Abstract
Abstract An oral irrigation assembly of the type designed to be used in combination with a conventional water outlet such as an outlet associated with a showerhead or like water dispersement means. A water conduit includes a first and second channel structured to deliver water concurrently to the showerhead and to an assembly specifically structured to cause pulsing water flow to issue from the water conduit to an irrigating applicator preferably in the form of a nozzle or the like. A valve structure is disposed in water regulating relation to the second channel such that water flow may be selectively stopped when use of the oral irrigating device is not desired but water flow from the showerhead is maintained.

Claim 1
Independent Claim
304 words
An oral irrigating assembly of the type primarily designed for use with a substantially conventional water outlet, the assembly comprising: (a) conduit means secured to a conventional water supply and structured for delivery of water therefrom, (b) said water conduit means comprising a hollow interior portion including a first channel means extending along at least a portion of the length thereof and disposed for water delivery from the water supply to a delivery portion of said conduit means, (c) a second channel means formed within said hollow interior portion and structured and disposed for water delivery from the water supply to an exterior of said conduit means, said second channel means structured to define diverse paths of liquid flow therethrough, (d) water pulsing means movably mounted within said hollow interior portion in interruptive relation to said diverse paths of liquid flow, (e) said diverse paths of liquid flow comprising a first channel segment and a second channel segment at least partially disposed in spaced relation to one another and each structured to define a path of liquid flow from the water supply to said water pulsing means, (f) said second channel segment disposed to direct liquid flow into driving engagement with said water pulsing means, causing its rotation, said first channel segment disposed to direct water flow into flow regulating engagement with said water pulsing means, (g) said water pulsing means disposed in interruptive relation to liquid flow from said first channel segment and structured to alternately stop and pass said liquid flow beyond said water pulsing means, (h) said first and said second channel segments and said water pulsing means cooperatively disposed and struc tured to cause a pulsed liquid flow from said first channel segment concurrently to driving rotation of said water pulsing means by liquid flow from said second channel segment.
Claim 2
Dependent Claim
304 words
An oral irrigating assembly of the type primarily designed for use with a substantially conventional water outlet, the assembly comprising: (a) conduit means secured to a conventional water supply and structured for delivery of water therefrom, (b) said water conduit means comprising a hollow interior portion including a first channel means extending along at least a portion of the length thereof and disposed for water delivery from the water supply to a delivery portion of said conduit means, (c) a second channel means formed within said hollow interior portion and structured and disposed for water delivery from the water supply to an exterior of said conduit means, said second channel means structured to define diverse paths of liquid flow therethrough, (d) water pulsing means movably mounted within said hollow interior portion in interruptive relation to said diverse paths of liquid flow, (e) said diverse paths of liquid flow comprising a first channel segment and a second channel segment at least partially disposed in spaced relation to one another and each structured to define a path of liquid flow from the water supply to said water pulsing means, (f) said second channel segment disposed to direct liquid flow into driving engagement with said water pulsing means, causing its rotation, said first channel segment disposed to direct water flow into flow regulating engagement with said water pulsing means, (g) said water pulsing means disposed in interruptive relation to liquid flow from said first channel segment and structured to alternately stop and pass said liquid flow beyond said water pulsing means, (h) said first and said second channel segments and said water pulsing means cooperatively disposed and struc tured to cause a pulsed liquid flow from said first channel segment concurrently to driving rotation of said water pulsing means by liquid flow from said second channel segment.
Claim 3
Dependent Claim
24 words
An assembly as in claim 1 further comprising nozzle means interconnected in liquid communication to said water pulsing means and said second channel means.
Claim 4
Dependent Claim
47 words
An assembly as in claim 1 further comprising flow control means disposed in flow regulating position between a water supply and at least a portion of said second channel means, and structured to selectively stop water flow through at least a portion of said second channel means.
Claim 5
Dependent Claim
41 words
An assembly as in claim 3 wherein said flow control means comprises a valve structure at least partially disposed in water flow regulating relation between the water supply and said diverse paths of liquid flow and to said water pulsing means.
Claim 6
Dependent Claim
33 words
An assembly as in claim 1 wherein said second channel segment is disposed to direct liquid flow substantially tangentially of said water pulsing means and in interruptive, driving engagement with the periphery thereof.
Claim 7
Dependent Claim
41 words
An assembly as in claim 5 wherein said water pulsing means is rotatably mounted within said second channel means and comprises an outer periphery, structured and disposed for interruptive and rotatably driven contact by water flow through said second channel segment.
Claim 8
Dependent Claim
52 words
An assembly as in claim 6 wherein said pulsing means comprises a base portion structured to include said outer periphery formed thereabout; passage means formed in said base portion in substantially transverse relation to a plane of rotation of said base portion and in liquid communicating relation with said first channel segment.
Claim 9
Dependent Claim
31 words
An assembly as in claim 7 wherein said first channel segment defines a path of liquid flow from the water supply to said base portion and said passage means formed therein.
Claim 10
Dependent Claim
70 words
An assembly as in claim 8 wherein said passage means comprises a plurality of passage structures each spaced from one another and each extending through said base portion in transverse relation to a plane of rotation thereof, each of said passage structures successively positioned into fluid communicating relation with said first channel segment so as to successively direct liquid flow from said first channel segment through said water pulsing means.
Claim 11
Dependent Claim
50 words
An assembly as in claim 9 wherein said passage structures are integrally formed in said base portion to pass therethrough, said second channel segment and said passage means cooperatively disposed to define pulsing liquid flow through said base portion and direct said pulsing liquid flow exteriorly of said conduit means.
Claim 12
Dependent Claim
64 words
An assembly as in claim 6 wherein said first channel segment and said second channel segment are disposed in substantially common liquid communication with the water supply and structured to define separate and concurrent paths of water flow therefrom to said outer periphery and said passage means of said base portion respectively, whereby pulsing flow of water selectively issues from said water conduit means.
