Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment, and do not mean that the sequence is necessary, unless otherwise stated that a certain sequence must be followed.

[0044] The serial numbers of components in this document, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequence or technical meaning. Unless otherwise specified, "connection", "coupling" in this application includes direct connection, indirect connection and contact connection (coupling) and the like.

[0045] In one embodiment, the aerosol-generating device includes a housing, an atomization assembly, and a sliding cover assembly. The atomization assembly includes a heating element for heating an aerosol-generating substrate.

[0046] Please refer to Figures 1 to 4 The sliding cover assembly includes a cover seat 1, a sliding cover 2, and a guide structure 3. The cover seat 1 has a cover seat hole 11 for communication with the inside of the aerosol-generating device. The sliding cover 2 is slidingly assembled on the cover seat 1. In the sliding stroke of the sliding cover 2, the sliding cover 2 has a closed position covering the cover seat hole 11 and an open position exposing the cover seat hole 11, and also has an intermediate position between the closed position and the open position.

[0047] The guide structure 3 is used to guide the sliding of the sliding cover 2 relative to the cover seat 1. The guide structure 3 is arranged on the cover seat 1. The guide structure 3 comprises a pressing portion 31. The pressing portion 31 is used to apply pressure to the sliding cover 2 at least when the sliding cover 2 is in the middle position. The pressure is used to press the sliding cover 2 and the cover seat 1 in the extension direction of the cover seat hole 11.

[0048] Since the guide structure 3 of the sliding cover assembly is arranged on the cover seat 1, the guide structure 3 comprises the pressing portion 31. The pressing portion 31 applies pressure to the sliding cover 2 when the sliding cover 2 is in the middle position. The pressure is used to press the sliding cover 2 and the cover seat 1 in the extension direction of the cover seat hole 11. Compared with the current sliding cover 2 and the cover seat always being gap-fitted, the sliding cover 2 needs to overcome greater frictional force when sliding from the closed position to the middle position in the present application. The sliding cover 2 also needs to overcome greater frictional force when sliding from the open position to the middle position. In this way, the sliding cover 2 is not easy to shake and is not easy to leave the closed position and the open position. The problem that the sliding cover 2 is easy to leave the target position and causes poor reliability of the sliding cover 2 when sliding in the current sliding cover assembly is improved. In addition, since greater pushing force needs to be applied to move the sliding cover 2 when changing the position, the operation feeling of the sliding cover 2 is also improved.

[0049] It needs to be noted that the middle position in the present application is not limited to a specific position. Any position between the open position and the closed position of the sliding cover is the middle position. The pressing in the present application means that the sliding cover is in contact with the cover seat and that the sliding cover and the cover seat have a certain force therebetween. However, this does not affect the pushing of the sliding cover to slide.

[0050] In one embodiment, the sliding cover 2 slides along a straight line. In one embodiment, the cover seat 1 is part of the shell of the aerosol generating device. In some other embodiments, the cover seat 1 can also be fixed on the shell.

[0051] Regarding the type of the aerosol generating device, in one embodiment, the aerosol generating device is used to heat an aerosol generating stick. The atomization assembly has a plug hole for the aerosol generating stick to be inserted into. The cover seat hole 11 is opposite to the plug hole. The aerosol generating stick passes through the cover seat hole 11 and enters the plug hole. In one embodiment, the sliding cover assembly can also be applied to adjust the air intake amount of the aerosol generating device. At this time, the cover seat hole 11 communicates with the air inlet channel in the aerosol generating device.

[0052] Further, in one embodiment, please refer to Figures 3 to 5 The pressing portion 31 applies force to the sliding cover 2 through elastic deformation. The elastic deformation can apply force to the sliding cover 2 more gently. In addition, the elastic deformation is convenient for assembly and can reduce the assembly difficulty. In some other embodiments, in addition to relying on the elastic deformation, the pressing portion 31 can also rely on the rigid pressing action to apply force to the sliding cover 2.

[0053] Further, regarding the structure of the pressing portion, in one embodiment, please refer to Figures 3 to 5The pressing part 31 comprises a spring arm 311 and a hook 312 at the end of the spring arm 311. The extending direction of the spring arm 311 is consistent with the extending direction of the cover seat hole 11, and the hook 312 hooks on the sliding cover 2 and can slide relative to the sliding cover 2. The pressing part 31 exerts force on the sliding cover 2 through the elastic deformation of the spring arm 311 and the hook 312. The spring arm 311 is more easily deformed, and the hook 312 facilitates the assembly of the sliding cover 2 and the pressing part 31.

