Description

Technical Field

[0001] This application relates to the field of water treatment technology, and in particular to a method for sterilizing a faucet, a control device, an electronic control device, and a computer-readable storage medium. Background Technology

[0002] In modern life, water quality safety is receiving increasing attention, especially in household and public water use. To ensure the safety of drinking water, many faucets and water treatment devices are designed with sterilization functions. Among them, UV (ultraviolet) sterilization technology has become a widely used water disinfection method due to its high efficiency, environmental friendliness, and lack of chemical byproducts.

[0003] Traditional UV sterilization devices used in faucets primarily rely on fixed sterilization power settings. The main drawback of this method is its inability to dynamically adjust to changes in actual water flow. Fluctuations in water flow directly affect the sterilization effect of the UV module. If the water flow increases but the UV module's sterilization power doesn't increase accordingly, it may result in insufficient sterilization, failing to effectively remove bacteria and pathogens from the water. Conversely, setting the sterilization power too high when the water flow is low leads to energy waste and unnecessary power consumption.

[0004] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is prior art. Summary of the Invention

[0005] The main objective of this application is to provide a sterilization method, control device, electronic control device, and computer-readable storage medium for a faucet, ensuring that the faucet maintains an effective sterilization effect under different usage conditions while avoiding unnecessary energy waste, thereby improving the sterilization efficiency of the faucet.

[0006] To achieve the above objectives, this application provides a method for sterilizing a faucet, comprising the following steps:

[0007] When the tap is turned on, the water flow is detected by a flow sensor inside the water inlet pipe;

[0008] The sterilization power of the UV module is adjusted according to the water flow rate; the higher the water flow rate, the higher the sterilization power is adjusted; the UV module is located in the cavity before the water outlet of the faucet.

[0009] Calculate the expected irradiation dose under the current water flow rate and the sterilization power, and detect the irradiation intensity inside the cavity;

[0010] Calculate the actual radiation dose under the current irradiation intensity and check whether the actual radiation dose meets the expected radiation dose;

[0011] If not, increase the sterilization power;

[0012] If so, then maintain the sterilization power to sterilize and produce water.

[0013] Optionally, before the step of calculating the actual radiation dose at the current irradiation intensity and detecting whether the actual radiation dose meets the expected radiation dose, the method further includes:

[0014] When it is detected that the expected irradiation dose does not meet the target sterilization rate requirement, the sterilization power is adjusted so that the expected irradiation dose meets the target sterilization rate requirement.

[0015] Optionally, the sterilization method for the faucet further includes:

[0016] When the tap is turned on, if it is not the first water production of the day, the system will check whether the water production interval exceeds the preset time.

[0017] If the flow rate is exceeded, then the step of adjusting the sterilization power of the UV module according to the water flow rate is executed.

[0018] If the threshold is not exceeded, the UV module is controlled to operate at the sterilization power of the previous water production, and the steps of calculating the expected irradiation dose under the current water flow rate and the sterilization power, and detecting the irradiation intensity in the cavity are performed.

[0019] Optionally, the sterilization method for the faucet further includes:

[0020] The usage status of the UV module is determined based on the degree of difference between the actual irradiation dose and the expected irradiation dose;

[0021] If the UV module is determined to be in abnormal condition, an alarm will be issued.

[0022] Optionally, the usage status includes the remaining lifespan of the UV module; the abnormal usage status includes the remaining lifespan being below a critical value.

[0023] Optionally, the cavity is a frustum, and the water outlet direction is from the bottom to the top of the frustum.

[0024] Optionally, the formula for calculating the expected irradiation dose is as follows:

[0025] G1 = P / V × h / v;

[0026] Wherein, P is the sterilization power, V is the volume of the frustum, h is the height of the frustum, and v is the water flow rate.

[0027] To achieve the above objectives, this application also provides an electronic control device, which includes: a memory, a processor, and a computer program stored in the memory and executable on the processor. When the computer program is executed by the processor, it implements the steps of the above-described faucet sterilization method.

