Description

Technical Field

[0001] The present invention relates to the technical field of communication equipment, and particularly to a communication cabinet with a full-dimensional status monitoring structure. Background Art

[0002] Communication cabinets are widely used in the field of system integration, including but not limited to places such as network wiring rooms, floor distribution rooms, central computer rooms, data computer rooms, control centers, monitoring rooms, and monitoring centers. Common cabinet types include server cabinets, network cabinets, console cabinets, etc. These cabinets are used to provide interfaces with various external devices, where the external devices include but not limited to information devices, control devices, network devices, switch devices, etc., so as to achieve information collection or status control of various external devices. Front-end devices that support the operation of back-end integrated services are installed inside the cabinet, which is the basic bearing facility for the normal operation of system integration services.

[0003] Currently, the environmental adjustment of communication cabinets mainly uses electronic sensors (such as temperature and humidity sensors, dust sensors) in cooperation with controllers and electric actuators to achieve functions such as heat dissipation, dehumidification, and dust removal through program control. However, this technical solution has the following problems: firstly, the ventilation mode is fixed and cannot adapt to environmental changes. The air intake louvers and exhaust fans of traditional cabinets are mostly of fixed opening or constant speed operation and cannot dynamically adjust according to temperature and humidity differences. Continuous air intake in a high-humidity environment easily leads to moisture intrusion into the cabinet, causing condensation. Insufficient ventilation in a high-temperature environment easily causes heat accumulation, and excessive ventilation in a normal environment wastes energy. Secondly, the function integration degree is low, and there is no integrated mechanical control structure. Existing monitoring, transmission, and execution components are independent of each other, requiring multiple power sources and transmission mechanisms to cooperate. The number of parts is large, the installation and maintenance are complex, and it is difficult to achieve the linkage response of temperature and humidity. Summary of the Invention

[0004] (I) Technical Problems to be Solved Aiming at the deficiencies of the prior art, the present invention provides a communication cabinet with a full-dimensional status monitoring structure, which solves the problems of the separation of temperature and humidity control in traditional cabinets, the easy failure of relying on electronic components, the fixed ventilation mode that cannot adapt, the complex maintenance of scattered components, and the lack of intuitive status feedback.

[0005] (II) Technical Solutions To achieve the above object, the present invention provides the following technical solutions: A communication cabinet with a full-dimensional status monitoring structure includes a cabinet body. Air intake ports and air outlet ports are respectively opened on both sides of the cabinet body. A filter screen is arranged on one side of the air intake port. The communication cabinet further includes: A first impeller and a second impeller, which are respectively rotatably installed on both sides of the filter screen and are both located on the path of the incoming air flow; A differential transmission mechanism is installed inside the cabinet. The differential transmission mechanism is used to sense the speed difference between the first impeller and the second impeller and drive the slider to move in different directions accordingly. The slider is mounted on the differential transmission mechanism and is slidably connected to the cabinet. The condition monitoring mechanism, including a humidity sensing mechanism and a temperature sensing mechanism, is used to sense changes in the environment inside the cabinet and correspondingly change the rotational speed between the first and second impellers, thereby driving the slider to move. A ventilation control mechanism, installed on the cabinet, is used to regulate the ventilation within the cabinet. When the first impeller and the second impeller rotate at the same speed, the slider remains stationary under the action of the differential transmission mechanism. When there is a speed difference between the first impeller and the second impeller, the slider moves axially. During the movement of the slider in different directions, the state of the ventilation adjustment mechanism is changed accordingly until the slider stops moving and the ventilation adjustment mechanism maintains the corresponding stable state.

[0006] As a preferred embodiment of the present invention, the differential transmission mechanism includes: The first reciprocating lead screw and the second reciprocating lead screw are both rotatably mounted on the cabinet and are respectively connected to the first impeller and the second impeller for transmission. The threads of the first reciprocating lead screw and the second reciprocating lead screw have opposite directions. The first toothed plate and the second toothed plate are respectively threaded onto the first reciprocating screw and the second reciprocating screw, and the first toothed plate and the second toothed plate are arranged symmetrically. A rotating shaft is arranged between the first toothed plate and the second toothed plate. A gear is rotatably mounted on the rotating shaft. Both the first toothed plate and the second toothed plate mesh with the gear. The slider is fixedly mounted on the top of the rotating shaft. When the first reciprocating screw and the second reciprocating screw rotate at the same speed, the gear idles and the slider remains stationary. When the first reciprocating screw and the second reciprocating screw rotate at different speeds, the tooth plates on both sides move at different speeds, causing the gear and slider to move towards the side with the faster speed.

