具体实施方式
以下结合附图对本发明作进一步的详细说明。
本具体实施例仅仅是对本发明的解释，其并不是对本发明的限制，本领域技术人员在阅读完本说明书后，可以根据需要对本实施例做出没有创造性贡献的修改，但只要在本发明的权利要求范围内都受到专利法的保护。
实施例：如图1至图4所示，一种空气净化器的滤网结构，包括边框1和安装在边框1内的过滤网2，边框1固定安装在净化器的进风口处。
过滤网2的外侧设置有导风板3，导风板3间隔分布在边框1内，且导风板3的两端通过转轴5安装在边框1上，边框1上设置有驱动导风板3摆动的调节机构4。
如图2所示，调节机构4包括连杆401、滑块402、传动杆403和偏心转动件404，沿同一方向间隔分布的多个导风板3连接在同一连杆401上，滑块402固定在连杆401的端部并可移动地安装在边框1上，所述偏心转动件404由电机驱动转动，传动杆403连接在滑块402与偏心转动件404之间。
连杆401上设置有长槽405，导风板3上设置有伸入长槽405内的连接轴6，连接轴6可在长槽405内自由移动。
连杆401和连接轴6设置在导风板3的端部，连接轴6与转轴5平行设置。
如图3和图4所示，导风板3包括横向导风板3a和竖向导风板3b，横向导风板3a沿上下方向间隔分布在边框1内，竖向导风板3b沿左右方向间隔分布在边框1内。竖向导风板3b设置在过滤网2的外侧，横向导风板3a设置在竖向导风板3b的外侧。气流从进风口进入净化器内部时，先被横向导风板3a分隔成上下流动的横向气流，然后被每股横向气流被竖向 导风板3b分隔成左右流动的竖向气流，从而将通过过滤网2的气流分隔成小股气流，
竖向导风板3b的靠近过滤网2的一侧设置由清洁毛刷。
导风板3的横截面为梭形，导风板3的表面设置有导风条，导风条沿导风板3的宽度方向延伸，并沿导风板3的长度方向间隔分布，相邻两条导风条之间形成导风槽。
导风板3为分体式结构，包括板本体301和活动板体302，板本体301通过转轴5安装在边框1上，活动板体302设置在板本体301的一侧并铰接在板本体301上，所述板本体301与活动板体302之间设置有使活动板体302靠向板本体301的弹性复位件。活动板体302的外侧面为圆弧面，所述导风条设置在活动板体302的圆弧面上。当气流速度过大时，活动板体302外侧的气压变小，使得活动板体302向外张开，使得活动板体302与相邻导风板3的间隙变小，从而自动调节进入净化器内部的气流流量。
