Description

Technical Field

[0001] This invention relates to the field of novel tobacco technology, and in particular to an aerosol generation product and system suitable for surrounding heating. Background Technology

[0002] The atomizing agents added to new tobacco products such as e-cigarettes and heated tobacco products have three main functions: First, they form a large amount of aerosol when heated, producing smoke that visually simulates the burning effect of traditional tobacco; second, they stimulate the throat to produce a throat hit, bringing the physiological experience and satisfaction of smoking traditional tobacco, thereby achieving a smoking alternative; and third, as an excellent solvent, they can hold nicotine, nicotine salts, and various flavor substances, ensuring the effective release of core components when heated.

[0003] Atomizing agents play an important role in new tobacco products, but they also have problems such as strong hygroscopicity and easy loss upon contact with air, which leads to a decline in the quality of tobacco products and results in insufficient smoke volume and poor taste in the first two puffs. Summary of the Invention

[0012] Preferably, a flavoring agent is also added to the condensation buffer medium and / or atomizing agent carrier; The flavoring agent is at least one of the following: plant essential oil, plant absolute oil, plant monomers (such as menthol, steviol glycosides, etc.), and synthetic fragrance raw materials (such as WS-3, dihydroactinol, lactic acid, neotame, etc.).

[0013] An aerosol generation system, comprising: Aerosol-generating products as described in any of the above items; An aerosol generating device is provided, wherein the aerosol generating device is provided with a heating chamber surrounding the aerosol generating product, and the heating chamber covers the first condensation buffer section, the atomizing material supply section and the second condensation buffer section.

[0014] Preferably, the heating chamber is provided with a single-section heating element, the length of which is less than or equal to the sum of the lengths of the first condensation buffer section, the atomized material supply section, and the second condensation buffer section, and greater than the sum of the lengths of the first condensation buffer section and the atomized material supply section; or, The heating chamber is provided with multiple heating elements.

[0015] To address the problems existing in the prior art, this application provides an aerosol generating article suitable for surrounding heating, comprising a filter section, a first condensation buffer section, an atomizing substance supply section, and a second condensation buffer section connected in sequence; the outer periphery of the first condensation buffer section, the atomizing substance supply section, and the second condensation buffer section is wrapped with a metal foil layer; the atomizing substance supply section includes a porous atomizing agent carrier and an atomizing agent loaded on the atomizing agent carrier; the first condensation buffer section and the second condensation buffer section contain a condensation buffer medium with a high surface area.

Furthermore, in existing tobacco products, the generation of high-temperature aerosols and their condensation buffers occur in the same segment and medium. However, this application separates the atomizing agent supply segment and the high-temperature aerosol condensation buffer segment, setting the atomization aerosol production system and the condensation buffer system independently. This ensures sufficient atomization volume and allows the aerosol to be condensed and re-evaporated under high-temperature conditions through the condensation buffer media in the first and second condensation buffer segments, providing a smoking experience different from existing tobacco products.

[0019] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly set on the other component; when a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to the other component.

[0021] It should be noted that the structures, proportions, sizes, etc., shown in the accompanying drawings of this specification are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the conditions under which this application can be implemented. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportions, or adjustments to the size should still fall within the scope of the technical content disclosed in this application, provided that they do not affect the effects and purposes that this application can produce.

[0022] This invention provides an aerosol generation product suitable for surrounding heating, comprising a filter section 1, a first condensation buffer section 2, an atomizing material supply section 3, and a second condensation buffer section 4 connected in sequence; The outer periphery of the first condensation buffer section 2, the atomizing material supply section 3, and the second condensation buffer section 4 is wrapped with a metal foil paper layer 5; The atomizing material supply section 3 includes a porous atomizing agent carrier and an atomizing agent loaded on the atomizing agent carrier; The first condensation buffer section 2 and the second condensation buffer section 4 are provided with condensation buffer media, which have a high surface area.

