[0018] When the present invention is in use, in the cooling component, when the device is in use, the control board is started, driving the output shaft to run, and the output shaft will drive the cold air guide fan to run. At the same time, the refrigeration box runs to generate cold air, and the cold air generated by the refrigeration box is transmitted through the cold transfer plate. When the cold air guide fan is running, it will blow the cold air transmitted by the cold transfer plate in a directional manner, and finally enter the device through the cold insulation net box, thereby achieving an external cooling effect on the device, thereby reducing damage to the device in a high temperature environment. When the cold air enters the device through the cold insulation net box, the cold air generated by the cold air guide fan The generated wind force will cause the elastic arc plate to undergo elastic deformation. The angle formed by the deformation of the elastic arc plate will change the wind direction of the cold air entering the device at various angles, thereby being able to cool down and protect the device more evenly. At the same time, the wind force generated by the cold air guide fan will continuously change the wind direction through the elastic arc plate, thereby driving the oblique fan plate to rotate. The oblique fan plate will then drive the oblique rotating shaft to rotate along the surface of the oblique plate. The oblique rotating shaft will change the wind direction of the cold air, allowing it to enter the running device more accurately, thereby protecting the device.

[0019] When the present invention is in use, in the dust removal component, the control board will control the operation of the transmission shaft, and the transmission shaft will drive the dust removal fan to operate. At the same time, the anti-electricity box will start, and the anti-electricity box will absorb the dust in the device through the electrostatic effect. At the same time, the wind force generated by the operation of the dust removal fan will cause the dust absorbed by the anti-electricity box to pass out through the dust isolation plate. When the dust is reduced, the heat insulation effect of the charger during operation will be reduced, thereby reducing the damage to the device caused by high temperature. At the same time, the control board will also control the operation of the threaded rotating rod, and the threaded rotating rod will drive the inner thread to rotate. When the grooved rod runs, the internal threaded rod will drive the dust sweeping plate to run along the surface of the charger, so as to clean the dust on the surface of the charger in time, thereby enhancing the dust removal effect in the device; at the same time, when the internal threaded rod runs, it will drive the horizontal plate to run, the horizontal plate will drive the vertical shaft to run, the vertical shaft will drive the dust sweeping tooth column to run, and through the meshing connection with the rack surface, it will drive the dust sweeping tooth column to rotate, and the dust sweeping tooth column will drive the vertical shaft to rotate along the inner wall of the horizontal plate. When the dust sweeping tooth column runs, it will clean the inner wall of the dust shielding plate to prevent damage to the device caused by dust clogging.

[0020] When the present invention is in use, the control board in the heat dissipation component controls the operation of the auxiliary shaft. When the auxiliary shaft is running, it will drive the heat dissipation fan to run. When the heat dissipation fan is running, the heat generated in the device will be dissipated through the heat dissipation mesh box. At the same time, the heat generated by the device is directed through the heat-conducting column. The heat is finally transferred to the heat dissipation plate, and can be dissipated in the direction of the heat dissipation fan through the heat dissipation plate, so that the device can better adapt to high temperature environments. At the same time, when the dust sweeping plate is running, it will drive the card plate on the surface to run, and the card plate will drive the cross bar to run. When the cross bar is running, it will drive the cross axis at the other end to run, and the cross axis will drive the spring fan to run. When the spring fan is running, the heat generated by the device can be better assisted in heat transfer through its own elastic force, thereby better protecting the device.

When the cold air enters the device through the cold insulation net box 24, the cold air guide fan 22 generates The generated wind force will cause the elastic arc plate 30 to undergo elastic deformation. The angle formed by the deformation of the elastic arc plate 30 will change the wind direction of the cold air entering the device at various angles, thereby being able to cool down and protect the device more evenly. At the same time, due to the wind force generated by the cold air guide fan 22, the wind direction is continuously changed through the elastic arc plate 30, thereby driving the oblique fan plate 27 to rotate. The oblique fan plate 27 will drive the oblique rotating shaft 26 to rotate along the surface of the oblique plate 25, and the oblique rotating shaft 26 will change the wind direction of the cold air, allowing it to enter the running device more accurately, thereby protecting the device. At this time, in the dust removal component 2, the control board 4 will control the operation of the transmission shaft 41, and the transmission shaft 41 will drive the dust removal fan 42 to operate. At the same time, the anti-electricity box 7 will start, and the anti-electricity box 7 will absorb the dust in the device through the electrostatic effect. At the same time, the wind force generated by the operation of the dust removal fan 42 will cause the dust absorbed by the anti-electricity box 7 to pass through the dust isolation plate 44. When the dust is reduced, the heat insulation effect of the charger 5 during operation will be reduced, thereby reducing the damage to the device caused by high temperature. At the same time, the control board 4 will also control the operation of the threaded rotating rod 45. The threaded rotating rod 45 is connected through the thread on the surface, which will drive the internal threaded rod 46 to operate. The internal threaded rod 46 will drive the dust-sweeping plate 48 to move along the surface of the charger 5, so as to clean the dust on the surface of the charger 5 in time, thereby enhancing the dust removal effect in the device. At the same time, when the internal threaded rod 46 is running, it will drive the cross plate 47 to run, the cross plate 47 will drive the vertical shaft 49 to run, the vertical shaft 49 will drive the dust-sweeping tooth column 50 to run, and through the meshing connection with the surface of the rack 51, the dust-sweeping tooth column 50 will be driven to rotate, and the dust-sweeping tooth column 50 will drive the vertical shaft 49 to rotate along the inner wall of the cross plate 47. When the dust-sweeping tooth column 50 is running, the inner wall of the dust-shielding plate 44 will be cleaned to prevent damage to the device caused by dust clogging.At this time, in the heat dissipation component 3, the control board 4 controls the operation of the auxiliary shaft 61. When the auxiliary shaft 61 is running, it will drive the cooling fan 62 to run. When the cooling fan 62 is running, the heat generated in the device will be dissipated through the heat dissipation mesh box 63. At the same time, the heat generated by the device is directed through the heat conducting column 64. The heat is finally transferred to the heat dissipation plate 65, and can be dissipated to the direction of the cooling fan 62 through the heat dissipation plate 65, so that the device can better adapt to the high temperature environment. At the same time, when the dust sweeping plate 48 is running, it will drive the card plate 67 on the surface to run, and the card plate 67 will drive the cross bar 68 to run. When the cross bar 68 is running, it will drive the horizontal axis 69 at the other end to run, and the horizontal axis 69 will drive the spring fan 70 to run. When the spring fan 70 is running, through its own elastic force, the heat generated by the device can be better assisted in heat transfer, and the device can be better protected.
