Description

Technical Field

[0001] The present application relates to the field of water treatment, and in particular, to a water purification pipeline and a control method. Background Art

[0002] With the development of technology, water purification devices have appeared on the market, which can purify some pollutants in water to obtain clean water. Users usually use clean water for activities such as washing vegetables.

[0003] The core components of current water purification devices are ultrafiltration membranes, PP cotton, activated carbon and other filter components. As the water purification device is used, rust, sand and other particles will accumulate in the filter components, resulting in a decrease in the filtering effect of the filter components. Users need to replace the filter components more frequently, which reduces the user experience. Summary of the invention

[0004] The embodiments of the present application provide a water purification pipeline and a control method to at least solve the technical problem of reduced user experience.

[0005] According to a first aspect of an embodiment of the present application, a water purification pipeline is provided, the water purification pipeline comprising:

[0006] A first branch pipeline, the water inlet end of which is used to flow in a type of raw water, and the water outlet end of which is connected to the water inlet end of the main pipeline, and a first valve for opening and closing is arranged on the first branch pipeline;

[0007] The second branch pipeline has a water inlet end for inflow of Class II raw water, and a water outlet end connected to the water inlet end of the main pipeline. The second branch pipeline is provided with a second valve for on-off function and a cleaner for cleaning the filter element;

[0008] A main pipeline, the water inlet end of which is respectively connected with the water outlet end of the first branch pipeline and the water outlet end of the second branch pipeline, the main pipeline is provided with a water tap and a filter element for filtering the first type of raw water and / or the second type of raw water, and the filter element is located between the water tap and the water inlet end of the main pipeline;

[0009] The water intake faucet has an open state that allows the water in the main line to be discharged from the water intake faucet, and a closed state that does not allow the water in the main line to be discharged from the water intake faucet.

[0010] In this embodiment, a cleaner is provided on the second branch pipe, so that when the second branch pipe is used or the cleaner is turned on, the filter element can be cleaned by the cleaner, so that the service life of the filter element is extended, the replacement frequency of the filter element is reduced, and the user experience is improved. In addition, since the first branch pipe is used to flow in type I raw water and the second branch pipe is used to flow in type II raw water, the water purification pipeline can provide two types of raw water for the user, which is easier to meet the user's use needs and improves the user experience.

[0011] In combination with the first aspect, in an optional implementation of the embodiment of the present application, a detector is provided between the water inlet end of the main pipeline and the water tap, and the detector is used to detect the cleaning requirement of the filter element;

[0012] When the detector detects that the filter element needs to be cleaned, the second valve is controlled to open so that the second type of raw water passes through the cleaner and enters the filter element to clean the filter element.

[0013] By adopting this implementation method, a detector is set up so that the detector can automatically detect the need for cleaning the filter element and automatically clean the filter element when there is a need for cleaning, thereby improving the automation level of filter element cleaning, thereby reducing user operations and improving user experience.

[0014] In combination with the first aspect, in an optional implementation of the embodiment of the present application, the detector includes at least one of a flow meter and a water quality probe.

[0015] With this implementation, the flow meter can detect the water flow, so as to timely find out the blockage of the filter element, and the water quality probe can detect the water quality, so as to timely find out the filtering condition of the filter element on the water quality. Both the flow meter and the water quality probe can realize the detection of the cleaning requirement of the filter element.

[0016] In combination with the first aspect, in an optional implementation of the embodiment of the present application, the detector includes a flow meter and a water quality probe, the flow meter is arranged between the water inlet end of the main pipeline and the water tap, and the water quality probe is arranged between the filter element and the water tap;

[0017] The filter element comprises a first water outlet and a second water outlet, and the main pipeline comprises a first water outlet branch and a second water outlet branch;

[0018] The water discharged from the first water outlet flows through the water quality probe and the flow meter in sequence and can be discharged from at least one of the water tap and the first water outlet branch;

[0019] The water discharged from the second water outlet is discharged from the second water outlet branch;

[0020] The first water outlet branch is provided with a third valve, and the second water outlet branch is provided with a fourth valve.

[0021] With this implementation, by setting the first water outlet and the second water outlet, when different impurities in the filter element need to be cleaned, water flows out from different water outlets of the filter element, which is conducive to improving the cleaning effect of the filter element. In addition, the main line includes a first water outlet branch and a second water outlet branch, and both water outlet branches are used for drainage when cleaning the filter element, so that the water tap is not easily contaminated, improving the user experience.

