Abstract

L'invention concerne un dispositif de nettoyage dentaire constitué d'une protection dentaire (1) et d'un manche (2). La protection dentaire (1) comprend une rainure supérieure pour dents (4), une rainure inférieure pour dents (5), et une partie liaison (6) liant les rainures supérieure et inférieure pour dents. Des pores ouverts (7) agencés selon des intervalles sont répartis sur les surfaces de parois internes des rainures supérieure et inférieure pour dents. Un premier cathéter (8) intégré dans la protection dentaire (1) est relié à une extrémité des pores ouverts (7). Un module pompe (9) est fourni à l'intérieur du manche (2). Le module pompe (9) comprend un orifice d'entrée de pompe (10) et un orifice de sortie de pompe (11). L'orifice de sortie de pompe (11) du module pompe (9) est relié au premier cathéter (8) s'étendant depuis l'intérieur des rainures dentaires à l'intérieur du manche (2). L'orifice d'entrée de pompe (10) du module pompe (9) est relié à un module réservoir d'eau (12) fourni sur le manche (2). Une unité d'atomisation ultrasonore (45) est fournie à l'intérieur du module réservoir d'eau (12). De l'eau dans le module réservoir d'eau (12) est atomisée par l'unité d'atomisation ultrasonore (45), transférée vers la protection dentaire (1), puis pulvérisée par l'intermédiaire des pores ouverts (7) sur les surfaces de parois internes des rainures pour dents. Le dispositif de nettoyage dentaire résout le problème lié aux effets de faible atomisation et aux effets de nettoyage insuffisant d'un dispositif de nettoyage dentaire précédent.
