[0002] As water purifiers are used for longer periods, excessive bacteria levels remain a persistent problem. Schools, hospitals, and government agencies now conduct regular bacterial tests on their water purification equipment, and health and safety have always been the core principles of the water purification industry.

[0003] Commercial water purifiers are used in public places, and the population using them for drinking water is much larger, making water safety an even greater concern. However, market sampling shows that commercial water purifiers frequently have excessive bacteria levels, seriously threatening people's drinking water health. Therefore, simpler and more effective sterilization technologies have become a demand in the commercial water purifier market. Summary of the Invention

[0005] The embodiments of the present invention achieve the above objectives through the following technical solutions.

[0006] In a first aspect, embodiments of the present invention provide a sterilization control method, which is applied to a flow-through sterilization device. The sterilization control method includes: acquiring a water flow signal, the water flow signal including an outlet water signal and a shut-off water signal; responding to the outlet water signal, controlling the flow-through sterilization device to start sterilization after a preset outlet water time according to the signal acquisition time of the outlet water signal; and responding to the shut-off water signal, controlling the flow-through sterilization device to shut off sterilization.

[0007] In some embodiments, after controlling the flow-through sterilization device to turn off sterilization, the sterilization control method further includes: obtaining the standby time; when the standby time is greater than the standby time threshold, controlling the flow-through sterilization device to perform sterilization in a preset sterilization mode.

[0008] In some embodiments, controlling the flow-through sterilization device to perform sterilization in a preset sterilization mode includes: controlling the flow-through sterilization device to turn on sterilization and continue for a first duration; controlling the flow-through sterilization device to turn off sterilization and continue for a second duration; wherein the turning on sterilization and turning off sterilization are performed alternately.

[0009] In some implementations, the second duration is greater than or equal to 100 times the first duration.

[0010] In some embodiments, controlling the flow-through sterilization device to shut down sterilization and continue for a second period of time includes: controlling the flow-through sterilization device to be in a standby state for a second period of time, wherein the sterilization function of the flow-through sterilization device in the standby state is turned off.

[0011] In some implementations, controlling the flow-through sterilization device to shut off sterilization includes: controlling the flow-through sterilization device to delay shutting off sterilization for a preset water shut-off time based on the signal acquisition time of the water shut-off signal.

[0012] In some implementations, the preset water shut-off time is greater than the preset water outlet time.

[0013] Secondly, embodiments of the present invention also provide a sterilization control device, which is applied to a flow-through sterilization device. The sterilization control device includes a signal acquisition module, a first control module, and a second control module. The signal acquisition module is used to acquire water flow signals, including water outlet signals and water shut-off signals. The first control module is used to respond to the water outlet signal and control the flow-through sterilization device to start sterilization for a preset time according to the signal acquisition time of the water outlet signal. The second control module is used to respond to the water shut-off signal and control the flow-through sterilization device to shut off sterilization.

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0031] Please see Figure 1 This invention provides a sterilization control method applied to a flow-through sterilization device 100, which can be used as the terminal water outlet of a water purification device 200. The water purification device 200 can be a water purifier or a combined water purifier and drinking water machine. The water purification device 200 can be a household device or a commercial device.

[0032] The inlet of the flow-through sterilizer 100 can be connected to the water tank 300 of the water purifier 200 via a pipeline. The water purifier 200 can be equipped with a switch valve 400 on this pipeline, which can selectively open or close the pipeline. For example, when a user needs to draw water, the switch valve 400 can open the pipeline, allowing water from the water tank 300 to flow into the flow-through sterilizer 100 and ultimately exit through its outlet. Conversely, when the user has finished drawing water, the switch valve 400 can close the pipeline, preventing water from flowing into the flow-through sterilizer 100 and thus stopping the flow-through sterilizer 100 from discharging water.

