    摘要： The present application discloses a micro-valve comprising: a first valve body and a second valve body, at least one of the first and second valve bodies defining a valve chamber and a valve seat, the first valve body having a liquid outlet and the second valve body having a liquid inlet; a valve plug disposed and movable within the valve chamber; and an elastic member disposed within the valve chamber and positioned closer to the liquid inlet than the valve plug. The elastic member has a liquid-inflow position and a liquid-outflow position, and in the liquid-inflow position, the elastic member enables liquid to flow from the liquid inlet through the elastic member to the liquid outlet, in the liquid-outflow position, the valve plug compresses the elastic member, such that the compressed elastic member seals the valve seat, or the compressed elastic member together with the valve plug seals the valve seat, so as to prevent liquid from flowing back from the liquid outlet to the liquid inlet through the valve seat.
