Description
Technical Field
The invention relates to the field of underwater respirators, in particular to an underwater free breathing system.
Background
As the living standard increases, more and more people enjoy diving sports, so scuba should be born in order to meet the needs of people. The existing underwater respirators mainly comprise two types, namely a diving mask with a breathing tube when the underwater respirator is used for shallow diving (generally called floating or swimming within 0.5 m), wherein the breathing tube has a limited length and can only be used for short diving and can not be used for breathing in water for a long time. When diving is deeper (generally 4-5 m), pumping air is generally adopted or an artificial oxygen bottle and breathing adjusting equipment are used, the overall equipment cost is extremely high, and the device is not suitable for ordinary people. Therefore, a floating underwater respiratory system has been developed, in which an air intake pipe is arranged on the water surface through a floating object, or is connected with a mouthpiece through an air pipe, and the air intake pipe is used for sucking air from the mouth and the nasal cavity is used for directly exhausting the waste gas of the human body in the water. The air inlet of the floater is too close to the water surface, water is easy to flow backward into the air pipeline due to the fact that waves are generated on the water surface, natural air is prevented from entering the air inlet pipeline, or water choking is caused to underwater personnel once the natural air flows back into the breathing mask, and life is very likely to be directly threatened; and because the waste gas exhaled by the human body is not subjected to supercharging treatment, accumulated water is easy to flow backward in the exhaust pipeline, the waste water stays in the ventilation chamber, cannot be thoroughly discharged into the atmosphere, and flows back into the breathing mask, so that the waste gas exhausted by the underwater personnel is repeatedly inhaled, and the waste gas is extremely easy to syncope shock due to poisoning. This is extremely dangerous under water.
The former device is viewed reversely, and a plurality of problems exist as well: when diving to a certain depth, the mouth of the relevant person is occupied through mouth-biting training and sucking, and the person does not need to master the normal mode of nose sucking by using the nose, so that the person can master the person through corresponding full training. Furthermore, the nasal cavity is used for directly discharging the waste into the water, and bubbles are generated in the water, so that the waterproof design is too simple, only one waterproof cap is used, only one waterproof treatment is carried out, when the wave is too large, the water easily enters the air guide pipeline and the breathing cover, and even though the mouth breathes, the underwater personnel can easily choke the water. And because water flows backward and enters the air guide pipeline to cause accumulated water, even if the water does not enter the respiratory mask, because the water has a blocking effect on external air, underwater personnel still cannot absorb the external air above the water surface, so that the personnel cannot dive for a long time, the water still needs to float out of the water surface to exchange air, and the preset effect of the device is not exerted practically.

One end of the second air inlet pipe 52 is detachably connected to the side wall of the first air inlet pipe 51. The included angle between the second air inlet pipe 52 and the first air inlet pipe 51 is an upward acute angle of 45 degrees, and the communication point between the second air inlet pipe 52 and the first air inlet pipe 51 is higher than the height of the floating air bag 4, so that the second air inlet pipe cannot be immersed in water. The first air inlet pipe 51 is an elbow formed by injection molding with a connecting pipe fitting at one time, so that water on the water surface is prevented from entering the air inlet pipeline, and even if the water enters the first air inlet pipe, the water directly returns to the water surface through the floating frame due to the fact that the first air inlet pipe is communicated with the branch pipe of the floating frame. The second air inlet pipe is upward and is 45-degree included angle, so that water is further effectively prevented from entering the second air inlet pipe.
