请参阅图1和图2，本申请实施方式的油烟净化机300包括油烟机200和本申请实施方式中的净化器100，油烟机200包括风罩201和设置在风罩201内的风机202，风机202能够将油烟吸入至风罩201内，净化器100设置在油烟机200上方且与风罩201连通，以对吸入的油烟进行净化。
风罩201可以呈漏斗状结构罩设下方的灶台，以更好地吸附烹饪时产生的油烟。风罩201的上方可以形成有风道，风机202可以安装在风道内，风机202可以为轴流风机202或涡流风机202等。净化器100可以安装在风罩201的上方，且与风机202所在的风道相连通，风机202能够带动油烟流入至净化器100中进行净化。
本申请对于风罩201的具体结构、风机202的种类以及风机202和净化器100相对于风罩201的安装位置等不做具体限制，使得风机202能够将油烟吸入至净化器100进行净化排出即可，经净化器100净化后排出的气体能够更加干净清洁，有效地去除油烟中的有害物，提升用户的使用效果。
请参阅图2-图4，本申请实施方式的净化器100包括壳体10、固定座 20、紫外灯30、臭氧发生器40、上遮光板91和下遮光板92。壳体10内形成容置空间11，固定座20设置在容置空间11内，固定座20上形成有通光孔22，通光孔22与容置空间11连通。紫外灯30安装在固定座20内且能够通过通光孔22向容置空间11发射光线，臭氧发生器40设置在容置空间11内且位于固定座20下方。上遮光板91和下遮光板92均设置在容置空间11内，上遮光板91位于固定座20上方，下遮光板92位于固定座20下方。
本申请实施方式的净化器100中，气流可先经臭氧发生器40进行灭菌除臭处理后流入至固定座20处，在紫外灯30的照射下进一步灭菌及分解臭氧处理，使得流经净化器100后排出的气流更加干净清洁。紫外灯30安装在固定座20内通过通光孔22射出紫外光，同时固定座20的上下方均设置有遮光板，进而能够有效阻止紫外光外泄，避免造成紫外辐射，使得净化器100在使用时更加安全可靠，提升用户的使用体验。
具体地，壳体10可以设置为圆柱体或棱柱体等，壳体10可以与下方的风罩201相连。壳体10能够对内部的紫外灯30、臭氧发生器40等元件起到保护作用，也能够起到装饰作用以使净化器100的整体外观更加美观。壳体10的内部呈空心结构，内部空心即可以为容置空间11，风道管、紫外灯30等部件均可以安装在容置空间11内。
固定座20可以设置为中心位置形成有气流通道21的环形块状结构，气流通道21沿壳体10的长度方向延伸设置，固定座20横置于容置空间11的中部位置。固定座20上气流通道21的两侧设置有内部中空的安装腔23，紫外灯30可固定于安装腔23内。
如图3和图4所示，安装腔23与中心的气流通道21之间可以形成有通光孔22，紫外灯30发出的光线可由通光孔22射出。紫外灯30发出的紫外线能够由通光孔22射入至气流通道21中，以对气流通道21中流过的气流进行消毒灭菌。
同时，固定座20可以为屏蔽紫外线的材质制成。紫外灯30安装在安装腔23内并通过通光孔22发射紫外光进行除菌，能够有效防止紫外线外泄，避免紫外线辐射泄露至外部，影响用户使用时的安全性。
其中，紫外灯30的工作原理可以为：紫外灯30的灯管内的汞原子在电压下被激发产生汞的特征谱线，低压汞蒸气主要产生nm的紫外线。紫外灯30的灯管使用透紫外线玻璃或石英玻璃制成，紫外线能穿过玻璃壁投射出来。nm波长的紫外线很容易被生物体吸收，作用于生物体的遗传物质DNA，促使DNA遭到破坏而导致细菌死亡，可有效地杀灭细菌。紫外线可集中很高的强度在短时间内杀灭细菌和病毒，例如大肠杆菌和结核杆菌只需要0.4秒即可杀灭，所述紫外线杀菌属于纯物理消毒方法，无二次污染。
