Case 1 is fixed and the intercommunication has more change case 7 at the lateral wall that is close to filtering mechanism, and more change case 7's inside is opened has the cavity, and the cavity is first chamber 8, second chamber 9 and third chamber 10 respectively by turning right left. First cavity 8, second cavity 9 and third cavity 10 communicate each other, and the equal coplane of inner wall of first cavity 8, second cavity 9 and third cavity 10, and first cavity 8, second cavity 9 and third cavity 10 can hold a filter screen 5 and freely slide. The bottom of the second chamber 9 is provided with a through hole for the accommodating frame 4 to pass through, and the through hole enables the second chamber 9 and the case 1 to be communicated with each other. The third chamber 10 is only wide enough to accommodate one filter screen 5. A first pressure spring 11 is fixed on the inner wall of the left side of the first chamber 8, the axial direction of the first pressure spring 11 is parallel to the horizontal plane, a push plate 12 is fixedly connected to the right end of the first pressure spring 11, and the push plate 12 freely slides in the first chamber 8 along the horizontal direction.
