Problems solved by technology

[0002] Because the existing pulse solenoid valve controls the opening and closing of the valve port through the pulse electric signal, its working performance is stable, the trigger is fast, the power consumption is low, and the service life is long. It is more and more used in automatic control occasions, such as conventional induction Faucet, but the existing pulse solenoid valve requires a certain working pressure when it works, generally rated between 0.1-0.8MPa, because it is controlled by a small hole pilot, and the seal is realized by the pressure of the liquid in the pipeline. Open and close, so as to realize the opening and closing of the liquid in the pipeline controlled by the pulse solenoid valve, so when the existing pulse solenoid valve is used as the control part for the opening and closing of the liquid pipeline, the liquid in the pipeline needs a certain pressure to work normally, such as people Commonly used induction faucets controlled by pulse solenoid valves generally require the water pressure in the pipeline to be above 0.1MPa before the induction faucets can work normally. When people use bottled water, or other liquid beverages or liquid seasonings, etc. If the pressure is increased or pressurized by a liquid pump, the opening and closing of the liquid in the pipeline cannot be controlled by the existing pulse solenoid valve technology, that is to say, the pulse solenoid valve of the prior art cannot realize the liquid in the non-pressurized state. controlled
