The above scheme of installing the pressing block 2 on the fixed cover 1 and arranging the sliding rail 311 on the sliding cover 31, and switching the sliding rail 311 relative to the pressing block 2 between the first position and the second position, does not need to arrange a sliding groove on the fixed cover 1, and can avoid the sliding of the dustproof structure 3 being not smooth due to the entry of sundries or dust into the sliding groove.

[0034] The pressing portion 21 can be elastically floated relative to the fixed cover 1 towards the aerosol outlet 11, and the pressing portion 21 can be elastically abutted against the slide rail 311 towards the aerosol outlet 11, so that the pressing portion 21 can exert an elastic force on the slide rail 311 to press the slide cover 31 against the fixed cover 1 during the reciprocating sliding of the slide cover 31 relative to the pressing block 2 or the fixed cover 1 between the first position and the second position, so that the entire dustproof structure 3 is pressed against the fixed cover 1 by the slide cover 31, which can reduce the dust entering the position of the slide rail 311 and the pressing portion 21 from the gap between the dustproof structure 3 and the fixed cover 1, and can help the dustproof structure 3 to slide smoothly relative to the fixed cover 1.

[0035] In some embodiments, referring to Figure 2 , In some embodiments, referring to Figures 4 to 6 , the dust cover assembly comprises an elastic member connected with the fixed cover 1, the pressing block 2 comprises the pressing portion 21 and an elastic matching portion 22 fixedly connected with the pressing portion 21, and the elastic member can exert an elastic force on the elastic matching portion 22 to elastically abut the pressing portion 21 against the slide rail 311 towards the aerosol outlet 11, so that the structure reliability and stability of the pressing portion 21 pressed against the slide rail 311 can be ensured by the elastic member.

[0036] In an embodiment, the pressing block 2 is located on the side of the fixed cover 1 towards the aerosol outlet 11, the elastic member comprises a spring, the spring can be a tension spring, one end of the spring is fixed on the fixed cover 1, the other end is connected with the pressing block 2, and the spring exerts an elastic force on the pressing block 2 towards the fixed cover 1, so that the pressing block 2 can be installed on the fixed cover 1 by the elastic member, the portion of the pressing block 2 matched with the slide rail 311 is the pressing portion 21, and the portion of the pressing block 2 connected with the spring is the elastic matching portion 22.

[0037] In another embodiment, the elastic member further comprises a leaf spring, the middle part of the leaf spring is fixed on the fixed cover 1, the end part of the leaf spring is connected with the pressing block 2, the leaf spring exerts an elastic force on the pressing block 2 towards the fixed cover 1, the pressing block 2 is installed on the fixed cover 1 by the leaf spring, the portion of the pressing block 2 matched with the slide rail 311 is the pressing portion 21, and the portion of the pressing block 2 connected with the leaf spring is the elastic matching portion 22.

[0038] In an embodiment, referring to Figures 3 to 6The pressing block 2 as a whole can be elastically floated and mounted on the fixed cover 1 in the direction of the aerosol outlet 11 through an elastic member, and the pressing block 2 is extended upward in the direction of the aerosol outlet 11. The pressing block 2 includes an elastic fitting portion 22 and a pressing portion 21 at both ends thereof, and also includes an intermediate connecting portion 23 connecting the elastic fitting portion 22 and the pressing portion 21. The extension directions of the elastic fitting portion 22 and the pressing portion 21 are both perpendicular to the direction of the aerosol outlet 11 and also perpendicular to the sliding direction of the sliding cover 31. A through-hole is provided on the fixed cover 1, and the intermediate connecting portion 23 is located in the through-hole. The elastic fitting portion 22 and the pressing portion 21 are located on both sides of the fixed cover 1. In order to facilitate the installation of the pressing block 2 on the fixed cover 1, the pressing block 2 can be set as a split structure; and one or two elastic fitting portions 22 and pressing portions 21 can be provided in the pressing block 2, and the two elastic fitting portions 22 are in opposite directions, and the two pressing portions 21 are in opposite directions, so that the pressing block 2 forms an I-shaped structure.

