WIPO Patent Application WO2004010838

A3

A hand-held, battery-operated air blower is disclosed having a housing with a handle portion, a discharge end, an air inlet and a discharge aperture. A battery compartment is provided in the handle portion of the housing to contain one or more batteries. The battery compartment is electrically connected to a motor disposed within the housing between the battery compartment and the discharge aperture, transverse to the longitudinal axis of the housing. A centrifugal fan is mounted on the motor and positioned within the housing adjacent the air inlet in such a manner that operation of the fan draws air in through the air inlet and forces it out from the fan toward the discharge aperture then out through the discharge aperture. An actuator is provided for switching the flow of electricity from the batteries to turn the motor on and off.
