The two ends of the connecting arm are respectively hinged with the panel and the shell frame, so that the panel cannot be thoroughly far away from the shell frame. When the panel is separated from the shell frame to move, the panel firstly rotates by taking the hinged position of the connecting arm and the shell frame as a fulcrum, so that the panel is driven to turn over. At this time, the horizontal component force of the panel caused by the driving mechanism will gradually decrease with the turning angle of the panel. When the panel turns over to be perpendicular, because the articulated effect of panel and linking arm, the horizontal direction's that actuating mechanism caused to the panel component will disappear, and the panel will only bear the vertical direction's power to carry out elevating movement.

When the panel 10 is not moved, it will block the housing frame 30, thereby protecting the suction mechanism 40 inside the housing frame 30. During operation, the power source of the connecting mechanism provides power, so that the connecting mechanism drives the panel 10 to perform lifting motion and turnover motion simultaneously, thereby opening the accommodating cavity and enabling the range hood to operate. Because the turning motion and the lifting motion run simultaneously, the influence of the panel 10 on a user during turning can be effectively reduced, the cigarette gathering area is increased, and the operation is convenient. Meanwhile, since the panel 10 is less affected by a user when turned over, the size of the panel 10 can be increased with ease, thereby increasing the area of operation and display.
The connecting mechanism comprises a driving mechanism and a driven mechanism, the driving mechanism can drive the panel 10 to perform turnover motion, and the driven mechanism can drive the panel 10 to perform lifting motion when the panel is turned. The driven mechanism and the driving mechanism are simultaneously arranged between the housing frame 30 and the panel 10, and both of the driven mechanism and the driving mechanism operate simultaneously. In operation, the driving mechanism drives the panel 10 to move, so that the panel 10 is separated from the housing frame 30. Then, the follower mechanism adjusts the movement of the panel 10 into a lifting movement and a turning movement, so that the movement of the panel 10 is more stable and reliable, and a predetermined effect of driving the panel 10 to lift and turn is achieved.

At this time, the horizontal component force of the panel 10 caused by the driving mechanism will gradually decrease with the angle of the panel 10. When the panel 10 is turned to be vertical, the horizontal component of the force applied to the panel 10 by the driving mechanism will disappear due to the hinge action of the panel 10 and the connecting arm 70, and the panel 10 will only bear the vertical force, thereby performing the lifting motion. Therefore, the driven mechanism can achieve the motion effect of driving the panel 10 to turn and lift.
