Description

Technical Field

[0001] The utility model relates to the technical field of oxygen production, and in particular provides a heat dissipation and silencer channel structure for an oxygen generator. Background Art

[0002] An oxygen generator is a device used to produce oxygen. It usually uses molecular sieve adsorption method to produce oxygen. The principle is mainly to use the selective adsorption effect of molecular sieve on molecules of different sizes. The molecular sieve is loaded in the oxygen generator. When the air is compressed and enters the molecular sieve adsorption tower, small molecules such as nitrogen are adsorbed on the molecular sieve, and large molecules such as oxygen are discharged through the molecular sieve adsorption tower, thereby achieving the separation of oxygen and nitrogen. The molecular sieve discharges the adsorbed nitrogen back to the ambient air when decompressed, and can adsorb nitrogen and produce oxygen when pressurized next time. The whole process is a periodic dynamic cycle process.

[0003] Since various components are combined in the oxygen concentrator to collect, filter and compress air, not only does the compressor produce sound when it is working, but the air also produces friction and vibration sounds when passing through the pipes, filters and other parts of the oxygen concentrator, and the radiator also produces noise when it is working, which can easily interfere with the user. The existing oxygen concentrator usually adds a shock-absorbing rubber pad to the bottom of the compressor and wraps it with sound insulation material. However, wrapping too much sound insulation material will affect the heat dissipation effect, and wrapping too little will affect the sound insulation effect. For this reason, we propose a heat dissipation and silencer channel structure for an oxygen concentrator. Utility Model Content

[0004] In order to solve the above problems existing in the prior art, the utility model provides a heat dissipation and silencer channel structure for an oxygen concentrator.

[0005] The above-mentioned problem of the utility model is solved by the following technical solutions:

[0006] It includes an oxygen production component arranged inside the shell, wherein an air duct is arranged inside the oxygen production component and is connected with an air inlet and an air outlet on the shell;

[0007] A fan is also arranged in the shell, an air outlet channel is formed between the air outlet of the fan and the air outlet of the shell, and the compressor of the oxygen production component is located in the air outlet channel.

[0008] By adopting the above solution, the moving airflow can fully contact the compressor, thereby taking away most of the heat on the compressor and quickly cooling the inside of the oxygen concentrator.

[0009] The above technical solution is further configured as follows: the air outlet channel is provided with a heat dissipation zone and a silencer zone along the air outlet direction and the air outlet path; the heat dissipation zone wraps around the compressor.

[0014] The above technical solution is further configured as follows: the silencer hole and the air outlet portion of the heat dissipation zone are staggered.

[0015] By adopting the above technical solution, the two air outlet positions are staggered, and the airflow needs to turn during the movement to reach the next outlet, thereby blocking the airflow and reducing noise.

[0016] The above technical solution is further configured as follows: the airflow movement paths of the heat dissipation zone and the silencer zone are arranged at an angle.

[0026] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0027] like Figure 1-3 As shown, the following embodiment discloses a heat dissipation and silencer channel structure for an oxygen concentrator.

[0028] It includes an oxygen production component arranged inside the housing 100, wherein an air duct is arranged inside the oxygen production component and is connected with an air inlet 102 and an air outlet 103 on the housing 100;

[0029] A fan 200 is further disposed in the housing 100 , an air outlet passage is formed between the air outlet of the fan 200 and the air outlet of the housing 100 , and the compressor 300 of the oxygen production assembly is located in the air outlet passage.

[0030] The above is the basic solution of this embodiment.

[0031] Specific reference Figure 1 As shown, in this embodiment, the oxygen production component includes a molecular sieve 400 and a compressor 300. Its principle is to use air separation technology. First, the air is compressed at a high density, and then the different condensation points of various components in the air are used to separate the gas and liquid at a certain temperature, and then distilled to separate them into oxygen and nitrogen. The shell 100 is provided with an oxygen outlet pipe 101 for passing oxygen out.

[0032] During the oxygen production process, the compressor 300 and the molecular sieve 400 generate a large amount of heat and noise when working, causing the entire oxygen generator to heat up and make a lot of noise. In this embodiment, a sound-absorbing layer is provided on the inner wall of the shell 100 to absorb the noise and reduce the noise of the machine; however, due to the provision of the sound-absorbing layer, the heat dissipation is hindered to a certain extent, resulting in a high ambient temperature of the shell 100. Therefore, a fan 200 is provided inside the shell 100 to drive the air inside to form an airflow, and the heat is taken out from the air outlet 103 of the shell 100 along with the airflow, thereby reducing the internal heat of the shell 100.

[0033] Moreover, most of the heat in the shell 100 comes from the compressor 300. Therefore, the compressor 300 is set in the air outlet channel. After the air flow is generated in the fan 200, it moves along the air outlet channel. During the movement, it contacts the compressor 300 and directly takes away the heat on the surface of the compressor 300, thereby cooling the compressor 300.

