Abstract

The utility model relates to a teeth protecting bending structure for a handheld teeth polisher, which mainly comprises a bending main body and a polishing cup, wherein the polishing cup is arranged at the head of the bending main body, a mobile phone connecting end is arranged at the tail end of the bending main body; the teeth protecting bending structure for the handheld teeth polisher is characterized in that an included angle between the axis of the polishing cup and the axis of the mobile phone connecting end is 95-145 degrees. With regards the design of human engineering, as the included angle between the axis of the polishing cup and the axis of the mobile phone connecting end is an obtuse angle so as to compensate an included angle of a wrist and arms of a doctor, so that the doctor can easily realize better attaching of the polishing cup and teeth without over fatigue of the wrist; therefore, muscles and bones of the wrist of the doctor can be protected during teeth polishing; and the polishing cup can be well attached to the surfaces of the teeth by means of the angle, so as to achieve better polishing effect.

Description

Hand-held tooth buffing machine is with protecting tooth bent angle structure

Technical field

This utility model relates to dental care polishing field, is specifically related to a kind of hand-held tooth buffing machine based on ergonomic designs with protecting tooth bent angle structure.

Background technology

The tooth buffing machine is mainly used in prevention to dental disorder, treatment and to cleaning, the polishing (being equipped with special-purpose prevention tooth the upper and lower teeth not meeting properly cream) of dental surface, it mainly---protects tooth bent angle (Prophy Angle) and hand-held power part---by the treatment head, and high speed dentistry headstock (mobile phone) two parts are formed.

U.S. Pat 7255559B2 (Disposable dental prophy angle with secure rete-ntion mechanism) has showed a kind of comparatively common disposable tooth bent angle that protects to us, as described in Figure 1, wherein, the described tooth bent angle 1 that protects mainly is made up of bent angle main body 2 and polishing rotor 3, these polishing rotor 3 contacts also act on dental surface, play the effect of the polishing that cleans one's teeth; Establish polishing rotor 3 on the head of described bent angle main body 2, and its tail end is a mobile phone link 4.As shown in Figure 2, establish driving shaft 5, driven shaft 6 and pair of orthogonal bevel gear 7 in the described bent angle main body 2, driving shaft 5 one ends are for being connected with straight handpiece, and the other end is in transmission connection with driven shaft 6 through described bevel gear with axes at right angles 7, fixedly connected with described polishing rotor 3 concentrics in driven shaft 6 ends; The axial line of driving shaft 5 and driven shaft 6 axial line angles and polishing rotor 3 is identical with the axial line angle of mobile phone link 4, is 90 °.Yet, this kind design protect tooth bent angle 1 in use, but, the axial angle of its polishing rotor 3 and straight handpiece brought some inconvenience owing to being 90 °, as: the doctor is in order to reach good polishing effect, wrist and arm need keep an angle application of force when polishing, 2-3 tooth wrist of general polishing will be ached, and life-time service can cause muscle and the skeleton discomfort around the wrist, even causes damage; In addition, polishing rotor 3 can not well contact with dental surface in the use, and polishing efficiency and effect are often lower.

Therefore, protect the structural shortcoming of tooth bent angle at above-mentioned having now, that how to develop a kind of new structure protects the tooth bent angle to avoid above-mentioned deficiency, just becomes problem to be solved in the utility model.

Summary of the invention

This utility model provides a kind of hand-held tooth buffing machine with protecting tooth bent angle structure, and its purpose is to solve owing to the existing not good awkward problem of bringing of tooth bent angle axis of no-feathering angle of protecting.

For achieving the above object, the technical solution adopted in the utility model is: a kind of hand-held tooth buffing machine mainly is made up of bent angle main body and polishing rotor with protecting tooth bent angle structure, establish polishing rotor on the head of bent angle main body, and its tail end is the mobile phone link; Wherein: the angle of the axial line of the axial line of described polishing rotor and mobile phone link is 95 °～145 °.

Related content in the technique scheme is explained as follows:

1. in the such scheme, described angle is 102 °.

2. in the such scheme, establish driving shaft, driven shaft and a pair of angular bevel gear in the described bent angle main body, driving shaft one end is for being connected with mobile phone, and the other end is in transmission connection through described angular bevel gear and driven shaft, fixedlys connected with described polishing rotor concentric in the driven shaft end; The axial line of driving shaft and driven shaft axial line angle and polishing rotor is identical with the axial line angle of mobile phone link.

This utility model operation principle and advantage are: this utility model is from the ergonomics angle design; be made as the obtuse angle by angle with the axial line of the axial line of described polishing rotor and mobile phone link; thereby the polishing rotor and the axial angle that exists of mobile phone of the angle utilization of doctor's wrist and arm existence being protected tooth bent angle self compensate; make the doctor can be relatively easy to realize that polishing rotor and tooth fit preferably and can not make wrist too tired; therefore can in the tooth polishing process, protect doctor's wrist muscle and skeleton; and can make the good and dental surface applying of polishing rotor by its angle, reach polishing effect preferably.
