Abstract:
1. An electric toothbrush comprising a head which is connected to, or replaceably connectable to, a handle which contains an electric motor, to provide a toothbrush having a head-handle longitudinal direction, wherein the head has: at least one first brush part bearing oral hygiene parts, said first brush part being driveable by the motor in rotary motion about a first rotation axis generally perpendicular to the longitudinal direction; and at least one second brush part bearing oral hygiene parts, said second brush part not being driveable by the motor and being capable of limited reciprocal longitudinal motion; wherein the head contains only one first brush part and only one second brush part, the first and second brush parts being relatively longitudinally disposed along the head-handle direction, the first brush part being furthest from the handle, and the second brush part being adjacent to the first brush part and closer to the handle when connected to the toothbrush handle than the first brush part, wherein the second brush part is enabled to perform limited reciprocal motion by means of end-stop abutment parts on respectively the head and on the second brush part, which abut when the second brush part reaches the ends of its limited reciprocal motion to thereby limit the reciprocal motion.
