At the same time, the heating end of the semiconductor thermoelectric element can heat the pods in the heating chamber, and the pods can be obtained more fully and more efficiently. The uniform heating improves the atomization effect of the tobacco material. The invention has the advantages that the temperature of the cigarette rod is not hot to the hand, the temperature of the flue gas can be reduced, and the smoke effect is good.
