At the same time, with the continuous rotation of the rotating rod 502, the control rotating plate 11 also rotates, and when the control rotating plate 11 rotates to a certain angle, the control rotating plate 11 also hinders the flow speed of the liquid or gas, so as to further adjust the flow speed of the gas or liquid.
