When the operator pulls out the cylindrical T-shaped positioning pin, the limiting effect of the cylindrical T-shaped positioning pin on the regulating cylinder is released. After the regulating cylinder rotates, the ball head disengages from the inlet and outlet grooves. The rotating shaft resets and rotates under the action of the first spring. The rotating knife cuts the surface of the soft partition through the cutting edge and simultaneously cuts the surface of the elastic rope. The catalyst in the soft partition leaks out and chemically reacts with the solid oxygen source in the solid box.

Multiple adjustment cylinders can be operated in sequence to ensure that multiple chemical reactions inside the main shell generate oxygen and perform oxygen supply operations.

[0024] In the present invention, the crushing knife crushes the solid oxygen source so that the crushed solid oxygen source can better react with the catalyst. By providing an inclined surface, the crushed solid oxygen source will approach the soft partition through the inclined surface, reducing the time of contact catalytic reaction. The L-shaped shaft rotates and contacts the inner wall of the arc groove, so that the mounting turntable is forced to rotate.

By setting the shortest distance between the elastic rope 23 and the center axis of the rotating shaft 30 to be less than the distance between the cutting blade 45 and the center axis of the rotating shaft 30, the cutting blade 45 can rotate to cut the surface of the elastic rope 23 to break it.

[0040] As a preferred embodiment of the present application, a plurality of ventilation holes 37 are provided on the surface of the solid box 8 , and a flow regulating valve 5 is fixedly connected to the surface of the oxygen tube 3 .

[0041] By providing a flow regulating valve 5, the discharge amount of oxygen is adjusted, and by providing a plurality of ventilation holes 37, the solid oxygen source in the solid box 8 can react with the catalyst better.

[0043] By providing the indicator light 6 and the buzzer 7 , it is possible to know whether the interior of the main housing 1 is under a safe pressure and has not leaked.

[0044] As a preferred embodiment of the present application, the switch controller 2 is fixedly connected to the surface of the main shell 1 , and a plurality of heat-absorbing anti-slip stickers 44 are fixedly connected to the surface of the main shell 1 .

[0045] By providing the heat-absorbing anti-slip sticker 44, when catalytic heat is released, the heat is absorbed and diffused to reduce the temperature.

[0046] The working principle of the present invention is: Before use, the operator can fix the breathing mask 4 on the user's head by means of the Velcro female sticker 43 and the Velcro child sticker 42. Before supplying oxygen, the operator turns on the switch controller 2, pulls out the cylindrical T-shaped positioning pin 15, releases the limit of the cylindrical T-shaped positioning pin 15 on the adjusting cylinder 18, and then rotates the operating knob 19. The rotation of the operating knob 19 drives the adjusting cylinder 18 to rotate. After the adjusting cylinder 18 rotates, the ball head 26 is disengaged from the inlet and outlet groove 28. At this time, the rotating shaft 30 is reset and rotated under the action of the first spring 29, pulling the connecting rope 13 to be stored in the main body shell 1 while driving the multiple rotating blades 21 and the mounting convex shaft 22 to rotate. The rotating blade 21 cuts the surface of the soft partition 10 through the cutting edge 45, and at the same time cuts the surface of the elastic rope 23. The catalyst in the soft partition 10 leaks out and reacts chemically with the solid oxygen source in the solid box 8 to generate oxygen and release high temperature. The high temperature is absorbed and diffused by the multiple heat-absorbing anti-slip stickers 44 to cool down. When the rotating shaft 30 rotates, it drives the multiple L-shaped shafts 50 to rotate. The L-shaped shafts 50 rotate and enter the arc groove 52, so that the installation turntable 51 is forced to rotate. Under the drive shaft 48, the installation turntable 51 rotates and drives the plastic shovel 49 to rotate. The plastic shovel 49 rotates to scoop out the catalyst in the broken soft partition 10, so that it quickly contacts the solid oxygen source in the solid box 8 to chemically react and generate oxygen. When the elastic rope 23 breaks, the rotating shaft 33 rotates and resets under the action of the second clockwork 32. At this time, the rotating shaft 33 drives the cam 25 to rotate. The cam 25 rotates and contacts the lower surface of the solid box 8. The rotation drives the solid box 8 to shake under the action of its own gravity, so that the positioning shaft 39 and the limit plate 38 rotate. The shaking solid oxygen source in the solid box 8 contacts the crushing knife 46, so that the crushed solid oxygen source can better react with the catalyst to generate oxygen. The crushed solid oxygen source will approach the soft partition 10 through the inclined surface 47, reducing the contact catalytic reaction time. The generated oxygen is filtered through the filter 11, then enters the oxygen tube 3 and is inhaled by the operator wearing the breathing mask 4. The flow regulating valve 5 can be adjusted to control the amount of oxygen entering the breathing mask 4. The multiple regulating cylinders 18 can be operated in sequence to ensure that multiple chemical reactions inside the main shell 1 produce oxygen and perform oxygen supply operations. With the above structure, the main shell 1 has a small overall volume and is easy to carry. It can produce oxygen through multiple chemical reactions to meet immediate needs in a field environment.
