请一并参阅图1及图2，本发明实施方式的油烟净化模块100包括集尘壳体10和静电发射元件30。集尘壳体10形成有风道11。静电发射元件30设置在风道11内。
静电发射元件30包括安装部32和多个发射极针34。安装部32包括第一安装面321，第一安装面321与集尘壳体10的内表面13相对设置。多个发射极针34设置在第一安装面321法向上且朝向内表面13，多个发射极针34沿安装部32的周向阵列分布。
上述油烟净化模块100中，可在静电发射元件30与集尘壳体10之间形成 静电场以使流经风道11的油烟颗粒带电，使得油烟颗粒运动附着在集尘壳体10上，从而实现油烟净化的效果，使得油烟的清洁度提高。
需要指出的是，集尘壳体10、静电发射元件30及发射极针34均具有导电性，在一个例子中，集尘壳体10、静电发射元件30及发射极针34均可以由金属材料制成，例如不锈钢、铝合金等。
集尘壳体10上可以接上正高压电极，静电发射元件30上可以接上负高压电极，由此，在集尘壳体10与静电发射元件30之间可以形成静电场。
由于发射极针34设置在静电发射元件30上，因此，发射极针34具有负高压，发射极针34通过高压放电或者尖端放电，可以将风道11中的空气电离形成负离子，在静电场的作用下，负离子可以获取能量，并由发射极针34附近向集尘壳体10运动，当油烟颗粒经过风道11时，油烟颗粒与负离子结合从而带上负电，并向集尘壳体10运动，最后吸附在集尘壳体10上。因此，油烟净化模块100可以减少排出油烟净化的油烟，从而实现油烟净化的效果。
需要指出的是，在一个例子中，高压的电压为8000-40000V。例如为9000V、10000V、15000V、20000V、30000V、35000V等电压值。
在某些实施方式中，集尘壳体10包括多个子壳体15，子壳体15形成有风道11，多个子壳体15同轴间隔设置，相邻的两个子壳体15之间和位于最内侧的子壳体15内均设置有静电发射元件30。
如此，多个子壳体15有利于增大集尘壳体10的集尘面积，从而可以提高油烟净化模块100的烟油净化能力。静电发射元件30设置在不同的位置，就可以使得静电场分布均匀，进一步有利于油烟净化。
每个子壳体15例如呈圆筒状，这样可以减小油烟流动的阻力，以降低油烟流动所产生的噪音。当然，每个子壳体15也可以呈方筒状。
在某些实施方式中，位于相邻的两个子壳体15之间的静电发射元件30中，安装部32呈筒状，安装部32包括与第一安装面321相背的第二安装面322， 第二安装面322与位于内侧的子壳体15的外侧面相对，第二安装面322设置有多个发射极针34。
如此，安装部32的形状可以与子壳体15的形状配合，使得油烟净化模块100更加紧凑。在安装部32相背的两个表面均设置发射极针34，使得与安装部32相邻的两个子壳体15均能吸附油烟颗粒，从而可以提高油烟净化模块100净化油烟的能力。
在某些实施方式中，位于最内侧的子壳体15内的静电发射元件30中，第一安装面321沿子壳体15的轴向呈梭形或翼形。
如此，油烟颗粒经过最内侧的子壳体15内的静电发射元件30时，阻力较小，从而可以提高油烟净化模块100的排烟能力。
在某些实施方式中，子壳体15的数量为两个，静电发射元件30的数量为两个，其中一个静电发射元件30位于两个子壳体15之间，另一个静电发射元件30位于最内侧的子壳体15内。
如此，两个子壳体15既能满足油烟净化模块100净化油烟的能力，又可以使得油烟净化模块100的结构较为简单，容易制造，从而可以降低油烟净化模块100的成本。
在某些实施方式中，油烟净化模块100包括支撑架50，集尘壳体10与静电发射元件30均固定在支撑架50上。
如此，支撑架50可以将集尘壳体10与静电发射元件30固定一起，以使油烟净化模块100可以形成模块，有利于油烟净化模块100安装至相应的排烟装置中。
可以理解，支撑架50可以为塑料等绝缘材料制成，以防止集尘壳体10与静电发射元件30出现短路现象。
集尘壳体10与静电发射元件30可以通过卡接、焊接等方式固定在支撑架50上。
在某些实施方式中，风道11具有进风口111及与进风口111连通的出风口112，支撑架50设置于进风口111和/或出风口112处，支撑架50形成有与风道11连通的通风孔52。
如此，通风孔52可以保证油烟经过风道11，使得油烟颗粒可以吸附在集尘壳体10上。
