Valve core

A valve core, comprises:

• a housing having a hollow cavity;
• a valve assembly installed below the housing, wherein the valve assembly is provided with a water inlet, a water crossing port, a first water outlet, and a second water outlet;
• a switching component, wherein the switching component extends through the hollow cavity and the valve assembly, and the switching component is movably arranged on the water inlet or the water crossing port or the second water outlet;
• a control mechanism arranged in the hollow cavity, wherein a first end of the control mechanism passes through a top portion of the housing and a second end of the control mechanism is biased against the switching component;
• and
• a marble arranged between the switching component and the control mechanism, wherein the control mechanism is operated to drive the marble to push the switching component, such that the water inlet communicates with the first water outlet and/or the second water outlet;
• wherein, the control mechanism comprises a valve stem and a lifting component arranged below the valve stem, the valve stem is provided with N pieces of first fan blades at an end proximal to the lifting component, N=2n, wherein nis an integer and n≥1;
• the lifting component is provided with K pieces of second fan blades at an end proximal to the valve stem, K=2 or K=2k+1, wherein k is an integer and k≥.
