AI Technical Summary

Technical Problem

The existing micro diaphragm pumps have a small contact area due to the rubber gasket connection method, resulting in poor liquid delivery pressure and an inability to guarantee the overall liquid delivery pressure.

Method used

By employing a connecting push structure and support components, a motor drives the rubber pad to reciprocate within the mounting frame. Combined with the conveying structure and sealing frame, this increases the expansion effect of the rubber pad, ensuring high-pressure liquid delivery.

Benefits of technology

This achieves high-pressure liquid transport by increasing the propulsion force of the rubber pad, thus ensuring the overall transport pressure of the liquid.
