Abstract
The brushhead (14) includes a neck portion (15) which connects at a proximal end thereof to a handle portion (12) of a power toothbrush (10). At the distal end of the neck portion is a brush member (16, 28) which includes a bristle base plate (18, 34) and a bristle field (20, 36) mounted thereon. An eccentric (30) is mounted for spinning action on the bristle base plate, positioned in the midst of the bristle field. An eccentric bristle field (38) is mounted on the eccentric. The motion of the brush member produced by a toothbrush drive assembly creates a spinning motion of the eccentric and the eccentric bristle field mounted thereon, resulting in additional oral cleaning action.
Claims12
A brushhead (14) for use with a power toothbrush (10) having a handle portion (12) and a drive assembly (22) positioned therein, the brushhead comprising:
- a neck portion (15), the proximal end of which is connectable to the handle portion of the toothbrush;
- a brush member (16, 28) having a bristle base plate (18, 34) and a first bristle field (20, 36) mounted thereto, positioned at a distal end of the neck portion, wherein in operation, the drive assembly moves the brush member and the first bristle field in a selected oscillating or other oral care motion;
- and
- an eccentric (30), mounted for rotation on the bristle base plate, wherein the motion of the brush member imparts a spinning motion to the eccentric and an eccentric bristle field (38) mounted thereon, to assist in oral care action of the toothbrush.
