Abstract

Un atomiseur pour une cigarette électronique et une cigarette électronique sont divulgués. L'atomiseur pour la cigarette électronique comprend un tube de cartouche, une base et un canal d'échange de gaz. Le tube de cigarette est pourvu d'une cavité de stockage de liquide ; la base est disposée dans le tube de cigarette et est reliée au tube de cigarette, un espace d'atomisation et un trou de ventilation sont disposés dans la base, et le trou de ventilation est utilisé pour guider un gaz externe dans l'espace d'atomisation ; le canal d'échange de gaz fait communiquer l'espace d'atomisation avec la cavité de stockage de liquide, et le canal d'échange de gaz est pourvu d'un élément d'aération de gaz et de blocage de liquide de façon à permettre au gaz externe d'entrer dans la cavité de stockage de liquide et à empêcher le e-liquide dans la cavité de stockage de liquide de s'écouler vers l'extérieur ; une paroi latérale externe de la base est pourvue d'une rainure de stockage de liquide, et la rainure de stockage de liquide comprend une section droite d'admission de liquide et une section d'extension incurvée ; la section d'entrée de liquide est en communication avec l'espace d'atomisation ; la section d'extension est reliée à la section d'admission de liquide ; et le coin de la section d'extension est en forme d'arc, de façon à réduire la résistance à l'écoulement du e-liquide, ce qui facilite l'écoulement du e-liquide condensé dans la rainure de stockage de liquide et évite le blocage de la rainure de stockage de liquide.
