Cigarette with reduced smoke temperature and improved flavor
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). In the smoke
backflow section, a flow distance of the smoke is increased, and a
heat exchange among hot airflow, the airflow baffles (5) and inner
walls of the smoke backflow section reduces a smoke
temperature.
