Title:
SINE WAVE DRIVE CONTROL METHOD FOR ELECTRIC TOOTHBRUSH
Document Type and Number:
WIPO Patent Application WO/2020/151223
Kind Code:
A1
Abstract:
A sine wave drive control method for an electric toothbrush; an electric toothbrush is driven by a rotary motor, and the drive control method comprises the following steps: the electric toothbrush receiving a start-up command; the electric toothbrush outputting a first time drive command and inputting an acceleration signal to an output end, and the rotary motor rotating toward a first direction; the electric toothbrush outputting a second time drive command and inputting a deceleration signal to the output end, and the rotary motor rotating toward a second direction; ...; the electric toothbrush outputting an n-1th time drive command and inputting an acceleration signal to the output end, and the rotary motor rotating toward the first direction; the electric toothbrush outputting an nth time drive command and inputting a deceleration signal to the output end, and the rotary motor rotating toward the second direction; the attributes of the acceleration signal and the deceleration signal are opposite to each other, and the first direction is opposite to the second direction; a drive waveform of the rotary motor is a continuous sine wave or a rectangular pulse equivalent sine wave having an equal height and a different width. The present invention may significantly reduce the vibration of the body of the electric toothbrush and reduce noise.
