Abstract

L'invention concerne une cigarette à basse température qui comprend principalement les matières premières suivantes, en parties en poids : 90 à 110 parties d'un support de tabac; 5 à 45 parties d'un extrait d'épices; 0,2 à 5 parties d'une essence de cigarette; et 0,5 à 15 parties d'un agent d'atomisation, le support de tabac comprenant des feuilles de tabac et des tiges de tabac dans un rapport de masse de (5-10):(1-4). La cigarette à basse température présente une structure compacte et peut absorber davantage d'agents d'atomisation et générer une grande quantité de fumée; elle contribue favorablement à la conduction de la température de chauffage et raccourcit le temps d'attente d'un fumeur, ce qui en rend l'expérience de fumée plus proche de celle de la cigarette classique.
