In the technical scheme, the axial displacement force transmission piece 3 is used as a stress force transmission part for adjusting the axial displacement of the air deflector 2, the force applied to the axial displacement force transmission piece can be transmitted to the air deflector 2, so that the air deflector 2 is forced to generate corresponding axial displacement, gaps between the end surfaces of the two axial ends of the air deflector 2 and corresponding wall bodies of the air outlet 11 can be adjusted, the gaps on the two sides can be relatively uniform by adjusting the axial displacement of the air deflector 2 when a single-side gap is too large, the phenomenon of 'black gaps' of the appearance of an air conditioner in the prior art is effectively avoided, and customer complaints are prevented from being caused.
As a specific embodiment of the axial displacement force transmission member 3, preferably, the axial displacement force transmission member 3 includes a force-bearing plate 31 and a connecting pin 32 located at one side of the force-bearing plate 31, the connecting pin 32 is inserted into a first axial hole formed in the first rotating shaft 21, and axial positions of the connecting pin 32 and the first rotating shaft 21 are kept unchanged, so that the axial displacement force transmission member 3 is fixedly connected with the air deflector 2, consistency between axial displacement of the axial displacement force transmission member 3 and axial displacement of the air deflector 2 is further realized, and accuracy of displacement adjustment is ensured; preferably, a first shaft sleeve 61 is sleeved on the circumferential outer side of the first rotating shaft 21 to reduce wear of a mounting contact surface between the first rotating shaft 21 and the first wall body, so that pivoting is smoother.
Preferably, the first wall body is provided with a plurality of guide posts 111, specifically, the plurality of guide posts 111 are disposed on a side of the first wall body away from the air deflector 2, the force-receiving plate body 31 is provided with a plurality of guide holes 33, the number of the guide holes 33 is the same as that of the guide posts 111, and the plurality of guide posts 111 are respectively inserted into the plurality of guide holes 33 in a one-to-one correspondence manner, so that the axial displacement of the force-receiving plate body 31 is guided by the guide posts 111, and the stability and reliability of the axial movement are ensured.

Specifically, when | -La-Lb |. D, it means that the gaps at both ends of the air deflection panel 2 in the axial direction are uniform, and the appearance is not affected, so that the force application member 4 is controlled not to operate; or, when | -La-Lb | ≧ D, it indicates that the gaps at the two axial ends of the air deflection plate 2 are not uniform enough, and at this time, it is necessary to adjust the axial displacement of the air deflection plate 2, so it is necessary to control the operation of the force application member 4.
Specifically, the force application member 4 includes a first rotating electrical machine 41, and when | La-Lb | > D, controlling the operation of the force application member 4 includes: when La > Lb, controlling the first rotating motor 41 to rotate along a first rotation direction so as to move the air deflector 2 toward a side close to the first wall body; or, when La < Lb, the first rotating motor 41 is controlled to rotate in the second rotation direction so as to move the air deflector 2 toward the side away from the first wall body.
