[0049] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0050] The control method of the water system of the water purifier provided in the embodiment of the present application can be applied to the water purifier. As shown in FIG1 , the water system of the water purifier includes a purification device 110, a pressure detection component 120, a flow regulating device 130, a water outlet device 140 and a control module. The water inlet end of the purification device 110 is used to access raw water, and the purification device 110 is used to purify the accessed raw water to produce pure water.

[0051] The water outlet of the purification device 110 is connected to the water outlet device 140 through the flow regulating device 130, and the water outlet device 140 provides the required hot water or normal temperature water to the user. In one embodiment, as shown in FIG2 , the water outlet device 140 may include a hot water branch 141, a normal temperature water branch 142, and a water outlet assembly 143. The water inlet of the hot water branch 141 is connected to the first water outlet A of the flow regulating device 130, the normal temperature water branch 142 is connected to the second water outlet B of the flow regulating device 130, and the water outlets of the hot water branch 141 and the normal temperature water branch 142 are both connected to the water outlet assembly 143. The structure of the water outlet assembly 143 can be set in combination with actual conditions, for example, including a water outlet nozzle, and the hot water branch 141 and the normal temperature water branch 142 are both connected to the water outlet nozzle.

[0052] When a user uses the water purifier to take water, the raw water first enters the purification device 110 for purification. The pure water obtained by the purification device 110 can be divided into two paths after passing through the flow regulating device 130. One path passes through the first water outlet A and enters the hot water branch 141 for heating. The heated water flows to the water outlet component 143 and is output as hot water. The other path passes through the second water outlet B, passes through the normal temperature water branch 142 and flows to the water outlet component 143 and is output as normal temperature water.

[0053] The flow regulating device 130 is used to regulate the flow of pure water flowing into the hot water branch 141 or the normal temperature water branch 142 to meet the user's water output and water temperature requirements.

[0054] The pressure detection component 120 is disposed between the purification device 110 and the flow regulating device 130. The control module is electrically connected to the purification device 110, the pressure detection component 120, the flow regulating device 130 and the water outlet device 140 respectively. The pressure detection component 120 is used to detect the water pressure of the water system and output the corresponding pressure parameter to the control module; the control module is used to obtain the pressure parameter of the water system during the water production process of the purification device 110; when it is determined according to the pressure parameter that the water pressure of the water system is greater than the preset pressure threshold, it is determined whether a water extraction stop instruction is received; if the water extraction stop instruction is not received, the purification device 110 is controlled to continue water production.

[0055] In an exemplary embodiment, as shown in FIG3 , a method for controlling a water system of a water purifier is provided, and the method is applied to a control module of a water system of a water purifier in FIG1 as an example for description, and includes the following steps 302 to 306 . Among them:

[0056] Step 302, during the water production process of the purification device, obtain the pressure parameters of the water system.

[0057] In actual implementation, the pressure detection component detects the water pressure between the purification device and the flow regulating device to obtain the pressure parameter of the water system. The control module obtains the pressure parameter through the pressure detection component.

[0058] The way in which the control module obtains the pressure parameter through the pressure detection component can be set according to actual conditions. In some embodiments, the pressure detection component includes a pressure switch connected to the control module, and the pressure switch is used to monitor the water pressure of the waterway in which it is located, and when it detects that the water pressure exceeds the preset pressure threshold, it sends a corresponding pressure parameter signal, and the pressure parameter signal indicates that the current water pressure of the waterway system is greater than the preset pressure threshold. The control module can determine that the water pressure of the waterway system is greater than the preset pressure threshold by obtaining the pressure parameter.

[0059] In other embodiments, the pressure detection component is used to detect the water pressure of the waterway in which it is located, and transmits the pressure parameter corresponding to the water pressure to the control module in real time, and the control module determines whether the pressure parameter representing the water pressure value is greater than the preset pressure threshold. When the pressure parameter is greater than the preset pressure threshold, it is determined that the water pressure of the waterway system is greater than the preset pressure threshold; when the pressure parameter is less than or equal to the preset pressure threshold, it is determined that the water pressure of the waterway system is less than or equal to the preset pressure threshold.

[0060] When the water pressure of the water system is greater than the preset pressure threshold, the control module executes step 204: determining whether a water-taking stop instruction is received.

