Publication number: 20040158944Abstract: A powered toothbrush provides movement of cleaning elements which replicate the preferred method of cleaning teeth, namely up-and-down movement on the surface of the user's teeth. This preferred movement is obtained by translating rotational movement of a motor, first into reciprocation movement within the toothbrush through the interaction of a cam follower and helical tracks, and then translation of the reciprocating movement into oscillating movement of the cleaning elements through a limited arc. The translation of rotational to reciprocating movement is achieved through interaction of a cam follower in a helical track. The translation of reciprocating movement to oscillating movement is achieved through reciprocating movement of a volute through a mating groove in the head of the toothbrush.Type: ApplicationFiled: November 4, 2003Publication date: August 19, 2004Inventor: Joseph Edward Fattori

Patent number: 6766549Abstract: A toothbrush system using a combination of mechanical force and fluid dynamics to increase the efficiency of plaque removal from the teeth and gums. The toothbrush includes a head unit with an irrigator nozzle and a hydraulically actuated and continuously variable bristle platform which negotiates the complex surface geometry found in the mouth of a user. The irrigation nozzle is powered by the pulsing of an anti-microbial irrigant which gives the toothbrush head unit the distinguishing ability of being able to “feel” the contour of the teeth and to “find” the spaces between them. Once the sensing irrigator nozzle finds the spaces between the teeth, it extends into the area, and releases the anti-microbial liquid directly into the space. The configured bristle tufts of the head unit automatically adjust their position for cleaning under the gum line, between the teeth, as well as flat surfaces.Type: GrantFiled: April 17, 2002Date of Patent: July 27, 2004Inventor: Michael F.
