[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0028] This application provides an improved oxygen concentrator for operation at high altitudes, which is mainly used to solve the problems of existing oxygen production technologies, such as molecular sieve adsorption and membrane separation technologies, which can provide oxygen to a certain extent, but face the problems of reduced efficiency, increased energy consumption and reduced equipment stability in high altitude environments, and provides the following technical solutions, which will be combined with Figures 1-6 Give detailed instructions:

[0029] An improved oxygen concentrator for operation at high altitudes mainly comprises a mounting frame 1, on which are provided a transmission component 2, an air source separation component 3, an air exhaust component 4 and an oxygen exhaust component 5, wherein: the transmission component 2 is an air compressor 21, and the air compressor 21 is provided with an air inlet and an air outlet; the air inlet end of the air source separation component 3 is connected to the air outlet of the air compressor 21, and the air source separation component 3 is used to separate oxygen from impurity gases in the air; the air inlet end of the air exhaust component 4 is connected to the impurity gas exhaust port on the air source separation component 3; the oxygen exhaust component 5 comprises a vent pipe 51 connected to the oxygen exhaust port on the air source separation component 3, a three-way joint 52 is installed on the vent pipe 51, a gas mass flow meter 53 is installed on one of the connection ends of the three-way joint 52, the gas mass flow meter 53 is connected to a sensor mounting seat 55 via a connecting pipe 1 54, and an oxygen concentration sensor is installed on the sensor mounting seat 55 56. An oxygen pressure gauge 58 is connected to the sensor mounting base 55 through a connecting pipe 2 57. When the device is in use, the power is turned on, the transmission component 2 starts working, the ambient air is sucked in and compressed, and the compressed air enters the gas source separation component 3 to separate the oxygen and impurity gases. Unnecessary gases are discharged through the air exhaust component 4, while oxygen passes through the oxygen exhaust component 5. The gas mass flow meter 53, the oxygen concentration sensor 56 and the oxygen pressure gauge 58 monitor the flow, concentration and pressure of oxygen in real time, and feed the data back to the control system. According to the monitoring data, the control system automatically adjusts the operating parameters of the air compressor 21 and adjusts the optimal air intake volume. The device improves the oxygen extraction efficiency through precise gas separation and flow control. The real-time monitoring and feedback adjustment mechanism ensures the stable operation of the system under different environmental conditions. The intelligent control system adjusts the operation of the air compressor 21 according to actual needs, reducing unnecessary energy consumption.

[0030] In this example, see Figure 2 The air compressor 21 is a fully oil-free scroll type. The fully oil-free design avoids the contamination of compressed air by oil and improves the purity of the final oxygen. Since there is no need to deal with oil, the maintenance cost and maintenance workload are reduced. The fully oil-free scroll air compressor 21 can work effectively in high-altitude areas and is not affected by low air pressure.

[0031] Further, see Figure 3The air source separation component 3 is an oxygen production module 31. The oxygen production module 31 is provided with an air inlet pipe 32 connected to the air outlet of the air compressor 21. The oxygen production module 31 is provided with an oxygen exhaust pipe 33 and an impurity gas exhaust pipe 34. The oxygen exhaust pipe 33 is connected to the ventilation pipe 51. Start the air compressor 21 to start compressing air and deliver it to the oxygen production module 31. Monitor the oxygen flow and quality in the oxygen exhaust pipe 33 and the ventilation pipe 51, as well as the gas discharge in the impurity gas exhaust pipe 34. According to the oxygen demand and system feedback, the control system Adjust the operating parameters of the oxygen production module 31 and adjust the air intake volume of the air compressor 21 at the same time. It should be noted that there are two oxygen production modules 31. Two oxygen production modules 31 can provide a larger oxygen output to meet the high demand in high-altitude areas. Using two oxygen production modules 31 can improve the redundancy of the system. Even if one module has a problem, the other can continue to work. The two modules can work alternately, reducing the continuous operation time of a single module, thereby reducing energy consumption. By distributing the workload, the wear of a single module is reduced, and the overall life of the equipment is extended.

[0032] For further information, see Figure 4 The air exhaust component 4 includes a drying cylinder 41, a cooler 42 and a filter 43. The air inlet end of the drying cylinder 41 is connected to the impurity gas exhaust pipe 34 of the oxygen production module 31, the air outlet end of the drying cylinder 41 is connected to the air inlet end of the cooler 42, and the exhaust end of the cooler 42 is connected to the air inlet end of the filter 43. An air outlet pipe 44 is provided on the filter 43. During specific operation, the air compressor 21 and the oxygen production module 31 are started to start the oxygen production process. The impurity gas discharged from the oxygen production module 31 enters the drying cylinder 41 for drying treatment. The drying effect of the drying cylinder 41 is monitored by the control system to ensure that the moisture in the gas is effectively removed. The dried gas enters the cooler 42 for cooling to reduce the gas temperature. The cooled gas is filtered through the filter 43 to remove possible solid particles and impurities. Finally, the treated gas is discharged to the external environment through the air outlet pipe 44. Through drying, cooling and filtering, this component significantly improves the quality of the exhaust gas, reduces potential pollution to the environment, removes moisture and impurities in the gas, and prevents these substances from damaging other components of the oxygen concentrator.

[0033] For details, please refer to Figure 4 A heat dissipation fan 11 corresponding to the air compressor 21 is installed on the mounting frame 1. The heat dissipation fan 11 directly cools the air compressor 21, effectively improving the heat dissipation efficiency. By dissipating heat in time, the air compressor 21 is prevented from being damaged due to overheating, thereby extending the service life of the equipment.

Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
