DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1The utility model provides a technical solution: a portable oxygen concentrator movement, comprising: a main support 1, an oxygen concentrator shell is arranged on the outside of the main support 1; a molecular sieve cartridge 2, symmetrically plugged and arranged on the left and right sides of the main support 1, an upper end cap 4 and a lower end cap 3 are respectively installed and arranged on the upper and lower ends of the molecular sieve cartridge 2, the lower end cap 3 and the upper end cap 4 are both connected to each other and provided with an end cap nozzle 5, the end cap nozzle 5 is connected to the inner cavity of the molecular sieve cartridge 2; a cover plate 7, detachably arranged on the lower end surface of the main support 1, the cover plate 7 is in conflict with the lower end surface of the lower end cap 3; a base plate 8, detachably arranged in the middle of the lower end surface of the main support 1, a compressor 10 is arranged on the base plate 8, and a compressor 10 is arranged in the middle of the main support 1 0 matched with the middle groove 16; the top plate 11 is arranged on the upper part of the middle groove 16 and the oxygen valve 12 is arranged symmetrically on the center thereof, and the corners of the middle groove 16 are provided with gas channels 17, and the gas channels 17 are respectively connected with the oxygen valve 12 and the end cover nozzle 5 on the lower end cover 3; the gas storage tank 13 is arranged above the compressor 10 and is detachably connected with the main bracket 1; the flushing valve 14 and the breathing valve, both of which are connected and arranged on the gas storage tank 13, the flushing valve 14 is symmetrically arranged on the upper end face of the gas storage tank 13, the breathing valve is arranged on the front end face of the gas storage pipe, and the end cover sealing nozzle on the upper end cover 4 is connected with the flushing valve 14 through the adapter 9 matching pipeline, and the adapter 9 is fixedly connected to the main bracket 1.

[0022] The utility model can effectively reduce the pipeline transmission cost and the sealing cost between the valve body and the pipeline by integrating the flushing valve 14 and the breathing valve on the gas storage tank 13; at the same time, by providing the cover plate 7, the adapter 9 and the air outlet channel, the personnel can directly pull out the molecular sieve cartridge 2 after removing the cover plate 7, so that the replacement and removal of the molecular sieve cartridge 2 can be completed without removing the oxygen generator housing. When installing the molecular sieve cartridge 2 again, it is only necessary to push the molecular sieve cartridge 2 into the inner cavity of the main bracket 1 again, and then fix the cover plate 7 again, and the sealing performance between the molecular sieve cartridge 2 and the air outlet channel and the adapter 9 is ensured by the end cover nozzle sealing ring 6 arranged on the end cover nozzle 5.

[0023] The principle of oxygen production of the whole device: the compressor 10 first injects the compressed gas into the lower end of the molecular sieve cylinder 2 through the oxygen production valve 12. After the molecular sieve adsorbs the nitrogen in the compressed gas, the high-concentration oxygen enters the flushing valve 14 from the upper end of the molecular sieve through the conversion head, and the flushing valve 14 (there is also a one-way valve between the flushing valve 14 and the gas tank 13, so the oxygen in the gas tank 13 will not flow back to the flushing valve 14) is injected into the gas tank 13. Through the set oxygen concentration sensor 15, the sensor senses the change in pipeline pressure caused by breathing, and the breathing valve receives the signal of the sensor to achieve short-term opening and closing, and the high-concentration oxygen in the oxygen tank will be released intermittently. Due to the limited space in a single molecular sieve cylinder 2, it is necessary to discharge nitrogen regularly. At this time, through the arrangement of two molecular sieve cylinders 2 and the matching oxygen production valve 12 and flushing valve 14 and other related components, it is possible to achieve that the two molecular sieve cylinders 2 can work independently of each other, and then carry out nitrogen discharge and oxygen production processes respectively. By controlling the switching of the oxygen production valve 12, the oxygen production and nitrogen exhaust between the two molecular sieve cylinders 2 are switched. When the oxygen production valve 12 is switched, the pressure in the molecular sieve cylinder 2 drops sharply, and the high-concentration nitrogen is adsorbed by the molecular sieve and analyzed from the lower end of the molecular sieve to the oxygen production valve 12 and discharged into the compressor 10 box through the nitrogen exhaust muffler.

[0024] In this embodiment, the end cover nozzle 5 on the lower end cover 3 is plugged into the lower end of the gas channel 17, and an end cover nozzle sealing ring 6 is arranged between the end cover nozzle 5, the gas channel 17 and the adapter 9. Figure 5 As shown, the end cover nozzle sealing ring 6 can effectively ensure the sealing performance between the molecular sieve cartridge 2 and the gas channel 17 and the adapter 9 after installation.

[0025] In this embodiment, the lower part of the breathing valve is connected to an oxygen concentration sensor 15, and the breathing valve and the oxygen-generating valve 12 are electric valves. Figure 1 As shown, through the oxygen concentration sensor 15, the sensor senses the change in pipeline pressure caused by breathing, and the breathing valve receives the signal from the sensor to achieve short-term opening and closing, and the high-concentration oxygen in the oxygen storage tank will be released intermittently.

[0026] In this embodiment, a one-way valve is arranged between the flushing valve 14 and the gas storage tank 13 to ensure that the oxygen in the gas storage tank 13 does not flow back to the flushing valve 14 .
