But nowadays, the ecological environment has been severely damaged, and the water body is seriously polluted. The protection of water resources and the control of water pollution have become the most concerned issues in modern society. my country is one of the 13 water-poor countries in the world, and its fresh water resources are less than 1/4 of the world's per capita water volume. Among the more than 600 cities in the country, more than 400 cities have insufficient water supply. Among them, 110 cities have serious water shortages, and the total water shortage in cities across the country is 6 billion cubic meters. Water-saving action is urgent.

In real life, especially in a collective living environment like a school, the faucets we use usually only have one gear position. Although the amount of water can be controlled by the rotation angle of the valve switch, in general, we Always habitually open the valve to the maximum, so as to cause unnecessary waste; when there is a sudden water cut-off, for example, some schools will turn off the water supply after the lights are turned off, so that the students who are using water will forget to turn off the water after the water is cut off Water tap, when water is supplied again, water will flow out constantly and cause a lot of waste. The traditional water faucet, because the switch is not well positioned and there is no auxiliary positioning device, water drips and leaks occur from time to time after the faucet is turned off.
