Lorsque le produit de production d'aérosol est chauffé, le matériau d'absorption de rayons infrarouges absorbe les rayons infrarouges utilisés pour le chauffage par rayonnement du substrat de formation d'aérosol. Par rapport à un produit de chauffage sans combustion classique, le produit de production d'aérosol présente une température réduite de l'aérosol, en particulier une température réduite de l'aérosol du premier vapotage, et présente un taux de variation augmenté de la valeur de TPM, améliorant ainsi l'expérience de vapotage d'un utilisateur. En même temps, après l'augmentation de la température du matériau d'absorption de rayons infrarouges, le matériau d'absorption de rayons infrarouges peut également chauffer et atomiser le substrat de formation d'aérosol, ce qui permet d'améliorer l'efficacité de chauffage du produit dans une certaine mesure.
