    [001] [001] The present invention relates to an aerosol generating device comprising a compartment with a chamber for receiving an aerosol generating article and an induction heater for heating an aerosol forming article received within the chamber of the compartment. The induction heater comprises an induction coil and a heating element, wherein the heating element is disposed within the induction coil.
    [002] [002] This is known to employ different types of heaters in aerosol-generating articles to generate an aerosol. Typically, resistance heaters are employed for heating an aerosol-forming substrate, such as an electronic cigarette liquid. They are also known to provide "heat without burning" devices using resistance heaters, which generate an inhalable aerosol, heating, but without burning an aerosol-forming substrate containing tobacco.
    [003] [003] Induction heaters offer advantages and have been proposed in the above devices. Induction heaters are, for example, described in US 2017/055580 A1. In induction heaters, an induction coil is arranged around a component made of a conductive material. The component can be denoted as a heating element or susceptor. A high frequency AC current is passed through the induction coil. As a result, an alternating magnetic field is created inside the induction coil. The alternating magnetic field penetrates the heating element, thus creating eddy currents within the heating element. These currents lead to a heating of the heating element. In addition to the heat generated by eddy currents, the alternating magnetic field can also cause the susceptor to heat up due to the hysteresis mechanism. Some susceptors may even be of a nature where no or almost no eddy current occurs. In such susceptors, substantially all of the heat generation is due to the mechanisms of hysteresis. The most common susceptors are of this type, where heat is generated by both mechanisms. A more elaborate description of the processes and responsible for the generation of heat in a susceptor, when penetrated by an alternating magnetic field can be found in WO2015 / 177255. Inductive heaters facilitate rapid heating, which is beneficial for the generation of an aerosol during the operation of the aerosol generating device.
    [004] [004] It would be desirable to have an aerosol generating device with an induction heater in which the heating of a consumable can be varied. It would also be desirable to perform a variable heating without adding significant structural complexity to the device.
    [005] [005] According to a first aspect of the present invention, an aerosol generating device is provided which comprises a compartment defining a chamber configured to receive at least a portion of an aerosol generating article. The device further comprises an induction heater for heating an aerosol forming article received within the compartment chamber. The induction heater comprises an induction coil and a heating element, wherein the heating element is disposed within the induction coil. The induction coil and the heating element are configured to be movable with respect to each other between at least a first operable position and a second operable position. Preferably, the inductor coil is movable in relation to the chamber of the compartment.
    [006] [006] An operable position denotes a position in which the heating element penetrates an aerosol-generating article and is heatable. During the operation of the induction heater, an aerosol is generated by the heating element that heats the inserted aerosol generating article.
    [007] [007] The aerosol-forming substrate containing tobacco may be supplied in the form of an aerosol-generating article. The aerosol-generating article can be supplied as a consumable, such as a tobacco stick. In what follows, the aerosol-generating article will be denoted as consumable. These consumables can have an elongated column shape. Such consumable is normally pushed into a cavity in the device chamber. In the chamber, the heating element of the induction heater penetrates the aerosol-forming substrate into the consumable during insertion of the consumable. Since the aerosol-forming substrate in the consumable is used after several cycles of heating the induction heater, the consumable is removed and replaced with a new consumable. The generation of an aerosol depends, among others, on the position of the heating element within the consumable and the shape and temperature of the heating element. For a specific heating element, the position and temperature of the heating element are the main factors for the generation of aerosol. Aerosol is generated by heating the heating element and when air is drawn through the consumable due to a user's drag. The aerosol-forming substrate in the consumable is heated by the heating element and releases volatile components. Then, the air enriched with the volatile components condenses to form an aerosol which is subsequently inhaled by a user.
    [008] [008] Different users may have different preferences, such as the amount of volatile components generated during aerosol generation. The invention makes it possible to control the generation of aerosol by changing the relative positions of the heating element and the induction coil of the induction heater. Varying the relative orientations of the heating element and the induction coil will lead to variations in the effectiveness of the power transfer to the heating element, because the magnetic flux through the heating element depends heavily on the relative orientation of this heating element and the coil, for any frequency and amplitude used for the AC current applied to the induction coil. Thus, a change in the relative orientation of the heating element and the induction coil can affect how hot the heating element can become and how long it will take for the heating element to reach the ideal operating temperature for generating aerosols. In addition, a part of the heating element can be heated to a higher temperature than another part, in which the other part is heated mainly by conduction. Thus, different regions of the substrate could be specifically heated by changing the operating position of the heating element. Consequently, the positioning of the heating element within the consumable can result in a different heating effect and give the individual user a great degree of flexibility in adopting the user experience according to their particular taste and needs.