[0028] To achieve the above objectives, this application also provides a sterilizing faucet, characterized in that it includes: a UV module, an irradiation intensity sensor, a flow sensor, and an electronic control device; the UV module and the irradiation intensity sensor are disposed in a cavity before the faucet outlet, the flow sensor is disposed in the faucet inlet pipe, and the electronic control device is disposed in a structural part outside the faucet water flow channel; the UV module, the irradiation intensity sensor, and the flow sensor are all electrically connected to the electronic control device; the electronic control device is the electronic control device described above.

[0029] To achieve the above objectives, this application also provides a computer-readable storage medium storing a computer program, which, when executed by a processor, implements the steps of the above-described faucet sterilization method.

[0030] The sterilization method, control device, electronic control device, and computer-readable storage medium for faucets provided in this application automatically adjust the sterilization power of the UV module based on the actual detected water flow and irradiation intensity. This ensures that the sterilization effect is maintained under different usage conditions while avoiding unnecessary energy waste, thus improving the sterilization efficiency of the faucet and making the use of the sterilizing faucet more environmentally friendly. Furthermore, it monitors and adjusts the irradiation dose in real time to achieve precise control of irradiation intensity and dose, ensuring that bacteria and pathogens in the water are fully eliminated, thereby enhancing the safety of drinking water.

[0038] Reference Figure 1 In one embodiment, the method for sterilizing a faucet includes:

[0039] Step S10: When the faucet is turned on, the water flow rate is detected based on the flow sensor in the water inlet pipe;

[0040] Step S20: Adjust the sterilization power of the UV module according to the water flow rate; wherein, the greater the water flow rate, the greater the sterilization power is adjusted; the UV module is installed in the cavity before the water outlet of the faucet;

[0041] Step S30: Calculate the expected irradiation dose under the current water flow rate and the sterilization power, and detect the irradiation intensity inside the cavity;

[0042] Step S40: Calculate the actual irradiation dose under the current irradiation intensity and check whether the actual irradiation dose meets the expected irradiation dose;

[0043] Step S50: If not, increase the sterilization power;

[0044] Step S60: If yes, continue sterilization and water production.

[0045] In this embodiment, the execution terminal can be an electronic control device, or other equipment or devices that control the electronic control device.

[0046] As described in step S10, the faucet includes a faucet body and a water inlet pipe connected to the faucet body; wherein, the inlet of the water inlet pipe can be a water supply device or pipe connected to a water inlet device; the water inlet pipe has a built-in flow sensor for detecting water flow.

[0047] When the faucet is detected to be open, the flow sensor is activated simultaneously to detect the water flow from the inlet pipe toward the faucet.

[0048] As described in step S20, a UV module is installed in the cavity before the water outlet of the faucet (i.e., the water outlet of the faucet body). This ensures that the water flow is fully exposed to UV radiation before passing through the water outlet. When the faucet is turned on, the UV module can also be activated simultaneously to generate ultraviolet light for sterilization and water purification.

[0049] When the UV module is running, its sterilization power can be adjusted based on the water flow rate detected by the flow sensor. The higher the detected water flow rate, the greater the sterilization power will be.

[0050] Optionally, the water flow rate can be defined into three levels: high, medium, and low flow rates. Among them, the sterilization power associated with high flow rate is greater than that associated with medium flow rate, and the sterilization power associated with medium flow rate is greater than that associated with low flow rate.

[0051] Optionally, the water flow rate can be measured by the water velocity; for example, if the water velocity is greater than 8 L / ml, it is a large flow rate; if the water velocity is between 3 L / ml and 8 L / ml, it is a medium flow rate; and if the water velocity is less than 3 L / ml, it is a small flow rate.

[0052] For example, the sterilization power associated with a high flow rate can be greater than 442mW; the sterilization power associated with a medium flow rate can be between (204mW, 442mW), preferably (251mW, 442mW); and the sterilization power associated with a low flow rate can be less than or equal to 204mW.

