    The invention relates to a mouthpiece for an inhaler with the features of the preamble of claim 1.
    Furthermore, an inhaler should be indicated with the features of the preamble of claim 9.
    In addition, a method for operating an inhaler should be specified.
    Furthermore, the use of a mouthpiece and the use of an inhaler for an electric cigarette should be indicated.
    The above-mentioned mouthpieces and inhalers are already known and are shown for example in EP 3136886 A1. However, these mouthpieces or these electrical inhalers or smoking devices have a significant disadvantage. A variety of electric or electronic smoking devices have the ability to automatically start the inhalation-related reaction process to vaporize or atomize the liquid via a reaction member by sucking the user to the electrical smoking device. Thus, no button or switch must be actively activated in order to nebulize or vaporize the liquid. By sucking on the mouthpiece of the electric smoking product, an air flow and / or a negative pressure in the device, whereby a detection device, in the form of a sensor or switch or something similar, is activated. As a result, a circuit is subsequently closed or a signal is emitted to activate the device for vaporizing or atomizing the liquid. This detection device, which detects the suction on the electric smoking product, often sits in direct connection with the main flow channel in the interior of the electric smoking product. The main flow channel serves to deliver the vaporized or atomized liquid through the mouthpiece to the outside to the user. The direct connection of the main flow channel to the liquid container, the vaporization unit and the detection device often makes it difficult to prevent leakage of liquid into the interior of the electric smoking article or also to the outside. If, for example, liquid enters the interior of the electric smoking product, its function may no longer be guaranteed due to the entry of the liquid. The leakage of the liquid to the outside can be harmful to persons, as soon as they come in connection with it, since the liquid can contain, for example, active ingredients, such as nicotine. Furthermore, escaping liquid may cause staining during stowage or storage of the electric smoking product in a trouser pocket or pocket. This is particularly problematic when refillable or exchangeable mouthpieces are used. These are, for example, simply attached to a base body, which serves as a base element. It is particularly difficult to prevent the leakage of liquid. If, for example, the mouthpiece with the liquid container located therein and the evaporation or atomization unit located therein are plugged onto the base segment, there is a closed connection to the base segment and leakage of liquid is thus prevented. However, as soon as the mouthpiece is removed for replacement, leakage of residual liquid often occurs at the interface between the mouthpiece and the base segment. The change of different liquids depending on preference is complicated by this problem, since the remaining liquid in the mouthpiece can escape. In other words: in the prior art, it is often difficult to be able to exchange the mouthpieces just as you like with each other, as you z. B. has a desire to consume another active ingredient or a different taste of the liquid. The systems are often not completely self-contained. A reuse of the mouthpiece is therefore no longer readily possible. The channels which serve for drug or liquid delivery include not only the function of delivering the converted liquid, but also the detection of the air flow to activate the reaction element. This can not be excluded on the device leakage to the outside or inside.
    The object of the invention is to avoid the disadvantages described above and improved over the prior art mouthpiece, an improved inhaler, an improved method for operating an inhaler and the use of such a mouthpiece, such an inhaler and such a method for an electric cigarette specify.
    This is in the mouthpiece according to the invention with the features of claim 1, the inhaler according to the invention with the features of claim 9, in the inventive method with the features of claim 17 and in the inventive use of the mouthpiece with the features of claim 18, in the inventive use an inhaler having the features of claim 19.
    Characterized in that at least one bypass channel is arranged on or in the mouthpiece, which extends along the mouthpiece and the bypass channel relative to the main flow channel, the liquid container, the liquid receiver, the reaction section and the inlet channel is executed closed, creates a reusable, non-leaking, fluid-tight mouthpiece which prevents even after or during use, a dispensing of liquid through the bypass channel or the main flow channel. It is prevented by the main flow to the fluid-tight and not communicating with the main flow channel bypass channel when using the inhaler entry of liquid in the bypass channel.
    It has proved to be advantageous here that the bypass duct extends between a bypass opening located at a suction region of the mouthpiece and an interface, wherein the bypass duct is closed except for the bypass opening and the interface. By this self-contained system no liquid or no condensate or the like from the reaction section passes into the bypass channel. The bypass channel is solely for creating a negative pressure in the mouthpiece and has no direct or indirect connection opening to the primary channels or areas necessary for the conversion of the liquid.
    When the main flow channel is opened by a main flow opening adjacent to the bypass opening at the suction area of the mouthpiece, both the main flow channel and the bypass channel are available to the user as soon as it pulls on the suction area of the mouthpiece. The function of both channels is thus simultaneously but independently guaranteed.
    When the bypass opening and the main flow opening are formed through different openings, leakage of the liquid through the bypass opening may be precluded. Furthermore, no liquid from the main flow opening into the bypass opening, as they are located away from each other. Contamination of the bypass channel by the liquid is thus excluded. The function of the bypass channel thus remains upright.
