Description

Technical Field

[0001] This invention relates to an odor-reducing aerosol-generating article and an aerosol-generating system including the same. Background Technology

[0002] Recently, there has been an increase in demand for alternatives to traditional cigarettes. For example, there is a growing demand for devices that generate aerosols by electrically heating a cigarette stick (e.g., cigarette-type electronic cigarettes). Therefore, research is underway on electrically heated aerosol generating devices and their applications in cigarette sticks (or aerosol generating products).

[0003] However, unlike traditional cigarettes, aerosol generating devices use an electrically heated (so-called electrosteaming) method to heat the tobacco medium, which produces unpleasant odors that users do not want to smell, such as the vapor flavor that is not common in traditional cigarettes.

[0004] Therefore, there is a need for a method to reduce odors such as vapor in aerosol-generating products and aerosol-generating systems including them. Summary of the Invention

[0036] In the following embodiments, "puff" refers to the user's inhalation, which means the inhalation of air into the user's mouth, nasal cavity, or lungs through the user's mouth or nose.

[0037] Figure 1 An aerosol generation system, including an aerosol generating article and an aerosol generating apparatus, is shown according to various embodiments of the present invention.

[0038] Reference Figure 1 According to embodiments of the present invention, an aerosol generating apparatus may include at least one of a power supply 11, a control unit 12, a sensor 13, and a heater 14. At least one of the power supply 11, control unit 12, sensor 13, and heater 14 may be disposed within the body 10 of the aerosol generating apparatus. The body 10 may provide an upwardly opening space for insertion of an aerosol generating article (stick) S. This upwardly opening space may be referred to as an insertion space. The insertion space may be recessed into the body 10 at a predetermined depth to allow at least a portion of the aerosol generating article S to be inserted. The depth of the insertion space may correspond to the length of the region in the aerosol generating article S that includes aerosol generating material and / or tobacco medium. The lower end of the aerosol generating article S may be inserted into the interior of the body 10, and the upper end of the aerosol generating article S may protrude to the exterior of the body 10. A user may place the exposed upper end of the aerosol generating article S in their mouth and inhale air.

[0039] Heater 14 can heat the aerosol-generating article S. In the space where the aerosol-generating article S is inserted, heater 14 can extend upward in an elongated shape. For example, heater 14 may include a tubular heating element, a plate heating element, a needle heating element, or a rod heating element. Heater 14 can be inserted into the lower part of the aerosol-generating article S. Heater 14 may include a resistance heater and / or an induction heater.

[0040] For example, refer to Figure 1 Heater 14 can be a resistance heater. For example, heater 14 includes a conductive track, through which current flows to heat heater 14. Heater 14 can be electrically connected to power supply 11. Heater 14 can directly generate heat by receiving current from power supply 11.

[0041] For example, heater 14 can be multiple heaters. Heater 14 may include a first heater 14A and a second heater 14B. The first heater 14A and the second heater 14B may be arranged side by side in the longitudinal direction. The first heater 14A and the second heater 14B may be heated sequentially or simultaneously.

[0042] For example, an aerosol generating apparatus may include an induction coil surrounding a heater. The induction coil can heat the heater. As a susceptor, the heater 14 can be heated by a magnetic field generated by an alternating current flowing through the induction coil. The magnetic field can pass through the heater and generate eddy currents within it. The current can generate heat within the heater.

[0043] For example, a heat-sensing element may be included inside the aerosol-generating article, and the heat-sensing element inside the aerosol-generating article can be heated by a magnetic field generated by alternating current flowing through an induction coil. The heat-sensing element may be disposed inside the aerosol-generating article and may not be electrically connected to the aerosol-generating device. The heat-sensing element may be inserted into an insertion space together with the aerosol-generating article and may be removed from the insertion space together with the aerosol-generating article. The aerosol-generating article may be heated by the heat-sensing element inside the aerosol-generating article. In this case, the aerosol-generating device may not include a heater.

[0044] Power source 11 supplies electricity to activate the components of the aerosol generating apparatus. Power source 11 may be referred to as a battery. Power source 11 can supply power to at least one of the control unit 12, sensor 13, and heater 14. Power source 11 can supply power to the induction coil.

