The working principle of the invention is as follows: before the oxygen generator is used, firstly, the cooling pipe 204 in the freezing chamber 201 is communicated with an external cold source, each group of electric equipment in the oxygen generator is communicated with an external power source, so that the equipment can normally operate, then the compressor 102 is started, the compressor 102 sucks the external air through the filter 101, the filter 101 filters dust and impurities in the air, the compressor 102 compresses the air into high-pressure high-heat gas, the high-pressure high-heat gas is sent into the heat exchange pipe 202 in the heat exchange chamber 2, the compressed air rapidly disperses the heat into the heat exchange chamber 2 through the heat dissipation fin 203 and enters the freezing chamber 201 along the heat exchange pipe 202, the temperature of the compressed air is reduced under the condition that the cooling pipe 204 is cooled, the moisture in the air is liquefied at low temperature and separated from the air, and is collected and discharged through the water discharge pipe 206, the residual dry low-temperature compressed air returns to the heat exchange chamber 2 through the air return pipe 205 and is distributed outside the heat exchange pipe 202, so that the low-temperature compressed air absorbs the heat emitted before, the temperature of the compressed air is increased, the energy loss required by subsequent heating of the air is reduced, the use efficiency is improved, then the compressed air enters the sealing mechanism 3 through a pipeline, the compressor 102 continuously sends the outside air into the sealing mechanism 3, the pressure of the sealing mechanism 3 is continuously increased, so that the nitrogen, carbon dioxide and other gases in the air are adsorbed by the multiple groups of molecular sieves 14 in the adsorption mechanism 8, and when the oxygen reaches a proper concentration, a valve between the sealing mechanism 3 and the storage tank 7 is opened, so that the oxygen can enter the storage tank 7;
when nitrogen needs to be removed from the adsorption mechanism 8, firstly, the air suction pump 702 is started, the air suction pump 702 pumps oxygen in the storage tank 7 into the recoil mechanism 6, the air pressure in the recoil mechanism 6 is continuously increased until the air pressure in the recoil mechanism 6 is greater than the external normal pressure and the torque of the torsion spring bar 1105 and is less than the pressure in the sealing mechanism 3 until the pressure is greater than the elastic force of the return spring 602, the push plate 601 moves under the action of the air pressure, so that two ends of the connecting wire 603 are respectively communicated with the lead 15 and the external power cord, the lead 15 is communicated with a plurality of groups of electric heating tubes 403, the electric heating tubes 403 heat the limit roller 402 and the molecular sieve 14 needing to be backwashed, then, a plurality of groups of electric push rods 1106 are started, the electric push rods 1106 push the second sealing frame 11 to move and are clamped with the sealing slots 804 arranged on the end face of the adsorption mechanism 8, so as to seal one end of the molecular sieve 14 between two groups of partition plates 805 in the adsorption mechanism 8, and the push rod 10 will be squeezed in the process of the second sealing frame 11 moving, the push rod 10 drives the first sealing frame 9 to move, so that the first sealing frame 9 is inserted into the exhaust pipe 5, and is clamped with the inner wall of the sealing mechanism 3 through the sealing edge 901, the joint between the exhaust pipe 5 and the first sealing frame 9 is sealed, so that an exhaust space is formed between the first sealing frame 9, the second sealing frame 11 and the two groups of partition boards 805 and is separated from the sealing mechanism 3, at this time, the exhaust valve 501 is opened, so that the exhaust space is in contact with the outside air, and the pressure in the exhaust space is far greater than the outside air pressure, so that the gas in the exhaust space is exhausted through the exhaust pipe 5, the adsorbed nitrogen in the molecular sieve 14 is also exhausted through the exhaust pipe 5 along with the air flow, and the heated molecular sieve 14 is more easily separated from the nitrogen, until the air pressure in the exhaust space is gradually leveled with the external normal pressure, the air pressure in the backflushing mechanism 6 is larger than the external normal pressure and the torsional force of the torsion spring bar 1105, so that the oxygen in the backflushing mechanism 6 can push the rotating plate 1101 to open, and the oxygen is flushed into the exhaust space, thereby carrying out oxygen backflushing on the multiple groups of molecular sieves 14, and improving the cleaning degree of the molecular sieves 14;
after cleaning, the exhaust valve 501 is closed, the power of the getter pump 702 is increased, oxygen is continuously sent into the exhaust space, the air pressure in the exhaust space after nitrogen removal is continuously increased until the air pressure in the exhaust space is kept the same as the air pressure in the sealing mechanism 3, at this time, the getter pump 702 is stopped to operate, the torsion spring bar 1105 drives the rotating plate 1101 to return, the electric push rod 1106 is started, the electric push rod 1106 drives the second sealing frame 11 to return, the return spring 902 pulls the first sealing frame 9 and the push rod 10 to return, the limit fixation on the adsorption mechanism 8 is released, the getter pump 702 is started reversely, the high-pressure oxygen in the recoil mechanism 6 is pumped back into the storage tank 7 by the getter pump 702, the push plate 601 returns under the action of the return spring 602, the connection of the lead 15 and an external power supply is cut off, and the electric heating pipe 403 is not in operation;
when other multiunit molecular sieve 14 need be clear away, starter motor 401, motor 401's output drives adsorption apparatus 8 through two sets of gears and gear ring 803 block and rotates, and adsorption apparatus 8 rotates through bearing shaft 12, makes other molecular sieve 14 remove between blast pipe 5 and the breathing pipe, conveniently carries out the step-by-step clearance to multiunit molecular sieve 14, can handle molecular sieve 14 under the state that need not shut down, has improved the availability factor.
