Description

근래에 일반적인 궐련의 단점들을 극복하는 대체 방법에 관한 수요가 증가하고 있다. 예를 들어, 궐련을 연소시켜 에어로졸을 생성시키는 방법이 아닌 궐련 내의 에어로졸 발생 물질이 가열됨에 따라 에어로졸이 생성되는 방법에 관한 수요가 증가하고 있다.In recent years, there has been an increasing demand for alternative methods to overcome the disadvantages of regular cigarettes. For example, there is an increasing demand for a method in which aerosol is generated by heating the aerosol-generating material in the cigarette, rather than a method of generating aerosol by burning a cigarette.
일반적으로 담배 매질의 주원료인 슬러리 판상엽 시트의 경우 인장력이 약하여 제조적성이 어려우며, 담배 매질에 보습제도 다량 함유되어 있어 물리성이 취약하다. 또한, 글리세린 등과 같은 액상을 함유한 담배 매질은 친수성으로 인하여 주위 환경의 습도에도 민감하여 제조 공정 환경을 제어하는데 어려움이 있다. 담배 매질 내 함유시킬 수 있는 액상의 양도 한계가 있다.In general, slurry leaf sheets, which are the main raw material of the tobacco medium, have weak tensile strength and are difficult to manufacture, and the tobacco medium contains a large amount of humectants, making its physical properties weak. In addition, tobacco media containing liquids such as glycerin are sensitive to humidity in the surrounding environment due to their hydrophilic nature, making it difficult to control the manufacturing process environment. There is a limit to the amount of liquid that can be contained in the tobacco medium.
담배 매질을 포함하는 궐련 이외에 별도의 카토마이저에 액상을 보관하여 에어로졸을 추가로 발생시켜서 사용자가 궐련을 흡입할 때 액상으로부터 유래하는 에어로졸을 궐련을 통해 흡입하는 경우도 제안되고 있으나, 카토마이저에 함유된 액상을 관리하는데 어려움(유통기한, 변질 등)이 있으며, 카토마이저에서 생성된 에어로졸이 이동하는 기류 패스에 응축물이 발생하여 오염이 발생할 수 있다. In addition to cigarettes containing tobacco media, it has been proposed that the liquid is stored in a separate cartomizer to generate additional aerosol, so that when the user inhales the cigarette, the aerosol derived from the liquid is inhaled through the cigarette. However, it has been proposed that the liquid contained in the cartomizer is There are difficulties in managing the liquid (expiration date, deterioration, etc.), and condensation may occur in the airflow path through which the aerosol generated in the cartomizer moves, causing contamination.

In the drawings of the present disclosure, the sizes of certain components, particularly the porous grains 30a, are exaggerated for visibility, and the sizes of the components are not limited by their relative sizes in the drawings. In this embodiment, the aerosol medium aggregate 30 includes a plurality of porous particles 30a with micropores (indicated by A in FIG. 3) formed on the surface or inside. Additionally, the porous particles 30a accommodate an aerosol medium that generates an aerosol by heating.
다공성 알갱이(30a)는 에어로졸 매질 집합체(30)를 형성하는 단위 요소로서 특히 본 실시예에서는 버나드셀 현상을 이용하여 형성된다. 버나드 셀 현상에 의해 입자의 표면에 결함, 즉 마이크로 기공(A)이 유도되어 결과적으로 다공성 알갱이(30a)의 비표면적을 증가시킬 수 있고 그에 따라 에어로졸 매질의 흡습량 내지 수용량을 증가시킬 수 있으며, 최종적으로 에어로졸 매질 집합체(30)로부터 기인하는 에어로졸 발생량을 증가시킬 수 있다. The porous grains 30a are unit elements forming the aerosol medium aggregate 30, and in particular, in this embodiment, they are formed using the Bernard Cell phenomenon. Due to the Barnard cell phenomenon, defects, that is, micropores (A), are induced on the surface of the particles, which can consequently increase the specific surface area of the porous grains (30a) and thereby increase the moisture absorption or water capacity of the aerosol medium, Ultimately, the amount of aerosol generated from the aerosol medium aggregate 30 can be increased.
버나드셀 현상을 이용한, 표면이나 내부에 마이크로 기공이 형성된 복수의 다공성 알갱이(30a)의 예시적인 제조방법은, 금속 이온과 결합된 실리케이트 분말과 결합제를 제1 용매에 분산하여 제1 분산 용액을 제조하는 단계, 첨가제를 제2 용매에 분산시켜 교반하여 제2 분산 용액을 제조하는 단계, 제1 분산 용액과 제2 분산 용액을 혼합하고 교반하여 혼합 슬러리를 제조하는 단계 및 혼합 슬러리를 분무 건조하는 단계를 포함한다.An exemplary method of manufacturing a plurality of porous grains (30a) with micropores formed on the surface or inside using the Bernard Cell phenomenon is to prepare a first dispersion solution by dispersing silicate powder bonded to a metal ion and a binder in a first solvent. a step of preparing a second dispersion solution by dispersing and stirring the additive in a second solvent, preparing a mixed slurry by mixing and stirring the first dispersion solution and the second dispersion solution, and spray drying the mixed slurry. Includes.
이때, 금속 실리케이트 분말은 Mg, Al, Zr, Li, Ba, MgAl, Na 및 Ca 중에서 선택된 하나 이상의 금속 이온을 포함하는 것이 바람직하며, 금속 실리케이트 분말은 제1 용매 대비 5 내지 40 wt% 분산된다. At this time, the metal silicate powder preferably contains one or more metal ions selected from Mg, Al, Zr, Li, Ba, MgAl, Na, and Ca, and the metal silicate powder is dispersed in an amount of 5 to 40 wt% relative to the first solvent.
한편, 제1 분산 용액의 제조에 사용되는 결합제는 폴리비닐알콜, 폴리비닐 아세테이트, 폴리에틸렌, 폴리비닐부티렌, 폴리프로필렌, 폴리염화비닐, 폴리 아크릴, 폴리 아크릴 아미드, 구아 검, 젤라틴, 천연고무 중에서 선택된 하나 이상인 것이 바람직하다. Meanwhile, the binder used in the preparation of the first dispersion solution is selected from polyvinyl alcohol, polyvinyl acetate, polyethylene, polyvinylbutylene, polypropylene, polyvinyl chloride, polyacrylic, polyacrylamide, guar gum, gelatin, and natural rubber. It is desirable to have more than one selected.
또한 제1 용매는 물, 에탄올, 톨루엔, IPA, 아세톤 중에서 선택된 하나 이상을 포함하며, 제1 용매는 금속 실리케이트 중량 대비 70~220 wt% 사용되는 것이 바람직하다. In addition, the first solvent includes one or more selected from water, ethanol, toluene, IPA, and acetone, and it is preferable that the first solvent is used in an amount of 70 to 220 wt% based on the weight of the metal silicate.
이때, 제1 분산 용액의 제조에 사용되는 첨가제는 미네랄 스프릿 또는 자일렌과 같은 고비점 용제를 포함하는 것이 바람직하며, 금속 실리케이트 대비 0.5~10 wt% 첨가되는 것이 바람직하다. 첨가제에 따라 다르나 유기물 첨가제의 경우 10 wt% 이상이 될 경우 비드 형태를 유지하기 불가하고, 고점성을 유발하며, 작업성 저하될 수 있다. At this time, the additive used in the preparation of the first dispersion solution preferably includes a high boiling point solvent such as mineral spirits or xylene, and is preferably added in an amount of 0.5 to 10 wt% relative to the metal silicate. It varies depending on the additive, but in the case of organic additives, if the amount is more than 10 wt%, it may be impossible to maintain the bead shape, cause high viscosity, and reduce workability.
