Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Refer to Figures 1 - 5 , an embodiment provided by the present invention: A chemical oxygen self-rescue breathing apparatus includes an upper interface component 1, a lower interface component 2, a one-way breathing valve interface 3, a chemical oxygen tank 4, and a gas storage bag 5; the one-way breathing valve interface 3 includes a breathing valve socket component 303 and a connection component 308, and the breathing valve socket component 303 includes a medicine canister lock ring 306, a socket flat sealing ring 305, a ventilation hole 307, and a breathing diaphragm 302;

[0024] The chemical oxygen tank 4 includes an upper net plate 404 connected to a partition 405, and the partition 405 is connected to a lower net plate 407.

[0025] The connection component 308 includes a gas storage bag lock ring 301, a first socket O-ring 304, and a threaded interface 309.

[0026] The lower interface component 2 is connected to the upper interface component 1 in a snap-fit form, and the lower part of the lower interface component 2 is connected to the one-way breathing valve interface 3 by a thread.

[0027] Ventilation holes 307 are provided in four directions of the breathing valve socket component 303, breathing diaphragms 302 are provided corresponding to the ventilation holes 307, the breathing diaphragms 302 are arranged inside the breathing valve socket component 303, a socket flat sealing ring 305 is arranged on the lower side of the ventilation hole 307, and a medicine canister lock ring 306 is arranged at the bottom of the breathing valve socket component 303.

[0028] The connecting component 308 is arranged above the breathing valve socket component 303 through a threaded connection. A gas storage bag lock ring 301 is arranged at the connection, a threaded interface 309 is arranged above the gas storage bag lock ring 301, and a first socket O-ring 304 is arranged above the threaded interface 309.

[0029] The lower interface component 2 includes a connection base 204. A socket 201 is arranged above the connection base 204. A second socket O-ring 202 is arranged on the socket 201, and a seal ring 203 is arranged above the second socket O-ring 202.

[0030] A medicine tank interface 401 is arranged at the top of the chemical oxygen tank 4. A medicine tank opening 402 is arranged below the medicine tank interface 401. A plurality of reaction agents 406 are arranged on the surface of the partition 405, and the reaction agent is composed of potassium superoxide; a sealing plug 410 and a quick start device 409 are arranged at the bottom of the chemical oxygen tank 4, and a pull rod 411 is arranged at the bottom of the quick start device 409.

[0031] A sponge spacer 403 is arranged on the upper surface of the upper mesh plate 404, and a filter paper is arranged on the lower surface; a filter paper is arranged on the upper surface of the lower mesh plate 407, and a sponge spacer 408 of the lower mesh plate is arranged on the lower surface of the lower mesh plate 407. Among them, the upper mesh plate 404, the sponge spacer 403 of the upper mesh plate, the lower mesh plate 407, and the sponge spacer 408 of the lower mesh plate are all in a hollow form, which is a structure convenient for gas passage.

[0032] A connection buckle 501 is arranged on one side of the gas storage bag 5, and the connection buckle 501 is respectively connected to the sealing plug 410 and the pull rod 411 through ropes.

[0033] Working principle: When the respirator is taken out of the box and the folded respirator is unfolded, the connection buckle 501 of the gas storage bag 5 pulls out the pull rod 411 from the quick start device 409, and at the same time pulls out the sealing plug. The compressed oxygen in the quick start device 409 is discharged into the gas storage bag 5, which can quickly provide oxygen for the user.

[0034] The upper interface component 1, the lower interface component 2, and the one-way breathing valve interface 3 are combined together. The upper end of the upper interface component 1 is connected to the face mask, the connecting component 308 is connected to the air storage bag 5, and the medicine tank lock ring 306 is connected to the chemical oxygen tank 4. When the gas exhaled by the human body enters the chemical oxygen tank 4, the medicine in the tank inhales dioxide and moisture and undergoes a chemical reaction to generate a sufficient amount of oxygen. Most of the oxygen will enter the air storage bag 5 through the opening at the bottom of the chemical oxygen tank 4 due to the pressure difference. When the human body inhales, due to the pressure difference, there is a gap between the breathing diaphragm 302 and the inner wall of the breathing valve socket component 303, so that the oxygen in the air storage bag 5 enters the inside of the breathing valve socket component 303 through the ventilation hole 307. The suction conduit device is cancelled at the top of the chemical oxygen tank 4 of this device. When the human body exhales, the breathing diaphragm 302 adheres to the inner wall, so that the exhaled gas enters the chemical oxygen tank 4 and will not discharge the waste gas into the air storage bag 5 through the suction conduit. This makes the exhalation smoother, the oxygen purer, and the breathing more labor-saving. The exhaled gas continues to react with the medicine in the chemical oxygen tank 4, which can provide oxygen supply for more than 30 minutes. In addition, the oxygen channel does not pass through the center of the chemical oxygen tank 4, and the temperature of the oxygen will also decrease a little.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
