For example, the ventilating mesh body on the air outlet can be divided into two regions, for example, a left region and a right region, corresponding tightening structures, such as motor-driven reel mechanisms, are arranged at the upper and lower edges of the left and right regions, and the left and right regions of the ventilating mesh body are respectively connected to the left reel mechanism and the right reel mechanism. The left reel mechanism and the right reel mechanism can independently wind the left area and the right area of the ventilating net body based on the instruction of the control system so as to respectively adjust the density of the grids of the left area and the right area.
