A wave generator including a base seat and an annular adjustment seat. A bottom face of the base seat is formed with a bubbling hole. Multiple sprinkling holes are formed along the circumference of the bubbling hole. The bottom edge of the adjustment seat is formed, with multiple downward extending parallel cleaning pins respectively corresponding to the sprinkling holes. When a user moves the base seat upward, permitting the water to flow out from the bubbling hole, the cleaning pins are respectively passed through the sprinkling holes to push out and clear off the dirt attaching to the wall faces of the sprinkling holes.
