ABSTRACT:
A portable, or travel-type, oral hygiene appliance is provided with simplified and effective means for producing a pulsating, or intermittent, liquid jet; and optionally including a light stick for obtaining locally-concentrated illumination of areas within the mouth. The appliance is of lightweight and compact construction, in the form of an appliance casing having reduced vertical thickness and with a foldable water container carried on a portion of the upper surface of the casing. The pump for propelling a pulsating liquid jet uses a rotating member carrying spaced roller elements that move against a resilient, flexible, hose with a water column therein, to compress the hose between each roller and an abutment, thereby applying impeller force to spaced segments of the liquid column, so as to obtain an intermittent high pressure, liquid jet, discharge. Aspirated air is introduced into the water column upstream of the pump to aid in the interruption, or chopping, of the liquid column by the pump into pressurized pulses of liquid. A manually actuatable controller downstream of the pump operates to control volume discharge from the pump. A lighting stick, may be provided as an optional attachment, and is energized by the electrical supply for the appliance.