[0061] The water extraction stop instruction is input by the user, and after receiving the water extraction stop instruction, the control module controls the water outlet component to stop discharging water. The method in which the user inputs the water extraction stop instruction does not need to be limited. For example, the water purifier includes a water extraction stop button or a control panel connected to the control module, and the user inputs the water extraction stop instruction through the water extraction stop button or the control panel of the water purifier.

[0062] If the water extraction stop instruction is not received, step 306 is executed: controlling the purification device to continue producing water.

[0063] The control module controls the purification device to continue to produce water in a manner that does not need to be limited. In some embodiments, the control module may again send a signal to control the purification device to start producing water, so that the purification device responds to the signal and continues to start running. In some embodiments, the control module may no longer send any signal, and the purification device will not stop unless it receives a signal to stop producing water, thereby continuing to be in a water producing state.

[0064] It should be noted that in the related art water purifier, the control module relies on the state of the pressure switch to control the start and stop of the water production of the purification device, that is, when the pressure switch detects that the pressure of the water system is too high, the purification device is controlled to stop producing pure water, and when the pressure of the water system returns to normal, the purification device is controlled to continue to produce water. However, in the process of using the water purifier to take water, the pressure switch sometimes mistakenly detects high pressure. For example, when the pure water outlet pipe is too long or the pressure switch fails, the pressure switch will cause misdetection. Moreover, since the power of the heating module in the hot water branch cannot exceed a certain value (the current cannot exceed the national standard, otherwise there will be safety hazards), the maximum water flow rate flowing into the hot water branch will also be less than the water flow rate of pure water produced by the purification device during the production of hot water in the hot water branch. In this case, the pressure switch will also misdetect.

[0065] If the pressure switch mistakenly detects high pressure, the control module will mistakenly control the purification device to stop making water, resulting in the problem of frequent start and stop of the purification device. Frequent start and stop will cause unstable water flow in the hot water branch or the normal temperature water branch, which will manifest as unstable water output of the water purifier, low reliability, and will also affect the service life of the water purifier.

[0066] The control method of the water system of the above-mentioned water purifier obtains the pressure parameters of the water system during the water production process of the purification device; when it is determined based on the pressure parameters that the water pressure of the water system is greater than the preset pressure threshold, it is determined whether a water extraction stop instruction is received; if the water extraction stop instruction is not received, the purification device is controlled to continue to produce water. Therefore, in the process of the user using the water purifier to continuously extract water, if the user does not stop extracting water, even if the pressure parameters of the water system are large, the purification device will be controlled to continue to produce pure water, so that the water outlet device has sufficient water supply, and the water outlet stability of the water outlet device is improved. Thereby, the situation in which the purification device is frequently started and stopped due to false detection of the pressure switch is improved, thereby improving the use stability of the water purifier and extending the service life of the water purifier.

[0067] In one embodiment, as shown in FIG. 4 , after step 304 , if a water extraction stop instruction is received, the control of the water system of the water purifier further includes: step 402 : controlling the purification device to stop water production.

[0068] It is understood that the control module will close the water outlet component to stop water outlet after receiving the water withdrawal stop instruction. At the same time, the control module also sends a water production stop signal to the purification device to control the purification device to stop producing pure water, thereby stopping the output of pure water to the hot water branch and the normal temperature water branch.

[0069] In this embodiment, the purification device is controlled to stop producing water upon receiving the water withdrawal stop instruction, which can reduce the energy consumption of the purification device. Since there is no need to continue to process and discharge unused purified water, the waste of water resources is also reduced.

[0070] In one embodiment, as shown in FIG. 5 , after step 304 , if a water extraction stop instruction is received, the control of the water system of the water purifier further includes steps 502 and 504 .

[0071] Step 502, obtaining the pressure parameters of the water system.

[0072] Step 504: When it is determined according to the pressure parameter that the water pressure of the water system is greater than a preset pressure threshold, the purification device is controlled to stop producing water.

[0073] In this embodiment, after the control module receives the instruction to stop taking water, it will immediately close the water outlet component to block the water flow output. However, the amount of water in the hot water branch may be small at this time. If the purification device is stopped at the same time, that is, pure water is no longer added to the hot water branch, then when the user tries to take water later, due to the limited amount of water in the hot water branch, if the power of the heating module is high, the water may be quickly heated to a high temperature, causing the water outlet component to spray water vapor or hot water, thus posing a safety hazard. In addition, insufficient water in the hot water branch may directly lead to water outflow interruption, affecting the normal use of the user. Moreover, insufficient water in the hot water branch will also cause the heating tube of the heating module to dry burn, posing a risk of damaging the heating tube.

