Description

An aerosol-generating product with fragrant support sections

Technical field

The present invention relates to the technical field of aerosol-generating products, and in particular to an aerosol-generating product with a supporting section scented.

Background technique

As consumers pay more attention to health issues and demand for personalized experiences in cigarette products, the tobacco industry continues to respond to the upgrading of consumer demands and develop various smoking products that reduce scorch and harm. Among them, heat-not-burn cigarettes can provide a healthier smoking experience while satisfying consumers' sensory needs for cigarette products because their cigarette heating method is different from traditional cigarette products.

Existing aerosol-generating products mainly include a smoking core material section, a support section, a cooling section and a filter section. The support section not only plays a supporting role in smoking products, but more importantly, it gathers smoke and assists the cooling section in protecting the smoke. The air cools down. The existing technology uses online laser drilling to penetrate the pipe wall of the support section, and the molding paper and tipping paper wrapping the pipe wall form ventilation holes, allowing outside air to enter the inside of the support section and mix with the smoke, thereby increasing the amount of smoke and effectively reducing the Flue gas temperature, but its cooling effect on flue gas and mixing effect of air and flue gas are still not good. The reasons are the following two points: 1. The radial support force of the pipe wall of the support section is insufficient, and the pipe wall is pushed backward by external force. The center of the tube cavity collapses, causing the airflow channel of flue gas and air to be blocked and the amount of smoke to be insufficient; 2. The contact area between the flue gas and the support section pipe wall is limited, and effective cooling cannot be achieved; 3. The flue gas and air are in the support section The residence time in the section is short, and the flue gas and air directly and quickly enter the cooling section through the support section, and full mixing cannot be achieved; 4. The flue gas directly contacts the pipe wall of the support section, and because the flue gas passing through the support section has not been effectively cooled, the smoke The temperature is too high, causing the pipe wall in this section to become hot. Therefore, in order to further cool down the flue gas, the current main focus is to improve the cooling materials in the cooling section or directly increase the amount of cooling materials. However, most of the cooling materials are phase change materials. After a few puffs, the phase change materials shrink. It collapses and blocks the air flow channel, greatly increasing the suction resistance and affecting the suction experience.

In addition, existing aerosol-generating products are generally flavored through tobacco materials, filters, and cigarette papers. The fragrance-carrying process is difficult, inefficient, and the flavor release is unstable. Existing aerosol-generating products usually place flavored exploding beads in the filter, and consumers manually pinch the exploding beads before smoking, thereby releasing the aromatic substances inside them, thus replacing the gas during inhalation. The sol has the aroma-enhancing effect, but the problem is that since the popping beads have been completely crushed before smoking, the aroma-enhancing substances inside are completely released. This results in a strong fragrance in the early stage of smoking, but in the subsequent smoking The aroma weakened significantly in the later period, and there was almost no aroma-enhancing effect. The disadvantage of using tobacco materials or cigarette paper to carry fragrance is that due to the high volatility of many spices, these characteristic fragrances are easily lost after the user opens the package, resulting in poor quality of the cigarettes at the end of each pack that have no fragrance.

In order to solve the above problems, the present invention is proposed.

The aerosol-generating product of the present invention is suitable for both circumferential-type aerosol-generating product smoking sets and central-type aerosol-generating product smoking sets.

Compared with the existing technology, the present invention has the following beneficial effects:

1. The support section 2 of the present invention has a hollow air flow channel 22 and a plurality of aromatic channels 21; a plurality of the aromatic channels 21 surround the outside of the hollow air flow channel 22, and the aromatic channels 21 are close to the One end of the smoking core material section 1 is blocked, while an end close to the breathable hollow section 3 is open. There is a fragrance capsule 11 in the fragrance channel 21 . That is to say, the air flow channels of the support section 2 are divided into two types. The first is a hollow air flow channel located in the center for aerosol circulation, while the second air flow channel is a perfuming channel located on the peripheral side. The side close to the smoking core material section 1 is blocked, which means that the aerosol generated by heating the smoking core material section 1 cannot enter the fragrance channel. When hot aerosol flows through the air flow channel 22, the popping beads in the perfuming channel 21 are heated and rupture, releasing fragrance substances and flowing along the perfuming channel to the breathable hollow section 3. The advantages of this structure are:

(1) The popping beads will not directly contact the hot aerosol, but will transfer heat through the wall of the aromatic channel. This can ensure that the popping beads will not explode and release all the spices due to strong heat in an instant, but will be slowly heated and released slowly. Plays the role of sustained release of spices;

