[0026] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various implementations, and the operational steps involved in each embodiment may be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a particular embodiment and do not imply a required composition and / or sequence.

[0027] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0028] An embodiment of the present application discloses a dust cover assembly, which is used in an aerosol generating device to provide an aerosol outlet 12 for inserting an aerosol product into a receiving cavity. It is also used to avoid the aerosol outlet 12 when the aerosol generating device is in a working state, and to block the aerosol outlet 12 when the aerosol generating device is not in a working state, so as to prevent foreign matter or dust from entering the receiving cavity from the aerosol outlet 12 and affecting the normal operation of the aerosol generating device.

[0029] The dust cover assembly of the embodiment of this application, please refer to Figures 1 to 4 , including a fixed cover 1, a fixing part 2 and a dust-proof structure 3. The fixed cover 1 is used to be installed on the device body of the aerosol generating device. The fixed cover 1 has an aerosol outlet 12 for communicating with the accommodating cavity of the device body. The aerosol product can be inserted into the accommodating cavity from the aerosol outlet 12 to realize the installation and positioning of the aerosol product in the accommodating cavity. The aerosol outlet 12 can also be used to discharge the aerosol generated after the aerosol product is heated.

[0030] The fixing member 2 is mounted on the fixing cover 1 and can be fixedly connected to the fixing cover 1. The fixing member 2 is located beside the aerosol outlet 12 and has a crimping portion 22 spaced apart from the fixing cover 1 in the direction of the aerosol outlet 12. The dustproof structure 3 includes a sliding cover 31, which has a slide rail 313 extending in a first direction. The slide rail 313 is located between the fixing cover 1 and the crimping portion 22 in the direction of the aerosol outlet 12. The sliding cover 31 can slide back and forth relative to the fixing member 2 along the direction in which the slide rail 313 extends, that is, along the first direction. During the sliding process, the sliding cover 31 has a first position in which the dustproof structure 3 blocks the aerosol outlet 12, and a second position in which the aerosol outlet 12 is avoided. The sliding cover 31 can slide back and forth between the first position and the second position along the first direction relative to the fixing member 2 to meet the needs of the aerosol generating device when in use and when not in use. In this way, by installing the fixing part 2 on the fixing cover 1 and providing the crimping portion 22 on the fixing part 2, the sliding cover 31 can be switched between the first position and the second position relative to the crimping portion 22 in the extension direction of the slide rail 313. There is no need to groove the fixing cover 1, which can prevent dust or foreign matter from entering the device body through the groove on the fixing cover 1 and affecting the normal operation of the aerosol generating device, which helps to ensure the normal operation of the aerosol generating device.

[0031] In addition, in the dust cover assembly of the embodiment of the present application, the slide rail 313 and the fixed cover 1 are arranged at intervals upward in the direction of the aerosol outlet 12. Under the pressure of the crimping part 22, the slide rail 313 can produce elastic deformation in the direction of the aerosol outlet 12 to meet the elastic pressure of the slide rail 313 and the crimping part 22 in the direction of the aerosol outlet 12. In this way, the crimping part 22 can press the slide cover 31 onto the fixed cover 1 in the direction of the aerosol outlet 12, which can reduce the gap between the dustproof structure 3 and the fixed cover 1, realize the pre-tightening of the dustproof structure 3 and the fixed cover 1, and avoid larger foreign matter from entering the device body through the gap between the dustproof structure 3 and the fixed cover 1, thereby reducing dust or foreign matter from entering the device body through the gap between the dustproof structure 3 and the fixed cover 1, and also helping to ensure the normal operation of the aerosol generating device.

[0032] In one embodiment, please refer to Figure 2 and Figure 3The fixing member 2 includes a fixing portion 21 connected to the fixing cover 1. The fixing portion 21 extends upward in the direction of the aerosol outlet 12. The fixing cover 1 has a notch facing the mounting slot 11 in the same direction as the aerosol outlet 12. The fixing portion 21 is located within the mounting slot 11 and can be fixed within the mounting slot 11 by riveting or fastener connection. For example, a through-hole can be provided on the bottom wall of the mounting slot 11, through which a screw passes and connects to the fixing portion 21. The bottom wall of the mounting slot 11 protrudes toward the device body relative to the position of the fixing cover 1 provided with the aerosol outlet 12. That is, the bottom wall of the mounting slot 11 protrudes upward in the direction of the aerosol outlet 12 and away from the sliding cover 31, thereby increasing the depth of the mounting slot 11 and the length of the connection between the fixing portion 21 and the screw. This increases the contact area between the fixing portion 21 and the wall of the mounting slot 11, and increases the contact area between the fixing portion 21 and the screw, thereby helping to increase the connection strength between the fixing portion 21 and the fixing cover 1.

