为了保持本实用新型实施例的以下说明清楚且简明，本实用新型 省略了已知功能和已知部件的详细说明。
本实用新型实施例提供了一种空气净化器。如图1至图5所示，该空气净化器包括机身以及设于机身内的过滤系统1和排风系统2。空气净化器还包括UV灯组件3(紫外线灯组件)，UV灯组件3设于过滤系统1和排风系统2之间并位于机身内的空气的流动路径上，UV灯组件3发出的光的照射方向倾斜或垂直于空气的流动方向，以便能够在空气的流动路径的截面上形成密集的光屏障35。该截面为垂直或大致垂直于流动路径的横截面。也就是，UV灯组件3发出的光能够以垂直或稍倾斜于空气的流动方向照射，但能够形成垂直或大致垂直于空气的流动方向的光屏障35。
本实用新型实施例的一种空气净化器，在空气的流动路径上设置UV灯组件3，UV灯组件3发出的光可以在垂直于空气的流动方向形成光屏障35，实现对由过滤系统1进入排风系统2的空气进行全面覆盖杀菌，杀菌效果可靠性强。
在一些实施例中，如图7至图9所示，UV灯组件3包括固定支架31和多个UV灯32。固定支架31内形成用于使空气由过滤系统1进入排风系统2的通路314。该通路314形成空气流动过程中通过的流动路径的一部分。多个UV灯32围绕固定支架31的周向布设于固定支架31上，以使UV灯32形成的密集光屏障35尽可能布满固定支架31内的通路314，当空气流经该通路314时被全面消杀净化，提高空气质量。
在一些实施例中，继续结合图7至图9，固定支架31的周向上设有与通路314分别连通的多个容腔315，多个UV灯32一一对应的装设于多个容腔315内；容腔315的腔壁上设有卡扣316，卡扣316将UV灯32扣紧在容腔315内。该结构简单，固定方式稳定可靠。
UV灯32的数量不做具体限定，可以为两个以上的任意多个，只要能够满足横向环绕照射，形成光屏障35，对空气实现良好杀菌即可。多个UV灯32可以在固定支架31上均布，以使光屏障35各处的密度大致相同，杀菌效果一致。
在一些实施例中，继续结合图7至图9，固定支架31可以为环形，环形的轴向方向与空气的流动方向一致。UV灯32包括灯板321和装设于灯板321上的灯体322。容腔315由固定支架31的外壁面311贯通 至固定支架31的内壁面312。容腔315靠近内壁面312的一侧的腔壁上设有挡台313，容腔315靠近外壁面311的一侧的腔壁上设有卡扣316，挡台313和卡扣316配合限定出定位槽。当UV灯32装设于容腔315时，灯板321的周侧卡入定位槽。上述结构设计合理，能够方便稳定的将灯板321固定于容腔315内。
在一些实施例中，如图8所示，挡台313对应容腔315的顶壁和底壁的部分的中部分别形成缺口，如此，可以避免挡台313对UV灯32发出的光造成阻挡，即使将挡台313做高也不会干涉光的发射。卡扣316包括两个，两个卡扣316分别相对应的设于容腔315的顶壁和底壁上。通过两个对应设置的卡扣316的配合，可以将灯板321稳定的限定于容腔315内。
如图7至图9所示，容腔315的顶壁由外壁面311向内壁面312开设有两个并行的条形槽318，以使容腔315靠近外壁面311的部分顶壁形成弹臂317。其中一个卡扣316设于弹臂317上。如此，便于设于弹臂317上的卡扣316随弹臂317发生形变，利于UV灯32卡入卡扣316内。
在一些实施例中，如图7和图9所示，灯板321以板面平行于空气的流动方向的方式装设于容腔315内。灯体322垂直装设于灯板321朝向通路314的一侧板面上。如此，利于灯体322发出的光能够朝向垂直于空气的流动方向照射，形成横向环绕照射，提高对空气的杀菌净化效率。
