The outer wall of the right end of the rotating block 11 is cylindrical and slidably connected to the inner wall of the left end of the moving block 12. With the rotation of the rotating block 11, the moving block 12 reciprocates vertically on the inner wall of the upper end of the right-angle tube 13. When the moving block 12 moves downward, it drives the connecting block 16 to move backward. The filter 15 fixed at the rear end of the connecting block 16 moves backward under the guidance of the support rod 14; when the moving block 12 moves upward, the connecting block 16 moves forward, thereby realizing the forward and backward movement of the filter 15. At the same time, the electric telescopic rod 6 is started, and the electric telescopic rod 6 drives the nozzle 7 to move in the vertical direction on the guide rail 8. The water pump in the water delivery device 4 delivers the water in the water tank to the nozzle 7 through the water delivery pipe 5. The nozzle 7 sprays water to the filter 15 for cleaning. The waste liquid after cleaning falls into the collecting assembly at the bottom of the air inlet cylinder 2. The waste liquid tank 20 in the collecting assembly is used to collect the waste liquid after cleaning the filter 15. When installing the waste liquid tank 20, pull the block 19 downward to push the waste liquid tank 20 into the fixing frame 3. The block 19 moves upward under the action of the spring 18 and slides on the rear end outer wall of the waste liquid tank 20 to fix the waste liquid tank 20. When the waste liquid tank 20 needs to be removed, pull the block 19 downward to make it leave the rear end outer wall of the waste liquid tank 20, so that the waste liquid tank 20 can be released.
