Abstract

The invention relates to underwater breathing apparatus. The underwater breathing apparatus comprises a control unit, an energy system, an evaporator, a liquid storage chamber and an connector which are connected in sequence, wherein the control unit is mainly used for controlling opening and closing of the whole apparatus and adjusting the release quantity of neutralization reagents; the energy system is mainly used for providing reliable electric power supply for a whole system and heating the evaporator; the evaporator is mainly used for heating the liquid storage chamber so that chemical reagents in the liquid storage chamber can be volatilized out to neutralize alkalinity of soda lime; the liquid storage chamber is mainly used for storing the proper quantity of moderate neutralization reagents; the connector is used for connecting an adaptor to a main system. The underwater breathing apparatus eliminates erosion of the soda lime to the respiratory tract of a diver so that the diver can work underwater comfortably. A special connector with the corresponding shape can be manufactured according to the specific model of non-foaming cyclic underwater breathing apparatus, and the diver can replace the connector with one hand, so the underwater breathing apparatus is convenient to adjust and use.

Description

technical field [0001] The invention relates to an underwater respirator, which belongs to the technical field of diving equipment. Background technique [0002] The 21st century is the century for human beings to develop and utilize the ocean. With the rapid development of urbanization and the steady increase of people's income, urban construction, fish farming, marine production and high-end entertainment activities have made diving, which was less accessible before The activities gradually come into people's field of vision. In addition, various fields such as engineering construction and crisis rescue urgently need the participation of divers. At present, the modes for divers to breathe underwater include: (1) utilizing pipelines or snorkels to supply air; (2) carrying oxygen cylinders on their backs. (3) Bubble-free circulating underwater breathing apparatus. [0003] As far as carrying oxygen cylinders for diving breathing is concerned, the common civilian diving ox...

AI Technical Summary

Problems solved by technology

(2) Low utilization rate of oxygen

(3) The exhaust gas exhaled by divers will form a large number of bubbles in the water, which will not only interfere with the diver's vision, affect underwater operations, but also expose the diver's position

But soda lime is an alkaline substance, and the high concentration of water vapor in the exhaust gas exhaled by personnel will carry soda lime particles to form alkaline vapor, which will have a serious ablation effect on the respiratory tract of personnel when inhaled again. Having to float up due to burning pain in the respiratory tract is not conducive to the continuity of underwater operations, and it will also cause damage to the diver's body
