[0001] This application relates to the field of atomization technology, and more specifically, to an aerosol generating device. Background Technology

[0002] Aerosol generating devices employing heated non-combustible technology use heating components that atomize aerosol products upon energization to form aerosols. In related technologies, the airflow channel of this type of aerosol generating device is generally constructed using either a side-inlet or top-inlet configuration. For side-inlet aerosol generating devices, users may easily block the air inlet while holding the device during inhalation, hindering airflow. For top-inlet aerosol generating devices, aerosols generated during the preheating stage tend to overflow through the airflow channel, resulting in aerosol waste. Utility Model Content

[0028] To provide a clearer understanding of the technical features, objectives, and effects of this application, the specific embodiments of this application are now described in detail with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0033] Figures 1 to 8 An aerosol generating device 1 according to one embodiment of this application is shown, which can perform low-temperature baking and heating on an aerosol generating article 2 inserted therein to release the aerosol in the aerosol generating article 2 in a non-combustible state. The aerosol generating device 1 may include a housing 10, a heating element 20, a support member 30, a gas guide tube 40, a battery cell 50, and an electronic control component 70. The housing 10 defines an insertion port 11 through which the aerosol generating article 2 can be at least partially inserted into the aerosol generating device 1. The heating element 20, the support member 30, the gas guide tube 40, the electronic control component 70, and the battery cell 50 are disposed within the housing 10. The heating element 20 can heat and atomize the aerosol generating article 2 after being energized. The support member 30 is disposed at the end of the heating element 20 away from the insertion port 11, and is used to support the heating element 20 and the aerosol generating article 2 located within the heating element 20. The gas guide tube 40 is a channel for constructing gas flow. The electrical control component 70 is electrically connected to the heating component 20 and the battery cell 50, respectively, and is used to control the operation of the aerosol generating device 1. The battery cell 50 is used to provide electrical energy for the operation of the aerosol generating device 1.

[0034] It should be understood that the aerosol generating device 1 can be used in the fields of medical, beauty, health care, and electronic atomization. The aerosol generating product 2 can use a solid matrix, which may include solid sheet-like, filamentous, or leaf-like atomizing materials. Specifically, it may include one or more of the following: powder, granules, fragments, strips, or flakes of tobacco, vanilla leaves, tea leaves, mint leaves, or other plant leaves. The atomizing material may also contain additional volatile flavor compounds to be released when the matrix is ​​heated. Of course, the aerosol generating product 2 may also include a liquid matrix or a paste matrix, such as oils or liquid medicines with added flavoring components.

[0035] like Figures 1 to 3 As shown, the housing 10 is generally longitudinally elongated cylindrical, with its insertion port 11 located at one axial end. The heating element 20 defines a cylindrical heating space 200, one end of which is connected to the outside via the insertion port 11, so that the aerosol generating article 2 can be at least partially inserted into the heating space 200 through the insertion port 11 and heated by the heating element 20. The aerosol generating article 2 is cylindrical.

[0036] Understandably, the housing 10 can also be configured as a polygonal column, an elliptical column, an irregular column, an ellipsoid, a sphere, an irregular shape, or other shapes. The insertion port 11 can also be located on the side of the housing 10 or other positions. The aerosol generating product 2 can also be configured as an elliptical column, a flat sheet of various shapes, a polygonal column, an irregular column, or other shapes. The outer contour of the heating space 200 can correspond to the shape of the aerosol generating product 2, or it can be configured as a different shape.

[0037] like Figure 3 As shown, in some embodiments, the end of the housing 10 furthest from the inlet 11 defines at least one air inlet 12. The air duct 40 defines a first air passage P1, which is connected to both the heating space 200 and the air inlet 12, thereby forming a through-flow channel P within the aerosol generating device 1. During use, the user can draw external gas into the airflow channel P through suction, carrying away the aerosol generated by the aerosol generating product 2 within the heating space 200, and then drawing it out through the inlet 11.

[0038] Specifically, the heating element 20 can be coaxially arranged inside the housing 10, and the air duct 40 is arranged along the axial direction of the housing 10 between the air inlet 12 and the heating element 20. The airflow channel P is connected to the heating space 200 from the end of the heating space 200 away from the inlet 11.

