Abstract
A switching valve spool has a fixed shaft and a switching shaft coaxially arranged within. The switching shaft is linked with an operating unit and moves between a first, second, and third position in the fixed shaft along the axis. The switching shaft has an inlet and an outlet. In the first position of the switching shaft, the inlet is closed; in the second position of the switching shaft, the inlet is open and an air intake is formed between the side wall of the switching shaft closing to the outlet and the fixed shaft, when the water flows into the fixed shaft from the outlet, the air sucked from the air intake mixes with the water in the fixed shaft, because the fixed shaft diameter is larger than the outlet diameter; in the third position of the switching shaft, the inlet remains open and the air intake is closed.
