[0030] Various specific embodiments of the present invention will be described below with reference to the accompanying drawings that form a part of this specification. It should be understood that although terms indicating directions, such as "front", "rear", "upper", "lower", "left", "right", etc., are used in the present invention to describe various example structural parts and elements of the present invention in a directional or orientational manner, these terms are used here only for the purpose of convenience of description and are determined based on the example orientations shown in the accompanying drawings. Since the embodiments disclosed in the present invention can be arranged in different directions, these directional terms are only for illustration and should not be regarded as limiting. In the following drawings, the same figure numbers are used for the same parts.

[0031] Figure 1 is a three-dimensional diagram of the compressor assembly of the present application. Figure 1 As shown, the compressor assembly includes an outer shell 102 and an inner shell 104. The inner shell 104 is used to accommodate a rotor (not shown), and an inner shell port 112 is provided on the inner shell 104. The inner shell 104 is disposed in the outer shell 102. An outer shell port 114 is provided on the outer shell 102. The gas compressed by the rotor can flow out of the inner shell 104 through the inner shell port 112, and flow out of the compressor assembly through the outer shell port 114.

[0032] Figure 2 yes Figure 1 An exploded view of the compressor assembly is shown. Figure 2 As shown, the housing 102 defines a housing cavity 202. Specifically, the housing 102 includes a circumferential portion 241 and an end cover 242. The circumferential portion 241 is annular and has a compressor axis X. The housing port 114 is disposed on the circumferential portion 241. The circumferential portion 241 and the end cover 242 are connected to form a housing cavity 202 having an opening on one side. The housing 102 is provided with a plurality of recesses 212. The recesses 212 are formed by extending outward from the inner wall of the housing port 114 and are in fluid communication with the housing cavity 202.

[0033] like Figure 2As shown, the inner shell 104 includes an inner shell body 251 and a sealing plate 252. The inner shell body 251 is barrel-shaped, thereby forming an inner shell cavity 204 with an opening on one side. An inner shell port 112 is provided on the circumferential side wall of the inner shell body 251. The inner shell cavity 204 is used to accommodate a rotor (not shown). The sealing plate 252 closes the inner shell cavity 204. Several holes are provided on the sealing plate 252, so that components such as the rotor can enter the inner shell cavity 204 through the holes. When components such as the rotor enter the inner shell cavity 204 through the holes and are installed in place, the several holes on the sealing plate 252 are blocked. Therefore, the gas in the inner shell cavity 204 can only flow out through the inner shell port 112. In addition, several recesses 214 are provided on the inner shell body 251. The recess 214 is formed by being recessed inward from the outer wall of the inner shell body 251. When the inner housing 104 and the outer housing 102 are in place, the recess 214 is in fluid communication with the inner housing cavity 204 .

[0034] It should be noted that although the embodiments of the present application show that several recesses are arranged on the inner wall of the outer shell 102 and the outer wall of the inner shell 104, in other embodiments, at least one recess is arranged on the inner wall of the outer shell 102 and / or the outer wall of the inner shell 104 and are all within the protection scope of the present application.

[0035] Figure 3A yes Figure 1 The compressor assembly is shown along Figure 1 A cross-sectional view of AA is shown. Figure 3A The cross-sectional view shown is a transverse plane passing through the compressor axis X and passing through the inner shell opening 112 and the outer shell opening 114. Figure 3A As shown, when the inner shell 104 and the outer shell 102 are installed in place, a muffler channel 302 is formed between the inner shell 104 and the outer shell 102. The muffler channel 302 communicates the inner shell port 112 on the inner shell 104 and the outer shell port 114 on the outer shell 102. In the transverse cross-section of the compressor assembly, the inner shell port 112 and the outer shell port 114 are arranged on opposite sides of the inner shell volume 204. In other words, the inner shell port 112 and the outer shell port 114 are arranged on opposite sides of the compressor axis X. This enables the gas flowing out of the inner shell port 112 to flow along the periphery of the inner shell 104 of the compressor assembly. In other words, this enables the gas flowing out of the inner shell port 112 to flow roughly as far as possible along the periphery of the outer shell 102 of the compressor assembly and as long as possible in the compressor assembly. In an embodiment of the present application, the inner shell port 112 and the outer shell port 114 are both roughly circular, and the inner shell port 112 and the outer shell port 114 are coaxially arranged.

