[0051] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0052] It should be noted that in the description of this application, terms such as "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. This is merely for ease of description and does not indicate or imply that the device or element must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, it should not be understood as limiting this application. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0053] Example 1, as Figures 1-10 As shown, an embodiment of the present application provides a water servo mechanism, comprising:

[0054] A valve housing 1 is provided with a water inlet 11, a first water outlet 12 and a second water outlet 13;

[0055] A first adjusting component 2, which is a cylindrical structure, and a first through hole 21 and a second through hole 22 are provided on a side wall of the first adjusting component 2;

[0056] A second regulating member 3, wherein one end of the second regulating member 3 is provided with a water inlet 31, and a side wall of the first regulating member 2 is provided with a third through hole 32 and a fourth through hole 33, wherein the water inlet 31 is in communication with the third through hole 32 and the fourth through hole 33;

[0057] Driving component 4;

[0058] The first adjusting component 2 is sleeved on the outside of the second adjusting component 3. The first adjusting component 2 is rotatably disposed in the valve housing 1. The second adjusting component 3 is disposed inside the valve housing 1. The water inlet 31 is communicated with the water inlet 11. The third through hole 32 is arranged opposite to the first water outlet 12. The fourth through hole 33 is arranged opposite to the second water outlet 13.

[0059] In addition, the driving component 4 is arranged on the valve housing 1 and is configured to drive the first adjusting component 2 to rotate in the valve housing 1 to adjust the overlapping area formed between the first through hole 21 and the third through hole 32 and to adjust the overlapping area formed between the second through hole 22 and the fourth through hole 33.

[0060] Specifically, the valve housing 1 of the water servo mechanism is provided with a water inlet 11 for introducing water into the valve housing 1. The water entering the valve housing 1 flows through the water inlet 31 of the second regulating component 3 and enters the cavity formed within the second regulating component 3. The water flowing into the second regulating component 3 can flow out through the third through hole 32 and / or the fourth through hole 33 as needed. At the same time, the water flowing out of the second regulating component 3 will flow out through the first through hole 21 and / or the second through hole 22 as needed and ultimately be output through the first water outlet 12 and the second water outlet 13.

[0061] During the adjustment process, the first adjustment component 2 is rotated on the second adjustment component 3 by the driving component 4, thereby adjusting the opening area of ​​the third through hole 32 and the fourth through hole 33 on the second adjustment component 3. Taking the third through hole 32 as an example, during the rotation of the first adjustment component 2, the overlapping area between the third through hole 32 and the first through hole 21 will change. When the overlapping area between the third through hole 32 and the first through hole 21 increases, the water flow output from the third through hole 32 increases, thereby increasing the water output from the first water outlet 12. Conversely, when the overlapping area between the third through hole 32 and the first through hole 21 decreases, the water flow output from the third through hole 32 decreases, thereby reducing the water output from the first water outlet 12.

[0062] At the same time, 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 water outlet 12 increases, the water flow rate of the second water outlet 13 will decrease accordingly.

[0063] During the process of adjusting the water flow rate of the first water outlet 12 and the second water outlet 13, the water flow rate of the third through hole 32 and the fourth through hole 33 is synchronously adjusted by controlling the overlapping area of ​​the through hole of the first adjusting component 2 and the through hole of the second adjusting component 3. This allows for more accurate adjustment of the water flow rate of the first water outlet 12 and the second water outlet 13. Furthermore, the first adjusting component 2 is mounted on the second adjusting component 3, resulting in a simpler structure and higher reliability, which is also conducive to reducing manufacturing costs.

[0064] In one embodiment of the present application, the first through hole 21 and the second through hole 22 are bar-shaped holes, and the first through hole 21 and the second through hole 22 extend around the axis of the first adjusting component 2 .

[0065] Specifically, in order to improve the water outlet adjustment accuracy of the first water outlet 12 and the second water outlet 13, the first through hole 21 and the second through hole 22 adopt a strip hole structure. In this way, during the rotation process, the strip hole can have a longer rotation stroke with the through hole on the second adjustment component 3 to adjust the overlapping area, thereby being able to more finely adjust the water outlet flow.

[0066] 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 to further refine the accuracy range of water flow adjustment.

[0067] In one embodiment of the present application, a first strip-shaped groove 23 is provided on the outer wall of the first adjusting component 2 , and the first through hole 21 is formed in the first strip-shaped groove 23 ;

[0068] The first strip-shaped groove 23 is in communication with the third through hole 32 ; water flowing out of the first through hole 21 flows toward the third through hole 32 via the first strip-shaped groove 23 .

