摘要:
An electric toothbrush is provided. The electric toothbrush has an elongate body having a handle, a head, and a neck extending between the handle and the head. The body has an interior chamber with a motor. A shaft is operatively connected to the motor. A first movable bristle carrier is disposed on the head. The shaft is operatively connected to the first bristle carrier to impart motion thereto. The first bristle carrier has a first composite tuft formed from a plurality of closely spaced bristle tufts and a plurality of second bristle tufts. The second tufts have a height that is greater than a height of the first composite tuft. The bristles of the first composite tuft having free ends and the bristles of the second tufts having free ends. The total surface area of the bristles of the first composite tuft is greater than the total surface area of the bristles of the second tufts, and the plurality of second tufts are disposed adjacent a portion of a perimeter of the composite tuft to form a first recessed region.

An electric toothbrush comprising a handle, a head, and a neck extending between the handle and the head. The electric toothbrush has a longitudinal axis. The handle has a hollow interior region, and has a motor disposed within the hollow region. The movable bristle holder is disposed on the head, and has a plurality of movable bristles disposed thereon. The drive shaft operatively connects the motor to the movable bristle holder to move the movable bristle holder and the bristles disposed on the movable bristle holder. The head has bristles disposed thereon. One or more bristles are disposed on a static portion of the head of the toothbrush. Movement of the drive shaft and/or the movable bristle holder results in movement of at least a portion of the one or more bristles disposed on the static portion of the toothbrush head.

An anti-loosening fastener includes a bolt including a head and a screw tail, a first washer configured to fit around the screw tail of the bolt, a first nut configured to screw onto the screw tail of the bolt, a second nut configured to screw onto the screw tail of the bolt, a first cutting surface located on the screw tail of the bolt. A first surface of the first washer includes one or more wedge-shaped helical teeth, and a first surface of the first nut includes one or more wedge-shaped helical teeth. The bolt, the first washer, the first nut, the second nut, and the cutting surface are capable of affixing a component. The anti-loosening fastener may also include a second cutting surface located on the screw tail of the bolt.

An actuator assembly and packaging feature for an electric toothbrush is disclosed. The actuator assembly includes a positionable member accessible along the outer surface of the toothbrush body. The actuator assembly further includes a spring member retained within the interior of the toothbrush body which urges a cam member against the underside of the positionable member. The positionable member defines an aperture extending through its midsection within which is disposed a depressible member. The depressible member has an outer end which is also accessible along the outer surface of the toothbrush body. Upon pressing the depressible member, the cam member and spring are urged against an electrical circuit provided within the body of the toothbrush which is used to selectively operate a motor and drive mechanism to move one or more sets of bristles. The actuator assembly additionally includes a feature of providing a raised region along an outer surface of the positionable member which guards against accidental or unintentional depressing of the depressible member. The packaging feature relates to a member formed in a package cover that is suitably sized and positioned over the depressible member of the actuator so that the cover, when pressed, may momentarily activate the toothbrush within the package.
