1. A hand-held air blower, comprising:
- a tubular housing having a cavity, an open end and peripheral air inlets spaced from said open end;
dividing wall in said housing cavity, said wall dividing said cavity into a rear closed compartment and a forward open compartment, said forward compartment including said open end and said peripheral air inlets;
a motor mounted in said forward compartment;
a fan mounted on said motor, said fan driven for rotation by said motor about the axis of said tubular housing, said fan mounted for drawing air into said forward compartment through said peripheral air inlets and for blowing the air out through said open end of said housing;
a power supply in said rear compartment, said power supply electrically connected to said motor;
wherein said dividing wall has a substantially frustoconical face directed toward said forward compartment, said face including a central disc-shaped surface perpendicular to the axis of said housing and a concave peripheral surface surrounding said disc-shaped surface, said concave peripheral surface aligned with said peripheral air inlets for guiding air from said peripheral air inlets to said fan.

Abstract
A hand-held blower includes a tubular housing having a cavity, an open end and peripheral air inlets spaced from the open end. A dividing wall in the housing cavity separates the cavity into a forward and a rear compartment, the forward compartment having a motor and a fan mounted on the motor, and the rear compartment having a rechargeable power supply electrically connected to the motor. Actuating means electrically connects and disconnects the rechargeable power supply and the motor and a charging jack electrically connected to the rechargeable power supply is provided for connecting the power supply to an external power source.
