The device is preferably a portable or handheld device, which can be held comfortably between the fingers of a hand. The device can have a basically cylindrical shape and a length of 70 to 120 mm. The maximum diameter of the device is preferably 10 to 20 mm. In one embodiment, the device has a polygonal cross section and a protruding button on one side. In this mode, the diameter of the device is between 12.7 and 13.65 mm measured from a flat face to an opposite flat face; between 13.4 and 14.2 measured from one edge to an opposite edge (that is, from the intersection of two faces on one side of the device to a corresponding intersection on the other side), and between 14.2 and 15 mm measured from one top of the button to an opposite flat bottom face.
    [0033] The device can be an electrically heated smoking device.
    [0034] The device may include other heaters, in addition to the heater assembly, according to the first aspect. For example, the device may include an external heater positioned around a perimeter of the cavity. An external heater can take any suitable shape. For example, an external heater can take the form of one or more flexible heating sheets on a dielectric substrate, such as polyimide. The flexible heating sheets can be shaped to fit the perimeter of the cavity. Alternatively, an external heater may take the form of one or more metal grids, a flexible printed circuit board, a molded interconnect device (MID), a ceramic heater, a flexible carbon fiber heater, or it can be formed using a coating technique, such as plasma vapor deposition, on a substrate in a suitable manner. An external heater can also be formed using a metal that has a definite relationship between temperature and resistivity. In an example of such a device, the metal can be formed as a strip between two layers of suitable insulating materials. An external heater formed in this way can be used both to heat and to monitor the temperature of the external heater during operation.
    [0035] The power source can be any suitable power source, for example, a DC voltage source, such as a battery. In one embodiment, the power source is a lithium-ion battery. Alternatively, the power source can be a nickel-metal hydride battery, a nickel-cadmium battery or a lithium-based battery, for example, lithium-cobalt, lithium-iron-phosphate, lithium titanate or a polymer battery of lithium.
    [0036] The control element can be a simple key. Alternatively, the control element may be an electrical circuit and may be formed by one or more microprocessors or microcontrollers.
    [0037] In a third aspect of the invention, there is an aerosol generating system characterized by an aerosol generating device, according to the second aspect of the invention, and one or more aerosol forming articles configured to be received in the cavity of the aerosol generating device.
    [0038] The aerosol forming article may be a smoking article. During operation, a smoking article containing the aerosol forming substrate may be partially contained within the aerosol generating device.
    [0039] The smoking article can be substantially cylindrical. The smoking article can be substantially elongated. The smoking article can have a length and a circumference substantially perpendicular to the length. The aerosol forming substrate can be substantially cylindrical in shape. The aerosol forming substrate can be substantially elongated. The aerosol forming substrate can also have a length and circumference substantially perpendicular to the length.
    [0040] The smoking article can have a total length between about 30 mm and about 100 mm. The smoking article can have an outside diameter between about 5 mm and about 12 mm. The smoking article may contain a filter plug. The filter plug may be located at a downstream end of the smoking article. The filter plug may be cellulose acetate. In one embodiment, the filter plug is about 7 mm long, but it can be between about 5 mm and about 10 mm long.
    [0041] In one embodiment, the smoking article has a total length of approximately 45 mm. The smoking article can have an outside diameter of approximately 7.2 mm. In addition, the aerosol forming substrate can be approximately 10 mm long. Alternatively, the aerosol-forming substrate may be approximately 12 mm long. Furthermore, the aerosol forming substrate can have a diameter between about 5 mm and about 12 mm. The smoking article may contain an outer paper wrapper. In addition, the smoking article may contain a separation between the aerosol forming substrate and the filter plug. The separation can be about 18 mm, but it can be in the range of about 5 mm and about 25 mm.
