Les orifices de guidage d'air (3412) sont disposés sur le support de montage (341) du noyau d'atomisation (34), et l'air extérieur peut pénétrer dans une cavité de stockage de liquide ou le coton de stockage de liquide (35) au moyen des orifices de guidage d'air (3412), de sorte qu'on peut interdire efficacement la présence d'un gaz dans un espace poreux du coton de guidage de liquide (3421), et le liquide dans le coton de guidage de liquide (3421) est guidé de manière plus complète et uniforme, permettant ainsi d'améliorer le goût et la durée de vie du dispositif d'atomisation à base de coton de stockage de liquide (35).
