Abstract
The present disclosure discloses a micro-flow valve control mechanism, which comprises an electromagnetic coil, a base, a ring seat, a moving plate and an elastic plate; wherein the elastic plate is positioned above the base, the ring seat and the moving plate are positioned between the base and the elastic plate, the moving plate is positioned at the inner side of the ring seat. In this scheme, the structure of valve air intake control is optimized, and the ring seat plays the guiding role in the lifting of the moving plate to a certain extent, which ensures that the moving plate will not deflect in the air intake process, so that the outer ring at the lower side of the moving plate can allow air to enter uniformly, thus ensuring the working stability of the electromagnetic valve.