    [0042] The aerosol-forming substrate may be a solid aerosol-forming substrate. Alternatively, the aerosol-forming substrate may contain both solid and liquid components. The aerosol-forming substrate may comprise a tobacco-containing material, containing volatile tobacco flavor compounds, which are released from the substrate upon heating. Alternatively, the aerosol-forming substrate may contain a non-tobacco material. The aerosol forming substrate may also contain an aerosol former which facilitates the formation of a dense and stable aerosol. Examples of suitable aerosol builders are glycerin and propylene glycol.
    [0043] If the aerosol-forming substrate is a solid aerosol-forming substrate, the solid aerosol-forming substrate may contain, for example, one or more of the following items: powder, granules, pellets, pieces, spaghetti, strips or leaves containing one or more of the following items: herbal leaf, tobacco leaf, fragments of tobacco twigs, reconstituted tobacco, homogenized tobacco, extruded tobacco, reconstituted leaf tobacco (cast leaf) and expanded tobacco. The solid aerosol-forming substrate may be in loose form or may be supplied in a suitable container or cartridge. Optionally, the solid aerosol-forming substrate may contain additional volatile flavoring compounds from tobacco or non-tobacco derivatives, to be released upon heating of the substrate. The solid aerosol-forming substrate may also contain capsules which, for example, include the additional volatile tobacco flavoring compounds or non-tobacco derivatives, and such capsules may melt while heating the solid aerosol-forming substrate.
    [0044] As used here, homogenized tobacco refers to the material formed by the agglomeration of particulate tobacco. The homogenized tobacco can be in the form of a leaf. The homogenized tobacco material may have an aerosol-forming content of more than 5% by weight in dry weight. Alternatively, the homogenized tobacco material can have an aerosol-forming content of between 5% and 30% dry weight. It is possible to form sheets of homogenized tobacco material by agglomerating tobacco particles obtained by milling or combining some other form of tobacco leaf blade and tobacco leaf branches. As an alternative, or in addition to that mentioned above, the leaves of the homogenized tobacco material may contain tobacco powders, tobacco residues and other particulate tobacco by-products formed during, for example, the treatment, handling and shipping of the tobacco. Leaves of homogenized tobacco material may contain one or more intrinsic binders, that is, endogenous tobacco binders, one or more extrinsic binders, that is, exogenous tobacco binders, or a combination of them, in order to help agglomerate the particles of tobacco; alternatively, or in addition to the items mentioned, the sheets of homogenized tobacco material may contain other additives including, but not limited to, fibers and tobacco and non-tobacco, aerosol builders, humectants, plasticizers, flavorings, fillers, aqueous and non-aqueous solvents and combinations of these.
    [0045] Optionally, the solid aerosol forming substrate can be supplied or incorporated into a thermally stable carrier. The carrier can take the form of powder, granules, pellets, pieces, spaghetti, strips or leaves. Alternatively, the carrier can be tubular and contain a thin layer of the solid substrate deposited on its inner surface and / or on its outer surface. Such a tubular carrier can be formed, for example, of paper, or paper-like material, a non-woven carbon fiber blanket, a low-mass open-mesh wire mesh, a perforated metal sheet, or any other thermally polymeric matrix stable.
    [0046] In a particularly preferred embodiment, the aerosol-forming substrate is formed by a crumpled sheet of homogenized tobacco material. As used here, the term 'crumpled sheet' indicates a sheet with several roughly parallel edges or corrugations. Preferably, when the aerosol generating article has been assembled, the basically parallel edges or corrugations will extend along, or parallel to, the longitudinal axis of the aerosol generating article. This favorably facilitates the collection of the crumpled sheet of homogenized tobacco material in order to form the aerosol-forming substrate. However, it will be more appropriate that the crumpled sheets of homogenized tobacco material for inclusion in the aerosol-generating article may, as an alternative, or in addition to the aforementioned, have several edges or corrugations basically parallel and arranged at an acute or obtuse angle in relation to to the longitudinal axis of the aerosol generating article, when the aerosol generating article has been assembled. In certain embodiments, the aerosol-forming substrate may contain a sheet of homogenized tobacco material that has a basically uniform texture on practically its entire surface. For example, the aerosol-forming substrate may contain a crumpled sheet of homogenized tobacco material with several edges or corrugations that are basically parallel and evenly spaced across the entire width of the sheet.
