Oral nursing device, control method, electronic device, and storage medium

An oral nursing device control method applied to an oral nursing device, the oral nursing device comprising:

• a cleaning portion at least provided with a cleaning unit;
• a grip portion connected with the cleaning portion;
• an actuation assembly at least partially accommodated in the grip portion, the actuation assembly comprising an output shaft engaged with the cleaning portion;
• and
• a control assembly;
• the method comprising:
• generating, by the control assembly, a driving signal to drive the output shaft of the actuation assembly to output a periodic cleaning motion and thus drive the cleaning unit;
• wherein the periodic cleaning motion comprises a plurality of cleaning motions, and each of the plural cleaning motions comprises a first motion and a second motion;
• the driving signal is a pulse width modulation signal;
• the control assembly generates a pulse width modulation signal with a first duty cycle to allow the output shaft to correspondingly output the first motion, the control assembly generates a pulse width modulation signal with a second duty cycle to allow the output shaft to correspondingly output the second motion, and the pulse width modulation signal with the first duty cycle and the pulse width modulation signal with the second duty cycle have different current input directions;
• the first duty cycle of at least one cleaning motion is greater than that of an adjacent cleaning motion, and the second duty cycle of the at least one cleaning motion is smaller than that of the adjacent cleaning motion.
