NOVELTY - The utility model relates to the technical field of cell filtering, and claims a double-layer cell filtering filter core, comprising a first shell, the inner part of the first shell is detachably provided with graphene filling layer, the first shell top part connected with a second shell, the inner part of the second shell is provided with a first filter screen, the bottom of the first shell is provided with a third shell, the inner part of the third shell is provided with a second filter screen, the first shell and the second shell third shell are connected by a connecting mechanism, the connecting mechanism comprises a pin rod fixedly installed on the surface of the second shell and the third shell, the surface of the pin rod is movably sleeved with a connecting plate. The double-layer cell filter core has good filtering effect, it greatly increases the filtering effect and is convenient to clean, it solves the problem that the filter core of the common cell filter can only be single filter, the filtering effect of the cell is not good, it needs to repeatedly filter for many times, the problem of the efficiency is affected.