    [0047] The solid aerosol-forming substrate can be deposited on the surface of the carrier in the form of, for example, a sheet, foam, gel or paste. The solid aerosol-forming substrate can be deposited over the entire surface of the carrier, or alternatively, it can be deposited in a structure, in order to provide a non-uniform flavor release during use.
    [0048] The aerosol generating system is a combination of an aerosol generating device and one or more aerosol generating articles for use with the device. However, the aerosol generating system may include additional components, for example, a charging unit for recharging an electrical power source integrated into an electric or electrically driven aerosol generating device.
    [0049] In a fourth aspect of the invention, there is a method of manufacturing a heating set characterized by:
    [0050] provide a heating substrate;
    [0051] deposit one or more heating elements with electrical resistance on the substrate, each heating element being characterized by a first part and a second part, configured in such a way that, when an electric current passes through the heating element, the first part is heated to a temperature higher than the temperature of the second part, as a result of the electric current, the first part of the heating element being deposited in a heating area of the heating substrate, and the second part of the heating element being deposited in a support area for the heating substrate; and
    [0052] mold a heater support in the support area of the heater substrate.
    [0053] In a favorable way, the heater support is formed by injection molding. The heater support can be formed from an injection molded polymer, such as PEEK.
    [0054] In a favorable way, the heating substrate basically has a blade shape. The components of the heating assembly can be described with respect to the first aspect of the invention.
    [0055] The molding step can be formed by molding the heater support, so that it surrounds the substrate support area. The heater support can be directly overlaid on the second part of the heating element.
    [0056] In another aspect of the invention, there is a heater for heating an aerosol-forming substrate, the heater being characterized by:
    [0057] a heater formed by a heating element with electrical resistance and a heating substrate;
    [0058] in which the heating element consists of a first part formed by a first material, and a second part formed by a second material different from the first material, configured so that when an electric current passes through the heating element, the the first part is heated to a higher temperature than the second part as a result of the electric current.
    [0059] In yet another aspect of the invention, there is a heating set for heating an aerosol-forming substrate, the heating set being characterized by:
    [0060] a heater formed by a heating element with electrical resistance; and
    [0061] a heater support coupled to the heater;
    [0062] in which the heating element consists of a first part and a second part configured so that when an electric current passes through the heating element, the first part is heated to a higher temperature than the second part, as result of electric current; and wherein the heater support surrounds the second part of the heating element and is formed from a molded polymeric material.
    [0063] Although the present disclosure has been described as referring to different aspects, it must be made clear that the characteristics described in relation to one aspect of the present disclosure can be applied to the other aspects of the disclosure. In particular, aspects of the heater, assembly, system or method of the device, according to one aspect of the invention, can be applied to any other aspect of the invention. In addition, although the disclosure was made with reference to smoking devices, it is necessary to clarify that medical inhaler devices can use the features, equipment and functionality described in this document.
    [0064] Modalities of the invention will be described in detail by way of examples, with reference to the attached drawings, in which:
    [0065] Figure 1 is a schematic diagram of an aerosol generating device;
    [0066] Figure 2 is a schematic cross-section of the front end of an aerosol generating device of the type shown in Figure 1, with the heater inserted in a smoking article;
    [0067] Figure 3 is a schematic illustration of a heater, according to the present invention;
    [0068] Figure 4 shows the heater of Figure 3 with a heater support attached;
    [0069] Figure 5 is a cross section of the heater of Figure 3;
    [0070] Figure 6 is an illustration of the temperature profile over a heater of the type shown in Figure 3.
