[0055] Optionally, as shown in Figure 3 and Figure 4 The inner side wall of the side, away from the plug-in port 22, of the filter box 2 is concave to form a mounting groove 23, which is used to mount the elastic assembly 3.

[0056] In the case that the filter screen plate 25 is inserted into the filter box 2, the filter screen plate 25 is partially located in the mounting groove 23 and abuts against the elastic assembly 3.

[0057] It should be noted that the elastic assembly 3 is embedded in the mounting groove 23 of the inner wall of the filter box 2, which avoids occupying the effective space of the ventilation channel 21 and ensures the smoothness of the ventilation channel 21; the mounting groove 23 can limit and fix the elastic assembly 3, so as to avoid displacement or falling of the elastic assembly 3 during the insertion and extraction of the filter screen plate 25, and ensure that the elastic assembly 3 is always in the correct position and provides stable elastic support.

[0058] In the case that the filter screen plate 25 is inserted into the filter box 2, the filter screen plate 25 is partially located in the mounting groove 23 and abuts against the elastic assembly 3.

[0059] Optionally, as shown in Figure 3 the elastic assembly 3 comprises a boosting piece 31 and an elastic piece 32;

[0060] The boosting piece 31 is embedded in the mounting groove 23, and the boosting piece 31 abuts against the filter screen plate 25.

[0061] One end of the elastic piece 32 is connected to the boosting piece 31, and the other end is connected to the bottom wall of the mounting groove 23, so as to push the boosting piece 31 to move to one side of the insertion port 22.

[0062] It should be noted that the boosting piece 31 can provide uniform and stable elastic force, so that the filter screen plate 25 can be smoothly pushed out when disassembled, and the problems of jamming or loosening caused by uneven elastic force are avoided.

[0063] In addition, the boosting piece 31 and the elastic piece 32 can be maintained or replaced separately, without the need to replace the entire elastic assembly 3, thereby reducing the maintenance cost.

[0064] Optionally, as shown in Figure 2 and Figure 3 the boosting piece 31 comprises a boosting plate 311 and a limiting block 312 connected to each other, and the boosting plate 311 abuts against the filter screen plate 25.

[0066] The limiting groove 232 is matched with the cross-sectional size of the elastic member 32, and the limiting groove 232 and the booster plate 311 and the limiting block 312 form a placement cavity to place the elastic member 32, one end of the elastic member 32 is connected to the bottom wall of the limiting groove 232, and the other end is connected to the limiting block 312.

[0067] It should be noted that the booster plate 311 is embedded in the embedded groove 231, which can further ensure the sealing effect, prevent dust or pollutants from entering the inside of the cabinet 1 from the gap between the booster plate 311 and the mounting groove 23, provide overall sealing performance, and avoid the problem of poor sealing or reduced filtering effect caused by installation deviation;

[0068] The cross-sectional size of the limiting groove 232 is matched with the cross-sectional size of the elastic member 32, and the limiting groove 232 and the booster plate 311 and the limiting block 312 form a placement cavity, which can effectively limit the movement range of the elastic member 32, prevent the elastic member 32 from being separated from the specified position due to excessive compression, ensure that the elastic member 32 is always in the correct working state, and ensure the normal operation of the equipment.

[0069] Optionally, as shown in Figure 2 and Figure 7 The first limiting plate 4 is movably connected to the inner side wall of the filter box 2, and the first limiting plate 4 blocks the opening of the limiting groove 232 to limit the limiting block 312 from being separated from the limiting groove 232.

[0070] The filter box 2 further comprises a limiting protrusion 24 on the inner side wall, and the limiting protrusion 24 limits the movement of the first limiting plate 4 to avoid the first limiting plate 4 from blocking the opening of the embedded groove 231.

[0071] It can be understood that when the first limiting plate 4 blocks the opening of the embedded groove 231, the filter screen plate 25 will be blocked by the first limiting plate 4, and the filter screen plate 25 cannot abut against the booster plate 311. The limiting protrusion 24 limits the movement range of the first limiting plate 4, avoids the first limiting plate 4 from blocking the opening of the embedded groove 231, ensures that the filter screen plate 25 can be smoothly embedded in the embedded groove 231, and ensures the smooth installation and disassembly process of the filter screen plate 25.

[0072] In addition, the first limiting plate 4 blocks the opening of the limiting groove 232, which can effectively limit the movement range of the limiting block 312, prevent the limiting block 312 from being separated from the limiting groove 232 during the plugging process of the filter screen plate 25, ensure that the elastic assembly 3 is always in the correct working position, and improve the stability and reliability of the structure.

