Vibrating toothbrush
First Claim
1. A vibrating toothbrush, comprising:
- a rotatable motor;
a rotatable magnet attached to the motor, the rotatable magnet having a plurality of alternating pairs of magnetic poles; and
a lever arm having a first end positioned adjacent the rotatable magnet and a second end opposite the first end, wherein a permanent magnet is disposed on the first end of the lever arm, wherein rotation of the motor rotates the rotatable magnet, and a position of the plurality of alternating pairs of magnetic poles changes relative to the permanent magnet, wherein the first end of the lever arm having the permanent magnet thereon oscillates relative to a longitudinal axis of the toothbrush.

Abstract
A vibrating toothbrush includes a power source with a charging coil or bobbin wrapped thereabout. The power source is attached to a motor that is directly and rotatably connected to a rotatable magnet. The rotatable magnet has a plurality of alternating pairs of magnetic poles and is adjacent a permanent magnet. The permanent magnet is disposed on a first end of a lever arm with a brush attached to the other end of the lever arm. The rotation of the motor causes the rotatable magnet to rotate. The alternating polarity of the magnetic poles on the rotating magnet results in the permanent magnet oscillating, which in turn oscillates the lever arm and vibrates the brush on the second end of the lever arm.

9. A vibrating toothbrush, comprising:
-
a hollow case;
a rotatable motor;
a rotatable magnet attached to the motor, the rotatable magnet having a plurality of alternating pairs of magnetic poles;
a main stem having a first end positioned adjacent the rotatable magnet and a second end opposite the first end, wherein a permanent magnet is disposed on the first end of the main stem; and
a biasing member disposed around the main stem, a first end of the biasing member being attached to the permanent magnet and a second end of the biasing member being attached to an inner surface of the case, wherein the motor rotates the rotatable magnet, and a position of the plurality of alternating pairs of magnetic poles changes relative to the permanent magnet, wherein the first end of the main stem having the permanent magnet thereon oscillates relative to a longitudinal axis of the toothbrush and the biasing member dampens the oscillation of the main stem. - View Dependent Claims (10, 11, 12, 13, 14, 15, 17, 18, 19, 20, 21, 22, 23)

16. A vibrating toothbrush having a power source that provides a current to a rotatable motor, the toothbrush comprising:
-
a rotatable magnet attached to the motor, the rotatable magnet having a plurality of alternating pairs of magnetic poles; and
a lever arm having a first end positioned adjacent the rotatable magnet and a second end opposite the first end, wherein a permanent magnet is disposed on the first end of the lever arm, wherein rotation of the motor rotates the rotatable magnet, and a position of the plurality of alternating pairs of magnetic poles changes relative to the permanent magnet, wherein the first end of the lever arm having the permanent magnet thereon oscillates relative to a longitudinal axis of the toothbrush.
