In an embodiment of the present invention, the protruding portion 135 is disposed on the fixed cover 13, and the accommodating groove 1236 is disposed on the air guiding member 123; in another embodiment of the present invention, the protruding portion 135 is disposed on the air guiding member 123, and the receiving groove 1236 is disposed on the fixed cover 13.

The specific positions of the protruding portion 135 and the receiving groove 1236 can be selected by the setting staff according to the actual situation.

Specifically, in a preferred embodiment of the present invention, the protruding portion 135 is disposed on the fixed cover 13, and the receiving groove 1236 is disposed on the air guide 123.

In summary, when the air-out structure is in the initial state, the groove 1223 is matched with the protrusion 1222, the second air guiding portion 1232 of the air guiding member 123 is in contact with the inner housing 112, and the air-out assembly 12 is at the first position;

the driving mechanism 121 drives the rotating member 122 to rotate, so as to control the driving portion 1234 to gradually move towards the top end of the protruding portion 1222, and further control the air guiding member 123 to move upwards along the vertical direction, and simultaneously the elastic element 16 is compressed to deform to generate elastic force;

when the air-out driver 121 controls the driving part 1234 to be matched with the top end of the cam part 1222, the first air guiding part 1231 of the air guiding member 123 is contacted and connected with the outer wall 111 of the housing 11, and the air-out assembly 12 is at the second position;

the driving mechanism 121 continues to drive the rotating member 122 to rotate, and the driving portion 1234 gradually moves towards the groove 1223 under the elastic force of the air-out driver 121 and the elastic element 16, so as to control the air-guiding member 123 to move downward along the vertical direction, so as to control the air-out assembly 12 to switch from the second position to the first position.

According to the invention, the plurality of elastic elements 16 are arranged between the fixed cover 13 and the air guide 123 to buffer the air guide 123 and provide elastic force for resetting, so that the air guide 123 can be effectively protected.

The invention also relates to a hair dryer 1 comprising an air outlet structure according to any of the above.

Further, the blower 1 further includes a holding portion 17, and a fan blade and a motor for driving the fan blade to rotate are disposed in the holding portion 17, where the fan blade is communicated with the air outlet structure.

In a preferred embodiment of the present invention, the fan blade is communicated with the inlets of the first air outlet channel 14 and the second air outlet channel 15, and the air outlets of the first air outlet channel 14 and the second air outlet channel 15 are communicated with the outside.

It can be appreciated that the motor drives the fan blade to rotate so as to form a blowing air in the holding portion 17, and the formed blowing air is discharged through the blowing structure, so that the blower 1 is normally used.

It should be understood that the embodiments described above are merely illustrative of portions of the present application and are not intended to limit the scope of the present application.

In this specification, each embodiment is described in a progressive manner, and identical and similar parts of each embodiment are all referred to each other, and each embodiment mainly describes differences from other embodiments. In particular, for system embodiments, since they are substantially similar to method embodiments, the description is relatively simple, as relevant to see a section of the description of method embodiments.
