随着人们生活水平的提高， 人们对环保健康的需求也不断提高， 开发 高性能的空气净化器来净化室内空气、 优化室内环境迫在眉睫， 离子风净 化器也越来越广泛地应用于日常生活中。
空气经过进风口的初过滤网达到发生极， 发生极在高压作用下， 形成 等离子场. 空气中的细菌和病毒通过等离子场时，表面的蛋白质结构被破坏 而消灭。 甲醛等有害的有机分子， 在高能电子和强氧化性的自由基的作用 下， 分解成水和二氧化碳。发生极的高压电场使得部分空气带上电荷， 并在 电场力的作用下运动， 与空气中的灰尘颗粒碰撞并使颗粒带电，如滚雪球效 应,越来越多的空气颗粒带上了电荷， 当带电颗粒运动到带相反电荷的收集 极附近时， 由于静电吸附作用被收集极吸附， 漏掉的带电颗粒到达带同样 电荷的排斥极， 由于同性电荷的排斥作用， 被推回收集极， 从而将颗粒清 除效果提高到 99%以上， 而且等离子场产生的等离子风， 不需借助风机就 可以产生足够大的风速循环室内空气， 达到无声节能的效果。
一种典型的离子风净化器包括进风口、 出风口， 以及设置于进风口和 出风口之间的发生极和收集极， 发生极与收集极模块（包括收集极和排斥极 组)相对设置。
由上述工作过程可知， 收集极是离子风净化器的核心部件之一， 进入 净化器中的灰尘颗粒要吸附在收集极的表面才能够实现净化， 因此， 收集 极的吸附效果直接影响到离子风净化器的净化效率， 进而影响离子风净化 器的使用性能。
因此， 提高收集极的吸附能力， 从而提高离子风净化器的净化效率， 提高其使用性能， 就成为本领域技术人员亟需解决的问题。
另外， 目前，一般的净化器釆用高效空气过滤器 (HEPA， High Efficiency Particulate Air Filter)或者水洗等物理技术进行空气净化， 这样对可吸入颗粒 物的去除效率非常有限， 而且 HEPA过滤网其吸附效果随时间变化， 灰尘 堆积后， 衰减非常严重。 因此， 为了解决以上净化器的不足， 现在的高压 等离子或者高压静电除尘器受到客户更多地关注。
但是， 高压离子净化器容易出现高压放电现象， 这样在使用过程中， 有必要对高压放电现象进行监测并实时进行保护。
净化器放电： 高压离子净化器工作的时候， 存在一个空间高压， 当高 压电场中飞入较大颗粒的灰尘、 毛屑等颗粒物时候， 改变瞬间电场的特性， 就会产生噼啪噼啪放电声， 称净化器放电。
净化器放电时产生噪声影响到消费者的使用感受， 同时持续放电也导 致安全的隐患， 所以要在轻微放电的时候进行侦测并作及时处理， 如根据 放电情况及时调整电场大小， 可避免持续放电发生。
现在， 对于高压放电现象的监测主要有两种方式。
第一种方式： 直接安装漏电保护器。 该漏电保护器可以检测到极端情 况， 即当放电持续恶化到接近短路状态时才能检测出来， 相当于做短路检 测。
显然， 这种放电检测起不到很好的保护作用， 当高压放电不是持续性 的， 而是间断性时， 无法检测出放电进而无法及时进行保护。
第二种方式： 仅对放电信号直接进行检测， 当放电信号高于一定基准 信号时， 才实施放电保护。 但是一般放电信号比较微弱， 这种保护方式仅 能在产生剧烈放电时， 才能进行有效的保护。
针对高压离子净化器如何提供一种放电监测保护电路， 能够有效及时 地对放电进行监测保护是本领域技术人员需要解决的一个技术问题。 发明内容

本发明的核心是提供一种离子风净化器， 其收集极具有较强的吸附能 力， 从而提高了等离子风净化器的净化效率， 提高了其使用性能。
为了使本技术领域的人员更好地理解本发明的技术方案， 下面结合附 图和具体实施方式对本发明作进一步的详细说明。
请参考图 1至图 3;图 1为本发明所提供的收集极第一实施例的示意图； 图 2为本发明所提供的收集极第二实施例的示意图； 图 3为本发明所提供 的收集极第三实施例的示意图。
在一种具体实施方式中， 本发明所提供的离子风净化器包括相对设置 的发生极和收集极， 发生极与收集极之间具有电位差， 且收集极的各收集 极板 1上均设置有至少一个第一凸起部 11，该第一凸起部 11具有光滑表面； 这样， 通过第一凸起部 11的设置增加了收集极的吸附面积， 提高了收集极 的吸附能力， 从而提高了等离子风净化器的净化效率， 提高了其使用性能。
