When the mounting ring 54 moves, it can drive the connecting cylinder 53 to move, and the connecting cylinder 53 can drive the sliding plug 52 to move. During the movement of the sliding plug 52, the gas inside the sealing cylinder 51 can be pressed into the inside of the sealing ring 4 through the connecting pipe 56, so that the sealing ring 4 is inflated and expanded, so that the sealing ring 4 presses the filter element 1, so that the sealing ring 4 and the filter element 1 are closely fitted. In this case, the sealing ring 4 can apply pressure to the filter element 1. This design can improve the sealing performance between the filter element 1 and the mounting seat 2 to prevent water leakage;
[0022] A pressing assembly is provided on the filter element 1, and the pressing assembly includes a fixing ring 61, a plurality of connecting rods 62 and a pressing ring 63.
