[0036] Please refer to Figure 1 and Figure 2 The rotating shaft 202 is provided with a transmission assembly 6, the transmission assembly 6 comprises a driving pulley 601 fixed on the rotating shaft 202, the rack 1 is rotatably connected with a rotating rod 602, the rotating rod 602 is fixed with a driven pulley 603 in transmission connection with the driving pulley 601 through a belt, the rotating rod 602 is fixed with a short push plate 204 and a long push plate 205 through a fixing ring, the transmission assembly 6 is fixed with the short push plate 204 and the long push plate 205, and the side surface of the filter disc 203 is fixed with a stress plate 206.

[0037] Specifically, when the short push plate 204 is vertically downward against the force receiving plate 206 from one end of the rotating rod 602, the filter disc 203 moves to the end of the first stroke, and the filter hole of the filter disc 203 is not in contact with the cleaning rod 503.
