The electric heating rod 1403 is fixed in the middle of the heating chamber 1402, and the temperature sensors 1404 are installed on the inner walls of both sides of the heating chamber 1402. A temperature control display screen 11 is installed on the upper part of the emergency breathing machine housing 1, one end of the oxygen tank 8 is connected to the air supply pump 12, the output end of the air supply pump 12 is connected to the air supply pipe 13, the end of the air supply pipe 13 is connected to the heating chamber 1402, and the electric heating rods 1403 in the heating chamber 1402 are evenly distributed.

[0032] Specifically, the air supply pump 12 and the air delivery pipe 13 are used to facilitate the input of oxygen in the oxygen tank 8 into the interior of the heating chamber 1402, and the electric heating rod 1403 is used to facilitate the rapid heating of the air inside the heating chamber 1402, so that this part of the emergency breathing gas can adapt to the temperature of the human body and reduce the discomfort caused by the low temperature to the respiratory tract of the human body. The temperature sensor 1404 is used to facilitate the detection of the air temperature inside the heating chamber 1402 and the temperature can be displayed on the temperature control display screen 11, which is more convenient to use.

[0037] In summary, the working principle:

[0038] First, the oxygen tank 8 is set inside the fixing frame 9 above the support plate 6, so that the fixing frame 9 clamps and limits the oxygen tank 8. At this time, the rubber pad 10 inside the fixing frame 9 can be flexibly fitted with the outer side of the oxygen tank 8 to avoid hard collision and damage to the oxygen tank 8. Then the emergency breathing machine housing 1 can be carried by the handle 4. In this process, the hemispherical rubber block 503 with an arc-shaped structure can play a role of buffering and shock absorption through deformation, and the damper 501 on the lower side of the support plate 6 can filter the vibration, thereby playing a role of shock absorption, so that the oxygen tank 8 is placed more stably, and the damper 501 can be limited by the groove block 502 to suppress the reciprocating motion of the damper 501 itself;

[0039] Secondly, the oxygen in the oxygen tank 8 is input into the heating chamber 1402 through the air supply pump 12 and the air delivery pipe 13, and then the air in the heating chamber 1402 is quickly heated by the evenly distributed electric heating rods 1403, so that this part of the emergency breathing gas can adapt to the human body temperature, reducing the discomfort caused by low temperature to the human respiratory tract. At this time, the air temperature in the heating chamber 1402 can be detected by the temperature sensor 1404 and displayed on the temperature control display screen 11;

[0040] The heated oxygen inside the heating chamber 1402 is then transported to the breathing mask 1504 through the corrugated connecting tube 1503, so that the breathing mask 1504 can be attached to the human mouth and nose for emergency breathing ventilation and rescue. When not in use, the corrugated connecting tube 1503 and the breathing mask 1504 inside the storage chamber 1501 can also be irradiated and sterilized by the ultraviolet disinfection lamp 1502.
