Ultrasonic dental scaler transducer with liquid absorption function

The ultrasonic dental scaler transducer with the liquid suction function comprises a transducer body, a liquid suction hole is formed in the transducer body, and one end of the liquid suction hole is communicated with a suction device providing negative pressure for the other end of the liquid suction hole. The dental scaler can clean teeth through ultrasonic vibration while providing negative pressure for the liquid suction hole in the dental scaler through the suction device, so that dirt, cleaning liquid, saliva and the like in an oral cavity are sucked and removed from the liquid inlet end of the liquid suction hole, and the dirt and the like in the oral cavity can be removed in time; a liquid suction pipe does not need to be additionally placed in the oral cavity, the liquid suction function and the tooth cleaner are combined into a whole, operation of a user is more convenient, and meanwhile the use experience of the user is improved. 本发明公开了一种具有吸液功能的超声波洁牙器换能器，换能器主体，所述换能器主体内设有吸液孔，所述吸液孔的一端与为其另一端提供负压的抽吸装置连
