Description

Technical Field

[0001] This application belongs to the field of aerosol generation, and specifically relates to an aerosol generation product. Background Technology

[0002] With increasing consumer health awareness, the tobacco industry is constantly responding to evolving consumer demands and accelerating the research and development and promotion of new tobacco products. Among these, heated non-combustible aerosol generation technology is widely regarded as a hope and direction for the sustainable development of the tobacco industry. In this technology, the aerosol-generating product is placed in an aerosol-generating device, where it is heated to produce aerosol.

[0003] However, in related technologies, due to the unavoidable loss of aroma during the preparation of the aerosol generating matrix of aerosol generating products, the concentration of aerosol entering the user's mouth when the user inhales the aerosol generating product is relatively low. Utility Model Content

[0004] The purpose of this application is to provide an aerosol generating article that at least solves the problem of low concentration of aerosol entering the user's mouth.

[0005] In a first aspect, embodiments of this application provide an aerosol generating article, the aerosol generating article comprising: a filter section, a functional tube, a smoke-generating section, and a fragrance-carrying substance; the filter section, the functional tube, and the smoke-generating section are arranged sequentially along the axial direction of the aerosol generating article; the functional tube is hollow to form an aerosol channel; at least two fragrance-carrying substances are disposed in the aerosol channel; the fragrance-carrying substances are used to generate aroma-producing substances to mix with the aerosol generated by the smoke-generating section; wherein, along the axial direction of the aerosol generating article, at least one stepped portion is formed on the inner wall of the functional tube, causing the inner diameter of the aerosol channel to change at the stepped portion.

[0006] In some embodiments, along the axial direction of the aerosol-generated article, at least two of the fragrance-carrying substances are located on either side of one of the stepped portions.

[0007] In some embodiments, at least two of the fragrance carriers are located in adjacent segments of one of the stepped portions, and the fragrance carriers are interference-fitted with the inner wall of the functional tube.

[0008] In some embodiments, the functional tube includes a first sub-functional tube and a second sub-functional tube connected together. The first sub-functional tube is close to the filter section, and the second sub-functional tube is far from the filter section. The inner diameter of the first sub-functional tube is larger than the inner diameter of the second sub-functional tube. The step portion is formed at the junction of the inner wall of the first sub-functional tube and the inner wall of the second sub-functional tube. The diameter of the fragrance-carrying substance in the first sub-functional tube is larger than the diameter of the fragrance-carrying substance in the second sub-functional tube.

[0009] In some embodiments, the functional tube includes a third sub-functional tube, a fourth sub-functional tube, and a fifth sub-functional tube sequentially distributed along the aerosol generating article. The inner diameter of the fourth sub-functional tube is smaller than the inner diameter of the third sub-functional tube, and the inner diameter of the fourth sub-functional tube is smaller than the inner diameter of the fifth sub-functional tube. A stepped portion is formed at the junction of the inner wall of the third sub-functional tube and the inner wall of the fourth sub-functional tube, and another stepped portion is formed at the junction of the inner wall of the fourth sub-functional tube and the inner wall of the fifth sub-functional tube. The fragrance-carrying substance is interference-fitted into both the third sub-functional tube and the fifth sub-functional tube.

[0010] In some embodiments, the fragrance-carrying substance is a bursting bead that can rupture upon compression to release the fragrance substance, or rupture upon heating to release the fragrance substance.

[0011] In some embodiments, the aerosol generating article further includes a sealing section connected to the end of the smoke-generating section opposite to the functional tube.

[0012] In some embodiments, the aerosol generating article further includes a fastener segment disposed between the functional tube and the smoke-generating section. The fastener segment is connected to one end of the smoke-generating section near the functional tube. The fastener segment has a through hole along the axial direction of the aerosol channel, and the through hole communicates with the aerosol channel.

[0013] In some embodiments, the aerosol generating article further includes a cavity segment disposed between the firmware segment and the functional tube, and the two ends of the cavity segment are respectively connected to the firmware segment and the functional tube; the cavity segment has a cavity, and the through hole communicates with the aerosol channel through the cavity.

[0014] In some embodiments, the length of the functional tube is 14 mm, and / or the length of the firmware segment ranges from 4 mm to 6 mm, and / or the length of the cavity segment ranges from 2 mm to 4 mm.

