Specifically, the top of the wind door panel 23 is connected to the door frame 22 through the elastic hinge 3, and the elastic hinge 3 provides an elastic force to the wind door panel 23, so that the bottom end of the wind door panel 23 tends to swing toward the door frame 22, and the wind door panel 23 is tightly combined with the door frame 22 in a non-working state. When the dust suction opening 21 is opened, the dust inlet opening formed by the air door plate 23 and the door frame 22 faces downwards, and compared with the dust inlet opening, the dust inlet opening faces upwards, the smoke dust is more easily settled on the bottom surface of the air draft air duct 1, and the smoke dust cannot float to cross the setting height of the linear driver 24, so that the smoke dust is reduced to be attached to the linear driver 24.

Further, referring to fig. 5 and 7, the transmission assembly 4 includes a support 41 disposed at an output end of the linear actuator, a push wheel 42 rotatably disposed at one side of the support 41, and a guide block 43 disposed at a side portion of the wind plate 23 in an inclined manner, wherein a guide groove 44 is disposed on the guide block 43, and the push wheel 42 is slidably connected with the guide groove 44 on the guide block 43. When the linear driver 24 drives the support 41 and the push wheel 42 arranged on the support 41 to move vertically upwards, the push wheel 42 in the guide groove 44 drives the guide block 43 and the air door plate 23 to turn upwards, and the contact point of the push wheel 42 and the guide groove 44 of the guide block 43 is changed at any moment in the turning process, and the friction force formed by the push wheel 42 and the guide groove 44 is converted into the self-rotating force of the push wheel 42 due to the rotation of the push wheel 42, so that the guide block 43 cannot be interfered with the smooth turning.
