Therefore, when a human body is in outdoor activities in a plateau environment, the protective oxygen supply equipment carried with the human body becomes a necessary choice. The human body physiological hygiene research shows that: taking sea level breathing pure oxygen as an example, only 4-5% of oxygen in volume participates in breathing exchange in the breathing process of a human body, and more than 95% of oxygen in volume is discharged into the atmosphere along with exhaled air. If we try to collect the main components of the exhaled breath of human body, namely residual oxygen, nitrogen, carbon dioxide and water vapor, purify and remove the carbon dioxide by a chemical method, the residual oxygen which does not participate in lung exchange is supplied to the human body for breathing cycle, and the consumed partial volume of oxygen is supplemented at the same time, the utilization rate of the oxygen can be greatly improved, thereby forming a closed breathing loop system and achieving the aim of the exhaled breath regeneration cycle utilization.
