The filter assembly 1 includes a filter barrel 101, which penetrates the top surface of the filter chamber 5 and is movably connected to the main body 2. Specifically, the top surface of the filter bucket 101 penetrating the filter chamber 5 facilitates the direct entry of sewage from the filter bucket 101 into the main body 2, and the side support at the penetration point makes the filter bucket 101 more stable during rotation. The bottom surface of the filter barrel 101 is provided with a fixed sleeve 102, and the fixed sleeve 102 is rotatably connected to the main body 2. The surface of the fixed sleeve 102 is fixed with a limiting ring 103, and the bottom surface of the limiting ring 103 is provided with an array of balls 110, and the balls 110 are rotatably connected to the filter chamber 5.
