[0039] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "up," "down," "left," and "right" generally refer to up, down, left, and right in the actual use or working state of the device, specifically the drawing directions in the accompanying drawings.

[0040] In this application, unless otherwise expressly specified and limited, the terms "connected," "linked," "stacked," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two elements or the interaction between two elements. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0041] In this application, the term "parallel" includes not only absolute parallelism but also approximate parallelism as commonly understood in engineering. For example, "parallel" refers to the angle between two lines, a line and a surface, or a surface, where the angle is between -1° and 1°. Similarly, "perpendicular" also includes not only absolute perpendicularity but also approximate perpendicularity as commonly understood in engineering. For example, "perpendicular" refers to the angle between two lines, a line and a surface, or a surface, where the angle is between 89° and 91°. Equal distances or equal angles include not only absolute equality but also approximate equality as commonly understood in engineering, meaning there may be a certain degree of error, such as a tolerance range of -1% to 1%.

[0042] This application provides a dustproof mesh and a cabinet including the dustproof mesh, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, in the following embodiments, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0043] During the regular maintenance of the dust filter, several screws on the side of the cabinet need to be removed, and the dust filter structure needs to be pulled out of the cabinet. Then, the dust filter component in the dust filter structure needs to be replaced, and finally, the dust filter structure needs to be reassembled into the predetermined position and the screws need to be installed in sequence.

[0044] During disassembly and assembly, sufficient space needs to be reserved for the dust filter structure to be pulled out from the side of the cabinet, which is not conducive to the side-by-side arrangement of multiple cabinets. Furthermore, replacing the dust filter structure requires repeatedly removing and installing multiple screws, reducing the maintenance efficiency of the cabinet.

[0045] To address the technical problems of cumbersome disassembly and assembly procedures in existing dustproof mesh structures, which hinder the replacement and maintenance of dust filter components and prevent the parallel arrangement of multiple cabinets, this application provides a dustproof mesh comprising a frame, at least one partition plate, a limiting member, at least two dust filter components, and a pressure strip plate. At least one partition plate is disposed within the frame to divide the frame into at least two enclosures; the limiting member is disposed on the inner side wall of the enclosure; each dust filter component is disposed within its respective enclosure; the pressure strip plate is detachably disposed on the partition plate. Because the pressure strip plate is detachable, it eliminates the need for excessive screw removal, reducing disassembly and assembly time and minimizing reliance on tools. Therefore, dust filter component replacement or maintenance can be achieved simply by disassembling and assembling the pressure strip plate, improving the efficiency of dust filter component replacement or maintenance. The limiting member and the pressure strip plate are located on opposite sides of the dust filter components, effectively securing them and preventing displacement or detachment during use, thereby improving the stability and reliability of the dustproof mesh. Furthermore, the dust filter can be removed from inside the frame, eliminating the need for sufficient space for replacement or maintenance. This allows for the side-by-side arrangement of multiple racks, improving space utilization in the rack environment. A detailed explanation will follow with reference to the attached diagram.

[0046] like Figure 1-3 As shown, this application embodiment provides a cabinet 100, including a shell 1001 and a dustproof net 1002. The shell 1001 has an installation plate 1003 inside and is located at the bottom of the shell 1001. The dustproof net 1002 is detachably installed on the installation plate 1003.

[0047] like Figure 4 As shown, the dustproof net 1002 includes a frame 1, at least one partition plate 2, a limiting member 3, at least two dustproof filter elements 4, and a pressure strip plate 6.

[0048] At least one partition 2 is set inside the frame 1 to divide the frame 1 into at least two enclosures 10. In this way, multiple partitions 2 can be set inside the frame 1. Users can adjust the number and size of the enclosures 10 according to actual needs, so as to flexibly adapt to different usage scenarios and requirements.

[0049] The limiting component 3 is set on the inner side wall of the frame 10, and each dust filter component 4 is set inside the frame 10.

