Description

Technical Field

[0001] The utility model relates to the technical field of oxygen concentrators, specifically to oxygen concentrator compressor technology, and in particular to a compressor noise reduction component and an oxygen concentrator. Background Art

[0002] An oxygen concentrator is a type of machine that produces oxygen. Its principle is to use air separation technology. First, the air is compressed at a high density, and then the different condensation points of the various components in the air are used to separate the gas and liquid at a certain temperature. Then, it is distilled to separate it into oxygen and nitrogen. In general, since it is mostly used to produce oxygen, people are accustomed to calling it an oxygen concentrator. Oxygen concentrators are usually equipped with a compressor for use.

[0003] During the use of the oxygen concentrator, it will generate a lot of noise. The noise mainly comes from the suction and closing sound of the compressor and solenoid valve and the nitrogen exhaust sound. Currently, the most common method to reduce compressor noise is to use a compressor cover to reduce noise. However, due to the reasons of the air path and fan, there will be many holes on the compressor cover, and these holes cannot be well sealed; the noise reduction effect is not ideal, which is not conducive to the use of the oxygen concentrator.

[0004] The utility model specially designs a compressor noise reduction component to solve the technical problem that the existing compressor cover has poor sealing performance resulting in poor noise reduction effect.

[0053] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0054] During the use of the oxygen concentrator, it will generate a lot of noise. The noise mainly comes from the suction and closing sound of the compressor and solenoid valve and the nitrogen exhaust sound. Currently, the most common method to reduce compressor noise is to use a compressor cover to reduce noise. However, due to the reasons of the air path and fan, there will be many holes on the compressor cover, and these holes cannot be well sealed; the noise reduction effect is not ideal, which is not conducive to the use of the oxygen concentrator.

[0055] The defects in the existing solutions are the results obtained by the inventors after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this article should be the contributions made by the inventors to this disclosure during the disclosure process.

[0056] Based on the above research, an embodiment of the present disclosure provides a compressor noise reduction component, which forms an air intake duct on the outer side of the compressor cover through the air intake duct cover 2 and the fan cover 8. The fan 9 is a turbo fan, and its air outlet faces the air inlet of the compressor cover. Its function is to blow external air into the compressor cover through the air intake duct. Noise sources such as the compressor and fan 9 are all in the compressor cover, and the compressor cover is well sealed. The noise of the compressor and fan 9 is isolated, thereby achieving a better noise isolation effect.

[0057] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0058] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. In addition, in the drawings, the thickness of components may be exaggerated or reduced in order to effectively describe the technical content.

[0059] like Figures 1 to 4 As shown, at least one embodiment provides a compressor noise reduction component, including: a compressor cover, for accommodating a compressor 4, with an air inlet on the top thereof adapted to the fan outlet; a fan cover 8, for accommodating a fan 9, and located above the compressor cover; an air intake duct cover 2, located on one side of the compressor cover, and connected to one side of the fan cover 8; and an air intake duct is formed between the air intake duct cover 2, the fan cover 8 and the outer side surface of the compressor cover, and external air is blown into the compressor cover by the fan 9 through the air intake duct.

[0060] Specifically, the compressor noise reduction component of this embodiment forms an air intake duct on the outer side of the compressor cover through the air intake duct cover 2 and the fan cover 8. The fan 9 is a turbo fan, and its air outlet faces the air inlet of the compressor cover. Its function is to blow external air into the compressor cover through the air intake duct. Noise sources such as the compressor and fan 9 are all inside the compressor cover, and the compressor cover is well sealed. The noise of the compressor and fan 9 is isolated, thereby achieving a better noise isolation effect.

[0061] In some embodiments, the compressor cover includes: a compressor compartment 5 and a compressor compartment upper cover 10 covering the compressor compartment 5; and an air inlet adapted to the fan outlet is provided on the top of the compressor compartment upper cover 10.

[0062] Specifically, multiple fans 9 can be set up, and the fan 9 blows directly from the top of the compressor compartment to cool the compressor. Since the compressor compartment 5 is well sealed, the fan 9 can effectively blow the hot air in the compressor compartment 5 out of the compressor compartment 5, thereby improving the heat dissipation effect in the compressor compartment 5.

[0063] In some embodiments, a plurality of air inlet holes 21 are provided at the bottom of the air inlet duct cover 2 ; external air enters the air inlet duct through the air inlet holes 21 .

[0064] In some embodiments, the compressor cover also includes: an upper base 6 located below the compressor compartment 5 and a lower base 7 located below the upper base 6; an exhaust channel is provided in the lower base 7, one end of the exhaust channel is provided with a plurality of exhaust holes 72, and the other end is provided with an air outlet 71; and at least one inner side wall of the upper base 6 away from the air outlet 71 is provided with an exhaust outlet 61.

[0065] In some embodiments, at least one approximately orthogonal curved air duct is formed between each exhaust port 61 and the exhaust hole 72 .

[0066] Specifically, in this embodiment, three exhaust ports 61 are set as an example, and a first-level approximately orthogonal bent air duct is formed between the exhaust port 61 opposite to the air outlet 71 and the exhaust hole 72; and the other two oppositely set exhaust ports 61 and the exhaust hole 72 are bent at least twice, that is, two-level approximately orthogonal bent air ducts are formed respectively; through the position design of the exhaust port 61, the exhaust hole 72, and the air outlet 71, a bent exhaust channel is formed below the compressor compartment 5, and the bent exhaust channel allows the hot air in the compressor compartment to bend and circulate in the upper base 6 and then be discharged through the exhaust channel, thereby reducing the sound reflection and loss caused by the change in pipeline impedance corresponding to the airflow, thereby effectively reducing the compressor noise.