[0033] The flow-through sterilization device 100 may be equipped with a sterilization module 110 to sterilize the water entering the device. The sterilization module 110 can sterilize the water using ultraviolet light. For example, the sterilization module 110 may include a deep ultraviolet light-emitting diode (LED) lamp. The deep ultraviolet LED lamp can emit ultraviolet light with a wavelength of approximately 253.7nm, which has a high irradiation intensity and can kill bacteria and viruses in a short time, resulting in a strong sterilization effect. This helps the flow-through sterilization device 100 to sterilize the water flowing through it more comprehensively and evenly.

[0034] Figure 1The schematic diagram of the water purification device 200 shown is merely an example. The structure and application scenarios of the water purification device 200 described in the embodiments of the present invention are for the purpose of more clearly illustrating the technical solutions of the embodiments of the present invention, and do not constitute a limitation on the technical solutions provided by the embodiments of the present invention. As those skilled in the art will know, with the evolution of the hardware structure of water purification devices and the emergence of new application scenarios, the technical solutions provided by the embodiments of the present invention are also applicable to similar technical problems.

[0035] Please see Figure 1 and Figure 2 The sterilization and control method includes steps 010, 020 and 030.

[0036] Step 010: Acquire water flow signal.

[0037] The water flow signal includes both a water outlet signal and a water shut-off signal. The water flow signal can be generated based on user input.

[0038] For example, the water purifier 200 can be equipped with a touch screen displaying functions such as water dispensing and water shut-off options. When a user needs to dispense water from the water purifier 200, the user can trigger and generate a water dispensing signal by touching the water dispensing option; when the user has finished dispensing water, the user can trigger and generate a water shut-off signal by touching the water shut-off option.

[0039] In addition to receiving user input via a touchscreen display, the water purifier 200 can also receive user input via buttons. For example, the water purifier 200 can be equipped with a water dispensing button and a water shut-off button. When a user needs to dispense water from the water purifier 200, the user can press the water dispensing button to trigger and generate a water dispensing signal; when the user has finished dispensing water, the user can press the water shut-off button to trigger and generate a water shut-off signal.

[0040] The water purification device 200 may also be equipped with a communication module, which can communicate with the user's terminal so that the user can trigger and generate water output signals and water shut-off signals through the application software associated with the water purification device 200.

[0041] The water shut-off signal can be set to automatically trigger the water shut-off signal after a preset delay when a water outlet signal is received, thus eliminating the need for the user to manually trigger the water shut-off signal and simplifying the user's operation.

[0042] The preset interval duration can be set according to actual conditions. For example, the preset interval duration can be set according to the water output of the flow-through sterilization device 100 per unit time, or the preset interval duration can be adjusted to the user's personalized settings.

[0043] In some implementations, the preset interval duration can be from five to fifteen seconds, for example, the preset interval duration can be five seconds, six seconds, seven seconds, eight seconds, nine seconds, ten seconds, twelve seconds, fourteen seconds, fifteen seconds, etc.

[0044] Step 020: In response to the water outlet signal, based on the signal acquisition time of the water outlet signal, control the flow-through sterilization device to start sterilization after a preset water outlet time.

[0045] In this way, the water flow can be sterilized during dispensing, which helps ensure the safety of users' drinking water and other water use. In addition, since it takes a certain amount of time for the water to flow from the water tank 300 into the flow-through sterilization device 100, by controlling the flow-through sterilization device 100 to start sterilization after a certain period of time following the water dispensing signal, the flow-through sterilization device 100 will not start sterilization synchronously with the water dispensing signal, thus avoiding the sterilization operation being ineffective. This effectively avoids the situation where sterilization starts prematurely before the water has flowed into the flow-through sterilization device 100, which helps save electricity and reduce energy waste.

[0046] The preset water output time can be set according to actual conditions. For example, the preset water output time can be determined based on the time taken from when the switch valve 400 receives the instruction to when it completes the action of connecting the pipeline, the length of the pipeline between the water tank 300 and the flow-through sterilization device 100, the diameter of the pipeline, the water pressure and water temperature of the water tank 300, etc.

