Problems solved by technology

[0002] At present, there are a large number of medical miniature solenoid valves (hereinafter referred to as solenoid valves) circulating on the market. The most commonly used ones are "diaphragm solenoid valve", "pinch valve", "non-isolation diaphragm valve" and so on. The required voltage (12V) is often greater than the required voltage for maintenance (5V), but in actual applications, if the starting voltage is used to provide the required voltage for maintenance, long-term work will reduce the life of the solenoid valve and increase the probability of unstable operation of the solenoid valve , increase the difficulty of electromagnetic compatibility, hidden dangers of electricity safety, increased energy consumption, etc.
Then how to overcome the disadvantages of energy consumption and electromagnetic incompatibility, this just needs those skilled in the art to solve corresponding technical problems

Abstract

The invention provides an electromagnetic valve control circuit with a low-power-consumption drive function. The electromagnetic valve control circuit comprises a low-power-consumption drive device, an electromagnetic valve, an MCU and a data sensor. The electromagnetic valve control terminal is connected with the signal output terminal of the low-power-consumption drive device, the signal input terminal of the low-power-consumption drive device is connected with the MCU control signal output terminal, and the MCU data interaction terminal is connected with the data sensor signal interaction terminal. State maintenance is conducted through low voltage ten-millisecond-level delay after the electromagnetic valve is started to work, and energy consumption required in the work process is lowered.
