Siphon spring 53 and anti-siphon rubber membrane 54 are constituted, and are provided with air inlet 51a and spillway hole 51b on anti-siphon lid 51；Work as electricity
When magnet valve internal pressure is greater than external pressure, anti-siphon rubber membrane 54 is in contact with anti-siphon lid 51 and forms sealing, in pass
Closed state；When solenoid valve internal pressure is less than external pressure, anti-siphon rubber membrane 54 compresses anti-siphon spring 53 and leaves anti-
Siphon lid 51 handles open state at this time, and air enters in solenoid valve from air inlet 51a makes pressure reach balance, prevents dirt
Water enters water inlet polluted source from water outlet suck-back, by solenoid valve, to realize anti-siphon function.Inside solenoid valve
When pressure is less than external pressure, while anti-siphon means 5 play a role, two sides vacuum breakdown device of vacuum 4 is opened simultaneously, is played
Synergistic effect, further improves every dirty effect.
When bath, the first scouring electromagnetic valve 31 or the second scouring electromagnetic valve 32 are powered and generate electromagnetic force, pull electromagnetism
The related seal plug of the dynamic iron core of valve moves upwards, to turn on relief hole 62a, the water in 2 cavity of valve deck is made to flow out pressure release,
Pressure becomes smaller, and sealing diaphragm 61 up moves from valve port under the promotion of intake pressure, makes water conduction, completes bath；Punching
After water, solenoid valve power-off, the related seal plug of the dynamic iron core of solenoid valve is moved downward, and withstands relief hole 62a, keeps water flow logical
It crosses pressurized hole 64 and enters 1 cavity of valve body, make the hydraulic pressure pressurization of the inside, push sealing diaphragm 61 to move downward, sealing valve port is closed
It closes.
The most preferred embodiment of the utility model has illustrated, the various change or remodeling made by those of ordinary skill in the art
All without departing from the scope of the utility model.