또한 제2 용액은 물, 에탄올, 톨루엔, IPA, 아세톤 중에서 선택된 하나 이상을 포함하며, 금속 실리케이트 대비 5 내지 30 wt% 포함되는 것이 바람직하다. Additionally, the second solution contains at least one selected from water, ethanol, toluene, IPA, and acetone, and is preferably contained in an amount of 5 to 30 wt% based on the metal silicate.
제1 분산 용액과 제2 분산 용액을 혼합하고 교반하여 혼합 슬러리를 제조한 다음 혼합 슬러리를 분무 건조하여 마이크로 기공이 형성된 다공성 알갱이를 형성한다. 이때, 분무 건조는 디스크 방식을 사용하며, 디스크의 회전 속도는 500 내지 9000 rpm의 범위 내에서 조절되는 것이 바람직하다. 디스크의 회전 속도는 500 rpm보다 작으면 원심력으로 인한 효과가 크지 않아 구형 입자의 크기가 지나치게 커진다. 반면, 회전 디스크의 회전 속도가 9000 rpm이 넘어가면 20㎛ 이하의 구형 입자들의 생성 비율이 높아지고, 이러한 소형 구형 입자들이 에어로졸 발생 장치의 히터 또는 액상 흡습체의 제조 시에 오히려 히터 또는 액상 흡습체의 표면 기공을 막아버려 오히려 비표면적을 감소시키는 단점이 있다. 따라서 디스크의 회전 속도는 500 내지 9000 rpm의 범위 내에서 조절되는 것이 바람직하다.The first dispersion solution and the second dispersion solution are mixed and stirred to prepare a mixed slurry, and then the mixed slurry is spray dried to form porous granules with micropores. At this time, spray drying uses a disk method, and the rotation speed of the disk is preferably adjusted within the range of 500 to 9000 rpm. If the rotation speed of the disk is less than 500 rpm, the effect due to centrifugal force is not significant, and the size of the spherical particles becomes excessively large. On the other hand, when the rotation speed of the rotating disk exceeds 9000 rpm, the generation rate of spherical particles of 20㎛ or less increases, and these small spherical particles rather form a part of the heater or liquid hygroscopic body when manufacturing the heater or liquid hygroscopic body of the aerosol generating device. It has the disadvantage of blocking surface pores and reducing the specific surface area. Therefore, it is desirable that the rotation speed of the disk is adjusted within the range of 500 to 9000 rpm.
혼합 슬러리가 분무되는 디스크는 220~300 ℃ 온도를 유지하는 챔버 내에서 회전하며, 분무 건조 단계에서 버나드셀 현상이 유발되어, 도 2의 사진과 같이 표면 결함(크랙)을 유발하여 다공성 알갱이의 비표면적을 증가시킬 수 있다. 이때, 마이크로 기공이 형성된 다공성 알갱이는 제조 과정에서 조공제를 별도로 첨가하지 않고도 마이크로 기공을 형성할 수 있다는 장점이 있다. 이렇게 제조된 마이크로 기공이 형성된 다공성 알갱이는 비표면적을 증가시킬 수 있다. 따라서 실시예에 따른 버나드 셀 현상을 이용한 마이크로 기공이 형성된 다공성 알갱이로 에어로졸 발생장치의 히터 또는 에어로졸 매질 흡습체를 제조할 경우, 에어로졸 매질을 흡습할 수 있는 흡습량 내지 수용량이 증가하고, 그에 따라 에어로졸 매질을 기화시켜 발생할 수 있는 무화량을 증가시킬 수 있다는 장점이 있다. The disk on which the mixed slurry is sprayed rotates in a chamber maintaining a temperature of 220 to 300 ℃, and the Bernard Cell phenomenon is induced during the spray drying stage, causing surface defects (cracks) as shown in the photo in Figure 2, increasing the ratio of porous grains. Surface area can be increased. At this time, porous grains with micro pores have the advantage of being able to form micro pores without adding a separate pore-forming agent during the manufacturing process. The porous granules with micropores produced in this way can increase the specific surface area. Therefore, when a heater of an aerosol generating device or an aerosol medium moisture absorber is manufactured from porous granules in which micropores are formed using the Barnard cell phenomenon according to the embodiment, the moisture absorption or capacity capable of absorbing the aerosol medium increases, and accordingly the aerosol It has the advantage of being able to increase the amount of atomization that can occur by vaporizing the medium.

The porous grains 30a may be in the form of beads or spherical powder. The diameter or size of the porous particles 30a is a size capable of securing a specific surface area to effectively absorb the aerosol medium, and preferably falls within the range of 10 ㎛ to 300 ㎛.

The pores between the plurality of porous particles 30a included in the aerosol medium aggregate 30 correspond to macro pores (indicated by B in FIG. 1) and range from 1 ㎛ to 130 ㎛, more preferably 1 ㎛. It falls in the range of ~20 ㎛. For example, the aerosol medium assembly 30 may be an aggregate of a plurality of porous particles 30a charged into a predetermined space and containing the aerosol medium. At this time, the gaps formed between the plurality of porous grains 30a charged in the predetermined space may become macro pores B. Preferably, the porosity of the aerosol medium aggregate 30 is in the range of 30% to 70%. Here, porosity can be calculated as the total of macro pores (B) and micro pores (A).

Additionally, the porous grains 30a may additionally include fiber glass. These fiber glasses contain SiO2 in weight percent of more than 50%.
실시예에서 복수의 다공성 알갱이(30a)는 에어로졸 매질을 흡습 내지 수용하는 기능 및/또는, 에어로졸 발생 장치나 카트리지에 장착되어, 액상화된 에어로졸 매질을 모세관 현상에 의해 이송시키는 기능을 지닌다. 이러한 흡습 기능과 이송 기능은 실시예와 같은 마이크로 기공과 매크로 기공을 포함하는 다공성 알갱이들(30a)로 구성된 에어로졸 매질 집합체(30)에서 보다 원활하게 수행될 수 있다. 이러한 흡습 기능과 이송 기능에 의해서, 에어로졸 발생 장치나 카트리지에 적용될 경우, 사용자에 의한 퍼프 시에 일정한 에어로졸 매질의 이송이 가능함으로써 일정한 양의 연무가 발생되도록 할 수 있다.In the embodiment, the plurality of porous particles 30a have the function of absorbing or receiving the aerosol medium and/or are mounted on an aerosol generating device or cartridge and have the function of transporting the liquefied aerosol medium by capillary action. These moisture absorption and transport functions can be performed more smoothly in the aerosol medium aggregate 30 composed of porous particles 30a containing micro-pores and macro-pores as in the embodiment. Due to these moisture absorption and transfer functions, when applied to an aerosol generating device or cartridge, it is possible to transfer a certain amount of aerosol medium when a user puffs, thereby generating a certain amount of mist.
