DETAILED DESCRIPTION
[0028] The utility model will be further explained in detail below in combination with the drawings and embodiments. Figures 1-9 It should be understood that the specific embodiments described herein are merely intended to explain the utility model and not to limit the utility model.
[0029] Figures 1-9 The compressor multilayer sound insulation device shown in the figure comprises a shell 1 for protecting the compressor, the shell 1 is connected with a chassis 3 for fixing the compressor, the shell 1 is internally provided with a sound insulation structure 2 for sound absorption and sound insulation, and the shell 1, the sound insulation structure 2 and the chassis 3 form a closed sound insulation space 4.
[0030] In the embodiment, the shell and the sound insulation structure provided in the shell are stationary relative to the compressor, they do not directly contact the compressor and do not vibrate together with the compressor. The shell, the sound insulation structure and the chassis jointly form a closed sound insulation space, through the sound insulation structure, different frequency noises can be absorbed and isolated, thereby significantly improving the overall sound insulation effect, and the shell can effectively limit the movement of the compressor during transportation, thereby preventing the compressor from being impacted and damaged.
[0031] Further, the sound insulation structure 2 comprises a sound absorption layer 21 connected with the shell 1 and a shock absorption sound insulation layer 22 connected with the sound absorption layer 21.
[0032] In the embodiment, the sound insulation structure adopts the multilayer combination of the sound absorption layer and the shock absorption sound insulation layer, when the compressor generates noise, the shock absorption sound insulation layer can isolate low-frequency noise first, and then the sound absorption layer can effectively absorb high-frequency noise, and the multilayer structure design makes the sound insulation structure be able to absorb and isolate different frequency noises, thereby improving the overall sound insulation effect of the sound insulation device.
[0033] Further, the sound absorption layer 21 is a fiber felt layer.
[0034] In the embodiment, the fiber felt layer has high sound absorption capacity due to its porous structure, and is light in weight and durable. As a sound absorption layer, it can efficiently absorb high-frequency noise generated by the compressor, broaden the sound absorption frequency band of the sound insulation device, and thus reduce the reflection and propagation of noise.
[0035] Further, the shock-absorbing and sound-insulating layer 22 is a rubber skin layer.
[0036] In the embodiment, the rubber layer has excellent shock-absorbing and sound-insulating effects due to its good elasticity and sound insulation performance. It can effectively absorb and buffer the vibration generated during the operation of the compressor, and effectively isolate the low-frequency noise generated by the compressor. Through the joint action of the rubber layer and the sound absorption layer, the high and low frequency noise can be comprehensively absorbed and isolated.
[0037] Further, the thickness of the rubber skin layer is 1.0 mm.

[0040] In the embodiment, the combination of the first shell and the second shell can more comprehensively wrap the compressor and part of the pipeline.

[0043] Further, the second shell 12 includes a first part 121 and a second part 122 for installation and disassembly.
[0044] In the embodiment, the second shell is designed as a first part and a second part by adopting a split design, so that the installation and disassembly of the second shell are more convenient. When the compressor needs to be maintained or repaired, the second shell can be easily removed without the need to disassemble the entire sound insulation device, thereby improving the maintenance efficiency.
[0045] Further, the first part 121 and the second part 122 are respectively provided with a second fixing groove 124 for mounting and dismounting.
[0046] Specifically, the second fixing groove 124 is provided with a plurality of second connecting holes 127 for mounting and dismounting, and the first part 121 and the second part 122 are provided with a plurality of second mounting holes 125 matched with the second connecting holes 127 on the side away from the second fixing groove 124.
[0047] Further, the first part 121 and the second part 122 are respectively provided with a second connecting lug 126 for connecting with the base 3.
[0048] When the embodiment is used, the noise level of the compressor can be reduced by more than 5dB(A), the noise reduction effect not only meets the requirements of national standards, but also provides a more comfortable and quiet use environment, which is conducive to improving the user experience and reducing the health risk of users.