    [009] [009] Preferably, the aerosol generating device compartment, the consumable inserted in the device chamber, the chamber and the induction coil have the same longitudinal axis or direction that is a central axis along the length of the above components.
    [0010] [0010] The heating element and coil may have an elongated shape. The heating element can be the same length as the coil. The heating element may be in the form of a pin or blade. The heating element can be solid, while the coil can be helically shaped so that the heating element can be arranged inside the coil.
    [0011] [0011] In the first operable position, a first portion of the heating element can be surrounded by the induction coil. In the second operable position, a second portion of the heating element can be surrounded by the induction coil, where the first and second portions of the heating element may not overlap. If the heating element has penetrated a consumable, the first and second portions of the aerosol-forming substrate are positioned adjacent to the portions of the heating element. During the operation of the induction heater, the first portion of the substrate can be heated in the first position of the heating element and the second portion of the substrate can be heated in the second position of the heating element.
    [0012] [0012] The heating element can be movable in relation to the compartment chamber. The heating element can be movable in a longitudinal direction of the chamber. The heating element can penetrate the consumable and then the consumable can be moved by the heating element along the longitudinal direction of the chamber. The aerosol-forming substrate in the consumable can be heated in succession, advancing the heating element, for example, after each user's drag. The user can change the position of the heating element along the longitudinal direction of the chamber.
    [0013] [0013] The aerosol generating device may further comprise a guiding element configured to restrict the movement of the heating element within the chamber.
    [0014] [0014] The aerosol generating device may further comprise a slide actuator configured to move the heating element within the chamber. The sliding actuator can allow movement of the heating element without directly contacting the heating element. The slide driver can be arranged on a side surface of the device compartment in such a way that the driver can be used without opening the device. The connection means can be arranged to connect the actuator to the heating element which is disposed within the device chamber. The connection means can be configured to convert a movement of the slide driver into a movement of the heating element.
    [0015] [0015] The first and second portions of the heating element can be thermally insulated from each other. The two heating regions can be electrically conductive. The two heating regions can be separated from each other by electrically non-conductive material. Essentially, no eddy current can be generated in one of the heating regions, if the other heating region is surrounded by an induction coil through which an AC current flows. The heating regions can be thermally insulated so that one heating region is not heated while the other heating region is heated. Through the heating regions, portions of the aerosol-forming substrate in the consumable can be heated essentially without other portions of the aerosol-forming substrate in the consumable being heated.
    [0016] [0016] The induction coil can be arranged on the walls inside the compartment surrounding the chamber. By placing the induction coil on walls inside the compartment, the induction coil can be protected from contamination and damage. The induction coil can extend essentially over half the length of the chamber in relation to the longitudinal axis of the device. By limiting the length of the induction coil to a fraction of the chamber, as essentially half the length, partial portions of the aerosol-forming substrate in the consumable can be heated. The portion of the heating element that is surrounded by the induction coil can be heated, as eddy currents are generated in this portion of the heating element if an AC current flows through the induction coil. The induction coil can be arranged adjacent to the proximal end of the chamber. The consumable can be inserted at the proximal end.
    [0017] [0017] The heating element can have a length that corresponds to the length of the chamber. After the consumable portion, which has been heated, is depleted (for example, in the sense that a satisfactory aerosol can no longer be generated), the heating element within the consumable can be moved, thus placing the heating element in contact with a new part of the aerosol-forming substrate within the consumable. The heating element can be moved half the length of the chamber in such a way that the consumable portion, which was not heated by the induction heater, is now surrounded by the induction coil and can be heated. Thus, sections of the consumable can be heated by moving the consumable through the heating element through the induction coil.
    [0018] [0018] The induction coil can be movable in a longitudinal direction of the chamber. Similar to the heating element that is being configured as mobile in a longitudinal direction of the chamber, a mobile induction coil can facilitate that different portions of the aerosol-forming substrate in the consumable can be heated. The induction coil can, according to this aspect, surround a fraction of the chamber, as half the length of the chamber. When the consumable is inserted into the chamber and the heating element penetrates the consumable, the induction coil can surround a portion of the consumable that is subsequently heated to generate aerosol. Thereafter, the induction coil can be moved in a longitudinal direction of the chamber in such a way that a different portion of the consumable is surrounded by the induction coil. This different portion of the consumable can then be heated.
