Solution Overview
Problem
Existing electromagnetic valve structures are not stable enough, affecting the accuracy of fluid flow control due to an unreasonable intake structure.
Innovation Solution
A micro-flow valve control mechanism comprising an electromagnetic coil, a base, a ring seat, a moving plate, and an elastic plate, where the electromagnetic coil generates an upward attraction force and the elastic plate provides a downward elastic force, with a sealing ring ensuring tightness and precise control of the valve opening degree.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the electromagnetic valve uses a simple intake structure, then the device complexity is reduced, but the working stability deteriorates due to moving plate deflection
Solution Approach 1:
The patent introduces a ring seat as an intermediary component between the moving plate and the base. This ring seat serves as a guiding structure that constrains the moving plate's motion path, preventing lateral deflection while maintaining structural simplicity. The ring seat acts as a mediator that provides geometric constraints without adding complex control mechanisms.
2Ease of operation
If the moving plate is allowed to lift freely for air intake, then the ease of operation is improved, but the manufacturing precision deteriorates due to non-uniform air entry
Solution Approach 1:
The patent applies local quality by creating a specific geometric configuration where the ring seat's inner circumference defines a precise movement path for the moving plate. This localized geometric constraint ensures that air enters uniformly through the annular gap between the moving plate's outer ring and the ring seat, while still allowing the plate to lift freely for valve operation.
3Device complexity
If the valve opening degree is controlled without elastic force compensation, then the device complexity is reduced, but the measurement precision deteriorates in flow control accuracy
Solution Approach 1:
The patent implements self-service by using the elastic plate to automatically compensate for forces acting on the moving plate. The elastic plate generates restoring force that balances the air pressure and gravitational forces, allowing the valve to maintain precise opening degrees without requiring additional active control mechanisms. The system uses its own elastic components to self-regulate the control accuracy.

AI summary
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.
