The invention relates to the technical field of dental and oral medical equipment, and discloses a novel wind wheel dental high-speed mobile phone, which includes a mobile phone handle. One end of the mobile phone handle is fixedly connected with a hollow mobile phone head. The air inlet and exhaust port of the mobile phone head are equipped with a vertically arranged bur, the bottom of the bur extends to the outside of the mobile phone head, the top of the bur is provided with a fixing mechanism, and the bur is located on the mobile phone head. The upper end of the inner side wall is fixedly sleeved with a wind wheel, and the outer circular side wall of the wind wheel is provided with a plurality of annular evenly distributed grooves, the grooves correspond to the air inlet, and the top center of the wind wheel is fixedly connected with a protrusion , the raised top is fixedly connected with a top plate, and an exhaust groove is formed between the wind wheel and the top plate. The dental high-speed handpiece of the new wind wheel improves the time and area for compressed air to act on the blade surface, and at the same time accelerates the discharge of gas after doing work, so that the utilization efficiency of wind energy is improved.
Description
technical field [0001] The invention relates to the technical field of dental and oral medical equipment, in particular to a dental high-speed handpiece with a novel wind wheel. Background technique [0002] The main working principle of the dental high-speed handpiece is that the compressed air directly acts on the blade surface of the wind wheel, driving the wind wheel to rotate, driving the center shaft holding the bur to rotate at high speed, and the bur grinds teeth during high-speed rotation. Dental high-speed handpieces on the market use compressed air directly on the middle of the blade surface of the wind rotor, and the working time is short. When exhausting, you must wait for the blade surface of the wind rotor to turn to the position of the exhaust hole. The gas after doing this work cannot be discharged in time. , which in turn hinders the rotation of the wind rotor and cannot efficiently utilize wind energy.
