An anti-run water faucet

Abstract

A water running preventing faucet comprises a faucet body and a water running preventing mechanism. The faucet body comprises a valve, a valve element, a rotary switch, an upper end cover and a bottom cover. The water running preventing mechanism comprises a piston assembly and a shifting fork assembly. The piston assembly comprises a piston and a first spring. A water inlet hole sealing cap is arranged at the lower end of the piston. A piston chamber is formed in the lower end of the valve element. The first spring and the piston are arranged in the piston chamber. One end of the first spring abuts against the valve element, and the other end of the first spring abuts against the piston. The shifting fork assembly comprises three shifting forks, a second spring and a spring pin. The three shifting forks are fixed to the outer wall of the lower end of the valve element at equal intervals in the circumferential direction, and the three shifting forks and the valve element are of an integrated structure. A spring chamber is formed in the inner wall of the valve, and the second spring is arranged in the spring chamber. One end of the spring pin is inserted in the spring chamber, the other end of the spring pin abuts against the valve element, and a push rod is obliquely arranged on the spring pin. According to the water running preventing faucet, a water inlet of the faucet can be automatically sealed, water running is prevented, the structure is novel, and using is convenient.

Description

technical field [0001] The invention relates to a water faucet, in particular to an anti-running water faucet capable of preventing water from flowing out even if the water faucet is turned on after the water is cut off and the water comes in again even if the water is forgotten to be turned off. Background technique [0002] At present, the known common faucets cannot be automatically closed in the case of forgetting to turn off the faucet when the water is cut off, so that it is impossible to prevent secondary hazards caused by water overflowing the pool when the water comes again; at present, some faucets can only be closed regularly by pressing the faucet switch To achieve water saving, but this kind of faucet does not consider the water consumption of each person. Generally, the user needs to press the switch several times to make the water meet the demand, which makes it inconvenient for the user to use, that is, the human-machine efficiency is low; Although there is n...

Problems solved by technology

[0002] At present, the known common faucets cannot be automatically closed when the water is stopped and they forget to turn off the faucet, so that it is impossible to prevent secondary hazards caused by water overflowing the pool when the water comes again; at present, some faucets can only be closed regularly by pressing the faucet switch To achieve water saving, but this kind of faucet does not consider the water consumption of each person. Generally, the user needs to press the switch several times to make the water meet the demand, which makes the user inconvenient to use, that is, the human-machine efficiency is low; Although there is no such problem in the induction faucet, the cost is too high to be widely promoted, and there are safety hazards such as electric leakage.

At present, although there are a few faucets that can theoretically realize the anti-running water function, most of them adopt the floating ball principle, which has poor controllability and low reliability.