[0022] In combination with the first aspect, in an optional implementation of the embodiment of the present application, the filter element includes at least one of an ultrafiltration membrane, PP cotton, activated carbon and a carbon rod;

[0023] The clean water pipeline is configured as follows:

[0024] When the ultrafiltration membrane and / or PP cotton needs to be cleaned, the cleaning water is discharged from the second water outlet branch; when the activated carbon and / or carbon rod needs to be cleaned, the cleaning water is discharged from the first water outlet branch, wherein the flow meter is used to detect the cleaning needs of the ultrafiltration membrane and / or PP cotton, and the water quality probe is used to detect the cleaning needs of the activated carbon and / or carbon rod.

[0025] By adopting this implementation method, when cleaning different impurities in the filter element, different water outlet branches are used for drainage, which is beneficial to improving the cleaning effect and cleaning efficiency of the filter element and is not easy to pollute the main line.

[0026] In combination with the first aspect, in an optional implementation of the embodiment of the present application, the cleaner includes an ejector.

[0027] By adopting this implementation method, the ejector can increase the number of microbubbles in the water flow. When the water flows through the filter element, the microbubbles will release a certain amount of energy to remove the pollutants in the filter element to achieve the purpose of cleaning, which is beneficial to improving the cleaning effect of the filter element.

[0028] In combination with the first aspect, in an optional implementation of the embodiment of the present application, the first type of raw water is room temperature water, and the second type of raw water is hot water; or, the water inlet end of the first branch pipe is connected to the water outlet of the tap water, and the water inlet end of the second branch pipe is connected to the water outlet of the water heater.

[0029] By adopting this implementation method, both room temperature water and hot water are commonly used water. The water purification pipeline can not only provide users with room temperature purified water, but also provide users with hotter purified water, which is convenient to meet the different usage needs of users and meet the user's demand for hot water in winter, thereby improving the user experience.

[0030] According to a second aspect of an embodiment of the present application, a water purification pipeline control method is provided, which is applied to the water purification pipeline described above, wherein the detector is used to detect the flow value and / or chlorine concentration on the main pipeline, and the method includes:

[0031] If the flow value collected by the detector is lower than a preset flow threshold, the first branch pipeline is controlled to be closed and the second branch pipeline is controlled to provide Class II raw water to clean the filter element;

[0032] And / or, if the chlorine concentration collected by the detector exceeds a preset concentration threshold, the first branch pipeline is controlled to be closed and the second branch pipeline is controlled to provide Class II raw water to clean the filter element.

[0033] By adopting this embodiment, automatic detection of filter element cleaning is achieved using a flow meter and a water quality probe, thereby realizing automatic cleaning, which increases the service life and filtering effect of the filter element. The filter element cleaning process does not require user control, reduces the frequency of user filter element replacement, and improves the user experience.

[0034] In conjunction with the second aspect, in an optional implementation of the embodiment of the present application, applied to the above-mentioned water purification pipeline, the method includes:

[0035] If the flow value collected by the flow meter is lower than the preset flow threshold, the second valve and the fourth valve are controlled to be opened and the water outlet tap is controlled to be closed, so that the second type of raw water passes through the cleaner and is discharged from the second water outlet branch through the second water outlet of the filter element to clean the filter element;

[0036] If the chlorine concentration collected by the water quality probe exceeds the preset concentration threshold, the second valve and the third valve are controlled to open and the water outlet tap is controlled to close, so that the second type of raw water passes through the cleaner and is discharged from the first water outlet branch through the first water outlet of the filter element to clean the filter element.

[0037] By adopting this embodiment, automatic detection of filter element cleaning is achieved using a flow meter and a water quality probe, thereby realizing automatic cleaning, which increases the service life and filtering effect of the filter element. The filter element cleaning process does not require user control, reduces the frequency of user filter element replacement, and improves the user experience.

[0038] In conjunction with the second aspect, in an optional implementation of the embodiment of the present application, the method further includes:

[0039] When the second valve and the fourth valve are opened for a first preset time, the filter element is soaked with Class II raw water, and after soaking, the filter element is rinsed with Class I raw water and the water is discharged from the second water outlet branch;

[0040] When the second valve and the third valve are opened for a preset second time period, the filter element is soaked in Class II raw water and then rinsed with Class I raw water and drained from the first water outlet branch.

