Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1, reference Figure 1 to Figure 5 , which is the first embodiment of the utility model, and this embodiment provides a sound-absorbing structure, a sound-absorbing cotton 200, two sound-absorbing cottons 200 are provided, and an accommodation space N is provided between the two sound-absorbing cottons 200, and the sound-absorbing cotton 200 is used to absorb the noise generated by the compressor;

[0033] An adjustment component 300, connected to the sound-absorbing cotton 200, and used to adjust the rotation angle of the sound-absorbing cotton 200;

[0034] The adjustment assembly 300 includes a rotating column 1 301 , a rotating column 2 302 and a transmission member 303 . One end of the rotating column 1 301 penetrates through the rotating column 2 302 , and the other end is connected to the transmission member 303 .

[0035] The invention comprises a box body 100 and a compressor arranged on the box body 100, and further comprises

[0036] The connecting pipe A is arranged at the output part of the compressor. When the compressor is working, the compressor compresses the gas in the box 100 into gas and liquid and discharges it. The connecting pipe A is used to transport the gas and liquid generated by the compressor.

[0037] The sound-absorbing cotton 200 is provided with two pieces, which are rotatably arranged on the connecting pipe A respectively, and the sound-absorbing cotton 200 is used to absorb the noise generated by the compressor;

[0038] The adjusting component 300 is arranged on the connecting pipe A and connected to the sound-absorbing cotton 200. The adjusting component 300 is used to adjust the rotation angle of the sound-absorbing cotton 200.

[0039] Furthermore, at least two rotating posts 302 are provided, and the two rotating posts 302 are respectively fixed on two sound-absorbing cottons 200. When the rotating posts 1 301 and 302 rotate, the sound-absorbing cottons 200 rotate synchronously.

[0040] The adjustment assembly 300 includes a rotating column 1 301 and a rotating column 2 302 respectively arranged on the sound-absorbing cotton 200. When the rotating column 1 301 and the rotating column 2 302 rotate, the sound-absorbing cotton 200 rotates synchronously.

[0041] Furthermore, the rotating column 1 301 can rotate relative to the rotating column 2 302 .

[0042] Transmission components 303 are provided on the rotating column 1 301 and the rotating column 2 302 , and the gas and liquid generated by the compressor are converted into driving force through the transmission components 303 .

[0043] Furthermore, the transmission member 303 includes a transmission block 303a arranged on the outside of the connecting pipe A, and telescopic rods 303b are arranged on the rotating column 1 301 and the rotating column 2 302. The two telescopic rods 303b are rotatably arranged with rotating shafts 303c, and the two rotating shafts 303c are rotatably arranged on the transmission block 303a. When the transmission block 303a slides, the transmission block 303a drives the rotating shaft 303c to rotate, the telescopic rod 303b is stretched, and the telescopic rod 303b rotates synchronously with the rotating column 1 301 and the rotating column 2 302, and then the two silencer cottons 200 connected to the rotating column 1 301 and the rotating column 2 302 rotate and expand. When the power of the compressor is higher, the speed at which the gas and liquid are produced is faster, and then the angle of rotation and expansion of the silencer cotton 200 is larger.

[0044] Furthermore, a gas permeable membrane 400 is provided on the connecting pipe A, and the gas permeable membrane 400 isolates the liquid to prevent the liquid from contacting the silencer cotton 200, so that the silencer cotton 200 is damp and affects the normal operation of the silencer cotton 200.

[0045] Usage process: when the transmission block 303a slides, the transmission block 303a drives the rotating shaft 303c to rotate, and the telescopic rod 303b rotates along the rotating column 1 301 and the rotating column 2 302 while being stretched by the rotating shaft 303c, and the telescopic rod 303b rotates in the opposite direction to the rotating column 1 301 and the rotating column 2 302, and the two silencer cottons 200 connected to the rotating column 1 301 and the rotating column 2 302 rotate and expand. When the power of the compressor is higher, the speed at which the gas and liquid are produced is faster, and the angle of the silencer cotton 200 to rotate and expand is larger. When the compressor is not working, the transmission block 303a is reset, and the silencer cotton 200 rotates and closes, reducing the contact area between the silencer cotton 200 and the outside air, thereby improving the use efficiency of the silencer cotton 200.

