[0005] Preferably, there is also an air outlet, which is located on the opposite side of the air inlet.

[0006] Preferably, the table top is a horizontal plane or an inclined plane.

[0007] Preferably, the side portion of the air inlet cover is axially overlapped with the motor inner cavity outer shell, and an air layer is provided between the side portion of the air inlet cover and the motor inner cavity outer shell.

[0008] Preferably, the air inlet cover and the outer shell are integrally formed.

[0009] Preferably, the air inlet cover is an accessory of the hair dryer, and is fixed to the hair dryer housing by means of fastening screws, a snap-fit ​​structure or magnetic attraction.

[0010] Preferably, a heating structure is further included, and the heating structure is located downstream of the motor in the wind direction.

[0011] Preferably, the hair dryer further comprises a hair dryer handle, wherein the hair dryer handle has heat dissipation holes.

[0012] Preferably, the cross section of the air inlet cover is a polygon, and the corners of the polygonal structure are arc chamfers.

[0013] Preferably, the cross section of the air inlet cover is circular.

[0014] Compared with the prior art, the beneficial effects obtained by the utility model are:

[0015] The utility model discloses a hair dryer with a novel noise-reducing air inlet structure, comprising an air inlet hood, a motor, and a casing. The air inlet hood is arranged around the cavity casing where the motor is located, and the air inlet hood has an end portion and a side portion, and a table with air inlet holes is arranged at the connection between the side portion and the cavity casing where the motor is located.