[0054] In some other embodiments, the pressing part 31 can also exert force on the sliding cover 2 only through the elastic deformation of the spring arm 311, and the hook 312 is a rigid structure. Of course, in some other embodiments, the pressing part 31 can also exert force on the sliding cover 2 only through the elastic deformation of the hook 312, and the spring arm 311 is a rigid arm.

[0055] In one embodiment, please refer to Figures 3 to 5 The at least one spring arm 311 is a first spring arm 3111, the hook 312 on the first spring arm 3111 is a first hook 3121, the at least one spring arm 311 is a second spring arm 3112, and the hook 312 on the second spring arm 3112 is a second hook 3122. The first hook 3121 is arranged on the side of the first spring arm 3111 away from the second spring arm 3112, and the second hook 3122 is arranged on the side of the second spring arm 3112 away from the first spring arm 3111. The first spring arm 3111 and the second spring arm 3112 are arranged in a spaced manner, and when the first spring arm 3111 and the second spring arm 3112 are deformed, the first hook 3121 and the second hook 3122 move in a direction of approaching each other, and the end of the first spring arm 3111 and the end of the second spring arm 3112 approach each other.

[0056] It should be noted that the first end of the spring arm 311 of the present application is a fixed end, and the end is a free end which can be elastically deformed under the action of external force, and the hook 312 is at the end of the spring arm 311.

[0057] In one embodiment, please refer to Figures 3 to 5 The number of spring arms 311 is two, and the two spring arms 311 are a first spring arm 3111 and a second spring arm 3112. In some other embodiments, according to actual needs, the number of spring arms 311 can also be more than two pairs, and the two spring arms 311 in each pair are a first spring arm 3111 and a second spring arm 3112.

[0058] In order to facilitate processing, in one embodiment, please refer to Figures 3 to 5In the sliding stroke of the sliding cover 2, the first elastic arm 3111 and the second elastic arm 3112 are always symmetrically arranged. Specifically, in one embodiment, the guide structure 3 is symmetrically arranged as a whole, and the symmetric plane of the guide structure 3 is the symmetric plane of the first elastic arm 3111 and the second elastic arm 3112. In some other embodiments, the first elastic arm 3111 and the second elastic arm 3112 can also be asymmetrically arranged, such as that the length of the first elastic arm 3111 is greater than the length of the second elastic arm 3112, or such as that the cross-sectional dimension of the first elastic arm 3111 is not equal to the cross-sectional dimension of the second elastic arm 3112, or such as that the height of the first elastic arm 3111 is different from the height of the second elastic arm 3112.

[0059] In one embodiment, referring to Figures 2 to 7 , the sliding cover 2 has a mating surface 21 in contact with the hook 312, and the mating surface 21 includes an opening mating section 211, a closing mating section 212, and an intermediate section 213. The opening mating section 211, the intermediate section 213, and the closing mating section 212 are arranged in sequence in the moving direction of the sliding cover 2. When the opening mating section 211 is in contact with the hook 312, the sliding cover 2 is in the opening position. When the closing mating section 212 is in contact with the hook 312, the sliding cover 2 is in the closing position. When the intermediate section 213 is disengaged from the hook 312, the sliding cover 2 is in the intermediate position. At least part of the intermediate section 213 protrudes towards the hook 312 relative to the opening mating section 211, and at least part of the intermediate section 213 protrudes towards the hook 312 relative to the closing mating section 212. By making the intermediate section 213 protrude towards the hook 312, a greater force needs to be overcome when the sliding cover 2 is moved away from the opening position or the closing position, thereby improving the reliability of the sliding cover 2.

[0060] In one embodiment, referring to Figure 2 , Figure 4 , Figure 6 and Figure 7 , the intermediate section 213 as a whole protrudes towards the hook 312 relative to the opening mating section 211, and protrudes towards the hook 312 relative to the closing mating section 212.

[0061] In one embodiment, referring to Figure 4 and Figure 5 , since the hook 312 is deformed greatly when hooked on the intermediate section 213, in order to facilitate the installation of the hook 312 and make the sliding of the sliding cover 2 smoother, the intermediate section 213 is a slope surface, and the intermediate section 213 gradually approaches the elastic arm 311 in the direction perpendicular to the moving direction of the sliding cover 2 and away from the hook 312. When the hook 312 is hooked on the intermediate section 213, the hook 312 is in surface contact with the intermediate section 213. In this way, the hook 312 and the intermediate section 213 maintain surface contact, are less likely to be scratched by edges and corners, and the cooperation between the hook 312 and the sliding cover 2 is more stable. Of course, in some other embodiments, the intermediate section 213 can also be a plane parallel to the opening mating section 211.