[0015] Secondly, embodiments of this application provide an aerosol generation system, the aerosol generation system including an aerosol generation device and an aerosol generation article as described in any one of the first aspects above; the smoke-generating section is located in the aerosol generation device, and the aerosol generation device is used to heat the smoke-generating section.

[0016] In this embodiment, the filter section, functional tube, and smoke-generating section are arranged sequentially along the axial direction of the aerosol-generating product. The functional tube contains an aerosol channel, which contains a fragrance-carrying substance. Therefore, the user can inhale the aerosol-generating product through the filter section, allowing the aerosol generated by the smoke-generating section to enter the filter section through the aerosol channel in the functional tube. The aerosol then enters the user's mouth. As the aerosol flows through the aerosol channel, the fragrance-carrying substance in the aerosol channel can generate aroma-producing substances, which mix with the aerosol in the aerosol channel. This allows the aroma-producing substances to also enter the filter section as aerosols, along with the aerosol generated by the smoke-generating section, increasing the aerosol concentration and improving the taste of the aerosol-generating product. In addition, along the axial direction of the aerosol-generating product, the inner wall of the functional tube has at least one stepped section, causing the inner diameter of the aerosol channel to change at the stepped section. At least two fragrance-carrying substances are provided in the aerosol channel, which is equivalent to at least two fragrance-carrying substances blocking the aerosol channel. Thus, at the location of the fragrance-carrying substances, the flow path of the aerosol-generating airflow generated in the smoke section is narrowed, which has the effect of accelerating the aerosol-generating airflow. After the aerosol-generating airflow passes through the fragrance-carrying substances, the airflow path increases again, which is equivalent to the airflow path changing from large to small and then from small to large. That is, after the aerosol-generating airflow flows out of the smoke section, it first enters the airflow channel. Before the airflow reaches the fragrance-carrying substances, the airflow path is large. When the airflow reaches the fragrance-carrying substances, the airflow path narrows. After the airflow passes through the fragrance-carrying substances, the airflow path increases again, thereby increasing the flow velocity of the aerosol-generating airflow, which is beneficial to increasing the concentration of aerosol flowing into the filter section. That is, in the embodiments of this application, by setting at least one stepped portion on the inner wall of the functional tube along the axial direction of the aerosol generating product, the inner diameter of the aerosol channel changes at the stepped portion. Thus, when the aerosol flows through the aerosol channel, it is equivalent to using the Venturi effect to increase the concentration of aerosol entering the filter section, thereby increasing the concentration of aerosol entering the user's mouth. Furthermore, the aroma-carrying substances in the aerosol generating product can enter the filter section along with the aerosol, effectively improving the taste of the aerosol generating product.

[0028] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0029] like Figures 1 to 7 As shown, the aerosol generating product includes: a filter section 10, a functional tube 20, a smoke-generating section 30, and a fragrance-carrying substance 40.

[0030] The filter section 10, the functional tube 20, and the smoke-generating section 30 are arranged sequentially along the axial direction of the aerosol-generating product. The functional tube 20 is hollow to form an aerosol channel 21. At least two aroma-carrying substances 40 are provided in the aerosol channel 21. The aroma-carrying substances 40 are used to generate aroma-generating substances to mix with the aerosol generated by the smoke-generating section 30. Along the axial direction of the aerosol-generating product, the inner wall of the functional tube 20 has at least one stepped portion, so that the inner diameter of the aerosol channel 21 changes at the stepped portion.

