The transmission member 82 moves along the first direction to drive the connecting rod 71 to move along the first direction, and the connecting rod 71 moves to drive the air guiding shutter 72 to move, so as to guide air flow in the air outlet channel 50 and adjust the air outlet direction of the air flow.

Referring to fig. 5, 16 and 17, according to some alternative embodiments of the present utility model, the driving member 82 is connected to the driving end 711 by a connecting member 83, and the connecting member 83 includes a first connecting section 831 and a second connecting section 832, and the first connecting section 831 and the second connecting section 832 are connected to each other and disposed at an angle. The first connecting section 831 extends in a third direction (for example, referring to the front-rear direction in the drawing), and the first connecting section 831 is connected to the transmission member 82; the second connection section 832 extends along a first direction, and the second connection section 832 is connected to the driving end 711, and a third direction intersects the first direction.

For example, the connecting member 83 may have an L-shape, the first connecting section 831 and the second connecting section 832 are connected to each other at right angles, the first connecting section 831 extends in the front-rear direction, and the second connecting section 832 extends in the up-down direction.

The installation positions of the driving mechanism 8 and the wind guiding structure 7 are easily limited by space, so that the transmission member 82 is inconvenient to be connected with the link 71. By designing the connecting element 83 to include the first connecting section 831 and the second connecting section 832 having different extending directions, the connecting sections are thereby connected to the connecting rod 71, whereby the transmission element 82 is connected to the connecting rod 71.

For example, the distance L1 between the first center line e1 and the second center line e2 in the third direction is 6mm, 7mm, 8mm, 9mm, or 10mm.

The distance L1 between the first center line e1 and the second center line e2 in the third direction may be considered as a power arm of the link 71, and the smaller the power arm is, the smaller the moment applied to the link 71 is, and the stronger the reliability of the link 71 is. For example, when the first center line e1 and the second center line e2 are located on the same straight line, the transmission member 82 drives the link 71 to move best, so that the reliability of the link 71 is the strongest.

Therefore, the distance L1 between the first center line e1 and the second center line e2 in the third direction is smaller than 12mm, so that the connecting rod 71 can be ensured to have a smaller force arm while the transmission member 82 is connected with the connecting rod 71 and drives the connecting rod 71 to move, the reliability of the connecting rod 71 is enhanced, and the service life of the connecting rod 71 is ensured.
