[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5In this embodiment, a noise reduction outer skin of a dryer includes a drying tube 1. An adjustment mechanism 2 is provided outside the drying tube 1. The adjustment mechanism 2 includes a noise reduction outer skin 3 movably installed on the outer peripheral wall of the drying tube 1. An extension head 4 is fixedly connected to the outer peripheral wall of the noise reduction outer skin 3. A first limiting groove 5 is opened in the extension head 4. A second limiting groove 6 is opened in the extension head 4.

[0025] It should be noted that, in order to facilitate the limiting of the extension head 4, the second limiting groove 6 is a square groove. In order to increase the limiting effect of the first limiting groove 5 and the second limiting groove 6, the first limiting groove 5 and the second limiting groove 6 are not located in the same position plane.

[0026] It should be noted that in order to facilitate the installation inside the noise reduction outer skin 3 through the bottom plate 7, the bottom plate 7 is fixedly connected inside the noise reduction outer skin 3, and the end of the bottom plate 7 away from the noise reduction outer skin 3 is fixedly connected to the sound insulation layer 8.

[0027] It should be noted that one end of the sound insulation layer 8 away from the bottom plate 7 is fixedly connected to the crest sound absorbing sponge layer 9 , and one end of the crest sound absorbing sponge layer 9 away from the sound insulation layer 8 is fixedly connected to the top plate 10 .

[0028] It should be noted that, in order to increase the sound insulation effect, the sound insulation layer 8 is irregular, and in order to increase the sound insulation effect, the bottom plate 7 is matched with the sound insulation layer 8 .

[0029] It is understandable that in order to increase the sound insulation effect, the length of the peak sound-absorbing sponge layer 9 is equal to the length of the top plate 10 , and the length of the top plate 10 is equal to the length of the bottom plate 7 .

[0030] The working principle of the above embodiment is:

[0031] When the user needs to remove the noise reduction outer skin, the user rotates the extension head 4 to disengage the extension head 4 from the first limiting groove 5 and the second limiting groove 6 .