[0050] In one embodiment, the limiting member 3 and the frame 10 can be integrally formed, which reduces the installation steps of the dustproof net 1002. Furthermore, during assembly, the dustproof filter 4 needs to be tilted before it can be installed into the frame 10. In another embodiment, the limiting member 3 can also be detachably installed on the frame 10 and protrude from the inner wall of the frame 10. Specifically, the frame 10 has mounting holes for the limiting member 3, and the limiting member 3 protrudes from the inner wall of the frame 10. This allows the dustproof filter 4 to be installed into the frame 10 without tilting, improving the installation flexibility of the dustproof filter 4.

[0051] The pressure plate 6 is detachably mounted on the partition plate 2, which makes the installation and replacement of the dust filter 4 more convenient, reduces disassembly and assembly time, and reduces reliance on tools, thereby reducing the difficulty and cost of maintenance.

[0052] The limiting component 3 and the pressure plate 6 are located on opposite sides of the dust filter component 4, which can effectively fix the dust filter component 4 and prevent it from shifting or falling off during use, thereby improving the stability and reliability of the dust filter 1002.

[0053] Therefore, the dust filter 4 can be replaced or maintained simply by disassembling and assembling the pressure strip 6, improving the efficiency of dust filter 4 replacement or maintenance. Furthermore, the dust filter 4 can be removed from inside the frame 10 without requiring sufficient space for replacement or maintenance, allowing multiple cabinets 100 to be arranged side-by-side, thus improving the space utilization of the cabinet 100's on-site environment.

[0054] In this embodiment, the dustproof net 1002 has a first direction Z, a second direction X, and a third direction Y that intersect each other in pairs, wherein the first direction Z is the height direction of the partition plate 2, the second direction X is the length direction of the partition plate 2, and the third direction Y is the width direction of the partition plate 2.

[0055] It is understandable that the first direction Z, the second direction X, and the third direction Y intersect each other and are perpendicular to each other.

[0056] The dust filter element 4 has a flange 40 on the side near the partition plate 2, and the flange 40 is disposed on the partition plate 2 in the first direction Z. By providing the flange 40 on the dust filter element 4 and connecting it to the partition plate 2 in the first direction Z, the fixation of the dust filter element 4 is increased, preventing it from shifting during use.

[0057] like Figure 4As shown, the dust filter 1002 also includes a guide 5, which is connected to the flanged portion 40 in the first direction Z and extends towards the pressure strip 6. The pressure strip 6 is detachably mounted on the flanged portion 40 via the guide 5, allowing the pressure strip 6 to be easily installed and removed via the guide 5. This design allows users to quickly replace or adjust the dust filter 4 as needed to adapt to different usage environments and requirements.

[0058] The combination of the flanged portion 40 and the partition plate 2, along with the use of the guide member 5, effectively improves the sealing between the dust filter element 4 and the frame 1, reducing the possibility of dust seeping through gaps. The design of the guide member 5 not only helps to fix the pressure strip plate 6, but also enhances the stability of the entire dustproof net 1002 structure to a certain extent, ensuring that it maintains a good shape and function during use.

[0059] The flanges 40 of two adjacent dust filter elements 4 are set close to each other, so that the two dust filter elements 4 can be fixed by a pressure strip 6, and the dust filter elements 4 can be replaced and maintained by simply removing and installing the pressure strip 6.

[0060] like Figure 4-7 As shown, the dust filter element 4 includes a first filter plate 41, a second filter plate 42, and filter cotton 43. The first filter plate 41 and the second filter plate 42 are spaced apart in the first direction Z, and the filter cotton 43 is disposed between the first filter plate 41 and the second filter plate 42 in the first direction Z. Therefore, the first filter plate 41 and the second filter plate 42 can fix the multiple layers of filter cotton 43, ensuring that the filter cotton 43 remains in the proper position during use and is not easily deformed or displaced. The mesh size of each layer of filter cotton 43 can be different, which can effectively capture dust particles of different sizes and improve the overall filtration efficiency. Furthermore, the thickness or material of the filter cotton 43 can be adjusted as needed to adapt to different filtration requirements and operating environments.

