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.

A hygienic appliance combination comprising: a housing; a source of liquid associated with said housing; delivery means coupled to said housing for launching pulses of said liquid to a point of impact; and a pump located within said housing and coupled to accept said liquid and provide pulses of said liquid into said delivery means, said pump including: enveloping means defining an elongated central bore of predetermined length; at least one solenoid winding positioned to deliver magnetic flux into the interior of said bore; a plunger of magnetic material sized to slide within said bore and of a length less than said predetermined length; a chamber defined in said pump; means for inletting liquid from said source into said chamber; means for outletting liquid from said chamber into said delivery means; check valve means effectively disposed in the path of flow of said liquid for permitting flow of said liquid at least primarily in the direction from said source, through said chamber and out of said delivery means; reciprocating means coupled into said chamber for alternately effecting the drawing of said liquid into said chamber and propelling said liquid from said chamber through said outletting means into said delivery means; means disposed within said housing and adjacent to said chamber for indirectly slaving movement of said reciprocating means to movement of said plunger; means for cyclically energizing said one winding to move said plunger and said reciprocating means each in a given direction; and means for urging said plunger and said reciprocating means each in a return direction opposite said given direction.
