Description

열전도성 물질을 포함하는 에어로졸 생성 물품Aerosol-generating article comprising thermally conductive material
본 개시는 열전도성 물질을 포함하는 에어로졸 생성 물품에 관한 것이다.The present disclosure relates to an aerosol-generating article comprising a thermally conductive material.
근래에 일반적인 궐련의 단점들을 극복하는 대체 방법에 관한 수요가 증가하고 있다. 예를 들어, 궐련을 연소시켜 에어로졸을 생성하는 방법이 아닌, 에어로졸 생성 장치를 이용하여 궐련 또는 에어로졸 생성 물질을 가열함으로써 에어로졸을 생성하는 시스템에 관한 수요가 증가하고 있다. In recent years, there has been an increasing demand for alternative methods that overcome the disadvantages of conventional cigarettes. For example, there is a growing demand for systems that generate aerosols by heating cigarettes or aerosol-generating materials using an aerosol-generating device, rather than by burning a cigarette to generate an aerosol.
한편, 궐련을 가열하여 에어로졸을 생성하는 시스템에 있어서, 사용자에게 풍부한 양의 에어로졸을 제공하고, 최적의 흡연 경험을 제공하기 위해서는 궐련을 가열하는 과정에서의 열 전달 효율을 증가시킬 필요가 있다.Meanwhile, in a system for generating an aerosol by heating a cigarette, it is necessary to increase the heat transfer efficiency in the process of heating the cigarette in order to provide a user with an abundant amount of aerosol and provide an optimal smoking experience.
다양한 실시예들은 열전도성 물질을 포함하는 에어로졸 생성 물품을 제공하는데 있다. 본 개시가 이루고자 하는 기술적 과제는 상기된 바와 같은 기술적 과제들로 한정되지 않으며, 이하의 실시예들로부터 또 다른 기술적 과제들이 유추될 수 있다.Various embodiments are directed to providing an aerosol-generating article comprising a thermally conductive material. The technical problems to be achieved by the present disclosure are not limited to the technical problems as described above, and other technical problems may be inferred from the following embodiments.
다양한 실시예들은 담배 분말 및 열전도성 분말을 포함하는 혼합물로부터 제조되는 담배 매질부를 포함하고, 상기 혼합물은 건조 중량 기준으로 20 중량% 미만의 열전도성 분말을 포함하는 에어로졸 생성 물품을 제공할 수 있다.Various embodiments can provide an aerosol-generating article comprising a tobacco medium prepared from a mixture comprising tobacco powder and a thermally conductive powder, the mixture comprising less than 20% by weight on a dry weight basis of the thermally conductive powder.
본 개시는 열전도성 물질을 포함하는 에어로졸 생성 물품을 제공할 수 있다. 구체적으로, 본 개시에 따른 에어로졸 생성 물품은 담배 분말 및 열전도성 분말을 포함하는 혼합물로부터 제조되는 담배 매질부를 포함할 수 있다. 담배 매질부에 열전도성 물질이 포함됨에 따라 에어로졸 생성 물품이 가열되는 과정에서의 열 전달 효율이 증가될 수 있다. 이에 따라, 풍부한 양의 에어로졸이 사용자에게 제공될 수 있고, 예열을 위해 필요한 시간 및 배터리의 전력 소모가 감소될 수 있다.The present disclosure may provide an aerosol-generating article comprising a thermally conductive material. Specifically, an aerosol-generating article according to the present disclosure may comprise a tobacco medium prepared from a mixture comprising tobacco powder and a thermally conductive powder. The inclusion of the thermally conductive material in the tobacco medium may increase the heat transfer efficiency in the process of heating the aerosol-generating article. Accordingly, an abundant amount of aerosol can be provided to the user, and the time required for warm-up and power consumption of the battery can be reduced.
