Embodiment 1

[0023] This embodiment provides a miniaturized hand-held comfortable dental scaler, such as figure 1 , the miniaturized hand-held comfortable dental scaler includes an MCU module with an NCO frequency control unit to directly drive a power amplification module, and the power amplification module is connected to an ultrasonic transducer.

[0024] The invention omits the frequency generating device of the traditional circuit and reduces the volume.

[0025] Preferably, the ultrasonic transducer is connected to the NCO frequency control unit in the MCU module through the power feedback unit to realize resonance point tracking and realize the resonance point operation of the ultrasonic transducer. The hardware scheme of phase tracking is omitted, which saves cost and space, and is beneficial to equipment miniaturization. Since the heating of the ultrasonic transducer will cause the shift of the resonance point, and the shift of the resonance point will cause heat generation and l...

Abstract

The invention relates to a miniature handheld comfortable dental descaler, and solves the problem that a size is large, cost is high, a working tip needs water cooling during working, trained personnel are required for use, and personal use is inconvenient. Through adoption of the technical scheme that the miniature handheld comfortable dental descaler comprises an MCU module with an NCO frequencycontrol unit which directly drives a power amplification module, and the power amplification module is connected with an ultrasonic transducer, the problem is better solved, and the miniature handheld comfortable dental descaler can be applied to dental descaler application.

Description

technical field [0001] The invention relates to the field of dental scalers, in particular to a miniaturized hand-held comfortable dental scaler. Background technique [0002] Ultrasonic dental scaler is a hand-held device that transmits the energy required for dental surgery by mechanical transmission. According to different power sources, it can be divided into pneumatic and electric. It is used to hold rotating instruments such as burs, dental drills, and dental files, and drive their movements to achieve dental operations such as cutting, grinding, chipping, and drilling. [0003] The current ultrasonic dental scaler utilizes ultrasonic vibration and water mist to rinse and remove dental calculus and tartar. The dental scaler in the prior art has a large volume and high cost, and the working tip needs to be cooled by water during operation, and only trained personnel can use it, which is inconvenient for personal use. Hand-held dental scalers are large in size, low in...