[0074] In this embodiment, after receiving the instruction to stop taking water and closing the water outlet component, the pressure parameters of the water system will be obtained again to determine whether the water pressure of the water system is greater than the preset pressure threshold. If the water pressure of the water system is greater than the preset pressure threshold, it can be determined that the water system is full of water at this time, and the purification device is controlled to stop making water. If the water pressure of the water system is not greater than the preset pressure threshold, the purification device is controlled to continue making water until the water pressure of the water system is greater than the preset pressure threshold and the water system is full of water. Thereby, it can be ensured that when the user takes water again, there is enough water in the hot water branch, and there will be no dry burning of the heating tube, water vapor spraying from the water outlet component, or hot water interruption, which further improves the safety and reliability of the water purifier.

[0075] In one embodiment, before step 302, the control of the water system of the water purifier further includes:

[0076] Get water collection instructions;

[0077] The purification device is controlled to produce water according to the water intake instruction, and the opening of the flow regulating device of the water system is controlled according to the water intake instruction.

[0078] Specifically, the control module controls the water production of the purification device, controls the opening of the flow regulating device of the water system, and controls the water output of the water output device according to the water intake instruction.

[0079] The water extraction instruction is input by the user, and the water extraction instruction usually includes parameters such as water outlet mode, target water volume, and target water temperature. The target water volume is the desired water outlet volume set by the user. The water outlet mode may include a normal temperature water mode and a hot water mode. The target water temperature is the desired water outlet temperature set by the user in the hot water mode.

[0080] When the user selects the normal temperature water mode, the control module controls the second water outlet of the flow regulating device to be connected to the water inlet, so that the pure water produced by the purification device flows into the normal temperature water branch. The outlet water temperature of the normal temperature water cannot be adjusted. At this time, the control module controls the normal temperature water branch to open, and directly outputs the normal temperature pure water through the water outlet component. The control module adjusts the opening of the flow regulating device according to the target water volume, so that the outlet water volume of the normal temperature water is the target water volume.

[0081] When the user selects the hot water mode, the control module controls the first water outlet of the flow regulating device to be connected to the water inlet, so that the pure water produced by the purification device flows into the hot water branch. The control module adjusts the opening of the flow regulating device according to the target water volume, so that the hot water outlet water volume is the target water volume. At the same time, the control module will also control the heating module in the hot water branch to open, heat the inflowing pure water, and then output hot water corresponding to the target water temperature through the water outlet component (the actual temperature of the hot water may be equal to the target water temperature, or there may be an acceptable temperature deviation). When the control module controls the heating branch to produce hot water of the target water temperature, it can be achieved by precisely controlling the opening of the flow regulating device and the actual power of the heating module.

[0082] The method by which the user inputs the water extraction instruction does not need to be limited. For example, the water purifier includes a mode button, a water extraction button, a water volume selection button, a temperature selection button or a control panel electrically connected to the control module, and the user inputs the corresponding instruction through the mode button, the water extraction button, the water volume selection button, the temperature selection button or the control panel of the water purifier. In actual implementation, the water extraction button and the stop water extraction button can be one button. When the user triggers the button for the first time, the control module receives the water extraction instruction by default; when the user triggers the button again, the control module confirms that the stop water extraction instruction has been received; when the user triggers the button again, the control module receives the water extraction instruction by default, and repeats in this way.

[0083] In order to better understand the above embodiment, a detailed explanation is given below in conjunction with a specific embodiment. In one embodiment, the pressure detection component includes a pressure switch electrically connected to the control module.

[0084] When the user takes water at room temperature, after inputting the water taking instruction, the control module controls the purification device to start making water. At this time, the pure water flow produced by the purification module is consistent with the flow of normal temperature water, the water path maintains a low pressure state, and the pressure switch does not operate.

[0085] When the user takes hot water, after inputting the water taking instruction, the control module controls the purification device to start making water. At this time, the pure water flow produced by the purification module cannot be consistent with the hot water flow, and the pressure in the water circuit is high, which may trigger the pressure switch to cause it to operate and output the pressure parameter signal to the control module. After receiving the pressure parameter signal, the control module will also determine whether the user has input the stop water taking instruction. If the user has not input the stop water taking instruction, the water production will not be stopped even if the pressure switch detects high pressure. If the user inputs the stop water taking instruction, the control module will make a judgment again based on the detection result of the pressure switch. If high pressure is detected, a stop water production signal will be sent to the purification module; if high pressure is not detected, the purification module will continue to produce pure water to fill the water system with water.