    [0071] In Figure 1, the components of a modality of an electrically heated aerosol generating system 100 are shown in a simplified form. Specifically, the elements of the electrically heated aerosol generating system 100 are not drawn to scale in Figure 1. Elements that are not relevant for understanding this modality have been omitted to simplify Figure 1.
    The electrically heated aerosol generating system 100 is formed by an aerosol generating device having a housing 10 and an aerosol forming article 12, for example a tobacco stick. The aerosol-forming substrate 12 is pushed into the housing 10 to be in thermal proximity to the heater 14. The aerosol-forming substrate will release a variety of volatile compounds at different temperatures. By controlling the maximum operating temperature of the electrically heated aerosol generating device 100 to stay below the release temperature of some of the volatile compounds, the release or formation of these smoke constituents can be prevented.
    [0073] Inside the housing 10 there is an electrical power source 16, for example, a rechargeable lithium-ion battery. A controller 18 is connected to the heater 14, the electrical power source 16 and a user interface 20, for example, a button or display. Controller 18 controls the energy supplied to heater 14 in order to regulate its temperature. Generally, the aerosol-forming substrate is heated to a temperature between 250 and 450 degrees centigrade.
    [0074] Figure 2 is a schematic cross-section of the front end of an aerosol generating device of the type shown in Figure 1, with the heater 14 inserted in the aerosol forming article 12, which in this embodiment is a smoking article. The aerosol generating device is illustrated by interacting with the aerosol generating article 12 for the consumption of the aerosol generating article 12 by a user.
    [0075] The housing 10 of the aerosol generating device defines a cavity, opened at the proximal end (or end of the mouth), for receiving an aerosol generating article 12 for consumption. The distal end of the cavity comprises a heating assembly 24 formed by a heater 14 and a heater support 26. The heater 14 is retained by the heater support 26 so that an active heating area of the heater is located within the cavity. The active heating area of the heater 14 is positioned within a distal end of the aerosol generating article 12 when the aerosol generating article 12 is fully received within the cavity.
    [0076] The heater 14 takes the form of a blade ending at a point. That is, the heater has a dimension of length greater than the dimension of width, which is greater than its dimension of thickness. The first and second sides of the heater are defined by the width and length of the heater.
    [0077] An example of an aerosol forming article, as illustrated in Figure 2, can be described as follows. The aerosol-generating article 12 consists of four elements: an aerosol-forming substrate 30, a support element such as a hollow tube 40, a transfer section 50 and a nozzle filter 60. These four elements are arranged in sequence and with a coaxial alignment, and are grouped together by a cigarette paper 70 in order to form a stick. After grouping, the aerosol forming article is 45 mm long and has a diameter of 7 mm.
    [0078] The aerosol-forming substrate contains a set of tobacco reconstituted into a crumpled sheet and wrapped in filter paper (not shown) in order to form a plug. Reconstituted leaf tobacco includes one or more aerosol builders, such as glycerin.
    [0079] The hollow tube 40 is located immediately adjacent to the aerosol forming substrate 30 and is formed from a cellulose acetate tube. Tube 40 defines an opening with a diameter of 3 millimeters. A function of the hollow tube 40 is to position the aerosol forming substrate 30 towards the distal end 23 of the stick 21, so that it can be in contact with the heater. The hollow tube 40 acts to prevent the aerosol-forming substrate 30 from being forced along the stick towards the nozzle when a heater is inserted into the aerosol-forming substrate 30.
    [0080] The transfer section 50 is formed by a thin-walled tube 18 mm long. The transfer section 50 allows volatile substances released by the aerosol forming substrate 30 to pass through the article towards the nozzle filter 60. The volatile substances can cool within the transfer section in order to form an aerosol.
    [0081] The nozzle filter 60 is a conventional nozzle filter formed by cellulose acetate and with a length of approximately 7.5 millimeters.
