The miniature water pump in the prior art is generally a diaphragm pump; the upper cover is provided with a water inlet needle that has been injection-molded with a metal needle for water inlet, and a water outlet passing through the upper cover is also provided on the side of the upper cover. There is a concave air dividing chamber around the water inlet and water outlet; there is a partition between the air dividing chamber and the water outlet, which is used to form a separate cavity for the water inlet and the water outlet; The liquid in the vacuum sealed container can be drawn out smoothly and there will be a siphon phenomenon after the liquid is discharged.

In the prior art, there is a micro-pump with an anti-siphon function of automatic air supply. Through the improvement of the structure, the air inlet needle and the water outlet needle of the upper cover are connected to the sealed container at the same time, so that the air inlet needle and the water outlet needle interact with each other. And the inside of the valve plate is provided with a stop valve and a spring device that communicate with the inside. The stop valve relies on the resistance of the spring, so that the stop valve structure set by the micro water pump can stop the siphon phenomenon and can reduce the siphon phenomenon.
