Specifically, the casing 10 may have a substantially circular truncated cone shape, and the cross-sectional area of the casing 10 gradually increases from the air inlet end 10a to the air outlet end 10 b. Thus, the airflow blown out from the fan body 300 can flow to the air outlet end 10b along the extending direction of the inner wall of the casing 10, so that the air outlet range is enlarged; the circular truncated cone shaped housing 10 can make the air flow velocity at each position of the inner circumference of the housing 10 the same, so that the air flow blown by the hair dryer 1000 at each position is more uniform to further improve the blowing effect. Additionally, to reduce the mass of the hairdryer 1000 so that it is convenient for a user to hold it in his or her hand. The material of the housing 10 may be plastic material, for example: ABS, POM, PS, PMMA, PC, PET, etc. The air inlet end 10a is mainly used for communicating with the blower body 300, and specifically, a through hole communicated with the blower body 300 is formed to communicate the air inlet end and the blower body. Wherein, air inlet end 10a and fan body 300 can be through screw, buckle or magnetism fixed to make diffuser 100 and fan body 300 both when one of them takes place to damage, can dismantle both and maintain the change to the person that damages, thereby avoided local damage and need maintain the change to the main part, reduced the maintenance replacement cost to hair-dryer 1000.

Because the diffuser 100 in this scheme is equipped with two at least first exhaust vents 30a in air-out end 10b, and the air-out direction of two at least first exhaust vents 30a is clockwise interval distribution or anticlockwise interval distribution around the center of air-out end 10 b. The first air outlet holes 30a are arranged in such a way that the air flow can form a vortex shape after flowing out of at least two first air outlet holes 30a, and compared with the linear air flow flowing out of the diffuser 100 in the prior art, the vortex-shaped air flow increases the contact area with the hair, thereby improving the blowing effect of the hair dryer 1000.
Referring to fig. 2, in an embodiment of the present invention, the air outlet end 10b is formed with an air outlet end surface 10c, the diffuser 100 further includes at least two first protruding pillars 30 disposed on the air outlet end surface 10c, the at least two first protruding pillars 30 are both communicated with the air outlet end 10b, and a first air outlet 30a is disposed on an outer circumferential surface of one first protruding pillar 30.

The second protruding columns 50 may be at least two, the at least two second protruding columns 50 are located inside the at least two first protruding columns 30, and the at least two second protruding columns 50 are evenly distributed around the center of the air outlet end 10b at intervals. Thus, the air output of the diffuser 100 at the second convex column 50 and the uniformity of the air output are improved. Further, the third air outlet 50a may penetrate through the lateral periphery of the second stud 50. That is, after passing through the second air hole, the air flow in the diffuser 100 may be partially blown toward the center of the air outlet end 10b, or partially blown toward the periphery of the air outlet end 10b, so as to further increase the degree of diversification of the air outlet direction of the diffuser 100.
In an embodiment of the invention, the third air outlet 50a is disposed in a strip shape and extends along a side of the second protruding pillar 50 far away from the air outlet end face 10c to a side close to the air outlet end face 10 c.
