Claims

[Claims for Utility Model Registration] (1) A water chamber is formed in the upper part of the case by a piston having a seal portion on the lower surface, and high pressure water from a water supply pipe is constantly flowed into the water chamber through a pinhole, and the pressure is adjusted to the water chamber. Therefore, the piston is energized to close the water supply outlet provided at the bottom of the case, and during use, the activation valve provided in the water drain hole at the bottom of the piston is opened and a certain amount of water is discharged from the water supply outlet, and then the water supply outlet is closed again. In the self-closing faucet that automatically closes the water supply outlet when the water chamber is filled with high-pressure water, a push rod opens the starting valve along the flow direction of the water supply of the discharge outlet main body connected to the lower part of the case. A self-closing faucet characterized in that a cam is disposed at the lower end of the push rod, and a lever for rotating a shaft supporting the cam is provided on the side of the discharge port body. (2) A case body consisting of a cylindrical body with a closed top end, a water supply pipe connected to a water supply inlet provided at the lower part of the side wall, and a water supply outlet at the bottom; It consists of a container body having a small diameter part facing the inlet, the small diameter part is provided with a pinhole that communicates with the inside and outside, and the bottom part has a seal part for opening and closing the water supply outlet, and forms a water chamber together with the inner wall of the upper part of the case main body. a piston that opens and closes a water drain hole provided at the bottom of the piston, and a discharge port body consisting of a cylindrical body with both ends open, the upper end of which is connected to the lower end of the case body, and the opposite end of which has a water supply and discharge port. and a push rod disposed along the water flow within the inner hole of the discharge port body to open the startup valve;
a cam follower attached to the lower end of the push rod; a cam attached to a shaft crossing the inner hole of the discharge port body and disposed in contact with the cam follower; and a cam coupled to the end of the shaft. A self-closing faucet consisting of a lever.
