ABSTRACT:
A spraying gun includes a water inlet connector, a connecting member, an adjusting member, a detergent tube, a water conducting tube, and an extension pipe. Thus, the water flow rate of the spraying gun is adjusted by rotation of the adjusting member, thereby facilitating a user regulating the water flow rate of the spraying gun. In addition, the water is mixed with the detergent by rotation of the adjusting member to provide a cleaning effect.
