This invention discloses an extraction device for heated cigarette aerosol components and a method for determining the moisture content of heated cigarette aerosols. The extraction device mainly consists of a collector, a container, and a peristaltic pump. The collector is connected in series with the container and the peristaltic pump via a flexible tube. The main body of the collector is formed by a sealed connection of components A and B, which together form an extraction chamber within the collector. Components A and B are respectively provided with interfaces A and B communicating with the extraction chamber. A filter is placed between interfaces A and B within the extraction chamber. This extraction device can directly capture aerosols released during the smoking process of heated cigarettes using the collector, and can efficiently extract components from the aerosols without opening the collector, reducing the loss of the analyte components in the aerosols during the collection and extraction process, thus minimizing the impact on the measurement results.

This invention provides a combustion-type heated cigarette with adjustable combustion rate. The heated cigarette includes a combustion section, a core section, and a filter section coaxially connected in sequence. The combustion section, core section, and filter section are formed by wrapping the combustion section with cigarette paper. The cigarette paper wrapping the combustion section is a cigarette paper with adjustable combustion rate, and the cigarette paper with adjustable combustion rate is a cigarette paper coated with inorganic powder. Under the condition of the same combustion section length, the heated cigarette of this invention, by wrapping the combustion section with specific cigarette paper, significantly extends the combustion time compared to conventional combustion-type heated cigarettes using ordinary cigarette paper, ensuring sufficient and sustained total heat output. The degree of pyrolysis of the tobacco material in the core section is significantly improved, and the smoke release is more complete and stable.

This invention relates to a method for improving the smoking stability of heated cigarettes using an internal and external coupling heating method, belonging to the field of heated cigarette technology. The method includes the following steps: heating the cigarette core using an internal and external coupling heating method. Initially, internal heating is the primary method. When the temperature of the heat source used for internal heating reaches the operating temperature, the temperature of the heat source used for internal heating and / or the temperature of the heat source used for external heating is adjusted to ensure that the volume of the portion of the cigarette core with a temperature greater than T / n increases uniformly. This method, by employing an internal and external coupling heating method and adjusting the temperature of the heat source used for internal heating and / or the temperature of the heat source used for external heating to achieve matching coupling of internal and external heating, aims to achieve a "slow release" of tobacco components in the cigarette core material, significantly improving the puff-by-puff release stability of the heated cigarette.