[0086] The control method of the water system of the water purifier can ensure that the water outlet device has sufficient water supply and improve the water outlet stability of the water outlet device when the user uses the water purifier to continuously draw water. This improves the situation where the purification device is frequently started and stopped due to misdetection of the pressure switch, thereby improving the use stability of the water purifier and extending the service life of the water purifier.

[0087] After receiving the water withdrawal stop instruction and stopping water delivery, the water purification device will be controlled to stop water production when the water system is determined to be full of water. This ensures that when the user draws water again, there is enough water in the hot water branch, and there will be no dry burning of the heating tube, water vapor spraying from the water outlet component, or hot water interruption, further improving the safety and reliability of the water purifier.

[0088] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.

[0089] In one embodiment, a water system of a water purifier is provided. Referring to FIG. 1 , the water system of the water purifier may include a purification device 110 , a pressure detection assembly 120 , a flow regulating device 130 , a water outlet device 140 and a control module.

[0090] The water inlet end of the purification device 110 is used to receive raw water, and the purification device 110 is used to purify the received raw water to produce pure water.

[0091] The water outlet of the purification device 110 is connected to the water outlet device 140 through the flow regulating device 130, and the water outlet device 140 is used to provide the user with hot water or normal temperature water required by the user. Specifically, please refer to Figure 3, the water outlet device 140 includes a hot water branch 141, a normal temperature water branch 142 and a water outlet component 143. The water inlet end of the hot water branch 141 is connected to the first water outlet end A of the flow regulating device 130, and the water outlet end is connected to the water outlet component 143. The normal temperature water branch 142 is connected to the second water outlet end B of the flow regulating device 130, and the water outlet end is connected to the water outlet component 143.

[0092] The raw water first enters the purification device 110 for purification. The pure water obtained by the purification device 110 can be divided into two paths after passing through the flow regulating device 130. One path passes through the first water outlet A and enters the hot water branch 141 for heating. The heated water flows to the water outlet component 143 and is output as hot water. The other path passes through the second water outlet B, passes through the normal temperature water branch 142 and flows to the water outlet component 143 and is output as normal temperature water.

[0093] The flow regulating device 130 is used to regulate the flow of pure water flowing into the hot water branch 141 or the normal temperature water branch 142 to meet different needs of users.

[0095] The pressure detection component 120 is used to detect the water pressure of the water system and output the corresponding pressure parameters to the control module; the control module can control the purification device 110, flow regulating device 130 and water outlet device 140 of the water system of the water purifier according to the methods of the above embodiments.

[0096] The water system of the above-mentioned water purifier will control the purification device 110 to continuously produce pure water when the user uses the water purifier to continuously draw water, even if the pressure parameters of the water system are relatively large, so that the water outlet device 140 has sufficient water supply, thereby ensuring that the water outlet device 140 can output water stably, thereby improving the stability of use of the water purifier and extending the service life of the water purifier.

[0097] In actual implementation, the water system of the water purifier also includes a water inlet component, which is used to access the external waterway. In specific implementation, in a scenario where the raw water pressure provided by the external waterway is stable, the water inlet end of the purification device 110 can be directly connected to the water inlet component of the water system of the water purifier. In a scenario where the water source pressure is unstable, the water system of the water purifier may also include a pressure reducing valve, the water inlet end of the purification device 110 is connected to the water outlet end of the pressure reducing valve, and the water inlet end of the pressure reducing valve is connected to the water inlet component. The water inlet pressure is thereby adjusted by the pressure reducing valve to ensure that each device of the water purifier operates within an appropriate pressure range.

[0098] In one embodiment, as shown in FIG. 6 , the second water outlet B of the flow regulating device 130 is also connected to the purification device 110 .

[0099] During the use of the water purifier, the flow rate of pure water flowing out of the purification device 110 may be greater than the flow rate of the hot water branch 141 or the normal temperature water branch 142, resulting in a higher pressure inside the water system.

[0100] In this embodiment, the second water outlet B of the flow regulating device 130 is also connected to the purification device 110, and the pure water flowing out through the second water outlet B can also flow back to the purification device 110, thereby forming a pure water reflux loop. Therefore, when there is a high pressure inside the water channel, the pure water reflux loop can divert some water flow and return the excess pure water to the purification device 110, forming a cycle, so as to effectively prevent the water channel from being damaged by excessive pressure in the hot water flow channel.