[0053] It should be understood that by adjusting the corresponding resistor, the operating current of the UV module can be adjusted, thereby adjusting the sterilization power of the UV module.

[0054] As described in step S30, the formula for calculating the expected irradiation dose G1 under the current water flow rate and the sterilization power is as follows:

[0055] G1 = P / V × h / v;

[0056] Wherein, P is the sterilization power, V is the volume of the cavity where the UV module is located, h is the height of the cavity where the UV module is located, and v is the water flow rate.

[0057] Optionally, an irradiation intensity sensor is also provided in the cavity where the UV module is located in the faucet to detect the irradiation intensity in the cavity where the UV module is located.

[0058] As described in step S40, after detecting the actual irradiation intensity, the actual irradiation dose G2 can be calculated based on the actual irradiation intensity:

[0059] G2 = F × t;

[0060] Where F is the actual irradiation intensity, and t is the time when water is irradiated by the UV module (which is negatively correlated with the water flow rate and affected by the specific design dimensions of the cavity in which the UV module is located, so its specific value needs to be determined according to the actual situation).

[0061] After calculating the actual irradiation dose, the actual irradiation dose is compared with the expected irradiation dose to check whether the actual irradiation dose meets the expected irradiation dose.

[0062] As described in step S50, if the actual irradiation dose is less than the expected irradiation dose, it indicates that the actual irradiation dose does not meet the expected irradiation dose. Therefore, the sterilization power of the UV module is increased so that the actual irradiation dose reaches the previously calculated expected irradiation dose.

[0063] As described in step S60, if the actual irradiation dose is detected to be greater than or equal to the expected irradiation dose, it indicates that the actual irradiation dose meets the expected irradiation dose. In this case, the UV module maintains its current sterilization power to sterilize and produce water.

[0064] In one embodiment, the sterilization power of the UV module is automatically adjusted based on the actual detected water flow and irradiation intensity. This ensures that the sterilization effect remains effective under different usage conditions while avoiding unnecessary energy waste (i.e., avoiding both energy waste caused by excessive UV module power and insufficient sterilization effect caused by excessive UV module power). This improves the sterilization efficiency of the faucet and makes the use of the sterilizing faucet more environmentally friendly. Furthermore, real-time monitoring and adjustment of the irradiation dose enables precise control of irradiation intensity and dose, ensuring that bacteria and pathogens in the water are fully eliminated and enhancing the safety of drinking water.

[0065] In one embodiment, based on the above embodiment, before the steps of calculating the actual radiation dose at the current irradiation intensity and detecting whether the actual radiation dose meets the expected radiation dose, the method further includes:

[0066] When it is detected that the expected irradiation dose does not meet the target sterilization rate requirement, the sterilization power is adjusted so that the expected irradiation dose meets the target sterilization rate requirement.

[0067] In this embodiment, after calculating the expected irradiation dose, the expected sterilization rate can be calculated based on the expected irradiation dose G1.

[0068]

[0069] Here, k is a constant proportional to the irradiation dose and the sterilization rate. The type, power, wavelength, and output light intensity of the UV lamp all affect the value of k; therefore, the value of k needs to be set according to actual conditions. However, in general, it can be seen that there is a direct proportional relationship between the irradiation dose and the sterilization rate.

[0070] After calculating the expected sterilization rate, it is compared with the target sterilization rate to check whether the expected irradiation dose meets the target sterilization rate requirement. The target sterilization rate can be set according to the specific drinking water quality standards of the region or user needs, such as 99%.

[0071] Optionally, if the expected sterilization rate is less than the target sterilization rate, it means that the expected irradiation dose does not meet the target sterilization rate requirement. In this case, the sterilization power of the UV module is increased to increase the expected irradiation dose, thereby enabling the expected sterilization rate to reach the target sterilization rate. If the expected sterilization rate is greater than or equal to the target sterilization rate, it means that the expected irradiation dose meets the target sterilization rate requirement. In this case, the calculated expected irradiation dose is retained and used for subsequent determination of whether the sterilization effect meets the standard.