[0007] As a preferred embodiment of the present invention, the ventilation regulating mechanism includes: Louvers are installed at the air inlet to adjust the airflow area. A through-hole is provided at the top of the cabinet, and an exhaust fan is installed inside the through-hole; A cover plate, movably installed at the through hole, is used to open or close the through hole; The slider is fixedly equipped with a pull rope for the louvers. When the slider moves, it pulls the louvers through the pull rope, changing the opening degree of the louver blades.

[0008] As a preferred embodiment of the present invention, the humidity sensing mechanism includes a moisture-absorbing expansion member fixedly installed in the cabinet and a first friction disc fixedly installed at the free end of the moisture-absorbing expansion member; The moisture-absorbing and expanding component absorbs water and expands, causing the first friction disc to come into contact with the first reciprocating screw, increasing the rotational resistance of the first reciprocating screw, reducing the speed of the first reciprocating screw, and generating a speed difference that drives the slider to move to the right.

[0009] As a preferred embodiment of the present invention, the temperature sensing mechanism includes: The shape memory alloy spring is fixedly connected to the cabinet at one end and is free at the other end. The second friction disc is fixedly installed at the free end of the shape memory alloy spring; The shape memory alloy spring elongates when heated, causing the second friction disc to come into contact with the second reciprocating screw, increasing the rotational resistance of the second reciprocating screw, reducing the speed of the second reciprocating screw, and generating a speed difference that drives the slider to move to the left.

[0010] As a preferred embodiment of the present invention, the moisture-absorbing and expanding component includes a telescopic rod, which is composed of an outer cylinder and an inner rod. The outer cylinder has a cavity filled with modified wood that is fixedly connected to the inner rod. The outer cylinder has a plurality of water-absorbing holes in its circumference.

[0011] As a preferred embodiment of the present invention, when the slider is located in the right region, the louvers at the air inlet are closed or slightly open, the cover is closed, and the exhaust fan stops. When the slider is in the middle area, the louvers at the air inlet are half-open, the cover is closed, and the exhaust fan stops. When the slider is in the left area, the louvers at the air inlet are fully open, the cover is opened, and the exhaust fan is started.

[0012] As a preferred embodiment of the present invention, an observation window is provided on the top of the cabinet, which can be used to determine the environmental conditions inside the cabinet based on the position of the slider.

[0013] In a preferred embodiment of the present invention, a return spring is further provided between the slider and the cabinet. The return spring is in a free state when the slider is in the middle region. When the slider moves to the left or right, the return spring is stretched or compressed and stores elastic potential energy. When the factor causing the speed difference disappears, the return spring releases the elastic potential energy, driving the slider back to the middle region. As a preferred embodiment of the present invention, a vibration motor is provided on the side of the cabinet near the filter screen, and a sensor is provided on the slider. When the slider moves, the sensor triggers the vibration motor to vibrate the filter screen.

[0014] (III) Beneficial Effects Compared with the prior art, the present invention provides a communication cabinet with a full-dimensional status monitoring structure, which has the following beneficial effects: 1. This type of communication cabinet with a full-dimensional status monitoring structure achieves multiple adaptive adjustment effects through the coordinated operation of the differential transmission mechanism and the ventilation adjustment mechanism: When humidity increases, the humidity sensing mechanism increases the resistance of the first reciprocating screw, and the differential transmission mechanism drives the slider to move to the right, closing the louvers and blocking moisture intrusion; when temperature increases, the temperature sensing mechanism increases the resistance of the second reciprocating screw, and the differential transmission mechanism drives the slider to move to the left, fully opening the louvers, opening the top cover, and starting the exhaust fan, forming an enhanced heat dissipation channel; when the environment is normal, the slider automatically returns to the middle area, the louvers are half-open, and the cabinet relies on natural convection to maintain basic ventilation. One slider simultaneously controls three actuators: louvers, cover, and exhaust fan, realizing automatic switching between three modes: "high humidity wind resistance, high temperature strong exhaust, and normal half-open." The transition between the three modes is smooth and does not interfere with each other. At the same time, the same differential transmission mechanism can sense the speed difference, convert the speed difference into slider displacement, and drive the slider to drive the ventilation adjustment mechanism. One mechanism simultaneously realizes the three functions of detection, conversion, and execution, resulting in a highly integrated structure.

