Abstract
The inventive pump structure comprises a base, a motor, pump vanes and a top cap. The pump vanes are disposed on the base and sleeved on the rotation shaft of the motor. On top of the pump vanes are disposed several fan-shaped blades and each fan-shaped blade has the same area with each other. On each fan-shaped blade are formed several indentation regions and each indentation region has the same area with each other. The area of each indentation region is the same as the area of each fan-shaped blade, thus, after the liquid flows in, by using the motor drives the pump vanes to rotate, the liquid is extruded and then ejected from the outlet because of the centrifugal force.
