도 1은 종래기술의 일 실시예에 따른 휴대용 에어로졸 발생장치를 개략적으로 도시한 단면도이다. 도 1을 참조하면 휴대용 에어로졸 발생장치(10)는 전류를 인가하면 저항에 의해 발열을 하는 히터(14)와 상기 히터(14)에 순간적으로 높은 전력을 공급할 수 있는 축전장치(16)와 상기 히터(14)를 제어하기 위한 마이크로컨트롤러(15)를 포함한다. 상기 히터(14)는, 공동(13)에 수용된 일정 온도 이상 가열시 기화하는 물질(기화 물질)이 포함된 기화재를 가열하여 에어로졸을 발생시킨다. 예를 들어, 흡입 물질이 함침되거나 표면에 묻혀진 종이로 채워진 에어로졸 형성기재(11)를 개구(12)를 통해 상기 공동(13)에 삽입하면 상기 히터(14)가 가열되어 에어로졸 형성기재(11) 내부의 흡입 물질을 기화시키면 사용자가 에어로졸 형성기재(11)의 필터부를 통해 기화되는 흡입 물질을 흡입할 수 있게 된다. 상술한 종래기술에 따른 에어로졸 발생장치(10)에서는 마이크로컨트롤러(15)에 타이머 또는 카운터가 내장되어 있어서, 기설정한 히팅시간에 따라 타이머 또는 카운터를 계수하면서 마이크로컨트롤러(15)에서 히터(14)의 히팅 동작 시간을 제어하고 마이크로컨트롤러(15)에서 제어 신호를 송출하면서 히터(14)의 히팅 동작을 제어하는데, 타이머 또는 카운터가 오동작하는 경우에 대비한 구성 내지는 방법 또는 마이크로컨트롤러(15)의 오동작을 감지하는 구성 내지는 방법이 없으므로 마이크로컨트롤러(15)나 마이크로컨트롤러(15)에 내장된 타이머 또는 카운터가 오동작하는 경우 히터(14)가 과열되어 안전성에 문제가 발생할 가능성이 있다. 또한 대한민국등록특허공보 10-1824765에는 재사용할 수 있는 히팅 요소를 가진 에어로졸-발생 장치에 대해 개시되어 있다. 하지만 상술한 종래기술에서는 히팅 동작에서 히팅 시간의 오류를 감지하거나 마이크로컨트롤러의 오동작을 감지하여 에어로졸-발생 장치의 과열을 방지할 수 있는 구성 및 방법에 대해서는 개시되어 있지 않다. 1 is a cross-sectional view schematically showing a portable aerosol generator according to an embodiment of the prior art.
