Description

Technical Field

[0001] The present invention relates to the technical field of servers, and in particular to a dustproof device and a server cabinet. Background Art

[0002] Server cabinets require continuous and efficient ventilation and heat dissipation. Existing technologies typically employ open vents or static dust filters. The former creates an unobstructed ventilation path, but this allows dust to penetrate freely, causing dust accumulation on electronic components within the server, localized overheating, and deteriorating stability. The latter, while capable of intercepting large particles, gradually clogs the pores of the dust filter due to dust deposition over time, exponentially increasing airflow resistance and drastically reducing heat dissipation efficiency. In extreme cases, this can trigger server overheating and shutdown.

[0003] Open vents maintain short-term heat dissipation at the expense of equipment dust protection, while static dust filters, in exchange for temporary protection, are forced to endure irreversible degradation of heat dissipation performance. This mutual exclusivity between dust protection and heat dissipation makes existing technologies unable to meet the combined needs of server rooms for a long-term clean operating environment and sustained, efficient heat dissipation.

[0004] Therefore, there is an urgent need to develop a dust-proof device and a server cabinet that has the ability to dynamically adjust the ventilation cross-sectional area and self-cleaning, so as to block dust intrusion while maintaining the continuous unobstructed heat dissipation channel. Summary of the Invention

[0005] The present invention provides a dustproof device and a server cabinet, so as to at least solve the problem of dust clogging of a server cabinet provided with a dust filter plate during long-term use in the related art.

[0006] The present invention provides a dustproof device, comprising a dust filter plate, a plurality of dust filter plates, a plurality of drive assemblies, a cleaning assembly, and a plurality of linkage assemblies. The dust filter plate is arranged at the ventilation port of the cabinet, and the dust filter plate has a plurality of rows of air inlet hole groups spaced apart in a first direction, and each row of the air inlet hole groups includes a plurality of air inlet holes spaced apart in a second direction orthogonal to the first direction; a plurality of dust filter plates are respectively arranged on the first side of the dust filter plate corresponding to the plurality of rows of the air inlet hole groups, and respectively rotate around an axis parallel to the second direction; a plurality of drive assemblies are arranged on the dust filter plate, and respectively drive the plurality of dust filter plates to rotate to adjust the opening and closing angles of the plurality of dust filter plates relative to the dust filter plate; a cleaning assembly is arranged on the second side of the dust filter plate, and the cleaning assembly includes a plurality of movably arranged cleaning members; a plurality of linkage assemblies drive the plurality of cleaning members to pass through the plurality of air inlet holes in response to the rotation of the plurality of dust filter plates to achieve cleaning.

[0007] The present invention also provides a server cabinet, comprising a cabinet body, wherein the side wall of at least one side of the cabinet body is provided with a plurality of ventilation openings spaced apart and distributed along the height direction of the cabinet body; and the plurality of dustproof devices are respectively provided at the ventilation openings.

[0008] The present invention achieves the coordinated operation of dust prevention and self-cleaning functions through a linkage component. Multiple rows of independently controllable dust shields adjust the opening and closing angles according to actual needs, ensuring the cabinet's ventilation and heat dissipation requirements while effectively blocking dust ingress. Secondly, a linkage component automatically triggers the cleaning action of the cleaning component while the dust shield rotates to adjust the ventilation volume, allowing the cleaning components to pass through the corresponding air inlets for real-time dust removal, resolving the technical problem of traditional dust prevention devices being prone to dust accumulation and clogging. This not only extends the service life of the dust filter plates but also reduces the frequency of manual maintenance, enabling intelligent and automated operation of the dust prevention system.

[0066] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0068] In order to enable those skilled in the art to better understand the solutions of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0069] Figure 1 A three-dimensional structural diagram of a server cabinet provided in an embodiment of the present invention; Figure 2 A three-dimensional diagram of a dustproof device provided by an embodiment of the present invention from a first perspective; Figure 3 A partial view of the dustproof device provided by an embodiment of the present invention from a second perspective.