臭氧发生器40可以设置在容置空间11内且位于固定座20的下方，臭氧发生器40能够产生臭氧。臭氧是一种强氧化剂，能破坏分解细菌的细胞壁，从而扩散进细胞内部并氧化分解细菌氧化葡萄糖所必须的葡萄糖氧化酶等，也可以直接与细菌、病毒发生作用，从而破坏细菌的代谢和繁殖过程。另外，臭氧可以氧化各种有臭味的无机或有机物质，例如，臭氧可以分解氨气、苯、硫化氢等具有气味性的气体，从而起到除臭的作用。总之，臭氧灭菌、消毒和除臭的时间短，效果强，利用电离空气形成臭氧从而去除异味，可以取得较好的效果。
由风机202导进容置空间11内的气流将先流经臭氧发生器40进行去味灭菌处理，然后再进行紫外光杀菌处理，使得净化器100的杀菌效果更好。同时，由于紫外线还能够加速臭氧的消解速率，提升氧化能力，当气流经臭氧发生器40进行高压电离除味以后，带有臭氧的气体会继续向上流动，混合气体在紫外线的协同作用下，由于羟基自由基的形成，有效地破坏了有机物的分子结构并最终使得臭氧分解，分解臭氧后的气体再排出到室内或室外，以避免臭氧随气流排出而造成环境污染或影响用户健康。
如图4所示，上遮光板91和下遮光板92均设置在容置空间11内，其形状与对应安装位置处容置空间11的形状相适配。上遮光板91可以位于固定座20的上方，即紫外灯30的上方；下遮光板92可以位于固定座20的下方，即紫外灯30的下方，进而上遮光板91和下遮光板92能够更好地隔绝紫外灯30产生的辐射，防止紫外泄露。需要说明的是，上遮光板91和下遮光板92均设置为可通气结构，不会影响气流在容置空间11内的流 动。
另外，臭氧发生器40可以位于固定座20和下遮光板92之间，也可以位于下遮光板92的下方，本申请对此不做限制，不会影响臭氧发生器40对气流进行去味灭菌效果即可。
请参阅图3和图4，在某些实施方式中，上遮光板91和下遮光板92均为百叶结构。如此，百叶结构不仅能够有效地遮挡住紫外灯30发出的紫外光，防止紫外辐射外泄；也不会影响气流的流动，气流可以由百叶结构的间隙中顺畅地流动。
在某些实施方式中，上遮光板91可以设置为两个，两个上遮光板91并列设置。如此，两个上遮光板91能够更好地遮挡向上射出的紫外光，防止紫外辐射从上方外泄。
在某些实施方式中，下遮光板92可以设置为两个，两个下遮光板92并列设置。两个下遮光板92能够更好地遮挡向下射出的紫外光，防止紫外辐射从下方外泄。
具体地，两个上遮光板91均可以为百叶结构，沿气流的流动方向并列设置。如图5和图6所示，两个上遮光板91的百叶结构可以同向设置以使得流能够更好地流通，也可以交叉设置以具有更好地遮光效果。本申请对此不做具体限制。
相同地，两个下遮光板92均可以为百叶结构，沿气流的流动方向并列设置。两个下遮光板92的百叶结构可以同向设置以使得流能够更好地流通，也可以交叉设置以具有更好地遮光效果。本申请对此不做具体限制。
请参阅图3-图6，在某些实施方式中，固定座20包括第一部分24和第二部分25，第一部分24和第二部分25扣合连接。如此，紫外灯30能够更方便地安装至固定座20中的安装腔23内。
具体地，固定座20可以沿轴向分隔为第一部分24和第二部分25，第一部分24和第二部分25围成气流通道21。通光孔22可以设置在第一部分24和第二部分25的扣合间隙处，朝向气流通道21方向。