[0041] When the present implementation method is used to clean the filter element, not only Class II raw water is used for cleaning, but also Class I raw water is used for soaking and final rinsing, which improves the cleaning effect of the filter element and helps to improve the cleanliness of the water purification pipeline.

[0042] In combination with the second aspect, in an optional implementation of the embodiment of the present application, soaking the filter element with the second type of raw water and then flushing the filter element with the first type of raw water and draining the water through the second water outlet branch includes:

[0043] Close the second valve and the fourth valve and, after a preset third time period, open the first valve and the fourth valve;

[0044] The method of soaking the filter element with the second type of raw water and then flushing the filter element with the first type of raw water and draining the water through the first water outlet branch includes:

[0045] The second valve and the third valve are closed and opened after a preset fourth time period.

[0046] By adopting this implementation method, the filter element can be immersed and flushed by controlling the opening and closing states of different valves. The control process is simple, and it is easy to improve the cleaning effect of the filter element and reduce the cleaning cost.

[0047] In conjunction with the second aspect, in an optional implementation of the embodiment of the present application, the method further includes:

[0048] When the filter element needs to be cleaned, the cleaning time is the preset target time period of the next day.

[0049] By adopting this implementation method, by setting a preset target time period, the cleaning process of the filter element is not likely to affect the user's normal use of purified water, thereby improving the user's experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or apparatus.

[0057] With the development of technology, water purification devices have appeared on the market, which can purify some pollutants in water to obtain clean water. Users usually use clean water for activities such as washing vegetables.

[0058] The core components of current water purification devices are ultrafiltration membranes, PP cotton, activated carbon and other filter components. As the water purification device is used, rust, sand and other particles will accumulate in the filter components, resulting in a decrease in the filtering effect of the filter components. Users need to replace the filter components more frequently, which reduces the user experience.

[0059] Based on this, the embodiment of the present application provides a water purification pipeline and a control method. By utilizing household hot water (for bathing, washing face, etc.), only a hot water connection pipeline system is added to achieve water purification for both room temperature water and hot water, solving the problem of cold hands when washing vegetables in winter. In addition, a new hot water pipeline with an ejector is added to perform thermal regeneration treatment on the pretreatment including ultrafiltration membrane or PP cotton and activated carbon under the flow rate and residual chlorine indication value. By controlling the regeneration logic, the life of the entire pretreatment is improved, solving the problem of frequent core replacement in the pretreatment.

[0060] Reference Figure 1 The structural schematic diagram of the water purification pipeline is shown, and the water purification pipeline includes the following contents.

[0061] The first branch pipeline 1 has a water inlet end for inflow of a type of raw water, and a water outlet end connected to the water inlet end of the main pipeline 3. The first branch pipeline 1 is provided with a first valve 11 for on-off function;

[0062] The second branch pipeline 2 has a water inlet end for flowing in the second type of raw water, and a water outlet end connected to the water inlet end of the main pipeline 3. The second branch pipeline 2 is provided with a second valve 21 for opening and closing and a cleaner 22 for cleaning the filter element 31;

[0063] A main pipeline 3, the water inlet end of which is respectively connected with the water outlet end of the first branch pipeline 1 and the water outlet end of the second branch pipeline 2, and the main pipeline 3 is provided with a water tap 4 and a filter element 31 for filtering the first type of raw water and / or the second type of raw water, and the filter element 31 is located between the water tap 4 and the water inlet end of the main pipeline 3;

[0064] The water intake faucet 4 has an open state that allows the water in the main line 3 to be discharged from the water intake faucet 4 and a closed state that does not allow the water in the main line 3 to be discharged from the water intake faucet 4 .

[0065] The first type of raw water and the second type of raw water are different water, which may be different in temperature, different in source, or different in water quality, which is not specifically limited in this embodiment. Preferably, the first type of raw water and the second type of raw water are water with different temperatures. In an application scenario, the first type of raw water is tap water, and the second type of raw water is hot water provided by a heater.

