As shown in fig. 7-9, the flow-regulating half-open state of the valve core of the adjustable flow switch is based on the working principle that: when the left-right rotation movable block 112 at the lower part of the rotor member 1 rotates left and right between the left blocking surface 251 and the right blocking surface 252 of the rotation limit stop 25 at the lower part of the stator member 2, the rotor water inlet 110 and the stator water inlet 23 are dislocated, and at this time, the area of the water inlet hole is gradually increased or decreased, so that the flow rate is also gradually increased or decreased.
