Abstract

L'invention a pour but de fournir une configuration qui permet d'obtenir une génération d'aérosol efficace dans un dispositif d'inhalation de type à chauffage par induction. La solution selon la présente invention concerne un système de génération d'aérosol comprenant une partie de réception qui a un espace interne qui peut recevoir un article de génération d'aérosol qui contient une source d'aérosol, une bobine d'induction de type solénoïde qui génère un champ magnétique variable lorsqu'un courant alternatif est appliqué à celle-ci, et un suscepteur qui génère de la chaleur lorsqu'il est pénétré par le champ magnétique variable. La partie de réception a une ouverture qui permet à l'espace interne de communiquer avec l'extérieur, et l'article de génération d'aérosol est inséré dans l'espace interne par l'ouverture. Le suscepteur a une première partie et une seconde partie. La première partie est conçue pour faire saillie dans l'espace interne à partir d'une partie inférieure de la partie de réception qui est sur le côté opposé à l'ouverture. La seconde partie est la partie qui n'est pas la première partie, et est disposée à l'intérieur de la bobine d'induction.
