Abstract
Dentifrice dispensing electrical toothbrush comprising a driver-pump head with a dispensing platform, a replaceable brush unit and a handle having a battery and a cartridge containing dentifrice material. The replaceable brush unit includes a oscillatory brush element and a brush element having a circular or an elongated spout opening as well as a snap-on mounting bracket for fastening to the driver-pump head. The dispensing platform contains a flow channel and a self-sealing spout to prevent drying of the dentifrice material at the spout. The self-sealing spout opens and closes automatically during a pumping action. The brush element with a spout opening is detachably mounted over the spout fixed on the dispensing platform to allow for brush oscillation around the spout and receive the dentifrice material dispensed from the flow channel. Different drive mechanisms are used to impart rotary, lateral or longitudinal oscillation on a brush element in a brush unit.
