ABSTRACT:
A cleaning device provided with a detergent control structure includes a tube, a connector, a control valve, and a handle. The tube is elongated and has a spray head and a cleaning element at a front end thereof. A rear end of the tube is connected to the handle provided with the control valve. The connector is internally divided into first and second channels and is coupled to a detergent box at a bottom end thereof. The control valve includes a securing block and a rotary block that are respectively provided with two round holes and a round hole. In use, the handle is connected to a water hose to allow input of water. By turning the handle to cause the round hole of the rotary block to align with the first round hole of the securing block and the first channel of the connector, clean water can be ejected from the spray head. If the handle is turned such that the round hole of the rotary block aligns with the second round hole of the securing block and the second channel of the connector, water is allowed to come into contact with the detergent in the detergent box so that a mixture of water and detergent can be ejected from the spray head to assist cleaning.
