Air duct structure of air purifier

Abstract

The invention discloses an air duct structure of an air purifier. The air duct structure of the air purifier comprises a shell body, wherein the shell body comprises an air inlet cavity, a purification cavity, a buffer area, a fan cavity and an air outlet which are sequentially arranged from bottom to top, the opening diameter of the bottom of the air inlet cavity is larger than the opening diameter of the bottom of the purification cavity, the opening diameter of the top of the purification cavity is larger than the opening diameter of the buffer area, the opening diameter of the bottom of the buffer area is larger than the diameter of an inner circle of the fan cavity, the diameter of the inner circle of the fan cavity is larger than the opening diameter of the air outlet, and wall bodies on the two sides of the air outlet are inwards chamfered. According to the air duct structure of the air purifier, the shell body as well as the air inlet cavity, the purification cavity, the bufferarea, the fan cavity and the air outlet of the shell body are arranged and formed so that the air inlet amount of the air purifier can be effectively improved, and the air purification efficiency isimproved; and in addition, the air outlet speed of the air outlet is increased, the circulation speed of indoor air is increased, and the problems that a traditional air duct structure of an air purifier is small in air inlet amount and low in air outlet speed are solved.

Description

technical field [0001] The invention relates to the technical field of purifiers, in particular to an air duct structure of an air purifier. Background technique [0002] Air purifiers generally have wall-mounted, hanging, ceiling-mounted and floor-standing types. According to air purification technology, they are divided into: HEPA air purifier, activated carbon air purifier, electronic air purifier, ultraviolet air purifier, Clean room air purifier, negative ion air purifier, ion wind air purifier, art air purifier, ozone air purifier, etc. [0003] At present, activated carbon air purifiers in household air purifiers have been widely used in people's lives. The existing air purifiers are mostly divided into regular tubes, and the suction rate of the air inlet is the same as that of the air outlet. The disadvantage of this air duct structure is that the air intake volume is small and the air output speed is relatively slow. Contents of the invention [0004] The purpos...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an air duct structure for an air purifier, which has the advantages of large air intake and fast air discharge rate, and solves the problems of small air intake and slow air discharge rate in the air duct structure of traditional air purifiers
