 背景技术
空气净化装置随着日益严重的空气污染已经越来越体现出其对于生活、医疗、生产等等方面的重要性，目前市场上比较流行的空气净化设备均使用平板过滤纸，需过滤空气通过过滤纸的拦截，起到了灰尘细菌等杂质与纯净空气相分离的作用，为了提高空气过滤的效果，一般均采用增厚增密过滤纸的方式，然而这种方式致使风阻增大，出风量减少，空气净化效率降低，净化速度减慢。另外，现有技术中，过滤纸属于需要经常更换的耗材，过滤纸往往与电网一体成型，在电路连接方面需要很高标准，从而保证使用过程中不发生漏电，而作为耗材，这些高标准反而造成了成本的上升，使用者的使用成本增高的同时也使普通消费者对空气过滤设备望而却步。

 本发明的实施方式
为了使本实用新型的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本实用新型进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本实用新型，并不用于限定本实用新型。
参照图1至图3、图7和图8所示， 本实用新型提供一种过滤装置，包括具有至少一个折弯部的过滤纸1，以及可容纳所述过滤纸的外框2，所述过滤纸1的横截面形状呈“M”形或者 “N”形或者倒“V”形或者上述形状的连续延伸，所述过滤纸1上外表面设有上放电网3，所述上放电网3随着所述过滤纸1的起伏铺设，所述过滤纸1下方两个波谷11底部之间的空间设有放电丝4，所述放电丝4下方设有平板式下放电网5，所述上放电网3与所述下放电网5电连接。依借上述技术方案，本实用新型所提供的过滤装置中过滤纸1具有至少一个折弯部，而过滤纸1折弯部的设计增加了过滤纸1的表面积，空气净化设备的风机将需过滤空气吹向过滤纸1之时，由于过滤纸1增大了表面积也就同时增大了空气通过量，从而提高了空气净化设备的空气过滤净化效率，所述上放电网3与下放电网5通过电连接后可与所述放电丝4在工作中形成高压电场，对于通过高压电场的空气中所蕴含的病毒及有害成分进行电解杀灭。
在实际生产过程中，所述上放电网3随着所述过滤纸1的起伏分版铺设,然后进行电连接，这样设计的目的在于，所述上放电网3的生产成本会大幅降低，亦或者，将所述上放电网3一体成型扣在所述过滤纸1上表面，当然了，一体成型的上放电网3生产成本一定会高，但组装效率会大幅提高，故此本实施例采用一体成型的上放电网3。
从图1来看，所述放电丝4垂直于所述过滤纸1两内表面13的连线所形成的夹角度数是a，所述a是7度到90度之间任意数值，所述放电丝到所述过滤纸波峰内顶点12的连线与所述过滤纸两内表面13所形成的夹角是b1和b2，所述b1和b2度数相同，其度数是3.5度到45度之间任意数值。
经过反复试验，本实施例采用：所述a的优选角度是15度，所述b1和b2的优选角度是7.5度，这样的角度设计会充分发挥电场效率。
优选地，所述过滤纸1下内表面设有感应片6，所述感应片6随所述过滤纸1下表面起伏铺设。所述感应片6随着所述过滤纸1下表面的起伏分版铺设,或者所述感应片6一体成型贴在所述过滤纸1下表面，需要注意的是，分版铺设的情况下，所述感应片6各个分版之间不需要电连接，而所述感应片6所起的作用实际上是将所述放电丝4所放出的高压电通过感应片6传递到远端接近顶点12的位置，以便使高压电能够更加均匀的与上放电网3进行反应，避免了在顶点12附近留有死角或者说是细菌、病毒逃避空间。
具体安装方式，可以采用了两种方式，第一，所述放电丝4纵向安装于所述外框2下边缘，所述放电丝4的长度小于所述外框2的纵向长度。第二，所述放电丝纵4向安装于净化机内与所述过滤装置相对应的位置，所述外框2相对于所述放电丝4经过的位置设有缺口。上述两种方式各有优点，第一种是放电丝4与外框2之间的位置关系更为稳固，不易产生位置偏移，整体更换维护方便，而第二种方式在维护过程中取出外框2及内部过滤纸1等部件时，不会碰动或接触到所述放电丝4，减少安全隐患，同时，将放电丝4与外框分离配置的方式，也可以降低更换过滤纸1的复杂度。
实施例二，参照图4-图6所示，本实施例所提供的过滤装置与上述实施例一所提供的过滤装置不同之处在于，所述放电丝4a为平行两条设置，两条放电丝4a之间的中心点位置与上述实施例一中放电丝4的位置对应，两条放电丝4a的设计进一步增加了电场形成后的均匀度以及强度。
以上所述仅为本实用新型的较佳实施例而已，并不用以限制本实用新型，凡在本实用新型的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本实用新型的保护范围之内。
