[0003] However, the existing dust removal filter element has a significant problem, that is, the disassembly and cleaning or replacement of the filter structure is extremely inconvenient. The filter structure of the traditional dust removal filter element is usually fixed to the filter element body by a relatively complex fixing method, such as integrated molding or tedious screw fastening. When the filter structure accumulates a large amount of dust and needs to be cleaned, the operator often needs to use various professional tools, and it takes a lot of time and effort to disassemble it. Not only is the efficiency low, but also the other parts of the filter element are easily damaged during disassembly. If the filter structure needs to be replaced due to its service life, the difficult disassembly process will increase the maintenance cost and equipment downtime. For some production environments with extremely high requirements for air quality, the long downtime of the equipment for filter element maintenance will seriously affect the production progress and product quality. In view of this, we propose a dust removal filter element. SUMMARY
