Zusammenfassung:	The utility model discloses a frequency converter with a dustproof function, which relates to the technical field of frequency converters and comprises a base, a frequency converter body is fixedly connected to the top end of the base, two limiting assemblies are arranged on one side of the frequency converter body, four through grooves are formed in the other side of the frequency converter body, and clamping blocks are connected to the inner sides of the four through grooves in a clamping mode. The dustproof device has the advantages that the rotating rod is attached to the interior of the opening so that the rotating rod can be preliminarily limited, the dustproof blades can be conveniently placed into the shell, the other nine ventilation holes are shielded for dust prevention, the rubber layer is arranged on the outer side of the rotating rod, and therefore the dustproof device is convenient to use, and the service life of the dustproof device is prolonged. And the outer side of the rotating rod is conve
