摘要： A micro air delivery device for supplying air to a predetermined space, comprises a jet unit for obtaining and delivering outside air; a cover having a discharge orifice for discharging the outside air delivered from the jet unit; and a base unit connected to the jet unit. Since a valve is not employed to regulate the air supply or delivery, the air delivery device is superior in safety, is of simplified construction, and efficient. Furthermore, the air flow can be controlled by varying the electric current or the frequency, and accordingly, an active delivery of the air is possible.