[0031] In this embodiment, the filter section 10, the functional tube 20, and the smoke-generating section 30 are arranged sequentially along the axial direction of the aerosol-generating product. The functional tube 20 is hollow, forming an aerosol channel 21. At least two aroma-carrying substances 40 are provided in the aerosol channel 21. Therefore, the user can inhale the aerosol-generating product through the filter section 10, so that the aerosol generated by the smoke-generating section 30 can enter the filter section 10 through the aerosol channel 21 in the functional tube 20. Then, the aerosol enters the user's mouth. When the aerosol flows through the aerosol channel 21, the aroma-carrying substances 40 in the aerosol channel 21 can generate aroma-producing substances and mix with the aerosol in the aerosol channel 21. This causes the aroma-producing substances to also enter the filter section 10 as aerosols along with the aerosol generated by the smoke-generating section 30, thereby increasing the concentration of aerosols and improving the taste of the aerosol-generating product. Furthermore, along the axial direction of the aerosol-generating product, the inner wall of the functional tube 20 has at least one stepped portion, causing the inner diameter of the aerosol channel 21 to change at the stepped portion. At least two fragrance-carrying substances 40 are disposed in the aerosol channel 21, effectively blocking the aerosol channel 21 with at least two fragrance-carrying substances 40. This effectively narrows the flow path of the aerosol-generating airflow produced by the smoke-generating section 30 at the location of the fragrance-carrying substances 40, thus accelerating the aerosol-generating airflow. The aerosol-generating airflow then passes through the fragrance-carrying substances. As the airflow channel increases, it is equivalent to the airflow channel changing from large to small and then from small to large. That is, after the airflow formed by the aerosol flows out of the smoke-generating section 30, it first enters the airflow channel 21. Before the airflow reaches the fragrance-carrying substance 40, the airflow channel is relatively large. When the airflow reaches the fragrance-carrying substance 40, the airflow channel narrows. After the airflow passes the fragrance-carrying substance 40, the airflow channel increases again, thereby increasing the flow rate of the airflow formed by the aerosol, which is beneficial to increasing the concentration of aerosol flowing into the filter section 10. That is, in this embodiment of the application, by setting at least one stepped portion on the inner wall of the functional tube 20 along the axial direction of the aerosol generating product, the inner diameter of the aerosol channel 21 changes at the stepped portion, thereby increasing the concentration of aerosol entering the filter section 10 when the aerosol flows through the aerosol channel 21, and thus increasing the concentration of aerosol entering the user's mouth. Furthermore, the flavoring substance 40 in the aerosol generating product can enter the filter section 10 along with the aerosol, thereby effectively improving the taste of the aerosol generating product.

[0032] In addition, the filter section 10 mainly serves to transport and filter aerosols, allowing them to enter the user's mouth. The filter section 10 can be filled with filter material, including but not limited to paper filter rods, cotton filter rods, cellulose acetate, and cellulose propionate. The cotton filter rod can be formed from at least one of PP, PA, PET, non-woven fabric, and integral cotton.

[0033] Additionally, in some embodiments, such as Figure 4 and Figure 6 As shown, along the axial direction of the aerosol-generated product, at least two fragrance carriers 40 are located on either side of a stepped section. This arrangement allows the fragrance carriers 40 to be relatively dispersed along the axial direction of the functional tube 20. Thus, before the aerosol-generated airflow reaches another fragrance carrier 40, it passes through at least one stepped section, causing a change in the inner diameter of the airflow channel. This facilitates changes in airflow velocity, which in turn increases the concentration of the aerosol entering the filter section 10.

[0034] Additionally, in some embodiments, such as Figure 4 As shown, at least two fragrance carriers 40 are located in adjacent segments of a stepped section, and the fragrance carriers 40 are press-fitted with the inner wall of the functional tube 20. This arrangement allows the fragrance carriers 40 to be subjected to the force of the inner wall of the functional tube 20, preventing them from easily moving within the tube. In other words, by press-fitting the fragrance carriers 40 with the inner wall of the functional tube 20, the position of the fragrance carriers 40 within the functional tube 20 is ensured to be relatively fixed, thus preventing the fragrance carriers 40 from swaying within the functional tube 20 during the transport of the aerosol-generated product, facilitating the transport of the aerosol-generated product. Furthermore, the fact that at least two fragrance carriers 40 are located in adjacent segments of a stepped section makes them more dispersed, which helps to increase the concentration of the aerosol entering the filter section 10.

[0035] Additionally, in some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, the functional tube 20 includes a first sub-functional tube 211 and a second sub-functional tube 212 connected together. The first sub-functional tube is close to the filter section 10, and the second sub-functional tube 212 is far away from the filter section 10. The inner diameter of the first sub-functional tube 211 is larger than the inner diameter of the second sub-functional tube 212. A stepped portion is formed at the junction of the inner wall of the first sub-functional tube 211 and the inner wall of the second sub-functional tube 212. The diameter of the fragrance-carrying substance 40 in the first sub-functional tube 211 is larger than the diameter of the fragrance-carrying substance 40 in the second sub-functional tube.

