Abstract

La présente invention concerne un atomiseur ultrasonore et une cigarette électronique. L'atomiseur ultrasonore comprend un ensemble de stockage de liquide (1), un ensemble de guidage de liquide (2) et une ensemble d'atomisation (3). Un compartiment de liquide (13) est disposé à l'intérieur de l'ensemble de stockage de liquide (1). L'ensemble d'atomisation (3) comprend une feuille d'atomisation ultrasonore (33). L'ensemble de guidage de liquide (2) est un élément de guidage de liquide céramique (21). La feuille d'atomisation ultrasonore (33) est placée verticalement. Une section supérieure de l'élément de guidage de liquide céramique (21) est en communication avec le compartiment de liquide (13). Une section inférieure de l'élément de guidage de liquide céramique (21) entre directement en contact avec au moins une surface d'atomisation de la feuille d'atomisation ultrasonore (33). Une région d'atomisation (331) de la feuille d'atomisation ultrasonore (33) est exposée sous l'élément de guidage de liquide céramique (21). Dans l'invention, un élément de stockage de liquide n'a pas besoin d'être disposé dans la région d'atomisation (331) de la feuille d'atomisation ultrasonore (33) parce qu'un e-liquide s'écoule directement vers la région d'atomisation (331) de la feuille d'atomisation ultrasonore (33) au moyen de l'élément de guidage de liquide céramique (21), de telle sorte qu'une atomisation ultrasonore puisse être activée rapidement et qu'une grande quantité de vapeur puisse être générée.
