[0002] Construction project archives are engineering terms, referring to various forms of historical records such as texts, charts, audio-visual materials, etc. that are directly formed during engineering construction activities and have the value of being archived and preserved. With the rapid development of China's social economy, the urban construction speed has been continuously accelerating, and the number of engineering construction projects has been increasing day by day; the traditional paper-based file management method can no longer meet the requirements of modern urban construction for the efficiency, convenience, and security of file management work.

[0003] Chinese Patent with the publication number CN219680088U discloses a construction project archive management cabinet, including a box body, a rotating door, and a handle. Rotating doors are rotatably provided on both the left and right sides of the front side of the box body, and a handle is connected to the rotating door. By starting the electric fan, the wind generated by the operation of the electric fan can drive the smell of the insecticide to move upward and be discharged through the air outlet pipe, thereby achieving the effect of killing insects on the files. The humidity sensor can automatically detect the humidity.
