Abstract

L'invention concerne un atomiseur (1) et un dispositif d'atomisation électronique. L'atomiseur (1) comprend une base d'atomisation (15), un noyau d'atomisation (16) et un élément d'étanchéité (30). La base d'atomisation (15) comprend une base d'atomisation supérieure (151) et une base d'atomisation inférieure (152), et la base d'atomisation supérieure (151) et la base d'atomisation inférieure (152) forment ensemble une cavité d'installation (153) ; le noyau d'atomisation (16) est disposé dans la cavité d'installation (153) ; l'élément d'étanchéité (30) est disposé entre le noyau d'atomisation (16) et la base d'atomisation supérieure (151) ; et, dans la direction de la hauteur du noyau d'atomisation (16), l'élément d'étanchéité (30) expose au moins une surface latérale du noyau d'atomisation (16) à un passage d'écoulement d'air. De cette manière, la taille de l'atomiseur (1) peut être réduite dans la direction de l'épaisseur sans affecter l'efficacité de chauffage du noyau d'atomisation (16), et la sensation en bouche de l'aérosol atomisé est bonne.
