본 발명은 다공성 세라믹 히터 파이프와 이를 포함하는 에어로졸 발생 장치에 관한 것으로, 더욱 상세하게는, 다공성 세라믹 내측에 금속 발열 부재를 구성한 히터 파이프와 이를 포함하는 에어로졸 발생 장치에 관한 것이다.The present invention relates to a porous ceramic heater pipe and an aerosol generating device including the same. More specifically, it relates to a heater pipe having a metal heating member inside a porous ceramic and an aerosol generating device including the same.
에어로졸은 대기 중에 부유상태로 존재하는 액체 또는 고체의 작은 입자로 보통 0.001 ~ 1.0 ㎛의 크기를 갖는다. 특히 여러 종류의 궐련형 에어로졸 발생 물품으로부터 유래하는 에어로졸을 사람이 흡입하는 경우가 있다. 예를 들어 궐련형 통상의 담배를 선호하는 수요자들의 요구에 따라, 통상의 담배의 필터부와, 궐련부의 모양을 갖는 전자 담배도 제안되고 있는데, 이 전자 담배는 궐련부에 포함된 흡입물질을 전자히터로 기화시키면 통상의 담배와 동등한 구성을 갖는 필터부를 통해 사용자가 흡입하는 구성을 갖는다. 도 1은 종래 기술에 따른 에어로졸 발생 장치의 일 예를 설명하기 위한 도면이다. 도 1을 참조하면, 에어로졸 발생 장치(100)에는 궐련형 에어로졸 발생 물품(10)이 삽입되는 공동(20)이 구비되며, 에어로졸 발생 장치(100)에 삽입된 궐련형 에어로졸 발생 물품(10)을 가열하여 에어로졸을 발생시키기 위해 예를 들어 공동(20) 외주에는 파이프 형태의 히터(30)가 구비된다. 또한, 에어로졸 발생 장치(100)에는 히터(30)에 전력을 공급하기 위한 배터리(40)와, 이 배터리(40)로부터 히터(30)에 공급되는 전력을 제어하도록 구성된 제어부(50)를 포함한다. 상술한 종래 기술에서는 제어부(50)의 제어에 의해 배터리(40)로부터 히터(30)에 전력을 공급하여 히터(30)에서 발생하는 열에 의해 궐련형 에어로졸 발생 물품(10)이 가열되어 궐련형 에어로졸 발생 물품(10) 내의 에어로졸 발생 기질로부터 에어로졸이 발생한다.Aerosols are small liquid or solid particles that exist in suspension in the atmosphere and usually have a size of 0.001 to 1.0 ㎛. In particular, there are cases where people inhale aerosols derived from various types of cigarette-type aerosol-generating products. For example, in response to the needs of consumers who prefer cigarette-type regular cigarettes, electronic cigarettes that have the filter part of a regular cigarette and the shape of a cigarette part are also being proposed. This electronic cigarette uses the inhaled substances contained in the cigarette part as electronic cigarettes. When vaporized with a heater, the user inhales it through a filter unit that has the same configuration as a regular cigarette. 1 is a diagram for explaining an example of an aerosol generating device according to the prior art. Referring to FIG. 1, the aerosol-generating device 100 is provided with a cavity 20 into which a cigarette-type aerosol-generating article 10 is inserted, and the cigarette-type aerosol-generating article 10 inserted into the aerosol-generating device 100 is provided with a cavity 20. In order to generate aerosol by heating, for example, a pipe-shaped heater 30 is provided on the outer periphery of the cavity 20. In addition, the aerosol generating device 100 includes a battery 40 for supplying power to the heater 30, and a control unit 50 configured to control the power supplied from the battery 40 to the heater 30. . In the above-described prior art, power is supplied from the battery 40 to the heater 30 under the control of the control unit 50, and the cigarette-type aerosol-generating article 10 is heated by the heat generated from the heater 30 to generate cigarette-type aerosol. An aerosol is generated from the aerosol-generating substrate within the generating article 10.
히터(30)는 에어로졸 발생 장치에 있어서 사용자 경험과 직결되는 핵심 요소로서, 특히 그 내부로 삽입되는 에어로졸 발생 물품(10)으로의 열 전달 능력을 개선할 필요가 있다. 이러한 요구에서 히터(30)의 재료로서 세라믹이 채택되고 있는데, 대한민국 등록특허 제10-2323138호에서는 세라믹 재질의 발열 히터가 개시되고 있으며, 제10-2211820호에서는 세라믹 재질의 궐련 지지부가 개시되고 있다. 세라믹 재질은 내열성이 우수하여 승온과 냉각이 반복되는 가혹한 환경에서도 장기 안정성이 뛰어나지만 외부로 누설되는 열이 많은 단점이 있다.The heater 30 is a key element directly related to the user experience in the aerosol generating device, and in particular, there is a need to improve the heat transfer ability to the aerosol generating article 10 inserted therein. In response to this demand, ceramic is being adopted as a material for the heater 30. Republic of Korea Patent No. 10-2323138 discloses a heating heater made of ceramic material, and in No. 10-2211820, a cigarette support portion made of ceramic material is disclosed. . Ceramic materials have excellent heat resistance and have excellent long-term stability even in harsh environments where heating and cooling are repeated, but they have the disadvantage of leaking a lot of heat to the outside.

