[0025] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0026] This embodiment includes an equipment box 1, a dehumidification mechanism 2, and a wiping assembly 3.

[0027] The dehumidification mechanism 2 includes an assembly box 21, an exhaust fan 22, an air duct 23, a heating element 24, a sealing ring 25, and a ventilation fan 26.

[0028] Ventilation openings 11 are provided on both sides and the top of the equipment box 1. Ventilation fans 26 are installed on the outer side of the ventilation openings 11 on both sides of the equipment box 1. The ventilation fans 26 are mainly used to accelerate the ventilation effect inside the equipment box 1. When the humidity of the surrounding air is at a normal level, the ventilation fans 26 can accelerate the ventilation and heat dissipation of the circuit components inside the equipment box 1.

[0029] Assembly box 21 is fixedly mounted on the upper part of equipment box 1, and a sealing ring 25 is provided between assembly box 21 and equipment box 1 for sealing. Exhaust fan 22 is installed inside assembly box 21. Ventilation opening 11 at the top of equipment box 1 serves as air inlet for exhaust fan 22.

[0030] The air duct 23 is fixedly installed at the lower end of the assembly box 21. Two sets of air ducts 23 are provided, and the two sets are symmetrically arranged. An assembly slot 12 for inserting the air duct 23 is provided at the upper end of the equipment box 1. The air duct 23 is inserted into the assembly slot 12, thus fixing the air duct 23 at the upper end of the equipment box 1. An air outlet is provided at the bottom of the air duct 23, which communicates with the interior of the equipment box 1, thus achieving communication between the air duct 23 and the interior of the equipment box 1. The heating element 24 is installed inside the air duct 23.

[0031] The wiping assembly 3 is located at the upper part inside the equipment box 1, and includes a mounting bracket 31, a track plate 32, a slider 33, an absorbent cloth 34, a fixing bracket 35, a threaded rod 37, a servo motor 38, and a slide bar 39.

[0032] Mounting brackets 31 are fixedly installed inside the equipment box 1 by bolts. There are two sets of mounting brackets 31, symmetrically distributed on the left and right. Track plates 32 are fixed on the two sets of mounting brackets 31, thus the track plates 32 are fixed inside the equipment box 1 by the mounting brackets 31. There are two sets of track plates 32, symmetrically distributed side by side. The inner side of each track plate 32 is provided with a sliding groove for the slider 33 to slide. The sliding rod 39 is fixedly installed in the sliding groove, and the slider 33 is slidably installed on the sliding rod 39. Thus, the slider 33 is slidably installed on the track plate 32. When the slider 33 moves axially relative to the track plate 32, the track plate 32 acts as a limit for the slider 33.

[0033] The absorbent cloth 34 is detachably installed on the upper end of the slider 33. The absorbent cloth 34 can be made of fiber cloth or non-woven fabric, both of which have good water absorption. The absorbent cloth 34 is in contact with the upper end of the inner wall of the equipment box 1. When hot air is discharged into the equipment box 1, small water droplets appear on the upper end of the inner wall of the equipment box 1. The absorbent cloth 34 moves along the path of the threaded rod 37 to wipe the water droplets on the upper end of the inner wall of the equipment box 1. After one round of wiping, the internal temperature of the equipment box 1 rises to the normal temperature, thus completing the dehumidification and moisture removal work. The lower end of the slider 33 is symmetrically provided with fixing frames 35. A secondary cloth block 36 is slidably connected between the two sets of fixing frames 35. The secondary cloth block 36 is located below the absorbent cloth 34.

[0034] A waterproof box is installed on the side of the equipment housing 1 closest to the ventilation fan 26. The servo motor 38 is housed inside the waterproof box, thus the servo motor 38 is installed inside the equipment housing 1. The output end of the servo motor 38 is fixedly connected to one end of the threaded rod 37. The threaded rod 37 is threadedly connected to the slider 33. Servo motor 38 drives threaded rod 37 to rotate, causing slider 33 to move axially along threaded rod 37. The fixed frame 35 installed at the lower end of slider 33 is slidably installed with auxiliary cloth block 36. The length of auxiliary cloth block 36 is greater than the length of absorbent cloth block 34. When absorbent cloth block 34 wipes water droplets on the upper end of the inner wall of equipment box 1, the outward force on the water droplets exceeds its surface tension and adhesion force with the inner wall of equipment box 1. Therefore, some water droplets near absorbent cloth block 34 may drip, which can be caught by auxiliary cloth block 36 to prevent dripping onto circuit components. When absorbent cloth block 34 moves to the edge of equipment box 1, auxiliary cloth block 36 is pushed away from the inner wall of equipment box 1, realizing the work of catching water droplets during the round trip. The air ducts 23 are located on both sides of the upper end of the equipment box 1. Therefore, when the slider 33 is stopped at one end of the inner wall of the equipment box 1, the hot air generated by the exhaust fan 22 through the heating element 24 will blow directly onto the absorbent cloth 34 to speed up the drying of the absorbent cloth 34. Meanwhile, the air ducts 23 at the end far from the absorbent cloth 34 will normally exhaust hot air into the interior of the equipment box 1.

[0035] To further achieve intelligent operation, this invention may also include a temperature and humidity sensor and an intelligent controller. The temperature and humidity sensor is connected to the corresponding interface of the intelligent controller via a signal line, transmitting real-time temperature and humidity data inside the equipment box 1. The heating element 24 is connected to the intelligent controller via a power line and a control line. Based on the data from the temperature and humidity sensor, the intelligent controller controls the switching and power output of the heating element 24. The exhaust fan 22 and the ventilation fan 26 are also connected to the intelligent controller via power lines and control lines. The intelligent controller adjusts the fan speed as needed to optimize airflow and dehumidification. Preset threshold values ​​can be set for the temperature and humidity sensor.

[0036] In use, an assembly box 21 is installed on the upper part of the equipment box 1. A ventilation fan 26 and a servo motor 38 are respectively installed on one side of the outside of the equipment box 1. The servo motor 38 is covered by a waterproof box. When the air humidity inside the assembly box 21 exceeds the preset threshold of the temperature and humidity sensor, the exhaust fan 22 and the heating element 24 are started by the intelligent controller to generate hot air inside the equipment box 1 and heat the inside of the equipment box 1 to achieve dehumidification. At the same time, the servo motor 38 is started, and the slider 33 moves back and forth along the path of the threaded rod 37. The absorbent cloth 34 wipes the upper part of the inner wall of the equipment box 1 to prevent the formation of water droplets in advance. If there are already small water droplets, the absorbent cloth 34 can also wipe and absorb the water droplets. After the internal temperature of the equipment box 1 reaches the preset value, water droplets no longer form on the upper part of the inner wall of the equipment box 1. The slider 33 is stopped at one end inside the equipment box 1 and dried by hot air for the next use.

[0037] Furthermore, it should be noted that the specific embodiments described in this specification may differ in the shape and name of their components. The above description is merely illustrative of the structure of this utility model. All equivalent or simple variations made based on the structure, features, and principles described in this utility model patent concept are included within the protection scope of this utility model patent.
