Background Art

[0002] In some water vapor generating equipment, water vapor can be prepared by using a water pump to pump high-temperature hot water into the water inlet pipe, and then spraying the high-temperature hot water into the low-pressure environment provided by the tank through a spray assembly. Then, the prepared water vapor will be transported to the demand side through relevant pipelines. When the load on the demand side changes, the operating frequency of the water pump needs to be adjusted accordingly to control the amount of water vapor prepared. However, due to some factors, the amount of water vapor prepared will not change linearly with the adjustment of the operating frequency of the water pump. Therefore, how to accurately control the amount of water vapor prepared has become an urgent problem to be solved. Summary of the invention

[0031] DETAILED DESCRIPTION

[0032] In order to make the features and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0033] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0034] In the following, the terms "first" and "second" are used for descriptive purposes only and should not be understood as suggesting or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0035] The following are detailed descriptions respectively. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0036] In one application scenario of the water vapor generating device, the water vapor generating device can be used as a part of the water vapor compression system to prepare the water vapor required by the water vapor compression system. Figure 1 , Figure 1 It is a structural schematic diagram of a water vapor compression system provided in an embodiment of the present application.

[0037] On the one hand, the heat source water enters the heat pump 1200 from the heat source water inlet A1. On the other hand, the water for steam generation enters the heat pump 1200 from the water for steam generation inlet B1. In the heat pump 1200, the heat source water and the water for steam generation exchange heat, so that the water for steam generation becomes high-temperature water. In addition, the temperature of the heat source water after heat exchange is reduced and it will be discharged from the heat source water outlet A2.

[0038] The water pump 2200 of the water vapor heat exchange device pumps the high-temperature water discharged from the heat pump 1200 to the water inlet pipe 2300 of the water vapor heat exchange device, and transports it to the spray assembly 2400 of the water vapor heat exchange device through the water inlet pipe 2300.

[0039] Among them, a part of the water inlet pipe 2300 connected to the spray assembly 2400 extends into the receiving chamber of the tank body 2100 of the water vapor heat exchange device, and the spray assembly 2400 is also in the receiving chamber of the tank body 2100. Generally speaking, the pressure of the receiving chamber of the tank body 2100 is lower than the pressure of the water inlet pipe 2300, that is, the receiving chamber of the tank body 2100 provides a relatively low-pressure environment. Due to the pressure difference between the water inlet pipe 2300 and the receiving chamber of the tank body 2100, the high-temperature water in the water inlet pipe 2300 will be sprayed into the receiving chamber of the tank body 2100 by the spray assembly 2400. In the process of the high-temperature water being sprayed into the receiving chamber of the tank body 2100 by the spray assembly 2400 through the water inlet pipe 2300, due to the sudden decrease in pressure, a part of the high-temperature water quickly boils and vaporizes into water vapor, and the other part of the high-temperature water remains in liquid state, or is called liquid water.

[0040] It should be noted that, in a possible implementation, the tank body 2100 is a flash tank, the principle of which is to use the difference in saturated vapor pressure of a substance at different temperatures to rapidly evaporate a liquid substance by reducing pressure. The high-pressure and high-temperature fluid enters the flash tank after decompression, at which point the fluid temperature is higher than the boiling point after decompression, and rapidly boils and vaporizes, and the two phases are separated. The function of the flash tank is to provide space for rapid vaporization of the fluid and separation of vapor and liquid, and is widely used in the chemical, food, pharmaceutical and other industries to achieve efficient recovery and reuse of resources.

[0041] Furthermore, the water vapor in the tank 2100 will be transmitted to the gas-liquid separator 1300 through relevant pipelines, and the liquid water in the tank 2100 will also be pumped to the gas-liquid separator 1300 by the system water pump 1600. Then, the water vapor in the gas-liquid separator 1300 is transmitted to the water vapor compressor 1400, and the water vapor is compressed by the water vapor compressor 1400 to obtain high-temperature and high-pressure water vapor. The high-temperature and high-pressure water vapor is discharged from the water vapor compression system 1000 through the water vapor outlet C1.

[0042] In addition, the first system control valve 1100 in the water vapor compression system 1000 is used to control the pipeline switch between the water inlet B1 for water vapor generation and the heat pump 1200; the second system control valve 1500 is used to control the pipeline switch between the water vapor compressor 1400 and the water vapor outlet C1; the third system control valve 1700 is used to control the pipeline switch between the tank body 2100 and the heat pump 1200.

[0043] It can be seen that the gas-liquid separator 1300, the water vapor compressor 1400, and the second system control valve 1500 constitute the demand side of the water vapor generating device 2000. When the load on the demand side changes, the operating frequency of the water pump 2200 needs to be adjusted accordingly to control the amount of water vapor prepared. It should be noted that the above-mentioned demand side is not limited to being composed of the gas-liquid separator 1300, the water vapor compressor 1400, and the second system control valve 1500. The demand side refers to the components or equipment collection that need to use the water vapor prepared by the water vapor generating device 2000.

[0044] It is understandable that changing the operating frequency of the water pump 2200 will cause the pressure of the water inlet pipe 2300 to change accordingly, thereby changing the pressure difference between the water inlet pipe 2300 and the water vapor chamber 2110 of the tank body 2100, affecting the spraying effect of the spray assembly 2400.

[0045] Specifically, during the process of high-temperature water being sprayed from the spray assembly 2400, it is broken into countless tiny droplets. The diameter of these droplets can also be called the spray particle size. The spray effect of the spray assembly 2400 is specifically manifested as the spray particle size. The size of the spray particle size has a significant impact on the amount of water vapor produced. When the spray particle size is larger, the vapor-liquid contact area is reduced, the heat exchange efficiency is reduced, and some droplets may remain in liquid state due to failure to fully absorb heat, thereby reducing the amount of water vapor produced. On the contrary, when the spray particle size is smaller, the vapor-liquid contact area is increased, the heat exchange efficiency is improved, and the droplets can absorb heat more quickly and vaporize, thereby producing more water vapor in the same time, thereby increasing the amount of water vapor produced.

[0046] Since the operating frequency of the water pump 2200 changes, the front and rear pressure difference and the spraying effect of the spray assembly 2400 are affected, which leads to a decrease in the linearity between the water vapor production amount and the operating frequency of the water pump 2200, making it difficult to accurately control the water vapor production amount.

[0047] In view of the above problems, this application proposes a structure of a water vapor generating device, see Figure 2 - Figure 6 .

[0048] like Figure 2 As shown, the water vapor generating device 2000 includes a tank body 2100, a water pump 2200, a water inlet pipe 2300, a plurality of spray assemblies 2400, and a control valve 2500 corresponding to each of the plurality of spray assemblies 2400. The water pump 2200 is connected to the water inlet pipe 2300, and the water inlet pipe 2300 is connected to the water vapor chamber 2110 of the tank body 2100 through the plurality of spray assemblies 2400. The water pump 2200 and the water inlet pipe 2300 not shown in full can be seen in FIG. Figure 1 .

