Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

First embodiment, as shown in fig. 1 to 9, the water servo mechanism of the present embodiment includes:

the water inlet pipe 11, the first water outlet pipe 12 and the second water outlet pipe 13 are arranged on the valve casing 1;

the valve core assembly 2, the valve core assembly 2 includes a driving part 21, a first flow control part 22 and a second flow control part 23, the first flow control part 22 and the second flow control part 23 are arranged in the valve housing 1, the first flow control part 22 is arranged at the first water outlet pipe 12 and is used for controlling the flow of the first water outlet pipe 12, and the second flow control part 23 is arranged at the second water outlet pipe 13 and is used for controlling the flow of the second water outlet pipe 13;

wherein the water servo has a first position, a second position, and a third position;

in the process that the water servo mechanism operates from a first position, a second position and a third position in sequence, the driving part 21 is used for driving the first flow control part 22 to gradually reduce the flow of the first water outlet pipe 12, and in the process of reverse operation, the driving part 21 is used for driving the first flow control part 22 to gradually increase the flow of the first water outlet pipe 12;

in the process that the water servo mechanism runs from the second position to the third position, the driving part 21 is used for driving the second flow control part 23 to gradually increase the flow of the first water outlet pipe 12, and in the process of reverse running, the driving part 21 is used for driving the second flow control part 23 to gradually decrease the flow of the first water outlet pipe 12.

Specifically, the water servo mechanism is assembled by the valve housing 1 and the valve core assembly 2, wherein the valve housing 1 is configured with the water inlet pipe 11, the first water outlet pipe 12 and the second water outlet pipe 13, so that the valve housing 1 is integrally in a three-way structure.

During assembly, the driving component 21, the first flow control component 22 and the second flow control component 23 are assembled on the valve housing 1, the driving component 21 can drive the first flow control component 22 and the second flow control component 23 to move in the valve housing 1, the moving first flow control component 22 can adjust the water outlet flow of the first water outlet pipe 12, and similarly, the second flow control component 23 can adjust the water outlet flow of the second water outlet pipe 13.

The water servo has three specific positions, specifically: when the water servo mechanism is in the first position, the first flow control part 22 controls the first water outlet pipe 12 to be in the maximum opening degree, and the second flow control part 23 closes the second water outlet pipe 13; when the water servo mechanism is in the second position, the second flow control part 23 is in a critical state for opening and closing the second water outlet pipe 13; in the state of the water servo mechanism at the third position, the first flow control part 22 controls the first water outlet pipe 12 to be at the minimum opening degree, and the second flow control part 23 controls the second water outlet pipe 13 to be at the maximum opening degree.

In an embodiment of the present application, during the operation of the water servo mechanism from the first position to the second position, the second flow control component 23 closes the second water outlet pipe 13, and during the reverse operation, the second flow control component 23 closes the second water outlet pipe 13.

In the practical application process, the water servo mechanism is installed on the water heater. For a water heater, the water heater generally comprises a water heater main body, wherein the water heater main body is provided with a total water inlet port and a total water outlet port, the water heater main body is also provided with a heating mechanism, and the water heater also comprises the water servo mechanism; the inlet tube of the water servo mechanism is connected with the total water inlet port, the first water outlet tube of the water servo mechanism is connected with the inlet of the heating mechanism, and the second water outlet tube of the water servo mechanism is connected with the outlet of the heating mechanism respectively. The main water inlet port is connected to a water supply pipe (such as a tap water pipe) in the home of the user, and the main water outlet port is connected to a water terminal (such as a shower or a faucet) through the water pipe in the home of the user.

In a specific use process, the water using terminal is opened to output hot water outwards, and at the moment, the heating mechanism is started to heat water flowing through.

As shown in fig. 10-14, the dashed arrows represent the direction of water flow.

