ABSTRACT:
A personal air cooling apparatus includes a main housing having a hollow interior that houses a water-retaining sponge in a first chamber and a motor-driven fan in a second chamber. A partition wall separates the chambers and is apertured so that air pulled into the first chamber flows through the sponge and through the aperture into an air passageway that leads to an air outlet vent that directs a strong flow of cooled air onto the user. The first chamber has a depth less than a depth of the sponge so that an empty space is provided between the partition wall and the sponge. The empty space facilitates flow of ambient air through the sponge and reduces the load on the motor. The personal air cooling apparatus is compact and light-in-weight so that it can be carried by a user.
