    • An electric toothbrush comprises a handle casing housing the drive motor, switch components and electric power source, the drive motor providing, by means of a drive system, longitudinal motion and/or partial rotation of a drive shaft of a brush unit mountable on the latter. For reliable detection of the contact pressure, the handle casing is made up of two pivoting, interconnected casing sections (1, 7). One of the casing sections (7) houses the drive shaft (9) of the brush unit (10) and can pivot from a rest position about the pivot point (8) with respect to the longitudinal axis of the other casing section (1) against the force of a spring. During its rotation, and when a medically required contact pressure of the brush unit (10) is reached, the drive shaft (9) acts directly or indirectly on a signal device (18) which produces an acoustic signal mechanically.
    • 电动牙刷包括容纳驱动马达,开关部件和电源的手柄壳体,驱动马达通过驱动系统提供可安装在其上的刷子单元的驱动轴的纵向运动和/或部分旋转 。 为了可靠地检测接触压力,手柄壳体由两个枢转的互连的壳体部分(1,7)组成。 壳体部分(7)中的一个容纳刷子单元(10)的驱动轴(9)并且可以相对于另一个壳体部分(1)的纵向轴线从关于枢转点(8)的静止位置枢转, 反对春天的力量。 在其旋转期间,并且当到达刷子单元(10)的医学上需要的接触压力时,驱动轴(9)直接或间接地作用于机械地产生声学信号的信号装置(18)上。

    • In an electric toothbrush with a handle casing to hold a drive motor switching means therefor and a source of electric power together with a brush body connectable to the drive spindle which can be longitudinally and partially rotatably moved by the drive motor via a reduction gear with downstream crank drives, for the purposes of the safe use of the toothbrush and detection of the pressure applied, the toothbrush casing (1) is formed in one piece and contains the drive motor (2) and the gearing (3, 4; 5, 6, 7; 10, 12) in fixed positions, the drive spindle (13) can be pivoted and/or moved transversely to its central longitudinal axis and, when the medically necessary pressure on the brush body (23) is reached, the drive spindle (13) indirectly or directly actuates a device fitted in the toothbrush casing (1) to generate or trigger an acoustic and/or optical signal.
    • 在具有手柄壳体的电动牙刷中,用于保持驱动电动机的开关装置和电源,以及可连接到驱动主轴的电刷主体,该主体可以通过具有下游的减速齿轮被驱动电动机纵向和部分地可旋转地移动 曲柄驱动器,为了安全地使用牙刷和检测施加的压力,牙刷外壳(1)形成为一体并且包含驱动马达(2)和齿轮(3,4; 5,6 ,7; 10,12)处于固定位置时,驱动轴(13)能够横向于其中心纵向轴线枢转和/或移动,并且当到达刷体(23)上的医学上必需的压力时,驱动主轴 (13)间接地或直接致动装配在牙刷外壳(1)中的装置,以产生或触发声和/或光信号。
