AI Technical Summary
Technical Problem
Existing household air purifier filters are difficult to clean after pollutants accumulate during use, resulting in reduced filtration efficiency and increased costs. At the same time, traditional cleaning methods can easily cause air pollution.
Method used
It uses an ion emitter and a controllable potential adsorption element. The pollutants are charged by ion collision and adsorbed on the filter element. When in use, the adsorption element is in a neutral state. When cleaning, it switches to the opposite potential to adsorb pollutants, thus avoiding air pollution.
Benefits of technology
It enables automatic cleaning of the filter element, extends its service life, maintains the filtration effect, avoids air pollution, and reduces user costs.

Abstract
本申请涉及一种净化结构和净化装置，包括：壳体，开设有相互连通的进气口和出气口；滤芯，位于进气口与出气口的连通路径上；离子发射器，可受控地朝向滤芯在靠近进气口的一侧发射离子；吸附件，设置于壳体内，当吸附件处于第一状态时，吸附件具有中性或与离子极性相同的电位，当吸附件处于第二状态时，吸附件具有与离子极性相反的电位。气体从进气口运动至出气口的过程中，气体中污染物首先会与离子发射器的离子相互碰撞，并带上与离子相同的电荷被吸附在滤芯上。之后可以控制吸附件处于第二状态，滤芯上的污染物会被吸附件所吸引，并从滤芯脱离并吸附在吸附件上，从而避免污染物堆积在滤芯上，起到清理滤芯的效果。
