DETAILED DESCRIPTION

[0030] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0031] The present invention provides the following preferred embodiments:

[0032] Example 1, as Figures 1-8 As shown, a single-handle single-hole pull-out basin faucet water-saving valve core includes a housing 11, a first blocking plate 12, a second blocking plate 13, an adjusting plate 14 and a water outlet mechanism. The first blocking plate 12 is fixedly mounted on the bottom end of the housing 11, the second blocking plate 13 is located above the first blocking plate 12 and fixed to the inner wall of the housing 11, the adjusting plate 14 is located between the first blocking plate 12 and the second blocking plate 13, and the adjusting plate 142 is rotatably arranged inside the housing 11;

[0033] The water outlet mechanism includes a water outlet 16, two water inlets 15, a first water hole 20, a second water hole 21, an adjustment assembly and a positioning assembly. The two water inlets 15 are installed on the end of the first blocking plate 12 away from the adjustment plate 14. The water outlet 16 is fixed to the side of the adjustment plate 14 close to the first blocking plate 12. The water outlet 16 is arranged through the first blocking plate 12. The first water hole 20 and the second water hole 21 are both opened on the surface of the adjustment plate 14. The adjustment assembly is installed between the adjustment plate 14 and the housing 11. The positioning assembly is located between the second blocking plate 13 and the adjustment assembly. Specifically, the two water inlets 15 are respectively connected to the cold water pipe and the hot water pipe;

[0034] By means of the first water hole 20 and the second water hole 21 having different widths, when the first water hole 20 is connected to the water inlet 15, the water flow rate of the water outlet 16 is large, and when the second water hole 21 is connected to the water inlet 15, the water flow rate of the water outlet 16 is small. Thus, by adjusting the positions of the first water hole 20 and the second water hole 21, the water flow rate of the water outlet 16 can be adjusted, thereby avoiding the situation where a large water flow rate causes a waste of water resources, thereby achieving a water-saving effect and being able to meet different water flow requirements.

[0035] When the first water hole 20 or the second water hole 21 is connected to one or both water inlets 15, water in the water inlet 15 flows through the first water hole 20 or the second water hole 21 into the space between the regulating plate 14 and the second blocking plate 13, and then flows through the water outlet 16 to the faucet.

[0036] When the first water hole 20 or the second water hole 21 is connected to one of the water inlets 15, a water outlet mode of one temperature can be achieved. When the first water hole 20 or the second water hole 21 is connected to the other water inlet 15, another water outlet mode of another temperature can be achieved, thereby making the valve core have a specific hot and cold water adjustment function and more flexible to use.

[0037] like Figures 1-8 As shown, the adjustment mechanism includes a rotating plate 22, a rotating member, and multiple rotating plates 22 located between the second blocking plate 13 and the adjustment plate 14. Multiple fixing rods 23 are equidistantly fixed to the outside of the rotating plate 22. The other end of each fixing rod 23 is fixedly connected to the adjustment plate 14. The rotating member is located between the rotating plate 22 and the housing 11.

[0038] A channel for water flow is formed between two adjacent fixing rods 23, so that water flow can enter the interior of the water outlet 16;

[0039] The rotating member can drive the rotating plate 22 to rotate, and when the rotating plate 22 rotates, the adjusting plate 14 can be driven to rotate inside the shell 11, so that the first water hole 20 and the second water hole 21 on the adjusting plate 14 can be rotated, thereby adjusting the position of the first water hole 20 and the second water hole 21, making it convenient for the first water hole 20 or the second water hole 21 to connect with the water inlet 15.

[0040] like Figures 1-8 As shown, the rotating member includes a rotating shaft 24, a first bevel gear 25, a second bevel gear 26 and a rotating rod 27. The rotating shaft 24 is rotatably arranged on the second blocking plate 13 through a bearing. One end of the rotating shaft 24 is fixedly connected to the rotating plate 22. The first bevel gear 25 is located above the second blocking plate 13 and is fixedly mounted on the surface of the rotating shaft 24. The rotating rod 27 is rotatably arranged on the housing 11 through a bearing. The second bevel gear 26 is fixedly mounted on one end of the rotating rod 27. The second bevel gear 26 and the first bevel gear 25 are meshed with each other.

