A deflector rod includes a linkage member configured to drive a louver of an air outlet frame to rotate and a shift member connected with the end of the linkage member. The linkage member includes a first limiting projection provided at one end of the linkage member. The shift member includes a groove extending between two opposite ends of the shift member and a second limiting projection provided at a side wall of the groove away from the linkage member. Both the second limiting projection and the first limiting projection are spaced apart from a bottom wall of the groove. The groove, the first limiting projection, and the second limiting projection are configured to clamp an air guide bar of the air outlet frame such that the air guide bar is at least partially located in the groove, between the second limiting projection and the bottom wall of the groove, and between the first limiting projection and the bottom wall of the groove.
