Abstract

L'invention concerne un atomiseur électronique qui a un noyau d'atomisation en céramique en forme de V (3), ledit atomiseur comprenant un ensemble buse d'aspiration (1), un ensemble d'atomisation (2), un noyau d'atomisation en céramique en forme de V (3) et un ensemble de base (4). L'ensemble buse d'aspiration (1) est relié à l'extrémité supérieure de l'ensemble d'atomisation (2). L'ensemble de base (4) est relié à l'extrémité inférieure de l'ensemble d'atomisation (2). Le noyau d'atomisation en céramique en forme de V (3) comprend un boîtier (31), une couche d'absorption interne (32) en céramique microporeuse et un élément chauffant de type résistance (33), une électrode de contact de l'élément chauffant de type résistance (33), une cavité d'atomisation (320) dans la couche d'absorption interne (32), et un canal d'entrée d'air (314) relié à la cavité d'atomisation (320), un corps principal intermédiaire (310) du boîtier (31) étant conçu pour être de forme tronconique et être pourvu d'un trou traversant latéral (311) et de tuyaux de dérivation d'échappement et d'entrée d'air (312, 313). La couche d'absorption interne (32) est en céramique microporeuse, est conçue pour être de forme tronconique et est pourvue d'une saillie latérale (321). La saillie latérale (321) est insérée dans le trou traversant latéral (311) du corps principal intermédiaire (310) du boîtier (31). L'élément chauffant de type résistance (33) est de forme tronconique. Le canal d'entrée d'air (314) communique avec la cavité d'atomisation (320) au moyen de trous d'alimentation en air périphériques (316) dans un déflecteur (315), et le déflecteur (315) est situé dans le tuyau de dérivation d'entrée d'air (312) du boîtier (31). L'ensemble d'atomisation (2) présente les avantages d'empêcher une fuite de liquide et d'améliorer l'efficacité du chauffage et de l'atomisation.
