 本发明的实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
实施例一，参照图1—图3所示，本发明提供一种过滤器正电网支撑结构，包括用于固定过滤器内正电网1的支撑架2，以及用来支撑所述支撑架2的支撑柱3，所述支撑架2下表面设有可与所述支撑柱3连接的连接柱4，所述连接柱4的直径小于所述支撑柱3的直径，依借上述技术方案，本发明所提供的过滤器正电网支撑结构，由于所述支撑柱3的直径大于所述连接柱4的直径，致使所述支撑柱3与连接柱4之间形成一个台阶，从支撑柱3底部方向吹来的待处理空气沿着所述支撑柱3外表面向上运动，而其中所携带的灰尘颗粒也就有效避免其存附在所述连接柱4上，保持了所述连接柱4表面的洁净，截断了所述正电网1产生的电流向下放电网5直接放电，避免产生火花，保证了设备安全运转。
优选地，所述支撑柱3呈中空腔体，其上端外缘设有外圆台31，所述外圆台31的内径大于所述连接柱4的外径，所述外圆台31包裹所述连接柱4，进一步地起到了防止待过滤空气中灰尘接触到所述连接柱4的作用，同时由于外圆台31的内径大于所述连接柱4的外径，致使所述连接柱4与所述外圆台31之间形成一条缝隙，由于高压电爬电过程中无法发生多次180度转向的现象，所以当正电网1所释放的高压电顺着所述连接柱4向下爬电时，遇到所述连接柱4与所述外圆台31之间形成的缝隙时便无法跨越，更进一步地避免了所述正电网1与下放电网5产生打火现象。
进一步地，所述连接柱4呈中空腔体，其下端外缘设有向下延伸的外凸台41，所述外凸台41内设有内平台42，所述支撑柱3设有内圆台32，所述内圆台32与外圆台31之间形成环形凹槽33，所述内圆台32支撑所述连接柱4的内平台42，所述连接柱4的外凸台41置于所述环形凹槽33中，所述内平台42下表面到所述外凸台41下表面的垂直距离小于所述内圆台32上表面到所述环形凹槽33底部的垂直距离，也就是说所述外凸台41下表面与所述环形凹槽33之间具有空隙，所述环形凹槽33的宽度大于所述外凸台41的宽度，所述内圆台32高度小于所述外圆台31的高度，使所述环形凹槽33与所述外凸台41之间形成“U”型或者“L”型的空隙，进一步阻止了所述正电网1的高压电流顺着所述连接柱4向下爬电，所述外圆台31高于所述内圆台32的设计能够进一步防止待净化空气所携带的灰尘进入所述环形凹槽33。
进一步地，所述连接柱4与所述支撑柱3的空腔内穿设可将两者固定在下放电网的螺栓7，所述螺栓7的顶帽卡在所述连接柱4的内平台42上方，所述螺栓除了能够连接固定所述连接柱4和所述支撑柱3以外，还能够将所述连接柱4与所述支撑柱3定位对准，致使所述环形凹槽33与所述外凸台41之间的空隙形成“U”型。
所述支撑架2上表面设有正电网1固定柱21，所述正电网1盘绕在所述固定柱21上，所述正电网1通过密封连接头6与高压电源连接，所述正电网1设于所述支撑架2上方方便清洁所述正电网1上所吸附的灰尘。
实施例二，参照图4所示，本实施例所提供的过滤器正电网支撑结构具有上述实施例一所述的技术特征，进一步地将所述支撑柱3设计为呈椎体，所述支撑柱3上端直径大于下端直径，当待净化空气从下端向上端运动时，被所述支撑柱3外侧表面导向，从而使待净化空气向所述支撑柱侧边运动，进一步防止待净化空气所携带的灰尘粘附到所述连接柱4表面。
实施例三，参照图5所示，本实施例所提供的过滤器正电网支撑结构具有上述实施例一所述的技术特征，进一步地在所述支撑柱3外表面设有空气导向装置34，对待净化空气进行导向，从而保护所述连接柱4不被待净化空气中的灰尘颗粒粘附，本实施例中优选设计为所述空气导向装置34为截面呈三角形的环形，本实施例中所述空气导向装置34还可以设计为漏斗状的导向圈，其漏斗形的底部套于所述支撑柱3的外表面，上端呈喇叭口开放，同样起到将待净化空气导向所述支撑柱3外侧，保护所述连接柱4不受灰尘粘附。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
