Water filter with double sterilization function

Abstract

The invention relates to a water filter with double sterilization function, which includes a filter element shell and a replaceable inner core assembly. The filter element shell includes a shell body, the upper end of the shell body is provided with a water inlet, and the upper part is provided with a reinforcement module, which is composed of graphene. Packed in a dialysis bag to prevent graphene from leaking out; the lower end of the shell body is provided with a number of water outlet holes, and the inner core assembly is arranged in the shell body; The upper layer of nano-silver filter cloth, the lower end of the core tube is provided with the lower layer of nano-silver filter cloth, the upper layer of nano-silver filter cloth and the lower layer of nano-silver filter cloth limit the filler in the core tube; the bottom of the shell body forms a concave valve installation cavity, the valve installation A regulating valve is arranged in the cavity. The nano-silver on the nano-silver filter cloth can achieve first-level sterilization and long-lasting sterilization; the activated carbon and ion exchange resin in the filler can soften water, remove heavy metals, and adsorb 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...
