[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] It should be noted that in the description of this application, the terms "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," which indicate directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. These terms are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] Example 1, as Figures 1-10 As shown, one embodiment of this application provides a water servo mechanism, including: Valve housing 1, wherein the valve housing 1 is provided with an inlet 11, a first outlet 12 and a second outlet 13; The first adjusting component 2 has a cylindrical structure, and the side wall of the first adjusting component 2 is provided with a first through hole 21 and a second through hole 22. The second adjusting component 3 has a water inlet 31 at one end, and the side wall of the first adjusting component 2 has a third through hole 32 and a fourth through hole 33. The water inlet 31 is connected to the third through hole 32 and the fourth through hole 33. Drive component 4; The first adjusting component 2 is sleeved outside the second adjusting component 3. The first adjusting component 2 is rotatably disposed in the valve housing 1, and the second adjusting component 3 is disposed inside the valve housing 1. The water inlet 31 is connected to the water inlet 11. The third through hole 32 is arranged opposite to the first water outlet 12, and the fourth through hole 33 is arranged opposite to the second water outlet 13. In addition, the driving component 4 is disposed on the valve housing 1 and configured to drive the first adjusting component 2 to rotate within the valve housing 1, so as to adjust the overlapping area formed between the first through hole 21 and the third through hole 32 and the overlapping area formed between the second through hole 22 and the fourth through hole 33.

[0026] Specifically, the valve housing 1 of the water servo mechanism is provided with a water inlet 11 to introduce water flow into the valve housing 1. The water flow into the valve housing 1 enters the cavity formed inside the second regulating component 3 through the water inlet 31 of the second regulating component 3. The water flowing into the second regulating component 3 can flow out from the third through hole 32 and / or the fourth through hole 33 as needed. At the same time, the water flowing out from the second regulating component 3 will flow out through the first through hole 21 and / or the second through hole 22 as needed and finally be output through the first outlet 12 and the second outlet 13.

[0027] During the adjustment process, the driving component 4 drives the first adjusting component 2 to rotate on the second adjusting component 3, thereby adjusting the opening area of ​​the third through hole 32 and the fourth through hole 33 on the second adjusting component 3. Taking the third through hole 32 as an example, during the rotation of the first adjusting component 2, the overlap area formed between the third through hole 32 and the first through hole 21 will change. When the overlap area between the third through hole 32 and the first through hole 21 increases, the water flow rate output from the third through hole 32 increases, thereby increasing the water output of the first outlet 12; conversely, when the overlap area between the third through hole 32 and the first through hole 21 decreases, the water flow rate output from the third through hole 32 decreases, thereby decreasing the water output of the first outlet 12.

[0028] Meanwhile, during the rotation of the first adjusting component 2, the change in the water flow rate of the third through hole 32 will be opposite to the change in the water flow rate of the fourth through hole 33. That is, when the water flow rate of the first outlet 12 increases, the water flow rate of the second outlet 13 will decrease accordingly.

[0029] During the adjustment of the water flow rate of the first outlet 12 and the second outlet 13, the water flow rate of the third through hole 32 and the fourth through hole 33 can be adjusted more accurately by controlling the overlap area between the through hole on the first adjusting component 2 and the through hole on the second adjusting component 3. Furthermore, the simpler structure and higher reliability of the first adjusting component 2, coupled with the reduced manufacturing costs, further simplify the process.

[0030] In one embodiment of this application, the first through hole 21 and the second through hole 22 are strip-shaped holes, and the first through hole 21 and the second through hole 22 extend around the axis of the first adjusting component 2.

[0031] Specifically, in order to improve the water flow adjustment accuracy of the first outlet 12 and the second outlet 13, the first through hole 21 and the second through hole 22 adopt a strip hole structure. In this way, during rotation, the strip hole and the through hole on the second adjusting component 3 can have a longer rotation stroke to adjust the overlap area, thereby allowing for more precise adjustment of the water flow rate.

[0032] During use, after rotating the first adjusting component 2, the first through hole 21 can rotate relative to the third through hole 32 along the length direction of its opening, thereby increasing the rotation angle range of the first adjusting component 2 and further refining the accuracy range of water flow adjustment.

[0033] In one embodiment of this application, the outer wall of the first adjusting component 2 is provided with a first strip groove 23, and the first through hole 21 is formed in the first strip groove 23; The first strip groove 23 is connected to the third through hole 32; the water flowing out of the first through hole 21 flows through the first strip groove 23 to the third through hole 32.