    [0019] [0019] The aerosol generating device may comprise a guiding element configured to restrict the movement of the induction coil in relation to the device chamber. A safe movement of the induction coil along the length of the chamber can thus be facilitated.
    [0020] [0020] The heating element can be movable in a transversal direction of the chamber. The transversal direction of the chamber extends perpendicular to the longitudinal direction of the chamber. The heating element can comprise a base section. The heating element can be elongated and extend perpendicular to the base section into the compartment cavity. The base section can be configured to move between a first position where the heating element is aligned with the central axis of the induction coil, and a second position where the heating element is not aligned with the central axis of the induction coil . Thus, the base section can be configured to move the heating element off center with respect to the central axis of the induction coil. The base section can be formed at the base of the heating element for mounting the heating element inside the induction coil. The base section can be made of a thermally insulating material. The base section can be made of an electrically non-conductive material. The base section can allow air to be drawn through the base section.
    [0021] [0021] The base section can comprise a dial. A dial allows the position of the heating element in relation to the central axis of the induction coil to be changed by rotating the dial. The base section can include a marker indicating the rotation of the display. The base section may, at least partially, extend out of the device compartment in such a way that a user may be able to see and operate the display. A marker on the exposed part of the display can give a visual indication to the user as to what position the display is in and, consequently, what position the heating element is in.
    [0022] [0022] The base section can include a pin to mount the base section. The pin can be arranged off-center with respect to the central axis of the induction coil. The display can be configured to rotate around the pin. In this way, a rotation of the dial can lead to the movement of the heating element away from the central axis of the induction coil. The heating element can be arranged along the central axis of the induction coil in the first operable position. When a consumable is pushed into the device chamber on the heating element, the heating element can penetrate the consumable in the center of the consumable. This arrangement of the heating element can be used in a standard heating effect. When the dial is rotated, the heating element can be moved closer to one side of the induction coil. In this way, if a consumable is inserted into the device chamber after the heating element has been moved by a rotation of the dial, the heating element is inserted outside the center of the consumable. Thus, a different heating effect can be created by a movement of the heating element due to a rotation of the dial. In this regard, side portions of the aerosol forming substrate can be heated by the heating element off center. The position outside the center of the heating element can be the second operable position. The aerosol-forming substrate can be used more efficiently if the consumable is repeatedly removed and inserted into the device chamber, so that different side portions of the aerosol-forming substrate are heated each time. In this regard, the consumable can be rotated during each removal-insertion cycle. In addition, the dial can be rotated slightly during each removal-insert cycle.
    [0023] [0023] The base section can include a sliding element configured to slide in relation to a slot in the compartment. This can allow a linear movement of the heating element from a central position within the induction coil towards an off-center position. The heating effect can be controlled by sliding the heating element between the central position and the off-center position. The movement of the heating element between the central position and the off-center position can be facilitated by the sliding element. The base section and the sliding element can be complementary in shape, such as male and female.
    [0024] [0024] The present invention also relates to an aerosol generating system comprising an aerosol generating article comprising an aerosol generating substrate and an aerosol generating device as described above.
    [0025] [0025] The length of the chamber in relation to the longitudinal axis of the device can be greater than the length of the induction coil, and the induction coil can be arranged adjacent to the proximal end of the chamber. The heating of a consumable inserted in the chamber may vary according to the placement of the consumable inside the chamber.
    [0026] [0026] According to this aspect, the heating element and the induction coil can be arranged stationary, while only the consumable can be moved inside the device chamber. As the induction coil involves only a fraction of the chamber, only a portion of the consumable and the aerosol-forming substrate in the consumable is heated when the consumable is inserted into the chamber. Thereafter, the consumable can be pulled away from the chamber in such a way that the consumable is still located inside the chamber, but no longer extends fully into the chamber. Consequently, the induction coil can now surround a different region than the consumable. In this way, different portions of the consumable can be further heated by pulling the consumable out of the chamber incrementally.
    [0027] [0027] The heating element can be arranged along the longitudinal axis of the induction coil, where the heating element can have a length that is essentially the same as the longitudinal length of the induction coil. In this way, only the heating element that is surrounded by the induction coil can be heated.
    [0028] [0028] The device can comprise a controller. The controller can comprise a microprocessor, which can be a programmable microprocessor. The controller can comprise other electronic components. The controller can be configured to regulate an electrical supply to the induction heater. Electric power can be supplied to the induction heater continuously after system activation or it can be supplied intermittently, such as with a drag-on base. Power can be supplied to the heater by induction in the form of pulses of electric current.
