[0002] The automatic cleaning device of the range hood is an intelligent device designed to solve the problem of grease accumulation in traditional range hoods after a period of use. These devices use advanced technologies such as sensors, automatic control systems and cleaning devices to automatically monitor the grease level of the range hood and clean it to ensure the efficient operation of the range hood.

[0003] In current technology, range hoods often use high-power silent fans to suck the grease generated during cooking into the device through the air inlet box and discharge it through the exhaust pipe. After the range hood has been used for a long time, a thick layer of dirt will adhere to the fan blades of the exhaust fan. This will inevitably affect the air suction effect of the fan in the long run. At the same time, it is more troublesome to disassemble the equipment for cleaning, and the price is also more expensive.

[0004] Therefore, an automatic cleaning device for a range hood is proposed. Utility Model Content
