Abstract

본 발명은 자동차의 실내 공기를 감지하여 산소결핍 정도가 심화된 경우에는 이것을 경보하는 경보장치에 관한 것으로서, 종래에는 이러한 수단이 자동차 내에 구비되어져 있지 않아 밀폐된 자동차 내에서 운전자가 산호결핍으로 쉽게 피로를 느끼거나 두통이 발생하는 등의 현상을 적극적으로 방지하지 못하고 있으므로 바람직한 것이 못 되었다.The present invention relates to an alarm device that detects indoor air of an automobile and alerts it when oxygen deficiency is intensified. Conventionally, such a means is not provided in an automobile, and thus, the driver easily fatigues due to coral deficiency in a closed vehicle. It is not desirable because it does not actively prevent symptoms such as feeling or headaches.

본 발명의 종래의 이러한 문제점을 개선할 수 있도록 자동차의 실내에 설치되어져서 공기를 감지하는 센서부(11)와, 이 센서부(11)의 출력측에 연결되어져서 센서부(11)를 구동하는 센서구동부(12)와, 이 센서구동부(12)의 출력측에 연결되어져서 일정시간 타이머 동작하는 타이머부(13)와, 이 타이머부(13)의 출력측에 연결되어져서 소리음이나 경보표시기등을 동작시키는 경보부(14)로 이뤄져 있는 구성을 특징으로 자동차 내의 산소결핍 경보장치를 제공하는데 있다.In order to improve such a problem of the related art of the present invention, the sensor unit 11 installed in the interior of a vehicle and detecting air is connected to the output side of the sensor unit 11 to drive the sensor unit 11. It is connected to the sensor driver 12, an output side of the sensor driver 12, and is connected to an output side of the timer unit 13 to operate a timer for a predetermined time and to operate a sound sound or an alarm indicator. To provide an oxygen deficiency warning device in a vehicle characterized by the configuration consisting of a warning unit 14 to.
