A passage 203 is provided between the water inlet end 201 and the water outlet end 202, the passage 203 is used for generating negative pressure, the cross-sectional area of the passage 203 is smaller than that of the other positions of the negative pressure pipe 2, and thus, the cross-sectional area is suddenly increased at the position behind the passage 203, thereby generating negative pressure at the passage 203. The drainage tube 3 is communicated with the channel 203 through a residual water inlet end 204, and a water stop valve 4 is connected on the drainage tube 3 in series. When the residual water in the water storage chamber needs to be discharged, the water source 7 is opened, and after the water enters from the water inlet end 101 and flows through the channel 203, the residual water in the water storage chamber is sucked away under the driving of the negative pressure. In addition, the arranged water stop valve 4 can prevent water from leaking to the negative pressure pipe 2 from the flushing pipe 1 when the water inlet system works normally, so that water loss is caused. The water stop valve 4 is opened only when the residual water needs to be treated.
