Description

Technical Field

[0001] The invention relates to the technical field of cartridge air purifiers, and in particular to a cartridge air purifier which is convenient for replacing a filter element. Background Art

[0002] A cartridge air purifier is an air purification device that uses a cartridge as a filter element. This type of air purifier intercepts, separates and removes harmful substances such as particulate matter, dust, pollen, bacteria, viruses, etc. in the air through the filtering effect of the cartridge, thereby achieving the purpose of purifying the air.

[0003] The working principle of existing cartridge air purifiers can be summarized into three main steps: filtration, dust accumulation and cleaning. First, when polluted air enters the air purifier through the filter cartridge, the solid particles in the air will be intercepted by the filter cartridge and attached to the surface of the filter cartridge. As time goes by, a layer of dust will form on the surface of the filter cartridge. These dust particles need to be removed regularly to ensure the filtering effect of the air purifier. The cleaning system can use mechanical vibration, gas backblowing and other methods to remove the dust layer and restore the filtering function of the filter cartridge.

[0004] The outer shells of most existing cartridge air purifiers are fixed by clips or screws. Therefore, the disassembly and assembly of the cartridge air purifier requires the use of tools such as screwdrivers to remove the cover or screw cap on the side of the filter, and then take out the filter cartridge before filtering and cleaning the filter cartridge or replacing it with a new one.

[0005] Therefore, based on the above actual situation, several defects of the existing cartridge air purifier are summarized:

[0006] 1: The shell of most cartridge air purifiers is not easy to disassemble, which makes it difficult to remove the filter element in the cartridge, resulting in inconvenience in cleaning, maintenance and replacement;

[0007] 2: Existing cartridge air purifiers cannot actively clean the filter element in the cartridge, but need to be operated by external equipment, which increases the difficulty of cleaning;

[0008] 3: Most of the filter cartridges in the cartridge air purifier are cylindrical, and the structures for installing and fixing the cylindrical filter cartridges are mostly fixed with screws. This fixing method not only requires the gradual disassembly of the outer shell of the cartridge air purifier, but also the continued disassembly of the filter cartridge inside the cartridge air purifier, resulting in cumbersome disassembly and assembly, and it is inconvenient for users to replace the filter element in the cartridge independently.

[0009] For this reason, we propose a cartridge air purifier that is easy to replace the filter element. Summary of the invention
