The first linking arm 31 can be driven to move together in 21 motion processes.
Second end of the second linking arm 32 is rotatably connected on pedestal 1 by the second rotating shaft 7, the second rotating shaft 7 and first turn
Axle 5 be arranged in parallel.There is fan groove 321 on second linking arm 32, in the present embodiment, projection is given birth in the side of the second linking arm 32
Limiting plate, limiting plate upper part missing are set to form the fan groove 321.It is convexly equipped with and is stretched into the fan groove in second rotating shaft 7
Limited block 71 in 321, so during the second linking arm 32 rotates relative to the second rotating shaft 7, the limited block 71 is spacing
The rotational angle of second linking arm 32, i.e., the rotational angle of spacing smoke barrier 6, avoid the rotational angle of smoke barrier 6 excessive and clap pressure
On the miscellaneous part of range hood.
The use process of the rotating mechanism of the range hood smoke barrier is as follows：Range hood will be in use, user beats manually
Smoke barrier 6 is opened, with the rotation of smoke barrier 6, pulls connecting bracket 22, swing arm 21 to act together, swing arm 21 is around being fixedly connected on
First rotating shaft 5 on pedestal 1 rotates, while swing arm 21 pulls the first linking arm 31 to be rotated relative to the second linking arm 32,
In the process, the second linking arm 32 is rotated around the second rotating shaft 7 being fixedly connected on pedestal 1, the axle center of the 3rd rotating shaft 8
Moved to the line direction in the axle center of first rotating shaft 5, the axle center of the second rotating shaft 7.After smoke barrier 6 opens certain angle, the 3rd rotating shaft 8
Axle center be moved on the line in the axle center of first rotating shaft 5, the axle center of the second rotating shaft 7, now the first linking arm 31, the second linking arm 32
Between angle cause torsion spring 4 to be in the most strong state of accumulation of energy.Now, user manually with the power of very little by smoke barrier 6 continue to
Loosed one's grip after upper upset low-angle, be then in release energy accumulating state in torsion spring 4, torsion spring 4 drives the first linking arm 31, the second linking arm
32 relatively rotate, and then drive swing arm 21 to rotate, and drive smoke barrier 6 to automatically continue opening, while in the effect of damper 100
Under, the smooth rotation of smoke barrier 6, and the end wall of fan groove 321 encounters the limited block in the second rotating shaft 7 on the second linking arm 32
When 71, smoke barrier 6 is opened to set angle, and smoke barrier 6 stops.
When needing to close smoke barrier 6, then on the offensive move of user downwardly turns over smoke barrier 6, when smoke barrier 6 closes certain angle
Afterwards, the axle center of the 3rd rotating shaft 8 re-move to the axle center of first rotating shaft 5, the axle center of the second rotating shaft 7 line on, now first connection
Angle between arm 31, the second linking arm 32 causes torsion spring 4 to be in the most strong state of accumulation of energy again, and user is further continued for the power with very little
Loosed one's grip after downwardly turning over smoke barrier 6, the first linking arm 31 and the second linking arm 32 are then relative in the presence of torsion spring 4 discharges accumulation of energy
Rotate, and then drive smoke barrier 6 to automatically continue and rotated to closing direction, fan groove 321 is another equally on the second linking arm 32
When one end wall encounters the limited block 71 in the second rotating shaft 7, smoke barrier 6 reaches closing position, and the stopping of smoke barrier 6 acts, while
Under the twisting force of torsion spring 4, smoke barrier 6 can realize the tight closure on range hood.
