Description

Technical Field

[0001] The utility model relates to a shock absorbing component of a special compressor for an oxygen concentrator. Background Art

[0002] An oxygen concentrator is a medical device used to provide pure oxygen to patients with respiratory diseases or other patients who need additional oxygen supply. Oxygen concentrators extract oxygen from the air and remove other gases and impurities, allowing patients to breathe high concentrations of oxygen. In medical, home or commercial use, oxygen concentrators are increasingly used as key equipment for providing assisted breathing or pure oxygen supply. Oxygen concentrators are usually composed of compressors, filters, separation devices, regulators, oxygen storage tanks and other parts, and the core component of the oxygen concentrator is the compressor, which is responsible for compressing air to separate oxygen. The oxygen concentrator can provide different concentrations of oxygen according to the needs of the patient. Generally speaking, doctors will adjust the settings of the oxygen concentrator to provide the appropriate oxygen concentration according to the patient's condition and needs. Oxygen concentrators are widely used in different places such as hospitals, clinics and homes. It can improve the patient's respiratory function and increase the oxygen content in the blood, thereby relieving dyspnea and other symptoms associated with hypoxemia.

[0003] However, traditional oxygen concentrator compressors are usually installed inside the oxygen concentrator and in contact with the shell, which will produce significant vibration and noise during operation. This will not only affect the user experience, but may also cause equipment damage. It will also cause the shell to vibrate, shortening the service life of the entire oxygen concentrator and more likely to have a negative impact on the surrounding environment. Utility Model Content

[0005] Based on the technical problems existing in the background technology, the utility model proposes a shock absorbing assembly for a compressor dedicated to an oxygen concentrator, including a support shock absorbing frame and a fixed base installed inside the oxygen concentrator body outside the compressor;

[0006] The support and damping frame comprises two groups of fixed frames and a damping frame, a plurality of groups of buffer structures are arranged between the fixed frames and the damping frames, the two groups of fixed frames are fixed to the outer shells on both sides of the compressor, the damping frame sleeves are arranged on the outside of the fixed frames, and the bottoms of the two groups of damping frames are installed on the support pads, the two ends of the fixed frames are provided with mounting sleeves, the two sides of the mounting sleeves are provided with moving grooves, the two ends of the damping frame are provided with damping blocks corresponding to the mounting sleeves, the two sides of the damping blocks are provided with moving blocks installed in the moving grooves, and a plurality of springs are installed between the damping blocks and the bottom of the mounting sleeves;

[0007] A buffer plate is provided in the fixed base, the support pad is mounted on the buffer plate, a plurality of buffer springs are mounted on the bottom of the buffer plate, and the other ends of the plurality of buffer springs are mounted on the bottom plate of the fixed base.

[0008] Preferably, each group of the buffer structure includes a support column, the support column is installed on the inner side of the shock absorbing frame, and a sleeve column extends from the end of the support column, a buffer spring 2 is sleeved on the outer side of the sleeve column, and the other end of the buffer spring 2 is fixed to the outer side of the fixing frame.

[0009] Preferably, the inner diameter of the support column is at least larger than the inner diameter of the buffer spring 2, and the inner diameter of the sleeve column is at least smaller than the inner diameter of the buffer spring 2, and the other end of the buffer spring 2 is fixed to the end where the support column and the sleeve column are connected.

[0010] Preferably, the fixed base is further provided with a surrounding plate on the outside of the buffer plate, and an L-shaped baffle is also installed on one side of the fixed base, and the L-shaped baffle and the buffer plate are combined into a semi-enclosed space.

[0013] Compared with the prior art, the shock absorbing component of a compressor dedicated to an oxygen concentrator proposed in the utility model adopts the above technical solution and achieves the following technical effects:

[0014] 1. The utility model reduces the vibration frequency of the connecting parts generated by the compressor when working by installing a supporting shock-absorbing frame on the compressor shell, uses a fixing frame to keep the compressor stable, and then uses a shock-absorbing frame to be sleeved on the outside of the fixing frame. When the compressor vibrates, the whole body together with the fixing frame vibrates on the shock-absorbing frame. Since a buffer structure is connected between the vibration frame and the fixing frame, and a spring is also installed at the connection between the ends of the two, the vibration of the compressor itself can be weakened and transmitted to the shock-absorbing frame, thereby reducing the overall vibration frequency;

[0015] 2. The support and shock-absorbing frame connected to the compressor casing is installed on a fixed base, and a buffer plate is provided inside the fixed base. When the vibration of the compressor is transmitted to the support and shock-absorbing frame, the vibration generated on it will continue to be transmitted to the fixed base connected to the bottom, thereby affecting the oxygen concentrator casing connected to the base. The buffer plate provided on the fixed base can further reduce the vibration impact generated by the compressor. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Reference Figure 1-6 The utility model proposes a shock absorbing assembly for a compressor dedicated to an oxygen concentrator, comprising a support shock absorbing frame 3 and a fixed base 4 installed outside a compressor 2 inside an oxygen concentrator body 1;