본 발명에 있어서 몸체(150)는 다공성 물질로 형성되는 것을 특징으로 한다. 몸체(150)가 다공성 물질로 형성되는 경우, 내부 기공에 채워진 공기층에 의하여 단열 효과가 증가한다. 따라서 히터 파이프(1)가 가열되어도 열손실 되는 비중이 줄어, 히터로서의 성능이 증가하고 에너지 효율이 개선되며, 에어로졸 발생 장치 자체가 지나치게 가열되는 것을 방지할 수 있다. 종래의 히터 파이프형 에어로졸 발생 장치에 비하여 단열 성능이 개선되면서도 종래의 대류형 에어로졸 발생 장치에 비하여 열전달 효율은 높아진다. 다공성 물질로 형성되는 몸체(150)는 바람직하게는 세라믹 재질로 형성된다. 히터 파이프(1)에 있어서 몸체(150)는 잦은 가열과 냉각을 경험한다는 점에서 열 안정성이 뛰어난 세라믹 재질인 것이 바람직하다. 또한 세라믹은 전기전도성이 극히 낮아 추후 설명한 금속 재질의 히터(200)와 결합하여도 전기가 누설되지 않는다. 또한 단열성이 뛰어나 히터(200)에서 만들어 낸 열이 내측의 에어로졸 형성 물품으로 온전히 집중되도록 할 수 있다. 예를 들어 몸체(150)는 다공성의 유리, 산화 알루미늄, 산화 칼륨 또는 산화 마그네슘 중 어느 하나로 형성될 수 있다.In the present invention, the body 150 is characterized in that it is formed of a porous material. When the body 150 is made of a porous material, the insulation effect is increased by the air layer filled in the internal pores. Therefore, even when the heater pipe 1 is heated, the proportion of heat loss is reduced, thereby increasing heater performance and improving energy efficiency, and preventing the aerosol generating device itself from being excessively heated. Insulation performance is improved compared to a conventional heater pipe type aerosol generating device, while heat transfer efficiency is increased compared to a conventional convection type aerosol generating device. The body 150 made of a porous material is preferably made of a ceramic material. In the heater pipe 1, the body 150 is preferably made of a ceramic material with excellent thermal stability in that it experiences frequent heating and cooling. In addition, ceramic has extremely low electrical conductivity, so electricity does not leak even when combined with the metal heater 200 described later. In addition, it has excellent insulation properties, allowing the heat generated by the heater 200 to be completely concentrated on the aerosol-forming article inside. For example, the body 150 may be formed of any one of porous glass, aluminum oxide, potassium oxide, or magnesium oxide.
몸체(150)의 외측면은 실링을 위하여 코팅액으로 도포되어 실링층(153)을 형성한다. 실링층(153)은 몸체(150)의 외측면에 형성된 기공을 막아, 그를 통하여 기류, 에어로졸 입자, 또는 에어로졸 형성 물품에 함침된 액상이 누출되는 것을 막는다. 즉 기류의 누출을 막아 흡입 유동의 흡입력이 감소하는 것을 방지하고, 에어로졸 입자나 액상의 누출을 막아 히터 파이프(1) 바깥쪽이 오염되는 것을 방지한다. 코팅액은 기공의 실링이 가능한 다양한 물질이 사용될 수 있지만 방수성 물질로 형성되는 것이 액상의 누출을 막기 위한 목적에서 바람직하다. 예를 들어 실링층(153)은 유리막 코팅제, 발수 코팅막, 또는 멤브레인 코팅막 소재일 수 있다.The outer surface of the body 150 is coated with a coating liquid for sealing to form a sealing layer 153. The sealing layer 153 blocks pores formed on the outer surface of the body 150 to prevent airflow, aerosol particles, or liquid impregnated in an aerosol-forming article from leaking through the pores. In other words, it prevents the suction power of the suction flow from being reduced by preventing leakage of air flow, and prevents the outside of the heater pipe (1) from being contaminated by preventing the leakage of aerosol particles or liquid. Various materials capable of sealing pores may be used as the coating liquid, but it is preferable that the coating liquid be made of a waterproof material in order to prevent leakage of the liquid. For example, the sealing layer 153 may be a glass coating material, a water-repellent coating material, or a membrane coating material.