[0066] In one embodiment, the filter element 31 can filter raw water, thereby filtering the raw water into purified water. It should be noted that purified water is different from raw water and pure water. Generally, purified water is understood as water that can be used to wash vegetables and dishes, pure water is water that can be drunk, and raw water is water before filtration.

[0067] In one embodiment, the cleaner 22 is intended to clean the filter element 31. It should be noted that the cleaner 22 is installed on the second branch pipe 2 instead of being directly installed on the main pipe 3. Therefore, the cleaner 22 includes a cleaner 22 that can affect the second type of raw water and thus act on the filter element 31, such as an ejector.

[0068] In one embodiment, the water tap 4 refers to a tap that provides clean water to users. The water tap 4 has a switch function. When the water tap 4 is turned on, water is discharged. When the water tap 4 is closed, water cannot be discharged.

[0069] In actual use, the water used to clean the filter element 31 can be discharged from the clean water pipeline using the water intake tap 4.

[0070] In this embodiment, the second branch pipe 2 is provided with a cleaner 22, so that when the second branch pipe 2 is used or the cleaner 22 is turned on, the filter element 31 can be cleaned by the cleaner 22, so that the service life of the filter element 31 is extended, the replacement frequency of the filter element 31 is reduced, and the user experience is improved. In addition, since the first branch pipe 1 is used to flow in type I raw water and the second branch pipe 2 is used to flow in type II raw water, the water purification pipeline can provide two types of raw water for the user, which is easier to meet the user's use needs and improves the user experience.

[0071] In a possible embodiment of the present application, a detector 5 is provided between the water inlet end of the main pipeline 3 and the water tap 4, and the detector 5 is used to detect the cleaning requirement of the filter element 31;

[0072] When the detector 5 detects that the filter element 31 needs to be cleaned, the second valve 21 is controlled to open, so that the second type of raw water enters the filter element 31 after passing through the cleaner 22 to clean the filter element 31.

[0073] In one embodiment, since the detector 5 has a detection function, the detector 5 can determine the cleaning requirement of the filter element 31 according to the detected parameters. Specifically, when the filter element 31 needs to be cleaned, the water flow in the main pipeline 3 will decrease or the water quality will deteriorate (for example, the chlorine content in the water flow increases). At this time, the water flow or water quality value detected by the detector 5 will also change accordingly, thereby determining the cleaning requirement of the filter element 31. Specifically, the cleaning requirement includes the need for cleaning and the need for cleaning.

[0074] It should be noted that when the filter element 31 is cleaned, the second valve 21 is opened, and Class II raw water will flow into the second branch pipe 2. The Class II raw water will reach the filter element 31 after passing through the cleaner 22. Under the influence of the cleaner 22, the filter element 31 is cleaned.

[0075] By adopting this implementation method, by setting up a detector 5, the detector 5 can automatically detect the cleaning need of the filter element 31 and automatically clean the filter element 31 when there is a cleaning need, thereby improving the automation level of cleaning the filter element 31, thereby reducing user operations and improving user experience.

[0076] Optionally, in an implementation of this embodiment, the detector 5 includes at least one of a flow meter 51 and a water quality probe 52 .

[0077] The flow meter 51 can detect the water flow in the main pipe 3 , and the water quality probe 52 can detect the content of one or several elements in the water flow in the main pipe 3 , such as the chlorine content.

[0078] With this implementation, the flow meter 51 can detect the water flow, so as to timely find out the blockage of the filter element 31, and the water quality probe 52 can detect the water quality, so as to timely find out the filtering condition of the water by the filter element 31. Both the flow meter 51 and the water quality probe 52 can detect the cleaning requirement of the filter element 31.

[0079] Optionally, in an implementation of this embodiment, the detector 5 includes a flow meter 51 and a water quality probe 52, the flow meter 51 is arranged between the water inlet end of the main line 3 and the water tap 4, and the water quality probe 52 is arranged between the filter element 31 and the water tap 4;

[0080] The filter element 31 includes a first water outlet and a second water outlet, and the main pipeline 3 includes a first water outlet branch 32 and a second water outlet branch 33;

[0081] The water discharged from the first water outlet flows through the water quality probe 52 and the flow meter 51 in sequence and can be discharged from at least one of the water tap 4 and the first water outlet branch 32;

[0082] The water discharged from the second water outlet is discharged from the second water outlet branch 33;

[0083] The first water outlet branch 32 is provided with a third valve 321 , and the second water outlet branch 33 is provided with a fourth valve 331 .

