Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments.

[0052] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0053] Figure 1 This is a flow chart of the filter element flushing method provided by the present invention. This embodiment is applicable to the case of automatically flushing the filter element of a water purification device. The method can be performed by a filter element flushing device. The device can be implemented in the form of hardware and / or software. The device can be configured in a water purification device. Figure 1 , the method may specifically include the following steps:

[0054] S110. Acquire location information of the water purification equipment, and determine temperature information and water quality information of the area where the water purification equipment is located according to the location information.

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

[0056] When obtaining the location information of the water purification device, a positioning module may be provided in the water purification device to obtain the location information of the water purification device through the positioning module. In particular, when this solution is applied, the location information of each water purification device may be obtained through a server, or the microcontroller unit (MCU) in the water purification device may obtain the location information based on the positioning module. The specific execution subject of this solution is not limited here.

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

[0058] The above-mentioned temperature information can be the outdoor ambient temperature of the location where the water purification equipment is located obtained based on the networking module; it can also be the indoor temperature of the location where the water purification equipment is located obtained by the temperature sensor, etc. The purpose of obtaining temperature information is that the water production of the water purification equipment is affected by the temperature. Under the same water inlet pressure and water inlet volume, the amount of purified water decreases when the temperature is low, the purified water is less, and the waste water increases; Conversely, when the temperature is high, the amount of purified water increases relatively, and the waste water decreases. Therefore, when the amount of purified water increases, the number of times the filter element is used increases relatively, so when the temperature is high, the filter element needs to be rinsed more frequently. At the same time, under high temperature conditions, in order to prevent impurities in the filter element from producing odors, the filter element also needs to be rinsed more frequently.

[0059] The current water quality information can be obtained by the water quality sensor installed in the water purification equipment; it can also be obtained by the corresponding staff of the equipment manufacturer after maintaining the information in the water quality database. The purpose of obtaining water quality information is that when the water quality is worse, the filter element will filter more impurities and need to be flushed more frequently.

[0060] Among them, when the water quality information is obtained through a water quality sensor, the incoming water quality can be detected once every preset time period, such as one day or one week; when the water quality information is obtained through the maintenance of the information in the water quality database by the corresponding staff of the equipment manufacturer, the specific method can be that for the same area, there may be multiple users who purchase the current water purification equipment in different time periods. When the staff installs the water purification equipment for any user, the water quality information of the area where the current user is located can be measured and recorded in the water quality information database. When the water quality information in the same area is different, the latest update shall prevail. Among them, the water quality values ​​that can be measured by the current water quality information are divided into: poor, general, good, excellent, etc., and the specific way of dividing the water quality information is not restricted here.

[0061] S120. Determine the current flushing cycle of the water purification device according to the temperature information and the 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 the current temperature information and water quality information. Optionally, when the temperature information and water quality information are different, the flushing frequency and flushing duration corresponding to each flushing of the filter element are also different, so as to thoroughly flush the filter element according to the actual use of the filter element.

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

[0064] Generally speaking, when the temperature is higher and the water quality is worse, the flushing cycle is shorter, that is, the filter element is flushed more frequently, and during the flushing process, the flushing time is longer and the frequency is higher; conversely, when the temperature is lower and the water quality is better, the flushing cycle is longer, that is, the filter element is flushed less frequently, and during the flushing process, the flushing time is shorter and the frequency is lower.

[0065] A possible situation is that in actual application, the temperature may be low and the water quality may be poor, or the temperature may be high and the water quality may be good. At this time, the corresponding influencing factors need to be determined for the temperature information and the water quality information, such as the temperature influencing factor and the water quality influencing factor, and different weight information is assigned to the temperature influencing factor and the water quality influencing factor, so as to comprehensively determine the current flushing cycle, etc.