[0061] like Figure 8 As shown, the first filter plate 41 includes a first base plate 411, two first side plates 412, and two second side plates 413. The two first side plates 412 are arranged opposite each other in the second direction X and are both connected to the first base plate 411. The two second side plates 413 are arranged opposite each other in the third direction Y and are both connected to the first base plate 411. One of the two first side plates 412 has a flange 40 extending in the third direction Y. The flange 40 not only enhances the sealing performance but also serves as an auxiliary structure for installation and fixation, making it easier to install the dust filter 4 onto the frame 1 or other supporting structures.

[0062] like Figure 9As shown, the second filter plate 42 includes a second cover plate 421, two third side plates 422, and two fourth side plates 423. The second cover plate 421 and the first bottom plate 411 are spaced apart in the first direction Z. The two third side plates 422 are opposite to each other in the second direction X and are both connected to the second cover plate 421. The two fourth side plates 423 are opposite to each other in the third direction Y and are both connected to the second cover plate 421. The third side plates 422 and fourth side plates 423 abut against the first bottom plate 411 and the second cover plate 421 in the first direction Z, forming a robust structure. This ensures that the filter cotton 43 or other filter materials remain stable during use, are not easily deformed or displaced, and improves the overall strength and durability of the entire dust filter element 4, enabling it to withstand greater pressure and stress.

[0063] like Figure 6 , Figure 8 and Figure 9 As shown, the first base plate 411 has a first through hole 101. The fourth side plate 423 is connected to a connecting plate 424 extending along the second direction X, and the connecting plate 424 has a second through hole 102. Specifically, the top end of the fourth side plate 423 is connected to the second cover plate 421, the bottom end of the fourth side plate 423 is connected to the connecting plate 424, and the connecting plate 424 has a second through hole 102 extending along the first direction Z.

[0064] The first through hole 101 and the second through hole 102 are interconnected in the first direction Z. The dustproof net 1002 also includes a first fixing member 7, which passes through the first through hole 101 and the second through hole 102 to fix the two filter plates together.

[0065] like Figure 8 As shown, the first base plate 411 has a first opening 107, and the second cover plate 421 has a second opening 108 opposite to the first opening 107. Filter cotton 43 is disposed between the first base plate 411 and the second cover plate 421, covering the first opening 107 and the second opening 108. Therefore, the first base plate 411 and the second cover plate 421 clamp and fix the edges of the filter cotton 43, and the middle part of the filter cotton 43 is corresponding to the first opening 107 and the second opening 108, so that pollutants (dust) are filtered through the middle part of the filter cotton 43.

[0066] Both the first base plate 411 and the second cover plate 421 are ring-shaped structures, such as rectangular ring structures. When the first base plate 411 and the second cover plate 421 clamp and fix the edge of the filter cotton 43, the first base plate 411 and the second cover plate 421 can evenly distribute the pressure applied to the dust filter 4, reducing local stress concentration and thus reducing the risk of deformation or damage.

[0067] like Figure 8As shown, the first side plate 412 has at least one limiting opening 109. The limiting member 3 is detachably disposed within the limiting opening 109 to fix the dust filter 4 and prevent the dust filter 4 from shaking within the frame 1. Furthermore, during installation, the limiting member 3 can be quickly positioned and fixed within the limiting opening, reducing installation time and complexity.

[0068] like Figure 6-8 As shown, the flanged portion 40 has a first connecting port 103, the partition plate 2 has a second connecting port 104, and the pressure strip plate 6 has a third connecting port 105. The first connecting port 103, the second connecting port 104, and the third connecting port 105 are interconnected in the first direction Z. The dustproof net 1002 also includes a second fixing member 8, which passes through the first connecting port 103, the second connecting port 104, and the third connecting port 105.

[0069] By providing interconnected connection ports on the flange 40, partition plate 2, and pressure strip plate 6, and using a second fastener 8 to pass through them, a unified fixing structure is formed, effectively preventing the components from shifting or loosening during use and ensuring the stability of the dustproof net 1002. Furthermore, the flange 40, partition plate 2, and pressure strip plate 6 can be simultaneously fixed by a single second fastener 8, making installation and disassembly simpler and reducing installation steps and time.

[0070] The aforementioned limiting component 3 and fixing component can include, but are not limited to, fasteners such as bolts.

