Abstract

The invention relates to a power regulation circuit and an ultrasonic tooth cleaner power regulation method. The power regulation circuit comprises an ultrasonic signal generating unit, a driving voltage regulating unit, a voltage modulating unit and an ultrasonic transformer unit; a control signal accesses through the input end of the ultrasonic signal generating unit, the output end of the ultrasonic signal generating unit is connected with the input end of the voltage modulating unit, the output end of the driving voltage regulating unit is connected with the input end of the ultrasonic transformer unit, the voltage modulating unit is connected with the ultrasonic transformer unit, and the output end of the ultrasonic transformer unit is connected to an external driving device. According to the power regulation circuit and the ultrasonic tooth cleaner power regulation method, the calorific value of a tooth cleaner is greatly reduced in the work process, a user can adjust the power of the tooth cleaner according to different parts, the best cleaning effect is achieved, the output of the ultrasonic tooth cleaner is softer, and therefore patients are more comfortable in the therapeutic process.

Description

technical field [0001] The invention relates to the field of electronic control, in particular to a power regulating circuit and a power regulating method for an ultrasonic dental scaler. Background technique [0002] The principle of the ultrasonic scaler is to use the working tip of ultrasonic vibration to contact the surface of the tooth, and achieve the purpose of removing tartar and plaque on the surface of the tooth through physical methods. Ultrasonic scalers need to use ultrasonic transducers to convert electrical energy into mechanical energy of ultrasonic vibration. Combined with the needs of users, the output power of the scaler needs to be adjustable to meet the needs of different users and the clarity of different parts to obtain better cleaning effects . In the traditional way, the output power is adjusted by changing the duty cycle of the ultrasonic signal, but in this way, the voltage modulation unit generates a lot of heat, which will greatly reduce the lif...
