[0052] Figures 1 to 6 The illustration shows a housing assembly of a compressor module provided by this invention, for mounting on a device. The device can be an oxygen concentrator or other equipment requiring a compressor, such as a refrigerator or freezer.

[0053] The housing assembly of the compressor module includes a first housing 21, a second housing 22, and a third housing 23. The first housing 21 includes a top plate 211 and a first surrounding plate 212. The top plate 211 has opposing first and second ends, and the first surrounding plate 212 is connected to the first end of the top plate 211 and extends to opposite sides of the top plate 211. The second housing 22 includes a bottom plate 221 and a second surrounding plate 222. The bottom plate 221 has opposing first and second ends, and the second surrounding plate 222 is connected at least to the second end of the bottom plate 221. The second surrounding plate 222 mates with the first surrounding plate 212. The top plate 211 and the bottom plate 221 are positioned opposite each other, and the second housing 22 and the first housing 21 form an internal cavity for mounting the compressor assembly 24. The third housing 23 mates with the outside of the first housing 21 and the second housing 22.

[0054] At least one first connecting structure 201 is provided between the first housing 21, the second housing 22 and the third housing 23. The first connecting structure 201 includes a first connecting part 2011 respectively provided on the top plate 211, the second enclosure plate 222 and the third housing 23. Each first connecting part 2011 is fixedly connected by a first fastener, thereby fixing the first housing 21, the second housing 22 and the third housing 23 together.

[0055] Reference Figure 2 From the perspective of the image, the first and second ends of the housing assembly are the left and right ends. The first enclosure 212 extends downward from the edge of the top plate 211, the second enclosure 222 extends upward from the edge of the bottom plate 221, and the third housing 23 surrounds part of the sides of the first housing 21 and the second housing 22.

[0056] The first connecting structure 201 can fix the three components—the first housing 21, the second housing 22, and the third housing 23—together using a first fastener. This reduces the number of parts and steps involved in disassembly and assembly, thus lowering the difficulty of disassembly and assembly. Figure 6As shown, the top plate 211 and the first enclosure plate 212 of the first housing 21 form a semi-enclosed structure. After removing the first housing 21, more of the compressor assembly 24 in the inner cavity can be exposed, which is convenient for observing the status of the compressor assembly 24. It is also possible to directly inspect some parts of the compressor assembly 24, reducing the disassembly and assembly work before and after maintenance.

[0057] Specifically, the first connecting portions 2011 of the first connecting structure 201 are close to each other to facilitate the installation of the first fasteners. The second enclosure plate 222 of the second housing 22 extends upward and can approach the top plate 211, thereby allowing the first connecting portions 2011 on the second enclosure plate 222 to approach the first connecting portions 2011 on the top plate 211. The first connecting structure 201 is close to the top of the housing assembly, which facilitates the installation and removal of the first fasteners.

[0058] Furthermore, the bottom end of the first enclosure 212 engages with the first end of the bottom plate 221, and the top end of the second enclosure 222 engages with the second end of the top plate 211, thereby enclosing the compressor assembly 24 in the inner cavity, and allowing the first connecting portion 2011 on the second enclosure 222 to approach the first connecting portion 2011 on the top plate 211.

[0059] In some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the housing assembly also includes at least one second connection structure 202. The second connection structure 202 includes a second connection portion 2021 respectively disposed on the first enclosure plate 212 and the bottom plate 221. The two second connection portions 2021 are fixedly connected by a second fastener.

[0060] The second connecting structure 202 can enhance the connection stability between the first housing 21 and the second housing 22. The first connecting structure 201 and the second connecting structure 202 are distributed at opposite ends of the housing assembly, and the first connecting structure 201 connects the top plate 211 and the second enclosure plate 222, while the second connecting structure 202 connects the bottom plate 221 and the first enclosure plate 212, which enables a more stable connection between the first housing 21 and the second housing 22.

[0061] The disassembly process of the housing assembly is as follows: remove the first fastener on the first connecting structure 201, disassemble the third housing 23, then remove the second fastener on the second connecting structure 202, and separate the first housing 21 and the second housing 22.

[0062] In some embodiments of this utility model, such as Figure 4 and Figure 5As shown, the second connecting portion 2021 on the first enclosure 212 is a through hole and is located at the bottom end of the first enclosure 212; the second connecting portion 2021 on the bottom plate 221 is a threaded hole and is located at the first end of the bottom plate 221. Specifically, the two second connecting portions 2021 are coaxially corresponding, and the second fastener is a screw. The screw passes through the second connecting portion 2021 of the first enclosure 212 and is threadedly connected to the second connecting portion 2021 of the bottom plate 221.

[0063] To facilitate the installation and removal of the second fastener, a structural groove corresponding to the second connecting part 2021 can be provided on the first enclosure 212. The structural groove extends from the second connecting part 2021 to the top of the second enclosure 222 to facilitate the manual installation and removal of the second fastener using tools.