실시예들에 있어서, 에어로졸 매질 집합체(30)가 포함하는 복수의 다공성 알갱이(30a)는 소정의 바인더를 이용하여 입체 형상으로 블록화될 수 있다. 또는 이러한 블록화 과정 없이, 복수의 비드 형태나 구형 분말 형태의 다공성 알갱이(30a)를 소정 공간에 충진시키는 방법으로 에어로졸 발생 장치나 카트리지에 무화기로 적용할 수 있다. 다공성 알갱이(30a)를 에어로졸 매질을 수용한 상태로 에어로졸 발생 장치나 카트리지에 장입하고, 히터가 이를 가열할 수 있도록 배치할 수 있다. 이 때 히터의 형태는 블레이드 형태나 원통형, 핀형 등 다양한 형태를 가질 수 있다. 에어로졸 매질 집합체(30)는 특정한 형상을 가지지 않기 때문에, 히터의 형태나 배치가 자유롭고, 히터와 에어로졸 매질 집합체(30)의 접촉면적을 넓힐 수 있다는 장점이 있다. 또한 제조 단계에 있어서, 에어로졸 매질을 다공성 알갱이(30a)에 수용시킬 때, 복수의 다공성 알갱이(30a) 자체를 액상의 에어로졸 매질에 담그거나 그와 혼합시키는 방법으로 빠르고 용이하게 에어로졸 매질을 흡습시켜 수용할 수 있다.In embodiments, the plurality of porous particles 30a included in the aerosol medium aggregate 30 may be block into a three-dimensional shape using a predetermined binder. Alternatively, without this blocking process, the atomizer can be applied to an aerosol generating device or cartridge by filling a predetermined space with a plurality of porous particles 30a in the form of beads or spherical powder. The porous particles 30a can be charged into an aerosol generating device or cartridge while accommodating the aerosol medium, and arranged so that a heater can heat it. At this time, the shape of the heater may have various shapes such as a blade shape, a cylindrical shape, or a fin shape. Since the aerosol medium assembly 30 does not have a specific shape, the shape or arrangement of the heater is free, and the contact area between the heater and the aerosol medium assembly 30 can be expanded. In addition, in the manufacturing step, when the aerosol medium is accommodated in the porous grains (30a), the plurality of porous grains (30a) themselves are immersed in or mixed with the liquid aerosol medium to quickly and easily absorb and accommodate the aerosol medium. can do.
결국 에어로졸 매질 집합체(30)가 포함하는 마이크로 기공(A)과 매크로 기공(B)에 에어로졸 매질이 효과적으로 수용될 수 있어, 제조가 용이해짐과 동시에 에어로졸 발생의 효율이 증가할 수 있다.Ultimately, the aerosol medium can be effectively accommodated in the micro pores (A) and macro pores (B) included in the aerosol medium assembly 30, making manufacturing easier and increasing the efficiency of aerosol generation.
실시예에 따라 에어로졸 매질 집합체(30)는 랩핑 페이퍼(31)에 의해 랩핑되어 실린더 형상의 에어로졸 매질 로드로 형성될 수 있다. 이 때 랩핑 페이퍼(31)는 다공성 알갱이(30a)가 충진되는 충진 공간을 실질적으로 정의하며, 적어도 에어로졸 매질 집합체(30)의 측면을 랩핑하여 다공성 알갱이(30a)가 에어로졸 매질 집합체(30)로부터 탈락하는 것을 방지할 수 있다. 바람직하게 랩핑 페이퍼(31)는 에어로졸 매질의 누액을 방지하기 위해 방수 코팅이 되어 있는 페이퍼나 멤브레인 재질로 이루어진다. 예를 들어, 랩핑 페이퍼(31)는 알루미늄 포일이 종이에 부착되어 형성된 합지로 제공될 수 있으며, 알루미늄 포일이 에어로졸 매질 집합체(30)에 접촉하도록 실린더 형상으로 랩핑된다. 이에 따라 알루미늄 포일은 에어로졸 매질 집합체(30)로부터 에어로졸 매질이 액화되어 에어로졸 매질 로드의 측면을 통해 흘러나올 가능성을 없애거나 최소화할 수 있다.Depending on the embodiment, the aerosol medium assembly 30 may be wrapped by wrapping paper 31 to form a cylindrical aerosol medium rod. At this time, the wrapping paper 31 substantially defines the filling space in which the porous particles 30a are filled, and wraps at least the side of the aerosol medium assembly 30 to prevent the porous particles 30a from falling off from the aerosol medium assembly 30. You can prevent it from happening. Preferably, the wrapping paper 31 is made of paper or membrane material with a waterproof coating to prevent leakage of the aerosol medium. For example, the wrapping paper 31 may be provided as a laminate formed by attaching aluminum foil to paper, and the aluminum foil is wrapped in a cylindrical shape so that it contacts the aerosol medium assembly 30. Accordingly, the aluminum foil can eliminate or minimize the possibility of the aerosol medium being liquefied from the aerosol medium assembly 30 and flowing out through the side of the aerosol medium rod.
에어로졸 매질 집합체(30)로부터 다공성 알갱이(30a)의 이탈을 방지하기 위하여, 소정의 바인더가 적용될 수 있으며, 또는 에어로졸 매질 로드의 형성 시, 랩핑 페이퍼(31)로 에어로졸 매질 집합체(30)의 측면뿐만이 아닌, 전체 방향을 감쌀 수도 있다. 다만 이 경우의 랩핑 페이퍼(31)는 에어로졸 입자는 통과시킬 수 있을 정도의 기공을 갖고 있는 것이 바람직하다.In order to prevent the porous particles 30a from leaving the aerosol medium assembly 30, a predetermined binder may be applied, or when forming the aerosol medium rod, only the side of the aerosol medium assembly 30 is covered with the wrapping paper 31. No, it can cover the entire direction. However, in this case, it is preferable that the wrapping paper 31 has pores large enough to allow aerosol particles to pass through.
도 1을 참조하면, 예를 들어, 에어로졸 매질 로드 형태의 에어로졸 매질 집합체(30)가 에어로졸 발생 장치 내에 삽입되어, 히터에 의해 특히 그 측면, 즉 랩핑 페이퍼(31)로 둘러쌓인 부분이 가열되면, 이 열은 다공성 알갱이(30a)에 수용되어 있는 에어로졸 매질을 가열하여, 궁극적으로는 에어로졸이 생성될 수 있다. 도 1과 같이 에어로졸 매질 집합체(30)가 랩핑 페이퍼(31)에 의해 그 측면이 둘러쌓여 에어로졸 매질 로드를 형성하는 경우, 사용자는 흡입 행위를 통하여, 화살표로 도시한, 하단에서 상단으로 향하는 공기 흐름을 발생시켜 에어로졸 매질로부터 기인하는 에어로졸을 흡입할 수 있다. 이와 같은 에어로졸 매질 집합체(30)의 사용에 있어 하단에서 상단으로 향하는 공기 흐름을 가정하면, 편의상 하단쪽을 “상류”로 참조할 수 있으며 상단쪽을 “하류”로 참조할 수 있다.Referring to Figure 1, for example, when an aerosol medium assembly 30 in the form of an aerosol medium rod is inserted into an aerosol generating device and heated by a heater, especially its side, i.e. the part surrounded by the wrapping paper 31, This heat heats the aerosol medium contained in the porous particles 30a, ultimately producing an aerosol. As shown in FIG. 1, when the aerosol medium aggregate 30 is surrounded on its side by the wrapping paper 31 to form an aerosol medium rod, the user creates an air flow from the bottom to the top, as shown by the arrow, through the act of inhalation. It is possible to inhale aerosols originating from an aerosol medium. In the use of such aerosol medium aggregate 30, assuming an air flow from the bottom to the top, for convenience, the bottom side can be referred to as “upstream” and the top side can be referred to as “downstream.”
