Abstract

La présente invention concerne un dispositif d'atomisation électronique et un atomiseur. L'atomiseur comprend un ensemble d'atomisation et un boîtier d'atomisation emmanché sur la périphérie d'au moins une partie de l'ensemble d'atomisation. L'ensemble d'atomisation comprend une base d'atomisation et un premier élément d'étanchéité emmanché sur la base d'atomisation et relié à demeure à la base d'atomisation. Le premier élément d'étanchéité est disposé entre la base d'atomisation et le boîtier d'atomisation de façon à provoquer une déformation élastique au moyen de l'action d'une force externe pour fixer hermétiquement la base d'atomisation et le boîtier d'atomisation. L'atomiseur implique un processus d'assemblage simple et nécessite de faibles coûts de fabrication ; le boîtier d'atomisation n'est pas susceptible de se desserrer et de rebondir ; et la coaxialité du boîtier d'atomisation et de l'ensemble d'atomisation est bonne.