In the normal heating process, as shown in fig. 10, the water servo mechanism is at the first position, and at this time, the first flow control component 22 adjusts the first water outlet pipe 12 to be at the maximum opening degree, so as to obtain the maximum water flow; meanwhile, the second flow control member 23 is in a position to close the second water outlet pipe 13, that is, the bypass flow path is in a cut-off position.

In the normal water using process, the power of the heating mechanism is reduced due to the influence of external factors, and at this time, the flow rate of the first water outlet pipe 12 needs to be adjusted. At this point, the water servo will change between the first position and the second position. As shown in fig. 11, the driving component 21 acts to drive the first flow control component 22 and the second flow control component 23 to act, and the first flow control component 22 correspondingly adjusts the opening degree of the first water outlet pipe 12 to reduce the water flow rate so as to maintain the water temperature output by the water heater to be constant; whereas the second outlet pipe 13 is not opened for the second flow control member 23. In the process, the driving part 21 drives the first flow control part 22 to move in the forward and reverse directions according to the difference value between the outlet water temperature of the water heater and the set temperature, so as to dynamically adjust the outlet water temperature.

In the case of a water heater with a continuously higher outlet temperature, the water flow into the heating mechanism needs to be further reduced, and the bypass water flow is turned on. At this time, the water servo mechanism will change between the second position and the third position, the driving part 21 will act to drive the first flow control part 22 and the second flow control part 23 to act, the first flow control part 22 will correspondingly decrease the opening degree of the first water outlet pipe 12 to decrease the water flow, and correspondingly, the first flow control part 22 will correspondingly increase the opening degree of the first water outlet pipe 12 to increase the water flow. Therefore, in the process that the water control device changes between the second position and the third position, the water flow proportion of the first water outlet pipe 12 and the second water outlet pipe 13 can be regulated, and the bypass ratio can be further dynamically regulated, so that the water temperature output by the water heater can be kept constant.

In addition, when the user normally uses the water heater, when the user uses water for the second time in a short time, the water servo mechanism changes between the second position and the third position to reduce the flow rate of cold water flowing into the heating mechanism, and the mixing ratio of hot water and cold water output by the heating mechanism is reduced to improve the lowest temperature of water flowing out of the water heater and reduce the highest temperature of water flowing out of the water heater, so that the requirement of constant temperature water outlet of the water heater is met, and the shower experience of the user is improved.

In an embodiment of the present application, the first flow control member 22 includes a rotating moving member 221 and a first shielding member 222, and the first shielding member 222 is disposed on the rotating moving member 221;

the second flow control member 23 includes a mounting member 231 and a second shielding member 232, the second shielding member 232 being disposed on the mounting member 231;

the driving member 21 is connected to the rotating moving member 221 and is used for driving the rotating moving member 221 to rotate, the rotating moving member 221 rotates relative to the valve housing 1 and also moves relative to the valve housing 1, the first shielding member 222 is disposed in the valve housing 1 and located at one side of the first water outlet pipe 12, the mounting member 231 is slidably disposed on the rotating moving member 221, and the second shielding member 232 is disposed opposite to the second water outlet pipe 13.

Specifically, as for the first flow control member 22, the rotational movement member 221 is connected to the driving member 21 outside the valve housing 1 to rotate the rotational movement member 221 by the driving member 21. While the rotationally displaceable part 221 is driven in rotation relative to the valve housing 1 by the drive member 21, the rotationally displaceable part 221 can also be displaced along its axis relative to the valve housing 1.

In this way, in the process of adjusting the opening degree of the first water outlet pipe 12 to control the water flow rate, the first shielding part 222 is arranged on the pipe orifice side of the first water outlet pipe 12, and the flow rate of the first water outlet pipe 12 is adjusted in a rotating manner. The first blocking component 222 adjusts the flow rate of the first water outlet pipe 12 in a rotating manner, so that the flow rate adjustment is more accurate, and the requirement of gradual step-by-step adjustment is met, so as to meet the requirement of adjusting the flow rate of water entering the heating mechanism under different working conditions of the water heater.

