Description

에어로졸 발생장치용 금속섬유 면상발열 히터{METAL FIBER PLANE HEATER FOR AEROSOL GENERATOR}Metal fiber surface heating heater for aerosol generator {METAL FIBER PLANE HEATER FOR AEROSOL GENERATOR}

본 발명은 에어로졸 발생장치용 금속섬유 면상발열 히터에 관한 것이다. The present invention relates to a metal fiber surface heating heater for an aerosol generator.

최근 궐련 담배의 흡연 시 발생할 수 있는 부작용을 개선할 수 있는 다양한 형태의 에어로졸 발생장치들이 개발되고 있다. 이러한 에어로졸 발생장치들은 담뱃잎을 압축하여 필터와 함께 종이에 감싼 지궐련을 가열하여 에어로졸을 발생시키는 타입과, 액상형 카트리지 내에 충진된 액상을 기화시켜 에어로졸을 발생시키는 액상 타입으로 크게 구분된다. Recently, various types of aerosol generators capable of improving side effects that may occur during cigarette smoking have been developed. These aerosol generators are largely divided into a type that generates aerosol by compressing tobacco leaves and heating a cigarette wrapped in paper together with a filter, and a liquid type that generates aerosol by vaporizing a liquid filled in a liquid type cartridge.

액상 타입의 경우 초음파 진동자를 이용하여 에어로졸을 발생시키는 에어로졸 발생장치가 간혹 존재하나, 대부분의 에어로졸 발생장치는 궐련 또는 액상을 가열하는 히터를 구비한다. In case of the liquid type, there are some aerosol generators that generate aerosols using ultrasonic vibrators, but most of the aerosol generators are provided with a cigarette or a heater for heating the liquid.

히터를 구비하는 에어로졸 발생 장치는 배터리, 제어회로, 전기 가열식 히터를 포함한다. 전기 가열식 히터가 에어로졸 형성 기재를 가열하여 에어로졸을 발생시키는데, 에어로졸 형성 기재가 열을 고르게 받지 못하면 그을음이 발생하거나, 에어로졸 발생량이 부족해지는 등 에어로졸 발생에 문제가 생길 수 있다. An aerosol generating device with a heater includes a battery, a control circuit, and an electric heater. The electric heating type heater heats the aerosol-forming substrate to generate aerosol. If the aerosol-forming substrate does not receive heat evenly, there may be problems in aerosol generation, such as soot generation or an insufficient amount of aerosol generation.

전기에너지를 열에너지로 변환시키는 발열체는 일반적으로 금속 또는 세라믹 선으로 만들어진 선상 발열체, 고분자 필름, 탄소계 발열체, 은나노 발열체 등을 이용한 면상발열체가 있다. 선상 발열체는 발열선의 간격에 따라 구역별 온도 편차가 심한 문제점이 있으며, 고분자 필름, 탄소계 발열체, 은나노 발열체를 이용한 면상발열체는 한계 온도가 낮아 에어로졸 발생 장치에는 적합하지 않다.A heating element that converts electrical energy into thermal energy generally includes a linear heating element made of metal or ceramic wire, a planar heating element using a polymer film, a carbon-based heating element, a silver nano heating element, and the like. The linear heating element has a problem of severe temperature deviation by zone depending on the spacing of the heating wire, and the planar heating element using a polymer film, carbon-based heating element, and silver nano heating element has a low limit temperature and is not suitable for an aerosol generating device.

에어로졸 형성 기재에 열을 고르게 전달하기 위해서 면상발열체를 활용하는 새로운 기술 개발이 요구 된다.In order to evenly transfer heat to the aerosol-forming substrate, the development of a new technology using a planar heating element is required.

