Fuhai's experience, first of all, the smoke exhaust pipe should be installed in the middle of the hood, so as to facilitate the smoke from the stove under the hood. If there is a steaming cabinet under the hood at the same time, the butt joint position of the fume exhaust pipeline and the hood will be close to the stove section.

The opening of the air inlet closest to the smoke exhaust nozzle is smaller, on the contrary, the air inlet farther away from the smoke exhaust nozzle should be larger, which can realize uniform smoke exhaust, because the closer to the pipe mouth, the stronger the suction.
