The emptying pipe 03 passes through the drain pipe 02, so that when the sewage amount in the drain cavity 55 is enough, the impeller 56 pump and the emptying structure are used for draining simultaneously, when the sewage amount in the drain cavity 55 is small, air is mixed into the drain cavity 55, so that the impeller 56 of the impeller 56 pump cannot realize the drainage of sewage, and at the moment, the emptying structure continues to work, residual sewage and even air are sucked into the pump water cavity 33 from the drain cavity 55, and then are pumped to a designated position through the emptying pipe 03. The pressure sensing diaphragm 27 is pulled and extruded reciprocally, so that the residual sewage in the drainage cavity 55 can be completely drained, thus the sewage is not deposited in the impeller pump body 04, the risk that the sewage is easy to cause water quality deterioration and further generate peculiar smell due to long-time deposition is avoided, and further the washing device formed by the impeller pump body 04 is not polluted and the living environment is not influenced.

In impeller pump body 04 long-term work, filter screen 43 can filter sewage, avoid impurity to enter into the evacuation structure of below in to its inside water route cause the jam, ensure the evacuation structure can long-time normal work, and after filter screen 43 used for a long time, filter screen 43 surface can pile up impurity and influence its filter effect, and wash rack 46 follows pivot front end 47 and rotates, and then make wash rack 46 drive cleaning brush 45 rotate, cleaning brush 45 just can wash the impurity on the filter screen 43 down, and along with sewage is discharged from drain pipe 02, avoid impurity to pile up in the impeller pump inside.

The foregoing description of the preferred embodiment of the utility model is not intended to limit the utility model in any way, but rather to cover all modifications, equivalents, improvements and alternatives falling within the spirit and principles of the utility model.