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

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

[0068] The filter element flushing method provided in this embodiment first obtains the location information of the water purification equipment, then determines the temperature information and water quality information of the area where the water purification equipment is located based on the location information; then determines the current flushing cycle of the water purification equipment based on the temperature information and water quality information; and finally flushes the filter element of the water purification equipment based on the current flushing cycle. This embodiment dynamically adjusts the flushing cycle of the filter element through the temperature information and water quality information of the area where the water purification equipment is located, and can flush the filter element in time according to the actual use of the water purification equipment. Compared with the existing method of timed or manual flushing of the filter element, it has the beneficial effect of effectively protecting the filter element, extending the service life of the filter element, and improving the user's water experience.

[0069] Figure 2 1 is another schematic flow chart of the filter element flushing method provided by the present invention. The relationship between this embodiment and the above embodiment is a further refinement of the corresponding features of the above embodiment. Figure 2 As shown, the method may include the following steps:

[0070] S210, obtaining the equipment status of the water purification equipment.

[0071] The device status user indicates the networking status of the water purification device. In the solution provided in this embodiment, the device status includes the networking status and the non-networking status.

[0072] When the water purification equipment is in an online state, the water purification equipment can communicate with the server, or the controller in the water purification equipment can acquire, report and analyze corresponding data information with other modules (such as temperature measurement module, water quality detection module, etc.), so as to more intelligently determine the flushing method of the filter element; when the water purification equipment is not in an online state, the filter element must be flushed in a timed (water production time exceeds a certain threshold) or quantitative (water production volume exceeds a certain threshold) manner.

[0073] S220: Determine whether the device status is in a networked state.

[0074] If it is in the networking state, execute step S230; if it is not in the networking state, that is, in the non-networking state, execute step S290.

[0075] S230: Acquire location information of the water purification equipment, and determine temperature information and water quality information of the area where the water purification equipment is located according to the location information.

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

[0077] The first relationship table includes at least two temperature intervals. For example, taking the first relationship table including six temperature intervals as an example, the temperature intervals can be divided into less than 10°C, (10°C, 18°C], (18°C, 22°C], (22°C, 25°C], (25°C, 30°C], greater than 30°C, etc. according to the temperature in the four seasons of the year. The specific division method and number of temperature intervals in the first relationship table are not limited to the above examples.

[0078] When determining the target temperature interval corresponding to the temperature information in the first relationship table, the temperature interval corresponding to the current temperature information value is taken as the target temperature interval. For example, if the current temperature information is 28° C., the corresponding target temperature interval is (25° C., 30° C.).

[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 levels. For example, the water quality values ​​measured can be divided into four levels, such as poor, general, good, and excellent, and the specific water quality value corresponding to each level is 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 corresponding to the current water quality value is included as the target water quality level.

[0082] Furthermore, the current flushing cycle may be determined according to the target temperature range and the target water quality level.

[0083] The filter element flushing scheme provided in this embodiment includes a flushing cycle including 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 level corresponds to a water production volume. Specifically, the method of determining the current flushing cycle according to the target temperature range and the target water quality level can be implemented by steps S260 to S280.

[0084] S260 . Determine a corresponding target flushing frequency and a target flushing duration according to the target temperature range in the first relationship table.

[0085] Before determining the corresponding target flushing frequency and target flushing duration according to the target temperature interval in the first relationship table, it is necessary to first determine the flushing frequency and flushing duration corresponding to each temperature interval, which can be specifically achieved by the following steps a) to c):

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

[0087] Taking the above step S240 in which the temperature is divided into six temperature intervals of less than 10°C, (10°C, 18°C], (18°C, 22°C], (22°C, 25°C], (25°C, 30°C], and greater than 30°C as an example, the temperature interval where (18°C, 22°C] is located can be determined as the standard temperature interval, and the standard flushing frequency and standard flushing time corresponding to the current standard temperature interval can be represented by f0 and t0. The frequency influence factor is represented by a, and the time influence factor is represented by b. In the standard flushing frequency and standard flushing time corresponding to the standard temperature interval, the frequency influence factor corresponding to the standard flushing frequency is 1; the time influence factor corresponding to the standard flushing time is also 1.

