The utility model with the publication number CN2499645Y provides a water-saving faucet ceramic valve core for adjusting the water flow in stages, which is composed of a lever, a bracket, a valve body, a dial, a movable valve plate, a spring, a steel ball, etc. The characteristic is that there is an extended step on one side of the upper end face of the bracket, and there is an arc groove on the side where the step contacts the lever. There is a through hole on the lever, and its position corresponds to the position of the groove. The through hole is equipped with a steel ball, a spring, and a screw.

When the movable plate 3 is in the first position, the water sealing area 301 blocks the cold water inlet 201 and the hot water inlet 202 to close the temperature control valve core; when the movable plate 3 is in the second position, the first through hole 302 is connected with the cold water inlet 201 and the hot water inlet 202, and the second through hole 303 is connected with the first water outlet through hole 203 to achieve a first gear of water outlet; when the movable plate 3 is in the third position, the first through hole 302 is connected with the cold water inlet 201 and the hot water inlet 202, and the second through hole 303 is connected with the first water outlet through hole 203 and the second water outlet through hole 205 at the same time to achieve a second gear of water outlet.

[0029] Combination Figures 1 to 3As shown, in this embodiment, the valve core includes a housing, and the housing includes an upper housing 1 and a base 4, and the static plate 2 can be fixed on the base 4. A sealing cover 5 is arranged above the moving plate 3, and a sealing ring 6 is arranged between the sealing cover 5 and the moving plate 3 to form a water mixing chamber 304 in the moving plate 3; a rotating seat 7 is arranged above the sealing cover 5, and a lever 8 is hinged in the rotating seat 7, and the lever 8 is hinged in the rotating seat 7 through a rotating shaft 9, so that the sealing cover 5 and the moving plate 3 can be driven to rotate and / or slide on the static plate 2 at the same time during the swinging process to achieve water outlet control. In order to achieve the grading effect, a spring member 10 and a marble 11 are also arranged on the lever 8, and a grading structure cooperating with the marble 11 is arranged on the rotating seat 7, so that when the lever 8 is rotated to different positions, precise grading can be achieved through the cooperation of the marble 11 and the grading structure. There can be many types of grading structures here, and the principle is the existing technology, which will not be elaborated here.

[0030] In this embodiment, the moving piece 3 and the static piece 2 can be made of ceramic or other suitable materials.

[0031] Combination Figure 7 As shown, the static sheet 2 can be set in a circular shape, which is fixedly connected to the base 4, so as to fix the static sheet 2 in the shell to prevent the static sheet 2 from rotating. The static sheet 2 includes a cold water inlet 201, a hot water inlet 202, a first water outlet through hole 203 and a second water outlet through hole 205. In this embodiment, the cold water inlet 201, the hot water inlet 202 and the second water outlet through hole 205 form a circle; the first water outlet through hole 203 is arranged between the second water outlet through hole 205 and the cold water inlet 201 and the hot water inlet 202, that is, the first water outlet through hole 203 is arranged in the middle position. Specifically, the cold water inlet 201 and the hot water inlet 202 can be symmetrically arranged along the diameter direction of the static plate 2; the second water outlet through hole 205 is arranged in an arc shape, and the first water outlet through hole 203 can be arranged on the symmetrical line of the second water outlet through hole 205 and the cold water inlet 201 and the hot water inlet 202, and is located in the middle of the second water inlet through hole and the cold water inlet 201 and the hot water inlet 202. In this embodiment, the first water outlet through hole 203 and the second water outlet through hole 205, the cold water inlet 201, and the hot water inlet 202 can all be connected at the bottom of the valve core to achieve the effect of bottom in and bottom out.

[0032] Combination Figures 8 to 9As shown, the moving plate 3 includes a water sealing area 301, a first through hole 302 and a second through hole 303, wherein the first through hole 302 and the second through hole 303 can be arranged at two halves of the moving plate 3 opposite to each other, and the first through hole 302 and the second through hole 303 can form the water sealing area 301. The first through hole 302 is suitable for connecting with the cold water inlet 201 and the hot water inlet 202, and when the moving plate 3 rotates, the water inlet ratio of the first through hole 302 and the cold water inlet 201 and the hot water inlet 202 will change accordingly, thereby changing the ratio of cold water to hot water entering the water mixing chamber 304, thereby achieving a temperature adjustment effect. The second through hole 303 is always connected with the second water outlet through hole 205. When the movable plate 3 slides on the static plate 2, when it is in the first position, the water sealing area 301 blocks the cold water inlet 201 and the hot water inlet 202 to close the thermostatic valve core; when the movable plate 3 moves to the second position driven by the user, the first through hole 302 is connected with the cold water inlet 201 and the hot water inlet 202, and the second through hole 303 is connected with the second water outlet through hole 205, and at this time, a small amount of water is discharged (for example, when the lever is in a vertical state); when the movable plate 3 moves to the third position, the first through hole 302 is connected with the cold water inlet 201 and the hot water inlet 202, and the second through hole 303 is connected with the first water outlet through hole 203 and the second water outlet through hole 205 at the same time, and at this time, water is discharged from the two water outlet through holes at the same time, and the water output is greater than the water output at the second position. In this embodiment, three gears are set, namely, closed, first-gear water outlet, and second-gear water outlet. However, in other embodiments, the ratio of the openings of the second through hole 303 to the first water outlet through hole 203 and the second water outlet through hole 205 can be controlled as needed, thereby controlling the ratio of the water outlet to achieve a multi-gear adjustment effect. Therefore, more gears can be set as needed. During the gear adjustment process, the moving piece 3 can be rotated synchronously to adjust the temperature, thereby achieving the effect of achieving temperature adjustment and grading at the same time.

[0033] Continue to combine Figures 7 to 9 As shown, in this embodiment, the second through hole 303 is arranged at the edge of the water mixing chamber 304, and the through hole height of the second through hole 303 at the edge of the water mixing chamber 304 is higher than the bottom surface of the water mixing chamber 304 so that the second through hole 303 and the second water outlet through hole 205 are kept in communication. In addition, an extension groove 204 is arranged on the side where the first water outlet through hole 203 is connected to the moving plate 3 so that the second through hole 303 can simultaneously connect the first water outlet through hole 203 and the second water outlet through hole 205. Through the arrangement of the extension groove 204, the moving plate 3 can complete the adjustment of the water volume by moving a small part of the displacement, which is convenient for control. In addition, the second through hole 303 does not need to be arranged very large, which is conducive to the miniaturization design of the entire valve core.

[0034] In this embodiment, the water path structure of the movable plate 3 and the static plate 2 is set so that the valve core can simultaneously perform temperature adjustment and water volume adjustment in stages. The movable plate 3 is controlled to slide on the static plate 2 to connect the second through hole 303 to the second water outlet through hole 205 or to connect the first water outlet through hole 203 and the second water outlet through hole 205 at the same time, so as to control the water outlet volume. The user can adjust the water outlet gear and the water outlet temperature according to needs. In addition, the scheme of this embodiment can realize rapid switching of water volume in a smaller space. The water path design is simpler and more sophisticated, which is conducive to the miniaturization of the valve core design while maintaining a large water outflow.