다만, 담배 매질부에 너무 많은 양의 열전도성 물질이 포함되는 경우, 에어로졸 생성 물품이 가열되는 과정에서 담배 매질부의 온도가 기 설정된 온도 프로파일에 의해 의도된 수준보다 높게 상승됨에 따라, 사용자에게 지나친 열감이 전달될 수 있다. 도 6 내지 도 8을 참조하여 후술할 실험 결과에 따르면, 혼합물에 포함되는 열전도성 분말이 건조 중량 기준으로 20 중량% 이상인 경우, 초기 퍼프 구간에서 사용자에게 지나친 열감이 전달된다는 사실이 확인되었다. 이에 따라, 본 개시에 따른 에어로졸 생성 물품의 담배 매질부를 제조하기 위한 혼합물은 건조 중량 기준으로 20 중량% 미만의 열전도성 분말을 포함할 수 있다. 따라서, 에어로졸 생성 물품이 가열되는 과정에서의 열 전달 효율이 증가되면서도, 기 설정된 온도 프로파일에 의해 의도된 수준으로 담배 매질부의 온도가 제어될 수 있다.However, when the tobacco medium contains too much thermally conductive material, the temperature of the tobacco medium rises higher than the intended level by the preset temperature profile in the process of heating the aerosol-generating article, giving the user an excessive sense of heat. This can be passed on. According to the experimental results to be described later with reference to FIGS. 6 to 8 , when the thermally conductive powder included in the mixture is 20% by weight or more based on the dry weight, it was confirmed that an excessive sense of heat is transmitted to the user in the initial puff section. Accordingly, the mixture for preparing the tobacco medium of an aerosol-generating article according to the present disclosure may comprise less than 20% by weight on a dry weight basis of the thermally conductive powder. Accordingly, the temperature of the tobacco medium can be controlled to an intended level by the preset temperature profile while the heat transfer efficiency in the process of heating the aerosol-generating article is increased.

The first part described above may include an aerosol generating unit 210 and a tobacco medium 220 , and the second part may include a cooling unit 230 and a filter unit 240 .
에어로졸 생성부(210)는 담배 매질부(220)의 상류에 배치되고, 보습제가 도포된 비담배 물질의 시트를 포함할 수 있다. 보습제는 에어로졸 생성 물질에 대응될 수 있다. 예를 들어, 보습제는 글리세린, 프로필렌 글리콜, 에틸렌 글리콜, 디프로필렌 글리콜, 디에틸렌 글리콜, 트리에틸렌 글리콜, 테트라에틸렌 글리콜 및 올레일 알코올 중 적어도 하나를 포함할 수 있으나, 이에 한정되지 않는다. 비담배 물질은 담배 물질이 아닌 물질로서, 보습제를 흡수할 수 있는 고분자 소재 또는 셀룰로오스 물질일 수 있다. 예를 들어, 비담배 물질의 시트는 고온으로 가열되더라도 열에 의한 이취가 발생되지 않는 종이 시트일 수 있다. 다만, 이에 제한되는 것은 아니다.The aerosol generator 210 is disposed upstream of the tobacco medium 220 and may include a sheet of non-tobacco material to which a moisturizing agent is applied. The humectant may correspond to an aerosol generating material. For example, the moisturizer may include, but is not limited to, at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. The non-tobacco material is a material that is not a tobacco material, and may be a polymer material or a cellulosic material capable of absorbing a moisturizing agent. For example, the sheet of non-tobacco material may be a paper sheet that does not generate off-flavor due to heat even when heated to a high temperature. However, the present invention is not limited thereto.
한편, 에어로졸 생성부(210)는 권축되거나 압착됨에 따라 주름진 시트를 포함할 수 있고, 권축되지 않은 채로 말려진 시트를 포함할 수도 있다. 다만, 이에 제한되는 것은 아니며, 에어로졸 생성부(210)는 임의의 적절한 형태를 갖는 비담배 물질의 시트를 포함할 수 있다. 에어로졸 생성부(210)는 풍미제, 습윤제 등과 같은 다른 첨가 물질을 함유할 수 있다. 예를 들어, 멘솔 또는 보습제 등의 가향액이 에어로졸 생성부(210)에 분사됨으로써 첨가될 수 있다.On the other hand, the aerosol generating unit 210 may include a sheet wrinkled as it is crimped or compressed, and may include a sheet rolled without being crimped. However, the present invention is not limited thereto, and the aerosol generating unit 210 may include a sheet of non-tobacco material having any suitable shape. The aerosol generator 210 may contain other additive substances such as flavoring agents, wetting agents, and the like. For example, a flavoring liquid such as menthol or a moisturizer may be added by being sprayed on the aerosol generating unit 210 .
