Abstract (en)
[origin: EP3926250A1] The present application relates to an air outlet mechanism and an air treatment device. The air treatment device is provided with a vertical air duct. A first upper end surface of the vertical air duct is obliquely arranged. The air outlet mechanism includes a first air outlet plate and a second air outlet plate. The first air outlet plate surrounds a higher side of the first upper end surface and is rotatably connected to the air treatment device. The second air outlet plate surrounds other parts of the first upper end surface and is connected to the air treatment device. The first air outlet plate includes a straight plate rotatably connected to the air treatment device and an arc-shaped plate connected to the straight plate. An end of the second air outlet plate away from the first upper end surface is inclined toward an outer side of the air duct. An air outlet is formed between the first air outlet plate and the second air outlet plate. The air outlet is capable of being adjusted by rotating the first air outlet plate. The rotation of the first air outlet plate can adjust the shape, size and air flow direction of the air outlet, increasing the flexibility and controllability of the air output, which is easy to control and achieve satisfactory air supply volume and air blow-down effect, and eliminates the dead corners of the air supply. The air outlet mechanism has high integrity, and can be conveniently produced and easily assembled.