[0070] An embodiment of the present invention provides a dustproof device, such as Figures 1 to 3As shown, the dust-proof device includes a dust filter plate 1, multiple dust-proof plates 2, multiple drive components 3, a cleaning component 4 and multiple linkage components 5. The dust filter plate 1 is arranged at the ventilation port of the cabinet, and the dust filter plate 1 has multiple rows of air inlet hole groups spaced apart in a first direction, and each row of air inlet hole groups includes multiple air inlet holes 11 spaced apart in a second direction orthogonal to the first direction; multiple dust-proof plates 2 are respectively arranged on the first side of the dust filter plate 1 corresponding to the multiple rows of air inlet hole groups, and respectively rotate around an axis parallel to the second direction; multiple drive components 3 are arranged on the dust filter plate 1, and respectively drive the multiple dust-proof plates 2 to rotate to adjust the opening and closing angles of the multiple dust-proof plates 2 relative to the dust filter plate 1; the cleaning component 4 is arranged on the second side of the dust filter plate 1, and the cleaning component 4 includes multiple movably arranged cleaning members 41; and the multiple linkage components 5 drive the multiple cleaning members 41 respectively through the multiple air inlet holes 11 in response to the rotation of the multiple dust-proof plates 2 to achieve cleaning.

[0071] According to an embodiment of the present invention, the first direction corresponds to the width of the dust filter plate 1 (i.e., the lateral dimension of the dust filter plate 1), while the second direction orthogonal thereto corresponds to the length of the dust filter plate 1 (i.e., the longitudinal dimension of the dust filter plate 1). As a result, the air inlet hole groups on the dust filter plate 1 are arranged in an alternating pattern along the width, while the multiple air inlet holes 11 within each air inlet hole group are evenly distributed along the length.

[0072] Furthermore, a plurality of dustproof plates 2 are correspondingly arranged at the positions of each air inlet group on the first side of the dust filter plate 1. By precisely adjusting the opening and closing angles of the dustproof plates 2 through the driving component 3, the angle between the dustproof plates 2 and the dust filter plate 1 can be dynamically controlled. The regulation of the airflow flow of the air inlet group is achieved: when heat dissipation needs to be enhanced, the opening and closing angles can be increased to increase the ventilation volume; or, when dust prevention needs to be strengthened, the opening and closing angles can be reduced to limit dust entry. This adjustable structure not only ensures the heat dissipation requirements of the equipment inside the cabinet, but also can flexibly adjust the dust prevention level according to environmental conditions, thereby achieving a coordinated combination of heat dissipation performance and dust prevention effect.

[0073] Specifically, the dust-proof device achieves coordinated ventilation adjustment and self-cleaning via the linkage assembly 5. When the drive assembly 3 adjusts the opening and closing angle of the dust-proof plate 2 relative to the dust filter plate 1, the linkage assembly 5 simultaneously drives the cleaning element 41 through the corresponding air inlet 11 for cleaning. This not only achieves precise control of the ventilation volume but also automatically removes dust accumulated on the dust filter plate 1, effectively solving the problem of reduced ventilation efficiency caused by dust accumulation in traditional dust-proof devices.

[0074] Figure 4 for Figure 2 An enlarged view of point A is shown.

[0075] In an illustrative embodiment, Figures 2 to 4As shown, the drive assembly 3 includes a rotating shaft 31, a drive motor 32, a timing belt 33, and two mounting plates 34. The two mounting plates 34 are symmetrically arranged on either side of the dust filter plate 1 in the second direction. The rotating shaft 31 extends along the second direction, with both ends rotatably mounted on the two mounting plates 34. The drive motor 32 is located outside one of the mounting plates 34, and the output end of the drive motor 32 is connected to the rotating shaft 31 via a timing belt 33. The two ends of the dust shield plate 2 on the side closest to the axis are connected to the rotating shaft 31 via a connecting portion 21.

[0076] According to the above-mentioned configuration, the drive assembly 3 achieves stable and reliable drive of the dust shield 2 through the coordinated design of the rotating shaft 31, the synchronous belt 33, and the drive motor 32. The rotating shaft 31 extends in the second direction and is supported by the mounting plates 34 on both sides, ensuring smooth rotation. The drive motor 32 drives the rotating shaft 31 to rotate via the synchronous belt 33, which has the advantages of precise transmission and low noise. The dust shield 2 is fixedly connected to the rotating shaft 31 via the connecting portion 21, so that the torque of the drive motor 32 can be effectively converted into the opening and closing movement of the dust shield 2. This structural design not only ensures the accuracy and response speed of the angle adjustment of the dust shield 2, but also improves the rigidity and durability of the overall structure through the symmetrical layout of the mounting plates 34.

