The invention discloses a mixer structure with an adjustable internal and external culvert area ratio, which is characterized in that a mixer adjusting sheet is hinged on an internal casing of a mixer, and the mixer adjusting sheet is driven to rotate through a connecting rod of a driving mechanism to realize autonomous stepless adjustment of the internal and external culvert area ratio; the driving mechanism comprises an actuating cylinder arranged on an inner casing of the mixer, the actuating cylinder is connected with an actuating ring, the actuating ring is connected with a connecting rod through matching of a second pin shaft and a second bushing, and the connecting rod is connected with a driving mixer adjusting sheet; the actuating cylinder pushes the actuating ring to axially move, and the axial movement of the actuating ring drives the connecting rod to do angular movement, so that the mixer adjusting sheet is driven to rotate. The internal and external culvert area ratio of the device is autonomous
