Problems solved by technology

In the past open scuba diving, the air was directly exhausted into the sea after the oxygen metabolism of the human body, and only about 5-6% of the oxygen in the gas was used in the oxygen metabolism process, and the rest of the oxygen was discharged together with the inert gas, which resulted in Gas waste during diving, shortening dive time

Abstract

The invention discloses a mixed type closed circulating breathing system, which comprises a box body provided with a breathing pipeline; a circulating breathing device is fixed in the box body and comprises a first lung bag connected with one end of the breathing pipeline, a second lung bag connected with the other end of the breathing pipeline and an adsorbent tank connected with the first lung bag and the second lung bag; and the adsorbent tank is used for adsorbing carbon dioxide in exhaled gas; a mixed oxygen supply device which comprises an oxygen tank filled with oxygen, a diluted gas tank filled with mixed gas and an automatic gas adding valve connected with the oxygen tank and the diluted gas tank respectively, and the automatic gas adding valve is connected with the first lung bag. By the adoption of the design, oxygen can be recycled, long-time deep diving can be achieved during use, and cost is saved.

Description

technical field [0001] The invention relates to the field of diving, in particular to a hybrid closed circuit breathing system. Background technique [0002] Closed rebreathing system, referred to as CCR, is a breathing device used in diving. In the past open scuba diving, the air was directly exhausted into the sea after the oxygen metabolism of the human body, and only about 5-6% of the oxygen in the gas was used in the oxygen metabolism process, and the rest of the oxygen was discharged together with the inert gas, which resulted in Gas is wasted while diving, shortening dive time. When people dive, a key factor that limits their diving depth is the ratio of oxygen. If you want to dive deeper, you need to use a gas with a lower ratio of oxygen, such as a mixed gas containing an inert gas. [0003] Therefore, there is an urgent need to design a hybrid closed-circuit breathing system that can solve the above-mentioned one or more problems. Contents of the invention [...