[0039] The elastic member is located on the side where the elastic fitting portion 22 is located. The elastic member includes a spring piece 4. The spring piece 4 has a connecting portion 41 and a suspension portion 42. The connecting portion 41 can be fixed to the fixed cover 1 by screws. The suspension portion 42 includes a cantilever. The cantilever is connected to the connecting portion 41. The cantilever is cantilevered toward the direction of the pressing block 2. The cantilever corresponds to the pressing block 2 at the middle position of its extension direction. The cantilever is arched in the direction of the aerosol outlet 11 toward the fixed cover 1, so that the arched portion corresponds to the pressing block 2. The elastic fitting portion 22 on the pressing block 2 is located on the side of the arched portion facing away from the fixed cover 1. One or two cantilevers can be provided, one cantilever is located on one side of the pressing block 2 and is elastically fitted. The two cantilevers are located on both sides of the pressing block 2, and the two cantilevers are respectively pressed against the corresponding elastic matching parts 22. The deformation of the cantilever can exert an elastic force on the elastic matching part 22 to make the elastic matching part 22 move away from the fixed cover 1 in the direction of the aerosol outlet 11; in this way, the elastic member exerts a force on the sliding cover 31 through the pressing block 2 to make the sliding cover 31 move toward the fixed cover 1, so that the sliding cover 31 or the entire dustproof structure 3 is pressed tightly on the fixed cover 1, reducing dust entering the position of the slide rail 311 and the crimping part 21 from the gap between the dustproof structure 3 and the fixed cover 1, which helps to make the dustproof structure 3 slide smoothly relative to the fixed cover 1.

[0040] In another embodiment, the elastic member may further include a spring, which is a compression spring. The elastic member is located between the fixed cover 1 and the elastic fitting portion 22. One end of the elastic member is connected to the fixed cover 1, and the other end is connected to the elastic fitting portion 22, or the other end may also be elastically pressed against the elastic fitting portion 22. The elastic member applies an elastic force to the elastic fitting portion 22 so that the elastic fitting portion 22 moves upward away from the fixed cover 1 in the direction of the aerosol outlet 11.

[0041] For some examples, please refer to Figure 3 and Figure 5For the sliding cover 31, the sliding cover 31 has a guide groove 313, the extension direction of the guide groove 313 is the same as the extension direction of the slide rail 311, the crimping part 21 is located in the guide groove 313, the position of the crimping part 21 in the vertical direction of the extension direction of the slide rail 311 can be limited by the groove side wall of the guide groove 313, and the guiding property of the sliding cover 31 relative to the pressing block 2 is ensured; in addition, the guide groove 313 can be arranged on the sliding cover 31, and the crimping part 21 is located in the guide groove 313, so as to reduce the size of the sliding cover 31 protruding from the aerosol outlet 11 to the upper side of the sliding cover 31, thereby reducing the size of the entire dustproof structure 3 protruding from the fixed cover 1, and the miniaturization design of the dustproof structure 3 is realized.

[0042] In an embodiment, please continue to refer to Figure 3 and Figure 5 The slide rail 311 is located on the groove bottom wall of the guide groove 313, the long hole extending in the extension direction of the slide rail 311 can be arranged on the groove bottom wall of the guide groove 313, the middle connecting part 23 of the pressing block 2 passes through the long hole, the crimping part 21 is located in the guide groove 313 and contacts the groove bottom wall of the guide groove 313, and the groove bottom wall on the side of the long hole forms the slide rail 311.

[0043] According to the number of crimping parts 21, two slide rails 311 can be arranged on both sides of the pressing block 2 in the extension direction of the slide rail 311, and each crimping part 21 protrudes towards the corresponding slide rail 311 to elastically abut against the corresponding slide rail 311 in the direction of the aerosol outlet 11, so that the structure of the two slide rails 311 and the two crimping parts 21 elastically abutting against each other can make the sliding cover 31 bear force uniformly in the vertical direction of the extension direction of the slide rail 311, and help to make the gap between the dustproof structure 3 and the fixed cover 1 uniform.

