Abstract

L'invention concerne une cartouche (100) pour un dispositif à fumer électronique, qui comprend une source de chaleur (107) comprenant un élément chauffant à ampoule encapsulée (109). La source de chaleur est disposée à l'intérieur d'un compartiment (106) de la cartouche. Le compartiment s'étend à partir d'un tube d'écoulement d'air (104). Le boîtier (101) comprend une zone de stockage (112) pour retenir un matériau à inhaler. La cartouche comprend un élément de liaison fileté (103) qui se fixe à une unité de commande qui a une alimentation électrique telle qu'une batterie. La cartouche évite un contact direct entre le matériau à inhaler et tout élément métallique de la cartouche, soit en éliminant les éléments métalliques soit en encapsulant les éléments métalliques dans du verre, du quartz ou de la céramique.
