In some embodiments of the present invention, as shown in FIG. 5, the connecting rod assembly 22 further includes: a connecting plate 221, a slide bar 222, a first connecting rod 223, and a second connecting rod 224.

The connecting plate 221 is fixed to the full-face screen 30, the first sliding member 2221 and the second sliding member 2222 are respectively disposed at two ends of the sliding rod 222, two ends of the first connecting rod 223 are respectively connected to one end of the sliding rod 222 adjacent to the first sliding member 2221 and the connecting plate 221, the first connecting rod 223 is provided with a pivot hole 2231 pivotally connected to the driving device 23, and two ends of the second connecting rod 224 are respectively connected to one end of the sliding rod 222 adjacent to the second sliding member 2222 and the connecting plate 221. It should be noted that the first sliding member 2221 and the second sliding member 2222 are located on a side of the sliding bar 222 facing the sliding slot and are respectively disposed adjacent to two ends of the sliding bar 222, and the side of the sliding bar 222 facing the sliding slot is the right side of the sliding bar 222 shown in fig. 5.

In some specific examples of the present invention, as shown in fig. 6, the pivot hole 2231 is located at an end of the first link 223 adjacent to the first slider 2221, and the pivot hole 2231 penetrates the first link 223 in a direction perpendicular to a plane formed by the first slide groove 211 and the second slide groove 212 (i.e., a left-right direction not shown in fig. 3 and 4), that is, an extending direction of the pivot hole 2231 is perpendicular to a plane formed by the first slide groove 211 and the second slide groove 212, so that a pivoting axis of the link assembly 22 relative to the driving device 23 is perpendicular to a moving track of the link assembly 22, and the link assembly 22 is pivoted relative to the driving device 23 more effectively, so that the driving device 23 drives the link assembly 22 to move along a predetermined track.

Optionally, with continued reference to the embodiment shown in fig. 6, a pivot slot 2232 is provided on the first connecting rod 223 for receiving a hinge, the pivot slot 2232 being in communication with the pivot hole 2231. Specifically, the pivot groove 2232 extends through the first link bar 223 in a width direction of the first link bar 223, the pivot groove 2232 extends perpendicular to the extending direction of the pivot hole 2231, and the hinge may be a pivot shaft inserted into the pivot hole 2231, so that the driving device 23 does not interfere with the driving of the link assembly 22, thereby further improving the pivoting effect of the link assembly 22 and the driving device 23.

Further, with continued reference to the embodiment shown in fig. 5, the first connecting rod 223, the second connecting rod 224 and the sliding rod 222 are provided with weight-reducing grooves 227. The lightening grooves 227 are formed by inwardly recessing the side surfaces of the first connecting rod 223, the second connecting rod 224, and the slide bar 222, respectively, whereby the overall weight of the link assembly 22 can be lightened, the load of the driving device 23 can be lightened, and the manufacturing cost of the link assembly 22 can be reduced.

In some embodiments of the present invention, as shown in fig. 3 and 4, the first runner 211 has a first start 2111 and a first end 2112, the second runner 212 has a second start 2121 and a second end 2122, the first start 2111 is spaced from the second start 2121 by a distance equal to the first end 2112 is spaced from the second end 2122, and the maximum distance between the first runner 211 and the second runner 212 is no greater than the distance between the first slider 2221 and the second slider 2222. Specifically, the first start end 2111 and the first end 2112 are respectively located at two ends of the first sliding groove 211, the second start end 2121 and the second end 2122 are respectively located at two ends of the second sliding groove 212, and the maximum distance between the first sliding groove 211 and the second sliding groove 212 is smaller than or equal to the distance between the first sliding element 2221 and the second sliding element 2222, so that the second sliding element 2222 can slide relative to the second sliding groove 212 while the first sliding element 2221 slides relative to the first sliding groove 211, and the occurrence of jamming of the connecting rod assembly 22 is avoided.

When the first sliding member 2221 is located at the first start end 2111 and the second sliding member 2222 is located at the second start end 2121, as shown in fig. 3, the full-face screen 30 closes the air inlet 11; when the first sliding member 2221 is located at the first terminal 2112 and the second sliding member 2222 is located at the second terminal 2122, as shown in fig. 4, the full-face screen 30 is raised to the maximum height and turned to the maximum angle to open the air inlet 11.

In some specific examples of the present invention, with continued reference to the embodiment shown in fig. 3 and 4, the first chute 211 is disposed below the second chute 212, the first chute 211 is disposed to be inclined upward in the horizontal direction in a direction toward the full screen 30, the second chute 212 is disposed to be inclined upward in the horizontal direction in a direction toward the full screen 30, and an acute angle between the first chute 211 and the horizontal direction is smaller than an acute angle between the second chute 212 and the horizontal direction.

Preferably, a line connecting the first terminal 2112 and the second terminal 2122 is parallel to the vertical direction. That is, when the entire screen 30 is raised to the maximum height and turned over by the maximum angle, the entire screen 30 is parallel to the vertical direction. Accordingly, the display effect of the full-face screen 30 is optimal, and the smoke collecting effect of the smoke collecting space formed between the full-face screen 30 and the case assembly 10 is optimal.