[0015] 2. In this type of communication cabinet with a full-dimensional status monitoring structure, the humidity sensing mechanism and the temperature sensing mechanism work together through the same differential transmission mechanism, producing opposing driving effects: the humidity sensing mechanism acts on the first reciprocating lead screw, causing the slider to move to the right; the temperature sensing mechanism acts on the second reciprocating lead screw, causing the slider to move to the left. The two sensing mechanisms share the same differential transmission mechanism and slider, allowing them to independently trigger their respective adjustment actions, while simultaneously coordinating priorities through the slider's balance position. Through collaborative work, the two mechanisms achieve differentiated responses to different environmental factors without requiring any additional switching devices.

[0016] 3. This type of communication cabinet with a full-dimensional status monitoring structure incorporates a status monitoring mechanism. The moisture expansion component uses a telescopic rod structure, which can quickly absorb moisture through the water absorption holes, convert the radial expansion of the modified wood into axial thrust, and directly act on the reciprocating screw through the friction disc. A single moisture expansion component simultaneously achieves three functions: moisture sensing, displacement conversion, and resistance adjustment. Meanwhile, the shape memory alloy spring, as a temperature sensing element, can both detect temperature changes and generate sufficient driving force to press the friction disc, eliminating the need for additional amplification mechanisms. The structure is compact and highly responsive.

[0017] 4. This type of communication cabinet with a full-dimensional status monitoring structure has a top observation window and slider that work together to serve as a status indicator so that maintenance personnel can intuitively judge the environment inside the cabinet, and also as a debugging auxiliary tool to verify the working status of the differential transmission mechanism.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] Please see Figures 1 to 8 The present invention provides a communication cabinet with a full-dimensional status monitoring structure, comprising a cabinet body 1, with air inlets 2 and air outlets 3 respectively on both sides of the cabinet body 1, and a filter 4 disposed on one side of the air inlet 2, and further comprising: The first impeller 5 and the second impeller 6 are respectively rotatably installed on both sides of the filter screen 4, and both are located on the path of the air intake airflow; The differential transmission mechanism 7 is installed inside the cabinet 1. The differential transmission mechanism 7 is used to sense the speed difference between the first impeller 5 and the second impeller 6, and drive the slider 10 to move in different directions accordingly. Slider 10 is mounted on the differential transmission mechanism 7 and slidably connected to the cabinet 1. The status monitoring mechanism 9, including a humidity sensing mechanism and a temperature sensing mechanism, is used to sense changes in the environment inside the cabinet 1 and correspondingly change the rotational speed between the first impeller 5 and the second impeller 6, thereby driving the slider 10 to move. Ventilation adjustment mechanism 8 is installed on cabinet 1 and is used to adjust the ventilation state inside cabinet 1; When the first impeller 5 and the second impeller 6 rotate at the same speed, the slider 10 remains stationary under the action of the differential transmission mechanism 7. When there is a speed difference between the first impeller 5 and the second impeller 6, the slider 10 moves axially. During the movement of the slider 10 in different directions, the state of the ventilation adjustment mechanism 8 is changed accordingly until the slider 10 stops moving and the ventilation adjustment mechanism 8 maintains the corresponding stable state.

[0032] By adopting the above technical solution, when external airflow enters the cabinet 1, the airflow simultaneously drives the first impeller 5 and the second impeller 6 to rotate. Under normal circumstances, the airflow speeds through the first impeller 5 and the second impeller 6 are basically the same, and the differential transmission mechanism 7 keeps the slider 10 stationary, with the cabinet in a natural ventilation state. When the humidity or temperature rises, the status monitoring mechanism 9 increases the resistance of the corresponding differential transmission mechanism 7, causing the differential transmission mechanism 7 to generate a speed difference. The slider 10 then moves in a specific direction and mechanically links the ventilation adjustment mechanism 8, automatically switching to a high humidity resistance mode or a high temperature forced exhaust mode.

