ABSTRACT:
The present invention is directed towards an air circulation device. The air circulation device is capable of producing and directing an air current to a desired location. The air current is used to circulate stagnant air which, in turn, provides a cooling effect. Advantageously, the device is electrically powered by 12-volt direct current (DC) but is capable of producing an air current of a magnitude similar to or greater than that produced by air circulation devices which are powered by 120-volt alternating current (AC). Further, the device contains at least one retractable elongated support which allows the device to stand upright on a flat surface when the support is in an extended position. When the device is not in use, the support may be retracted so as to be protected from being damaged during transport. Still further, the device is manufactured of a polymeric material and the motor and bearings of the device are sealed. As a result, the device may be easily and safely cleaned using a liquid solution applied by a high pressure device such as a hose.
