Problems solved by technology

[0002] Existing air purifiers also have certain defects in the use process: In the air duct design, if you want to increase the CADR value of the air purifier, you need a large air intake and a large air output, which will cause the air to collide in the air duct. The noise of the inner cavity parts is relatively large, which affects its use effect

Abstract

The invention discloses an air purifier which comprises a case, a fan assembly and a filter element. A wind inlet and a wind outlet are formed in the case, the wind inlet is formed in the lower portion of a side surface of the case, and the wind outlet is formed in the upper portion of the case; the filter element is internally arranged at the bottom of the case, the tubular outer contour of the filter element is matched with the edges of the inner wall of the lower portion of the case, an exhaust channel which is positioned inside the filter element is formed in the filter element, an exhaust outlet is formed in the upper end of the exhaust channel, and a wind inlet side surface is arranged on at least one part of the outer peripheral surface of the filter element and is close to the wind inlet; the fan assembly is internally arranged on the upper portion of the case and is used for delivering air exhausted from the exhaust outlet to the wind outlet. According to the technical scheme, the air purifier has the advantage that noise can be prevented from being increased under the condition that high CADR (clean air delivery rate) values are guaranteed.

Description

technical field [0001] The invention relates to the technical field of purification, in particular to an air purifier. Background technique [0002] Existing air purifiers also have certain defects in the use process: In the air duct design, if you want to increase the CADR value of the air purifier, you need a large air intake and a large air output, which will cause the air to collide in the air duct. The noise of the inner cavity parts is relatively large, which affects its use effect. Therefore, the CADR value of the air purifier is proportional to the noise. Contents of the invention [0003] The main purpose of the present invention is to provide an air purifier aiming at ensuring high CADR value without increasing noise. [0004] In order to achieve the above object, the air purifier proposed by the present invention, the air purifier comprises: [0005] A casing, the casing is provided with an air inlet located at the lower part of its side and an air outlet loc...
