## Abstract

A wind comb capable of adjusting the direction of wind includes a housing, multiple first teeth, multiple second teeth, a baffle, and a driving unit. The housing defines a first receiving cavity. The first tooth and the second tooth define a first and a second wind channel respectively, which are communicating with the first receiving cavity. A direction of wind blowing from the first wind channel is different from that of the wind blowing form the second wind channel. The baffle defines multiple first and second vents. Each first vent is communicating with a first wind channel, each second vent is communicating with a second exhaust. The driving unit is used to drive the baffle to cause the first vent to communicate with or isolate from the first wind channel, and to cause the second vent to communicate with or isolate from the second wind channel.
