The invention relates to an
air breathing device integrating a head-up display function and a communication function. The
air breathing device comprises a backing tool, an air cylinder tightening belt is arranged on the upper middle portion of the backing tool, and a strap
assembly is arranged on the lower portion of the backing tool. A sending end box of a head-up
display device is arranged at the position, located in the middle of the strap
assembly, of the lower portion of the backing tool, the sending end box comprises a left box body and a right box body, the backing tool is connected with a pressure
reducer which is connected with a pressure
reducer end
medium pressure pipe, a duplex female rapid insert is connected between the pressure
reducer end
medium pressure pipe and the other end of an output line above the right box body, the duplex female rapid insert is in
butt joint with a duplex male rapid insert which is connected with an air supply valve, the receiving display end of the head-up
display device is arranged on the air supply valve, and the air supply valve is connected with a full face
mask; a communication sound amplification device is arranged on the full face
mask; the left box body is connected with the
display device through a cable. The
air breathing device reduces the weight of the communication full face
mask, lines on the chest of a firefighter are simplified, the phenomenon that a hook and a line
pipe intersect when the air
breathing device is used is greatly avoided, the safety is improved, and the air
breathing device is attractive and convenient to use.