[0049] In order to monitor the pressure difference between the water inlet pipe 2300 and the water vapor chamber 2110 of the tank body 2100, a first pressure sensor 2610 is provided at the first water inlet pipe 2310 of the water vapor generating device 2000, and a second pressure sensor 2620 is provided in the water vapor containing chamber of the tank body 2100. The water pump 2200 is provided at the water inlet end of the first water inlet pipe 2310, that is, the first water inlet pipe 2310 is the water inlet main pipe in the water inlet pipe 2300 of the water vapor generating device 2000, and the water inlet pipe 2300 also includes Figure 2 The water inlet branch pipe not shown in the figure. The first pressure sensor 2610 is arranged at the first water inlet pipe 2310, so that the pressure value can be accurately collected to characterize the pressure of the entire water inlet pipe 2300. It can be understood that the exhaust port 2130 and the drain port 2140 of the tank body 2100 are respectively connected to the demand side; the exhaust port 2130 conveys water vapor to the demand side; the drain port 2140 conveys liquid water to the demand side; and the sewage outlet 2150 is used to discharge the dirt accumulated in the tank body. In addition, the first temperature sensor 2710 arranged at the first water inlet pipe 2310 can collect the temperature value of the first water inlet pipe 2310; the second temperature sensor 2720 arranged in the water vapor chamber 2110 of the tank body 2100 can collect the temperature value of the water vapor chamber 2110 of the tank body 2100; the second temperature sensor 2730 arranged in the liquid chamber 2120 of the tank body 2100 can collect the temperature value of the water vapor chamber 2120 of the tank body 2100.

[0050] In order to control the working state of each spray assembly 2400 , this embodiment proposes to add a control valve 2500 to the steam generating device 2000 .

[0051] like Figure 3 As shown, the water inlet pipe 2300 includes a first water inlet pipe 2310, a second water inlet pipe 2320 and a third water inlet pipe 2330, and the control valve 2500 includes a first control valve 2510 arranged on the first water inlet pipe 2310 and a second control valve 2520 arranged on the third water inlet pipe 2330; the water outlet end of the first water inlet pipe 2310 is respectively connected to the water inlet ends of the second water inlet pipe 2320 and the third water inlet pipe 2330; the water pump 2200 is arranged at the water inlet end of the first water inlet pipe 2310; and each spray assembly 2400 is arranged at the water outlet end of a second water inlet pipe 2320 or a water outlet end of a third water inlet pipe 2330. It can be understood that controlling the first control valve 2510 will affect the water inlet of the first water inlet pipe 2310, the second water inlet pipe 2320, and the third water inlet pipe 2330; when the first control valve 2510 is in an open state, controlling any second control valve 2520 will individually affect the water inlet of the third water inlet pipe 2330 where the second control valve 2520 is located.

[0052] like Figure 4As shown, the water inlet pipe 2300 includes a first water inlet pipe 2310 and a plurality of third water inlet pipes 2330, the control valve 2500 includes a first control valve 2510 disposed on the first water inlet pipe 2310 and a second control valve 2520 disposed on the third water inlet pipe 2330; the water outlet end of the first water inlet pipe 2310 is respectively connected to the water inlet ends of the plurality of third water inlet pipes 2330; the water pump 2200 is disposed on the water inlet end of the first water inlet pipe 2310; and each spray assembly 2400 is disposed on the water outlet end of a third water inlet pipe 2330. It can be understood that controlling any second control valve 2520 will individually affect the water inflow of the third water inlet pipe 2330 where the second control valve 2520 is located.

[0053] like Figure 5 As shown, the water inlet pipe 2300 includes a first water inlet pipe 2310 and a plurality of second water inlet pipes 2320, and the control valve 2500 includes a third control valve ( Figure 5 The outlet end of the first water inlet pipe 2310 is respectively connected to the water inlet ends of the plurality of second water inlet pipes 2320; the water pump 2200 is disposed at the water inlet end of the first water inlet pipe 2310; and each spray assembly 2400 is disposed at the water outlet end of a second water inlet pipe 2320. It is understood that a corresponding third control valve is disposed at each spray assembly 2400, and the state of the corresponding spray assembly 2400 can be individually controlled by the third control valve.

[0054] like Figure 6 As shown, the number of the first control valves 2510 in the first water inlet pipe 2310 can be multiple, and the opening or closing of any first control valve 2510 will affect the third water inlet pipe 2330 in the water outlet direction thereof. Figure 6 The third water inlet pipe 2330 is only used as an example. The third water inlet pipe 2330 can also be partially or completely replaced by Figure 3 The second water inlet pipe 2320 in the embodiment is not limited thereto.

[0055] In addition to the above-mentioned setting method of the control valve, the setting position of the control valve can also be adjusted according to needs, so that the working state of the spray assembly corresponding to the target control valve can be adjusted by controlling the target control valve.

[0056] based on Figure 1 The scene shown is schematic. Figure 2 - Figure 6 The structure of the water vapor generating device will be combined with Figure 7 - Fig.14 , the control method of the water vapor generating equipment provided in the embodiment of the present application is introduced in detail.

[0057] See also Figure 7 , Figure 7A flow chart of a control method for a water vapor generating device provided in an embodiment of the present application. The water vapor generating device includes a tank body, a water pump, a water inlet pipe, a plurality of spray assemblies, and a control valve corresponding to each of the plurality of spray assemblies. The water pump is connected to the water inlet pipe, and the water inlet pipe is connected to the water vapor chamber of the tank body through the plurality of spray assemblies. Figure 7 As shown, the method of the embodiment of the present application may include the following steps S101-S103.

[0058] S101, after adjusting the working frequency of the water pump, obtaining the pressure difference between the water inlet pipe and the water vapor chamber of the tank body.

[0059] Specifically, the water vapor generating device will continuously monitor the pressure value of the water inlet pipe and the pressure value of the water vapor chamber of the tank. Among them, the pressure value of the water inlet pipe is greater than the pressure value of the water vapor chamber of the tank, so that the high-temperature hot water in the water inlet pipe can be sprayed to the water vapor chamber of the tank through the spray assembly. When the load on the demand side decreases, the demand for water vapor decreases, and the water vapor generating device monitors that the pressure value of the water vapor chamber of the tank increases; when the load on the demand side increases, the demand for water vapor increases, and the water vapor generating device monitors that the pressure value of the water vapor chamber of the tank decreases. When the pressure value of the water vapor chamber of the tank rises or falls above a certain threshold, it will trigger the water vapor generating device to adjust the working frequency of the water pump to control the amount of water vapor prepared.

[0060] After adjusting the working frequency of the water pump, the pressure difference between the water inlet pipe and the water vapor chamber of the tank body will also change. Furthermore, it is necessary to obtain the pressure value of the water inlet pipe collected by the first pressure sensor and the pressure value of the water vapor chamber of the tank body collected by the second pressure sensor; according to the pressure value of the water inlet pipe and the pressure value of the water vapor chamber of the tank body, determine the pressure difference between the water inlet pipe and the water vapor chamber of the tank body. For the setting positions of the first pressure sensor and the second pressure sensor, please refer to Figure 2 , I will not go into details here.

