The water inlet pipe of the shunt valve body assembly is used for being connected with an external water source, the first water spraying channel is connected with the spray gun to form a flow path, and a water outlet hole is formed in the spray gun at the tail end of the flow path. Because only one water outlet is formed, the water pressure is higher when water is discharged from the water outlet, and therefore the flow path is mainly used for relaxing the bowels. The second water spraying channel is connected with the spray gun to form another flow path, the spray gun is provided with two water outlet holes at the tail end of the flow path, and the water pressure of the two water outlet holes is relatively low when water is discharged. The flow path is therefore primarily used for hip washing.

Therefore, the working states of the valve are divided into three types: 1. the first water outlet channel and the first water spraying channel have an overlapped area, the first water outlet channel and the second water spraying channel have no overlapped area, at the moment, the first water spraying channel can spray water, and the valve is in a defaecation working state. 2.
