Similarly, at least two No. 2 fixing blocks 782 are fixedly connected to the bottom of the filter box 4 to keep the long axis 78 rotating smoothly. A flow groove 741 is opened inside the fixing plate 74. Since the long rod 72 is hollow, the flow groove 741 is connected to the long rod 72. A guide pipe 742 is provided in the groove opened on the inner wall of the filter box 4 below the fixing plate 74. One side of the guide pipe 742 is connected to the inner wall of the fixing plate 74. The baffle plate 71 is connected to the flow groove 741 on the top and the water pipe 63 on the other side. When the nozzle 62 sprays water, the surface of the baffle plate 71 will be stained with dust and become muddy after encountering water. Therefore, a water outlet hole 711 is opened on the surface of the baffle plate 71. When spraying water, a part of the water source in the water pipe 63 can enter the flow groove 741 in the fixed plate 74 through the guide pipe 742 connected to the water pipe 63, and then flow through the long rod 72, and flow out from the guide groove 712 connected to the long rod 72 and the water outlet hole 711 connected to the guide groove 712, so as to clean the dirt on the surface of the baffle plate 71.