[0077] According to an embodiment of the present invention, Figure 3 As shown, the main structure of the dust filter plate 1 is provided with side panels 13 on both sides of the longitudinal direction (second direction). The two side panels 13 protrude outward from the second side (usually the outer side) of the dust filter plate 1, forming a reliable mounting base for mounting the mounting plate 34. The protruding configuration of the side panels 13 not only increases the structural strength of the dust filter plate 1, but also ensures the installation stability of the drive assembly 3 and the linkage assembly 5.

[0078] Figure 5 A structural diagram of the linkage component provided in an embodiment of the present invention.

[0079] In an illustrative embodiment, Figure 2 and Figure 5 As shown, one end of the cleaning member 41 is connected to the second side of the dust filter plate 1 through an elastic rope 42, and the other end is connected to the linkage assembly 5 through a traction rope 43; wherein, the traction rope 43 passes through the air inlet hole 11, and the traction rope 43 is retracted and released by the linkage assembly 5, so that the cleaning member 41 reciprocates through the air inlet hole 11 to clean the air inlet hole 11.

[0080] According to the above-mentioned setting method, when the linkage component 5 tightens the traction rope 43, it drives the cleaning member 41 to pass through the air inlet 11 for dust removal; then the restoring force of the elastic rope 42 causes the cleaning member 41 to automatically reset, forming a reciprocating cleaning motion, ensuring that the cleaning member 41 can accurately pass through the air inlet 11 for effective cleaning; the arrangement of the traction rope 43 passing through the air inlet 11 enables the cleaning action to be mechanically linked with the opening and closing of the dustproof plate 2, and automatic cleaning can be completed without additional power, thereby improving the self-maintenance capability and long-term operation reliability of the dustproof device.

[0081] According to an embodiment of the present invention, Figure 3 As shown, the second side of the dust filter plate 1 is also equipped with multiple auxiliary plates 12, spaced evenly along the width (first direction). These auxiliary plates 12 are made of high-strength material and securely connected to the dust filter plate 1 via welding or bolting. They provide a reliable anchor point for the elastic cord 42, ensuring that the cleaning element 41 maintains a stable trajectory during reciprocating motion. The spaced distribution of the auxiliary plates 12 prevents interference during the cleaning process.

[0082] Figure 6 A cross-sectional view of a linkage assembly provided in an embodiment of the present invention.

[0083] In an illustrative embodiment, Figures 4 to 6 As shown, the linkage assembly 5 includes a traction shaft 51, two torsion springs 54, multiple triggering portions 52, and a receiving portion 53. The traction shaft 51 extends along the second direction, with its ends rotatably mounted on two mounting plates 34. The traction rope 43 is connected to the circumferential surface of the traction shaft 51. The two torsion springs 54 connect the ends of the traction shaft 51 to the two mounting plates 34, respectively, to apply a reset torque to the traction shaft 51. The multiple triggering portions 52 are equiangularly distributed around the circumference of the rotating shaft 31, with recesses formed between adjacent triggering portions 52. The multiple triggering portions 52 rotate with the rotating shaft 31. The receiving portion 53 is disposed on the traction shaft 51 and initially faces the rotating shaft 31 and is parallel to the first direction. When the rotating shaft 31 rotates and drives the dust shield 2 to increase its opening and closing angle, at least one triggering portion 52 abuts against a first side of the receiving portion 53, causing the receiving portion 53 to drive the traction shaft 51 to rotate and wind the traction rope 43. When the recesses face the receiving portion 53, the two torsion springs 54 reset the traction shaft 51 and release the traction rope 43.

