Le manchon d'étanchéité, le noyau d'atomisation poreux, le support de limitation et le couvercle inférieur sont reliés de manière séquentielle et emmanchés à l'intérieur du boîtier de bas en haut à partir de l'ouverture du boîtier. Le manchon d'étanchéité, la paroi intérieure du boîtier et le tube d'inhalation de fumée définissent une cavité de stockage de liquide. L'extrémité supérieure du manchon d'étanchéité est pourvue d'un trou d'évent central relié au tube d'inhalation de fumée, la partie inférieure intérieure du manchon d'étanchéité est emmanchée sur le noyau d'atomisation poreux, la paroi latérale extérieure de la partie supérieure du manchon d'étanchéité est emmanchée sur la paroi latérale intérieure du boîtier, et la paroi latérale extérieure de la partie intermédiaire inférieure du manchon d'étanchéité est emmanchée sur la paroi latérale intérieure du support de limitation. La paroi latérale extérieure du support de limitation est reliée à la partie supérieure du couvercle inférieur. Le couvercle inférieur est conditionné dans l'ouverture du boîtier, et l'extrémité supérieure du couvercle inférieur est pourvue d'une cavité d'atomisation. La présente invention présente les effets bénéfiques suivants : un liquide atomisé qui n'a pas été atomisé n'est pas prélevé directement par le flux d'air et inhalé dans une bouche, ce qui permet d'améliorer considérablement l'expérience de l'utilisateur.
