The air entering the detection air hole 16 is the air above the telescopic panel 1. When the air curtain assembly is started and the smoke exhaust fan of the range hood is started, the air quality above the telescopic panel 1 represents the purification of the oil fume by the range hood and the escape of the oil fume. When the result detected by the PM2.5 detection module meets the standard, it indicates that there is no oil fume escape. When the result detected by the PM2.5 detection module does not meet the standard, it indicates that there is oil fume escape.
