With the outlet direct intercommunication of inlet tube and washing basin, the drainage in washing basin can directly flow in the storage water tank, has saved manual process of pouring domestic wastewater into the storage water tank, and then has increased the utility model discloses a use convenience.

The apopore has been seted up in the diapire middle part of storage water tank, the entry and the apopore intercommunication of first check valve.

The outer diapire fixedly connected with install bin of storage water tank, first check valve, three way connection and second check valve all set up in the inner chamber of install bin, and the entry of the left end mouth of pipe of three way connection, second check valve all stretches out outside the install bin through the pipeline.

The outer bottom wall of the water storage tank is vertically provided with a plurality of supporting legs.

The filter is positioned right below the water inlet and is fixedly connected to the inner top wall of the water storage tank.

The water inlet is a circular water inlet with the diameter of 300 mm.

The utility model has the advantages of reasonable design reliably, realized domestic waste water reutilization's purpose, but domestic waste water's collection, discharge and overflow all can accomplish automatically moreover, need not manual operation, effectively improved the utility model discloses an use convenience, domestic waste water can effectively filter simultaneously, has avoided in the domestic waste water impurity to the influence of first check valve and second check valve, has that the structure is simple and easy, the practicality is strong, long service life's advantage.
