Abstract

A device which safely and conveniently vacuums up solid or liquid waste material of a hazardous or unpleasant nature, that includes a fluid reservoir for spraying, cutting and breaking up the waste and for lubricating and cleaning the hose and intake, intake and exhaust ports which are automatically sealed away after use, a waste receptacle which is sealed when not in use, venting of exhaust through filters to clean and deodorize, and a waste receptacle with automatically sealing removable bags.

Claims (30)

1. A wet-dry vacuum cleaning device for collection of solid, liquid or mixed matter comprising:
a fluid reservoir;
a pump in fluid communication with the fluid reservoir for pressurizing fluid in the fluid reservoir;
an intake for accepting the solid, liquid or mixed matter;
a waste receptacle to collect the solid, liquid or mixed matter;
a vacuum pump for providing suction to the intake and for collecting and moving the solid, liquid or mixed matter from outside of the nozzle into and through nozzle and into the waste receptacle;
a passageway connecting nozzle and waste receptacle;
a conduit to deliver fluid from the reservoir to at or near the intake;
a second conduit to deliver fluid from the reservoir to the interior of the passageway; and a filter for cleansing and deodorizing air received through the intake prior to venting the air to the atmosphere.
2. A device as in claim 1 wherein the waste receptacle includes a removable liner.
3. A device as in claim 2 wherein the removable liner is self-sealing.
4. A device as in claim 3 wherein the removable liner includes a neck portion, the neck portion including stiffeners which seal the removable liner when the neck portion is twisted.
5. A device as in claim 2 wherein the liner may be removed after being remotely sealed at the device operator's command thereby minimizing exposure of the operator to the liner's content(s).
6. A device as in claim 1 wherein the fluid is sufficiently pressurized such that when sprayed into the passageway there is sufficient volume of fluid for lubrication of the passageway to ease the passage of the solid, liquid or mixed matter therethrough to the receptacle.
7. A device as in claim 1 wherein the delivery of fluid to near the intake is controllable by the device's operator.
8. A device in claim 1 wherein the fluid is a cleaning agent.
9. A device in claim 1 wherein the fluid is a disinfecting agent.
10. A device in claim 1 wherein the solid or liquid matter targeted for pickup is animal feces.
11. A device in claim 1 wherein the solid or liquid matter targeted for pickup is toxic or dangerous waste.
12. A device in claim 6 wherein the fluid delivered near the intake at the device's operator's control is sprayed just ahead of the intake's effective range of suction.
13. A device in claim 1 wherein the motive power operating; the vacuum pump is electricity.
14. A device in claim 13 wherein the electricity is provided by on-board storage battery.
15. A device in claim 1 wherein the filter has activated charcoal as an element.
16. A device in claim 1 wherein the device is self-contained and human portable.
17. A device in claim 1 wherein the device is arrayed in components operatively connected and is vehicle-mounted.
18. A device in claim 10 wherein the animal feces is from household pets.
19. A device in claim 11 wherein the toxic or dangerous waste is from a medical facility.
20. A device in claim 11 wherein the toxic or dangerous waste is from an industrial process.
21. A device in claim 11 wherein the toxic or dangerous waste is from a chemical or other unintentional spill.
22. A device in claim 16 deployed like an upright vacuum cleaner or spray and-clean rug cleaner.
23. A device in claim 16 deployed in a hand-held unit.
24. A device in claim 1 wherein the intake is sealed from the environment when not in use.
25. A device in claim 24 wherein the intake sealing means includes means to deliver fluid from the reservoir to wash the intake during the sealing phase of its operational shut-down.
26. A device in claim 25 wherein during the sealing phase of its operation the passageways are also sprayed with fluid and thereby cleaned.
27. A device in claim 1 wherein the passageway includes a hose from the intake to the rest of the device when the intake is formed by a nozzle or attachment, and the nozzle or attachment is removed from but operatively connected to the device's main body and used remotely from the body of the device, as when using a hose-and-wand type of conventional wet-dry vacuum system.
28. A device in claim 1 wherein the exit air filter is replaceable.
29. A device in claim 1 wherein the exit-air vent is closed automatically during a shutdown procedure, thus sealing the receptacle from the device's environment when not in use.
30. A device in claim 1 wherein the device further includes a wheeled body to permit ease of movement by its operator.
