  Battery-powered spray wandUSPTO Application #: 20060013709Title: Battery-powered spray wand Abstract: A system, apparatus and method are provided for spraying liquid contained in a reservoir remote from said apparatus. The spray apparatus includes a housing in which a pump is positioned. The pump has an inlet and an outlet. An electric motor positioned within the housing drives the pump when a power supply located in the housing selectively provides power to the motor. A flexible intake hose connected to the inlet of the pump extends out of the housing to provide a path for liquid to flow from the remote reservoir to the pump. A discharge device in fluid communication with the outlet of the pump discharges liquid from the apparatus in a desired spray pattern. The housing also includes a hose compartment for storing a predetermined length of the intake hose when the apparatus is not in use so that the intake hose can be extracted from and inserted into the hose compartment. The spray apparatus may further include an extension for varying the distance between the discharge device and the housing. Additionally, a portion of the housing may pivot with respect to another portion of the housing. (end of abstract)

FIELD OF THE INVENTION [0001] The present invention relates to liquid sprayers, and more particularly to an improved battery-powered, hand-held spray wand used for convenient spraying of a desired liquid. BACKGROUND OF THE INVENTION [0002] Sprayers have long been used to spray liquids of various types, such as water, pesticides, herbicides and the like. Typically, conventional sprayers include at least a liquid container, a pump and a discharge device such as a spray nozzle. The pump is used to supply the pressure necessary to deliver the liquid from the liquid container to, for example, a hand-held wand assembly for application of the liquid. The significant shortcoming associated with these conventional devices is that considerable time and effort is often required to fill the liquid container prior to spraying. Additionally, the volume of the liquid container may be inadequate for the volume of liquid needed for larger spraying operations, thereby requiring refilling of the liquid container during the spraying operation. [0003] Accordingly, a need exists for a portable sprayer that allows for more convenient spraying of a desired liquid that is not limited by the size and location of the liquid reservoir. Additionally, there is a need for a portable sprayer that does not require filling of a liquid reservoir in the apparatus prior to and during spraying. SUMMARY OF THE INVENTION [0004] To overcome these and other disadvantages associated with known portable sprayers, a system, apparatus and method are provided for spraying liquid contained in a reservoir remote from said apparatus. The spray apparatus includes a housing in which a pump is positioned. The pump has an inlet and an outlet. An electric motor positioned within the housing drives the pump when a power supply located in the housing selectively provides power to the motor. A flexible intake hose connected to the inlet of the pump extends out of the housing to provide a path for liquid to flow from the remote reservoir to the pump. A discharge device in fluid communication with the outlet of the pump discharges liquid from the apparatus in a desired spray pattern. [0005] The housing also includes a hose compartment for storing a predetermined length of the intake hose when the apparatus is not in use so that the intake hose can be extracted from and inserted into the hose compartment. The spray apparatus may further include an extension for varying the distance between the discharge device and the housing. Additionally, a portion of the housing may pivot with respect to another portion of the housing. [0006] The foregoing specific objects and advantages of the invention are illustrative of those that can be achieved by the present invention and are not intended to be exhaustive or limiting of the possible advantages which can be realized. Thus, these and other objects and advantages of this invention will be apparent from the description herein or can be learned from practicing this invention, both as embodied herein or as modified in view of any variations which may be apparent to those skilled in the art. Accordingly, the present invention resides in the novel parts, constructions, arrangements, combinations and improvements herein shown and described. BRIEF DESCRIPTION OF THE DRAWINGS [0007] The accompanying figures best illustrate the details of the preferred apparatus, system and method of the present invention. Like reference numbers and designations in these figures refer to like elements. [0008] FIG. 1 is a detailed illustration of a spray apparatus in accordance with an embodiment of the present invention; [0009] FIG. 2 is a detailed illustration of a spray apparatus in accordance with another embodiment of the present invention; [0010] FIG. 3 is a detailed illustration of a spray apparatus in accordance with an embodiment of the present invention that includes a hose compartment; [0011] FIG. 4 is a detailed illustration of a spray apparatus in accordance with another embodiment of the present invention that includes a compartment; [0012] FIG. 5 illustrates a spray apparatus in accordance with an embodiment of the present invention that includes a portion that pivots with respect to the main body of the apparatus; [0013] FIG. 6 illustrates a spray apparatus in accordance with another embodiment of the present invention that includes a portion that pivots with respect to the main body of the apparatus; [0014] FIG. 7 is a detailed illustration of a spray apparatus in accordance with an embodiment of the present invention that includes an extension for increasing the distance between the discharge device and the main body of the apparatus; [0015] FIG. 8 illustrates a system using a spray apparatus in accordance with an embodiment of the present invention; and [0016] FIG. 9 illustrates a method of using a spray apparatus in accordance with an embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION [0017] FIG. 1 illustrates a spray apparatus or wand assembly 1 in accordance with an embodiment of the present invention. The main components of the spray apparatus or wand assembly 1 preferably include a power supply 2, motor 3, gear box or transmission 7, pump 9, intake hose 12, and spray or discharge device 11. The motor 3 preferably drives the transmission 7, which drives the pump 9. The power supply 2, motor 3, transmission 7 and pump 9 are preferably mounted within the main body or housing of the spray apparatus 1. [0018] The power supply 2 can be one or more rechargeable batteries, one-time disposable batteries, or battery packs. The power supply 2 should be of sufficient voltage to adequately supply power to the internal electrical components of the spray apparatus 1, such as the motor 3. By way of example, the power supply 2 can be any voltage between 1 and 12 volts DC. However, the voltage of the power supply 2 is in no way limited to these sizes and may vary depending on the size and power requirements of the spray apparatus 1. The power supply 2 is able to provide power to the internal components of the spray apparatus 1 (e.g., motor 3) by depressing an on/off switch 5, which closes the circuit between the power supply and the electrical components of the spray apparatus 1. A more detailed description of the communication between the on/off switch 5 and the electrical power circuit will be addressed in the figures that follow. [0019] Referring to FIG. 1, the intake hose 12 is preferably a flexible hose that is capable of being wound or folded as necessary. The intake hose 12 is preferably made from a flexible or pliable material such as, but in no way limited to, rubber, plastic or other similar material. One end of the intake hose 12 is connected to the pump 9 in a conventional manner and the intake hose exits the spray apparatus 1 proximate to the front of the spray apparatus 1 or proximal to the discharge device 11. Liquid passes through the intake hose 12 to the pump 9, where the pressurized liquid then passes through pump output conduit 10 for discharge by the discharge device 11. The pump output conduit is preferably made from a flexible or rigid hose, pipe or tubing that is connected to the pump in a conventional manner. The discharge device 11 is preferably a spray nozzle attached to the pump output conduit 10 in a conventional manner, such as by threading the nozzle onto the free end of the pump output conduit. The discharge device 11 is preferably capable of providing a fixed and/or variable spray pattern. Preferably, if a variable spray pattern is desired, the discharge device 11 can be rotated relative to the pump output conduit 10 to vary the spray pattern. Continue reading...
