Description

Technical Field

[0001] This utility model relates to the field of heated cigarette technology, and more specifically, to a heated cigarette aroma-carrying structure with a composite filter rod. Background Technology

[0002] In traditional heated cigarettes, flavorings are typically applied to the filler section, and then released by heating with a device. While this method can satisfy consumers' flavor preferences to some extent, the lack of precise control over the temperature field of the filler in current heating devices leads to inconsistent flavor release. This inconsistency not only affects the pleasure of smoking but can also sometimes produce unpleasant odors, resulting in an unstable smoking experience. Furthermore, flavorings may decompose at high temperatures, producing unpleasant smells and further impacting the consumer's smoking experience.

[0003] In conclusion, how to achieve a continuous and stable release of aroma in cigarettes while improving filtration efficiency and sensory experience is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a heated cigarette aroma-carrying structure with a composite filter rod, which can achieve a continuous and stable release of cigarette aroma, while improving the filtration efficiency and sensory experience of the cigarette.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A heated cigarette aroma-carrying structure with a composite filter rod, comprising:

[0007] Inlet end fiber bundle filter rod;

[0008] A positioning fiber bundle filter rod is provided with a fragrance-carrying cavity between one end of the positioning fiber bundle filter rod and the end of the inlet end fiber bundle filter rod;

[0009] A fragrance-carrying thread is disposed within the fragrance-carrying cavity;

[0010] A tipping paper, which wraps around the outer periphery of the fragrance-carrying cavity;

[0011] A smoke-generating carrier is located at the other end of the positioning fiber bundle filter rod.

[0012] In one embodiment, the tipping paper has micropores in the region of the inlet end fiber bundle filter rod.

[0013] In one embodiment, the splicing paper is uniformly provided with at least two micropores along the circumferential direction.

[0014] In one embodiment, the density of the micropores is 10 pores / cm².2 -15 holes / cm 2 The pore size of the micropores is 0.2mm-0.4mm.

[0015] In one embodiment, the fragrance-carrying thread comprises a fibrous element or a biodegradable polymer.

[0016] In one embodiment, the incense-carrying thread is formed by orderly winding a thin thread-like material in one direction, or the incense-carrying thread is formed by randomly winding a thin thread-like material in different directions.

[0017] In one embodiment, the fiber density of the positioning fiber filter rod is 25 mg / cm³. 3 -30mg / cm 3 .

[0018] In one embodiment, the smoke-generating carrier is attached to the end of the positioning fiber filter rod.

[0019] In one embodiment, the axial length of the inlet end fiber bundle filter rod is 5mm-9mm, and the axial length of the positioning fiber bundle filter rod is 8mm-10mm.

[0020] In one embodiment, the axial length of the fragrance-carrying cavity is 13mm-17mm, and the axial length of the smoke-generating carrier is 12mm-14mm.

[0021] When using the heated cigarette aroma-carrying structure with composite filter rod provided by this utility model, when preparation is required, the smoke-generating carrier can be placed in the heated cigarette device. After preheating, the aerosol passes through the positioning wire bundle filter rod, which cools and traps particulate matter. Then, the aerosol enters the aroma-carrying cavity containing the aroma-carrying wire. The aroma substances in the aroma-carrying wire are slowly and stably released under the action of low temperature, and finally enter the user's mouth through the inlet end wire bundle filter rod, achieving the effect of enhancing aroma and flavor.

[0022] In other words, by igniting the smoke-generating carrier to produce a hot airflow, this hot airflow continuously and stably heats the fragrance-carrying wire, allowing for continuous distillation and providing consumers with a consistently pleasant experience. The advantage of this method is that it not only reduces unpleasant odors caused by improper temperature control but also significantly enhances the consumer's sensory experience. Furthermore, since the fragrance-carrying material and aroma-producing substances in the fragrance-carrying wire do not directly participate in the heating process, it effectively avoids the decomposition of the fragrance-carrying wire due to high temperatures, thus maintaining the purity and stability of the fragrance. This ternary composite filter rod structure, integrating filtration, cooling, and fragrance-carrying functions, indirectly heats the fragrance-carrying material through the hot airflow of flue gas, effectively filtering harmful substances in the flue gas and ensuring the uniform release of the fragrance.

[0023] In summary, the heated cigarette aroma-carrying structure with composite filter rod provided by this utility model can achieve continuous and stable release of cigarette aroma, while improving the filtration efficiency and sensory experience of cigarettes. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] The core of this invention is to provide a heated cigarette aroma-carrying structure with a composite filter rod, which can achieve a continuous and stable release of cigarette aroma while improving the filtration efficiency and sensory experience of the cigarette.

[0033] Please refer to Figure 1 This specific embodiment provides a heated cigarette aroma-carrying structure with a composite filter rod, comprising:

[0034] Inlet end fiber bundle filter rod 1;

[0035] The positioning fiber bundle filter rod 5 has a fragrance-carrying cavity between one end and the end of the inlet fiber bundle filter rod 1;

[0036] Incense-carrying thread 3 is located inside the incense-carrying cavity;

[0037] The receiving paper 4 wraps around the outer periphery of the fragrance-carrying cavity;

[0038] The smoke-generating carrier 6 is located at the other end of the positioning fiber bundle filter rod 5.