[0036] Since the first sub-functional tube 211 and the second sub-functional tube 212 are distributed sequentially along the axial direction of the aerosol-generating product, with the first sub-functional tube 211 closer to the filter section 10 and the second sub-functional tube 212 farther away from the filter section 10, and the inner diameter of the first sub-functional tube 211 being larger than that of the second sub-functional tube 212, when the user draws in the aerosol-generating product through the filter section 10, the aerosol generated by the smoke-generating section 30 can first enter the second sub-functional tube 212, then enter the first sub-functional tube 211, and then enter the filter section 10. Since the inner diameter of the second sub-functional tube 212 is smaller than that of the first sub-functional tube 211, it is equivalent to the aerosol first entering the channel with a smaller inner diameter, which increases the flow rate of the aerosol. Then the aerosol enters the channel with a larger inner diameter, thus the aerosol enters the filter section 10 at a higher speed, thereby increasing the concentration of aerosol entering the filter section 10. Furthermore, both the first sub-functional tube 211 and the second sub-functional tube 212 are provided with fragrance-carrying substances 40. When the aerosol flows through the second sub-functional tube 212 and the first sub-functional tube 211, the fragrance-carrying substances 40 in both the second and first sub-functional tubes increase the amount of aroma-producing substances mixed in the aerosol, thus giving the aerosol-generated product a higher aroma intensity. Additionally, the presence of fragrance-carrying substances 40 in both the first and second sub-functional tubes 211 can, to some extent, delay the aroma decay of the aerosol-generated product and improve its aroma persistence. In addition, the diameter of the fragrance-carrying substance 40 in the first sub-functional tube 211 is larger than the diameter of the fragrance-carrying substance 40 in the second sub-functional tube, so that the fragrance-carrying substance in the first sub-functional tube 211 is interference-fitted with the inner wall of the first sub-functional tube 211, and the fragrance-carrying substance in the second sub-functional tube 212 is interference-fitted with the inner wall of the second sub-functional tube 212, thus preventing the fragrance-carrying substance 40 in the first sub-functional tube 211 from being easy to shake, and the fragrance-carrying substance 40 in the second sub-functional tube 212 from being easy to shake.

[0037] Furthermore, in this embodiment, the number of first sub-functional tubes 211 and the number of second sub-functional tubes 212 can be set according to actual needs. For example, the number of first sub-functional tubes 211 is 1, and the number of second sub-functional tubes 212 is 1; or, for another example, the number of first sub-functional tubes 211 is 2, and the number of second sub-functional tubes 212 is 2. In this case, the two first sub-functional tubes 211 and the two second sub-functional tubes 212 are alternately distributed along the axial direction of the aerosol-generated product. The specific number of first sub-functional tubes 211 and the specific number of second sub-functional tubes 212 are not limited in this embodiment.

[0038] Furthermore, the lengths of the first sub-functional tube 211 and the second sub-functional tube 212 can be set according to actual needs. For example, the length of the first sub-functional tube 211 is 7mm, and the length of the second sub-functional tube 212 is 7mm; or, for another example, the length of the first sub-functional tube 211 is 8mm, and the length of the second sub-functional tube 212 is 6mm. This embodiment of the present application does not limit this. Additionally, the inner diameters of the first sub-functional tube 211 and the second sub-functional tube 212 can be set according to actual needs. For example, the inner diameter of the first sub-functional tube 211 is 3.4mm, and the inner diameter of the second sub-functional tube 212 is 2.85mm; or, for another example, the inner diameter of the first sub-functional tube 211 is 3.5mm, and the inner diameter of the second sub-functional tube 212 is 2.9mm. This embodiment of the present application does not limit this.

[0039] In addition, the outer diameter of the functional tube 20 can be set according to actual needs. For example, the outer diameter of the functional tube 20 is less than or equal to 7.15mm and greater than or equal to 7.1mm.

[0040] Additionally, in some embodiments, such as Figure 6 and Figure 7 As shown, the functional tube 20 includes a third sub-functional tube 213, a fourth sub-functional tube 214, and a fifth sub-functional tube 215 sequentially distributed along the aerosol generating product. The inner diameter of the fourth sub-functional tube 214 is smaller than the inner diameter of the third sub-functional tube 213, and the inner diameter of the fourth sub-functional tube 214 is smaller than the inner diameter of the fifth sub-functional tube 215. A stepped portion is formed at the junction of the inner wall of the third sub-functional tube 213 and the inner wall of the fourth sub-functional tube 214, and another stepped portion is formed at the junction of the inner wall of the fourth sub-functional tube 214 and the inner wall of the fifth sub-functional tube 215. Fragrance-carrying material 40 is interference-fitted into both the third sub-functional tube 213 and the fifth sub-functional tube 215.