[0033] Specifically, the differential transmission mechanism 7 includes: The first reciprocating lead screw 71 and the second reciprocating lead screw 72 are both rotatably mounted on the cabinet 1 and are respectively connected to the first impeller 5 and the second impeller 6. The threads of the first reciprocating lead screw 71 and the second reciprocating lead screw 72 are opposite. The first tooth plate 73 and the second tooth plate 74 are respectively threaded onto the first reciprocating screw 71 and the second reciprocating screw 72, and the first tooth plate 73 and the second tooth plate 74 are symmetrically arranged. A rotating shaft 75 is arranged between a first toothed plate 73 and a second toothed plate 74. A gear 76 is rotatably mounted on the rotating shaft 75. Both the first toothed plate 73 and the second toothed plate 74 mesh with the gear 76. A slider 10 is fixedly mounted on the top of the rotating shaft 75. When the first reciprocating screw 71 and the second reciprocating screw 72 rotate at the same speed, the gear 76 spins freely and the slider 10 remains stationary. When the first reciprocating screw 71 and the second reciprocating screw 72 rotate at different speeds, the toothed plates on both sides move at different speeds, causing the gear 76 and the slider 10 to move towards the side with the faster speed.

[0034] By adopting the above technical solution, under normal circumstances, the airflow speeds of the first impeller 5 and the second impeller 6 are basically the same. Therefore, the rotational speeds of the first impeller 5 and the second impeller 6 are consistent, and the first reciprocating screw 71 and the second reciprocating screw 72 also maintain the same rotational speed. This causes the first toothed plate 73 and the second toothed plate 74 to move in opposite directions at the same speed. The gear 76 only rotates without translation, so the slider 10 remains stationary. When environmental factors (such as increased humidity, increased temperature, or clogging of the filter 4) cause a difference in the rotational speeds of the first impeller 5 and the second impeller 6, the two screws (the first reciprocating screw 71 and the second reciprocating screw 72) will rotate in opposite directions without translation. 2) A speed difference is generated between the two gear plates (first gear plate 73 and second gear plate 74), and their moving speeds are no longer equal. Gear 76 is forced to translate, which drives slider 10 to move axially. During the movement of slider 10, it cooperates with ventilation adjustment mechanism 8 to automatically switch ventilation modes according to different environmental conditions. That is, the same differential transmission mechanism 7 can not only sense the speed difference, but also convert the speed difference into the displacement of slider 10, and drive slider 10 to drive ventilation adjustment mechanism 8. One mechanism realizes the three functions of detection, conversion and execution at the same time, realizes closed-loop adaptive control, and has extremely high reliability and environmental adaptability.

[0035] Specifically, the ventilation control mechanism 8 includes: The louver 81 is installed at the air inlet to adjust the airflow area of ​​the air inlet; An exhaust fan 83 is installed inside the through hole 82, which is located at the top of the cabinet 1. A cover plate is movably installed at through hole 82 to open or close through hole 82; The slider 10 is fixedly equipped with a pull rope 84 for the louver 81. When the slider 10 moves, it pulls the louver 81 through the pull rope 84, changing the opening degree of the louver 81.

[0036] By adopting the above technical solution, a spring (not shown in the figure) is installed on the blade shaft 75 of the louver 81. Under normal conditions, the spring keeps the louver 81 in a half-open state. One end of the pull rope 84 is fixed to the slider 10, and the other end passes around the blade linkage plate connected to the louver 81. When the slider 10 moves to the right, the pull rope 84 is tightened, the louver 81 is closed, and the air inlet flow area is reduced; when the slider 10 moves to the left, the pull rope 84 is loosened, and the louver 81 blades rotate in the opening direction under the action of their own springs, increasing the air inlet flow area; when the slider 10 moves to the leftmost end, the louver 81 reaches its maximum opening, thus realizing the adaptive linkage between the position of the slider 10 and the ventilation state inside the cabinet 1. The movement of the slider 10 changes the ventilation state inside the cabinet 1; it also realizes a differentiated ventilation strategy—automatically closing the air inlet when humidity is high to reduce moisture entry, and automatically fully opening the air inlet and opening the top exhaust when temperature is high to enhance heat dissipation.

