Abstract
An oral hygiene appliance combination has a housing into which liquid is fed and from which liquid is delivered into the mouth of the user. A pump within the housing is of a solenoid-actuated type and includes a chamber that inlets and outlets the liquid to be applied under the pumping action. A flexible diaphram, which effectively forms part of the chamber, sustains the pumping action. Movement of that diaphram is coupled to movement of the solenoid plunger. At least one solenoid winding is cyclically energized to move the plunger and the diaphram in connection with the pumping action.
