에어로졸 발생 장치Aerosol generator

본 출원은 2018년 4월 12일자 한국 특허 출원 제10-2018-0042949호에 기초한 우선권의 이익을 주장하며, 해당 한국 특허 출원의 문헌에 개시된 모든 내용은 본 명세서의 일부로서 포함한다.This application claims the benefit of priority based on Korean Patent Application No. 10-2018-0042949 dated April 12, 2018, and all content disclosed in the literature of that Korean patent application is incorporated as part of this specification.

본 발명은 담배의 대용으로 사용될 수 있는 에어로졸 발생 장치에 관한 것이다. The present invention relates to an aerosol-generating device that can be used as a substitute for tobacco.

에어로졸 발생 장치의 일반적인 유형으로는 전기 작동식 흡연 장치를 들 수 있다. 공지된 전기 작동식 흡연 장치는, 도 1에 도시된 바와 같이, 전형적으로, 배터리를 포함하고 있는 에어로졸 발생 수단(1) 및 에어로졸 발생 수단과 함께 사용하도록 특정하게 설계된 에어로졸 발생 물품(3)을 포함하며, 상기 에어로졸 발생 수단(1)은 에어로졸 발생 물품(3)을 가열하기 위한 전기 히터를 포함하고 있다.Common types of aerosol-generating devices include electrically actuated smoking devices. Known electrically actuated smoking devices, as shown in FIG. 1, typically comprise an aerosol-generating means 1 comprising a battery and an aerosol-generating article 3 specifically designed for use with the aerosol-generating means. The aerosol-generating means 1 comprises an electric heater for heating the aerosol-generating article 3.

상기 전기 작동식 흡연 장치의 일예로서, 상기 에어로졸 발생 물품(3)은 담배 플러그와 같은 에어로졸 형성 기재의 플러그를 포함하고, 상기 에어로졸 발생 물품(3)이 에어로졸 발생 수단(1) 내에 삽입될 때, 에어로졸 발생 수단(1) 내에 수용된 히터가 에어로졸 발생 기재 내에 삽입된다. As an example of the electrically actuated smoking device, the aerosol-generating article 3 comprises a plug of an aerosol-forming substrate such as a cigarette plug, and when the aerosol-generating article 3 is inserted into the aerosol-generating means 1, The heater accommodated in the aerosol-generating means 1 is inserted into the aerosol-generating substrate.

그러나, 상기와 같은 형태의 흡연 장치에서 전기 히터는, 에어로졸 발생 기재와 직접적으로 접촉하므로, 사용 도중 에어로졸 형성 기재로부터 나온 물질로 오염될 수 있으며, 그에 따라 열 전달 효율 감소되며, 탄화에 의한 이취가 발생되는 문제를 야기한다. However, in the smoking device of this type, the electric heater is in direct contact with the aerosol-generating substrate, and thus can be contaminated with material from the aerosol-forming substrate during use, thereby reducing the heat transfer efficiency and causing the odor by carbonization. Cause problems that occur.

그러므로, 장치 내부의 전기 히터를 자주 세척할 필요성이 발생하나, 장치 내부의 좁은 공간에 설치된 히터를 세척하는 것이 용이하지 않다는 문제가 있다. 따라서, 세척이 곤란한 경우에는 장치 전체를 폐기해야 하는 경우도 발생한다. Therefore, there is a need to frequently clean the electric heater inside the apparatus, but there is a problem that it is not easy to clean the heater installed in the narrow space inside the apparatus. Therefore, when it is difficult to wash, the entire apparatus needs to be discarded.

또한, 상기와 같은 히터의 오염으로 인하여 흡연 후에 에어로졸 발생 수단(1)으로부터 에어로졸 발생 물품(3)을 제거하는 것이 어려울 수도 있다.In addition, it may be difficult to remove the aerosol-generating article 3 from the aerosol-generating means 1 after smoking due to such contamination of the heater.

그러므로, 상기와 같은 문제를 해결할 수 있는 기술의 개발이 요구되고 있다. Therefore, the development of a technology that can solve the above problems is required.

