The lifting mechanism comprises a gear box and a driving part, a transmission assembly is installed at the power output end of the driving part, and the upper end of a first upper driven connecting rod and the upper end of a second upper driven connecting rod of the transmission assembly are both hinged to an upper box body of the extractor hood. A gear box of the transmission assembly is fixed to the lower box body, and the lower end of a first lower driven connecting rod and the lower end of a second lower driven connecting rod of the transmission assembly are both hinged to the air inlet body. The end portions of an upper driving connecting rod and a lower driving connecting rod of a transmission assembly of the lifting mechanism are provided with gears, the four driving connecting rods are meshed through the gears to achieve synchronous movement, an upper box body of the range hood is connected to an upper driven connecting rod, a lower box body is fixed to a gearbox, and an air inlet body is connected to a lower driven connecting rod. According to the lifting mechanism, two-stage synchronous lifting motion of the upper box body and the air inlet body can be achieved, left-right shaking in the motion process is reduced by restraining motion in the left-right direction, and then the lifting stability of the whole machine is improved.

    一种升降机构及应用有该升降机构的吸油烟机,包括齿轮箱和驱动件,驱动件的动力输出端上安装有传动组件,传动组件的第一上从动连杆的上端和第二上从动连杆的上端均与吸油烟机的上箱体相铰接,传动组件的齿轮箱固定在下箱体上,传动组件的第一下从动连杆的下端和第二下从动连杆的下端均与进风体相铰接。该升降机构的传动组件的上、下驱动连杆端部带有齿轮,四根驱动连杆通过齿轮啮合,实现运动的同步,该吸油烟机的上箱体连接在上从动连杆上,下箱体固定在齿轮箱上,进风体连接在下从动连杆上,可以实现上箱体和进风体的二级同步升降运动,该升降机构通过对左右方向运动的约束,减少了运动过程中左右晃动,进而提高整机升降的稳定性。
