Teeth polisher with novel polishing cup and repeatable rotating protects tooth bent angle
Technical field
The present invention relates to dental care polishing field, and in particular to one kind has improved structure polishing rotor and polishing rotor can be again The teeth polisher shield tooth corner structure of multiple rotating.
Background technology
Teeth polisher is mainly used in prevention, treatment and the cleaning to dental surface, polishing to dental disorder(It is equipped with Special antiscuffing paste)Its primary treatment head --- shield tooth bent angle(Prophy Angle)And hand-hold type power portion --- at a high speed Dentistry headstock(Mobile phone)Two parts are constituted.
The polishing rotor for protecting tooth bent angle is contacted and acts on dental surface, plays a part of the polishing that cleans one's teeth.The polishing rotor is by throwing Light cup(Rubber cup)Constituted with both fixing axles, wherein the polishing rotor(Rubber cup)Injection is fixed on the front end face of fixing axle On, fixing axle base is positioned inside shield tooth bent angle;The end of the fixing axle base is formed with angular bevel gear, with tooth The angular bevel gear of the driveshaft end of polishing machine is constituted a pair, reaches the effect of transmission revolving force.
General rotational structure shield tooth bent angle drive shaft delivers axially equidirectional continuous rotation fortune to fixing axle as described above It is dynamic.In general, axial-rotation pattern can have various, most common to have equidirectional continuous rotation and reciprocating rule to rotate.
Conventional reciprocating formula rotational structure generally has the stud or cunning of the eccentric setting being located between drive shaft and driven shaft Block and conduit, by the reciprocating motion in the channel of stud or sliding block, so as to the equidirectional continuous of drive shaft be converted into The reciprocating rotation of driven shaft.Such as Chinese patent 03224896.2, its transmission mechanism includes that the bias in brush bar turns Axle, the sliding block for being sheathed on guide shaft and being driven by eccentrically weighted shaft and one are by slider-actuated and around the rotation of brush head axis reciprocating rotation Rotor.Sliding block offers a groove near one end of eccentric drive shaft, and its other end is provided with driving cog.The top position of eccentrically weighted shaft In in groove, driving cog gnaws conjunction with the gear being fixed on gyrator.When eccentrically weighted shaft rotates under motor-driven, sliding block Moved reciprocatingly simultaneously with gyrator, so that bristle motion fixed thereon is driven, to reach the effect of cleaning tooth.
The technical problem to be solved is as follows:
First, the reciprocating rotation of polishing rotor is realized on shield tooth bent angle, so as to reach more preferable therapeutic effect, and is reduced to turning The burden of dynamic element, reduces the requirement to material, so as to reduce production cost;
2nd, because teeth polisher is generally driven with speed higher, stud or pin in conventional reciprocating formula rotational structure make There is the risk of fracture with period.Additionally, coordinate firmly good stud or sliding block and conduit to be formed, drive shaft and driven The manufacture of axle becomes relatively more complicated difficulty;
3rd, stop the rotation of drive shaft first when needing to allow reciprocating rotation to stop in conventional reciprocating formula rotational structure, drive Axle forces driven shaft to be locked relative in the housing where drive shaft and driven shaft.Generally, this locking is to housing and driven shaft It is applied with larger stress.
In addition, United States Patent (USP) US 7255559B2(Disposable dental prophy angle with secure retention mechanism)To we show a kind of relatively conventional disposable shield tooth bent angle, polishing rotor contact therein And dental surface is acted on, play a part of the polishing that cleans one's teeth.The polishing rotor is by polishing rotor(Rubber cup)With fixing axle two parts structure Into wherein the polishing rotor(Rubber cup)Injection is fixed on the front end face of fixing axle, and fixing axle base is positioned at shield tooth bent angle It is internal;The end of the fixing axle base is formed with angular bevel gear, with the power output shaft end with polishing of teeth hand set Angular bevel gear constitute a pair, reach transmission revolving force effect.

The prior art has the following disadvantages:
First, traditional polishing rotor extend internally rib and symmetrical blading structure make polishing rotor can effective cleaning dental surface, but They can not provide the cleaning to gum and the gum seam on tooth periphery.Gum is of the gingiva tissue for surrounding tooth neck Point, gum crack is a part for the base portion slightly less than gum base surface of gum eruption tooth.And effective cleaning of teeth Need the bacterial plaque removed from the gum seam of dental surface, gum and tooth periphery, spot and microorganism;
2nd, begun to before antiscuffing paste contact tooth of the rotation of polishing rotor generally in cup.When polishing rotor rotates, centrifugation Power perpendicular to rotation axis, and due to the outward-dipping design of wall of cup, so the component of the centrifugal force will be along polishing cup sidewall Inner surface be directed to outside polishing rotor, the antiscuffing paste in cup by centrifugal force pulls from cup to cup external migration.Existing structure Blade, the line of its root and wall of cup with polishing rotor axis at grade, therefore the migration of antiscuffing paste can not be suppressed. Cause antiscuffing paste to be often prematurely released from cup, waste lotion;
3rd, while the excessive antiscuffing paste being released causes the pollution of operating environment, the discomfort of patient is increased, in making patient mouthful The excessive antiscuffing paste of intake;Also operating process efficiency has been had a strong impact on, dentist not repeatedly must not fill antiscuffing paste to enter Row treatment operation.