[0037] Specifically, the humidity sensing mechanism includes a moisture-absorbing expansion member 91 fixedly installed in the cabinet 1 and a first friction disc 92 fixedly installed in the free end of the moisture-absorbing expansion member 91; The moisture-absorbing expansion component 91 absorbs water and expands, causing the first friction disk 92 to abut against the first reciprocating screw 71, increasing the rotational resistance of the first reciprocating screw 71, reducing the rotational speed of the first reciprocating screw 71, and generating a speed difference to drive the slider 10 to move to the right.

[0038] The moisture-absorbing expansion component 91 includes a telescopic rod, which is composed of an outer cylinder 911 and an inner rod 912. The outer cylinder 911 has a cavity and is filled with modified wood 913 that is fixedly connected to the inner rod 912. The outer cylinder 911 has several water-absorbing holes 914 in its circumference.

[0039] By adopting the above technical solution, under normal humidity conditions, the moisture-absorbing expansion component 91 is in a contracted state, and a certain gap is maintained between the first friction disc 92 and the first reciprocating screw 71, so they do not contact each other, and the first reciprocating screw 71 rotates normally. When the ambient humidity increases, humid air enters the cavity of the outer cylinder 911 through the water absorption hole 914, and the modified wood 913 absorbs moisture, its volume expands axially, pushing the inner rod 912 outward. The higher the humidity, the greater the extension. When the inner rod 912 extends, it pushes the first friction disc 92 to gradually approach and eventually press against the first reciprocating screw 71, increasing the rotational resistance of the first reciprocating screw 71 and causing its speed to decrease. Since the speed of the second reciprocating screw 72 is not affected (or is only slightly affected), a speed difference appears between the first reciprocating screw 71 and the second reciprocating screw 72, and the differential transmission mechanism 7 drives the slider 10 to move to the right. As slider 10 moves to the right, the louvers 81 at the air inlet are gradually closed via the pull rope 84, reducing the amount of humid air entering. This creates negative feedback regulation: the higher the humidity, the greater the expansion of the moisture-absorbing expansion element 91, the greater the clamping force of the first friction disc 92, the lower the rotational speed of the first reciprocating screw 71, the greater the rightward movement of slider 10, and the more completely louvers 81 close. When the humidity returns to normal, the moisture-absorbing expansion element 91 loses water and contracts, the first friction disc 92 disengages from the first reciprocating screw 71, the rotational speed of the first reciprocating screw 71 resumes, and slider 10 automatically moves to the left under the action of the differential transmission mechanism 7, reopening louvers 81.

[0040] Specifically, the temperature sensing mechanism includes: a memory alloy spring 93 fixedly installed on one side of the cabinet 1; The shape memory alloy spring 93 has one end fixedly connected to the cabinet 1, and the other end is a free end; The second friction disc 94 is fixedly installed at the free end of the shape memory alloy spring 93; The shape memory alloy spring 93 elongates when heated, causing the second friction disk 94 to come into contact with the second reciprocating screw 72, increasing the rotational resistance of the second reciprocating screw 72, reducing the rotational speed of the second reciprocating screw 72, and generating a speed difference that drives the slider 10 to move to the left.

