After this assembly, the first gear 410 is inserted into the mounting boss 316 of the mounting base 315, and then the second gear 420 is inserted into another mounting boss 316 of the mounting base 315. This transmission assembly design improves the efficiency of power transmission from the impeller, facilitating the subsequent oscillation of multiple guide vanes.

[0027] See Figure 6The linkage assembly 500 of this utility model includes a rotating guide rod 510 and a swing guide rod 520. Further, the rotating guide rod 510 has a first rotating guide rod through hole 511 and a second rotating guide rod through hole 512 at both ends; the swing guide rod 520 includes a long strip-shaped main body 521 and several extension portions 522 protruding outward from one side of the long side of the main body 521. The short side of the main body 521 has long strip-shaped first through holes 523 and second through holes 524, and a columnar protrusion 525 protrudes from its end face facing the rotating guide rod 510. The extension portions 522 have long strip-shaped extension portion through holes 526. See [link to relevant documentation]. Figure 3 and Figure 6 During assembly, the first rotating guide rod through hole 511 is connected to the mounting post 421 of the second gear, and the second rotating guide rod through hole 512 is connected to the protrusion 525 of the swing guide rod.

The guide part 610 of the air guide plate is inserted and installed on the extension through hole 526. After the assembly is completed, the swing guide rod 520 can only move back and forth on the bracket under the restriction of the first through hole 523 and the second through hole 524 of the swing guide rod because it is inserted and installed on the first guide post 311 and the second guide post 312. Similarly, the guide part 610 of the air guide plate 600 is inserted and installed on the extension through hole 526 of the swing guide rod 520, and the air guide plate 600 can only swing back and forth with the swing guide rod. The above design can convert the rotational motion of the impeller into the reciprocating oscillation of the air guide plate. It can achieve the oscillation adjustment of the blowing angle without the need for additional electrical equipment. It has low energy consumption and a compact and reliable structure.

[0028] See Figure 3 , Figure 4 and Figure 7 To facilitate the assembly of the air guide plate, the air guide plate 600 in this embodiment includes a plate-shaped air guide plate main body 630.

[0030] The motion principle of the air guiding device of this utility model is as follows: Figure 8As shown, during operation, the air blown by the fan drives the impeller 320 to rotate. The impeller 320 drives the first gear 410 and the second gear 420 to rotate. The second gear 420 drives one end of the rotating guide rod 510 to rotate. At this time, the other end of the rotating guide rod 510 drives the swing guide rod 520 to move to the right from the left extreme position, and drives the air guide plate 600 to swing to the right (see...). Figure 8 (c); When the swing guide rod 520 reaches the right limit position, the swing guide rod 520 moves to the left under the drive of the rotating guide rod 510, and drives the air guide plate 600 to swing to the left (see ac); Figure 8 (d) When the rotating guide rod 510 drives the swing guide rod 520 to the left limit position, it repeats the action of moving from the left limit position to the right to realize the automatic swing of the air guide plate.
