Abstract
The present invention provides an air purifier which includes an outer case () having a filtering cavity () and a driving cavity () space apart from each other, a filter () received in the filtering cavity (), a driving fan () received in the driving cavity (). The outer case has at least one air inlet () and an air output arrangement (). The air purifier further includes an air hub () provided between the filtering cavity () and the driving cavity (). The air hub () includes a first air drawing frame () and a second air drawing frame (). The first air drawing frame () extending within a central cavity () of the filter () and is coaxially formed with respect to the filter (). An axial direction of the first air drawing frame () is aligned with a longitudinal axis of the driving fan (). The second air drawing frame () peripherally, upwardly and radially extends from the first air drawing frame () toward an upper end of the filter (). The first air drawing frame () and a second air drawing frame () increase total surface area for air flow and reduces air resistance and noise.
