Blower/vacuum
A blower/vacuum being interchangeable between a blower configuration and a vacuum configuration is provided. The blower/vacuum includes a blower assembly attachable to a base in the blower configuration and a vacuum assembly attachable to the base in the vacuum configuration. The blower/vacuum includes a fan member that has both a first fan and a second fan integrally formed together, wherein the first fan is utilized to generate air flow in the blower configuration and the second fan is utilized to generate air flow in the vacuum configuration.
1. 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 therefrom, wherein said drive shaft is rotatable by said power source;
a fan member having a central hub, a frustoconical surface and an outer circumferential edge, the fan member including a first fan having a plurality of first fan blades, wherein said plurality of first fan blades extend outwardly beyond said outer circumferential edge, said fan member being rotatable by said drive shaft;
a blower assembly selectively attached to said base, wherein said blower assembly includes a blower housing attachable to said base, a diffuser positioned adjacent to said fan member, and a blower tube attachable to said blower housing and extending therefrom;
wherein said diffuser includes an elongated cone having an open end and a diameter, a platform surrounding and extending radially outward from said open end, and a plurality of vanes extending from said platform.
2. The blower of claim 1 , wherein said first fan provides positive-pressure air flow to cause air to be blown axially through said blower assembly.
3. The blower of claim 1 , wherein said blower housing is formed of a non-clear or non-transparent material.
4. The blower of claim 1 , wherein said blower housing is formed of a clear or transparent material.
5. The blower of claim 4 , wherein said blower housing is formed of clear polycarbonate or clear plastic.
6. The blower of claim 1 , wherein said attachment of said blower assembly to said attachment shell creates a substantially spherical casing.
7. The blower of claim 6 , wherein said spherical casing is transparent.
8. The blower of claim 1 , wherein said plurality of first fan blades extend outwardly beyond said circumferential outer edge of said frustoconical surface in a cantilevered manner.
9. The blower of claim 8 , wherein said plurality of first fan blades are angled with respect to said frustoconical surface.
10. The blower of claim 1 , wherein said plurality of first fan blades are angled or curved relative to said central hub.
11. The blower of claim 1 , wherein said plurality of first fan blades generates an air flow that is substantially parallel to said drive shaft.
12. The blower of claim 1 , wherein said fan member further includes a second fan.
13. 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 therefrom, wherein said drive shaft is rotatable by said power source;
a fan member including a first fan, said fan member being rotatable by said drive shaft;
a blower assembly selectively attached to said base,
wherein said blower assembly includes a blower housing attachable to said base, a diffuser positioned adjacent to said fan member, and a blower tube attachable to said blower housing and extending therefrom, and
wherein said diffuser includes an elongated cone having an edge defining an open end and a diameter, a platform surrounding and extending radially outward from said edge, and a plurality of vanes extending from said platform.
14. The blower of claim 13 , wherein said diameter of said elongated cone narrows as it extends away from said open end.
15. The blower of claim 13 , wherein said blower housing includes an air flow path with a narrowing diameter for increasing air flow velocity over said diffuser.
16. The blower of claim 13 , wherein said fan member further includes a second fan and wherein said open end of said cone receives and completely surrounds said second fan.
