Technical Field

[0001] The utility model relates to the technical field of oxygen production equipment, in particular to an oxygen production machine with a noise reduction structure. Background Art

[0002] Oxygen generator 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 components in the air are used to separate the gas and liquid at a certain temperature, and then further distilled to obtain oxygen.

[0003] The oxygen concentrator will generate vibration when working, and this vibration will also generate noise. If it is not properly shock-absorbing, it will affect the noise level of the equipment. At the same time, the oxygen concentrator needs to continuously draw outside air into the equipment, and the air contains a lot of dust. The air inlet of the air compressor is easily blocked by dust, fluff, etc., which prevents air from entering, thus affecting the oxygen production effect. Summary of the invention

[0012] 1. The operator sets a horizontal partition substrate, and sets sound insulation cotton boards on both sides of the partition substrate. According to the number and width of the oxygen production components, the operator selects the sound insulation cotton boards of corresponding width, and wraps both sides of the equipment with the sound insulation cotton boards to reduce the vibration amplitude of the equipment during operation. At the same time, the threaded rod is used to drive the internal thread cover to move horizontally, and then the position of the internal thread cover and the partition substrate is adjusted to improve the stability of clamping and positioning of the equipment, and at the same time facilitate the rapid disassembly and replacement of the components.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

The noise reduction mechanism 5 reduces the vibration amplitude of the oxygen concentrator during operation, thereby reducing the noise generated during the operation of the equipment. A cleaning mechanism 15 is arranged on one side of the oxygen concentrator shell 1, and the cleaning mechanism 15 regularly cleans the air intake part to reduce the fan noise generated by the oxygen concentrator during operation due to blockage of the air intake.

[0023] In this embodiment, the noise reduction mechanism 5 includes a threaded rod 6, an internal threaded tube 7, a partition substrate 8, a sound insulation cotton board 9 and a guide slide rod 10. The threaded rod 6 is arranged at one end of the control handle 2, and the outer side of the threaded rod 6 is connected to the internal threaded tube 7, and the other end of the internal threaded tube 7 is connected to the partition substrate 8. Sound insulation cotton boards 9 are arranged on both sides of the partition substrate 8. The guide slide rods 10 are symmetrically distributed on the outer side of the partition substrate 8. The partition substrate 8 is driven by the internal threaded tube 7 to move laterally, thereby limiting and squeezing one side of the device.

[0024] In this embodiment, the partition substrate 8 is connected to the inner end of the oxygen production shell 1 through symmetrically distributed guide slide bars 10. The guide slide bars 10 guide both sides of the partition substrate 8 to prevent the partition substrate 8 from being displaced.

[0025] In this embodiment, fastening holes 16 are symmetrically opened on the outer side of the partition substrate 8, and one side of the sound insulation cotton board 9 is positioned through the fastening holes 16 to complete the positioning processing of the sound insulation cotton boards 9 with different thicknesses.

[0026] In this embodiment, the cleaning mechanism 15 includes a sealing cover plate 3, an air inlet hole 4, an air filter plate 12, a cleaning brush 13 and a dust collecting groove 14. The sealing cover plate 3 is arranged on one side of the oxygen generator housing 1, and the outer side of the sealing cover plate 3 is provided with air inlet holes 4 at equal intervals. A cleaning brush 13 is arranged on one side of the air inlet hole 4, and an air filter plate 12 is arranged on one side of the cleaning brush 13. A dust collecting groove 14 is connected to one side of the bottom end of the sealing cover plate 3, and the inner side of the air filter plate 12 is cleaned by the cleaning brush 13, and dust is collected by the dust collecting groove 14.

[0027] In this embodiment, the air filter plate 12 is attached to one side of the partition substrate 8, and one side of the air inlet is blocked by the air filter plate 12 to prevent dust from directly entering the interior of the device.

[0028] This oxygen concentrator with noise reduction structure has the following working contents in practical application:

[0029] Step 1: The operator first positions the screws symmetrically arranged at the top of the sealing cover plate 3 with the top of the oxygen production housing 1, completes the disassembly of the sealing cover plate 3, and directly draws the external air into the interior of the oxygen production housing 1 through the air compressor, separates the gas types in the air through the molecular sieve tower, and then directly introduces the separated oxygen into the interior of the air storage tank, and then directly discharges the separated oxygen through the electric valve;

[0030] Step 2: When the oxygen production component 11 including (air compressor, molecular sieve tower, electric valve and air storage tank) is installed on the left and right sides of the partition substrate 8, the sound insulation cotton board 9 of different lengths or widths is selected to fit with the partition substrate 8 according to the specific size of the oxygen production component 11, and the sound insulation cotton board 9 is connected to the partition substrate 8 through the fastening hole 16. The operator holds the control handle 2 on one side and drives the threaded rod 6 to rotate through the control handle 2;

[0031] Step 3: The threaded rod 6 drives the internal threaded tube 7 to expand and contract horizontally, thereby completing the expansion of the partition substrate 8 and the sound insulation cotton board 9, squeezing one side of the equipment through the sound insulation cotton board 9, and then wrapping the surface of the equipment on the other side. When the air compressor, molecular sieve tower, electric valve and air storage tank are in operation, the sound insulation cotton board 9 is used to reduce the vibration amplitude of the equipment during operation;

[0032] Step 4: After the equipment has been running for a long time, it can be maintained and replaced. At the same time, the threaded rod 6 drives the internal threaded tube 7 to extend and retract laterally, so that the sound insulation cotton board 9 moves left and right along with the partition substrate 8. The surface of the sound insulation cotton board 9 is repeatedly cleaned by the cleaning brush 13. The cleaned dust directly falls into the dust collection tank 14, thereby completing the cleaning of the filter holes on the surface of the sound insulation cotton board 9.

[0033] Therefore, the embodiments disclosed above are only illustrative in all aspects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
