The control valve built into the discharge pipe 16 is opened to allow the cleaned sewage to flow back into the water tank 17, and is filtered through the filter box 22, so that the filtered cleaning water re-enters the water tank 17, while the impurities remain in the filter box 22. When the filter box 22 needs to be cleaned, the operator needs to pull the handle 30, so that the block 26 can leave the slot 24 of the filter box 22 through the pull rod 27, so that the filter box 22 loses its restraint, and the filter box 22 can be removed by pulling the handle 23 for cleaning or replacement. When installing the filter box 22, it is necessary to first pull the handle 30 so that the block 26 enters the limiting groove 25, and then the filter box 22 can be installed back to its original position, and then the force on the handle 30 is released, and the spring 28 releases the tension to clamp the block 26 into the slot 24, and the installation is completed.
