8 results about "Sidestream smoke" patented technology

Sidestream smoke is smoke which goes into the air directly from a burning cigarette, cigar, or smoking pipe. Sidestream smoke is the main component (around 85%) of second-hand smoke (SHS), also known as Environmental Tobacco Smoke (ETS) or passive smoking. The chemical constituents of sidestream smoke are different from those of directly inhaled ("mainstream") smoke. Sidestream smoke has been classified as a Class A carcinogen by the U.S. Environmental Protection Agency.

Cigarette sidestream smoke particulate matter puff-by-puff trapping device and method

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.
