The first partition 30 is parallel to the air flow direction of the air outlet channel 20, and the laying direction of the micro holes 31 therein is naturally parallel to the air flow direction. The first separator 30 separates the casing 10 into inner and outer cavities distributed along the radial direction, the outer cavity is formed as a closed cavity 40, and the inner cavity is formed as an air outlet channel 20. Because the inner space of the shell is limited, the inner cavity and the outer cavity matched with the shape of the shell can maximize the space, and meanwhile, the noise of certain local positions of the air outlet structure is avoided to be particularly obvious. The micropores referred to in the present application may be circular holes, square holes and other holes, and are preferably circular holes in the present embodiment. Aiming at different noise sources, the specific layout of the micropores and the cavity size of the closed cavity can be adjusted according to different noise reduction frequencies, such as the number of the micropores, the aperture, the wall thickness of the first isolating piece, the perforation rate, the distance between the first isolating piece and the shell and other parameters.

When the drying function is started, the axial flow fan 51 starts to work, and the airflow flows in from the orifice plate 73 of the inlet end 71, enters the fan assembly 50 through the tapered section 74 and then enters the air outlet structure. Because the axial flow fan 51 with the air volume not less than 13L/s is adopted, the air volume and the air speed entering the air outlet structure are greatly increased. When the airflow passes through the air outlet channel 20, since the first spacer 30 is provided with the micro-porous structure to allow the fluid in the air outlet channel 20 to pass through the micro-porous structure, when the sound wave enters the micro-porous structure, the air rubs in the micro-pores to generate wind resistance, consume sound energy and eliminate noise. When the airflow passes through the front section 21 of the air outlet channel and is heated by the heating assembly 60, warm airflow is formed and blown out from the rear section 22 of the air outlet channel by the air outlet 11. Because the air outlet channel rear section 22 is the convergent shape, consequently further compress the air current, the velocity of flow greatly increased forms high-speed warm flow. Because the flow velocity is very big (can reach more than 25 m/s), the warm current can also keep strong trend after breaking away from air outlet 11, cooperates the air-out direction, realizes the local quick drying of human body.
For the design of the air outlet structure, the air outlet structure may further include a second isolation member 80, the second isolation member 80 divides the closed cavity 40 into two chambers along the radial direction, and a plurality of micropores are also distributed on the side wall of the second isolation member 80. Therefore, two chambers are formed, so that the noise can be further reduced, and a better effect is achieved.
