    • An electric motor-driven toothbrush comprising a holder having a motor device and a toothbrush member which has a lever releasably adapted to the holder in a cantilever configuration. The toothbrush member has a number of brushing hairs or `fillings` each of which is thin and resilient, implanted at a brush head portion and a transducer device which converts a rotational movement of a rotor of the motor to a reciprocal linear movement in the direction crossing at right angles to a rotational axis of the rotor. The transducer device is provided at and adjacent to the head portion. The head portion of the brush member is finely and linealy reciprocated at a high speed along the longitudinal direction of each filling.
    • 一种电动马达牙刷,其包括具有马达装置和牙刷构件的保持器,所述牙刷构件具有以悬臂构造可释放地适配于所述保持器的杆。 牙刷构件具有多个刷毛或“填充物”,每个刷子头都是薄而弹性的,植入刷头部分和换能器装置,其将马达的转子的旋转运动转换成沿该方向的往复线性运动 与转子的旋转轴成直角交叉。 换能器装置设置在头部附近并与头部相邻。 刷构件的头部沿着每个填充物的纵向以高速精细地并行地往复运动。