上述第一凸起部 11的形状可以为圓形， 也可以为其他具有流线型表面 的形状， 例如椭圓形或者翼型等。 第一凸起部 11可以为双向凸起， 即在收 集极板 1的两侧均具有凸起结构， 也可以为单向凸起， 即在收集极板 1的 单侧具有凸起结构。 第一凸起部 11可以为如图 1和图 2所示的实心结构， 也可以为如图 3 所示的空心结构。
上述第一凸起部 11可以设置多个， 各第一凸起部 11可平行设置， 也 可以略有倾斜设置；各第一凸起部 11可以沿直线延伸，也可以沿弧线延伸， 甚至也可以是表面光滑的凸点。
上述第一凸起部 11可以沿收集极板 1的宽度方向延伸， 显然地， 第一 凸起部 11也不局限于该方向延伸， 也可以倾斜适当的角度。
上述第一凸起部 11进一步包括外凸起部和内凸起部， 所述外凸起部和 所述内凸起部沿收集极板 1 的平行于发生极的方向布置， 且外凸起部位于 内凸起部的外侧， 外凸起部的凸起高度大于内凸起部的凸起高度， 内凸起 部设置的目的是为了不让空气在通过电场时流通过快， 以便于电场把空气 中的颗粒都捕捉在收集极板上。
"外侧"是指收集极板迎风的一侧， "内侧"是指收集极板背风的一侧。 内凸起部可以为多个， 各内凸起部凸起高度可以相等， 也可以不等。 需要指出的是，文中所述"第一、第二"等序数词是为了区分相同名称的 不同结构， 不表示某种顺序， 也不应理解为任何限定。
请参考图 4和图 5，图 4为本发明所提供的排斥极第一实施例的示意图； 图 5为本发明所提供的排斥极第二实施例的示意图。
在上述具体实施方式中， 本发明所提供的离子风净化器还包括排斥极， 该排斥极的排斥极板 2与收集极板 1相间布置， 且排斥极与发生极的带电 性质相同； 排斥极起到的作用是把收集极漏掉的带电颗粒再次推回收集极， 从而提高离子风净化器的一次过滤效率。
在排斥极的排斥极板 2上具有至少一个第二凸起部 21， 第二凸起部 21 的外表面光滑， 以便增加排斥极的面积， 从而将更多的非带电颗粒子推回 收集极， 进而进一步提高离子风净化器的过滤效率。 上述第二凸起部 21的形状可以为圓形， 也可以为其他具有流线型表面 的形状， 例如椭圓形或者翼型等。 第二凸起部 21可以为双向凸起， 即在排 斥极板 2的两侧均具有凸起结构， 也可以为单向凸起， 即在排斥极板 2的 单侧具有凸起结构。 第二凸起部 21可以为如图 4所示的实心结构， 也可以 为如图 5所示的空心结构， 当其为空心结构时， 可以通过排斥极板 2板材 冲压卷边制作。
上述第二凸起部 21可以设置多个， 各第二凸起部 21可平行设置， 也 可以略有倾斜设置；各第二凸起部 21可以沿直线延伸，也可以沿弧线延伸， 甚至也可以是表面光滑的凸点。
上述第二凸起部 21可以沿排斥极板 2的宽度方向延伸， 显然地， 第二 凸起部 21也不局限于该方向延伸， 也可以倾斜适当的角度。
上述第二凸起部 21也可以进一步包括外凸起部和内凸起部， 所述外凸 起部和所述内凸起部沿排斥极板 2 的长度方向布置， 且外凸起部位于内凸 起部的外侧， 外凸起部的凸起高度大于内凸起部的凸起高度， 内凸起部设 置的目的是为了不让空气在通过电场时流通过快， 以便于电场把空气中的 颗粒都充分推向收集极板上。
内凸起部可以为多个， 各内凸起部凸起高度可以相等， 也可以不等。 相邻排斥极板 2 与收集极板 1 之间的电位差与两者间距的比值小于 le7V/m, 一般的， 相邻排斥极板 2与收集极板 1之间的距离小于 100mm， 以保证排斥极与收集极之间的电场具有足够的强度。
各收集极板 1 之间的连接方式可以为点导电胶连接， 通过点导电胶把 所有收集极板连接在一起， 从而每根收集极都拥有相同的电性； 各收集极 板 1 之间的连接组件也可以包括金属条和设置于金属条内的弹簧片， 即通 过一个带弹簧片的金属条， 把各个收集极板 1 连接起来， 并带上相同的电 性。 所述收集极板 1和所述排斥极板 2均为铝材或者不锈钢等可成行金属 时， 第一凸起部 11可以通过冲压铝挤工艺形成于所述收集极板 1， 所述第 二凸起部 21可以通过冲压铝挤工艺形成于所述排斥极板 2。