[0047] The preset water output time can be equal to the time it takes for water to flow from the water tank 300 into the flow-through sterilization device 100. The preset water output time can also be slightly shorter than the time taken, which helps to ensure that sterilization can be started when water flows into the flow-through sterilization device 100.

[0048] When the flow-through sterilization device 100 is turned on for sterilization, the sterilization module 110 can be in an illuminated state.

[0049] Step 030: In response to the water shut-off signal, control the flow-through sterilization device to shut off sterilization.

[0050] The water shut-off signal indicates that the user has finished drawing water, and the flow-through sterilization device 100 will not have a continuous flow of water entering. After the water is shut off, the sterilization will be turned off, which helps to save electricity and reduce energy waste.

[0051] The flow-through sterilization device 100 can be shut down for sterilization purposes, but it can also remain operational, for example, the sterilization module 110 of the flow-through sterilization device 100 can be turned off. Alternatively, the flow-through sterilization device 100 can be stopped altogether.

[0052] Please see Figure 1 and Figure 3In some embodiments, the present invention also provides a sterilization control method, which includes steps 010, 020 and 030.

[0053] Step 010: Acquire water flow signal.

[0054] Step 020: In response to the water outlet signal, based on the signal acquisition time of the water outlet signal, control the flow-through sterilization device to start sterilization after a preset water outlet time.

[0055] Step 030: In response to the water shut-off signal, control the flow-through sterilization device to shut off sterilization.

[0056] Steps 010 to 030 can refer to the corresponding processes in the aforementioned method implementation, and will not be repeated here.

[0057] Controlling the flow-through sterilization device to shut off sterilization includes: based on the signal acquisition time of the water shut-off signal, controlling the flow-through sterilization device to shut off sterilization after a preset water shut-off time. That is, step 030 includes step 031, step 031: in response to the water shut-off signal, based on the signal acquisition time of the water shut-off signal, controlling the flow-through sterilization device to shut off sterilization after a preset water shut-off time.

[0058] Since some water still flows from the water tank 300 to the flow-through sterilization device 100 after the water is turned off, by controlling the flow-through sterilization device 100 to shut off sterilization a certain period of time after responding to the water-off signal, the flow-through sterilization device 100 will not shut off sterilization synchronously with the water-off signal, resulting in some water flowing out without sterilization. This effectively avoids the situation where sterilization is shut off prematurely before the water flow has completely flowed into the flow-through sterilization device 100, which helps to ensure the safety of users' drinking water and water use.

[0059] The preset water shut-off time can be set according to actual conditions. For example, the preset water shut-off time can be determined based on the time taken from when the switch valve 400 receives the instruction to when it completes the action of shutting off the pipeline, the length of the pipeline between the water tank 300 and the flow-through sterilization device 100, the diameter of the pipeline, the outlet water pressure of the water tank 300, the time taken for the water to flow from the inlet end to the outlet end of the flow-through sterilization device 100, the water temperature, etc.

[0060] The preset water shut-off time can be equal to the time it takes for water to flow from the water tank 300 into the flow-through sterilization device 100. The preset water shut-off time can also be slightly longer than the time taken, which helps to ensure that the flow-through sterilization device 100 can shut off sterilization after the remaining water has completely flowed out of its outlet.

[0061] In some implementations, the preset water shut-off time can be longer than the preset water outlet time. Since the water flow velocity during outlet operation is typically greater than after water shut-off, water can flow from the water tank 300 into the flow-through sterilizer 100 at a faster speed during outlet operation, resulting in a shorter time. After water shut-off, the water flow velocity typically decreases, and water flows from the pipe into the flow-through sterilizer 100 at a slower speed, resulting in a longer time. By setting the preset water shut-off time to be longer than the preset water outlet time, it is helpful to reasonably differentiate the water flow patterns according to actual conditions, thus helping to ensure the safety of users' drinking and general water use.

