Brush section for an electric toothbrush
First Claim
1. A brush section for an electric toothbrush having a handle section, the brush section comprising:
- a first end adapted to be connected to the handle section;
a second end remote from the first end, the second end including a disk-shaped bristle carrier, the bristle carrier having an end surface which includes bristles arranged in the form of tufts, the tufts being disposed at least on one central ring and on one outer ring, the bristle carrier being mounted on the second end of the brush section so as to be rotatable about an axis of rotation in an alternating oscillating fashion from a central position, the axis of rotation being aligned at an angle to a longitudinal center line of the brush section, wherein the outer ring includes tufts having bristles of different lengths, and adjacent tufts on the outer ring form clusters of tufts, wherein each cluster of tufts has bristles of a length different from bristles of tufts of at least one other cluster.

Abstract
The invention is directed to a brush section (24) for an electric toothbrush (20) in which a handle section (22) is connectible with the brush section (24). A bristle carrier (44) of a circular disk shaped configuration is arranged at the end of the brush section (24) remote from the handle section (22) and has on its upper side bristle tufts (46, 60, 62, 72, 74) disposed on one central ring (54) and one outer ring (56). The bristle carrier (44) is mounted on the brush section (24) so as to be rotatable about an axis of rotation (50) in an alternating oscillating fashion from a central position (58). The axis of rotation (50) is aligned at approximately right angles to a longitudinal center line (52) of the brush section (24). In use of the electric toothbrush (20), an improved cleaning action is accomplished in that the outer ring (56) of the bristle carrier (44) is set with tufts (60, 62) of bristles of different lengths.

39. A brush section for an electric toothbrush having a handle section, the brush section comprising:
-
a first end adapted to be connected to the handle section; a second end remote from the first end, the second end including a disk-shaped bristle carrier, the bristle carrier having an end surface which includes bristles arranged in the form of tufts, the tufts being disposed at least on one central ring and on one outer ring, the bristle carrier being mounted on the second end of the brush section so as to be rotatable about an axis of rotation in an alternating oscillating fashion from a central position, the axis of rotation being aligned at an approximately right angle to a longitudinal center line of the brush section, wherein the tufts on the outer ring include two diametrically arranged clusters of tufts having longer bristles, the two diametrically arranged clusters being positioned substantially along the longitudinal center line of the brush section, and the other bristle tufts on the outer ring and on the central ring have bristles shorter than the longer bristles of the bristle tufts of the diametrically arranged clusters.
