Press type valve core

A press type valve core comprising:

• a case having a first end and a second end, said case having a first water outlet at each of two sides of said case, the second end of said case communicating with a water supply pipe, said case having a first cavity and a second cavity in an interior of said case, the first cavity communicating with the first water outlets, the second cavity communicating with the second end of said case;
• a pressing structure positioned at the first end of said case, said pressing structure comprising a lock nut, a pressing component and a positioning component, the lock nut pressing on the pressing component, the positioning component positioning the pressing component, the pressing component having a first spring sleeved thereon, the first spring urging the pressing component toward the lock nut;
• a stem seat positioned in an interior of said case;
• a valve stem pivotally mounted to said stem seat;
• an inner casing positioned in the interior of said case, said inner casing having one end connected to the positioning component, another end of said inner casing being connected to a liner bushing, said inner casing having a pair of sides each having a second water outlet, the second water outlets respectively communicating with the first water outlets, the first cavity and the second cavity being formed within said inner casing, the first cavity communicating with the second water outlets;
• and
• a separator positioned in an internal portion of said inner casing, said separator positioned between the first cavity and a second cavity, said separator having an intercommunicating pore through which the first cavity and a second cavity communicate with each other, wherein said stem seat is positioned on an annular inner edge of the liner bushing, the stem seat being located between the second end of said case and the second cavity, said stem seat having a plurality of channels, each channel of the plurality of channels respectively communicating with the second end of the case and the second cavity, wherein said valve stem is positioned inside the second cavity, said valve stem being in face-to-face relationship with the pressing component such that the pressing component urges said valve stem toward the second end of said case, said valve stem having one end formed with a cap end, said valve stem having another end pivotally mounted to said stem seat, wherein the cap end has a seal sheathed thereto, an outer diameter of the seal being larger than an inner diameter of the intercommunicating pore such that the seal can block communication between the intercommunicating pore and the second cavity, said valve stem being sleeved with a second spring extending between the cap end and said stem seat, the second spring having one end urging against said stem seat and another end urging against the cap end such that said valve stem moves toward said separator, said valve stem having peripheral radiating sides with a plurality of supporting wings, an outer end of each of the plurality of supporting wings respectively urging against a peripheral wall of the second cavity.
