摘要：
The interproximal cleaning appliance includes a housing (12) and a sprayapplicator (16) extending therefrom fordirecting a spray of fluid droplets to the interproximal area. Within thehousing is a spray-generating assembly (14) which includes a chamber, amovable piston (26) mounted therein, one-way inlets (42, 40) for gas and fluidand an outlet (44). A system(54) for moving the piston, such as a motor, operatively compresses a spring(32) which creates a partial vacuum in the chamber,allowing gas to flow into the chamber through the gas inlet. Release of thespring produces a stream of fluid droplets which flowsout of the chamber through the applicator to the interproximal area.
