Problems solved by technology

[0002] Most of the existing range fume fans are composed of a fan and an outer cover. Although this structure can play a protective role when the outer cover is covered, the outer cover must be opened when the fan is running. After the fan is used up, sometimes If you forget to close the outer cover, mice can enter the room through the fan, so the protection performance is poor
