A water storage jug with automatic water filling
By using a control valve structure that combines a float and a magnetic piston, the problem of unreliable water shut-off and easy contamination in water purifiers when the water storage device is full is solved, achieving the effect of automatic water shut-off and no leakage when the water is full.

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