[0039] This application, by setting up an air guide tube 40, can effectively gather air while isolating surrounding harmful substances or impurities, ensuring the user's suction experience.

[0040] This application addresses the issue of air inlet 12 by placing it at the end of housing 10 away from inlet 11. This avoids the user blocking the air inlet 12 when handling the aerosol generator 1, compared to placing it on the side wall of housing 10, thus ensuring unobstructed airflow passage P. Furthermore, placing it at the end where inlet 11 is located reduces aerosol overflow from air inlet 12 during the preheating stage, minimizing aerosol waste.

[0041] This application shortens the air intake path of the airflow channel P by connecting the first air passage P to the end of the heating space 200 away from the inlet 11, improving the user's inhalation experience and ensuring efficient overall aerosol delivery. It also allows the gas to directly reach the bottom of the heating space 200 through the first air passage P and enter the aerosol generating product 2 to contact the atomizing medium, avoiding heat loss due to cold air input and improving power consumption efficiency.

[0042] In some embodiments, the heating element 20 may include a pot body and a heating structure (not shown) disposed on the pot body. The pot body may be made of a heat-resistant material, such as quartz, ceramic, or heat-resistant glass. The heating structure is electrically connected to the electronic control component 70, so that the battery cell 50 can supply power to the heating structure through the electronic control component 70. The heating structure may be layered or mesh-like, disposed on the inner and / or outer wall of the pot body, and may specifically employ resistance wire, infrared radiation coating, etc., without specific limitations.

[0043] like Figure 2 and Figure 3 As shown, in some embodiments, the support 30 defines a liquid storage chamber 320 that communicates with the heating space 200 for containing residual liquids such as condensate during the suction process, thereby preventing leakage of impurities.

[0044] It should be understood that during use, the aerosol generating device 1 will tilt and change depending on the angle at which the user holds it. Therefore, the condensate accumulated during the suction process may leak into the air intake section of the airflow channel P, thus affecting the taste of the suction.

[0045] This application, by setting up a liquid storage chamber 320, can collect condensate and prevent it from entering the air guide tube 40, so as to ensure that the taste of the suction is not affected by the condensate.

[0046] Specifically, the end of the air duct 40 near the heating component 20 is connected to the support 30, and its first air passage P1 is connected to the liquid storage chamber 320 for air conduction, and is connected to the heating space 200 for air conduction through the liquid storage chamber 320.

[0047] See also Figure 4In some embodiments, the support member 30 may be generally cylindrical with one open end, including a support portion 31 and a liquid storage portion 32. The support portion 31 is coaxially fitted to the end of the heating element 20 away from the insertion port 11, and is used to support the heating element 20. The liquid storage portion 32 is disposed at the end of the support portion 31 opposite to the heating element 20, and defines a liquid storage cavity 320. The support portion 31 defines a support space 310, which can be connected and communicated with the heating space 200 to form an integral chamber. At least a portion of the aerosol generating article 2 can be inserted into this chamber.

[0048] Of course, the support member 30 can also be set to other shapes such as polygonal cylinder, hemisphere, or irregular shape.

[0049] It should be understood that the fit between the support portion 31 and the heating element 20 can be achieved by providing stepped surfaces on the support portion 31 and / or the heating element 20 to abut against each other. Alternatively, the two can be assembled through snap-fit ​​connections, threaded connections, interference fits, integral molding, etc. No specific limitations are made here.

[0050] It is necessary to understand that, such as Figure 1 As shown, the aerosol generating article 2 may include a medium section 201, a sealing section 202, and a suction section 203. The medium section 201 is coaxially disposed between the sealing section 202 and the suction section 203. When the aerosol generating article 2 is inserted into the chamber, at least a portion of the sealing section 202 is located within the support space 310, at least a portion of the medium section 201 is located within the heating space 200, and at least a portion of the suction section 203 is located outside the chamber.

[0051] The sealing section 202 provides some obstruction to the condensate, thereby reducing leakage during the suction process. This application utilizes the support section 31 and defines the support space 310 to accommodate the sealing section 202, thus improving the utilization rate of the heating space 200.