[0039] It should be noted that, in the preparation of the impregnation solution, this application can use a combination of fragrance module and moisturizing solvent. After thorough dissolution, the fragrance (i.e., fragrance carrier 3) is prepared for use to ensure uniform distribution and stability. The production process of the fragrance carrier 3 includes multiple steps such as material preparation, static electricity removal, impregnation, extrusion homogenization, drying, and rewinding. Each step is carefully designed and strictly controlled to ensure the quality of the final product. This device sets a fragrance-carrying cavity between the end of the positioning fiber filter rod 5 and the end of the inlet fiber filter rod 1, and places the fragrance carrier 3 within the cavity. The fragrance carrier 3 is then continuously and stably heated by a hot flue gas flow, allowing the aroma-producing substances in the fragrance carrier 3 to be continuously distilled, providing consumers with a consistently pleasant experience and reducing unpleasant odors caused by other factors that could negatively impact their senses.

[0040] It should also be noted that existing heating devices often struggle to precisely control the temperature field of the smoke core, resulting in poor consistency and potentially unpleasant aromas and an unstable vaping experience. To avoid these issues, this device uses a hot airflow to continuously and stably heat the fragrance-carrying material (i.e., fragrance-carrying thread 3), allowing the aroma-producing substances to continuously distill and providing consumers with a consistently pleasant experience. Specifically, the fragrance-carrying material and aroma-producing substances in fragrance-carrying thread 3 do not directly participate in the heating process. Furthermore, the hot airflow can continuously heat the fragrance-carrying material at a low temperature of 120±10℃, ensuring a uniform and stable release of the aroma-producing substances. Moreover, the fragrance in fragrance-carrying thread 3 is encapsulated by the smoke-generating agent, so it is not lost when the user is not vaping.

[0041] In practical applications, the dimensions and assembly methods of the inlet end fiber bundle filter rod 1, positioning fiber bundle filter rod 5, fragrance carrier 3, tipping paper 4, and smoke-generating carrier 6 can be determined according to the actual situation and needs.

[0042] When using the heated cigarette aroma-carrying structure with composite filter rod provided by this utility model, when preparation is required, the smoke-generating carrier 6 can be placed in the heated cigarette device. After preheating, the aerosol passes through the positioning wire bundle filter rod 5. The positioning wire bundle filter rod 5 cools down and traps particulate matter. Then, the aerosol enters the aroma-carrying cavity containing the aroma-carrying thread 3. The aroma substances in the aroma-carrying thread 3 are slowly and stably released under the action of low temperature, and finally enter the user's mouth through the inlet end wire bundle filter rod 1, achieving the effect of enhancing the aroma.

[0043] In other words, by igniting the smoke-generating carrier 6, a hot airflow is generated, which continuously and stably heats the fragrance-carrying wire 3, allowing it to continuously distill and providing consumers with a consistently pleasant experience. The advantage of this method is that it not only reduces unpleasant odors caused by improper temperature control but also significantly enhances the consumer's sensory experience. Furthermore, since the fragrance-carrying material and aroma-producing substances in the fragrance-carrying wire 3 do not directly participate in the heating process, it effectively avoids the decomposition of the fragrance-carrying wire 3 due to high temperatures, thus maintaining the purity and stability of the fragrance. This ternary composite filter rod structure, integrating filtration, cooling, and fragrance-carrying functions, indirectly heats the fragrance-carrying material through the hot airflow of flue gas, effectively filtering harmful substances in the flue gas and ensuring the uniform release of the fragrance.

[0044] In summary, the heated cigarette aroma-carrying structure with composite filter rod provided by this utility model can achieve continuous and stable release of cigarette aroma, while improving the filtration efficiency and sensory experience of cigarettes.

[0045] In one embodiment, the tipping paper 4 has micropores 2 in the region of the inlet end fiber bundle filter rod 1.

[0046] It should be noted that the tipping paper 4 wraps around the outer periphery of the aroma-carrying cavity to bond the filter rod to the smoke-generating carrier 6 (i.e., tobacco segments), forming a complete cigarette structure. Part of the tipping paper 4 is designed with micropores 2, which can adjust the amount of air inhaled, affecting the smoke concentration and taste. Furthermore, the micropores 2 can be created using laser perforation technology.

[0047] In one embodiment, the splicing paper 4 is provided with at least two micropores 2 uniformly along the circumference.

[0048] In one embodiment, the density of micropores 2 is 10 pores / cm². 2 -15 holes / cm 2 The pore size of micropore 2 is 0.2mm-0.4mm. In practical applications, the density and pore size of micropore 2 can be adjusted according to actual conditions and requirements.

[0049] In one embodiment, the fragrance-carrying thread 3 comprises fibrous components or a biodegradable polymer. For example, the fragrance-carrying thread 3 can be made from fibrous components (such as cellulose substrates), which are soaked in a distillation solution (fragrance module + moisturizing solvent) and then dried. The mass ratio of the fragrance module to the moisturizing solvent in the distillation solution can be 1:2 to 1:4.

