AI Technical Summary

Technical Problem

Existing water purifiers and their associated water storage devices have problems such as unreliable water shut-off after being full and susceptibility to contamination.

Method used

The control valve structure uses a combination of a float and a magnetic piston. When the water is full, the float rises and drives the magnetic block to disengage from the magnetic piston, automatically closing the control valve and cutting off the water supply when the water is full. A one-way valve structure also prevents leakage.

Benefits of technology

It achieves reliable automatic water shut-off when the water tank is full, preventing secondary pollution and avoiding leakage. It automatically shuts off the water supply when the tank is full without leaking.
