Dentifrice dispensing electrical toothbrush with integrated dispensing platform and self sealing spout

摘要

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.

主权项

1. A dentifrice dispensing electrical toothbrush comprising: a. a handle having a reservoir containing a dentifrice material and a driver-pump head including: i. a pumping chamber having a side opening attached with an actuator, ii. a driving chamber including a drive shaft and a means of imparting oscillatory motion to the drive shaft, iii. a dispensing platform attached with a slit spout receiving dentifrice material from said reservoir when the actuator is depressed, said dispensing platform being an extended portion of said driver-pump head, b. a replaceable brush unit attached to said dispensing platform, said brush unit comprising: i. a first brush element having a first base attached with bristles, said first base having a notch driven in oscillatory motion by said drive shaft, ii. a second brush element having a second base attached with bristles, said second base having a spout opening for inserting with said slit spout to receive the dentifrice material dispensed from said slit spout, and said brush unit being detachable from said dispensing platform while the dentifrice material is being enclosed inside said slit spout.
