[0034] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.
[0035] Please also read Figures 1 to 8 Now, the air outlet structure for noise reduction provided in the embodiment of the present application is described. The air outlet structure for noise reduction includes: an air hood body 10.
