Electric toothbrush system capable of accurately sensing tooth brushing area based on Edge AI

The invention discloses an Edge AI-based tooth brushing area precise sensing electric toothbrush system which comprises an electric toothbrush system applied to an intelligent electric toothbrush and an intelligent bracelet at the same time, and the electric toothbrush system is composed of a battery management module, a motor driving module, a brush head motion control module and a toothbrush ten-axis sensor module. A battery management module, a motor driving module, a brush head motion control module and a toothbrush ten-axis sensor module in the electric toothbrush system are respectively connected with a toothbrush battery, a motor, a toothbrush head and a toothbrush ten-axis sensor of the intelligent electric toothbrush in a control manner through an MCU (Microprogrammed Control Unit) provided with an edge calculation model. When oral cavities of different parts are cleaned, the angle, the vibration frequency and the like of the brush head can be automatically adjusted, the cleaning degree of each part
