Background

Micro-plastics, micro-fibers, usually fibers or particles with a size below 5mm, are increasingly polluting the marine environment. Due to the characteristics of small volume and large specific surface area, the micro plastic and the micro fiber have strong pollutant adsorption capacity. The micro-plastics and the micro-fibers are similar to the riding of marine pollutants, and are very easy to be ingested by marine organisms in the process of wandering in the sea after the micro-plastics, the micro-fibers and the marine pollutants are combined, so that the marine ecosystem can be directly harmed, and the micro-plastics and the micro-fibers can enter human bodies through ecological circulation to generate great threat to the health of human beings when the human beings stand at the top end of a food chain.

Referring to the study of the ecological impact research center of coastal cities of sydney university, one of the main sources of micro-plastics and micro-fibers in the ocean is the wastewater discharged from washing machines. As research indicates, 1900 tiny fibers are washed away when washing a piece of clothes, and on the premise that washing machines are widely used in the world and the washing frequency is generally high, how to avoid the discharge of tiny plastics becomes a technical problem to be solved urgently.

And when the washing machine is provided with both the coarse filter and the micro fiber filter, since a water pump is generally disposed between the two filters, as shown in fig. 1, a water container 11 'of the washing machine is communicated with a circulation water pipeline 12', a coarse filter 14 ', a water pump 18', a drain valve and a micro fiber filter 15 'are sequentially disposed along a water flow direction of the circulation water pipeline 12', and the circulation water pipeline 12 'is communicated with a drain pipeline 16' through the drain valve. Because be equipped with the water pump between coarse filter and the microfiber filter, consequently need set up a plurality of installing ports on the washing machine shell to dismantle the filter one by one, not only reduced the structural strength of washing machine shell, influenced the pleasing to the eye of washing machine shell, still increased the time of dismantling the clearance, reduced change efficiency.
