  • Patent number: 8695143
    Abstract: The toothbrush includes a drive assembly comprising a DC motor (12) driven by a battery (15) with a rotating drive shaft (16) extending from one end of the DC motor, on which is mounted an eccentric member (20) which rotates with the drive shaft. A spring assembly (24) includes a hub member (26) at a proximal end, a mount member (28) at a distal end and a V-spring member (41) mounted to and extending therebetween. The DC motor is fixed to a rear surface of the hub member, the motor and the hub member being free to move in unison in operation of the toothbrush. The mount member is fixed in position in the toothbrush. A brushhead shaft (38) is mounted to and extends between the hub member and the mount member and extends distally from the mount member. The brushhead shaft member is offset laterally from the axis of rotation of the motor drive shaft. A brushhead assembly (42), including a set of bristles (44), is removably mounted on the brushhead shaft.

  • Patent number: 8661596
    Abstract: A toothbrush drive includes a first drive component for generating a magnetic field and a second drive component driven in both a translational and rotational manner under the influence of the magnetic field. A transmission element is deflected out of a predetermined position for transmission of both translational and rotary movement of the second drive component. The deflection of the transmission element varies along its longitudinal axis. A transmission element can be deflected out of a predefined position for transmission of a translatory movement and a rotational movement of the second drive component to the brush element along a longitudinal axis of the transmission element. The deflection of the transmission element out of the predefined position is varied along the longitudinal axis of the transmission element.

  • Patent number: 8631531
    Abstract: A device and method for brushing all surfaces of all of a user's teeth simultaneously. The device comprises bristle strip surfaces that envelope all of a user's teeth, the bristle strips comprising bristle bundles that scrub all surfaces of a user's teeth due to a reciprocating motion of the bristle strips. To use the device, a user inserts the toothbrush bristle strips into their mouth so to engage the user's teeth. A power source, motor, and drive assembly are utilized to cause the bristles to reciprocate, cleaning all a user's teeth surfaces simultaneously.

  • Patent number: 8572790
    Abstract: One embodiment of an actuator system for a power dental cleaning appliance to produce a tapping motion of bristle tufts in a dental cleaning appliance includes a plurality of piston elements (16) mounted in a brushhead for movement away from and then toward the brushhead (12). Bristle tufts (20) are positioned on the piston elements and move sequentially against and away from the teeth to produce a cleaning action. A low frequency fluid pressure action (40) in the range of 1-6 Hz maintains conformity of the bristle tufts in a low frequency sequence against the teeth, while a higher frequency fluid pressure action (42) in the range of 100-300 Hz moves the bristle tufts at that frequency to produce a tapping bristle action on the teeth to produce cleaning. In another embodiment, an actuation system includes an elongated actuator member (52) made of elastic material which expands and contracts about its longitudinal axis at a selected frequency by fluid pressure.
