The invention discloses a toilet stool water-saving system, which comprises a flushing tank, a drain pipe, a toilet stool and an S-shaped bent pipe. A drain valve is mounted at the bottom of the flushing tank, and one end of the drain pipe is communicated with the bottom of the drain valve. The S-shaped bent pipe comprises a first straight pipe, an arc-shaped water storage pipe and a second straight pipe which are connected in sequence. The first straight pipe is connected to the drain pipe, the second straight pipe is horizontally arranged and connected to a flushing water inlet of the toiletstool, and the height difference between the lower edge of the outer wall of the second straight pipe and the lowest position of the outer wall of the arc-shaped water storage pipe is larger than theouter diameter of the S-shaped bent pipe. External air is isolated through the S-shaped bent pipe from communicating with a water inlet of the drain pipe through a toilet stool water pipeline, when the drain valve drains water, due to the fact that the air pressure in the drain pipeline is smaller than the air pressure of outside air, water can be stored in the drain pipeline in advance after thedrain pipeline is flushed each time, the pre-stored water can directly act on next flushing, the stroke of the water is saved, kinetic energy loss of water flow in the conduction process is reduced,and the flushing effect is greatly improved.
本发明公开了一种便器节水系统，包括冲水箱、排水管、便器和S弯管，冲水箱的底部安装有排水阀，排水管的一端与所述排水阀的底部相连通。S弯管包括顺序相连的第一直管、弧形存水管和第二直管。第一直管与所述排水管相连，第二直管水平设置并与所述便器的冲洗进水口相连，第二直管的外壁下沿与所述弧形存水管的外壁最低处的高度差大于S弯管的外径。本发明通过S弯管隔离了外界空气通过便器通水管道与排水管进水口相连通，排水阀排水时，由于排水管道内的气压小于外界空气气压，因此排水管管道每次冲完水后都会预存有水，预存水可以直接作用于下一次冲洗，节省了水的冲程，降低了水流在传导过程中的动能损失，大大提高了冲洗效果。
