[0038] In an embodiment, the fixed frame 1 comprises a first mounting plate 5 and two support plates 6, the two support plates 6 are respectively detachably mounted at two ends of the first mounting plate 5, the upper and lower ends of the two support plates 6 extend and bend away from the ventilation opening 4 to form a groove 7, the movable frame 2 comprises a second mounting plate 8 and two extension plates 9, the two extension plates 9 are detachably mounted at two ends of the second mounting plate 8, and the two extension plates 9 are in sliding contact with the groove 7. Specifically, as shown in Figure 1 and Figure 3 The detachable mounting mode of the first mounting plate 5 and the two support plates 6 can adopt threaded connection, so that the first mounting plate 5 and the two support plates 6 are convenient to disassemble and assemble, and are beneficial to maintenance. Further, when the installation position of the movable frame 2 needs to be adjusted, the sliding contact between the two extension plates 9 and the groove 7 can ensure the stability of the movable frame 2 during the left and right movement adjustment, and improve the overall structural strength.

[0039] In an embodiment, the two support plates 6 are respectively provided with an adjusting groove 10 along the extending direction of each support plate 6, and the two extension plates 9 are respectively provided with a lock hole corresponding to the position of the adjusting groove 10, and the two extension plates 9 are detachably connected with the support plates 6 through a locking piece penetrating the lock hole and the adjusting groove 10.

The structural design is ingenious and reasonable. Furthermore, since the drive assembly is connected to several air guide plates 3, several guide plates can be rotated and adjusted relative to the fixed frame 1 under the drive of the drive assembly. At the same time, the ends of the two blades 16 away from the connecting block 15 are rotatably mounted on the first mounting plate 5 and the second mounting plate 8 through a clamp, thereby improving the stability of the guide plates during rotation adjustment.

[0043] In an embodiment, the driving assembly comprises a driving member 17, a driving gear, a driven gear 18, a mounting rod 19, a transmission rod 20 and a plurality of connecting rods 21, the driving gear is detachably mounted on the power output end of the driving member 17, the mounting rod 19 is connected with the sleeve of a blade 16, the driven gear 18 is arranged on the mounting rod 19 and engaged with the driving gear, the plurality of connecting rods 21 are evenly and spacedly arranged in parallel along the extension direction of the transmission rod 20, one end of the plurality of connecting rods 21 is detachably connected with the transmission rod 20, and the other end of the plurality of connecting rods 21 is respectively and correspondingly detachably connected with the sleeves of the plurality of blades 16.

[0044] In an embodiment, as shown in Figure 1 、 Figure 5 and Figure 6 , the upper and lower ends of the second mounting plate 8 extend and bend away from the air vent 4 to form a placing groove 22 for accommodating the driving gear, the driven gear 18, the mounting rod 19, the transmission rod 20 and the plurality of connecting rods 21, the baffle 23 is detachably mounted at the slot opening of the placing groove 22, and the driving member 17 is arranged on the baffle 23. As can be understood, by mounting the driving gear, the driven gear 18, the mounting rod 19, the transmission rod 20 and the plurality of connecting rods 21 in the placing groove 22 and shielding the slot opening of the placing groove 22 by the baffle 23, the structural components such as the driving gear, the driven gear 18 and the mounting rod 19 can be prevented from being exposed to the external environment, thereby ensuring the stability and reliability of the rotation adjustment of the plurality of air deflectors 3. Further, the detachable mounting of the baffle 23 can adopt threaded connection, thereby facilitating the disassembly and assembly of the baffle 23 and facilitating the replacement and maintenance of the components such as the driving gear, the driven gear 18 and the mounting rod 19.

[0045] In an embodiment, as shown in Figure 1 and Figure 5 , the air vent 4 is provided with a limiting rod 24 on both sides along the width direction thereof for abutting against the air deflector 3.
