Abstract

An electric toothbrush is provided. The electric toothbrush has a handle, a head with a carriers and a longitudinal axis, and a neck disposed between the handle and the head. A motor is disposed within the handle. A shaft is operatively connected to the motor. The shaft is operatively connected to the carrier to move the carrier in a first motion. The carrier is capable of moving in a second motion when subjected to user forces.

Claims (10)

1. An electric toothbrush, comprising:
a handle;

a head comprising a carrier and a longitudinal axis;
a neck disposed between said handle and said head;
a motor disposed within said handle; and a shaft operatively connected to said motor, wherein said shaft is operatively connected to said carrier to move said carrier in a first motion, and wherein said carrier is capable of moving in a second motion when subjected to user forces.
2. The electric toothbrush according to claim 1, wherein said head comprises a spring, and wherein said carrier is in operative communication with said spring.
3. The electric toothbrush according to claim 2, wherein said spring biases said carrier when said carrier moves in said first motion and biases said carrier when said carrier moves in said second motion.
4. The electric toothbrush according to claim 3, wherein said spring's bias upon said carrier is greater during said second motion than said first motion.
5. The electric toothbrush according to claims 2, 3, or 4, wherein said spring is a spring clip.
6. The electric toothbrush according to claims 3 or 4, wherein said spring does not substantially bias said carrier when said carrier moves in said first motion, and wherein said spring does bias said carrier when said carrier moves in said second motion.
7. The electric toothbrush according to claims 2, 3, or 4, wherein said spring is one or more flexible walls.
8. The electric toothbrush according to claims 3, 4, or 6 wherein said first motion is generally along said longitudinal axis of said head.
9. The electric toothbrush of claim 3, 4, or 6, wherein said first motion is generally transverse to said longitudinal axis of said head.
10. The electric toothbrush according to claims 3, 4, or 6, wherein said carrier comprises a flexible cam which allows for said first or said second motions to be complemented by user forces.
