Description:
TECHNICAL FIELD 
     The present invention relates generally to sanitation devices, and more particularly to a drain wand for cleaning floor drains. 
     BACKGROUND 
     The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. 
     Floor drains are installed in both commercial and residential structures where water is likely to accumulate. Most commonly, floor drains are installed at locations such as bathrooms and basements, for example, and function to prevent water from damaging the building structure. 
     In addition to the above, floor drains are also commonly located within commercial kitchens, and allow the floors to be easily rinsed and cleaned after food service has been completed. During the cleaning process, it is not uncommon for food particles and other gelatinous materials to pass through the drain grates, and to accumulate within the drain body. Over time, this accumulation of material can become a breeding ground for insects such as flies, gnats and roaches, for example. As a result, regular cleaning of floor drains is necessary to maintain a clean and safe environment. 
     In most instances, floor drains are cleaned by removing the screws that hold the drain grate in place, and then utilizing a pressure washer to clean the drain pipes. Unfortunately, these screws have a tendency to break or become stripped over time, thus preventing easy access to the drain body. Moreover, the utilization of high pressure water has two serious drawbacks. First, when high pressure water is sprayed into the drain, much of the offending material is splashed back out, into the surrounding area. When this occurs, the user must expend additional time and effort to clean the mess caused by the drain cleaning itself. Additionally, pressure washers have a typical output that is between 1,000 psi and 5,000 psi. When utilized on the plastic/PVC drains, this high pressure spray can easily crack the (often) brittle drain member. When a drain crack occurs, it then becomes necessary to hire a plumber or other such professional to repair the drain, thereby resulting in a large repair bill. 
     Accordingly, it would be beneficial to provide a drain wand that is specifically designed to clean building drains with a pressure that will not cause damage to the drain member, and that does not require a user to remove the drain grate. 
     SUMMARY OF THE INVENTION 
     The present invention is directed to a drain wand. One embodiment of the present invention can include an elongated wand body having a small diameter that can be positioned through the grate openings of a floor drain. The wand body can include a first end that houses a water inlet unit and a valve controller.

     DETAILED DESCRIPTION OF THE INVENTION 
     While the specification concludes with claims defining the features of the invention that are regarded as novel, it is believed that the invention will be better understood from a consideration of the description in conjunction with the drawings. As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention which can be embodied in various forms. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the inventive arrangements in virtually any appropriately detailed structure. Further, the terms and phrases used herein are not intended to be limiting but rather to provide an understandable description of the invention. 
     Identical reference numerals are used for like elements of the invention or elements of like function. For the sake of clarity, only those reference numerals are shown in the individual figures which are necessary for the description of the respective figure. For purposes of this description, the terms “upper,” “bottom,” “right,” “left,” “front,” “vertical,” “horizontal,” and derivatives thereof shall relate to the invention as oriented in  FIG. 1 . 
     As will be known to those of skill in the art, modern floor drains are typically constructed from plastic/PVC tubular members having a protective cover/grate secured along a top end. The grates typically include a plurality of openings that are at least ¼ inch in diameter, so as to allow water and other such material to easily pass into the drain body. Although described throughout this document as being utilized with a building floor drain, the inventive concepts disclosed herein are not to be construed as limiting to any particular use or field of endeavor. 
     Through extensive research and development, the inventor has discovered that a controlled discharge of water from a sprayer at approximately 125 psi impacting a plastic floor drain member at a distance of between 1 and 6 inches from the sprayer will function to dislodge accumulated drain material from the drain wall. Additionally, when the water impacts the drain wall at this pressure, there is not sufficient force to eject the material up, through the drain grate, and out of the drain body. Finally, repeated tests have shown that water sprayed at 125 psi does not have sufficient force to crack or otherwise damage existing floor drains. As such, the drain can repeatedly be cleaned at this pressure without risk of long term damage. 
     With this in mind,  FIGS. 1 and 2  illustrate one embodiment of a drain wand  10  that is useful for understanding the inventive concepts disclosed herein. As shown, the device  10  can include an elongated wand body  11 , having a sprayer  12 , a water inlet unit  13 , and a control handle  20 . 