[0033] Of course, in an embodiment where the length of the fixing portion 21 is shorter, the installation groove 11 can be eliminated on the fixing cover 1, and a through hole can be directly provided on the fixing cover 1, and a screw passes through the through hole and is connected to the fixing portion 21 to achieve a fixed connection between the fixing member 2 and the fixing cover 1.

[0034] Please continue to refer to Figure 2 and Figure 3 The crimping portion 22 on the fixing member 2 is connected to the fixing portion 21, and the fixing portion 21 protrudes from the fixing cover 1 toward the sliding cover 31. The crimping portion 22 is connected to the end of the fixing portion 21 in the direction of the aerosol outlet 12. The crimping portion 22 faces the second direction, and the second direction, the first direction, and the direction of the aerosol outlet 12 are perpendicular to each other.

[0035] In one embodiment, please continue to refer to Figure 2 and Figure 4 The number of the crimping portions 22 on the fixing member 2 can be two, both of which face the second direction and face opposite directions. Alternatively, in other embodiments, only one crimping portion 22 can be provided.

[0036] For some examples, please refer to Figures 2 to 4 For the sliding cover 31, the sliding cover 31 has a frame 311, and the frame 311 can be a rectangular frame. The frame 311 has two first frame edges 3111 extending in a first direction, and two second frame edges 3112 extending in a second direction. The first frame edges 3111 and the second frame edges 3112 are arranged alternately and connected end to end. The frame 311 has a hollow structure, and the sliding rail 313 is located in the hollow structure of the frame 311 and is connected to the frame 311.

[0037] In one embodiment, the two ends of the slide rail 313 in its extension direction are respectively connected to the second frame edge 3112, and the slide rail 313 and the first frame edge 3111 are spaced apart in the second direction, and the slide rail 313 and the fixed cover 1 are spaced apart upward toward the aerosol outlet 12, so that the slide rail 313 forms a simply supported beam structure with both ends fixed on the frame 311, and the slide rail 313 is located between the crimping portion 22 and the fixed cover 1. Under the pressure of the crimping portion 22, the slide rail 313 will elastically deform toward the fixed cover 1, so that the crimping portion 22 and the slide rail 313 are elastically pressed upward toward the aerosol outlet 12, and the slide cover 31 can be pressed tightly against the fixed cover 1 to reduce the gap between the dustproof structure 3 and the fixed cover 1.

[0038] In another embodiment, one end of the sliding rail 313 in its extension direction is connected to the second frame edge 3112, and the other end is suspended. The sliding rail 313 and the first frame edge 3111 are spaced apart in the second direction, and the sliding rail 313 and the fixed cover 1 are spaced apart upward toward the aerosol outlet 12. The sliding rail 313 forms a cantilever beam structure. The sliding rail 313 is located between the crimping portion 22 and the fixed cover 1. Under the pressure of the crimping portion 22, the sliding rail 313 will elastically deform toward the fixed cover 1. The crimping portion 22 can press the sliding cover 31 onto the fixed cover 1 to reduce the gap between the dustproof structure 3 and the fixed cover 1.

[0039] In one embodiment, the frame 311 has a lower surface facing the fixed cover 1, and the lower surface of the frame 311 is in contact with the fixed cover 1. The slide rail 313 and the lower surface of the frame 311 are spaced apart from each other in the direction of the aerosol outlet 12 to provide a deformation margin for the elastic deformation of the slide rail 313 toward the fixed cover 1. In another embodiment, please refer to Figure 4 The slide rail 313 is integrally formed with the frame 311, and the side surface of the slide rail 313 facing the fixed cover 1 can be coplanar with the lower surface of the frame 311 to facilitate the processing and manufacturing of the slide rail 313. Protrusions can also be provided on the two first frame edges 3111 on the lower surface of the frame 311, and the frame 311 contacts the fixed cover 1 through the protrusions. In this way, the slide rail 313 and the fixed cover 1 are spaced apart upward in the direction of the aerosol outlet 12, so as to provide a deformation margin for the elastic deformation of the slide rail 313 toward the fixed cover 1, thereby ensuring that the slide rail 313 can be elastically deformed toward the fixed cover 1.