    [0029] [0029] The device can comprise a power supply,
    [0030] [0030] The consumable may comprise an aerosol-forming substrate. The aerosol-forming substrate may comprise a homogenized tobacco material. The aerosol forming substrate may contain an aerosol former. The aerosol forming substrate preferably comprises homogenized tobacco material, an aerosol former and water. The supply of homogenized tobacco material can improve aerosol generation, nicotine content and the aerosol flavor profile generated during heating of the aerosol generating article. Specifically, the homogenized tobacco manufacturing process involves grinding the tobacco leaf, which allows the release of nicotine and flavors by heating in a much more effective way.
    [0031] [0031] The induction heater can be activated by a suction detection system. Alternatively, the induction heater can be activated by pressing an on and off button, held for the duration of the user's drag.
    [0032] [0032] The swallow detection system can be provided as a sensor, which can be configured as an air flow sensor and can measure the air flow rate. The rate of air flow is a parameter that characterizes the amount of air that is sucked through the air flow path of the aerosol generating device by time by the user. The initiation of the puff can be detected by the airflow sensor when the airflow exceeds a predetermined limit. Initiation can also be detected after a user activates a button.
    [0033] [0033] The sensor can also be configured as a pressure sensor to measure the air pressure inside the aerosol generating device that is swallowed through the device's airflow path during a drag.
    [0034] [0034] The aerosol generating device as described above and a consumable can be an electrically operated smoking system. Preferably, the aerosol generating system is portable. The aerosol generating system can be of a size comparable to a conventional cigar or cigarette. The smoking system can have a total length between about 30 millimeters and approximately 150 millimeters. The smoking system can have an outside diameter between approximately 5 mm and approximately 30 mm.

    [0046] [0046] Figure 1 shows an aerosol generating device 10. The aerosol generating device 10 comprises a compartment with a first portion of compartment 12 and a second portion of compartment 14. The first portion of compartment 12 comprises a battery and a controller . The second portion of compartment 14 comprises a chamber 16 for inserting a consumable containing aerosol-forming substrate. The second compartment portion 14 further comprises an induction heater with a heating element 18 and an induction coil 20. The induction coil 20 is arranged within the second portion of compartment 14. The heating element 18 is arranged in a cavity inside chamber 16 surrounded by induction coil 20. The controller is provided to control the supply of electrical energy from the battery to the induction heater. The induction heater is activated by pressing a button
    [0047] [0047] From left to right, Figures 1a, 1b, 1c and 1d are shown. Figure 1a shows the aerosol generating device 10 described above. On a side surface of the aerosol generating device 10, a base section 26 of the heating element 18 is partially visible. The base section 26 is arranged at the base of the heating element 18 and is shaped like a dial. The base section 26 is mounted off-center with respect to the central axis L of the induction coil 20.
    [0048] [0048] Figure 1b shows the aerosol generating device 10 with a second transparent compartment portion 14, such that the induction coil 20 within the second compartment portion 14 can be seen. In Figure 1b, the base section 26 is rotated in such a way that the heating element 18 is arranged along the central axis L of the induction coil 20. In other words, in Figure 1b the heating element is arranged in the first position operable within chamber 16. In Figures 1c and 1d, the base section 26 is rotated in such a way that the heating element 18 is moved away from the center away from the central axis L of the induction coil 20 to a second operable position . Outside the aerosol generating device 10, this movement is indicated by a marker 28 in the base section 26.
    [0049] [0049] Figure 2 shows a detailed view of the heating element 18 and the base section 26. The heating element 18 comprises a tapered tip 30 to facilitate the penetration of a consumable through the heating element 18. The base section 26 in the form of a dial with the marker 28 indicating the position of the base section 26 is shown in detail in Figure 2. In the left part of Figure 2, Figure 2a, the base section 26 is represented in a first operable position in which the element heating element 18 is arranged in a central position aligned along the central axis L of the induction coil 20. In the middle and right parts of Figure 2, Figures 2b and 2c, the base section 26 is rotated in such a way that the element heating element 18 is arranged outside the center. To facilitate this movement, the base section 26 is mounted by means of a pin 30, in which the pin 30 is disposed off center in relation to the central axis L of the induction coil 20. Also shown in Figure 2 is a ring 32 to restrict the movement of the base section 26 and mount the base section 26 between the first and second compartment portions 12,
    [0050] [0050] Figure 3 shows the aerosol generating device 10, in which a consumable 34 is inserted in the aerosol generating device 10. In Figure 3a, consumable 34 has not yet been inserted in the chamber 16 of the device 10 and the heating element 18 is arranged in a first operable position within the chamber 16. By rotating the base section 26, the heating element 18 could, in this phase, be moved to a second operable position, if desired by a user. In Figure 3b, consumable 34 has been inserted into chamber 16 of device 10.
