  • Patent number: 10507092
    Abstract: A power toothbrush having a vibration compensation system, the toothbrush including a toothbrush housing (72), and an actuator which includes a stator (74) having a first moment of inertia and a rotor (76) having a second moment of inertia, at the end of said rotor is mounted a bristle member. A first spring element (86) having a first spring constant connects the stator to the housing, while a second spring element (88) having a second spring constant connects the rotor to the housing, wherein the ratio of the first and second spring constants is substantially the same as the ratio of the first and second moments of inertia.

  • Patent number: 9277980
    Abstract: The mouthpiece includes a plurality of individual thin layers of material forming a base or shell portion of the mouthpiece alternating with a plurality of individual bristle layers which are configured to the shape of bristles at the interior surfaces thereof. The base layers are comprised of a material which is sufficiently stiff to permit driving of the mouthpiece, while the bristle layers comprise material which is sufficiently flexible to produce an effective scrubbing action in operation without damage to the mouth tissues.

  • Patent number: 9049919
    Abstract: The toothbrush includes a brushhead (24) having a multi-layer bristle field assembly (30), which includes alternate thin base layers (32) and thin bristle layers (34) which are bonded together to form the bristle field assembly. The base layers provide support for the bristle field assembly while the bristle layers are configured to provide bristle elements therealong for brushing of the teeth.
