下面将结合附图对本发明的技术方案进行清楚、完整的描述，显然，以下所描述的实施例是本发明一部分实施例，并非全部实施例。
目前通过电离空气起到空气净化作用的装置主要包括负离子发生器和等离子发生器。其中，负离子发生器可以产生大量负离子与空气中的细菌、病毒、灰尘等带正电的微粒结合，使其凝聚沉降，从而达到减少空气中得细菌、病毒、灰尘等细小微粒的目的，但负离子并不能将细菌病毒真正杀死，且没有除异味的能力。而等离子发生器通过可以产生大量电子、羟基自由基等高能粒子，不仅可以对经过等离子体区的细菌、病毒起到良好的杀灭作用，还能够对空气中得异味起到良好的分解净化的作用，但高能粒子活性高、寿命短，只存在于电极附近微小的等离子体区域内，无法主动扩散到空气中形成主动杀菌效果，作用范围有限。可理解到，利用负离子和等离子对空气进行净化，两者具有不同的优势，也存在不足。
本发明实施例提供的空气净化装置1000适用于空调器，具有负离子发生器和等离子发生器的功能，兼顾了负离子和等离子的优点，不仅可以将负离子主动扩散到空气中起到除菌的效果，也可以对经过空气净化装置1000的空气起到细菌病毒起到杀灭作用，同时具有一定的除异味效果，从而能够对室内空气进行净化处理，提高室内空气质量。
参照图1所示，本发明实施例的空气净化装置1000，包括壳体100和离子发生组件200，壳体100包括防护罩110和底座120，防护罩110与底座120连接，以在防护罩110与底座120之间形成腔体，离子发生组件200安装在腔体内。离子发生组件200包括第一电极210、第二电极220和第三电极230，其中第一电极210为负离子电极240，用于高压放电产生负离子；第二电极220和第三电极230间隔设置，第二电极220和第三电极230分别连接的电源电极，使两者之间存在电压差以形成强电场，从而能够产生等离子，实现 同时产生负离子和等离子，并利用负离子和等离子对空气进行净化。
参照图1所示，可以理解的是，防护罩110具有镂空结构，镂空结构可以是格栅、筛网或者其他镂空的结构，镂空结构形成有多个通孔，通过镂空结构罩设于离子发生组件200，产生的负离子能够经过通孔向外扩散，能够减少空气中得细菌、病毒、灰尘等细小微粒；同时空气也可以通过格栅结构进入到腔体内，利用等离子杀灭空气中的细菌、病毒，并具有除异味效果，使空气净化装置1000能够兼顾负离子净化和等离子净化的优点，净化效果更佳。需要说明的是，空气净化装置1000可安装在空调室内机(附图未示出)的出风口处，空调室内机工作时，出风口的气流有利于加快负离子的扩散，且利用等离子对流经的空气进行杀菌和除异味处理，能够有效净化室内空气，提高空调器的使用体验。在本发明的另一些实施例中，空气净化装置1000也可安装在空调室内机的进风口处或风道内。
参照图1所示，可以理解的是，第一电极210和第二电极220连接例如固定连接或可拆卸地连接在底座120上，第三电极230位于第二电极220的上方且连接例如固定连接或可拆卸地连接在防护罩110的内侧，使第二电极220与第三电极230隔开。第一电极210和第二电极220电性连接在一起，并通过第一导电件201例如导电线或其它导电件连接到电源(附图未示出)的高压极，该高压极为负高电压，负高电压的范围可以是-2kV至-15kV；第三电极230通过第二导电件202例如导地线或其它导电件连接到电源的接地极，其中，第一电极210为高压的负离子电极240，第二电极220为等离子高压电极250，第三电极230为等离子接地电极260，其中，负离子电极240形成单极尖端电晕放电以达到产生负离子的目的；等离子高压电极250与等离子接地电极260之间形成电压差，从而产生等离子体。可理解到，防护罩110和底座120采用绝缘材料制作，例如塑料、陶瓷等，且通过防护罩110的阻隔，使人手无法接触内部的多个电极，也可以对多个电极形成物理和电气保护，具有较高的防护性能，安全性更高。
