This creation relates to a shunted liquid filter that is free of floating impurities, large amounts of fine impurities, and/or coarse particles with a relatively high specific gravity.

Press, the common liquid filter on the market is a sedimentation filter or mesh (filter or filter) filter; the sedimentation filter is the difference in the specific gravity of the transmitted substance, and the substance with a higher specific gravity is precipitated to the bottom, usually only Filtering out coarse-grained impurities with heavier specific gravity is not suitable for floating impurities or fine impurities in the liquid in many occasions.

In addition, the general form of mesh filter is to filter a large amount of impurities through the filter or filter paper. Because a large amount of impurities will quickly accumulate on the filter mesh and cause clogging, the filter or filter paper has a short service life and must be frequently maintained or replaced. Filter or filter paper, often due to mesh cleaning or filter/filter material replacement frequency is too high, resulting in a large number of users work load or excessive consumption of filter or filter material costs; in addition, there is a combination of precipitation filter and mesh filter The system or device, although the sedimentation filter is used in the pre-filtration operation, can reduce the burden of filtering impurities of the rear mesh filter. However, a large amount of swarf and fine debris floating in the impurities still cause a considerable degree of blockage on the filter mesh.