[0052] Furthermore, such as Figure 2 and Figure 4 As shown, the support member 30 also defines an air guide hole 33, which can be located at the position where the liquid storage part 32 and the support part 31 are connected, and is connected to the support space 310 and the liquid storage chamber 320 respectively, so that the first air passage P1 can be connected to the heating space 200 in sequence through the liquid storage chamber 320, the air guide hole 33, the support space 310.

[0053] In some embodiments, the wall where the air guide hole 33 is located (i.e., the connecting wall between the support portion 31 and the liquid storage portion 32) can serve as a limiting structure, abutting against and limiting the aerosol generating article 2 when it is inserted into place. Of course, as Figure 2 and Figure 5As shown, at least one support structure 34 can also be provided on the side of the wall facing the support space 310, for abutting against the end of the sealing section 202 of the aerosol generating product 2 away from the medium section 201, so as to reduce the sealing of the end of the aerosol generating product 2 while abutting and limiting, improve the uniformity of airflow entering the aerosol generating product 2, and avoid the airflow from concentrating in a local position inside it, which would affect the sucking taste.

[0054] Specifically, the support structure 34 can adopt various shapes of lugs, protrusions, stiffeners, etc., or it can adopt various shapes of grooves on the side of the wall facing the support space 310, etc., without specific limitations.

[0055] In some alternative embodiments, the support member 30 may also include only a liquid storage section 32, which can be directly connected to the heating space 200. In this embodiment, the liquid storage section 32 can be mutually matched and limited by means of snap-fit ​​connection, threaded connection, connector connection, stepped surface abutment, etc. At the same time, the liquid storage section 32 or the support member 30 can also be provided with a support structure 34 to limit the insertion of the aerosol generating product 2.

[0056] like Figures 2 to 4 and Figure 6 As shown, in some embodiments, the support member 30 may have a first connection hole 321 defined on it, and the air guide tube 40 is connected to the first connection hole 321 of the support member 30. The first air passage P1 can be connected to the liquid storage chamber 320 through the first connection hole 321.

[0057] Furthermore, the first connection hole 321 is connected to the position of the liquid storage cavity 320, located between the end of the liquid storage cavity 320 near the heating component 20 and the end away from the heating component 20.

[0058] It should be understood that the first connection hole 321 connects to the liquid storage chamber 320, located between the end of the liquid storage chamber 320 near the heating element 20 and the end away from the heating element 20. This can be understood as, when the aerosol generating device 1... Figure 2 and Figure 3 When positioned at the indicated angle, the first connecting hole 321 penetrates the horizontal position of the chamber wall of the liquid storage cavity 320, higher than the horizontal position of the bottom wall of the liquid storage cavity 320, and lower than the horizontal position of the top wall of the liquid storage cavity 320. Alternatively, it can be understood that the position of the first connecting hole 321 penetrating the chamber wall of the liquid storage cavity 320 is axially aligned with the housing 10, located between two opposing end walls of the liquid storage cavity 320 axially aligned with the housing 10.

[0059] By defining the position of the first connection hole 321 connecting to the liquid storage chamber 320, the condensate flowing into the liquid storage chamber 320 can accumulate at the bottom of the liquid storage chamber 320 under the action of gravity, preventing leakage into the first air passage P1 through the first connection hole 321. While ensuring airflow, it further ensures the cleanliness of the air intake section of the airflow passage P, improving the long-term user experience.

[0060] Specifically, such as Figure 2 , Figure 4 and Figure 6 As shown, a boss structure 35 may be provided in the liquid storage part 32 of the support member 30, and the first connecting hole 321 may penetrate the boss structure 35 so that its gas outlet is located on the boss structure 35, which is higher than the bottom wall of the liquid storage cavity 320.

[0061] In some other alternative embodiments, the first connection hole 321 may also be provided on the side wall of the liquid storage part 32 parallel to the axis of the housing 10. Alternatively, the first connection hole 321 may also be provided on the support part 31 and communicate with the support space 310, with the air guide tube 40 connected to the support part 31 and directly connected to the bottom end of the support space 310 through the first connection hole 321.