参照图1所示，可以理解的是，第一电极210和第二电极220可以延伸到底座120内，例如底座120可以设有开口朝向防护罩110与底座120之间形成的腔体的凹槽，第一电极210和第二电极220放置到凹槽内，便于第一电极210和第二电极220的定位和组装，并且能减少尺寸。第一导电件201在底座120内例如凹槽内连接第一电极210和/或第二电极220并从底座120伸出以连接电源的高压极，第二导电件202在防护罩110内连接第三电极230并延伸向底座120，第二导电件202伸入底座120并从底座120伸出以连接电源的接地极。第一导电件201和第二导电件202可以从底座的同一出线孔伸出。采用上述布线方式能够保护第一导电件201和第二导电件202，避免布线杂乱，减少导线占用空间。
参照图1所示，可以理解的是，防护罩110内形成两个功能区，包括位于腔体内的第一功能区和第二功能区，第一功能区为第一电极210的负离子发生区101，第一电极210的数量不限于一个，实施例中设置有两个第一电极210，即包括两个负离子电极240，两个负离子电极240组成负离子发生区101。在另一些实施例中，第一电极210的数量可以为一个或三个以上。第二功能区为第二电极220与第三电极230之间形成的等离子发生区102，离子发生区位于等离子发生区102的两侧，在第一电极210和第二电极220通电后，在离子发生区产生负离子，在等离子发生区102产生等离子体。为了降低离子发生区与等离子发生区102产生相互干涉而影响净化效果，对第一电极210、第二电极220、第三电极230与防护罩110的组合结构进行优化，有利于实现空气净化装置1000的小型化设计，具体在以下实施例中能够体现出来。
参照图2和图3所示，图中示出第一电极210与第二电极220的连接结构，第二电极220包括电极板221，两个负离子电极240分别连接在电极板221的两端，实施例中，首先负离子电极240与电极板221采用焊接等方式固定在一起，也可以利用导线连接在一起，具体不作限定；然后将负离子电极240与电极板221固定在底座120上，并通过导电线将负离子电极240与电极板221连接到同一电源的高压极，这样由同一路导电线提供相同的高压电，同时给负离子电极240和等离子高压电极250进行供电，无需配置两套电源，降低了离子发生组件200对高压电源的要求，有利于降低成本。
参照图2和图3所示，可以理解的是，负离子电极240的端部设有第一尖端部211，电极板221设有第二尖端部222，第二尖端部222朝向第三电极230设置。本发明实施例中第一尖端部211采用碳纤维材料制作，第一尖端部211包括多根碳纤维刷毛，负离子电极240的底部为基部212，利用基部212将碳纤维刷毛进行箍缩，使碳纤维刷毛根部固定于基部212并从基部212伸出形成尖端结构，第一尖端部211连接负高电压后形成单极尖端电晕放电，从而达到产生负离子的目的；碳纤维刷毛通过基部212焊接在电极板221并与电极板221电连接，加工、组装也更简便，无需布置走线，有利于减小空间的占用，实现小型化。在另一些实施例中，第一尖端部211还可以采用其他导电纤维，第一尖端部211也可以是锯齿、针尖等尖端结构，例如第一尖端部211可以是金属针结构，具体不作限定。
参照图1和图3所示，需要说明的是，将负离子电极240设置在等离子高压电极250的两侧，两个第一尖端部211分别位于第二尖端部222的两侧，且两个第一尖端部211与第二尖端部222隔开一定的距离，能够减小第一尖端部211高压放电对等离子发生区102的电场的干扰，能够使局部电场更加均匀，同时也有利于负离子的分布和扩散。在一些实 施例中，负离子电极240也可以设置有三个或以上，此外负离子电极240不限于设置位于电极板221的两侧，也可以将负离子电极240设置在电极板221的同一侧，使负离子发生区101位于等离子发生区102的一侧。