(2) Since there is no hot smoke flowing in the aromatic channel 21, the aromatic channel 21 forms an air insulation layer to prevent the support section pipe wall from directly contacting the smoke, causing the outer surface temperature to be too high and scalding your hands;

(3) The popping beads in the perfuming channel 21 are heated and rupture, releasing fragrance substances and flowing along the perfuming channel to the breathable hollow section 3. Since the breathable hollow section 3 has a tube that radially penetrates the breathable hollow section 3 The outside air enters the breathable hollow section through the vent holes 31 on the wall. The outside air first contacts the spice vapor on the peripheral side to condense it into small droplets, and then contacts the mainstream smoke in the center. The small droplets of spice can be used as condensation The nucleation point promotes the condensation of smoke droplets around the flavor droplets, forming a core-shell structure in which the smoke droplets wrap the flavor droplets, instead of a disordered mixed structure of flavor droplets and smoke droplets, which makes the user feel the fragrance. Long lasting.

2. For the first time in the present invention, the aromatic capsule 11 is placed at the end of the downstream support section 2 of the smoking core material section 1 close to one end of the smoking core material section 1, and the wall of the aromatic capsule 11 is selected from A material that can rupture at an ambient temperature of 150-200°C. This means that when suction is not performed, due to the protection of the capsule wall, the fragrance substances inside the fragrance capsule 11 will not be released, and the fragrance capsule 11 is placed on the support In the aromatic channel 21 of section 2, due to the protection of the tube wall of section 2 and the molding paper 5, the loss of fragrance substances during long-term placement is further avoided. In addition, the flavored capsule 11 of the present invention is not like the existing popping beads, which requires consumers to pinch and break to release the aromatic substances inside. Instead, the capsule wall is selected from materials that can rupture at an ambient temperature of 80-200°C. When the consumer is smoking, the temperature of the cigarette core material section is the highest, around 120°C. When hot aerosol flows through the hollow air flow channel 22, the exploding beads in the aromatic channel 21 are heated and rupture, releasing flavor substances, and Flow along the perfuming channel to the breathable hollow section 3. The advantages of using the aromatic capsule to rupture when heated are: ① Take advantage of the advantage of the aromatic capsule 11 at the end of the support section 2 close to the end of the smoking core material section 1, if the temperature in other sections does not reach the rupture temperature; ② In the past, the exploding beads were mostly added to the acetate fiber filter section. Since the resilience of the pipe wall in the support section is far less than that of acetate fiber, the acetate fiber rebounds after pinching the exploding beads and has almost no deformation. However, if the pipe wall is pinched and blasted through the support section, Beads, the support section will be deformed, so that the structure of the support section and the air flow channel are changed, which affects the suction effect and brings a bad consumer experience. The heated rupture perfectly solves this problem; ③ The wall of the flavored capsule 11 is heated Rupture can further reduce the temperature of the flue gas.

Furthermore, the present invention places the aromatic capsule 11 at the end of the downstream support section 2 of the smoking core material section 1 close to one end of the smoking core material section 1 instead of placing the aromatic capsule 11 inside the smoking core material section 1 The reason and advantage of the capsule 11 is that when the consumer smokes, the temperature of the cigarette core material section is the highest, which is around 120°C. If the flavoring capsule 11 is placed in the cigarette core material section and wrapped by the smoking material, the temperature of the cigarette core material section will be the highest. During the smoking process, the flavored capsule 11 will be subjected to continuous high temperature, causing the wall of the flavored capsule 11 to rapidly rupture, and the flavors and fragrances inside to volatilize rapidly. This will lead to a strong aroma in the first few puffs, and a strong smoke in the subsequent puffs. There is almost no fragrance effect. On the other hand, due to the high temperature that the flavored capsule 11 is exposed to, although the capsule wall is indeed more likely to break, there are some flavors and fragrances with lower volatilization temperatures inside the flavored capsule 11, such as menthol, orange oil, rose essential oil, etc., so that This creates the dilemma that the capsule wall requires a certain temperature to rupture, but if the temperature is too high, the low volatilization temperature flavors and fragrances in the capsule wall will volatilize instantly.

