Abstract

L'invention concerne un système de génération d'aérosol et un dispositif de génération d'aérosol (100). Le dispositif de génération d'aérosol (100) comprend un corps chauffant (31), un canal d'écoulement de gaz (70) et une chambre de stockage de gaz (4120) ; le corps chauffant (31) a une chambre de chauffage (310) et est utilisé pour générer de la chaleur de façon à chauffer un substrat de formation d'aérosol (200) reçu dans la chambre de chauffage (310), un espace étant laissé entre le corps chauffant (31) et le substrat de formation d'aérosol (200) ; la chambre de stockage de gaz (4120) est disposée au niveau d'une extrémité du substrat de formation d'aérosol (200), est en communication avec le substrat de formation d'aérosol (200), et est utilisée pour stocker un gaz ; le canal d'écoulement de gaz (70) est au moins partiellement formé dans l'espace entre le corps chauffant (31) et le substrat de formation d'aérosol (200), et est en communication avec la chambre de stockage de gaz (4120).
