Description

Technical Field

[0001] The utility model relates to the technical field of oxygen generators, in particular to a high-efficiency oxygen generator. Background Art

[0002] As people's living standards continue to improve, their demand for health is gradually increasing, and oxygen inhalation will gradually become an important means of home rehabilitation, so home oxygen concentrators are becoming more and more common. There are many types of home oxygen concentrators on the market, but many of them have unreasonable designs and arrangements of the internal components of the whole machine, resulting in slow heat dissipation, thereby reducing the oxygen production efficiency and shortening the life of the various components of the oxygen concentrator. Summary of the invention

[0003] The internal layout of existing oxygen generators is disorderly, resulting in low oxygen production efficiency and shortened service life of various components.

[0004] In view of the above problems, a high-efficiency oxygen generator is proposed. By arranging the molecular sieve assembly at the first air inlet, the temperature of the molecular sieve can be effectively conducted out, so as to avoid the molecular sieve having too high a temperature during operation and affecting the efficiency of nitrogen and oxygen separation, thereby increasing the life of the molecular sieve and improving the oxygen production efficiency. By arranging the filter at the bottom rear side of the second accommodating space, close to the first air inlet, it is ensured that the temperature of the incoming air is the temperature of the outside air, which is conducive to reducing the increase in the temperature of the compressor outlet air, thereby also increasing the life of the molecular sieve and improving the oxygen production efficiency. By arranging the first accommodating cavity and the second accommodating cavity in sequence, the air duct of the oxygen generator flows from left to right, which avoids the hot exhaust gas discharged by the oxygen generator from flowing back to the air inlet again, and ensures that the incoming air is fresh air, which is also conducive to improving the oxygen production efficiency of the oxygen generator.

[0053] The internal layout of existing oxygen generators is disorderly, resulting in low oxygen production efficiency and shortened service life of various components.

[0054] In view of the above problems, a high-efficiency oxygen generator is proposed.

[0061] Furthermore, if Figure 3 The second accommodating space 120 includes a second subspace (not shown in the figure); the second subspace (not shown in the figure) is located at the bottom rear side of the second accommodating space 120 and is used to arrange the filter 305.

[0062] Furthermore, if Figure 3 The third accommodating space 130 includes a third subspace 132; the third subspace 132 is located at the top of the third accommodating space 130, and is connected to the second accommodating cavity 200 through the second air inlet portion 210, and is used for arranging the cooling pipe 306 of the compressor assembly.

[0063] Furthermore, if Figure 3 The first accommodating cavity 100 includes a bottom shell 101 , a top shell 103 , and a side shell 102 ; the bottom shell 101 , the side shell 102 , and the top shell 103 form the first accommodating cavity 100 .

[0064] Furthermore, the first accommodating cavity 100 is a cube or a cylinder.

[0068] Air inlet path:

[0069] After the oxygen concentrator is turned on, cold air enters from the first air inlet 111 on the left, passes through the molecular sieve assembly 301, and then goes up toward the molecular sieve aluminum tube to reach the main circuit board 302, the display circuit board 307, the key circuit board, and the rotary valve assembly, and then passes through the heat dissipation pipe, and blows into the compressor in the second accommodating cavity 200 (compressor cover) through the fan, and then blows out from the first air outlet 131 on the right.

By arranging the filter 305 at the bottom rear side of the second accommodating space 120, close to the first air inlet 111, it is ensured that the temperature of the incoming air is the temperature of the outside air, which is conducive to reducing the increase in the temperature of the compressor outlet air, thereby also increasing the life of the molecular sieve and improving the oxygen production efficiency. By arranging the first accommodating cavity 100 and the second accommodating cavity 200 in sequence, the air duct of the oxygen generator is circulated from left to right, avoiding the hot exhaust gas discharged by the oxygen generator from flowing back to the air inlet again, ensuring that the incoming air is fresh air, which is also conducive to improving the oxygen production efficiency of the oxygen generator.