[0041] Since the third sub-functional tube 213, the fourth sub-functional tube 214, and the fifth sub-functional tube 215 are sequentially distributed along the axial direction of the aerosol-generating product, and the inner diameter of the fourth sub-functional tube 214 is smaller than that of the third sub-functional tube 213, and the inner diameter of the fourth sub-functional tube 214 is smaller than that of the fifth sub-functional tube 215, the third sub-functional tube 213 can be positioned closer to the filter section 10, while the fifth sub-functional tube 215 can be positioned further away from the filter section 10. Therefore, when the user inhales the aerosol-generating product through the filter section 10, the aerosol generated by the smoke-generating section 30 can first enter the fifth sub-functional tube 215, and then the aerosol enters... The aerosol then enters the third sub-functional tube 213 from the fourth sub-functional tube 214, and then enters the filter section 10. The inner diameter of the fourth sub-functional tube 214 is smaller than that of the third sub-functional tube 213 and smaller than that of the fifth sub-functional tube 215. This is equivalent to the aerosol entering the smaller inner diameter channel, i.e., the fourth sub-functional tube 214, which increases the aerosol flow rate. Then, the aerosol enters the larger inner diameter channel, i.e., the third sub-functional tube 213, so that the aerosol enters the filter section 10 at a higher speed, thereby increasing the concentration of aerosol in the filter section 10. Similarly, when the fifth sub-functional tube 215 is close to the filter section 10 and the third sub-functional tube 213 is far from the filter section 10, it is equivalent to the aerosol entering the smaller inner diameter channel, i.e., the fourth sub-functional tube 214, which increases the flow rate of the aerosol. Then, the aerosol enters the larger inner diameter channel, i.e., the fifth sub-functional tube 215, thus the aerosol enters the filter section 10 at a higher speed, thereby increasing the concentration of aerosol entering the filter section 10. Furthermore, both the third sub-functional tube 213 and the fifth sub-functional tube 215 are provided with fragrance-carrying substances 40. Therefore, when the aerosol flows through the third sub-functional tube 213 and the fifth sub-functional tube 215, the fragrance-carrying substances 40 in both the fifth and third sub-functional tubes can increase the amount of aroma-producing substances mixed in the aerosol, resulting in a higher aroma intensity in the aerosol-generated product. In addition, the fragrance-carrying material 40 is over-insulated in both the third sub-functional tube 213 and the fifth sub-functional tube 215, which can delay the aroma decay of the aerosol-generated product to a certain extent, improve the aroma persistence of the aerosol-generated product, and prevent the fragrance-carrying material 40 in the third sub-functional tube 213 and the fragrance-carrying material 40 in the fifth sub-functional tube 215 from being easily shaken.

[0042] Additionally, in some embodiments, such as Figure 7 As shown, the inner diameter of the third sub-functional tube 213 is equal to the inner diameter of the fifth sub-functional tube 215. With this arrangement, when processing the functional tube 20, it is convenient to process and form the third sub-functional tube 213 and the fifth sub-functional tube 215. That is, the third sub-functional tube 213 and the fifth sub-functional tube 215 can be processed using only the same mold or tools, which can improve the efficiency of processing the functional tube 20.

[0043] Of course, in some embodiments, the inner diameter of the third sub-functional tube 213 may also be smaller than the inner diameter of the fifth sub-functional tube 215. In this case, it is equivalent to the inner diameter of the fourth sub-functional tube 214 being smaller than the inner diameter of the third sub-functional tube 213 and smaller than the inner diameter of the fifth sub-functional tube 215. The inner diameter of the third sub-functional tube 213 is smaller than the inner diameter of the fifth sub-functional tube 215, that is, the inner diameter of the fifth sub-functional tube 215 is the largest, the inner diameter of the third sub-functional tube 213 is the second largest, and the inner diameter of the fourth sub-functional tube 214 is the smallest.