In the process of adjusting the opening of the second water outlet pipe 13 to control the water flow, the second shielding part 232 is arranged opposite to the pipe orifice of the second water outlet pipe 13, and the flow of the second water outlet pipe 13 is adjusted by adopting a relative movement mode. The second shielding part 232 adjusts the flow of the second water outlet pipe 13 in a relative movement manner, so that the flow can be adjusted more efficiently, the water temperature can be adjusted quickly, and the requirement of constant-temperature water outlet of the water heater can be met.

In another embodiment of the present application, the first shielding member 222 is a sleeve structure, a water flow passage is formed between the first shielding member 222 and the rotating member 221, and a water flow opening 2221 is formed in a side wall of the first shielding member 222; the water flowing in from the water inlet pipe 11 flows into the first water outlet pipe 12 through the water flow passage and the water through port 2221 in sequence.

Specifically, in order to conveniently adjust the flow rate of the first water outlet pipe 12 by adopting a rotating manner, the first shielding part 222 adopts a sleeve structure, the first shielding part 222 is arranged on the rotating moving part 221 and rotates along with the rotating moving part, the water opening 2221 can rotate relative to the pipe orifice of the first water outlet pipe 12, and in the rotating process, the overlapping area of the water opening 2221 and the pipe orifice of the first water outlet pipe 12 is changed, so as to dynamically adjust the flow rate of the first water outlet pipe 12.

In an embodiment, the outer surface of the sidewall of the first shielding member 222 is further provided with a water groove 2222 communicated with the water opening 2221, and the water groove 2222 extends around the axis of the rotating member 221 in a direction away from the water opening 2221.

Specifically, in the adjusting process, the water flow rate of the first water outlet pipe 12 can be adjusted quickly by adjusting the overlapping area of the water through opening 2221 and the pipe opening of the first water outlet pipe 12. After the water through port 2221 and the pipe orifice of the first water outlet pipe 12 are staggered, the water tank 2222 and the pipe orifice of the first water outlet pipe 12 are kept in a communicated state, and further, more accurate water flow rate adjustment can be performed through the water tank 2222.

In one embodiment, the water flow cross-sectional area of the water tank 2222 gradually decreases in a direction away from the water opening 2221 around the axis of the rotational movement member 221. Specifically, the water flow cross-sectional area of the water tank 2222 is gradually changed, so that the water flow at the pipe orifice of the first water outlet pipe can be more finely and accurately adjusted in the process that the driving part 21 drives the rotating moving part 221 to rotate in one direction.

The basin 2222 of gradual change structure can reach more accurate regulation carrying out the high accuracy bypass and than the adjustment in-process, and then the accurate outlet water temperature who adjusts the water heater to satisfy more accurate temperature and adjust.

In some embodiments, a first partition 121 is disposed in the first water outlet pipe 12, a first water outlet 122 is disposed on the first partition 121, and the first water outlet 122 is configured to communicate with the water inlet 2221 and the water tank 2222.

Specifically, in order to conveniently control the opening of the first water outlet pipe 12 to precisely adjust the water flow, the first partition 121 is provided with a first water outlet 122 matched with the water inlet 2221 and the water tank 2222. In the process that the first shielding part 222 rotates along with the rotating and moving part 221, the water through opening 2221 and the water tank 2222 can rotate relative to the first water outlet 122 and communicate with each other, so as to control the outlet flow of the first water outlet pipe 12 more accurately.

In some embodiments, the first partition 121 is further provided with an auxiliary water outlet 123, and the water inlet pipe 11 is communicated with the auxiliary water outlet 123.

Specifically, the auxiliary water outlet 123 is configured on the first partition plate 121, and the auxiliary water outlet 123 is in a normally open state and is always communicated with the water inlet pipe 11, so that the basic water flow requirement of the first water outlet pipe 12 can be ensured through the auxiliary water outlet 123.

The first water outlet 122 may be a strip-shaped hole extending around the axial direction of the rotating member 221.