[0084] Specifically, when the rotating shaft 31 drives the dust shield 2 to increase its opening and closing angle, the trigger portion 52 pushes the receiving portion 53, causing the traction shaft 51 to rotate and wrap around the traction rope 43, driving the cleaning member 41 to clean. When the recess between the two trigger portions 52 aligns with the receiving portion 53, the reset torque of the torsion spring 54 causes the traction shaft 51 to quickly rotate and release the traction rope 43. The mechanical coordination between the trigger portion 52 and the receiving portion 53 ensures that the cleaning action is completely synchronized with the opening and closing of the dust shield 2. The elastic reset characteristics of the torsion spring 54 enable the automatic retraction and extension of the traction rope 43. The multiple trigger portions 52 distributed at equal angles enable the cleaning action to be triggered multiple times during the rotation of the dust shield, improving the cleaning frequency and effectiveness. The overall structure is simple and reliable, with low maintenance costs.

[0085] According to an embodiment of the present invention, the trigger portion 52 and the receiving portion 53 both adopt a plate-like structure, which has the characteristics of simple structure and high strength. The fan-shaped recess formed between two adjacent trigger portions 52 is preferably designed with an angle of 20°. This angle setting ensures sufficient triggering frequency and avoids interference between adjacent trigger portions 52. This precise angle configuration allows the dust plate 2 to trigger a cleaning action every time it rotates 20°, achieving the best match between the cleaning frequency and the rotation angle of the dust plate 2. The trigger portion 52 and the receiving portion 53 of the plate-like structure are combined with the design of the fan-shaped recess, which not only improves the reliability of mechanical contact, but also ensures the accuracy and consistency of each triggering action, so that the cleaning component 4 can maintain stable working performance throughout the entire process of the dust plate 2 rotating.

[0086] The receiving portion 53 is further configured to pull the cleaning member 41 to complete cleaning when the dustproof plate 2 rotates 20°, and to disengage from the trigger portion 52 and accurately return to the initial position under the action of the torsion spring 54.

[0087] According to an embodiment of the present invention, four trigger parts 52 are provided, and two adjacent trigger parts 52 are evenly distributed in the circumferential direction of the rotating shaft 31 at intervals of 20°. When the system is in working condition, the dustproof plate 2 has an initial opening and closing angle of 40° and a maximum opening and closing angle of 120°. When the dustproof plate 2 is at an initial opening and closing angle of 40°, the first trigger part 52 just forms an abutment state with the receiving part 53; as the opening and closing angle of the dustproof plate 2 gradually increases to a maximum opening and closing angle of 120°, due to the distribution setting of the interval angle (i.e., 20°), it is ensured that the four trigger parts 52 can complete four effective triggers with the receiving part 53 in sequence, thereby realizing multiple cleaning action triggering of the dustproof plate 2 throughout the entire opening and closing stroke. This design ensures that no matter what opening and closing angle position the dustproof plate 2 is in, a uniform and reliable cleaning triggering effect can be obtained.

[0088] In an illustrative embodiment, Figure 4As shown, the mounting plate 34 is provided with a stopper 341; the traction shaft 51 is provided with a limiting portion 511; wherein, when the traction shaft 51 is reset, the limiting portion 511 and the stopper 341 abut against each other to overcome the reset torque, so that the receiving portion 53 remains in the initial position.

[0089] Specifically, when the torsion spring 54 drives the traction shaft 51 to rotate and reset, the limiter 511 abuts against the stopper 341 on the mounting plate 34, effectively absorbing the remaining reset torque to prevent overshoot and ensuring that the receiving portion 53 accurately stops at its initial position parallel to the first direction, ready for the next cleaning action. This mechanical limit not only improves the reliability of the linkage assembly 5 but also eliminates position errors during the reset process through physical limiting, ensuring that the trigger position of each cleaning action is consistent, and that the opening and closing angle of the dust shield and the cleaning stroke always maintain a precise correspondence.

[0090] In an illustrative embodiment, Figure 6 As shown, the second side of the receiving portion 53 opposite to the first side of the receiving portion 53 is configured as a slope 531; the receiving portion 53 is arranged in the radial sliding direction of the traction shaft 51 in the give way groove 512 of the traction shaft 51, and moves between an initial position extending out of the give way groove 512 and a retracted position at least partially retracted into the give way groove 512; wherein, when the rotating shaft 31 rotates and drives the dustproof plate 2 to reduce the opening and closing angle, at least one trigger portion 52 abuts against the second side of the receiving portion 53 to move the receiving portion 53 from the initial position to the retracted position, and when the recess faces the receiving portion 53, the receiving portion 53 is reset by gravity.