    If a main air flow in the main flow channel and a separate from the main air flow secondary air flow in the bypass channel can be produced during suction at the suction of the mouthpiece, so both air streams are independent. Thus, a detection device independent of the main air flow may be used, which requires, for example, a lower suction power or a lower pressure to react. Thus, the bypass duct can be implemented by, for example, a smaller diameter in order to use a more sensitive, compact detection device. This is reflected in the compact design of the inhaler. Furthermore, costs can be saved.
    It has also proven to be advantageous for the mouthpiece to have at least one contact element, via which energy-preferably electrical energy-can be transmitted to the reaction element. Thus, the reaction element can be installed closed in the mouthpiece. The reaction element is part of the mouthpiece and is energized in use via the contact element. There are no breakthroughs through which liquid can escape from the mouthpiece in the region of the reaction element. The area is closed, only the contacts of the contact element pass through the closed wall of the mouthpiece to the outside.
    If the reaction element is formed by a preferably electrically operated evaporator or an atomizer, the liquid is converted from the liquid container accordingly, in order to be able to administer the user the liquid together with active ingredients in a converted form.
    When the main flow channel is in a main flow member and the bypass channel is in a stand-alone bypass member of the mouthpiece, the main flow member and the bypass member together forming the mouthpiece, in case of damage to the mouthpiece, either the main flow member or the bypass member may be independently interchanged. Furthermore, for example, for cleaning the bypass element can be easily removed from the mouthpiece. In order to save costs it can also be that the bypass element can be used several times, while the main flow element must be disposed of after the complete evaporation of the liquid from the liquid container. However, the bypass element could also be formed integrally with the remainder of the inhaler. Only the main flow element would be interchangeable in this case. Together, however, the bypass element and the main flow element produce the entire mouthpiece. It would also be possible that the bypass element and the main flow element or even the entire inhaler are integrally formed.
    It has proved to be advantageous in this case that the base segment has a control device, an energy store and a detection device. The detection device is formed by a flow sensor, pressure switch, vacuum sensor or similar electrical contact, which reacts in the production of a secondary air flow accordingly and closes a circuit or the control device gives the message for energizing or energy release to the reaction element. The control device thus recognizes via the detection device that the user sucks on the mouthpiece of the inhaler. All electrical or electronic components are thus installed on the base segment or in the base segment. Only the reaction element is located in the mouthpiece and is brought into contact with the electrical or electronic components located in the base segment via the at least one contact element.
    It has proven to be particularly advantageous that the detection device is formed by a vacuum switch, flow sensor or vacuum sensor. Thus, the release of energy to the reaction element is fully automatically activated as soon as the user sucks on the mouthpiece. An active pressing a button or a similar actuator thus falls away. The reaction element is energized only when the user actually sucks on the mouthpiece. Thus, a longer operating life of the reaction element is guaranteed, since it is only used when it is actually necessary. The evaporation or atomization of the liquid can thus also be better controlled, in particular if parameters have been stored in the control device. For example, if the reaction element is energized for too long and too much atomization or vaporization of the liquid is generated, then too many active substances or flavorings could be released to the user by the liquid that has thus been converted too much, which could, for example, entail unpleasant consequences for the user.
    The following method steps have proved to be advantageous: suction on the mouthpiece of the inhaler by a user, development of a secondary air flow in the bypass channel, simultaneous development of a main air flow in the main flow channel, creation of a negative pressure in the bypass channel and in the main flow channel by sucking the user on the mouthpiece, Passing the negative pressure in the bypass channel to a detection device in the base segment, passing the signal of the detection device to the control device in the base segment, processing the signal of the detection device in the control device and forwarding energy preferably from electrical energy to the reaction element, Reaction of the liquid with the reaction element - preferably evaporation or atomization of the liquid, - transfer of the liquid through the reaction element to the main flow channel and administration to the user, - interruption of the Verabr calibration of the liquid at the end of the suction process by the user by aborting the signal from the detection device.
    Further details and advantages of the present invention will be explained in more detail below with reference to the description of the figures with reference to the exemplary embodiments illustrated in the drawings.
    Show:
    Fig. 1 variant mouthpiece with separate main flow element and
    Sidestream element,
    Fig. 2 bypass element is part of the base segment,
    Fig. 3 mouthpiece and base segment in one piece.
    1 shows the mouthpiece 1 for an inhaler 30 with a main flow channel 2, which is located in a main flow element 5. The bypass duct 3 is located in a separate, separated from the main flow element 5, bypass element 4. It can be seen that the bypass duct 3 has no connection to the main flow channel 2. Thus, leakage of the liquid 9 through the channels located in the main flow element 5 channels can be excluded by the Nebenstromanal 3. In the main flow element 5 is inter alia the liquid container 8, which contains the liquid 9 and emits the liquid receiver 11 to the reaction element 12. The reaction element 12 is located in a reaction section 10 which communicates with the main flow channel 2.