실시예에서, 에어로졸 매질은 가열에 의해 에어로졸로 변환될 수 있는 소재, 예를 들어, 향료, 니코틴, VG(식물성 글리세린), PG(프로필렌 글리콜), 약품, 정향 등 중의 어느 하나 이상의 물질을 포함할 수 있다. 특히 에어로졸 매질에 VG(식물성 글리세린), PG(프로필렌 글리콜)이 포함될 경우, 풍부한 에어로졸 및 시각 효과(연기)가 발생할 수 있다는 점에서 바람직하다.In an embodiment, the aerosol medium may include any one or more of materials that can be converted to an aerosol by heating, such as flavoring, nicotine, VG (vegetable glycerin), PG (propylene glycol), medicine, clove, etc. You can. In particular, when VG (vegetable glycerin) and PG (propylene glycol) are included in the aerosol medium, it is desirable because abundant aerosol and visual effects (smoke) can be generated.
에어로졸 매질 집합체에 포함되는 에어로졸 매질은 상온에서 액상이거나 겔상이거나 또는 고형화상일 수 있다. 예를 들어, 상온에서 액상인 VG와 PG를 혼합하여 액상 에어로졸 매질을 만들 수 있다. 에어로졸 매질은 상온에서 액상임에도 불구하고, 그 흡습량을 조절하면, 에어로졸 매질 집합체(30)에 포함된 마이크로 기공(A)과 매크로 기공(B)에 흡습된 채로 누액의 발생 없이 유지될 수 있다.The aerosol medium included in the aerosol medium aggregate may be liquid, gel, or solid at room temperature. For example, a liquid aerosol medium can be created by mixing liquid VG and PG at room temperature. Although the aerosol medium is liquid at room temperature, if its moisture absorption amount is controlled, it can be maintained without leakage while being absorbed into the micro pores (A) and macro pores (B) included in the aerosol medium assembly 30.
또한 예를 들어, 겔상 에어로졸 매질은 적어도 글리세린과 증점제를 혼합하여 형성할 수 있다. 일례로 글리세린 PG(Proplylene Glycol) 혹은 VG(Vegetable Glycerine), 혹은 PG 및 VG 혼합물을 열을 주며 30분간 교반하여 점도를 낮추고, 여기에 겔화할 수 있는 첨가물인 증점제(카라기난 등)를 10 ~ 50 중량%를 첨가하여 첨가물이 글리세린에 녹을 때까지 교반하고 글리세린과 증점제 혼합물을 얻을 수 있게 된다. 혼합물은 상온을 포함하는 제1 온도 범위(예를 들어 50 ℃ 미만의 온도 범위)에서는 겔상 혹은 반고상을 유지하며, 가열되어 제1 온도 범위보다 높은 제2 온도 범위(예를 들어 50 - 100 ℃의 온도 범위)에서는 액상 내지 졸(sol)상으로 변화하여 액상으로 존재하고 추가로 가열되는 경우, 제2 온도 범위보다 높은 제3 온도 범위(예를 들어 150 ℃ 이상의 온도 범위)에서 에어로졸로 기화할 수 있다.Also, for example, a gel-like aerosol medium can be formed by mixing at least glycerin and a thickener. For example, glycerin PG (Proplylene Glycol) or VG (Vegetable Glycerine), or a mixture of PG and VG, is heated and stirred for 30 minutes to lower the viscosity, and then 10 to 50 weight of a thickener (carrageenan, etc.) that can gel is added. Add % and stir until the additive is dissolved in glycerin to obtain a glycerin and thickener mixture. The mixture maintains a gel or semi-solid state in a first temperature range that includes room temperature (e.g., a temperature range of less than 50° C.), and is heated to a second temperature range that is higher than the first temperature range (e.g., 50-100° C. temperature range), it changes from a liquid phase to a sol phase and exists in the liquid phase, and when further heated, it vaporizes into an aerosol in a third temperature range higher than the second temperature range (for example, a temperature range of 150 ℃ or higher). You can.
이상과 같이, 겔상 에어로졸 매질은, 한천(agar), 증점제, 전분 분말, 셀룰로오스류, 카르복시메틸에테르류, 천연 식품 향료 또는 과일 추출물 중 하나 이상을 추가적으로 포함할 수 있다. 아울러, 겔상 에어로졸 매질에서 글리세린의 함량은 50 중량% 이상인 것이 바람직하다. 또한, 혼합물은 추가로 한천(agar)를 포함할 수 있으며, 이 경우에 겔상 에어로졸 매질 혼합물을 형성하는데 유리하게 작용한다. 이에 부가하여, 겔상 에어로졸 매질 혼합물은 첨가물로 증점제, 전분 분말, 셀룰로오스류, 카르복시메틸에테르류를 포함할 수 있다.As described above, the gel-like aerosol medium may additionally include one or more of agar, thickener, starch powder, cellulose, carboxymethyl ether, natural food flavoring, or fruit extract. In addition, the content of glycerin in the gel-like aerosol medium is preferably 50% by weight or more. Additionally, the mixture may additionally contain agar, in which case it serves advantageously to form a gel-like aerosol medium mixture. In addition, the gel-like aerosol medium mixture may include thickeners, starch powder, cellulose, and carboxymethyl ether as additives.
예를 들어, 겔상 에어로졸 매질이 증점제 역할을 하는 것으로 널리 알려진 카라기난을 포함하는 것으로 상기와 같은 온도 범위에 따른 상 변화를 기대할 수 있다. 상온을 포함하는 제1 온도 범위에서 겔 상태의 에어로졸 매질은 제2 온도 범위에서 콜로이드 입자들의 연결이 해제되며 액상 내지 졸 상태로 변화할 수 있으며, 더욱 가열되어 제3 온도 범위에서 에어로졸로 기화될 수 있다.For example, since the gel-like aerosol medium contains carrageenan, which is widely known to act as a thickener, phase changes can be expected depending on the temperature range as described above. The aerosol medium in a gel state in a first temperature range including room temperature may change into a liquid or sol state as the colloidal particles are disconnected in a second temperature range, and may be further heated to vaporize into an aerosol in a third temperature range. there is.
실시예에 따라 겔상 에어로졸 매질은 0.1 내지 5 % 겔화제와, 글리세린을 포함하는 5 내지 100 %의 에어로졸 생성제와, 0.1 내지 20 %의 산미조절제와, 선택적으로 0.1 내지 15 %의 향미제, 첨가제 또는 활성 물질을 포함할 수 있다. 또한, 실시예에 따라 겔상 에어로졸 매질은 카파 카라기난, 아이오타 카라기난, 한천, 펙틴, 구아검, 젖산 칼슘, 염화 칼륨, 포도당, 전분 분말, 천연 식품 첨가제 또는 과일 추출물 또는 화합물 중 하나 이상을 추가적으로 포함할 수 있다. Depending on the embodiment, the gel-like aerosol medium may contain 0.1 to 5% of a gelling agent, 5 to 100% of an aerosol generator including glycerin, 0.1 to 20% of an acidity regulator, and optionally 0.1 to 15% of a flavoring agent and additives. Or it may contain an active substance. In addition, depending on the embodiment, the gel-like aerosol medium may additionally include one or more of kappa carrageenan, iota carrageenan, agar, pectin, guar gum, calcium lactate, potassium chloride, glucose, starch powder, natural food additives, or fruit extracts or compounds. You can.
