Water filter with double sterilization function

Abstract

The invention relates to a water filter with a double sterilization function. The water filter comprises a filter element shell and a replaceable inner core assembly. The filter element shell comprises a shell body. A water inlet is formed in the upper end of the shell body, and a strengthening die block is arranged at the upper portion of the shell body and made of graphene, and the graphene is packed through a dialysis bag to be prevented from leaking. A plurality of water outlet holes are formed in the lower end of the shell body, and the inner core assembly is arranged in the shell body. The inner core assembly comprises a core tube which is through vertically, and the core tube is filled with padding. Upper-layer nano-silver filtering cloth is arranged at the upper end of the core tube, lower-layer nano-silver filtering cloth is arranged at the lower end of the core tube, and the upper-layer nano-silver filtering cloth and the lower-layer nano-silver filtering cloth are used for limiting the padding into the core tube. Nano-silver on the nano-silver filtering cloth can be used for achieving first-level sterilization and achieving lasting sterilization; active carbon and ion exchange resin in the padding are used for achieving the functions of softening water, removing heavy metal and adsorbing pesticides and residual chlorine.

Description

technical field [0001] The invention relates to a water filter with double sterilization functions. Background technique [0002] Tap water refers to the water that is purified and disinfected by tap water treatment plants and meets the corresponding standards for people's living and production use. Domestic water is mainly drawn from rivers, lakes, groundwater, and surface water through the water intake pumping station of the water plant, and the water plant is processed by the water plant in accordance with the "National Domestic Drinking Water Relevant Hygienic Standards" through processes such as sedimentation, disinfection, and filtration, and finally passes through the water distribution pumping station sent to each user. [0003] Most of the disinfection of tap water now adopts the chlorination method. The main purpose of chlorination of public water supply is to prevent water-borne diseases. This method has been promoted for more than 100 years. It has relatively co...