[0061] S102: If the pressure difference between the water inlet pipe and the water vapor chamber of the tank body is not within a preset pressure difference range, a target control valve is determined from the control valves corresponding to each spray assembly.

[0062] Specifically, the preset pressure difference range involved in this embodiment is set according to the actual operation and control requirements of the water vapor generating device. It represents an ideal pressure difference interval. Within this pressure difference interval, the spray effect of the spray assembly meets the requirements, and the linear relationship between the water vapor preparation amount and the working frequency of the water pump is also relatively close. When the pressure difference between the water inlet pipe and the water vapor chamber of the tank body is not within the preset pressure difference range, it is necessary to adjust the working state of the spray assembly. In order to achieve this adjustment, the water vapor generating device will select one or more control valves as the target control valves according to the state of the control valves corresponding to the current spray assemblies (such as open or closed) and the degree of their influence on the pressure difference between the water inlet pipe and the water vapor chamber of the tank body.

[0063] S103, controlling the target control valve to adjust the working state of the spray assembly corresponding to the target control valve so that the pressure difference between the water inlet pipe and the water vapor chamber of the tank body falls within a preset pressure difference range.

[0064] Specifically, the water vapor generating device issues a corresponding control instruction according to the determined target control valve to open or close the target control valve. By adjusting the state of the target control valve, the working state of the spray assembly corresponding to the target control valve can be changed, thereby adjusting the pressure difference between the water inlet pipe and the water vapor chamber of the tank body.

[0065] It can be understood that if the target control valve is closed, the working state of the spray assembly corresponding to the target control valve will also change from an open state to a closed state. At this time, the number of spray assemblies that can effectively spray will decrease, and the pressure value of the water inlet pipe will also increase accordingly; if the target control valve is opened, the working state of the spray assembly corresponding to the target control valve will also change from a closed state to an open state. At this time, the number of spray assemblies that can effectively spray will increase, and the pressure value of the water inlet pipe will also decrease accordingly.

[0066] In some cases, the target control valve can be controlled to make the pressure difference between the water inlet pipe and the water vapor chamber of the tank body fall within the preset pressure difference range. In some cases, if the target control valve cannot be controlled to make the pressure difference between the water inlet pipe and the water vapor chamber of the tank body fall within the preset pressure difference range, then steps S102-S103 can be repeatedly performed until the pressure difference between the water inlet pipe and the water vapor chamber of the tank body falls within the preset pressure difference range.

[0067] In this embodiment, a control valve corresponding to each spray assembly is added to the water vapor generating device, and after adjusting the working frequency of the water pump, the pressure difference between the water inlet pipe and the water vapor chamber of the tank body is obtained. If the pressure difference is not within the preset pressure difference range, then the target control valve is determined from the control valves corresponding to each spray assembly. The target control valve is further controlled to adjust the working state of the spray assembly corresponding to the target control valve so that the pressure difference between the water inlet pipe and the water vapor chamber of the tank body enters the preset pressure difference range. The pressure difference between the water inlet pipe and the water vapor chamber of the tank body will affect the spray effect of the spray assembly. Therefore, when the pressure difference is within the preset pressure difference range, the spray effect of the spray assembly can be maintained stable, and the linearity between the water vapor preparation amount and the working frequency of the water pump is improved, thereby improving the accuracy of controlling the water vapor preparation amount.

[0068] See also Figure 8 , provides a flow chart of determining and closing a target control valve in an embodiment of the present application, such as Figure 8 As shown, the method of the embodiment of the present application may include the following steps S201-S203.

[0069] S201, if the pressure difference between the water inlet pipe and the water vapor chamber of the tank body is less than the lower limit of the preset pressure difference range, determine the control valve in the open state from the control valves corresponding to each spray assembly;

[0070] S202, determining a target control valve from the control valves in an open state.

[0071] S203, closing the target control valve to adjust the working state of the spray assembly corresponding to the target control valve to a closed state, so that the pressure difference between the water inlet pipe and the water vapor chamber of the tank body falls within a preset pressure difference range.

[0072] Specifically, if the pressure difference between the water inlet pipe and the water vapor chamber of the tank body is less than the preset pressure difference range, it means that the pressure difference between the water inlet pipe and the water vapor chamber of the tank body is too low, which may cause the spray particle size of the spray assembly to increase, thereby affecting the amount of water vapor prepared. In this case, it is necessary to screen out the control valves in the open state from the control valves corresponding to all spray assemblies. It is understandable that when the control valve is in the open state, the corresponding spray assembly is in the open state, which plays a role in dividing the pressure of the water inlet pipe. It should be noted that the number of control valves in the open state is generally multiple.

[0073] Among the multiple control valves that have been determined to be in the open state, some of the control valves that are in the open state are determined to be the target control valves. Furthermore, closing the target control valve changes the working state of the spray assembly corresponding to the target control valve, turning it from the open state to the closed state, and the effect on the partial pressure of the water inlet pipe disappears. Due to the closure of the spray assembly, the pressure value of the water inlet pipe will increase accordingly, which will help to increase the pressure difference between the water inlet pipe and the water vapor chamber of the tank body, so that the pressure difference between the water inlet pipe and the water vapor chamber of the tank body returns to the preset pressure difference range, so as to maintain the stable spraying effect of the spray assembly.

[0074] In some cases, the target control valve can be controlled to make the pressure difference between the water inlet pipe and the water vapor chamber of the tank body fall within the preset pressure difference range. In some cases, if the target control valve cannot be controlled to make the pressure difference between the water inlet pipe and the water vapor chamber of the tank body fall within the preset pressure difference range, then steps S201-S203 can be repeatedly performed until the pressure difference between the water inlet pipe and the water vapor chamber of the tank body falls within the preset pressure difference range.

[0075] In this embodiment, by real-time monitoring of the pressure difference between the water inlet pipe and the water vapor chamber of the tank, and when it is less than the lower limit of the preset pressure difference range, the partial control valve in the open state, i.e., the target control valve, is determined and closed to adjust the working state of the corresponding spray component. This process effectively improves the response speed and adjustment accuracy of the water vapor generating device to the pressure difference, ensures the stability of the spray effect of the spray component, and avoids the problem of increased spray particle size due to too low pressure difference. It can effectively improve the linearity between the water vapor preparation amount and the working frequency of the water pump, thereby improving the accuracy of controlling the water vapor preparation amount.

[0076] See also Fig. 9 , provides a schematic diagram of a process for determining and opening a target control valve in an embodiment of the present application, such as Fig. 9 As shown, the method of the embodiment of the present application may include the following steps S301-S303.

