## Background
RELATED APPLICATION
This application claims the benefit of U.S. Provisional Application No. 62/211,413 filed on Aug. 28, 2015.


FIELD OF THE INVENTION
The present invention relates to specific improvements in a power box for a backpack vacuum cleaning unit. In particular, the power box for a backpack vacuum can be worn by the user in an easy to access position, such as on a waist belt, thereby making access of the vacuum controls easier during the operation of the backpack vacuum.
SUMMARY OF THE INVENTION
The present invention is for the power box portion of a multi-piece vacuum, generally a backpack vacuum. In particular the present invention discloses a self-contained power box for providing the power to the backpack vacuum, and an optional power nozzle extension.
As shown in the drawings and described in detail below, according to the present invention a power box is provided with a recessed 3-prong male receiving outlet, a recessed female receptacle for an optional power nozzle hookup, and an on-off switch for controlling the power to the backpack vacuum.



BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1—Is a perspective view of the power box of the present invention.
FIG. 2—Is an elevational view of the power box of the present invention



DETAILED DESCRIPTION OF THE INVENTION WITH REFERENCE TO THE DRAWINGS
As shown in FIGS. 1 and 2, a vacuum power box (10) comprises a recessed power outlet (30) and recessed power nozzle hookup (20). The power outlet (30) comprising a male 3-prong attachment (31); and the power nozzle hookup (20) comprises twin female receptacles (21) for attaching an optional power nozzle.
In a typical backpack vacuum, a small power box is provided, that generally is fitted at or near the waist of the user, when the backpack vacuum is being worn for use. The vacuum portion is a backpack, and difficult to access, and thus a control box is generally provided for easy access to the controls.
The present invention maximizes the efficiency of the control box, by providing a multi-functional power box, with easy access to controls, adaptability, and minimal permanently attached wires. Further, the power connections on the power box (30 and 20) are recessed to allow for greater security, and reduce a user's need to worry about disconnecting or otherwise interfering with the wires while operating the vacuum. A shield is also provided at the top of each recessed connection, providing further security.
Any 3-prong extension cord can be used with the present invention, allowing versatile use in any setting, where any length chord may be needed. In some setting a very long cord (25-50 ft, and up) may be needed, and in others a cord that is only a few feet long is needed. The shielded and recessed cavity allows a secure hookup, that will not come undone easily while operating the machine, that is versatile to fit the need of whatever the setting requires.
Most backpack vacuum also come with an optional hookup for a power nozzle. The power nozzle allows backpack to be more versatile and attach a variety of extenders and attachments, which can act more like a standard, multi-function upright or canister vacuum wand. Similar to the above, the shielded and recessed cavity allows a secure hookup, that will not come undone easily while operating the machine, and allows for quick easy access and adaptation of the backpack for a variety of settings.
The power box contains a universal on/off switch (40) to control the power to the power box, and in turn the entire backpack vacuum.
