[0019] The utility model will be further described in detail below with reference to the drawings. A range hood with a liftable smoke suction port comprises a shell 1, an installation cavity 11 is formed in the shell 1, a fan device is arranged in the installation cavity 11, an air outlet of the fan device is communicated with the outside through an air outlet pipe 2, an air inlet of the fan device is communicated with the installation cavity 11, a guide hole 12 is formed in the bottom of the installation cavity 11, a smoke collecting box 3 is liftable arranged in the guide hole 12 through a lifting mechanism 4, the smoke collecting box 3 is provided with a smoke suction port 31, the smoke suction port 31 is communicated with the fan device through the smoke collecting box 3.
[0020] The lifting mechanism 4 includes movable rails 41 mounted on both sides of the back of the smoke collecting box 3, and the fixed rails 42 are fixedly installed on the inner wall of the shell 1 correspondingly;
[0021] The driving mechanism 43 is installed between the smoke collecting box 3 and the mounting cavity 11, and the smoke collecting box 3 slides along the fixed rails 42 under the action of the driving mechanism 43 to realize the lifting movement of the smoke collecting box 3 in the guide hole 12.
[0022] The back of the smoke collecting box 3 is provided with a mounting groove 33, and the movable rails 41 are embedded in the mounting groove 33.
[0023] The middle of the back of the smoke collecting box 3 is provided with a driving groove 34, and the driving mechanism 43 is installed in the driving groove 34.