[0041] By adopting the above technical solution, under normal temperature conditions, the shape memory alloy spring 93 contracts, the second friction disc 94 and the second reciprocating screw 72 do not contact each other, and the second reciprocating screw 72 operates normally. When the internal temperature of the cabinet 1 rises, the shape memory alloy spring 93 extends, pushing the second friction disc 94 to gradually approach and eventually press against the second reciprocating screw 72, increasing the rotational resistance of the second reciprocating screw 72 and causing its speed to decrease. Since the speed of the first reciprocating screw 71 is not affected (or is only slightly affected), a speed difference appears between the first reciprocating screw 71 and the second reciprocating screw 72, and the differential transmission mechanism 7 drives the slider 10 to move to the left. During the leftward movement of the slider 10, the louvers 81 at the air inlet gradually open. On the other hand, when the slider 10 moves to the left side area, a switch is triggered, opening the top cover and starting the exhaust fan 83. At this time, the air inlet is fully open, the top through hole 82 is open, and the exhaust fan 83 forces air out, forming a smooth heat dissipation channel from the air inlet to the top, and the heat inside the cabinet is quickly discharged. The higher the temperature, the greater the elongation of the memory alloy spring 93, the greater the clamping force of the second friction disc 94, the lower the rotational speed of the second reciprocating screw 72, the greater the leftward movement distance of the slider 10, and the higher the heat dissipation intensity, thereby achieving automatic enhanced heat dissipation at high temperatures.

[0042] Specifically, when slider 10 is located in the right area, the louver 81 at air inlet 2 is closed or slightly open, the cover is closed, and exhaust fan 83 stops. When slider 10 is in the middle area, louver 81 at air inlet 2 is half open, cover is closed, and exhaust fan 83 stops. When slider 10 is in the left area, the louver 81 at air intake 2 is fully open, the cover is opened, and exhaust fan 83 is started.

[0043] By adopting the above technical solution, when the slider 10 is located in the right area, corresponding to the situation of increased humidity or filter 4 blockage, the louvers 81 of the air inlet are closed or at a very small opening under the pull of the pull cord 84, and the top cover remains closed, effectively blocking the entry of high-humidity external air into the cabinet 1. When the slider 10 is located in the middle area, corresponding to the situation of normal temperature and humidity, the cover is closed and the exhaust fan 83 stops. The cabinet 1 relies on natural convection between the air inlet and the air outlet for basic ventilation and heat dissipation to meet daily operation needs. When the slider 10 is located in the left area, corresponding to the situation of increased temperature inside the cabinet 1, the louvers 81 reach their maximum opening, increasing the convection heat dissipation area inside the cabinet 1. At the same time, the slider 10 triggers the switch, opens the top cover and starts the exhaust fan 83, forcibly expelling the heat inside the cabinet 1 through the exhaust fan 83, and a large amount of cold air is brought in from the air inlet, quickly reducing the temperature inside the cabinet. This zoned control strategy makes the three modes logically clear and reliable in operation: when the humidity is high, the air intake is cut off to prevent moisture intrusion; when the humidity is normal, the ventilation is partially open to balance heat dissipation and energy saving; and when the temperature is high, the air intake is fully opened and the heat is forced to be exhausted to achieve the highest heat dissipation efficiency. The three modes transition continuously, and the actuators in the high humidity mode and the high temperature mode move in opposite directions to avoid functional conflicts. Moreover, the position of slider 10 intuitively reflects the current environmental status, which is convenient for inspection and judgment.

[0044] Specifically, an observation window is provided on the top of cabinet 1, and the environmental conditions inside cabinet 1 can be determined based on the position of slider 10.

[0045] By adopting the above technical solution, maintenance personnel can quickly determine the environmental status inside the cabinet without opening the cabinet door, simply by observing the current position of the slider 10 through the observation window.

[0046] Specifically, a switch is provided at the through hole 82. When the slider 10 moves to the switch at the through hole 82, the switch is triggered to open the cover and start the exhaust fan 83.

[0047] By adopting the above technical solution, a lever can be set on the slider 10. When the lever at the left end of the slider 10 moves to the left area, it presses down the switch contact. The switch opens the cover and starts the fan through a mechanical linkage or magnetic control. After the slider 10 leaves, the switch resets, the cover closes, and the fan stops (this is existing technology and will not be described in detail here).

[0048] Specifically, a return spring 77 is provided between the slider 10 and the cabinet 1. The return spring 77 is in a free state when the slider 10 is in the middle area. When the slider 10 moves to the left or right, the return spring 77 is stretched or compressed and stores elastic potential energy. When the factor causing the speed difference disappears, the return spring 77 releases the elastic potential energy and drives the slider 10 back to the middle area.