    [0082] The four elements identified above are grouped by wrapping them tightly within a cigarette paper 70. The paper in this specific embodiment is a standard cigarette paper with standard properties or classification. The role in this specific embodiment is a conventional cigarette role. The interface between the paper and each of the elements positions the elements and defines the aerosol forming article 12.
    [0083] As the aerosol generating article 12 is pushed through the cavity, the conical tip of the heater comes into contact with the aerosol forming substrate 30. When applying force to the aerosol forming article, the heater penetrates the substrate aerosol-forming material 30. When the aerosol-forming article 12 is in proper contact with the aerosol-generating device, the heater 14 is inserted into the aerosol-forming substrate 30. When the heater is activated, the aerosol-forming substrate 30 is heated and volatile substances are generated or emitted. As the user sucks on the filter of the nozzle 60, air is sucked into the aerosol forming article and the volatile substances condense to form an inhalable aerosol. This aerosol passes through the nozzle filter 60 of the aerosol forming article and into the user's mouth.
    [0084] Figure 3 illustrates in more detail a heating element 14 of the type shown in Figure 2. The heater 14 is formed by an electrically insulated heating substrate 80, which defines the shape of the heating element 14. The heating substrate 80 is formed of an electrically isolated material, which can be, for example, alumina (Al2O3) or stabilized zirconia (ZrO2). It will be clear to someone with common knowledge in the field that the electrically insulated material can be any electrically insulated material, and that many ceramic materials are suitable for use as the electrically insulated substrate. The heating substrate 80 basically has a blade shape. That is, the heating substrate has a length that, in use, extends along the longitudinal axis of an aerosol forming article in contact with the heater, a width and a thickness. The width is greater than the thickness. The heating substrate 80 ends at a point or tip 90 for penetration into an aerosol forming substrate 30.
    [0085] A heating element 82 formed of an electrically conductive material is deposited on a flat surface of the heating substrate 80 using evaporation or any other suitable technique. The heating element is formed in three distinct parts. A first part 84 is formed by platinum. The first part is positioned in the active heating area 91. This is the area of the heater that reaches the maximum temperature and provides heat to an aerosol forming substrate in use. The first part has a U-shape or a closed curve. A second part 86 is formed by gold. The second part is formed by two parallel bands, each one connected to an end of the first part 84. The second part covers the support area 93 of the heater, which is the area in contact with the support of the heater 26, as shown in Figure 4. A third part 88 is formed by silver. The third part is positioned in connection area 95 and provides agglutination pads to which it is possible to attach external wires using a solder paste or other agglutination techniques. The third part is formed by two parallel pads, each connected to an end of one of the parallel bands of the second part 86, on the side opposite the first part 84. The third part 88 is positioned on the opposite side of the support area 93 in relation to the first part.
    [0086] The shape, thickness and width of the first, second and third parts can be chosen in order to provide the desired strength and temperature distribution during use. However, the first part has a considerably greater electrical resistance per unit length than the second and third parts, and as a result, when an electric current passes through the heating element 82, it is the first part that generates most of the heat and therefore reaches the highest temperature. The second and third parts are configured to have a very low electrical resistance and therefore provide very little Joule heating. The total electrical resistance of the heating element is approximately 0.80 Ohms at 0oC, rising to approximately 2 Ohms when the active heating area 91 reaches 400oC. The battery voltage of the lithium-ion battery is approximately 3.7 Volts, so the typical peak current supplied by the power source (at 0oC) is around 4.6 A.
    [0087] Platinum has a resistance coefficient with a positive temperature and therefore the electrical resistance of the first part 84 increases with increasing temperature. Gold and silver have coefficients of resistance at lower temperatures, and the second and third parts will not experience as high a temperature rise as the first part. This means that changes in resistance in the second and third parts will be small when compared to changes in resistance in the first part. As a result, the resistance of the heating element 82 can be used to provide a measurement of the temperature of the first part 84 of the heating element, which is the temperature of the heater part in contact with the aerosol forming substrate. There is an arrangement described in EP2110033 B1 for using a resistance element as a heater and temperature sensor.
