Patent Description:
With increasing attention of consumers to health and increasing demand for personalized experiences of cigarette products, the tobacco industry has continuously responded to upgrading of consumers' needs, various smoking products with tar reduction have been developed so as to bring less harm to consumers. Among which, because of different heating methods compared with traditional cigarette products, heat-not-burn cigarettes can provide a healthier smoking experience while meeting consumers' sensory needs for cigarette products.

The existing aerosol generating products mainly include the smoking core-material section, the supporting section, the cooling section and the filter-rod section, wherein, the supporting section not only supports the smoking products, but also gathers smoke and assists the cooling section to cool the smoke. The tube wall of the supporting section as well as the forming paper and the tipping paper wrapping the tube wall are perforated to form an air vent by online laser drilling in the prior art, so that external air enters the supporting section and mixes with smoke, thereby increasing smoke amount and effectively reducing smoke temperature, however, such cooling effect on smoke and mixing effect of air and smoke are still insufficient, the reasons are as follows: <NUM>. the radial support of the tube wall of the supporting section is insufficient, and the tube wall collapses to the center of the tube cavity after being subjected to external force, resulting in blockage of airflow channel for circulating air and smoke, leading to insufficient smoke volume; <NUM>. as the contact area between the smoke and the tube wall of the supporting section is limited, effective cooling cannot be achieved; <NUM>. due to short stay of smoke and air in the supporting section, as well as the smoke and air entering the cooling section through direct and quick passing through the supporting section, full mixing cannot be achieved; <NUM>. as the smoke directly contacts the tube wall of the supporting section, and the smoke passing through the supporting section has not been effectively cooled, the smoke temperature is high and the tube wall is too hot to hold in hand.

Thus, in order to further realize cooling of smoke, the cooling materials in the cooling section are mainly improved or the amount of cooling materials is directly increased, however, as most of the cooling materials are phase-change materials, after a few suctions, the phase-change materials may collapse and block the airflow channel, thus greatly increasing suction resistance, which affects smoking experience.

Besides, the existing aerosol generating products are generally flavored by tobacco materials, filters and cigarette paper, the flavor loading process is difficult, inefficient with unstable flavor release.

In the existing aerosol generating products, flavored beads are usually placed into the filter, and consumers break the beads manually before smoking, to release its internal flavoring substances, which can flavor aerosols during smoking; however, the problem are that, since beads have been completely crushed to release flavoring substances before smoking, resulting in strong flavor in the early stage of smoking, which is significantly weakened later with almost no flavoring effect in the end. However, the disadvantages of flavor loading through tobacco materials or cigarette paper are that, due to strong volatility of many flavors, characteristic aromas are easily lost after users open the package, resulting in poor aroma quality of the last cigarettes of each package.

The aerosol generating product of the present disclosure is suitable for circumferential and central aerosol generating product smoking set.

The present disclosure has the following beneficial effects compared with the prior art:.

The advantages of rupture of flavoring capsules by heating are as follows: ①By taking advantage of the flavoring capsule <NUM> is provided at the end of the supporting section <NUM>, which is adjacent to the end of the smoking core-material section <NUM>, if it is in other sections, the temperature is not high enough for beads to rupture; ②beads are mostly added to the acetate filter section in the prior art, as resilience of the wall of the supporting section is far less than that of acetate, acetate may rebound after pinching beads, there is almost no deformation; if beads rupture by pinching wall of the supporting section, the supporting section may deform, so that the structure of the supporting section and the airflow channel may be changed, affecting smoking effect and bringing bad experiences, while beads rupturing by heat can perfectly solve such problem; ③The capsule wall of flavoring capsule <NUM> can further reduce smoke temperature.

Further, the reasons and advantages that the flavoring capsule <NUM> is placed at the end of the supporting section <NUM> in the downstream of the smoking core-material section <NUM> in the present disclosure, which is adjacent to the end of the smoking core-material section <NUM>, rather than inside the smoking core-material are as follows: when consumers are smoking, the temperature of the core-material section is the highest, which is <NUM>, if the flavoring capsule <NUM> is placed in the core-material section and wrapped by the smoking material, the flavoring capsule <NUM> may be subjected to continuous high temperature during smoking, the capsule wall of the flavoring capsule <NUM> ruptures rapidly, and flavors and fragrances inside quickly volatilize, leading to strong feeling at first few suctions and almost no feeling at the latter suctions. Moreover, due to high temperature of the flavoring capsule <NUM>, although the capsule wall is indeed more likely to rupture, there are flavors and fragrances with low volatilization temperature inside the flavoring capsule <NUM>, such as menthol, orange oil, rose essential oil, etc., leading to a dilemma that the capsule wall needs a certain temperature to rupture, and flavors in the capsule wall with low volatilization temperature may volatilize instantaneously when the temperature is too high.

The flavoring capsule <NUM> is placed at the end of the supporting section <NUM> in the downstream of the smoking core-material section <NUM>, which is adjacent to the end of the smoking core-material section <NUM> in the present disclosure, which is inside the flavoring channel of the supporting section <NUM>, as the end of the supporting section <NUM> is close to the smoking core-material section <NUM>, the smoke generated by the smoking core-material section <NUM> still has a high temperature when it enters the hollow airflow channel, which can make the flavoring capsule <NUM> rupture. However, due to the flavoring capsule <NUM> is in the flavoring channel of the supporting section <NUM>, beads do not directly contact with hot aerosol, but transfer heat through the flavoring channel wall, to ensure that beads do not burst and release all fragrances in an instant by strong heat, but slowly release fragrances by slow heating, so as to achieve the effect of stable and sustained release of aroma.

With reference to the structure of the supporting section, the permeable hollow section <NUM> in the downstream of the supporting section is perforated in the present disclosure, so that an air vent is formed to introduce air, rather than perforating on the wall of the supporting section <NUM> as in the prior art, the reasons and effects are as follows: without perforating in the supporting section <NUM> to introduce air can first ensure that the flavoring capsule <NUM> inside the supporting section <NUM> can rupture and add flavor with enough smoke temperature, after the smoke has been initially cooled and flavored, air is further introduced from the permeable hollow section <NUM>, which can further cool and gather smoke. The smoking core-material section <NUM> of the present disclosure is wrapped by anti-seepage cigarette paper <NUM>, moisture in the smoking material seeps to the outside of the cigarette paper tube during storage of cigarettes and produces yellow spots; thus, it is necessary to add a water-proof layer to the inner wall of the cigarette paper tube filled with smoking materials. The water-proof layer can prevent moisture in the smoking material from seeping to the outside of the cigarette paper tube.

Similarly, smoking agents and other substances are added to the smoking material, during long-term placement, smoking agents in the smoking materials may carry flavors and fragrances to seep to the outside of the paper tube, resulting in yellow spots and affecting appearances of paper tubes, as smoking agents are oily, it is necessary to add an oil-proof layer to the inner wall of the cigarette paper tube filled with smoking materials. The oil-proof layer can prevent smoke agents in the smoking material from carrying flavors and fragrances to the outer wall of the paper tube and occurrence of yellow spots.

More importantly, a flavoring capsule <NUM> is placed at the end of the supporting section <NUM> in the downstream of the smoking core-material section <NUM> in the present disclosure, which is adjacent to the end of the smoking core material section <NUM>, thus, the forming paper <NUM> has an anti-seepage layer on one side that is close to the supporting section <NUM>, during smoking, after the capsule wall ruptures, fragrances inside the flavoring capsule <NUM> may also penetrate into the wall of the supporting section <NUM>, while the anti-seepage layer can prevent flavors and fragrances from seeping to the forming paper.
