In the embodiment of the present invention, as shown in fig. 1 to 3, the smoke barrier opening and closing mechanism includes a smoke barrier 100, a driving device 200, a first sensor 300, a second sensor 400, and a controller 500.
The smoke baffle 100 is movably arranged on a smoke collecting cover 1000 of the range hood, a smoke exhaust port 1001 is arranged on the smoke collecting cover 1000, and the smoke baffle 100 can open and close the smoke exhaust port 1001.
Specifically, the smoking opening 1001 may be designed as a rectangle, and the smoke barrier 100 is a rectangular plate having an area larger than that of the smoking opening 1001.
The driving device 200 is disposed between the smoke collecting hood 1000 and the smoke barrier 100, and the driving device 200 can drive the smoke barrier 100 to rotate relative to the smoke collecting hood 1000, so that the smoke barrier 100 is switched between opening and closing the smoke exhaust port 1001.

As shown in fig. 6, when the included angle between the smoke barrier 100 and the smoke collecting hood 1000 is 35 ° during the opening process of the smoke barrier 100, the smoke barrier is blocked by the foreign matters, the AD sampling value of the acting force fed back by the first sensor 300 is greater than the corresponding set threshold value in the controller 500, and at this time, the controller 500 may determine that the smoke barrier 100 is blocked by the foreign matters, so as to control the driving device 200 to stop operating.
In the embodiment of the utility model, the smoke baffle opening and closing mechanism is provided with the first sensor 300 for detecting the acting force of the driving device 200 on the smoke baffle 100 and the second sensor 400 for detecting the included angle between the smoke baffle 100 and the smoke collecting hood 1000, so that in the opening and closing processes of the smoke baffle 100, the acting force of the driving device 200 on the smoke baffle 100 and the included angle between the smoke baffle 100 and the smoke collecting hood 1000 are obtained in real time through the controller 500, and then compared with the corresponding set threshold value in the controller 500, whether the smoke baffle 100 is blocked by foreign matters is further judged, the operation of the driving device 200 is controlled, the smoke baffle 100 is reasonably controlled, meanwhile, the included angle between the smoke baffle 100 and the smoke collecting hood 1000 can be detected through the second sensor 400, whether the smoke baffle 100 is opened and closed in place is judged, and the accuracy of the opening and closing position of the smoke baffle 100 is improved.
In some embodiments, the driving device 200 is received in the smoking port 1001 when the smoke barrier 100 is in a state of closing the smoking port 1001.
Specifically, the drive device 200 may be connected between the inside of the smoke barrier 100 and the inside of the smoking port 1001. The driving device 200 can be accommodated in the smoke exhaust port 1001 when the smoke baffle 100 is in a closed state, so that the whole range hood is neat and beautiful.
In one embodiment, as shown in fig. 1-3, the driving device 200 is an electric putter having a motor end 211 and a putter end 221, the motor end 211 and the putter end 221 being rotatably connected to the smoke collecting hood 1000 and the smoke barrier 100, respectively.
Specifically, the electric push rod includes a motor 210 and a push rod 220, and the motor 210 provides power for the telescopic motion of the push rod 220. The motor end 211 and the rod end 221 of the electric push rod are both provided with hinged seats, and are respectively connected with the smoke collecting hood 1000 and the smoke baffle 100 in a rotating manner through pin shafts.
