In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

如图1-图14所示，本发明提出一种纯氧型密闭式循环呼吸系统，所述纯氧型密闭式循环呼吸系统包括：As shown in FIG. 1-FIG. 14, the present invention proposes a pure oxygen type closed circulatory breathing system, and the pure oxygen type closed circulatory breathing system includes:

设有呼吸管道11的箱体1，所述呼吸管道11为单向管道；Thebox body 1 is provided with abreathing pipe 11, and thebreathing pipe 11 is a one-way pipe;

能够将呼出气体循环利用的循环呼吸装置,所述循环呼吸装置固定在所述箱体1内，所述循环呼吸装置包括与所述呼吸管道11一端相连的第一肺袋6，与所述呼吸管道11另一端相连的第二肺袋，及分别与所述第一肺袋6和所述第二肺袋相连接的吸附剂罐8，所述吸附剂罐8用于吸附呼出气体中的二氧化碳；以及A circulatory breathing device capable of recycling exhaled gas, the circulatory breathing device is fixed in thebox body 1, and the circulatory breathing device includes afirst lung bag 6 connected to one end of thebreathing pipe 11, which is connected to thebreathing tube 11. A second lung bag connected to the other end of thepipe 11, and anadsorbent tank 8 connected to thefirst lung bag 6 and the second lung bag respectively, theadsorbent tank 8 is used to adsorb carbon dioxide in exhaled air ;as well as

能够提供纯氧的纯氧装置，所述纯氧装置固定在所述箱体1外侧，所述纯氧装置包括装设有氧气的氧气罐2，及与所述氧气罐2相连的自动加气阀5，所述自动加气阀5与所述第一肺袋6相连。A pure oxygen device capable of providing pure oxygen, the pure oxygen device is fixed on the outside of thebox 1, and the pure oxygen device includes anoxygen tank 2 equipped with oxygen, and an automatic gas filling connected to theoxygen tank 2 Thevalve 5 is connected with thefirst lung bag 6 .

具体的，使用本实施例潜水时，人体通过所述呼吸管道11呼吸，吸气时，所述第二肺袋的氧气进入所述呼吸管道11的一端并被人体吸入，呼气时，人体将代谢产生的二氧化碳和剩余氧气呼出在所述呼吸管道11的另一端，且由于所述呼吸管道11为单向管道，因此呼出的气体不能进入所述第二肺袋内，只能进入所述第一肺袋6内，然后经过所述吸附剂罐8内的二氧化碳吸附剂作用，将呼出气体的二氧化碳吸附，剩余的氧气进入所述第二肺袋内，供人体吸入。这样可以使得呼出气体内的氧气被循环利用，避免浪费，本实施例体积可以设置的很小，由于氧气的充分利用，却可以供人体长时间潜水，且由于是通过所述呼吸管道11呼吸，气体不排出在海里，因此不会产生气泡，所以本实施例适合作战系统，尤其是渗透作战。Specifically, when diving using this embodiment, the human body breathes through thebreathing pipe 11. When inhaling, the oxygen in the second lung bag enters one end of thebreathing pipe 11 and is inhaled by the human body. When exhaling, the human body will Carbon dioxide and residual oxygen produced by metabolism are exhaled at the other end of thebreathing pipe 11, and because thebreathing pipe 11 is a one-way pipe, the exhaled gas cannot enter the second lung bag, but can only enter the second lung bag. In thefirst lung bag 6, the carbon dioxide adsorbent in theadsorbent tank 8 adsorbs the carbon dioxide in the exhaled air, and the remaining oxygen enters the second lung bag for inhalation by the human body. In this way, the oxygen in the exhaled gas can be recycled to avoid waste. The volume of this embodiment can be set to be very small. Due to the full utilization of oxygen, it can be used for diving for a long time by the human body.
