Abstract

L'invention concerne un dispositif de formation d'aérosol (100) et un ensemble de chauffage (10). L'ensemble de chauffage (10) comprend : un élément chauffant (11), l'élément chauffant (11) étant une céramique conductrice, et l'élément chauffant (11) comportant une première extrémité (111) et une seconde extrémité (112) qui sont disposées à l'opposé l'une de l'autre ; une première électrode (14) reliée à la première extrémité (111) de l'élément chauffant (11) ; et une seconde électrode (15) reliée à la seconde extrémité (112) de l'élément chauffant (11). Lorsque l'élément chauffant (11) de la céramique conductrice est excité, l'élément chauffant (11) tout entier génère de la chaleur ; le champ de température est uniforme et la stabilité est bonne ; et l'élément chauffant (11) est d'une structure intégrée, et présente ainsi une résistance mécanique élevée et une bonne stabilité de résistance.
