Description

Portable multi-source intelligent oxygen production and supply respirator

Technical Field

The invention relates to the field of oxygen production breathing machines, in particular to a portable multi-source intelligent oxygen production and supply breathing instrument.

Background

Oxygen is one of the important factors for human body to maintain life, and oxygen safety is more and more valued by people with the more frequent communication among people in the east and west China and the more and more aggravation of the aging of the population in China. At present, people mostly adopt portable oxygen inhalation instruments such as filling type oxygen bottles, disposable oxygen inhalation bags or household oxygenerators to meet the daily oxygen demand. However, both the filling type oxygen cylinder and the disposable oxygen inhalation bag have no self-oxygen generating function, and can not supply oxygen continuously, so that the capability of the filling type oxygen cylinder and the disposable oxygen inhalation bag for handling emergencies is greatly limited. Most of the household oxygen generators adopt a molecular sieve filtration method to separate oxygen in air, and the oxygen concentration is increased for use. Although the household oxygen-making and oxygen-inhaling instrument can relieve the problem that a filling type oxygen bottle and a disposable oxygen-inhaling bag cannot be used at any time, the oxygen-making capacity of the household oxygen-making and oxygen-inhaling instrument depends heavily on an electric power system and the concentration of ambient air, so that the use of the household oxygen-making and oxygen-inhaling instrument in areas where oxygen supply is urgently needed, such as non-power supply, highland with thin air, anaerobic environment and the like, is directly restricted.

The oxygen production by decomposing water essentially solves the problem that oxygen supply depends on the concentration of peripheral oxygen. The solar cell assists in decomposing water to prepare oxygen, and photo-generated holes generated by sunlight excitation can be used for oxidizing water molecules, so that pure oxygen is obtained. In this case, the oxygen acquisition depends only on sunlight and water. It is well known that the harvesting of sunlight is not limited by the region, and that water can be easily harvested from nature. The utilization of solar energy to convert water into oxygen offers the possibility of obtaining oxygen without time, space and environmental restrictions and shows great potential for application. Unfortunately, no related product or patent is currently on the market. Therefore, based on the solar cell assisted water decomposition oxygen production device, the oxygen production and supply respirator which can be taken at will and continuously supplied with oxygen at any time and is not limited by regions is developed, and the respirator has important practical application value.