[0077] S301, if the pressure difference between the water inlet pipe and the water vapor chamber of the tank body is greater than the upper limit of the preset pressure difference range, determine the control valve in the closed state from the control valves corresponding to each spray assembly;

[0078] S302, determining a target control valve from the control valves in a closed state.

[0079] S303, opening the target control valve to adjust the working state of the spray assembly corresponding to the target control valve to an open state, so that the pressure difference between the water inlet pipe and the water vapor chamber of the tank body falls within a preset pressure difference range.

[0080] Specifically, if the pressure difference between the water inlet pipe and the water vapor chamber of the tank body is greater than the preset pressure difference range, it means that the pressure difference between the water inlet pipe and the water vapor chamber of the tank body is too high, which may cause the spray particle size of the spray assembly to decrease, thereby affecting the amount of water vapor prepared. In this case, it is necessary to screen out the control valves in the closed state from the control valves corresponding to all spray assemblies. It is understandable that when the control valve is in the closed state, the corresponding spray assembly is in the closed state, and the effect of partial pressure on the water inlet pipe disappears. It should be noted that the number of control valves in the closed state is generally multiple.

[0081] Among the multiple control valves that have been determined to be in a closed state, some of the control valves that are in a closed state are determined to be target control valves. Further, the target control valve is opened. This action changes the working state of the spray assembly corresponding to the target control valve, turning it from a closed state to an open state, which plays a role in dividing the pressure of the water inlet pipe. Due to the opening of the spray assembly, the pressure value of the water inlet pipe will be reduced accordingly, which helps to reduce the pressure difference between the water inlet pipe and the water vapor chamber of the tank body, so that the pressure difference between the water inlet pipe and the water vapor chamber of the tank body returns to the preset pressure difference range, so as to maintain the stable spraying effect of the spray assembly.

[0082] In some cases, the target control valve can be controlled to make the pressure difference between the water inlet pipe and the water vapor chamber of the tank body fall within the preset pressure difference range. In some cases, if the target control valve cannot be controlled to make the pressure difference between the water inlet pipe and the water vapor chamber of the tank body fall within the preset pressure difference range, then steps S301-S303 can be repeatedly performed until the pressure difference between the water inlet pipe and the water vapor chamber of the tank body falls within the preset pressure difference range.

[0083] In this embodiment, by real-time monitoring of the pressure difference between the water inlet pipe and the water vapor chamber of the tank, and when it is greater than the upper limit of the preset pressure difference range, the partial control valve in the closed state, i.e., the target control valve, is determined and opened to adjust the working state of the corresponding spray component. This process effectively improves the response speed and adjustment accuracy of the water vapor generating device to the pressure difference, ensures the stability of the spray effect of the spray component, and avoids the problem of too small spray particle size caused by excessive pressure difference. It can effectively improve the linearity between the water vapor preparation amount and the working frequency of the water pump, thereby improving the accuracy of controlling the water vapor preparation amount.

[0084] See also Fig.10 , provides a schematic diagram of a process for obtaining a pressure difference value for an embodiment of the present application. The water vapor generating device further includes a first pressure sensor in the water inlet pipe and a second pressure sensor in the water vapor chamber of the tank body. Fig.10 As shown, the method of the embodiment of the present application may include the following steps S401-S402.

[0085] S401, after adjusting the working frequency of the water pump, obtaining a pressure value of the water inlet pipe collected by the first pressure sensor and a pressure value of the water vapor chamber of the tank body collected by the second pressure sensor;

[0086] S402, determining the pressure difference between the water inlet pipe and the water vapor chamber of the tank body according to the pressure value of the water inlet pipe and the pressure value of the water vapor chamber of the tank body.

[0087] Specifically, the water pump is the power source in the water vapor generating device, and the change of its operating frequency will directly affect the pressure state of the water inlet pipe. Therefore, every time the operating frequency of the water pump is adjusted, the first pressure sensor and the second pressure sensor will be immediately triggered to collect the pressure value. The first pressure sensor will capture the pressure value in the water inlet pipe, which reflects the direct impact of the adjustment of the operating frequency of the water pump on the pressure of the water inlet pipe. At the same time, the second pressure sensor also synchronously records the pressure value in the water vapor chamber of the tank body, which reflects the pressure state formed in the water vapor chamber of the tank body due to the generation and flow of water vapor.

[0088] Next, the pressure value of the water inlet pipe collected by the first pressure sensor and the pressure value of the water vapor chamber of the tank body collected by the second pressure sensor are differenced to obtain the pressure difference between the water inlet pipe and the water vapor chamber of the tank body.

[0089] To understand this process more intuitively, here is a calculation example:

[0090] Assuming that the pressure value of the water inlet pipe collected by the first pressure sensor is P1, and the pressure value of the water vapor chamber of the tank body collected by the second pressure sensor is P2, the pressure difference ΔP between the water inlet pipe and the water vapor chamber of the tank body can be calculated by the following formula:

[0091] ΔP=P1-P2

[0092] In this embodiment, by adding a first pressure sensor and a second pressure sensor to the water vapor generating device, the pressure value monitoring of the water inlet pipe and the water vapor chamber of the tank body is realized. After each adjustment of the working frequency of the water pump, the pressure data of the two sensors are obtained, and the difference operation is performed to quickly determine the pressure difference between the water inlet pipe and the water vapor chamber of the tank body, which helps to timely capture the impact of the adjustment of the working frequency of the water pump on the pressure state of the water vapor generating device, and provides a data basis for the subsequent control of the control valve.

[0093] See also Fig.11 , a schematic diagram of a flow chart for adjusting the operating frequency of a water pump is provided for an embodiment of the present application, such as Fig.11 As shown, the method of the embodiment of the present application may include the following steps S501-S503.

[0094] S501, obtaining the pressure value of the water vapor chamber of the tank;

[0095] S502, if the pressure value of the water vapor chamber of the tank body is greater than a preset first pressure value, reducing the operating frequency of the water pump;

[0096] S503, if the pressure value of the water vapor chamber of the tank body is less than a preset second pressure value, increasing the working frequency of the water pump, wherein the preset first pressure value is greater than the preset second pressure value.

[0097] Specifically, the water vapor generating device collects the pressure value of the water vapor chamber of the tank body through the second pressure sensor in the water vapor chamber of the tank body. It can be understood that when the demand side load decreases, the demand for water vapor decreases, and the water vapor generating device monitors that the pressure value of the water vapor chamber of the tank body increases; when the demand side load increases, the demand for water vapor increases, and the water vapor generating device monitors that the pressure value of the water vapor chamber of the tank body decreases.

[0098] In order to balance the supply and demand relationship and improve the economic efficiency of the water vapor generating equipment, it is generally required that the pressure value of the water vapor chamber be maintained within a certain range. To this end, it is necessary to compare the pressure value of the water vapor chamber of the tank body with the preset first pressure value and the preset second pressure value, respectively, wherein the preset first pressure value is greater than the preset second pressure value.

