Sanitary automatic water leakage detection and shut-off apparatus

摘要

The present invention provides a sanitary automatic water leakage detection and shut-off apparatus installed between a water controlling unit and a water outgoing unit and comprising a water controller, an accumulating unit and a detecting unit; wherein the water controlling unit comprises an inlet, an outlet and a solenoid valve. The solenoid valve is a normally-open solenoid valve capable of closing the outlet to stop water from going out. The accumulating unit is mounted between the water controlling unit and the water outgoing unit and comprises an accumulating hole adjacent to a bottom thereof. The detecting unit is installed on the accumulating unit and electrically connected to the solenoid valve. The detecting unit activates the solenoid valve via an electronic communication method based on a leakage status of the accumulating unit to shut off the water outlet of the water controlling unit and to stop water supply thereof immediately.

主权项

1. A sanitary automatic water leakage detection and shut-off apparatus, installed between a water controlling unit and a water outgoing unit, having a connecting unit between the water controlling unit and the water outgoing unit, the water shut-off apparatus comprising:
the water controlling unit including a water inlet, a water outlet and a solenoid valve between the water outlet and the water inlet; wherein the solenoid valve is a normally-open-type solenoid valve and is capable of closing the water outlet to stop water from going out; a water accumulating unit, provided between the water controlling unit and the water outgoing unit and completely enclosing the connecting unit, having a water accumulating hole adjacent to a bottom thereof; and a detecting unit, installed on the water accumulating hole of the water accumulating unit and electrically connected to the solenoid valve; wherein the detecting unit drives the solenoid valve in an electronic communication manner based on a leakage status of the water accumulating unit to shut off the water outlet of the water controlling unit and to stop water supply thereof.
