    • The invention is directed to a brush section (1) for an electric toothbrush which includes a mounting tube (2) in which a shaft (7) rotary about a longitudinal axis (3) is received. Further, the brush section (1) includes a bristle carrier (11) from which bristles (15) extend in the direction of a brush axis (14). The bristle carrier (11) is rotary about a transverse axis (19) by means of a bearing pin (21). By means of in particular a tapered disk (24), the brush axis (14) and the transverse axis (19) define between them an angle (28) departing from an apex (29). In operation of the electric toothbrush, the bristle carrier (11) performs a nutating motion about the transverse axis (19). This effects a revolving approaching/receding motion of the free ends of the bristles (15) resulting in an improved cleaning action on a user's teeth.
    • 本发明涉及一种用于电动牙刷的刷部分(1),其包括安装管(2),其中容纳有围绕纵向轴线(3)旋转的轴(7)。 此外,电刷部分(1)包括刷毛载体(11),刷毛(15)从刷毛轴线(14)的方向延伸。 刷毛载体(11)通过轴承销(21)围绕横向轴线(19)旋转。 通过特别是锥形盘(24),刷轴线(14)和横向轴线(19)在它们之间限定从顶点(29)离开的角度(28)。 在电动牙刷的操作中,刷毛载体(11)围绕横向轴线(19)执行章动运动。 这使得刷毛(15)的自由端的旋转接近/后退运动导致改善对使用者牙齿的清洁作用。

    • An electric toothbrush (1) is described which incorporates a handle (2) and a brush attachment (3). The handle (2) houses an electric motor (8). Protruding from the handle (2) is a shaft (20), which is coupled to the electric motor (8). The brush attachment (3) can be mounted on the handle (2). The brush attachment (3) supports a bristle head (26) which can be coupled to the shaft (20), and from which protrude a multiplicity of bristles (4). In the operating mode, the bristle head (26) describes a rotary motion (49) and a stroke motion (50), with the frequency of the stroke movement (50) being higher, and preferably substantially higher, than the frequency of the rotary movement (49.) The stroke movement (50) provides a poking action of the bristles (4), which serves to loosen plaque from dental surfaces. The rotary movement (49) serves to wipe away plaque loosened from the dental surfaces.
    • 描述了一种电动牙刷(1),其包括手柄(2)和刷子附件(3)。 手柄(2)容纳电动机(8)。 从手柄(2)突出的是轴(20),其连接到电动机(8)。 刷子附件(3)可以安装在手柄(2)上。 刷子附件(3)支撑可与轴(20)联接的刷毛头(26),并从中突出多个刷毛(4)。 在操作模式中,刷毛头(26)描述了旋转运动(49)和冲程运动(50),其中行程运动(50)的频率比旋转运动(50)的频率高,优选地大大高于旋转运动 运动(49.)行程运动(50)提供刷毛(4)的戳动作用,其用于从牙齿表面松开斑块。 旋转运动(49)用于擦拭从牙齿表面松动的牙斑。
