[0067] Figures 1 to 8 The utility model provides a compressor installation structure, which includes a bracket 1, a shock absorbing assembly 2, a connecting assembly 3 and a fixing base 4. The bracket 1 is used to connect the compressor, the shock absorbing assembly 2 is installed between the bracket 1 and the fixing base 4, and the connecting assembly 3 is used to connect the shock absorbing assembly 2 to the fixing base 4.

[0068] like Figure 1 、 Figure 2 and Figure 3 As shown, the shock-absorbing assembly 2 includes a first spring seat 21, a second spring seat 22, and a shock-absorbing spring 23. The first and second spring seats 21 and 22 are connected to opposite ends of the shock-absorbing spring 23. The connecting assembly 3 includes a rubber bolt 31, a stud 32, and a nut 33. The rubber bolt 31 includes a head and a threaded rod. The head is a rubber block that provides a cushioning and shock-absorbing effect. The fixing base 4 includes a fixing plate 41 and a sound-absorbing baffle 42.

[0069] Bracket 1 is connected to first spring seat 21, while second spring seat 22 is connected to fixing seat 4 via connecting assembly 3. One end of stud 32 is connected to second spring seat 22, and the other end is connected to the head of rubber bolt 31. The rod of rubber bolt 31 mates with nut 33 to securely connect to fixing seat 4. Second spring seat 22 presses sound-absorbing baffle 42 against the top surface of fixing plate 41. The rod of rubber bolt 31 passes through fixing plate 41 and is connected to nut 33, which mates with the bottom surface of fixing plate 41.

[0070] The shock-absorbing spring 23 can buffer and reduce the vibration of the compressor connected to the bracket 1, thereby reducing the noise generated by vibration when the compressor is working. The rubber bolt 31 can not only play the role of fixing the connection, but also further play the role of buffering vibration, thereby effectively reducing the noise generated by vibration.

[0071] The compressor is located within the oxygen concentrator. The sound-absorbing baffle 42 absorbs sound energy, further reducing noise transmission from the oxygen concentrator through the mounting base 4, thereby providing a quiet oxygen-using environment for the user. The sound-absorbing baffle 42 can be a porous sound-absorbing baffle, such as inorganic fiber, organic fiber, inorganic foam, foam plastic, or other existing sound-absorbing baffles.

[0072] When the shock-absorbing assembly 2 is installed through the connecting assembly 3, the second spring seat 22 presses the sound-absorbing baffle 42 against the top surface of the fixing plate 41, thereby fixing the sound-absorbing baffle 42, simplifying the installation structure and assembly steps, and helping to reduce costs.

[0073] In some embodiments, multiple groups of shock absorbing components 2 are connected to the bracket 1, and the multiple groups of shock absorbing components 2 are respectively fixedly connected to the fixing base 4 through the connecting components 3. The structure of the bracket 1 can be set according to the shape of the compressor, installation space or other needs.

[0074] In a specific embodiment, the bracket 1 includes a base plate 11 and a vertical plate 12 of an integrated structure. The base plate 11 and the vertical plate 12 form an "L"-shaped structure. The base plate 11 is fixedly connected to the first spring seat 21 by fasteners, and the vertical plate 12 is used to connect to the compressor.

[0075] like Figure 1 In the embodiment shown, two opposite sides of the compressor are respectively connected to a bracket 1, and two opposite ends of each bracket 1 are respectively connected to a shock absorbing assembly 2. Four groups of shock absorbing assemblies 2 support the compressor on a fixing base 4.

[0076] In some embodiments, as Figure 4 As shown, the head of the rubber bolt 31 abuts against and supports the bottom of the second spring seat 22 . The head of the rubber bolt 31 can absorb the vibration energy of the second spring seat 22 and reduce the vibration transmitted to the fixing seat 4 .

[0077] The head of the rubber bolt 31 and the bottom of the second spring seat 22 are respectively provided with threaded holes for connecting the stud 32. The head of the rubber bolt 31 and the second spring seat 22 are respectively threadedly connected to the opposite ends of the stud 32.

[0078] The compressor is supported on the fixing seat 4 through the bracket 1 and the shock-absorbing assembly 2. The load-bearing capacity of the connecting assembly 3 is large, the stud 32 has a strong load-bearing capacity, the connection is stable and reliable, and it is easy to assemble and disassemble. After installation, it is hidden between the rubber bolt 31 and the second spring seat 22. The structure is compact and not easy to loosen.

[0079] In some embodiments, as Figure 3 As shown, the fixing plate 41 is provided with a mounting hole 411, and the sound-absorbing baffle 42 is provided with a mounting clearance hole 4211 corresponding to the mounting hole 411. The bottom of the second spring seat 22 is larger than the mounting clearance hole 4211, while the head of the rubber bolt 31 is smaller than the mounting clearance hole 4211 and abuts against the fixing plate 41. The rod of the rubber bolt 31 passes through the mounting hole 411 and the mounting clearance hole 4211, and the nut 33 tightens the rubber bolt 31. When the second spring seat 22 is connected to the rubber bolt 31 via the stud 32, it can press against the sound-absorbing baffle 42.

