the rotor valve core is attached to the valve head,

the valve head is provided with at least three reversing connectors, the rotor valve core is provided with a groove, and

the groove is in communication with the reversing connector; and

the first drive assembly is configured to drive the valve core seat to rotate, and the second drive assembly is configured to drive the rotor valve core to slide.

2. The fluid cross-free switching valve of claim 1 , wherein

the valve core seat is provided with a chute,

the rotor valve core is slidably connected to the chute,

an end surface, away from the valve head, of the rotor valve core is provided with a guide groove,

a length direction of the guide groove is perpendicular to a length direction of the chute, and

the valve body further comprises an eccentric shaft, wherein the eccentric shaft is rotatably inserted into the valve core seat, and an end of the eccentric shaft is movably accommodated in the guide groove.

3. The fluid cross-free switching valve of claim 2 , wherein the eccentric shaft comprises a drive shaft and a connecting strut, wherein

the connecting strut protrudes at an end portion of the drive shaft,

a central axis of the connecting strut is staggered from a central axis of the drive shaft,

a bearing is mounted on the connecting strut, and the bearing is accommodated in the guide groove.

4. The fluid cross-free switching valve of claim 2 , wherein

the length direction of the chute is arranged along a radial direction of the valve core seat,

a length direction of the groove is parallel to the length direction of the chute, and

the groove is arranged along the radial direction of the valve core seat.

5. The fluid cross-free switching valve of claim 2 , wherein the valve body further comprises a rotor wear-resistant member, wherein

the rotor wear-resistant member is matched with the chute,

the rotor wear-resistant member is mounted in the chute, and

the rotor valve core is attached to the rotor wear-resistant member.

6. The fluid cross-free switching valve of claim 2 , wherein the valve body further comprises a valve seat, wherein

the valve head is mounted on a first end of the valve seat,

the valve seat is sleeved outside the valve core seat, and

the valve core seat is rotatable relative to the valve seat.

7. The fluid cross-free switching valve of claim 6 , wherein the valve body further comprises a plane bearing and an elastic member, wherein

a contact surface is formed on the valve core seat,

the plane bearing is sleeved outside the valve core seat,

the elastic member is telescopically arranged between the plane bearing and the contact surface, and

an end surface of the plane bearing contacts an inner wall of a second end of the valve seat.

8. The fluid cross-free switching valve of claim 2 , wherein the rotary valve further comprises a housing, wherein the valve body is mounted on an end of the housing, and both the first drive assembly and the second drive assembly are mounted in the housing.

9. The fluid cross-free switching valve of claim 8 , wherein

the first drive assembly comprises a first drive motor and a first deceleration mechanism, wherein

the first drive motor is connected to a power input end of the first deceleration mechanism, and

a power output end of the first deceleration mechanism is connected to the valve core seat; and

the second drive assembly comprises a second drive motor and a second deceleration mechanism, wherein

the second drive motor is connected to a power output end of the second deceleration mechanism, and

the power output end of the second deceleration mechanism is connected to the eccentric shaft after rotatably passing through the first drive assembly.

10. The fluid cross-free switching valve of claim 1 , wherein

the at least three reversing connectors are evenly distributed along a circumference of the valve head,

a center of the valve head is provided with a common connector for inflowing fluid along an axial direction of the valve head, and

the common connector is in communication with the groove.