[0101] In one embodiment, as shown in Figure 7, the purification device 110 includes a first purification component 111, a second purification component 112 and a third purification component 113, the water inlet end of the first purification component 111 is used to access the raw water to be purified, the water outlet end of the first purification component 111 is connected to the water inlet end of the second purification component 112, the water outlet end of the second purification component 112 is connected to the water inlet end of the third purification component 113, and the water outlet end of the third purification component 113 serves as the water outlet end of the purification device 110.

[0102] Specifically, the first purification component 111 may be a preliminary filtering component for preliminary purification of raw water. The second purification component 112 may be a deep purification component for deep purification of water preliminarily purified by the first purification component 111. The third purification component 113 may be a taste improvement component for filtering the deeply purified water again to improve the taste of the pure water finally obtained.

[0103] Exemplarily, the second purification component 112 can use one or more of an RO membrane filter element, an ultrafiltration membrane filter element, a ceramic membrane filter element, and a nanofiltration membrane filter element. In one embodiment, the second purification component 112 uses an RO membrane filter element. The first purification component 111 can use a pre-filter element, and the third purification component 113 can use a post-filter element. In actual implementation, the pre-filter element and the post-filter element can be integrated into a composite filter element. The pre-filter element can be a PAC filter element or PP+pre-activated carbon or other filter element forms, and the post-filter element can be an activated carbon filter element or ultrafiltration+post-activated carbon or other filter element forms.

[0104] The raw water to be purified first passes through the pre-filter element for pre-treatment to filter out impurities such as mud, rust, and solid pollutants in the water, and then flows into the RO membrane filter element for filtration treatment to filter out tiny pollutants such as bacteria and viruses in the water. The clean water after filtration treatment is further filtered through the post-filter element to absorb residual odors and colors in the water, improve the taste, and obtain pure water.

[0105] It can be understood that in actual implementation, the purification device 110 may also include a water inlet valve, a flow meter, a pressure-stabilizing pump, and a concentrated water regulating valve. In one embodiment, please refer to FIG. 7 , the water inlet valve 114, the first flow meter 115, and the pressure-stabilizing pump 116 are arranged between the first purification component 111 and the second purification component 112. The water preliminarily purified by the first purification component 111 is pressurized by the pressure-stabilizing pump 116 and flows to the second purification component 112 for filtering. The water inlet valve 114 is used to control the flow of water flowing into the second purification component 112. The first flow meter 115 can use a pulse counter to count the water flow. The concentrated water regulating valve 117 is arranged on the concentrated water pipeline connected to the second purification component 112 to control the on-off of the concentrated water pipeline.

[0106] The purification device 110 may also include a first TDS (Total Dissolved Solids) detection component 118 disposed at the water outlet of the first purification component 111, for detecting water quality. The water inlet valve 114, the first flow meter 115, the concentrated water regulating valve 117, the first TDS detection component 118, and the pressure-stabilizing pump 116 are all electrically connected to the control module, and the first TDS detection component 118, the first flow meter 115, and the pressure-stabilizing pump 116 can send their respective detection signals to the control module, which helps the control module to specifically control each component in the water production device 110, the flow regulating device 120, the normal temperature water branch 142, and the hot water branch 141.

[0107] When the control module controls the purification device 110 to start water production, the control module may specifically send a water production start signal to the water inlet valve 114, the pressure-stabilizing pump 116, and the concentrated water regulating valve 117 to control the water inlet valve 114, the pressure-stabilizing pump 116, and the concentrated water regulating valve 117 to open. When the control module controls the purification device 110 to stop water production, the control module may send a water production stop signal to the water inlet valve 114, the pressure-stabilizing pump 116, and the concentrated water regulating valve 117 to control the water inlet valve 114 to close, the pressure-stabilizing pump 116 to stop working, and the concentrated water regulating valve 117 to close.

[0108] In one embodiment, the water system of the water purifier further includes a pure water reflux valve 601 electrically connected to the control module, and the second water outlet B of the flow regulating device 130 is connected to the purification device 110 through the pure water reflux valve 601 .

[0109] Specifically, the water path where the pure water reflux valve 601 is located can be connected to the water path between the first purification component 111 and the second purification component 112, so that the refluxed pure water forms a cycle. The pure water reflux valve 601 can be a solenoid valve to adjust the on-off and precise water flow of the refluxed pure water.

