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, the living standards of residents are constantly improving, and 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. The 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 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 judge whether overflow occurs based on changes in electrical signals, and send alarm signals to users or activate linkage equipment to cut off the water inlet. However, these methods can usually only deal with sudden large-scale water flow, but are difficult to detect minor leaks, and 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, which are easily affected by environmental interference and lead to misjudgment. In addition, most products do not have the ability to completely solve the problem from the source and can only issue warnings. Human intervention is still required to truly prevent further damage from occurring. Summary of the invention
