Abstract

A valve core which includes a housing, a valve assembly arranged below the housing, a switching component, a control mechanism, and a marble. The valve assembly is provided with a water inlet, a water crossing port, a first water outlet, and a second water outlet. The switching component is movably arranged at the water inlet or the water crossing port or the second water outlet. An end of the control mechanism passes through a top portion of the housing, and another end thereof is biased against the switching component. Operating the control mechanism, the marble is driven to push the switching component, so that the water inlet is connected to the first water outlet and/or second water outlet to form two water passages. The control mechanism includes a valve stem and a lifting component, and the marble is arranged between the lifting component and the switching component.
