The range hood has become one of indispensable kitchen appliances in modern families, utilizes the fluid dynamics principle to work, inhales and exhausts oil smoke through a centrifugal fan arranged in the range hood, and uses a filter screen to filter partial grease particles. The centrifugal fan comprises a volute, an impeller arranged in the volute and a motor driving the impeller to rotate. When the impeller rotates, negative pressure suction is generated in the center of the fan, oil smoke below the range hood is sucked into the fan, accelerated by the fan and then collected and guided by the volute to be discharged out of a room.

In the process of exhausting the oil fume flow, most of grease can be separated out, so an oil collecting cup is often installed at the bottom of a fume collecting hood of the range hood to collect the separated grease, and the grease is disposed when a certain amount of grease is reached. In the prior art, most oil collecting cups can only be observed by naked eyes to distinguish whether the oil collecting cups are full of oil stains. However, with the pace of life increasing, people often forget to clean the oil collecting cup, which easily causes the oil stains in the oil collecting cup to seep out, and further causes secondary pollution to the environment in the kitchen.
