The interproximal cleaning appliance includes a housing (12) and a spray applicator (16) extending therefrom for directing a spray of fluid droplets to the interproximal area. Within the housing is a spray-generating assembly (14) which includes a chamber, a movable piston (26) mounted therein, one-way inlets (42, 40) for gas and fluid and 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 the spring produces a stream of fluid droplets which flows out of the chamber through the applicator to the interproximal area.

L'invention concerne un dispositif de nettoyage interproximal qui comprend une enceinte (12) et un appareil de pulvérisation (16) s'étendant depuis le dispositif pour orienter des gouttelettes de liquide pulvérisées vers la zone interproximale. L'enceinte accueille un ensemble pulvérisateur (14) qui comporte une chambre, un piston mobile (26) monté dans cette chambre, des admissions unilatérales (42, 40) pour gaz et fluide et une sortie (44). Un système (54) de déplacement du piston, du type moteur, agit en opération pour comprimer un ressort (32) qui crée un vide partiel dans la chambre, permettant au gaz de s'écouler dans la chambre via l'admission de gaz. La libération du ressort engendre un flux de gouttelettes de liquide qui s'écoule hors de la chambre via le pulvérisateur en direction de la zone interproximale.
