Benefits of technology

This patent is about an actuator that can be controlled by coils. The valve gate is made part of the coil barrel and is supported by a sealing pad. This design increases strength and reduces the amount of space needed for the valve.

Problems solved by technology

A side wall of the coil barrel is located above the valve gate of the valve body, which occupies a space around the valve gate and badly affects the magnetic route of the piston in movement.
Due to manufacturing errors, an assembling gap is formed between the piston and the magnetic shaft and cannot be controlled at a constant value.
It will make the solenoid valve unstable in driving and increases the manufacture time and steps of process.

Embodiment Construction

[0024]With reference to FIG. 1 to FIG. 5, a solenoid valve of a preferred embodiment includes a coil housing 10, a coil barrel 20, an actuator 30 and a bottom cover 40.

[0025]The coil housing 10 is hollow, is cylindrical, and has a top surface, a bottom opening 11, an adjusting hole 12, a wire hole 13 and a magnet 14. The bottom opening 11 is formed in the bottom of the coil housing 10. The adjusting hole 12 and the wire hole 13 are formed in the top surface of the coil housing 10. The adjusting hole 12 is located at a center of the top surface of the coil housing 10. The wire hole 12 is located adjacent to a periphery of the top surface of the coil housing 10. The magnet 14 is a round disc, is mounted on the top surface of the coil housing 10, and has a tube hole 141 aligned axially with the adjusting hole 12.

[0026]The coil barrel 20 is mounted in the coil housing 10 and includes a shaft tube 21, an upper wall 22, a lower wall 23, a valve body 24, a coiling area 25 and a valve gate ...

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.

Description

BACKGROUND OF THE INVENTION1. Field of the Invention[0001]The present invention relates a solenoid valve, more particularly to a solenoid valve that improves the stability of operation, prolongs the service time and has efficient movement to save electricity.2. Description of Related Art[0002]The conventional automatic water flushers are installed in most public toilets because people increasingly care about the hygiene issue. Therefore, the sink faucet or the urinal tap in the public toilet adopts automatic water flushers to avoid contact with and spread of bacteria or virus.[0003]The conventional automatic water flusher includes a body sensor and a solenoid valve. The body sensor is used for detecting a human body or hand approaching by infrared rays. The solenoid valve includes a valve body and an electromagnet unit connected with the valve body.[0004]The valve body has an inlet port, an outlet tube and a valve gate connected between the inlet port and the outlet tube. The inlet ...
