The second convex block 706 contacts the second filter plate 18, and the second convex block 706 is used for vibrating and cleaning the dust on the surface of the second filter plate 18. When the fixing column 601 rotates, the rotation of the fixing column 601 will drive the fixing plate 704 to rotate and move. The rotation and movement of the fixing plate 704 will drive the elastic telescopic rod 705 to rotate and move. The elastic telescopic rod 705 will drive the second convex block 706 to rotate and move. After the second convex block 706 rotates a certain angle, the second convex block 706 will contact the first convex block 703.
