This invention relates to the field of heated cigarette technology, specifically disclosing a filter tip structure and molding method. The filter tip structure includes: a filter rod core, molding paper, and multiple plugs. The filter rod core is cylindrical, and the molding paper is fixedly sleeved on the outer circumferential surface of the filter rod core. The molding paper has multiple guide holes arranged in an array, with m rows along the circumference of the filter rod core and n columns along the axial direction of the filter rod core, where m and n are both integers greater than 0. The multiple plugs are arranged one-to-one with the multiple guide holes, and the plugs can block the guide holes. With this configuration, the smoker can manually remove the plugs before actually smoking. Removing the plugs increases the entry of side airflow, thereby increasing the ventilation rate of the heated cigarette and reducing the draw resistance during smoking. At the same time, removing the plugs can cause the microcapsules containing flavoring to rupture due to friction, releasing the flavoring and giving the smoke its characteristic aroma, effectively improving the smoker's smoking experience.

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.

The application discloses a method for improving the conversion rate of raspberryin in sidestream smoke, which comprises the following steps: mixing raspberryin and a certain amount of intumescent flame retardant, and adding the mixture to the burning position of a cigarette. The method can obviously improve the conversion rate of raspberryin converted into raspberry ketone in sidestream smoke.

The present application belongs to the technical field of tobacco, and discloses a method for improving the conversion rate of ethyl vanillin-beta-D-glucoside in sidestream smoke. In the method, ethyl vanillin-beta-D-glucoside and a certain amount of intumescent flame retardant are mixed and then added to the combustion position of a cigarette. The method can significantly improve the conversion rate of ethyl vanillin-beta-D-glucoside in sidestream smoke into ethyl vanillin.

The application discloses a kind of for cigarette side stream smoke evaluation device, including base and cover;Base includes base body, filter clamping mechanism and cigarette clamping mechanism, and base body is equipped with assembly part and air hole;Cover includes cover body and exhaust mechanism, and cover body is equipped with mounting part and exhaust window, and exhaust mechanism is matched with exhaust window;Cover body and base body form air cavity.The evaluation device for cigarette side stream smoke of the present application can evaluate the side stream smoke after it diffuses, and can effectively evaluate the influence of side stream smoke in the actual smoking process.Moreover, the evaluator can smell the Cambridge filter clamped by filter clamping mechanism according to the demand, or smell through exhaust window and exhaust mechanism, which is conducive to improving the accuracy of side stream smoke sensory evaluation.

The present invention belongs to the field of cigarettes, and particularly relates to a sealed heated cigarette that reduces sidestream smoke. The cigarette comprises, from upstream to downstream, a tobacco section (1) sealed at the upstream end, a low-resistance section (2), and a functional filter section (3) that are coaxially abutted in sequence, and the outside of the cigarette is wrapped with an external wrapper (4); wherein the low-resistance section (2) is a tube having an axial central cavity (2-1) and circumferential sidewall through-holes (2-2); the low-resistance section (2) further comprises a barrier layer (2-3) with a certain air permeability arranged on the circumferential sidewalls of the central cavity (2-1). The cigarette of the present invention is provided with a barrier layer covering the circumferential sidewalls of the central cavity and the sidewall through-holes in the low-resistance section. The barrier layer has a certain air permeability and does not affect the inflow of external air when inhaled; when not inhaled, smoke will not escape through the sidewall through-holes, thereby effectively reducing smoke loss.

The invention relates to the technical field of cigarette manufacturing, and discloses a puff-by-puff analysis device for the content of carbon monoxide in side-stream smoke of cigarettes, which comprises a side-stream smoke trapping and storing unit comprising a fishtail cover for collecting the side-stream smoke, a sampling pump for providing suction power for the side-stream smoke, and an air bag for storing the collected side-stream smoke; the gas phase substance analysis unit comprises a carbon monoxide analyzer for carrying out carbon monoxide concentration analysis on the flue gas sample, and a vacuum pump for pumping out gas in the gas bag and conveying the gas to the carbon monoxide analyzer; and the smoking simulation unit comprises a cigarette holder for fixing a cigarette and a smoking power source for simulating smoking of the cigarette in the cigarette holder. The device realizes active and complete trapping and targeted analysis of sidestream smoke, and overcomes the defect of dependence on environmental diffusion or manual operation in the prior art. Therefore, a reliable hardware foundation is laid for follow-up accurate puff-by-puff release rule analysis.
