Abstract

A blower including a base having a housing, a handle extending from the housing, a power source positioned within the housing, the blower including: a drive shaft extending forwardly from the power source, wherein the drive shaft is rotatable by the power source; a fan member operatively connected to the drive shaft; a flywheel extending rearwardly from the power source, the flywheel being positioned adjacent to a rear of the housing; and at least one rear vent formed into the rear of the housing adjacent to the flywheel, wherein rotation of the flywheel draws ambient air into the housing through the at least one rear vent, and rotation of the flywheel generates a cooling air flow that directs the ambient air across the power source to cool the power source during operation thereof.

Claims

1. A blower that includes a base having a housing, a handle extending from said housing, a power source positioned within said housing, said blower comprising:

a drive shaft extending forwardly from said power source, wherein said drive shaft is rotatable by said power source;

a fan member operatively connected to said drive shaft, said fan member includes an axial fan;

a flywheel extending rearwardly from said power source, said flywheel being positioned adjacent to a rear of said housing; and

at least one rear vent formed into said rear of said housing adjacent to said flywheel;

wherein rotation of said flywheel draws ambient air into said housing through said at least one rear vent, and rotation of said flywheel generates a cooling air flow that directs said ambient air across said power source to cool said power source during operation thereof.

2. The blower of claim 1, wherein said flywheel includes a plurality of fan vanes.

3. The blower of claim 1, wherein said cooling air flow is further directed toward said fan member to increase air flow velocity produced by said fan member.

4. The blower of claim 1, said at least one rear vent including a plurality of rear vents, wherein air is drawn into said housing through said plurality of rear vents.

5. The blower of claim 1 further comprising a plurality of side vent formed into said housing and positioned between said power source and said fan member.

6. The blower of claim 5, wherein rotation of said fan member draws ambient air into said housing through said plurality of side vents.

7. The blower of claim 6, wherein said cooling air flow from said flywheel mixes with said ambient air entering through said side vents to increase a velocity of air flow generated by said fan member.

8. A blower that includes a base having a housing, a handle extending from said housing, a power source positioned within said housing, said blower comprising:

a drive shaft extending forwardly from said power source, wherein said power source selectively rotates said drive shaft;

a fan member operatively connected to said drive shaft, wherein said fan member includes an axial fan;

a starter assembly positioned adjacent to a rear of said housing;

a flywheel extending rearwardly from said power source, said flywheel being positioned between said power source and said starter assembly; and

at least one rear vent formed into said rear of said housing;

wherein rotation of said flywheel draws ambient air into said housing through said at least one rear vent, and rotation of said flywheel generates a cooling air flow that directs said ambient air across said power source to cool said power source during operation thereof.

9. The blower of claim 8, wherein said cooling air flow is further directed toward said fan member to increase air flow velocity produced by said fan member.

10. The blower of claim 8, said at least one rear vent including a plurality of rear vents, wherein air is drawn into said housing through said plurality of rear vents.

11. The blower of claim 8 further comprising a plurality of side vent formed into said housing and positioned between said power source and said fan member.

12. The blower of claim 11, wherein rotation of said fan member draws ambient air into said housing through said plurality of side vents.

13. The blower of claim 12, wherein said cooling air flow from said flywheel mixes with said ambient air entering through said side vents to increase a velocity of air flow generated by said fan member.

14. A blower comprising:

a base having a handle, a housing, and power source positioned within said housing, said power source having a drive shaft extending forwardly therefrom, wherein said power source selectively rotates said drive shaft;

a starter assembly positioned adjacent to a rear of said housing;

a flywheel positioned between said starter assembly and said power source;

a fan member having a first fan formed on one side thereof and a second fan formed on an opposing side thereof, said fan member being rotatably driven by said drive shaft;

a rear vent formed into a rear of said housing, wherein rotation of said flywheel draws ambient air into said housing through said rear vent;

a plurality of side vents formed into said housing and positioned between said power source and said fan member;

wherein rotation of said fan member draws ambient air into said housing through said plurality of side vents;

wherein rotation of said flywheel draws ambient air into said housing through said at least one rear vent, and rotation of said flywheel generates a cooling air flow that directs said ambient air across said power source to cool said power source during operation thereof;

wherein said cooling air flow from said flywheel mixes with said ambient air entering through said side vents to increase a velocity of air flow generated by said fan member.
