Description

一种超薄电晕消毒模块 技术领域
本实用新型涉及空气消毒净化领域，具体涉及一种超薄电晕消毒模块。
背景技术
因新冠疫情的影响，目前越来重视空气消毒，目前空气的消毒通过在无人环境进行消毒，如紫外线、喷洒消毒水等，有人环境随时空气消毒的技术手段较为缺少。
现有的电离技术主要用于除尘除臭，通常电压在8000伏以上，产品厚度在10厘米以上，又因为除尘后易导致电场击穿而使得臭氧超标，普遍存在臭氧超标、产品太厚、有噼啪异响声和难维护的问题。
实用新型内容
本申请提供一种超薄电晕消毒模块，巧妙地将静电催化技术应用于空气消毒，充分利用电晕场的消毒能力，通过生成电晕场实现有人环境的空气消毒，不仅可杜绝臭氧超标，而且无异响、易维护、对人体、设备和环境均安全。

在一些实施例，所述电极针的针尖与金属圆管的进风口之间具有间距为5-10毫米
在一些实施例，所述正极支架与金属圆管间隔大于100毫米。
在一些实施例，所述高压包的电压为4000伏-8000伏，电流为200微安-1毫安。
在一些实施例，所述金属圆管的高度为1厘米-3.6厘米。
在一些实施例，所述电极针的位置，位于金属管内的轴心位置。
在一些实施例，所述进风口至电极针的针尖上方5mm的区域为电晕区，所述电极针的针尖上方5mm至出风口的区域为吸附区。
在一些实施例，所述电晕区为高速旋转的电晕场，对病毒具备强矿化作用。

具体实施方式
下面通过具体实施方式结合附图对本实用新型作进一步详细说明。其中不同实施方式中类似元件采用了相关联的类似的元件标号。在以下的实施方式中，很多细节描述是为了使得本申请能被更好的理解。然而，本领域技术人员可以毫不费力的认识到，其中部分特征在不同情况下是可以省略的，或者可以由其他元件、材料、方法所替代。在某些情况下，本申请相关的一些操作并没有在说明书中显示或者描述，这是为了避免本申请的核心部分被过多的描述所淹没，而对于本领域技术人员而言，详细描述这些相关操作并不是必要的，他们根据说明书中的描述以及本领域的一般技术知识即可完整了解相关操作。
另外，说明书中所描述的特点、操作或者特征可以以任意适当的方式结合形成各种实施方式。同时，方法描述中的各步骤或者动作也可以按照本领域技术人员所能显而易见的方式进行顺序调换或调整。因此，说明书和附图中的各种顺序只是为了清楚描述某一个实施例，并不意味着是必须的顺序，除非另有 说明其中某个顺序是必须遵循的。
参考图1-6，本申请提供一种超薄电晕消毒模块，包括：绝缘围框7、负极孔板4和正极支架6；负极孔板4设置于绝缘围框7底部，负极孔板4上设置有若干个用于安装金属圆管3的安装孔，金属圆管3的底部进风口9固定在负极孔板4的安装孔内，金属圆管3的顶部开口为出风口10。
正极支架6为网格状，正极支架6设置于绝缘围框7顶部、与金属圆管3的出风口10之间有间隔。
每个金属圆管3的轴心正上方悬有电极针5，该电极针5的端部安装在正极支架6的骨架处，电极针5的针尖与金属圆管3的进风口9之间具有间距(以5-10毫米为宜)。
如此设置，使得电极针5的针尖位于金属圆管3内，但离管口(进风口9)又有安全距离，可实现针尖的均匀放电，防制臭氧的发生，针尖和管壁形成有效的电晕层11，即：进风口9至电极针的针尖以上5mm的区域为电晕区。而电极针的针尖以上5mm至出风口10的区域为吸附区12。
在具体实施例，电极针5(放电合金针)与金属圆管3之间形成高速旋转电晕场11，释放大量的正离子和自由基，对通过的病毒实现强矿化消毒，同时大量的正离子会富集在颗粒物上，在库仑力的作用下被吸附区12吸附，从而实现了有人环境的空气消毒。
还需要指出的是，电极针5须严格保持在金属圆管3的轴心位置，这样有利于控制针尖的均匀放电，防止臭氧的发生和保障电晕场效果。
在一些实施例，负极孔板4、正极支架6分别通过绝缘连接柱8与绝缘围框7固定连接。
在一些实施例，负极孔板4与正极支架6平行。
在一些实施例，正极支架6与金属圆管3间隔大于100毫米，以便实现空气绝缘。
绝缘围框7内还设置有外部接电盒1和高压包2，外部接电盒1与高压包2电连接，高压包2的正极和正极支架6电连接，高压包2的负极和负极孔板4电连接。在一些实施例，高压包的电压为4000伏-8000伏，电流为200微安-1毫安，并且在1毫安实现限流，确保对人体触碰的安全。
在上述实施例，金属圆管3的高度为1厘米-3.6厘米，本实例创造性地聚焦消毒能力，弱化除尘能力，严格控制金属圆管3的长度在1-3.6厘米之间，使得 整体产品可以控制在2-6厘米之间，实现了超薄设计。
本申请的超薄设计，是因为本申请的功能聚焦于空气消毒能力，吸附能力方面要求并不高，所以过长的金属圆管和电极针并不能有效增加除尘能力，反而过长的金属圆管在除尘后易导致电场击穿而使得臭氧超标，也增加了维保的难度，更重要的是，过长的管长将导致整体设备变厚，不利于实际环境的使用。而且，在某些重点防疫区域需要达到一次性通过的消毒率90％，可能需要2层设备实现，所以超薄设计变得尤为重要。
因此，本申请的超薄设计使得消毒设备(整体设备薄至2.5厘米)可以适配任何款式的空调，外形设计更美观，可更方便使用的消毒设备，也可以通过多层组合设计出多层超强消毒能力的组合设备。
以上应用了具体个例对本实用新型进行阐述，只是用于帮助理解本实用新型，并不用以限制本实用新型。对于本实用新型所属技术领域的技术人员，依据本实用新型的思想，还可以做出若干简单推演、变形或替换。