[0050] In one embodiment, the fragrance-carrying thread 3 is formed by orderly winding a thin thread-like material into a ball in a certain direction, such as... Figure 2 Example 1 and Figure 3 The illustrated second embodiment shows examples where the incense-carrying thread 3 is formed by an orderly coil of a single thin thread-like material in one direction. Alternatively, the incense-carrying thread 3 may be formed by a random coil of a single thin thread-like material in different directions, such as... Figure 4 Example 3 is shown.

[0051] The cigarettes produced by this device (Examples 1 to 3) were compared with ordinary cigarettes (a control group without fragrance thread 3). Multiple judges evaluated the cigarettes by smoking them according to the enterprise standard "Sensory Quality Evaluation Standard for Heated Tobacco Products". The cigarette heating device is a centrally electrically heated heated tobacco product, heating the cigarette cartridge within the range of 300℃ to 350℃. The evaluation was conducted according to the nine-point evaluation standard of "Technical Requirements for Sensory Quality Evaluation of Heated Tobacco Products". The evaluation indicators and scoring criteria are shown in Table 1.

[0052] Table 1 Summary of Sensory Quality Records of Heated Cigarettes

[0053]

[0054] As shown in Table 1, the tobacco cartridge of Example 1 produces rich smoke, a full-bodied aroma, moderate strength, and a harmonious finish with a sweet aftertaste. Examples 2 and 3 also produce rich smoke, a full and delicate aroma, moderate strength, and a harmonious finish with a sweet and refreshing aftertaste. The aroma consistency before and after 11 puffs is better than that of the tobacco cartridge of Example 1. In contrast, the tobacco cartridge of the control group produces less smoke, a weak aroma, and while the first 6 puffs are comfortable, the aftertaste is unpleasant after the last 5 puffs. The aroma consistency of the control group is poor. Therefore, the tobacco cartridge scores of Examples 1 to 3 of this application are all higher than those of the control group, further demonstrating that by igniting the smoke-generating carrier 6 to generate a hot airflow, which continuously and stably heats the aroma-carrying wire 3, continuous distillation of the aroma-carrying wire 3 can be achieved, thus providing consumers with a consistently pleasant experience.

[0055] In one embodiment, the fiber density of the positioning fiber filter rod 5 is 25 mg / cm³. 3 -30mg / cm 3 During application, the fiber density of the positioning fiber filter rod 5 can be selected according to the actual situation and needs.

[0056] In one embodiment, the smoke-generating carrier 6 is attached to the end of the positioning fiber bundle filter rod 5. Of course, in actual application, other connection methods can be used to connect the smoke-generating carrier 6 and the positioning fiber bundle filter rod 5 according to the actual situation and needs.

[0057] In one embodiment, the axial length of the inlet end fiber bundle filter rod 1 is 5mm-9mm, and the axial length of the positioning fiber bundle filter rod 5 is 8mm-10mm. For example, the axial length of the inlet end fiber bundle filter rod 1 can be set to 7mm, and the axial length of the positioning fiber bundle filter rod 5 can be set to 10mm.

[0058] In one embodiment, the axial length of the fragrance-carrying cavity is 13mm-17mm, and the axial length of the smoke-generating carrier 6 is 12mm-14mm. For example, the axial length of the fragrance-carrying cavity can be set to 15mm, and the axial length of the smoke-generating carrier 6 can be set to 13mm.

[0059] This application discloses a heated cigarette flavoring structure with a composite filter rod. By continuously and stably heating the flavoring material (flavoring line 3) with hot airflow, the flavoring substances can be continuously distilled, providing consumers with a consistently pleasant experience. The advantage of this method is that it not only reduces unpleasant odors caused by improper temperature control but also significantly enhances the consumer's sensory experience. Furthermore, since the flavoring material and flavoring substances in the flavoring line 3 do not directly participate in the heating process, it effectively avoids the decomposition of the flavoring due to high temperatures, thus maintaining the purity and stability of the flavoring. In other words, this device not only effectively filters harmful substances in the smoke but also ensures the uniform release of the flavoring.

[0060] Through these innovative flavor-carrying technologies (i.e., by using hot airflow to continuously and stably heat the flavor-carrying wire 3, enabling continuous distillation of aroma-producing substances), heated cigarettes not only provide a more pleasant and stable smoking experience but also reduce potential health risks to consumers. The application of this technology will undoubtedly bring about a new revolution in the heated cigarette market, offering consumers a healthier and more enjoyable smoking option. With people's dual pursuit of health and a pleasurable experience, the technology of using hot airflow to continuously and stably heat the flavor-carrying wire 3, as described in this application, will undoubtedly lead the development direction of the heated cigarette industry, providing consumers with a completely new way of smoking. Specifically, the flavor-carrying material and aroma-producing substances do not participate in the heating process; the hot airflow can continuously heat the flavor-carrying wire 3 at a low temperature. The aroma-producing substances in the flavor-carrying wire 3 are uniformly and stably released under the protection of the smoke-generating agent. Moreover, the aroma-producing substances in the flavor-carrying wire 3 are not lost when the user does not smoke it.