[0069] Specifically, in order to further increase the rotation angle of the first adjusting component 2 and to more precisely adjust the water output of the first water outlet 12, a first strip groove 23 may be additionally provided on the outer wall of the first adjusting component 2. The extension direction of the first strip groove 23 is the same as the extension direction of the first through hole 21, and the overall length of the first strip groove 23 is longer than the first through hole 21. In this way, the first strip groove 23 can further extend the state of the first through hole 21 to maintain the connection between the first through hole 21 and the third through hole 32 during the rotation of the first adjusting component 2.

[0070] In one embodiment, the width of the first strip-shaped groove 23 gradually increases in a clockwise direction around the axis of the first adjusting component 2 ; the third through hole 32 is arranged at the end of the first strip-shaped groove 23 where the width is larger.

[0071] Specifically, by adopting a gradual design for the width of the first strip groove 23, the width of the first strip groove 23 can be used to further adjust the water flow rate during the rotation of the first adjustment component 2, thereby improving the adjustment efficiency of the water flow rate.

[0072] In one embodiment of the present application, a guide groove 34 is provided on the outer wall of the second adjustment component 3 , the third through hole 32 is formed in the guide groove 34 , and the guide groove 34 is communicated with the first through hole 21 .

[0073] Specifically, for the first water outlet 12, it is necessary to continuously supply cold water to the heating mechanism of the water heater (such as a heat exchanger, etc.) during use. To this end, in the process of rotating the first adjusting component 2, in order to ensure that water can continue to flow out of the first water outlet 12 under the premise of increasing the rotation angle of the first adjusting component 2, a guide groove 34 can also be provided on the outer peripheral surface of the second adjusting component 3. The guide 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.

[0074] After the first adjustment component 2 is assembled onto the second adjustment component 3, the first through-hole 21 is always connected to the guide groove 34. That is, the projection of the first through-hole 21 toward the axis of the first adjustment component 2 forms an overlapping area with the guide groove 34. This ensures that the third through-hole 32 is connected to the first through-hole 21 via the guide groove 34, regardless of the position of the first adjustment component 2.

[0075] In this way, during use, the first adjustment component 2 can have more rotation angles. Figure 3-Figure 4 As shown, when the first water outlet 12 is at its maximum water flow rate, the first through hole 21, the third through hole 32, and the first water outlet 12 are substantially opposed to each other. In the process of reducing the water flow rate of the first water outlet 12, the first adjustment component 2 rotates, gradually reducing the overlapping area of ​​the first through hole 21 and the third through hole 32, thereby rapidly reducing the water flow rate of the first water outlet 12.

[0076] At the same time, as the first regulating member 2 continues to rotate, the first through-hole 21 and the third through-hole 32 are completely offset, leaving no overlap. Water flowing out of the third through-hole 32 then flows through the guide groove 34 to the first through-hole 21 and further through the first strip groove 23 to the first water outlet 12. During this process, the gradual width variation of the first strip groove 23 allows for more precise regulation of the water flow rate.

[0077] Furthermore, as the first regulating member 2 continues to rotate, the second water outlet 13 will be connected to the fourth through hole 33 through the second through hole 22 to gradually increase the water output of the second water outlet 13. Figure 5 and Figure 6 As shown, the water output of the second water outlet 13 is the largest. At this time, the second through hole 22, the fourth through hole 33 and the second water outlet 13 are in a substantially opposite state.

[0078] In one embodiment, the first through hole 21 is provided at one end of the guide groove 34 , and the auxiliary water outlet hole 35 is provided at the other end of the guide groove 34 .

[0079] Specifically, a first through hole 21 and an auxiliary water outlet hole 35 are respectively provided at both ends of the guide groove 34 , which can ensure that the water volume at different positions of the guide groove 34 is evenly distributed.

[0080] In one embodiment of the present application, a second strip-shaped groove 24 is provided on the outer wall of the first adjusting component 2 , and the second through hole 22 is formed in the second strip-shaped groove 24 ;

[0081] The second strip-shaped groove 24 is in communication with the fourth through hole 33 ; water flowing out of the second through hole 22 flows toward the fourth through hole 33 via the second strip-shaped groove 24 .

[0082] 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 also 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.