앞서 설명한 바와 같이, 겔상의 에어로졸 매질은 제2 온도 범위보다 높은 예를 들어, 약 150 내지 300 ℃의 온도범위(제3 온도 범위)에서 기화하여 에어로졸화되는데, 가열 후 에어로졸화되어 흡입되지 않은 액상 상태의 에어로졸 매질은 상온으로 냉각되면 에어로졸 매질 집합체(30) 내부에서 다시 겔상으로 변할 수 있다.As described above, the gel-like aerosol medium is vaporized and aerosolized at a temperature range (third temperature range) higher than the second temperature range, for example, about 150 to 300° C., and is aerosolized after heating into a liquid phase that is not inhaled. When the aerosol medium is cooled to room temperature, it can change back into a gel state inside the aerosol medium assembly 30.
전술한 대로, 제 1 온도 범위에서 에어로졸 매질이 겔상 또는 반고상을 유지하도록, 에어로졸 매질은 증점제를 포함하는데, 바람직한 실시예에 따라 증점제는 글리세린을 포함하는 에어로졸 매질이 기화하여 에어로졸화되는 약 150 내지 300 ℃의 온도범위(제3 온도 범위)에서 기화하지 않고 다공성 알갱이(30a) 내지 에어로졸 매질 집합체(30)에 잔류한다. 즉 증점제는 주된 에어로졸 매질인 글리세린이 에어로졸로 기화할 때, 기화하지 않고 다공성 알갱이(30a) 내의 마이크로 기공(A)이나 다공성 알갱이(30a)들 사이의 매크로 기공(B)에 그대로 잔류한다. As described above, the aerosol medium includes a thickener so that the aerosol medium maintains a gel or semi-solid state in the first temperature range, and according to a preferred embodiment, the thickener is added at a temperature of about 150 to about 150° C. at which the aerosol medium containing glycerin is vaporized and aerosolized. It does not vaporize in the temperature range of 300°C (third temperature range) and remains in the porous particles 30a or the aerosol medium aggregate 30. That is, when glycerin, the main aerosol medium, vaporizes into an aerosol, the thickener does not vaporize but remains in the micropores (A) within the porous grains (30a) or the macropores (B) between the porous grains (30a).

This thickener is composed of one or more substances selected from the group including monosaccharides, disaccharides, sugar alcohols, and oligosaccharides. Methods such as using gelatin extracted from fish, meat, etc. or vegetable gelatin as a thickener to gelatinize glycerin, or mixing such gelatin thickener and water with glycerin and cooling while stirring were considered. However, the vaporization point of glycerin in the gel-like aerosol medium obtained in this way is It is approximately 200 to 300 ° C. under atmospheric pressure, and the vaporization point of water is approximately 100 ° C. under atmospheric pressure, so this gelatin or water thickener is in the temperature range of about 150 to 300 ° C.

Accordingly, the inventors considered other thickeners, and in the examples, the thickener includes one or more substances selected from the group including monosaccharides, disaccharides, sugar alcohols, and oligosaccharides.
바람직한 일 실시예에서, 단당류는 식물 추출물로 글루코스, 과당, 갈락토스를 포함하는 군으로부터 선택된 하나 이상의 물질을 포함한다. 글루코스의 기화점은 대기압하에서 527.1 ± 50.0 ℃이고, 과당의 기화점은 대기압하에서 697.1 ± 50.0 ℃이고, 갈락토스의 기화점은 대기압하에서 527.1 ± 50.0 ℃이므로, 글리세린을 포함하는 에어로졸 매질이 기화하여 에어로졸화되는 약 150 내지 300℃의 온도범위(제3 온도 범위)에서 기화하지 않고 흡습체 내에 그대로 잔류한다.In a preferred embodiment, the monosaccharide is a plant extract and includes one or more substances selected from the group comprising glucose, fructose, and galactose.

It does not vaporize in the temperature range of about 150 to 300°C (third temperature range) and remains in the moisture absorbent.
바람직한 다른 실시예에서, 이당류는 설탕 등에서 추출한 성분을 포함한다. 설탕의 기화점은 대기압하에서 697.1 ± 50.0 ℃이므로, 글리세린을 포함하는 에어로졸 매질이 기화하여 에어로졸화되는 약 150 내지 300℃의 온도범위(제3 온도 범위)에서 기화하지 않고 흡습체 내에 그대로 잔류한다.In another preferred embodiment, the disaccharide includes components derived from sugar, etc. Since the vaporization point of sugar is 697.1 ± 50.0 ° C. under atmospheric pressure, it does not vaporize in the temperature range of about 150 to 300 ° C. (third temperature range), at which the aerosol medium containing glycerin vaporizes and becomes aerosol, but remains in the absorbent.
바람직한 다른 실시예에서, 당알코올은 이소말트, 말티톨, 자일리톨, 소르비톨을 포함하는 군에서 선택된 하나 이상의 물질을 포함한다. 이소말트의 기화점은 788.5 ℃이고, 말티톨의 기화점은 대기압하에서 788.5 ± 60.0 ℃이므로, 글리세린을 포함하는 에어로졸 매질이 기화하여 에어로졸화되는 약 150 내지 300℃의 온도범위(제3 온도 범위)에서 기화하지 않고 흡습체 내에 그대로 잔류한다.In another preferred embodiment, the sugar alcohol includes one or more substances selected from the group including isomalt, maltitol, xylitol, and sorbitol. The vaporization point of isomalt is 788.5 ℃, and the vaporization point of maltitol is 788.5 ± 60.0 ℃ under atmospheric pressure, so in the temperature range of about 150 to 300 ℃ (third temperature range) where the aerosol medium containing glycerin vaporizes and becomes aerosol. It does not evaporate and remains in the absorbent.
바람직한 다른 실시예에서, 소당류는 이당류 이상의 당류로서, 말토덱스트린을 포함한다. 말소텍스트린의 기화점은 527.1 ℃이므로, 글리세린을 포함하는 에어로졸 매질이 기화하여 에어로졸화되는 약 150 내지 300℃의 온도범위(제3 온도 범위)에서 기화하지 않고 흡습체 내에 그대로 잔류한다.In another preferred embodiment, the monosaccharide is a disaccharide or higher saccharide and includes maltodextrin. Since the vaporization point of erase textrin is 527.1°C, it does not vaporize in the temperature range of about 150 to 300°C (third temperature range), where the aerosol medium containing glycerin vaporizes and becomes aerosol, but remains in the absorbent.
다음으로, 고형화상 에어로졸 매질 역시 겔상 에어로졸 매질과 유사하게, 글리세린과 증점제의 혼합물일 수 있다. 일례로 글리세린 PG(Proplylene Glycol) 혹은 VG(Vegetable Glycerine), 혹은 PG 및 VG 혼합물에, 고형화를 위한 첨가물인 증점제와, 고형화를 임시적으로 막기 위한 첨가물인 용해제를 넣은 혼합 용액을 만들 수 있다. 다음으로 이 혼합 용액을 가열하여 용해제만을 증발시키면 PG 및 VG는 증점제에 갇히며 고형화된 에어로졸 매질이 형성될 수 있다.Next, the solid aerosol medium may also be a mixture of glycerin and a thickener, similar to the gel aerosol medium. For example, a mixed solution can be made by adding a thickener, an additive for solidification, and a solubilizer, an additive to temporarily prevent solidification, to glycerin PG (Proplylene Glycol) or VG (Vegetable Glycerine), or a mixture of PG and VG. Next, when this mixed solution is heated to evaporate only the solvent, PG and VG are trapped in the thickener and a solidified aerosol medium can be formed.