[0062] Please see Figure 1 and Figure 4 In some embodiments, after the flow-through sterilization device is shut down for sterilization, the sterilization control method may further include steps 040 and 050.

[0063] Step 040: Obtain standby time.

[0064] Standby time indicates the time elapsed since the last water discharge signal was received. Standby time indicates that the user has not triggered a water discharge signal during this period.

[0065] Step 050: When the standby time exceeds the standby time threshold, control the flow-through sterilization device to perform sterilization in the preset sterilization mode.

[0066] Thus, by controlling the flow-through sterilization device 100 to perform sterilization in a preset sterilization mode, it helps to avoid the growth of a large number of bacteria inside the flow-through sterilization device 100 due to prolonged periods without sterilization.

[0067] The standby time threshold can be set according to actual conditions. For example, the number of bacteria that grows varies depending on the structure of the water passage inside the flow-through sterilization device 100, and the standby time threshold can be set according to parameters such as the length and width of the water passage inside the flow-through sterilization device 100. For example, the standby time threshold can be three hours, two hours, etc.

[0068] Please see Figure 1 and Figure 5 In some embodiments, controlling the flow-through sterilization device to perform sterilization in a preset sterilization mode includes: controlling the flow-through sterilization device to turn on sterilization and continue sterilization for a first duration; controlling the flow-through sterilization device to turn off sterilization and continue sterilization for a second duration; wherein, turning on sterilization and turning off sterilization alternate. That is, step 050 includes step 051, step 051: when the standby time is greater than the standby time threshold, controlling the flow-through sterilization device to turn on sterilization and continue sterilization for a first duration; controlling the flow-through sterilization device to turn off sterilization and continue sterilization for a second duration; wherein, turning on sterilization and turning off sterilization alternate.

[0069] Alternating between turning on sterilization and turning off sterilization means alternating between a state where the flow-through sterilization device 100 is turned on for a first duration and a state where the flow-through sterilization device 100 is turned off for a second duration.

[0070] In this way, by reasonably controlling the duration of the flow-through sterilization device 100 on and off, it helps to ensure that a large number of bacteria do not grow inside the flow-through sterilization device 100, thus ensuring the safety of users' drinking water and other water use. At the same time, it also helps to avoid wasting electricity by continuously turning on the flow-through sterilization device 100 for sterilization, thus reducing energy waste.

[0071] The first and second durations can be set according to the actual situation. The first duration can be three to seven seconds, for example, three, four, five, six, seven seconds, etc. The second duration can be thirty to seventy minutes, for example, thirty, forty, fifty, sixty, seventy minutes, etc.

[0072] In some implementations, the second duration can be greater than or equal to 100 times the first duration, thereby helping to ensure that the duration of sterilization when the flow-through sterilizer 100 is off is much longer than the duration of sterilization when it is on. This helps to avoid the flow-through sterilizer 100 frequently turning on and off, which would affect its service life. At the same time, it also helps to avoid the flow-through sterilizer 100 being on for too long, which would waste electricity and help to reduce energy waste.

[0073] The second duration can be 100 to 800 times greater than or equal to the first duration. For example, the second duration can be 100, 110, 120, 150, 200, 250, 300, 500, 700, or 800 times greater than the first duration. This helps to balance ensuring users' drinking water and water safety with reducing energy waste.

[0074] Please see Figure 1 and Figure 6 In some embodiments, controlling the flow-through sterilization device to shut down sterilization and continue for a second duration includes: controlling the flow-through sterilization device to be in standby mode and continue for a second duration. That is, step 051 includes step 052, where step 052: when the standby duration is greater than a standby duration threshold, controlling the flow-through sterilization device to turn on sterilization and continue for a first duration; controlling the flow-through sterilization device to be in standby mode and continue for a second duration; wherein, turning on sterilization and turning off sterilization alternate.

