The invention discloses a visible air flow indicator. A fixing shaft is arranged on a transparent cylinder; a wind disk is mounted on the fixing shaft through a bearing and can rotate around the fixing shaft; a plurality of air holes are formed in the wind disk; a scale is arranged on a side surface of the transparent cylinder; air enters the transparent cylinder from the bottom of the cylinder, and when the air passes through the air holes formed in the wind disk, the wind disk is driven to rotate, so that the wind disk is hovered in the transparent cylinder; and the air volume is obtained through the position corresponding to the scale, of the wind disk. The visible air flow indicator has the advantages that: the deodorizing air duct has the visible air flow indicator, and the air volumeof the deodorizing air duct can be instantly and accurately read out by observing the scale, thereby realizing the adjustment of the air volume of the deodorizing air duct on site; the cost of the visible air flow indicator
