Description

Technical Field

[0001] The utility model relates to the field of oxygen generators, and particularly to an integrated structure of a separation tower tube and an oxygen storage tank for an oxygen generator. Background Art

[0002] Oxygen generators are widely used in households, hospitals, sanatoriums, schools, hotels, sports venues, bars, oxygen bars, and high-altitude military stations, etc. With the enhancement of people's health awareness, the market for household oxygen generators has gradually emerged and become an important device for health care. As a household medical device, its market demand is continuously increasing with people's pursuit of a healthy life.

[0003] The separation tower is the core component in an oxygen generator to achieve air separation. It is internally filled with molecular sieves, and the separation is achieved by utilizing the difference in the adsorption capacities of the molecular sieves for nitrogen and oxygen. Under pressure, nitrogen is adsorbed by the molecular sieves, while oxygen passes through the molecular sieves and is separated; the oxygen storage tank in the oxygen generator is used to store the oxygen separated in the separation tower and supply it to the user.

[0004] In the existing market, the separation tower and the oxygen storage tank of an oxygen generator are both independent components, and structurally they are independent plastic and aluminum parts in the oxygen generation system, occupying a relatively large space and unable to effectively utilize the internal space of the oxygen generator. Moreover, the oxygen separated in the separation tower is connected to the oxygen storage tank through a pipe at the oxygen outlet, with numerous and complex pipelines, and the sound insulation effect of the pipeline materials is generally poor.

[0005] Structural disadvantages of the existing separation tower and oxygen storage tank of an oxygen generator:

[0006] 1) There are many connecting pipelines, resulting in an increase in potential hazards, as well as an increase in material costs, processing costs, and assembly labor costs;

[0007] 2) With many pipelines, the tidiness is relatively poor;

[0008] 3) Most of the pipeline materials are silica gel, and the sound insulation effect is poor. Summary of the Utility Model

[0009] The purpose of the utility model is to overcome the above deficiencies of the existing technology and provide an integrated structure of a separation tower tube and an oxygen storage tank for an oxygen generator.

[0010] According to one aspect of the utility model, there is provided an integrated structure of a separation tower tube and an oxygen storage tank for an oxygen generator, comprising:

[0011] A first separation tower tube for loading molecular sieves;

[0012] A second separation tower tube for loading molecular sieves, the second separation tower tube being arranged in parallel with the first separation tower tube; and

[0013] The oxygen storage tank is arranged between the first separation tower pipe and the second separation tower pipe, and the first separation tower pipe, the second separation tower pipe and the oxygen storage tank are integrally formed.

[0014] The integral structure of the separation tower pipe and the oxygen storage tank of the present utility model makes use of the extra space size between the first separation tower pipe and the second separation tower pipe to form an oxygen storage tank. Since the first separation tower pipe, the second separation tower pipe and the oxygen storage tank are integrally formed, the original three components of the two separation tower pipes and the oxygen storage tank can be combined into one component, and the assembly is simple. Molecular sieves are respectively installed inside the first separation tower pipe and the second separation tower pipe. After installing the appropriate sealing end caps at the ends of the first separation tower pipe, the second separation tower pipe and the oxygen storage tank, the compressed gas generated by the compressor of the oxygen generator can enter the first separation tower pipe and the second separation tower pipe through the air inlet on the sealing end cap. The oxygen separated from the first separation tower pipe and the second separation tower pipe can enter the oxygen storage tank through the air duct on the sealing end cap for storage, and the oxygen stored in the oxygen storage tank can be discharged from the oxygen outlet on the sealing end cap; the integral structure of the separation tower pipe and the oxygen storage tank of the present utility model has a simple structure, can reduce pipeline connection, reduce material cost, and effectively utilize the space inside the oxygen generator. In addition, since the first separation tower pipe, the second separation tower pipe and the oxygen storage tank are integrally formed, the assembly can be reduced, the assembly can be simplified, the defective products caused by the pipelines, joints and the components themselves can be reduced, the yield rate can be improved, and moreover, while reducing the materials, the overall machine noise can be effectively reduced.

[0015] Furthermore, the cross-sections of the first separation tower pipe and the second separation tower pipe are both circular, and the cross-section of the oxygen storage tank is quadrilateral.

[0016] Therefore, the oxygen storage tank with a quadrilateral cross-section can effectively utilize the space size between the first separation tower pipe and the second separation tower pipe, and ensure the maximum volume of the oxygen storage tank under the condition that the sizes of the first separation tower pipe and the second separation tower pipe are certain.

[0017] Furthermore, a first rib is arranged on the outer wall of the first separation tower pipe along its length direction, and first threaded holes for fixing with the external sealing end cap are respectively arranged at both ends of the first rib.

