Embodiment 1
[0023] Embodiment 1: the normal temperature oxygen pressurization device in this scheme, such as figure 1 and figure 2 As shown, it includes a pneumatic supercharger 2 , an oxygen generator 7 and an air compressor 1 for providing compressed air to the oxygen generator 7 . Pneumatic supercharger 2 is the prior art, also known as pneumatic booster pump, pneumatic supercharger 2 has a driving gas input end for passing into driving gas, a gas to be compressed input and an output for passing into gas to be compressed At the output end of the compressed gas, the oxygen generator 7 is a pressure swing adsorption oxygen generator. The output end of the air compressor 1 communicates with the air source input end of the oxygen generator 7 to provide the oxygen generator 7 with the compressed air required for oxygen production. The output end of the oxygen generator 7 communicates with the input end of the gas to be compressed of the pneumatic supercharger 2 to provide the pneumatic s...
Embodiment 2
[0034] Embodiment 2: The improvement of this embodiment on the basis of Embodiment 1 is: remove the filling head 4 on the output end of the pneumatic booster 2, and the gas output end of the pneumatic booster 2 is connected with a pressure gas cylinder 6 , The pressure gas cylinder 6 is processed with an exhaust port, and a pressure reducing valve and a shut-off valve are installed on the exhaust port. The exhaust port is connected with a filling head 4 through a pipeline. The compressed gas with higher pressure produced by the pneumatic supercharger 2 enters the pressure gas storage bottle 6 for storage, and is filled into the oxygen portable bottle 5 after decompression when necessary. On the one hand, the pressure gas storage bottle 6 can store a large amount of compressed oxygen, and when necessary, oxygen is released from the pressure gas storage bottle 6 for filling, so as to avoid repeatedly starting the compressor or the pneumatic supercharger 2 according to the fillin...
Embodiment 3
[0035] Embodiment 3: In this embodiment, on the basis of Embodiment 1, the pressure gas cylinder 6 is a medical pressure cylinder. The medical pressure bottle has a high pressure safety factor, which further plays a role in safety protection.
