ABSTRACT:
An air bubble generating apparatus has an air supplying device integrated with a pump. The air bubble generating apparatus comprises a pump for pumping water and for receiving a vacuum at a center portion thereof during pumping the water, a driving source for driving the pump, and an air supplying device for supplying air for the water by using an air pressure difference between the center portion in the vacuum state and an atmosphere. The air supplying device includes a hollow shaft through which the air flows, a first valve assembly adjacent to a first end of the hollow shaft and screwed in a bearing holder of the driving source, and a second valve assembly arranged at a second end of the hollow shaft. When the pump is operated so that a vacuum pressure is generated in the pump, the solenoid valve opens, so that there is a difference in pressure between the pump and the air supplying device. The ball valve of the air supplying device is opened by the difference in the pressure between the pump and the air supplying device, so that air is introduced into the pump and air bubbles are generated in pumped water.
