[0002] As the core control unit in the field of industrial automation, power system etc., the cleanliness of the internal environment of instrument control cabinet is crucial to the stability and reliability of equipment operation. However, in the actual application process, the dust, particulate matter and other pollutants in the air often deposit in the instrument control cabinet, leading to poor heat dissipation, circuit short circuit, poor contact and other problems, which seriously affect the normal operation and service life of the equipment.

[0003] The traditional instrument control cabinet dust removal method mainly relies on manual periodic cleaning, which not only consumes time and effort, but also cannot completely remove dust in all corners of the cabinet.