[0027] Specifically, the support and damping frame 3 includes two groups of fixed frames 31 and a damping frame 32, and multiple groups of buffer structures 33 are arranged between the fixed frames 31 and the damping frames 32. The two groups of fixed frames 31 are fixed on the outer shells on both sides of the compressor 2, and the damping frames 32 are sleeved on the outside of the fixed frames 31, and the bottoms of the two groups of damping frames 32 are installed on the support pad 34. The two ends of the fixed frames 31 are provided with mounting sleeves 311, and the two sides of the mounting sleeves 311 are provided with moving grooves 312. The two ends of the damping frame 32 are provided with damping blocks 321 corresponding to the mounting sleeves 311, and the two sides of the damping blocks 321 are provided with moving blocks 322 installed in the moving grooves 312, and multiple springs 35 are installed between the damping blocks 321 and the bottom of the mounting sleeves 311.

[0028] In this embodiment, the fixing frame 31 is fixedly sleeved on the outer shell of the compressor 2, and the shock absorbing frame 32 is installed outside the fixing frame 31. The shock absorbing blocks 321 arranged at the two ends of the shock absorbing frame 32 are accommodated therein through the mounting sleeves 311 arranged at the two ends of the fixing frame 31, and the moving blocks 322 arranged at the two ends of the shock absorbing block 321 can just move in the moving grooves 312 opened at the two sides of the mounting sleeve 311, so that the whole shock absorbing block 321 can move in the mounting sleeve 311, and will not move out of the range of the mounting sleeve 311 under the restriction of the moving blocks 322. At the same time, a spring is connected between the bottom of the shock absorbing block 321 and the inside of the mounting sleeve 311, so that the two have a certain resilience when moving, and can greatly absorb the vibration generated when the compressor 2 is working;

[0029] In this embodiment, a plurality of buffer structures 33 are connected between the fixing frame 31 and the shock absorbing frame 32, so that the buffering between the two is more comprehensive. The all-round buffering can ensure that the vibration transmission frequency of the compressor is effectively reduced.

[0030] Reference Figure 4A buffer plate 41 is provided in the fixed base 4, the support pad 34 is installed on the buffer plate 41, a plurality of buffer springs 42 are installed at the bottom of the buffer plate 41, and the other ends of the plurality of buffer springs 42 are installed on the bottom plate of the fixed base 4.

[0031] Reference Figure 7 Each buffer structure 33 includes a support column 331, which is installed on the inner side of the shock absorbing frame 32, and a sleeve column 332 extends from the end of the support column 331. A buffer spring 333 is sleeved on the outer side of the sleeve column 332, and the other end of the buffer spring 333 is fixed on the outer side of the fixing frame 31.

[0032] Specifically, the inner diameter of the support column 331 should be at least larger than the inner diameter of the buffer spring 333, and the inner diameter of the sleeve column 332 should be at least smaller than the inner diameter of the buffer spring 333. The other end of the buffer spring 333 is fixed to one end where the support column 331 and the sleeve column 332 are connected.

[0033] In this embodiment, the buffer structure 33 uses a support column 331 to provide stability, and then uses a sleeve column 332 to fix the buffer spring 2 333 on its outside. The other end is fixed to the outside of the fixing frame 31, and the buffer structure 33 is ensured to remain vertical on the installation plane of the two, so that its vibration frequency can be transmitted to a greater extent, thereby reducing the impact of vibration.

[0034] Reference Figure 4 The fixed base 4 is also provided with a panel 43 outside the buffer plate 41 , and an L-shaped baffle 44 is also installed on one side of the fixed base 4 , and the L-shaped baffle 44 and the buffer plate 41 are combined into a semi-enclosed space.

[0035] Specifically, the height of the enclosure plate 43 should be at least greater than the height of the buffer plate 41 and less than the height of the lowest point of the fixing frame 31 .

[0036] Specifically, fixing bolts 36 are provided at both ends of the support pad 34 , screw holes 45 corresponding to the fixing bolts 36 are provided on the buffer plate 41 , and a plurality of buffer springs 42 are evenly arranged at the bottom of the buffer plate 41 .

[0037] In this embodiment, the compressor 2 is installed as a whole on the fixed base 4, and an L-shaped baffle 44 is arranged on one side of the fixed base 4. This arrangement can not only isolate the components in the oxygen generator body 1 to avoid mutual influence, but also place some valves and pipelines above the L-shaped baffle 44 to facilitate the internal operation of the oxygen generator body 1. The compressor 2 is placed on the buffer plate 41, which can actually play a certain synergistic role when the supporting shock-absorbing frame 3 cannot achieve the ideal shock-absorbing effect. The buffer spring 42 installed at the bottom of the buffer plate 41 is used to absorb excess vibration, and the buffer spring 42 is relatively short, which can effectively prevent the compressor 2 from shaking during operation. The enclosure 43 arranged on the side of the buffer plate 41 can also protect the compressor 2 to a certain extent.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
