The valve cartridge of claim 8, wherein: the second water outlet is arranged in the middle of the first water dividing sheet, and the second hot water inlet and the second cold water inlet are arranged on two sides of the second water outlet and are arranged at intervals along the circumferential direction of the first water dividing sheet.

10. The valve cartridge of claim 1, wherein: the valve core further comprises a limiting device, the limiting device is configured to limit the second water dividing sheet to slide relative to the first water dividing sheet when the second water dividing sheet is in the first switching state, and the limiting device is further configured to limit the rotating range of the second water dividing sheet when the second water dividing sheet is in the second switching state.

11. The valve cartridge of claim 10, wherein: the limiting device comprises a connecting block which moves synchronously with the second water diversion piece, and also comprises a first limiting groove and a limiting convex wall which sequentially extend along the circumferential direction of the second water diversion piece;

when the initial state is changed into the first switching state, the first end of the connecting block is changed from the corresponding first limiting groove to the corresponding limiting convex wall to limit the sliding of the connecting block;

when the initial state is changed to the second switching state, the first end of the connecting block correspondingly and slidably extends into the first limiting groove, and the first end of the connecting block is slidably abutted against two end faces of the first limiting groove arranged along the circumferential direction.

12. The valve cartridge of claim 11, wherein: the limiting device also comprises a first limiting groove, a limiting convex wall and a second limiting groove which sequentially extend along the circumferential direction of the second water diversion piece;

in an initial state, the second end of the connecting block extends into the second limiting groove to be limited by two end faces of the second limiting groove arranged along the circumferential direction and rotate in a first rotating range;

when the first switching state is carried out, the first end of the connecting block correspondingly props against the limiting convex wall, and the second end correspondingly props against the bottom wall of the second limiting groove so as to limit the sliding of the connecting block.

13. A water outlet device is characterized in that: use is made of a valve cartridge according to any one of claims 1 to 12.
