[0048] The connecting component 103 is connected to the space between the control cabinet body 101 and the inner frame 106 through the air inlet 105 .

[0049] In the above structure, the top of the connecting component 103 is connected to the air outlet 304 of the fan device 3. By connecting the top of the connecting component 103 and the air outlet 304 of the fan device 3, when the fan device 3 is in operation, the outside air can be transmitted to the space between the control cabinet body 101 and the inner frame 106 through the fan device 3, and the gas is buffered by the buffer filter material 107 to achieve flow, thereby avoiding the problem that the gas with too fast flow rate collides with the structure of the control cabinet component 1, causing abnormal noise or damage to the equipment. On the other hand, while reducing the gas flow rate by the buffer filter material 107, , foreign matter in the gas can be filtered through the buffer filter material 107, thereby reducing the content of foreign matter or dust in the control cabinet component 1, and the gas is buffered by the buffer filter material 107 and then discharged into the inner cavity of the inner layer frame 106 through the through hole 104, so that the gas neutralizes the heat of the electronic components 5 and is discharged from the exhaust port 102, thereby achieving cooling of the electronic components 5. When the gas buffered by the buffer filter material 107 comes into contact with the electronic components 5, it can avoid the problem of gas with too fast flow rate impacting the structure of the electronic components 5, causing damage to the electronic components 5.

[0050] In a preferred embodiment, the fan device 3 includes a left fan housing portion 301 and a right fan housing portion 303, and air outlets 304 are provided on opposite surfaces of the left fan housing portion 301 and the right fan housing portion 303;

[0051] A partition 302 is fixedly mounted between the left portion 301 and the right portion 303 of the fan housing. A motor 306 is fixedly mounted on the inner wall of the left portion 301 of the fan housing. An impeller component 305 is fixedly mounted on the end of the output shaft of the motor 306.

[0052] An axial hole 1 307 is provided at a position relative to the partition 302 and the motor 306 , and an axial hole 2 308 is provided at a position relative to the right portion 303 of the fan housing and the motor 306 ;

[0053] A guide rail component 309 is fixedly mounted on the inner wall of the second axial hole 308 , and a cleaning mechanism 310 is slidably sleeved on the outer edge of the guide rail component 309 .

[0054] In the above structure, the impeller component 305 is driven to rotate by the motor 306, and the axial direction of the impeller component 305 is connected to the outside world through the axial hole 2 308 and the axial hole 1 307, so that the impeller component 305 in the running state inhales the gas. The air is subjected to the centrifugal force inside the impeller component 305, and the blades of the impeller component 305 do work on the air, so that the air obtains kinetic energy and is thrown to the outer edge of the impeller component 305, and the speed and pressure increase. At this time, the air enters the diffuser composed of the left part 301 of the fan housing, the partition 302 and the right part 303 of the fan housing. The flow channel gradually expands, the air flow rate decreases, and part of the kinetic energy is converted into pressure energy, forming a higher static pressure, so that the high-pressure gas is discharged through the air outlet 304.

[0055] In a preferred embodiment, the impeller component 305 includes a main impeller 3051 and an auxiliary impeller 3052. A filter plate 3053 is fixedly installed between the main impeller 3051 and the auxiliary impeller 3052. The outer wall of the filter plate 3053 is provided with a plurality of filter holes 3054. The plurality of filter holes 3054 are located within a circle formed by the plurality of blades in the main impeller 3051.

[0056] The filter plate 3053 and the partition plate 302 are located on the same plane.

[0057] In the above structure, when the impeller component 305 is running, air is sucked into the center of the impeller component 305, and by setting the filter plate 3053, the air is filtered through the filter plate 3053. As the impeller component 305 rotates, foreign matter attached to the surface of the filter plate 3053 is thrown toward the outer edge of the impeller component 305 by the action of centrifugal force. The filter plate 3053 and the partition 302 are located in the same plane, and the space formed by the left part 301 of the fan housing and the right part 303 of the fan housing is isolated by the partition 302, thereby forming a flattened diffuser between the partition 302 and the right part 303 of the fan housing, and the foreign matter thrown out of the impeller component 305 is discharged through the air outlet 304 under the dual action of centrifugal force and high-pressure gas.

