Air purifier and its filter module

Abstract

The invention provides an air purifier and a filtering module thereof. The filtering module of the air purifier comprises a filter shell and a cover plate, wherein the filter shell comprises a peripheral wall and a side wall perpendicularly arranged at one end of the peripheral wall, and a concave filter accommodating cavity is defined by the peripheral wall and the side wall; the side wall is provided with a first hollowed-out part for allowing air to flow through, and the filter accommodating cavity is used for installing an air filter so that the air coming from the first hollowed-out part can be filtered; the cover plate is detachably arranged at the other end, opposite to the side wall, of the peripheral wall so that the filter accommodating cavity can be covered; the cover plate is provided with a second hollowed-out part for allowing air to flow through so that the filtered air can be exhausted through an external draught fan; and at least one elastic clamping block is arranged in the filter accommodating cavity and arranged on the peripheral wall in a telescopic mode towards the interior of the filter accommodating cavity so that the air filter can be fixed into the filter accommodating cavity. By means of the scheme, the using convenience of the air purifier is improved.
