  • SELF-ADAPTIVE ELECTRIC TOOTHBRUSH
    Publication number: 20230027189
    Abstract: A self-adaptive electric toothbrush includes a handle and a brush head. A vibrating motor is arranged in the handle. Bristles are arranged on the brush head. An output shaft of the vibrating motor extends out of the handle and is connected to the brush head through a delay structure. By the delay structure, the brush head remains stationary or the amplitude of the oscillation of the brush head is less than the amplitude of the oscillation of the output shaft after the vibrating motor is activated and before pressure is applied to the bristles. After pressure is applied to the bristles, the amplitude of the oscillation of the brush head is greater than the amplitude of the oscillation before pressure is applied. In the self-adaptive electric toothbrush, before the pressure is applied, the brush head is stationary or the amplitude of oscillation is small.
