The first wheel 46 is positioned on the first lateral wall 24 of the housing 12 adjacent to the rear wall 22, and the second wheel 48 is positioned on the second lateral wall 26 of the housing 12 adjacent to the rear wall 22. The first wheel 46 and the second wheel 48 have a common rotational axis. An extendable handle 50 is slidably coupled to the rear wall 22 of the housing 12 such that the extendable handle 50 is extendable upwardly from the housing 12.
A nozzle 52 is fluidly coupled to a distal end 54 of the supply hose 34 with respect to the pump 32 for dispensing the fluid 30 from the nozzle 52. A fluid level gauge 56 is in fluid communication with the tank 28 to indicate a level of the fluid 30 within the tank 28. The fluid level gauge 56 is mounted on the housing 12 and includes an indicator dial 58 facing outwardly away from the housing 12. The fluid level gauge 56 is electrically coupled to the control circuit 36 such that the control circuit 36 deactivates the pump 32 when the fluid level gauge 56 indicates that the tank 28 is empty. The fluid level gauge 56 may include a float 60 which is buoyant in the fluid 30 such that it remains near a top surface of the fluid 30 in the tank 28. In such an embodiment, the float 60 is operatively coupled to the indicator dial 58 to indicate a level of fluid 30 contained in the tank 28 and operatively coupled to the control circuit 36 to deactivate the pump 32 when the tank 28 is empty of the fluid 30.
A lid 64 is removably positioned on the housing 12 to cover the interior space 18. A top handle 66 is coupled to and extends upwardly from the lid 64. An inlet tube 68 is fluidly coupled to the tank 28 and is positioned on a top side 70 of the tank 28 such that the tank 28 is fillable via the inlet tube 68. An inlet cap 72 is removably coupled to the inlet tube 68 to selectively close the inlet tube 68. An outlet tube 74 for draining the tank 28 through the outlet tube 74 is fluidly coupled to the tank 28 and is positioned on a rear side 76 of the tank 28 adjacent to a bottom side 78 of the tank 28. The outlet tube 74 extends through the perimeter wall 16 of the housing 12. The outlet tube 74 is externally threaded and is shaped such that the outlet tube 74 may fluidly couple to a garden hose. An outlet cap 80 is removably coupled to the outlet tube 74 to selectively close the outlet tube 74.
A light emitter 82 is coupled to the housing 12 and is positioned on the perimeter wall 16. The light emitter 82 is electrically coupled to the control circuit 36 and is directed to emit light away from the housing 12. A power supply 84 is electrically coupled to the control circuit 36 and is positioned within the interior space 18. The power supply 84 comprises a battery 86. A plurality of electrical outlets 88 is electrically coupled to the control circuit 36 and is positioned on the perimeter wall 16 of the housing 12. A power inverter 90 is electrically coupled to the control circuit 36 for converting direct current electrical power supplied by the power supply 84 into an alternating current electrical power supplied to each electrical outlet 88 of the plurality of electrical outlets 88. The power inverter 90 is also positioned within the interior space 18.
An input 92 is electrically coupled to the control circuit 36 and is positioned on the perimeter wall 16 of the housing 12. The input 92 includes a power switch 94 for selectively supplying electrical power to the plurality of electrical outlets 88, a pump switch 96 for selectively activating the pump 32, and a light switch 98 for selectively activating the light emitter 82. A charging cord 100 for charging the battery 86 is electrically coupled to the control circuit 36 and is coupled to the perimeter wall 16. The charging cord 100 is configured for electrically coupling to an alternating current power source. A cord mount 102 is coupled to the perimeter wall 16 of the housing 12 which comprises a plurality of radially positioned hooks 104 upon which the charging cord 100 is wound. A charging port 106 is electrically coupled to the control circuit 36 and is coupled to the perimeter wall 16. The charging port 106 is configured for receiving electrical power from a direct current power source. A direct current cord 108 is stored in the interior space 18 and is couplable to the charging port 106.
In use, the tank 28 is filled with the fluid 30. The system 10 may be moved to a location where a user 110 desires to spray the fluid 30 by carrying the system 10 with the first and second carrying handles 42 and 44, rolling the system 10 on a surface via the first and second wheels 46 and 48 while grasping the extendable handle 50, or a combination thereof. The supply hose 34 may be unwound from the reel 38 to reach areas the user 110 desires to spray. The pump 32 is activated and the user 110 directs the supply hose 34 toward the desired areas. The fluid 30 may be water, a washing fluid 30 containing soap, a solvent, a surfactant, or the like, or any fluid 30 the user 110 desires to spray. The system 10 may be used, for example, to water plants, wash a car 112 or boat, and the like.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
