Description

Technical Field

[0001] This patent belongs to the field of heated smoking device technology, specifically relating to an aerosol generation system that reduces the smell of toasted paper. Background Technology

[0002] In the field of new tobacco products, external heating technology holds an indispensable position in the international market due to its advantages such as simple structure, ease of cleaning, and good cigarette compatibility. However, existing external heating products generally suffer from the following problems: 1. When the external heating device heats the tobacco, the heat is from the outside to the inside of the tobacco. Therefore, it is inevitable that the cigarette paper will be baked and produce unpleasant smells such as the smell of the baked paper. Since the smoke and the smell of the baked paper share the same air path, the impurities will mix into the mainstream smoke and affect the sensory experience. 2. During the cigarette heating process, the cigarette paper and adjacent sections of tobacco are easily baked by high temperature, releasing unpleasant odors such as "baked paper smell".

[0003] Therefore, it is necessary to improve the structure of existing peripheral heating appliances to reduce the paper-burning smell when smoking cigarettes. Summary of the Invention

[0004] The purpose of this patent is to provide an aerosol generation system that reduces the smell of burnt paper when smoking cigarettes.

[0005] To solve the above-mentioned technical problems, this patent adopts the following technical solution: An aerosol generation system for reducing the smell of heated cigarette paper, the aerosol generation system comprising heated cigarettes and heated smoking devices. Heated cigarettes consist of tobacco segments and adjacent tobacco segments. The tobacco adjacent section is located close to the tobacco section. Tobacco segments are heated in a heated smoking device to form an aerosol that can be inhaled. Heated smoke appliances include heat insulation pipes and heating elements. A channel for airflow to be drawn in is formed between the heat insulation pipe and the heating element; The heating element is arranged at a position 0.1~0.3mm, 0.3~0.5mm, 0.5~0.8mm, 0.8~1.5mm, or 1.5~3mm below the adjacent section of tobacco. The ratio of the length of the heating element to the length of the tobacco segment is 0.95~0.97:1, 0.97~1.00:1, or 1.00~1.05:1.

[0006] Furthermore, the tobacco adjacent segment includes the O-stick segment; Heated smoke appliances also include side vents. The side vents include an inlet vent and an outlet vent. The inlet and outlet holes are respectively located at both ends of the heating element. The airflow enters the channel between the heat insulation tube and the heating element through the inlet hole, and the airflow flows out to the bottom of the tobacco section through the outlet hole.

[0007] Furthermore, the side vents also include flow channel areas. The flow channel is located near the outlet hole, and the airflow flows through the flow channel to the bottom of the tobacco section.

[0008] Furthermore, a bottom cavity is provided at the bottom of the heating element. Airflow enters the bottom cavity from the outlet hole, forming a vortex flow, thus creating a flow channel area where hot and cold air meet at the bottom of the heating element.

[0009] Furthermore, the bottom cavity is spherical in shape.

[0010] Furthermore, the inlet hole is positioned near the connection point between the heated cigarette and the heated smoking device.

[0011] Furthermore, heated smoke appliances also include sealing rings. The sealing rings are located at both the top and bottom ends of the heating element.

[0012] This patent provides an aerosol generation system to reduce the smell of pyrolysis paper. It achieves physical separation of the smoke path and the impurity path at the structural level, improves the purity of inhalation, effectively isolates the undesirable impurities generated by the pyrolysis of cigarette paper, and prevents them from entering the mainstream smoke. Furthermore, it optimizes the relative position of the heating element and the cigarette to prevent non-tobacco sections such as adjacent tobacco sections from being heated and releasing impurities.

[0023] Example 1

[0024] like Figure 1 As shown, traditional external heating devices (i.e., the MOK α infrared heating device from Hubei Tobacco) generally suffer from the problem of smoke and toasted paper smoke sharing a single airflow path. The external airflow passes between the heating element 2 and the cigarette paper of the tobacco section 3, flows through the gap between the heating element 2 and the cigarette paper to the bottom of the tobacco section 3, and then penetrates into the heated cigarette from the bottom of the tobacco section 3 before entering the consumer's mouth. Because the airflow path is close to the cigarette paper, unpleasant impurities generated by the high-temperature toasting of the cigarette paper by the heating element 2 are mixed into the mainstream airflow path of the tobacco section 3 along with the rapid flow of the inhalation airflow, resulting in a poor smoking experience and a strong toasted paper flavor.

[0025] like Figure 2-6As shown, this patent innovatively proposes an "external flow channel" structure, which allows the suction airflow to bypass the outer wall of the heating element 2 and the inner wall of the heat insulation tube 1, and enter from the bottom of the cigarette through the side air hole 5, thus separating the path of the smoke and the paper-burning gas. Furthermore, sealing rings 4 are provided at both ends of the heating element 2 to isolate the airflow gap between the heating tube and the cigarette, preventing airflow from flowing into the suction path through this gap. Simultaneously, the staggered design between the heating element 2 and the cigarette's O-bar segment 73 (support segment) effectively prevents the O-bar segment 73 from being baked, significantly reducing the release of undesirable gases and greatly improving suction comfort.

