[0005] The present invention relates generally to an oral hygiene device, and more particularly to a high-pressure water-spray device for cleaning the teeth.

[0006] The toothbrush is generally used to clean the teeth; however it is difficult to reach certain areas of the mouth. In addition, the toothbrush cannot remove effectively and thoroughly bits of food from the space between the teeth. The dentist often uses a high-pressure water-spray device to clean the teeth of a person under treatment. However, such a dental device is designed for use exclusively by the dentist or dental assistant.

[0007] The primary objective of the present invention is to provide a high-pressure water-spray device which is designed for use by an individual to clean his or her own teeth.

[0008] The device of the present invention comprises a faucet connector and a high-pressure water-spray unit which is formed of a fastening member, a rotary member, a water-spray member, and a flow adjusting valve. The device of the present invention can be connected to a faucet for cleaning the teeth of a person. The device can be turned in all directions so as to enable the water jet stream to reach all areas of the mouth.

[0009] The features, functions, and the advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of a preferred embodiment of the present invention with reference to the accompanying drawings.

[0011] FIG. 2 shows a perspective view of the preferred embodiment of the present invention.

[0012] FIG. 3 is a sectional schematic view of the preferred embodiment of the present invention to show the angular adjustment of the water jet stream.

[0013] FIG. 4 is a sectional schematic view to show the flow control mechanism of the preferred embodiment of the present invention.

[0014] FIG. 5 is a sectional schematic view to show the flow stoppage mechanism of the preferred embodiment of the present invention.

[0015] FIG. 6 shows a schematic view of the preferred embodiment of the present invention in use.

[0016] As shown in FIGS. 1-6, a high-pressure water-spray device embodied in the present invention comprises a faucet connector 10, a fastening member 20, a rotary member 30, a water-spray member 40, and a flow control valve 50.

[0017] The faucet connector 10 is of a hollow cylindrical construction and is provided at one end with a connection portion 11 engageable with a faucet (not shown in the drawings). The faucet connector 10 is provided at other end with a water discharge hole 12, and in a longitudinal side wall with a water output hole 13. The discharge of water can be controlled by a control piece 14.

[0018] The rotary member 30 is provided with a rotary water inlet 31, which is fastened with a connection end 22 of the fastening member 20 is conjunction with a washer 33. The fastening member 20 has a fastening end 21 which is fastened with the water output hole 13 of the faucet with the water output hole 13 of the faucet connector 10. The water inlet 31 is provided with an inner threaded portion 32 which is fastened with the connection end 22 of the fastening member 20. The rotary member 30 is provided in an interior with an L-shaped water channel 34 in communication with the rotary water inlet 31. The rotary member 30 is further provided in the interior with a waterspray hole 35 in communication with the water channel 34. The water-spray hole 35 is provided with a locating slot 36 for locating a washer 375 and a stop ring 38. The water-spray member 40 is provided with a barrel 41 having a jet nozzle 42. The rotary member 40 is rotatably disposed in the locating slot 36 in conjunction with the washer 37 and the stop ring 38. The water-spray member 40 is confined by the stop ring 38; nevertheless it is capable of turning in all directions. The locating slot 36 is provided with an inner threaded portion 361, while the stop ring 38 is provided with an outer threaded portion 381. The stop ring 38 is located in the locating slot 36 such that the outer threaded portion 381 is engaged with the inner threaded portion 361 of the locating slot 36. It must be noted here that the water-spray member 40 is of a spherical construction. Accordingly, the locating slot 36 is similar in profile to the water-spray member 40. The stop ring 38 is provided with a slotted end 382 to facilitate the turning of the stop ring 38 by a screwdriver.

[0019] The rotary member 30 is further provided with a receiving slot 39 in communication with the water channel 34. The receiving slot 39 is used to receive rotatably the flow control vale 50 in conjunction with a washer 53 and a confinement ring 54. The flow control valve 50 is provided with a through hole 51, a turning portion 52, and an annular projection 55 located between the through hole 51 and the turning portion 52. The confinement ring 54 is rested on the projection 55 such that an outer threaded portion 541 of the confinement ring 54 is engaged with an inner threaded portion 391 of the receiving slot 39 of the rotary member 30. The flow control valve 50 is turned by the turning portion 52 so as to enable the through hole 51 to be aligned with the water channel 34 of the rotary member 30. The turning portion 52 is provided with a slotted top end 521 to facilitate the turning of the turning portion 52 by a screwdriver.

[0020] The confinement ring 54 is provided with a slotted top end 54 to facilitate the turning of the confinement ring 54 by a screwdriver.

[0021] The embodiment of the present invention described above is to be regarded in all respects as being illustrative and nonrestrictive. Accordingly, the present invention may be embodied in other specific forms without deviating from the spirit thereof. The present invention is therefore to be limited only by the scope of the following claims.
