[0047] Example

[0048] To address the issue that existing oxygen compression equipment cannot produce pure, humid oxygen, reference... Figures 1-3 As shown, this application discloses an oxygen generation device based on an air compressor, which is provided with compressed air by an oil-free reciprocating air compressor 10, including an oil-free reciprocating air compressor 10 and an oxygen generation mechanism 20 disposed on the air storage tank of the oil-free reciprocating air compressor 10.

[0049] The oxygen production mechanism 20 includes an aluminum six-way valve 21 at the inlet end, an aluminum six-way valve 22 at the outlet end, a high-pressure gas storage tank 23, an oxygen-generating molecular sieve 24, an oxygen storage tank 25, and an oxygen humidifier 26.

[0050] The aluminum six-way valve 21 at the air inlet end is connected to the high-pressure gas storage tank 23 through the first pipeline 50. The aluminum six-way valve 21 at the air inlet end is equipped with a first solenoid valve 211 and a second solenoid valve 212. The first solenoid valve 211 is provided with a second pipeline 60 for connecting to the oil-free piston air compressor 10. The solenoid valve is equipped with a nitrogen exhaust connector.

[0051] The high-pressure gas storage tank 23 is connected to the oxygen-generating molecular sieve 24 via a third pipeline 70;

[0052] The oxygen-generating molecular sieve 24 is connected to the oxygen storage tank 25 through the fourth pipeline 80, and a one-way valve 241 is installed at the connection between the fourth pipeline 80 and the oxygen-generating molecular sieve 24 to prevent oxygen in the oxygen storage tank 25 from flowing back to the oxygen-generating molecular sieve 24.

[0053] The oxygen storage tank 25 is connected to the exhaust end aluminum six-way valve 22 via the fifth pipeline 90;

[0054] The oxygen humidifier 26 is installed below the aluminum six-way valve 22 at the exhaust end, near the oxygen outlet;

[0055] During oxygen preparation, the first solenoid valve 211 opens the storage tank of the oil-free piston air compressor 10 and supplies compressed air to the inlet aluminum six-way valve 21 through the two pipes. The compressed air in the inlet aluminum six-way valve 21 enters the high-pressure gas storage tank 23 and then enters the oxygen-generating molecular sieve 24. The gas undergoes a pressure swing adsorption (PSA) process in the oxygen-generating molecular sieve 24, where nitrogen is adsorbed and oxygen passes through and enters the oxygen storage tank for storage. When the oxygen is used, the oxygen stored in the oxygen storage tank 25 enters the exhaust aluminum six-way valve 22. During this process, the oxygen humidifier 26 humidifies the oxygen and then discharges it from the oxygen outlet.

[0056] When oxygen production stops, the first solenoid valve 211 closes and the second solenoid valve 212 opens. During this process, the gas inside the high-pressure gas storage tank 23 and the nitrogen gas left after separation (the nitrogen gas adsorbed by the oxygen-generating molecular sieve 24 flows back to the high-pressure gas storage tank 23) will be discharged through the second solenoid valve 212.

[0057] To ensure the purity and dryness of the oil-free reciprocating air compressor 10, this application installs an air filter 30 at the outlet end of the compressor head of the oil-free reciprocating air compressor 10. The air filter 30 is connected to a dryer 40 through a sixth pipeline 100. The dryer 40 is connected to the air tank of the oil-free reciprocating air compressor 10 through a seventh pipeline 110. When the oil-free reciprocating air compressor 10 is working, the compressed gas discharged from its compressor head will first be filtered by the air filter 30 and then dried by the dryer 40 before entering the air compressor's air tank for storage.

[0058] In addition to the above structure, this application also includes a controller 27, which is connected to the exhaust end aluminum six-way valve 22 through an eighth pipeline 120. The controller 27 is used to detect the amount of oxygen in the oxygen storage tank 25 in real time. If the controller 27 detects that the internal pressure of the oxygen storage tank 25 has not reached the set value of the controller 27, then the first solenoid valve 211 needs to be opened to allow the entire device to enter the oxygen generation stage. Conversely, if the controller 27 detects that the internal pressure of the oxygen storage tank 25 has reached the set value of the controller 27, then the second solenoid valve 212 needs to be opened to allow the nitrogen gas generated by separation to be discharged.

[0059] In order to manually detect the pressure value inside the oxygen storage tank 25 in real time, this application also installs a pressure gauge 221 on the aluminum six-way valve 22 at the exhaust end. In specific implementation, the operator can accurately know the pressure value inside the oxygen storage tank 25 based on the value displayed by the pressure gauge 221.

[0060] In order to facilitate the output of oxygen from the exhaust end aluminum six-way valve 22 of this application, an oxygen outlet connector 222 is installed on the oxygen outlet of the exhaust end aluminum six-way valve 22. In specific implementation, the corresponding equipment can be connected to the oxygen outlet connector 222 by setting up pipelines, which is convenient and quick to use.

[0061] In one specific embodiment, the oxygen humidifier 26 of this application includes a pure water bottle 261, a water-absorbing cotton swab 262, and a water atomizing head 263. The water atomizing head 263 is installed at the mouth of the pure water bottle 261 and connected to the exhaust end aluminum six-way connector 22. The water-absorbing cotton swab 262 is installed vertically inside the pure water bottle 261 and extends to the bottom of the water atomizing head 263. During the process of oxygen storage tank 25 delivering oxygen to the outside, the water-absorbing cotton swab 262 continuously absorbs the liquid in the pure water bottle and sprays it into the exhaust end aluminum six-way connector 22 through the water atomizing head 263. In this way, the oxygen can be mixed with the atomized water vapor and discharged together through the oxygen outlet connector 222.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
