Referring in detail to the drawings, and more particularly to FIGS. 1 through 9 of the drawings, the numeral 10 indicates the faucet and plumbing attachment of the present invention which is adapted to be connected to a conventional unit or faucet 11 that may be provided with the usual control knob or handle 12, FIG. 1. As shown in FIG. 1, one or more of the faucets 11 may be arranged over a conventional sink 13 that may have the usual drain 14 therein.
The device 10 of the present invention includes a hollow housing 18 that has a hollow interior 19, and the housing 18 includes first and second spaced parallel side walls 15 and 16 that may be of circular formation, and the housing 18 further includes an arcuate end wall member 17 that is interposed between the walls 15 and 16.
Secured to or formed integral with the upper portion of the housing 18 is a fitting 20 that has a passageway 21 therein that communicates with the interior 19 of the housing 18, FIG. 3. The fitting 20 may include a reduced diameter portion 22 that is threaded externally for threadedly engaging the inner threaded portion of the faucet 11, as shown in the drawings. A screen 23 may be mounted in the fitting 20, and the screen 23 can be held in place by a snap ring or snap fastener 24.
Mounted in the housing 18 and extending between the pair of side walls 15 and 16 is a shaft 25, FIG. 2, and a rotor 26 is rotatably mounted on the shaft 25 within the housing 18. The rotor 26 includes a central hub 27 as well as a plurality of radially disposed blades 28 that may be suitably affixed to the hub 27, and the blades 28 may have a slightly curved or arcuate formation, as shown in the drawings. The numeral 29 indicates a spring member that is circumposed on the shaft 25 adjacent the rotor 26 for urging or biasing the rotor in the proper direction. The numeral 30 indicates a circular disk that is secured to or formed integral with the rotor 26, and the disk 30 has a plurality of openings 31 therein, for a purpose to be later described.
As shown in the drawings, a ring 32 is suitably mounted within the housing 18 adjacent the wall 16, and the ring 32 has a port or opening 33 therein, and an outlet 34 is arranged in registry with or communication with the port 33. As shown in the drawings, such as in FIG. 9, ball bearings 7 are interposed between the walls 32 and 30 in order to help minimize friction. The numeral 35 indicates a hose that is connected to the outlet 34, and a manually operable discharge mechanism 36 is connected to the flexible hose 35. The discharge mechanism 36 may include a bushing or handle portion 37 that has a detachable point 38 connected thereto, and the point 38 may be of the type shown in prior patents such as prior US. Pat. Nos. D204,54 7,
D2l6,98l and US. Pat. No. 3,144,867. Numeral 39 indicates a directional wheel for permitting the point 38 to be shifted into different locations, as desired or required. The hand gripping portion 37 has a passageway 40 extending longitudinally therethrough which is in communication with the hose 35. The numeral 41 indicates a transverse bore that is arranged in the hand gripping portion 37, FIG. 7, and a slidable cutofi valve or plunger 42 is movably mounted in the bore 41, there being stop members 43 in the ends of the cutoff member 42 for limiting movement of the member 42 in the bore 41. The numeral 44 indicates a port or aperture that is arranged in the slidable member 42,
As shown in the drawings, the side wall 16 may be held in place by suitable securing elements 45.
The numeral 46 indicates an outlet fitting that is ar- I ranged adjacent the lower portion of the housing 18, FIG. 3, and the interior of the outlet fitting 46 is hollow as at 47, whereby water can selectively flow out through an outlet opening 48 and be discharged through the fitting 46. The numeral 49 indicates a screen that may be suitably retained in the fitting 46 by means of a snap fastener 50 or the like.
Attention is now directed to FIG. 8 of the drawings, wherein there is illustrated an adapter 51 that is adapted to be used when the device of the present invention is to be used with a faucet 55 having external threads 54, instead of the faucet 1 1 that has the internal threads thereon. The adapter 51 includes an enlarged section 52 that is threaded internally as at 54 for engagement with the threads 54. The adapter 52 further includes a portion or section 56 that is threaded internally as at 53 for engagement with the threads 54. The adapter 52 further includes a portion or section 56 that is internally for threaded engagement with the threaded section 22 of the fitting 20.