몸체(150)의 내측으로는 에어로졸 형성 물품의 수용 공간(151)을 향하여 금속 재질의 히터(200)(200a, 200b를 포함)가 설치된다. 금속 재질의 히터(200)는 저항 가열의 원리로 가열되어, 궁극적으로는 몸체(150) 내부에 삽입되는 에어로졸 형성 물품을 가열하여 에어로졸을 발생시킨다. 금속 재질의 히터(200)는 특히 몸체(150)의 측면과 또는 저면 중 어느 하나, 또는 양측 모두에 형성될 수 있다. 금속 재질의 히터(200)는 저항 가열되기 위하여 전기 접속부(200a)와 발열부(200b)로 구성된다. 전기 접속을 용이하게 하고 에어로졸 형성 물품을 효과적으로 가열하기 위해서는 전기 접속부(200a)는 몸체(150)의 내측 저면에, 발열부(200b)는 몸체(150)의 내측 측면에 형성되는 것이 바람직하다. 예를 들어 몸체(150)의 내측 저면 중 기류 홀(150)의 좌측에 형성되는 전기 접속부(200a)는 + 극성, 몸체(150)의 내측 저면 중 기류 홀(150)의 우측에 형성되는 전기 접속부(200a)는 - 극성과 접속하여 금속 재질의 히터(200)는 전체적으로 하나의 전기회로를 형성하여 저항 가열될 수 있다.Inside the body 150, heaters 200 (including 200a and 200b) made of metal are installed toward the accommodating space 151 of the aerosol-forming article. The heater 200 made of metal is heated based on the principle of resistance heating, ultimately heating the aerosol-forming article inserted into the body 150 to generate an aerosol. The heater 200 made of metal may be formed on either the side or bottom of the body 150, or on both sides. The heater 200 made of metal is composed of an electrical connection part 200a and a heating part 200b for resistance heating. In order to facilitate electrical connection and effectively heat the aerosol-forming article, it is preferable that the electrical connection portion 200a is formed on the inner bottom of the body 150 and the heating portion 200b is formed on the inner side of the body 150. For example, the electrical connection portion 200a formed on the left side of the airflow hole 150 on the inner bottom of the body 150 has a + polarity, and the electrical connection portion formed on the right side of the airflow hole 150 on the inner bottom of the body 150 has a positive polarity. (200a) is connected to the - polarity, so that the heater 200 made of metal can be resistively heated by forming an overall electric circuit.
에어로졸 형성 물품을 넓게 감싸서 고르게 가열하기 위해서는 발열부(200b)는 몸체(150)의 내측에 충분히 넓은 면적으로 고르게 분포되는 것이 바람직하다. 금속 재질의 히터(200)는 전기 접속부(200a)와 발열부(200b)를 포함하여 한 몸(one body)으로 형성될 수도 있고 여러 몸으로 형성된 후 서로 결합하여 하나로 조립될 수도 있다. 금속 재질의 히터(200)는 예를 들어 니켈크롬 합금, 철크롬알루미늄 합금, 니켈철 합금, 스테인리스 스틸, 순니켈, 티타늄 중 어느 하나로 형성될 수 있다.In order to heat the aerosol-forming article widely and evenly, it is preferable that the heating portion 200b be evenly distributed over a sufficiently large area inside the body 150. The heater 200 made of metal may be formed as one body including the electrical connection portion 200a and the heating portion 200b, or may be formed of multiple bodies and then combined to form one body. The heater 200 made of metal may be formed of, for example, any one of nickel-chromium alloy, iron-chrome-aluminum alloy, nickel-iron alloy, stainless steel, pure nickel, and titanium.
도 3은 본 발명의 일 실시예에 따른 몸체(150)의 구성을 설명하기 위한 단면도이다. 금속 재질의 히터(200)를 몸체(150)의 내측면에 설치하기 위하여 몸체(150)의 내측에는 에어로졸 형성 물품 수용 공간(151)을 향하도록 히터 수용홈(154)이 형성될 수 있다. 히터 수용홈(154)은 금속 재질의 히터(200)를 삽입 장착하기 위하여 몸체(150)의 내측 저면과, 내측 측면에 형성될 수 있다. 이렇게 히터 수용홈(154)을 몸체(150)에 형성하여 몸체(150)와 금속 재질의 히터(200)를 용이하게 조립할 수 있다. 히터 수용홈(154)의 깊이가 그에 삽입될 금속 재질의 히터(200)의 높이와 동일한 경우, 금속 재질의 히터(200)와 몸체(150)의 조립체는 비교적 평평한 내면을 가질 수 있어 바람직하다. 그러나 히터 수용홈(154)의 깊이보다 금속 재질의 히터(200)의 높이가 더 낮거나 더 높아도, 에어로졸 형성 물품의 가열이라는 목적 달성하는 모두 문제가 없다. 상기와 같은 실시예들을 도 4a, 4b, 4c에 예시적으로 도시하였다.Figure 3 is a cross-sectional view for explaining the configuration of the body 150 according to an embodiment of the present invention. In order to install the metal heater 200 on the inner surface of the body 150, a heater accommodating groove 154 may be formed on the inner side of the body 150 to face the aerosol-forming article accommodating space 151. The heater receiving groove 154 may be formed on the inner bottom and inner side of the body 150 to insert and install the metal heater 200. By forming the heater receiving groove 154 in the body 150 in this way, the body 150 and the heater 200 made of metal can be easily assembled. When the depth of the heater receiving groove 154 is the same as the height of the metal heater 200 to be inserted therein, the assembly of the metal heater 200 and the body 150 can have a relatively flat inner surface, which is preferable. However, even if the height of the metal heater 200 is lower or higher than the depth of the heater receiving groove 154, there is no problem in achieving the purpose of heating the aerosol-forming article. The above-described embodiments are exemplarily shown in FIGS. 4A, 4B, and 4C.