[0062] To make the sliding of the sliding cover 2 more smooth, in one embodiment, please refer to Figure 2 , Figure 4 , Figure 6 and Figure 7 , the two ends of the middle section 213 have transition sections 214, which make the sliding cover 2 slide smoothly on the closing fitting section 212, the middle section 213 and the opening fitting section 211. In one embodiment, the transition section 214 is a transition slope. In some other embodiments, the transition section 214 can also be a curved surface of smooth transition.

[0063] In one embodiment, please refer to Figures 3 to 5 , the sliding cover 2 includes a pressed section 22, and the pressing section 31 contacts and presses the pressed section 22. The pressed section 22 is suspended on the cover base 1, so that the pressed section 22 is not in contact with the cover base 1 when the pressed section 22 is elastically deformed, thereby reducing the contact area between the cover base 1 and the sliding cover 2. Of course, in some other embodiments, the pressed section 22 can be in contact with the cover base 1, and a part not in contact with the cover base 1 can be provided at other positions of the sliding cover 2 to reduce the contact area. Of course, it is also feasible that the side of the sliding cover 2 facing the cover base 1 is in contact with the cover base 1 as a whole.

[0064] Regarding the form of the guide structure 3, in one embodiment, please refer to Figure 2 and Figure 3 , the guide structure 3 includes a guide 30 fixedly assembled on the cover base 1, and part of the guide 30 extends into the sliding cover 2, and the pressing section 31 is on the guide 30. By adopting the mode of fixedly assembling the guide 30, the processing and installation of the guide structure 3 are facilitated.

[0065] In one embodiment, please refer to Figure 2 and Figure 3 , the guide 30 is fixed on the cover base 1 by means of a screw 4. Specifically, in one embodiment, please refer to Figure 2 and Figure 3 , the cover base 1 has a clamping groove 12, the guide 30 is inserted into the clamping groove 12, the groove bottom of the clamping groove 12 has a fixing hole through which the screw 4 passes, and the screw 4 is screwed into the guide 30 after passing through the fixing hole.

[0066] In one embodiment, please refer to Figure 2 and Figure 3 , the sliding cover 2 has a sliding groove 23, the guide 30 extends into the sliding groove 23 from the groove opening of the sliding groove 23, the groove opening of the sliding groove 23 is provided with an inner convex edge, the pressing section 31 acts on the inner side of the inner convex edge, and the inner convex edge forms the pressed section 22. In one embodiment, please refer to Figure 2and Figure 3 The first hook 3121 and the second hook 3122 are respectively hooked on the two opposite inner convex edges of the sliding groove 23.

[0067] In one embodiment, referring to Figure 3 and Figure 5 The guide 30 is T-shaped, and the guide 30 is provided with a guide groove 301 between the first elastic arm 3111 and the second elastic arm 3112.

[0068] In order to facilitate the installation of the guide 30, in one embodiment, referring to Figure 2 and Figure 3 The cover 2 includes a cover body 24 and a cover cap 25, the cover body 24 and the cover cap 25 are fixedly assembled together and surround the sliding groove 23, the groove bottom of the sliding groove 23 is on the cover cap 25, and the groove opening is on the cover body 24. The groove opening of the sliding groove 23 faces the cover base 1. When installing the guide 30, the guide 30 and the cover body 24 can be installed together first, and then the cover cap 25 is covered, so that the installation efficiency is higher. In one embodiment, referring to Figure 2 and Figure 3 The cover body 24 and the cover cap 25 are fixedly assembled together by clamping.

[0069] In one embodiment, referring to Figures 2 to 7 During the sliding stroke of the cover 2, the pressing part 31 continuously applies pressure to the cover 2. The pressure applied by the pressing part 31 to the cover 2 at the middle position is greater than the pressure applied by the pressing part 31 to the cover 2 at the open position, and is greater than the pressure applied by the pressing part 31 to the cover 2 at the closed position. In one embodiment, the pressing part 31 does not apply pressure to the cover 2 when the cover 2 is at the closed position or the open position, and the pressing part 31 only applies pressure to the cover 2 at the middle position.
