CIGARETTE WITH REDUCED TOBACCO VAPOR TEMPERATURE
FIELD OF THE INVENTION
[0001] The disclosure relates to the technical field of novel cigarettes, and
specifically a
cigarette with reduced tobacco vapor temperature.
BACKGROUND
[0002] The novel cigarette heated through external heating but not the
combustion of tobacco
can obviously reduce a large number of hazardous substances generated during
the
combustion of the cigarette, so that the harm of passive smoking for non-
smoking population
is reduced. In the novel cigarette heated through an external heat source, one
important
constituent part is a cigarette of the heated cigarette, and the cigarette is
a tobacco product
capable of releasing a vapor aerosol under low temperature heating conditions.
The tobacco
product reaches an atomization temperature at the temperature of 200 to 400
DEG C in
general, the temperature of high temperature atomization vapor entering oral
cavity through a
filter tip can be higher than the temperature of ordinary cigarette
combustion.
