Dans un état initial non activé, l'élément de blocage (3) est situé à une position initiale dans laquelle un trou de guidage de liquide sur le tube d'atomisation (2) peut être bloqué, et joue un rôle dans le blocage du trou de guidage de liquide du tube d'atomisation (2), de telle sorte qu'une cavité de stockage de liquide (14) est dans un état fermé, un élément de guidage de liquide, un élément chauffant et similaire ne peuvent pas tremper dans un substrat de formation d'aérosol pendant une longue période, et une fuite de liquide peut être empêchée. Au moment de l'utilisation, il suffit d'insérer une tête d'atomisation (4) dans le tube d'atomisation (2) par un trou de montage, et la tête d'atomisation (4) peut entraîner, lorsqu'elle se déplace vers le haut le long de la direction axiale du tube d'atomisation (2), l'élément de blocage (3) à se déplacer de la position initiale à une position d'alimentation en liquide dans laquelle le trou de guidage de liquide (23) est ouvert, de telle sorte que la cavité de stockage de liquide (14) soit dans un état d'alimentation en liquide dans lequel le substrat de formation d'aérosol peut être fourni à la tête d'atomisation (4). De cette manière, lorsque l'ensemble de stockage de liquide n'est pas activé, la cavité de stockage de liquide (14) peut être dans l'état fermé par blocage du trou de guidage de liquide (23) à l'aide de l'élément de blocage (3).
