Abstract

A vacuum accessory tool that includes a nozzle body having a first end and a second, spaced apart end and at least one light emitting element that emits light that will illuminate a surface to be cleaned by the accessory tool is described. The light emitting element is protected by a protective housing that protects the element when the tool is inserted into areas during cleaning, yet still allows the light to illuminate surfaces during operation.

Claims

1. An attachment tool for a vacuum cleaner operable as a crevice tool, the attachment tool comprising:

an attachment end adapted for mounting to a vacuum cleaner;

a nozzle end spaced apart from the attachment end;

a nozzle body intermediate between the attachment end and the nozzle end and defining an exterior of the tool, the nozzle body comprising a lower housing region proximate the nozzle and an upper housing region comprising a first, upper body region proximate the air conduit and a second, intermediate body region intermediate the upper housing region and the lower housing region; and

a light assembly comprising a housing containing at least one light emitting element that emits light in a UV or visible spectrum and that will illuminate a surface to be cleaned, the light assembly being mounted on a leading, forward end of the nozzle body,

wherein the nozzle end is tapered downward and away from the nozzle body.

2. The attachment tool of claim 1, wherein the lower housing region is tapered downward and away from the nozzle body.

3. The attachment tool of claim 2, wherein the lower housing region is tapered at an angle ranging from about 130°

to about 170°

relative to a horizontal axis of the attachment tool.

4. The attachment tool of claim 1, wherein the at least one light emitting element is at least one light emitting diode (LED).

5. The attachment tool of claim 1, wherein the at least one light emitting element further comprises a convex lens to disperse light illuminated from the at least one light emitting element.

6. The attachment tool of claim 1, further comprising a power switch mounted within the light assembly for powering the at least one light emitting element.

7. The attachment tool of claim 1, wherein the housing of the light assembly has a U-shape.

8. The attachment tool of claim 1, wherein the first upper body region has a circular cross section.

9. The attachment tool of claim 1, wherein the lower housing region has an oval cross section.

10. The attachment tool of claim 1, wherein the nozzle body is formed of a plastic material by blow molding.

11. A tool, comprising:

a main body having a first end including a suction inlet, a second end including a discharge outlet, and an internal air path;

a receiving region on a top face of the main body sized to receive an illumination assembly; and

an illumination assembly, the illumination assembly including a cover and a light emitting element,

wherein the suction inlet is in fluid communication with the discharge outlet and the tool includes a longitudinal centerline axis A.

12. The tool of claim 11, wherein the first end of the main body is tapered toward the first suction inlet and the taper is offset from the longitudinal centerline axis A.

13. The tool of claim 12, wherein the offset taper is offset at an angle ranging from about 110°

to about 165°

relative to the longitudinal centerline axis A.

14. The tool of claim 11, wherein the second end of the main body has a circular cross section.

15. A vacuum cleaner system comprising:

a housing;

a debris collection vessel;

a vacuum suction generator;

a cleaning hose connected to the suction generator; and

a crevice tool including;

a main body having a first end including a suction inlet, a second end including a discharge outlet, an internal air path, and a longitudinal centerline axis A;

a nozzle body intermediate between the suction inlet and the discharge outlet, the nozzle body comprising a lower housing region proximate the suction inlet and an upper housing region comprising a first, upper body region proximate the discharge outlet and a second, intermediate body region intermediate the upper housing region and the lower housing region; and

a light assembly comprising a light housing containing at least one light emitting element that will illuminate a surface to be cleaned, the light assembly being mounted on a leading, forward end of the intermediate body region,

wherein the lower housing region is tapered downward and away from the nozzle body.

16. The system of claim 15, wherein the lower housing region is tapered downward at an angle ranging from about 110°

to about 165°

relative to the longitudinal centerline axis A.

17. The system of claim 16, wherein the angle ranges from about 130°

to about 160°

relative to the longitudinal centerline axis A.

18. The system of claim 15, wherein the discharge outlet has a circular cross section.
