Description
Technical Field
The invention relates to portable oxygen generation equipment, in particular to a wearable oxygen generation garment, which is mainly used for oxygen absorption people.
Background
The plateau area is thin in air, the atmospheric pressure and the oxygen partial pressure are reduced, the alveolar air and the arterial oxygen partial pressure are correspondingly reduced, the gradient difference of the oxygen partial pressure between capillary blood and cell mitochondria is reduced, and oxygen deficiency is caused.
In order to solve the oxygen inhalation problem of plateau people and maintain the health of the plateau people, at present, various oxygen generating and supplying devices can provide oxygen at a fixed place, but for mobile people, the conventional oxygen supplying devices mainly comprise an oxygen bag, a small oxygen bottle and the like. Such devices require constant oxygenation and have limited oxygen capacity, are not convenient to use, and cannot guarantee oxygen supply. Therefore, research and development of portable oxygen generators are being pursued at home and abroad. Considering that the Pressure Swing Adsorption (PSA) method is high in oxygen production concentration and does not produce harmful gas, most portable oxygen generators at home and abroad adopt the method. However, such oxygen generators are generally large in size, generally have rugged topography and are inconvenient to carry in a plateau area, and how to reduce the size and weight of oxygen generation equipment on the premise of ensuring the oxygen generation function has become a technical problem which must be overcome when the portable oxygen generator enters the plateau area for use.
Disclosure of Invention
The invention aims to solve the technical problems of improving the structure of the portable oxygen generating equipment, reducing the volume and the weight of the portable oxygen generating equipment and providing the portable oxygen generating equipment which is better suitable for plateau areas.
In order to achieve the purpose, the invention adopts the technical scheme that the invention provides a wearable oxygen generation device, which is characterized in that: including wearable vest and respirator, integrated control system, oxygen system on the vest, control system comprises CPU, atmospheric pressure detection sensor and oxygen saturation detection sensor. The whole oxygen supply system consists of two parts: a molecular sieve type oxygen generation system and an oxygen storage system.
The wearable oxygen generating clothes generate oxygen by adopting a Pressure Swing Adsorption (PSA) method, utilize the adsorption characteristics of zeolite on nitrogen and oxygen with different adsorption amounts, adopt high-pressure adsorption, and separate high-concentration oxygen from air by a cyclic process of low-pressure desorption, and the working principle is as shown in figures 1 and 2: when the small-sized air compressor is in a positive pressure working state, the whole system is in an oxygen generation state, outside air is filtered by a filter, and is compressed into a molecular sieve filled with LiA type zeolite by an air compressor, nitrogen in the air is adsorbed to obtain high-concentration oxygen, an oxygen saturation detection sensor is arranged at an outlet in the molecular sieve, the oxygen saturation in the molecular sieve is monitored in real time, the oxygen is sent into an oxygen bag by an oxygen conveying pipe through a second control valve, an air pressure detection sensor is arranged in the oxygen bag and is responsible for monitoring the oxygen pressure in the tandem type oxygen bag in real time, when the air pressure reaches a preset maximum value, the air compressor stops working, the system stops generating oxygen, and when the air pressure in the central air bag is consumed to a preset minimum value, the system restarts generating oxygen. When the oxygen saturation detection sensor detects that the oxygen concentration is lower than a preset value, the system starts to operate a desorption program, and the air compressor enters a negative pressure working state to carry out negative pressure desorption on the zeolite in the molecular sieve.
FIG. 3 is a working principle diagram of a positive and negative pressure integrated small air compressor used for the wearable oxygen generating clothes. The operating principle of the air compressor is shown in the figure: when the first electromagnetic reversing valve is opened and the second electromagnetic reversing valve is closed (at the original position), the air compressor outputs positive pressure air, when the piston moves rightwards, the working volume in the cylinder is gradually increased, the air pressure in the cylinder is lower than the atmospheric pressure, the air inlet valve is opened, and the outside air enters the cylinder. The inlet valve is closed until the displacement volume becomes maximum. When the piston moves leftwards, the working volume in the cylinder is gradually reduced, the gas in the cylinder is compressed, and the gas pressure is increased. When the pressure in the cylinder is higher than the exhaust pressure, the exhaust valve is opened, and the gas is discharged from the cylinder and enters the molecular sieve. Until the piston moves to the leftmost end position, the exhaust valve is closed. The above process repeats itself when the piston moves to the right again. The piston is continuously reciprocated to continuously feed the compressed air into the molecular sieve.
When the second electromagnetic directional valve is opened and the first electromagnetic directional valve is closed (at the original position), the cylinder outputs negative pressure air. When the piston moves rightwards, the working volume in the cylinder is gradually increased, the air pressure in the cylinder is lower than the atmospheric pressure, the molecular sieve is communicated with the cylinder after the air inlet valve is opened, and the air pressures in the molecular sieve and the cylinder are both lower than the atmospheric pressure until the working volume of the cylinder is maximum, and the air inlet valve is closed. When the piston moves leftwards, the working volume in the cylinder is gradually reduced, the gas in the cylinder, which is lower than the atmospheric pressure, is compressed, and the gas pressure is gradually increased. When the pressure in the cylinder is higher than the exhaust pressure, the exhaust valve opens and the gas is discharged to the atmosphere. Until the piston moves to the leftmost position, the exhaust valve closes. The above process repeats itself when the piston moves to the right again. The piston continuously reciprocates, and the gas in the negative pressure gas storage tank is continuously pumped out and discharged into the atmosphere, so that the pressure of the negative pressure gas storage tank is continuously reduced.
When the air compressor does not work, the first electromagnetic reversing valve and the second electromagnetic reversing valve are closed (in the original position). In the working process of the air compressor, the first electromagnetic directional valve and the second electromagnetic directional valve cannot be opened at the same time, namely, the air compressor cannot be enabled to work in a working state of generating positive and negative pressure air at the same time).
And a power supply is arranged behind the vest and is responsible for supplying power to the whole system, and the vest can be detached and replaced.
Compared with the prior art, the wearable oxygen generation clothes provided by the invention have the following beneficial effects:
1. the wearable oxygen generating equipment is designed, is convenient to wear and does not need to be carried or hung as before;
2. the weight is light and the volume is small;
3. the battery can be replaced, and the battery can be replaced when the battery is not powered, so that the working time is prolonged.
