Abstract
A kind of dental handpiece turbine, including turbo main body and inner core, the turbo main body include that several turbine leafs of turbine circumferential direction are arranged in, and the turbo main body lower end surface is equipped with choke face, and the windward side of the turbine leaf is by up to the gradually smaller curved surface of descending slope.The setting of the utility model turbine windward side curved surface can reduce air pressure loss, and the setting of the curved surface of unilateral choke face and windward side from top to bottom is so that turbine type mass concentration, reduces the diameter jump during turbo driving；Turbine is stable to greatly reduce noise.
Description
Technical field
The utility model relates to a kind of dental handpiece turbines.
Background technique
Impeller Mass on the market is not concentrated at present, and great diameter can be generated in running at high speed and is jumped, and impeller one at present
As be made using CNC lathe, high production cost.
Summary of the invention
In order to overcome the shortcomings of that the prior art is above-mentioned, the utility model provides a kind of dental handpiece turbine.
The technical scheme in the invention for solving the technical problem is: a kind of dental handpiece turbine, including turbo main body with
And inner core, the turbo main body include that several turbine leafs of turbine circumferential direction are arranged in, the turbo main body lower end surface is equipped with choke
Face, the windward side of the turbine leaf are by up to the gradually smaller curved surface of descending slope.
Preferably, the turbo main body is wholely set with inner core.
The utility model can be once molded during fabrication using mold.The application method of the utility model and other
Impeller is consistent, does not repeat again.
The utility model has the beneficial effects that: curved surface setting in turbine windward side can reduce air pressure loss, unilateral choke
The setting of the curved surface of face and windward side from top to bottom is so that turbine type mass concentration, reduces the diameter jump during turbo driving；
Turbine is stable to greatly reduce noise.
Detailed description of the invention
Fig. 1 is the utility model perspective view.
Fig. 2 is the utility model side view.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As illustrated in fig. 1 and 2: a kind of dental handpiece turbine, including turbo main body 1 and inner core 2, the turbo main body 1 are wrapped
Several turbine leafs 11 that turbine circumferential direction is set are included, the turbo main body lower end surface is equipped with choke face 12, and the turbine leaf is met
Wind face is by up to the gradually smaller curved surface 13 of descending slope.
Turbo main body described in the present embodiment is wholely set with inner core.
The utility model can be once molded during fabrication using mold.The application method of the utility model and other
Impeller is consistent, does not repeat again.
