Abstract: The present invention relates to a miniature valve, which includes a valve body comprising an inflow channel, an outflow channel and a liquid chamber, and a close assembly comprising a driver, a rocker and a valve film. The close assembly connects to the valve body and is configured to selectively close the inflow channel and the outflow channel. The rocker can be driven by the driver to move, so that the movement thereof acts on the valve film and makes the valve film selectively close the channel. The rocker and the valve film are separate components. The valve film, an elastic film locating in the liquid chamber, has a size configured to cover the inflow channel and the outflow channel. The miniature valve according to the present invention doesn't have interior dead area and has a slight effect on liquid fluctuation when switching channels.
