  • Patent number: 11608823
    Abstract: A micro pump is disclosed and includes a fluid-converging plate, a valve membrane, a fluid-outlet plate and a pump core module. The fluid-converging plate includes an inner recess, a protruding portion and a fluid-converging aperture. The protruding portion is disposed at a center of the inner recess. The valve membrane includes a valve aperture. The protruding portion of the fluid-converging plate abuts against the valve aperture. A fluid-converging chamber is formed between the valve membrane and the fluid-converging plate. The fluid-outlet plate in a ring shape includes a fluid-outlet channel. The valve aperture is in fluid communication with the fluid-outlet channel. When the fluid is inhaled into the pump core module, the fluid flows to the fluid-converging chamber through the fluid-converging aperture and then pushes out the valve membrane to flow into the fluid-outlet channel of the fluid-outlet plate through the valve aperture. Thereby the fluid transportation is achieved.