[0084] In one embodiment, the first water outlet and the second water outlet of the filter element 31 are on different sides of the filter element 31, for example, the first water outlet is opened on the front side of the filter element 31, and the second water outlet is opened on the bottom surface of the filter element 31. When the third valve 321 is opened and the water tap 4 is closed, the water flow entering the main line 3 passes through the filter element 31, the flow meter 51, the water quality probe 52, and the third valve 321 in sequence, and is discharged from the water outlet of the first water outlet branch 32; when the fourth valve 331 is opened and the water tap 4 is closed, the water flow entering the main line 3 passes through the filter element 31 and the fourth valve 331, and is discharged from the water outlet of the second water outlet branch 33.

[0085] With this implementation, by setting the first water outlet and the second water outlet, when different impurities in the filter element 31 need to be cleaned, water flows are discharged from different water outlets of the filter element 31, which is beneficial to improving the cleaning effect of the filter element 31. In addition, the main line 3 includes a first water outlet branch 32 and a second water outlet branch 33, and both water outlet branches are used for drainage when cleaning the filter element 31, so that the water tap 4 is not easily contaminated, improving the user experience.

[0086] Optionally, in an implementation of this embodiment, the filter element 31 includes at least one of an ultrafiltration membrane, PP cotton, activated carbon and a carbon rod;

[0087] The clean water pipeline is configured as follows:

[0088] When the ultrafiltration membrane and / or PP cotton needs to be cleaned, the cleaning water is discharged from the second water outlet branch 33; when the activated carbon and / or carbon rod needs to be cleaned, the cleaning water is discharged from the first water outlet branch 32, wherein the flow meter 51 is used to detect the cleaning needs of the ultrafiltration membrane and / or PP cotton, and the water quality probe 52 is used to detect the cleaning needs of the activated carbon and / or carbon rod.

[0089] By adopting this implementation method, when cleaning different impurities in the filter element 31, different water outlet branches are used for drainage, which is beneficial to improving the cleaning effect and cleaning efficiency of the filter element 31 and is not easy to pollute the main line 3.

[0090] Optionally, in an implementation of this embodiment, the cleaner 22 includes an ejector.

[0091] By adopting this implementation method, the ejector can increase the number of microbubbles in the water flow. When the water flows through the filter element 31, the microbubbles will release a certain amount of energy to remove the pollutants in the filter element 31 to achieve the purpose of cleaning, which is beneficial to improving the cleaning effect of the filter element 31.

[0092] Optionally, in an implementation of this embodiment, the first type of raw water is room temperature water, and the second type of raw water is hot water; or, the water inlet end of the first branch pipe is connected to the water outlet of the tap water, and the water inlet end of the second branch pipe is connected to the water outlet of the water heater.

[0093] By adopting this implementation method, both room temperature water and hot water are commonly used water. The water purification pipeline can not only provide users with room temperature purified water, but also provide users with hotter purified water, which is convenient to meet the different usage needs of users and meet the user's demand for hot water in winter, thereby improving the user experience.

[0094] The embodiment of the present application further provides a water purification pipeline control method, which is applied to the water purification pipeline described above, wherein the detector is used to detect the flow value and / or chlorine concentration on the main pipeline, and the method includes:

[0095] If the flow value collected by the detector is lower than a preset flow threshold, the first branch pipeline is controlled to be closed and the second branch pipeline is controlled to provide Class II raw water to clean the filter element;

[0096] And / or, if the chlorine concentration collected by the detector exceeds a preset concentration threshold, the first branch pipeline is controlled to be closed and the second branch pipeline is controlled to provide Class II raw water to clean the filter element.

[0097] By adopting this embodiment, automatic detection of filter element cleaning is achieved using a flow meter and a water quality probe, thereby realizing automatic cleaning, which increases the service life and filtering effect of the filter element. The filter element cleaning process does not require user control, reduces the frequency of user filter element replacement, and improves the user experience.