上述收集极的安装方式同样适用于排斥极， 在此不再赘述。
请参考图 6，图 6为本发明所提供的绝缘套一种具体实施方式的结构示 意图。
收集极和所述排斥极通过包裹于两者外的绝缘套 3 连接， 该绝缘套 3 具有镂空结构， 即在绝缘套 3 上开设有通透的槽， 这样在清洗收集极模块 时， 水可以更容易地沿着收集极板 1直接流走， 收集极更容易干燥， 减少 收集极板 1清洗后晾干的时间； 且该绝缘套 3的安装孔内设置有若干凸点， 凸点与收集极和排斥极卡装， 以便提高收集极与排斥极的安装可靠性。 设 置若干凸点是为了保证安装收集极和排斥极时， 通过点接触安装固定而不 是面接触安装， 使得安装更顺畅； 同时， 点接触方式， 排斥极板 2上带电， 可以增加电压的爬电 巨离。
如图 3和图 5所示， 上述收集极的收集极板 1上设置有第一^ ^块 12， 排斥极的排斥极板 2上设置有第二卡块 22， 用来进行收集极板 1和排斥极 板 2的弯折安装。
上述收集极板 1 是通过铝挤模具加工出来后， 切出需要的长度， 然后 通过冲压模具切出第一卡块， 用来折弯安装； 上述第一凸起部 11可以通过 铝挤模具加工， 也可以通过冲压模具制成原始的收集极板 1 形状， 然后 冲压并做卷边加工出来； 排斥极板 2 同样通过冲压模具冲压、 卷边并形成 第二卡块。 排斥极板上有多个圓筒形状， 工艺是铝挤加工而后再切端面得 到的。
参见图 8，该图为本发明提供的高压离子净化器上的放电监测保护电路 实施例一示意图。 本实施例提供的高压离子净化器上的放电监测保护电路， 包括： 釆样 模块 300、 釆样保护模块 300a、 输出保护模块 302、 整形模块 305、 比较放 大模块 307和控制器 100;
所述釆样模块 300挂接在高压离子净化器负载等离子电场 200的正负 两端， 用于釆样等离子电场 200的放电信号；
所述釆样模块 300直接挂载在等离子电场 200的两端， 与一般釆样方 式相比， 提高了釆样的灵敏度和实时性， 这样可以更及时地监测到等离子 电场 200放电的发生， 并在放电的瞬间做出快速响应， 避免产生噼啪放电 声及发生危险状况。
所述釆样保护模块 300a串联在所述釆样模块 300的两端；
需要说明的是，所述釆样保护模块 300a可以由一个快速稳压管来实现， 这种稳压管响应速度快， 瞬间功率大。
当等离子电场 200发生放电异常状况时， 高压电场有很大的波动， 利 用釆样保护模块 300a能够防止高压波动的浪涌电流对釆样模块 300的直接 冲击。
所述输出保护模块 302与所述釆样模块 300并联， 用于对所述釆样模 块 300进行限压； 避免釆样模块 300受到高压电场的直接损伤。
所述整形模块 305，用于将所述釆样模块 300釆样的放电信号进行整流 后输送给所述比较放大模块 307的第一输入端；
由于放电信号是交变信号， 因此所述整形模块 305将交变信号进行整 形翻转， 将交变信号整形为直流信号， 以防止对前后器件的软损伤； 由于 交变信号有时为正， 有时为负， 这样对电气元件的冲击比较大， 时间长了 容易损伤元件的寿命。 同时也有效利用釆样的放电信号的输出能效； 因为 如果不进行整形， 负的脉冲信号就不能被识别， 只能识别出正的信号。 最 大限度提取等离子电场 200的放电特性。 所述比较放大模块 307 的第二输入端连接基准信号， 所述比较放大模 块 307将所述放电进行和基准信号进行比较， 将比较结果进行放大后输出 给控制器 100;
本实施例中的比较放大模块 307 兼具比较和放大的功能， 将二者结合 一起， 减少了信号的衰减。 传统方式往往将放大和比较放置于两个或者两 个以上的集成电路中， 这样对信号产生很大的衰减。 本实施例中釆用一个 集成电路的单独子功能模块， 减少了信号的衰减， 从而能够检测到更微小 的放电信号。
