In the present application, the left-right direction, the up-down direction, and the front-back direction refer to the direction in which the range hood is installed above the range and the user is under the user's view angle when facing the range hood.

As shown in fig. 1 and 2, a smoking mechanism according to an embodiment of the present invention includes: a smoke suction hood 100, a first baffle 200 and a second baffle 300, the smoke suction hood 100 having an open end, the first baffle 200 and the second baffle 300 being mounted to the open end; the first barrier 200 and the second barrier 300 are spaced apart from each other in a direction perpendicular to the first barrier 200 to form a smoke inlet space therebetween for the oil smoke to pass through.

Specifically, the first baffle 200 and the second baffle 300 are both located within the smoke suction hood 100 and are distributed in the left-right direction shown in fig. 1. The first baffle 200 and the second baffle 300 are both rectangular, and the length direction of the first baffle 200 and the length direction of the second baffle 300 are both arranged along the front-rear direction of the smoke suction hood 100.
