Abstract
A toothbrush head of an electric toothbrush, the toothbrush extending longitudinally and having a hand part, the toothbrush head including a drive rocker, a brush-head carrier coupled to the drive rocker, a main bristle carrier and an additional bristle carrier, both carriers bearing a bristle arrangement and moveably attached to the brush-head carrier and driven in oscillation by the drive rocker, and a drive-coupler affixed to at least one of the bristle carriers and coupled to the drive rocker. The head can include two separately mounted bristle carriers, supporting bristle arrangements, which are driven about different movement axes by the drive rocker to enhance the cleaning action of the toothbrush.

A toothbrush head of an electric toothbrush, the toothbrush extending longitudinally and including a hand part, the hand part including a drive rocker, the toothbrush head being connectable to the hand part, the toothbrush head comprising:
- a brush-head carrier;
- a main bristle carrier and an additional bristle carrier, both bristle carriers bearing a bristle arrangement, the bristle carriers moveably attached to the brush-head carrier and driven in oscillation by the drive rocker;
- and
- drive-couplers extending from each of the bristle carriers configured to each engage the drive rocker when the toothbrush head is connected to the hand part to move the bristle carriers substantially transversely to the longitudinal direction of the toothbrush.
A toothbrush head of an electric toothbrush, the toothbrush extending longitudinally and including a hand part, the hand part including a drive rocker, the toothbrush head bringing connectable to the hand part, the toothbrush head comprising:
- a brush-head carrier;
- a main bristle carrier and an additional bristle carrier, both carriers bearing a bristle arrangement, the bristle carriers moveably attached to the brush-head carrier and operably linked to the drive rocker;
- and
- drive-couplers extending from each of the bristle carriers configured to each engage the drive rocker when the toothbrush head is connected to the hand part such that the drive rocker drives the main bristle carrier in rotational oscillation about a center axis and the additional bristle carrier in translational oscillation along a direction transverse to the toothbrush when the drive rocker defines a double cone shaped circulatory path.
