Air purifier

Abstract

The invention discloses an air purifier which comprises a purifier body and a barrel-shaped filter element, wherein the purifier body is provided with an air purification cavity for containing the filter element; furthermore, the air purifier further comprises a filter element mounting and fixing device which is arranged in the air purification cavity and is used for mounting and fixing the filter element; the filter element mounting and fixing device consists of a lifting disk fixing frame, a lifting disk, a knob and a base which are connected in sequence from top to bottom; a hole from which the lifting disk extends out is formed in the lifting disk fixing frame; the knob is arranged on the base in a rotatable manner; the upper end of the knob supports the lifting disk and drives the lifting disk to do reciprocating movement in the direction perpendicular to the base; and therefore, the filter element is easy to dismount and mount; meanwhile, damage to the filter element filter element dismounting and mounting processes can be avoided; the filter purification effect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of purification equipment, in particular to an air purifier. Background technique [0002] With the aggravation of the air pollution problem, more and more air purifiers are used. Most of the air purifiers on the market use filter screens or filter elements for their purification components, and the installation structures of different forms of purification components are also different. For air purifiers that use the filter element as the purification component, the installation structure of the filter element is mostly simple, and the fixing effect is poor. In order to make the disassembly and installation of the filter element easier, a space between the upper end of the filter element and the cavity for accommodating the filter element needs to be reserved. There is a large gap. During the working process of the air purifier, the air that has not been filtered and purified by the filter element is easy t...

Problems solved by technology

For air purifiers that use the filter element as the purification component, the installation structure of the filter element is mostly simple, and the fixing effect is poor. In order to make the disassembly and installation of the filter element easier, a space between the upper end of the filter element and the cavity for accommodating the filter element needs to be reserved. There is a large gap. During the working process of the air purifier, the air that has not been filtered and purified by the filter element is easy to flow into the air purifier from the upper end of the filter element and sent out, which reduces the filtering and purification effect of the air purifier; and for the filter element installation structure More complex air purifiers, although the fixing effect is better, but there are disadvantages such as inconvenient disassembly and assembly operations, and easy damage to the filter element.