In the present invention, the aromatic capsule 11 is placed at the end of the downstream support section 2 of the smoking core material section 1, which is adjacent to one end of the smoking core material section 1, and is placed in the aromatic channel of the support section 2. Due to the support This end of section 2 is close to the smoking core material section 1, so the smoke generated by the smoking core material section 1 still has a relatively high temperature when it first enters the medium air flow channel, which can cause the aromatic capsule 11 to rupture. Degree. However, since the flavoring capsule 11 is in the flavoring channel of the support section 2, the popping beads will not directly contact the hot aerosol, but will transfer heat through the wall of the flavoring channel, thus ensuring that the popping beads will not be instantly exposed to strong heat. Instead of bursting to release all the spices, they are slowly released by heat, thereby achieving a stable and slow-release aroma effect.

Combined with the structure of this support section, the present invention perforates the breathable hollow section 3 downstream of the support section 2 to form a ventilation hole for introducing air, instead of drilling holes on the tube wall of the support section 2 to introduce air like the prior art. In this way The reason and effect are: not punching holes in the support section 2 to introduce air can first ensure that the aromatic capsule 11 inside the support section 2 can have enough smoke temperature to rupture and aromatize, and after the smoke has initially cooled down and aromatized, it can be further The breathable hollow section 3 introduces air, which can further cool down and concentrate the smoke.

2. The smoking core material section 1 of the present invention is wrapped by anti-seepage cigarette paper 12. During the storage of cigarettes, the moisture in the smoking material seeps to the outside of the cigarette paper tube, causing yellow spots, so it is necessary to A waterproof layer is added to the inner wall of the cigarette paper tube filled with smoking material. The waterproof layer can prevent moisture in the smoking material from penetrating to the outside of the cigarette paper tube.

Similarly, smoke-generating materials will be added to the smoking materials. When placed for a long time, the smoking agents in the smoking materials will carry flavors and fragrances and penetrate into the outside of the paper tube, causing yellow spots and affecting the appearance of the paper tube. Due to the smoke The agent is oily, so it is necessary to add an oil-proof layer to the inner wall of the cigarette paper tube filled with smoking material. The oil-proof layer can prevent the smoking agent in the smoking material from carrying flavors and fragrances from penetrating into the outer wall of the paper tube and preventing the occurrence of yellow spots.

More importantly, the present invention places the aromatic capsule 11 at the end of the downstream support section 2 of the smoking core material section 1 close to one end of the smoking core material section 1, so the forming paper 5 is close to the support section 2 has an anti-seepage layer on one side. During the suction process, after the capsule wall ruptures, the fragrance substances inside the flavored capsule 11 may also penetrate into the support section 2 tube wall, and the anti-seepage layer can prevent flavors and fragrances from seeping into the forming paper. The problem.

3. The support section 2 of the present invention has a fragrance channel 21 and a hollow air flow channel 22. The fragrance channel 21 is used for fragrance, and the hollow air flow channel 22 is used to collect smoke. There is a fragrance capsule 11 at the end of the partial fragrance channel 21 close to the smoking core material section 1, and the amount of the fragrance capsule 11 can be controlled. The hollow air flow channel 22 can be used to collect smoke, reduce the adsorption of smoke, and increase the amount of smoke. On the other hand, the perfuming channels 21 are dispersed outside the hollow air flow channel 22, so the perfuming is more uniform.

4. The aerosol-generating product of the present invention also includes a support section 2 with a hollow structure. The support section can not only support the aerosol-generating product, but more importantly, it can gather the smoke and help reduce the temperature of the smoke to solve the problem of entering the aerosol-generating product. The temperature in smokers' mouths is high and the smoke burns their mouths.

5. There is a ventilation hole 31 on the breathable hollow section 3 of the present invention. When the shape and size of the ventilation hole 31 of the present invention is consistent with the hole drilled on the support section in the prior art, the distance between the ventilation hole 31 of the present invention and The smoker's mouth is closer, so the suction force at the vent hole 31 is significantly greater than the suction force at the hole drilled on the support section in the prior art. Therefore, the ventilation effect of the vent hole 31 of the present invention is better, and the amount of ambient air introduced is Larger, which is more conducive to reducing the flue gas temperature. At the same time, the cigarette support section 2 of the present invention has a cavity, and the breathable hollow section 3 also has a cavity. The introduced air can better contact and mix with the smoke, further reducing the temperature of the smoke. The present invention perforates the cooling section instead of the supporting section, thereby further utilizing changes in suction to increase air intake and reduce flue gas temperature.
