[0037] In some embodiments, the housing 10 may include a main body 11 and a cover 12; the main body 11 is generally columnar and hollow inside. A heating cavity 110 is formed inside the housing 10, which is used to contain and heat the aerosol generation matrix. In some embodiments, the heating cavity 110 may be formed directly in the main body 11. In other embodiments, the heating cavity 110 may also be formed in a heating assembly located in the main body 11. In some embodiments, the main body 11 has an opening 111 that communicates with the heating cavity 110. The opening 111 can be fitted with the cover 12. The cover 12 can cover the opening 111.

[0038] In some embodiments, a window 112 may be provided on one side of the main body 11. The window 112 may communicate with the heating chamber 110 and may be used to place the aerosol generation substrate into the heating chamber 110 for easy replacement of the aerosol generation substrate.

In some embodiments, the insertion portion 1210 may be interference-fitted with the main body portion 11. A first mounting groove 1211 may be provided on the side of the cover body 121 facing away from the heating cavity 110, which can accommodate a magnetic attractor. Of course, it is understood that in some other embodiments, the first mounting groove 1211 may be omitted.

[0040] In some other embodiments, the cover portion 12 is not limited to being detachably connected to the main body portion 11. In some embodiments, the cover portion 12 and the main body portion 11 can be connected to form a fixed and non-detachable integral structure. For example, the cover portion 12 and the main body portion 11 can be fixed by adhesive or ultrasonic welding, and the two cannot be separated after fixing. In some other embodiments, the cover portion 12 and the main body portion 11 can also be an integrally formed structure.

[0041] In some embodiments, the housing 10 is provided with an air passage structure 122. Specifically, the air passage structure 122 may be disposed on the side of the cover body 121 opposite to the heating chamber 110. The air passage structure 122 may protrude from the cover body 121. In some embodiments, the air passage structure 122 may be a columnar structure with both ends extending through it, and at least a partial airflow channel may be formed on its inner side. The air passage structure 122 may communicate with the heating chamber 110. In some embodiments, the air passage structure 122 may be configured to be detachably connected to and communicate with one of the suction nozzle 20 and the filter nozzle 60, thereby facilitating the replacement of the suction nozzle 20 with the filter nozzle 60 or vice versa, thus meeting user needs and improving the user experience.

[0042] The connection state between the airway structure 122 and the nozzle 20 can be as follows: Figure 1 and Figure 2 As shown, the connection state between the airway structure 122 and the filter 60 can be as follows: Figure 8 and Figure 9 As shown. When the airway structure 122 is connected to the nozzle 20, the aerosol generated by the heating chamber 110 is drawn out through the nozzle 20, and the user can directly use the nozzle 20 to draw in the aerosol. The nozzle 20 improves the overall aesthetics of the aerosol generating device 100. When the airway structure 122 is connected to the filter 60, the aerosol generated by the heating chamber 110 can be filtered by the filter 60 and then output.

[0043] like Figure 2 , Figure 5 and Figure 6 As shown, in some embodiments, the airway structure 122 can be partially inserted into the nozzle 20 and connected to the nozzle 20. In some embodiments, the airway structure 122 is provided with a receiving groove 1221, which can be used to receive the filter structure 30 or part of the filter 60.

[0044] In some embodiments, the air passage structure 122 may be integrally formed with the cover body 121. Specifically, the air passage structure 122 and the cover body 121 may be integrally formed by injection molding or casting. In other embodiments, the air passage structure 122 and the cover body 121 may also be separate structures, and the two may be connected and fixed by a fixing structure, such as a snap-fit ​​structure or an adhesive structure.

[0045] In some embodiments, the nozzle 20 can be used for manual aspiration of aerosols, and its appearance, together with that of the housing 10, forms the overall appearance of the aerosol generating device 100. The nozzle 20 can be detachably assembled with the housing 10. In some embodiments, the nozzle 20 housing includes a sleeve portion 21 and a suction portion 22 protruding from one end of the sleeve portion 21. The sleeve portion 21 is detachably fitted onto the housing 10, specifically, it can be fitted onto the cover body 121 and the airway structure 122. The cross-sectional shape of the sleeve portion 21 can be adapted to the cross-sectional shape of the main body portion 11. In some embodiments, the cross-sectional shape of the sleeve portion 21 can be elliptical, rectangular, etc. A second mounting groove 211 can be provided on the side of the sleeve portion 21 facing the cover body 121. The second mounting groove 211 can be provided one-to-one with the first mounting groove 1211, and the two can be arranged opposite each other, which can be used for magnetic attachment. The suction portion 22 is provided at one end of the sleeve portion 21, and it can be integrally structured with the sleeve portion 21. The suction section 22 is configured to pass through the sleeve section 21 and can communicate with the airway structure 122 to form at least a partial airflow channel. The suction section 22 can be designed with a flat nozzle, making the aerosol generating device 100 more aesthetically pleasing. One end of the suction section 22 is provided with a suction port 220, which can be used to output aerosol.

[0046] In some embodiments, a groove 23 may be provided on the side of the sleeve portion 21 facing the housing 10. The groove 23 may be coaxially arranged with and communicate with the suction portion 22. When the nozzle 20 is connected to the airway structure 122, the airway structure 122 may be at least partially inserted into the groove 23. In some embodiments, the airway structure 122 may be press-fitted with the groove 23. Of course, it is understood that in some other embodiments, the airway structure 122 may also be clearance-fitted with the groove 23.