[0062] It should be understood that the air guide tube 40 is connected to the first connecting hole 321 of the support member 30. The support member 30 may have a connecting portion 36 protruding from its outer side, with the end of the air guide tube 40 fitted onto the connecting portion 36. This achieves connection while improving the airtightness of the connection and reducing gas leakage. Alternatively, the end of the air guide tube 40 may pass through the first connecting hole 321. Or, the end of the air guide tube 40 may be connected to the wall of the first connecting hole 321 via a sealing sleeve or other connecting component. No specific limitations are made here.

[0063] In some embodiments, when the end of the vent pipe 40 passes through the first connecting hole 321, and the first connecting hole 321 penetrates the bottom wall of the liquid storage section 32, the end of the vent pipe 40 can extend into the liquid storage chamber 320. In this embodiment, the end of the vent pipe 40 located in the liquid storage chamber 320 can be considered as the outlet end of the first connecting hole 321. The end of the vent pipe 40 extending into the liquid storage chamber 320 can be considered as the outlet end of the first connecting hole 321 located between the heating element 20 and the chamber wall of the liquid storage chamber 320 away from the heating element 20.

[0064] like Figure 3 and Figure 8As shown, in some embodiments, the electronic control component 70 may include a main control board 71 and an airflow sensor 72. The airflow sensor 72, the heating element 20, and the battery cell 50 are electrically connected to the circuitry on the main control board 71. The airflow sensor 72 is used to determine the user's inhalation status by detecting the airflow in the airflow channel P, and then to determine the temperature change within the heating element 20 based on the user's inhalation. This allows for more flexible and accurate control of the heating element 20's heating of the aerosol-generating product 2, ensuring the user's inhalation experience.

[0065] The aerosol generating device 1 can also define a detection airway, which can be connected to the airflow channel P. The airflow sensor 72 is connected to the airflow channel. During user operation, negative pressure can be generated in the detection airway as the user inhales. The airflow sensor 72 determines the user's inhalation status by monitoring the changes in negative pressure in the detection airway.

[0066] It should be understood that in related technologies, the heating temperature of the heating component 20 is usually monitored using thermocouples. This setup requires a metal connection at the airflow channel P for signal detection, which imposes significant limitations on the design and space of the airflow channel P, hindering the miniaturization of the aerosol generating device 1.

[0067] This application uses an airflow sensor 72 to replace the temperature-measuring thermocouple. By detecting the user's suction, the temperature change of the heating element 20 can be detected, reducing the space occupied and reducing the restrictions on the internal components and airflow channel P.

[0068] It should be understood that the airflow sensor 72 can be implemented using existing MEMS (silicon microscopy), microphones, etc., and no specific limitations are made here.

[0069] like Figure 3 As shown, in some embodiments, the end of the detection airway away from the airflow sensor 72 is connected to the air guide of the liquid storage chamber 320 so as to detect the negative pressure by means of the airflow change in the liquid storage chamber 320.

[0070] It is important to understand that due to the varying dimensions of different sections of the airflow channel P, a significant pressure change occurs in the liquid storage chamber 320 during the user's suction process, creating a negative pressure chamber as the airflow rapidly passes through. After suction is completed, the internal pressure will return to atmospheric pressure levels as the airflow channel P connects to the outside environment. By connecting the detection airway to the liquid storage chamber 320, the airflow sensor 72 can more accurately detect pressure changes within the liquid storage chamber 320. Simultaneously, the support member 30 facilitates the layout of the detection airway, reduces interference during airflow, further improves the sensitivity of the airflow sensor 72, and thus enhances the accuracy and reliability of signal transmission.

[0071] like Figures 4 to 7 As shown, the support member 30 has an opening 322 at its liquid storage section 32, connecting the liquid storage chamber 320 to the outside. (See also...) Figure 8 The aerosol generating device 1 may further include a sealing element 80, which seals the opening 322 to relatively seal the liquid storage chamber 320. The detection air passage may include a first through hole 81, which extends through the sealing element 80 and is connected to both the liquid storage chamber 320 and the airflow sensor 72.

