Description

Technical Field

[0001] The utility model provides a novel hierarchical structure for the core section of a heated cigarette, aiming to improve the efficiency of central heating and peripheral heating cigarettes while reducing tobacco consumption. By adopting a hierarchical filling method inside the cigarette core, for central heating cigarettes, the outer layer is filled with a slow-release material to optimize the heating performance; for peripheral heating cigarettes, the slow-release material is filled in the inner core to improve the heating uniformity. This design aims to provide consumers with a more satisfactory smoking experience and play a positive role in environmental protection and resource conservation. Background Art

[0002] Currently, there are two heating methods for heated cigarettes: central heating and peripheral heating. For central heating, the outermost layer of tobacco leaves often cannot be fully utilized because it does not directly contact the heat source. Similarly, when using peripheral heating, the innermost layer of tobacco often cannot be fully utilized. This is because the peripheral heating method causes the outer layer of the cigarette to be heated more, while the temperature of the inner layer is relatively low, resulting in the incomplete release of the components of the inner layer of tobacco. This situation affects the quality of the cigarette and the smoking experience. The unutilized tobacco leaves mean that the key components of the tobacco may not be fully volatilized, resulting in smokers not being able to obtain a complete taste experience. To solve this problem, a novel design for the core section is needed that can fully utilize the tobacco leaves in each layer of the core section to ensure that the components in all parts can be effectively released. Summary of the Utility Model

[0003] In view of the above problems, the purpose of the present utility model is to provide, for central heating, a structure in which the inner part is filled with tobacco leaves and the outer layer is filled with a non-smoking or slightly smoking material to enhance heat conduction and improve heating efficiency; for peripheral heating, a structure in which the outer layer is filled with tobacco leaves and the inner part is filled with a non-smoking or slightly smoking material to improve heating uniformity and reduce tobacco consumption. This technology can not only improve the utilization rate of tobacco resources, but also improve the taste and quality of cigarettes, enhance the stability of the release of smoke gas in each puff, and provide consumers with a more satisfactory smoking experience.

[0004] To achieve the above objectives, the present utility model adopts the following technical solutions:

[0005] A hierarchical structure for the core section of a heated cigarette, comprising a rod core and an outer layer wrapped around the outer periphery of the rod core, and the structure is in the following two forms:

[0006] (1) The rod core is a rod core filled with tobacco leaves, the outer layer wrapped around the outer periphery of the rod core is a slow-release material outer layer, and the cross-sectional area ratio of the rod core to the slow-release material outer layer is 1:1. The slow-release material outer layer is a non-smoking or slightly smoking material outer layer;

[0007] (2) The rod core is made of a slow-release material. The outer layer wrapped around the rod core is a tobacco leaf outer layer, and the cross-sectional area ratio of the rod core to the tobacco leaf outer layer is 1:2. The rod core made of the slow-release material is a non-smoking or less-smoking material rod core.

[0008] The slow-release material is a non-smoking or less-smoking material, which can be acetate fiber, paper, tobacco sheet or polylactic acid material, and can also be added with spices.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows: It can make full use of the tobacco leaves in each layer of the tobacco core section to ensure that the components in all parts can be effectively released. This technology can not only improve the utilization rate of tobacco resources, but also improve the taste and quality of cigarettes, improve the stability of the gradual release of cigarette smoke, and provide a more satisfactory smoking experience for smokers. The filled slow-release material can not only achieve the slow-release effect and the stability of the gradual release, but also control the release mode of key components, thereby improving the safety and controllability of the product. The key components (propylene glycol, nicotine, glycerol, etc.) in the tobacco core show an exponential decline, especially in the first two puffs, with a large release amount. Some key components such as propylene glycol, nicotine and glycerol are first transferred to the slow-release material and gradually released during the smoking process, thus achieving the slow-release effect.

Embodiment

[0014] Such as Figure 1As shown in the figure, Embodiment 1 of the present utility model discloses a cigarette core segment structure for internal central heating, which includes a tobacco rod core a and a slow-release material outer layer b. The slow-release material outer layer b is made of paper material and wraps the tobacco rod core a layer by layer. A mint-flavored spice is added to the slow-release material outer layer b. In Embodiment 1, the cross-sectional area ratio of the inner and outer layers is 1:1, saving 1 / 2 of the tobacco amount compared with before. In Embodiment 1, the total length of the cigarette core segment is 12 mm. In Embodiment 1, the cross-sectional area ratio of the inner and outer layers is 1:1, saving half of the tobacco amount compared with the traditional structure. This saving is an important cost advantage for tobacco manufacturers and is also beneficial to improving production efficiency and resource utilization rate. A mint-flavored spice is added in Embodiment 1. This improvement can bring a fresher taste and unique fragrance to the cigarette, enhancing the quality of the smoking experience. Through taste evaluation and quality testing, it can be verified that Embodiment 1 has a significant improvement in taste and quality compared with the traditional cigarette core structure. Embodiment

[0015] As Figure 2 shown in the figure, Embodiment 2 of the present utility model discloses a cigarette core segment structure for external circumferential heating, which includes a tobacco outer layer 1 and a slow-release material rod core 2. The slow-release material rod core 2 is made of acetate fiber tow material, and a lemon-flavored spice is added to the material rod core 2. In Embodiment 2, the cross-sectional area ratio of the inner and outer layers is 1:2. In Embodiment 2, the total length of the cigarette core segment is 12 mm. Compared with the traditional cigarette core structure, the cross-sectional area ratio of the inner and outer layers in Embodiment 2 is 1:2, which means that the required amount of tobacco is relatively small.

[0016] Compared with before, Embodiment 2 saves 1 / 3 of the tobacco amount. This saving can not only reduce the raw material cost for tobacco manufacturers but also help improve production efficiency. Embodiment 2 adopts the design of external circumferential heating, which can conduct and distribute heat more effectively compared with the traditional structure. Through comparative tests, it can be observed that the heating performance of Embodiment 2 is more uniform and stable, which helps improve the combustion efficiency of the cigarette and reduce the waste caused by uneven combustion. Improve the taste and quality of the cigarette: A lemon-flavored spice is added in Embodiment 2. This improvement can not only enhance the taste of the cigarette but also bring a fresher smoking experience to smokers. Through consumer feedback and taste testing, it can be verified that Embodiment 2 has a significant improvement in taste and quality compared with the traditional cigarette core structure. The total length of the cigarette core segment in Embodiment 2 is 12 mm. This length has been carefully designed and tested to ensure sufficient combustion of the tobacco during the smoking process without affecting the persistence of the tobacco and the smoking time.
