Abstract

本实用新型公开了一种空气净化器滤芯,它包括内滤芯和外滤芯两部分,分别由上盖、设置在上盖上的密封圈、下盖、护网及过滤材料等组成,其特征在于内、外滤芯的上盖与密封圈;下盖分别采用聚氨酯材料注塑成整体结构,并分别与其相接的护网熔合连接。由于这种结构强度高、弹性好,抗震,耐油水,防腐蚀,密封性能好,能使空气净化器的技术性能长时间保持在最佳状态,因而能显著提高发动机的使用寿命。

Description

一种空气净化器滤芯
本实用新型涉及空气净化技术领域，特别是一种空气净化器滤芯。有空气净化器所使用的滤芯是由薄钢板冲压成型，配以过滤材料制成，部件之间的连接全部采用胶粘剂粘接。由于胶粘剂粘接强度低，抗震性能差，并且易老化，受到潮湿空气会自然脱解，密封失效，从而造成相关部件变形、腐蚀、生锈，导致灰尘直接进入发动机，严重影响发动机的使用寿命。
本实用新型的目的提供一种新的空气净化器滤芯，该滤芯结构强度高，部件连接牢固，密封性能好，并且抗震、耐腐蚀。
本实用的目的是通过以下技术方案实现的：在现有技术的基础上，选用一种弹性好、强度高的工程塑料(如聚氨酯)，用注塑的方法，将空气净化器滤芯的内滤芯的上盖与布置在上盖上的密封圈；下盖；外滤芯的上盖与设置在上盖上的密封圈；下盖分别注塑成整体结构，并与其相接的护网熔合连接即成。
本实用新型内、外滤的上盖与密封圈；下盖分别为整体结构，与护网熔合连接，并采用了高弹性材料，因而结构强度高，密封性能好，抗震、耐油水，防腐蚀，使用寿命长，采用它能使空气净化器技术性能稳定、可靠，空气净化效果好，从而提高了发动机的使用寿命。

图2是外滤芯俯视图；
图3是外滤芯仰视图；
图4是内滤芯剖视图；
图5是内滤芯俯视图；
图6是内滤芯仰视图。
下面结合实施例及附图对本实用新型作进一步描述，如图1、2、3所示的外滤芯，呈圆柱形，中空，由上盖1、设置在上盖的密封圈2、下盖3、内护网4、外护网5，布置于内外护网之间的滤纸6等构成，其中上盖1与密封圈2；下盖3分别采用聚氨脂材料注塑成整体结构，并且上盖1、下盖3分别与内、外护网4、5熔合连接；图4、5、6所示的内滤芯呈园柱形，中空，由上盖7、布置在上盖上的密封圈8、下盖9、护网10、布置在护网10上的毛毡11等构成。其中上盖7与密封圈8；下盖9用聚氨酯分别注塑成为一体结构，并分别与护网10熔合连接。内滤芯密封圈8的上部圆周上设置有凸台12，用以增加滤芯自由转动的阻尼，增强密封效果。使用时，将内、外滤芯组装起来(内滤芯插入外滤芯中)即可。实验证明，采用本实用新型的空气净化器，空气净化质量好，技术性能稳定，发动机使用寿命明显提高。