[0058] In a preferred embodiment: the guide rail component 309 includes a guide rail body 3091 and a guide rail end 3092, the guide rail end 3092 is located on the side close to the air outlet 304, the outer wall of the guide rail end 3092 is provided with an engagement groove 3093, and the outer wall of the guide rail body 3091 and the guide rail end 3092 away from the engagement groove 3093 is provided with a sliding groove 3094.

[0059] In a preferred embodiment: the cleaning mechanism 310 includes a sliding component 3101, a notch 3102 is provided on the outer wall of the sliding component 3101 near the impeller component 305, a magnetic member 3104 is slidably sleeved on the inner wall of the notch 3102, a telescopic mechanism 3103 is embedded in the inner wall of the sliding component 3101, the telescopic end of the telescopic mechanism 3103 is connected to the magnetic member 3104, a sliding groove 3105 is provided on the side of the sliding component 3101 near the guide rail component 309, a clockwork mechanism 3110 is embedded on the sliding component 3101, and the end of the sliding component 3101 away from the notch 3102 is rotatably connected to a movable plate 3106, both sides of the movable plate 3106 are softly connected with soft connectors 3107, the ends of the soft connector 3107 are softly connected to both sides of the sliding component 3101, and the outer wall of the movable plate 3106 is respectively inlaid with a first magnetic element 3108 and a second magnetic element 3109;

[0060] The side of the first magnetic element 3108 close to the sliding assembly 3101 is the S pole, the side of the second magnetic element 3109 close to the sliding assembly 3101 is the N pole, and the side of the magnetic member 3104 close to the movable plate 3106 is the S pole.

[0061] The foreign matter thrown out of the impeller component 305 is separated from the filter plate 3053 by the centrifugal force, but the foreign matter may be adhered to the inner edge of the right part 303 of the fan housing. Therefore, when it is necessary to clean the inner edge of the right part 303 of the fan housing, the controller controls the telescopic mechanism 3103 to make the telescopic mechanism 3103 push the magnetic piece 3104 and the first magnetic element 3108 to correspond to each other, and utilizes the magnetic principle of like-sex repulsion between the magnetic piece 3104 and the first magnetic element 3108 to make the first magnetic element 3108 drive the movable plate 3106 and the soft connector 3107 to expand, and the movable plate 3106 and the soft connector 3107 are opened. When 3107 is in the expanded state, the air is subjected to the centrifugal force inside the impeller component 305, and the blades of the impeller component 305 do work on the air, so that the air gains kinetic energy and is thrown toward the outer edge of the impeller component 305, and the speed and pressure increase. At this time, the air enters the diffuser composed of the partition 302 and the right part 303 of the fan housing and is discharged from the air outlet 304. At the same time, the air exerts pressure on the sliding assembly 3101, the movable plate 3106 and the soft connector 3107, thereby driving the cleaning mechanism 310 to move along the guide rail component 309, and then the cleaning mechanism 310 scrapes and cleans the foreign matter on the inner edge of the right part 303 of the fan housing.

[0062] In a preferred embodiment, the clockwork mechanism 3110 includes a barrel with teeth on its outer edge, a spiral spring located in an inner cavity of the barrel, and a barrel shaft connected to the central end of the spiral spring.

[0063] The bar shaft and the sliding assembly 3101 are fixedly assembled, and the tooth grooves provided on the outer edge of the barrel wheel are adapted to the engagement grooves 3093 .

[0064] In the above structure, by providing the sliding groove 3094, when the cleaning mechanism 310 is located in front of the guide rail component 309 and slides, the outer edge of the barrel wheel in the clockwork mechanism 3110 will not rub against the outer edge of the guide rail body 3091, thereby ensuring the smooth movement of the cleaning mechanism 310 along the guide rail component 309, and by providing the engagement groove 3093, air is used to apply pressure to the sliding component 3101, the movable plate 3106 and the soft connector 3107, thereby driving the cleaning mechanism 310 to move along the guide rail component 309, and the tooth groove provided on the outer edge of the barrel wheel engages with the engagement groove 3093, so that the cleaning mechanism 310 is located in the front of the guide rail component 309. When the engaging groove 3093 moves, the mainspring is wound, and the controller controls the telescopic mechanism 3103 to push the magnetic piece 3104 and the second magnetic element 3109 to correspond to each other. By utilizing the magnetic principle of opposite poles attracting each other, the first magnetic element 3108 drives the movable plate 3106 and the soft connecting piece 3107 to merge, so that the force exerted by the air on the sliding component 3101, the movable plate 3106 and the soft connecting piece 3107 is smaller than the energy released by the mainspring and the force of the barrel wheel, so that the sliding component 3101 moves back to its position along the guide rail component 309.

