Description
Technical Field
The invention belongs to the technical field of novel tobacco, particularly relates to a composite filter tip structure for heating a non-combustible tobacco product, and further discloses an aerosol cooling device with a filter tip.
Background
Various forms of aerosol-generating articles have been proposed in the known art, these articles being characterised by heating, but not burning, tobacco, generally at temperatures below 350 ℃, with only a small amount of second-hand smoke being generated during the heating of the aerosol-generating article, the resulting aerosol being less harmful and becoming a hotspot of current research.
Related products are known to use particles, cut tobacco and cut stems as smoking materials of non-combustible heated tobacco products, and due to the characteristics of the structures of the smoking materials, the smoking materials have poor performance of absorbing fluid substances containing volatile compounds, and heated contents are less, so that the smoking temperature is higher.
Among the known cooling techniques for heating non-combustible tobacco products, there are mainly axially arranged PLA folded sheets, hollow tube inner wall composite polymer films, and spiral PLA fasteners. The mode of compounding the polymer film on the inner wall of the hollow tube cannot provide a larger surface area for absorbing hot aerosol, and the flowing mode of the hot aerosol is linear, so that the cooling effect is not ideal; although the screw-type PLA fastener can extend the stroke distance of the hot aerosol, it causes a relatively large suction resistance, which affects the suction feeling.

In some embodiments, in order to achieve a better cooling effect of the flue gas, a mode of arranging a plurality of porous reducing cooling units can be adopted, and the passage of the flue gas is changed for a plurality of times, so that the cooling effect is more obvious; under the condition that the porous reducing cooling unit is added, the suction resistance is inevitably increased, the suction resistance can be reduced by arranging the plurality of hollow units, and meanwhile, the addition of different spice components in cigarettes can be met.
