DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0026] With reference to FIG. 1, an embodiment of a Dental plaque cleanser 100 generally comprises an ultrasonic scaling unit 20, a water jet biofilm cleanser unit 30 and power supply 10.

[0027] With reference to FIG. 2, the ultrasonic scaling unit 20 comprises a water/air supply 24, a controller circuit 25, an oscillator 26, a transducer 27, a handpiece 21, tips 22 and foot controller 23.

[0028] The ultrasonic scaling unit 20 is activated by pushing on the foot controller 23. The said oscillator 26 generates electrical energy including a current, a voltage and frequencies; the said transducer 27 with said handpiece 21 convert the electrical energy and actuate mechanical vibration on a water cooled said tip 22; and the vibrated tip 22 taps the calculus on a tooth.

[0029] With reference to FIG. 3, the water jet biofilm cleanser unit 30 comprises a water supply 33, a controller circuit 34, a motor 35, a coherent pump 36, handle 31 and tips 32.

[0030] With reference to FIG. 4, an embodiment of the coherent pump 36 comprises an inlet/outlet section 51-1. The section 51-1 comprises a pump inlet 53, a pump outlet 52 and a buffer room is inside of the section 51-1. The coherent pump 36 further comprises a chambers section 51-2 and motor driven section 51-3.

[0031] With reference to FIG. 5, a coherent pump 36 comprises three diaphragm chambers 55-1, 55-2 and 55-3 in said section 51-2. Said coherent pump 36 further comprises a lever with triple arms 54-1, 54-2 and 54-3 correspondingly mounted at the bottoms of said three chambers 55-1, 55-2 and 55-3. Each diaphragm chamber has an inlet and an outlet. The FIG. 5 shows the chambers 55-1 has an inlet 56-1 and an outlet 57-1. The FIG. 5 also shows the chambers 55-2 has an inlet 56-2 and an outlet 57-2. The lever's center pole 58 eccentrically inserts into a motor's rotating arm.

[0032] With reference to FIG. 6, a cross-sectional view shows the water flows inside the coherent pump. When the lever arm 54-1 goes down and the chamber 55-1 goes back to its original shape and draws water from inlet 53 though the inlet 56-1 into chamber 55-1. Meanwhile, the lever arm 54-2 goes up and the chamber 55-2 shrink with pressure increases and the water in the chamber 55-2 is propelled out through the outlet 57-2 to the buffer room 59. Said coherent pump draws water in from the inlet 53 by the three diaphragm chambers 55-1, 55-1 and 55-3 take turns unremittingly and the water is propelled out at the outlet 52 is a pressured constant-flow.

[0033] Plurality of exchangeable tips could utilize constant water jet to blasting, penetrating and cleansing biofilms. An embodiment of Swirl jet tip 32 with references to FIG. 7 and FIG. 8, the Swirl jet tip 32 comprises a twist head 70. The twist head 70 comprises a pipe 71 with a close off end, two holes 75-1 and 75-2 opposites each other on the wall of pipe 71, the hole 75-1 is show in the FIG. 8 but another hole 75-2 at the hidden side of pipe 71 and could not show; the twist head 70 further comprises two opposite parallel slopes 76-1 and 76-2 at the close off end of said pipe 71; The twist head 70 further comprises a ring gasket 74, an external thread 73 and a flange 72; The twist head 70 further comprises a cap 77 with internal thread that matches external thread 73 in the pipe 71, and a pinhole 78 centrally located at the top of the cap 77.

[0034] When water flows into said twist head 70 and then flows out from said two holes 75-1 and 75-2 become two flows. The cap 77 is screwed onto the pipe 71, the two water flows are blocked by the cap 77 and ring gasket 74 then two separated flows will go to the two slops 76-1 and 76-2 to twist. And

[0035] With reference to FIG. 9, when the cap 77 is screwed tightly against the pipe 71, twisted two flows eject out from the pinhole 78 form a swirl hollow cone shaped J1 that opens a user's periodontal pocket to wash out plaque therein. The rotating water of swirl hollow cone shaped J1 generates a low pressure zone and suck out plaque in deep of user's periodontal pocket.

[0036] With reference to FIG. 10, when the cap 77 is screwed slight loosely against the pipe 71, twisted two flows eject out from the pinhole 78 form a swirl stream shaped J2 that cleanses a user's tooth extraction site;

[0037] With reference to FIG. 11, when the cap 77 is screwed more loosely against the pipe 71, twisted two flows eject out from the said pinhole 78 form a swirl drilling shaped J3 that cleanses a spot such as a white spot.

[0038] The water jet biofilm cleansing unit 30 cleans dental supragingival and subgingival plaque biofilm.

[0039] Thus, specific embodiments and applications of a dental plaque cleaner have been disclosed. It should be apparent, however, to those skilled in the art that many more modifications beside those already described are possible without departing from the inventive concepts herein.
