An improved portable electrically powered leaf blower is disclosed that can provide levels of air flow and velocity comparable to those of gasoline-powered blowers, yet that generates substantially reduced noise, eliminates exhaust emissions and emissions from spilled fuel, and is lightweight and convenient to operate. The leaf blower incorporates a sound-insulated duct that encloses an electric motor and fan assembly, and a handle projects above the duct's inlet end. Electrical power is provided by a battery pack carried in a backpack worn by the operat...


[ We claim:] [31.] A blower apparatus, comprising:a duct having an inlet and an outlet;an electric motor located within the duct, between the inlet and the outlet, the motor including a rotatable shaft;a fan coupled to the shaft of the motor and configured to direct air along a flow path through the duct, from the inlet to the outlet;a handle projecting above the inlet of the duct and configured to be gripped by an operator; andan elongated support tube extending coaxially through at least a portion of the duct and configured to carry the motor, the fan,...