담배 매질부(220)는 담배 분말 및 열전도성 분말을 포함하는 혼합물로부터 제조될 수 있다. 혼합물은 첨가제, 바인더 및 보습제 중 적어도 하나를 더 포함하고, 담배 매질부(220)는 혼합물에 물을 첨가하여 배합함에 따라 생성되는 슬러리를 시트 형태로 건조한 뒤, 성형하는 방식으로 제조될 수 있다. 예를 들어, 혼합물은 담배 분말, 열전도성 금속 분말(예를 들어, 알루미늄), 비담배 섬유 첨가제(예를 들어, 펄프) 및 외인성 바인더(예를 들어, 구아검)를 고형분으로 포함하고, 보습제(예를 들어, 글리세린)를 더 포함할 수 있다. Tobacco medium 220 may be manufactured from a mixture comprising tobacco powder and thermally conductive powder. The mixture further includes at least one of an additive, a binder, and a humectant, and the tobacco medium 220 may be manufactured by drying the slurry produced by adding water to the mixture to form a sheet and then molding it. For example, the mixture comprises tobacco powder, a thermally conductive metal powder (eg, aluminum), a non-tobacco fiber additive (eg, pulp) and an exogenous binder (eg, guar gum) as solids, and a humectant (eg, glycerin) may be further included.
담배 매질부(220)는 다양하게 성형될 수 있다. 예를 들어, 담배 매질부(220)는 시트(sheet) 자체로 제작될 수도 있다. 이 경우 담배 매질부(220)는 권축되거나 압착됨에 따라 주름진 시트로 제작될 수 있고, 권축되지 않은 채로 말려질(rolled) 수도 있다. 담배 매질부(220)는 시트가 절단된 가닥(strand)으로 제작될 수 있고, 시트가 잘게 잘린 각초로 제작될 수도 있다. Tobacco medium 220 may be formed in various ways. For example, the tobacco medium 220 may be manufactured as a sheet itself. In this case, the tobacco medium 220 may be manufactured as a corrugated sheet as it is crimped or compressed, and may be rolled without being crimped. Tobacco medium 220 may be made of a sheet cut strand (strand), it may be made of cut sheet cut into pieces.
한편, 담배 매질부(220)에 열전도성 물질(예를 들어, 열전도성 분말)이 포함됨에 따라 에어로졸 생성 물품(20000)이 가열되는 과정에서의 열 전달 효율이 증가될 수 있다. 이에 따라, 풍부한 양의 에어로졸이 사용자에게 제공될 수 있고, 예열을 위해 필요한 시간 및 배터리의 전력 소모가 감소될 수 있다.On the other hand, as the tobacco medium 220 includes a thermally conductive material (eg, thermally conductive powder), heat transfer efficiency in the process of heating the aerosol-generating article 20000 may be increased. Accordingly, an abundant amount of aerosol can be provided to the user, and the time required for warm-up and power consumption of the battery can be reduced.
다만, 담배 매질부(220)에 너무 많은 양의 열전도성 물질이 포함되는 경우, 에어로졸 생성 물품(20000)이 가열되는 과정에서 담배 매질부(220)의 온도가 기 설정된 온도 프로파일에 의해 의도된 수준보다 높게 상승됨에 따라, 사용자에게 지나친 열감이 전달될 수 있다. 따라서, 담배 매질부(220)에는 너무 많지 않은 양의 열전도성 물질이 포함될 필요가 있다. 이하 도 6 내지 도 8을 참조하여 열전도성 분말의 적절한 함량에 대해 설명한다.However, when the tobacco medium 220 contains too much of a thermally conductive material, the temperature of the tobacco medium 220 in the process of heating the aerosol-generating article 20000 is the level intended by the preset temperature profile. As it rises higher, excessive heat sensation may be transmitted to the user. Accordingly, the tobacco medium 220 needs to contain a thermally conductive material in an amount that is not too large. Hereinafter, an appropriate content of the thermally conductive powder will be described with reference to FIGS. 6 to 8 .

