[0002] As living standards gradually improve, people have increasingly stringent requirements for drinking water quality, and water purification equipment has become commonplace in daily life. During the use of water purification equipment, as the water production increases, impurities accumulated inside the filter element can contaminate the filter screen. To ensure the health of users' drinking water, the filter element needs to be rinsed.

[0003] When existing water purification equipment flushes the filter cartridge, users need to manually click the flush button of the water purification equipment according to their own needs, or set a timed flush, that is, when the water production (or water production time) of the water purification equipment exceeds the preset value, the automatic flushing operation of the filter cartridge is triggered.

[0004] The above-mentioned methods of rinsing the filter element have the problem of not rinsing in time, which can affect the service life of the filter element and reduce the user's water experience. Summary of the Invention

It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0052] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0053] Figure 1 This is a schematic flowchart of the filter cartridge rinsing method provided by the present invention. This embodiment is applicable to the automatic rinsing of filter cartridges in water purification equipment. The method can be executed by a filter cartridge rinsing device, which can be implemented in hardware and / or software and can be configured in the water purification equipment. (Reference) Figure 1 The method may specifically include the following steps:

[0054] S110. Obtain the location information of the water purification equipment, and determine the temperature and water quality information of the area where the water purification equipment is located based on the location information.

[0055] The water purification equipment mentioned in this embodiment can be a small household water purifier used to provide purified domestic water for users' families, or it can be a water purifier installed in a fixed area (such as a residential community, shopping mall or school) to provide drinking water. The specific type of water purification equipment is not limited here.

[0056] When obtaining the location information of water purification equipment, a positioning module can be installed in the water purification equipment to obtain the location information. In specific applications, the location information of each water purification device can be obtained through a server, or the microcontroller unit (MCU) in the water purification device can obtain the location information based on the positioning module. The specific execution entity of this solution is not limited here.

[0057] The current location information can be the location of the water purification equipment, such as the province, city, county (or district), etc., and further, the temperature and water quality information of the area where the water purification equipment is located can be determined based on the current location information.

[0058] The temperature information mentioned above can be the outdoor ambient temperature of the water purifier's location obtained through the network module, or the indoor temperature of the water purifier's location obtained through a temperature sensor. The purpose of obtaining temperature information is that the water production capacity of the water purifier is affected by air temperature. Under the same inlet water pressure and flow rate, lower temperatures result in less purified water and more wastewater; conversely, higher temperatures result in a relatively higher purified water volume and less wastewater. Therefore, with increased purified water volume, the filter cartridge needs to be used more frequently, requiring more frequent rinsing at higher temperatures. Additionally, at higher temperatures, more frequent rinsing is also necessary to prevent impurities in the filter cartridge from causing odors.

[0059] Current water quality information can be obtained from the water quality sensors installed in the water purification equipment; alternatively, it can be obtained by the equipment manufacturer's personnel maintaining the water quality database. The purpose of obtaining water quality information is to ensure that the worse the water quality, the more impurities the filter cartridge will filter, requiring more frequent rinsing of the filter cartridge.

[0060] Specifically, when water quality information is obtained through water quality sensors, the incoming water quality can be tested once at preset time intervals, such as once a day or once a week. When water quality information is obtained through maintenance of the water quality database by the equipment manufacturer's corresponding staff, the specific method can be as follows: for the same area, there may be multiple users who have purchased the current water purification equipment at different time periods. When the staff installs the water purification equipment for any user, the water quality information of the current user's area can be measured and recorded in the water quality information database. When the water quality information of the same area is different, the latest updated information shall prevail. The water quality values ​​that can be measured in the current water quality information are divided into: poor, fair, good, and excellent. The specific method of water quality information division is not limited here.

[0061] S120. Determine the current flushing cycle of the water purification equipment based on temperature and water quality information.

[0062] The current flushing cycle can be understood as the interval at which the filter element is flushed under the influence of current temperature and water quality information. Optionally, when the temperature and water quality information are different, the flushing frequency and duration for each flush of the filter element will also be different, so as to ensure thorough flushing based on the actual usage of the filter element.

