Claims

[Scope of utility model registration request]

An inner pipe whose lower end is in watertight contact with the valve seat provided between the water supply side pipe and the water discharge side pipe of the faucet body, and an inner pipe whose lower end is in watertight contact with the cylindrical upright part of the faucet body. An outer tube that is removably attached to the inner tube and a cap member that is removably attached to the upper end of the outer tube so as to cover the upper end of the outer tube in a watertight manner are integrally provided. The gap forms a bypass flow channel that communicates the water supply side pipe and the water discharge side pipe with each other, and the cap member is provided with a water flow control valve that adjusts the amount of water flowing through the bypass flow channel, and the water flow is adjusted. A valve chamber is provided in the bypass flow channel formed in the outer pipe on the downstream side of the valve, and a ball valve is disposed within the valve chamber, which normally closes the valve port communicating with the water discharge side pipe section by water pressure. At the same time, a push rod for pushing the ball valve to open the valve port is provided in the valve chamber so as to be movable back and forth, and the push rod is controlled by a motor controlled by a control mechanism having a non-contact type detector. A non-contact faucet that is driven via a reciprocating mechanism.
