ABSTRACT:
The water flow control structure of a water gun includes a movable control tube, stepwise positioning unit, oblique guide and resilient component. When the control tube is moved by the control component, it is turned by the oblique guide and stepwise positioning unit. Each time the first guide of the control tube coordinates with the position of the stepwise positioning unit, it makes the space between the stopper head of the control tube and the water control outlet of the water holder close or open in different degrees to control water flow. The entire control structure is hidden inside the water gun. The repeated movements of the control component can switch the water flow mode, which is convenient and practical.
