The invention relates to the technical field of cigarette manufacturing, and discloses a
sidestream smoke particulate matter
trapping unit and method. The device comprises a sidestream
flue gas particulate matter
trapping unit which comprises a fishtail cover, a sidestream
flue gas filter disc trap used for
trapping particulate matter of sidestream
flue gas and a sampling pump used for providing power for suction of the sidestream
flue gas, which are sequentially connected in series; the main
stream smoke particulate matter capturing unit comprises a cigarette holder and a suction power source, the cigarette holder and the suction power source are sequentially connected in series, the cigarette holder is used for fixing cigarettes, and the suction power source is used for generating suction power for the cigarette holder. According to the technical scheme, a trapping mechanism of puff-by-puff correspondence is established, it is ensured that
sidestream smoke released within the
specific time period can be instantly and independently collected while each puff simulates suction, and therefore the technical problem that in the prior art, only whole-process collection can be conducted, and different numbers of suction puffs cannot be distinguished is solved.