A washer or gasket 57 may be arranged on the fitting 20 adjacent the threaded section 22, as shown in the drawings.
From the foregoing, it will be seen that there has been provided a device that is adapted to be attached to a conventional faucet whereby water can be discharged into the mouth or onto the teeth or gums of the user, and wherein the water that is discharged will be discharged or dispensed with a pulsating effect, so as to assure meximum benefits from the discharging water. In use, with the parts arranged as shown in the drawings, a device such as the device 10 can be readily attached to a faucet such as the faucet 11 by screwing the section 22 of the fitting 20 into the interior threaded portion of the faucet 11. Then, by turning on the knob or handle 12, the water will flow through the faucet I 1, then through the passageway 21 in the fitting 20, and into the interior or hollow space 19 of the housing 18. As shown in FIG. 3, as the water follows the path indicated by the' arrows, the water will impinge against the blades or impellers 28 of the rotor 26 so as to rotate the rotor 26 on its shaft 25. Some of the water can discharge out through the orifice 48 and then out through the passageway 47 in the outlet 46 so that this water can enter the sink l3 and flow out through the drain 14.
In addition, as the water strikes or impinges on the blades 28, the rotor 26 will be rotated in a counterclockwise direction, FIG. 3, wherein the disk 30 that is part of the rotor 26 will be turned so that the openings 31 in the disk 30 will move into and out of registry with the opening 33 in the stationary ring 32. When the openings 31 and 33 are in registry with each other, some of the water can flow out through these registering openings, as shown in FIG. 2, so that this water will flow out through the hose 35. By manually moving the valve 42 in the bore 41, the port 44 can be either arranged so that it registers with the passageway 40 in the member 37, or else the parts can be arranged as shown in FIG. 7 so that no water can flow out through the tip or point 38 onto the teeth, gums or the like.
It will be noted that when the disk 30 isarranged so that its openings 31 are out of registry with the opening or port 33, that no water will be pumped through the hose 35 and out through the tip 38. Because the rotor and disk 30 are continuously rotating, it will, therefore, be seen that the water that flows out through the tip 38 will be discharged or dispensed with a pulsating effect so that maximum benefits will be achieved from such pulsating water.
When the device is to be used on a faucet such as the faucet 55 that has external threads 54, an adapter 51 shown in FIG. 8 can be used whereby the adapter 51 will serve to effectively connect the external portion 54 of the faucet 55 to the externally threaded portion 22 of the fitting 20.
The parts can be made of any suitable material and in different shapes or sizes.
The attachment of the present invention is adapted to be connected to a standard water faucet either directly, as shown in FIG. 3, or through an adapter as shown in FIG. 8.. When the faucet valve is opened, that is, when the faucet valve 12 is opened, water under approximately 40 to pounds (p.s.i.) flows through the faucet. Since the throat of the attachment is restricted, as indicated by the numeral 21, the pressure will be reduced and the velocity will be accelerated into the body in accordance with Bernoullis law. An opening 48 at the bottom of the body or housing 18 discharges water therethrough to permit a flow of water under pressure through the housing or body 18. The area of the bottom opening 48 is substantially less than the cross sectional area of the throat 21 so that a head of water under pressure is retained within the housing or body 18.
