This is a dental washing machine.It contains a stand.The front end of the frame is connected with a movement.The base is connected with a casing set outside the core.The front end group of the movement core is provided with a tooth scale scraper；Among them；An air intake channel is arranged in the frame.A valve and a jet hole are arranged to connect the air inlet channel.A control valve is arranged inside the air inlet channel；An eccentric rotor is arranged at the rear end of the movement core.The eccentric rotor corresponds to the blowhole provided on the base.Use high-pressure air to rush out of the jet hole of the engine base.It can drive the eccentric rotor to rotate at high speed.Make the eccentric rotor vibrate rapidly due to the eccentric centrifugal force.The flow of high pressure air through the air jet hole can be adjusted by using the control valve.To control the rotation speed of the eccentric rotor,The vibration frequency of eccentric rotor is adjusted.In this way,Provide a more stable vibration energy and frequency.Make patients more comfortable to receive treatment.And improve the service life of the tooth washing machine.本創作係為一種洗牙機，包含有一機座，機座前端組接有一機芯，該機座並組接有一機殼套設於機芯外，該機芯前端組設有一齒垢刮件；其中；該機座內部設有一進氣通道，並設有一閥門及噴氣孔連通進氣通道，該進氣通道內部設有一控制閥；該機芯後端設有一偏心轉子，該偏心轉子恰對應於機座上所設之噴氣孔，利用高壓空氣急速自機座之噴氣孔噴出，可驅動偏心轉子高速旋轉，使偏心轉子因偏心的離心力而產生快速振動，且利用控制閥可調節高壓空氣通過噴氣孔之流量，以控制偏心轉子旋轉速度，而調整偏心轉子振動頻率；藉此，提供一振動能量及頻率更為穩定，使病患更能舒適接受治療，並提高使用壽命之洗牙機。
