The plurality of louvers 2 are rotatably connected to the fixing member 1, and the plurality of louvers 2 are disposed at intervals along a length direction (e.g., an up-down direction shown in fig. 2) of the fixing member 1, and the plurality of louvers 2 include a first louver 21 and a second louver 22. The connecting rod 3 is connected with the plurality of louvers 2, and the connecting rod 3 is movable along the length direction (for example, the up-down direction shown in fig. 2) of the fixing member 1 to drive the plurality of louvers 2 to swing, thereby adjusting the air supply direction. That is, the connecting rod 3 is connected to the first louver 21 and the second louver 22, and the connecting rod 3 is movable along the length direction (e.g. up-down direction shown in fig. 2) of the fixing member 1 to drive the first louver 21 and the second louver 22 to swing, thereby adjusting the air supply direction

In an embodiment of the present invention, referring to fig. 6, the plurality of louvers 2 may further have a second air guiding state (for example, the state where the plurality of louvers 2 are shown in fig. 6), where the plurality of louvers 2 are in the second air guiding state, and the first louver 21 and the second louver 22 are parallel to each other. That is, the plurality of louvers 2 have a first air guiding state and a second air guiding state, and the plurality of louvers 2 are switchable between the first air guiding state and the second air guiding state, when the plurality of louvers 2 are in the first air guiding state, the first louvers 21 and the second louvers 22 are disposed at an angle, and when the plurality of louvers 2 are in the second air guiding state, the first louvers 21 and the second louvers 22 are parallel to each other. Thus, different air guiding modes of the air conditioner can be realized.
In some embodiments of the present invention, the first louver 21 may include a plurality, the second louver 22 may include a plurality, and the plurality of first louvers 21 and the plurality of second louvers 22 are alternately arranged along the length direction (e.g., up-down direction as shown in fig. 2) of the fixing member 1.

Here, the first fixing shaft 211 and the second fixing shaft 221 are flush, meaning that an end portion of one end of the first fixing shaft 211 connected to the fixing member 1 is aligned with an end portion of one end of the second fixing shaft 221 connected to the fixing member 1 in the up-down direction. For example, as shown in fig. 2, the first fixing shaft 211 and the second fixing shaft 221 extend in a horizontal direction and are disposed in parallel with each other in an up-down direction, and the free end of the first fixing shaft 211 and the free end of the second fixing shaft 221 are aligned up-down, the fixing member 1 is provided with a first shaft hole and a second shaft hole which are disposed at intervals along a length direction of the fixing member 1, the free end of the first fixing shaft 211 is rotatably disposed in the first shaft hole, and the free end of the second fixing shaft 221 is rotatably disposed in the second shaft hole.

Wherein the distance between the first link shaft 212 and the fixing member 1 is not equal to the distance between the second link shaft 222 and the fixing member 1 in the direction perpendicular to the length direction of the fixing member 1. Therefore, on the premise that the first louver 21 and the second louver 22 are arranged in an included angle in the first air guiding state, the structures of the connecting rod 3, the louver 2 and the fixing piece 1 can be simplified.

Further, the distance between the first link shaft 212 and the open end edge of the first escape groove 213 is not equal to the distance between the second link shaft 222 and the open end edge of the second escape groove 223. In this way, the distance between the first link shaft 212 and the fixing member 1 and the distance between the second link shaft 222 and the fixing member 1 may be made unequal, so that the first louver 21 and the second louver 22 are disposed at an included angle in the first wind guiding state.