[0044] The middle connecting part 23 of the pressing block 2 is located between the two slide rails 311, and in the process of the sliding cover 31 sliding relative to the pressing block 2, the side wall of the slide rail 311 abuts against the pressing block 2 in the vertical direction of the extension direction of the slide rail 311, so as to limit the position of the sliding cover 31 in the vertical direction of the extension direction of the slide rail 311, thereby improving the guiding property of the sliding cover 31 sliding relative to the pressing block 2.

[0045] In other embodiments, the guide groove 313 arranged on the sliding cover 31 can be cancelled, and the crimping part 21 of the pressing block 2 protrudes from the sliding cover 31; or only one slide rail 311 is arranged, and the slide rail 311 elastically abuts against one crimping part 21 on the pressing block 2 in the direction of the aerosol outlet 11.

[0046] In some embodiments, please refer to Figure 3 and Figure 5, the slide rail 311 has a cooperation surface 312 elastically abutting against the crimping part 21 in the direction of the aerosol outlet 11, the cooperation surface 312 extends in the extending direction of the slide rail 311, and the cooperation surface 312 comprises a positioning surface 3121 at both ends and a connecting surface 3122 connected between the two positioning surfaces 3121; in the direction of the aerosol outlet 11, the distance between the positioning surface 3121 and the fixed cover 1 is less than the distance between the connecting surface 3122 and the fixed cover 1.

[0047] In addition, when the slide cover 31 is in the first position, the crimping part 21 elastically abuts against the positioning surface 3121 at one end of the slide rail 311; when the slide cover 31 is in the second position, the crimping part 21 elastically abuts against the positioning surface 3121 at the other end of the slide rail 311; when the slide cover 31 is in the intermediate position between the first position and the second position, the crimping part 21 elastically abuts against the connecting surface 3122 of the slide rail 311; the elastic abutting force between the crimping part 21 and the connecting surface 3122 of the slide rail 311 is greater than the elastic abutting force when the crimping part 21 elastically abuts against the positioning surface 3121, so that when the slide cover 31 moves away from the first position or the second position, a greater force needs to be provided to the slide cover 31 to make the slide cover 31 overcome part of the elastic abutting force, so that the slide cover 31 can be positioned in the first position and the second position without external force, and the slide cover 31 is prevented from shaking in the extending direction of the slide rail 311, which helps to ensure the structural stability and reliability of the dustproof cover assembly.

[0048] Further, in some embodiments, please continue to refer to Figure 3 and Figure 5 The cooperation surface 312 further comprises a transition surface 3123 connected between the positioning surface 3121 and the connecting surface 3122, which is arranged in the direction of the aerosol outlet 11, and the distance between the transition surface 3123 and the fixed cover 1 gradually decreases in the direction from the connecting surface 3122 to the positioning surface 3121, so as to facilitate the sliding switching of the slide cover 31 between the first position or the second position and the intermediate position, and help to ensure smooth sliding of the slide cover 31.

[0049] In an embodiment, the transition surface 3123 can be arranged as an inclined surface, which on the one hand facilitates the processing and manufacturing of the cooperation surface 312, and on the other hand can avoid the feeling of jamming when the slide cover 31 slides; of course, in other embodiments, the transition surface 3123 can also be arranged as a circular arc surface or a curved surface.

[0050] Of course, in other embodiments, it is also possible that the distance between the positioning surface 3121 and the fixed cover 1 is greater than the distance between the connecting surface 3122 and the fixed cover 1, so as to ensure that the gap between the slide cover 31 or the dustproof structure 3 and the fixed cover 1 is the smallest when the slide cover 31 is in the first position and the second position, which helps to reduce or even avoid dust or foreign matter from entering the position between the slide rail 311 and the pressing block 2, and helps to ensure smooth sliding of the slide cover 31.