[0034] Specifically, in order to further increase the rotation angle of the first adjusting component 2 to more precisely adjust the water output of the first outlet 12, a first strip groove 23 can be additionally provided on the outer wall of the first adjusting component 2. The extending direction of the first strip groove 23 is the same as the extending direction of the first through hole 21, and the overall length of the first strip groove 23 is longer than that of the first through hole 21. In this way, the first strip groove 23 can further extend the state in which the first through hole 21 remains connected to the third through hole 32 during the rotation of the first adjusting component 2.

[0035] In one embodiment, the width of the first strip groove 23 gradually increases clockwise around the axis of the first adjusting member 2; the third through hole 32 is arranged at the end of the first strip groove 23 with a larger width dimension.

[0036] Specifically, by adopting a gradient design for the width of the first strip groove 23, the water flow rate can be further adjusted in conjunction with the width of the first strip groove 23 during the rotation of the first adjusting component 2, thereby improving the adjustment efficiency of the water flow rate.

[0037] In one embodiment of this application, the outer wall of the second adjusting component 3 is provided with a flow guiding groove 34, and the third through hole 32 is formed in the flow guiding groove 34, and the flow guiding groove 34 communicates with the first through hole 21.

[0038] Specifically, for the first water outlet 12, it is necessary to continuously supply cold water to the heating mechanism (such as heat exchanger) of the water heater during use. Therefore, in order to ensure that the first water outlet 12 can continuously flow out while increasing the rotation angle of the first adjusting component 2, a flow guiding groove 34 can be provided on the outer peripheral surface of the second adjusting component 3. The flow guiding groove 34 extends around the axis of the first adjusting component 2 and is arranged on the outer peripheral surface of the second adjusting component 3.

[0039] After the first adjusting component 2 is assembled onto the second adjusting component 3, the first through hole 21 will always be in communication with the flow guiding groove 34. That is, the projection of the first through hole 21 toward the axis of the first adjusting component 2 forms a projection overlap area with the flow guiding groove 34. In this way, the third through hole 32 can be ensured to be in communication with the first through hole 21 through the flow guiding groove 34, no matter where the first adjusting component 2 is rotated.

[0040] In this way, the first adjusting component 2 can have a wider range of rotation angles during use. For example... Figures 3-4 As shown, when the first outlet 12 is at its maximum flow rate, the first through hole 21, the third through hole 32, and the first outlet 12 are in a basically opposite state. During the process of reducing the flow rate of the first outlet 12, the first adjusting component 2 rotates, causing the overlapping area of ​​the first through hole 21 and the third through hole 32 to gradually decrease, thereby rapidly reducing the flow rate of the first outlet 12.

[0041] Meanwhile, as the first adjusting component 2 continues to rotate, the first through hole 21 and the third through hole 32 are completely offset, eliminating any overlap between them. At this point, the water flowing out of the third through hole 32 flows through the guide groove 34 to the first through hole 21 and then further through the first strip groove 23 to the first outlet 12. During this process, the gradually changing width of the first strip groove 23 allows for more precise adjustment of the water flow rate.

[0042] Furthermore, as the first adjusting component 2 continues to rotate, the second outlet 13 will connect with the fourth through hole 33 through the second through hole 22 to gradually increase the water output of the second outlet 13. Figure 5 and Figure 6 As shown, the water flow rate of the second outlet 13 is the largest. At this time, the second through hole 22, the fourth through hole 33 and the second outlet 13 are in a basically opposite state.

[0043] In one embodiment, one end of the flow guiding groove 34 is provided with the first through hole 21, and the other end of the flow guiding groove 34 is provided with an auxiliary water outlet hole 35.

[0044] Specifically, a first through hole 21 and an auxiliary water outlet hole 35 are respectively provided at both ends of the flow guide groove 34, which can ensure that the water volume distribution at different positions of the flow guide groove 34 is uniform.

[0045] In one embodiment of this application, the outer wall of the first adjusting component 2 is provided with a second strip groove 24, and the second through hole 22 is formed in the second strip groove 24; The second strip groove 24 is connected to the fourth through hole 33; the water flowing out of the second through hole 22 flows to the fourth through hole 33 through the second strip groove 24.

[0046] Specifically, in order to meet the requirement that the rotation angle of the first adjusting component 2 is large enough to refine the adjustment of the water flow rate, a second strip groove 24 can be provided on the outer wall of the first adjusting component 2. The second strip groove 24 can extend the length of the connecting flow path between the second through hole 22 and the second water outlet 13 to meet the rotation requirements of the first adjusting component 2.

[0047] In one embodiment, the width of the second strip groove 24 gradually decreases clockwise around the axis of the first adjusting member 2; the second through hole 22 is arranged at the end of the second strip groove 24 with a larger width dimension.

