Abstract

L'invention concerne une cartouche à chauffage sans combustion (1) comprenant : un corps tubulaire (10), le corps tubulaire (10) ayant une extrémité éloignée des lèvres et une extrémité à proximité des lèvres qui sont disposées à l'opposé l'une de l'autre ; une partie d'étanchéité (20), la partie d'étanchéité (20) étant utilisée pour obturer de manière étanche l'extrémité à l'opposé des lèvres ; une partie de génération de vapeur (30), la partie de génération de vapeur (30) étant logée dans le corps tubulaire (10), et la partie de génération de vapeur (30) étant disposée de manière adjacente à l'extrémité à l'opposé des lèvres ; une partie de refroidissement (40), la partie de refroidissement (40) étant logée dans le corps tubulaire (10) et étant disposée de manière adjacente à la partie de génération de vapeur (30), les parties de la partie de refroidissement (40) faisant face à l'extrémité à proximité des lèvres et faisant face à l'extrémité à l'opposé des lèvres étant chacune pourvues d'un espace de réception, et la partie de génération de vapeur (30) pouvant entrer dans l'espace de réception faisant face à l'extrémité à l'opposé des lèvres ; et une partie de filtration (50), la partie de filtration (50) étant logée dans le corps tubulaire (10) et étant disposée au niveau de l'extrémité à proximité des lèvres. La cartouche à chauffage sans combustion peut empêcher une résistance de vapotage excessive résultant d'un espace interne de la partie de génération de vapeur (30) devenant plus petit après l'insertion dans un dispositif de vapotage.
