[0033] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:

[0034] When replacing the corrugated filter cotton body 3, pull the lever 407 upwards. At this time, the moving block 402 is not squeezed by the trapezoidal pressing block 406. The elastic force of the second spring 408 can push the moving block 402 and the insert block 403 to move, allowing the insert block 403 to move out of the slot 409. Pulling the filter frame 2 upwards simultaneously moves the corrugated filter cotton body 3 upwards, allowing it to be removed and replaced from inside the outer frame 1. This is very convenient as it does not require removing multiple screws. Push the push plate 505 to the side away from the inflation box 501, pull the lever 407 upwards, and insert the replaced corrugated filter cotton body 3 along with the filter frame 2 into the outer frame 1. The elastic force of the first spring 405 is greater than that of the second spring 408. Release the lever 407. The elastic force of spring 405 can push the trapezoidal extrusion block 406 down to extrude and press the inclined surface of the moving block 402, which can cause the moving block 402 to move the insertion block 403, so that the insertion block 403 can be inserted into the slot 409, which can fix the filter frame 2 without the need for multiple screws on the thread. The steps are simple and realize the function of easy replacement of the wavy filter cotton body 3. When the push plate 505 is released, the elastic force of spring 506 pushes the piston 502 to move, which fills the gas inside the air chamber 507 into the sealing air bag 510 through the air pipe 512, so that the sealing air bag 510 enters the sealing groove 511, which can ensure the seal between the outer frame 1 and the filter frame 2 and prevent gas from passing through the gap between the outer frame 1 and the filter frame 2.
