Abstract

Un ensemble de chauffage et un dispositif de génération d'aérosol sont divulgués dans la présente invention. L'ensemble de chauffage comprend une unité de chauffage et au moins deux éléments électromagnétiques. L'unité de chauffage est conçue pour générer de la chaleur par induction d'un champ magnétique et chauffer un substrat de génération d'aérosol ; l'unité de chauffage comprend au moins deux sous-unités de chauffage et une partie de liaison qui est reliée entre les sous-unités de chauffage adjacentes ; chaque sous-unité de chauffage a une cavité de réception destinée à recevoir un segment du substrat de génération d'aérosol ; et lesdits éléments électromagnétiques sont agencés de façon à correspondre auxdites sous-unités de chauffage, et sont conçus pour fournir le champ magnétique. Au moyen de l'agencement susmentionné, une commande segmentée pour la température de l'unité de chauffage est obtenue, ce qui permet en outre d'améliorer l'expérience d'utilisation d'un utilisateur.
