a valve cartridge of a cylindrical shape, the valve cartridge being disposed in the valve seat in a close engagement manner with the valve seat, and a plurality of communication grooves being defined on a circumferential surface of the valve cartridge and arranged in a second predetermined pattern; and
a driving assembly in transmission connection with the valve cartridge, the driving assembly being configured to drive the valve cartridge to rotate by a predetermined angle to bring at least one target communication groove of the plurality of communication grooves into communication with a plurality of target openings of the N openings respectively, to allow for communication between the channel interfaces corresponding to the plurality of the target openings,
wherein each of the at least one target communication groove is in communication with at least two of the plurality of target openings,
wherein N is equal to 9,
wherein nine channel interfaces are arranged in three rows, four of the nine channel interfaces being arranged on an upper row of the three rows, four of the nine channel interfaces being arranged on a lower row of the three rows, and one of the nine channel interfaces being arranged on a middle row of the three rows; and
wherein the plurality of communication grooves defined on the circumferential surface of the valve cartridge is arranged in two rows comprising an upper row and a lower row or arranged in three rows, the plurality of communication grooves comprising:
a first communication groove configured to communicate the four channel interfaces on the upper row of the channel interfaces with the one channel interface on the middle row of the channel interfaces;
a second communication groove configured to communicate the four channel interfaces on the lower row of the channel interfaces with the one channel interface on the middle row of the channel interfaces; and
a third communication groove configured to communicate the four channel interfaces on the upper row of the channel interfaces with the four channel interfaces on the lower row of the channel interfaces.

2. The integrated multi-way valve according to claim 1 , wherein:
a rotary shaft is provided for the valve cartridge and located on a central axis of the valve cartridge; and
the driving assembly comprises:
