[0024] Specifically, the side of the fan blade 76 away from the circular filter plate 73 is hemispherical in shape, so as to reduce the resistance to the water flow.

[0025] In this implementation, please refer to Figure 3 After the circulating water contacts the hemisphere, the hemisphere guides the circulating water, thereby reducing the resistance of the fan blades 76 to the circulating water.

[0026] Specifically, the axis of the fan blade 76 and the connecting shaft 74 coincides with the axis of the housing 71 , the dial plate 75 and the connecting shaft 74 are vertically arranged, and the circular filter plate 73 and the dial plate 75 are parallelly arranged.
