Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, a hybrid closed type circulation breathing apparatus in this embodiment includes a tank 1, an oxygen tank 2 disposed at the bottom of the tank 1, and a multi-way valve 3 fixedly mounted at an output end of the oxygen tank 2, the oxygen tank 2 is bound at the bottom of the tank 1 through a binding band, an inflatable buoyancy bag 6 is disposed at the back of the tank 1, the inflatable buoyancy bag 6 is fixed at the back of the tank 1 in a sticking manner, an air inlet end of the inflatable buoyancy bag 6 is connected to a buoyancy bag inflation valve 5, the other end of the buoyancy bag inflation valve 5 is connected to an output port of the multi-way valve 3 through an air duct 4, the buoyancy bag inflation valve 5 is used to control opening and closing of the air inlet end of the inflatable buoyancy bag 6, when buoyancy is required, the buoyancy bag inflation valve 5 is opened to enable oxygen in the oxygen tank 2 to enter the inflatable buoyancy bag 6, so as to achieve a quick inflation effect, so that buoyancy is provided by the inflatable buoyancy bag inflation valve 6, wherein the buoyancy bag inflation valve 5 in this embodiment is a manual inflation valve, an air outlet end of the inflatable buoyancy bag 6 is connected to an exhaust valve 7, and when buoyancy valve 7 is opened again, the buoyancy bag 6 is manually exhausted.

It should be noted that, in order to avoid the situation that the air vent valve 7 and the buoyancy bag inflation valve 5 are arranged on the back of the box body 1, which is inconvenient for the opening and closing operations of the box body, the lengths of the connecting pipelines between the air vent valve 7 and the buoyancy bag inflation valve 5 as well as the inflation buoyancy bag 6 can be properly prolonged, and the air vent valve 7 and the buoyancy bag inflation valve 5 are conveniently arranged on the two sides of the diver, so that the diver can operate the diver conveniently.

In addition, the multi-way valve 3 in this embodiment is a four-way valve, the other two end ports are further connected with an automatic gas adding valve 8 and an oxygen meter 9 through pipelines, and the oxygen meter 9 is a barometer.

In this embodiment, the inside of box 1 is provided with circulation respiratory device, the top of box 1 is provided with breathing pipe 10, breathing pipe 10 is the one-way pipeline, and breathing pipe 10 is connected with circulation respiratory device. The circulating breathing device comprises a first lung bag connected with one end of the breathing pipeline 10, a second lung bag connected with the other end of the breathing pipeline 10 and adsorbent tanks respectively connected with the first lung bag and the second lung bag, wherein the adsorbent tanks are used for adsorbing carbon dioxide in exhaled air; and can provide mist's mixed apparatus of oxygen supply, it fixes to mix the apparatus of oxygen supply the box outside, mix the apparatus of oxygen supply including the oxygen jar of installing oxygen, install mist's diluent gas jar, and respectively with the oxygen jar with the automatic aeration valve that diluent gas jar links to each other, automatic aeration valve with first lung bag links to each other, and the oxygen jar all sets up in the bottom of box 1 with diluent gas jar.

Specifically, when using this embodiment dive, the human body passes through breathing pipe 10 breathes, when breathing in, the oxygen of second lung bag gets into breathing pipe 10's one end is inhaled by the human body, and during the expiration, the human body is in carbon dioxide and the exhalation of surplus oxygen that produces the metabolism the other end of breathing pipe 10, and because breathing pipe 10 is one-way pipeline, so the gas of exhalation can not get into in the second lung bag, can only get into in the first lung bag, then the process carbon dioxide adsorbent effect in the adsorbent jar adsorbs the carbon dioxide of exhalation gas, and surplus oxygen gets into in the second lung bag, for the human body inhales. So can be so that the oxygen in the expiratory gas by cyclic utilization, avoid extravagant, this embodiment volume can set up very little, because the make full use of oxygen, but can supply the human body to dive for a long time, and owing to pass through breathing pipe 10 breathes, and gas is not discharged in the sea, consequently can not produce the bubble, so be fit for the system of fighting, especially infiltration combat.
