Description

A kind of brush head of hand-held tooth buffing machine

Technical field

This utility model relates to dental care polishing field, is specifically related to the brush head structure that a kind of hand-held tooth buffing machine is used.

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.

Wherein, protect the tooth bent angle and be provided with a polishing hairbrush, this polishing hairbrush is made of bristle, base and fixed axis three, and wherein said bristle is fixed on the front end face of base by glue, the end of base convexes with described fixed axis, and is positioned to protect tooth bent angle inside by this fixed axis; The end of described base is formed with angular bevel gear, constitutes a pair ofly with the angular bevel gear with the power output shaft end of tooth buffing machine, reaches the effect of transmitting revolving force.Described polishing hairbrush can be divided into by the difference of its bristle shape: tack brush, tip brush etc., the tooth positions different with correspondence polish.During treatment, facing is polished dipping in corresponding ointment on the bristle, can remove impurity or polishing cuts such as tartar, make dental surface cleaning and smooth.But, not only cause bristle easily to come off and also can bring infringement human body and environment because existing polishing hairbrush uses the glue fasten bristles.

Therefore, at the shortcoming of above-mentioned existing polishing hairbrush, brush head structure how to develop a kind of new structure just becomes problem to be solved in the utility model to avoid above-mentioned deficiency.

Summary of the invention

This utility model provides a kind of brush head of hand-held tooth buffing machine, and the bristle that its purpose is to solve existing brush head easily comes off and to human body and the deleterious problem of environment.

For achieving the above object, the technical solution adopted in the utility model is: a kind of brush head of hand-held tooth buffing machine, mainly form by fixed axis, ring set, several bristle and valve jacket; Described fixed axis one end is crown head; Described valve jacket is the pipe of an open at both ends, is sheathed on described fixed axis outside; The open-mouth of corresponding described crown head one end of this valve jacket is formed with an abutment face, and the rear end of this abutment face and described crown head is against cooperating; Described fixed axis is fixedlyed connected with valve jacket; Described bristle circumferentially evenly is provided with along ring set, and the one end passes the ring set endoporus, and the bristle middle part is via the ring set doubling; Behind described ring set and the bristle location, be sheathed on the rear end of described crown head, and the diameter of ring set is less than the external diameter of described crown head; The outer rim of described ring set then compresses the location by described abutment face.

Related content in the technique scheme is explained as follows:

1. in the such scheme, the open-mouth of corresponding described crown head one end of described valve jacket also is formed with a spigot surface, the described abutment face of outer cause of the corresponding described crown head of this spigot surface extends turnover and forms, with the bristle on the described ring set that leads, make end axially the convexedly stretching in outside the described open-mouth of bristle along fixed axis.

2. in the such scheme, described fixed axis is fixedlyed connected by an inlay card structure with valve jacket, and described inlay card structure is good with latch and bayonet fittings.

3. in the such scheme, described open-mouth inner edge also is provided with a location back-up ring, with the rear end that cooperates described abutment face and described crown head against cooperating.

4. in the such scheme, described ring set can preferably use metal material to make if consider from the intensity aspect, is good with copper.

This utility model operation principle and advantage are: the brush head of a kind of hand-held tooth of this utility model buffing machine, make brush head by the mode of using mechanical clamping, make that the location of bristle is more fastening, simultaneously again because avoided the use of glue, so can not produce adverse influence to human body and environment.
