Abstract

L'invention concerne un ensemble d'atomisation (1) et un dispositif d'atomisation électronique. L'ensemble d'atomisation (1) comprend un réservoir de stockage de liquide (13), une base d'atomisation (20) et un élément d'étanchéité (40). L'élément d'étanchéité (40) est emmanché sur un siège supérieur d'atomisation (21) et est associé à la paroi latérale externe de la base d'atomisation (20) pour former un conduit de ventilation. Une première extrémité du conduit de ventilation est en communication avec l'atmosphère extérieure, et une seconde extrémité du conduit de ventilation est en communication avec le réservoir de stockage de liquide (13), le conduit de ventilation se présentant sous la forme d'une structure de guidage unidirectionnel de flux, permettant à l'atmosphère extérieure d'entrer dans le réservoir de stockage de liquide (13) et empêchant le liquide présent dans le réservoir de stockage de liquide (13) de fuir. Le conduit de ventilation formé par l'association de la base d'atomisation (20) avec l'élément d'étanchéité (40) présente une grande stabilité de sa section et n'est que peu influencé par la tolérance des pièces et la tolérance d'assemblage, si bien que la régularité du conduit de ventilation est améliorée. L'élément d'étanchéité (40) ne doit isoler que la base d'atomisation (20), de telle sorte que la formation du conduit de ventilation est assurée indirectement, et les exigences concernant les performances et la taille de l'élément d'étanchéité (40) sont réduites. La structure de guidage unidirectionnel de flux empêche le liquide présent dans le réservoir de stockage de liquide (13) de fuir vers une cavité d'atomisation (23), ce qui permet d'améliorer les performances du dispositif d'atomisation électronique.
