Abstract: The invention relates to a small electrical appliance, for example an electric toothbrush (1), with two elements to be driven and with an electric motor (10). The small electrical appliance has a device (16.1; 16.2; 16.3) that drives the first and/or the second element depending on the direction of rotation of the electric motor (10). The first element to be driven can be a movable brush head (2), and the second element to be driven can be a pump (7, 14) for conveying a care agent to the brush head (2) from a reservoir, wherein the device (16.1, 16.2, 16.3) drives the brush head (2) in both directions of rotation of the electric motor (10), but drives the pump (7, 14) only in one direction of rotation of the electric motor (10).

Abstract: An electric toothbrush with a removable brush section having a transponder communicating with a handle portion of the toothbrush via a non-contacting inductive coupling.

Abstract: The invention is directed to a brush attachment adapted to be attached to and detached from a shaft of a handle of an electric toothbrush, including a bristle area, a brush shank and a plug-on part disposed in the brush shank, wherein the plug-on part includes a first spring element and a second spring element which act on the shaft when the brush attachment is plugged onto the shaft. This establishes a connection without play between the brush attachment and the shaft, enabling relatively high vibration frequencies to be transmitted.

Abstract: A brush attachment of an electric cleaning device, the cleaning device including a coupling section to which the brush attachment can be joined. The brush section can include an open end configured to releasably attach to the coupling section of the cleaning device and an interlock canceling element configured to engage the coupling section and displace a longitudinally displaceable drive mechanism extending from the cleaning device a predetermined distance to control the operation of the cleaning device.

Abstract: An electric motor for a small-scale electrical appliance, such as a toothbrush or shaver. The electric motor includes at least one oscillatory motor component, a magnet arrangement having at least one permanent magnet, and a coil for generating a magnetic field which, in interaction with the magnet arrangement, generates a force for excitation of an oscillatory linear motion. During the interaction between the magnet arrangement and the magnetic field produced by the coil, a torque for excitation of an oscillatory rotational motion is additionally generated.

Abstract: An electric toothbrush has a brush head which is mounted in a movable manner, and a drive for producing an oscillating operating movement in the brush head. The drive includes a cyclically movable drive part and a follower part. The follower part is biased against the drive part so that the follower part follows the drive part's cyclic drive movement. A sensor determines the brush head's contact pressure by sensing the extent of coupling between the follower part and the drive part, and determining the contact pressure of the brush head based on the extent of coupling.

Abstract: The invention is directed to a dental cleaning device. It relates in particular to a handle section of an electric toothbrushing device, with a coupling section for coupling various cleaning tools thereto, a drive mechanism for driving the coupled cleaning tool, and a control device for controlling the drive mechanism. The invention further relates to such cleaning tools. According to the invention the handle section includes an electronic interlock device which is deactivated by an encoded interlock canceling element on the cleaning tool only when the cleaning tool is coupled to the handle section (FIG. 4).
