  • Publication number: 20100154152
    Abstract: The invention relates to an electric toothbrush (10) having a rechargeable energy store (24) that is arranged in an inner space (36) in the body (12) of the toothbrush (10). The inner space (36) is sealed by a primary sealing element (56) against splash water and other detrimental influences.

  • Publication number: 20090183324
    Abstract: The transmission according to the invention for an electric toothbrush serves for the transmission and reforming of a rotational movement provided by an electric motor into a particularly careful and effective cleaning movement of a cleaning element. The ratio of the distance between the longitudinal mid-axis of an output shaft and the longitudinal mid-axis of a drive shaft of the transmission and of the distance between the longitudinal mid-axis of a shaft driving a cam of the transmission and the longitudinal mid-axis of the cam amounts to at least 10:1.

  • Patent number: 7556320
    Abstract: An interdental treatment device, such as a toothbrush, includes a handle configured to accommodate an electric power source, a head carrying an interdental treatment tool, and a neck between the handle and the head. The head or neck includes a mechanical motorized vibratory device, including a drive which causes the head to vibrate. Electrical connections are operably connected to the mechanical vibratory device and the electric power source to power the mechanical vibratory device via the electrical connections. At least parts of the electrical connections are formed by tracks of an electrically conductive plastic material. In various embodiments, a vibration-damping structure dampens vibration transmission from the head to the handle.

  • Publication number: 20090070947
    Abstract: A toothbrush has a removable end cap at its free end area directed away from the bristles, which end cap closes off an inner space of a grip element. The end cap accommodates an electrical control element, in particular a potentiometer, which can be adjusted via an adjustment element arranged rotatably on the end cap. The toothbrush also comprises an electrical power consumption unit, in particular an electric motor, which is designed to set the bristles in vibration. The energy supply from an energy reservoir arranged in the interior to the electrical power consumption unit can be adjusted continuously by means of the control element, as a result of which the vibration intensity of the bristles can be steplessly adjusted.