[0099] If the pressure value of the water vapor chamber of the tank body is greater than the preset first pressure value, it means that the amount of water vapor prepared exceeds the actual demand on the demand side, or the consumption on the demand side is reduced, resulting in water vapor accumulation in the water vapor chamber of the tank body, thereby increasing the pressure. Accordingly, the operating frequency of the water pump can be reduced. By reducing the operating frequency of the water pump, the water flow velocity in the water inlet pipe is reduced, and the spray intensity of the spray assembly is reduced, the amount of water vapor prepared is reduced, and the pressure value of the water vapor chamber of the tank body is gradually reduced to below the preset first pressure value.

[0100] If the pressure value of the water vapor chamber of the tank is less than the preset second pressure value, it means that the amount of water vapor prepared is insufficient to meet the actual demand on the demand side, or the consumption on the demand side increases, resulting in insufficient water vapor in the water vapor chamber of the tank, thereby reducing the pressure. In order to make up for the gap between supply and demand, the operating frequency of the water pump can be increased. By increasing the operating frequency of the water pump, the water flow velocity in the water inlet pipe is increased, and the spray intensity of the spray component is increased, the amount of water vapor prepared is increased, and the pressure value of the water vapor chamber of the tank is gradually increased to above the preset second pressure value.

[0101] It is worth noting that the preset first pressure value and the preset second pressure value are two key thresholds set according to the actual operation and control requirements of the water vapor generating device. They represent the upper and lower pressure limits of the water vapor chamber of the tank, respectively, and are the basis for judging whether the working frequency of the water pump needs to be adjusted. The preset first pressure value is greater than the preset second pressure value, ensuring that when the internal pressure of the tank is too high or too low, the corresponding adjustment mechanism can be triggered in time to maintain the stable operation of the water vapor generating device.

[0102] For example, assuming that at a certain moment, the pressure value P1 of the water vapor chamber of the tank body is greater than the preset first pressure value P_max, then according to the logic of step S502, the operating frequency of the water pump is automatically reduced by n Hz to reduce the amount of water vapor prepared, so that the pressure inside the tank body is gradually reduced to a reasonable range. On the contrary, if the pressure value P1 of the water vapor chamber of the tank body is less than the preset second pressure value P_min, then according to the logic of step S503, the operating frequency of the water pump is automatically increased by m Hz to increase the amount of water vapor prepared, so that the pressure inside the tank body is gradually increased to a reasonable range. Through such a dynamic adjustment mechanism, the water vapor generating device can always maintain an efficient and stable operating state.

[0103] In this embodiment, by monitoring the pressure value of the water vapor chamber of the tank body in real time and dynamically adjusting the operating frequency of the water pump based on the comparison result with the preset first pressure value and the preset second pressure value, intelligent control of the water vapor generating equipment is achieved, the supply and demand of water vapor is effectively balanced, and the economy of the water vapor generating equipment is improved.

[0104] See also Fig.12 , Fig.12 It is a schematic diagram of a comprehensive control flow of a water vapor generating device provided in an embodiment of the present application.

[0105] First, the water vapor generating device includes a first pressure sensor in the water inlet pipe and a second pressure sensor in the water vapor chamber of the tank body. The first pressure sensor continuously collects the pressure value P1 of the water inlet pipe, and the second pressure sensor continuously collects the pressure value P2 of the water vapor chamber of the tank body.

[0106] The preset pressure value range is a numerical range set according to the actual operation of the water vapor generating device and the control requirements, the upper limit of the preset pressure value range is the preset first pressure value P_max, and the lower limit of the preset pressure value range is the preset second pressure value P_min. The pressure value P2 of the water vapor chamber of the tank body is obtained, and the pressure value P2 of the water vapor chamber of the tank body is compared with the preset first pressure value P_max and the preset second pressure value P_min respectively.

[0107] If the pressure value P2 of the water vapor chamber of the tank body is not greater than the preset first pressure value P_max and not less than the preset second pressure value P_min, it indicates that the pressure value of the water vapor chamber of the tank body is appropriate and there is no need to adjust the working frequency of the water pump.

[0108] If the pressure value P2 of the water vapor chamber of the tank is greater than the preset first pressure value P_max, it means that the amount of water vapor prepared exceeds the actual demand on the demand side, or the consumption on the demand side is reduced, resulting in water vapor accumulation in the water vapor chamber of the tank, thereby increasing the pressure. Accordingly, the operating frequency n Hz of the water pump can be reduced. By reducing the operating frequency of the water pump, the water flow velocity in the water inlet pipe is reduced, and the spray intensity of the spray component is reduced, the amount of water vapor prepared is reduced, and the pressure value P2 of the water vapor chamber of the tank is gradually reduced to below the preset first pressure value P_max.

[0109] After the operating frequency of the water pump is reduced to n Hz, the first pressure sensor and the second pressure sensor will be triggered to collect the pressure value. The first pressure sensor will capture the pressure value P1 in the water inlet pipe. At the same time, the second pressure sensor will also synchronously record the pressure value P2 in the water vapor chamber of the tank.

[0110] Using the pressure value P1 of the water inlet pipe and the pressure value P2 of the water vapor chamber of the tank, the pressure difference ΔP between the water inlet pipe and the water vapor chamber of the tank can be calculated by the following formula:

[0111] ΔP=P1-P2

[0112] Further, the pressure difference ΔP between the water inlet pipe and the water vapor chamber of the tank body is compared with a preset pressure difference range, the upper limit of the preset pressure difference range is ΔP_max, and the lower limit of the preset pressure difference range is ΔP_min.

[0113] Generally speaking, reducing the operating frequency of the water pump n Hz will cause the pressure difference ΔP between the water inlet pipe and the water vapor chamber of the tank body to become smaller. If the pressure difference ΔP between the water inlet pipe and the water vapor chamber of the tank body is less than the lower limit ΔP_min of the preset pressure difference range, it means that the front and rear pressure difference of the spray assembly is not enough to maintain the expected spray effect. At this time, it is necessary to determine the target control valve from the control valves in the open state, and then close the target control valve so that the partial pressure effect of a part of the spray assembly disappears, and the pressure difference ΔP between the water inlet pipe and the water vapor chamber of the tank body will increase accordingly. This process may be performed once or repeatedly until the pressure difference ΔP between the water inlet pipe and the water vapor chamber of the tank body is not less than the lower limit ΔP_min of the preset pressure difference range. Then, the remaining part of the spray assembly in the open state can obtain sufficient front and rear pressure difference to achieve the expected spray effect.

[0114] If the pressure value P2 of the water vapor chamber of the tank body is less than the preset second pressure value P_min, it means that the water vapor preparation amount does not meet the actual demand of the demand side, or the consumption on the demand side increases, resulting in excessive consumption of water vapor in the water vapor chamber of the tank body, thereby reducing the pressure. Accordingly, the operating frequency n Hz of the water pump can be increased. By increasing the operating frequency of the water pump, the water flow speed in the water inlet pipe is accelerated, and the spray intensity of the spray component is increased, the water vapor preparation amount is increased, and the pressure value P2 of the water vapor chamber of the tank body is gradually increased to above the preset second pressure value P_min.

