The liquid inlet pipe 112 has a flow passage, and the liquid inlet pipe 112 communicates with the throat pipe so that liquid flows through the liquid inlet pipe 112 into the venturi pipe 111.

The venturi tube 111 is in a shape of a honeycomb waist, has two large ends and a small middle, and consists of a contracted tube section, a throat pipe and a diffusion tube section, wherein the area at the throat pipe is the smallest. When medium flows through the venturi tube 111, the velocity is maximum at the throat, the static pressure is minimum, the throat pressure is smaller than the atmospheric pressure, the throat forms a "vacuum degree", and the vacuum degree is larger as the pressure difference is larger. The liquid inlet pipe 112 is communicated with the throat pipe, and liquid can flow into the throat pipe through the liquid inlet pipe 112 because the vacuum degree exists at the throat pipe.

The water in the water pipe flows into the venturi tube 111 through the inlet of the constriction tube section of the venturi tube 111. The flow velocity of the water gradually increases in the flow process of the contracted pipe section, the water reaches the maximum through the throat, and when the vacuum degree appears at the throat after the water flows out of the throat, the liquid is sucked into the throat through the liquid inlet pipe 112 and flows out of the venturi 111 together with the water flow.
