The present invention provides a pulsator structure and a clothing processing device, wherein the pulsator structure comprises: a pulsator having a stirring blade; a pulsator disc having an opening adapted to the stirring blade, the pulsator disc being inserted on the stirring blade through the opening, and being able to move up and down relative to the stirring blade. The pulsator disc of the present invention can move up and down along the stirring blade, thereby changing the height of the stirring blade relative to washing water and washings. If the pulsator disc moves to a lower position on the stirring blade, the stirring blade is at a higher height relative to the washing water and washings, has a greater stirring force, generates a stronger water flow, and the washings are fully stirred, thereby improving the washing ratio. When the pulsator disc moves to an upper position on the stirring blade, the stirring blade is at a lower height relative to the washing water and washings, and the stirring is gentler, thereby achieving gentle washing of the clothes, avoiding deformation and damage of the clothes, and improving the protective effect of the clothes. Moreover, the driving force required for the stirring blade is smaller, thereby reducing the energy consumption of the product, and achieving energy saving and power saving.
