[0002] Oxygen production technology is divided into molecular sieve oxygen production principle, electronic oxygen production principle, chemical oxygen production principle, etc. Among them, the molecular sieve oxygen production principle is based on the difference in the adsorption capacity of zeolite molecular sieves for oxygen and nitrogen in the air to achieve the separation of oxygen and nitrogen, and can directly extract high-purity oxygen from the air.

[0003] When using oxygen supply equipment to produce oxygen, it is necessary to use an air compressor to compress the air and separate the oxygen in the air through a molecular sieve. During the air compression process, the compressed air will absorb a large amount of moisture in the air, affecting the purity of the compressed air, making it difficult to separate the oxygen when the compressed air passes through the molecular sieve, thereby reducing the efficiency of the oxygen supply equipment. For this reason, a high-efficiency oxygen production equipment is proposed. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0023] like Figures 1 to 5 As shown, the utility model provides a high-efficiency oxygen supply device, including a housing 1, and also including:

[0024] Oxygen production equipment, which is arranged inside the housing 1 and is used to produce oxygen;

[0025] An air drying structure, which is arranged on the oxygen production equipment and is used to remove moisture from the air;

[0026] The oxygen production equipment includes two groups of zeolite cylinders 2, which are arranged inside the housing 1. The zeolite cylinders 2 control air intake through a control circuit 8. The air outlet of the zeolite cylinder 2 is connected to an exhaust pipe 3, and a pressure regulator 5 is arranged in the middle of the exhaust pipe 3. The air inlet of the zeolite cylinder 2 is provided with a ventilation pipe 4, and the bottom end of the ventilation pipe 4 is connected to an air compressor 6, and the air inlet of the air compressor 6 is connected to a filter 7;

[0027] Among them, the air drying structure includes a cooler 9, which is sleeved on the ventilation pipe 4. A mounting shell 10 is provided in the middle of the ventilation pipe 4. An arc plate 11 is installed inside the mounting shell 10. A rotating part 12 is sleeved inside the mounting shell 10. Four groups of absorbent cotton 13 are inlaid on the outer side of the rotating part 12. A fixed frame 14 is installed on one side of the mounting shell 10. A movable rod 15 is sleeved inside the fixed frame 14. A reset spring 17 is sleeved on the outer surface of the movable rod 15. A pressure plate 16 is installed on the end of the movable rod 15. A first motor 18 is installed on one side of the fixed frame 14. A cam 19 is installed on the output shaft of the first motor 18. A drainage part 20 is connected to one side of the mounting shell 10. A second motor 21 is installed on the front of the mounting shell 10.

[0028] The cooler 9 can quickly cool the air entering the ventilation pipe 4, so that the water vapor in the air can be condensed into water droplets. When the water droplets pass through the absorbent cotton 13, they will be absorbed by the absorbent cotton 13. After one group of absorbent cotton 13 absorbs moisture, the operation of the second motor 21 can drive the absorbent cotton 13 to rotate through the rotating part 12, and switch to another group of dried absorbent cotton 13. At this time, the operation of the first motor 18 will cause the cam 19 to rotate, and then the cooperation between the cam 19 and the pressure plate 16 can drive the pressure plate 16 to squeeze the absorbent cotton 13, and squeeze the moisture out of the drainage part 20, so as to continuously remove moisture from the air and improve the efficiency of oxygen production.

[0029] The middle portion of the ventilation pipe 4 is spirally shaped and is wound around the outer surface of the cooler 9 .

[0030] The spiral design of the vent pipe 4 can increase the contact area between the vent pipe 4 and the cooler 9 . Meanwhile, the vent pipe 4 is cooled by the cooler 9 , so that the moisture in the compressed air inside the vent pipe 4 can be condensed.

[0031] The return spring 17 is elastically supported between the movable rod 15 and the fixing frame 14 , and the output shaft of the second motor 21 is connected to the rotating member 12 .

[0032] Through the design of the reset spring 17, the movable rod 15 has good elastic reset performance. At this time, since the reset spring 17 is in a compressed state, it will apply an elastic force to the movable rod 15, so that when the cam 19 releases the pressure on the pressure plate 16, the pressure plate 16 will be reset through the movable rod 15.

[0033] The cam 19 is in press contact with the pressing plate 16 , and the pressing plate 16 is in press contact with the absorbent cotton 13 .

[0034] Through the cooperation between the cam 19 and the pressing plate 16 , when the cam 19 presses the pressing plate 16 , the pressing plate 16 will press the absorbent cotton 13 , so that the moisture inside the absorbent cotton 13 can be squeezed out from the drainage member 20 .

[0035] The middle part of the rotating member 12 is hollowed out, and the arc plate 11 is sleeved with the rotating member 12 .

[0036] Through the design of the arc plate 11, the two sides of the rotating member 12 can be closed so that the two adjacent groups of absorbent cotton 13 are not connected to each other, so that the absorbent cotton 13 can be driven to rotate by the rotating member 12 to switch the wet absorbent cotton 13.

[0037] The working principle and use process of this utility model:

[0038] First, air is extracted through the air compressor 6, and impurities in the air are filtered through the filter 7. The air entering the ventilation pipe 4 can be quickly cooled through the cooler 9, so that the water vapor in the air can be condensed into water droplets. When the water droplets pass through the absorbent cotton 13, they will be absorbed by the absorbent cotton 13. After one group of absorbent cotton 13 absorbs moisture, the operation of the second motor 21 can drive the absorbent cotton 13 to rotate through the rotating part 12, and switch to another group of dried absorbent cotton 13. At this time, the operation of the first motor 18 will cause the cam 19 to rotate. Furthermore, the cam 19 and the pressure plate 16 can cooperate to drive the pressure plate 16 to squeeze the absorbent cotton 13 and squeeze the water out of the drainage piece 20, so as to continuously remove the moisture in the air. At this time, the air will enter the interior of the zeolite cylinder 2, and the zeolite inside the zeolite cylinder 2 will form a molecular sieve. Since oxygen molecules are smaller than nitrogen molecules, they can filter oxygen molecules. After one group of zeolite cylinders 2 is blocked, the control circuit 8 can be used to control the opening of another group of zeolite cylinders 2, and the blocked zeolite cylinders 2 can be unblocked, so that it can continuously supply oxygen, thereby improving the efficiency of oxygen supply.