도 1은 금속섬유 면상발열 히터의 원리를 개략적으로 도시한 도면이다. 금속섬유를 면상발열 히터는, 동일한 성분으로 이루어진 두 가닥 이상의 금속 섬유를 직조한 직물 형태의 히터이다. 직조 방식은, 제직이나 브레이딩 등 어떠한 방식으로 이루어져도 무방하며, 효율은 떨어지나 편직 방식으로 직조한 형태여도 무방하다. 도 1에서는 금속 섬유를 편직 형태로 제직한 면상발열 히터를 예시로 들었다. 금속섬유 면상발열 히터(100)는 복수 개의 경사(110)의 앞 뒤를 복수 개의 위사(120)가 어긋나게 가로질러 직조되며, 모든 경사(110)의 양 단에 전극(130)이 접합된다. 따라서 모든 경사는 전극(130)의 양극에 병렬 연결된 형태이다. 금속 섬유의 소재는 SUS316L인 것이 바람직하며, 전극(130)은 니켈(Ni)로 제조된다. 이때, 면상발열 히터를 구성하는 금속섬유인 경사(110)와 위사(120)는 모두 금속섬유는 전기 전도성 금속으로 이루어지며 표면에 절연 코팅이 이루어진다. 전극(130)과 경사(110)의 접합은 전기 저항용접(Spot Welding)을 통해 이루어진다. 1 is a diagram schematically illustrating the principle of a metal fiber surface heating heater. A metal fiber surface heating heater is a heater in the form of a fabric in which two or more metal fibers made of the same component are woven. The weaving method may be made by any method such as weaving or braiding, and it may be woven in a less efficient but knitting method. In FIG. 1, a surface heating heater in which metal fibers are woven in a knitted form is taken as an example. The metal fiber planar heating heater 100 is woven by crossing a plurality of weft yarns 120 with a shift in the front and back of a plurality of warp yarns 110, and electrodes 130 are bonded to both ends of all warp yarns 110. Therefore, all the slopes are connected in parallel to the anode of the electrode 130. The material of the metal fiber is preferably SUS316L, and the electrode 130 is made of nickel (Ni). At this time, both the warp yarn 110 and the weft yarn 120, which are metal fibers constituting the surface heating heater, are made of electrically conductive metal, and an insulating coating is formed on the surface. The junction of the electrode 130 and the slope 110 is made through electric resistance welding (Spot Welding).

제1 실시예에 따른 에어로졸 발생장치용 금속섬유 면상발열 히터는 원통형의 면상발열체(100a) 내부에 원통형의 에어로졸 발생 구역이 형성된다. 이때, 에어로졸 발생 구역에는 면상발열체(100a)에 의해 가열되는 원통형 금속 파이프(200)가 구비될 수 있다. 이때 금속 파이프(200)는 SUS 재질인 것이 바람직하다. 금속 파이프(200) 내부의 공동(210)에는 궐련 등의 에어로졸 발생 기질이 수용되어 가열될 수 있다. 이때 면상발열체(100a)는 도 1에 도시된 바와 같이 제직 방식으로 직조된 다음 금속 파이프(200)의 외주면을 감싸도록 부착 또는 설치될 수도 있으나, 도 3에 도시된 것처럼 금속 파이프(200)의 외주에서 브레이딩되면서 직조와 설치가 동시에 이루어질 수도 있다. In the metal fiber planar heating heater for an aerosol generating device according to the first embodiment, a cylindrical aerosol generating zone is formed inside the cylindrical planar heating element 100a. At this time, the aerosol generation zone may be provided with a cylindrical metal pipe 200 heated by the planar heating element 100a. At this time, the metal pipe 200 is preferably made of SUS material. An aerosol-generating substrate such as a cigarette may be accommodated and heated in the cavity 210 inside the metal pipe 200 . At this time, the planar heating element 100a may be woven in a weaving method as shown in FIG. 1 and then attached or installed to surround the outer circumferential surface of the metal pipe 200, but as shown in FIG. 3, the outer circumference of the metal pipe 200 Weaving and installation may be performed at the same time while braiding.

It is an illustrated drawing.

본 발명의 제3 실시예에 따르면, 에어로졸 발생장치용 금속섬유 면상발열 히터는 면상발열체(100c)와 전극(130c)이 다공성 세라믹(400)의 저면에 설치되어 면상발열체(100c)가 다공성 세라믹(400)을 가열하는 형태이다. 다공성 세라믹(400)은 액상 형태의 에어로졸 발생 기질을 머금고 있으며, 면상발열체(100c)의 발열에 의해 가열되며, 액상 형태의 에어로졸 발생 기질이 기화되어 에어로졸이 생성된다. According to the third embodiment of the present invention, in the metal fiber planar heating heater for an aerosol generator, the planar heating element 100c and the electrode 130c are installed on the bottom surface of the porous ceramic 400 so that the planar heating element 100c is a porous ceramic ( 400) in the form of heating. The porous ceramic 400 contains an aerosol-generating substrate in liquid form, and is heated by heat generated by the surface heating element 100c, and the aerosol-generating substrate in liquid form is vaporized to generate an aerosol.