     The wand body  11  can function as a hand held device that can pass through the openings in a drain grate, in order to spray water at a specified pressure into the building drain. In this regard, the wand  11  can include an elongated, generally hollow tubular member that is constructed from a rigid material such as steel, for example. In one embodiment, the wand body can include a generally blunt distal end  11   a  which can function, if necessary, to break up any clumps or large accumulation of undesirable material within the drain body. 
     A sprayer  12  can be disposed along the wand body at a location that is adjacent to the distal end  11   a . The sprayer can be connected to the proximal end of the wand  11   b  via an internal channel  11   c , and can function to disperse water laterally from the wand. 
     In the preferred embodiment, the wand body  11  can be constructed from a steel rod having a length of between approximately 24 and 36 inches, and an outside diameter of approximately ¼ inch. Likewise, the sprayer can include a single elongated aperture having a length of approximately ½ inches that is positioned longitudinally along the wand body at a location that is approximately 1 inch from the distal tip  11   a . The combination of the steel rod and the single aperture being sufficient to produce a lateral spray (i.e., perpendicular to the direction of the wand body) of approximately ½ inches and at a pressure of approximately 125 psi when secured to the buildings&#39; commercial water supply. 
     Although described above as including a specific construction material and/or dimension, other materials, shapes and sizes are also contemplated. Moreover, the sprayer  12  can also include any number of distinct openings, having any number of sizes and locations along the wand body so as to create a controlled discharge of water at a desired pressure. To this end, although 125 psi is the optimum output pressure, other pressures ranging from approximately 75 psi to 175 psi are also contemplated. Such pressures can allow the device to compensate for different types of water supplies which may be at various pressures from the spigot. 
     A water inlet unit  13  can function to connect the device to a water source. To this end, the inlet unit  13  can be positioned along the proximal end of the wand  11   b  and can be configured to mate with a conventional water hose (not shown) via the plurality of threaded grooves  13   a  imprinted on an inside portion thereof. In this manner, the inlet unit can function to receive water from the buildings water source and direct the same into the device via the internal channel  11   c . Of course, the device can be connected to any number of other types of water sources, and can also include other forms of connectors for engaging water supply lines, as are known in the art. 
     In one embodiment, the device can further include a control handle  20  which can act as a grip and controller for selectively engaging and disengaging the sprayer output. In one preferred embodiment, the control handle can be positioned along the proximal end of the wand body  11   b  at a location that is adjacent to the inlet unit  13 . As shown, the control handle  20  can include a trigger  21 , or other such mechanism, that is connected to a valve  21   a  that is capable of regulating the amount of water flowing through the internal channel  11   c.    
       FIGS. 3 and 4  illustrate one embodiment of the device  10  in operation. As shown, the wand body  11  can be positioned through any of the openings  5   a  of a floor drain grate  5  (see arrow A). When so positioned, the distal end  11   a  can be centered within the drain body  6 , and the sprayer  12  can be activated via the controller  20 . At this time, water W leaving the sprayer can be discharged laterally from the wand body and can impart the drain body at approximately 125 psi. This pressure being sufficient to dislodge any accumulated material M from the drain body. Next, the wand can be rotated 360 degrees (see arrow B) to clean all around the drain  6 , and can be raised and lowered (see arrow C) until the entire drain has been cleaned. 
     Accordingly, by utilizing the above described drain wand, a user can quickly and easily clean floor drains without causing damage to the drain body, and without splashing the offending materials up and out of the drain itself. 
     As described herein, one or more elements of the drain wand device  10  can be secured together utilizing any number of known attachment means such as, for example, screws, glue, compression fittings and welds, among others. Moreover, although the above embodiments have been described as including separate individual elements, the inventive concepts disclosed herein are not so limiting. To this end, one of skill in the art will recognize that one or more individual elements may be formed together as a single component, either through manufacturing processes, such as welding, casting, or molding, or through the use of a singular piece of material milled or machined with the aforementioned components forming identifiable sections thereof.
