Abstract

The invention relates to a faucet, in particular to a water cut-off self-closing faucet which comprises a faucet body, a handle, a water inlet pipe and a water outlet pipe. The water inlet pipe is arranged at the left side of the handle and provided with a water cut-off self-closing device; the water cut-off self-closing device consists of a set casing, a valve pin, a valve core, a return spring I, a water baffle plate, a water guide sleeve, a push rod, an end cover and an elastic rubber cover. The invention has the advantages that the water inlet pipe of the invention can be sealed when the faucet is opened but no water flows out; when the pipeline is supplied with water, if the user forgets to close the handle of the faucet, water can not enter into the faucet body; if needing water, the pipeline waterway can be communicated with the faucet body by invalidating the water cut-off self-closing device.

Description

technical field [0001] The invention relates to a water tap, in particular to a self-closing water tap. Background technique [0002] Common faucets in the prior art, when people open the faucet and find that there is no water, they often forget to close the faucet.