[0075] In this context, the sterilization function of the flow-through sterilization device 100 is turned off when it is in standby mode. The standby mode of the flow-through sterilization device 100 can mean that the flow-through sterilization device 100 operates at a lower power, or it can mean that the flow-through sterilization device 100 is always powered on, and the flow-through sterilization device 100 is neither de-energized nor completely stopped.

[0076] This allows the flow-through sterilizer 100 to quickly activate from standby mode to sterilization mode when switching from sterilization off to sterilization on, facilitating rapid attainment of maximum power for sterilization and improving its sterilization capability and response speed during the first time period. Furthermore, since the flow-through sterilizer 100 operates continuously throughout both the first and second time periods, it helps avoid repeated stopping and starting, which could negatively impact its lifespan.

[0077] Please see Figure 1 and Figure 7 In some implementations, the sterilization control method may include the following steps:

[0078] Step 010: Acquire water flow signal.

[0079] Step 020: In response to the water outlet signal, based on the signal acquisition time of the water outlet signal, control the flow-through sterilization device to start sterilization after a preset water outlet time.

[0080] Step 031: In response to the water shut-off signal, based on the signal acquisition time of the water shut-off signal, control the flow-through sterilization device to delay the preset water shut-off time to shut off sterilization.

[0081] Step 040: Obtain standby time.

[0082] Step 052: When the standby time exceeds the standby time threshold, control the flow-through sterilization device to turn on sterilization and continue for a first time; control the flow-through sterilization device to be in standby mode and continue for a second time; wherein, turning on sterilization and turning off sterilization alternate.

[0083] Please see Figure 1 and Figure 8 This invention also provides a sterilization control device 500, which is applied to a flow-through sterilization device 100. The sterilization control device 500 is capable of executing the sterilization control method of any of the above embodiments.

[0084] The sterilization control device 500 includes a signal acquisition module 510, a first control module 520, and a second control module 530.

[0085] The signal acquisition module 510 is used to acquire water flow signals, which include water outflow signals and water shut-off signals.

[0086] The first control module 520 is used to respond to the water outlet signal and, based on the signal acquisition time of the water outlet signal, control the flow-through sterilization device 100 to start sterilization after a preset time delay.

[0087] The second control module 530 is used to control the flow-through sterilization device 100 to shut off sterilization in response to the water shut-off signal.

[0088] The sterilization control device 500 of this invention controls the flow-through sterilization device 100 to sterilize the water flow when it is discharged, which helps to ensure the safety of users' drinking water and other water use. At the same time, it effectively avoids the situation where sterilization is turned on too early before the water flow enters the flow-through sterilization device 100. After the water is turned off, there will be no continuous water flow into the flow-through sterilization device 100, and sterilization will be turned off after the water is turned off. This helps to save electricity and reduce energy waste.

[0089] In some implementations, the second control module 530 can also be used to control the flow-through sterilization device 100 to delay the sterilization process for a preset water shut-off time in response to the water outlet signal, based on the signal acquisition time of the water shut-off signal.

[0090] Please see Figure 1 and Figure 9 In some embodiments, the sterilization control device 500 may further include a duration acquisition module 540 and a mode control module 550.

[0091] The duration acquisition module 540 can be used to obtain the standby duration.

[0092] The mode control module 550 can be used to control the flow sterilization device 100 to perform sterilization in a preset sterilization mode when the standby time exceeds the standby time threshold.

[0093] In some implementations, the mode control module 550 can also be used to control the flow-through sterilization device 100 to turn on sterilization and continue for a first duration when the standby duration is greater than the standby duration threshold; and to control the flow-through sterilization device 100 to turn off sterilization and continue for a second duration; wherein, turning on sterilization and turning off sterilization are performed alternately.