[0048] Specifically, during the rotation of the first adjusting component 2, the changing trend of the width of the connection between the second strip groove 24 and the second outlet 13 is opposite to the changing trend of the width of the connection between the first strip groove 23 and the first outlet 12. In this way, the ability to adjust the water flow quickly can be improved more effectively, thereby improving the ability to adjust the water temperature quickly.

[0049] In this process, after the first adjusting component 2 and the second adjusting component 3 are assembled together, a relatively sealed flow channel is formed between the flow guide groove 34 and the inner wall of the first adjusting component 2, and water flow is transported through the flow guide channel.

[0050] Similarly, a relatively sealed first strip flow channel is formed between the first strip groove 23 and the inner wall of the valve housing 1, so as to connect the first through hole 21 and the first outlet 12 through the first strip flow channel; a relatively sealed second strip flow channel is formed between the second strip groove 24 and the inner wall of the valve housing 1, so as to connect the second through hole 22 and the second outlet 13 through the second strip flow channel.

[0051] In one embodiment of this application, the second adjusting component 3 is provided with a limiting protrusion 36, and the first adjusting component 2 is provided with a limiting groove 25, wherein the limiting protrusion 36 is slidably disposed in the limiting groove 25; The limiting protrusion 36 and the limiting groove 25 are configured to limit the rotation angle of the first adjusting component 2.

[0052] Specifically, in order to control the rotation angle of the first adjusting component 2, the limiting protrusion 36 and the limiting slide 25 can cooperate with each other. The sliding of the limiting protrusion 36 relative to the limiting slide 25 can limit the rotation angle of the first adjusting component 2.

[0053] In one embodiment of this application, a mounting port 14 is provided at one end of the valve housing 1, and the first adjusting component 2 and the second adjusting component 3 are inserted into the valve housing 1 through the mounting port 14; A sealing plug 15 is provided in the mounting port 14, and the driving component 4 can rotatably seal through the sealing plug 15 and is connected to the first adjusting component 2; The valve housing 1 is also provided with an anti-rotation protrusion 16 inside, and the end of the second adjusting component 3 is provided with a positioning plane 37, and the anti-rotation protrusion 16 is in contact with the positioning plane 37.

[0054] Specifically, for ease of assembly, a mounting port 14 can be provided at one end of the valve housing 1. The first adjusting component 2 and the second adjusting component 3 are inserted into the valve housing 1 through the mounting port 14. After the first component and the second adjusting component 3 are inserted into the valve housing 1, the positioning plane 37 engages with the anti-rotation protrusion 16 to restrict the rotation of the second adjusting component 3 within the valve housing 1. Then, the sealing plug 15 is installed into the mounting port 14, and the drive component 4 passes through the sealing plug 15 and connects to the first adjusting component 2 inside the valve housing 1. The drive component 4 can be a drive structure such as a rotating shaft, and the rotation of the shaft can be controlled by a motor.

[0055] In one embodiment, the other end of the valve housing 1 is provided with the water inlet 11, and the side wall of the valve housing 1 is provided with the first water outlet 12 and the second water outlet 13.

[0056] Example 2, as Figure 11 As shown, this application provides a water heater, including a water heater body, the water heater body being provided with a main water inlet port 1000 and a main water outlet port 2000, the water heater body also being provided with a heating mechanism 3000, and further including the aforementioned water servo mechanism 4000; the water inlet of the water servo mechanism is connected to the main water inlet port, the first water outlet of the water servo mechanism is connected to the inlet of the heating mechanism, and the second water outlet of the water servo mechanism and the outlet of the heating mechanism are respectively connected to the main water outlet port.

[0057] Specifically, the water heater heats the water flowing into it through a heating mechanism, and the second outlet of the water servo mechanism 4000 can be connected to the water pipe between the heating mechanism 3000 and the main outlet port 2000 through a bypass pipe 5000, thereby realizing the direct delivery of cold water to the main outlet port 2000 through the bypass pipe 5000 to achieve the mixing of hot and cold water.

[0058] Compared with the prior art, the advantages and positive effects of this application are as follows: By setting a first adjusting component and a second adjusting component in the valve body, the first adjusting component can rotate outside the second adjusting component, and the second adjusting component can deliver water input from the inlet of the valve body. In actual use, by rotating the first adjusting component, the overlapping area of ​​the corresponding two through holes can be adjusted, thereby adjusting the water outlet area of ​​the third and fourth through holes, and thus adjusting the water flow rate of the first and second outlets. By adjusting the size of the overlapping area, the water flow rate can be adjusted accurately and quickly, thereby improving the water temperature adjustment accuracy and reducing manufacturing costs.

[0059] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