[0063] Optionally, the current flushing cycle of the water purifier can be determined based on temperature and water quality information by determining a water production threshold based on current water quality information and a flushing frequency and duration based on temperature information. When the water production of the water purifier reaches the current water production threshold, the filter element is flushed based on a predetermined flushing frequency and duration.

[0064] Generally, the higher the temperature and the worse the water quality, the shorter the rinsing cycle, meaning that the filter element is rinsed more frequently, and the rinsing process is longer and more frequent. Conversely, the lower the temperature and the better the water quality, the longer the rinsing cycle, meaning that the filter element is rinsed less frequently, and the rinsing process is shorter and less frequent.

[0065] One possible scenario is that in practical applications, there may be situations where the temperature is low and the water quality is poor, or the temperature is high and the water quality is good. In this case, it is necessary to determine the corresponding influencing factors for the temperature and water quality information, such as temperature influencing factors and water quality influencing factors, and assign different weight information to the temperature influencing factors and water quality influencing factors, so as to comprehensively determine the current flushing cycle, etc.

[0066] S130. Rinse the filter element of the water purification equipment according to the current rinsing cycle.

[0067] When rinsing the filter element according to the current rinsing cycle determined by the above steps S110~S120, the determined rinsing cycle will be dynamically adjusted according to changes in temperature or water quality information, so that rinsing can be automatically triggered when the filter element meets the rinsing conditions under different temperature or water quality conditions.

[0068] The filter cartridge flushing method provided in this embodiment first obtains the location information of the water purification equipment, then determines the temperature and water quality information of the area where the water purification equipment is located based on the location information; next, it determines the current flushing cycle of the water purification equipment based on the temperature and water quality information; finally, it flushes the filter cartridge of the water purification equipment according to the current flushing cycle. This embodiment dynamically adjusts the flushing cycle of the filter cartridge by using the temperature and water quality information of the area where the water purification equipment is located, enabling timely flushing of the filter cartridge according to the actual usage of the water purification equipment. Compared with existing methods of timed or manual flushing of filter cartridges, this method effectively protects the filter cartridge, extends its service life, and improves the user's water experience.

[0069] Figure 2 This is another schematic flowchart of the filter element rinsing method provided by the present invention. The relationship between this embodiment and the above embodiments further refines the corresponding features of the above embodiments. Figure 2 As shown, the method may include the following steps:

[0070] S210. Obtain the equipment status of the water purification equipment.

[0071] The device status is indicated by the user to indicate the network connection status of the water purification device. In the solution provided in this embodiment, the device status includes network connection status and non-network connection status.

[0072] When the water purification equipment is connected to the network, it can communicate with the server, or the controller in the equipment can acquire, report and analyze data from other modules (such as temperature measurement module, water quality detection module, etc.) to more intelligently determine the rinsing method of the filter cartridge. When the water purification equipment is not connected to the network, the filter cartridge needs to be rinsed by timed (when the water production time exceeds a certain threshold) or quantitative (when the water production volume exceeds a certain threshold).

[0073] S220. Determine whether the device is in a network connection state.

[0074] If the device is connected to the network, proceed to step S230; if it is not connected to the network, proceed to step S290.

[0075] S230. Obtain the location information of the water purification equipment, and determine the temperature and water quality information of the area where the water purification equipment is located based on the location information.

[0076] S240. Determine the target temperature range corresponding to the temperature information in the first relationship table.

[0077] The first relation table includes at least two temperature ranges. For example, if the first relation table contains six temperature ranges, they can be divided according to the temperature in the four seasons into ranges such as less than 10℃, (10℃, 18℃), (18℃, 22℃), (22℃, 25℃), (25℃, 30℃), and greater than 30℃. The specific method and number of temperature ranges in the first relation table are not limited to the above example.

