The filter of the utility model is composed of a roller for cleaning filtering materials, a roller for contaminated filtering materials, filtering materials, a driving motor, a time relay and a brush.
本实用新型的过滤器由清洁滤料滚筒、已污染滤料滚筒、滤料、驱动电机、时间继电器和刷子组成。
As the brush body replaces the elastic strip, the contact area is increased with the charging roller, and the cleaning effect on the charge roller is relatively improved.
由于采用了刷体替代了弹性片，增加了与充电辊的接触面积，可相对提高对充电辊的清洁效果。
