    摘要： A powered toothbrush which has been designed for improved ergonomics and for assisting the user in using a powered brush in an improved and gentler manner. The powered toothbrush includes a handle portion having a base member at one end thereof. A neck portion extends from the other end of the handle portion with the head coupled to the neck portion. The head includes at least one bristle carrier connected to a drive shaft rotating the at least one bristle carrier in a first rotatable direction. In order to improve the ergonomics and stability of the powered toothbrush, the handle portion is formed asymmetrical about the longitudinal axis of the powered toothbrush and the base member of the handle portion is substantially flat. In this ergonomically-designed powered toothbrush, the width of the base member is less than the greatest width of the handle portion, the depth of the base member is less than the greatest depth of the handle portion, and the height dimension of the neck portion is greater than the height dimension of the handle portion.

    摘要翻译： 一种动力牙刷，其设计用于改善人体工程学，并且以改进和温和的方式帮助用户使用动力刷。 动力牙刷包括在其一端具有基部构件的手柄部分。 颈部从手柄部分的另一端延伸，头部连接到颈部。 头包括连接到驱动轴的至少一个刷毛载体，该驱动轴沿第一可旋转方向旋转至少一个刷毛载体。 为了提高动力牙刷的人体工程学和稳定性，手柄部分围绕动力牙刷的纵向轴线不对称地形成，并且手柄部分的基部构件基本上是平的。 在这种符合人体工程学设计的动力牙刷中，基部构件的宽度小于把手部分的最大宽度，底部构件的深度小于把手部分的最大深度，颈部的高度尺寸 大于手柄部分的高度尺寸。
