[0002] An electrical installation cabinet refers to a protective cabinet used to install and place electrical equipment, which plays a role in protecting electrical equipment. Since the electrical equipment in the electrical installation cabinet will generate a lot of heat when working, in order to facilitate heat dissipation, the electrical installation cabinet usually has more ventilation holes. However, more holes will easily lead to more dust entering the electrical installation cabinet, which will cause pollution to the electrical equipment inside. Therefore, it is necessary to set up a dustproof mechanism in the electrical installation cabinet to clean the dust.

[0003] When using an electrical installation cabinet, a filter plate is generally installed at the vent. The function of this filter plate is mainly to prevent dust from entering the cabinet. However, the dust-proof effect of this filter plate is limited. In addition, the electrical equipment needs to be placed inside the filter frame during use. When cleaning the filter frame, the electrical equipment and the filter frame need to be taken out in turn. After cleaning, they need to be placed back together. This method of operation is too complicated and requires constant installation and disassembly of the electrical equipment, which can easily cause damage to the electrical equipment.
