Abstract
Disclosed is a dental handpiece structure including a head having a turbine chamber, a rotor installed in the turbine chamber and having a transmission shaft, and a transmission element composed of a plurality of turbine vanes. A high-pressure air entering into the turbine chamber can push each turbine vane to drive and rotate the rotor, and a breach is upwardly formed between two adjacent turbine vanes. A head cap is covered onto the turbine chamber, and a circular groove is formed at the head cap and between an end surface facing the turbine chamber and the transmission element, and the circular groove and each breach are arranged opposite to each other for collecting the high-pressure air guided out from each breach to enhance the cutting force of the dental hand-piece.
Claims7
A dental handpiece structure, comprising:
- a head, having a turbine chamber formed therein, an opening formed at the top of the turbine chamber, a through hole formed at the bottom of the turbine chamber, and an air intake hole and an air vent hole formed on an inner wall of the turbine chamber;
- a rotor, installed in the turbine chamber, and having a transmission shaft, and a transmission element installed at the external periphery of the transmission shaft, and the transmission element being formed by sequentially arranging a plurality of turbine vanes in a circle, and a high-pressure air entering into the turbine chamber through the air intake hole being capable of pushing each turbine vane of the transmission element to drive and rotate the rotor, and a breach being formed between two adjacent turbine vanes of the transmission element and aligned towards the opening, such that the high-pressure air pushing the transmission element is guided out from each breach;
- and
- a head cap, covered onto the opening of the turbine chamber, and having a circular groove formed in a circumferential direction of the head cap and between an end surface of the turbine chamber and the transmission element and disposed opposite to each the breach, for collecting the high-pressure air guided through each breach.
