Document Type and Number:
WIPO Patent Application WO/2022/082914
Kind Code:
A1
Abstract:
A valve core (2) structure, a faucet (27) and a driving system. The structure comprises a rotating member (10), a fixing member (9) and a bottom plate (40), wherein the fixing member (9) and the bottom plate (40) are stacked one above the other, with two water inlets (11, 12) and a water outlet (13) which penetrate the fixing member (9) and the bottom plate (40) being formed, and a one-way valve being provided at one water inlet (11). The rotating member (10) is located on the side of the fixing member (9) away from the bottom plate (40); a groove (8) capable of realizing communication between the two water inlets (11, 12) and closing the water outlet (13) is formed in the rotating member (10); and the one-way valve is used for realizing one-way communication between the two water inlets (11, 12). A spring (37) of a one-way valve and a sealing cap (4) thereof are arranged in a water inlet of a valve core (2), such that the cost is low, and one-way flow of water flows in a hot water output direction, thereby overcoming the disadvantage of cold water being mixed therewith.
