[0035] When the filter mechanism is blocked, the water flow from the filter plate 131 to the side of the impeller 141 is reduced, and a small amount of water flow cannot quickly drive the impeller 141 to rotate, causing the rotational speed of the impeller 141 to decrease, and the rotational speed of the driving gear 171 on the transmission rod 170 connected thereto to decrease.
