A flexible curve type filter element comprises a filter block, the filter block is formed by folding filter paper, the two ends of the filter block are bonded with end frames through polyolefin hot melt adhesive respectively, the side faces of the end frames are attached to the end faces of the filter block, each end frame comprises a folded edge, and the lower surface of each folded edge is attached to the upper surface of the filter block. Needle-punched non-woven fabric side frames are adhered to the two sides of the filter block through hot-melt pressure-sensitive adhesives respectively, and the side faces of the needle-punched non-woven fabric side frames are attached to the side faces of the filter block. The needle-punched non-woven fabric side frame is made of needle-punched non-woven fabric materials and has elasticity, and the needle-punched non-woven fabric side frame and the shell are assembled in an interference mode, so that sealing is achieved. The needle-punched non-woven fabric side frame and the hot-melt pressure-sensitive adhesive have elasticity, the needle-punched non-woven fabric side frame can be bent and folded, and the needle-punched non-woven fabric side frame has a memory attribute after being bent, so that the filter element can be bent into various different angles and shapes according to the inner cavity of the shell.

    一种柔性曲线型滤芯,包括滤块,滤块由滤纸折叠构成,滤块的两端分别通过聚烯烃热熔胶粘接有端部边框,端部边框侧面与滤块的端面贴合,端部边框包括有折边,折边下表面与滤块上表面贴合,滤块的两侧分别通过热熔压敏胶粘接有针刺无纺布侧边框,针刺无纺布侧边框的侧面与滤块的侧面贴合。针刺无纺布侧边框由针刺无纺布材料构成,具有弹性,针刺无纺布侧边框与壳体过盈装配,从而实现密封。针刺无纺布侧边框、热熔压敏胶具有弹性,针刺无纺布侧边框可弯曲、可折叠,针刺无纺布侧边框弯曲后具有记忆属性,使得滤芯能够根据壳体的内腔弯折成各种不同的角度和形状。