[0036] like Figure 3AAs shown, the muffler channel 302 includes a first channel 311 and a second channel 312 extending in the direction of the compressor axis X and a third channel 313 extending in a direction different from the compressor axis X. The third channel 313 is substantially perpendicular to the first channel 311 and the second channel 312, and connects the first channel 311 and the second channel 312. The recess 212 and the recess 214 are both in fluid communication with the muffler channel 302, and are configured to muffle the gas in the muffler channel 302.

[0037] In an embodiment of the present application, the shape of the recess 212 is the same as the shape of the recess 214, so as to silence the gas of the same frequency. In other embodiments, the recess 212 and the recess 214 can be configured to silence the gas of different frequencies. For example, the recess 212 and the recess 214 have different shapes (e.g., width, depth, etc.).

[0038] It should also be noted that, although in the embodiments of the present application, the recess is a rectangular parallelepiped and the cross-sectional area of ​​the recess is roughly a rectangle with the same width, in other embodiments, the cross-sectional area of ​​the recess can be various shapes, for example, the recess is a cylinder and the cross-sectional area of ​​the recess is roughly a rectangle with the same width, or the recess has a thinner neck and a larger body to form a resonant sound absorption.

[0039] In the present application, in the circumferential direction of the compressor assembly, the first channel 311 and the second channel 312 are not connected. That is, the first channel 311 and the second channel 312 are connected only through the third channel 313, and the third channel 313 and the sealing plate 252 are arranged on opposite sides of the inner shell body 251. Figure 2 and Figure 3B To describe the specific structure in the compressor assembly.

[0040] Figure 3B yes Figure 1 The cross-sectional view of the compressor assembly shown in FIG. 1 is perpendicular to the compressor axis X. Figure 3B As shown, when the inner shell 104 and the outer shell 102 are installed in place, the outer shell 102 and the inner shell 104 form a first sealing structure 321 and a second sealing structure 322 that are arranged opposite to each other in the circumferential direction of the compressor assembly, so that the first channel 311 and the second channel 312 are connected only through the third channel 313.

[0041] Back to Figure 2 And as Figure 2As shown, the circumferential portion 241 of the outer shell 102 includes a first outer fitting portion 261 and a second outer fitting portion 262 that are arranged opposite to each other. The first outer fitting portion 261 and the second outer fitting portion 262 are formed by extending a distance along the compressor axis X. More specifically, the first outer fitting portion 261 is arranged at the upper part of the circumferential portion 241 and the second outer fitting portion 262 is arranged at the lower part of the circumferential portion 241, for matching with the inner shell 104. The inner shell body 251 of the inner shell 104 includes a first inner fitting portion 271 and a second inner fitting portion 272 that are arranged opposite to each other. The first inner fitting portion 271 and the second inner fitting portion 272 are formed by extending a distance along the compressor axis X. More specifically, the first inner fitting portion 271 is arranged at the upper part of the inner shell body 251 and the second inner fitting portion 272 is arranged at the lower part of the second inner fitting portion 272, for matching with the circumferential portion 241 of the outer shell 102. When the outer shell 102 and the inner shell 104 are installed in place, the first inner fitting portion 271 fits and abuts the first outer fitting portion 261 and the second inner fitting portion 272 fits and abuts the second outer fitting portion 262, so that in the circumferential direction of the compressor assembly, the first channel 311 and the second channel 312 are not connected. In the embodiment of the present application, the first outer fitting portion 261, the second outer fitting portion 262, the first inner fitting portion 271 and the second inner fitting portion 272 are all planes, but it can be understood that in other embodiments, the first outer fitting portion 261 and the second outer fitting portion 262 have matching shapes, and the first inner fitting portion 271 and the second inner fitting portion 272 have matching shapes.

[0042] like Figure 3B As shown, when the inner shell 104 and the outer shell 102 are installed in place, the first inner fitting portion 271 fits and abuts the first outer fitting portion 261 to form a first sealing structure 321, and the second inner fitting portion 272 fits and abuts the second outer fitting portion 262 to form a second sealing structure 322, thereby forming sealing structures above and below to prevent the first channel 311 and the second channel 312 from being connected in the circumferential direction of the compressor assembly.

[0043] In addition, if Figure 2 As shown, the compressor assembly further includes a sound-absorbing material 232. The sound-absorbing material 232 is disposed in the recess 212 and / or the recess 214, so as to absorb the gas in the sound-absorbing passage 302. The sound-absorbing material 232 includes foam plastic, foam metal, fiber cotton (such as polyester fiber cotton, glass fiber cotton), a resonance sound-absorbing board, etc.

