Currently, the breathing self-rescuers on the market are generally heavy in quality and cumbersome to use and operate. In case of emergencies, wearers may encounter situations such as not knowing how to use them, not wearing them in time, or the nose clips falling off, resulting in carbon monoxide poisoning. The existing isolated compressed oxygen self-rescuers weigh at least 1.6 kg. Workers need to wear them for a long time when going down the well, which increases the labor load of the workers. Wearing them for a long time will make the body more tired. The existing chemical oxygen self-rescuers also have problems such as large overall weight, cumbersome operation, a burning sensation of oxygen, which can cause breathing discomfort and is not conducive to improving the wearing enthusiasm of workers.

[0003] How to design a lightweight isolated compressed oxygen self-rescuer with a shell that is convenient to open, an oxygen valve group that is convenient to open, an overall lightweight design, convenient to wear, simple and easy to operate, and effectively guaranteeing the personal safety of underground workers is a technical problem that needs to be solved in the prior art.

The compressed oxygen cylinder is arranged at the bottom of the inner cavity of the lower shell, the control valve group is arranged at the upper end of the compressed oxygen cylinder, the dial is located on one side of the top of the compressed oxygen cylinder, the pressure gauge is located directly in front of the control valve group, the pressure compensation plate is arranged on the same side as the control valve group, the carbon dioxide adsorption chamber is arranged in parallel with the compressed oxygen cylinder at the bottom of the inner cavity of the lower shell, and a carbon dioxide adsorbent and an intake pipe are arranged in the carbon dioxide adsorption chamber. The intake pipe is connected to the outlet pipe built in the oxygen mask to adsorb the carbon dioxide exhaled in the oxygen mask through the outlet pipe and the intake pipe into the carbon dioxide adsorption chamber and reduce and restore part of the oxygen into the oxygen mask.

[0006] As a further optimized solution for the above-mentioned lightweight isolated compressed oxygen self-rescuer, the opening mechanism includes two fixed hooks at the front and rear, an opening buckle, a bandage, and a pull wire. The fixed hooks are in a J-shaped structure, and the hook ends of the two fixed hooks are clamped on the buckle. The opening buckle is arranged above the fixed hooks. The front and rear ends of the bandage are respectively fixed to the upper end of the opening buckle and the rear fixed hook. By unclamping the opening buckle, the bandage can be fully opened to release the restraint of the bandage on the upper cover.
