When in use, the air supply mechanism 5 is controlled to run in the reverse direction by the power supply mechanism 8, so as to cooperate with the supporting mechanism 6 to make the dust removal mechanism 7 operate, and the dust and flocs attached to the inside of the protective mechanism 1 and the outer wall of the filter mechanism 9 are discharged through the cooperation of the dust removal mechanism 7 and the air supply mechanism 5, which effectively avoids the problem that dust enters the inside of the hair dryer and accumulates and cannot be cleaned during use, resulting in motor overheating and power reduction.

[0029] As an implementation method in this embodiment, Figure 7As shown, the air supply mechanism 5 includes a positioning sleeve 501, and the positioning sleeve 501 is fixedly arranged inside the lower supporting sleeve 106.

[0033] As an implementation method in this embodiment, Fig.10 As shown, the filter mechanism 9 includes a filter cover 901, the filter mechanism 9 is fixedly connected to the lower end of the handle 105, the lower end of the filter mechanism 9 is fixedly connected to a lower fixed sleeve 902, the lower fixed sleeve 902 is internally fixed with a lower one-way bearing 903, the inner ring of the lower one-way bearing 903 is fixedly connected to the other end of the transmission rod 604, the outer layer of the filter cover 901 is arranged in a ring and a plurality of filter holes 904 are provided, the lower one-way bearing 903 in the lower fixed sleeve 902 can effectively constrain the transmission rod 604 to follow the synchronous rotation when the turbine blade 503 rotates forward, and the transmission rod 604 can only rotate in one direction through the cooperation of the upper one-way bearing 505 and the lower one-way bearing 903, and the plurality of filter holes 904 provided on the filter cover 901 can effectively prevent larger foreign matter from entering the protection mechanism 1.

[0034] As an implementation method in this embodiment, Figure 2 As shown, the extension mechanism 2 includes a docking sleeve 201, which is sleeved on the outer side of the air nozzle 102 near one end, and the docking sleeve 201 and the air nozzle 102 are detachably connected. The output end of the docking sleeve 201 is fixedly connected to the extension tube 202, and the output end of the extension tube 202 is fixedly connected to the air outlet shell 203, and one side of the air outlet shell 203 is fixedly connected to a cover plate 204, and one side of the cover plate 204 is arranged in a rectangular shape with a plurality of air outlet holes 205, and one side of the cover plate 204 is fixedly connected to a plurality of comb teeth 206 arranged in a rectangular shape. When in use, the docking sleeve 201 is sleeved and connected to the air nozzle 102, and the heating device 3 and the air supply mechanism 5 are started. After completion, pick up the air outlet shell 203 and use the plurality of comb teeth 206 on the cover plate 204 to comb the hair, so that the hair is evenly dried, effectively ensuring the smoothness of the hair.

[0035] Working principle: When in use, the power switch 801 can be used to start and stop and control the forward and reverse rotation of the ducted motor 502, and the heating switch 802 can be used to start and stop the heating device 3. After the ducted motor 502 is started, the turbine blades 503 are driven to rotate through the ducted motor 502 and the ducted motor 502. The ducted motor 502 cooperates with the turbine blades 503 to effectively improve the transmission of air volume. The positioning sleeve 501 can effectively fix the ducted motor 502 inside the lower support sleeve 106, and the docking sleeve 201 is connected to the air nozzle 102. The heating device 3 and the air supply mechanism 5 are started. After completion, pick up the air outlet shell 203 and use the multiple comb teeth 206 on the cover plate 204 to comb the hair, so that the hair is evenly dried, which effectively ensures the smoothness of the hair. When the ducted motor 502 rotates in the opposite direction, it will drive the turbine blades 503 to rotate. At the same time, the turbine blades 503 will drive the upper fixed sleeve 504 fixed at one end to rotate. Because of the constraint of the upper one-way bearing 505 installed in the upper fixed sleeve 504, when the turbine blades 503 rotate, the transmission rod 604 will also be driven to rotate. When the transmission rod 604 rotates, it will synchronously drive the dust removal mechanism 7 to rotate. When the transmission rod 604 rotates, it will also drive the sleeve 701 fixedly connected with multiple connecting seats 702 to rotate, so that the multiple brush heads 703 on the connecting seats 702 follow the rotation and remove the flocs contained in the filter mechanism 9, effectively preventing dust and flocs from entering the protection mechanism 1, thereby causing the circuit inside the protection mechanism 1 to age due to heat.

[0036] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