    Through the air inlet opening 6 passes when pulling on the mouthpiece 1, the ambient air into the interior of the mouthpiece 1 and subsequently into the reaction section 10. There, the absorbed by the Liquidaufnehmer 11 Liquid 9 is brought by the reaction element 12 in a nebulized or vaporized state and the Sucking at the mouthpiece 1 is discharged through the main flow channel 2 to the user. This is done by the main air flow FILS. If the main air flow FILS is generated, the air required for this purpose is taken from the environment through the air inlet opening 6. It can be seen that the liquid 9 is in its liquid form or in its converted form only in the main flow element and can not enter the base segment 20 or the bypass duct 3. It can also be seen that the main flow opening 22 and the side opening 23 are spatially separated from each other. Thus, no
    Connection between the main flow opening 22 and the bypass opening 23 are made.
    The converted liquid thus passes out of the mouthpiece 1 only at the main flow opening 22. At the attachment portion 19, the mouthpiece 1 is connected to the base segment. The connection for the transmission of energy, which is necessary for the reaction element 12, takes place via the at least one contact element 13, in this case as electrical contacts. If the mouthpiece 1 is attached to the base segment 20, which takes place via the attachment section 19, an electrical connection is established between the reaction element 12 located in the mouthpiece 1 and the electrical or electronic components located in the base segment 20.
    These electrical or electronic components are, for example, a control device 14 which controls and regulates the degree of nebulization or evaporation on the reaction element 12. Furthermore, in the base segment 20 there is an energy store 15, for example in the form of a lithium polymer or lithium ion battery, which supplies the system with electrical energy. To detect whether a user sucks on the mouthpiece 1 and wants to consume the converted liquid 9, there is a detection device 16 in the base segment 20. This detection device 16 is connected via an interface 18 with the bypass element 4 in connection. Thus, the bypass duct 3 is connected to the base segment 20 via the interface 18 for cooperation with the detection device 16. If the user sucks on the mouthpiece 1, a secondary air flow NLS is generated via the bypass duct 3, which activates the detection device 16. This is related to the control device 14.
    As soon as the detection device 16 is activated, a signal is output to the control device 14, which emits the electrical current located in the energy store 15 via the contact element 13 to the reaction element 12 and energizes it. The liquid present in the Liquidaufnehmer 11 is thus atomized or vaporized and discharged via the main air flow HLS to the user.
    The detection device 16 may be formed, for example, by a pressure switch, a flow sensor, a vacuum sensor or other type of detection device that responds to the secondary air flow. It can also be seen in FIG. 1 that the bypass element 4, the main flow element 5 and the base segment 20 are separate components which can be connected to one another via fastening sections 19. Thus, if necessary, each individual component could be replaced. Due to the closed design of the main flow element 5, it is possible to separate this even with a non-emptied liquid container 8 from the base segment 20. There is no leakage of liquid. Reuse of the mouthpiece 1 is still possible even after a change of the mouthpiece 1 or after disassembly via the mounting portion 19. The base segment 20 is formed by a housing which has a chamber 17 in the interior. This chamber 17 serves to receive the control device 14, the energy accumulator 15 and the detection device 16. By the secondary air flow NLS the suppression or an air flow is generated in this chamber 17, which is detected by the detection device 16.
    2 shows a further variant of the inhaler 30 and the mouthpiece 1. The individual components are provided with the same reference numerals as in FIG. 1, since the basic functions of the individual components described in FIG. 1 correspond to those in FIGS Also to be equated to Fig. 3 variant shown. The difference from the variant shown in FIG. 2 to that shown in FIG. 1 is that the bypass element 4 is integrally connected to the base segment 20 and only the main flow element 5 is connected via the attachment section 19 to the base segment 20 and also to the bypass element 4 can be brought. Since the bypass element 4 can never be contaminated by liquid 9 and therefore does not necessarily have to be cleaned or exchanged, this could thus also be a one-part component of the base segment 20. Thus, the interface 18 shown in FIG. 1 is omitted since the bypass element 4 is not an exchangeable element which can be brought into connection with the base segment 20 via a fastening section 19.
    FIG. 3 shows an inhaler 30, the mouthpiece 1 consisting of a bypass element 4 and a main flow element 5 and also the base segment 20 being made in one piece. This is a cost-effective variant of the inhaler 30, wherein the liquid container 8 can be filled, for example via a filling device 24. The filling device 24 may, for example, be a valve, a flap or the like, via which the liquid can be introduced or filled into the liquid container 8, either in the form of liquid or bound in a capsule.
    Generally speaking, FIGS. 1 to 3 are schematic diagrams that do not allow conclusions as to the geometry or dimensions of the inhaler 30, the mouthpiece 1, the base segment 20, or other components of the system. Thus, the inhaler 30 may have a narrow, cylindrical shape that appears similar to a cigarette. However, this can also be completely different shape.