[0091] According to the above arrangement, when the dust shield 2 decreases its opening angle, the trigger portion 52 slides along the inclined surface 531, pushing the receiving portion 53 into the clearance groove 512, thus avoiding mechanical interference. When the recess aligns with the receiving portion 53, the receiving portion 53 automatically returns to its initial position under the action of gravity. This mechanical avoidance ensures the smooth closing of the dust shield 2; the guiding effect of the inclined surface 531 ensures a smooth transition of the trigger portion 52; and the gravity reset mechanism eliminates the need for additional elastic elements, simplifying the structure.

[0092] This two-way trigger mechanism enables the linkage component 5 to trigger cleaning when the dustproof plate 2 opens, and to automatically avoid when the dustproof plate 2 closes, thereby achieving conflict-free coordinated operation of the dustproof and cleaning functions.

[0093] In an illustrative embodiment, Figure 6 As shown, a limiting groove 513 extending radially of the traction shaft 51 is provided in the clearance groove 512, and the width or thickness of the limiting groove 513 is greater than the clearance groove 512; wherein, limiting protrusions 532 that slide with the limiting groove 513 are provided on opposite sides of the receiving part 53.

[0094] Specifically, the widened or thickened design of the limiting groove 513 provides a stable guide track for the limiting protrusion 532, which not only ensures that the receiving part 53 can slide smoothly in the giving way groove 512 to complete the avoidance action, but also prevents the receiving part 53 from falling out or deviating through mechanical limitation.

[0095] According to an embodiment of the present invention, Figure 6 As shown, in the axial cross-sectional view of the traction shaft 51, the thickness of the limit groove 513 is greater than the clearance groove 512. At this time, the limit protrusion 532 is arranged at the end of the first side and the second side of the receiving part 53, forming a sliding fit with the limit groove 513, and preventing the receiving part 53 from sliding out of the clearance groove 512.

[0096] According to another embodiment of the present invention, the width of the limiting groove 513 is greater than the giving way groove 512 (i.e., the dimension in the second direction). At this time, the limiting protrusion 532 is arranged on both sides of the receiving portion 53 in the second direction, i.e., the two sides adjacent to the first side and the second side.

[0097] Figure 7 A three-dimensional diagram of a server cabinet provided by an embodiment of the present invention;

[0098] In an illustrative embodiment, Figure 7 As shown, the dustproof device further includes a temperature sensor 6 disposed within the cabinet for monitoring the real-time temperature within the cabinet; and a control unit configured to control the drive motor 32 to increase the opening and closing angle of the dustproof plate 2 when the real-time temperature value increases and reaches a set threshold. The opening and closing angle increases in a stepwise manner as the temperature increases. When the real-time temperature value decreases, the drive motor 32 is controlled to decrease the opening and closing angle of the dustproof plate 2.

[0099] In detail, the temperature sensor 6, the drive motor 32 and the control unit are electrically connected. The temperature sensor 6 sends the detected temperature signal to the control unit. When the temperature sensor 6 detects that the temperature inside the cabinet rises and reaches a preset temperature threshold, the control unit controls the drive motor 32 to drive the shaft 31 to rotate forward, thereby increasing the opening and closing angle of the dustproof plate 2. When the temperature sensor 6 detects that the temperature inside the cabinet drops, the control unit controls the drive motor 32 to drive the shaft 31 to rotate in the reverse direction, thereby reducing the opening and closing angle of the dustproof plate 2.

[0100] Furthermore, a stepped temperature control strategy is adopted. When the internal temperature of the cabinet is 20°C, the opening and closing angle of the dust shield 2 is 40°; when the temperature rises to 25°C, the angle increases to 60°; when the temperature reaches 30°C, the angle is adjusted to 80°; when the temperature continues to rise to 35°C, the angle expands to 100°; and under 40°C operating conditions, the dust shield 2 is fully opened to a maximum angle of 120°. This single adjustment of the opening and closing angle of 20° perfectly matches the 20° interval distribution of the trigger unit 52, ensuring that the cleaning action is accurately triggered every time the temperature rises by one step and the dust shield 2 rotates 20°. The three-way linkage design of temperature, angle, and cleaning ensures that the ventilation volume adjustment and the self-cleaning process are completely synchronized, achieving both precise temperature control and ensuring that the dust shield receives timely cleaning and maintenance at each working position.

