Electric toothbrush with inclined bristles in brush section

摘要

The cleaning head (10) of the motor-driven toothbrush (1) has a brush section (4) which is, pref. exchangeably, coupled to the drive part (2). The bristles (8) are held in such a direction that they are inclined when in use to the tooth surface to be cleaned. The drive part puts the brush section in pulsating oscillation (16) in a direction (14) approximately at right angles to the surface to be cleaned. The bristle ends are thus pushed over the tooth surface and reciprocatingly returned.