在一些实施例中，如图7至图9所示，固定支架31的内壁面312对应容腔315的位置设有遮光筋33，遮光筋33至少从上方遮挡UV灯32。如此，可以避免UV灯32发出的光向上散射，提高光的利用率，增加光屏障35的密度，进而提高杀菌的效果和效率。
进一步的，继续结合图7至图9，遮光筋33的截面呈倒置的U形，并罩在容腔315朝向流动路径的一侧。如此，可以更好的聚拢灯光，将灯光聚拢在固定支架31围成的通路314内，在通路314内形成密集的光屏障35。
可以理解的是，UV灯组件3可以设于过滤系统1和排风系统2之间的空气流动路径的任何位置，只要能够对经由过滤系统1过滤后的 空气在进入排风系统2排出之前进行紫外线杀菌即可。UV灯组件3的固定支架31的外轮廓应该与空气的流动路径的某一横截面的周缘贴合，以使空气经过UV灯32杀菌后才能进入排风系统2进行对外排放。
在一些实施例中，如图2、图3和图5所示，排风系统2包括外壳23、风道组件21和电机22。风道组件21和电机22均设于外壳23内。风道组件21包括用于引导空气流动的风轮211，电机22与风轮211连接，用于驱动风轮211转动。风道组件21的下端形成进风口212，风道组件21的上端形成出风口24。过滤系统1包括机身座12、滤网盖14和滤网组件11。机身座12内形成用于容置滤网组件11的容腔315，机身座12的周侧设有用于将滤网组件11装入容腔315内的安装口13。滤网盖14用于封盖安装口13，以将滤网组件11封盖在机身座12的容腔315内。机身座12和滤网盖14上布满进气孔。空气净化器在工作时，电机22带动风轮211转动，空气在转动的风轮211的作用下通过进气孔进入滤网组件11，经滤网组件11过滤后进入进风口212，最后由风道组件21的出风口24排出，形成空气的循环流动和净化，同时，空气在循环流动时，在进风口212处进入UV灯32照射区域产生的光屏障35后进行杀菌，提升空气净化器的净化功能。当然，过滤系统1的结构不限于上面描述的情况，而是可以根据实际需要做变形或改变。图3中箭头方向，表示空气的流动方向。
如图2至图5所示，UV灯组件3可以设于排风系统2的进风口212处。如图6所示，进风口212的内壁面312上设有卡槽213。固定支架31的外壁面311上设有卡凸34。固定支架31为与进风口212的形状适配的圆环形，固定支架31设于进风口212内，固定支架31的外壁面311与进风口212的内壁面312贴合，且卡凸34嵌入卡槽213内，以使固定支架31稳定的固定于进风口212内。将固定支架31设计为环形并与环形的进风口212环形贴合，以减小对进风口212的进风面积的占用，避免影响空气净化器的工作效率。卡槽213和卡凸34的数量根据实际需要确定，只要能够保证固定支架31与进风口212结合的稳定即可。例如，本实施例中示出了两个卡槽213和两个卡凸34，两个卡槽213在进风口212的内壁面312均布。
多个UV灯32可以围绕环形的固定支架31均布，即相当于均匀的 设置在进风口212上，呈现环形横向照射，使进风口212无死角产生光屏障35。图中示出的光屏障35仅以多条点划线示意性的表示，实际光线是密集的，布满整个进风口212。
如图8和图9所示，每个UV灯32的灯板321上分别设有接线端子36，多个灯体322的接线端子36可以连接到同一根供电线缆37上，供电线缆37在与供电电源连接，实现同时为多个UV灯32供电。
本实用新型实施例的空气净化器，UV灯组件3在风道组件21的进风口212处产生光屏障35，使空气循环通过光屏障35进行杀菌，结构简单合理，可靠性强，可普遍应用在空净消杀类产品上。
以上描述旨在是说明性的而不是限制性的，本领域的普通技术人员在本公开的范围内可以对上述实施例进行变化、修改、替换和变型。而且上述示例(或其一个或更多方案)可以彼此组合使用，并且考虑这些实施例可以以各种组合或排列彼此组合。