[0080] In some embodiments, as Figure 4 and Figure 5 As shown, the mounting hole 411 is constructed as a stepped hole, and the head of the rubber bolt 31 cooperates with the stepped hole. Specifically, a stepped surface 412 is formed in the mounting hole 411, and the head of the rubber bolt 31 abuts against the stepped surface 412.

[0081] In some embodiments, as Figure 4 and Figure 5 As shown, the edge of the mounting hole 411 is provided with a flange 413 that mates with the mounting clearance hole 4211. Specifically, flange 413 is formed at the edge of the mounting hole 411 on the top surface of the fixing plate 41. Flange 413 surrounds the edge of the mounting hole 411, increasing the depth of the mounting hole 411. The head of the rubber bolt 31 fits within flange 413. Flange 413 can be snapped into the mounting clearance hole 4211 to position the mounting clearance hole 4211, thereby ensuring that the second spring seat 22 can press against the sound-absorbing baffle 42.

[0082] In some embodiments, as Figure 4 and Figure 6 As shown, a positioning groove 414 is formed on the bottom surface of the fixing plate 41, surrounding the mounting hole 411. The positioning groove 414 is used to mount the nut 33 and is configured to restrict the rotation of the nut 33. Specifically, the mounting hole 411 extends downward from the edge of the bottom surface of the fixing plate 41 to form the positioning groove 414. The inner side of the positioning groove 414 is configured as a non-circular surface to restrict the rotation of the nut 33. For example, if the nut 33 is a hexagonal nut, the positioning groove 414 is configured as a hexagonal groove. During installation, the nut 33 is installed in the positioning groove 414, and then the rubber bolt 31 is installed in the mounting hole 411. Rotating the rubber bolt 31 threadably connects it to the nut 33.

[0083] In some embodiments, as Figure 4 and Figure 7 As shown, the bottom of the fixing base 4 is connected to the base 5, forming a silencer chamber 6 between the fixing base 4 and the base 5. A mounting hole 411 allows access to the silencer chamber 6. An air inlet 415 is formed on the fixing base 4, communicating with the silencer chamber 6. An air outlet 52 is formed on the base 5, communicating with the silencer chamber 6. Airflow from within the oxygen generator can be discharged after being reduced in noise through the silencer chamber 6.

[0084] Specifically, an air duct for dissipating heat from the compressor is formed in the oxygen production equipment. After passing through the compressor, the air flow in the air duct can enter the silencer chamber 6 through the air inlet 415 and be discharged through the air outlet 52 after being silenced and noise reduced.

[0085] In some embodiments, as Figure 7 and Figure 8 As shown, a sunken groove 51 is formed on the base 5, and an air outlet 52 is provided at one end of the groove 51. An exhaust cover 7 is provided in the groove 51, one end of the exhaust cover 7 extends to the air outlet 52, and the other end forms a hollow hole 71.

[0086] Specifically, a first silencing chamber is formed between the outer side of the exhaust hood 7 and the fixed plate 41, and a second silencing chamber is formed between the inner side of the exhaust hood 7 and the inner wall of the groove 51. The fixed plate 41 is provided with at least one air inlet 415. Airflow enters the first silencing chamber through the air inlet 415, then enters the second silencing chamber through the hollow holes 71 of the exhaust hood 7, and finally is discharged through the air outlet 52. The exhaust hood 7 extends the path of the airflow within the silencing chamber 6, which helps to fully reduce the noise of the airflow. The hollow holes 71 change the flow direction of the airflow, consume the energy of the sound, and also reduce the noise of the airflow.

[0087] In some embodiments, the air inlet 415 can be a plurality of small holes (not shown in the figure) distributed in an array on the fixing plate 41, or can be a single through hole. Figure 8 As shown, the sound-absorbing baffle 42 is provided with an airflow avoidance hole 4212 corresponding to the air inlet 415 , and the airflow can enter the air inlet 415 through the airflow avoidance hole 4212 .

[0088] In some embodiments, as Figure 4 and Figure 8 As shown, the sound-absorbing partition 42 includes a first sound-absorbing cotton 421 arranged on the top surface of the fixing plate 41.

[0089] A second sound-absorbing cotton 422 is provided on the bottom surface of the fixing plate 41 . The second sound-absorbing cotton 422 is located in the silencer cavity 6 and can reduce the noise of the airflow in the silencer cavity 6 .

[0090] Furthermore, the silencer chamber 6 is provided with a third sound-absorbing cotton 423, a fourth sound-absorbing cotton 61, and a fifth sound-absorbing cotton 62. The third sound-absorbing cotton 423 and the fourth sound-absorbing cotton 61 are located in the first silencer chamber, the third sound-absorbing cotton 423 is located on the inner sidewall of the fixing plate 41, and the fourth sound-absorbing cotton 61 is located on the top of the exhaust hood 7.
