Abstract:
A functional filter element (100), comprising an upper cover (1), a filter element (2), and a lower cover (3). The filter element (100) is used for filtering water and adding taste-improving substances, and has a hollow penetrating structure. The lower cover (3) and the upper cover (1) are combined to accommodate the filter element (100). A column (3-1) having the upper end opened is integrally provided at the bottom of the lower cover (3), such that the column (3-1) penetrates through the hollow penetrating structure to realize close fit. An inwardly-recessed structure is provided at the bottom of the lower cover (3) and extends into the column to be connected to the opening. The inwardly-recessed structure is configured to be tightly matched with a water supply pipe to achieve water supply. When the filter element filters water, health-enhancing and taste-improving substances are released, such that the pH value of the water is balanced.
