Abstract
The interproximal cleaning appliance includes a housing () and a spray applicator () extending therefrom for directing a spray of fluid droplets to the interproximal area. Within the housing is a spray-generating assembly () which includes a chamber, a movable piston () mounted therein, one-way inlets () for gas and fluid and an outlet (). A system () for moving the piston, such as a motor, operatively compresses a spring () which creates a partial vacuum in the chamber, allowing gas to flow into the chamber through the gas inlet. Release of the spring produces a stream of fluid droplets which flows out of the chamber through the applicator to the interproximal area.
