[0028] Specifically, an air inlet port 10 and an air outlet port 11 are distributed inside the air outlet shell 1. Two independent air outlet channels are designed inside the air outlet port 11, namely a first air outlet channel 100 and a second air outlet channel 101. Both channels are directly connected to the air inlet port 10 to facilitate smooth air flow in and out. In this embodiment, the core component of the damper structure is the air guide component 2, which consists of a main damper 20 and an auxiliary damper 21. Both the main damper 20 and the auxiliary damper 21 can be rotatably connected to the air outlet shell 1 around their respective axes, and their positions are exactly between the air inlet port 10 and the air outlet port 11. The main damper 20 is connected to an external drive device through a spline shaft 200, and a driving gear 201 is installed on the spline shaft 200. At the same time, the auxiliary damper 21 is equipped with a driven gear 202, and the driving gear 201 and the driven gear 202 can be dynamically engaged. When the motor drives the spline shaft 200 to rotate, it can drive the main damper 20 to swing up and down, thereby realizing the switch control of the first air outlet channel 100 or the second air outlet channel 101. The main damper 20 has two specific positions (the first position and the second position) on the air outlet housing 1. In these two positions, the main damper 20 will close the first air outlet channel 100. When the main damper 20 switches between the first position and the second position, it will cause the driving gear 201 to mesh with the driven gear 202, thereby driving the auxiliary damper 21 to rotate on the air outlet housing 1, thereby controlling the switch state of the second air outlet channel 101. Specifically, when the main damper 20 is in the first position, the first air outlet channel 100 is closed, and the second air outlet channel 101 is opened; when the main damper 20 is turned to the second position, both air outlet channels are closed.

[0034] The air outlet shell 1 is specially provided with a wind shield 102 and a first air door limit portion 103, and a track groove 104 formed therebetween serves to guide the movement path of the main air door 20. The main air door 20 can stick to the wind shield 102 and slide in the track groove 104 until it contacts and stops with the first air door limit portion 103.

[0035] It is worth mentioning that in order to improve the sealing performance, a flexible material such as rubber may be provided on the track groove or the main air door.
