[0028] With such a design, when in use, the temperature state in the cabinet 1 is monitored in real time through the temperature control sensor 12. When the temperature exceeds the maximum value of the setting range of the temperature control sensor 12, the fan 5 starts to work, the heating box 7 stops working, the upper solenoid valve 10 is opened, the lower solenoid valve 11 is closed, and the hot air in the cabinet 1 is sucked in through the suction hood 3, and then the dust and foreign matter in the hot air are filtered through the filter box 6, and then the filtered hot air passes through the heating box 7, the main pipeline 8 and the end of the connecting pipe 9 with the upper solenoid valve 10 in sequence and is discharged, thereby realizing the heat dissipation process;

[0029] When the temperature is lower than the lowest value of the setting range of the temperature control sensor 12, the fan 5 starts working, the heating box 7 starts working, the upper solenoid valve 10 is closed, the lower solenoid valve 11 is opened, and the hot air in the cabinet 1 is sucked in through the suction hood 3, and then the dust and foreign matter in the hot air are filtered through the filter box 6. The filtered hot air passes through the heating box 7 for heating treatment in turn, and then the heated hot air passes through the main pipeline 8 and the end of the connecting pipe 9 with the lower solenoid valve 11 and enters the exhaust pipe 4 and is discharged, so that the interior of the cabinet 1 is heated by the circulating hot air to avoid the adverse effects of low temperature on the electrical components in the cabinet 1.

[0030] Furthermore, side air suction pipes 13 are symmetrically fixedly arranged inside the two sides of the cabinet 1, and the two side air suction pipes 13 are respectively fixedly connected to the two air guide pipes 14, and the two air guide pipes 14 are both connected to the air suction hood 3;

[0031] With this design, the two side suction pipes 13 are used to perform suction processing on the middle parts of both sides of the interior of the cabinet 1, thereby expanding the effective suction range of the fan 5.

[0032] Specifically, a filter screen panel 15 is provided inside the filter box 6, a convex plate 16 is fixedly provided on the filter screen panel 15, a toggle mechanism is fixedly provided on the filter box 6 near its air inlet, and the toggle mechanism includes a fixing frame 17, a rotating shaft 18, a fan blade 19 and an eccentric wheel 20, wherein the fixing frame 17 is fixedly provided on the inner wall of the filter box 6, the rotating shaft 18 is rotatably provided on the fixing frame 17, the fan blade 19 and the eccentric wheel 20 are both fixedly provided on the rotating shaft 18, and the eccentric wheel 20 is used in conjunction with the convex plate 16;

[0033] The filter screen panel 15 includes a middle filter screen 21, an upper flexible pad 22, a lower flexible pad 23 and a plurality of connecting springs 24, wherein the top of the middle filter screen 21 is fixedly arranged with the inner top wall of the filter box 6 through the upper flexible pad 22, the bottom of the middle filter screen 21 is fixedly arranged with the inner bottom wall of the filter box 6 through the lower flexible pad 23, and the two sides of the middle filter screen 21 are fixedly arranged with the inner walls of the two sides of the filter box 6 through symmetrically arranged connecting springs 24;

[0034] With such a design, when the air flow enters the interior of the filter box 6, the fan blades 19 on the rotating shaft 18 rotate under the action of the air flow, and the fan blades 19 drive the eccentric wheel 20 to rotate through the rotating shaft 18. The rotating eccentric wheel 20 continuously impacts the convex plate 16, and the shaking generated by the impact drives the middle filter screen 21 to vibrate, so that dust on the middle filter screen 21 falls off, avoiding dust clogging the middle filter screen 21 due to long-term use. A dust exhaust port with a cover can be set at a suitable position on the filter box 6 to facilitate regular cleaning of the dust in the filter box 6, and the air flow filtered by the middle filter screen 21 is discharged and enters the interior of the main pipeline 8.

