Abstract
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.
Claims31
A micro air delivery device comprising:
- a jet unit having a cavity to obtain and deliver outside air through a single orifice;
- 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 wherein the jet unit comprises:
- a jet plate having a plurality of orifices including the single orifice;
- a reservoir body disposed beneath the jet plate, and between the jet plate and the base unit;
- and
- a plurality of gaskets mounted along sides of the reservoir body;
- Wherein the plurality of orifices comprises:
- a jet orifice formed in the center of the jet plate and forming the single orifice;
- and
- a suction orifice formed at a predetermined distance from the jet orifice on the jet plate.
