The installed first drive motor 2 enables the output shaft of the first drive motor 2 to drive the first rotating rod 3 to rotate, and then the first rotating rod 3 can push the push plate 4 to move, so that the push plate 4 can push out the debris on the top of the filter 15. At the same time, due to the shape of the push plate 4, it is convenient for the debris to slide to the top of the filter 15, and at the same time, it is convenient to protect the cleaning member 14 on the other side of the filter 15. At the same time, the opened slide 8 enables the second drive motor 9 to be installed on the side of the test base 1, so that the output shaft of the second drive motor 9 can drive the second rotating rod 10 to rotate, so that the second rotating rod 10 can drive the slider 11 to move when rotating, and at the same time, the rotating second rotating rod 10 can be installed on the inner wall of the slide 8.