에어로졸 생성 물품 C, 에어로졸 생성 물품 A5, 에어로졸 생성 물품 A10, 에어로졸 생성 물품 A15 및 에어로졸 생성 물품 A20 각각은 혼합물의 중량을 100이라고 할 때, 500에 대응되는 중량을 갖는 물과 혼합됨에 따라 생성되는 슬러리로부터 제조되는 담배 매질부를 포함한다.Aerosol-generating article C, aerosol-generating article A5, aerosol-generating article A10, aerosol-generating article A15 and aerosol-generating article A20 each have a slurry produced by mixing with water having a weight corresponding to 500, when the weight of the mixture is 100 It includes a tobacco medium prepared from.
도 7의 표를 참조하면, 전술한 에어로졸 생성 물품들을 가열하는 경우, 각각의 에어로졸 생성 물품으로부터 생성되는 에어로졸의 성분 분석 결과가 도시되어 있다.Referring to the table of FIG. 7 , when the aforementioned aerosol-generating articles are heated, the results of analysis of components of an aerosol generated from each aerosol-generating article are shown.
도 7을 참조하면, 에어로졸 생성 물품에 포함되는 알루미늄 분말의 함량이 증가함에 따라 TPM(Total Particulate Matter), 니코틴, 글리세린 등과 같은 연기 성분의 이행량이 증가됨을 알 수 있다. 다시 말해, 에어로졸 생성 물품에 포함되는 알루미늄 분말의 함량이 증가함에 따라 보다 풍부한 양의 에어로졸이 사용자에게 제공될 수 있고, 예열을 위해 필요한 시간 및 배터리의 전력 소모가 감소될 수 있음을 알 수 있다. 다만, 이하 도 8을 참조하여 후술할 바와 같이, 알루미늄 분말의 함량이 더 많은 것이 반드시 바람직한 것은 아닐 수 있다.Referring to FIG. 7 , as the content of aluminum powder included in the aerosol-generating article increases, it can be seen that the transfer amount of smoke components such as TPM (Total Particulate Matter), nicotine, and glycerin is increased. In other words, it can be seen that as the content of aluminum powder included in the aerosol-generating article increases, a more abundant amount of aerosol can be provided to the user, and the time required for preheating and power consumption of the battery can be reduced. However, as will be described later with reference to FIG. 8 , it may not necessarily be preferable that the content of the aluminum powder is higher.
도 8의 그래프를 참조하면, 히터가 기 설정된 온도 프로파일에 따라 가열되는 경우, 전술한 에어로졸 생성 물품들 각각에 포함되는 담배 매질부의 온도를 측정한 결과가 도시되어 있다.Referring to the graph of FIG. 8 , when the heater is heated according to a preset temperature profile, a result of measuring the temperature of the tobacco medium included in each of the aforementioned aerosol-generating articles is shown.
기 설정된 온도 프로파일에 따르면, 에어로졸 생성 물품을 가열하는 히터는 0 내지 40초 구간 동안 270도로 가열되고, 40초 내지 60초 구간 동안 240도로 가열되며, 60초 내지 80초 구간 동안 235도로 가열되고, 80초 내지 280초 구간 동안 230도로 가열될 수 있다. 기 설정된 온도 프로파일은 히터와 접촉하지 않는, 담배 매질부의 말단 부분의 목표 온도가 170도 이상이 되도록 설정된 것일 수 있다.According to the preset temperature profile, the heater for heating the aerosol-generating article is heated to 270 degrees for a period of 0 to 40 seconds, heated to 240 degrees for a period of 40 seconds to 60 seconds, and heated to 235 degrees for a period of 60 seconds to 80 seconds, It may be heated to 230 degrees for a period of 80 seconds to 280 seconds. The preset temperature profile may be set such that the target temperature of the end portion of the tobacco medium, which is not in contact with the heater, is 170 degrees or more.