[0044] Furthermore, in this embodiment, the number of third sub-functional tubes 213, fourth sub-functional tubes 214, and fifth sub-functional tubes 215 can be set according to actual needs. For example, the number of third sub-functional tubes 213 can be 1, the number of fourth sub-functional tubes 214 can be 1, and the number of fifth sub-functional tubes 215 can be 1. Alternatively, the number of third sub-functional tubes 213 can be 2, the number of fourth sub-functional tubes 214 can be 2, and the number of fifth sub-functional tubes 215 can be 2. In this case, the two third sub-functional tubes 213, the two fourth sub-functional tubes 214, and the two fifth sub-functional tubes 215 are arranged sequentially along the axial direction of the aerosol-generated product in the order of third sub-functional tube 213, fourth sub-functional tube 214, and fifth sub-functional tube 215. The specific number of third sub-functional tubes 213, fourth sub-functional tubes 214, and fifth sub-functional tubes 215 is not limited in this embodiment.

[0045] Furthermore, the lengths of the third sub-functional tube 213, the fourth sub-functional tube 214, and the fifth sub-functional tube 215 can be set according to actual needs. For example, the length of the third sub-functional tube 213 is 5mm, the length of the fourth sub-functional tube 214 is 4mm, and the length of the fifth sub-functional tube 215 is 5mm; or, for another example, the length of the third sub-functional tube 213 is 5.5mm, the length of the fourth sub-functional tube 214 is 3mm, and the length of the fifth sub-functional tube 215 is 5.5mm. This embodiment of the present application does not limit the specific length of the sub-functional tube 213. Furthermore, the inner diameters of the third sub-functional tube 213, the fourth sub-functional tube 214, and the fifth sub-functional tube 215 can be set according to actual needs. For example, the inner diameter of the third sub-functional tube 213 can be 3.4 mm, the inner diameter of the fourth sub-functional tube 214 can be 2 mm, and the inner diameter of the fifth sub-functional tube 215 can be 3.4 mm; or, for another example, the inner diameter of the third sub-functional tube 213 can be 3.4 mm, the inner diameter of the fourth sub-functional tube 214 can be 2.5 mm, and the inner diameter of the fifth sub-functional tube 215 can be 3.4 mm. This embodiment of the application does not limit the specific dimensions of these dimensions.

[0046] In some embodiments, the flavoring material 40 is a bursting bead that can burst upon compression to release the flavoring substance, or burst upon heating to release the flavoring substance. With this design, when a user uses the aerosol-generated product, applying force to the product causes the flavoring material 40 to burst, thus releasing the flavoring substance. The bursting of the flavoring material 40 also produces a sound, enhancing the enjoyment of the aerosol-generated product. Furthermore, the bursting of the flavoring material 40 upon heating allows the high-temperature aerosol generated by the smoke-generating section 30 to burst and release the flavoring substance once it flows through it, ensuring an effective improvement in the taste of the aerosol-generated product and reducing the need for user compression, thus minimizing user intervention.

[0047] In some embodiments, the aerosol generating article also includes a shell (not shown in the figure); the filter section 10, the functional tube 20, and the smoke-generating section 30 are sequentially disposed inside the shell, and the shell is provided with a compression mark (not shown in the figure), which corresponds to the position of the fragrance-carrying substance 40 along the radial direction of the aerosol generating article. By providing a compression mark on the shell, and the compression mark corresponding to the position of the fragrance-carrying substance 40, when the user uses the aerosol generating article, force can be directly applied to the compression mark, causing the fragrance-carrying substance 40 to break under pressure. That is, the compression mark is equivalent to marking the position of the fragrance-carrying substance 40, ensuring that the user can accurately compress the fragrance-carrying substance 40 to cause it to break.

[0048] It should be noted that the extrusion mark can be a pattern or text printed on the outer casing. Of course, the extrusion mark can also be set on the outer casing as a groove or notch. The specific form of the extrusion mark is not limited in this embodiment.

[0049] In some embodiments, the fragrance carrier 40 includes at least one of fragrance-carrying beads, fragrance-carrying core threads, fragrance-carrying particles, and fragrance-carrying gel beads. Fragrance-carrying beads, fragrance-carrying core threads, fragrance-carrying particles, and fragrance-carrying gel beads are readily available and relatively inexpensive, and can reduce the cost of aerosol-generated products while enriching their fragrance.

