[0027] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0028] See also Figures 1 to 3 The aerosol generating device 100 of the embodiment of the present application includes a main body component 10 and a cleaning cover 20, and the cleaning cover 20 is detachably connected to the end of the main body component 10. The main body component 10 includes a shell 11 and an end cover 12. The interior of the shell 11 has a receiving cavity 111. The receiving cavity 111 is configured to receive at least part of the aerosol generating product 200, and to receive other components used to heat the aerosol generating product 200, such as a heating component, a power supply component, a circuit board control component, etc. It can be understood that during the process of heating the aerosol generating product 200 to generate aerosol, oil stains or adhered residues will be formed in the receiving cavity 111, so the receiving cavity 111 needs to be cleaned regularly. The end cover 12 is provided at the end of the shell 11. The end cover 12 is provided with a first receiving cavity 121. The bottom wall 1211 of the first receiving cavity 121 is provided with an opening 122 connected to the receiving cavity 111. The opening 122 is configured to allow a cleaning tool to enter the receiving cavity 111 to clean the receiving cavity 111. Please refer to Figures 3 to 5The cleaning cover 20 is detachably disposed within the first accommodating cavity 121. The first accommodating cavity 121 is provided with a first protruding portion 123, and the cleaning cover 20 is provided with a second protruding portion 21. When the cleaning cover 20 rotates relative to the end cover 12, the first protruding portion 123 abuts against the second protruding portion 21, so that at least a portion of the cleaning cover 20 is pushed out of the first accommodating cavity 121 relative to the end cover 12, thereby facilitating separation of the cleaning cover 20 from the end cover 12 to expose the opening 122. With the above structure, the cleaning cover 20 can be at least partially pushed out of the first accommodating cavity 121 during rotation, thereby ensuring that the cleaning cover 20 can be opened smoothly and reducing the difficulty of opening the cleaning cover 20, thereby improving the cleaning efficiency of the aerosol generating device 100.

[0029] It can be understood that the first lifting portion 123 and the second lifting portion 21 include but are not limited to a threaded structure, a boss and slide groove structure, a snap-fit ​​structure, etc., and it is only necessary to ensure that the cleaning cover 20 rotates in a spiral motion relative to the end cover 12, thereby ensuring that at least a portion of the cleaning cover 20 is pushed out of the first cavity 121.

[0030] In some embodiments, see Figure 4 and Figure 5 The side wall of the first cavity 121 is provided with a first protrusion 124, which constitutes the first protrusion 123 on the end cover 12. The side wall of the cleaning cover 20 is provided with a second protrusion 22, which constitutes the second protrusion 21 of the cleaning cover 20. When the cleaning cover 20 moves relative to the end cover 12, the first protrusion 124 abuts against the second protrusion 22 and slides relative to each other. The first protrusion 124 guides the second protrusion 22, thereby allowing the cleaning cover 20 to move in the axial direction.

[0031] As an embodiment, the first protrusion 124 is provided with a first inclined surface 1241, and the second protrusion 22 is provided with a second inclined surface 221. The first inclined surface 1241 and the second inclined surface 221 are mutually connected, so that at least a portion of the cleaning cover 20 is pushed out of the first cavity 121 relative to the end cover 12. Specifically, the first inclined surface 1241 extends obliquely from the bottom wall 1211 of the first cavity 121 toward the opening of the first cavity 121. Through such a structure, on the one hand, the first inclined surface 1241 can guide the second inclined surface 221 in the axial direction. On the other hand, the abutment between the first inclined surface 1241 and the second inclined surface 221 can ensure smooth rotation of the cleaning cover 20 and the end cover 12, thereby avoiding the occurrence of jamming.

[0032] In some embodiments, see Figure 5 and Figure 6The end cover 12 is provided with an extension portion 125, on which a first locking portion 1251 is provided. The second protrusion 21 is provided with a second locking portion 222, which is used to cooperate with the first locking portion 1251 to achieve locking or unlocking of the cleaning cover 20 relative to the end cover 12. When the cleaning cover 20 is disposed in the first cavity 121 and the first locking portion 1251 is connected to the second locking portion 222, the cleaning cover 20 is locked relative to the end cover 12. When the cleaning cover 20 is rotated relative to the end cover 12 so that the first locking portion 1251 and the second locking portion 222 are separated, the cleaning cover 20 is unlocked relative to the end cover 12. Then, under the abutment of the first protrusion 124 and the second protrusion 22, at least a portion of the cleaning cover 20 is pushed out of the first cavity 121. By providing the extension portion 125 on the side wall of the first cavity 121, it is helpful to provide the first locking portion 1251 and the second lifting portion 21 to cooperate and connect, so as to achieve the locking or unlocking of the cleaning cover 20 relative to the end cover 12. In addition, a space is formed between the extension portion 125 and the bottom wall 1211 of the first cavity 121, which is used to accommodate the second lifting portion 21 on the cleaning cover 20. This can reduce the space occupied by the cleaning cover 20 and make the layout and assembly more reasonable. It is understandable that the extension portion 125 can be connected to the first lifting portion 123 in the circumferential direction, which can facilitate the manufacture of the extension portion 125 and the first locking portion 1251 and enhance the structural strength of the first locking portion 1251.