[0040] In some embodiments, the sliding cover 31 has a groove 312, the groove 312 has a groove opening facing the same direction as the aerosol outlet 12, the crimping portion 22 is located in the groove 312, and the slide rail 313 is located on the bottom wall of the groove 312. This can reduce the size of the crimping portion 22 protruding from the sliding cover 31 in the direction of the aerosol outlet 12, thereby realizing a miniaturized design of the entire dust cover assembly.

[0041] Specifically, please refer to Figures 2 to 4The frame 311 has an upper surface facing away from the fixed cover 1, and the slide rail 313 also has a side facing away from the fixed cover 1. The distance between the side of the slide rail 313 facing away from the fixed cover 1 and the fixed cover 1 is smaller than the distance between the upper surface of the frame 311 and the fixed cover 1. In this way, a sinking groove 312 is formed in the frame 311, and the side of the slide rail 313 facing away from the fixed cover 1 can form the bottom wall of the sinking groove 312, which can be equivalent to the slide rail 313 being arranged on the bottom wall of the sinking groove 312. The dimension of the crimping portion 22 in the direction of the aerosol outlet 12 can be arranged smaller than the groove depth of the sinking groove 312, so that the crimping portion 22 can be avoided from protruding from the upper surface of the frame 311, thereby helping to reduce the dimension of the entire dust cover assembly in the direction of the aerosol outlet 12.

[0042] Of course, in other embodiments, if the sinking groove 312 is not provided on the sliding cover 31 , it is also possible to make the side of the sliding rail 313 facing away from the fixed cover 1 flush with the upper surface of the frame 311 .

[0043] In one embodiment, please refer to Figure 2 and Figure 4 The cam 314 is provided with two slide rails 313, and the two slide rails 313 are arranged at intervals in the second direction. The two slide rails 313 are arranged on both sides of the fixed portion 21 of the fixing member 2 in the second direction. The two crimping portions 22 correspond to the two slide rails 313 one by one. One of the crimping portions 22 faces one slide rail 313 in the second direction and elastically presses against the slide rail 313 in the upward direction of the aerosol outlet 12. The other crimping portion 22 faces the other slide rail 313 in the second direction and elastically presses against the other slide rail 313 in the upward direction of the aerosol outlet 12. In this way, both sides of the fixing member 2 in the second direction are elastically pressed against the sliding cover 31 in the upward direction of the aerosol outlet 12, which can balance the pressure of the fixing member 2 on the sliding cover 31 on both sides in the second direction, evenly distribute the gap between the sliding cover 31 and the fixing cover 1, and balance the pre-tightening force between the sliding cover 31 and the fixing cover 1 in the second direction.

[0044] In another embodiment, only one slide rail 313 may be provided, and only one crimping portion 22 may be provided on the corresponding fixing member 2. The crimping portion 22 and the slide rail 313 are elastically pressed upward toward the aerosol outlet 12 to press the sliding cover 31 or the dustproof structure 3 onto the fixed cover 1, thereby reducing the gap between the dustproof structure 3 and the fixed cover 1.

[0045] In one embodiment, please refer to Figure 2 and Figure 4The slide rail 313 and the fixed portion 21 on the fixed member 2 are arranged in the second direction. During the sliding of the sliding cover 31 relative to the fixed member 2, the fixed portion 21 can also abut against the slide rail 313 in the second direction, thereby providing guidance for the sliding of the sliding cover 31 relative to the fixed member 2. In an embodiment in which two slide rails 313 are provided, both slide rails 313 can abut against the fixed portion 21 in the second direction. In this way, the sliding cover 31 can only slide relative to the fixed member 2 in the direction in which the slide rails 313 extend, thereby improving the guidance of the sliding of the sliding cover 31 relative to the fixed member 2.

[0046] For some examples, please refer to Figure 2 and Figure 3 , each slide rail 313 that is elastically pressed upward by the crimping portion 22 toward the aerosol outlet 12 has a mating surface 3130 facing the crimping portion 22, and the crimping portion 22 can be fitted with the mating surface 3130 of the slide rail 313. The mating surface 3130 extends in the first direction, and the mating surface 3130 includes positioning surfaces 3131 located at both ends of the extension direction of the slide rail 313, and also includes an intermediate connecting surface 3132 located between the two positioning surfaces 3131.

