At the point where the cross-sectional area of the pipe in the air ejector suddenly decreases, a certain vacuum degree is formed, and the air at the inlet of the pump is sucked up by using the pressure difference between the vacuum degree and the atmospheric pressure to be discharged along with the directions from P (indicated by an arrow at the third connecting pipe) to B.
