Filter assembly, and filter core structure provided with filter assembly

Abstract

The invention provides a filter assembly. The filter assembly comprises a filter material module group, a water outlet connection seat, a filter material installation seat, and a filter core structureprovided with the filter assembly; the top side of the filter material module group is provided with a raw water input end and a pure water input end, and the bottom side is provided with a waste water output end; the water outlet connection seat is arranged on the top side of the filter material module group; the water outlet connection seat is provided with a raw water inlet corresponding to the raw water input end, and is provided with a pure water outlet corresponding to the pure water input end; the filter material installation seat is arranged on the bottom side of the filter material module group, and is provided with a waste water outlet corresponding to the waste water outlet end; the waste water outlet is provided with a single way water guide valve used for guiding single way discharging of waste water; adoption of the filter core structure is capable of solving corresponding water purifying device initial discharged water TDS exceeding standard problem, and ensuring user drinking water health.

Description

technical field [0001] The invention relates to the technical field of water purification equipment, in particular to a filter assembly and a filter core structure using the same. Background technique [0002] The water purifier in the prior art may be filtered with a reverse osmosis filter element. After the water purifier is shut down for a long time, the water in the reverse osmosis filter element that is originally on the raw water or concentrated water side will flow to the pure water of the membrane. When the water end permeates, the high TDS solutes on the concentrated water side of the diaphragm will also infiltrate into the pure water side, resulting in a higher TDS at the pure water end; then when the water purifier is discharged again, the TDS will exceed the standard. Contents of the invention [0003] The object of the present invention is to provide a filter assembly and a filter core structure using the same to overcome the shortcomings of the prior art. ...
