[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0021] The following reference Figures 1-2 A detailed description of the aerosol generating apparatus 100 according to embodiments of this application is provided. It is to be understood that the following description is merely illustrative and not intended to limit the scope of this application.

[0022] It should be noted that the aerosol generating device 100 can be used to heat the aerosol generating article. After heating, the aerosol generating matrix in the aerosol generating article can generate aerosols for inhalation by a user. The aerosol generating matrix can include a liquid of at least one aerosol forming material, such as glycerol. In some alternative examples, the aerosol generating matrix can include tobacco extracts or other plant extracts, synthetic alkaloids, or pharmaceutical ingredients. For example, the aerosol forming material may include a combination of nicotine salts, glycerol, propylene glycol, and cooling or flavoring agents. It has been found that aerosol forming materials improve the sensory properties of the aerosol generating matrix by helping to transfer compounds (e.g., flavor compounds) from the aerosol generating material to the consumer.

[0023] like Figure 1 As shown, according to an embodiment of this application, the aerosol generating device 100 can be used to atomize an aerosol generating matrix to generate aerosols for consumption by users.

[0024] like Figures 1-2 As shown, the aerosol generating device 100 may include a housing 10, a battery cell 20, a heating element assembly 30, and a cover 40.

[0025] Specifically, the housing 10 has an internal cavity 11, in which the battery cell 20 is housed. It should be noted that the cavity 11 can also be used to house the battery cell 20 and other internal components to protect them from external environmental influences.

[0026] like Figures 1-2 As shown, the battery cell 20 can provide electrical energy to the aerosol generating device 100. The housing 10 is provided with an opening 12, which communicates with the accommodating cavity 11. The opening 12 facilitates the installation and maintenance of the components.

[0027] like Figure 1 As shown, at least a portion of the heating element assembly 30 is located within the receiving cavity 11, and the heating element assembly 30 is detachably connected to the housing 10. The heating element assembly 30 is used to bake the aerosol generating matrix, and the detachable heating element assembly 30 seals the battery cell 20 within the receiving cavity 11 to protect the internal battery cell 20 from external contamination.

[0028] like Figures 1-2As shown, the cover 40 covers the housing 10 and seals the opening 12 to confine the heating element assembly 30 and the battery cell 20 within the receiving cavity 11. The cover 40 has a smoke inlet 41, and the heating element assembly 30 has a heating cavity 36; the smoke inlet 41 communicates with the heating cavity 36. The design of the cover 40 protects the internal components while providing good sealing performance to prevent the entry of external contaminants.

[0029] It should be noted that the heating element assembly 30, as an integrated modular structure, can be installed inside the housing 10. The modular design facilitates production and maintenance, and improves the versatility and interchangeability of the heating element assembly 30.

[0030] Furthermore, such as Figures 1-2 As shown, the heating element assembly 30 includes a heating element 31, a housing 32, and a base 33. The heating element 31 is the main heat source for aerosol generation, ensuring stable aerosol generation. The heating element 31 is housed within the housing 32, which provides protection against external physical impacts and contamination, while also aiding in heat dissipation and extending the service life of the heating element 31. A cover 40 is detachably connected to the housing 32 and covers the outer periphery of the housing 32. The cover 40 further protects the heating element 31, preventing foreign objects from entering and ensuring the safety and cleanliness of the aerosol generation process. The heating element 31 is mounted on the base 33, which is detachably connected to the housing 32. The base 33 provides stable support for the heating element 31, ensuring its position remains fixed during operation and preventing performance degradation due to vibration.

[0031] In some examples, such as Figures 1-2 As shown, the base 33 and the housing 32 are connected by screws 34, which ensures the structural stability of the heating element assembly 30 and improves the mechanical strength and durability of the device.

[0032] In one embodiment of this application, such as Figures 1-2As shown, the outer casing 32 has a first threaded hole 321, and the base 33 has a second threaded hole 331 opposite to the first threaded hole 321, which is used to achieve precise alignment, facilitate assembly and disassembly, and improve maintenance efficiency. A portion of the structure forming the wall of the second threaded hole 331 on the base 33 forms an elastic arm 3311. The elastic arm 3311 is suspended and can elastically deform between the direction towards the inner wall of the casing 10 and the direction away from the inner wall of the casing 10. The design of the elastic arm 3311 increases the flexibility of the connection and can absorb and alleviate stress caused by thermal expansion or vibration to a certain extent, improving the reliability of the connection. When the screw 34 is engaged in the second threaded hole 331, the screw 34 abuts against the elastic arm 3311, so that the elastic arm 3311 is engaged with the inner wall of the casing 10. This design ensures that after the screw is fixed, the elastic arm 3311 can tightly engage with the inner wall of the casing 10, providing additional fixing and enhancing the stability of the connection; when the screw 34 is not engaged in the second threaded hole 331, the elastic arm 3311 is separated from the inner wall of the casing 10. This design allows the elastic arm 3311 to be separated when the screw is not inserted, facilitating the insertion and positioning of the base 33, simplifying the assembly process and preventing damage to the elastic arm during assembly.

[0033] As an example, such as Figures 1-2 As shown, at least a portion of the inner peripheral wall of the cover 40 and at least a portion of the outer peripheral wall of the outer shell 32 are connected by friction fit, which simplifies the connection structure, reduces the number of parts, and facilitates the opening of the cover 40.

[0034] As an example, such as Figures 1-2 As shown, the housing 32 is provided with a relief groove 322, and the screw 34 is located in the relief groove 322. The relief groove 322 extends along the axial direction of the screw 34. This design avoids the scratches or damage that may be caused by the screw 34 protruding, and improves the safety of use.

[0035] As an example, such as Figures 1-2 As shown, there are multiple screws 34, which are spaced apart along the circumferential direction of the housing 10. This design evenly distributes the connection pressure, improves the stability of the connection and the overall strength of the housing.

[0036] In one embodiment of this application, such as Figure 1 As shown, the base 33 is provided with a first step portion 35, and the inner peripheral wall of the housing 10 has a second step portion 13 that cooperates with the first step portion 35. The second step portion 13 stops and limits the base 33. This design precisely limits the position of the base 33, prevents it from shifting during use, and ensures the alignment and stability of the components.

[0037] As an example, such as Figure 1As shown, the base 33 is equipped with an adapter circuit board 332 and a main board 333. The battery cell 20 is connected to the main board 333, and the heating element assembly 30 is electrically connected to the main board 333 through the adapter circuit board 332. This design optimizes the circuit layout, reduces circuit interference, and improves the reliability and safety of the circuit.

[0038] As an example, such as Figure 1 As shown, the cover 40 and the housing 10 are detachably connected by a snap or magnetic attraction. This design provides a convenient way to disassemble, making it easy for users to replace the battery or clean the inside, while maintaining good sealing performance and appearance.

[0039] It should be noted that the preferred embodiments of this application are given in the specification and accompanying drawings, but are not limited to the embodiments described in this specification. Furthermore, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
