1. A multi-way valve, comprising a valve seat, a first valve core, a second valve core, and a driving device; wherein
the driving device is drivingly connected to the first valve core;
the first valve core is provided with a first matching structure, and the second valve core is provided with a second matching structure that matches with the first matching structure, the first matching structure and the second matching structure have a first matching state and a second matching state, and in the first matching state, the first valve core rotates alone, and the second valve core remains stationary, and in the second matching state, the first valve core rotates to drive the second valve core to rotate synchronously;
the valve seat is provided with a plurality of first valve ports corresponding to the first valve core, and the first valve core is provided with a first communication structure, and the first communication structure is configured to make at least two first valve ports communicate with each other when the first valve core rotates to a first predetermined position;
the valve seat is provided with a plurality of second valve ports corresponding to the second valve core, and the second valve core is provided with a second communication structure, and the second communication structure is configured to make at least two second valve ports communicate with each other when the second valve core rotates to a second predetermined position;
wherein the first matching structure comprises a protrusion structure disposed on a first end surface of the first valve core, and the second matching structure comprises a groove structure disposed on a second end surface of the second valve core, the first end surface is opposite to the second end surface, and at least a portion of the protrusion structure is located in the groove structure;
an inner peripheral surface of the groove structure is provided with a first protrusion part, and the first protrusion part comprises a first end surface and a second end surface which are arranged at intervals in a circumferential direction of the inner peripheral surface of the groove structure, and in the first matching state, the protrusion structure is not in contact with the first end surface and the second end surface, and in the second matching state, the protrusion structure abuts against the first end surface or the second end surface;
wherein the inner peripheral surface of the groove structure comprises a first cylindrical surface, and the first protrusion part is disposed on the first cylindrical surface;
the protrusion structure comprises a first cylinder body, and a second protrusion part protruding radially outward from an outer peripheral surface of the first cylinder body; the outer peripheral surface of the first cylinder body is located at a radial inside of the first protrusion part of the first protrusion part, two end surfaces of the second protrusion part in a circumferential direction of the second protrusion part respectively form a first side surface and a second side surface;
an outer peripheral surface of the second protrusion part comprises a second cylindrical surface, and the second cylindrical surface is adapted to the first cylindrical surface.
