摘要:
A powered toothbrush includes a plurality of rows of bristle tufts that project through a perforated top shell of a hollow toothbrush head. Ends of individual bristles are held in buckets to form the tufts and the bristle ends opposite the bucketed ends are free (where the opposite ends contact the toothbrush users teeth). The bucketed ends of the bristle tufts are captured within the internal space within the head but are not fixedly attached to any other toothbrush component or structure. This non-fixed attachment feature enables the bristle tufts to have multiple degrees of freedom (DoF) of motion with respect to the perforations in the top shell and can rotate, move axially, and tilt.
