In handle dispensing device

摘要

An oral hygiene apparatus produces a succession of water pulses at a predetermined pressure and those pulses are delivered to a handle shaped to be grasped by the human hand. An elongated nozzle projects outwardly from the handle, the shape of the handle permitting the water pulses to be directed against the teeth and gums of the user. A reservoir that forms part of the handle contains a liquid to be selectively dispensed along with the water pulses. The reservoir is coupled into communication with the flow path of the water pulses. A controllable valve selectively opens communication to enable the conveyance of the liquid into the flow path and in response to the receipt of the water pulses within the handle.
