Abstract

This invention relates to a battery powered electric toothbrush whose toothbrush head can vibrate laterally relative to the longitudinal axis of the toothbrush. The electric toothbrush comprises a handle containing a drive head eccentrically mounted to a motor shaft, a toothbrush head, and a sleeve intermediate the toothbrush head and the handle accommodating a swing arm. The swing arm has a head portion adjoining the toothbrush head pivotally attached in the forward end of the sleeve and has a tail portion provided with a transverse groove receiving the drive head. The head portion of the swing arm is bent to facilitate itself in contact within the forward end of the sleeve to minimize the impact on the motor power as a user presses the toothbrush head in a daily tooth cleaning. The toothbrush head is attachable, sealed, and secured to the drive portion with a flexible collar member.
