Electric air collecting filter of air purifier

The electric dust collecting filter for air purifier includes mainly ionizing part to ionize dust in air, earth wire net to adsorb ionized dust, the collecting electrode to adsorb the ionized dust, the accelerating electrode to accelerate the ionized dust towards the collecting electrode and with the first insulating matter coated to the surface, and the collecting part with the second insulating matter set separately between the collecting electrode and the accelerating electrode. The electric dust collecting filter in the said structure can prevent the lowered dust collecting efficiency caused by the damage in the first insulating matter and prolong the service life. 一种空气净化器的电式集尘过滤器，包括电离部、收集电极、加速电极和收集部。电离部对空气中的灰尘进行电离；收集电极吸附在电离部内被电离的灰尘；加速电极使在电离部内被电离的灰尘向着收集电极进行加速，该加速电极表面上涂覆有第1绝缘物质；其特征在于，收集部包括有第2绝缘物质，第2绝缘物质分离设置在收集电极和加速电极之间。这种结构的电式集尘过滤器可以防止由于第1绝缘物质的绝缘破坏而导致的集尘效率降低，也延长了使用寿命。
