The invention relates to a grilling oil mesh with an adjustable air suction inlet for a range hood. The grilling oil mesh is arranged at a cooking fume suction inlet of the range hood or at an optional position from the cooking fume suction inlet to a volute air inlet of the range hood. The grilling oil mesh comprises an outer frame, an outer frame body is provided with a plurality of rotating holes opposite in position, a plurality of sheets are arranged in the outer frame body, and rotating shafts inserted into the rotating holes in the outer frame are arranged at two ends of the sheets. The grilling oil mesh has the advantages that the air suction inlet of the grilling oil mesh can be directed at cooking fume dispersed around by means of direction adjustment of the sheets, capability of catching the cooking fume before an operator is improved, the cooking fume is sucked into a range hood body to the greatest degree, possibility that the cooking fume escapes forwards can be lowered greatly, and thereby direct effect on human health is mitigated remarkably; when being used for a two-burner kitchen range, the grilling oil mesh can achieve the largest cooking fume suction performance by adjusting directions of oil mesh sheets above each burner separately to allocate air suction effects of the oil mesh above the two burners reasonably.