[0083] In one embodiment, the width of the second strip-shaped groove 24 gradually decreases in a clockwise direction around the axis of the first adjusting component 2 ; the second through hole 22 is arranged at the end of the second strip-shaped groove 24 where the width is larger.

[0084] Specifically, in the process of rotating the first adjusting component 2, the changing trend of the width of the connection part between the second strip groove 24 and the second water outlet 13 is opposite to the changing trend of the width of the connection part between the first strip groove 23 and the first water outlet 12. In this way, the ability to quickly adjust the water flow can be more effectively improved to improve the ability to quickly adjust the water temperature.

[0085] After the first regulating component 2 and the second regulating component 3 are assembled together, a relatively sealed diversion flow channel is formed between the diversion groove 34 and the inner wall of the first regulating component 2 , and water is transported through the diversion flow channel.

[0086] 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 with the first water 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 with the second water outlet 13 through the second strip flow channel.

[0087] In one embodiment of the present application, a limiting protrusion 36 is provided on the second adjusting component 3, and a limiting sliding groove 25 is provided on the first adjusting component 2, and the limiting protrusion 36 is slidably provided in the limiting sliding groove 25;

[0088] The limiting protrusion 36 cooperates with the limiting sliding groove 25 to limit the rotation angle of the first adjusting component 2 .

[0089] Specifically, in order to control the rotation angle of the first adjusting component 2, it can be achieved by the cooperation between the limiting protrusion 36 and the limiting slide groove 25. The sliding of the limiting protrusion 36 relative to the limiting slide groove 25 can limit the rotation angle of the first adjusting component 2.

[0090] In one embodiment of the present 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 ;

[0091] A sealing plug 15 is provided in the installation opening 14 , and the driving component 4 rotatably and sealably passes through the sealing plug 15 and is connected to the first adjusting component 2 ;

[0092] An anti-rotation protrusion 16 is further provided inside the valve housing 1 , and a positioning plane 37 is provided at the end of the second adjusting component 3 , and the anti-rotation protrusion 16 is in contact with the positioning plane 37 .

[0093] Specifically, to facilitate assembly, a mounting port 14 can be provided at one end of the valve housing 1, through which the first and second adjusting components 2 and 3 are installed into the valve housing 1. After the first and second adjusting components 3 are installed into the valve housing 1, the positioning flat surface 37 cooperates with the anti-rotation protrusion 16 to restrict the second adjusting component 3 from rotating within the valve housing 1. The sealing plug 15 is then installed into the mounting port 14, and the drive component 4 seals through the sealing plug 15 and connects to the first adjusting component 2 within the valve housing 1. The drive component 4 can be a drive structure such as a rotating shaft, and can be driven by a motor to rotate the rotating shaft to control the rotation of the first adjusting component 2.

[0094] In one embodiment, the water inlet 11 is provided at the other end of the valve housing 1 , and the first water outlet 12 and the second water outlet 13 are provided on the side wall of the valve housing 1 .

[0095] Example 2, as Figure 11 As shown, the present application provides a water heater, including a water heater body, wherein the water heater body is provided with a total water inlet port 1000 and a total water outlet port 2000, the water heater body is also provided with a heating mechanism 3000, and also includes the above-mentioned water servo mechanism 4000; the water inlet of the water servo mechanism is connected to the total 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 total water outlet port.

[0096] Specifically, the water heater heats the water flowing into it through a heating mechanism, and the second water outlet of the water servo mechanism 4000 can be connected to the water pipe between the heating mechanism 3000 and the main water outlet port 2000 through a bypass pipe 5000, thereby directly delivering cold water to the main water outlet port 2000 through the bypass pipe 5000 to achieve mixing of cold and hot water.

[0097] Compared with the prior art, the advantages and positive effects of the present application are: by arranging a first adjusting component and a second adjusting component in the valve housing, the first adjusting component can rotate outside the second adjusting component, and the second adjusting component can transport water input from the water inlet of the valve housing. In this way, in actual use, the overlapping area of ​​the corresponding two through holes is adjusted by rotating the first adjusting component to adjust the water outlet area of ​​the third through hole and the fourth through hole, thereby achieving the adjustment of the water outlet flow rate of the first water outlet and the second water outlet. By adjusting the size of the overlapping area, the water outlet can be adjusted accurately and quickly, thereby improving the water temperature regulation accuracy and reducing the manufacturing cost.

[0098] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions claimed to be protected by the present application.
