Method and apparatus of driving multiple shafts in a wet/dry vacuum and liquid pump

Abstract

The present disclosure provides a method and system to supply pumping capabilities to a wet and dry vacuum cleaner. A single motor can operate a vacuum unit and the pump distinct from the vacuum unit. A port in the vacuum flow path can act as a vacuum tap to prime the pump when necessary. The pump can directly pump the fluids without having to flow first into the drum container of the vacuum cleaner. The system can allow independent operation of the vacuum unit and the pump and at different, more optimal speeds for each, allowing a higher performance on each of the vacuum unit and the pump, since maximum power for the system can be provided to either the operating device while the other one is not operating. Accordingly, the disclosure further provides a system and method for separately engaging and disengaging the vacuum unit and the pump.

Field of the Invention[0006]The invention relates to wet and dry vacuums. More specifically, the invention relates to wet and dry vacuums capable of pumping liquids.[0007]2. Description of Related Art[0008]Well known wet and dry vacuum cleaners can vacuum wet or dry materials into a container. Typically, a suction system with a motor creates a vacuum of pressure less than ambient pressure and is mounted in a lid that is removably attached to a collection drum for receiving the vacuumed materials. A portion of the lid extends downward into the drum and mounts a filter support assembly, such as commonly known as a “cage,” that covers a vacuum intake to the suction assembly in the lid. The suction system in the lid suc...

[0013]The present disclosure provides a method and system to supply pumping capabilities to a wet and dry vacuum cleaner. A single motor can operate a vacuum unit and the pump distinct from the vacuum unit. A port in the vacuum flow path can act as a vacuum tap to prime the pump when necessary. The pump can be arranged so it pumps fluids out of the drum or can directly pump the fluids without having to flow first into the drum container of the vacuum cleaner. The system can allow independent operation of the vacuum unit and the pump, and allow differen

Problems solved by technology

However, many locations, such as in a basement, do not facilitate easy draining.

The arrangement makes the disassembly and maintenance of the vacuum somewhat more complicated
