Abstract

L'invention concerne un atomiseur (1) et un dispositif d'atomisation électronique (100). L'atomiseur (1) comprend un boîtier (11), une base d'atomisation (12) et un corps chauffant (13) ; la base d'atomisation (12) est disposée dans le boîtier (11), et la base d'atomisation (12) forme, conjointement avec le boîtier (11), une cavité de stockage de liquide (10). La base d'atomisation (12) est pourvue d'une cavité de montage (120). La base d'atomisation (12) est pourvue d'un évidement inférieur pour liquide (1211), et une paroi latérale de l'évidement inférieur pour liquide (1211) est pourvue d'une ouverture (1211a) en communication avec la cavité de montage (120). Le corps chauffant (13) est disposé dans la cavité de montage (120), et le corps chauffant (13) est en communication fluidique avec la cavité de stockage de liquide (10) au moyen de l'évidement inférieur pour liquide (1211) et de l'ouverture (1211a). L'évidement inférieur pour liquide (1211) possède une structure de guidage, et dans la direction opposée à l'ouverture (1211a), la structure de guidage accroît progressivement l'espace de l'évidement inférieur pour liquide (1211) de façon à guider des bulles dans la direction opposée à l'ouverture (1211a), empêchant ainsi les bulles de bloquer l'ouverture (1211a), permettant d'assurer une alimentation en liquide suffisante et empêchant en outre la combustion à sec du corps chauffant (13).
