Abstract

A solenoid valve includes a water inlet valve seat, a guide seat, a coil barrel, and a water outlet valve seat. When in an open state, an iron core is moved to close a pressure relief hole via an iron core spring and water pressure, and the diaphragm blocks the water flow of a water inlet via water pressure and the force of a guide spring, so as to achieve a bistable effect. The coil barrel includes two pairs of magnets and a pair of magnetically conductive sheets to form two magnetic routes. The solenoid valve has a simple structure and can be produced easily.

Abstract

A control valve of a manual/automatic and cold/hot water faucet includes a sliding member, a linking member, and an operating member. The sliding member has a notch. The linking member is recessed with a connecting groove. The operating member has a valve stem and a linking portion. The linking portion drives the linking portion and the sliding portion through the connecting groove. The valve stem, the connecting groove and the central axis are arranged concentrically, so that the overlapping area of the notch and the cold water hole is equal to the overlapping area of the notch and the hot water hole to keep the same ratio of cold water to hot water in an automatic mode to dispense water, thereby increasing the safety in use.

Abstract

A soap dispensing nozzle structure is mounted to a soap dispenser. The soap dispenser includes a soap bottle. The soap bottle is connected with a conveying member. The conveying member is connected with a dispensing member. The dispensing member has a dispensing opening. The dispensing opening is provided with a joint. The joint is connected with a soap dispensing nozzle. The soap dispensing nozzle includes a nozzle body. The nozzle body has a mounting portion, a body portion, and a reduced portion. The nozzle body has a passage therein. The passage has a pressuring hole. Thereby, through the reduced portion and the pressurizing hole, the force of discharging the liquid soap is strong, and it is not easy to remain excessive residual foam.

Abstract

A solenoid valve includes a coil housing, a coil barrel and an actuator. The coil barrel is mounted in the coil housing, is coiled with multiple coils, and has a valve gate formed on a bottom of the coil barrel. The actuator is moveably mounted in the coil barrel and has a piston, a magnetic shaft, a spring mounted between the piston and the magnetic shaft, and a sealing pad abutting the piston. The actuator is driven by the coils to move the piston. The piston has two notches being able to break a vacuum state, and can be pushed upward easily and efficiently to save electricity.

Abstract

The present invention recites a control method for a controller of a water faucet particularly for a battery operated water faucet. The method comprises the step to detect the change of back electromagnetic voltage in the driving circuit. The present invention also provides a control circuit of a controller for a water faucet particularly for a battery operated water faucet. The controller comprises a controller body having an electric solenoid formed therein, a sensor to emit and receive an Infrared signal so as to generate and transmit an operating signal, a microprocessor to receive and process the operating signal from the sensor, a driving circuit to control the switching ON-OFF of the solenoid, and a detecting means associated with a detecting circuit to detect the change of back electromagnetic voltage of the power applied to the solenoid so as to accurately control the water flow.

Abstract

A plunger-type diaphragm valve is disposed in an accommodation trough of a flush device. The accommodation trough communicates with an inlet passage and an outlet passage. The valve includes a control unit. One end of the control unit is provided with a diaphragm member and an engaging member, and another end leans against the outlet passage to block the inlet passage and the outlet passage. An outer wall of the diaphragm member is fixed to the accommodation trough. The diaphragm member has a curved portion. When the valve is actuated, the curved portion is deformed by water pressure to bring the control unit to move away from the inlet passage for the inlet passage to communicate with the outlet passage. The stressed area of the diaphragm member is small and the deformation is less, so the diaphragm member won't wear. The valve is durable and has a long life.
