[0002] The adsorption oxygen generator draws air into the tank, and then uses pressure to filter the gases other than oxygen through a molecular sieve, so that the oxygen can be separated to prepare pure oxygen. The gas in the molecular sieve is then separated and discharged by reducing the pressure, and the oxygen enters the storage tank through the pipeline.

[0003] Because the screening and waste discharge functions are mainly achieved through changes in pressure, but due to the characteristics of molecular sieves, being in a high-pressure state for a long time will reduce its service life, and the oxygen production tank is a sealed structure, and the pressure will inevitably increase gradually during operation. Secondly, the pressure in the oxygen storage tank of some oxygen generators is insufficient, resulting in the oxygen output is not smooth enough, affecting the use of oxygen.

[0038] The present invention will be further described below in conjunction with the accompanying drawings.

[0039] Please refer to Figure 1 , 3 -4, the present invention provides a boosted output pressure swing adsorption oxygen generator, comprising an oxygen generator 1, wherein two oxygen generators 1 are provided, and a cross-connecting pipe 5 is detachably connected to the side wall between the two oxygen generators 1 near the top, and a ventilation cover plate 502 is detachably connected to the middle of the top side wall of the cross-connecting pipe 5, the ventilation cover plate 502 is an umbrella-shaped structure, and holes are evenly penetrated through the outer wall of the ventilation cover plate 502, an air supply pipe 2 is provided below the oxygen generator 1, and a purification pipe 6 is detachably connected to one end of the air supply pipe 2, and an oxygen storage tank 7 is provided on one side of the oxygen generator 1, and an installation box 701 is detachably connected to the side wall of the oxygen storage tank 7 opposite to the oxygen generator 1 and near the bottom edge, and a gas booster 703 is detachably connected inside the installation box 701;

[0040] The top side walls on both sides of the cross-connecting tube 5 and close to the vertical tube 501 are rotatably connected to a movable sealing plate 506 through a torsion spring, and the bottom side wall of the cross-connecting tube 5 is fixedly connected to a front positioning plate 507, and the front positioning plate 507 is an inclined structure, and one end of the front positioning plate 507 is in contact with one side wall of the movable sealing plate 506, and the top side walls in the cross-connecting tube 5 and close to the movable sealing plate 506 are fixedly connected to a limiting plate 508, and the bottom end of the limiting plate 508 and the side opposite to the movable sealing plate 506 are set as an inclined structure. The interiors of the oxygen production tanks 1 are connected, the vertical pipe 501 is a hollow cylindrical structure, the vertical pipe 501 is the same as the horizontal pipe 5, the ventilation cover plate 502 is connected to the interior of the vertical pipe 501, and a spring 503 is fixedly connected to the side wall of the ventilation cover plate 502 opposite to the vertical pipe 501, and one end of the spring 503 extending into the vertical pipe 501 is fixedly connected to a blocking column 504, and a ring 505 is fixedly connected to the inner wall of the vertical pipe 501 close to the ventilation cover plate 502. The ring 505 is an annular structure and the blocking column 504 is inserted into the ring 505.

[0041] Preferably, when the pressure in the oxygen generator 1 is too high, the movable sealing plate 506 in the cross-connecting pipe 5 will be pushed open, and the pressure will enter the vertical pipe 501 along the cross-connecting pipe 5. After the pressure enters the vertical pipe 501, the blocking column 504 will be pushed upward, thereby pushing the blocking column 504 out of the collar 505, and then the pressure will be discharged from the side wall holes of the ventilation cover 502 to achieve the effect of pressure relief, thereby alleviating the pressure in the oxygen generator 1 and avoiding damage to the molecular sieve 101 due to pressure. As long as the pressure is too high, the movable sealing plate 506 and the blocking column 504 can be opened to achieve the function of automatic pressure adjustment, thereby ensuring the stability of the pressure in the oxygen generator 1, and there is no need to frequently adjust the pressure supply equipment. At the same time, the blocking column 504 is pressed by the spring 503, so that pressure relief will not occur if a certain pressure is not reached, thereby avoiding problems or even failure of oxygen production caused by accidental loss of pressure.