具体地，支撑架50包括同心间隔设置的多个环形条54和固定连接多个环形条54的多个连接筋56，多个连接筋56绕环形条54的圆周方向间隔分布，相邻的两个环形条54与相邻的两个连接筋56共同限定通风孔52。
在某些实施方式中，发射极针34上设置有多个刷毛。
刷毛的材料例如为碳纤维等导电材料制成，如此，刷毛通过放电电离空气，以增大负离子的释放当量，从而可以增强负离子的发射效果以提高油烟净化模块100的净化效果。
在某些实施方式中，油烟净化模块100包括静电发生器70，静电发生器70的一个连接端连接集尘壳体10，另一个连接端连接静电发射元件30。
例如，静电发生器70的正极连接端连接集尘壳体10，负极连接端连接静电发射元件30。静电发生器70可以接入220V的工作电压，静电发生器70可以将220V的电压通过电路提升至高电压，并通过连接端连接集尘壳体10和静电发射元件30。
具体地，静电发生器70可以将交流电通过降压电路、整流滤波电路、稳压电路等形成稳定的直流电源，直流电源为电路提供能量，经自激振荡电路、多级倍压整流电路，从而可获得高压。
请参阅图3，本发明实施方式的排烟装置200包括以上任一实施方式的油烟净化模块100。
本发明实施方式的排烟装置200中，可在静电发射元件30与集尘壳体10之间形成静电场以使流经风道11的油烟颗粒带电，使得油烟颗粒运动附着在集 尘壳体10上，从而实现油烟净化的效果，使得油烟的清洁度提高。
具体地，排烟装置200开设有吸烟口202，吸烟口202与风道11连通。排烟装置200内可设置有风轮(图未示)。一般地，排烟装置200安装在灶台上方，用户在灶台上进行烹饪时，可开启排烟装置200，以使风轮转动。风轮在转动的过程中可以将灶台上的烹饪器具产生的油烟通过吸烟口202吸入排烟装置200内，之后将油烟排至油烟净化模块100。油烟净化模块100与室外连通，油烟在油烟净化模块100净化后排向室外。
风轮在工作转动时，一方面可以将油烟从吸烟口202吸入至油烟净化模块100，另一方面，还可以将油烟分割成更小的颗粒，有利于油烟在油烟净化模块100内吸附在集尘壳体10上。
为了提高排烟装置200的寿命，在吸烟口202处设置有滤网204。滤网204可以将较大的油烟颗粒过滤，以防止较大的油烟颗粒直接进入排烟装置200内而影响排烟装置200正常工作。
在某些实施方式中，排烟装置200形成有油烟通道206，风道11与油烟通道206连通。
如此，油烟通道206可以将油烟排向风道11，以使油烟可以净化。油烟通道206与吸烟口202连通，风轮可以安装在油烟通道206内，从而使风轮工作时可以从吸烟口202吸入油烟，油烟经过油烟通道206后进入风道11。
在某些实施方式中，排烟装置200包括设置在油烟通道206中的整流模块210，相较于油烟净化模块100，整流模块210位于油烟气流的上游，整流模块210形成有沿油烟通道206的轴向呈波浪形延伸的多个整流通道212，整流通道212与风道11连通。
如此，多个整流通道212可以增大油烟通道206的阻力，从而将较大的油烟颗粒分离，并且可以将较大的油烟分颗粒解形成较小的油烟颗粒，以使进入风道11后的油烟颗粒更小，有利于油烟颗粒与负离子结合而带上负电，进而可 以吸附在集尘壳体10上。
请参阅图4，在某些实施方式中，整流模块210包括框体214和多个整流板216。多个整流板216沿油烟通道206的径向堆叠设置在框体214上，每个整流板216沿油烟通道206的轴向呈波浪形延伸，相邻的两个整流板216共同限定整流通道212。
框体214可以呈圆环状，从而使得整流模块210大致呈圆柱形，进而与油烟通道206更好的配合。整流板216可以通过焊接的方式焊接在框体214上，以形成整流模块210。
在本说明书的描述中，参考术语“一个实施方式”、“某些实施方式”、“示意性实施方式”、“示例”、“具体示例”、或“一些示例”等的描述意指结合所述实施方式或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施方式或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施方式或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施方式或示例中以合适的方式结合。