[0018] Therefore, when installing the appropriate sealing end caps (upper sealing end cap and lower sealing end cap) at the end of the first separation tower pipe, screws can be used to pass through the sealing end cap and be screwed into the first threaded holes at the ends of the first rib on the outer wall of the first separation tower pipe. The assembly of the first separation tower pipe and the external appropriate sealing end cap is also very simple. In addition, the first separation tower pipe, the second separation tower pipe and the oxygen storage tank as a whole can be produced by die extrusion processing, and the required length can be cut according to the demand. After cutting the required length, as long as the first threaded holes are formed at the two free ends of the first rib on the outer wall of the first separation tower pipe, the processing is very convenient.

[0019] Furthermore, the number of the first convex strips is two, and the two first convex strips are respectively located at two corner positions on the outer wall of the first separation tower tube.

[0020] Therefore, when a suitable sealing end cover is installed at the end of the first separation tower tube, two screws respectively pass through the sealing end cover and are screwed into the first threaded holes at the ends of the first convex strips at two corner positions on the outer wall of the first separation tower tube, ensuring that the end of the first separation tower tube is firmly installed with the sealing end cover and guaranteeing the sealing performance.

[0021] Furthermore, second convex strips are arranged on the outer wall of the second separation tower tube along its length direction, and second threaded holes for fixing with an external sealing end cover are respectively arranged at two ends of the first convex strips.

[0022] Therefore, when a suitable sealing end cover (upper sealing end cover and lower sealing end cover) is installed at the end of the second separation tower tube, screws can be used to pass through the sealing end cover and be screwed into the second threaded holes at the ends of the second convex strips on the outer wall of the second separation tower tube. The assembly of the second separation tower tube and the suitable external sealing end cover is also very simple. In addition, the first separation tower tube, the second separation tower tube, and the oxygen storage tank can be integrally produced by die extrusion processing, and the required length can be cut according to requirements. After cutting the required length, only the second threaded holes need to be formed at the two free ends of the second convex strips on the outer wall of the second separation tower tube, and the processing is very convenient.

[0023] Furthermore, the number of the second convex strips is two, and the two second convex strips are respectively located at two corner positions on the outer wall of the second separation tower tube.

[0024] Therefore, when a suitable sealing end cover is installed at the end of the second separation tower tube, two screws respectively pass through the sealing end cover and are screwed into the second threaded holes at the ends of the second convex strips at two corner positions on the outer wall of the second separation tower tube, ensuring that the end of the second separation tower tube is firmly installed with the sealing end cover and guaranteeing the sealing performance.

[0025] Furthermore, third convex strips are arranged on the outer wall of the oxygen storage tank along its length direction, and third threaded holes for fixing with an external sealing end cover are respectively arranged at two ends of the third convex strips.

[0026] Therefore, when a suitable sealing end cover (upper sealing end cover and lower sealing end cover) is installed at the end of the oxygen storage tank, screws can be used to pass through the sealing end cover and be screwed into the third threaded holes at the ends of the third convex strips on the outer wall of the oxygen storage tank. The assembly of the oxygen storage tank and the suitable external sealing end cover is also very simple. In addition, the first separation tower tube, the second separation tower tube, and the oxygen storage tank can be integrally produced by die extrusion processing, and the required length can be cut according to requirements. After cutting the required length, only the third threaded holes need to be formed at the two free ends of the third convex strips on the outer wall of the oxygen storage tank, and the processing is very convenient.

[0027] Further, the number of the third convex strips is four, and the four third convex strips are respectively located at the four corner positions of the outer wall of the oxygen storage tank.

[0028] Therefore, when a sealing end cover is installed at the end of the oxygen storage tank, four screws respectively pass through the sealing end cover and are screwed into the third threaded holes at the ends of the third convex strips at the four corner positions on the outer wall of the oxygen storage tank, ensuring that the end of the oxygen storage tank is firmly installed with the sealing end cover and guaranteeing the sealing performance.

[0029] Further, the ends of the first separation tower pipe, the second separation tower pipe, and the oxygen storage tank on the same side are flush.

[0030] Therefore, the first separation tower pipe, the second separation tower pipe, and the oxygen storage tank as a whole can be produced by die extrusion processing. According to the required length, they can be integrally cut along the direction perpendicular to the length direction of the first separation tower pipe, the second separation tower pipe, and the oxygen storage tank, and the ends of the cut first separation tower pipe, second separation tower pipe, and oxygen storage tank can be flush, which is very convenient for processing.

[0031] Further, the first separation tower pipe, the second separation tower pipe, and the oxygen storage tank are integrally formed from aluminum.

[0032] Therefore, according to the characteristics of aluminum extrusion, the interval size between the first separation tower pipe and the second separation tower pipe is made to be able to form an oxygen storage tank with the required size. The first separation tower pipe, the second separation tower pipe, and the oxygen storage tank as a whole can be produced by die extrusion processing, and the required length can be cut according to the requirements, which is very convenient for processing.

The oxygen storage tank 3 with a quadrilateral cross-section can effectively utilize the space size between the first separation tower pipe 1 and the second separation tower pipe 2.