[0088] Furthermore, when the temperature is higher, the frequency impact factor and duration impact factor corresponding to each temperature interval have larger values, and when the temperature is lower, the frequency impact factor and duration impact factor corresponding to each temperature interval have lower values. Optionally, the frequency impact factor and duration impact factor provided in this embodiment may have a value range of [0.8, 1.2]. Exemplarily, for (18°C, 22°C], the values ​​of the frequency impact factor a and the duration impact factor b corresponding to [18°C, 22°C] can be 1; the values ​​of the frequency impact factor a and the duration impact factor b corresponding to [22°C, 25°C] can be 1.1; the values ​​of the frequency impact factor a and the duration impact factor b corresponding to greater than 30°C can be 1.2; the values ​​of the frequency impact factor a and the duration impact factor b corresponding to [10°C, 18°C] can be 0.9; the values ​​of the frequency impact factor a and the duration impact factor b corresponding to less than 10°C can be 0.8, etc. The specific value ranges of the frequency impact factor a and the duration impact factor b, and the specific values ​​of the frequency impact factor a and the duration impact factor b corresponding to each temperature interval are not limited here.

[0089] The standard flushing frequency multiplied by each frequency influencing factor is the flushing frequency corresponding to each temperature range. The standard flushing duration multiplied by each duration influencing factor is 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 amount according to the target water quality level in the second relationship table.

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

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

[0094] Taking the above step S250 to divide the water quality levels into poor, general, good, and excellent as an example, the water quality level of good can be determined as the standard water quality level. Under the standard water quality level, the corresponding water production can be X liters. Then, when the water quality level is higher, the corresponding water production is larger, that is, greater than X; when the water quality level is lower, the corresponding water production is reduced, that is, less than X.

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

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

[0097] Through the above steps d) and e), a second relationship table can be obtained, and the target water quality level can be further determined in 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 flushing of the filter element based on the target flushing frequency and the target flushing time.

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

[0100] S290, flush the filter element in a preset manner.

[0101] When the water purification device is in an offline state, it is necessary to flush the water purification device in the offline state. The solution provided in this embodiment can be flushed based on a preset method. Specifically, flushing the filter element in a preset manner is achieved as follows:

[0102] Obtain the offline water production of the water purification equipment; when the offline water production reaches a preset value, flush the filter element.

[0103] The offline water production is the water production when the equipment is not connected to the Internet. The current water production can be obtained by obtaining the offline water production based on the number of gallons of water produced by the water purification equipment and the water production time, so as to start the flushing operation of the filter element when the offline water production reaches a preset value.

[0104] The preset value is obtained by obtaining the historical temperature information and historical water quality information corresponding to the water purification device in the networked state. When the historical temperature information and historical water quality information contain multiple levels, the preset value is determined according to the historical temperature information of the highest level and the historical water quality information of the lowest level.

[0105] Exemplarily, when the temperature intervals corresponding to the historical temperature information include two temperature intervals of (10°C, 18°C] and (22°C, 25°C], and the water quality levels corresponding to the historical water quality information include general and excellent, the preset value is determined based on (10°C, 18°C] and the water quality level is general, etc., to prevent the filter element from being flushed for a long time in the offline state.

[0106] The filter element flushing method provided in this embodiment determines the target flushing cycle and the target water production, so that when the water production of the water purification equipment reaches the target water production, the filter element is flushed based on the target flushing frequency and the target flushing duration. The flushing cycle of the filter element is changed according to the changes in the actual environment, so that the filter element is flushed in time to protect the filter element. It also prevents the output water from having odor in a high temperature environment, and customizes the flushing cycle according to the water quality conditions in different regions, so as to protect the filter element and ensure the health of the user's drinking water.
