[0029] The specific usage and function of this embodiment are as follows:

[0030] When using this dustproof hair dryer, dustproof covers 2 are snapped onto the front and rear ends of the hair dryer body 1, and the two dustproof covers 2 are connected to each other by two elastic reinforcing bars 201. The elastic reinforcing bars 201 improve the stability of the dustproof covers 2 installed at the front and rear ends of the hair dryer body 1. Thus, when the hair dryer is not in use, the dustproof covers 2 prevent dust from entering the hair dryer body 1 during storage, thereby reducing the aging of the heating element 103 and the high-speed fan wheel 104. By inserting the built-in filter cartridge 4 into the connecting sleeve 3, the connecting insert 402 of the built-in filter cartridge 4 is inserted into the connecting insert hole 302 of the connecting sleeve 3. At this time, the two locking wedges 5 are locked on the front outer wall of the connecting sleeve 3 under the action of the support spring 6, and the threaded fan blade 401 on the outside of the built-in filter cartridge 4 and the connecting sleeve can pass through. The inner walls of the three sides form an air duct, and the air drawn in by the blower body 1 is filtered by the threaded fan blades 401 to prevent dust from entering the blower body 1. When the control finger 503 of the two locking wedges 5 is pressed and the locking wedges 5 are brought closer together, the built-in filter cartridge 4 can be removed from the connecting sleeve 3 to clean the dust blocked on the threaded fan blades 401 on the outside of the built-in filter cartridge 4, which improves the convenience of dust cleaning. By connecting the fixing thread 303 of the connecting sleeve 3 with the connecting thread 102 of the inner side wall of the rear end of the blower body 1, the disassembly and assembly of the connecting sleeve 3 and the blower body 1 can be realized. The barrier net 301 set at the front end of the connecting sleeve 3 can cooperate with the threaded fan blades 401 on the outside of the built-in filter cartridge 4 to further symmetrically draw in air for dust removal.
