Description

Technical Field

[0001] The present application relates to the technical field of water leakage protection equipment, and in particular to a water leakage protector. Background Art

[0002] With the acceleration of urbanization and the continuous improvement of residents' living standards, people are paying more and more attention to home safety. In modern life, water pipe leakage caused by various reasons has become one of the important factors threatening people's quality of life and causing economic losses. Existing water leakage monitoring and control systems mostly use a single sensor or manually shut off the water source, which has many limitations in sensitivity, timeliness and intelligence.

[0003] Common leakage prevention measures currently available on the market mainly include mechanical valves (such as float valves), electronic level gauges and pressure gauges. Among them, mechanical valves use water flow to push the internal structure to achieve automatic shut-off function; while electronic level gauges use electrical signal changes to determine whether overflow has occurred, and send alarm signals to users or activate linkage equipment to cut off the water supply. However, these methods can usually only deal with sudden large-scale water flow, but are difficult to detect minor leaks. In addition, they lack remote control capabilities and cannot meet the needs of modern smart homes.

[0004] Although there are some relatively advanced water leak alarm products on the market, most of them rely on the working status of a single sensing point to make decisions and are easily affected by environmental interference and misjudgments. In addition, most products do not have the ability to completely solve the problem at the source and can only issue warnings. Human intervention is still required to truly prevent further damage. Summary of the Invention