[0115] After the operating frequency of the water pump is increased to n Hz, the first pressure sensor and the second pressure sensor will be triggered to collect the pressure value. The first pressure sensor will capture the pressure value P1 in the water inlet pipe. At the same time, the second pressure sensor will also synchronously record the pressure value P2 in the water vapor chamber of the tank.

[0116] Using the pressure value P1 of the water inlet pipe and the pressure value P2 of the water vapor chamber of the tank, the pressure difference ΔP between the water inlet pipe and the water vapor chamber of the tank can be calculated by the following formula:

[0117] ΔP=P1-P2

[0118] Furthermore, the pressure difference ΔP between the water inlet pipe and the water vapor chamber of the tank body is compared with a preset pressure difference range.

[0119] Generally speaking, increasing the operating frequency of the water pump n Hz will cause the pressure difference ΔP between the water inlet pipe and the water vapor chamber of the tank to increase. If the pressure difference ΔP between the water inlet pipe and the water vapor chamber of the tank is greater than the upper limit ΔP_max of the preset pressure difference range, it means that the front and rear pressure difference of the spray assembly is not enough to maintain the expected spray effect. At this time, it is necessary to determine the target control valve from the control valves in the closed state, and then open the target control valve so that a part of the spray assembly plays a pressure-dividing role, and the pressure difference ΔP between the water inlet pipe and the water vapor chamber of the tank will be reduced accordingly. This process may be performed once or repeatedly until the pressure difference ΔP between the water inlet pipe and the water vapor chamber of the tank is not greater than the upper limit ΔP_max of the preset pressure difference range. Then, the spray assembly in the open state can obtain sufficient front and rear pressure difference to achieve the expected spray effect.

[0120] To further demonstrate the control effect of this embodiment, see Fig.13 and Fig.14 .

[0121] like Fig.13As shown, the vertical axis P represents the pressure value of the water inlet pipe, and the horizontal axis Q represents the water flow rate of the water inlet pipe. In the case where the control valve is not set or the control valve is not controlled, the first characteristic curve formed by the pressure value of the water inlet pipe and the water flow rate of the water inlet pipe remains unchanged. If the working frequency of the water pump is reduced so that the water flow rate Q2 of the water inlet pipe drops to the water flow rate Q1 of the water inlet pipe, then the pressure value P1 of the water inlet pipe will also drop to the pressure value P2 of the water inlet pipe accordingly. As the pressure value of the water inlet pipe drops, it is difficult for the spray assembly to maintain the expected front-to-back pressure difference, resulting in unstable spraying effect of the spray assembly, and it is also difficult to accurately control the amount of water vapor preparation.

[0122] like Fig.14 As shown, the vertical axis P represents the pressure value of the water inlet pipe, and the horizontal axis Q represents the water flow rate of the water inlet pipe. After applying the solution of the embodiment of the present application, the control valve can be controlled, thereby changing the characteristic curve of the water inlet pipe.

[0123] Assume that before some control valves are closed, the characteristic curve of the water inlet pipe is the second characteristic curve. If the working frequency of the water pump is reduced so that the water flow rate Q2 of the water inlet pipe drops to the water flow rate Q1 of the water inlet pipe, then the pressure value P1 of the water inlet pipe will also drop to the pressure value P2 of the water inlet pipe accordingly, and the water inlet pipe will switch from the operating state point N1 to the operating state point N2. As the pressure value of the water inlet pipe drops, it is difficult for the spray component to maintain the expected front and rear pressure difference, resulting in unstable spraying effect of the spray component, and it is difficult to accurately control the amount of water vapor preparation.

[0124] After closing some control valves, the characteristic curve of the water inlet pipe is the third characteristic curve. If the working frequency of the water pump is reduced so that the water flow rate Q2 of the water inlet pipe drops to the water flow rate Q1 of the water inlet pipe, the pressure value P1 of the water inlet pipe can still be maintained, and the water inlet pipe switches from the operating state point N1 to the operating state point N3. As the pressure value of the water inlet pipe decreases, the spray component can still maintain the expected front and rear pressure difference, so that the spray effect of the spray component is stable and the amount of water vapor preparation can be accurately controlled.

[0125] In this embodiment, a control valve corresponding to each spray assembly is added to the water vapor generating device, and after adjusting the working frequency of the water pump, the pressure difference between the water inlet pipe and the water vapor chamber of the tank body is obtained. If the pressure difference is not within the preset pressure difference range, then the target control valve is determined from the control valves corresponding to each spray assembly. The target control valve is further controlled to adjust the working state of the spray assembly corresponding to the target control valve so that the pressure difference between the water inlet pipe and the water vapor chamber of the tank body enters the preset pressure difference range. The pressure difference between the water inlet pipe and the water vapor chamber of the tank body will affect the spray effect of the spray assembly. Therefore, when the pressure difference is within the preset pressure difference range, the spray effect of the spray assembly can be maintained stable, and the linearity between the water vapor preparation amount and the working frequency of the water pump is improved, thereby improving the accuracy of controlling the water vapor preparation amount.

[0126] Based on the above Figure 1 The scene shows Figure 2 - Figure 6 The structure of the water vapor generating device will be combined with Fig.15 The steam generating device provided in the embodiment of the present application is introduced in detail. It should be noted that: Fig.15 The steam generating device 2000 is used to perform the present application Figure 7 - Fig.14 For the convenience of explanation, only the part related to the embodiment of the present application is shown. For the specific technical details not disclosed, please refer to the present application. Figure 7 - Fig.14 Specifically, the water vapor generating device 2000 may include a memory 2910, a processor 2920, a tank body 2100, a water pump 2200, a water inlet pipe 2300, a plurality of spray assemblies 2400, and a control valve 2500 corresponding to each of the plurality of spray assemblies 2400, the water pump 2200 is connected to the water inlet pipe 2300, and the water inlet pipe 2300 is connected to the water vapor chamber 2110 of the tank body 2100 through the plurality of spray assemblies 2400;

[0127] The processor 2920 is electrically connected to the memory 2910 .

[0128] The processor 2920 is the control center of the water vapor generating device 2000, and may include one or more processing cores. The processor 2920 uses various interfaces and lines to connect the various parts of the entire water vapor generating device 2000, and executes various functions and processes data of the water vapor generating device 2000 by running or calling the computer program stored in the memory 2910, and calling the data stored in the memory 2910, so as to control the water vapor generating device 2000 as a whole. Optionally, the processor 2920 can be implemented in at least one hardware form of digital signal processing (DSP), field programmable gate array (FPGA), and programmable logic array (PLA). The processor 2920 can integrate one or more combinations of CPU, image processor 2920 (GPU) and modem. Among them, the CPU mainly processes the operating system, user pages and applications, etc.; the GPU is responsible for rendering and drawing the display content; the modem is used to handle wireless communication. It is understandable that the above-mentioned modem may not be integrated into the processor 2920, but may be implemented separately through a communication chip.

