GAS DETECTION ALARM APPARATUS FOR FIREFIGHTER

摘要

The present invention relates to a gas detection alarm apparatus for a firefighter, capable of detecting various harmful gases by ingredients and being carried more easily. The gas detection alarm apparatus for a firefighter comprises a main body, which can be inserted or attached to a pocket, and a cover. The main body houses a chargeable battery supplying power, a gas pump drawing and discharging external gas, and a PCB. The PCB includes a plurality of sensors detecting introduced gas by ingredients and generating a predetermined electrical signal when a concentration is out of a set range; an MCU controlling an electrical signal generated by the sensor; and a Bluetooth module transceiving a wireless signal to turn on an LED light and generate vibration and buzzer alarm by an external device according to a control signal of the MCU. The gas pump is located under the PCB, and a connector fixture to which a connector connected with a hose for drawing or discharging gas is detachably coupled is provided under the gas pump (11). The gas detection alarm apparatus for a firefighter can allow a user to be quickly evacuated by allowing a plurality of sensors to detect various harmful gases by ingredients and generating alarm or vibration when a signal is out of a set range, thereby more safely handling an environment of harmful gas. Also, the gas detection alarm apparatus for a firefighter can be more easily carried and used by being inserted or attached to a pocket of a user.;COPYRIGHT KIPO 2017