[0050] It should be noted that the fragrance-carrying substance 40 may consist only of fragrance-carrying capsules; fragrance-carrying substance 40 may consist only of fragrance-carrying core wire; fragrance-carrying substance 40 may consist only of fragrance-carrying particles; fragrance-carrying substance 40 may consist only of fragrance-carrying gel beads; of course, fragrance-carrying substance 40 may also include fragrance-carrying capsules and fragrance-carrying particles, in which case the fragrance-carrying capsules and fragrance-carrying particles can be mixed; fragrance-carrying substance 40 may also include fragrance-carrying capsules, fragrance-carrying particles, and fragrance-carrying gel beads, in which case the fragrance-carrying capsules, fragrance-carrying particles, and fragrance-carrying gel beads can be mixed. Regardless of whether the fragrance-carrying gel beads are mixed with the fragrance-carrying capsules, or whether the fragrance-carrying capsules, fragrance-carrying gel beads, and fragrance-carrying particles are mixed, it is a physical mixing process, meaning that no chemical reaction occurs between these components.

[0051] Additionally, in some embodiments, such as Figure 1 As shown, the aerosol generating product also includes a sealing section 50, which is connected to the end of the smoke-generating section 30 away from the functional tube 20. By setting the sealing section 50, the sealing section 50 can effectively seal the smoke-generating section 30, preventing the leakage of tobacco particles from the smoke-generating section 30.

[0052] Additionally, in some embodiments, such as Figure 1 As shown, the aerosol generating article also includes a fastener segment 60, which is disposed between the functional tube 20 and the smoke-generating section 30. The fastener segment 60 is connected to the end of the smoke-generating section 30 near the functional tube 20. The fastener segment 60 has a through hole along the axial direction of the aerosol channel 21, and the through hole communicates with the aerosol channel 21. The smoke-generating section 30 contains smoke-generating particles, and the pore size of the through hole is smaller than the particle size of the smoke-generating particles.

[0053] Because the fastener segment 60 has a through hole along the axial direction of the aerosol channel 21, and the through hole communicates with the aerosol channel 21, when the user draws aerosol through the filter segment 10 to generate the product, the aerosol generated by the smoke-generating segment 30 can be transferred to the aerosol channel 21 through the channel, and then the aerosol flows to the filter segment 10. In addition, the diameter of the through hole is smaller than the particle size of the smoke particles, which can prevent the smoke particles from leaking from the smoke-generating segment 30 into the aerosol channel 21, thus avoiding the problem of wasted smoke particles. That is, by setting the fastener segment 60, the smoke-generating segment 30 can be sealed, ensuring that the smoke particles in the smoke-generating segment 30 always remain in the smoke-generating segment 30.

[0054] Additionally, in some embodiments, such as Figure 1As shown, the aerosol generating product also includes a cavity section 70, which is disposed between the fixed section 60 and the functional tube 20, with both ends of the cavity section 70 connected to the fixed section 60 and the functional tube 20 respectively. The cavity section 70 has a cavity, and a through hole communicates with the aerosol channel 21 through the cavity. By setting the cavity section 70, when the user draws the aerosol generating product through the filter section 10, the aerosol generated by the smoke-generating section 30 can flow through the through hole in the fixed section 60 and into the cavity in the cavity section 70, and then the aerosol flows through the cavity into the aerosol channel 21. That is, by setting the cavity section 70, the aerosol from the smoke-generating section 30 can easily enter the aerosol channel 21.

[0055] In addition, in this embodiment, the length of the functional tube 20 is 14 mm, and / or the length of the fastener segment 60 ranges from 4 mm to 6 mm, and / or the length of the cavity segment 70 ranges from 2 mm to 4 mm. This arrangement ensures that the length of the aerosol-generated article is moderate, making it convenient for users to use.

[0056] In addition, when the aerosol generating product includes a filter section 10, a functional tube 20, a cavity section 70, a fastener section 60, a smoke generating section 30, and a sealing section 50, if the length of the aerosol generating product is 45mm, then the length of the filter section 10 can be 6mm, the length of the functional tube 20 can be 14mm, the length of the cavity section 70 can be 2mm, the length of the fastener section 60 can be 6mm, the length of the smoke generating section 30 can be 12mm, and the length of the sealing section 50 can be 5mm.

[0057] This application provides an aerosol generation system, which includes an aerosol generation device and an aerosol generation product from any of the above embodiments; a smoke-generating section 30 is located in the aerosol generation device, which is used to heat the smoke-generating section 30.

[0058] The aerosol generating device includes a device body and a heating component. The device body has a receiving space, and the heating component is located in the receiving space. The smoke generating section 30 can be placed in the receiving space and heated by the heating component.
