    Abstract: A cigarette with a reduced smoke temperature and an improved flavor includes a tobacco section (1), a filter section, and a smoke backflow section arranged between the tobacco section (1) and the filter section. An inlet hole (3) is provided at the smoke backflow section near the tobacco section (1) and intercommunication with the tobacco section (1). An outlet hole (6) is provided at the smoke backflow section near the filter section and intercommunicated with the filter section. Multiple airflow baffles (5) are staggered up and down inside the smoke backflow section and form a smoke backflow channel (4) which is sinuous. A first end of the smoke backflow channel (4) is intercommunicated with the inlet hole (3), and a second end of the smoke backflow channel (4) is intercommunicated with the outlet hole (6). Smoke enters the smoke backflow section from the inlet hole (3), and then passes through the smoke backflow channel (4).