[0072] Specifically, the opening 322 can be generally distributed on one side wall of the liquid storage section 32, and is in the shape of a window of a certain size. The sealing member 80 can be provided in the form of a plate or a block, so as to at least partially interfere with the opening 322 to achieve sealing.

[0073] It should be understood that the position of the first through hole 81 on the seal 80 is such that when the seal 80 is assembled onto the opening 322, the first through hole 81 is located axially between two opposing chamber walls of the liquid storage chamber 320 along the axial direction of the housing 10. During user operation, the end of the first through hole 81 near the liquid storage chamber 320 is horizontally higher than the bottom wall of the liquid storage chamber 320 to prevent liquid from seeping into the airflow sensor 72 through the first through hole 81 and causing damage.

[0074] Furthermore, such as Figure 3 As shown, the end of the first through hole 81 near the liquid storage chamber 320 can be close to the air outlet end of the first connecting hole 321, so as to further improve the detection effect of the airflow sensor 72 on negative pressure.

[0075] In some alternative embodiments, the opening 322 may also be configured as a through hole, directly connecting and communicating with the airflow sensor 72. In this embodiment, the seal 80 may be configured as a sealing ring, sandwiched between the liquid reservoir 32 and the airflow sensor 72.

[0076] In some other alternative embodiments, the seal 80 may also be provided in a tubular structure, with one end connected to the support 30 to communicate with the opening 322, and the other end connected to the airflow sensor 72.

[0077] like Figure 3 and Figure 8 As shown, in some embodiments, the airflow sensor 72 can be mounted on the main control board 71. The detection airway also includes a second through hole 711, which is connected to the first through hole 81. The second through hole 711 extends through the main control board 71, and the seal 80 seals between the main control board 71 and the support member 30 to ensure relative sealing of the detection airway. The airflow sensor 72 can be disposed on the side of the main control board 71 opposite to the seal 80 and connected to the second through hole 711.

[0078] In some other alternative embodiments, the airflow sensor 72 can also be electrically connected to the main control board 71 via a rigid electrical connection structure such as electrode posts or electrode sheets. In this embodiment, the electrical connection structure can also serve to support the airflow sensor 72.

[0079] In some other alternative embodiments, the aerosol generating device 1 may also be provided with a separate support to support the airflow sensor 72 within the housing 10. In this embodiment, the electrical connection structure may also be a flexible structure such as a wire.

[0080] In some other alternative embodiments, the detection airway may also be connected to the air duct 40.

[0081] It should be understood that the seal 80 may be made of one or more of the following materials: silicone, rubber, TPU (thermoplastic polyurethane), PCTG (polyethylene terephthalate copolymer), PPSU (polyphenylsulfone), PEEK (polyether ether ketone), etc., without any specific limitation.

[0082] It should be understood that the number of these main control boards 71 ​​can be set to one or more as needed, and no specific limit is made here.

[0083] like Figure 2 and Figure 3 As shown, in some embodiments, the airflow channel P further includes a second air passage P2, which connects the first air passage P1 and the air inlet 12. The battery cell 50 can be disposed axially on the side of the air duct 40 away from the heating element 20 in the housing 10. The radial gap between the battery cell 50 and the housing 10 can be regarded as the second air passage P2.

[0084] Specifically, the position of the air duct 40 in the axial direction of the housing 10 can correspond to that of the electronic control component 70, both being roughly located between the battery cell 50 and the heating component 20, in order to improve the rationality of the internal components of the housing 10 and thus improve the utilization rate of the internal space.

[0085] By setting the gap between the battery cell 50 and the housing 10 as the second air passage P2, the axial overlap between the air guide tube 40 and the battery cell 50 can be reduced, the length of the air guide tube 40 can be shortened, and the space occupied inside the housing 10 can be reduced, which is conducive to the miniaturization of the aerosol generating device 1.

[0086] By placing the air duct 40 at the location of the electronic control component 70, it can also protect the electronic control component 70 and prevent condensate, impurities and other substances from leaking onto the electronic control component 70 and causing damage.

[0087] Continue reading Figure 2 and Figure 3In some embodiments, the aerosol generating device 1 further includes a support 60 disposed within the housing 10 for limiting the components within the housing 10.