[0065] Working principle:

[0066] When fan unit 3 is started, motor 306 drives impeller assembly 305 to rotate at high speed via its output shaft. Air is drawn into the center of impeller assembly 305 through axial hole 1 307 and axial hole 2 308. The blades of main impeller 3051 and auxiliary impeller 3052 work on the air, generating centrifugal force that throws the air toward the outer edges of the impellers, increasing its velocity and pressure. High-pressure air enters the diffuser space formed by the left portion of the fan housing 301, partition 302, and right portion of the fan housing 303. The diffuser flow path gradually expands, the air velocity decreases, and some of the kinetic energy is converted into static pressure energy, forming high-pressure gas that is discharged through outlet 304.

[0067] High-pressure air flows from the air outlet 304 through the connecting component 103 into the space between the control cabinet body 101 and the inner frame 106. The connecting component 103 communicates with this space through the air inlet 105, which in turn communicates with the inner cavity of the inner frame 106 through the through hole 104. When the air passes through the buffer filter material 107, the flow rate is significantly slowed, preventing the high-speed airflow from directly impacting the control cabinet body 101 or the inner frame 106, thereby reducing abnormal noise or structural damage to the equipment.

[0068] The buffer filter material 107 simultaneously filters dust and particulate matter in the air, reducing the foreign matter content inside the control cabinet component 1 and keeping the interior clean. The air decelerated by the buffer filter material 107 enters the inner cavity of the inner frame 106 through the through hole 104, comes into contact with the electronic components 5, and absorbs the heat generated during their operation. Because the air flow rate has been reduced by the buffer filter material 107, the air flow contacts the electronic components 5 gently, avoiding vibration or damage caused by the impact of high-speed air flow. The heat-carrying air is discharged through the exhaust port 102 on the bottom side of the control cabinet component 1, achieving continuous cooling of the electronic components 5 and maintaining a stable temperature inside the control cabinet.

[0069] When air is drawn into the center of the impeller, it undergoes preliminary filtration through filter plate 3053, where dust and particulate matter adhere to the surface. As impeller assembly 305 rotates at high speed, foreign matter adhering to filter plate 3053 is flung toward the outer edge of the impeller by centrifugal force. Partition plate 302 and the right portion of the fan housing 303 lie on the same plane, forming a flattened diffuser structure. The flung foreign matter, driven by the combined effects of centrifugal force and high-pressure air, is discharged through air outlet 304, preventing it from accumulating within impeller assembly 305 or the right portion of the fan housing 303.

[0070] The controller drives the telescopic mechanism 3103, pushing the magnetic member 3104 so that its south pole faces the south pole of the first magnetic element 3108. Utilizing the principle of like magnets repelling like charges, the movable plate 3106 and flexible connector 3107 expand. High-pressure air exerts pressure on the sliding assembly 3101, movable plate 3106, and flexible connector 3107, driving the cleaning mechanism 310 to slide along the sliding groove 3094 of the guide rail 309. The sliding groove 3094 reduces friction and ensures smooth sliding. As the cleaning mechanism 310 slides, it scrapes away foreign matter adhering to the inner wall of the right portion 303 of the fan housing, keeping the interior of the diffuser clean.

[0071] The guide rail end 3092 is provided with an engagement groove 3093, which engages with the teeth of the barrel of the clockwork mechanism 3110 within the sliding assembly 3101. When air pressure pushes the cleaning mechanism 310 to slide, the barrel rotates, storing energy for winding the mainspring. After cleaning is complete, the controller activates the telescopic mechanism 3103, aligning the south pole of the magnetic element 3104 with the north pole of the second magnetic element 3109. Utilizing the principle of opposite magnets attracting each other, the movable plate 3106 and the flexible connector 3107 merge, restoring their compact state. After this merger, the air pressure on the sliding assembly 3101, movable plate 3106, and flexible connector 3107 decreases, falling below the energy stored in the clockwork mechanism 3110. The mainspring releases energy, driving the barrel, which, through the engagement groove 3093, drives the sliding assembly 3101 back to its initial position along the guide rail component 309.