[0051] In some embodiments, in order to avoid the shaking of the sliding cover 31 in the direction perpendicular to the sliding direction during the sliding process, and to improve the guiding of the sliding cover 31, please refer to Figure 2 and Figure 4 , the dustproof cover assembly is provided with a magnetic member installed on the fixed cover 1, and the corresponding sliding cover 31 is provided with a magnetic attraction part. The sliding cover 31 can be made of a magnetic material, or the magnetic attraction part is installed on the sliding cover 31. The magnetic member can be attracted to the sliding cover 31 or the magnetic attraction part on the sliding cover 31 to position the sliding cover 31 at the first position and / or the second position.

[0052] In an embodiment, the magnetic member includes a first magnetic body 51 and a second magnetic body 52 embedded in the fixed cover 1. The first magnetic body 51 and the second magnetic body 52 are both semicircular arc structures. The first magnetic body 51 and the second magnetic body 52 are arranged on both sides of the length direction of the guide groove 313. The sliding cover 31 can be located within the half-enclosed range of the first magnetic body 51 or the second magnetic body 52. The two ends of the first magnetic body 51 or the second magnetic body 52 have a magnetic attraction force on the sliding cover 31 in the direction perpendicular to the extension direction of the sliding rail 311. The magnetic attraction forces of the two ends of the first magnetic body 51 or the second magnetic body 52 on the sliding cover 31 are equal. In this way, the shaking of the sliding cover 31 in the direction perpendicular to the extension direction of the sliding rail 311 during the sliding process between the first position and the second position can be avoided.

[0053] In other embodiments, the first magnetic body 51 and the second magnetic body 52 of the magnetic member can also be magnetic blocks fixed on the fixed cover 1. The magnetic blocks are opposite to the middle position of the sliding cover 31 in the direction perpendicular to the extension direction of the sliding rail 311. The magnetic attraction part is installed on the middle position of the sliding cover 31 in the direction perpendicular to the extension direction of the sliding rail 311. The magnetic blocks and the magnetic attraction part are attracted to each other, which can reduce the shaking amplitude of the sliding cover 31 in the direction perpendicular to the extension direction of the sliding rail 311 during the sliding process.

[0054] In some embodiments, in order to avoid the exposure of the sliding rail 311 and the pressing block 2 outside the dustproof cover assembly, please refer to Figure 1 , Figure 3 and Figure 5The dustproof structure 3 further comprises a top cover 32 connected with the sliding cover 31. The top cover 32 is arranged on the side of the sliding cover 31 away from the fixed cover 1. The top cover 32 is connected with the sliding cover 31 through buckling or screwing, so as to encapsulate the sliding rail 311 and the pressing portion 21 of the pressing block 2 between the top cover 32 and the sliding cover 31. In order to facilitate the buckling connection between the top cover 32 and the sliding cover 31, long holes are arranged on the sliding cover 31 on both sides of the guide groove 313. The sliding cover 31 is provided with a clasp arranged on both side edges of the sliding cover 31 in the direction perpendicular to the extension direction of the sliding rail 311. The top cover 32 is provided with a clamping groove. When the clasp is clamped in the clamping groove, the position of the sliding cover 31 provided with the clasp can be deformed towards the long hole, so as to facilitate the connection between the sliding cover 31 and the top cover 32. After the top cover 32 is connected with the sliding cover 31, the dustproof structure 3 can further shield the aerosol outlet 11 through the top cover 32 when the sliding cover 31 is in the first position.

[0055] In other embodiments, the sliding stroke of the sliding cover 31 can be reduced, and the guide groove 313 is arranged on one side of the sliding cover 31 in the extension direction of the sliding rail 311. In this way, the other side of the sliding cover 31 can shield the aerosol outlet 11 when the sliding cover 31 is in the first position.

[0056] In an embodiment, please continue to refer to Figure 1 、 Figure 3 and Figure 5 In order to facilitate the operator to push the dustproof structure 3 to slide between the first position and the second position, a push button 33 can be arranged on the top cover 32. The push button 33 can be fixedly connected with the top cover 32, for example, riveted or connected through a screw. A push cap 34 can be further arranged on the top of the push button 33, so as to improve the appearance of the dustproof cover assembly.