[0046] Example 2, reference Figure 1 to Figure 5 , which is the second embodiment of the utility model, is different from the previous embodiment in that a driving member 401 is provided on the connecting pipe A, and the driving member 401 drives the transmission block 303a to slide.

[0047] Furthermore, the driving member 401 includes a branch pipe 401a fixedly passing through the connecting pipe A, a piston 401b is slidably arranged on the branch pipe 401a, a driving column 401c is arranged on the piston 401b, the driving column 401c is slidably arranged on the branch pipe 401a, and the driving column 401c is connected to the transmission block 303a. When the compressor is working, the liquid and gas discharged by the compressor will squeeze the piston 401b, so that the piston 401b slides along the branch pipe 401a, and the piston 401b drives the driving column 401c to slide, and the driving column 401c slides synchronously with the transmission block 303a, so that the silencer cotton 200 rotates and unfolds.

[0048] Furthermore, a spring 402 is provided on the outside of the driving column 401c, and both ends of the spring 402 are respectively connected to the piston 401b and the branch pipe 401a. When the compressor is not working, the elasticity of the spring 402 drives the driving column 401c to reset, and then the transmission block 303a is reset synchronously.

[0049] Usage process: When the compressor is working, the liquid and gas discharged by the compressor will squeeze the piston 401b, causing the piston 401b to slide along the branch pipe 401a, and the piston 401b drives the driving column 401c to slide, and the driving column 401c slides synchronously with the transmission block 303a, and then the silencer cotton 200 rotates and expands; when the compressor is not working, the elasticity of the spring 402 drives the driving column 401c to reset, and then the transmission block 303a is reset synchronously, and the silencer cotton 200 rotates and closes.

[0050] Example 3, reference Figure 1 to Figure 5 , which is the third embodiment of the utility model. Different from the previous embodiment, a heat sink 403 is provided on the connecting pipe A, and the heat sink 403 is used to dissipate heat from the silencer cotton 200.

[0051] Furthermore, a water cooling pipe 403a is passed through the pipe on the connecting pipe A, and the water cooling pipe 403a is fixedly passed through the silencer cotton 200. A one-way valve 403b is arranged on the water cooling pipe 403a, and the one-way valve 403b is used to prevent the liquid from flowing back. When the compressor is working, the liquid discharged by the compressor enters the water cooling pipe 403a from the one-way valve 403b, and the water cooling pipe 403a is transported from the outside of the connecting pipe A to the silencer cotton 200, and finally discharged from the tail of the water cooling pipe 403a, so as to water-cool the silencer cotton 200 to prevent the overheated gas from causing thermal expansion of the silencer cotton 200 material or destroying the fiber structure, thereby weakening the sound absorption and isolation effect of the silencer cotton 200 and reducing the silencer effect.

[0052] Usage process: The rotation and expansion angle of the silencer cotton 200 is changed by the power of the compressor. The greater the power of the compressor, the greater the rotation and expansion angle of the silencer cotton 200, and vice versa. The silencer cotton 200 is water-cooled by the liquid generated by the compressor to prevent overheated gas from causing thermal expansion of the silencer cotton 200 material or destroying the fiber structure, thereby weakening the sound absorption and isolation effect of the silencer cotton 200 and reducing the sound silencing effect.

[0053] Example 4, reference Figure 6 , which is the fourth embodiment of the utility model, provides a box body 100 on the adjustment component 300, a box door 101 arranged on the box body 100, and an observation window 102 arranged on one side of the bottom of the box body 100.

[0054] Usage process: The adjusting component 300 is protected by the box body 100. When the adjusting component 300 fails, the box door 101 can be opened to check the adjusting component 300, and the internal situation of the observation window 102 can be observed in real time through the observation window 102.
