The temperature and the pressure are two variables influencing the adsorption capacity, and for the same adsorbate, the adsorption quantity of the adsorbent to the adsorbate is in direct proportion to the pressure at the same temperature and under different pressures; and different adsorbates have different adsorption effects on the same adsorbent. By changing the pressure, different adsorbates can be separated. Zeolite is a crystalline aluminosilicate having a microporous cubic lattice, the pores within which determine the adsorption or rejection properties for various substances. Because it can separate molecules with different particle sizes, it is called molecular sieve, so the oxygen generator made by adopting pressure swing adsorption principle is also called molecular sieve oxygen generator.

When the detachable module 1 is mounted on the oxygen generator main body 2, the second oxygen inlet pipe 2014 is inserted into the first oxygen outlet pipe 110 from the first open end of the first oxygen outlet pipe 110, the second closed end 2042 of the second oxygen inlet pipe 204 pushes the blocking block 112 to move in the first oxygen outlet pipe 110, so that the blocking block 112 moves towards the direction close to the first oxygen outlet 113 along the horizontal direction, the spring 111 is stressed and compressed, and is stopped when the blocking block 112 moves to the alignment and communication of the first oxygen outlet 113 and the second oxygen inlet 205, at the moment, the first oxygen outlet pipe is communicated with the second oxygen inlet pipe, so that the detachable module 1 is communicated with the oxygen passage of the oxygen generator main body 2. In this embodiment, when the slide rail 202 reaches the installation position, the slide block 108 is limited by the slide rail, and the installation is completed. The above-mentioned mounting position refers to a position of the detachable module 1 in a final mounting completed state on the oxygen generator main body 2.
In order to improve the efficiency of oxygen separation in the molecular sieve adsorption tower 102, two molecular sieve adsorption towers 102 are provided, and an air inlet pipe, air inlet valves 301 and 305 installed on the air inlet pipe, an air outlet pipe, air outlet valves 303 and 307 installed on the air outlet pipe, a flushing pipe, flushing valves 304 and 308 installed on the flushing pipe, a desorption pipe, and desorption valves 302 and 306 installed thereon are provided for each of the two molecular sieve adsorption towers 102, thereby forming a molecular sieve adsorption tower gas circuit, see fig. 8. Wherein, the air inlet pipeline is a pipeline extending from the outside to the air inlet of the molecular adsorption tower 102; the gas outlet pipeline is a pipeline extending from the gas outlet of the analysis sieve adsorption tower 102 to the outside; the flushing pipeline is a pipeline connected from the gas outlet pipeline and extending to the gas outlet of the molecular sieve adsorption tower 102, and in this embodiment, the interface of the flushing pipeline in the gas outlet pipeline is located at the downstream of the gas outlet valve; the desorption conduit is a conduit extending outwardly from the gas inlet of the molecular sieve adsorption column 102.
In this embodiment, when the molecular sieve adsorption tower 102 is in operation, the air inlet valve 301 (or 305) and the air outlet valve 303 (or 307) are opened, air enters the molecular sieve adsorption tower 102 through the air inlet pipeline, nitrogen, carbon dioxide and the like in the air are adsorbed, and the effluent gas is high-purity oxygen; after the molecular sieve adsorption tower 102 reaches a certain saturation degree, the air inlet valve 301 (or 305) is closed, and the flushing valve 304 (or 308) is opened, so that one part of oxygen generated in the molecular sieve adsorption tower 102 flows out as product gas, the other part of oxygen enters the molecular sieve adsorption tower 102 as back flushing gas through a flushing pipeline, the molecular sieve adsorption tower 102 in a pressure relief stage is subjected to back flushing, and nitrogen, carbon dioxide and the like retained in the molecular sieve are removed; then the flush valve 304 (or 308) is closed and the desorption valve 302 (or 306) is opened to perform decompression desorption on the molecular sieve adsorption tower 102 to release nitrogen, carbon dioxide and the like, thus completing a cycle. Just because the molecular sieve adsorption tower 102 needs to perform adsorption and desorption in the process and can not continuously generate oxygen, the two analytical sieve adsorption towers 102 are adopted to alternately work to ensure continuous oxygen generation, and at the moment, the two molecular sieve adsorption towers 102 work asynchronously. Because only through evacuation desorption regeneration, the molecular sieve adsorption tower 102 is not regenerated and adsorbed thoroughly, thereby the molecular sieve adsorption quantity entering the next cycle is reduced, and the product gas concentration is lower, therefore, a flushing pipeline and a flushing valve are arranged to flush the molecular sieve adsorption tower 102 before the desorption process in one cycle is carried out, and the efficiency of the molecular sieve adsorption tower 102 for separating oxygen is greatly improved.

The flow meter is connected to an oxygen outlet pipeline behind an outlet of the oxygen storage tank, an oxygen outlet control electromagnetic valve is further installed on the oxygen outlet pipeline, the flow meter and the main controller are in communication connection, the flow meter detects the oxygen outlet speed behind the oxygen storage tank and sends the oxygen outlet speed to the main controller, and the main controller controls the oxygen outlet control electromagnetic valve accordingly and adjusts the oxygen outlet speed behind the oxygen storage tank. The main controller is also in communication connection with the display screen so as to send parameters such as oxygen flow, current oxygen concentration, oxygen uptake time and accumulated use time to the display screen and display the parameters on the display screen. The power supply processing circuit is connected with an external power supply and is used for converting the external power supply into power supplies required by all electrical appliances in the oxygen generator and transmitting the power supplies to all the electrical appliances.
The detachable module 1 is further provided with a timer, an air compressor controller, a plurality of solenoid valves and a module controller, wherein the timer, the air compressor controller, and the solenoid valves are all in communication connection with the detachable module controller 104, and the detachable module controller 104 controls the operations of these components. The timer is used for recording the accumulated oxygen inhalation time and the accumulated natural time after the detachable module 1 is started. The electrical equipment in the detachable module 1 is powered by the power supply in the main body 2 of the oxygen generator after the first electrical contact 109 is connected with the second electrical contact 203. Wherein a dedicated lithium battery is allocated to the timer, which is separately powered when the first electrical contact 109 and the second electrical contact 203 are not switched on, and is powered by the oxygen generator main body 2 when switched on, and is charged at the same time.
In addition, in the present embodiment, many improvements are made in reducing intake noise, exhaust noise, and air compressor noise. The air filter 103 contains porous fibrous material inside, and can absorb intake noise; the space between the air filter 104, the air compressor 106 and the molecular sieve adsorption tower 102 is filled with PP (polypropylene) foam, which can absorb intake noise. Regarding exhaust noise reduction, PP foaming materials are adopted around the air outlet of the molecular sieve adsorption tower air passage to absorb exhaust noise.
