Abstract

An electrostatic hand cleansing apparatus is disclosed. The electrostatic hand cleansing apparatus may be configured to expose a hand to cleansing substances, remove at least one contaminant therefrom, ameliorate the presence of at least one undesirable agent thereon, or combinations thereof. The electrostatic hand cleansing apparatus may include at least one electrostatic spray nozzle having an emission tip configured to emit an atomized, electrically charged substance. Further, a collection structure may be configured with a recess to collect a substance emitted from the at least one electrostatic spray nozzle. The collection structure may include an aperture formed therein for removing gas therethrough from the recess thereof. A sensor configured to indicate the presence of at least one hand proximate the at least one electrostatic spray nozzle is disclosed. The sensor may be configured to measure a contamination characteristic of a hand proximate thereto. A method of use is also disclosed.

Claims

2. The cleansing apparatus of claim 1, further comprising a sensor configured to indicate the presence of at least one hand positioned generally between the at least one electrostatic spray nozzle and the collection structure.

3. The cleansing apparatus of claim 2, wherein the sensor comprises a photoelectric sensor configured to indicate the presence of at least one hand generally between the at least one electrostatic spray nozzle and the collection structure.

4. The cleansing apparatus of claim 1, wherein the at least one electrostatic spray nozzle emission tip is positioned in relation to the collection structure within about two times of the depth of the recess thereof.

5. The cleansing apparatus of claim 1, wherein the recess of the collection structure comprises a partial generally hemispherical recess.

6. The cleansing apparatus of claim 5, wherein the at least one electrostatic spray nozzle emission tip is positioned in relation to the collection structure within about two times the depth of the recess thereof.

7. The cleansing apparatus of claim 1, wherein the collection structure is configured to selectively electrically attract or repel the atomized, electrically charged substance emitted from the at least one electrostatic spray nozzle.

8. The cleansing apparatus of claim 7, wherein the collection structure comprises an electrical insulator.

9. The cleansing apparatus of claim 1, further comprising a grounding element for electrically grounding the user.

10. The cleansing apparatus of claim 9, wherein the grounding element is configured to indirectly release from the user.

11. The cleansing apparatus of claim 10, wherein the grounding element is configured as a U-shaped band sized and configured to engage a portion of the user.

12. The cleansing apparatus of claim 9, wherein the grounding element is electrically connected to a grounding mat.

13. The cleansing apparatus of claim 12, wherein the grounding element is configured for attaching to a shoe of the user.

14. The cleansing apparatus of claim 1, further comprising a hood sized and configured to influence the distribution of the atomized, electrically charged substance emitted from the at least one electrostatic spray nozzle.

15. The cleansing apparatus of claim 14, wherein the hood is configured to electrically influence the atomized, electrically charged substance emitted from the at least one electrostatic spray nozzle.

16. The cleansing apparatus of claim 1, wherein the at least one electrostatic spray nozzle comprises a plurality of electrostatic spray nozzles.

17. The cleansing apparatus of claim 1, further comprising an aperture formed within the collection structure.

18. The cleansing apparatus of claim 17, wherein the aperture is sized and configured for drawing gas therethrough from within the recess of the collection structure.

19. The cleansing apparatus of claim 18, wherein the aperture is sized and configured for drawing gas therethrough from within the recess of the collection structure in relation to an expected distribution of the atomized, electrically charged substance emission from the at least one electrostatic spray nozzle so as to substantially capture the emission from the at least one electrostatic spray nozzle by way of the collection structure.

20. A method of cleansing at least one hand, comprising:

providing at least one electrostatic spray nozzle having an emission tip;

providing a collection structure having a recess including a depth;

disposing the collection structure generally oppositely to an expected direction of emission of the at least one electrostatic spray nozzle;

sensing the presence of at least one hand generally between the at least one electrostatic spray nozzle and the collection structure recess;

exposing the at least one hand to at least one electrically charged substance emitted from the at least one electrostatic spray nozzle.

21. The method of claim 20, wherein exposing the at least one hand to at least one electrically charged substance emitted from the at least one electrostatic spray nozzle comprises removing at least one contaminant from the at least one hand.

22. The method of claim 20, wherein providing a collection structure disposed generally oppositely to the expected direction of emission of the at least one electrostatic spray nozzle comprises configuring the collection structure so that the at least one electrostatic spray nozzle emission tip is positioned in relation to the collection structure within about two times of the depth of the recess thereof.

23. The method of claim 20, wherein exposing the at least one hand to at least one electrically charged substance emitted from the at least one electrostatic spray nozzle comprises causing at least one undesirable agent to become substantially innocuous.

24. The method of claim 20, further comprising drawing gas from the recess of the collection structure.

25. The method of claim 20, further comprising altering an electrical characteristic of the collection structure so as to attract or repel the at least one electrically charged substance emitted from the at least one electrostatic spray nozzle.

26. The method of claim 25, wherein altering the electrical characteristic of the collection structure comprises electrically grounding the collection structure.

27. The method of claim 20, further comprising altering an electrical characteristic of the at least one hand so as to attract or repel the at least one electrically charged substance emitted from the at least one electrostatic spray nozzle.

28. The method of claim 27, wherein altering the electrical characteristic of the at least one hand comprises electrically grounding the at least one hand.

29. The method of claim 20, wherein exposing the at least one hand to at least one electrically charged substance emitted from the at least one electrostatic spray nozzle comprises exposing the at least one hand to a first electrically charged substance and exposing the at least one hand to a second electrically charged substance.

30. The method of claim 29, further comprising electrically charging the first and second electrically charged substances differently.

31. The method of claim 20, wherein:
