Air outlet device

Abstract

An air outlet device comprises: a housing comprising an air inlet and an air outlet; and a vane assembly disposed inside the housing and extending along the length direction of the air outlet. The vane assembly comprises a plurality of vane units connected in series with each other, and the plurality of vane units are adapted to rotate synchronously around the axis of the vane assembly or, at least some of the vane units independently rotate around the axis of the vane assembly relative to the remaining vane units. A user is able to control all the vane units to rotate synchronously around the axis, or to control some of the vane units to rotate, the remaining vane units rotating with a delay, thus achieving regulating air flows from the air outlet device as a whole, or regulating the air flows from different sections of the air outlet respectively.
