Description

Technical Field

[0001] This utility model relates to the field of electrical engineering technology, specifically to an electrical box for electrical engineering automation. Background Technology

[0002] An electrical box is a device used to install circuits and electronic components, which are then mounted on a mounting plate inside the box using screws. Electrical boxes typically use louvers and exhaust fans for heat dissipation. To prevent dust from the outside air from entering the box and covering the surfaces of the components—as excessive dust can cause short circuits, damage equipment, and even lead to fires—dust filters are usually installed on the louvers to filter the air entering the electrical box.

[0003] However, in order to ensure the ventilation efficiency of the electrical box, the pore size of the dust filter should not be too small. Therefore, it cannot filter out dust particles with small diameters in the air. In addition, when the staff maintains the electrical box, they need to open the electrical box, which will allow outside air to enter the electrical box directly. This will cause the surface of the electrical components in the electrical box to remain covered with dust after long-term use, affecting the normal operation of the electrical components. Utility Model Content

[0004] The purpose of this utility model is to provide an electrical box for electrical engineering automation, which can clean the dust adhering to the surface of electrical components in the electrical box, keep the environment inside the electrical box clean, and prevent damage to the electrical components.