[0110] In one embodiment, the water system of the water purifier further includes an anti-backflow component 602, which is disposed between the pure water reflux valve 601 and the purification device 110 to prevent the water flow of the purification device 110 from backflowing, thereby improving the stability of the water system. The anti-backflow component 602 may be a pure water reflux check valve, which is specifically disposed between the waterway connecting the first purification component 111 and the second purification component 112 and the pure water reflux valve 601.

[0111] It can be understood that in actual implementation, those skilled in the art can set more or fewer components in the water system according to actual needs. For example, in some embodiments, the water system can also include a second flow meter 603, a water inlet temperature sensing package 604, and a second TDS detection component 605 arranged between the pressure detection component 120 and the flow regulating device 130. The second flow meter 603 can use a pulse counter to detect the water flow of pure water. The water inlet temperature sensing package 604 is used to detect the water temperature of pure water. The second TDS detection component 605 is used to detect the water quality of pure water. The second flow meter 603, the water inlet temperature sensing package 604, and the second TDS detection component 605 are all electrically connected to the control module to send their respective detection signals to the control module, which helps the control module to specifically control each component in the water production device 110, the flow regulating device 120, the normal temperature water branch 142, and the hot water branch 141.

[0112] In some embodiments, the hot water branch 141 includes a heating module 1411 , a water inlet end of the heating module 1411 is connected to a first water outlet end A of the flow regulating device 130 , and a water outlet end of the heating module 130 is connected to a water outlet assembly 143 .

[0113] The normal temperature water branch 142 includes a normal temperature water control switch 1421, the water inlet end of the normal temperature water control switch 1421 is connected to the second water outlet end B of the flow regulating device 130, and the water outlet end of the normal temperature water control switch 1421 is connected to the water outlet assembly 143. The normal temperature water control switch 1421 can be set according to actual conditions. Exemplarily, the normal temperature water control switch 1421 can be a normal temperature water control solenoid valve.

[0114] In some embodiments, the hot water branch 141 may also include a hot water temperature sensing package 1412 and a water outlet temperature sensing package 1413, both of which are arranged in the water path between the heating module 1411 and the water outlet assembly 143. The hot water temperature sensing package 1412 is arranged near the water outlet end of the heating module 1411 to collect the temperature of the hot water heated by the heating module 1411. The water outlet temperature sensing package 1413 is arranged near the water outlet assembly 143 to collect the temperature of the water provided to the user. The hot water temperature sensing package 1412 and the water outlet temperature sensing package 1413 are both electrically connected to the control module to send their respective detection signals to the control module, so that the control module can perform more specific control on each component in the water making device 110, the flow regulating device 120 and the heating module 1411.

[0115] In one embodiment, the flow regulating device 130 includes a stepless regulating valve electrically connected to the control module, the water inlet end of the stepless regulating valve is connected to the water outlet end of the purification device 110, the first water outlet end of the stepless regulating valve is connected to the hot water branch 141 in the water outlet device 140, and the second water outlet end of the stepless regulating valve is connected to the normal temperature water branch 142 in the water outlet device 140 and the purification device 110.

[0116] The stepless regulating valve has a stepless regulating function. Its continuously adjustable valve opening can achieve fine adjustment of the water flow, making the adjustment of the water flow more accurate and efficient, thereby meeting the needs of hot water output at different gears. Moreover, its overall volume is small and occupies little space. This improves the space utilization rate in the water purifier, and is more conducive to the miniaturization design and portability of the water purifier equipment. In addition, the stepless regulating valve has higher working stability and can resist external interference. Therefore, the stable operation of the stepless regulating valve can improve the continuity and reliability of hot water output, reduce the failure rate of the water system of the water purifier, and improve the reliability of the water purifier.

[0120] The start-stop judgment module 804 is used to judge whether a water-taking stop instruction is received when it is determined according to the pressure parameter that the water pressure of the water system is greater than a preset pressure threshold.

[0121] The start-stop control module 806 is used to control the purification device to continue producing water if no water intake stop instruction is received.

[0122] In one embodiment, the start-stop control module 806 is further configured to control the purification device to stop producing water if a water extraction stop instruction is received.

[0123] In one embodiment, the start-stop control module 806 is also used to obtain the pressure parameters of the water system if a water intake stop instruction is received; when it is determined according to the pressure parameters that the water pressure of the water system is greater than a preset pressure threshold, the purification device is controlled to stop water production.