이 때, 고형화를 위해 사용되는 증점제는 셀룰로오스 유도체(Cellulose derivatives), 덱스트린 유도체(Dextrin derivatives), 알지네이트 유도체(Alginate derivatives), 검(Gum), 펙틴(Pectin), 헤미셀룰로오스 유도체(Hemicellulose derivatices) 및 젤라틴(Gelatin)을 포함하는 군에서 선택된 하나 이상의 물질을 포함하는 것이 바람직하다. 또한 용해제는 예를 들어 증류수이거나 에탄올일 수 있는데, 특히 사용될 에어로졸 매질(예를 들어 PG와 VG) 및 증점제보다 끓는 점이 낮은 물질인 것이 바람직하다.At this time, the thickeners used for solidification include cellulose derivatives, dextrin derivatives, alginate derivatives, gum, pectin, hemicellulose derivatives, and gelatin ( It is preferable to include one or more substances selected from the group containing gelatin. The solubilizing agent may also be, for example, distilled water or ethanol; it is particularly preferred that it is a substance with a lower boiling point than the aerosol medium to be used (e.g. PG and VG) and the thickening agent.
상기와 같은 바람직한 실시예를 따를 경우, 액상의 에어로졸 매질(예를 들어 PG 또는 VG), 증점제 및 용해제의 혼합 용액을 제조한 뒤, 이를 전술한 복수의 다공성 알갱이(30a)와 혼합하여 다공성 알갱이(30a)에 흡습시킨 후, 가열하여 다공성 알갱이(30a)에 흡습된 혼합 용액에 포함된, 끓는 점이 상대적으로 낮은, 용해제만을 증발시키고, 에어로졸 매질과 증점제는 다공성 알갱이(30a)에 잔존시킬 수 있다. 이 때 PG 및 VG는 증점제에 갇히며 고형화상의 에어로졸 매질이 형성되고, 궁극적으로는 고형화상 에어로졸 매질을 포함하는 에어로졸 매질 집합체(30)가 제조될 수 있다.When following the preferred embodiment as described above, a mixed solution of a liquid aerosol medium (for example, PG or VG), a thickener, and a solubilizer is prepared, and then mixed with the plurality of porous granules 30a described above to form porous granules ( After moisture absorption in 30a), it is heated to evaporate only the solvent with a relatively low boiling point contained in the mixed solution absorbed in the porous grains (30a), and the aerosol medium and thickener can remain in the porous grains (30a). At this time, PG and VG are trapped in the thickener, forming a solid aerosol medium, and ultimately, an aerosol medium aggregate 30 containing the solid aerosol medium can be produced.
또한 상기 바람직한 실시예에 따른 에어로졸 매질 집합체(30)의 고형화상 에어로졸 매질은, 전술한 겔상 에어로졸 매질과 마찬가지로 온도 변화에 따른 상 변화를 기대할 수 있다. 즉 고형화상 에어로졸 매질은 상온 내지 상온을 포함하는 소정의 온도 범위(예를 들어 50 ℃ 미만의 온도 범위, 제1 온도 범위)에서 증점제의 작용에 의하여 고형화상으로 존재한다. 또한 에어로졸 매질 집합체(30)의 통상적인 사용 양태에 있어서, 에어로졸 매질 집합체(30)는 에어로졸 발생 장치 내의 히터에 의해 가열되어, 제1 온도 범위보다 높은 제2 온도 범위(예를 들어 50 - 100 ℃의 온도 범위)에서 증점제는 점점 그 성질을 잃어, 고형화상 에어로졸 매질은 액상으로 변화할 수 있으며, 제2 온도 범위보다 높은 제3 온도 범위(예를 들어 150 ℃ 내지 300 ℃의 온도 범위)에서, 에어로졸 매질(예를 들어 PG 및 VG)은 기화될 수 있다. 이 때 예를 들어, 제2 온도 범위에서 에어로졸 매질은 액상화에도 불구하고, 에어로졸 매질 집합체(30)가 포함하는 마이크로 기공(A)과 매크로 기공(B) 내에 여전히 흡습 내지 수용되어 있으므로, 누액이 발생할 가능성은 거의 없다.In addition, the solid image aerosol medium of the aerosol medium assembly 30 according to the preferred embodiment can be expected to change phase according to temperature changes, similar to the gel-like aerosol medium described above. That is, the solid image aerosol medium exists in a solid image due to the action of the thickener in a predetermined temperature range including room temperature to room temperature (for example, a temperature range below 50° C., a first temperature range). Also, in a typical use of the aerosol medium assembly 30, the aerosol medium assembly 30 is heated by a heater in the aerosol generating device to a second temperature range higher than the first temperature range (e.g., 50 - 100° C. temperature range), the thickener gradually loses its properties, and the solid phase aerosol medium can change to a liquid phase, and in a third temperature range higher than the second temperature range (e.g., a temperature range of 150° C. to 300° C.), Aerosol media (eg PG and VG) can be vaporized. At this time, for example, in the second temperature range, despite being liquefied, the aerosol medium is still absorbed or contained within the micropores (A) and macropores (B) included in the aerosol medium assembly 30, so leakage may occur. Very unlikely.
또한 상기 바람직한 실시예에 따를 경우, 증점제는 글리세린을 포함하는 에어로졸 매질이 기화하여 에어로졸화되는 약 150 ℃ 내지 300 ℃의 온도범위(제3 온도 범위)에서 기화하지 않고 다공성 알갱이(30a) 내지 에어로졸 매질 집합체(30)에 잔류한다. 즉 증점제는 주된 에어로졸 매질인 글리세린이 에어로졸로 기화할 때, 기화하지 않고 다공성 알갱이(30a) 내의 마이크로 기공(A)이나 다공성 알갱이(30a)들 사이의 매크로 기공(B)에 그대로 잔류한다. 따라서 사용자는 일반적인 사용 양태에 있어서 예를 들어 PG나 VG와 같은 기화된 에어로졸 매질만을 흡입하며, 증점제는 흡입하지 않을 수 있다.In addition, according to the preferred embodiment, the thickener does not vaporize in the temperature range of about 150 ° C to 300 ° C (third temperature range), where the aerosol medium containing glycerin is vaporized and aerosolized, but is formed in the porous particles 30a to the aerosol medium. It remains in the aggregate 30. That is, when glycerin, the main aerosol medium, vaporizes into an aerosol, the thickener does not vaporize but remains in the micropores (A) within the porous grains (30a) or the macropores (B) between the porous grains (30a). Therefore, in general usage, the user may inhale only the vaporized aerosol medium, such as PG or VG, and not the thickener.
에어로졸 매질은 추가로 천연 식품 향료 또는 과일 추출물을 포함할 수 있다. 이 경우 발생한 에어로졸을 통해 사용자에게 다양한 맛을 가미하는 것이 가능해진다. 어느 경우든 에어로졸 매질 혼합물에서 글리세린의 함량은 50 중량% 이상인 것이 바람직한데, 이렇게 함으로써 발생한 에어로졸에서 탄맛을 최소화할 수 있게 된다. 추가적으로 에어로졸 매질 혼합물은 니코틴을 포함할 수도 있고, 포함하지 않을 수도 있다.The aerosol medium may additionally contain natural food flavors or fruit extracts. In this case, it becomes possible to add various flavors to the user through the generated aerosol. In any case, it is preferable that the glycerin content in the aerosol medium mixture is 50% by weight or more, thereby minimizing the burnt taste in the generated aerosol. Additionally, the aerosol medium mixture may or may not contain nicotine.
