[0026] like Figure 3 As shown, a connecting block 404 is fixedly installed on the back of the rotating disk 403 , and the connecting block 404 is located on the inner side of the movable frame 405 and is movably connected to the movable frame 405 .

[0027] like Figure 4 As shown, the bottom of the mounting plate 409 is provided with evenly distributed springs 411 , and the bottom of the springs 411 is fixedly connected to the cleaning plate 410 .

[0028] The effect achieved by the above components is: by setting the spring 411 to apply pressure to the cleaning plate 410, a good contact between the cleaning plate 410 and the filter screen 9 is maintained, thereby ensuring the cleaning effect of the filter screen 9.