[0026] A mouthpiece 7 is connected to the top of the tobacco segment 3. The mouthpiece 7 includes a filter segment 71, a cooling segment 72, and an O-rod segment 73 connected sequentially from top to bottom. The O-rod segment 73 serves as the adjacent segment of the tobacco. The heating element 2 is arranged at a position 0.1~0.3mm, 0.3~0.5mm, 0.5~0.8mm, 0.8~1.5mm, or 1.5~3mm below the O-rod segment 73, and the length ratio of the heating element 2 to the length of the tobacco segment 3 is 0.95~1.00:1 or 1.00~1.05:1. In this embodiment, a heating tube is used as the heating element 2 of the heating device, with a length of 12mm. The length of the tobacco segment 3 for heating the cigarette is 12mm. The upper part of the heating element 2 is 0.5mm below the upper end of the tobacco segment 3, and the bottom extends 0.5mm beyond the lower end of the tobacco segment 3, forming a spatially staggered layout of the heating element 2.

[0027] The side air vent 5 includes a flow channel area 51, an inlet hole 52, and an outlet hole 53. The flow channel area 51 is located near the outlet hole 53. The inlet hole 52 and outlet hole 53 are respectively located above and below the heating element 2. External airflow can enter from the connection between the heated cigarette and the heated smoking device, then enter the channel between the heat insulation tube 1 and the heating element 2 through the inlet hole 52, and then flow out from the outlet hole 53 at the bottom of the heating element 2 to penetrate into the interior of the heated cigarette. The side air vent 5 allows airflow to enter between the outer wall of the heating element 2 and the inner wall of the heat insulation tube 1, bypassing the cigarette paper of the tobacco section 3, and flowing from the bottom of the cigarette through the outlet hole 53 into the main airflow path for inhalation, forming an external bypass airflow channel. The inlet hole 52 avoids directly opening a through hole on the surface of the heated smoking device to supply air, preventing heat leakage from affecting the heating effect and improving the smoking experience.

[0028] The heating element 2 and the tobacco section 3 are sealed with sealing rings 4 at the top and bottom to seal off the paper-baking aroma and further reduce the entry of undesirable gases into the mainstream smoke.

[0029] Meanwhile, a bottom cavity 6 is provided at the bottom of the heating element 2 near the side air hole 5. It can be set to a spherical shape. External airflow enters the spherical bottom cavity 6 from the outlet hole 53 and forms a vortex flow. A narrow flow channel area 51 where hot and cold air meet is formed at the bottom of the heating element 2, realizing rapid heat exchange and helping to solve the problem of high temperature of the outer shell of the external heating appliance.

[0052] This comparative example uses an external heating device, which differs from Example 1 in that its heating element length is set to 8mm.

[0053] The upper part of the heating element is 2mm lower than the upper end of the tobacco segment of the heated cigarette, and the bottom part is 2mm lower than the lower end of the tobacco segment.

[0054] To further illustrate the advantages of this patent, the heating performance of the heating devices and cigarettes in the embodiments and comparative examples will be tested below.

[0055] 1. Cigarette pyrolysis detection

[0056] Test method for pyrolysis of cigarette paper: Insert a quartz rod into a quartz tube, fill it with quartz wool and about 2 mg of the sample to be tested, then add 1 μl of n-heptadecane internal standard (2 mg / mL in dichloromethane), and then test the sample.

[0057] The pyrolysis conditions are as follows: Decomposition atmosphere: air; Temperature program: Increase from room temperature to 320℃ / 350℃ at a rate of 20℃ / ms, and hold for 5 minutes; Valve box temperature: 300℃; Transmission line temperature: 300℃.

[0058] The thermal decomposition reaction conditions were set based on the heating curves of the central and peripheral heating devices. The peripheral heating device (Hubei Tobacco's infrared heating device MOK α device) was simulated at 320℃, and the central heating device (Hubei Tobacco's needle-type MOK 2.0 device) was simulated at 350℃. 7.16mm original flavor COO cigarettes were used as test samples for thermal decomposition, and the cigarette paper of 7.16mm original flavor COO cigarettes was also thermally decomposed simultaneously as a control. The smoke generated by thermal decomposition was collected and its composition was analyzed.

[0059] The detection method is as follows: Instrument: Agilent 7890A-5977C GC-MS Inlet temperature: 250℃; constant flow mode, carrier gas flow rate: 1.5 m / min, purge flow rate: 3 m / min; injection volume: 2 μl, split injection, split ratio 50:1, split flow rate 75 mL / min; Column: HP-inmowax (60 m) 0.25 mm 0.25 μm); Temperature program: 40℃, hold for 0 minutes, increase to 120℃ at 20℃ / min, hold for 0 minutes. Increase to 200℃ at 8℃ / min, hold for 5 minutes. Increase to 240℃ at 10℃ / min, hold for 5 minutes.

