The reinforcing member 31 supports the driving assembly 41 in a first direction and supports the connecting rod assembly 42 in a second direction, so that the driving assembly 41 and the connecting rod assembly 42 can be stably supported and stressed in different directions, so as to avoid force concentration on the smoke collecting hood 10.

[0059] The reinforcing member 31 supports the driving assembly 41 in a first direction and supports the linkage assembly 42 in a second direction, so that the driving assembly 41 and the linkage assembly 42 are connected at different positions of the reinforcing member 31, and the driving assembly 41 and the linkage assembly 42 apply external forces to the reinforcing member 31 in different directions during the movement, so as to disperse the stress of the reinforcing member 31 and avoid stress concentration of the smoke hood 10.

[0060] In the embodiment, the driving mechanism 40 includes the driving assembly 41, two groups of linkage assemblies 42, and a rotating shaft 43 connected between the two groups of linkage assemblies 42. The two groups of linkage assemblies 42 are arranged in the left-right direction of the smoke hood 10, the linkage assemblies 42 are connected with the guide vane 20, and the driving assembly 41 is connected with one group of linkage assemblies 42. The driving assembly 41 drives one group of linkage assemblies 42 to move, drives the rotating shaft 43 to rotate, and then drives the other group of linkage assemblies 42 to move, so as to drive the guide vane 20 by the two groups of linkage assemblies 42, and make the guide vane 20 bear the stress evenly.

[0061] The reinforcing member 31 can be arranged in one, and the reinforcing member 31 extends in the left-right direction of the smoke hood 10 to support the two groups of linkage assemblies 42.

In this embodiment, the connecting plate 4212 is arranged perpendicularly relative to the base body 4211, which is convenient for arranging the components in space.

[0070] The reinforcing member 31 provides support for the mounting bracket 412 supporting the driving member 411 and the mounting seat 421 supporting the first connecting rod 422 and the second connecting rod 423, and the external force applied to the mounting bracket 412 and the mounting seat 421 can be transmitted to the reinforcing member 31 to avoid deformation of the smoke hood 10.

[0087] When opening, the driving member 411 is elongated to drive the first connecting rod 422 to rotate around the axis of the rotating shaft 43, and then drive the rotating shaft 43 to rotate around the axis of the rotating shaft 43, and the rotating shaft 43 transmits the rotation to the other first connecting rod 422, and the two first connecting rods 422 push the air deflector 20 to flip forward, at the same time, the second connecting rod 423 rotates around the mounting seat 421, and the swing rod 44 rotates around the axis of the rotating shaft 43, and in the rotating process, the swing rod 44 pushes the movable smoke hood 102 to flip forward to open.

[0088] When closing, the driving member 411 is shortened to drive the first connecting rod 422 to rotate around the axis of the rotating shaft 43, and then drive the rotating shaft 43 to rotate around the axis of the rotating shaft 43, and the rotating shaft 43 transmits the rotation to the other first connecting rod 422, and the two first connecting rods 422 pull the air deflector 20 to flip backward, at the same time, the second connecting rod 423 rotates around the mounting seat 421, and the swing rod 44 rotates around the axis of the rotating shaft 43, and in the rotating process, the swing rod 44 pulls the movable smoke hood 102 to flip backward to close.

[0089] Since the air deflector 20 and the movable smoke hood 102 share one driving mechanism 40, the driving mechanism 40 is arranged near the top of the movable smoke hood 102 to take into account the air deflector 20 and the movable smoke hood 102. In order to ensure the stability of the movement of the movable smoke hood 102, the upper part of the movable smoke hood 102 is connected with the swing rod 44 of the driving mechanism 40, and the lower part of the movable smoke hood 102 is rotatably connected with the fixed smoke hood 101 through a supporting shaft, the supporting shaft extends along the second axis, and the swing rod 44 can transmit power to the movable smoke hood 102 to make the movable smoke hood 102 rotate around the second axis.

[0090] In summary, the smoke collecting device provided by the embodiment can not only increase the structural strength of the smoke hood 10, but also provide support for the driving mechanism 40 by arranging the reinforcing assembly 30. The mounting bracket 412 and the mounting seat 421 are connected with the reinforcing member 31, the stress of the reinforcing member 31 is dispersed, the mounting bracket 412 provides support for the driving member 411, the mounting seat 421 provides support for the connecting rod assembly 42, and the reinforcing member 31 is provided with two, so that the air deflector 20 is uniformly stressed at both ends.
