Description
Technical field
This utility model relates to dental care polishing field, and what be specifically related to a kind of handheld tooth polishing machine protects tooth corner structure.
Background technology
Teeth polisher is mainly used in prevention to dental disorder, treatment and it mainly---protects tooth bent angle (Prophy Angle) and hand-hold type power portion---by treatment head high speed dentistry headstock (mobile phone) two parts form to clean, the polishing (being equipped with special Yu Fang Ya Caries cream) of dental surface.
US Patent No. 7255559B2(Disposable dental prophy angle with secure retention mechanism) show a kind of comparatively common disposable tooth bent angle that protects to us, polishing head wherein contacts and acts on dental surface, plays the effect of the polishing that cleans one's teeth.This polishing head is made up of polishing rotor (rubber cup) and fixed axis two parts, and wherein said polishing rotor (rubber cup) injection moulding is fixed on the front end face of fixed axis, and fixed axis base is positioned to protect tooth bent angle inside; The end of described fixed axis base is formed with angular bevel gear, to form a pair ofly with the angular bevel gear of the power output shaft end of teeth polisher mobile phone, reaches the effect of transmitting revolving force.For alleviate between angular bevel gear and fixed axis and shell and fixture between abrasion, conventionally can be on fixed axis and angular bevel gear application of lubricating.
This kind of handheld tooth polishing machine is easy to use, polishing effect is better, but in the time of life-time service, find to have the following disadvantages: one, in the process of polishing treatment, fixed axis rotary components often changes liquid state because frictional heating can make lubricant into by solid-liquid mixing, its mobility strengthens greatly, part lubricant may be discharged from even and splash out from protecting in tooth bent angle main cavity, and then may pollute the tooth being treated, there is the risk infecting, and may cause the adhesive force variation of amalgam or " filling " material; Two, provide power because most of teeth polishers adopt air driven turbine machine, in use procedure, air can be discharged near the gap being positioned at buffing machine treatment head, has accelerated being discharged from of lubricant; And in the time that mobile phone cuts out work, the moment stopping at mobile phone, the negative pressure that revolving wormgear produces can be aspirated extraneous air and enter the inside of teeth polisher, and the fragment that causes airborne dust or polishing to be produced enters, and pollutes the inside of teeth polisher.
Therefore, how to solve many deficiencies that above-mentioned prior art exists, just become the problem that this utility model will be studied.
Summary of the invention
This utility model provides the teeth polisher of the better sealing of a kind of tool to protect tooth corner structure, and its object is that on the one hand isolating exterior air pollutants enter buffing machine inside, provide on the other hand protect functional oil and stop lubricant overflow pollution working environment.
For achieving the above object, the technical solution adopted in the utility model is: the teeth polisher of the better sealing of a kind of tool protects tooth corner structure, the described tooth corner structure that protects has a housing, this enclosure interior is a chamber, in chamber, be equipped with a rotation fixed axis, the front end of this rotation fixed axis is fixedly connected with a polishing rotor, and the rear end of rotation fixed axis is rotationally connected with described housing, and the middle part of rotation fixed axis is connected and further located with described housing by an inverted U-shaped inserted sheet insert group;
The front end of described rotation fixed axis and the junction of described polishing rotor are provided with an elastic seal ring, and this elastic seal ring is to seal the gap between described housing and described polishing rotor;
The rear end of described rotation fixed axis and the junction of described housing are provided with guarantor's oil space, and this guarantor's oil space is formed at the inwall of described housing, arranges in the form of a ring; And, between the chamber of the oily space of described guarantor and described housing, be communicated with by a finedraw.
Related content in technique scheme is explained as follows:
1. in such scheme, described " elastic seal ring is to seal the gap between described housing and described polishing rotor ", design whereby, can seal on the one hand the lubricating oil of chamber interior, can avoid on the other hand the negative pressure-pumping extraneous air that moment revolving wormgear that mobile phone stops produces to enter the inside of teeth polisher, and then the fragment of having avoided airborne dust or polishing to produce enter and pollute the inside of teeth polisher.
2. in such scheme, described " between the chamber of the oily space of described guarantor and described housing, being communicated with by a finedraw ", design whereby, in the time that lubricant is run out of from the chamber of enclosure interior, because the effect of centrifugal force can be introduced into the oily space of described guarantor, even if lubricated dose of this guarantor oil space is filled up, significantly cut down uncontrollable situation such as therefore also can not splash due to the outer power of lubricant now; On the other hand, the design of protecting oily space also makes to protect tooth bent angle inside can possess lubricant always, extends and protects tooth bent angle service life.
Operation principle of the present utility model and advantage are as follows:
1, this utility model is provided with an elastic seal ring by the junction of the front end at described rotation fixed axis and polishing rotor, this elastic seal ring is to seal the gap between described housing and polishing rotor, can seal on the one hand the lubricating oil of chamber interior, isolate on the other hand external contaminant, prevent that interior of mobile phone is contaminated;
2, this utility model is provided with a guarantor oil space by the junction of the rear end at described rotation fixed axis and housing, therefore can in fixed axis rotary components, maintain lubricant and can not allow the lubricant contamination working environment splashing, and prevents cross-contamination; More can possess certain lubricant owing to can making to protect tooth bent angle inside, protect tooth bent angle service life therefore extended.
