Abstract
The utility model discloses a one-time spray high-speed turbine dental hand piece which comprises a handle and a nose connected with the handle and is characterized in that a water-gas mixing chamberis arranged in the nose, an intake tube which is connected with the water-gas mixing chamber and is inside the handle is arranged inside the hand piece, a water inlet tube which is connected with thewater-gas mixing chamber and is inside the handle is arranged inside the hand piece, the gas from the intake tube and the water from the water inlet tube enter the water-gas mixing chamber and mix together resulting from the effect of pressure, and then turn into mist and spray out through three spray holes, the spray holes are evenly distributed at the front end of the nose, and the three spray holes which achieve spraying by communicating with the water-gas mixing chamber and are regularly distributed in a ring shape are arranged at the front end of the nose. The utility model provides the one-time spray high-speed turbine dental hand piece with the advantages of high efficiency, convenience and simple structure.
Description
Technical field
This utility model relates to a kind of disposable spraying high speed turbine dental handpiece.
Background technology
At present, the spraying dental handpiece that occurs on market mainly is by handle, head is formed, handle and head inside are provided with air cavity and water cavity, be respectively equipped with three fumaroles and three hole for water sprayings on above-mentioned and the head that air cavity and water cavity are communicated with, these three fumaroles and three hole for water sprayings are forming atomizing and directive dental sewing machine needle when spray orifice sprays simultaneously under the pressure of setting, play refrigerative effect still because air pressure and hydraulic pressure often are difficult to control, during use, it is excessive or too small and cause forming atomizing air pressure or hydraulic pressure to occur through regular meeting, thereby can't be the clinical usefulness that cooling car pin is provided; In addition, because pore and water hole are too little, the phenomenon that also results in blockage easily.
The utility model content
In order to address the above problem, the purpose of this utility model is to provide a kind of service efficiency height, convenience, also has disposable spraying high speed turbine dental handpiece simple in structure.
For achieving the above object, the technical scheme that this utility model adopted is:
Disposable spraying high speed turbine dental handpiece, comprise handle, and the head that is connected with handle, it is characterized in that being provided with water vapor mixing chamber in the described head, described mobile phone inside is provided with water vapor mixing chamber and is connected and the air inlet pipe in handle, described mobile phone inside is provided with water vapor mixing chamber and is connected and the water inlet pipe in handle, the gas of described air inlet pipe and the water of water inlet pipe enter after the water vapor mixing chamber because the relation of pressure mixes, become and vaporificly spray through spray holes, described spray holes has three, be uniformly distributed in the front end of head, the front end on the described head is provided with three and communicates with water vapor mixing chamber and to realize the spray holes of nebulization and annular distribution regularly.
After adopting technique scheme, because the front end on the head is provided with three communicate with the water vapor mixing chamber spray holes of realization nebulization and annular distribution regularly, in use, in any case the size of adjusting spraying all very freely, can be very accurately with spray painting to the car pin, and the aperture of spray holes is bigger, so be not prone to the spray holes phenomenon of blocking, so improved the performance of using, and structure is also very simple.

The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail.
As shown in Figures 1 to 4, comprise handle 1, and the head 2 that is connected with handle 1, be provided with water vapor mixing chamber 6 in the described head 2, mobile phone inside is provided with water vapor mixing chamber 6 and is connected and the air inlet pipe 4 in handle 1, mobile phone inside is provided with water vapor mixing chamber 6 and is connected and the water inlet pipe 5 in handle 1, mobile phone inside is provided with the water vapor mixing chamber 6 that water inlet pipe 5 connects in the head 2, the water of the gas of air inlet pipe 4 and water inlet pipe 5 enters water vapor mixing chamber 6 backs because the relation of pressure mixes, become vaporific through spray holes 3 ejections, described spray holes 3 has three, be uniformly distributed in the front end of head 2, front end on the described head 2 is provided with three and communicates with water vapor mixing chamber 6 and to realize the spray holes 3 of nebulization and annular distribution regularly, and the shape of described spray holes 3 and size can be according to realizing that the needs of producing adjust.
Above-described only is the preferred implementation of the disposable spraying high speed turbine dental handpiece of this utility model; should be understood that; for the person of ordinary skill of the art; under the prerequisite that does not break away from this utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
