Technical field
The present invention relates to a kind of tooth cleaning device, the ultrasonic tooth device of a kind of pair of Langevin-type transducer.
Background technology
The cleaning in oral cavity and beauty therapeutic are related to health and the image of people, increasingly come into one's own, and many new technology are arisen at the historic moment, and among these, the application of ultrasonic tooth technology is relatively broad；Ultrasonic tooth principle is that the vibration of ultrasonic wave utilizing frequency to be more than 20 hertz carries out scaling and scrapes the oral medical instrument controlling dental calculus, bacterial plaque；Compared with cleaning one's teeth with traditional craft, have that efficiency is high, speed is fast, wound is light, hemorrhage less, save time, the advantage such as laborsaving；The main working parts of ultrasonic cavitron is ultrasonic transducer, ultrasonic transducer converts electric energy to mechanical vibrational energy under the high frequency oscillating current effect that frequency is more than 20 hertz, excitation work head cutter produces same frequency vibration, reaches to smash dental calculus, the purpose of loose tartar；The energy conversion efficiency of ultrasonic transducer directly influences the service behaviour of tooth-cleaning machine；The transducer that currently used ultrasonic cavitron uses is made up of single Langevin-type transducer, the mechanical vibrational energy obtained is less, Langevin-type transducer is a kind of oscillator utilizing longitudinal effect to have higher-energy conversion efficiency, produce axial vibration under the high frequency oscillating current effect more than 20 hertz of the piezoelectric ceramics in Langevin-type transducer, and be delivered to end along oscillator；But single Langevin-type transducer only produces axial vibration, track is single, inefficient.
Summary of the invention
For the technical problem of above-mentioned existence, it is an object of the invention to: propose the ultrasonic tooth device of a kind of pair of Langevin-type transducer.
The technical solution of the present invention is achieved in that the ultrasonic tooth device of a kind of pair of Langevin-type transducer, comprises work cutter head, connector and Langevin-type transducer；Described work cutter head is arranged on connector, and Langevin-type transducer is connected with connector；Described Langevin-type transducer comprises vibrating arm, luffing cone, connection dish, the first piezoelectric ceramic piece, the second piezoelectric ceramic piece, the first balancing weight and the second balancing weight being sequentially connected with；Described Langevin-type transducer has two, and the vibrating arm of two Langevin-type transducers is both connected on connector.
Preferably, said two Langevin-type transducer center line be mutually perpendicular to.
Preferably, described connector is provided with shoulder hole, shoulder hole is provided with and holds out against screw, hold out against screw and the tail end of work cutter head is pressed in shoulder hole.
Preferably, the luffing cone of said two Langevin-type transducer, connection dish, the first piezoelectric ceramic piece, the second piezoelectric ceramic piece, the first balancing weight and the second balancing weight all connect fixing by an attachment screw.
Preferably, the connection Pan Chu of said two Langevin-type transducer is provided with fixed support.
Due to the utilization of technique scheme, the present invention compared with prior art has the advantage that
The ultrasonic tooth device of double Langevin-type transducers of the present invention, by exciting two Langevin-type transducers to do symmetrical mode and the antisymmetry mode of reversely stretching vibration of stretching vibration in the same direction simultaneously, make the work cutter head both can be axially vibrated, make the work cutter head both can be axially vibrated, can radially vibrate again, make work cutter head can play the effect preferably cleaning facing.

Detailed description of the invention
The present invention is described below in conjunction with the accompanying drawings.
As shown in Figure 1-2, the ultrasonic tooth device of a kind of pair of Langevin-type transducer of the present invention, comprise work cutter head 1, connector 2 and Langevin-type transducer；The head design of described work cutter head 1 becomes flat, can expand the contact area with tooth；Described work cutter head 1 is arranged on connector 2；It is provided with shoulder hole on described connector 2, shoulder hole is provided with and holds out against screw 10, hold out against screw 10 and the tail end of work cutter head 1 is pressed in shoulder hole；Described Langevin-type transducer has two, each Langevin-type transducer all comprises vibrating arm 3, luffing cone 4, connection dish the 5, first piezoelectric ceramic piece the 6, second piezoelectric ceramic piece the 7, first balancing weight 8 and the second balancing weight 9 being sequentially connected with, and two Langevin-type transducers are all connected on connector 2 by its vibrating arm 3；Said two Langevin-type transducer center line be mutually perpendicular to；The luffing cone 4 of said two Langevin-type transducer, connection dish the 5, first piezoelectric ceramic piece the 6, second piezoelectric ceramic piece the 7, first balancing weight 8 and the second balancing weight 9 all connect fixing by an attachment screw 12；The connection Pan5Chu of said two Langevin-type transducer is provided with fixed support 13.
During work, Langevin-type transducer has symmetric and anti-symmetric both modalities which, when two Langevin-type transducers do the stretching vibration of homophase simultaneously, is the formation of symmetrical mode, now, work cutter head 1 forms vibration axially；When two Langevin-type transducers do the most reverse stretching motion simultaneously, it is the formation of antisymmetry mode, now, work cutter head 1 is formed along vibration radially；The first piezoelectric ceramic piece 6 and the second piezoelectric ceramic piece 7 it is provided with on said two Langevin-type transducer, sinusoidal wave and cosine wave voltage signal is applied wherein on the first piezoelectric ceramic piece 6 in a Langevin-type transducer and the second piezoelectric ceramic piece 7, sinusoidal wave and negative cosine wave voltage signal is applied on the first piezoelectric ceramic piece 6 in another Langevin-type transducer and the second piezoelectric ceramic piece 7, symmetric and anti-symmetric mode can be excited simultaneously, make work cutter head 1 do when axially and radially vibrating simultaneously, define elliptical path, act on tooth face and can preferably clean facing.
Due to the utilization of technique scheme, the present invention compared with prior art has the advantage that
The ultrasonic tooth device of double Langevin-type transducers of the present invention, by exciting two Langevin-type transducers to do symmetrical mode and the antisymmetry mode of reversely stretching vibration of stretching vibration in the same direction simultaneously, make the work cutter head both can be axially vibrated, make the work cutter head both can be axially vibrated, can radially vibrate again, make work cutter head can play the effect preferably cleaning facing.
Above-described embodiment is only for technology design and the feature of the explanation present invention; its object is to allow person skilled in the art will appreciate that present disclosure and to be carried out; can not limit the scope of the invention with this; all equivalence changes made according to spirit of the invention or modification, all should contain within the scope of the present invention.