[0045] The control unit 12 can control the overall operation of the aerosol generating device. The control unit can be mounted on a printed circuit board (PCB). The control unit 12 can control the operation of at least one of the power supply 11, sensor 13, and heater 14. The control unit 12 can control the operation of the induction coil. The control unit 12 can control the operation of the display, motor, etc., installed in the aerosol generating device. The control unit 12 can check the status of each component of the aerosol generating device to determine whether the aerosol generating device is in an operational state.

[0046] The control unit 12 can analyze the sensing results of the sensor 13 and control subsequent processing. For example, the control unit 12 can control the power supplied to the heater 14 based on the sensing results of the sensor 13, thereby starting or stopping the operation of the heater 14. As another example, the control unit 12 can control the amount of power supplied to the heater 14 and the power supply time based on the sensing results of the sensor 13, so that the heater 14 heats up to a predetermined temperature or maintains a suitable temperature.

[0047] Sensor 13 may include at least one of a temperature sensor, a suction sensor, an insertion sensing sensor, and an acceleration sensor. For example, sensor 13 may sense at least one of the temperature of heater 14, the temperature of power supply 11, or the internal and external temperatures of body 10. For example, sensor 13 may sense the user's puff. For example, sensor 13 may sense whether the aerosol generating article S is inserted into the insertion space. For example, sensor 13 may sense the movement of the aerosol generating device.

[0048] Figure 2 The diagram schematically illustrates the structure of an aerosol generation article comprising a dual composite filter containing activated carbon according to an embodiment of the present invention.

[0049] Reference Figure 2According to one embodiment, the aerosol generating article may include a tobacco medium section and a filter section, the filter section corresponding to a dual composite filter, which is composed of a filter including activated carbon and a filter including cellulose acetate. Additionally, it may include a tubular filter and a branch filter. The filter including activated carbon may include 6 to 12 mg, preferably 8 to 12 mg, more preferably 10 to 12 mg of activated carbon, and most preferably 12 mg of activated carbon, especially super-activated carbon. When the filter according to an embodiment of the present invention includes the above-mentioned amount of activated carbon, the transfer of odor-causing nitrogen compounds, such as pyridine, pyrrole, 3-methylpyridine, 3-vinylpyridine, 2-methylpyridine, 4-methylpyridine, etc., can be effectively reduced, and the specific effects will be described in detail with reference to the following embodiments.

[0050] The dual composite filter can be divided into a filter including activated carbon and a filter including cellulose acetate. From the perspective of effectively reducing the total nitrogen transfer, it is preferable to place the filter section at the lower end of the tobacco medium section. Specifically, in the dual composite filter, the filter including activated carbon is placed at the upper end of the filter including cellulose acetate.

[0051] Furthermore, the length of the dual composite filter can be 5 to 14 mm, preferably 12 mm. The lengths of the filter comprising activated carbon and the filter comprising cellulose acetate can each be 5 to 7 mm, preferably 6 mm.

[0052] In addition, the filter section may also include a paper filter treated with medium chain triglycerides (MCTG), which can be added to and applied to existing filters, such as the dual composite filter described above.

[0053] In one embodiment, the aerosol-generating article may be wrapped in at least one piece of packaging paper. The packaging paper may have at least one hole (perforation) for the inflow of external air or the outflow of internal gas. The packaging paper may comprise a material with high thermal conductivity.

[0054] For example, the tobacco medium section can be wrapped with medium wrapping paper (Tobacco Plug Wrapper), the dual composite filter can be wrapped with cellulose acetate filter wrapping paper (Filter Plug Wrapper), and dual composite filters and tubular filters can also be wrapped with tipping paper. Furthermore, the entire aerosol-generating product can be wrapped again with final outer wrapping paper (Multi-Final Wrapper).

[0055] In one embodiment, the at least one packaging paper can be formed from porous packaging paper, polylactic acid (PLA) laminated paper, sterilized paper, etc. For example, the porosity of the packaging paper can be 35000 CU, but is not limited to this. Additionally, the thickness of the packaging paper can be between 60 μm and 100 μm. Furthermore, the basis weight of the packaging paper can be 40 g / m³. 2 Up to 80g / m 2 Within the range.

