Mine safety helmet with escaping navigation function

The utility model aims at providing a mine safety helmet with an escaping navigation function, and the mine safety helmet comprises a safety helmet shell, a mine lamp, a metal iron sheet for fixing the mine lamp, a head fixing helmet band, a methane detection sensor, a breathing port, a carbon oxide detection sensor, a lithium battery, a navigation positioning device, a safety helmet liner, vibration sensors, a loudspeaker, a microphone, a loudspeaker sound transmitting port, a talkback button, a charging and universal serial bus (USB) interface, an emergent escaping button and a mine well map display screen. When a safety accident happens in the pit or when the methane detection sensor and the carbon oxide detection sensor detects that the methane or the carbon oxide is out of limit, the loudspeaker issues an alarm automatically so as to remind of starting an escaping navigation function. When the emergency escaping button is pressed down, eight vibration sensors in different directions prompts a current escaping direction through vibration according to an optimum escaping way provided by the navigation position device, the current position and the escaping way of the miner can be displayed on the map display screen, and the escaping way is broadcasted in a voice way through the loudspeaker.
