[0002] The dental suction machine is mainly used in conjunction with dental treatment equipment and is suitable for assisting dentists in the treatment of dental diseases. The impeller of the vortex air pump consists of dozens of blades, which is similar to the impeller of a huge gas turbine. When the impeller of the vortex air pump rotates, the air between the impeller blades is affected by the centrifugal force and moves toward the edge of the impeller. There, the air enters the annular cavity of the pump body again, and then returns to the impeller, and then circulates in the same way from the starting point of the blade. Because the air is accelerated by multiple cycles, the air leaves the air pump at a very high speed, thereby generating suction force.