[0067] Specifically, the external air enters the air inlet duct through each air inlet hole 21 and is finally discharged through the air exhaust duct. Figure 2 Direction F in.

[0068] Specifically, the upper base 6 further includes mounting posts 62 , and a buffer spring 41 is provided between the bottom of the compressor 4 and each mounting post 62 .

[0069] In some embodiments, the compressor noise reduction assembly further includes: an air intake pipe adapter 11 connected to the compressor air intake pipe and an air outlet pipe adapter 12 connected to the compressor air outlet pipe; the air intake pipe adapter 11 and the air outlet pipe adapter 12 are both located in the compressor compartment upper cover 10.

[0070] Specifically, the compressor noise reduction assembly of this embodiment also arranges the air inlet adapter 11 and the air outlet adapter 12 inside the compressor compartment cover 10, so that all air paths are connected inside the compressor cover, and all pipeline noise sources are also inside the compressor cover. In addition, the compressor cover has a good seal, and the pipeline noise can also be isolated, thereby further improving the noise isolation effect.

[0071] In some embodiments, an air intake silencer compartment 13 is provided above the compressor compartment upper cover 10 corresponding to the air intake pipe adapter 11, which facilitates silencing of the compressor air intake and reduces the compressor air intake noise.

[0072] like Figures 1 to 3 、 Figure 6 As shown, some embodiments further provide an oxygen concentrator, comprising: a compressor 4, a fan 9 and the compressor noise reduction assembly as described above.

[0073] Specifically, the specific structure and working principle of the compressor noise reduction component can be found in the above content and will not be elaborated here.

[0074] In some embodiments, the oxygen concentrator further includes: a heat dissipation pipe 3, a heat dissipation pipe solenoid valve group and a molecular sieve 1; the heat dissipation pipe 3 is located in the air inlet duct and close to the side of the compressor compartment 5; and one end of the heat dissipation pipe 3 is connected to the air outlet pipe adapter 12, and the other end thereof is connected to the molecular sieve 1 via the heat dissipation pipe solenoid valve group.

[0075] In the existing compressor cover technology, the heat dissipation pipe is usually placed inside the compressor cover to cool down by using a fan to blow directly into the heat dissipation pipe. Since the temperature inside the compressor cover is too high, and the heat dissipation pipe is limited in capacity and length due to the limited compressor cover, the heat dissipation effect is not ideal. In order to more effectively reduce the temperature of the air discharged from the compressor, in the technology of the compressor noise reduction component designed in the above embodiment, the heat dissipation pipe 3 is designed on the outer side of the compressor compartment 5. Since there is enough space on the side of the compressor compartment 5, the heat dissipation pipe 3 can be made longer, which has a better heat dissipation effect. The heat dissipation pipe 3 covers the air intake duct connected to the fan 9. The fan 9 absorbs the heat generated by the molecular sieve 1, the heat dissipation pipe solenoid valve group and the heat dissipation pipe 3, and the heat from the molecular sieve 1, the heat dissipation pipe solenoid valve group and the heat dissipation pipe 3 can be quickly taken away through the air intake duct, greatly improving the heat dissipation effect.

[0076] like Figure 4 and Figure 5 As shown, some embodiments further provide an upper base 6 for noise reduction, comprising: a concave structure, at least one inner wall of which is provided with an air outlet 61; and mounting columns 62 for mounting the compressor 4 are also provided at each corner of the concave structure.

[0077] like Figure 4 and Figure 5As shown, some embodiments further provide a base assembly for noise reduction, comprising: a lower base 7 for noise reduction and an upper base 6 for noise reduction as described above; wherein the lower base 7 for noise reduction is provided with an exhaust channel, one end of the exhaust channel is provided with a plurality of exhaust holes 72, and the other end is provided with an air outlet 71; and the air outlet 61 is provided on at least one inner side wall of the concave structure away from the air outlet 71.

[0078] In some embodiments, at least one approximately orthogonal curved air duct is formed between each exhaust port 61 and the exhaust hole 72 .

[0079] Specifically, the specific structure and working principle of the lower base 7 for noise reduction and the upper base 6 for noise reduction can be referred to the above content and will not be described in detail here.

[0080] Some embodiments further provide an oxygen concentrator, comprising: an upper base 6 for noise reduction, which includes a concave structure, at least one inner side wall of the concave structure is provided with an exhaust port 61; a lower base 7 for noise reduction, which is provided with an exhaust channel, one end of the exhaust channel is provided with a plurality of exhaust holes 72, and the other end is provided with an air outlet 71; wherein, at least one level of approximately orthogonal curved air duct is formed between each exhaust port 61 and the exhaust hole 72.

[0081] In some embodiments, at least one approximately orthogonal curved air duct is formed between each exhaust port 61 and the exhaust hole 72 .

[0082] Specifically, the specific structure and working principle of the lower base 7 for noise reduction and the upper base 6 for noise reduction can be referred to the above content and will not be described in detail here.
