AI Technical Summary
Existing V-type filters are fixed with rivets or fasteners during assembly, which is cumbersome and may lead to a decrease in sealing performance. Traditional hot melt adhesive lines are heavy and have limited compressive strength, and are prone to aging and falling off after long-term use, affecting product quality and lifespan.
The self-locking structure of the foamed filter paper is adopted. It is fixed by the compression of the bottom C-groove, side plate, top C-groove and top edge C-groove. Combined with the adhesion between the foam and the filter paper, it achieves self-locking without fasteners. The adhesion and softness of the foam ensure stability and sealing.
It simplifies the assembly process, improves production efficiency and product sealing performance, reduces production costs, ensures that the filter paper does not fall off, enhances compressive strength, adapts to different frame shapes, reduces filter weight, and improves overall quality.
