BRUSH PART FOR AN ELECTRIC TOOTHBRUSH AND ELECTRIC TOOTHBRUSH COMPRISING A BRUSH PART OF THIS TYPE

摘要

The invention relates to a simple construction of a brush part (20) of an electric toothbrush, in which the bristle carrier plate (11) executes an oscillating movement about a longitudinal axis and the bristles (15) execute an oscillating rotational movement about their normal axis. The drive assemblies inside the brush part (20) that are required to achieve this movement essentially consist of a transversal pin (8), which is guided in an oblique slot (10) and which is connected to a slide bar (7). The slide bar (7) has toothing on the front end and engages in gear wheels (16) of the bristle carrier (14).