[0129] The memory 2910 can be used to store software programs and modules, and the processor 2920 executes various functional applications and data processing by running the computer programs and modules stored in the memory 2910. The memory 2910 can mainly include a program storage area and a data storage area, wherein the program storage area can store an operating system, a computer program required for at least one function, etc.; the data storage area can store data created according to the use of the water vapor generating device 2000, etc.

[0130] In addition, the memory 2910 may include a high-speed random access memory 2910, and may also include a non-volatile memory 2910, such as at least one disk memory 2910, a flash memory device, or other volatile solid-state memory 2910. Accordingly, the memory 2910 may also include a memory 2910 controller to provide the processor 2920 with access to the memory 2910.

[0131] In this embodiment, the processor 2920 in the water vapor generating device 2000 loads instructions corresponding to the processes of one or more computer programs into the memory 2910 according to the following steps, and the processor 2920 runs the computer program stored in the memory 2910 to implement various functions, as follows:

[0132] After adjusting the working frequency of the water pump, the pressure difference between the water inlet pipe and the water vapor chamber of the tank is obtained;

[0133] If the pressure difference between the water inlet pipe and the water vapor chamber of the tank body is not within the preset pressure difference range, a target control valve is determined from the control valves corresponding to each spray assembly;

[0134] The target control valve is controlled to adjust the working state of the spray assembly corresponding to the target control valve so that the pressure difference between the water inlet pipe and the water vapor chamber of the tank body falls within the preset pressure difference range.

[0135] Optionally, when the processor 2920 determines the target control valve from the control valves corresponding to each spray component if the pressure difference between the water inlet pipe and the water vapor chamber of the tank body is not within a preset pressure difference range, the processor 2920 specifically executes: if the pressure difference between the water inlet pipe and the water vapor chamber of the tank body is less than the lower limit of the preset pressure difference range, determining the control valve in the open state from the control valves corresponding to each spray component; and determining the target control valve from the control valves in the open state.

[0136] Optionally, when the processor 2920 controls the target control valve to adjust the working state of the spray assembly corresponding to the target control valve so that the pressure difference between the water inlet pipe and the water vapor chamber of the tank body falls within a preset pressure difference range, it specifically executes: closing the target control valve to adjust the working state of the spray assembly corresponding to the target control valve to a closed state so that the pressure difference between the water inlet pipe and the water vapor chamber of the tank body falls within a preset pressure difference range.

[0137] Optionally, when the processor 2920 determines the target control valve from the control valves corresponding to each spray component if the pressure difference between the water inlet pipe and the water vapor chamber of the tank body is not within the preset pressure difference range, the processor 2920 specifically executes: if the pressure difference between the water inlet pipe and the water vapor chamber of the tank body is greater than the upper limit of the preset pressure difference range, then determine the control valve in the closed state from the control valves corresponding to each spray component; and determine the target control valve from the control valves in the closed state.

[0138] Optionally, when the processor 2920 controls the target control valve to adjust the working state of the spray assembly corresponding to the target control valve so that the pressure difference between the water inlet pipe and the water vapor chamber of the tank body falls within a preset pressure difference range, it specifically executes: opening the target control valve to adjust the working state of the spray assembly corresponding to the target control valve to an open state so that the pressure difference between the water inlet pipe and the water vapor chamber of the tank body falls within a preset pressure difference range.

[0139] Optionally, the water vapor generating device also includes a first pressure sensor in the water inlet pipe and a second pressure sensor in the water vapor chamber of the tank body; when the processor 2920 executes to obtain the pressure difference between the water inlet pipe and the water vapor chamber of the tank body, it specifically performs: after adjusting the working frequency of the water pump, obtain the pressure value of the water inlet pipe collected by the first pressure sensor and the pressure value of the water vapor chamber of the tank body collected by the second pressure sensor; determine the pressure difference between the water inlet pipe and the water vapor chamber of the tank body according to the pressure value of the water inlet pipe and the pressure value of the water vapor chamber of the tank body.

[0140] Optionally, before executing the acquisition of the pressure difference between the water inlet pipe and the containing cavity of the tank body, the processor 2920 specifically executes the following: acquiring the pressure value of the water vapor cavity of the tank body; if the pressure value of the water vapor cavity of the tank body is greater than a preset first pressure value, reducing the operating frequency of the water pump; if the pressure value of the water vapor cavity of the tank body is less than a preset second pressure value, increasing the operating frequency of the water pump, wherein the preset first pressure value is greater than the preset second pressure value.

[0141] In one embodiment, the water inlet pipe includes a first water inlet pipe, a second water inlet pipe and a third water inlet pipe, and the control valve includes a first control valve arranged on the first water inlet pipe and a second control valve arranged on the third water inlet pipe; the water outlet end of the first water inlet pipe is respectively connected to the water inlet ends of the second water inlet pipe and the third water inlet pipe; the water pump is arranged at the water inlet end of the first water inlet pipe; each spray assembly is arranged at the water outlet end of a second water inlet pipe or the water outlet end of a third water inlet pipe.

[0142] For example, see Figure 3 The water pump 2200 is disposed at the water inlet end of the first water inlet pipe 2310, and the first water inlet pipe 2310 is provided with a corresponding first control valve 2510. If the first control valve 2510 is in an open state, the high-temperature water pumped by the water pump 2200 will enter the first water inlet pipe 2310 through the first control valve 2510.

[0143] In addition, the water outlet of the first water inlet pipe 2310 is directly connected to the water inlet of the second water inlet pipe 2320, and the second water inlet pipe 2320 is not provided with a corresponding control valve 2500. Therefore, the high-temperature water in the first water inlet pipe 2310 can enter the second water inlet pipe 2320 without hindrance, and it can be seen that the opening or closing of the first control valve 2510 will directly affect the working state of all the spray assemblies 2400 arranged in the second water inlet pipe 2320, that is, the control valve 2500 corresponding to the spray assembly 2400 arranged in the second water inlet pipe 2320 is the first control valve 2510.

[0144] In addition, the water outlet of the first water inlet pipe 2310 is respectively connected to the water inlet of the plurality of third water inlet pipes 2330, and each third water inlet pipe 2330 is provided with a corresponding second control valve 2520. Then, whether the high-temperature water in the first water inlet pipe 2310 can enter the third water inlet pipe 2330 depends on the state of the second control valve 2520. It can be seen that for the spray assembly 2400 of a certain third water inlet pipe 2330, the first control valve 2510 and the second control valve 2520 of the third water inlet pipe 2330 jointly affect the working state of all the spray assemblies 2400 arranged in the third water inlet pipe 2330, that is, the control valve 2500 corresponding to the spray assembly 2400 arranged in the third water inlet pipe 2330 is the first control valve 2510 and the second control valve 2520 of the third water inlet pipe 2330.