[0101] In an illustrative embodiment, Figure 7 As shown, the dustproof device further includes a buzzer 7, which is arranged in the cabinet and is configured to trigger an alarm when the real-time temperature value exceeds a set over-temperature threshold.

[0102] According to the above configuration, buzzer 7 is electrically connected to temperature sensor 6. When temperature sensor 6 detects that the internal temperature of the cabinet exceeds the preset over-temperature threshold (40°C), dust shield 2 rotates to its maximum opening angle of 120° to achieve maximum ventilation and heat dissipation. Buzzer 7 also sounds an alarm signal, prompting personnel to promptly address the over-temperature condition.

[0103] In an illustrative embodiment, Figure 3 As shown, the cleaning assembly 4 further includes a plurality of dust collecting boxes 44 extending along the second direction and respectively disposed below the plurality of cleaning members 41 corresponding to the plurality of rows of air inlet hole groups.

[0104] Specifically, the cleaning assembly 4 is equipped with multiple dust collection boxes 44 extending along its length (the second direction). These dust collection boxes 44 are positioned below each row of air inlet holes, precisely aligning with the movement trajectory of the cleaning element 41. As the cleaning element 41 performs its reciprocating cleaning motion, dust and impurities removed from the air inlet holes 11 fall directly into the dust collection boxes 44 below. This ensures immediate dust collection, prevents secondary contamination, improves the cleaning system's actual dust removal efficiency, and simplifies dust removal during maintenance.

[0105] According to an embodiment of the present invention, Figure 3As shown, when a dust box 44 is installed, the top ends of the elastic cords 42 of the cleaning elements 41 corresponding to the top row of air inlet holes are fixed to the auxiliary plate 12, while the elastic cords 42 of the cleaning elements 41 in the remaining rows are directly fixed to the bottom surface of the dust box 44 below. This layered fixing design ensures that all cleaning elements 41 are stably fixed and supported, and the provision of the top auxiliary plate 12 avoids the problem of a lack of fixing points for the top cleaning elements 41.

[0106] According to an embodiment of the present invention, the auxiliary plate 12 is integrally formed with the same material as the dust filter plate 1 , thereby ensuring connection strength.

[0107] Figure 8 This is a structural diagram of a cleaning element provided in an embodiment of the present invention.

[0108] In an illustrative embodiment, Figure 8 As shown, the cleaning member 41 includes an elastic body 411 and bristles 412. The elastic body 411 is configured as a cylinder, and the cross-sectional diameter of the elastic body 411 is smaller than the diameter of the air inlet 11; the bristles 412 are evenly distributed on the circumferential surface of the elastic body 411.

[0109] The cleaning element 41 adopts a composite structure design of an elastic body 411 and bristles 412. The diameter of the cylindrical elastic body 411 is slightly smaller than the air inlet hole 11, ensuring that it can pass through the hole smoothly without getting stuck. The bristles 412 evenly distributed on the surface of the elastic body 411 can clean the inner wall of the air inlet hole 11 in all directions during the reciprocating motion, effectively removing accumulated dust and impurities. The flexible characteristics of the elastic body 411 enable it to adapt to slight deviations in different apertures, ensuring the cleaning effect while avoiding damage to the hole wall. This design not only achieves an efficient and thorough cleaning effect, but also ensures long-term reliability through a simple mechanical structure, greatly reducing maintenance costs.

[0110] According to an embodiment of the present invention, the cleaning member 41 adopts an elastic body 411 made of sponge material, the flexibility of which can ensure smooth passage through the air inlet 11 and drive the surface bristles 412 to effectively remove dust accumulated on the hole wall.

