The present invention proposes an air pump structure having driving effect. The present invention is characterized in that a swing element of the air pump is connected to a driving shaft. One end of the driving shaft has a poked part protruding out of a shell body of the air pump. Except having air-supplying function, the air pump of the present invention can drive a color disk or other devices of a water lamp. Another motor is not required for driving the color disk to rotate, thereby saving the cost of another motor. Moreover, the structure of the whole water lamp can be much simplified, resulting in convenience in assembly and reduction in cost.