[0078] When determining the target temperature range corresponding to the temperature information in the first relationship table, the temperature range containing the current temperature information value is used as the target temperature range. For example, if the current temperature information is 28℃, the corresponding target temperature range is (25℃, 30℃).

[0079] S250. Determine the target water quality level corresponding to the water quality information in the second relationship table.

[0080] The second relationship table includes at least two water quality grades. For example, it can be divided into four grades based on different measured water quality values, such as poor, fair, good, and excellent. The specific water quality values ​​corresponding to each grade are not limited here.

[0081] When determining the target water quality level corresponding to the water quality information in the second relationship table, the water quality level containing the current water quality value will be used as the target water quality level.

[0082] Furthermore, the current flushing cycle can be determined based on the target temperature range and the target water quality level.

[0083] The filter cartridge flushing scheme provided in this embodiment includes a flushing cycle comprising a flushing frequency and a flushing duration; in the first relationship table, a temperature range corresponds to a flushing frequency and a flushing duration; in the second relationship table, a water quality grade corresponds to a water production capacity. Specifically, the method of determining the current flushing cycle based on the target temperature range and the target water quality grade can be implemented by steps S260~S280.

[0084] S260. Determine the corresponding target flushing frequency and target flushing duration based on the target temperature range in the first relationship table.

[0085] Before determining the target flushing frequency and target flushing duration based on the target temperature range in the first relationship table, it is necessary to first determine the flushing frequency and flushing duration corresponding to each temperature range. This can be achieved through the following steps a) to c):

[0086] a) Determine the standard flushing frequency and standard flushing duration corresponding to the standard temperature range, and determine the frequency influence factor and duration influence factor corresponding to each temperature range; b) Determine the flushing frequency corresponding to each temperature range based on the standard flushing frequency and each frequency influence factor; c) Determine the flushing duration corresponding to each temperature range based on the standard flushing duration and each duration influence factor.

[0087] Taking the division of temperature into six temperature ranges in step S240 above—less than 10℃, (10℃, 18℃), (18℃, 22℃), (22℃, 25℃), (25℃, 30℃), and greater than 30℃—as an example, the temperature range containing (18℃, 22℃) can be defined as the standard temperature range. The standard rinsing frequency and standard rinsing duration corresponding to the current standard temperature range can be determined using... and The frequency influence factor is represented by 'a', and the duration influence factor is represented by 'b'. In the standard flushing frequency and standard flushing duration corresponding to the standard temperature range, the frequency influence factor corresponding to the standard flushing frequency takes the value of 1; the duration influence factor corresponding to the standard flushing duration also takes the value of 1.

[0088] Furthermore, the higher the temperature, the larger the values ​​of the frequency influence factor and duration influence factor corresponding to each temperature range; conversely, the lower the temperature, the lower the values ​​of the frequency influence factor and duration influence factor corresponding to each temperature range. Optionally, the range of the frequency influence factor and duration influence factor provided in this embodiment can be [0.8, 1.2]. For example, the values ​​of frequency influence factor a and duration influence factor b corresponding to (18℃, 22℃) can be 1; the values ​​of frequency influence factor a and duration influence factor b corresponding to (22℃, 25℃) can be 1.1; the values ​​of frequency influence factor a and duration influence factor b corresponding to temperatures above 30℃ can be 1.2; the values ​​of frequency influence factor a and duration influence factor b corresponding to (10℃, 18℃) can be 0.9; and the values ​​of frequency influence factor a and duration influence factor b corresponding to temperatures below 10℃ can be 0.8, etc. The specific range of values ​​for frequency influence factor a and duration influence factor b, as well as the specific values ​​of frequency influence factor a and duration influence factor b corresponding to each temperature range, are not limited here.

[0089] The standard flushing frequency multiplied by each frequency influence factor results in the flushing frequency corresponding to each temperature range. The standard flushing duration multiplied by each duration influence factor results in the flushing frequency corresponding to each temperature range.

[0090] Through the above steps a) to c), a first relationship table can be obtained, and the target flushing frequency and target flushing duration corresponding to the target temperature range can be further determined in the first relationship table.

