[0024] Please refer to Figures 1 to 5 As shown, it shows the specific structure of a preferred embodiment of the utility model, including a filter body 10 and a brush 20.

[0025] The filter body 10 is in a circular shape and has a plurality of filter channels 11 therein. The plurality of filter channels 11 are densely spaced and arranged, and each filter channel 11 extends radially along the filter body 10. A plurality of water inlets 12 are provided on the outer peripheral side of the filter body 10. The plurality of water inlets 12 are densely spaced and arranged and are respectively connected to the outer ends of the corresponding filter channels 11. The center of the filter body 10 has a central hole 13. The inner wall of the central hole 13 is provided with a plurality of water outlets (not shown in the figure). The plurality of water outlets are densely spaced and arranged and are respectively connected to the inner ends of the corresponding filter channels 11. In this embodiment, the front and back sides of the filter body 10 are convexly provided with a plurality of first ribs 14, which are densely spaced and extend radially along the filter body 10, and a channel 15 is formed between two adjacent first ribs 14, and the two ends of each channel 15 are respectively connected to the corresponding water inlet 12 and the corresponding water outlet, and the plurality of first ribs 14 can support the filter material to prevent the filter material from being attached to the outer surface of the filter body and affecting the water flow rate. In addition, the front and back sides of the filter body 10 are convexly provided with a plurality of second ribs 16, which are respectively located between two adjacent first ribs 14, and each second rib 16 extends radially along the filter body 10, and the second rib 16 is located at the outer periphery of the filter body 10 to better support the filter material. In addition, a convex portion 17 is convexly provided at the center of the front side of the filter body 10.