에어로졸 매질은 추가로 향미제를 포함할 수 있으며, 예를 들어, 향미제는 감초, 자당, 과당 시럽, 이소감미제, 코코아, 라벤더, 시나몬, 카르다몸, 셀러리, 호로파, 카스카릴라, 백단, 베르가못, 제라늄, 벌꿀 에센스, 장미 오일, 바닐라, 레몬 오일, 오렌지 오일, 민트 오일, 계피, 캐러웨이, 코냑, 자스민, 카모마일, 멘톨, 계피, 일랑일랑, 샐비어, 스피어민트, 생강, 고수 또는 커피 등을 포함할 수 있다.The aerosol medium may further include flavoring agents, for example, licorice, sucrose, fructose syrup, iso-sweeteners, cocoa, lavender, cinnamon, cardamom, celery, fenugreek, cascarilla, sandalwood, Bergamot, geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, mint oil, cinnamon, caraway, cognac, jasmine, chamomile, menthol, cinnamon, ylang ylang, sage, spearmint, ginger, coriander or coffee. It can be included.
도 4는 본 발명의 일 실시예에 따른, 액상 또는 겔상의 에어로졸 매질을 포함하는 에어로졸 매질 집합체(30)의 제조 방법을 나타낸 순서도, 도 5는 도 4의 제조 방법을 이해하기 쉽게 표현한 개념도이다. 먼저, 용액 준비 단계(s110)로서 용기(K)에 액상의 에어로졸 매질(예를 들어, PG와 VG 혼합물) 혼합 용액(M)을 준비한다(도 5의 (a)). 겔상 에어로졸 매질의 경우, 상기 혼합 용액(M)은 증점제를 더욱 포함할 수 있으며, 겔상화를 방지하기 위하여 상기 혼합 용액(M)은 소정 온도(예를 들어 전술한 제2 온도 범위)로 가열된 상태일 수 있다.Figure 4 is a flowchart showing a method of manufacturing an aerosol medium aggregate 30 containing a liquid or gel-like aerosol medium according to an embodiment of the present invention, and Figure 5 is a conceptual diagram expressing the manufacturing method of Figure 4 in an easy-to-understand manner. First, as a solution preparation step (s110), a liquid aerosol medium (e.g., PG and VG mixture) mixed solution (M) is prepared in the container (K) (FIG. 5(a)). In the case of a gel-like aerosol medium, the mixed solution (M) may further include a thickener, and in order to prevent gelation, the mixed solution (M) is heated to a predetermined temperature (for example, the second temperature range described above). It may be a state.
다음으로 흡습 단계(s120)로서, 다공성 알갱이(30a)들을 용기(K)로 도입하여 상기 혼합 용액(M)에 적신다(도 5의 (b), (c)). 예를 들어 이 때 다공성 알갱이(30a)가 잘 적셔지도록 교반 작업이 수행될 수 있다. 그로 인하여, 다공성 알갱이(30a)와 혼합 용액(M)이 혼합되며 다공성 알갱이(30a)의 마이크로 기공 및 표면에 상기 혼합 용액(M)이 흡습 내지 수용될 수 있다. Next, in the moisture absorption step (s120), the porous granules (30a) are introduced into the container (K) and soaked in the mixed solution (M) (FIG. 5 (b), (c)). For example, at this time, stirring may be performed to ensure that the porous grains 30a are well wetted. As a result, the porous grains (30a) and the mixed solution (M) are mixed, and the mixed solution (M) can absorb moisture or be accommodated in the micropores and surfaces of the porous grains (30a).
다음으로 분리 단계(s130)로서, 예를 들어 미세 거름망을 이용하여 잔존하는 혼합 용액(M)과 다공성 알갱이(30a)를 분리할 수 있다(도 5의 (d)). 이후 실시예에 따라, 향후 혹시라도 누액이 발생할 가능성을 없애기 위하여, 다공성 알갱이(30a)에 흡수되지는 않았으나 표면장력 등의 현상으로 여전히 다공성 알갱이(30a)에 과도하게 묻어 있는 혼합 용액(M)을 건조시키는 건조 단계가 추가로 포함될 수 있다.Next, in the separation step (s130), the remaining mixed solution (M) and the porous grains (30a) can be separated using, for example, a fine strainer (FIG. 5(d)). According to the following embodiments, in order to eliminate the possibility of liquid leakage occurring in the future, the mixed solution (M), which has not been absorbed into the porous grains (30a) but is still excessively embedded in the porous grains (30a) due to phenomena such as surface tension, is A drying step may be additionally included.
다음으로, 혼합 용액(M)이 증점제를 포함하는 경우에는, 혼합 용액(M)을 흡습한 다공성 알갱이(30a)들을 냉각시켜 흡습된 액상 에어로졸 매질을 겔상화할 수 있다.Next, when the mixed solution (M) includes a thickener, the porous particles 30a that have absorbed the mixed solution (M) can be cooled to gel the moisture-absorbed liquid aerosol medium.
도 6은 본 발명의 일 실시예에 따른, 고형화된 에어로졸 매질을 포함하는 에어로졸 매질 집합체(30)의 제조 방법을 나타낸 순서도이다. 본 실시예 역시 이해를 돕기 위하여 도 5 및 그에 포함된 동일한 참조부호를 이용하여 설명한다. 먼저, 용액 준비 단계(s210)로서 용기(K)에 액상의 에어로졸 매질(예를 들어, PG와 VG 혼합물)과 증점제와 용해제의 혼합 용액(M)을 준비한다(도 5의 (a)). 다음으로 흡습 단계(s220)로서, 다공성 알갱이(30a)들을 용기(K)로 도입하여 상기 혼합 용액(M)에 적신다(도 5의 (b), (c)). 예를 들어 이 때 다공성 알갱이(30a)가 잘 적셔지도록 교반 작업이 수행될 수 있다. 그로 인하여, 다공성 알갱이(30a)와 에어로졸 매질과 증점제와 용해제의 혼합 용액(M)이 혼합되며 다공성 알갱이(30a)의 마이크로 기공 및 표면에 상기 혼합 용액(M)이 흡습 내지 수용될 수 있다. 다음으로 분리 단계(s230)로서, 예를 들어 미세 거름망을 이용하여 잔존하는 혼합 용액(M)과 다공성 알갱이(30a)를 분리할 수 있다(도 5의 (d)). 다음으로 고형화 단계(s240)로서, 다공성 알갱이(30a)에 흡습된 혼합 용액(M)에 포함된 용해제를 증발시켜 고형화된 에어로졸 매질을 얻는 단계이다. 예를 들어, 혼합 용액(M)을 흡습한 다공성 알갱이(30a)를, 포함된 용해제의 끓는 점보다는 높고, 포함된 에어로졸 매질 및 증점제의 끓는 점보다 낮은 온도로 가열하여, 혼합 용액(M)에 포함된 용해제를 증발시키고, 에어로졸 매질 및 증점제는 그대로 남도록 하여 고형화된 에어로졸 매질을 얻을 수 있다. 이 과정에서 에어로졸 매질은 다공성 알갱이(30a) 내의 마이크로 기공(A)이나 다공성 알갱이(30a)들 사이의 매크로 기공(B)에 수용된 채 고형화될 수 있다.Figure 6 is a flowchart showing a method of manufacturing an aerosol medium assembly 30 including a solidified aerosol medium according to an embodiment of the present invention. To facilitate understanding, this embodiment will also be described using FIG. 5 and the same reference numerals included therein. First, as a solution preparation step (s210), a mixed solution (M) of a liquid aerosol medium (for example, a mixture of PG and VG), a thickener, and a solubilizing agent is prepared in the container (K) (FIG. 5(a)). Next, in the moisture absorption step (s220), the porous granules (30a) are introduced into the container (K) and soaked in the mixed solution (M) (FIG. 5 (b), (c)). For example, at this time, stirring may be performed to ensure that the porous grains 30a are well wetted. As a result, the porous grains (30a) and the mixed solution (M) of the aerosol medium, thickener, and solubilizer are mixed, and the mixed solution (M) may be absorbed or accommodated in the micropores and surfaces of the porous grains (30a). Next, in the separation step (s230), the remaining mixed solution (M) and the porous grains (30a) can be separated using, for example, a fine strainer (FIG. 5(d)). Next is the solidification step (s240), which is a step of obtaining a solidified aerosol medium by evaporating the solvent contained in the mixed solution (M) moisture absorbed by the porous grains (30a). For example, the porous grains (30a) that have absorbed the mixed solution (M) are heated to a temperature higher than the boiling point of the included solvent and lower than the boiling points of the included aerosol medium and thickener, and added to the mixed solution (M). A solidified aerosol medium can be obtained by evaporating the contained solvent, leaving the aerosol medium and thickener as is. In this process, the aerosol medium may be solidified while being accommodated in micro pores (A) within the porous grains (30a) or macro pores (B) between the porous grains (30a).