Water that is discharged from the throat or passageway 21 impinges on the blades 18 of the rotor 26 which has the back plate or disk 30 arranged at one edge of the blades. The light spring member 29 urges the rotor 26 against a ring 32 that is constructed of a material that has a low coefficient of friction, such as Teflon, nylon, or the like. In addition, the ball bearings 7 assure that the parts can move in the proper manner with a minimum amount of friction. The ring has an opening 33 in communication with a discharge nipple 34 to which a hose 35 is attached. The back plate or disk 30 has one or more openings 31 which selectively register with the opening 33 in the ring 32 as the rotor 26 is rotated. When the ring opening 33 and one of the plate openings 31 are in registry with each other, water under pressure will be discharged through the hose 35, and when the rotor 26 moves the opening 31 out of registry with the opening 33, the flow of water through the hose 35 is interrupted until another plate opening 31 registers with the ring opening 33.
In addition, the size of the opening 48 in the bottom of the housing controls the rate of rotation of the rotor since the rate of discharge controls the rate of ingress. However, the larger the opening in the bottom, the less pressure the water in the body will be under, so that this construction permits variations, depending upon the construction of the device to give the fastest flow with the desired pressure of the pulses through the hose and out through the tip or point 38.
The present invention relates to a dental and oral prophylactic pulsating water device for home or clinical use, wherein water under a pulsating pressure will be directed into oral areas in the mouth or onto the teeth and gums. The device can be attached to standard plumbing fixtures or faucets, and the device of the present invention is simple and easy to operate and inexpensive to manufacture.
The device of the present invention is constructed so that leakage of fluid or liquid will be prevented, and the parts are made so that friction is minimized.
Attention is now directed to FIGS. through 13 of the drawings, wherein the numeral 60 indicates a modified or alternative faucet and plumbing attachment for an interdental mouth wash dispenser, and the device 60 includes a housing 61 of hollow formation that comprises first and second spaced parallel side walls 62 and 63, FIG. 10. The housing 61 further includes an arcuate end wall 64. The numeral 65 indicates a fitting on the upper end of the housing 61, and the fitting 65 is adapted to be connected to a faucet such as the faucet 11, and the fitting 65 includes a passageway. 66 that provides or defines a throat, and the fitting 65 further includes a reduced diameter threaded portion 67, FIG. 1 1.
As shown in FIG. 10, for example, the bottom portion 69 of the wall 64 is provided with an outlet opening 68 that establishes communication between hollow interior 75 of the housing 61 and the hollow interior 74 of a nipple or fitting 70 that is affixed to the lower portion of the housing. The nipple or fitting 70 includes a cylindricalside wall section 71, as well as a flat end wall section 72, and the wall section 72 has a plurality of outlet apertures or openings 73 therein for a purpose to be later described.
As shown in FIGS. 10, 11 and 13, the numeral 81 indicates a rotor that is rotatably mounted on a shaft or stem 76 that may have one end thereof formed integral with the wall 62, and the shaft 76 extends through a central portion of the wall 63. The shaft or stem portion 76 has a passageway 77 that may be generally L- shaped, and the passageway 77 includes a straight portion 78 as well as a portion 79 that is arranged at right angles to the portion 78. A hose 80 is adapted to be connected to the projecting end of the stem 76, and the hose 80 can serve the same purpose as the previously described hose 35.
The rotor 81 includes a central hub 82 that is rotatably mounted on the stem or shaft 76, FIG. 10. The hub 82 has a port or opening 83 therein that is mounted for movement into and out of alignment or registry with portion 79 of the passageway 77, as the rotor 81 turns or rotates. The rotor 81 further includes a pair of spaced parallel walls or disks 84 and 85, and interposed between the walls 84 and 85 is a plurality of arcuate or curved blades 86, FIG. 11. The numeral 87 indicates a flange portion or stopper that is formed integral with or secured to the wall section 85 of the rotor 81, and the stopper 87 is mounted for movement into and out of opened and closed relation with respect to the outlet openings 68, as the rotor 81 turns within the housing 61.