[0091] S270. Determine the corresponding target water production volume based on the target water quality level in the second relationship table.

[0092] Before determining the target water production volume based on the target water quality level in the second relationship table, it is first necessary to determine the water production volume corresponding to each water quality level. This can be achieved through the following steps d) and e):

[0093] d) Determine the standard water production volume corresponding to the standard water quality grade, and determine the water quality influencing factor corresponding to each water quality grade; e) Determine the water production volume corresponding to each water quality grade based on the standard water production volume and each water quality influencing factor.

[0094] Taking the above step S250, which divides water quality into poor, average, good, and excellent grades, as an example, the water quality grade of good can be defined as the standard water quality grade. Under the standard water quality grade, the corresponding water production volume can be X liters. Therefore, the higher the water quality grade, the greater the corresponding water production volume, i.e., greater than X; the lower the water quality grade, the lower the corresponding water production volume, i.e., less than X.

[0095] The water quality impact factor provided in this embodiment can be [0.6, 1.2]. Under the standard water production capacity corresponding to the standard water quality grade, the water quality impact factor is 1. Optionally, when the water quality grade is excellent, the corresponding water quality impact factor can be 1.2; when the water quality grade is average, the corresponding water quality impact factor can be 0.8; when the water quality grade is poor, the corresponding water quality impact factor can be 0.6. The specific range of water quality impact factor values, and the specific values ​​of water quality impact factors corresponding to each water quality grade are not limited here.

[0096] The standard water production volume multiplied by each water quality influencing factor results in the water production volume corresponding to each water quality level.

[0097] The second relationship table can be obtained through steps d) and e) above. The target water quality level can be determined from the second relationship table to determine the corresponding target water production volume.

[0098] S280. When the water production of the water purification equipment reaches the target water production, control the filter element to be flushed based on the target flushing frequency and target flushing duration.

[0099] In the current step, the water production of the water purification equipment is monitored. When the target water production is reached, the filter element is flushed based on the target flushing frequency and target flushing duration. After flushing is completed, step S210 is repeated to adjust the flushing cycle according to the obtained actual temperature and water quality information, so as to flush the filter element according to the dynamic cycle.

[0100] S290, The filter element is rinsed using a preset method.

[0101] When the water purification equipment is offline, it still needs to be flushed. The solution provided in this embodiment can be based on a preset method for flushing. Specifically, the preset method for flushing the filter element is achieved as follows:

[0102] Obtain the offline water production of the water purifier; when the offline water production reaches the preset value, flush the filter cartridge.

[0103] Offline water production refers to the amount of water produced by the device when it is not connected to the network. The current water production can be obtained by calculating the number of gallons produced and the duration of water production by the water purifier. When the offline water production reaches a preset value, the filter cartridge will be flushed.

[0104] The aforementioned preset values ​​are obtained by acquiring historical temperature and water quality information of the water purifier when it is connected to the network. When the historical temperature and water quality information contain multiple levels, the preset values ​​are determined based on the historical temperature information of the highest level and the historical water quality information of the lowest level.

[0105] For example, if the historical temperature information corresponds to two temperature ranges (10℃, 18℃] and (22℃, 25℃], and the historical water quality information corresponds to two water quality grades (general and excellent), then preset values ​​are determined based on (10℃, 18℃] and the water quality grade (general) to account for situations where the filter cartridge has not been flushed for a long time while offline.

[0106] The filter cartridge flushing method provided in this embodiment determines the target flushing cycle and target water production capacity. When the water purification equipment reaches the target water production capacity, it controls the flushing of the filter cartridge based on the target flushing frequency and duration. This allows the filter cartridge flushing cycle to change according to actual environmental changes, achieving timely flushing and protecting the filter cartridge. It also prevents odors in the effluent under high-temperature environments and personalizes the flushing cycle according to the water quality conditions of different areas, thus protecting the filter cartridge and ensuring the user's drinking water health.