본 발명의 에어로졸 발생 장치(300)는, 도 2 및 도 3에 도시된 바와 같이, 에어로졸 발생 기재 카트리지(10), 냉각부(20), 및 필터부(30)를 포함하며, 상기 카트리지(10)를 관통하여 구비된, 관형태이며 관벽에 하나 이상의 관통공(42)이 형성된 열전달 부재(40)를 포함하는 에어로졸 발생 물품(100); 및As shown in FIGS. 2 and 3, the aerosol-generating device 300 of the present invention includes an aerosol-generating substrate cartridge 10, a cooling unit 20, and a filter unit 30, and the cartridge 10. An aerosol-generating article (100) comprising a heat transfer member (40) having a tubular shape and having at least one through hole (42) formed in the pipe wall; And

에어로졸 발생 물품 수용홈(60) 및 상기 에어로졸 발생 물품 수용홈(60)의 바닥에 구비된 히터 부재(70)를 포함하는 에어로졸 발생 수단(200);을 포함하며,And aerosol-generating means 200 including an aerosol-generating article accommodating groove 60 and a heater member 70 provided on the bottom of the aerosol-generating article accommodating groove 60.

상기 에어로졸 발생 물품(100)의 열전달 부재(40)와 에어로졸 발생 수단(200)의 히터 부재(70)는 히터 부재에 형성된 돌출부가 열전달 부재(40)의 관공(41)에 삽입되거나, 카트리지(10)의 하단부 밖으로 돌출된 열전달 부재의 돌출부(44)가 히터 부재에 형성된 홈부(74)에 삽입되어 접촉을 형성하는 특징을 갖는다. In the heat transfer member 40 of the aerosol-generating article 100 and the heater member 70 of the aerosol-generating means 200, protrusions formed in the heater member are inserted into the holes 41 of the heat transfer member 40 or the cartridge 10. The projection 44 of the heat transfer member protruding out of the lower end of the c) is inserted into the groove 74 formed in the heater member to form a contact.

본 발명의 일 실시형태에서 상기 카트리지(10)에 수용되는 에어로졸 발생 기재는 솜, 필터, 면사, 실리카 및 스펀지 등으로 이루어진 군으로부터 선택되는 1종 이상의 흡수부재에 함침된 상태일 수 있다. In one embodiment of the present invention, the aerosol-generating substrate contained in the cartridge 10 may be impregnated with at least one absorbing member selected from the group consisting of cotton, a filter, cotton yarn, silica, a sponge, and the like.

본 발명의 일 실시형태에서 상기 카트리지(10)에 수용되는 에어로졸 발생 기재는 액상, 졸(sol), 또는 겔(gel) 형태일 수 있다. In one embodiment of the present invention, the aerosol-generating substrate contained in the cartridge 10 may be in the form of a liquid, a sol, or a gel.

본 발명의 일 실시형태에서 상기 열전달 부재(40)의 관공(41)은 직경이 1 mm ~ 4 mm의 범위로 형성될 수 있다. In one embodiment of the present invention, the hole 41 of the heat transfer member 40 may be formed in the range of 1 mm to 4 mm in diameter.

본 발명의 일 실시형태에서 상기 열전달 부재(40)의 관벽에 형성된 관통공(42)은 직경이 0.5 mm ~ 2 mm 일 수 있다. 상기 관통공(42)은 에어로졸이 통과하는 구멍으로서, 에어로졸이 잘 통과할 수 있는 사이즈로 형성되는 것이 바람직하며, 열전달 부재의 관공(41)의 사이즈에 연동하여 그 사이즈가 정해질 수 있다. 예를 들어, 관공의 사이즈가 큰 경우 관통공의 사이즈도 크게 형성될 수 있으며, 관공의 사이즈가 작은 경우 관통공의 사이즈도 작게 형성될 수 있다. In one embodiment of the present invention, the through hole 42 formed in the tube wall of the heat transfer member 40 may have a diameter of 0.5 mm to 2 mm. The through hole 42 is a hole through which the aerosol passes, and is preferably formed in a size through which the aerosol can pass. The size of the through hole 42 may be determined in conjunction with the size of the tube 41 of the heat transfer member. For example, when the size of the hole is large, the size of the through hole may also be large, and when the size of the hole is small, the size of the through hole may also be small.

