  • Publication number: 20180228583
    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.

  • Publication number: 20140237744
    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.

  • Patent number: 8382208
    Abstract: The inventive handle for a brush, in particular for a toothbrush or a domestic brush, has an integral handle body with a hollow space which is surrounded by a wall. Recesses which are offset in relation to one another and open into the hollow space are formed in the wall. The handle is produced from a plastic in an injection-molding process using an injection-molding die which has finger elements, with sections of these finger elements touching in a sealing manner when the injection-molding die is in the closed state and, as a result, these finger elements forming the recesses and the hollow space in the hardened handle.
