Abstract (en)

The present invention provides a dust collection electrode assembly, an air purification device and a control method thereof. The dust collection electrode assembly includes a dust collection electrode (21) and a dust collection electrode support structure, the dust collection electrode is moveable relative to the dust collection electrode support structure to change a position and/or orientation state of the dust collection electrode relative to a generation electrode assembly (1). By changing the position and/or orientation state of the dust collection electrode relative to the generation electrode assembly, the main dust accumulation area of the dust collection electrode (21) can be changed. When there is more dust accumulated in a certain area, the position or orientation state of the dust collection electrode (21) can be changed, so as to change to another area to accumulate dust, thereby effectively reducing the cleaning frequency, slowing down the attenuation of the particulate matter CADR of the purification device, and optimizing the user experience.
