    • A brush head for an electric toothbrush is disclosed. The brush head includes a substantially plate-shaped bristle support carrying a bristle field, the bristle field having a main axis extending substantially perpendicularly to the bristle support and including a plurality of bristles defining with their free ends a flat or concave working surface to be put onto the teeth to be cleaned; driving and/or transmitting means for driving the bristle support using a reciprocating poking motion along a poking axis and an oscillatory rotational motion about an axis of rotation; and connecting means for connecting the bristle support with a toothbrush handpiece such that a brush head longitudinal axis extends substantially parallel to a toothbrush handpiece longitudinal axis in connected condition. The bristle field with its bristle field main axis is arranged at a tilt relative to the brush head longitudinal axis such that the bristle field main axis is inclined at an acute angle of inclination (Φ) to a perpendicular upon the brush head longitudinal axis, and wherein a working surface is inclined in opposite direction to the tilt of the bristle field main axis such that a plane lying onto the working surface is sloped at an acute angle to a plane perpendicular to the bristle field main axis.
    • 公开了一种用于电动牙刷的刷头。 刷头包括承载刷毛场的基本上板状的刷毛支架,刷毛区域具有基本上垂直于刷毛支撑件延伸的主轴线,并且包括多个刷毛,其定义为其自由端具有待放置的平坦或凹入的工作表面 到要清洁的牙齿上; 驱动和/或传递装置,用于使用沿着戳轴的往复式戳动运动和围绕旋转轴线的振荡旋转运动来驱动刷毛支撑件; 以及用于将刷毛支撑件与牙刷手柄连接的连接装置,使得刷头纵向轴线在连接状态下基本上平行于牙刷手柄纵向轴线延伸。 具有刷毛场主轴的刷毛场相对于刷头纵轴线倾斜布置,使得刷毛主轴以与刷头纵轴线成垂直的倾斜角倾斜(Φ)倾斜,并且 其特征在于,所述工作面与所述刷毛主轴的倾斜方向相反地倾斜,使得位于所述工作面上的平面与垂直于所述刷毛主轴的平面呈锐角倾斜。
