Valve core with microporous structure and solenoid valve using valve core

A solenoid valve using a valve core with a microporous structure, comprising a valve body, an electromagnetic component, an elastic component and a valve core;

• the valve core comprises a sealing component and a microporous material, wherein the sealing component is located at an upper end of the microporous material, and the sealing component seals a top of the microporous material;
• the microporous material is a flexible material with a microporous structure that allows fluid to pass through;
• the valve core is arranged in the valve body, the elastic component is arranged between the valve core and the electromagnetic component, a flow channel is arranged on the valve body, and the microporous material is matched with a flow channel on the valve body;
• when the electromagnetic component is not energized, the elastic component presses the valve core, such that the microporous material is in a compressed state, and the microporous material seals the flow channel on the valve body;
• when the electromagnetic component is energized, the valve core overcomes the elastic force of the elastic component to release the microporous material, allowing the flow channel on the valve body to be open;
• and
• the electromagnetic component changes a compression amount of the microporous material by varying a magnitude of a magnetic attraction force, thereby controlling the flow rate of the flow channel on the valve body.
