Description

technical field [0001] The invention relates to an oxygen generator, in particular to an aerospace oxygen generator with high oxygen production efficiency, high use comfort and safe use. Background technique [0002] Oxygen therapy and oxygen health care are to use supplementary oxygen to improve the physiological and biochemical internal environment of the human body, and promote a virtuous cycle of metabolic processes, so as to achieve the purpose of treating diseases, relieving symptoms, promoting recovery, preventing disease, and improving health. Clinical practice has proved that oxygen therapy, with its unique therapeutic mechanism, can play an effective therapeutic role in acute and chronic ischemic-hypoxic diseases and secondary diseases caused by hypoxia in various clinical departments. The generation of oxygen concentrator provides convenience for oxygen therapy and oxygen health care. The working principle of the oxygen concentrator is: using molecular sieve phys...

Problems solved by technology

[0003] Oxygen generators mostly use molecular sieves to separate nitrogen and oxygen. Due to the large requirements for the gas inlet and outlet, the gas inlet and outlet time is short, the volume of the gas inlet and outlet equipment and compressor equipment is limited, and the airflow velocity and density are high during the inlet and outlet. Produces a lot of noise, and cannot provide a quiet and comfortable environment for users during oxygen therapy or oxygen care

Traditionally, the sound-absorbing cotton is used to reduce the noise of the oxygen generator. The disadvantage of this method is that the internal paste of the sound-absorbing cotton increases the overall volume of the oxygen generator and increases the production cost, and the sound-absorbing cotton also has the function of heat insulation, which is not conducive to the oxygen generator. The heat dissipation of internal components affects the performance and life

[0004] For different oxygen therapy requirements, the humidity requirements for oxygen are also different. Most of the existing oxygen generators are equipped with humidified water cups, and the oxygen is passed into the humidified water cups and supplied for use after being humidified by water, such as the patent No. 201220022919.7. An oxygen concentrator can be embedded in a detachable and washable humidification water cup. The water cup is divided into an air inlet chamber, an air outlet chamber and a bubble chamber. Oxygen after humidification is supplied by the air outlet cavity. The disadvantages are: the structure of the water cup is complicated, the production is difficult, the cost is high, and it is inconvenient to disassemble and clean; the oxygen is discharged into the water through the bubble hole, the size of the bubble hole is limited, and the bubble hole directly Affecting the oxygen supply speed, there is a problem of too low oxygen supply; the bubbling of oxygen in the bubble chamber is easy to generate noise, which affects the comfort of the oxygen concentrator; in addition, when the structure in the water cup is damaged or blocked, the pressure in the cup is too high , unable to effectively release pressure, there are potential safety hazards, and the service life is short

The nitrogen discharge of the existing oxygen generator is directly discharged from the exhaust mechanism of the bottom plate. Since the bottom plate is facing downward when the oxygen generator is placed, the airflow is easy to flow back into the oxygen generator during rapid exhaust, the exhaust efficiency is low, and it will produce Larger wind noise; in addition, the compressor generates heat after long-term operation, and cannot effectively dissipate heat in the limited space of the oxygen generator, which affects the service life of the compressor and other electrical components in the oxygen generator
