description	The invention relates to a ceiling extractor hood. The ceiling extractor hood comprises an exhaust fume collecting hood, a first rectification plate and a second rectification plate, wherein first and second air inlet passages are respectively formed between the first and second rectification plates and the inner cavity wall of the exhaust fume collecting hood; the first and second rectification plates are rotatably arranged on both sides of a mounting shaft; first and second driving mechanisms respectively drive the first and second rectification plates to rotate so as to adjust the area of the air inlets of the two air inlet passages; first and second temperature sensors capable of sensing the temperature of two air inlets are mounted on the exhaust fume collecting hood; the first and second driving mechanisms correspondingly drive the first rectification plate and the second rectification plate according to the temperature difference of the air inlets on both sides so that the area of the air inlet is matched with the temperature of the air inlet on the same side. The ceiling extractor hood has the advantages that the heating status of both sides is judged by sensing the distribution of temperature fields on the left and right sides by two temperature sensors, the possible direction of large and small smoke is prejudged, and the distribution of left and right negative pressure areas is adjusted by adjusting the area of the left and right air inlets by two driving mechanisms so as to improve the exhaust fume collecting effect.
