The blade seat 353 is fixedly connected to an air outlet seat of the lower portion 102 of the air outlet 10.
In order that the swing blade 35 can be easily deformed to better change the air guide angle, such that the blade body 351 may swing at a larger angle and the swing resistance may be reduced, the elastic connecting part 355 may be of an elongated shape, and an upper end of the elastic connecting part 355 may be connected to an inner edge of the blade body 351.
Preferably, in the present embodiment, the upper end of the elastic connecting part 355 may be connected to an upper end of the inner edge of the blade body 351, to efficiently reduce the connection portion between the elastic connecting part 355 and the blade body 351 and increase the swing flexibility of the blade body 351.
The blade body 351 may be fixedly connected to the base 31 via the elastic connecting part 355 and the blade seat 353. The elastic connecting part 355 and the blade body 351 may be made into one piece, or be formed separately. The elastic connecting part 355 and the blade seat 353 may be made into one piece, or be formed separately. The blade seat 353 may be fixedly connected to the base 31 in an inserted coupling manner, and accordingly, the base 31 may be provided with the corresponding number of grooves. Generally, the blade body 351 may be made of an elastic material that can be bent, such that the blade body 351 can be driven by the transmission mechanism 33 to swing left of right under the elastic force.
In order that the swing blade mechanism 3 can be detached for cleaning or maintaining, each blade body 351 may be connected to the transmission mechanism 33 in a snap-fit coupling manner. The transmission mechanism 33 may be a connecting rod, and each swing blade 35 may be connected to the connecting rod in a snap-fit coupling manner.

The blade notch 352 may be provided at a middle portion of an outer edge of each blade body 351 and is located at the opposite side of the elastic connecting part 355.
When the swing blade mechanism 3 is operated, the connecting rod is rotated under the drive of the drive output end of the swing motor, and thus drives the blade body 351 of each swing blade 35 to swing left or right so as to perform the air sweep, thereby achieving the adjustment of a relatively large air discharging angle.
As shown in figure 4, in order to further facilitate the adjustment of the swing angle of the swing blades 35, and also to avoid the circumstance in which the direction of the air can not be adjusted due to the breakdown of the swing motor, the swing blade mechanism 3 may further includes a manual adjusting device.