所述控制器 100，用于由所述比较结果控制所述等离子电场 200的大小。 本实施例提供的放电监测保护电路， 将釆样模块直接挂接在负载两端， 直接测试负载两端的放电信号， 并且对放电信号进行无衰减的比较和放大， 这样可以监测负载两端比较微小的放电信号。 不像现有技术那样， 只能监 测剧烈放电或者短路放电。 并且， 本发明提供的电路对于釆样模块进行了 双重保护， 避免放电信号对于釆样模块的冲击。 因此， 本发明提供的电路 可以实时监测微弱的放电信号， 避免放电的持续发生而发生异常。
参见图 9，该图为本发明提供的高压离子净化器上的放电监测保护电路 实施例二示意图。
本实施例提供的高压离子净化器上的放电监测保护电路， 还包括连接 在所述整形模块输出端的衰减阻止器 308;
所述衰减阻止器 308， 用于阻止输送给所述控制器的比较结果反向泄 露。
优选地， 所述衰减阻止器 308可以釆用二极管。
衰减阻止器 308可以阻止输出给控制器 100的信号 310的反向泄露， 同时可以减少其他周围器件对信号 310 的干扰衰减效应。 同时， 衰减阻止 器 308对脉宽信号进行保持， 给控制器读取放电信号留有足够的时间空间。 本实施例提供的电路， 还可以包括连接在所述衰减阻止器 308和所述 控制器 100之间的脉宽拓展模块 309;
所述脉宽拓展模块 309，用于将所述比较结果进行脉冲拓展后发送给所 述控制器 100。
首先介绍一下脉宽拓展， 由于高压放电是瞬时的， 故釆样电路得到的 信号是一个时间宽度在微秒（us )级别的脉冲信号， 微秒（us )级别的脉宽 信号不便于控制器的信息釆集和读取， 故釆取将脉宽宽度进行时间上的放 大， 从微秒（us )级别变为毫秒（ms )级别的硬件处理过程叫做脉宽拓展。
脉宽拓展模块 309将监测到的微小放电信号进行脉宽调制， 可以使控 制器检测识别到微弱的放电信号。 因为微小信号如果不进行脉宽调制， 控 制器将很难识别， 这也是现有技术中的放电检测电路不能检测微弱放电信 号的另外一个原因。
所述脉宽拓展模块 309是一个等同于阻容器的电路， 利用充放电时间 的延迟特性， 达到调制脉宽的作用， 输出脉宽拓展后的信号 310。
本实施例中， 所述输出保护模块包括两个电阻， 分别是第二电阻 301 和第三电阻 303，
所述第二电阻 301连接在所述等离子电场 200的正端和所述釆样模块 300之间；
所述第三电阻 303连接在所述等离子电场 200的负端和所述釆样模块 300之间。
需要说明的是， 所述输出保护模块也可以包括多个串联的电阻， 也可 以为一个电阻。 下面介绍本发明实施例提供的一种脉宽拓展模块的具体实 现方式。
参见图 10， 该图为本发明提供的脉宽拓展模块示意图。
本实施例提供的所述脉宽拓展模块包括并联的第一电阻 R1 和第一电 容 CI ;
所述脉宽拓展模块 309 的输出端连接第一电阻 R1 的一端和第一电容 C1的一端， 所述第一电阻 R1的另一端和第一电容 C1的另一端均接地； 需要说明的是， 脉宽拓展模块 309的输出端既连接衰减阻止器 308的 输出端又连接控制器 100的输入端。
所述脉宽拓展模块的输出端连接所述控制器。
本发明实施例中所述整形模块可以优先选择为二极管或者整流桥。 需要说明的是， 所述基准信号由硬件进行逻辑计算获得或者由所述控 制器提供。
需要说明的是， 所述釆样保护模块为保护箝位元件。
需要说明的是， 所述釆样模块为预设精度的电阻。 一般该釆样模块可 以釆用精度大于 5%的无感电阻。
需要说明的是， 本发明实施例提供的比较放大模块 307是个高精度快 速比较器件， 比如输入脉冲峰值是 0.8伏， 基准信号是 0.7伏， 那么比较放 大模块 307输出将是一个高电平， 在输出端进行上拉电位比如 5V， 就可以 直接输出高电压脉冲峰值可以达到 5V， 然后经 309脉宽拓展， 即可得到一 个 ms级别时间跨度的 5V信号。
以上所述， 仅是本发明的较佳实施例而已， 并非对本发明作任何形式 上的限制。 虽然本发明已以较佳实施例揭露如上， 然而并非用以限定本发 明。 任何熟悉本领域的技术人员， 在不脱离本发明技术方案范围情况下， 都可利用上述揭示的方法和技术内容对本发明技术方案做出许多可能的变 动和修饰， 或修改为等同变化的等效实施例。 因此， 凡是未脱离本发明技 等同变化及修饰， 均仍属于本发明技术方案保护的范围内。
