Illustratively, the evacuation line 5 communicates with the main conduit 2 via a tee fitting 7.

In the technical scheme, the three-way joint can be directly selected from the existing structure, and the main pipe 2 and the emptying pipeline 5 are matched with the existing structure, so that the structure is simple, and the assembly and the production are convenient; wherein, three way connection sets up as close to house steward bottom as possible, does benefit to the row of raffinate, even a little raffinate can't be arranged, also can't produce destructive influence.

Illustratively, a normally open solenoid valve 8 is disposed within the evacuation conduit 5.

In the technical scheme, the electromagnetic valve is connected with a control device of the spraying device, when the spraying device works, the electromagnetic valve is electrified, the valve is closed, the liquid flow and the water pressure of the spraying device are prevented from being influenced, and the nozzle works normally in a spraying mode; when the spraying device stops working, the electromagnetic valve also opens the valve due to power loss, at the moment, the residual pressurized liquid in the main pipe and the branch pipe can be instantly released into the liquid storage barrel through the emptying pipeline and the opened electromagnetic valve, so that the nozzle loses water pressure and stops dripping, thereby avoiding waste, reducing pollution, and also avoiding the main pipe, the branch pipe, the nozzle and the like from being corroded or damaged by icing and bursting.