[0056] For example, packaging paper may include an aluminum component. For example, packaging paper may be a combination of ordinary filter packaging paper and metal foil (e.g., aluminum foil).

[0057] In one embodiment, the tobacco medium portion may include a cavity that may be filled with tobacco medium. The tobacco medium may include tobacco leaves and auxiliary materials, the auxiliary materials being materials formed from one or more of guar gum, pulp, glycerin, and a shell. The shell may be a flavoring type commonly used in the industry.

[0058] The content of tobacco leaves and auxiliary materials constituting the tobacco medium, relative to the total weight of the tobacco medium, may include 60 to 65% by weight of tobacco leaves and 35 to 40% by weight of auxiliary materials.

[0059] Furthermore, to reduce the amount of total nitrogen transferred from the aerosol, the tobacco medium filled in the tobacco medium portion may include tobacco leaves with a low total nitrogen content of 2.5% by weight or less, and the tobacco medium can be obtained by mixing two types of tobacco leaves with the aforementioned low total nitrogen content. For example, the tobacco leaves may be a mixture of the following: 15 to 20 parts by weight of Philippine flue-cured tobacco leaves, wherein the tobacco leaves contain 2.40% to 2.60% by weight of nicotine and 2.20% to 2.40% by weight of total nitrogen; 5 to 20 parts by weight of Philippine flue-cured tobacco leaves, wherein the tobacco leaves contain 2.05% to 2.25% by weight of nicotine and 1.60% to 1.80% by weight of total nitrogen; and 0 to 20 parts by weight of Korean flue-cured tobacco leaves, wherein the tobacco leaves contain 2.05% to 2.25% by weight of nicotine and 1.60% to 1.80% by weight of total nitrogen; and 0 to 20 parts by weight of Korean flue-cured tobacco leaves, wherein the tobacco leaves contain 2.05% to 2.25% by weight of nicotine and 1.60% to 1.80% by weight of total nitrogen. The nicotine content is 0.01% to 0.20% by weight, and the total nitrogen content is 1.70% to 1.90% by weight; 5 parts by weight to 15 parts by weight of Tanzanian flue-cured tobacco leaves, with a nicotine content of 2.05% to 2.25% by weight and a total nitrogen content of 2.05% to 2.25% by weight; and 0 parts by weight to 20 parts by weight of Malawi flue-cured tobacco leaves, with a nicotine content of 2.80% to 3.00% by weight and a total nitrogen content of 2.15% to 2.35% by weight.

[0060] Typically, even if the total nitrogen content of tobacco leaves is low, the amount of total nitrogen transferred is not low. Therefore, the above-mentioned blend of tobacco leaves can be considered as a combination that effectively reduces the amount of total nitrogen transferred.

[0061] In addition, in one embodiment, the average particle size of the tobacco medium may be 30 to 40 μm, and the proportion of particles with a particle size of less than 80 μm may be more than 90% of the total number of particles.

[0062] The structure and effects of the present invention will now be described in more detail through embodiments and comparative examples. However, these embodiments are used to illustrate the present invention in more detail, and the scope of the present invention is not limited to these embodiments.

[0063] -Example

[0064] 1) Preparation Example 1: Preparation of Tobacco Medium

[0065] The tobacco leaves shown in Table 1 below were selected as tobacco leaf types with a total nitrogen content of 2.5% by weight or less, and were mixed according to the mixing ratios shown in Table 2 below to prepare tobacco medium. Meanwhile, Comparative Example 1 involves currently used tobacco medium mixing.

[0066] [Table 1]

[0067]

[0068] [Table 2]

[0069]

[0070]

[0071] *The particle size distribution above represents the proportion of particles with a diameter of less than 80 μm.

