In the above structure, the existing stator 13 is provided with a first pure water port 134 and one or two second pure water ports 135, and the pure water tank 142 on the rotor 14 is matched; when the handle 11 is in the closed state, that is, the handle 11 is not swung and the rotation range of the handle 11 is located at the central position, the first purified water port 134 and the second purified water port 135 are blocked by the movable plate 14, the first purified water port 134 is in the closed state, on the basis, the handle 11 is rotated, the purified water tank 142 can rotate along with the movable plate 14, the purified water tank 142 is rotated to be positioned between the first purified water port 134 and the second purified water port 135, the purified water enters the purified water tank 142 from the second purified water port 135 and then flows out from the first purified water port 141 (the purified water is switched in and out, or the purified water enters the purified water tank 142 from the first purified water port 134 and then flows out from the second purified water port 135), the control of the purified water is realized, when the second purified water ports 135 are two, the clockwise rotation or the counterclockwise rotation of the handle 11 can enable the movable plate 14 to drive the purified water tank 142, so that the purified water tank 142 is rotated to be positioned between the first purified water port 134 and any one of the second purified water ports 135, therefore, the handle 11 is ensured to rotate clockwise and anticlockwise to control pure water outlet, when the pure water needs to be closed, the handle 11 only needs to be rotated to the central position of the rotation range of the handle 11 (it is noted that when the handle 11 is not swung and is in a closed state, and only the handle 11 is rotated, the mixed water outlet 133 and the mixed water tank 141 are always concentric); when mixed water needs to be discharged, the handle 11 is swung, that is, the handle 11 swings, and the rotation range of the handle 11 is located at the central position, the water mixing tank 141 slides along the radial direction of the rotation direction of the handle 11 (or understood as the housing 10) along with the movable piece 14, so that the water mixing tank 141 is communicated with the cold water inlet 131 and the hot water inlet 132, at the moment, cold water and hot water enter the water mixing tank 141 together and are discharged from the water mixing outlet 133, and discharge of warm water is realized, and on the basis, the handle 11 is rotated, so that the water mixing tank 141 can rotate along with the movable piece 14, and therefore, flow cross section changes among the cold water inlet 131, the hot water inlet 132 and the water mixing tank 141 are controlled, and cold and hot adjustment or pure cold water discharge or pure hot water discharge is realized; in the water mixing mode, the swing of the handle 11 of the movable plate 14 reduces the turning radius of the pure water tank 142, so that the movable plate is always staggered with the first pure water port 134 and the second pure water port 135 when the handle 11 swings to the water mixing mode and rotates, the opening and closing of the pure water is independently controlled by the rotation before the handle 11 swings, the water outlet of the mixed water is independently controlled after the handle 11 swings, the cold and hot regulation of the mixed water is independently controlled, the vacancy of the left and right rotation when the handle 11 of the existing cold and hot water valve core is in the closed position is skillfully utilized, and the water outlet control of the pure water is realized; meanwhile, when the handle 11 is in a swinging opening state and rotates to adjust the mixing ratio of cold water and hot water, the cold water and the hot water can be swung at any rotating position to reset and close or the pure water can be opened while the cold water and the hot water are closed, and the device has the advantages of simple structure, convenience in operation and no influence on the execution of industrial standards.

In this embodiment, the mixed water outlet 133 is disposed in the center of the fixed blade 13; the cold water inlet 131 and the hot water inlet 132 are respectively positioned at the left side and the right side below the mixed water outlet 133; the first pure water port 134 is located above the mixed water outlet 133, the second pure water port 135 is located on the left side or right side or left and right sides of the first pure water port 134, and the first pure water port 134 and the second pure water port 135 are arranged at intervals in the circumferential direction of the stator 13; the virtual turning radius r1 generated by the first pure water port 134 and the second pure water port 135 with the mixed water outlet 133 as the turning center is larger than the virtual turning radius r2 generated by the cold water inlet 131 and the hot water inlet 132 with the mixed water outlet 133 as the turning center, and the radius difference between the two is larger than or equal to the distance of the driving moving plate 14 sliding along the radial direction of the shell 10 when the handle 11 swings; the distance L1 from the pure water tank 142 to the water mixing tank 141 is the same as the virtual radius of gyration r1 between the first pure water port 134, the second pure water port 135 and the water mixing outlet 133.

In the above structure, reference to the clock dial can be understood as: the mixed water outlet 133 is positioned at the rotation axis of the clock pointer, the cold water inlet 131 and the hot water inlet 32 are respectively positioned at the 3 o ' clock position to the 6 o ' clock position and the 6 o ' clock position to the 9 o ' clock position, the first purified water port 134 is positioned at the 12 o ' clock position, and the second purified water port 135 is positioned at the 1 o ' clock position to the 2 o ' clock position or/and the 10 o ' clock position to the 11 o ' clock position; the radiuses r1 of the first and second pure water ports 134 and 135 from the rotation axis of the handle 11 (or understood as the central axis of the housing 10 or the center of the stationary blade 13) are equal to each other and larger than the radiuses of the cold water inlet 131, the hot water inlet 132 to the rotation axis of the handle 11 (or understood as the central axis of the housing 10 or the center of the stationary blade 13), and the difference between the radiuses is used for sealing and shielding the pure water tank 142 by the stationary blade 13 at the 9 o 'clock to 3 o' clock position when the handle 11 swings and rotates, so as to prevent the pure water tank 142 from draining water.

In this embodiment, the mixed water outlet 133 faces one end of the moving plate 14, and an inner wall of an orifice on a side of the mixed water outlet 133 close to the first pure water port 134 is offset toward the center of the mixed water outlet 133, so that the orifice is in a "D" shape; the first pure water gap 134 is provided with a pure water feeding slot 1341 extending in the circumferential direction of the fixed plate 13 as a reference, wherein the extending arc length 1 of the pure water feeding slot 1341 is smaller than the arc length 2 of the first pure water gap 134 to the second pure water gap 135 with reference to the circumferential direction of the fixed plate 13 or the arc length 3 of the first pure water gap 135 with reference to the circumferential direction of the fixed plate 13.
