Water leakage protection device for water purifier

Abstract

The invention relates to a water purifier leaking water interception protecting device. The device comprises an electric control module, a pressure maintaining valve arranged on a water inlet pipe of a water purifier, an interception magnetic induction mechanism and a water tank formed in the position, where water leakage is prone to occurring, in the water purifier. A leaking water sensor is arranged in the water tank. The pressure maintaining valve and the interception magnetic induction mechanism are integrally arranged. The pressure maintaining valve comprises a pressure maintaining valve water inlet pipe, a pressure maintaining valve body, a pressure maintaining valve water outlet pipe and a sliding part arranged in the pressure maintaining valve body. The interior of the pressure maintaining valve body is divided into a compression cavity and a water outlet cavity through the sliding part. Water outlets are formed in the sliding part and communicate with the pressure maintaining valve water outlet pipe. A first permanent magnet is arranged on the sliding part. The interception magnetic induction mechanism drives the sliding part to move so that the pressure maintaining valve water inlet pipe can be closed. The electric control module is electrically connected with the interception magnetic induction mechanism and the leaking water sensor.

Description

technical field [0001] The invention relates to a protection device for water leakage and interception of a water purifier. Background technique [0002] With the improvement of people's living standards and higher quality of life, water purification equipment has entered thousands of households, but the use of water purifiers has brought various troubles and worries to people. When people use the water purifier, there is water leakage from the water purifier. The water leakage of the water purifier is mainly divided into several parts, namely the water purifier outlet faucet, the water purifier filter element, the water purifier filter element base, and the bottom pipeline of the water purifier. Leakage of water purifiers is very dangerous for users. Many water purifiers use external power supply and the power cord is often located at the bottom, so the consequences of water purifier leakage are unimaginable. In addition, water leakage from the water purifier has a terribl...

AI Technical Summary

Problems solved by technology

Leakage of water purifiers is very dangerous for users. Many water purifiers use external power supply and the power cord is often located at the bottom, so the consequences of water purifier leakage are unimaginable

In addition, the leakage of the water purifier has a terrible impact on the floor furniture such as the kitchen and living room.

Water purifier leakage is a waste of resources

[0003] Publication No. CN105204535A discloses a device for effectively controlling the water leakage of the water purifier. Its disadvantages are: a tray needs to be installed under the water purifier, which takes up space and affects the aesthetics. There is a lot of water leakage and it takes a while to find it, and the hysteresis is obvious , and only has a single sensor, there is no water leakage prompt, and the location of the water leakage cannot be clearly defined

Publication number CN202379762U discloses a water purifier water leakage protection device. Its disadvantages are: external power supply is required and the water leakage is judged by the internal pressure change of the water purifier, and the error is large. The water pressure of high-rise residential areas varies greatly in a day and it is not known where the water leaks.
