Abstract: The invention relates to a brush part (1) for an electric toothbrush. Said brush part (1) is provided with a support tube (2) which accommodates a detachable shaft (3). This detachable shaft is arranged so that it is able to turn around a longitudinal axis (4) and can also be driven. Said shaft is also provided with a driving feature (24) positioned excentrically to said longitudinal axis (4). The brush part (1) is provided with a brush support (8). Said brush support (8) is arranged so that it can turn around a transversal axis (10), and is provided with a pick-up (22) which is positioned excentrically to the transversal axis and which is connected to the driving feature (24). A turning movement (5) of the detachable shaft (3) around the longitudinal axis (4) effects a turning movement (25) of the brush support (8) around the transversal axis (10). The detachable shaft (3) and the brush support (8) are braced against one another and/or against the support pipe (2) by means of spring elements in order to avoid rattling noises when the electric toothbrush is in operation.

Abstract: An automated dental cleaner (320) comprises a subassembly (324) having a pair of pivotally supported spaced tines (336) for supporting a movable floss span (338) therebetween. A pair of capstans (346, 352) are provided for drivingly reciprocating the floss span. Floss supply and take-up spools (340, 342) are arranged for continuously replacing the span. A main assembly (322) includes a housing containing a motor-driven multi-function transmission for driving the capstans and take-up spool, and for reciprocating the tines vertically. The main assembly and the subassembly are detachably connectable to each other for expedient replacement of the subassembly by a user. An additional feature on each tine includes a bracing pad (424) shaped for bracing the fork on teeth and gums. Further included is a flosser head (516), detachably connectable to a motorized toothbrush driver (512). A fork portion (520) of the head includes a pair of spaced tines (524) for supporting a movable floss span (522) therebetween. Floss supply and take-up spools (530, 532) are rotatably mounted to the head for replacing the span. A bite device for dental flossers includes a bite member (710) having a bite surface (721) on one side and a stop guard (724) on an opposite side. The bite member is movably supported between the fork tines such that the member and the fork can move up and down relative to each other. The member is connected to the fork such that a user biting on the bite surface can drive the floss span through a tight interdental gap wherein the stop guard engages a user tooth adjacent the floss span to prevent over-travel of the span thereby preventing floss impact against user gums.

Abstract: The invention concerns an oscillating drive to at least one tooth-cleaning element (19), such as a brush head on an electric toothbrush with a drive unit (1). A first rotational motion about an axis (A2) is first derived from the rotational motion of the drive unit (1) which may be a drive shaft, for instance. This rotational motion is transformed into a cyclic linear motion (L) essentially at right angles to the rotational motion of the drive shaft and transmitted to the tooth-cleaning element (19) to produce at least a reciprocating motion of the tooth-cleaning element.

Abstract: 2106313 9310721 PCTABS00022 An electric toothbrush comprises a handle part (1) and a push-on brush (4). From one end of the handle part (1) there projects the end of a hollow shaft (3) in which a toothbrush arbor (9) is coaxially arranged, the push-on brush (4) being adapted to be pushed on to the toothbrush arbor (9). The push-on brush (4) has a rotatable tuft of bristles which may be driven by a longitudinally reciprocating connecting rod.

Abstract: A power toothbrush device (100) including a brush head member (104) having bristles and a drivetrain assembly (400, 800) having a drivetrain shaft (124, 824) configured to drive the brush head member. The drivetrain assembly includes a resonator (410, 810) configured to rotate about a central axis (A) to move the bristles in a first movement pattern; a resilient member (420, 820); a magnet (700A, 700B, 830A, 830B) connected with the resonator; and a conductor (710A, 710B, 840A, 840B). As the resonator rotates and the magnet moves toward the conductor in a first direction, a force is generated upon the magnet in a second direction that is opposite the first direction, and the force generated upon the magnet thereby causes a rotation of the resilient member about a second axis that is different than the central axis.

Abstract: A power toothbrush device (100) including a brush head member (104) having a set of bristles (116); a body portion (102) coupled with the brush head member; and a drivetrain assembly (122). The drivetrain assembly includes an actuator (840) configured to generate periodic linear movement and a drivetrain shaft (124, 824) configured to transmit the generated periodic linear movement to the brush head member. The set of bristles are configured to be driven in a first direction (TM) at an amplitude equal to or greater than 0.25 mm and less than 3 mm and a frequency equal to or greater than 0.25 Hz and less than 520 Hz in the first direction. The drivetrain shaft is further configured to periodically rotate the set of bristles in a second direction (SM) about a central axis of the power toothbrush device.
