Abstract

L'invention concerne un appareil d'atomisation électronique (100) et un procédé de commande de chauffage associé, et un support de stockage informatique. Le procédé de commande de chauffage consiste à : dans une première étape, commander un corps chauffant (50) pour qu'il effectue un chauffage à une première puissance ; et dans une seconde étape, commander le démarrage d'une source de gaz (40), de telle sorte qu'une buse (30) pulvérise des gouttelettes atomisées sur le corps chauffant (50), et commander le corps chauffant (50) pour qu'il effectue un chauffage à une seconde puissance, la seconde puissance étant supérieure à la première puissance. Avant le démarrage de la source de gaz (40), le corps chauffant (50) est d'abord préchauffé à la première puissance, laquelle est relativement faible, et lorsque la source de gaz (40) est démarrée, le corps émetteur de chaleur (50) est chauffé à la seconde puissance, laquelle est relativement élevée, de façon à compenser une perte de température du corps chauffant (50) qui est provoquée lorsque des gouttelettes atomisées atteignent le corps chauffant (50), et le corps chauffant (50) peut rapidement s'élever jusqu'à une température cible, de telle sorte que le corps chauffant (50) puisse également obtenir un meilleur effet d'atomisation dans une étape initiale.