도 8을 참조하면, 에어로졸 생성 물품 C, 에어로졸 생성 물품 A5, 에어로졸 생성 물품 A10 및 에어로졸 생성 물품 A15는 기 설정된 온도 프로파일에 의해 의도된 수준으로 온도가 제어됨을 알 수 있다. 이에 반해, 에어로졸 생성 물품 A20은 초기 퍼프 구간에서 온도가 과도하게 상승됨을 알 수 있다.Referring to FIG. 8 , it can be seen that aerosol-generating article C, aerosol-generating article A5, aerosol-generating article A10, and aerosol-generating article A15 are temperature controlled to an intended level by a preset temperature profile. In contrast, in the aerosol-generating article A20, it can be seen that the temperature is excessively increased in the initial puff section.
이와 같이, 담배 매질부에 너무 많은 양(즉, 20 중량% 이상)의 열전도성 물질이 포함되는 경우, 에어로졸 생성 물품이 가열되는 과정에서 담배 매질부의 온도가 기 설정된 온도 프로파일에 의해 의도된 수준보다 높게 상승됨에 따라, 사용자에게 지나친 열감이 전달될 수 있음을 알 수 있다. 따라서, 담배 매질부를 제조하기 위한 혼합물은 20 중량% 미만의 열전도성 물질을 포함하는 것이 바람직할 수 있다.As such, when the tobacco medium contains an excessively large amount (ie, 20% by weight or more) of the thermally conductive material, the temperature of the tobacco medium is higher than the level intended by the preset temperature profile in the process of heating the aerosol-generating article. As it rises high, it can be seen that excessive heat sensation can be transmitted to the user. Accordingly, it may be preferred that the mixture for preparing the tobacco medium comprises less than 20% by weight of the thermally conductive material.
다시 도 5로 돌아와서, 본 개시에 따른 에어로졸 생성 물품(20000)의 담배 매질부(220)를 제조하기 위한 혼합물은 건조 중량 기준으로 20 중량% 미만의 열전도성 분말을 포함할 수 있다. 따라서, 에어로졸 생성 물품(20000)이 가열되는 과정에서의 열 전달 효율이 증가되면서도, 기 설정된 온도 프로파일에 의해 의도된 수준으로 담배 매질부(220)의 온도가 제어될 수 있다.5 , the mixture for making the tobacco medium 220 of the aerosol generating article 20000 according to the present disclosure may comprise less than 20% by weight of the thermally conductive powder on a dry weight basis. Accordingly, while the heat transfer efficiency in the process of heating the aerosol-generating article 20000 is increased, the temperature of the tobacco medium 220 may be controlled to an intended level by the preset temperature profile.
예를 들어, 혼합물은 건조 중량 기준으로 30 중량% 내지 80 중량%의 담배 분말, 및 0.1 중량% 이상 20 중량% 미만의 열전도성 분말을 포함할 수 있다. 보다 구체적으로, 혼합물은 건조 중량 기준으로 60 중량% 내지 80 중량%의 담배 분말, 5 중량% 이상 20 중량% 미만의 열전도성 분말, 3 중량% 내지 7 중량%의 첨가제, 6 중량% 내지 10 중량%의 바인더, 및 5 중량% 내지 12 중량%의 보습제를 포함할 수 있다. 다만, 이에 반드시 제한되는 것은 아니며, 열전도성 분말의 함량이 20% 중량 미만이라면, 다른 재료들의 함량은 적절하게 변경될 수도 있다.For example, the mixture may comprise 30% to 80% by weight of tobacco powder on a dry weight basis, and at least 0.1% but less than 20% by weight of the thermally conductive powder. More specifically, the mixture comprises, on a dry weight basis, 60% to 80% by weight of tobacco powder, at least 5% to less than 20% by weight of thermally conductive powder, from 3% to 7% by weight of additives, from 6% to 10% by weight. % binder, and 5% to 12% by weight of a humectant. However, the present invention is not necessarily limited thereto, and if the content of the thermally conductive powder is less than 20% by weight, the content of other materials may be appropriately changed.
