DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Reference Figure 1-Figure 5The utility model provides an embodiment: a chemical oxygen self-rescue respirator connection port, including an upper interface component 1, a lower interface component 2, and a one-way breathing valve interface 3; the one-way breathing valve interface 3 includes a breathing valve socket component 303 and a connecting component 308, the suction valve socket component 303 includes a medicine tank locking ring 306, a socket plane sealing ring 305, a vent 307, and a breathing diaphragm 302; the connecting component 308 includes an air storage bag locking ring 301, a first socket O-ring 304, and a threaded interface 309.

[0022] The lower interface component 2 is connected to the upper interface component 1 in a snap-fit ​​manner, and the lower part of the lower interface component 2 is connected to the one-way breathing valve interface 3 through threads.

[0023] Ventilation holes 307 are arranged on four directions of the breathing valve socket assembly 303, and breathing diaphragms 302 are arranged corresponding to the vent holes 307. The breathing diaphragm 302 is arranged inside the breathing valve socket assembly 303, and a socket plane sealing ring 305 is arranged on the lower side of the vent hole 307. A medicine tank locking ring 306 is arranged at the bottom of the breathing valve socket assembly 303.

[0024] The connection component 308 is arranged above the breathing valve socket component 303 through a threaded connection, an air storage bag locking ring 301 is arranged at the connection, a threaded interface 309 is arranged above the air storage bag locking ring 301, and a first socket O-ring 304 is arranged above the threaded interface 309.

[0025] The lower interface assembly 2 includes a connection base 204 , a socket 201 is provided above the connection base 204 , a second socket O-type sealing ring 202 is provided on the socket 201 , and a sealing ring 203 is provided above the second socket O-type sealing ring 202 .

[0026] Working principle: 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 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 reacts chemically to generate a sufficient amount of oxygen. Most of the oxygen will enter the air storage bag 5 through the bottom opening 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 vent 307. When the human body exhales, the breathing diaphragm 302 sticks to the inner wall, so that the exhaled gas enters the chemical oxygen tank 4, which makes the exhalation smoother and more labor-saving.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
