Description

Technical Field

[0001] This utility model relates to a filter structure, specifically to a detachable and washable air purifier filter structure. Background Technology

[0002] Air purifiers have become essential appliances in many homes and offices. Their core function relies on filters. Currently, most air purifiers on the market use composite filters, which integrate multiple layers of filtration materials such as pre-filters, HEPA filters, and activated carbon filters into an inseparable whole.

[0003] Because the filter layers are firmly bonded or sealed together, users cannot disassemble the filter assembly. When a large amount of visible contaminants such as hair and dust accumulates on the filter surface, or when the activated carbon layer becomes saturated, users cannot effectively clean or maintain specific parts. The usual practice is to replace the entire filter assembly, which is not only cumbersome but also wastes resources and increases operating costs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a detachable and washable air purifier filter structure to solve the problems existing in the background art.

[0005] The removable and washable air purifier filter structure of this utility model is achieved through the following technical solution, including a filter element body, which includes a fixing seat, an activated carbon fiber filter element arranged in a ring, and a filter assembly;

[0006] The activated carbon fiber filter element is inserted into the fixing cavity of the fixing base and fixed by a magnetic attraction structure;

[0007] The filter assembly is fixed to the base from top to bottom, with the outer layer of the double filter placed on the outside of the base and the inner layer of the filter assembly placed on the inside of the base.

[0008] As a preferred technical solution, the fixing base includes an upper fixing ring and a lower fixing ring, and the upper fixing ring and the lower fixing ring are connected by a connecting post.

[0009] As a preferred technical solution, the connecting column is provided with a clearance groove, and the filter assembly is provided with a plug-in block corresponding to the clearance groove. The filter assembly is plugged into the fixing base through the clearance groove and the plug-in block, and is attracted and fixed by a magnetic structure.

[0010] As a preferred technical solution, the central hollow of the upper and lower fixing rings forms an installation position, and the activated carbon fiber filter element is placed on the installation position and adsorbed by the magnetic attraction structure at the connecting column, thereby realizing the fixation of the activated carbon limiting filter element.

[0011] As a preferred technical solution, the magnetic suction structure includes a magnet disposed on the connecting column, and metal parts are disposed on both sides of the activated carbon fiber filter element and on the insertion block of the filter screen assembly, thereby realizing the fixation of the activated carbon fiber filter element and the filter screen assembly on the fixing base.

[0012] As a preferred technical solution, the filter assembly includes an outer breathable mesh and an inner filter mesh, and the outer breathable mesh and the inner filter mesh are connected by a connecting piece.

[0013] The plug-in block is disposed on the outer breathable mesh to facilitate the fixation between the filter assembly and the mounting base.

[0014] As a preferred technical solution, the outer breathable mesh is provided with breathable mesh holes, and the inner filter mesh is provided with filter mesh holes.

[0015] The beneficial effects of this utility model are:

[0016] The filter element of this utility model adopts a split structure. The activated carbon fiber filter element and the filter screen assembly can be removed from the fixed base independently and quickly, which greatly facilitates the thorough cleaning or replacement of each part and solves the problem of inconvenient cleaning of traditional integrated filter screens.

[0017] This invention uses a magnetic attraction structure composed of magnets and metal parts for fixation, which can be installed and disassembled without tools. The assembly method is very simple and quick, and the user experience is good.

[0018] The filter assembly of this invention adopts a double-layer design with an outer breathable mesh and an inner filter mesh, which works in conjunction with the annular activated carbon fiber filter element to form a multi-layer, high-efficiency filtration system, significantly improving the air purification effect.