[0023] In liquid e-cigarettes, the atomizing agent is stored in liquid form, making it easier to atomize when heated, thus providing a larger atomization volume. However, liquid e-cigarettes are only suitable for individual use and lack social and sharing attributes. In solid tobacco products, adding the atomizing agent during the preparation of reconstituted tobacco sheets presents challenges due to complex manufacturing processes, the need for specialized equipment, and high costs. Furthermore, the baking and drying process required for reconstituted tobacco sheets makes adding volatile flavorings difficult and limits the amount that can be added. Spraying the atomizing agent onto the surface of tobacco or other carriers creates processing difficulties due to the sticky atomizing agent. Additionally, the moisture absorption of the tobacco or finished cigarette by the atomizing agent affects heating efficiency, leading to insufficient smoke volume and poor taste.

[0024] To address the problems existing in the prior art, this application provides an aerosol generation product suitable for surrounding heating, comprising a filter section 1, a first condensation buffer section 2, an atomizing substance supply section 3, and a second condensation buffer section 4 connected in sequence; the outer periphery of the first condensation buffer section 2, the atomizing substance supply section 3, and the second condensation buffer section 4 is wrapped with a metal foil paper layer 5; the atomizing substance supply section 3 includes a porous atomizing agent carrier and an atomizing agent loaded on the atomizing agent carrier; the first condensation buffer section 2 and the second condensation buffer section 4 are provided with a condensation buffer medium, which has a high surface area. The aerosol generating product suitable for surrounding heating provided in this application has a first condensation buffer section 2 and a second condensation buffer section 4 respectively set at both ends of the atomizing material supply section 3. The first condensation buffer section 2 and the second condensation buffer section 4 do not contain atomizing agent themselves, and the outer circumference of the three sections is wrapped by a metal foil layer 5, so that the atomizing agent is surrounded by other materials in both the circumferential and peripheral directions, and is not directly exposed to the air, which can effectively avoid the problem of cigarette moisture absorption, and generate sufficient and stable atomized aerosol during use, ensuring a good smoking experience. In addition, the generation of high-temperature aerosol in existing tobacco products and its condensation buffer occur in the same section and in the same medium. However, this application sets the atomizing agent supply section 3 and the high-temperature aerosol condensation buffer section separately, setting the atomization aerosol production system and the condensation buffer system independently. This ensures sufficient atomization volume, and the aerosol is condensed and re-evaporated under high temperature conditions by the condensation buffer medium in the first condensation buffer section 2 and the second condensation buffer section 4, providing a smoking experience different from existing tobacco products.

[0025] The aerosol generating product suitable for surrounding heating provided in this application has a large amount of smoke, is easy to share, and provides consumers with a good smoking experience by condensing and re-evaporating the aerosol under high temperature conditions through a condensation buffer medium.

[0026] In this application, the outer periphery of the first condensation buffer section 2, the atomizing substance supply section 3, and the second condensation buffer section 4 are all wrapped with a metal foil paper layer 5. During the heating process, they absorb heat and their temperature rises. Then, outside air enters the second condensation buffer section 4 from the distal lip end and is heated in the high-temperature condensation buffer medium. The hot air then enters the atomizing substance supply section 3, mixes and flows with the atomizing agent released after the atomizing agent carrier is heated, and then enters the first condensation buffer section 2. Here, the high-temperature condensation buffer medium condenses and buffers the air, and then blows it out with the user's suction and into the user's mouth.

[0027] The first condensation buffer section 2 and the second condensation buffer section 4 of this application contain condensation buffer media that do not contain atomizing agents. These media can fully interact with the aerosol, causing it to condense and be buffered within them, and then released back into the user's mouth during the purging process. In contrast, the condensation sections of existing conventional cigarettes only condense without releasing the aerosol, resulting in a significant difference in working principle and effect. Furthermore, both condensation buffer sections of this application are heated during use, allowing the condensation buffer media to interact with the air or aerosol at a high temperature. In contrast, the condensation sections of existing conventional cigarettes are not heated and remain at a low temperature, leading to a significant difference in aerosol component adsorption due to temperature variations.