    [0051] [0051] Figure 4 shows a modality of the base section 26, in which the base section 26 is in the form of a sliding element. The base section 26 can be slid into a slot between the first and second compartment portions 12, 14, such that the position of the heating element 18 within the chamber 16 can be changed. The heating element 18 in Figure 4a is aligned along the central axis L of the induction coil 20 in the first operable position. In Figures 4b and 4c, the base section 26 is slid out of the device 10 in such a way that the heating element 18 is disposed in a second operable position. The base section 26 is maintained in an element 36 that has a complementary shape. The base section
    [0052] [0052] Figure 5 shows an embodiment in which the heating element 18 is aligned along the central axis L of the induction coil and is movable along the central axis L. From Figure 5a to 5c, the heating element 18 is moved along the central axis L. The heating element 18 is mounted on a support member 40 to allow movement of the heating element 18. The support member 40 can be moved manually or moved by a mechanism such as a linear motor in the first compartment portion 12.
    [0053] [0053] Figure 5 also shows the heating element 18 arranged in the chamber 16 of the second portion of compartment 14. In this embodiment, the induction coil 20 is not arranged along the entire length 42 of the chamber 16. Instead, the induction coil 20 extends essentially half the length 44 of the chamber 16, while the other half of the length 46 of the chamber is not surrounded by the induction coil 20. The induction coil 20 is arranged close to the proximal end 24 in such a way that when a consumable 34 is inserted into the chamber, only a part of the consumable 34 is surrounded by the induction coil 20 to heat this part of the consumable 34. The mobile heating element 18 can be used after penetrating a consumable 34 to move the consumable 34 partially out of chamber 16. In this way, the consumable part 34 can then be heated, which has not yet been heated by the heating element 18 surrounded by the induction coil 20.
    [0054] [0054] Figure 6 shows the mode of Figure 5, in which a consumable 34 has not yet been inserted in chamber 16 in Figure 6a. In Figure 6b, the consumable 34 is fully inserted in the chamber 16 and on the heating element 18 in such a way that a portion of the consumable 34 surrounded by the induction coil 20 can be heated in a first operable position. In Figure 6c, the consumable 34 has been partially pushed out of the chamber 16 by the movement of the heating element 18. Thus, a different part of the consumable 34 can be heated in a second operable position. In Figure 6d, consumable 34 has been pushed further out of chamber 16 by heating element 18.
    [0055] [0055] Figure 7 shows an embodiment in which the heating element 18 comprises two thermally insulated heating regions 18.1, 18.2. The heating regions 18.1, 18.2 are separated from each other by a separating element 48, which facilitates thermal insulation between the heating regions
    [0056] [0056] Figure 8 shows an embodiment in which the heating element 18 and the induction coil 20 are fixed and only the consumable 34 can be moved inside the chamber 16. The induction coil 20 has a length that corresponds to essentially half the length 44 of the chamber 16. The heating element also has a length that corresponds to essentially half the length 44 of the chamber 16. As can be seen in Figure 8b, the induction coil 20 and the heating element 18 are arranged adjacent to the proximal end 24 of device 10. When a consumable 34 is fully inserted into chamber 16 and pushed over heating element 18, a first portion of consumable 34 of length 44 is heated. Thereafter, the consumable can be partially removed from the chamber 16 in such a way that a second portion of the consumable 34 can be heated.
    [0057] [0057] Figure 9 shows a mode in which a sliding actuator 50 is represented to move the heating element
    [0058] [0058] Figure 10 shows the induction coil 20 being arranged as being movable along the central axis L. The second compartment portion 14 is configured as a movable portion on which the induction coil 20 is arranged. The first portion of compartment 12 forms the chamber 16 and the second portion of compartment 14 is configured as slidable along the first portion of compartment 12, see Figures 10a to 10c. This sliding action can be facilitated by a guiding element. When a consumable 34 is inserted into chamber 16, different portions of consumable 34 can be heated depending on the position of the induction coil 20. Similar to Figure 7, the heating element 18 can include heating regions 18,1, 18,2 with a length corresponding to the length of the induction coil 20, such that only the heating region surrounded by the induction coil is heated at a time.
    [0059] [0059] The invention is not limited to the described modalities. One skilled in the art will understand that the characteristics described in the context of the different modalities can be combined within the scope of the invention.
