Problems solved by technology
The place where the air purifier is used is indoors. Users have higher requirements on the noise of the air purifier. At the same time, because the air purifier has multi-layer filters, it has a great impact on the air intake.
[0003] Existing air purifiers use centrifugal fans, and the overall structure of the centrifugal air duct adopts an involute design. The resistance capacity of the air duct is poor, the air output is small, and it will generate relatively loud noise.

Abstract
The invention provides an air flue structure and an air treatment device. The air flue structure comprises a volute, the volute comprises a volute-shaped portion (1) and air outlet portions connected to the two ends of the volute-shaped portion (1), the volute-shaped portion (1) is provided with an installing cavity (2) used for installing a fan blade (25), the volute-shaped portion (1) comprises a first concave portion concaved in the direction of being far away from the installing cavity (2), the first concave portion comprises a first circular arc section (3), and the circle center of the first circular arc section (3) is located at the central axis of the fan blade (25). According to the air flue structure, the anti-resistance capability of an air flue can be enhanced, the air outlet volume is increased, and air outlet noise is reduced.
Description
technical field [0001] The application belongs to the technical field of air conditioning, and in particular relates to an air duct structure and an air treatment device. Background technique [0002] With the improvement of people's living standards, the use of air purifiers in modern families is becoming more and more common. The place where the air purifier is used is indoors, and users have higher requirements on the noise of the air purifier. At the same time, because the air purifier has multi-layer filters, it has a great impact on the air intake. [0003] Existing air purifiers use a centrifugal fan, and the overall structure of the centrifugal air duct adopts an involute design. The resistance of the air duct is relatively poor, the air output is small, and it will generate relatively loud noise. Contents of the invention [0004] Therefore, the technical problem to be solved in the present application is to provide an air duct structure and an air handling devic...
