Patent attributes
A battery-powered portable personal fan is described with reference to two embodiments, both of which comprise a two-part base, of which the upper part is provided with an elongate neck to which a ball-shaped motor housing is pivotally attached. The motor housing contains a motor having a drive shaft which drives a two-blade at least 5000 RPM on a high-speed setting. In one embodiment, a rechargeable lithium ion battery is permanently mounted in the upper base portion and the lower base portion, available in multiple configurations is hollow so as to be useful as a storage area. It is preferably arranged so as to fit in one of several available golf cart cup holders. In the alternative embodiment, the lower housing is canister-shaped to receive a replaceable battery cartridge and, where desired, a tripod arrangement of legs for additional stability. Ornamental elastomeric covers can be stretched over the ball-shaped motor housing to visually link the fan to a particular sport.
