Title: WATER FILTRATION SYSTEM
Abstract:
A water filtration system (100), comprising a raw water inlet (100a), a pure water outlet (100b), a clean water outlet (100c), a waste water outlet (100d), and an integrated filter element (1). The integrated filter element (1) comprises a front filter element, a fine filter element, and a rear filter element, and has a first interface (10a), a second interface (10b), a third interface (10c), and a fourth interface (10d). The first interface (10a) is connected to the raw water inlet (100a). The second interface (10b) is connected to the pure water outlet (100b). Both the clean water outlet (100c) and the waste water outlet (100d) are connected to the third interface (10c). Raw water entering from the raw water inlet (100a) is filtered by the front filter element, the fine filter element, and the rear filter element in sequence, and flows out of the pure water outlet (100b). The raw water entering from the raw water inlet (100a) flows out of the clean water outlet (100c) only through the front filter element. At least one of a flow passage connected to the pure water outlet (100b) and the fourth interface (10d) is provided with a water storage device (2).
