Powered toothbrush
First Claim
1. In a powered toothbrush having a handle, a head mounted to said handle, a primary tuft block mounted in said head, said primary tuft block having exposed bristles extending outwardly from said head, a secondary tuft block mounted in said head at a location displaced from said primary tuft block, said secondary tuft block having exposed bristles extending outwardly from said head, a drive assembly in said handle, said drive assembly including a drive connection to said primary tuft block in the form of a direct drive from a shaft axially extending from a motor to said primary tuft block to oscillate said primary tuft block back and forth, and a drive transmitting connection connecting said primary tuft block to said secondary tuft block for moving said secondary tuft block back and forth in an oscillating manner in response to the movement of said primary tuft block while said primary tuft block is being oscillated, said drive transmitting connection comprising an inwardly extending section of said primary tuft block and an outwardly extending section of said secondary tuft block.

Abstract
A powered toothbrush refill head combines a typical round oscillating or primary tuft block which oscillates in a rotational manner with a secondary tuft block. The secondary tuft block may be oscillated in a rotational manner or may oscillate linearly back and forth in the same direction as the handle of the toothbrush. The secondary tuft block could be in the form of a pair of side by side plates mounted on the head adjacent to the round oscillating block. The invention could also be practice where the secondary tuft block is in the form of a plurality of sets of rows of bristles mounted for back and forth movement in a direction perpendicular to the handle.

46. In a powered toothbrush having:
-
a handle and a head mounted thereto, a driving tuft block having an outer periphery and mounted in said head along a first axis, a driven tuft block having an outer periphery and mounted in said head at a location and along a second axis that is displaced from said driving tuft block, a drive assembly in said handle, said drive assembly including a drive connection to said driving tuft block to oscillate said driving tuft block back and forth, and a drive transmitting connection connecting said driving and driven tuft blocks in the form of an inwardly extending section from the outer periphery of the driving tuft block that engages an outwardly extending section from the outer periphery on the driven tuft block for moving said driven tuft block back and forth in an oscillating manner in response to the movement of said driving tuft block. - View Dependent Claims (17, 18, 19, 20, 21, 47)