[0072] 2) Preparation Example 2: Manufacturing of Aerosol-Generated Products

[0073] a) Preparation Example 2-1: Manufacturing an aerosol-generating article including a filter containing activated carbon

[0074] as follows Figure 2 As shown, a cellulose acetate filter is manufactured using a 6mm filter containing 12mg of activated carbon (super activated carbon, SAC) and a 6mm cellulose acetate filter. The filter includes a 12mm tobacco medium section containing the mixed tobacco medium manufactured in Example 1 above, a 10mm tubular filter, and a 14mm branch filter. Packaging paper is used to manufacture an aerosol-generating product.

[0075] b) Preparation Example 2-2: Manufacturing an aerosol-generating product including a filter without activated carbon

[0076] Except for manufacturing a 12mm cellulose acetate filter without activated carbon, an aerosol-generating product was manufactured in the same manner as in Preparation Example 2-1.

[0077] 3) Experimental Example 1: Component Analysis of Tobacco Leaves in Each Mix

[0078] The components of the tobacco leaves in the mixtures prepared in Preparation Example 1 (Comparative Example 1 and Examples 1 to 3) were analyzed, and the results are shown in Table 3 below. Figure 3 As shown.

[0079] [Table 3]

[0080]

[0081] *Unit is weight%.

[0082] As can be seen from Table 3 above, the total nitrogen content also shows an upward trend as the nicotine content in tobacco leaves increases.

[0083] 4) Experimental Example 2: Aerosol Composition Analysis in Each Mixture

[0084] The aerosol components in each mixture were analyzed by applying the tobacco medium manufactured in Preparation Example 1 to the aerosol-generating articles manufactured in Preparation Examples 2-1 and 2-2. The results are shown in Table 4 below, where the results for nicotine and glycerin are as follows: Figure 4a and Figure 4b As shown.

[0085] [Table 4]

[0086]

[0087] Refer to Table 4 and Figure 4a , Figure 4b It can be confirmed that, compared with the case of using only a cellulose acetate filter without an activated carbon dual composite filter (Preparation Example 2-2), when using an activated carbon dual composite filter (Preparation Example 2-1), the content of aerosol components such as nicotine and glycerin is slightly reduced, and the decrease in glycerin content is relatively smaller than the decrease in nicotine content.

[0088] Furthermore, by comparing the various mixtures, it was found that when using the mixed tobacco media of Examples 1 to 3, the nicotine content was reduced compared to the mixed tobacco media of Comparative Example 1 currently in use. Moreover, the nicotine content reduction was greater in Examples 1 and 2, but the glycerol content reduction was greater in Example 1 than in Example 2.

[0089] 5) Experimental Example 3: Analysis of Nitrogen Transfer Amount

[0090] In the same manner as in Experimental Example 4, the amount of nitrogen transferred from the aerosol-generated product was analyzed for each mixing and filtration. The reduction rate of total nitrogen content compared to Comparative Example 1 was calculated, and the results are shown in Table 5 below. Figure 5a and Figure 5b As shown.

[0091] [Table 5]

[0092]

[0093]

[0094] *The unit of transfer amount is μg.

[0095] Refer to Table 5 and Figure 5a and Figure 5b As can be seen, in Examples 1 to 3, which use low-total-nitrogen tobacco leaves with a total nitrogen content of less than 2.5% by weight, the amount of total nitrogen transferred is reduced by up to 38%. This demonstrates that the odor-reducing blended tobacco medium according to the embodiments of the present invention has an excellent effect in reducing vapor odor. Furthermore, when a dual composite filter containing 12 mg of activated carbon is applied together with the aforementioned tobacco medium to an aerosol-generating product, the amount of total nitrogen transferred can be reduced by 50% to 60%, and an excellent effect of significantly reducing odor components (nitrogen compounds) can be achieved. Especially when using the tobacco medium and dual composite filter of Example 2, the coordination and balance are excellent, allowing the user to experience greater satisfaction from smoking.

[0096] The above embodiments are merely illustrative, and those skilled in the art will understand that various modifications and equivalent variations can be made thereto. Therefore, the scope of this disclosure should be defined by the appended claims, and all differences within the scope equivalent to that described in the claims will be interpreted as included within the protection scope defined by the claims.

[0097] Without causing obvious technical conflict, the features and aspects of any of the above embodiments may be combined with the features and aspects of any other embodiments.
