Title
(EN) Ultrasonic tooth-cleaning equidistant isobaric resorption integrated handle
(ZH) 超声洁牙等距等压回吸一体化手柄
Abstract
(EN)
The utility model provides an ultrasonic tooth cleaning equidistant isobaric resorption integrated handle. An ultrasonic transducer is arranged in the handle shell; the ultrasonic transducer is connected with an ultrasonic working tip; the ultrasonic working tip extends out of the front end of the handle; a positive-pressure water supply hole is formed in the tail end of the handle; an annular back suction hole is formed between the handle shell and the ultrasonic working tip, a negative pressure hole is further formed in the tail end of the handle shell, a back suction cavity is formed in thehandle shell, a silica gel gathering suction sleeve is installed outside the annular back suction hole, a gathering suction cavity surrounding the ultrasonic working tip is formed in the silica gel gathering suction sleeve, and the gathering suction cavity, the annular back suction hole, the back suction cavity and the negative pressure hole are sequentially communicated. According to the ultrasonic cleaning handle, the integrated equidistant isobaric resorption function is ingeniously integrated in the ultrasonic cleaning handle, aerosol is effectively gathered and resorbed to an absorptionset at the beginning of the generation of the aerosol, and the pollution of the aerosol is avoided.
