Sanitary Automatic Water Leakage Detection and Shut-Off Apparatus

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 comprising 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 activates the solenoid valve via an electronic communication method 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.
