Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] Combined with appendix Figure 1-4 An air compressor for oxygen production includes an air filter 2, an air compressor 4, and a pressure tank 5. The pressure tank 5 requires a pressure gauge and other structures, which is a common compressor structure and will not be described in detail. The air compressor 4 is connected to an extraction pipe 6 and a first outlet pipe 7 communicating with the pressure tank 5. The extraction pipe 6 is connected to a main air pipe 8, and the main air pipe 8 is connected to a first auxiliary air pipe 9 connected to the air filter 2. The pressure tank 5 is connected to an exhaust valve pipe 16 extending to the outside. The air compressor 4 and the air tank 5 are surrounded by a silent sealing box 1. The silent sealing box 1 has a sealing cavity 3 inside, and a main sound-absorbing cotton 15 is connected to the inside of the silent sealing box 1. That is, the noisy air compressor 4 is placed inside the sealing cavity 3. Noise is absorbed by the main sound-absorbing cotton 15 to prevent noise leakage. The inner side of the silent sealed box 1 is provided with a vacuum sound insulation layer 10, which provides two-stage noise reduction to minimize noise. A pressure sensor 14 is connected inside the vacuum sound insulation layer 10. The main air pipe 8 is connected to a second auxiliary air pipe 11 that extends into the vacuum sound insulation layer 10. A first electric control valve 12 and a second electric control valve 13 are respectively connected to the first auxiliary air pipe 9 and the second auxiliary air pipe 11. In actual use, because there will be pipes and lines connected to the vacuum sound insulation layer 10, the second auxiliary air pipe 11 is set up. When the pressure sensor 14 senses that the internal pressure is low, it activates the second electric control valve 13 to extract the internal air and ensure vacuum operation.

[0022] The top of the silent sealing box 1 is provided with a convex mounting groove 17, and a convex soundproof maintenance cover 18 is fixedly connected inside the convex mounting groove 17. A secondary sound-absorbing cotton 27 is connected to the bottom of the convex soundproof maintenance cover 18. The secondary sound-absorbing cotton 27 at the bottom of the convex soundproof maintenance cover 18 further enhances the sound absorption effect. A temperature sensor 25 is connected inside the silent sealing box 1. A heat dissipation exhaust pump 19 is connected to the bottom of the convex soundproof maintenance cover 18. The heat dissipation exhaust pump 19 is connected to an air inlet pipe 20 extending to the outside and inside, and a second air outlet pipe 21. The convex soundproof maintenance cover 18 is connected to a heat dissipation pipe 22 on one side. The air inlet pipe 20 and the heat dissipation pipe 22 are respectively connected to a third solenoid valve 23 and a fourth solenoid valve 24. When the internal temperature is high, the heat dissipation pump 19, the third solenoid valve 23 and the fourth solenoid valve 24 are activated to draw in external air and then discharge excess hot air through the heat dissipation pipe 22, thereby achieving the effect of internal heat dissipation. The convex mounting groove 17 and the convex soundproof maintenance cover 18 are both provided with fastening bolt holes 26. A sealing gasket 28 is connected to the inner side of the convex mounting groove 17.

[0023] The air filter 2 has a mesh inlet 31 connected to one side of its bottom. A cloth filter cylinder 32 is connected to the bottom of the air filter 2. The cloth filter cylinder 32 is a circular mesh cylinder covered with a cloth cover, such as non-woven fabric, to filter dust. A desiccant adsorption layer 33 is connected to the top of the air filter 2. The desiccant adsorption layer 33 prevents water molecules from accumulating inside the pressure tank 5. The first auxiliary air guide pipe 9 is connected to the top of the desiccant adsorption layer 33. A first sealing maintenance door 29 and a second sealing maintenance door 30 are connected to the outside of the air filter 2, respectively cooperating with the cloth filter cylinder 32 and the desiccant adsorption layer 33. Regular cleaning and maintenance of the cloth filter cylinder 32 and the desiccant adsorption layer 33 can be performed through the first sealing maintenance door 29 and the second sealing maintenance door 30.
