The connecting pipe 7 can facilitate liquid inlet and gas outlet. The upper end surface of the filter box body 1 is provided with an air inlet, and the upper end surface of the filter box body 1 is threaded. The bolt is fixedly connected with an installation box 8, and the installation box 8 can provide a place for installing an air pump 10.

The upper end surface of the installation box 8 is provided with a liquid inlet 9, and the upper end surface of the filter box body 1 is fixedly connected with an air pump 10. By setting the air pump 10, air can be blown into the filter component 4. The air outlet end of the air pump 10 is fixedly connected with an air delivery pipe 15. By setting the air delivery pipe 15, it is convenient for the air pump 10 to transport air to the filter component 4. The air delivery pipe 15 runs through the installation box 8 and the air inlet and extends into the filter component 4. The installation box 8, two partition box shells 11 are fixedly connected inside, and the partition box shells 11 can provide a place for installing the electric telescopic rod 12.
