The invention belongs to the technical field of ultrasonic atomization, and provides an ultrasonic atomizer liquid shortage protection circuit and a liquid shortage control method. The circuit comprises a coupling module, a control module, a voltage transformation module and a detection module. The coupling module is connected with a PWM transmitting device and the control module and used for transmitting pulse signals transmitted by the PWM transmitting device to the control module. The control module is connected with the voltage transformation module and used for controlling the input frequency of an input power source of the voltage transformation module. The voltage transformation module is connected with the detection module and used for providing input voltage for the detection module, the detection module is used for linearly converting the input voltage into detection signals and outputting the detection signals to the detection device, and accordingly the detection device judges whether an ultrasonic atomizer is in liquid shortage or not according to the detection signals. According to the ultrasonic atomizer liquid shortage protection circuit and the liquid shortage control method, whether the ultrasonic atomizer is in the liquid shortage state or not can be rapidly and accurately judged according to different voltage values output when the ultrasonic atomizer is ina liquid shortage state and a non-liquid-shortage state.
Description
technical field [0001] The application belongs to the technical field of ultrasonic atomization, and in particular relates to a liquid shortage protection circuit and a liquid shortage control method of an ultrasonic atomizer. Background technique [0002] With the development and application of ultrasonic technology, ultrasonic nebulizer is called an indispensable medical instrument for the treatment of respiratory diseases. Ultrasonic nebulizer has the advantages of simple structure, convenient use, stable treatment effect, no pain, less drug side effects, and low cost. It is widely used clinically in large, medium and small medical institutions. At the same time, it can also be used as a health care instrument for ordinary families, which can humidify and disinfect the air in the family, and play a role in preventing and treating diseases. [0003] The ultrasonic atomizer can atomize the liquid contained in the liquid container through the ultrasonic wave generated by th...