[0064] In some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the first connecting portion 2011 on the third housing 23 is a through hole and is located inside the third housing 23; the first connecting portion 2011 on the top plate 211 is a through hole and is located at the second end of the top plate 211; the first connecting portion 2011 on the second enclosure plate 222 is a threaded hole and is located at the top end of the second enclosure plate 222. Specifically, the three first connecting portions 2011 are coaxially corresponding, and the first fastener is a screw. The screw passes through the first connecting portions 2011 of the third housing 23 and the top plate 211, and is threadedly connected to the first connecting portion 2011 of the second enclosure plate 222.

[0065] The first fastener can be installed horizontally or vertically on the first connecting structure 201, and the second fastener can be installed horizontally or vertically on the second connecting structure 202.

[0066] To facilitate manual assembly and disassembly, both the first and second fasteners are installed vertically. Specifically, the axes of the through hole and threaded hole of the first connecting structure 201 extend vertically, and the first fastener is vertically connected to the first connecting structure 201. The through hole and threaded hole of the second connecting structure 202 extend vertically, and the second fastener is vertically connected to the second connecting structure 202.

[0067] Furthermore, the first housing 21 is located above the second housing 22. During disassembly, the third housing 23 moves upwards away from the first housing 21 and the second housing 22, and the first housing 21 moves upwards away from the second housing 22 during disassembly. The first connecting portion 2011 on the third housing 23, the first connecting portion 2011 on the top plate 211, and the first connecting portion 2011 on the second surrounding plate 222 are sequentially arranged from top to bottom to allow the third housing 23 and the first housing 21 to be disassembled sequentially. The second connecting portion 2021 on the first surrounding plate 212 is located above the second connecting portion 2021 on the bottom plate 221 to allow the first housing 21 to be easily disassembled.

[0068] In some embodiments of this utility model, two first connecting structures 201 are provided and are arranged at intervals at the second end of the housing assembly; one second connecting structure 202 is provided and is located at the first end of the housing assembly.

[0069] like Figure 5 In one specific embodiment shown, two first connecting structures 201 are distributed at two apex corners of the second end of the housing assembly, and a second connecting structure 202 is located at one of the apex corners of the first end of the housing assembly.

[0070] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the first end of the housing assembly is used to mate with the equipment, and the third housing 23 surrounds the second end and opposite sides of the housing assembly. The third housing 23 can protect the first housing 21 and the second housing 22, thereby increasing the protection of the internal compressor assembly 24.

[0071] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the housing assembly is configured to be inserted into the mounting groove 11 of the device along the mounting direction from the second end to the first end. The first end of the housing assembly corresponds to the sidewall of the mounting groove 11. Specifically, the mounting groove 11 forms a C-shaped structure and has a groove top, a groove bottom, and sidewalls. A first enclosure plate 212 is used to correspond to the sidewall of the mounting groove 11, a top plate 211 is used to mate with the groove top of the mounting groove 11, and a bottom plate 221 is used to mate with the groove bottom of the mounting groove 11. A third housing 23 forms a C-shaped structure, and the portions of the first housing 21 and the second housing 22 that do not mate with the mounting groove 11 are surrounded by the third housing 23.

[0072] In some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the third housing 23 is guided and engaged with the first enclosure 212 and the second enclosure 222 along the height direction from the top plate 211 to the bottom plate 221, which can install and position the third housing 23 and restrict the installation and removal direction of the third housing 23.

[0073] In some embodiments of this utility model, such as Figure 4 and Figure 6As shown, the first enclosure 212 extends to opposite sides of the top plate 211, forming a semi-enclosed structure with the first housing 21 and the second housing 22. A positioning structure 204 can be provided between the first housing 21 and the second housing 22. When the first housing 21 and the second housing 22 are fastened together, they can be engaged and positioned relative to each other through the positioning structure 204 to facilitate the installation of the first and second fasteners. Specifically, the positioning structure 204 can be provided between the first enclosure 212 and the second enclosure 222, with the first enclosure 212 and the second enclosure 222 being engaged through the positioning structure. The positioning structure 204 can also be provided on the top plate 211 or the bottom plate 221.

[0074] Furthermore, the positioning structure 204 is configured as an outwardly protruding structure that extends along the height direction. The third housing 23 is guided and engaged with the positioning structure 204 along the height direction. The positioning structure positions the third housing 23 during installation, thus restricting the direction of installation and removal of the third housing 23. The positioning structure 204 achieves both the installation and positioning of the first housing 21 and the second housing 22, as well as the installation and positioning of the third housing 23.

[0075] In some specific implementation methods, such as Figure 4 and Figure 6 As shown, the positioning structure 204 includes a first engaging portion 2041 located at the edge of the first enclosure 212 and a second engaging groove 2042 located at the edge of the second enclosure 222. The first engaging portion 2041 and the second engaging groove 2042 are inserted into each other. Specifically, when the first housing 21 and the second housing 22 are connected, the first engaging portion 2041 and the second engaging groove 2042 are inserted into each other along the height direction, with the first engaging portion 2041 inserted into the second engaging groove 2042. The second engaging groove 2042 extends along the height direction, and a guide strip that guides and cooperates with the side wall of the second engaging groove 2042 can be provided on the inner side of the third housing 23. When the third housing 23 is assembled or disassembled along the height direction, it slides along the side wall of the second engaging groove 2042 via the guide strip.