[0028] In conventional cigarettes, aerosol generation and buffering both occur in the tobacco segment. This segment must both carry the atomizing agent, generate aerosol upon heating, and buffer the aerosol, thus limiting both aerosol generation and load. Consequently, the amount of aerosol produced is limited, impacting the vaping experience. This application, however, by incorporating a first condensation buffer segment 2 and a second condensation buffer segment 4, allows a significant amount of aerosol generated in the atomizing material supply segment 3 to be buffered in portions of the first and second condensation buffer segments 2 and 4. During the intervals between puffs, a large amount of aerosol can be buffered throughout the aerosol-generating product, ensuring the user ingests sufficient and abundant aerosol with each puff, significantly improving the vaping experience.

[0029] In this application, the metal foil-containing paper layer 5 surrounding the first condensation buffer section 2, the atomizing substance supply section 3, and the second condensation buffer section 4 can be cigarette paper coated with a metal layer or composite paper containing metal foil; the metal can be aluminum (i.e., aluminized cigarette paper or aluminum foil composite paper) or other metals in the art. The metal foil-containing paper layer 5 not only plays a role in transferring heat during the heating process, but also blocks external influences and plays a role in moisture insulation, ensuring the quality stability of the aerosol-generated product during transportation and storage.

[0066] Comparative Example 2 BAT Neo Original Flavor Surround Heated Cigarette Cartridge, named Comparison Cigarette 2 Comparative Example 3 The baisha 21mm circumference surround-heated tobacco cartridge sold by Hunan China Tobacco Industry Co., Ltd. is named Comparison Cigarette 3.

[0067] Experiment 1 Examples 1-3 and Comparative Examples 1-3 were tested using the following testing instruments and apparatus: Smoking accessories: USONIC two-stage surround heating appliance manufactured by Hunan Tobacco Industry Co., Ltd. Fruit flavorings (watermelon flavoring, orange flavoring, strawberry flavoring): Produced by the Technology Center of Hunan Tobacco Industry Co., Ltd.

[0068] Detector: Shenzhen Feihong Technology Co., Ltd. HF-Y1211 heated cigarette smoke transmittance detector; it has three smoke concentration levels: high concentration, medium concentration, and low concentration, with different concentration ranges for each mode. The concentration range is 0%-100% for all three smoke concentrations. Smoking parameters: 8 puffs per cigarette, 2 seconds per puff, 30-second interval, 55ml puff volume per interval. Test results are shown in Table 1.

[0070] As shown in Table 1, the three-stage heated non-combustible cigarette of this invention produces a larger amount of smoke than the comparative cigarettes 1, 2, and 3 in the comparative examples. The two-stage aerosol-produced product produces the smallest amount of smoke, indicating that it only has an atomization stage to generate aerosols, without a condensation and buffering stage. Furthermore, the atomizing agent load in the atomization stage is saturated, and the atomized vapor cannot be buffered again in the atomization stage, resulting in a very small amount of smoke in the aerosol-produced product. Moreover, although filter stage 1 includes a condensation and cooling stage, the condensation and cooling stage often uses an empty tube and is not heated, making it difficult to buffer a large amount of atomized vapor. The amount of atomized vapor carried out by the hot airflow is limited. Therefore, the smoke concentration of comparative cigarette 1 is still low.

[0071] Experiment 2 Four cigarettes each from the experimental cigarettes (1-3) and the control cigarette (3) were inserted into matching smoking devices for smoking. According to the national standard "Sensory Technical Requirements" (GB5606.4 2005), multiple sensory evaluators conducted sensory evaluations of the cigarettes, primarily examining the aroma value and quantity of the tobacco aroma. These indicators were scored from 0 to 10, with higher scores indicating a better sensory experience during smoking. The comparative evaluations of the four different cigarette samples are shown in Table 2. Table 1 Comparative evaluation results of different cigarette samples in surround-heated smoking devices

[0072] Experiment 3 One experimental cigarette (2) and one control cigarette (3) were taken. Under conditions of RH 60%±2, temperature 25℃±0.5, and analytical balance accuracy 0.01, the weight of the cigarette was measured every minute. A moisture absorption curve for the cigarette under these conditions was plotted. The results are shown below. Figure 2 The results showed that the experimental cigarette 2 hardly absorbed moisture when the ambient temperature and humidity reached 60%.

[0073] The above description is merely an embodiment of the present invention. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of the present invention, but these improvements all fall within the protection scope of the present invention.
