The smart electric toothbrush uses the built-in motor drive circuit chip of the toothbrush to make the brush head produce high-frequency swings perpendicular to the direction of the brush handle. The electric toothbrush also has a wireless charging function, which is convenient and quick to use. The smart electric toothbrush solution includes two parts: electric toothbrush control and wireless charging management. The wireless charging solution integrates a wireless charging library, which can communicate with the wireless charging board to improve charging efficiency. The solution is cost-effective, stable, and has a short development cycle. The functions can be customized based on customer needs.