[0072] This ensures that the faucet's sterilization effect meets the target sterilization rate requirements, enhancing the reliability of water disinfection.

[0073] In one embodiment, based on the above embodiments, the faucet sterilization method further includes:

[0074] When the tap is turned on, if it is not the first water production of the day, the system will check whether the water production interval exceeds the preset time.

[0075] If the flow rate is exceeded, then the step of adjusting the sterilization power of the UV module according to the water flow rate is executed.

[0076] If the threshold is not exceeded, the UV module is controlled to operate at the sterilization power of the previous water production, and the steps of calculating the expected irradiation dose under the current water flow rate and the sterilization power, and detecting the irradiation intensity in the cavity are performed.

[0077] In this embodiment, when the faucet is turned on, while detecting the water flow based on the flow sensor in the water inlet pipe, it also checks whether this is the first water production of the day. If it is the first water production of the day, then step S20 is executed; if it is not the first water production of the day, then it is necessary to first check whether the water production interval exceeds a preset time.

[0078] When the tap is turned on, the system calculates the interval between the current time and the last water production time. The preset duration is used to measure the length of the water production interval and can be set according to actual needs, such as 2 hours.

[0079] Optionally, if the water production interval exceeds the preset time, then the step of adjusting the sterilization power of the UV module according to the water flow rate (i.e., step S20) is then executed.

[0080] Optionally, if the water production interval does not exceed the preset time, the UV module is controlled to operate at the sterilization power of the previous water production, and the steps of calculating the expected irradiation dose under the current water flow and sterilization power and detecting the irradiation intensity in the cavity are directly executed (i.e., step S30).

[0081] When the water production interval is too long, it indicates that microorganisms or contaminants may have accumulated in the faucet. Adjusting the UV module's sterilization power according to the current water flow ensures that the required sterilization effect is achieved at the current water flow rate, avoiding insufficient sterilization. If the water production interval is short, the UV module is directly controlled to operate at the sterilization power of the previous water production. This avoids unnecessary power adjustments and ensures a stable sterilization effect even under frequent use.

[0082] In one embodiment, based on the above embodiments, the faucet sterilization method further includes:

[0083] The usage status of the UV module is determined based on the degree of difference between the actual irradiation dose and the expected irradiation dose;

[0084] If the UV module is determined to be in abnormal condition, an alarm will be issued.

[0085] In this embodiment, after calculating the actual irradiation dose and the expected irradiation dose, the degree of difference between the actual irradiation dose and the expected irradiation dose can be further determined, and the usage status of the UV module can be judged based on the degree of difference.

[0086] For example, a difference threshold can be set to determine whether the degree of difference exceeds the normal range. This difference threshold can be set according to the equipment specifications and usage conditions.

[0087] Optionally, if the difference between the actual irradiation dose and the expected irradiation dose exceeds the set threshold, the UV module is deemed to be in an abnormal condition, which may indicate that the UV module has experienced performance degradation, light source aging, dirt accumulation, or other malfunctions; if the difference is within the normal range, the UV module is in normal working condition and continues to operate according to the current settings.

[0088] When the usage status of the UV module is determined to be abnormal, an alarm mechanism will be triggered. Alarms can be: visual cues (such as displaying warning messages on the control panel or illuminating warning lights), audible cues (such as issuing alarm sounds or beeps), digital alarms, etc. (such as sending alarm information to maintenance personnel or users via SMS, email, etc.).

[0089] In one embodiment, by monitoring the difference between the actual irradiation dose and the expected irradiation dose, abnormalities in the UV module can be detected in a timely manner, avoiding potential water quality problems or equipment failures. Furthermore, abnormal alarms can prompt maintenance personnel to promptly inspect and maintain the UV module, preventing the fault from worsening and reducing the occurrence of sudden failures. All of these factors help ensure that the UV module consistently and effectively disinfects the water, avoiding water quality safety hazards caused by equipment malfunctions.