일반적으로 다공성 세라믹(400)은 실리게이트, 바인더, 조공제 혼합하여 슬러리로 제조하고 성형, 건조한 다음 소결하여 제조된다. 다공성 세라믹(400)에 면상발열체(100c)와 전극(130c)가 매립되거나, 다공성 세라믹(400)의 표면 부근에 면상발열체(100c)와 전극(130c)이 결합되어 적어도 일부가 노출될 수 있다. 면상발열체(100c)는 다공성 세라믹(400)의 소결 전 성형 시에 인서트 되어 일체로 결합될 수도 있고, 다공성 세라믹(400)의 제조 후에 별도의 공정을 거쳐 결합될 수도 있다. 전극(130c)은 면상발열체(100c)와 함께 다공성 세라믹(400)에 인서트 사출될 수 있고, 면상발열체(100c)만 다공성 세라믹(400)에 인서트 사출되고 전극(130c)은 사출 성형 이후에 결합되거나 그 반대일 수도 있다. 면상발열체(100c)가 다공성 세라믹(400) 성형 시에 인서트 된 다음 소결될 경우, 면상발열체(100c)의 산화를 방지하기 위해 소결 온도는 700~800℃인 것이 바람직하다. In general, the porous ceramic 400 is prepared by mixing a silicate, a binder, and a pore-forming agent to form a slurry, molding, drying, and then sintering. The planar heating element 100c and the electrode 130c are embedded in the porous ceramic 400, or the planar heating element 100c and the electrode 130c are coupled near the surface of the porous ceramic 400, so that at least a portion may be exposed. The planar heating element (100c) may be inserted and integrally combined during molding before sintering of the porous ceramic 400, or may be combined through a separate process after manufacturing the porous ceramic 400. The electrode 130c may be insert-injected into the porous ceramic 400 together with the planar heating element 100c, and only the planar heating element 100c is insert-injected into the porous ceramic 400 and the electrode 130c is bonded after injection molding, or It could be the other way around. When the planar heating element 100c is inserted during molding of the porous ceramic 400 and then sintered, the sintering temperature is preferably 700 to 800° C. to prevent oxidation of the planar heating element 100c.

이때, 다공성 세라믹(400)의 일면에 결합되는 면상발열체(100c)는 다공성 세라믹(400)의 가장 넓은 면에 설치되어 접촉 면적과 발열 면적을 최대화하는 것이 바람직하다. 다공성 세라믹(400)과 결합하는 면상발열체(100c) 또한 경사(110c)와 위사(120c)를 엮어서 직조하며, 경사(110c)의 양단이 각 전극(130c)에 결합된 형태이다. 이때, 발열면을 최대화하기 위해 다공성 세라믹(400c)에 경사(110c)와 위사(120c)의 길이가 동일하지 않은 경우, 즉 면상발열체(100c)가 설치되는 다공성 세라믹(400c)이 가로와 세로의 길이가 동일하지 않은 경우, 경사(110c)가 위사(120c)보다 더 긴 길이를 가지도록 배치되는 것이 바람직하다. 전극(130c)과 연결되는 경사(110c)의 길이는 위사(120c)와 같거나 유사한 길이를 가지므로, 전극(130c)이 차지하는 면적을 줄일 수 있고, 따라서 면상발열체(100c)의 설치 면적을 최대화할 수 있다. At this time, it is preferable that the planar heating element 100c coupled to one surface of the porous ceramic 400 is installed on the widest surface of the porous ceramic 400 to maximize the contact area and heating area. The planar heating element 100c combined with the porous ceramic 400 is also woven by weaving the warp yarn 110c and the weft yarn 120c, and both ends of the warp yarn 110c are coupled to each electrode 130c. At this time, in order to maximize the heating surface, when the lengths of the warp yarns 110c and the weft yarns 120c are not the same in the porous ceramic 400c, that is, the porous ceramic 400c in which the planar heating element 100c is installed has horizontal and vertical If the lengths are not the same, it is preferable that the warp yarns 110c are arranged to have a longer length than the weft yarns 120c. Since the length of the warp yarn 110c connected to the electrode 130c has the same or similar length as the weft yarn 120c, the area occupied by the electrode 130c can be reduced, thus maximizing the installation area of the planar heating element 100c. can do.