[0035] Furthermore, multiple groups of heat dissipation holes 25 are provided on both sides of the cabinet 1, and a self-opening and closing mechanism is provided on the outer side of each group of heat dissipation holes 25; the self-opening and closing mechanism comprises a lower fixed shell 26, an upper closed shell 27 and two connecting components, wherein the lower fixed shell 26 is fixedly provided on the cabinet 1, and the lower fixed shell 26 is connected to the upper closed shell 27 through two connecting components; wherein the lower fixed shell 26 is a fully closed structure, and a side of the upper closed shell 27 close to the heat dissipation holes 25 is an open structure;

[0036] The connecting assembly includes a connecting cylinder 28, a piston 29, a connecting rod 30, a lower spring 31 and an upper spring 32, wherein the connecting cylinder 28 is fixedly disposed in the lower fixed housing 26, the connecting cylinder 28 is communicated with the lower fixed housing 26, the piston 29 is slidably disposed in the connecting cylinder 28, the piston 29 is fixedly disposed with the upper closed housing 27 through the connecting rod 30, the lower spring 31 is located between the inner bottom wall of the connecting cylinder 28 and the piston 29, and the upper spring 32 surrounds the connecting rod 30 and is located between the piston 29 and the inner top wall of the connecting cylinder 28;

[0037] With such a design, when in use, in the initial state, the upper closed shell 27 blocks the corresponding heat dissipation holes 25. When the temperature is too high, the air in the lower fixed shell 26 expands due to the heat, and under the transmission of the air gas pressure, the piston 29 slides upward inside the connecting tube 28, and the piston 29 drives the upper closed shell 27 to move through the connecting rod 30, so that the upper closed shell 27 no longer blocks the heat dissipation holes 25, so as to facilitate heat dissipation through the heat dissipation holes 25; and when the temperature is low, the air in the lower fixed shell 26 contracts due to the cold, and under the transmission of the air gas pressure, the piston 29 slides downward inside the connecting tube 28, and the piston 29 drives the upper closed shell 27 to move through the connecting rod 30, so that the upper closed shell 27 blocks the heat dissipation holes 25, so as to reduce the influence of the external temperature on the interior of the cabinet 1, and the cabinet 1 can be kept warm with the help of the hot air in the cabinet 1.

[0038] Furthermore, a left tube body 33 and a right tube body 34 are fixedly provided at both ends of the upper closed shell 27, the left tube body 33 is connected to the left main pipe 35, the right tube body 34 is connected to the right main pipe 36, a control solenoid valve 37 is fixedly provided on the left main pipe 35 and the right main pipe 36, the left main pipe 35 is connected to one of the side air intake pipes 13, and the right main pipe 36 is connected to the other side air intake pipe 13;

[0039] A slide bar 38 is fixedly disposed inside the upper closed shell 27, and a plurality of cleaning brushes 39 are also slidably disposed inside the upper closed shell 27. Adjacent cleaning brushes 39 are fixedly disposed by short rods 40. The rod hole on each cleaning brush 39 is slidably matched with the slide bar 38, and a connecting groove 41 is provided on the cleaning brush 39.

[0040] With such a design, when in use, the heat dissipation holes 25 may reduce the use effect due to the long-term accumulation of dust, and some dust will fall into the interior of the upper closed shell 27. At this time, the control solenoid valve 37 on the left main pipe 35 on one side can be opened first. At this time, when the fan 5 is working, the suction force is transmitted to the interior of the upper closed shell 27 through the top of the suction hood 3, the air guide pipe 14, the side suction pipe 13, the left main pipe 35, and the left tube body 33 in sequence. Under the action of the suction force, the cleaning brush 39 slides along the slide rod 38, so that the dust on the heat dissipation holes 25 is cleaned by the cleaning brush 39, and then the control solenoid valve 37 on the left main pipe 35 is closed, and the control solenoid valve 37 on the right main pipe 36 is opened, so that the cleaning brush 39 is moved again in the interior of the upper closed shell 27 in the same way. In this way, alternating control is used to realize the reciprocating cleaning operation process of the cleaning brush 39, and through the provided connecting groove 41, the airflow with dust can flow in the interior of the upper closed shell 27 to ensure the dust absorption effect.
