METHOD AND APPARATUS FOR DEVICE FOR BRUSHING TEETH

摘要

An apparatus and method including a toothbrush head; toothbrush bristles fixed to the toothbrush head; and means for moving the toothbrush head in up and down directions and for simultaneously rotating the tooth brush head in a plane which is perpendicular to the up and down directions. The means for moving the toothbrush head in the up and down directions and for simultaneously rotating the tooth brush head in the plane which is perpendicular to the up and down directions may include a motor, a motor shaft, a disk, a swing arm, a post, and a pin. The apparatus may be configured so that the motor rotates the motor shaft causing the disk to rotate causing the pin to move in the up and down directions and causing the swing arm to rotate in the plane which is perpendicular to the up and down directions.

1. An apparatus comprising:
a toothbrush head; toothbrush bristles fixed to the toothbrush head; and means for moving the toothbrush head in up and down directions and for simultaneously rotating the tooth brush head in a plane which is perpendicular to the up and down directions; and wherein the means for moving the toothbrush head in the up and down directions and for simultaneously rotating the tooth brush head in the plane which is perpendicular to the up and down directions includes a motor, a motor shaft, a disk, a swing arm, a post, and a pin; wherein the apparatus is configured so that the motor rotates the motor shaft causing the disk to rotate which causes both the pin to move in the up and down directions and the swing arm to rotate in the plane which is perpendicular to the up and down directions; wherein the movement of the pin up and down causes the post to move up and down which causes the toothbrush head to move up and down; wherein the rotation of the swing arm in the plane which is perpendicular to the up and down directions causes the post to rotate in the plane which is perpendicular to the up and down directions which causes the toothbrush head to rotate in the plane which is perpendicular to the up and down directions; and wherein the disk includes first and second ramp portions which cause the pin to move in the up and down directions as the disk rotates.
