L'appareil de génération d'aérosol comprend : un module de résonance (12) qui comprend une bobine de détection (L1), la bobine de détection (L1) étant au moins partiellement située dans un champ magnétique d'un élément chauffant (30) ; un module de commande (11), qui est utilisé pour commander le module de résonance (12) afin de fonctionner dans un état de résonance, déterminer la fréquence de résonance du module de résonance (12) en fonction d'un signal de tension de la bobine de détection (L1) et déterminer un résultat de détection correspondant en fonction de la fréquence de résonance. Étant donné qu'une fonction de détection correspondante peut être obtenue sans fournir un capteur de température, le problème de la conception structurale de l'appareil de génération d'aérosol étant limité peut être résolu. De plus, étant donné que la bobine de détection (L1) n'a pas besoin d'être électriquement connectée à l'élément chauffant (30), le problème de difficultés de nettoyage provoquées par une connexion électrique est également résolu.
