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. |
