    摘要: The head of a powered toothbrush includes a first tuft block mounted for rotational oscillation about an axis generally perpendicular to the outer surface of the head, and a second tuft block having fixed bristles or bristles independently movable by being mounted on an elastomeric base. The second tuft block oscillates perpendicular to a longitudinal axis of the head and in an in and out direction perpendicular to the outer surface of the head. A third stationary block may also be mounted on the head of the powered toothbrush. The bristles on the first, second, and third tuft blocks may be of various lengths, colors and stiffness, and may be mounted perpendicularly to or at an angle to the outer surface of the head.
