ABSTRACT:
A type of multi-purpose photoelectronic automatic sensing faucet mechanism with single handle and water temperature regulation and water stop functions, an interior mechanism in faucets to be used in basin, shower tap and kitchen, comprising mainly of a piston rod fixing seat, a constant pressure water stop plate, a water output control valve, a temperature regulating and water stop turning shaft, a temperature regulating and water stop turning shaft fixing seat and a water inlet hole overflow check pad. Its water output is controlled by infra-red ray photoelectronic sensing switch solenoid, producing imbalance of water pressure in the solenoid, causing automatic control of water output, and coordinated with the design of single-handle temperature control and water stop function manual switch, to suit different user's requirement of temperature and convenient operation.