한편, 담배 매질부(220)로부터 생성되는 에어로졸의 특성은 담배 매질부(220)에 포함되는 열전도성 분말의 함량뿐만 아니라 분포에 의해서도 달라질 수 있다. 이하 도 9 및 도 10을 참조하여 열전도성 분말의 바람직한 분포에 대해 설명한다.On the other hand, the characteristics of the aerosol generated from the tobacco medium 220 may vary depending on the distribution as well as the content of the thermally conductive powder contained in the tobacco medium 220. Hereinafter, a preferred distribution of the thermally conductive powder will be described with reference to FIGS. 9 and 10 .
도 9 및 도 10은 예시적인 실시예들에 따른 담배 매질부 내 열전도성 분말의 분포를 설명하기 위한 단면도이다.9 and 10 are cross-sectional views for explaining the distribution of the thermally conductive powder in the tobacco medium according to exemplary embodiments.
도 9를 참조하면, 에어로졸 생성 물품이 담배 매질부(220)의 외부로부터 전달되는 열에 의해 가열되는 경우의 열전도성 분말(910)의 바람직한 분포의 예시가 도시되어 있다.Referring to FIG. 9 , there is shown an example of a preferred distribution of the thermally conductive powder 910 when the aerosol-generating article is heated by heat transferred from the outside of the tobacco medium 220 .
에어로졸 생성 물품이 담배 매질부(220)의 외부로부터 전달되는 열에 의해 가열된다는 것은 도 2 내지 도 4에 도시된 바와 같이, 히터가 담배 매질부(220)의 외부를 둘러싸도록 배치된다는 것을 의미할 수 있다. 일반적으로 히터가 담배 매질부(220)의 외부를 둘러싸도록 배치되는 경우, 담배 매질부(220)의 중심 영역(920)의 온도가 담배 매질부(220) 내의 다른 영역(즉, 중심 영역(920)이 아닌 영역)의 온도보다 낮을 수 있다. 이에 따라, 중심 영역(920)보다 다른 영역에 포함된 에어로졸 생성 물질이 더 빠르게 고갈될 수 있다. The fact that the aerosol-generating article is heated by heat transmitted from the outside of the tobacco medium 220 may mean that the heater is disposed to surround the outside of the tobacco medium 220 as shown in FIGS. 2 to 4 . have. In general, when the heater is disposed to surround the outside of the tobacco medium 220, the temperature of the central region 920 of the tobacco medium 220 is different in the tobacco medium 220 (ie, the central region 920). ) may be lower than the temperature of the region). Accordingly, the aerosol-generating material included in the other region than the central region 920 may be depleted more rapidly.
예시적인 실시예에 따르면, 열전도성 분말(910)은 담배 매질부(220)의 길이 방향 축(즉, 도 9의 단면도에 도시된 담배 매질부(220)의 중심)에 가까울수록 더 높은 밀도로 분포될 수 있다. 이에 따라, 에어로졸 생성 물품과 함께 사용되는 에어로졸 생성 장치가 외부 가열 방식의 히터를 포함하더라도, 담배 매질부(220)는 전체적으로 균일하게 가열될 수 있다. 일 예에서, 담배 매질부(220)의 중심 영역(920)에 포함되는 열전도성 분말의 양은 담배 매질부(220)의 다른 영역에 포함되는 분말의 양보다 2배 이상 많을 수 있다. 다만, 이에 반드시 제한되는 것은 아니다. 한편, 중심 영역(920)은 담배 매질부(220)의 직경의 절반에 해당하는 영역일 수 있으나, 이에 제한되는 것은 아니다.According to an exemplary embodiment, the thermally conductive powder 910 has a higher density the closer to the longitudinal axis of the tobacco medium 220 (ie, the center of the tobacco medium 220 shown in the cross-sectional view of FIG. 9 ). can be distributed. Accordingly, even if the aerosol-generating device used together with the aerosol-generating article includes an external heating type heater, the tobacco medium 220 can be uniformly heated as a whole. In one example, the amount of the thermally conductive powder included in the central region 920 of the tobacco medium 220 may be twice or more than the amount of powder included in other regions of the tobacco medium 220 . However, the present invention is not necessarily limited thereto. Meanwhile, the central region 920 may be a region corresponding to half the diameter of the tobacco medium 220 , but is not limited thereto.
