Abstract (en)

[origin: WO2022021595A1] An air duct assembly and a mobile air conditioner. The air duct assembly comprises a first air duct (100) and a second air duct (200); the second air duct (200) is sleeved at the outer side of the first air duct (100), so that a first air channel (110) is formed in the first air duct (100), and a second air channel (210) is formed between the first air duct (100) and the second air duct (200); the first air duct (100) can be individually stretched and extends outside the second air duct (200), so that the first air channel (110) and the second air channel (210) can be communicated with the outdoor environment at the same time, thereby implementing air introduction and exhausting between the two air ducts and the outdoor environment; or, the first air channel (110) is communicated with the outdoor environment, and the second air channel (210) is communicated with the indoor environment, thereby introducing air from the indoor environment and exhausting the air to the outdoor environment.