参照图2和图3所示，本发明实施例中，电极板221为金属板，第三电极230为金属条，电极板221设有多个齿状的第二尖端部222，多个第二尖端部222沿电极板221的长度方向排列，形成锯齿结构，电极板221通过锯齿结构进行放电，与金属条配合能够产生强电场，从而产生等离子体。需要说明的是，第二尖端部222与电极板221一体成型，电极板221与金属条均采用不锈钢材料制作而成，具有较佳的防腐蚀能力，提高电极结构的耐用性；电极板221与金属条也可以采用其它具有防腐蚀能力的材料制作。第二尖端部222也可以是针尖、细丝等曲率半径较大的形状，具有较强的放电性能，具体不作限定。
参照图1、图4和图6所示，防护罩110包括边框112和连接于边框112的多个格栅条111，多个格栅条111沿底座120的长度方向间隔排列形成格栅从而构造出镂空结构，边框112大致呈长方形，每个格栅条111折弯大致呈U形状且格栅条111的两端分别与边框112连接，格栅条111与边框112一体成型，结构稳定可靠；相邻格栅条111之间形成间隙，负离子发生区101和等离子发生区102均与间隙连通；负离子电极240产生的负离子能够通过间隙向外扩散，空气也可以通过间隙进入到等离子发生区102。需要说明的是，不同位置的间隙的尺寸可设置各不相同，也可以是设置所有间隙的尺寸一致，如图4所示，该间隙为L1，满足L1≤6mm(毫米)，也就是说，相邻格栅条111的间距小于等于6mm，且间隙不为零，例如间隙可设置为3mm、5mm等，确保人手指无法触碰到内部的电极。
参照图4所示，需要说明的是，边框112设有第一卡扣121，底座120设有与第一卡扣121对应的卡槽，通过第一卡扣121扣接于卡槽中，使防护罩110与底座120实现连接，也便于装配。在另一些实施例中，也可以在底座设置卡扣，在边框设置卡槽，通过卡扣与卡槽的配合实现装配。防护罩110与底座120完成装配后，沿底座120的宽度方向，两个第一尖端部211均露出于间隙处，即格栅条111不会遮挡第一尖端部211，有利于加快负离子的扩散，提高净化效率；可理解到，空气净化装置1000安装到空调后，防护罩110的长度方向与空气流动方向垂直或相互成夹角，使气流能够从防护罩110沿宽度方向的侧面的间隙进入，并直接吹向第一尖端部211。在间隙满足上述条件的情况下，可适当增加靠近第一电极210位置的间隙的间距，或者将与第一尖端部211对应的间隙的间距设置相对其他位置的间隙间距更大，进一步提高负离子的扩散效率。
参照图4所示，需要说明的是，第一尖端部211的高度大于基部212的高度，第一尖 端部211与基部212的高度之和大于边框112的高度，使第一尖端部211不会被边框112完全遮挡，即确保第一尖端的至少部分高出于边框112并能够露出于间隙，不影响负离子的扩散。实施例中，基部212的高度设置大于边框112的高度，这样能够使第一尖端部211完全露出于间隙。
参照图1、图4和图5所示，防护罩110还设有连接格栅条111的多条连接筋113，连接筋113沿防护罩110的长度方向设置，通过连接筋113能够提高格栅结构的稳定性，使防护罩110整体更加牢固可靠。其中，金属条固定在防护罩110的顶壁的至少一个连接筋113，金属条位于连接筋113的底面，通过连接筋113对金属条形成覆盖，使金属条得到防护，人手或其他异物从防护罩110的外侧无法触摸金属条，确保电气安全；可以理解的是，将等离子接地电极260固定在防护罩110，省去防护罩110与等离子高压电极250之间的空间，有利于实现整体结构小型化设计，降低了空气净化装置1000对安装空间的要求。
参照图1和图4所示，需要说明的是，等离子高压电极250固定在底座120，等离子接地电极260固定在防护罩110，通过调整防护罩110高度，可以调整金属条与锯齿结构之间的距离，以此来达到调节等离子强度和电气安全的目的，此外也可以通过调节供电电压，改变产生的等离子体的强度；具体根据实际应用场景来调整两电极之间的距离与所供高压电的匹配关系，以达到较佳的净化效果。