도 10을 참조하면, 에어로졸 생성 물품이 담배 매질부(220)의 내부로부터 전달되는 열에 의해 가열되는 경우의 열전도성 분말(1010)의 바람직한 분포의 예시가 도시되어 있다.Referring to FIG. 10 , an example of a preferred distribution of the thermally conductive powder 1010 is shown when the aerosol generating article is heated by heat transferred from the interior of the tobacco medium 220 .
에어로졸 생성 물품이 담배 매질부(220)의 내부로부터 전달되는 열에 의해 가열된다는 것은 도 1에 도시된 바와 같이, 히터가 담배 매질부(220)의 내부에 삽입되도록 배치된다는 것을 의미할 수 있다. 일반적으로 히터가 담배 매질부(220)의 내부에 삽입되는 경우, 담배 매질부(220)의 중심 영역(1020)의 온도가 담배 매질부(220) 내의 다른 영역의 온도보다 높을 수 있다. 이에 따라, 다른 영역보다 중심 영역(1020)에 포함되는 에어로졸 생성 물질이 더 빠르게 고갈될 수 있다. That the aerosol-generating article is heated by heat transferred from the inside of the tobacco medium 220 may mean that the heater is arranged to be inserted into the tobacco medium 220 , as shown in FIG. 1 . In general, when the heater is inserted into the tobacco medium 220, the temperature of the central region 1020 of the tobacco medium 220 may be higher than the temperature of other regions in the tobacco medium 220. Accordingly, the aerosol generating material included in the central region 1020 may be depleted more rapidly than other regions.
예시적인 실시예에 따르면, 열전도성 분말(1010)은 담배 매질부(220)의 길이 방향 축(즉, 도 10의 단면도에 도시된 담배 매질부(220)의 중심)으로부터 멀어질수록 더 높은 밀도로 분포될 수 있다. 이에 따라, 에어로졸 생성 물품과 함께 사용되는 에어로졸 생성 장치가 내부 가열 방식의 히터를 포함하더라도, 담배 매질부(220)는 전체적으로 균일하게 가열될 수 있다. 예를 들어, 담배 매질부(220)의 다른 영역(즉, 중심 영역(1020)이 아닌 영역)에 포함되는 열전도성 분말(1010)의 양은 담배 매질부(220)의 중심 영역(1020)에 포함되는 열전도성 분말(1010)의 양보다 2배 이상 많을 수 있다. 다만, 이에 반드시 제한되는 것은 아니다. 한편, 중심 영역(1020)은 담배 매질부(220)의 직경의 절반에 해당하는 영역일 수 있으나, 이에 제한되는 것은 아니다.According to an exemplary embodiment, the thermally conductive powder 1010 has a higher density the further away from the longitudinal axis of the tobacco medium 220 (ie, the center of the tobacco medium 220 shown in the cross-sectional view of FIG. 10 ). can be distributed as Accordingly, even if the aerosol-generating device used with the aerosol-generating article includes a heater of an internal heating method, the tobacco medium 220 may be uniformly heated as a whole. For example, the amount of thermally conductive powder 1010 contained in another region of the tobacco medium 220 (ie, a region other than the central region 1020 ) is included in the central region 1020 of the tobacco medium 220 . It may be more than twice as much as the amount of the thermally conductive powder 1010 to be. However, the present invention is not necessarily limited thereto. Meanwhile, the central region 1020 may be a region corresponding to half the diameter of the tobacco medium 220 , but is not limited thereto.
다시 도 5로 돌아와서, 담배 매질부(220)에 포함되는 열전도성 분말의 분포는 도 9 및 도 10의 예시들에 반드시 제한되는 것은 아니다. 열전도성 분말은 담배 매질부(220)의 전체 영역에 대해 균일하게 분포할 수도 있다.
