Description

TECHNICAL FIELD

The present disclosure relates to the technical field of aerosol generating products, and in particular, to an aerosol generating product with flavoring in supporting section.

BACKGROUND

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: 1. 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; 2. as the contact area between the smoke and the tube wall of the supporting section is limited, effective cooling cannot be achieved; 3. 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; 4. 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 present disclosure is proposed to solve the problems above.

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:

1. The supporting section 2 of the present disclosure is provided with a hollow airflow channel 22 and a plurality of flavoring channels 21; the plurality of flavoring channels 21 surround the outer side of the hollow airflow channel 22, and one end of the flavoring channels 21 that is closed to the smoking core-material section 1 is closed, and the other end that is close to the permeable hollow section 3 is open, a flavoring capsule 11 is provided within the flavoring channel 21. That is, the airflow channel of supporting section 2 is divided into two types: one is the hollow airflow channel in the center for aerosol circulation, the other is a flavoring channel on the periphery, one end of the channel that is close to the smoking core-material section 1 is plugged, that is, the aerosol generated by heating of the smoking core-material section 1 cannot enter the flavoring channel. When hot aerosol flows through the hollow airflow channel 22, beads in the flavoring channel 21 rupture by heat, releasing aroma substances, and flowing along the flavoring channel to the permeable hollow section 3. The advantages of such structure are as follows:
1. (1) Beads do not directly contact with hot aerosols, but transfer heat through the wall of the flavoring channel, so as to ensure that beads may not explode by strong heat and release all flavors in an instant, but slowly release flavor by heat;
2. (2) As there is no hot smoke circulation in the flavoring channel 21, the flavoring channel 21 forms an air-insulation layer to prevent the supporting section wall from directly contacting the smoke and causing external surface temperature to be too high;
3. (3) Beads in the flavoring channel 21 rupture by heat, releasing aroma substances and flowing along the flavoring channel to the permeable hollow section 3, as an air vent 31 is provided on the permeable hollow section 3 that axially runs through the wall of the permeable hollow section 3, external air enters the permeable hollow section through the air vent, external air first contacts with the surrounding fragrance vapor to condense it into small droplets, and contacts with the central mainstream smoke, the small fragrance droplets can be used as condensation nucleation points to promote condensation of smoke droplets around the fragrance droplets, forming a core-shell structure in which the smoke droplets wrap the fragrance droplets, rather than a disordered mixing of fragrance droplets and smoke droplets, resulting in long and lasting feeling of users.
2. The flavoring capsule 11 is placed at the end of the supporting section 2 in the downstream of the smoking core-material section 1, which is adjacent to the end of the smoking core-material section 1 for the first time in the present disclosure, the capsule wall of the flavoring capsule 11 is selected from materials that can rupture at an ambient temperature of 150-200°C, so that aroma substances inside the flavoring capsule 11 may not release due to protection of the capsule wall when suction is not performed, and the flavoring capsule is placed in the flavoring channel 21 of the supporting section 2, due to the protection of the wall of the supporting section 2 and the forming paper 5, loss of aroma substance during long-term placement can be further avoided. Besides, the flavoring capsule 11 of the present disclosure is different from the existing beads, which requires consumers to pinch to release flavoring substances inside, instead, the material that can rupture at an ambient temperature of 80-200°C is selected as the capsule wall, when consumers are smoking, temperature of the core-material section is the highest, which is 120°C, when hot aerosol flows through the hollow airflow channel 22, beads in the flavoring channel 21 rupture by heat, releasing aroma substances and flowing along the flavoring channel to the permeable hollow section 3.

