Description

Technical Field

[0001] The utility model relates to the technical field of oxygen production equipment, in particular to a portable oxygen production device. Background Art

[0002] Oxygen is a colorless and odorless gas. It is an important substance for the survival of the human body, and it is also an important substance for the survival of other animals and plants. Without oxygen, the natural world will be lifeless. Its importance is like water. It is widely used. All walks of life cannot do without oxygen. There are many kinds of oxygen concentrators on the market. Due to the different principles of oxygen production, oxygen concentrators are mostly divided into molecular sieve principle oxygen concentrators, polymer oxygen-enriched membrane principle oxygen concentrators, electrolytic water principle oxygen concentrators and chemical reaction principle oxygen concentrators. Molecular sieve oxygen concentrators are the only mature ones at present. The existing molecular sieve principle oxygen concentrators are mostly composed of compressors and molecular sieves. They use air separation technology and molecular sieves. Adsorption performance, through physical principles, with the compressor as the power, the nitrogen and oxygen in the air are separated, and finally a high concentration of oxygen is obtained. The compressor draws in and pressurizes the air through the filter head, and then pumps it into the molecular sieve. The zeolite inside the molecular sieve adsorbs the nitrogen in the air, and the remaining oxygen is pumped into the gas cylinder, and then the oxygen supply is completed through the connector and nasal oxygen tube. In the plateau environment, in order to resist altitude sickness, people often carry oxygen concentrators with them. Traditional oxygen concentrators are mostly carried on the back with an external strap, which is easy to entangle and lose, making it inconvenient to carry the oxygen concentrator. For this reason, we propose a portable oxygen concentrator. Utility Model Content

It is convenient to carry with you and the length of the shoulder strap can be adjusted at will, which is very convenient.

[0024] The working principle of the portable oxygen concentrator provided by the present invention is as follows: when carrying the oxygen concentrator, the oxygen concentrator can be quickly taken out through the handle 37. When the oxygen concentrator needs to be carried on the back, the shoulder strap 34 is pulled outward. As the shoulder strap 34 slowly moves outward, the annular sleeve is continuously reversed, the volute spring 32 is continuously contracted under the force, and the shoulder strap 34 moves outward along with the guide column 33. When the shoulder strap 34 is pulled out to a suitable length, the shoulder strap 34 needs to be fixed, and the knob 363 is turned forward, and the shaft 361 and the cam 362 also rotate accordingly. , until the raised part of the cam 362 contacts the side of the movable piece 352 close to the center of the mounting block 2, the outer edge of the cam 362 squeezes the movable piece 352, causing the two movable pieces 352 to move outward synchronously, and the spring 353 is compressed. As the movable piece 352 moves outward, the locking head contacts the surface of the strap 34, squeezing the strap 34 between the two limiting posts 354. At this time, the strap 34 is squeezed between the locking head and the two limiting posts 354, and the huge friction force fixes the strap 34. At this time, the strap can be quickly carried. When the oxygen concentrator is carried and needs to be stored, it is only necessary to reverse the knob 363 to drive the rotating shaft 361 and the cam 362 to rotate. The raised part of the cam 362 leaves the side of the movable piece 352 close to the center of the mounting block 2, and the movable piece 352 returns to its original position. The spring 353 is not forced to expand, and the locking head also leaves the surface of the strap 34. At this time, the strap 34 is not forced, and the spiral spring 32 rebounds, driving the annular sleeve to rotate forward. The strap 34 is retracted and rewound on the surface of the annular sleeve to complete the storage work. When the oxygen concentrator is used to supply oxygen, The single chip computer 10 controls the operation of the micro compressor 5, which inhales external air from the filter head 4. The filter head 4 can filter pollutants in the air. The inhaled air is pressurized by the micro compressor 5, and then passes through the molecular sieve 6 and is pumped into the gas storage bottle 7. During this period, when passing through the molecular sieve 6, the zeolite inside the molecular sieve 6 adsorbs the nitrogen in the air, and the remaining oxygen is pumped into the gas storage bottle 7. When oxygen supply is needed, it is only necessary to connect the external nasal oxygen tube to the connector 8 to start oxygen supply.

[0025] It is worth noting that the single chip microcomputer 10 disclosed in the above embodiment is an S7-200 single chip microcomputer, the micro compressor 5 is a 6397B-1p30s-24 micro compressor, and the single chip microcomputer 10 controls the operation of the micro compressor 5 using a method commonly used in the prior art.
