Abstract

La présente invention concerne un appareil d'atomisation électronique, ainsi qu'un atomiseur et un ensemble d'atomisation associés. L'ensemble d'atomisation comprend un noyau d'atomisation, deux feuilles d'électrode recouvrant une partie de la surface du noyau d'atomisation et un manchon isolant emmanché à l'extérieur du noyau d'atomisation et des deux feuilles d'électrode. Le noyau d'atomisation comprend un corps d'absorption de liquide et un corps chauffant disposé sur le corps d'absorption de liquide. Deux électrodes du corps chauffant sont respectivement connectées électriquement aux deux feuilles d'électrode. En recouvrant une partie de la surface du noyau d'atomisation avec les deux feuilles d'électrode, la résistance du noyau d'atomisation dans un processus d'assemblage peut être davantage augmentée tandis qu'une connexion électrique est obtenue, de sorte que le noyau d'atomisation n'est pas facilement écrasé par compression lors d'un processus de montage.
