Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0014] See also Figure 1-2 , this embodiment provides a technical solution: a new shell structure isolated chemical oxygen self-rescuer, including an inner shell 1, an air bag 10, an air guide tube 14, a buckle assembly and a mounting assembly;

[0015] Outer shells 13 are installed on both sides of the inner shell 1, and mounting components are provided on the outside of the two outer shells 13. A cover plate 3 is installed on the rear side of the inner shell 1 through a pin shaft. The cover plate 3 and the outer shell 13 are connected by a snap assembly. An oxygen candle 16 is installed inside the inner shell 1, and a baffle 17 is installed inside the inner shell 1. The oxygen candle 16 is located in the space enclosed by the baffle 17 and the left side wall of the inner shell 1.

[0016] When in use, the isolated chemical oxygen self-rescuer is carried on the body through the installation component, and the cover 3 is opened through the snap assembly. Since the airbag 10 is stuffed into the outer shell 13 on both sides, the size of the isolated chemical oxygen self-rescuer can be reduced, making it more convenient for workers to use. Then the airbag 10 is taken out from the outer shell 13 on both sides, the headband 6 is tied to the head, and the mouthpiece plug 5 is stuffed into the mouth. The initial oxygen generation is completed by the oxygen candle 16, and the worker absorbs the oxygen transported to the airbag 10 by the oxygen candle 16 through the mouthpiece plug 5. When the worker exhales carbon dioxide gas, the carbon dioxide gas is transported to the lower trachea 20 through the breathing telescopic hose 12 and the breathing valve 15. The breathing valve 15 is a two-way single-vent valve. When the worker inhales, the interface of the breathing valve 15 connected to the lower trachea 20 is closed and the air is The interface of the breathing valve 15 connected to the bag 10 is opened. When the worker exhales, the interface of the breathing valve 15 connected to the airbag 10 is closed and the interface of the breathing valve 15 connected to the lower trachea 20 is opened. The carbon dioxide gas entering the lower trachea 20 is passed into the air chamber. Under the action of the multiple air holes 18 uniformly arranged on the support plate 19, the carbon dioxide gas uniformly enters the space where the oxygen-generating material is located, thereby increasing the mixing reaction effect of the oxygen-generating material and the carbon dioxide gas, and thus making the oxygen entering the airbag 10 sufficient. An exhaust valve is provided on the airbag 10. When there is excess oxygen in the airbag 10, the excess oxygen is automatically discharged through the exhaust valve. Therefore, the utility model is not only convenient for workers to use, increases the practicality of the chemical oxygen self-rescuer, but also effectively ensures the sufficiency of oxygen production to improve the safety of workers.

[0018] The mounting assembly includes a first telescopic belt 9 mounted on the outer end of the left outer shell 13, a second telescopic belt mounted on the outer end of the right outer shell 13, a mounting block 8 mounted on the outer end of each of the first and second telescopic belts, a second clamping block 7 mounted on the outer side of the left mounting block 8, and a second clamping slot provided on the outer side of the right mounting block 8, the second clamping block 7 and the second clamping slot being connected by a snap. The first telescopic belt 9, the second telescopic belt, the second clamping block 7 and the second clamping slot allow the inner shell 1 and the outer shell 13 to be carried around, further enhancing the practicality of the chemical oxygen self-rescuer.

[0019] The working principle of the novel shell structure isolated chemical oxygen self-rescuer provided by the present invention is as follows: when in use, the isolated chemical oxygen self-rescuer is carried on the body through the installation component, and the cover 3 is opened through the snap assembly. Since the air bag 10 is stuffed into the outer shell 13 on both sides, the size of the isolated chemical oxygen self-rescuer can be reduced, so that it is more convenient for workers to use. Then the air bag 10 is taken out from the outer shell 13 on both sides, the headband 6 is tied to the head, and the mouthpiece plug 5 is stuffed into the mouth. The initial oxygen generation is completed by the oxygen candle 16. The worker absorbs the oxygen transported to the air bag 10 by the oxygen candle 16 through the mouthpiece plug 5. When the worker exhales carbon dioxide gas, the carbon dioxide gas is transported to the lower trachea 20 through the breathing telescopic hose 12 and the breathing valve 15. The breathing valve 15 is a two-way single-vent valve. When the worker inhales, it is connected to the lower trachea 20. The breathing valve 15 interface connected to the airbag 10 is closed, and the breathing valve 15 interface connected to the airbag 10 is opened. When the worker exhales, the breathing valve 15 interface connected to the airbag 10 is closed, and the breathing valve 15 interface connected to the lower trachea 20 is opened. Carbon dioxide gas entering the lower trachea 20 is passed into the air chamber. Under the action of the multiple air holes 18 uniformly arranged on the support plate 19, the carbon dioxide gas evenly enters the space where the oxygen-generating agent is located, thereby increasing the mixing reaction effect of the oxygen-generating agent and carbon dioxide gas, thereby ensuring sufficient oxygen entering the airbag 10. The airbag 10 is equipped with an exhaust valve. When the oxygen in the airbag 10 is excessive, the exhaust valve automatically removes the excess oxygen. Therefore, this utility model is not only convenient for workers to use and increases the practicality of the chemical oxygen self-rescuer, but also effectively ensures the sufficiency of oxygen production, thereby improving the safety of workers. The cover plate 3 can be installed and removed through the first clamping block 2 and the first clamping slot 11, making it convenient for workers to use. The inner shell 1 and the outer shell 13 can be carried around by means of the first telescopic belt 9, the second telescopic belt, the second clamping block 7 and the second clamping slot, thereby further improving the practicality of the chemical oxygen self-rescuer.