Specifically, the first water outlet 122 of the strip-shaped hole structure can be better matched with the water through opening 2221 and the water tank 2222 on the first shielding part 222, and in the rotating process of the first shielding part 222, the water through opening 2221 and the water tank 2222 are sequentially overlapped and matched along the length direction of the first water outlet 122, so that the matching degree can be improved, and the effect of accurately controlling the water flow rate can be met.

Since the first partition 121 is provided with the first water outlet 122 and the auxiliary water outlet 123, in order to more precisely control and adjust the water flow rate of the first water outlet pipe 12, the first water outlet 122 is sequentially communicated with the water through port 2221 and the water tank 2222 in the process that the water servo mechanism sequentially operates from the first position, the second position and the third position.

In another embodiment, a second partition 131 is disposed in the second water outlet pipe 13, and a second water outlet 132 is disposed on the second partition 131.

Specifically, for the second water outlet pipe 13, in order to meet the requirement of accurately regulating the water flow, a second partition 131 may be disposed inside the second water outlet pipe 13, a second water outlet 132 is correspondingly disposed on the second partition 131, and the second water outlet 132 is disposed opposite to the second flow control member 23. During the flow control process, the second flow control part 23 moves along with the rotating moving part 221, and the second shielding part 232 in the second flow control part 23 can open and close the second water outlet 132 during the moving process, and the precise adjustment of the water flow of the second water outlet 132 is realized by controlling the distance between the second shielding part 232 and the second water outlet 132.

In one embodiment, the water outlet areas of the auxiliary water outlet 123 and the second water outlet 132 are designed to be the same, so that after the water servo mechanism is at the third position, the first water outlet 122 is blocked by the first blocking part 222, the first water outlet pipe 12 enters water through the auxiliary water outlet 123, and meanwhile, the second water outlet 132 in the second water outlet pipe 13 is completely opened. So as to realize that the water outlet flow rates of the auxiliary water outlet 123 and the second water outlet 132 are substantially the same, and further satisfy the condition that the water outlet flow rates of the first water outlet pipe 12 and the second water outlet pipe 13 are substantially the same.

In this state, the water servo controls the water flow through the small area of the auxiliary water outlet 123 and the second water outlet 132, so that the total water inflow of the water servo is reduced, the heat in the heating mechanism in the water heater is released more slowly, the lowest point of the water temperature of the mixed water is larger, and the water temperature approaches to the target water outlet temperature, thereby improving the user experience.

In one embodiment, in order to stably and firmly mount the rotating and moving member 221 so as to ensure that the rotating and moving member 221 can smoothly move while rotating inside the valve housing 1, the second partition plate 131 is further provided with a supporting hole 133, and the other end portion of the rotating and moving member 221 is inserted into the supporting hole 133.

Specifically, during the assembly process, the rotational movement member 221 is inserted into the valve housing 1 such that one end portion of the rotational movement member 221 is inserted into the support hole 133, and then the other end portion is connected to the driving member 21 outside the valve housing 1. Thus, both end portions of the rotational movement member 221 can be supported well to ensure stable rotation and movement of the rotational movement member 221 within the valve housing 1.

In some embodiments, the second outlet pipe 13 is in a closed state when the water servo is operated between the first position and the second position, and the second outlet pipe 13 is in an open state when the water servo is operated between the second position and the third position. The mounting member 231 is also designed to be a sleeve structure, the mounting member 231 is sleeved on the rotating member 221, an elastic member 233 is further arranged between the mounting member 231 and the rotating member 221, and the elastic member 233 is used for applying an elastic force to the mounting member 231 towards the second partition 131; the other end portion of the rotational movement member 221 is provided with a stopper 223, and the stopper 223 is located between the second partition 131 and the mounting member 231.

Specifically, the mounting member 231 is fitted over the rotating member 221, and the mounting member 231 is slidable with respect to the rotating member 221, and the elastic member 233 functions to apply an elastic force to the mounting member 231.