[0047] In some embodiments, a sealing structure 30 may be provided between the nozzle 20 and the airway structure 122. This sealing structure 30 seals the gap between the nozzle 20 and the airway structure 122, preventing external air from entering the groove 23 during suction, thereby preventing the user from suctioning excessive amounts of air entering from the outside. In some embodiments, the sealing structure 30 may be a sealing ring, which may be fitted onto the airway structure 122 and tightly abut against the inner wall of the groove 23. The airway structure 122 has a limiting groove 1222 that mates with the sealing structure 30. The limiting groove 1222 may be an annular groove. In other embodiments, the sealing structure 30 may be a sealing sleeve, which may be fitted onto the outer periphery of the airway structure 122 and interference-fitted with both the airway structure 122 and the groove 23.

[0048] In some embodiments, when the airway structure 122 is connected to the nozzle 20, a filter structure 40 is detachably provided in the airway structure 122. The aerosol generated by the heating chamber 110 can be filtered by the filter structure 40 before being output through the nozzle 20. The filter structure 40 is housed in the receiving groove 1221 and can communicate with the nozzle 20. It can filter the aerosol when the nozzle 20 is used for suction. In some embodiments, the filter structure 40 can be a porous structure, which can include sponge or foam material, ceramic-based or graphite-based material in the form of fiber or sintered powder, foam metal or plastic material, fiber material (e.g., made of virgin fiber or pressed fiber (e.g., cellulose acetate fiber, polyester fiber, bonded polyolefin fiber, polyethylene fiber, polyester fiber or polypropylene fiber, nylon fiber)) or ceramic.

[0049] In some embodiments, the filter structure 40 may be generally columnar, being a hollow structure with both ends open. The filter structure 40 may have a clearance fit or a clearanceless fit with the receiving groove 1221. In some embodiments, the height of the filter structure 40 may be less than or equal to the depth of the receiving groove 1221. Of course, it is understood that in some other embodiments, the height of the filter structure 40 may also be greater than the depth of the receiving groove 1221, and the portion of the filter structure 40 protruding from the receiving groove 1221 may be embedded in the groove 23.

[0050] By detachably housing the filter structure 40 within the receiving groove 1221, replacement of the filter structure 40 is facilitated. When the user uses the nozzle 20, the aerosol generated in the heating chamber 110 during heating is carried upwards by suction, filtered through the hollow filter structure 40, and then enters the oral cavity through the air passage of the nozzle 20. When the filter structure 40 reaches the end of its service life, the nozzle 20 can be disassembled, a new filter structure 40 replaced, and the nozzle 20 reinstalled for continued suction.

[0051] In some embodiments, the aerosol generating device 100 further includes a connecting assembly 50 for detachably connecting the nozzle 20 and the housing 10, the connecting assembly 50 being used to connect and fix the housing 10 to the nozzle 20. Of course, it is understood that in some other embodiments, the connecting assembly 50 may be omitted. In some embodiments, the connecting assembly 50 may include at least one of a magnetic component, a snap-fit ​​component, and an adhesive component.

[0052] For example Figure 3As shown, specifically, the connecting component 50 may include at least one set of magnetic suction components. There may be two sets of magnetic suction components, which are spaced apart on opposite sides of the air passage structure 122. In some other embodiments, there may be only one set of magnetic suction components or more than two sets. The connecting component 50 may include a first magnetic suction member 51 and a second magnetic suction member 52. The first magnetic suction member 51 may be disposed on the cover portion 12, and the second magnetic suction member 52 may be disposed on the suction nozzle 20. Specifically, the first magnetic suction member 51 may be installed in the first mounting groove 1211 and fastened therein by in-mold injection molding or dispensing. The second magnetic suction member 52 may be installed in the second mounting groove 211 and fastened therein by in-mold injection molding or dispensing. By attracting the first magnetic suction member 51 and the second magnetic suction member 52, the suction nozzle 20 can be connected and fixed to the cover portion 12. When disassembling the suction nozzle 20, it can be pulled away from the main body 11 to separate the first magnetic component 51 from the second magnetic component 52. Both the first magnetic component 51 and the second magnetic component 52 can be magnets. By selecting appropriate magnets, easy disassembly can be ensured, thus achieving quick disassembly and assembly, and making it easy to switch between two usage modes.

[0053] like Figures 7 to 9 As shown, when it is necessary to replace the filter 60, the suction nozzle 20 can be removed, and then the filter 60 can be connected to the airway structure 122. The filter 60 can be partially nested within the airway structure 122. In some embodiments, the filter 60 can be partially embedded in the receiving groove 1221. Of course, it is understood that in some other embodiments, the filter 60 can also be fitted onto a portion of the outer periphery of the airway structure 122.

[0054] In some embodiments, the filter tip 60 may be interference-fitted with the receiving groove 1221 or with the air passage structure 122, thereby achieving a seal between the two. Of course, it is understood that a seal may also be provided between the filter tip 60 and the inner wall of the receiving groove 1221, or between the filter tip 60 and the outer wall of the air passage structure 122. This seal may be removable.

[0055] In some embodiments, the filter tip 60 may be generally cylindrical, protruding from the air passage structure 122, with a height greater than the depth of the receiving groove 1221, and may partially protrude from the receiving groove 1221 for user suction. In some embodiments, the filter tip 60 may be cylindrical. In some embodiments, the filter tip 60 may be through-hole at both ends. In other embodiments, the filter tip 60 may also be a solid structure.

[0056] In some embodiments, the filter 60 may be a porous structure, which may include sponge or foam material, ceramic-based or graphite-based material in the form of fiber or sintered powder, foam metal or plastic material, fibrous material (e.g. made of virgin or pressed fiber (e.g. cellulose acetate fiber, polyester fiber, bonded polyolefin fiber, polyethylene fiber, polyester fiber or polypropylene fiber, nylon fiber)) or ceramic.

[0057] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
