[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] like Figure 1-2The compression structure A should be regarded as the core part of the compressor, that is, the functional component that compresses the gas. The technical solution aims to provide a packaging design for the compression structure A that can reduce operating noise. It is a shell used to encapsulate the compression structure A.

[0021] Embodiment 1: See also Figure 1-3 and Figure 5 The present invention provides the following technical solution: a silent compressor, a compression structure A and a packaging shell 1 for accommodating the compression structure A, and a gap between the inner wall of the packaging shell 1 and the compression structure A is provided with a plurality of sound-absorbing materials 2.

[0022] As an optional embodiment of the present invention, when the compression structure A is in operation, certain noise will be generated, and the noise will be transmitted to the space inside the packaging shell 1 through the compression structure A itself. When the noise reaches the sound-absorbing material 2 in the gap between the packaging shell 1 and the compression structure A, the sound-absorbing material 2 can reduce the noise, and the packaging shell 1 itself is to completely seal the compression structure A, so the packaging shell 1 itself can also play the effect of isolating the noise transmission.

[0023] For the sound-absorbing material 2, since the sound-absorbing technology is already a common existing technology in many fields, such as flexible or porous elastic materials such as sound-absorbing cotton, the present technical solution does not make any specific limitation. For the position distribution of the sound-absorbing material 2, it can be in contact with the inner wall surface of the packaging shell 1, or it can be close to the outer surface of the compression structure A, or it can fill all the gaps between the compression structure A and the packaging shell 1. The present technical solution does not make any specific limitation on the specific shape and position distribution of the sound-absorbing material 2.

[0024] Through the above structure, the core part of the compressor is completely enclosed and installed in the packaging shell 1, forming a modular compressor, and when the compressor is running, the noise generated can be absorbed by the sound-absorbing material 2 in all directions in the gap between the packaging shell 1 and the compression structure, and is isolated by the packaging shell 1, thereby achieving the effect of silent operation of the compressor and avoiding noise pollution.

[0025] like Figure 2 As shown, the packaging shell 1 includes an upper cover 11 and a lower cover 12, and the upper cover 11 and the lower cover 12 are detachably connected.

[0026] As an optional embodiment of the present invention, the packaging shell 1 is designed to be split, which is convenient for assembling the sound absorbing material 2 and the compression structure A.

[0027] Specifically, the sound absorbing material 2 includes a porous elastic material that is clamped in the gap between the inner wall of the packaging shell and the compression structure.

[0028] As an optional embodiment of the present invention, porous elastic materials are commonly used for noise reduction, such as the aforementioned sound-absorbing cotton, which has a good noise-absorbing effect in the packaging shell 1.

[0029] like Figure 3-6 As shown, the sound absorbing material 2 is clamped in the gap between the inner wall of the packaging shell 1 and the compression structure, which facilitates the replacement and installation of the sound absorbing material 2 and will not separate from the packaging shell 1 or the compression structure A when the compressor is running.

[0030] Specifically, the sound absorbing material includes a high-elastic soft gel-like sound absorbing and shock-absorbing material that is cast and filled in the gap between the inner wall of the packaging shell and the compression structure.

[0031] As an optional embodiment of the present invention, the highly elastic soft gel-like sound-absorbing and shock-absorbing material can be understood as a glassy or gel-like substance, which is filled and cast into the gap between the compression structure A and the packaging shell 1, similar to a "jelly" or "gelatin" substance, and it can also achieve a good sound-absorbing effect.

[0032] In the above scheme, the sound-absorbing material 2 can be located in the gap space between the side wall of the packaging shell 1 and the compression structure A, or in the gap space between the bottom wall, top surface of the packaging shell 1 and the compression structure A, or can be installed on the inner wall of the packaging shell 1 or the surface of the compression structure A, and this technical scheme does not limit this.

[0033] Specifically, the sound absorbing material 2 includes an inner lining 21 for fitting the side wall of the packaging shell 1 and a surface lining 22 for fitting the bottom wall and the top surface of the packaging shell 1, which can fully cover the entire inner surface of the packaging shell 1, thereby having a better noise reduction effect.

[0034] like Figure 3-6 As shown, it also includes a mounting structure 13 for fixing the sound absorbing material 2 between the inner wall of the packaging shell 1 and the compression structure A.

[0035] Specifically, a card slot 14 is provided on the side wall of the packaging shell 1 and along the height direction of the side wall. The mounting structure 13 includes an L-shaped card pin 131. One end of the L-shaped card pin 131 is detachably installed in the card slot 14. The mounting structure 13 includes a card strip 132 for clamping the surface lining 22. The card strip 132 is detachably installed on the bottom wall and / or top surface of the packaging shell 1.

[0036] As an optional implementation scheme of the present invention, the inner lining 21 is limited by the L-shaped clamping pin 131, and the surface lining 22 is limited by the clamping strip 132, so that the installation of the entire sound absorbing material 2 in the packaging shell 1 is more convenient.

[0037] like Figure 2 As shown, the packaging shell 1 is filled with sound absorbing liquid.

[0038] As an optional implementation scheme of the present invention, it should be understood that the sound-absorbing liquid refers to a liquid. Theoretically, the liquid also has a certain reduction effect on the transmission of noise and can achieve a noise reduction effect. Therefore, the sound-absorbing liquid in the present technical solution can be any liquid, and the present technical solution is not limited to this.

[0039] Preferably, the sound-absorbing liquid is cooling liquid.

[0040] Preferably, the packaging shell 1 is provided with a pipe joint 3, which can be used for connecting an external liquid supply system, continuously supplying sound-absorbing liquid to the packaging shell 1, and can cool the refluxed sound-absorbing liquid and maintain the noise reduction effect of the internal sound-absorbing liquid. In specific settings, the installation of the pipe joint 3 can be arranged in a bottom-in-top-out manner, and the connection between the upper cover 11 and the lower cover 12 should also be sealed.

[0041] As for the pipe joint 3, in fact, multiple ones can be provided, each providing different functions, such as configuring a tube for manually extracting the internal liquid and a corresponding plug for convenient use during maintenance and cleaning.

[0042] See also Figure 1-2 The compressor also includes a machine foot 4 arranged on the outer wall of the packaging shell 1.

[0043] As an optional embodiment of the present invention, the machine foot 4 facilitates the installation of the compressor.

[0044] The working principle and use process of the present invention are as follows: When the compression structure A is running, a certain amount of noise will be generated, and the noise will be transmitted to the space inside the packaging shell 1 through the compression structure A itself. When the noise reaches the sound-absorbing material 2 on the inner wall of the packaging shell 1, the sound-absorbing material 2 can reduce the noise, and the packaging shell 1 itself is to completely seal the compression structure A, so the packaging shell 1 itself can also play the effect of isolating the noise transmission.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