[0090] Optionally, the usage status includes the remaining lifespan of the UV module; the abnormal usage status includes the remaining lifespan being below a critical value.

[0091] The remaining lifespan of a UV module can be determined by the difference between the actual and expected irradiation dose (a large difference usually indicates aging of the UV module's light source or other problems, resulting in a lower-than-expected irradiation dose). If the remaining lifespan is detected to be below a critical value, a corresponding alarm can be issued to prompt the user to replace the module in a timely manner.

[0092] In one embodiment, based on the above embodiments, referring to Figure 2 The cavity is a truncated cone (the truncated cone is hollow), and the water outlet direction is from the bottom of the truncated cone to the top of the truncated cone.

[0093] The UV module is located inside the frustum.

[0094] The frustum shape helps to evenly distribute water flow within the chamber, ensuring that UV light can more evenly irradiate all parts of the water flow. This design helps improve sterilization effectiveness because every part of the water receives sufficient UV radiation. Furthermore, the frustum shape increases the residence time of the water within the chamber, increasing the contact time between the water and the UV light source. This contributes to improved sterilization efficiency, as longer UV light exposure generally results in better sterilization. Simultaneously, the frustum shape reduces abrupt changes in water flow within the chamber, minimizing mechanical wear on internal components. This helps extend the lifespan of the UV module and other related accessories.

[0095] Optionally, if the cavity before the faucet outlet is a frustum, the formula for calculating the expected irradiation dose is as follows:

[0096] G1 = P / V × h / v;

[0097] Wherein, P is the sterilization power, V is the volume of the frustum, h is the height of the frustum, and v is the water flow rate.

[0098] Where, V = 1 / 3πh(r) 2 +R 2 +rR), where r is the radius of the platform and R is the radius of the base.

[0099] Furthermore, this application embodiment also provides an electronic control device, the internal architecture of which can be as follows: Figure 3 As shown, the system includes a processor, memory, communication interface, and input interface connected via a system bus. The processor provides computing and control capabilities. The memory includes a non-volatile storage medium and internal memory. The non-volatile storage medium stores an operating system, computer programs, and a database. The internal memory provides an environment for the operation of the operating system and computer programs in the non-volatile storage medium. The database stores data called by the computer programs. The communication interface is used for data communication with external terminals. The input interface is used to receive signals from external devices. When the computer program is executed by the processor, it implements a faucet sterilization method as described in the above embodiment.

For example, in some optional embodiments, the electronic control device may further include an output interface (not shown in the figure), and the output interface is also connected to the system bus and used to output corresponding signals to peripherals.

[0101] Furthermore, this application also proposes a sterilizing faucet, which includes: a UV module, an irradiation intensity sensor, a flow sensor, and an electronic control device; see reference. Figure 4 The UV module and the irradiance sensor are located in the cavity before the faucet outlet (the UV module and the irradiance sensor can be integrated into the UV and irradiance sensor module, and the UV and irradiance sensor module can be located in the cavity before the faucet outlet). The flow sensor is located in the faucet inlet pipe. The electronic control device is located in the structural part outside the faucet water flow channel (i.e., the channel between the inlet pipe and the faucet outlet where water can flow). The UV module, the irradiance sensor, and the flow sensor are all electrically connected to the electronic control device (not shown in the figure).

[0103] In summary, the faucet sterilization method, control device, electronic control device, and computer-readable storage medium provided in this application embodiment automatically adjust the sterilization power of the UV module based on the actual detected water flow and irradiation intensity. This ensures that the sterilization effect is maintained under different usage conditions while avoiding unnecessary energy waste, thus improving the sterilization efficiency of the faucet and making the use of the sterilizing faucet more environmentally friendly. Furthermore, real-time monitoring and adjustment of the irradiation dose enables precise control of the irradiation intensity and dose, ensuring that bacteria and pathogens in the water are fully eliminated, thereby enhancing the safety of drinking water.
