Claim:
A miniature valve, comprising: a valve body and a driver positioned thereon; a supporting device; a valve seat provided with a first partition wall and defining a first channel and a second channel, the first channel and the second channel being separated by the first partition wall, the supporting device and the valve seat being connected and together defining a chamber therebetween; an elastic valve film, which comprises an elastic characteristic, set in the chamber and dividing the chamber into a liquid chamber and an installing chamber, and the valve film has a size configured to cover the first channel and the second channel and the first partition wall; and a rocker rotatablely positioned in the chamber via a shaft and having a force-receiving end and a first force-exerting end, wherein the first force-exerting end is configured to press against the valve film, the rocker is actuated at or between a first position and a second position, and when the rocker is at the first position, the first force-exerting end presses on a first portion of the valve film on only one side in stead of all sides of the first channel so as to cause at least the first portion of the valve film to separate the liquid chamber from communicating with the first channel by sealing off the only one side instead of the all sides of the first channel with the rocker; and when the rocker is actuated away from the first position, at least the first portion of the valve film is disengaged from the only one side instead of the all sides of the first channel to allow the first channel to communicate with the liquid chamber.