[0111] According to an embodiment of the present invention, the working principle of the dustproof device is as follows: when the temperature inside the cabinet rises, the temperature sensor 6 triggers the drive motor 32 to drive the dustproof plate 2 to rotate upward. At this time, the rotating shaft 31 rotates counterclockwise, driving the trigger part 52 to push the receiving part 53, causing the traction shaft 51 to rotate clockwise and tighten the traction rope 43, pulling the cleaning part 41 through the air inlet 11 to complete a cleaning action; after the trigger part 52 is disengaged, the torsion spring 54 resets the traction shaft 51. This linkage mechanism ensures that the dustproof plate 2 can automatically clean the air inlet 11 every time it is opened, which not only ensures the ventilation and heat dissipation effect, but also prevents the dust filter plate 1 from being blocked. When the temperature drops, the dustproof plate 2 rotates downward, the rotating shaft 31 rotates clockwise, and the trigger part 52 pushes the receiving part 53 to retract the clearance slot 512 through the inclined surface 531, avoiding unnecessary cleaning actions and effectively extending the service life of the cleaning component 4. The entire device automatically adjusts the opening and closing angle of the dustproof plate 2 through temperature sensing: when the temperature rises, the opening and closing angle is increased to enhance ventilation, and when the temperature drops, the opening and closing angle is reduced to enhance dust prevention, achieving an intelligent balance between heat dissipation and dust prevention.

[0112] The embodiment of the present invention further provides a server cabinet, such as Figure 1 and Figure 7 As shown, it includes a cabinet 8, and the side wall of at least one side of the cabinet 8 is provided with multiple ventilation holes 81 distributed at intervals along the height direction of the cabinet 8; the above-mentioned dustproof devices, multiple dustproof devices are respectively arranged at the ventilation holes 81.

[0113] According to an embodiment of the present invention, Figure 1 As shown, a cabinet door 82 is provided on one side of the cabinet body 8, and a plurality of vents 81 evenly distributed along the height direction are provided on both sides adjacent to the cabinet door 82. Each vent 81 is equipped with the aforementioned dustproof device.

[0114] Figure 9 for Figure 7 An enlarged view of point B is shown.

[0115] In an illustrative embodiment, Figure 3 、 Figure 7 and Figure 9 As shown, the server cabinet further includes a connection assembly 9, which includes a magnetic unit 91, a magnetized unit 92, a first clip 93, and a second clip 94. The magnetic unit 91 is disposed in the mounting slot 83 of the cabinet 8 and is located at the upper edge of the vent 81; the magnetized unit 92 is disposed at the top of the dust filter plate 1 facing the cabinet 8 and magnetically engages with the magnetic unit 91; the first clip 93 is disposed on the cabinet 8 and is located at the lower edge of the plurality of vents 81; and the second clip 94 is disposed at the bottom of the dust filter plate 1 facing the cabinet 8 and engages with the first clip 93.

[0116] Detailed, such as Figure 9As shown, the first buckle 93 includes a first horizontal portion 931 extending in the horizontal direction, and a first vertical portion 932 arranged perpendicular to the first horizontal portion 931. The first horizontal portion 931 and the first vertical portion 932 form a first card slot 933 of the magnetic unit 91 with an opening parallel to the vertical direction with the outer wall of the cabinet 8; Figure 3 As shown, the second clip 94 includes a second horizontal portion 941 extending in the second direction, and a second vertical portion 942 arranged perpendicular to the second horizontal portion 941. The second horizontal portion 941 and the second vertical portion 942 form a second slot 943 with the second side of the dust filter plate 1, which opens parallel to the first direction and faces the magnetically attracted unit 92. The first slot 933 and the second slot 943 are snap-fitted together.

[0117] Specifically, a dedicated mounting groove 83 is provided at each vent 81 of the cabinet 8, and a magnetic unit 91 is embedded as an upper fixing point. A magnetic unit 92 that matches the magnetic unit 91 is fixedly installed on the top of the corresponding dust filter plate 1, and the two are initially positioned by magnetic attraction. In particular, the outer surface of the magnetic unit 92, the second vertical portion 942 of the second clip 94, and the outer surface of the side panels 13 on both sides of the dust filter plate 1 are kept flush to ensure an all-round seal between the dust filter plate and the cabinet, effectively preventing dust from entering through the side gaps. Furthermore, a first clip 93 is provided on the lower edge of the cabinet 8 to form an upward first slot 933; a second clip 94 extending in the length direction is correspondingly provided at the bottom of the dust filter plate 1 to form a second slot 943. During installation, first align the iron bar on the top of the dust filter plate 1 with the magnetic sheet for adsorption, and then slide horizontally to fully engage and lock the first clip 93 and the second clip 94.
