摘要：
A dental cleaning appliance such as an electric toothbrush includes a handle body 16, a fluid delivery system with an extendable rinse nozzle 36 for delivering bursts of working fluid to the teeth of a user and a brush unit with bristles 32 mounted on a bristle carrier which extends at least partially about the nozzle 36 and is driven for movement relative to the nozzle. The nozzle 36 is biased for movement relative to the brush unit from a retracted proximal position to an extended distal position, urged against the users teeth in use, with a burst of fluid conveyed through a fluid conduit system 230,232 in the stem 26 and through the nozzle 36 upon a sensor detecting movement of the nozzle 36 entering an interproximal gap to dislodge matter therein. The fluid may be pumped from a refillable reservoir surrounding the stem into an accumulator which has a solenoid valve controlling the bursts fluid to the nozzle based upon the sensor output.
