Specifically, the case 440 may function to protect the gear 420 and the rack 430, and may prevent the gear 420 and the rack 430 from being damaged by collision. In addition, the box 440 can prevent sundries from entering between the gear teeth of the gear 420 and the rack 430 to affect the transmission between the gear 420 and the rack 430. The motor 410 may be coupled to a gear 420. For example, the gear 420 may be splined to the output shaft of the motor 410, and the gear 420 may be meshed with the rack 430. When the motor 410 is operated in the forward direction, the motor 410 can drive the gear 420 to rotate in the forward direction, the rack 430 can be driven to move in the forward direction when the gear 420 rotates, the rack 430 can further drive the connecting piece 30 to move, and the switch door 20 can move along with the connecting piece 30 to open the air outlet 110; when the motor 410 is operated in the reverse direction, the motor 410 can drive the gear 420 to rotate in the reverse direction, the gear 420 can drive the rack 430 to move in the reverse direction, and the door 20 can be driven to close the air outlet 110 through the connecting piece 30.

As shown in fig. 14, the rack 430 may be provided with a fitting 431 extending from the case 440, the case 440 may be provided with a first track passage 441, and the fitting 431 may be movably coupled to the first track passage 441 and connected to the connection member 30. When the rack 430 moves, the connecting member 30 can be driven to move synchronously by the fitting 431. Thus, with the above arrangement, the moving track of the fitting 431 can be defined by the first track passage 441, so that the stability and smoothness of the movement of the rack 430 and the link 30 are improved, and further, the movement of the opening and closing door 20 can be made more stable, and the accuracy of the moving track of the opening and closing door 20 is improved.

In the specific example shown in fig. 14, the case 440 includes an upper cover 440a and a lower cover 440b, and the upper cover 440a and the lower cover 440b are formed in a cavity structure, and the upper cover 440a and the lower cover 440b may be coupled together by a snap-fit manner, thereby defining installation spaces of the gear 420 and the rack 430. The upper cover 440a may be provided with a first track passage 441 penetrating therethrough in the up-down direction, and the rack 430 is provided with a fitting 431 extending in the up-down direction, the fitting 431 being formed in a substantially cylindrical shape.