[0060] Ion source temperature: 230°C; Quadrupole temperature: 150°C; Transmission line temperature: 250°C.

[0061] Scan range: 33~550 amu, solvent delay time: 0 minutes.

[0062] Data analysis: Absolute peak area > 50000. Qualitative analysis was performed using the NIST spectral library, with a qualitative match greater than 80%, further confirmed by the retention index (RI). Relative content was calculated using the internal standard method, where the relative content is the ratio of the component peak area to the internal standard peak area.

[0063] The smoke detection results of the peripherally heated MOK α device, the centrally heated needle-type MOK 2.0 device, and cigarette paper are shown in Table 1.

[0064] Table 1: Composition Analysis of Cigarette Smoke from Peripheral Heating, Central Heating, and Cigarette Paper

[0065] Analysis of the smoke components from peripherally heated, centrally heated, and cigarette paper pyrolysis revealed that 1,2-diacetic acid glycerides were detected in both peripherally heated cigarette smoke and cigarette paper pyrolysis components. Furthermore, the content of this component in the smoke from peripherally heated cigarettes and cigarette paper was significantly higher than that in the centrally heated cigarettes. Therefore, this component is considered to be the source of the negative odor, namely the "toasted paper" smell.

[0066] The heating device of Example 1 was used to heat and inhale 7.16mm original flavor COO cigarettes under pyrolysis conditions at 320℃. The smoke was collected and the 1,2-diacetic acid glyceride content was detected. The results are shown in Table 2.

[0067] Table 2: Analysis of 1,2-diacetic acid glycerides in the smoke from the heater in Example 1

[0068] As shown in Table 2, compared with the MOK α appliance, which is also an external heater, the heating appliance of Example 1 shows a significant decrease in the content of 1,2-diacetic acid glyceride. Therefore, it can be shown that this patent can reduce the smell of baked paper by simultaneously improving and optimizing the external flow and the size and position misalignment of the heating element.

[0069] 2. Sensory evaluation test

[0070] Sensory evaluation tests were conducted on heated cigarettes using existing peripheral heating devices and the peripheral heating device of this patent. Seven tasters conducted sensory evaluations in accordance with the national standard GB 5606.4-2005 Cigarettes Part 4: Sensory Technical Requirements. The final results were recorded as the average score of all participants, as shown in Table 3.

[0071] Table 3: Sensory evaluation results of heating appliances compared with Comparative Examples 1-3 and Example 1

[0072] As can be seen from Table 3, this patent improves the sensory evaluation of cigarettes in all aspects compared with existing peripheral heating devices, and the overall sensory evaluation performance is better. In existing peripheral heating devices, the heating element and the tobacco segment are basically the same length, or the upper part of the heating element is adjacent to or wraps around the O-bar segment, which causes the O-bar segment to be baked and emit impurities, thus affecting the smoking experience of heated cigarettes.

[0073] 3. Aerosol detection

[0074] Heating devices with different heating element lengths from Comparative Examples 4-9 and Example 1 were used to inhale heated cigarettes, and the smoke was collected for aerosol detection. The length of the tobacco segment of the heated cigarette was set to 12 mm.

[0075] Heated cigarettes were inhaled using a heating device. All the smoke was collected from the first puff to the last puff and used as a sample. The process was repeated 5 times in parallel, and the collected smoke was labeled as sample 1-5. The aerosol collection quality was tested, and the results are shown in Table 4.

[0076] Table 4: Results of Aerosol Collection Quality Testing (mg)

[0077] As shown in Table 4, Comparative Examples 4-5 exhibited higher aerosol collection quality, but the sensory evaluation of the vaping experience indicated a more complex smoke profile, and... Figure 12 As shown, the O-segment of Comparative Example 4 exhibits obvious shrinkage deformation.

[0078] The aerosol collection quality of Comparative Examples 6-9 was low, and the sensory evaluation of the vaping experience showed that the smoke was weak and the taste was poor.

[0079] The heated smoking device of Example 1 has a moderate aerosol collection quality, and the sensory evaluation of the smoking experience is that the smoke is relatively balanced and clean, and the O-section shows that it is not baked.

[0080] Therefore, the heated smoking appliance provided in Embodiment 1 of this patent has the following structural improvements and advantages compared to existing smoking appliances: External flow channel structure: to separate the path of flue gas from impurities and prevent the pyrolysis products of cigarette paper from entering the mainstream flue gas; Sealing structure: A sealing ring is installed at the connection between the heating element and the cigarette to prevent the backflow of impurities.

[0081] The bottom spherical cavity and narrow flow channel work together to enhance the efficiency of heat exchange, assist in cooling and settle impurities.

[0082] The heating element and the O-bar segment are staggered: the top of the heating element is 0.5 mm lower than the O-bar segment. Through spatial optimization, the non-tobacco segment is prevented from being heated. This patent proposes an optimized heating element size and position misalignment system. The heating element is 12mm long and the upper part is 0.5mm lower than the O rod, which can effectively avoid the O rod section from baking and reduce the release of unwanted gases.