[0098] Optionally, in an implementation of this embodiment, it is applied to the above-mentioned water purification pipeline, such as Figure 2 As shown, the method includes:

[0099] S100. If the flow value collected by the flow meter is lower than the preset flow threshold, the second valve and the fourth valve are controlled to be opened and the water outlet tap is controlled to be closed, so that the second type of raw water passes through the cleaner and is discharged from the second water outlet branch through the second water outlet of the filter element to clean the filter element.

[0100] S102. If the chlorine concentration collected by the water quality probe exceeds a preset concentration threshold, the second valve and the third valve are controlled to be opened and the water outlet tap is controlled to be closed, so that the second type of raw water passes through the cleaner and is discharged from the first water outlet of the filter element from the first water outlet branch to clean the filter element.

[0101] By adopting this embodiment, automatic detection of filter element cleaning is achieved using a flow meter and a water quality probe, thereby realizing automatic cleaning, which increases the service life and filtering effect of the filter element. The filter element cleaning process does not require user control, reduces the frequency of user filter element replacement, and improves the user experience.

[0102] Optionally, in an implementation of this embodiment, the method further includes:

[0103] When the second valve and the fourth valve are opened for a first preset time, the filter element is soaked with Class II raw water, and after soaking, the filter element is rinsed with Class I raw water and the water is discharged from the second water outlet branch;

[0104] When the second valve and the third valve are opened for a preset second time period, the filter element is soaked in Class II raw water and then rinsed with Class I raw water and drained from the first water outlet branch.

[0105] When the present implementation method is used to clean the filter element, not only Class II raw water is used for cleaning, but also Class I raw water is used for soaking and final rinsing, which improves the cleaning effect of the filter element and helps to improve the cleanliness of the water purification pipeline.

[0106] Optionally, in an implementation of this embodiment, soaking the filter element with the second type of raw water and then flushing the filter element with the first type of raw water and draining the water through the second water outlet branch includes:

[0107] Close the second valve and the fourth valve and, after a preset third time period, open the first valve and the fourth valve;

[0108] The method of soaking the filter element with the second type of raw water and then flushing the filter element with the first type of raw water and draining the water through the first water outlet branch includes:

[0109] The second valve and the third valve are closed and opened after a preset fourth time period.

[0110] By adopting this implementation method, the filter element can be immersed and flushed by controlling the opening and closing states of different valves. The control process is simple, and it is easy to improve the cleaning effect of the filter element and reduce the cleaning cost.

[0111] Optionally, in an implementation of this embodiment, the method further includes:

[0112] When the filter element needs to be cleaned, the cleaning time is the preset target time period of the next day.

[0113] By adopting this implementation method, by setting a preset target time period, the cleaning process of the filter element is not likely to affect the user's normal use of purified water, thereby improving the user's experience.

[0114] In the above-mentioned embodiments of the present application, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, please refer to the relevant description of other embodiments. The steps shown in the relevant flow chart can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flow chart, in some cases, the steps shown or described can be executed in an order different from that here. In other words, the order of steps described in the foregoing embodiments is only an example, and it is also within the scope of protection of the embodiments of the present application to reasonably adjust the order of steps based on the content of the embodiments of the present application.

[0115] In a specific implementation of the embodiment of the present application, the water purification pipeline and the control method thereof include the following processing procedures:

[0116] There are two types of purification equipment on the market, namely general water treatment equipment and reverse osmosis treatment equipment. The former can purify some pollutants in the water, and its core components are ultrafiltration membrane, pp cotton, and activated carbon. The filtered water is clean water; the latter can purify most pollutants in the water, and its core components are reverse osmosis membrane, and the filtered water is pure water. At present, dual-outlet water purifiers that contain both clean water and pure water are the mainstream sales in the market. Clean water is used to wash vegetables and rice, and pure water is used for direct drinking.

[0117] Since drinking water requires hot water, adding a heating module to the tap can solve this problem. The purified water at the vegetable washing end is not affected in the summer, but in the winter, the weather is cold and the temperature of the pre-treated tap water is also low, which is not a good experience for washing vegetables. At present, this problem can be solved by adding a heating module at the water purification end, but there are certain problems. First, the cost is high, and second, the scale in the tap water will accumulate in the heating module and eventually affect the heat transfer. The heating module cannot be used on a large scale.

