[0002] The car air conditioning filter, also known as the car air conditioning filter or air conditioning filter, is a filter specially used for car indoor air purification. Its main function is to filter the air entering the car from the outside to improve the cleanliness of the air and prevent harmful substances from entering the air conditioning system to damage the system. The air conditioning filter is generally fixed to the car by a buckle, and a sealing gasket is provided on the edge of the filter shell, which can play a sealing role. However, the sealing gasket on the edge of the filter shell will make the filter shell clamped on the card slot of the car, making the filter inconvenient to disassemble. For this reason, an air filter with easy disassembly and washing function is proposed. Utility Model Content

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

The sealing mechanism 4 and the limiting mechanism 5 are used in conjunction with each other to facilitate the user to disassemble the filter housing 1.

[0020] like Figure 3 As shown, the sealing mechanism 4 includes a silicone airbag 401 installed in the positioning groove 2, a connecting pipe 405 is connected to the silicone airbag 401, an inflatable cylinder 404 is provided at the end of the connecting pipe 405, a piston 402 is provided in the inflatable cylinder 404, the piston 402 is movably installed in the inflatable cylinder 404, a through hole is opened in the positioning groove 2, the connecting pipe 405 passes through the positioning groove 2 through the through hole, a docking port 406 is provided on the silicone airbag 401, the connecting pipe 405 is connected with the inflatable cylinder 404 through the docking port 406, one end of the connecting pipe 405 is connected to the silicone airbag 401, and the other end of the connecting pipe 405 is connected to the inflatable cylinder 404, one end of the return spring 403 is connected to the bottom of the inflatable cylinder 404, and the other end of the return spring 403 is connected to the piston 402.

[0021] Specifically, after the piston 402 is pushed forward, the gas in the inflation cylinder 404 will be pressed into the silicone airbag 401, causing the silicone airbag 401 to expand and fill the gap between the card slot and the filter housing 1, thereby ensuring the sealing performance of the filter, and the reset spring 403 will provide elastic force for the piston 402 to reset the piston 402. After the piston 402 is reset, the gas in the silicone airbag 401 will be drawn out to loosen the filter housing 1.

[0022] like Figure 4 As shown, the limiting mechanism 5 includes a positioning bracket 501 fixedly mounted on the inflation cylinder body 404, a docking through hole 504 is opened on the positioning bracket 501, an entry and exit through hole 506 is opened in the middle position of the positioning bracket 501, a threaded seat 503 is fixedly mounted at the entry and exit through hole 506 in the middle position of the positioning bracket 501, a limiting screw 502 is installed on the inner thread of the threaded seat 503, a limiting pressure block 505 is fixedly installed at the end of the limiting screw 502, a screw is arranged in the docking through hole 504, the positioning bracket 501 is fixed to one end of the inflation cylinder body 404 by means of screws, the limiting screw 502 is installed in the middle position of the positioning bracket 501 through the threaded seat 503, and the limiting screw 502 passes through the positioning bracket 501 through the entry and exit through hole 506.

[0023] Specifically, rotating the limiting screw 502 in different directions can make the limiting pressure block 505 move forward or backward. When the limiting pressure block 505 moves forward, it will push the piston 402 forward. When the limiting pressure block 505 moves backward, it will move away from the piston 402, so that the piston 402 can be reset.

[0024] It should be noted that the utility model is an air filter with an easy-to-disassemble and wash function. In actual use, the filter housing 1 is first placed in the slot, and then the limiting screw 502 can be rotated forward. After the limiting screw 502 is rotated forward, the limiting pressure block 505 will push the piston 402 forward, and the gas in the inflation cylinder 404 is pressed into the silicone airbag 401, so that the silicone airbag 401 expands to fill the gap between the slot and the filter housing 1, thereby ensuring the sealing performance of the filter, and the limiting screw 502 can be rotated backward. 02. After the limiting screw 502 is rotated backward, the limiting pressure block 505 will be away from the piston 402.