参照图5所示，图5示出空气净化装置1000的俯视图，需要说明的是，沿防护罩110的高度方向，金属板与金属条是错位的、不对齐的，也即是金属条并非位于金属板的正上方，金属板与金属条之间形成的电场方向具有倾斜角度，在保证金属板与金属条之间所需距离的基础上进一步减少空气净化装置1000的尺寸；而且实施例中金属条的长度大于金属板的放电部分例如锯齿结构的长度，可以在保证两电极之间具有足够安全距离的前提下，能够形成扇形的等离子发生区102，有利于增大等离子发生区102的空间范围，提升净化效果。
参照图5所示，可以理解的是，实施例中，金属条沿底座120的长度方向的延伸长度小于等于连接筋113的长度，且金属条的宽度小于等于连接筋113的宽度，也即是连接筋113能够完全覆盖金属条，人手指从防护罩110外侧无法触碰金属条。需要说明的是，金属条的两端分别设有连接耳(附图未示出)，在两个格栅条111分别设置与连接耳匹配的遮挡部114，两个连接耳分别固定连接在两个遮挡部114的底面，通过遮挡部114能够遮挡连接耳，进一步提高电气安全性。此外，金属条通过导电线连接电源的接地极，导电线 由防护罩110的顶壁延伸到底座120并从底座120引出，便于与电源连接。
参照图4所示，实施例中，第一尖端部211与金属条之间的距离为L2，该距离L2为第一尖端部211与金属条沿长度方向的间距，第二尖端部222与金属条之间的距离为L3，满足：L2＞L3，即第一尖端部211与金属条的间距需要大于第二尖端部222与金属条的间距，能够减小负离子发生区101对等离子发生区102的干扰。可以理解的是，由于第一尖端部211和第二尖端部222均为高压电极，若第一尖端部211与金属条的距离更近，会对第二尖端部222与金属条之间形成的电场产生干扰，影响等离子发生区102的形成，从而影响等离子体的产生。在满足所述条件L2＞L3的情况下，第一尖端部211与金属条隔开足够大的距离，能够达到电极放电的作用，并产生负离子，第二尖端部222与金属条配合能够产生稳定的电场，从而确保等离子发生区102的稳定性。
参照图4和图5所示，考虑到负离子电极240和等离子高压电极250工作时连接高压电极，实施例中负离子电极240与防护罩110的间距设置大于等于3mm，同时等离子高压电极250与防护罩110的间距也设置大于等于3mm，可理解到，负离子电极240和等离子高压电极250均连接在底座120上，因此，负离子电极240与防护罩110在各个方向的间隔均需满足不少于3mm，等离子高压电极250与防护罩110在各个方向的间隔均需满足不少于3mm，例如，负离子电极240与防护罩110之间隔开3mm、4mm、6mm等。
参照图6所示，图6示出空气净化装置1000的侧面示意图，底座120还设有用于第二卡扣122，通过第二卡扣122与空调室内机连接，使空气净化装置1000能够装配到空调室内机，装配简便快捷；或者，可以在边框112设置卡扣用来与空调室内机连接；空气净化装置1000与空调室内机的安装方式不限于扣接，也可以采用螺栓连接等方式进行装配，具体不作限定。
本发明实施例还提供一种空调器(附图未示出)，包括上述实施例的空气净化装置1000，以空调器的空调室内机示例，空气净化装置1000可以安装在空调室内机的出风口处，兼顾了负离子和等离子的优点，出风口的气流有利于加快负离子的扩散，不仅可以将负离子主动扩散到空气中起到除菌的效果，也可以对经过空气净化装置1000的空气起到细菌病毒起到杀灭作用，同时具有一定的除异味效果，从而能够对室内空气进行净化处理，提高室内空气质量。
上面结合附图对本发明实施例作了详细说明，但是本发明不限于上述实施例，在所属技术领域普通技术人员所具备的知识范围内，还可以在不脱离本发明宗旨的前提下作出各种变化。
