Ceramic valve core assembly and a self-cleaning ceramic valve core

A self-cleaning ceramic valve core comprising a ceramic valve core assembly, wherein the ceramic valve core assembly comprises a fixed valve plate and a movable valve plate, the movable valve plate is rotatable and is slidably attached on the fixed valve plate, the fixed valve plate comprises a first cold water inlet, a first hot water inlet and a first water outlet, the movable valve plate comprises a first water inlet and a second water outlet, and wherein the first water outlet communicates with the second water outlet to form a water outlet channel, the first water inlet comprises a water mixing cavity and a filter mounting cavity having a filter member mounted therein for filtering impurities;

• the filter mounting cavity and the water mixing cavity are in communication with each another and are arranged sequentially from top to bottom, so as to allow filtered impurities to accumulate in the water mixing cavity;
• wherein by rotating the movable valve plate, the first cold water inlet, the first hot water inlet, or both the first cold water inlet and the first hot water establish communication with the water mixing cavity;
• a lower edge of the second water outlet contacts an upper edge of the first water outlet, thus by moving the movable valve plate away from a water inlet side of the fixed valve plate, a water passage formed by the first cold water inlet, the first hot water inlet, the water mixing cavity and the first water outlet is established;
• wherein the movable valve plate is laterally moveable relative to the fixed valve plate for directly connecting the water mixing cavity to the first water outlet, and thereby allowing the impurities accumulated in the water mixing cavity to be flushed through the first water outlet.
