Electric toothbrush, comprising two individually moving bristle carrying areas, driven by shared mechanism

摘要

The bristle head (2) of the toothbrush (1) is fitted with two individually moving areas (8, 9). A round segment (9) at the top rotates around an axle (12) positioned in a right angle to the handle while a second trapezoidal segment (8) swivels to the left and to the right around an axle also positioned in a right angle to the handle and attached to the center of the wider edge of the element (8). The power is transmitted from the battery accommodated in the handle to a drive shaft (15) connected to an eccentric positioned transmission rod (60).
