[0025] In one embodiment of the utility model, by means of a first brush holder 8 disposed on both sides of the filter unit 4, the filter unit 4 can be pulled up and down so that both sides of the filter unit 4 can be cleaned by the first brush 81, and then the inner wall of the device body 1 can be cleaned in cooperation with the second brush 91, so that the cleaning of the device is more comprehensive, the cleaning effect is improved, and thus indirectly affects the filtering quality in subsequent use.

[0026] In one example of the utility model, during use, the device body 1 is filled with water, the liquid inlet 2 and the liquid outlet 3 are blocked, the filter unit 4 is pulled up and down, and both sides of the filter unit 4 are repeatedly cleaned by the first brush 81. In addition, when the filter unit 4 moves upward, under the action of the floating block 92, the second brush holder 9 moves upward along the movable rod 10 through the movable hole 93, and cleans the inner wall of the device body 1 by the second brush 91. When the filter unit 4 moves downward, the lower end of the filter unit 4 abuts against the upper end of the second brush holder 9 to press the second brush holder 9 down, and then the inner wall of the device body 1 is repeatedly cleaned by the second brush 91, the liquid outlet 3 is opened, and the cleaned sewage is discharged. This is repeated several times to complete the cleaning of the device.

[0027] like Figure 4 As shown, as a preferred embodiment of the present utility model, a slot 41 is provided at the bottom of the filter unit 4 at a position corresponding to the second brush holder 9 , and a damping ring 42 is fixedly provided in the slot 41 .