[0049] By adopting the above scheme, when the slider 10 moves to the right, the return spring 77 is stretched and stores elastic potential energy. When the humidity returns to normal, the moisture-absorbing expansion member 91 contracts, and the speed of the first reciprocating screw 71 returns to the same level as the second reciprocating screw 72, the differential driving force disappears. At this time, the return spring 77 releases its elastic potential energy, pulling the slider 10 to the left until it returns to the middle area. At the same time, the pull rope 84 loosens, and the louver 81 returns to the half-open state under the action of the return spring 77, ensuring that the slider 10 can automatically reset after the environment returns to normal.

[0050] Specifically, a vibration motor is installed on the side of the cabinet 1 near the filter screen 4, and a sensor is installed on the slider 10. When the slider 10 moves, the sensor triggers the vibration motor to vibrate the filter screen 4.

[0051] By adopting the above technical solution, the sensor can be a mechanical limit switch with its contacts extending into the cabinet 1, or it can be a magnetic induction switch that cooperates with the permanent magnet embedded in the slider 10. When the slider 10 is in the right-side area for a long time (indicating high humidity or poor airflow due to filter 4 blockage), the lever or permanent magnet on the slider 10 triggers the sensor, which sends a start signal to the vibration motor. After being powered on, the vibration motor begins to vibrate, causing the filter 4 to oscillate at high frequency, shaking off the dust attached to the surface of the filter 4 and restoring the ventilation capacity of the filter 4.

[0052] Working principle: Initial state (normal temperature and humidity): The first impeller 5 and the second impeller 6 rotate at the same speed; the first reciprocating screw 71 and the second reciprocating screw 72 rotate at equal speeds but in opposite directions; the first toothed plate 73 and the second toothed plate 74 move at the same speed but in opposite directions; the gear 76 idles; and the slider 10 remains stationary in the middle area. At this time, the louvers 81 are half-open, the cover is closed, the exhaust fan 83 is stopped, and the cabinet relies on natural convection for basic heat dissipation.

[0053] When the ambient humidity increases: the modified wood 913 inside the moisture-absorbing expansion component 91 absorbs water and expands, pushing the inner rod 912 out. The first friction disc 92 presses against the first reciprocating screw 71, increasing its rotational resistance and causing the speed of the first reciprocating screw 71 to decrease. A speed difference is created between the first reciprocating screw 71 and the second reciprocating screw 72, resulting in different movement speeds of the toothed plates on both sides. The gear 76 and the slider 10 move to the right, and the pull rope 84 pulls the louver 81 to gradually close or reduce its opening. Simultaneously, the slider 10 moves away from the left side, the cover remains closed, and the exhaust fan 83 does not start. Finally, the slider 10 stops in the right-side area, effectively blocking the air inlet and preventing a large amount of external moisture from entering the cabinet, thus achieving moisture prevention and dehumidification.

[0054] When the ambient temperature rises: the shape memory alloy spring 93 stretches due to heat, pushing the second friction disc 94 to press against the second reciprocating screw 72, increasing its rotational resistance and causing the speed of the second reciprocating screw 72 to decrease. A speed difference is generated between the first reciprocating screw 71 and the second reciprocating screw 72, causing the slider 10 to move to the left and gradually open the louvers 81 via the pull rope 84. When the slider 10 reaches the left side area, a switch is triggered or the cover is opened directly via a mechanical push rod, and the exhaust fan 83 is activated. At this time, the air inlet is fully open, the top through-hole 82 is open, and the exhaust fan 83 forces air out, forming a smooth heat dissipation channel from the air inlet to the top, allowing heat to be quickly dissipated from inside the cabinet.

[0055] When the environment returns to normal: the moisture-absorbing expansion component 91 loses water and shrinks, the first friction disc 92 disengages from the first reciprocating screw 71, the speed of the first reciprocating screw 71 returns to normal, the slider 10 automatically moves to the left under the action of the differential transmission mechanism 7, the louver 81 returns to half-open, the cover closes, the exhaust fan 83 stops, and the cabinet returns to basic ventilation state.

[0056] In addition, when the slider 10 is in the right area for a long time (due to high humidity or filter 4 blockage), the sensor will trigger the vibration motor to intermittently oscillate the filter 4, shake off the accumulated dust, and prevent the filter 4 from being blocked and affecting the air intake.
