Air breathing device integrating head-up display function and communication function

The technical field of

[0001] the invention claims an integrated with a horizontally viewing display and communication function of the air breathing apparatus which belongs to fire it back to the technical field of.

Background technology

[0002] positive pressure air breathing apparatus as respiratory protection device is widely applied to fire and rescue metallurgy chemical industry watercraft and army and each other field. Positive pressure air breathing apparatus is composed of air bottle pressure reducer assembly of gas supplying valve and back cover board assembly. When using the high pressure air bottle is filled in the 30mpa the compressed air and then the high pressure gas bottle and air breathing apparatus of the reducer is connected with the; When the air bottle valve is opened the air in the bottle the compressed air enters pressure reducer and then it is composed of one-stage pressure reducing at the middle pressure pipe and the air supply valve to carry out secondary decompressing finally entering face mask for using the respiratory using.

[0003] in existing technology the electronic air breathing apparatus field it mainly indicates with horizontally viewing display function of respirator and horizontally viewing display device can be divided into the wire is connected with the wireless connected with two ways of the pressure sensor sending terminal and receiving display end is connected with the wire connection mode a plurality of the screw thread connection when the air supply valve and decompressor the middle of the quick joint is connected with screw thread it adopts the aviation connector and connected with the comparison such as wasting time and it is not convenient to fireman operation.

[0004] at the same time the electronic air breathing apparatus field of communication device is a important content electronic air respirator it always uses the communication of sound amplifying function of the whole surface of the cover of the voice communication on the surface of the cover can not set with battery storehouse is used for supplying power and the communication surface cover is set on the outside of ptt and interphone is connected with the connecting head so that the communication surface cover the weight of the increasing and the user prethoracic and the original air supply valve in the middle of the pressure rubber tube is also added a communication line in the actual use and it is easy to be winding and hook so it affects the user the safety of the present air supply valve and full face mask connection structure is simple fast gas circuit insert structure a simple structure it can satisfy the requirement which is heavy it is not convenient for the external communication thereby only need to be improved.

[0005] the present electronic air breathing apparatus of the position of the back of the electronic signal sending end structure of this invention uses the single box structure of a adopt the ordinary dry battery power supply is not convenient to change is wasted seriously and the use of lithium battery but can not convenient to tear down charging; It does not have a is directly can be connected with interphone of ptt and; To the wiring is not neat to the use to cause inconvenience to the left and right are not symmetrical and beautiful appearance is not currently used is a box structure only has a position calling lamp and the wounded soldier falling is always * the shielding gas bottle is easy to be formed only in a side seen from it is not convenient for rescue personnel of the searching discovering and.
