The waste gas generated in industrial production affects the living environment, and air purifiers are born for this purpose.

[0003] In the prior art, most air purifiers are composite types, that is, multiple purification technologies and material media are used at the same time. Due to the particularity of product use, regardless of day or night, it should not affect normal work and rest. Therefore, in addition to the purification effect, the noise of the product is also a concern for everyone. In response to the above problems, the literature with the application number 201420606544.8 discloses a structure of an air purifier for reducing noise, which includes a housing and an air duct. The air duct is located inside the housing; the air duct is composed of an air inlet part and an air outlet part connected. A motor is arranged in the air inlet part, and the rotating shaft of the motor is connected with a wind wheel; the air duct is made of foam plastic, and an attached film layer is arranged on the inner surface of the air duct. Compared with the prior art, this structure has a low cost, and has an attached film layer, the inner surface is smooth, and the noise is small when air passes through.