[0044] The compressor assembly of the present application has the advantages of good silencing effect, compact structure, small volume and simple structure. Specifically, in the present application, the silencing channel is formed by the space between the outer shell and the inner shell, so that the overall volume of the compressor assembly is small. The silencing channel includes a first channel and a second channel along the axis of the compressor, and a third channel perpendicular to the first channel and the second channel. The space between the outer shell and the inner shell is used to construct a silencing channel as long as possible, thereby achieving a better silencing effect.

[0045] Figure 4-Figure 6 are exploded views of three other embodiments of the compressor assembly of the present application. Figure 4-Figure 6 The compressor components and Figure 1-Figure 3B The similarities of the compressor components in the embodiment will not be described in detail, and the main differences are: three structures of the inner shell 104 and the outer shell 102 and their installation methods.

[0046] Figure 4 1 is an exploded view of the first embodiment of the inner shell 104 and the outer shell 102 of the present application. Figure 4 As shown, the outer shell 102 includes a phase-separated end cap 242 and a circumferential portion 241. The end cap 242 is provided with a plurality of recesses 212. The left and right walls of the circumferential portion 241 are respectively provided with a plurality of recesses 212. The left and right walls of the inner shell body 251 of the inner shell 104 are respectively provided with a plurality of recesses 214. The first outer fitting portion 261 and the first inner fitting portion 271 are both planes. The second outer fitting portion 262 and the second inner fitting portion 272 are arc surfaces.

[0047] During the installation process, the operator can choose whether to fill the sound-absorbing material 232 in the recess 212 and / or the recess 214 as needed. Subsequently, the operator can extend the inner shell body 251 into the circumferential portion 241 until the sealing plate 252 contacts and abuts the inner shell body 251. Then, the operator connects the end cover 242 and the circumferential portion 241 (for example, welding), and connects the inner shell body 251 and the circumferential portion 241. Thus, the separated end cover 242 and the circumferential portion 241 can provide a flexible operating space for the operator to set the sound-absorbing material.

[0048] Figure 5 1 is an exploded view of the second embodiment of the inner shell 104 and the outer shell 102 of the present application. Figure 5 As shown, the outer shell 102 includes a first side shell member 512 and a second side shell member 514 that are separated from each other. The first side shell member 512 and the second side shell member 514 are substantially symmetrically arranged. Each of the first side shell member 512 and the second side shell member 514 includes an arc portion 522 and an end portion 524. When the outer shell 102 and the inner shell 104 are connected, the end portion 524 of the first side shell member 512 and the end portion 524 of the second side shell member 514 abut and connect, thereby forming a Figure 2The end cap 242 is shown. The inner walls of the first side housing member 512 and the second side housing member 514 may both be provided with a recess 212 .

[0049] like Figure 5 As shown, the compressor assembly further includes a first protrusion 502 and a second protrusion 504. The first protrusion 502 and the second protrusion 504 are disposed on the inner shell 104. Specifically, the inner shell 104 includes an inner shell body 251 and a sealing plate 252. The specific structures of the inner shell body 251 and the sealing plate 252 can be referred to Figure 1-Figure 3B The relevant description of the embodiment in the embodiment will not be repeated here. The first protrusion 502 and the second protrusion 504 are arranged on opposite sides of the inner shell body 251 and connected to the inner shell body 251. More specifically, the first protrusion 502 and the second protrusion 504 are formed by extending outward from the upper surface and the lower surface of the inner shell body 251. When the inner shell 104 and the outer shell 102 are installed in place, the first side shell member 512 and the second side shell member 514 are arranged on opposite sides of the first protrusion 502, and the first side shell member 512 and the second side shell member 514 are arranged on opposite sides of the second protrusion 504, so that the first side shell member 512 and the second side shell member 514 can clamp the first protrusion 502 and the second protrusion 504 to form the first sealing structure 321 and the second sealing structure 322 respectively.

[0050] Thus, the separated first side shell member 512 and the second side shell member 514 can provide a flexible operating space for the operator to set the sound-absorbing material. In addition, the sealing structure formed by the first protruding member 502 and the second protruding member 504 being clamped by the first side shell member 512 and the second side shell member 514 has a better sealing effect.

[0051] Figure 6 1 is an exploded view of the third embodiment of the inner shell 104 and the outer shell 102 of the present application. Figure 6 The structure of the inner shell 104 and the outer shell 102 shown is similar to Figure 1-Figure 3B The similarities between the structures of the inner shell 104 and the outer shell 102 shown in the figure are not repeated here, and the main difference is that when the inner shell 104 and the outer shell 102 are installed in place, the first channel 311 and the second channel 312 can communicate in the circumferential direction of the compressor assembly. In other words, there is a gap between the upper part of the inner shell 104 and the upper part of the outer shell 102, and there is a gap between the lower part of the inner shell 104 and the lower part of the outer shell 102.

