Description

Integrated abrator head

Technical field

The present invention relates to the medicine equipment that cleans one's teeth, specially a kind of integrated abrator head.

Background technology

Sandblasting toothwash, is to use special sandblasting tooth powder, sprays to facing by the hand-held shower nozzle for declining spray sand-blasting machine and makes a return journey Except bacterial plaque and pigment.

The hand-held traditional structure for declining spray sand-blasting machine includes hand-held sleeve pipe, is provided with the bottom of the hand-held sleeve pipe Sand bottle, nozzle is installed on the front end of hand-held sleeve pipe and is opened and closed by sand-blasting machine Valve controlling, and the pipeline of the rear end of hand-held sleeve pipe passes through Three-way connection connection air pressure is the pneumatic shuttle of 0.4MPa～0.7MPa, and its operation principle is：In venting process, sandblasting Machine (between nozzle and sand-blasting machine valve) produces pressure differential, makes sand bottle inside produce negative pressure, and external pressure is from sand bottle cap On two apertures pour into bottle, make the inside and outside portion's air pressure of bottle reach equal pressure, the grains of sand then spray under suction function from nozzle And reach sandblasting effect.

It is hand-held decline spray sand-blasting machine exist weak point be：

1st, sand-blasting machine valve is too near apart from nozzle, it is impossible into oral cavity depths, operation inconvenience.

2nd, the pressure (0.4MPa～0.7MPa) for needing is excessive, it is impossible to be directly connected to the tooth chair mobile phone buttock line (pressure of tooth chair ≤ 0.4MPa), separately need to use with source of the gas or decompression.

3rd, sandblasting is uneven, and because sand grains is in irregularly shaped and has small weight error, and sand grains is because pressure differential quilt Extract out, cause sand grains extracted quantity different with pressure change.

4th, there are two apertures on sand bottle cap and sand grains cannot be completely enclosed in bottle, sand grains exposure is easily received in atmosphere Tide.

5th, there is serious leakage sand phenomenon.When sandblasting (stopping ventilation) is stopped, storing many sand grains at nozzle and make Into leakage.

6. because internal structure is complicated, it is not easy to dismounting sterilization.

The content of the invention

For the deficiencies in the prior art, the technical problem to be solved is to propose a kind of simple structure, use Convenient, sterilization is easy, the moisture free integrated abrator head of sand grains.

The integrated abrator head of the technical problem is can solve the problem that, its technical scheme includes sandblasting body, and it takes up sand grains Inner chamber is made up of the coaxially spherical cavity of tangent connection and frustum of a cone chamber, and the front portion of the sandblasting body coaxially offers what is connected with spherical cavity Jack, the coaxially connected grafting tracheae in rear portion of sandblasting body, the tracheal orifice connection frustum of a cone chamber of the grafting tracheae, in the jack Be fitted with the inner be passed through sandblasting intracoelomic cavity and can with tracheal orifice grafting and outer end is placed in the external blast tube of sandblasting, the blast tube (blast tube is outwards taken out) opens tracheal orifice and closes jack, stops (blast tube is to interpolation) closing gas during sandblasting when being provided with sandblasting Pore and open jack plug block up.

For ease of operation, the outer end of the blast tube is to axial side deflection.

Conventionally, the angle excursion of the blast tube outer end is less than 30 °.

To adapt to the supply air pressure (being directly connected to tooth chair mobile phone buttock line by grafting tracheae) of 0.2MPa～0.4MPa, institute State spherical cavity radius select for 5.25mm～5.5mm, spherical cavity and frustum of a cone chamber axial overall length select for 11.75mm～ 12.0mm。

To embody integrated effect, the sandblasting body and grafting tracheae integral manufacturing.

Beneficial effects of the present invention：

1st, present invention integration abrator head integrates sandblasting body, grafting tracheae and blast tube, by sandblasting intracoelomic cavity shape The design of shape and the effective control of size, can be directly applied for the supply gas pressure of tooth chair mobile phone buttock line.

2nd, present configuration is compact, is convenient to be operated with the oral cavity of child adult.

3rd, when in use sand grains is completely enclosed within sandblasting body to the present invention, effectively prevents sand grains from making moist.

4th, the present invention can directly carry out disinfection, sanitation and hygiene.