[0034] Preferably, in this embodiment, in order to increase the contact between the airflow and the compressor 300, the air outlet channel is provided with a heat dissipation zone and a silencer zone along the air outlet direction and the air outlet path; the heat dissipation zone is provided to wrap the compressor 300.

[0035] Based on the above arrangement, the moving airflow can fully contact the compressor 300, thereby taking away most of the heat on the compressor 300 and rapidly cooling the interior of the oxygen concentrator.

[0036] In this embodiment, the specific positions of the air outlet channel and the compressor 300 are arranged as follows: the heat dissipation area includes a first air duct a, and the first air duct a is located outside the compressor 300;

[0037] An air outlet is disposed below the compressor 300 .

[0038] Specific reference Figure 2 As shown, in this embodiment, the fan 200 is arranged directly above the compressor 300, and a first air duct a is formed on all four sides of the compressor 300. The air outlet is arranged below the compressor 300, and the horizontal interface of the air outlet is smaller than the horizontal cross-section of the compressor 300. That is, if the moving airflow is to be blown out from the air outlet, the moving airflow on the side needs to pass under the compressor 300, thereby completely wrapping the compressor 300.

[0039] Specifically, in this embodiment, a cover body 310 is provided outside the compressor 300 , the first channel is located between the cover body 310 and the outer surface of the compressor 300 , and the air outlet portion is an air outlet hole 311 provided at the bottom of the cover body 310 .

[0040] In this embodiment, the specific implementation of the silencing zone is as follows: the silencing zone is located between the air outlet portion and the air outlet 103, and includes a first silencing chamber b and a second silencing chamber c; a silencing insulation layer 500 is provided between the first silencing chamber b and the second silencing chamber c.

[0041] Preferably, the sound-absorbing insulating layer 500 is provided with sound-absorbing holes 501 .

[0042] Specific reference Figure 3 As shown, the silencing chamber is located below the compressor 300 and connected to the air outlet 311; the silencing insulation layer 500 separates the first silencing chamber b from the second silencing chamber c, and a silencing hole 501 is provided on one side thereof;

[0043] After the moving airflow is blown out from the first air duct a, it enters the first silencer chamber b. The part of the silencer layer 500 located in the first silencer chamber b reduces the noise of the airflow. When the moving airflow enters the second silencer chamber c through the silencer hole 501, the silencer hole 501 reduces the noise of the moving airflow again, and the noise reduction force is greater than the absorption of the silencer layer 500. After the airflow moving in the second silencer chamber c is reduced for the third time by the silencer layer 500, it is blown out from the air outlet 103 of the shell 100.

[0044] Preferably, in this embodiment, the muffler hole 501 and the air outlet position of the first air duct a are staggered.

[0045] Specific reference Figure 2 and Figure 3 As shown, the first silencer chamber b and the second silencer chamber c are arranged horizontally in an upper and lower position, and the silencer hole 501 is arranged on one side separated by the two silencer chambers, that is, when the moving airflow enters the second silencer chamber c from the first silencer chamber b, it needs to make a 180-degree turn to block and reduce the noise of the airflow again.

[0046] Based on the above arrangement, in this embodiment, the airflow movement paths of the heat dissipation zone and the silencer zone are arranged at an angle.

[0047] Preferably, in this embodiment, the angle is 90 degrees.

[0048] Specific reference Figure 2 As shown, the fan 200 is arranged at the upper end of the compressor 300 cover, and the blowing direction is downward toward the compressor 300, so the airflow movement direction of the first air duct a is nearly vertical from top to bottom; and the first silencer chamber b and the second silencer chamber c are horizontally arranged, and the airflow movement direction inside is horizontal; when the air flows through the first air duct a into the first silencer chamber b, it needs to make a 90-degree turn, and the turning process is the process of blocking and reducing the noise of the airflow.

[0049] In summary, in this embodiment, when the airflow is moving, in addition to the multiple silencers that are vertically arranged tightly inside the shell 100 to silence it, multiple turning structures are also provided to silence it, and the silencer holes 501 silence the airflow with great force, thereby minimizing the noise inside the shell 100 and making the oxygen concentrator work quietly.

[0050] In this embodiment, in order to further increase the sound-absorbing effect, the sound-absorbing insulation layer 500 includes a top and two side portions, and the two side portions are located on the inner wall of the second sound-absorbing chamber c to silence the airflow in the second sound-absorbing chamber c.

[0051] Specific reference Figure 2 As shown, the two side portions are arranged as the two sides of the airflow, and are provided with silencer holes 501 to silence the small amount of airflow overflowing to the side portions.

[0052] Preferably, in this embodiment, the sound-absorbing layer located on the inner wall of the shell 100 and the inner wall of the cover body 310, as well as the sound-absorbing insulation layer 500 in the sound-absorbing area are all configured as sound-absorbing cotton.

[0053] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
