Disposable spraying high-speed turbine dental handpiece

Abstract

The invention discloses a disposable spraying high-speed turbine dental handpiece, which comprises a handle and a handpiece connected with the handle. The turbine dental handpiece is characterized in that: a water-air mixing chamber is formed in the handpiece, an air inlet tube connected with the water-air mixing chamber and positioned in the handle is arranged in the handpiece, a water inlet tube connected with the water-air mixing chamber and positioned in the handle is arranged in the handpiece, the air of the air inlet tube and the water of the water inlet tube are mixed together due to pressure after entering the water-air mixing chamber to form fog, the fog is sprayed out through fog spraying holes, the number of the fog spraying holes is three, the three fog spraying holes are uniformly distributed at the front end of the handpiece, and the front end of the handpiece is provided with the three fog spraying holes which are communicated with the water-air mixing chamber to realize the fog spraying effect and are regularly and annularly distributed. The invention provides the disposable spraying high-speed turbine dental handpiece with high use efficiency, convenience and simple structure.

Description

technical field [0001] The invention relates to a disposable spray high-speed turbine dental handpiece. Background technique [0002] At present, the spray dental handpieces appearing on the market are mainly composed of a handle and a head. The handle and the head are provided with air chambers and water chambers. And three spray holes, these three spray holes and three water spray holes are sprayed from the spray holes at the same time under the set pressure to form atomization and shoot to the dental bur, which plays a role in cooling, but due to the air pressure and The water pressure is often difficult to control. During use, the air pressure or water pressure is often too large or too small to form an atomization, so it cannot provide clinical cooling effect for the bur; It is easy to cause blockage. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a disposable spray high-speed turbine dental...
