In some embodiments of the present invention, as shown in fig. 3 and 4, the driving mechanism 20 includes: a chute assembly 21, a linkage 22 and a drive device 23.

The sliding chute assembly 21 is disposed on the box assembly 10 and has a sliding chute 211, one end of the connecting rod 22 is provided with a sliding block 223 matched with the sliding chute 211, and the other end of the connecting rod is fixed on the full screen 30, the driving device 23 is connected with the connecting rod 22, and the sliding block 223 slides in the sliding chute 211 through the driving connecting rod 22 to lift and turn the full screen 30.

Specifically, the box assembly 10 is provided with a chute assembly 21 and a driving device 23, a chute 211 is defined on the chute assembly 21, one end of the connecting rod 22 is provided with a sliding block 223 matched with the chute 211, the other end of the connecting rod 22 is fixed on the full screen 30, the driving device 23 is pivotally connected with the connecting rod 22 and can drive the connecting rod 22 to move, and the connecting rod 22 moves and drives the sliding block 223 to slide along the chute 211, so that the connecting rod 22 drives the full screen 30 to move along a preset track. As shown in fig. 3, when the slider 223 is located at one end of the chute 211, the full screen 30 is located at a position closing the air inlet 11; as shown in fig. 4, when the driving device 23 drives the link 22 to move to the position where the slider 223 slides to the other end of the chute 211, the full screen 30 is lifted by a distance and turned over a certain angle, and at this time, the air inlet 11 is completely opened. Therefore, the driving mechanism 20 is simple in structure, and the movement track of lifting and overturning the full screen 30 is stable.

According to some specific examples of the present invention, as shown in fig. 6, the slide groove 211 includes: a lifting section 2111 and a flipping section 2112. When the sliding block 223 slides along the lifting section 2111, the connecting rod 22 drives the full screen 30 to lift relative to the box assembly 10, the overturning section 2112 is connected with the lifting section 2111 and is obliquely arranged relative to the lifting section 2111, and when the sliding block 223 slides into and out of the overturning section 2112, the connecting rod 22 drives the full screen 30 to overturn relative to the box assembly 10.

Specifically, as shown in fig. 3 and 4, the lifting section 2111 is inclined from bottom to top to front, the flipping section 2112 is connected to an end of the lifting section 2111 adjacent to the upper side, and the flipping section 2112 is inclined upward with respect to the lifting section 2111. During the sliding process of the sliding block 223 along the lifting section 2111, the connecting rod 22 drives the full screen 30 to move upwards or downwards relative to the box assembly 10; when the slider 223 slides into or out of the turn section 2112, the slider 223 turns within the chute 211 such that the link 22 connected to the slider 223 turns the full screen 30, and the angle at which the full screen 30 turns is equal to the angle at which the slider 223 turns within the chute 211, and the maximum angle at which the slider 223 turns within the chute 211 is equal to the angle between the turn section 2112 and the lift section 2111, and thus the maximum angle at which the full screen 30 can turn is equal to the angle between the lift section 2111 and the turn section 2112.

Further, the front wall of the box assembly 10 is inclined from bottom to top, and the included angle between the lifting section 2111 and the vertical direction is larger than the included angle between the front wall of the box assembly and the vertical direction. It will be appreciated that the motion trace of the full screen 30 is parallel to the motion trace of the slider 223 during the sliding of the lift section 2111. In the process that the sliding block 223 slides upwards from one end of the lifting section 2111 adjacent to the lower side, the distance between each point on the full screen 30 from bottom to top and the front wall of the box assembly 10 is gradually increased, so that when the sliding block 223 slides to the other end of the lifting section 2111 to enter the overturning section 2112, sufficient space exists between the full screen 30 and the front wall of the box assembly 10 to enable the connecting rod 22 to drive the full screen 30 to overturn.
