Self-closed anti-blocking water faucet

Abstract

The invention relates to a self-closed anti-blocking water faucet which is suitable for the old and children vulnerable groups and has small opening force when in use and has no need to open faucet dredging water-replenishing small holes after long-time usage; the self-closed anti-blocking water faucet comprises a three-way valve body, a valve core assembly is arranged in the valve body, the inner part of the valve core is separated into a water inlet chamber, a water outlet chamber and a control chamber by the valve core assembly, the valve core assembly is composed of a middle washer, a piston, a cylinder sleeve, a spring, a valve rod, a small O-shaped ring, a large washer, a small washer and a large O-shaped ring; a needle-shaped anti-blocking pin is arranged at the top part of the lower end of the valve rod, and the lower end of the anti-blocking pin enters the water-replenishing small holes below the piston; as the water faucet is opened only by applying force to overcome the friction force of the small O-shaped ring and the tensile force of the spring, therefore, the self-closed anti-blocking water faucet has the advantages of easy opening and labor saving; as the needle-shaped anti-blocking pin is arranged at the top part of the lower end of the valve rod, the anti-blocking pin can move up and down to dredge the water-replenishing small holes one time when the water faucet is opened one time, thereby no need of dredging the water-replenishing small holes by opening the water faucet after long-time usage and bringing great usage convenience to the old and children vulnerable groups.

Description

1. Technical field [0001] The invention relates to a water-saving faucet in daily life, in particular to a self-closing anti-clogging faucet. 2. Background technology [0002] In response to the government's call for saving water and establishing a water-saving society, a few months ago, I applied for a water supply that is suitable for public places and can be set according to the water supply conditions. A self-cleaning metered water supply faucet that is flushed with tap water and self-cleaning, thereby avoiding repeated infection of germs on the handle to the user. But this type of faucet exerts a lot of force when it is opened (requiring the user to tap upwards or lift the handle to open it), which is not suitable for the use of the elderly, children and vulnerable groups; When continuously flowing into the control chamber through the water supply hole, a small amount of impurities in the water will slowly adsorb on the side wall of the small hole after long-term use, ...

Problems solved by technology

But this type of faucet exerts a lot of force when it is opened (requiring the user to tap upwards or lift the handle to open it), which is not suitable for the use of the elderly, children and vulnerable groups; When continuously flowing into the control chamber through the water supply hole, a small amount of impurities in the water will slowly adsorb on the side wall of the small hole after long-term use, resulting in a gradual decrease in the flow cross-section and finally causing the small hole to be completely blocked, so the closing time of the faucet will decrease accordingly. At the end of the extension, there was a phenomenon that the faucet could not be turned off
