An electric toothbrush having bristle driven pulsation includes a brush head having a bristle holder and bristle tufts attached to the bristle holder. The bristle tufts and corresponding bristles are disposed at a perpendicular and/or a non-perpendicular angle with respect to a mounting surface of the brush head. The electric toothbrush also includes an electric toothbrush handle removably attached to the brush head. The electric toothbrush handle includes a linear motor configured to drive the bristle holder via a gearing structure coupled to the linear motor and the bristle holder. The linear motor causes the bristle holder to rotate clockwise and counterclockwise at a rotation frequency which exceeds a rotation frequency threshold (e.g., 100 Hz, 120 Hz, etc.). The linear motor also causes the brush head to vibrate in a direction toward and away from a contact surface in synchronization with the rotation of the bristles.

Bristle driven pulsation

Head for electric toothbrush

A toothbrush head or a brush carrier having at least one carrier element including at least one shape-shifting tuft mounted thereon. The shape-shifting tuft raises from a mounting end on a mounting surface of the carrier element generally along an extension direction towards a free end of the shape-shifting tuft. The shape-shifting tuft has a length from the mounting base to the free end and comprises a plurality of fibers. The shape-shifting tuft has a first cross-section having a first cross sectional area and shape at a first length along the extension direction, and a second cross-section having a second cross-sectional area and shape at a second length along the extension direction, wherein the first cross-sectional area and the second cross-sectional area are substantially identical and the first cross-sectional shape and the second cross-sectional shape are different so that the first cross-sectional shape does not match the second cross-sectional shape independent from an angle by which the first cross-sectional shape is rotated and independent from a displacement of the first cross-sectional shape.

Toothbrush head or brush carrier

A cleaning element carrier for a toothbrush in a form of a disk has a back surface including a central depression covering at least 70% of the back surface and forming an edge at the border. The carrier's front surface includes at least one protrusion so that the front surface comprises two levels, wherein the area covered by the depression is larger than the area covered by the protrusion.
