[0024] A movable groove 11 is provided on the inner wall of the connecting frame 9, and a cleaning brush plate 12 is provided in the middle of the connecting frame 9, and a connecting plate 13 for docking with the connecting frame 9 is provided above the cleaning brush plate 12; a connecting shaft 14 is provided in the middle of the upper part of the cleaning brush plate 12, a motor 15 is installed above the connecting plate 13, and the output end of the motor 15 is docked with the connecting shaft 14 through a coupling; a protective cover 16 is sleeved on the outer side of the motor 15, and both side surfaces of the connecting plate 13 close to the protective cover 16 are provided with hanging rings 17, and both ends of the cleaning brush plate 12 are penetrated by limit pins 18; the outer end of the limit pin 18 is docked and inserted into the inside of the movable groove 11, and a first spring 19 is commonly connected between the inner side of the limit pin 18 and the cleaning brush plate 12, and the limit pin 18 forms a telescopic structure through the first spring 19 and the cleaning brush plate 12, and the movable groove 11 is annular, and the bottom of the cleaning brush plate 12 fits the surface of the filter plate 10.

[0025] In the specific implementation, the limit pins 18 at both ends of the cleaning brush plate 12 are first pressed inward at the same time, and the pressed limit pins 18 move toward the inside of the cleaning brush plate 12 while squeezing the first spring 19, and then the cleaning brush plate 12 is placed inside the connecting frame 9 so that the limit pins 18 correspond to the opening of the movable groove 11, and then the pressed limit pins 18 are loosened.

[0027] During the specific implementation, when the connecting frame 9 and the filter plate 10 are pushed downward for docking, the connecting seat 20 at the bottom of the filter plate 10 is fitted with the outer side of the support seat 8, and the connecting seat 20 moves downward synchronously with the downward movement of the connecting frame 9. During the downward movement, the connecting seat 20 is squeezed to a certain extent with the docking block 22. The docking block 22 squeezed by the external force moves along the guide rod 23 toward the inside of the support seat 8 while squeezing the second spring 24 sleeved on the outside of the guide rod 23 until the connecting frame 9 is pushed downward to the limit position, so that the position of the docking block 22 corresponds to the position of the docking groove 21. At this time, the docking block 22 that is not squeezed by the external force can be automatically reset outward and inserted into the inside of the docking groove 21 by the elastic force of the second spring 24. By arranging a docking block 22 that can automatically reset inside the support seat 8 to dock with the docking groove 21, the connecting frame 9 can be limited, so that the dehydration filter can be conveniently installed with the connecting frame 9 limited.