본 발명의 일 실시형태에서 상기 열전달 부재(40)의 냉각부(20) 방향 말단 관공(41)에는 에어로졸 보다 입자 직경이 더 큰 물질을 차단하는 필터(미도시)가 더 구비될 수도 있다. In one embodiment of the present invention, the end hole (41) in the cooling unit 20 direction of the heat transfer member 40 may be further provided with a filter (not shown) for blocking a material having a larger particle diameter than the aerosol.

상기 필터로는 이 분야에서 공지된 것이 제한 없이 사용될 수 있다.As the filter, those known in the art may be used without limitation.

본 발명에 있어서, 상기 에어로졸 발생 기재 카트리지(10)의 형태는 특별히 한정되지 않으나, 원기둥 형태가 일반적으로 사용되고 있다. 상기 카트리지는 에어로졸 발생 기재가 누출되지 않도록 밀봉된 용기로 제조될 수 있으며, 열전달 부재(40)을 더 포함하는 것을 제외하고는 이 분야에서 공지된 형태가 제한 없이 사용될 수 있다. In the present invention, the form of the aerosol-generating substrate cartridge 10 is not particularly limited, but a cylindrical form is generally used. The cartridge may be manufactured in a sealed container so that the aerosol-generating substrate does not leak, and any form known in the art may be used without limitation, except that the cartridge further includes a heat transfer member 40.

본 발명의 일 실시형태에서 상기 열전달 부재(40)의 돌출부(44)는, 도 3에 도시된 바와 같이, 관벽에 관공(41)을 포함하지 않으며, 선단부가 막힌(폐쇄된) 형태일 수 있다. 왜냐하면, 상기 돌출부(44)는 에어로졸 발생 기재 카트리지(10)에 수용된 에어로졸 발생 기재와 접하고 있지 않으므로, 관공(41)이 불필요하며, 관공(41)이 오히려 열전달 효율을 저하시킬 가능성도 있기 때문이다. 또한, 카트리지(10)에 수용된 에어로졸 발생 기재가 관공(41)을 통하여 누출될 가능성은 적지만, 기재의 누출을 고려하여 돌출부(44)의 말단을 폐쇄하는 것이 바람직하며, 이 경우 열전달 효율도 더 향상될 수 있기 때문이다.In one embodiment of the present invention, as shown in FIG. 3, the protrusion 44 of the heat transfer member 40 does not include a hole 41 in the pipe wall, and may have a shape in which the tip is blocked (closed). . This is because the protrusions 44 do not come into contact with the aerosol-generating substrate contained in the aerosol-generating substrate cartridge 10, so that the holes 41 are unnecessary, and the holes 41 may rather reduce the heat transfer efficiency. In addition, although the aerosol-generating substrate contained in the cartridge 10 is less likely to leak through the hole 41, it is preferable to close the end of the protrusion 44 in consideration of the leakage of the substrate, in which case the heat transfer efficiency is further increased. Because it can be improved.

또한, 본 발명에 있어서, 에어로졸 발생 물품(100)의 열전달 부재(40)와 에어로졸 발생 수단(200)의 히터 부재(70)의 접촉과 관련하여, 상기 열전달 부재(40)의 선단부에는, 도 4에 도시된 바와 같이, 관공(41)을 기밀하게 차단하면서 히터 부재의 돌출부(72)가 결합되는 홈부(46)를 형성하는 격벽(49)이 더 구비될 수 있다. 상기 격벽(49)은 카트리지(10)에 수용된 에어로졸 발생 기재가 관공(41)을 통하여 누출될 경우를 대비하기 위하여 구비될 수 있다. In addition, in the present invention, with respect to the contact between the heat transfer member 40 of the aerosol-generating article 100 and the heater member 70 of the aerosol-generating means 200, the front end of the heat transfer member 40, Fig. 4 As shown in FIG. 3, a partition wall 49 may be further provided to form a groove 46 to which the protrusion 72 of the heater member is coupled while blocking the tube 41 airtightly. The partition 49 may be provided in case the aerosol-generating substrate contained in the cartridge 10 leaks through the hole 41.
