a fixed valve plate mounted on the base in a liquid tight mode, which is unable to rotate relative to the base; the fixed valve plate comprises:

a first water-inlet channel axially formed at the central portion of the fixed valve plate; the first water-inlet channel of the fixed valve plate and the first water-inlet channel of the base communicate with each other;

at least one second water-inlet channel axially formed on the fixed valve plate; the at least one second water-inlet channel of the fixed valve plate and the at least one second water-inlet channel of the base communicate with each other; and

at least one water outlet channel axially formed on the fixed valve plate; the water outlet channel of the fixed valve plate and the water outlet channel of the base plate communicate with each other; and

a movable valve plate which is rotationally arranged on the fixed valve plate in a liquid tight mode; the movable valve plate comprises:

a communicating groove which is formed on a surface of the movable valve plate that is attached to the fixed valve plate; one end of the communicating groove and the first water-inlet channel of the fixed valve plate communicate with each other, and the second end of the communicating groove selectively communicates with the water outlet channel on the fixed valve plate; and

a groove which is formed on the side edge of the movable valve plate and selectively corresponds to at least one second water-inlet channel of the fixed valve plate; and

a manipulation assembly which is configured on the movable valve plate to manipulate the movable valve plate to rotate relative to the fixed valve plate; the manipulation assembly comprises:

a disc body which is configured and clamped to the movable valve plate opposite to the other surface of the fixed valve plate; the disc plate is formed with a communicating groove and the communicating groove of the disc plate and the groove of the movable valve plate communicate with each other; and

a control rod which is concentrically mounted on the disc body and extended to penetrate the through end of the housing, and close the through end of the housing in a liquid tight mode; the control rod is axially formed with a through hole, and the through hole communicates with the communicating grooves of the disc body.

2. The valve core defined in claim 1 , wherein two second water-inlet channels are axially formed on the base; the fixed valve plate is axially formed with two second water-inlet channels; each second water-inlet channel on the fixed valve plate communicates with a corresponding second water-inlet channel on the base; the water outlet channel of the base is disposed in an arc shape, and both ends of the water outlet channel are respectively extended toward the direction of a corresponding second water-inlet channel on the base; the fixed valve plate is formed with two water outlet channels; each water outlet channel of the fixed valve plate communicates with the water outlet channel on the base.

3. The valve core defined in claim 2 , wherein the communicating groove on the movable valve plate is radially disposed; when the movable valve plate reciprocally rotates relative to the fixed valve plate, the second end of the communicating groove selectively communicates with a corresponding water outlet channel on the fixed valve plate, and the groove selectively communicates with a corresponding second water-inlet channel on the fixed valve plate.

4. The valve core defined in claim 3 , wherein the end face of the movable valve plate attached to the fixed valve plate is divided into four quadrants by the mutually orthogonal X-axis and Y-axis; the two water outlet channels of the fixed valve plate are respectively located in the first quadrant and the second quadrant, and the two second water-inlet channels of the fixed valve plate are respectively located in the third quadrant and the fourth quadrant, wherein the water outlet channels on the first quadrant corresponds to the second water-inlet channels on the third quadrant in usage, and the water outlet channels on the second quadrant corresponds to the second water-inlet channels on the fourth quadrant in usage; for the fixed valve plate, the second water-inlet channels on the third and fourth quadrants respectively communicate with the first water outlet and the second water outlet of the water purification device through a corresponding second water-inlet channel of the base.

5. The valve core defined in claim 4 , wherein the disc body is formed with a slot on each of the two sides of the communicating slot opposite to the other surface of the movable valve plate, and the control rod is extended with two tenons with respect to the end of the disc body; When the control rod is concentrically mounted and clamped on the disk body, each tenon is inserted into a corresponding slot.

6. The valve core defined in claim 2 , wherein the end face of the movable valve plate attached to the fixed valve plate is divided into four quadrants by the mutually orthogonal X-axis and Y-axis; the two water outlet channels of the fixed valve plate are respectively located in the first quadrant and the second quadrant, and the two second water-inlet channels of the fixed valve plate are respectively located in the third quadrant and the fourth quadrant, wherein the water outlet channels on the first quadrant corresponds to the second water-inlet channels on the third quadrant in usage, and the water outlet channels on the second quadrant corresponds to the second water-inlet channels on the fourth quadrant in usage; for the fixed valve plate, the second water-inlet channels on the third and fourth quadrants respectively communicate with the first water outlet and the second water outlet of the water purification device through a corresponding second water-inlet channel of the base.

7. The valve core defined in claim 6 , wherein the disc body is formed with a slot on each of the two sides of the communicating slot opposite to the other surface of the movable valve plate, and the control rod is extended with two tenons with respect to the end of the disc body; When the control rod is concentrically mounted and clamped on the disk body, each tenon is inserted into a corresponding slot.
