Abstract

The invention relates to a toothbrush head of an electric toothbrush, the toothbrush has a hand-held part with a driving device, a toothbrush head holder connectable to the hand-held part, and a plurality of bristle holders each having a bristle area, these bristle holders are movably arranged on the toothbrush The head bracket can be driven to vibrate by the driving device, wherein the bristle brackets can be respectively connected to the transmission parts of the driving device by means of a driving connection. According to the invention, each bristle holder has a drive coupling, by means of which it can be coupled to an eccentric toggle of a drive transmission, wherein the transmission can be driven in rotation about a longitudinal axis. An improved brushing action can be achieved in a simple manner by means of two separately mounted bristle carrier structures driven by a common drive transmission about different axes of movement. The relative movement of the bristle fields attached to the bristle holder promotes the brushing movement, so that the cleaning action is not achieved solely by the brusher's movements.