The advantages of rupture of flavoring capsules by heating are as follows: ①By taking advantage of the flavoring capsule 11 is provided at the end of the supporting section 2, which is adjacent to the end of the smoking core-material section 1, 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; (3)The capsule wall of flavoring capsule 11 can further reduce smoke temperature.
Further, the reasons and advantages that the flavoring capsule 11 is placed at the end of the supporting section 2 in the downstream of the smoking core-material section 1 in the present disclosure, which is adjacent to the end of the smoking core-material section 1, 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 120 °C, if the flavoring capsule 11 is placed in the core-material section and wrapped by the smoking material, the flavoring capsule 11 may be subjected to continuous high temperature during smoking, the capsule wall of the flavoring capsule 11 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 11, although the capsule wall is indeed more likely to rupture, there are flavors and fragrances with low volatilization temperature inside the flavoring capsule 11, 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 11 is placed at the end of the supporting section 2 in the downstream of the smoking core-material section 1, which is adjacent to the end of the smoking core-material section 1 in the present disclosure, which is inside the flavoring channel of the supporting section 2, as the end of the supporting section 2 is close to the smoking core-material section 1, the smoke generated by the smoking core-material section 1 still has a high temperature when it enters the hollow airflow channel, which can make the flavoring capsule 11 rupture. However, due to the flavoring capsule 11 is in the flavoring channel of the supporting section 2, 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 3 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 2 as in the prior art, the reasons and effects are as follows: without perforating in the supporting section 2 to introduce air can first ensure that the flavoring capsule 11 inside the supporting section 2 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 3, which can further cool and gather smoke.
3. The smoking core-material section 1 of the present disclosure is wrapped by anti-seepage cigarette paper 12, 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 11 is placed at the end of the supporting section 2 in the downstream of the smoking core-material section 1 in the present disclosure, which is adjacent to the end of the smoking core material section 1, thus, the forming paper 5 has an anti-seepage layer on one side that is close to the supporting section 2, during smoking, after the capsule wall ruptures, fragrances inside the flavoring capsule 11 may also penetrate into the wall of the supporting section 2, while the anti-seepage layer can prevent flavors and fragrances from seeping to the forming paper.

4. The supporting section 2 of the present disclosure is provided with a flavoring channel 21 and a permeable airflow channel 22, wherein the flavoring channel 21 is used for flavoring and the permeable airflow channel 22 is used for gathering smoke. A flavoring capsule 11 is provided in part of the flavoring channel 21, and the flavoring capsule 11 is close to one side of the smoking core-material section 1, so as to control adding amount of the flavoring capsule 11. The permeable airflow channel 22 can be used to gather smoke, reduce adsorption of smoke and increase smoke amount. Moreover, the flavoring channel 21 is dispersed outside the permeable airflow channel 22, so that flavoring is uniform.
5. The aerosol generating product of the present disclosure also includes a supporting section 2 with a hollow structure, wherein, the supporting section can not only support the aerosol generating product, more importantly, it can gather smoke and reduce smoke temperature, to solve the problem of high temperature entering mouths of smokers.
6. An air vent 31 is provided on the permeable hollow section 3 of the present disclosure, when the air vent 31 of the present disclosure is consistent with shape and size of the holes drilled on the supporting section in the prior art, the air vent 31 is closer to smokers' mouths, and suction at the air vent 31 is significantly greater than that at the hole drilled on the supporting section in the prior art, thus, the air vent 31 of the present disclosure has better ventilation effect with a larger amount of ambient air introduced, so as to reduce smoke temperature. Meanwhile, the supporting section 2 of the present disclosure is provided with a cavity, the permeable hollow section 3 is also provided with a cavity, the air introduced can be better mixed with smoke to further reduce smoke temperature. The cooling section rather than the supporting section is perforated in the present disclosure, further using the change of suction to increase air intake and reduce smoke temperature.

The aerosol generating product sample 1 and the aerosol generating product sample 2 are smoked in the same conditions in conjunction with HNB cigarette smoking set, during smoking, the smoking core-material section 1 of the aerosol generating product is 200°C. Sensory evaluation of aerosol generating products is carried out by a plurality of evaluators based on the following six indicators: smoke amount, fragrance, strength, harmony, irritant and taste; score ranges of the six quality indicators are as follows: smoke amount 0-10 points, fragrance 0-30 points, strength 0-10 points, harmony 0-10 points, irritant 0-15 points, taste 0-25 points, the total score is 100 points, the higher the scores of five evaluation indicators including smoke amount, fragrance, strength, harmony and taste, the stronger the feeling of evaluation indicators during smoking, the higher the score of irritant evaluation indicator, the less obvious sensation of such evaluation indicator during smoking, while the higher total score of the six evaluation indicators, the better smoking sensation of aerosol generating products. Wherein, sensory evaluation scores of the aerosol generating product sample 1 and the aerosol generating product sample 2 are shown in table 1.
The basis is Q/YNZYJ07.022. Table 1 Sensory evaluation scores of various aerosol generating products during smoking

Sample Smoke amount 10 Fragrance 30 Strength 10 Harmony 10 Irritant 15 Taste 25 Total 100

Sample 1 9.0 26.5 9.0 8.5 12.0 22.0 87.0