[0052] like Figure 6As shown, the compressor assembly further includes a first partition 612 and a second partition 614. When the compressor assembly is installed in place, the first partition 612 is disposed above the inner shell 104 and is clamped by the inner shell 104 and the outer shell 102, and the second partition 614 is disposed below the inner shell 104 and is clamped by the inner shell 104 and the outer shell 102. In other words, the first partition 612 abuts against the inner shell 104 and the outer shell 102, and the second partition 614 abuts against the inner shell 104 and the outer shell 102. The first partition 612 and the second partition 614 are configured so that the compressor gas flowing out of the inner shell port 112 enters the first channel 311 and then flows into the second channel 312 through the third channel 313, rather than flowing from the first channel 311 into the second channel 312 through the first partition 612 and the second partition 614. In other words, the first separator 612 and the second separator 614 are configured such that: the resistance encountered by the gas flowing from the first channel 311 through the first separator 612 and the second separator 614 into the second channel 312 is much greater than the resistance encountered by the gas flowing from the first channel 311 through the third channel 313 into the second channel 312. As an embodiment, the first separator 612 and the second separator 614 are formed of metal wires. More specifically, the first separator 612 and the second separator 614 are formed of dense metal wires.

[0053] Thus, when the gas compressed by the compressor assembly contains liquid lubricant, the lubricant is easily attached to the first partition 612 and the second partition 614. This can achieve a gas-liquid separation effect, thereby reducing the amount of liquid lubricant carried in the gas flowing out of the housing port 114.

[0054] In addition, if Figure 6 As shown, the inner shell 104 includes an inner shell body 251 and a sealing plate 252. The specific structure of the inner shell body 251 and the sealing plate 252 can be referred to Figure 1-Figure 3B The relevant description of the embodiments in the above will not be repeated here. Figure 6 The difference between the inner shell body 251 shown is that a first accommodating portion 602 and a second accommodating portion (not shown) are provided on the inner shell body 251. The first accommodating portion 602 and the second accommodating portion are arranged roughly symmetrically. Specifically, the first accommodating portion 602 is formed by being recessed downward from the upper surface of the inner shell body 251, and is used to accommodate the first partition 612. The second accommodating portion is formed by being recessed upward from the lower surface of the inner shell body 251, and is used to accommodate the second partition 614. During the installation process, the first partition 612 and the second partition 614 can be respectively arranged in the first accommodating portion 602 and the second accommodating portion, so as to avoid the first partition 612 and the second partition 614 from moving relative to the inner shell 104 when the inner shell 104 extends into the outer shell 102.

[0055] In the embodiments of the present application, Figure 2As shown, the recess 212 and / or the recess 214 can contain the muffler material 232, so as to muffle the gas in the muffler channel 302. In other embodiments, any muffler component can be disposed in the recess 212 and / or the recess 214.

[0056] Figure 7 FIG. 1 is a cross-sectional view of an embodiment of a muffler assembly, thereby illustrating the specific structure of the muffler assembly. Figure 7 As shown, the sound-absorbing component includes a sound-absorbing material 232, a wrapping component 702 and a protective component 704. The sound-absorbing material 232 is roughly a cube. The sound-absorbing material 232 is configured to be able to absorb sound. The wrapping component 702 wraps the sound-absorbing material 232 (that is, the wrapping component 702 wraps the periphery of the sound-absorbing material 232), and is configured to allow sound to enter the sound-absorbing material 232 through the wrapping component 702, and is configured to prevent liquid from entering the sound-absorbing material 232 through the wrapping component 702. The protective component 704 wraps the wrapping component 702 (that is, the protective component 704 wraps the periphery of the wrapping component 702), thereby protecting the wrapping component 702. The protective component 704 is configured to allow sound and liquid to enter the wrapping component 702 through the wrapping component 702. As an example, the wrapping component 702 is made of plastic materials such as polycarbonate, polyethylene, and polyvinyl fluoride. The wrapping component 702 can prevent liquid from entering the sound-absorbing material 232, thereby preventing the liquid from penetrating into the sound-absorbing material and reducing the sound-absorbing performance of the sound-absorbing material 232. As an example, the protective component 704 is made of a fiber material. The fiber material includes natural fibers (such as cotton and linen) and chemical fibers (such as nylon). The protective component 704 is generally in the shape of a film and is used to protect the wrapping component 702.