[0041] Specifically, the other end of the rotating rod 27 can be connected to the knob of the faucet, and the rotating rod 27 is driven to rotate by the knob, and the rotating rod 27 drives the second bevel gear 26 to rotate. Since the second bevel gear 26 and the first bevel gear 25 are engaged with each other, the second bevel gear 26 can drive the first bevel gear 25 to rotate when it rotates, thereby driving the adjustment plate 14 to rotate through the rotating shaft 24 and the rotating plate 22 to realize the opening and closing of the water flow.

[0042] like Figures 1-8 As shown, the width of the first water hole 20 is greater than the width of the second water hole 21 .

[0043] like Figures 1-8 As shown, the positioning assembly includes a mounting frame 33, a ball 29, a positioning groove 28 and a telescopic assembly. The mounting frame 33 is fixedly mounted on one side of the top of the rotating plate 22, the ball 29 is located above the mounting frame 33, and the telescopic assembly is located between the ball 29 and the mounting frame 33. The bottom surface of the second blocking plate 13 is provided with a positioning groove 28 that cooperates with the ball 29.

[0044] When the ball 29 is engaged with the inside of the positioning groove 28, the first water hole 20 and the second water hole 21 are not connected to the water inlet 15, and the faucet can be closed, which is convenient for positioning the closed state of the faucet and can prevent accidental contact.

[0045] like Figures 1-8 As shown, the telescopic assembly includes a slide rod 30, a sleeve 31 and a spring 32. The sleeve 31 is fixedly mounted on a mounting bracket 33. The bottom end of the slide rod 30 is slidably arranged inside the sleeve 31. The top end of the slide rod 30 is provided with a mounting groove that matches the ball 29. The ball 29 is mounted inside the mounting groove. The spring 32 is located inside the sleeve 31. The two ends of the spring 32 are respectively connected to the slide rod 30 and the sleeve 31.

[0046] In the initial state, the ball 29 is engaged with the interior of the positioning groove 28, and the spring 32 is in a compressed but not fully compressed state;

[0047] When the rotating plate 22 rotates, it can drive the mounting bracket 33 to rotate. At this time, the ball 29 rotates synchronously with the mounting bracket 33, and the ball 29 moves out from the inside of the positioning groove 28. The spring 32 is further compressed, and the positioning of the rotating plate 22 is also released.

[0048] like Figures 1-8As shown, an arc-shaped rod 34 is provided under the second blocking plate 13, and mounting plates 35 are fixed at both ends of the arc-shaped rod 34. Each mounting plate 35 is mounted on the second blocking plate 13, and a surface sliding sleeve of the arc-shaped rod 34 is provided with an arc-shaped sleeve 36. The arc-shaped sleeve 36 is fixedly mounted on one side of the mounting bracket 33. When the rotating plate 22 rotates, the arc-shaped sleeve 36 can be driven by the mounting bracket 33 to slide on the arc-shaped rod 34, playing a guiding role. At the same time, it can also limit the mounting bracket 33 to prevent the rotating plate 22 from rotating at an excessive angle.

[0049] like Figures 1-8 As shown, a guide rail 18 is fixed to the inner wall of the housing 11, and a circular ring 19 is provided inside the guide rail 18 for rotation. The circular ring 19 is fixedly mounted on the top of the adjustment plate 14. The guide rail 18 and the circular ring 19 can support and guide the adjustment plate 14. Specifically, a bearing is provided between the guide rail 18 and the circular ring 19.

[0050] like Figures 1-8 As shown, a through hole 17 is provided in the middle of the first blocking plate 12 for the water outlet 16 to pass through, and the inner walls of the water outlet 16 and the two water inlets 15 are provided with internal threads 41. The setting of the internal threads 41 is conducive to connecting the valve core with an external pipeline.

[0051] like Figures 1-8 As shown, two second grooves 40 are provided on the inner wall of the perforation 17, and two second sealing rings 38 are installed on the outer wall of the water outlet 16. Each second sealing ring 38 is clamped in the inside of a second groove 40. The second sealing ring 38 can increase the sealing effect between the water outlet 16 and the water inlet 15. The top surface of the first sealing plate 12 is provided with a first groove 39, and the bottom end of the adjusting plate 14 is fixed with a first sealing ring 37. The first sealing ring 37 is clamped in the inside of the first groove 39. The first sealing ring 37 can increase the sealing effect between the adjusting plate 14 and the first sealing plate 12, thereby making the sealing effect of the valve core better.

[0052] The beneficial effects of the present invention are specifically embodied in that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
