DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference now to the drawings, and in particular to FIGS. 1 through 8 thereof, a new tank cleaning device embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.
As best illustrated in FIGS. 1 through 8, the recreational vehicle toilet tank cleaning assembly 10 generally comprises a tube 12 that has a terminal end 14. The tube 12 includes a plurality of sections 16 that are removably couplable to each other to alter a length of the tube 12. A valve 18 is mounted in one of the sections 16. The valve 18 selectively opens or closes the tube. The section 16 including the terminal end 14 is flexible in one embodiment shown in FIG. 8 or telescopic as shown in FIG. 7. In particular, the tube 12 may have length between 30 inches and 48 inches.
A nozzle 20 is removably coupled to the terminal end 14. The nozzle 20 has a first end 22, a second end 24 and a perimeter wall 26 extending between the first 22 and second 24 ends. The first end 22 is open and is threadably coupled to the terminal end 14 of the tube 12. The nozzle 20 has a plurality of apertures 27 therein. The apertures 27 include a primary aperture 28 that extends through the second end 24 and is aligned with a longitudinal axis of the nozzle 20. The plurality of apertures 27 includes a plurality of secondary apertures 30. The secondary apertures 30 are positioned in the perimeter wall 26 positioned nearer to the second end 24 than the first end 22 and are oriented perpendicular to the longitudinal axis. The plurality of apertures 27 includes a plurality of tertiary apertures 32 extending through the perimeter wall 26 and positioned between the second end 24 and the secondary apertures 30. The tertiary apertures 32 are each angled away from the first end 22. The perimeter wall 26 includes a tapered portion 34 tapering inward adjacent to the second end 24. The tapered portion 34 has the tertiary apertures 32 therein. The perimeter wall 26 has a break 36 therein and the nozzle 20 includes a first portion 38 rotatably coupled to a second portion 40. The second portion 40 includes the plurality of apertures 27.
A plurality of angled fins 42 is attached to an inner surface of the second portion 40. The fins 42 cause the second portion 40 to rotate with respect to the first portion 38 when a fluid flows through the tube 12 and outwardly of the nozzle 20. This causes the second portion 40 to spin and spray fluid in all directions within the receiving tank and may also be used for the tubing of the toilet system of the recreational vehicle.
In use, a distal end 44 of the tube 12 with respect to the terminal end 14 is fluidly couplable to a water source 46, with or without cleaning solution, and the nozzle 20 extended into the receptacle tank of a recreational vehicle's toilet system to eject water outwardly of the plurality of apertures 27 and clean the tank. The tube 12 may be extended throughout the tank to ensure thorough cleaning thereof. The distal end 44 may comprise any conventional male or female coupler used for fluidly coupling the tube 12 to the water source.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, 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 the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention 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 invention.
