DEVICE FOR PREVENTING LEAKAGE FROM WATER PURIFIER

摘要

Disclosed is a device which prevents leakage by automatically shutting off flow of incoming tap water using a plunger as a check valve when a compressed pulp body expands due to fluid leaking from a water purifier or under a sink. The water leakage prevention device according to one embodiment of the present invention is installed in the flow path of running tap water to a water purifier, and comprises: a running water inlet connected to the water supply source; a running water outlet connected to the water purifier; an upper casing unit having a channel connecting the running water inlet to the running water outlet; a lower casing unit attached to the bottom of the upper casing unit and having a compressed body which expands with absorption of water leaking from the water purifier via the lower casing unit; and a plunger check valve which alternatively opens and closes the running water channel and prevents discharge of water through the running water outlet by closing said channel when absorption of leakage expands said compressed body.
