The invention discloses a switching valve core. The switching valve core comprises a switching body; a shell is disposed in the switching body and comprises an upper shell body and a lower shell body;a core shaft is disposed in the shell and provided with a plurality of grooves; the grooves comprise left protruding blocks and right protruding blocks; the diameter of the left protruding blocks isequal to that of the right protruding blocks; seal rings are disposed in the grooves; one end of the core shaft is covered with the lower shell body, and the other end of the core shaft is covered with the upper shell body; a reset spring is arranged between the core shaft and the lower shell body; a rotating part is connected to the other end of the core shaft; first elastic teeth are disposed onthe rotating part; a built-in button is matched and connected with the rotating part; second elastic teeth which act by cooperating with the first elastic teeth are disposed on the built-in button; and a step surface which is used for making contact with and being matched with the first elastic teeth is disposed in the upper shell body. By means of the switching valve core, the problem that a water channel cannot be switched normally under high pressure is solved, and the experience feeling of users is improved.