[0094] In some implementations, the mode control module 550 can also be used to control the flow-through sterilization device 100 to start sterilization and continue for a first duration when the standby duration is greater than the standby duration threshold; control the flow-through sterilization device 100 to be in standby mode and continue for a second duration, and turn off the sterilization function of the flow-through sterilization device 100 in standby mode; wherein, the start and stop of sterilization are performed alternately.

[0095] Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific working process of the above-described device and module can be referred to the corresponding process in the foregoing method implementation, and will not be repeated here.

[0096] In the above embodiments, the coupling between modules can be electrical, mechanical, or other forms of coupling. Each functional module can be integrated into a single processing module, or each module can exist physically separately, or two or more modules can be integrated into a single module. The integrated module can be implemented in hardware or as a software functional module.

[0097] The sterilization control device 500 can be installed in the water purification equipment 200, and all functions of the sterilization control device 500 can be implemented by the controller, electronic control board, or control board of the water purification equipment 200 itself. Alternatively, the sterilization control device 500 can be installed in the flow-through sterilization device 100, and all functions of the sterilization control device 500 can be implemented by the controller, electronic control board, or control board of the flow-through sterilization device 100 itself. Alternatively, some functions of the sterilization control device 500 can be implemented by one of the controllers, electronic control boards, or control boards of the water purification equipment 200 itself, and other functions can be implemented by the controller, electronic control board, or control board of the flow-through sterilization device 100. Alternatively, the sterilization control device 500 can be made into an independent device or equipment, installed outside or inside the water purification equipment 200, and the sterilization control device 500 and the water purification equipment 200 can communicate via wired and / or wireless means.

[0098] Please see Figure 10 This invention also provides a water purification device 200, which includes a flow-through sterilization device 100, a processor 210, a memory 220, and an application program. The application program is stored in the memory 220 and configured to be executed by the processor 210. The application program is configured to execute the sterilization control method of any of the above embodiments, for example, executing step 010: acquiring a water flow signal; executing step 020: in response to a water outlet signal, controlling the flow-through sterilization device to start sterilization after a preset water outlet time according to the signal acquisition time of the water outlet signal; executing step 030: in response to a water shut-off signal, controlling the flow-through sterilization device to shut off sterilization.

[0099] Processor 210 may include one or more cores for data processing and message matrix units. Processor 210 connects to various parts of the electronic device using various interfaces and lines, and performs various functions of the cooking device and processes data by running or executing instructions, programs, code sets, or instruction sets stored in memory 220, and by calling data stored in memory 220. Processor 210 may be implemented using at least one hardware form of Digital Signal Processing (DSP), Field-Programmable Gate Array (FPGA), or Programmable Logic Array (PLA). Processor 210 may integrate one or more of a Central Processing Unit (CPU), Graphics Processing Unit (GPU), and modem. The CPU primarily handles the operating system, user interface, and applications; the GPU is responsible for rendering and drawing the displayed content; and the modem handles wireless communication. It is understood that the modem may also not be integrated into processor 210 and may be implemented separately using a communication chip.

[0100] The memory 220 may include random access memory (RAM) or read-only memory (ROM). The memory 220 can be used to store instructions, programs, code, code sets, or instruction sets. The memory 220 may include a program storage area and a data storage area. The program storage area may store instructions for implementing an operating system, instructions for implementing at least one function, instructions for implementing the various method implementations described above, etc. The data storage area may also store data created by the terminal during use.

[0101] The water purification device 200 of this invention can sterilize the water flow when it is discharged, which helps to ensure the safety of users' drinking water and water use. At the same time, it effectively avoids the situation where sterilization is turned on too early before the water flow enters the flow sterilization device 100. After the water is turned off, the flow sterilization device 100 will not have a continuous flow of water entering it, and sterilization will be turned off after the water is turned off. This helps to save electricity and reduce energy waste.

[0102] Please see Figure 11This application also provides a computer-readable storage medium 600, which stores computer-executable instructions 610.