    [0088] Figure 4 shows the heater 14 connected to a support of the heater 26 to form a heating set. The heater support 26 is formed by polyether-ether-ketone (PEEK) and is injection molded around the heater in order to surround the support area 93. The heater substrate 80 can be formed with slits or protrusions in the support in order to ensure a solid fixation between the heater support and the heater. In this embodiment, the heater support 26 has a circular cross section in order to receive a circular housing 10 of the aerosol generating device. However, the heater support can be shaped to assume any desired shape and any desired engagement characteristics for connection with other components of the aerosol generating device.
    [0089] Figure 5 is a schematic cross section of the heater in Figure 3. Figure 5 illustrates that there is an overlap between the first, second and third parts of the heating element. The construction of the heater can be described as follows. The heating substrate 80 is covered with layers of glass 92, 96 on the first and second surfaces. This protects the substrate and improves the heat distribution across the heater surface in the active heating area. The gold bands that form the second part 86 of the heating element are deposited on the glass layer 92. The platinum band, which forms the first part 84 of the heating element, is deposited on the glass layer 92, in a ratio of overlap with the gold bands, in order to ensure a contact with low electrical resistance between the first and the second part. The silver connection pads that form the third part 88 of the heating element are also deposited on the glass layer 92, in an overlapping relationship with the gold bands, in order to ensure a contact with low electrical resistance between the third and the second part. Finally, an overlapping glass layer 94 is formed, covering the heating element 82 and protecting the heating element against corrosion. Then, the heater support can be molded around the heater.
    [0090] The heater is configured so that the active heating area, which corresponds to the first part of the heating element, is far from the heater support. The area of the heater that extends into the cavity of the aerosol generating device is called the insertion area 97. The area of the second part 86 of the heating element that extends into the insertion area 97 provides a transfer area of energy.
    [0091] Figure 6 is a diagram 100 showing the heater temperature as a function of the distance along the heater length during the heater operation illustrated in Figure 3. The heater is displayed below the diagram in such a way that the diagram of the heater temperature is aligned with the heater. Ideally, the heater should be warm in the insertion area 97 and cold in the support area 93 and in the connection area 95. An ideal temperature profile is displayed by the dotted line 106. In reality, the temperature profile can never change so abrupt. It is possible to see in the temperature diagram 100 itself that the heater is hotter in the active heating area, in which the first part of the heating element is positioned. The peak temperature is around 420 oC during aerosol generation. In the area of energy transfer between the active heating area and the support area, the temperature drops rapidly. In this modality, in the heater support, it is desirable that the heater temperature is lower than 200oC, as shown in line 102. The maximum temperature allowed in the heater support will depend on the material used to form the heater support. The position of the heater support part closest to the active heating area is displayed as line 104. The heater is configured to ensure that the temperature in heater support 26 is below 200oC when the active heater area reaches its maximum temperature in use. In the example shown in Figure 6, the distance between the platinum part of the heating element and the heater support is 3 mm. This is a sufficient distance to ensure the necessary temperature drop. Gold was chosen as the material for the second part of the heating element because, in addition to its high electrical conductivity, it has a relatively low thermal conductivity, ensuring a rapid drop in temperature between the active heating area and the support area. An additional temperature drop to approximately 50 ° C is also desirable in at least part of the connection area 95, including the third part 88 of the heating element. In particular, it is desirable to minimize the temperature of the element 14 closest to the controller 18, the electrical source 16 and a user interface 20. For example, this temperature reduction will reduce or eliminate the need to correct the thermal variation induced in chips electronics and / or systems containing a controller 18, source 16 and interface 20.
    [0092] The examples of modalities described above exemplify, but are not limiting. Considering the examples of modalities discussed above, other modalities consistent with the examples of modalities mentioned above will now be evident to a specialist in the field.
