这样设置使负离子发生装置产生的负离子从风道直接吹出，增大了负离子的迁移距离，且仅有发射头伸入气流通道，安设隐蔽，对出风气流影响小，靠近出风口，使得最终吹出负离子量更大，出风气流更顺畅、噪音更低，此外，通过导流部第一限位结构上的定位槽对发射头进行定位和安装，使发射头准确安设于风道内壁上，并可通过负离子发生装置上非发射头部分限位，防止发射头脱出定位槽，保证了发射头安装的稳定，同时使用导流罩压覆与风道内壁上，将发射头固定在安设位置，在不同方向上对发射头进行限位，提高了负离子发生装置在风道内壁上安装的稳定性，克服相关技术中负离子发生装置设于出风口稳定性差的缺陷，且结构简单，利于安装。
2.本公开提供的负离子发生器呈T型，与所述风道内壁卡接，包括横向柱和纵向柱，所述发射头突出设置于所述横向柱上靠近所述风道的一侧。
这样设置一方面便于在发射头在安装于定位槽后，通过横向柱进行限位， 保证了发射头不会脱出定位槽，提升了固定效果，T型设置的负离子发生器，便于操作人员在安设时确认正确的安装方向，且固定较少的部分即可达到限位目的，如固定横向柱的两侧即可达到限制多个方向自由度的效果，减少限位结构的设置，降低成本。
3.本公开提供的第一限位结构包括至少一个第二凸出部，背向所述风道内壁凸出设置，所述第二凸出部上设置有朝上延伸并与所述风道内壁间隔设置的弯折，所述纵向柱适于限位所述弯折与所述风道内壁之间的区域。

此外，下面所描述的本公开不同实施方式中所涉及的技术特征只要彼此之间未构成冲突就可以相互结合。
如图1-图8，本实施例中提供一种净化装置，包括：设有风道的导流部2；负离子发生装置4，负离子发生装置4包括发射头431，发射头431朝向风道， 导流部2上设有第一限位结构，第一限位结构设置于风道内壁21上，第一限位结构上设置有适于容纳发射头431的定位槽22；导流罩1，设置在风道内壁21上方并压覆定位槽22，风道内壁21适于支撑导流罩1。
这样设置使负离子发生装置4产生的负离子从风道直接吹出，增大了负离子的迁移距离，且仅有发射头431伸入气流通道，安设隐蔽，对出风气流影响小，靠近出风口，使得最终吹出负离子量更大，出风气流更顺畅、噪音更低，此外，通过导流部2第一限位结构上的定位槽22对发射头431进行定位和安装，使发射头431准确安设于风道内壁21上，并可通过负离子发生装置4上非发射头431部分限位，防止发射头431脱出定位槽22，保证了发射头431安装的稳定，同时使用导流罩1压覆与风道内壁21上，将发射头431固定在安设位置，在不同方向上对发射头431进行限位，提高了负离子发生装置4在风道内壁21上安装的稳定性，克服相关技术中负离子发生装置4设于出风口稳定性差的缺陷，且结构简单，利于安装。
在本实施例中，风道为环形设置，设于导流部2外缘位置，定位槽22为双槽，适于安装圆柱形发射头431，导流罩1下端与风道内壁21贴合，导流罩1与导流部2通过可拆卸的螺钉柱31连接，净化装置为空气净化器。
负离子发生装置4包括：负离子高压模块41、负离子发生器43和连接线42，导流部2中部设有电机固定架3，负离子高压模块41与电机固定架3上的螺钉柱31固定连接，连接线42连接负离子高压模块41和负离子发生器43，并通过设于电机固定架3上的卡线扣32固定在电机固定架3上。在本实施例中，卡线扣32得电机固定架3一侧固定有电机，负离子发生装置4固定在电机固定架3另一侧，电机固定架3可拆卸，负离子高压模块41通过两个螺钉柱31固定于电机固定架3上，连接线42为两根，卡接在设于电机固定架3中部的卡线扣32上，设在负离子发生器43设于风道内壁21靠近导流罩1的一侧。
作为可变换的实施方式，卡线扣32可以不设置，负离子高压模块41可以固定杂风道内壁21上。
负离子发生器43呈T型，与风道内壁21卡接，包括横向柱432和纵向柱433，发射头431突出设置于横向柱432上靠近风道的一侧。
这样设置一方面便于在发射头431在安装于定位槽22后，通过横向柱432进行限位，保证了发射头431不会脱出定位槽22，提升了固定效果，T型设置的负离子发生器43，便于操作人员在安设时确认正确的安装方向，且固定较少的部分即可达到限位目的，如固定横向柱432的两侧即可达到限制多个方向自由度的效果，减少限位结构的设置，降低成本。
作为可变换的实施方式，负离子发生器43可以呈方形或圆柱形设置。
第一限位结构包括一个第二凸出部23，背向风道内壁21凸出设置，第二凸出部23上设置有朝上延伸并与风道内壁21间隔设置的弯折231，纵向柱433适于限位弯折231与风道内壁21之间的区域。第二凸出部23通过设置背向风道内壁21且延伸向上的弯折231，承接负离子发生器43，并对负离子发生器43背向导流罩1和远离风道方向的运动起限位作用。在本实施例中，第二凸出部23为片状，弯折231距风道内壁21的间距与纵向柱433的背向风道与朝向风道两侧间的厚度相同。
作为可变换的实施方式，第二凸出部23可以设置多组，弯折231距风道内壁21的间距可以大于纵向柱433的厚度。
第一限位结构还包括辅助支撑部24，辅助支撑部24设置在第二凸出部23的两侧，辅助支撑部24与第二凸出部23平行设置并支撑横向柱432。这样设置，通过增加对负离子发生器43的承接结构，提升了负离子发生器43安装的稳定性，同时由于在横向柱432上设置辅助支撑部24，对于负离子发生器43 沿横向柱432两侧的运动其到了限位作用，配合第二凸出部23和导流罩1以及风道内壁21固定负离子发生器43。在本实施例中，辅助支撑部24为矩形片，设有两个，且间距与纵向柱433靠近辅助支撑部24两侧间的宽度相同。
辅助支撑部24与定位槽22对应设置。导流罩1上与第一限位结构相对应的部位设置有第二限位结构，第二限位结构适于压覆定位槽22。第二限位结构为第一凸出部11，设于导流罩1底端，朝向横向柱432的方向，第一凸出部11发生朝向导流罩1轴向中心方向的延伸。在本实施例中，第一凸出部11沿靠近导流部2的方向上凸起程度逐渐增大，作为可变换的实施方式，第一凸出部11沿靠近导流部2的方向上凸起程度可以不作变化。
导流罩1设于风道内壁21上方，并压覆定位槽22，对负离子发生器43的发射头431远离导流部2的运动起限位作用，发射头431突出设置于横向柱432上靠近风道的一侧，导流罩1底端设置朝向导流罩1轴向中心方向的延伸的第一凸出部11对横向柱432进行补充限位，提高了负离子发生器43固定结构的稳定性。
作为可变换的实施方式，辅助支撑部24和第一凸出部11以及第二凸出部23可以为块状等。
风道内沿均匀间隔设置有导流叶片25，发射头431设于导流叶片25的间隙。风道内设置导流叶片25，防止空气在风道内产生涡流，损失能量，使气流流通通畅，减小噪音的产生。作为可变换的实施方式，导流叶片25可不作设置。
显然，上述实施例仅仅是为清楚地说明所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引伸出的显而易见的变化或变动仍处于本公开创造的保护范围之中。
