ABSTRACT:
A toothbrush system is provided which includes a handle member (14) which defines an internal handle chamber (22) for containment therein of a cleansing liquid container (28). The handle member (14) is coupled to a head housing (24) which has bristles (20) extending from it. The bristles (20) are displaceably oscillated about a central axis (16) and simultaneously are rotated about an axis which extends in a perpendicular direction to the longitudinal direction (18) and is responsive to the oscillating displacement of the bristles (20). A mechanism is provided for delivering a liquid from the handle (14) through the head member (12) and external the toothbrush system adjacent the bristles (20). In this manner, there is provided pulsating liquid flow from the toothbrush system with a combined rotation and oscillation of the toothbrush bristles (20) in a plurality of planes.
