Claim 2:
3. The air outflow device according to claim 1, wherein the second driving member is a second electric motor, a connecting column is fixedly connected to an output portion of the second electric motor, a first protrusion and a second protrusion are formed on the connecting column, a column sleeve is fitted over the connecting column, a first helical groove and a second helical groove respectively corresponding to the first protrusion and the second protrusion are formed on the column sleeve, the first helical groove and the second helical groove have the same helical direction, and a first transmission rod and a second transmission rod are further fixed to the column sleeve; the first transmission rod is connected to the first louver structure by means of a first transmission assembly, and the second transmission rod is connected to the second louver structure by means of a second transmission assembly; a third sliding structure is disposed on the column sleeve, a fourth sliding structure slidably connected to the third sliding structure is further disposed in the shell, and the third sliding structure and the fourth sliding structure are relatively slidable only in an axial direction of the column sleeve;
the second electric motor is capable of driving the column sleeve to rotate such that the first protrusion and the second protrusion respectively slide in the first helical groove and the second helical groove, the column sleeve moves in the axial direction, the first transmission rod and the second transmission rod then both move in the axial direction, and the first transmission assembly and the second transmission assembly are moved to drive the first louver structure and the second louver structure to swing together in the same direction.
