Abstract

La présente invention concerne un atomiseur et un dispositif d'atomisation électronique. L'atomiseur comprend une coque dans laquelle est formée une cavité de stockage de liquide, un manchon disposé dans la coque, un noyau d'atomisation disposé dans le manchon et un élément d'étanchéité disposé entre le noyau d'atomisation et le manchon. Un canal d'entrée de liquide, permettant à la cavité de stockage de liquide d'être en communication de drainage avec le noyau d'atomisation, est formé dans l'élément d'étanchéité et le manchon, et un canal de ventilation pour faire communiquer la cavité de stockage de liquide avec l'extérieur est formé entre l'élément d'étanchéité et le manchon. Au moins une partie d'une face de paroi externe de l'élément d'étanchéité est en ajustement étanche avec une face de paroi interne du manchon, de telle sorte que le canal d'entrée de liquide est séparé du canal de ventilation, empêchant ainsi le canal de ventilation d'affecter le canal d'entrée de liquide. Le canal de ventilation est situé à l'extérieur de l'élément d'étanchéité, ce qui permet de réduire considérablement un impact sur la structure du canal de ventilation en raison de la déformation du noyau d'atomisation, d'une surface externe irrégulière, etc., de façon à obtenir un canal de ventilation fixe et un processus de ventilation stable. De plus, un ensemble recouvert de coton n'est pas nécessaire, l'efficacité de production est améliorée, l'ensemble de fabrication est simple et la production automatique est facilitée.
