Benefits of technology

[0013] The present disclosure provides a method and system to adjust the outflow of exhaust air that flows out of a nozzle outlet attached to a removable vacuum unit of a wet and dry vacuum cleaner. This adjustment allows the vacuum unit to perform at full operating capacity in a vacuum mode and yet reduce the air flow in a blower mode with the vacuum unit operating as if in the vacuum mode. The nozzle can include an air diverter that allows air in the nozzle to be diverted away from nozzle outlet. The air diverter can be adjusted to a variety of positions for controlling the amount of air diversion. The nozzle can be removably coupled with the vacuum outlet using a latch. An inlet ring on the nozzle having an enclosed portion can engage the vacuum outlet on the vacuum unit and stabilize the nozzle coupling to the vacuum unit.

Problems solved by technology

While more flexible and more expensive, this version has disadvantages.
To obtain the necessary vacuum negative pressure to be commercially acceptable, the vacuum unit propels the outlet exhaust air through the vacuum outlet at such a force as to be difficult to use as a blower.
Reducing the motor speed results in acceptable blower performance, but unacceptable vacuum performance.
Further, the force is so great on the nozzle that the nozzle can become detached and “blown off” the vacuum unit.

Embodiment Construction

[0020] One or more illustrative embodiments of the concepts disclosed herein are presented below. Not all features of an actual implementation are described or shown in this application for the sake of clarity. It is understood that the development of an actual embodiment, numerous implementation-specific decisions must be made to achieve the developer's goals, such as compliance with system-related, business-related and other constraints, which vary by implementation and from time to time. While a developer's efforts might be complex and time-consuming, such efforts would be, nevertheless, a routine undertaking for those of ordinary skill in the art having benefit of this disclosure.

[0021]FIG. 1 is a schematic perspective view of an exemplary embodiment of the system. The exemplary system 2 is a wet and dry vacuum cleaner that generally includes a lid 4 coupled to a collection container 6. The lid is removably attachable to the container 6 so that the container can be emptied of d...

Description

CROSS REFERENCE TO RELATED APPLICATIONS [0001] Not applicable. STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT [0002] Not applicable. NAMES OF PARTIES TO A JOINT RESEARCH AGREEMENT [0003] Not applicable. REFERENCE TO APPENDIX [0004] Not applicable. BACKGROUND [0005] 1. Field of the Invention [0006] The invention relates to vacuum cleaners. More specifically, the invention relates to wet and dry vacuum cleaners having detachable blower nozzles for the vacuum cleaners. [0007] 2. Description of Related Art [0008] The use of wet and dry vacuum cleaners has become almost ubiquitous. Such devices are seen in most homes, businesses, and industrial facilities. Typically, the vacuum cleaner has a container for waste with a lid attached thereto. The lid houses the working components including the motor and vacuum impeller in a fixed orientation in the lid. A hose is attached to a vacuum inlet that allows debris to be vacuumed into the container. A port functioning as a vacuum ...
