Ultrasonic dental scaler transducer

The ultrasonic dental scaler transducer comprises a main rod body, a vibration rod body is arranged at one end of the main rod body, a piezoelectric part enabling the vibration rod body to vibrate is arranged at the joint of the vibration rod body and the main rod body, a first through hole is formed in the main rod body, and a second through hole is formed in the main rod body. And a water outlet hole communicated with the first through hole is formed in the vibration rod body. When water flows out from the end part of the vibration rod body, certain pressure is formed to wash away tartar which just falls off, so that a user can conveniently and clearly see the removal condition of the tartar, a washing function and a tooth cleaning function are ingeniously combined, the purpose of removing the tartar and cleaning at the same time is achieved, and a better tooth cleaning effect is achieved. 本发明公开了一种超声波洁牙器换能器，包括：主杆体，所述主杆体的一端设有振动杆体，所述振动杆体与所述主杆体的连接处设有使所述振动杆体发生振动的压电部，所述主杆体内设有第一通孔，所述振动杆体内设有与所述第一通孔连通的出水孔。水流从振动杆体的端
