Abstract

Insertion of a dust wand into a portable vacuum filtration canister removes foreign matter therefrom when and where necessary without polluting the air. A powerpack provides cordless (rechargeable or non-rechargeable) and corded operation. A readily serviceable grid filter, and a HEPA or other filter provides cleaned air free of dirt, dust and allergens.

Claims

1. A dust wand cleaning appliance, comprising:

first means for receiving at least a portion of a dust wand to be cleaned; and

second means for removing foreign matter from a dust wand received by said receiving means.

2. The dust wand cleaning appliance of claim 1, wherein said first means includes a canister having a chamber adapted to receive a dust wand and said second means includes a motor driven fan, a filter and a power module operatively connected to said motor driven fan.

3. The dust wand cleaning appliance of claim 2, wherein said motor driven fan and said power module are mounted in said canister.

4. The dust wand cleaning appliance of claim 3, wherein said filter is mounted in a drawer slidably mounted to said canister.

5. The dust wand cleaning appliance of claim 4, wherein said filter is a grid filter.

6. The dust wand cleaning appliance of claim 5, wherein said grid filter is a mesh filter.

7. The dust wand cleaning appliance of claim 4, wherein said filter is a HEPA filter.

8. The dust wand cleaning appliance of claim 2, wherein said motor driven and said power module are mounted in a housing releasably mounted to said canister.

9. The dust wand cleaning appliance of claim 8, wherein said filter is releasably mounted to said canister at the interface between said canister and said housing.

10. The dust wand cleaning appliance of claim 9, wherein said filter is a mesh filter.

11. The dust wand cleaning appliance of claim 8, wherein said filter is mounted to said housing.

12. The dust wand cleaning appliance of claim 11, wherein said filter is a HEPA filter.

13. The dust wand cleaning appliance of claim 2, wherein said power module includes an AC adapter.

14. The dust wand cleaning appliance of claim 2, wherein said power module includes rechargeable batteries.

15. The dust wand cleaning appliance of claim 2, wherein said power module includes non-rechargeable batteries.

16. The dust wand cleaning appliance of claim 2, wherein said canister is provided by mating, interfitting first and second housing bodies and wherein a baffle cooperates with at least one of said first and second housing bodies to provide said chamber.

17. The dust wand cleaning appliance of claim 16, wherein said second means includes a vacuum annulus in communication with a portion of said chamber and an annular comb/dust agitation ring extending circumferentially radially inwardly about said vacuum annulus to provide mechanical agitation of a dust wand received in said chamber.

18. The dust wand cleaning appliance of claim 2, wherein said canister is provided by mating, interfitting first and second housing bodies and wherein a dust wand receiving sleeve is mounted to said first and second housing bodies to provide said chamber.

19. The dust wand cleaning appliance of claim 18, wherein said dust wand receiving sleeve is circumferentially slotted about a portion of its length and said second means includes a wire comb/dust agitation ring mounted in said sleeve about said circumferentially slotted portion thereof to provide mechanical agitation of a dust wand received in said chamber.

20. The dust wand cleaning appliance of claim 2, wherein said second means further includes a switch.

21. The dust wand cleaning appliance of claim 20, wherein said switch is a manually actuated switch.

22. The dust wand cleaning appliance of claim 20, wherein said switch is automatically actuated upon insertion of a dust wand in said chamber.

23. The dust wand cleaning appliance of claim 22, wherein said automatically actuated switch includes an infrared emitter and detector.

24. The dust wand cleaning appliance of claim 2, wherein said motor driven is mounted to said cannister and said power module is mounted in a housing releasably mounted to said canister.

25. A dust wand cleaning appliance comprising:

a canister having an open mouth in communication with an internal chamber adapted to receive a dust wand; and

a particulate removal system including an air inlet, an air outlet, a flow passage, a filter and a motor driven vacuum impeller blade so arranged as to draw air through the air inlet past at least a portion of the internal chamber where it entrains any foreign matter that may be present on a dust wand received in the internal chamber and to move the air along the flow passage and into the filter which separates out entrained foreign matter and discharges purified air cleaned of foreign matter through the air outlet.