[0033] In some embodiments, see Figure 6 The first locking portion 1251 is arranged on the side of the extension portion 125 facing the bottom wall 1211 of the first cavity 121, and the second locking portion 222 is arranged on the side of the second protruding portion 21 away from the bottom wall 1211 of the first cavity 121. When the cleaning cover 20 is arranged in the first cavity 121, the first locking portion 1251 faces the second locking portion 222 on the extension portion 125, and the second locking portion 222 faces the first locking portion 1251 on the second protruding portion 21. The first locking portion 1251 includes one of a snap-fit ​​portion and a snap-fit ​​groove, and the second locking portion 222 includes the other of the snap-fit ​​portion and the snap-fit ​​groove. The first locking portion 1251 and the second locking portion 222 are connected by the snap-fit ​​portion and the snap-fit ​​groove. Through the above structure, the first locking portion 1251 and the second locking portion 222 can be connected by snapping, thereby enhancing the firmness of the connection between the cleaning cover 20 and the end cover 12.

[0034] In some embodiments, see Figure 6 and Figure 7Along the axial direction of the first cavity 121, a first through-hole 126 is defined on the bottom wall 1211 of the first cavity 121, corresponding to the extension 125. When the engaging portion and the engaging groove are unlocked relative to each other, the second protrusion 22 can at least partially penetrate the first through-hole 126, thereby enabling the engaging portion to be smoothly removed from the engaging groove, thereby unlocking the cleaning cover 20. Of course, during the locking process between the engaging portion and the engaging groove, the second protrusion 22 can at least partially penetrate the first through-hole 126. When the engaging portion slides on the extension 125 until the engaging portion engages with the engaging groove, the cleaning cover 20 is locked.

[0035] In some embodiments, there are multiple first protrusions 124, and avoidance grooves 127 are formed between adjacent first protrusions 124. The second protrusions 22 can pass through the avoidance grooves 127, so that the cleaning cover 20 can smoothly enter the first cavity 121, and the first locking portion 1251 and the second locking portion 222 are locked and connected by rotation. There are multiple second protrusions 22, and the multiple first protrusions 124 are opposite each other end to end to form multiple avoidance grooves 127, and the second protrusions 22 can pass through the corresponding avoidance grooves 127.

[0036] In some embodiments, see Figure 5 and Figure 7 The circumferential outer wall of the cleaning cover 20 is provided with a circumferential groove, and the cleaning cover 20 also includes a sealing member 23, which is sleeved in the groove and partially protrudes from the groove. When the cleaning cover 20 is covered in the first cavity 121, the sealing member 23 abuts against the inner wall of the first cavity 121, thereby sealing the gap between the cleaning cover 20 and the end cover 12. On the one hand, this can prevent external dust and impurities from entering the receiving cavity 111 and causing internal contamination of the aerosol generating device 100. On the other hand, the sealing member 23 can keep the cleaning cover 20 stably in the first cavity 121, thereby preventing the cleaning cover 20 from shaking relative to the end cover 12 during use or transportation and causing abnormal noise.

[0037] In some embodiments, see Figure 7When the cleaning cover 20 is disposed in the first cavity 121, the cleaning cover 20 is flush or approximately flush with the end cover 12, which can prevent the cleaning cover 20 from protruding from the end cover 12 and affecting the aesthetics of the aerosol generating device 100. At this time, a plug-in slot 24 can be provided at the end of the cleaning cover 20 away from the first cavity 121. The plug-in slot 24 is used for an external object to drive the cleaning cover 20 to rotate relative to the end cover 12, thereby achieving the locking or unlocking of the cleaning cover 20 to the end cover 12. By providing the plug-in slot 24 on the end of the cleaning cover 20, the difficulty of rotating the cleaning cover 20 can be reduced. It is worth noting that the above-mentioned external objects include but are not limited to screwdrivers, adapted brush assemblies 30, and even the user's fingers, etc., and it is sufficient as long as they can achieve the driving of the cleaning cover 20 to rotate under the action of the plug-in slot 24.

[0038] In some embodiments, see Figure 1 and Figure 8 The aerosol generating device 100 also includes a brush assembly 30, which includes a gripping portion 31 and a brush 32. The brush 32 is connected to one end of the gripping portion 31. The gripping portion 31 is used for the user to grip, thereby facilitating the operation of the brush 32 for cleaning. Furthermore, the gripping portion 31 is used to connect with the cleaning cover 20, thereby driving the cleaning cover 20 to rotate relative to the end cover 12. Specifically, the end of the gripping portion 31 facing away from the brush is provided with a plug-in portion 311. The plug-in portion 311 is adapted to fit with the plug-in slot 24 on the cleaning cover 20. When the plug-in portion 311 is plugged into the plug-in slot 24, the cleaning cover 20 can be rotated relative to the end cover 12 by rotating the gripping portion 31.

[0039] In some embodiments, see Figure 8 A first magnetic component 25 is provided inside the cleaning cover 20, and a second magnetic component 33 is provided inside the holding portion 31. The first magnetic component 25 and the second magnetic component 33 have opposite magnetic properties on opposite sides, so that the first magnetic component 25 can be attracted to the second magnetic component 33, thereby adsorbing the cleaning cover 20 on the holding portion 31, so that the cleaning cover 20 can be placed in the first cavity 121 or pulled out from the first cavity 121.

[0040] The above description is merely an embodiment of the present application and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