[0047] When the aerosol outlet 12 is facing upward, the distance between the positioning surface 3131 and the fixed cover 1 is smaller than the distance between the intermediate connecting surface 3132 and the fixed cover 1. When the crimping portion 22 elastically presses against the positioning surface 3131, the elastic deformation of the slide rail 313 is smaller than the elastic deformation of the slide rail 313 when the crimping portion 22 elastically presses against the intermediate connecting surface 3132. When the sliding cover 31 slides relative to the fixing member 2, when the sliding cover 31 is in the first position, the crimping portion 22 elastically presses against the positioning surface 3131 at one end of the slide rail 313. When the sliding cover 31 is in the second position, the pressing portion 22 elastically presses against the positioning surface 3131 at the other end of the sliding rail 313. In this way, when the sliding cover 31 needs to move, a force needs to be applied to the sliding cover 31 to cause it to produce more elastic deformation so that the sliding cover 31 can be smoothly moved from the first position or the second position. In this way, the sliding cover 31 can be positioned in the first position and the second position by the positioning surfaces 3131 that are close to the fixed cover 1 and are located at both ends of the sliding rail 313, thereby improving the structural stability and reliability of the dust cover assembly.

[0048] For further information, please refer to Figure 2 and Figure 3In some embodiments, the mating surface 3130 on the slide rail 313 further includes a transition surface 3133 connected between the positioning surface 3131 and the intermediate connecting surface 3132. The distance between the transition surface 3133 and the fixed cover 1 gradually decreases in the first direction and from the intermediate connecting surface 3132 to the positioning surface 3131. For example, in one embodiment, the transition surface 3133 can be a slope, or in other embodiments, the transition surface 3133 can also be an arc surface or a curved surface. This helps to improve the smoothness of the sliding cover 31 relative to the fixed component 2 and reduce the sticking feeling of the sliding cover 31 when moving out of the first position or the second position.

[0049] In other embodiments, the distance between the positioning surface 3131 and the fixed cover 1 can be set to be greater than the distance between the intermediate connecting surface 3132 and the positioning surface 3131, so that the elastic pressing force between the crimping portion 22 and the positioning surface 3131 is greater than the elastic pressing force between the crimping portion 22 and the intermediate connecting surface 3132. The sliding cover 31 can be positioned at the first position and the second position by increasing the elastic pressing force between the crimping portion 22 and the slide rail 313, thereby improving the structural stability and reliability of the dust cover assembly.

[0050] For some examples, please refer to Figures 1 to 4 The dustproof structure 3 also includes a top cover 32, which is located on the side of the sliding cover 31 facing away from the fixed cover 1. The top cover 32 can be connected to the sliding cover 31 by a snap buckle or a screw. After the top cover 32 is connected to the sliding cover 31, the top cover 32 can cover the notch of the sinking groove 312 on the sliding cover 31, so that the top cover 32 can cover the sliding rail 313 and the crimping portion 22, reducing dust or foreign matter that enters the matching position of the sliding rail 313 and the crimping portion 22, and enabling the sliding cover 31 to slide smoothly relative to the fixing member 2; and when the sliding cover 31 is in the first position, the aerosol outlet 12 can also be covered by the top cover 32.

[0051] Of course, in some other embodiments, the top cover 32 may not be provided in the dustproof structure 3. By increasing the size of the frame 311 in the first direction, the aerosol outlet 12 can be blocked by the sliding cover 31 when the sliding cover 31 is in the first position to prevent larger foreign matter from entering the accommodating cavity from the aerosol outlet 12.

[0052] In one embodiment, in order to facilitate the operator to push the dustproof structure 3, a protrusion 321 can be provided on the outer surface of the top cover 32 facing away from the fixed cover 1. The protrusion 321 can be integrally formed with the top cover 32. The operator can hold the protrusion 321 and drive the sliding cover 31 to slide back and forth in the first direction through the top cover 32.

[0053] An embodiment of the present application also provides an aerosol generating device, which includes a device body and a dust cover assembly in any of the above embodiments. The dust cover assembly can be connected to the device body through a snap-fit ​​structure. The device body has a accommodating cavity. The aerosol outlet 12 of the fixed cover 1 in the dust cover assembly is connected to the accommodating cavity. The sliding cover 31 in the dust cover assembly is arranged on the side of the fixed cover 1 facing away from the device body.

[0054] The above examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. Those skilled in the art of the present invention can make some simple deductions, modifications or substitutions based on the concept of the present invention.