[0073] The first limiting plate 4 is movably connected to the side wall of the filter box 2, and the first limiting plate 4 can be removed from the limiting groove 232 by moving the first limiting plate 4, so that the elastic assembly 3 can be taken out, thereby facilitating maintenance and replacement, simplifying the maintenance process and improving work efficiency.

[0074] In some embodiments, one side of the first limiting plate 4 is rotatably connected to the inner side wall of the filter box 2, and when the first limiting plate 4 is in a natural falling state, the first limiting plate 4 blocks the opening of the limiting groove 232.

[0075] In other embodiments, the first limiting plate 4 is slidably connected to the inner side wall of the filter box 2, and the inner side wall of the filter box 2 is provided with a sliding groove for slidably connecting the first limiting plate 4.

[0076] Optionally, as shown in Figure 5 The boost plate 311 is movably connected to the limiting block 312.

[0077] It should be noted that in some embodiments, the cross-sectional size of the insertion port 22 is consistent with the cross-sectional size of the embedded groove 231, the boost plate 311 is inserted into the embedded groove 231 through the insertion port 22, and the limiting block 312 cannot pass through the insertion port 22. Therefore, after the boost plate 311 is inserted into the insertion port 22, the limiting block 312 is fixed relative to the filter box 2 inside the filter box 2, which facilitates the installation and disassembly of the boost piece 31, thereby facilitating installation and maintenance.

[0078] In some embodiments, the boost plate 311 is recessed to form a groove adapted to the limiting block 312, the limiting block 312 is inserted into the boost plate 311, and the limiting block 312 and the boost plate 311 are both provided with through holes for inserting a limiting pin. The limiting pin fixes the limiting block 312 relative to the boost plate 311, and the side of the limiting block 312 close to the filter screen plate 25 does not protrude from the contact surface of the boost plate 311 and the filter screen plate 25, which ensures uniform thrust and avoids the problems of jamming or loosening caused by uneven thrust.

[0079] In some other embodiments, the ventilation channel 21 is provided with a sliding entrance on the side close to the outer side, the size of the sliding entrance is matched with the size of the booster plate 311, the booster plate 311 can be slid into the sliding entrance and then embedded into the embedded groove 231 along the insertion path of the filter screen plate 25. It can be understood that when the sliding entrance is adopted, the booster plate 311 and the limiting block 312 can be connected and fixed in advance outside the filter box 2, or the booster plate 311 and the limiting block 312 are integrally connected, and both can be successfully installed. The present embodiment does not make specific limitation on this.

[0080] Optionally, as shown in Figures 3 to 5 The filter box 2 is slidably connected with a second limiting plate 5, the second limiting plate 5 is arranged on the side of the plug-in interface 22, and the second limiting plate 5 moves to the side of the plug-in interface 22 and abuts against the filter screen plate 25 to limit the movement of the filter screen plate 25 out of the filter box 2.

[0081] It can be understood that after the filter screen plate 25 is arranged in the filter box 2, the elastic assembly 3 gives the filter screen plate 25 an outward moving force, and the second limiting plate 5 can prevent the filter screen plate 25 from being pushed out by the elastic assembly 3, thereby improving the safety and reliability of the equipment.

[0082] In addition, the second limiting plate 5 can be slid to release the limitation on the filter screen plate 25, and the filter screen plate 25 is pushed out by the elastic assembly 3, thereby facilitating the taking.

[0084] The second limiting plate 5 blocks the clamping opening 221 and abuts against the clamping block 251 to limit the movement of the filter screen plate 25 out of the filter box 2.

[0085] It can be understood that the cooperation of the clamping block 251 and the clamping opening 221 and the abutting of the second limiting plate 5 further enhance the fit between the filter screen plate 25 and the filter box 2, effectively prevent dust and pollutants from entering the inside of the cabinet 1 from the gap, and improve the sealing performance.

[0086] In some embodiments, after installation, the outer side wall of the filter screen plate 25 is in the same plane as the outer side wall of the filter box 2. When the operator pushes the filter screen plate 25 to be flush with the outer side wall of the filter box 2, the second limiting plate 5 can be used for limiting and fixing, without the need to continue to push the filter screen plate 25, thereby facilitating the installation of the filter screen plate 25.

[0087] Optionally, as shown in the drawings, the cabinet 1 is also rotationally connected with a cabinet door 11, and the plug-in interface 22 is arranged on the side of the filter box 2 close to the cabinet door 11. Figure 6