[0145] In this embodiment, the first water inlet pipe 2310 serves as the main water inlet pipe, and the first control valve 2510 thereon can globally control the high-temperature water extracted by the water pump 2200 to enter the second water inlet pipe 2320 and all the third water inlet pipes 2330, thereby directly affecting the working state of all the spray assemblies 2400 on the second water inlet pipe 2320. At the same time, the second control valve 2520 independently set on each third water inlet pipe 2330 provides a refined control capability for the spray assemblies 2400 on their respective pipelines. This hierarchical control strategy can accurately adjust the working state of each spray assembly 2400 according to actual needs, thereby improving the control flexibility of the water vapor generating device 2000.

[0146] In one embodiment, the water inlet pipe includes a first water inlet pipe and multiple third water inlet pipes, the control valve includes a first control valve arranged on the first water inlet pipe and a second control valve arranged on the first water inlet pipe; the water outlet end of the first water inlet pipe is respectively connected to the water inlet ends of the multiple third water inlet pipes; the water pump is arranged at the water inlet end of the first water inlet pipe; and each spray assembly is arranged at the water outlet end of a third water inlet pipe.

[0147] For example, see Figure 4The water pump 2200 is disposed at the water inlet end of the first water inlet pipe 2310, and the water outlet end of the first water inlet pipe 2310 is respectively connected to the water inlet ends of a plurality of third water inlet pipes 2330, and each third water inlet pipe 2330 is provided with a corresponding second control valve 2520. Then, the water pump 2200 can directly pump the high-temperature water to the first water inlet pipe 2310, and whether the high-temperature water in the first water inlet pipe 2310 can enter the third water inlet pipe 2330 depends on the state of the second control valve 2520. It can be seen that, for a spray assembly 2400 of a certain third water inlet pipe 2330, the first control valve 2510 and the second control valve 2520 of the third water inlet pipe 2330 jointly affect the working status of all spray assemblies 2400 arranged on the third water inlet pipe 2330, that is, the control valve 2500 corresponding to the spray assembly 2400 arranged on the third water inlet pipe 2330 is the second control valve 2520 of the third water inlet pipe 2330.

[0148] In this embodiment, the first water inlet pipe 2310 serves as a water inlet main pipe, which directly delivers the high-temperature water extracted by the water pump 2200 to each third water inlet pipe 2330. At the same time, the second control valve 2520 independently provided on each third water inlet pipe 2330 allows independent control of the spray assembly 2400 on each third water inlet pipe 2330. This structure can support accurate adjustment of the working state of each spray assembly 2400 according to actual needs, thereby improving the control flexibility of the water vapor generating device 2000.

[0149] In one embodiment, the water inlet pipe includes a first water inlet pipe and multiple second water inlet pipes, and the control valve includes a third control valve arranged on the spray assembly; the water outlet end of the first water inlet pipe is respectively connected to the water inlet ends of the multiple second water inlet pipes; the water pump is arranged at the water inlet end of the first water inlet pipe; and each spray assembly is arranged at the water outlet end of a second water inlet pipe.

[0150] For example, see Figure 5 The water pump 2200 is arranged at the water inlet end of the first water inlet pipe 2310, and the water outlet ends of the first water inlet pipe 2310 are respectively connected to the water inlet ends of multiple second water inlet pipes 2320. No corresponding control valves are arranged in the first water inlet pipe 2310 and the second water inlet pipe 2320, that is, the high-temperature hot water pumped by the water pump 2200 can directly enter the first water inlet pipe 2310 and the second water inlet pipe 2320.

[0151] Each spray component 2400 is provided with a corresponding third control valve, that is, for any spray component 2400, if the third control valve corresponding to the spray component 2400 is opened, the spray component 2400 can be put into an open state; if the third control valve corresponding to the spray component 2400 is closed, the spray component 2400 can be put into a closed state.

[0152] In this embodiment, since no control valve is provided in the first water inlet pipe 2310 and the second water inlet pipe 2320, the high-temperature hot water pumped by the water pump 2200 can flow from the first water inlet pipe 2310 into the second water inlet pipe 2320 without hindrance. At the same time, each spray assembly 2400 is equipped with an independent third control valve, which realizes direct control of the working state of each spray assembly 2400, and improves the accuracy and flexibility of control.

[0153] In one embodiment, the tank body includes a gas-liquid separation structure, which divides the tank body's containing cavity into a water vapor cavity and a liquid cavity; the water vapor generating device also includes a first pressure sensor in the water inlet pipe and a second pressure sensor in the water vapor cavity of the tank body.

[0154] For example, see Figure 2 and Figure 3 In order to monitor the pressure difference between the water inlet pipe 2300 and the water vapor chamber 2110 of the tank body 2100, a first pressure sensor 2610 is provided at the first water inlet pipe 2310 of the water vapor generating device 2000, and a second pressure sensor 2620 is provided in the water vapor receiving chamber of the tank body 2100. The first water inlet pipe 2310 is the main water inlet pipe in the water inlet pipe 2300 of the water vapor generating device 2000, and the water inlet pipe 2300 also includes Figure 2 The first pressure sensor 2610 is arranged on the first water inlet pipe 2310, so that the pressure value can be accurately collected to represent the pressure of the entire water inlet pipe 2300. Similarly, the first pressure sensor 2610 can also be arranged on the water inlet pipe, such as Figure 3 The second water inlet pipe 2320 is a water inlet branch pipe, and the second water inlet pipe 2320 is directly connected to the first water inlet pipe 2310. The first pressure sensor 2610 is arranged on the second water inlet pipe 2320 and can also accurately collect the pressure value to characterize the pressure of the entire water inlet pipe 2300.

[0155] For example, see Figure 2 The gas-liquid separation structure 2800 divides the containing cavity of the tank body 2100 into a water vapor cavity 2110 and a liquid cavity 2120. Specifically, the gas-liquid separation structure 2800 can be an interception wire mesh. The mesh size of the interception wire mesh is configured to allow water vapor to pass freely while blocking larger droplets. Due to their smaller volume and weight, water vapor molecules can easily penetrate the mesh of the interception wire mesh and enter the water vapor cavity 2110, while the droplets will be blocked when they hit the interception wire mesh due to their larger surface tension and volume and flow back to the liquid cavity 2120 along the surface of the interception wire mesh.

[0156] In this embodiment, the performance and reliability of the water vapor generating device 2000 are significantly improved by introducing the gas-liquid separation structure 2800 and the dual pressure sensor configuration. The gas-liquid separation structure 2800 effectively separates the containing cavity of the tank body 2100 into a water vapor cavity 2110 and a liquid cavity 2120, ensuring the purity and fluidity of the water vapor, while avoiding the pressure and temperature fluctuations that may be caused by droplets entering the water vapor cavity 2110. The setting of the dual pressure sensor realizes the real-time monitoring of the pressure difference between the water inlet pipe 2300 and the water vapor cavity 2110 of the tank body 2100, providing key data support for the precise control of the water vapor preparation process.
