Preferably, the upper surface and two side surfaces of the second part of the inverted U-shaped body 15 are provided with a diversion hole 4. The sound insulation board sheet metal 2 is provided with a first opening 9, and the first opening faces the upper surface of the first part. The sound insulation board sheet metal 2 is installed directly above the inverted U-shaped body 15, and the bottom of the sound insulation board sheet metal 2 is closely attached to the sound insulation baffle 3. The sound insulation board sponge 1 is provided with a second opening 10, and the sound insulation board sponge 1 is matched and installed on the sound insulation board sheet metal 2, and the first opening 9 is aligned with the second opening 10.

[0053] Figure 2-4 The above is shown in more detail Figure 1 The structure of the noise reduction component 6 shown in FIG. Figure 2-4 As shown, the first end 16 of the inverted U-shaped body 15 of the noise reduction component 6 is also connected to an adapter body 8, which is designed according to the mounting structure inside the base body 5. The adapter body 8 is formed integrally with the inverted U-shaped body 15, and the adapter body 8 and the inverted U-shaped body 15 are adapted and installed in the base body 5. In the second part between the plane where the sound insulation baffle 3 is located and the plane where the second end 17 is located, a mounting hole 11 is also provided on the upper surface of the second part adjacent to the second end 17. When the inverted U-shaped body 15 is mounted to the base body 5, it is fixedly connected to the base body 5 by screwing a cross pan head screw into the mounting hole 11.

[0054] Preferably, in the above Figure 1-4 In the noise reduction component 6 shown in Figure 1-4 As shown, the two sides of the sound insulation baffle 3 can extend side wings 13 respectively in the direction of the second end 17. The diverter hole 4 can adopt a plurality of square diverter holes, and the plurality of square diverter holes are arranged in the transverse direction and the longitudinal direction to form a mesh structure. Of course. Alternatively, the diverter hole 4 can also adopt the arrangement of a plurality of circular diverter holes or the arrangement of a plurality of triangular diverter holes.

[0055] Figure 5-6 Shown in more detail Figure 1 The structure of the base body 5 shown in FIG. Figure 5-6 As shown in the figure, the interior of the base body 5 is a rectangular structure 14. An exhaust hole 12 is provided on the side of the base body 5. When the noise reduction component 6 is fixedly installed in the base body 5, the exhaust hole 12 is connected to the inverted U-shaped opening of the inverted U-shaped body 15 at the first end 16, and the noise after the noise reduction through the diverter hole 4 on the second part of the inverted U-shaped body 15 is discharged. At the same time, when the noise reduction component 6 is fixedly installed in the base body 5, at least one of the two side surfaces of the inverted U-shaped body 15 of the noise reduction component 6 will form an air duct with the rectangular structure 14.

[0056] In the structure shown above, preferably, the sound insulation board sheet metal 2 is made of galvanized sheet; the base body 5 and the noise reduction component 6 are both injection molded from ABS material.

[0057] When the above-mentioned noise reduction base structure is in use, the anti-slip pad 7 is installed on the bottom surface outside the base body 5, the adapter body 8 and the inverted U-shaped body 15 of the noise reduction component 6 are adapted and installed in the base body 5, and the inverted U-shaped body 15 is fixedly installed in the base body 5 through the mounting hole 11, the sound insulation board sheet metal 2 is installed directly above the inverted U-shaped body 15 and the bottom of the sound insulation board sheet metal 2 is tightly attached to the sound insulation baffle 3, the sound insulation board sponge 1 is matched and installed on the sound insulation board sheet metal 2, the four springs on the sound insulation board sheet metal 2 pass through the four circular holes 18 on the sound insulation board sponge 1, and the compressor of the oxygen generator is supported on the four springs extending above the sound insulation board sponge 1. When the whole part of the oxygen concentrator is on the noise reduction base, the sound insulation board sponge 1 and the sound insulation board sheet metal 2 isolate the noise of the compressor of the oxygen concentrator, that is, the sound insulation board sponge 1 and the sound insulation board sheet metal 2 will reduce part of the noise, and the noise that is not eliminated and isolated will continue to be discharged downward to the noise reduction component 6 through the second opening 10 on the sound insulation board sponge 1 and the first opening 9 on the sound insulation board sheet metal 2, and the noise reduction component 6 will continue to eliminate and isolate the discharged noise. Specifically, the noise that is not eliminated and isolated will be discharged downward to the first part of the inverted U-shaped body 15, and the noise will flow to the sound insulation baffle 3 to isolate. The sound baffle 3 blocks the intensity of the noise, and the blocked noise will flow along the air duct formed between the side of the noise reduction component 6 and the rectangular structure 14 inside the base body 5 to the diverter hole 4 on the second part of the inverted U-shaped body 15 of the noise reduction component 6. The diverter hole 4 eliminates the frequency and intensity of the noise again, generating relatively small noise, and then enters the inverted U-shaped groove of the inverted U-shaped body 15 and flows along the inverted U-shaped groove to the exhaust hole 12 connected to the inverted U-shaped opening at the first end 16 of the inverted U-shaped body 15, so that the remaining noise is discharged through the exhaust hole 12 to achieve the noise reduction effect. In addition, the noise reduction base can also automatically adjust the strength of the noise eliminator according to the pressure of the oxygen generator system to achieve the best noise reduction effect.

[0058] In addition, the present invention also provides an oxygen concentrator, comprising the above-mentioned noise reduction base applied to the oxygen concentrator, so that the oxygen concentrator can optimally reduce the noise eliminated by the oxygen concentrator through the noise reduction base of the above structure.

[0059] In summary, the present invention achieves the change of the intensity and frequency of the noise through the noise reduction component of the injection molding structure, and reduces the intensity of the sound waves that hit the sound insulation baffle, thereby reducing the noise generated by the oxygen concentrator equipment, and the noise reduction effect is significant. When the noise reduction base of the present invention is used, the mute effect is better, the heat dissipation efficiency is higher, the whole machine is not easy to be damaged by overheating, and the service life is extended.