[0071] like Figure 6 , Figure 7 as well as Figure 10 As shown, the frame 1 includes two first frame plates 11 and two second frame plates 12. The two first frame plates 11 are arranged opposite each other in the second direction X, and the two second frame plates 12 are arranged opposite each other in the third direction Y. The first frame plates 11 and the second frame plates 12 are connected. A limiting member 3 is installed on the first frame plate 11, and one of the two second frame plates 12 has at least one limiting hole 106. The pressure strip plate 6 has an extension 60 extending along the second direction X, and the extension 60 is detachably disposed in the limiting hole 106.

[0072] The aforementioned limiting hole 106 provides a clear positioning point, ensuring accurate alignment of the extension 60 during installation. This precise positioning helps improve the assembly accuracy and consistency of the entire structure. By placing the extension 60 of the pressure strip 6 within the limiting hole 106, a robust connection is formed, effectively preventing the pressure strip 6 from shifting or loosening during use, ensuring the stability of the entire frame 1. The detachable design of the extension 60 simplifies the installation and removal process. Users can easily insert or remove the extension 60 from the limiting hole 106, simplifying maintenance and replacement procedures.

[0073] like Figure 10 As shown, the pressure strip 6 includes a third pressure plate 61 and two fifth side plates 62. The third pressure plate 61 is disposed on the partition plate 2, and the two fifth side plates 62 are disposed opposite each other in the second direction X and are both connected to the third pressure plate 61 to form a stable structure. Each fifth side plate 62 has an extension 60 extending along the second direction X, providing a clear positioning and alignment reference for the installation of the pressure strip 6, making the installation process simpler and more precise, and ensuring good fit between the components.

[0074] The dust filter 1002 also includes a connector 9, which is located between the inner wall of the frame 10 and the outer wall of the dust filter 4. The connector 9 fills the gap between the frame 10 and the dust filter 4, significantly improving the overall sealing effect. This helps prevent dust, impurities, and other particles from penetrating through the connection, ensuring that all airflow must pass through the dust filter 4, thereby improving filtration efficiency and ensuring higher quality air purification.

[0075] The aforementioned connector 9 includes, but is not limited to, adhesive strips, and its main purpose is to improve the sealing between the frame 10 and the dust filter 4.

[0076] The installation steps for the aforementioned dustproof net 1002 are roughly as follows:

[0077] (1) Install the dust filter 4 at the bottom of the frame 10 of the frame 1. If the limiting member 3 is fixedly connected to the inner wall of the frame 10, the dust filter 4 is placed at the bottom of the frame 10 at an angle. If the limiting member 3 is detachably connected to the inner wall of the frame 10, it can be placed at the bottom of the frame 10 in any way.

[0078] (2) The pressure plate 6 is detachably mounted on the flange 40 via the guide 5, and the extension 60 of the pressure plate 6 is inserted into the limiting hole 106 of the frame 1 to simplify the installation and disassembly process and reduce the reliance on tools.

[0079] (3) The flanged part 40 has a first connecting port 103, the partition plate 2 has a second connecting port 104, and the pressure strip plate 6 has a third connecting port 105. Since the first connecting port 103, the second connecting port 104, and the third connecting port 105 are interconnected in the first direction Z, the flanged part 40, the partition plate 2, and the pressure strip plate 6 can be fixed simultaneously by a second fixing member 8, making the installation and disassembly process simpler and reducing the installation steps and time. Therefore, when disassembling and assembling the dustproof net 1002, only the second fixing member 8 on the pressure strip plate 6 needs to be removed to replace or maintain the dustproof filter 4, thereby improving the replacement and maintenance efficiency.

[0080] This application uses a clamping strip 6 to snap onto the frame 1 to fix the dust filter 4 within the frame 1. Since the clamping strip 6 is detachable, it eliminates the need for excessive screw removal, reducing assembly and disassembly time and tool dependence. Therefore, the dust filter 4 can be replaced or maintained simply by removing and installing the clamping strip 6, improving the efficiency of dust filter replacement or maintenance. Furthermore, the dust filter 4 can be removed from inside the frame 10 without requiring sufficient space for replacement or maintenance, allowing for the side-by-side arrangement of multiple cabinets 100 and improving the space utilization of the cabinet 100's on-site environment.