紫外灯30在安装时，可以先紫外灯30部分伸入至第一部分24的安装腔23内，然后将第二部分25与第一部分24扣合连接，以将紫外灯30的 剩余部分遮住，进而紫外灯30能够完全处于安装腔23内，仅通过通光孔22向外发射光线，使得紫外光对气流通道21的气流灭菌效果更好，也能够防止紫外光外泄，同时还能够使得紫外灯30安装的更加稳定且安装拆卸更加方便。
请参阅图3-图6，在某些实施方式中，净化器100包括导风圈50，导风圈50设置在容置空间11内且位于固定座20和下遮光板92之间，臭氧发生器40设置在导风圈50内。
如此，导风圈50能够起到分流的作用，臭氧发生装置设置在导风圈50中能够更好地对流入的空气进行电离，灭菌去味效果更好。
具体地，导风圈50可以设置在下遮光板92的上侧，也可以设置在下遮光板92的下侧。臭氧发生器40设置在导风圈50内的中心位置。本申请对于导风圈50和臭氧发生器40的具体位置不做限制。导风圈50可以呈环形结构，导风圈50的顶部设置有分流板，分流板能够适当阻挡由下方风机202导入的气流，减缓气流的流速，使得臭氧发生器40更好地对流经的气流进行电离，以达到更好的去味灭菌效果。
请参阅图3-图6，在某些实施方式中，壳体10的顶部周侧开设有格栅孔12，上遮光板91位于格栅孔12的下方。
如此，净化后的气流可以通过格栅孔12排出至净化器100外部，上遮光板91位于格栅孔12下方以避免紫外辐射从格栅孔12处外泄。
具体地，格栅孔12可以形成在壳体10的顶部周侧，沿壳体10的周壁间隔设置。格栅孔12连通容置空间11和外界，经过臭氧除味、紫外线灭菌以及紫外线分解臭氧后的洁净气体便可以由格栅孔12排出至净化器100，排出的气体更加干净清洁且分解臭氧后的气体不会对人体有害。
其中，上遮光板91位于容置空间11内且设置在格栅孔12的下方，进而上遮光板91能够遮挡向上出射的紫外光，避免紫外光从格栅孔12射出而对外界产生紫外辐射。
请参阅图3-图6，在某些实施方式中，净化器100包括电控组件80，电控组件80安装在壳体10的顶板13上。
如此，净化器100可通过电控组件80对内部的紫外灯30以及臭氧发 生器40等元件进行控制。
具体地，顶板13可以为壳体10顶部的壁面，顶板13能够封住壳体10以使气流可以更好地由格栅孔12流出。电控组件80可以包括插座以及电路板等，插座能够连接外部地电源以起到供电的作用，电路板与内部各个元件电连接以对各个元件进行控制。
请参阅图3-图6，在某些实施方式中，净化器100包括风速传感器70，顶板13的内部设置有导流罩60，风速传感器70设置在导流罩60内。
如此，净化器100可通过风速传感器70对气流通道21内气流的流速进行感应，进而电控组件80可根据气流的流速来改变臭氧发生器40的电压强度，使得电离效果更好，灭菌祛味处理更加彻底。
具体地，导流罩60可以呈圆台或圆锥形倒挂设置在顶板13上，进而导流罩60能够对气流通道21流出的气流起到一定的引导作用，使得气流更好地流向壳体10侧壁上的格栅孔12。当然，导流罩60也可以呈棱柱、圆柱形或其他形状，本申请对于导流罩60的形状不做限制。
导流罩60的内部中空，风速传感器70以及电路板等可以安装在导流罩60内部。导流罩60朝向气流通道21的一侧可以形成有进气孔61，导流罩60的侧边可以形成有出气孔62，气流通道21中的气流能够由进气孔61流入并由出气孔62流出。
风速传感器70能够感应出流经气流的流速，进而使得电控组件80可以根据气流的流速来控制臭氧发生器40的工作电压。当气流流速较大时，则控制臭氧发生器40的工作电压升高，进而使得电离效果更好；当流速较小时，则控制臭氧发生器40的工作电压降低，避免产生过多的臭氧。