With further reference to the device shown in FIGS. 10 through 13, it will be seen that in use with the parts arranged as shown in the drawings, the device 60 can be attached to a faucet such as the faucet 11, whereby when the usual knob, such as the knob 12 is turned on, the water will flow into the hollow interior 75 of the housing 61 through the passageway or throat 66. As
this water flows into the interior of the housing through the throat 66, the water will impinge against the blades 86 so as to rotate or turn the rotor 81 on the shaft or stem 76. Spacers 88 and 89 maintain the rotor properly positioned or spaced from the walls 62 and 63, so that the rotor can turn with a minimum amount of friction. As the rotor 81 turns, the port 83 in the hub 82 of the rotor will move into and out of registry or alignment with the portion 79 of the passageway 77, so that water can selectively flow out through the interior of the housing, then through the port 83, then through the portion 79, then through the portion 78 and out through the hose 80. It is to be understood that a suitable discharge tip, such as the discharge mechanism 36 can be suitably connected to the hose 80, whereby a pulsating stream of water can be directed onto the teeth, gums, or other portions of the users mouth in a desired manner.
In addition, as the rotor 81 turns in the housing 61, the flange portion or stopper 87 will move into and out of closed relation with respect to the outlet opening 68 so as to insure that the desired pulsating effect will take place. The water that flows out through the opening 68 when the stopper is moved away from the opening 68 will enter the interior 74 of the nipple 70, and this water will then be discharged out through the aperture 73 into a basin such as the basin 13 previously described.
The device of the present invention can be adapted to new or existing plumbing or fixtures. The water that flows out through the hose will be discharged with a pulsating effect.
The device is a complete unit. In the arrangement shown in FIGS. 10 through 13, the fluid or water enters the housing through the fitting 65, and then the water can selectively flow out through the opening 83 through the passageway 77 when the ports 83 and 79 are aligned. The portion 78 has its longitudinal axis parallel to the longitudinal axis of the member 76. In addition, the stopper 87 will cover the outlet opening 68 when the parts are in the position of FIG. 10 so that all of the force of water will have to discharge out through the hose 80 when the parts are in the position of FIG. 10 to provide a good squirt of water. When the stopper or flange 87 is away from the opening 68, some of the water can flow out through the opening 68 and eventually out through the aperture 73. The total cross sectional area of the stopper 87 is less than the cross sectional area of the float 66, so that even when the stopper or flange 87 is at the top of the housing, the stopper will not completely block the flow of water entering the interior of the housing through the opening 66. Also, the cross sectional area of the outlet opening 68 is smaller than the cross sectional area of the inlet opening 66 in order to assure that the water flows properly through the device. In addition, the total cross sectional area of the aperture 73 is greater than the cross sectional area or size of the outlet opening 68 so that the water will drain through the device without being under substantial pressure.
The present invention provides a pulsating effect by temporarily or selectively stopping up the outlet opening 68 with flange 87 at the instant that the openings 83 and 79 are in registration with each other. Therefore, the device assures that the full pressure of the incoming water will cause the water to discharge through the hose in a pulsating manner.
With further reference to the device shown in FIGS. 10 to 13, when the opening 83 coincides with or registers with the port 79, the discharge opening 68 is closed by the stopper 87. In addition, the combined area of the discharge opening is less than the cross sectional area of the inlet opening. Thus, it will be seen that there has been provided an interdental prophylactic device that includes a housing having a discharge opening, a shaft having a port therein, a rotor that is rotatably mounted on the shaft, and the rotor has a hub with an opening 83 that is mounted for movement into and out of registration with the opening 79. In addition, there is provided a stopper 87 that is carried by the rotor, and the parts are constructed so that when the opening 83 in the revolving rotor coincides with the opening 79 in the shaft 76, the stopper 87 blocks fluid from discharging from the housing discharge opening so that there is obtained the full impact through the in terdental point connected to the hose 80.
With further reference to a device such as that shown in FIGS. 1 through 9, the coacting parts such as the member having the openings 31 therein provide or define two planes with curved or flat surfaces that cooperate to selectively discharge or cut off the supply of water to achieve the desired pulsating effect.