이렇게 제조한, 액상의 또는 겔상의 또는 고형화상의 에어로졸 매질을 수용한 다공성 알갱이(30a)들은 도 1에서와 같이 에어로졸 매질 로드의 형태로 랩핑 페이퍼(31)에 의해 랩핑 되거나 소정 공간 내에 장입되어 에어로졸 매질 집합체(30)를 형성하여, 에어로졸을 발생시키는 무화기로서 기능할 수 있다.The porous particles 30a containing the liquid, gel, or solid aerosol medium prepared in this way are wrapped by the wrapping paper 31 in the form of an aerosol medium rod as shown in FIG. 1 or inserted into a predetermined space to form an aerosol medium. By forming an aggregate 30, it can function as an atomizer that generates an aerosol.

도 10은 본 발명의 또 다른 실시예에 따른 가열식 흡연 물품(1c)의 내부를 개념적으로 나타낸 수직 단면도이다. 본 실시예의 가열식 흡연 물품(1c)은 도 7의 가열식 흡연 물품(1)과 비교하여, 에어로졸 매질 집합체(35)는 그 중심부를 상하로 관통하도록 형성된 중공을 포함하도록 배치되고, 상기 중공에는 담배체(41)가 구비되는 점을 달리한다.Figure 10 is a vertical cross-sectional view conceptually showing the inside of a heated smoking article 1c according to another embodiment of the present invention. In the heated smoking article 1c of the present embodiment, compared to the heated smoking article 1 of FIG. 7, the aerosol medium aggregate 35 is arranged to include a hollow formed to penetrate upward and downward through the center, and the hollow contains a tobacco body. (41) is provided differently.
예를 들어 에어로졸 매질 집합체(35)에 냉각 튜브 로드(20)의 중공(22)과 동일한 직경의, 또한 동일한 중심축을 공유하는 중공을 형성하고, 그 중공에 담배체(41)를 채워 넣을 수 있다. 이 때 담배체(41)가 채워진 중공은 냉각 튜브 로드(20)의 중공(22)과 연결되는 기류 패스의 역할을 할 수 있다. 본 실시예의 에어로졸 매질 집합체(35) 역시 실시예에 따라, 로드(rod)를 형성하기 위하여 별도의, 바람직하게는 방수 기능을 갖는, 랩핑 페이퍼에 랩핑될 수 있다.For example, a hollow having the same diameter and sharing the same central axis as the hollow 22 of the cooling tube rod 20 may be formed in the aerosol medium assembly 35, and the tobacco body 41 may be filled into the hollow. . At this time, the hollow filled with the tobacco body 41 may serve as an airflow path connected to the hollow 22 of the cooling tube rod 20. Depending on the embodiment, the aerosol medium aggregate 35 may also be wrapped in a separate, preferably waterproof, wrapping paper to form a rod.
예를 들어 가열식 흡연 물품(1c)이 어느 에어로졸 발생 장치 내에 삽입되고, 그에 포함된 히터에 의해 에어로졸 매질 집합체(35)의 외곽이 가열되면, 에어로졸 매질 집합체(35)의 다공성 알갱이(30a)에 포함된 에어로졸 매질이 에어로졸로 변환되어 상기 에어로졸 매질 집합체(35)의 중공으로 도입될 수 있다. 이 때, 이 뜨거운 에어로졸이 담배체(41)를 가열하여 담배체(41)로부터 역시 에어로졸이 발생할 수 있으며, 상기의 두 출처의 에어로졸이 혼합되어, 냉각 튜브 로드(20) 및 필터 로드(10)를 거쳐 사용자에게 흡입될 수 있다.For example, when the heated smoking article (1c) is inserted into an aerosol generating device and the exterior of the aerosol medium assembly (35) is heated by the heater included therein, the heated smoking article (1c) is included in the porous particles (30a) of the aerosol medium assembly (35). The aerosol medium may be converted into an aerosol and introduced into the hollow of the aerosol medium assembly 35.

예를 들어 담배체(41)를 원통 형태로 먼저 뭉친 후, 그것을 인서트한 채 다공성 알갱이(30a)를 외곽에 채우는 방법으로 에어로졸 매질 집합체(35)를 제조할 수 있다. 또는 담배체(41)를 원통 형태로 먼저 뭉친 후, 그것을 메쉬 또는 다수의 통공을 갖는 별도의 랩핑 페이퍼로 랩핑하여, 그것을 인서트한 채 다공성 알갱이(30a)를 외곽에 채우는 방법으로 에어로졸 매질 집합체(35)를 제조할 수 있다. 이 경우, 상기 메쉬 또는 다수의 통공을 갖는 별도의 랩핑 페이퍼는 에어로졸 매질 집합체(35)에 형성된 중공과 에어로졸 매질 집합체(35)의 경계를 실질적으로 정의하며 통기막의 역할을 한다. 또는 그 횡단면이 도넛 형상이 되도록, 중공이 형성된 에어로졸 매질 집합체(35)의 내측과 외측을 메쉬 또는 다수의 통공을 갖는 별도의 랩핑 페이퍼로 감싼 후, 형성된 중공에 담배체(41)를 채워 넣어 에어로졸 매질 집합체(35)를 제조할 수도 있다.For example, the aerosol medium aggregate 35 can be manufactured by first agglomerating the tobacco body 41 into a cylindrical shape, inserting the tobacco body 41, and then filling the outside with porous particles 30a. Alternatively, the tobacco body 41 is first lumped into a cylindrical shape, then wrapped with mesh or a separate wrapping paper having a plurality of holes, and the aerosol medium aggregate 35 is formed by inserting the tobacco body 41 and filling the outside with the porous granules 30a. ) can be manufactured. In this case, the mesh or a separate wrapping paper having multiple holes substantially defines the boundary between the hollow formed in the aerosol medium assembly 35 and the aerosol medium assembly 35 and serves as a breathable membrane. Alternatively, the inside and outside of the hollow aerosol medium assembly 35 are wrapped with mesh or a separate wrapping paper having a plurality of holes so that the cross section has a donut shape, and then the tobacco body 41 is filled into the formed hollow to produce aerosol. A medium assembly 35 may also be manufactured.
