Abstract

A cleaning, sanitizing or disinfecting scrubbing device includes a body, a non-thermal plasma generator and damp wipe. Generated plasma activates fluid in the wipe. The device may include spacer posts between the body and wipe and a conductive mesh between the body and wipe or embedded in the wipe. Another embodiment includes a reservoir for holding a water-based fluid, a fluid delivery element connected to the reservoir by a tube through which the fluid can flow and a non-thermal plasma generator. The non-thermal plasma generator activates the fluid. In one embodiment the scrubbing device is a mitt. In another embodiment the scrubbing device is a glove.

First claim

We claim:

1. A device to clean, sanitize, or disinfect a surface to be cleaned using a fluid that is converted to an antimicrobial fluid comprising:
a body configured to be movable by a person to clean a surface;
a reservoir for holding a fluid;
a fluid;
wherein the fluid comprises water;
a pump for pumping the fluid to the body;
an applicator on the body for applying the fluid to one of the surface and a wipes substrate;
a non-thermal plasma generator for generating non-thermal plasma; and
wherein the non-thermal plasma generator is configured to generate non-thermal plasma in contact with the fluid, wherein contact with the non-thermal plasma changes the fluid to an activated fluid that includes one or more reactive species.

2. The device of claim 1 wherein the body has a scrubbing surface, and wherein the scrubbing surface is a wipes substrate.

3. The device of claim 2 , wherein with the fluid is applied to the surface prior to the fluid being activated by non-thermal plasma.

4. The device of claim 1 wherein the fluid is applied to the surface after the fluid is activated by non-thermal plasma.

5. The device of claim 1 wherein the surface is moistened with the fluid prior to the fluid being activated by non-thermal plasma.

6. The device of claim 1 wherein the body is wearable by a user.

7. The device of claim 1 wherein the body is a mop.

8. The device of claim 1 wherein the body is a cleaning device having a rotatable head.

9. The device of claim 1 further comprising an array of spacer posts on the body, the array of spacer posts creating a space between the body and the surface to be cleaned.

10. The device of claim 9 further comprising a conductive mesh, wherein the conductive mesh is held between the body and the surface to be cleaned by the spacer posts.

11. The device of claim 1 wherein the body comprises a wipe and a conductive mesh.

12. The device of claim 1 further comprising a gas supply.

13. The device of claim 1 wherein the fluid comprises ethanol.

14. A device to clean, sanitize, or disinfect a surface to be cleaned using a fluid that is converted to an antimicrobial fluid comprising:
a body;
the body having a scrubbing surface, wherein the body is configured to be movable by a person to scrub a surface;
a non-thermal plasma generator for generating non-thermal plasma;
the non-thermal plasma generator comprising a high voltage electrode and a dielectric barrier; and
wherein the non-thermal plasma generator is configured to generate non-thermal plasma in contact with a fluid, wherein contact with the non-thermal plasma changes the fluid to an activated fluid that includes one or more reactive species; and
wherein the scrubbing surface is configured to be rubbed on the surface while the surface is contacted by the activated fluid having one or more reactive species.

15. The device of claim 14 further comprising a fluid reservoir in fluid communication with the body.

16. The device of claim 14 wherein the fluid is applied to the surface after the fluid is activated by non-thermal plasma.

17. The device of claim 14 wherein the fluid is applied to the surface prior to the fluid being activated by non-thermal plasma.

18. The device of claim 14 wherein the body is wearable by a user.

19. The device of claim 14 further comprising an array of spacer posts on the body, the array of spacer posts creating a space between the body and the surface to be cleaned.

20. The device of claim 14 further comprising a conductive mesh, wherein the conductive mesh is held between the body and the surface to be cleaned by the spacer posts.