[0042] Please refer to Figure 1 , 4 -6, the output end of the gas booster 703 extends into the oxygen storage tank 7 through the side wall thereof, a baffle 704 is fixedly connected to the bottom side wall of the oxygen storage tank 7 near the installation box 701, a groove 705 is provided in the middle of the side wall of the baffle 704 away from the installation box 701, the groove 705 is an arc-shaped structure, the baffle 704 is an inclined structure, a storage tank is provided on the side of the baffle 704 away from the installation box 701, and the storage tank is a conical structure, an output pipe 702 is fixedly connected to the side wall of the oxygen storage tank 7 away from the installation box 701 and near the bottom, one end of the output pipe 702 is detachably connected to an oxygen outlet baffle 706, and conical holes 707 are evenly provided on the oxygen outlet baffle 706, and the output pipe 702 is communicated with the storage tank.

[0043] Preferably, the prepared oxygen enters the gas booster 703 along the oxygen outlet pipe 4, and the gas booster 703 can pressurize the oxygen entering therein. By pressurizing the oxygen, the stability and smoothness of oxygen delivery are guaranteed. Two conical structures can be formed in the oxygen storage tank 7 through the established baffle 704. Since the oxygen can be pressurized by changing from wide to narrow, the pressure in the oxygen storage tank 7 is guaranteed to be at a certain level. The pressure is discharged outward along the output pipe 702. The oxygen passes through the conical hole 707 opened on the oxygen outlet baffle 706, and the oxygen can be pressurized at the end, thereby ensuring the smoothness and stability of oxygen output.

[0045] Preferably, the air entering the purification pipe 6 passes through the two filter discs 605 in sequence, so that the air can be purified. In this way, it is possible to avoid affecting the oxygen production effect due to excessive impurities in the air. Because filtration will cause impurities to accumulate on the filter disc 605, the toggle column 602 is driven up and down at a regular time to drive the corresponding cleaning plate 606 to clean the side wall of the filter disc 605 to ensure the purity of the filter disc 605 and avoid affecting the subsequent filtering effect on the air. The impurities swept down will fall into the collection box 603 through the bottom of the purification pipe 6. In order to avoid the open collection box 603 affecting the flow of air in the purification pipe 6, the sealing plate 604 can be closed in the top opening of the collection box 603 when not cleaning.

[0046] Please refer to Figure 1-2Two molecular sieves 101 are set up in the oxygen production tank 1, and an oxygen collecting tank 104 is set up between the two molecular sieves 101.

The air supply pipe 2 is fixedly connected to the top side walls opposite to the two oxygen production tanks 1, and a waste pipe 3 is fixedly connected between the two vertical pipes. A discharge pipe is connected to the middle of the top side wall of the waste pipe 3. The waste pipe 3 and the air supply pipe 2 are in a parallel state, and electromagnetic valves are connected to the waste pipe 3, the air supply pipe 2 and the vertical pipe. An oxygen outlet pipe 4 is inserted and connected to the side wall of one side of the bottom of the two oxygen production tanks 1. The two oxygen outlet pipes 4 are oppositely inclined structures. One end of the horizontal pipe at the bottom of the oxygen outlet pipe 4 extends into the installation box 701 and is detachably connected to the air inlet end of the gas booster 703. One end of the oxygen outlet pipe 4 extends into the oxygen production tank 1 and is fixedly connected to the bottom of the oxygen collecting tank 104.

[0047] Preferably, the air supply pipe 2 and the exhaust pipe 3 are established to realize the input of air and the output of exhaust gas. By opening the solenoid valves at different positions, air can be input to different oxygen production tanks 1 and exhaust gas can be discharged, thereby achieving the effect of circulating oxygen production and greatly improving the efficiency of oxygen production. The prepared oxygen can be sent to the oxygen storage tank 7 through the oxygen outlet pipe 4 for pressurized storage.

[0048] Specifically, when the present invention is used, the air purified by the purification pipe 6 is sent into the corresponding oxygen production tank 1 through the air supply pipe 2, and the air is filtered through the molecular sieve 101 by pressurization to separate the oxygen, and then the prepared oxygen is sent to the oxygen storage tank 7 for storage through the oxygen outlet pipe 4, and then the pressure in the oxygen production tank 1 is reduced to discharge the impurities filtered out on the molecular sieve 101 from the waste pipe 3. If the pressure is too high during the preparation process, the pressure can be released through the cross-connecting pipe 5 to ensure the stability of the oxygen produced by the oxygen production tank 1 under variable pressure, and finally the oxygen in the oxygen storage tank 7 can be taken out for use.