[0118] In addition, pretreatment is generally a composite filter element, which often contains ultrafiltration membrane or PP cotton to intercept particulate matter, rust, and sediment in the water, as well as activated carbon / carbon rods to absorb organic matter and residual chlorine in the water. During pretreatment, due to blockage of ultrafiltration or PP cotton, the flow rate is small and the service life expires. The design of the carbon rod is based on the removal rate of residual chlorine. When the service life expires, it will remind you to change the core, which will cause the problem of frequent core replacement.

[0119] like Figure 3 The figure is a schematic diagram of the structure of a water purification pipeline in a specific implementation, wherein the roles and functions of each component are as follows:

[0120] Solenoid valve 1: used to open normal temperature water;

[0121] Solenoid valve 2: used to open hot water;

[0122] Ejector: It consists of a nozzle and a diffuser. Its working principle is based on Bernoulli's principle, that is, when the fluid is accelerated through a narrow nozzle and released, the number of microbubbles dissolved in the water will increase. When the microbubbles of warm water pass through ultrafiltration or PP, they will release a certain amount of energy, stripping the pollutants in the filter element to achieve the purpose of cleaning. At the same time, if hot water is used, the hot water pre-treated by the ejector can also clean fruits and vegetables.

[0123] Pretreatment filter element: a filter element used to purify raw water, which can be a combination of ultrafiltration membrane, PP cotton and activated carbon / carbon rod;

[0124] Water quality probe: mainly detects the residual chlorine content in the water, used to detect the life of activated carbon and whether thermal regeneration treatment is required;

[0125] Flow meter: used to calculate the flow of the pre-treatment filter element. When the filter element flow is lower than the set value, the thermal regeneration control logic is executed. It can be placed before or after the pre-treatment filter element. It can also be called a pulse counter, etc.

[0126] Water tap: responsible for opening normal temperature water and hot water;

[0127] Solenoid valve 3: used to open the activated carbon regeneration wastewater water channel after thermal regeneration.

[0128] Solenoid valve 4: used to open the ultrafiltration membrane or PP water channel wastewater channel after thermal regeneration.

[0129] The control method of the water purification pipeline includes the following processes:

[0130] Tap water collection stage

[0131] ① When the faucet is turned to the normal temperature water position, solenoid valve 1 is opened, solenoid valve 2, solenoid valve 3 and solenoid valve 4 are closed, and normal temperature water enters the pre-treatment filter element through solenoid valve 1, passes through the pre-treatment filter element, and then flows out of the faucet after passing through the flow meter;

[0132] ② When the faucet is turned to the hot water position, solenoid valve 2 opens, solenoid valve 1, solenoid valve 3 and solenoid valve 4 are closed, and the hot water enters the pre-treatment filter element through solenoid valve 2, and then flows out of the faucet after passing through the flow meter after the pre-treatment filter element; the hot water is tap water heated by the water heater, which is used for daily water such as bathing and washing face. The water temperature is generally set to 45-55℃, and the water temperature experience is best at this time.

[0133] Ultrafiltration membrane or PP cotton regeneration control logic

[0134] When the flow meter detects a flow rate lower than the set value, for example, ≤4L / min, the system will perform the ultrafiltration membrane or PP cotton regeneration control logic. The specific logic is as follows:

[0135] ① Solenoid valve 1 and solenoid valve 3 are closed, solenoid valve 2 and solenoid valve 4 are opened at the same time, the water tap is closed, and hot water passes through the ejector to form hot water with microbubbles, which flushes the surface pollutants of the ultrafiltration membrane or PP cotton. After the operation reaches the set time (10-60s), solenoid valve 2 and solenoid valve 4 are closed at the same time, and the hot water completely soaks the pre-treatment filter element;

[0136] ② When the soaking reaches the set time (1-60min), solenoid valve 1 and solenoid valve 4 are opened, solenoid valve 2 and solenoid valve 3 are closed, and the water tap is closed. After the operation reaches the set time (10-60s), solenoid valves 1 and 4 are closed at the same time. At this time, the normal temperature water will flush away the pollutants precipitated by the microbubble hot water regeneration, and the regeneration is completed.

[0137] ③ The control logic does not execute the regeneration logic on the day, and the regeneration logic is T+1, which is set to be completed between 2 am and 4 am the next day;

[0138] ④When the flow meter detects a flow rate lower than the set value, for example, ≤4L / min, repeat steps ① and ②.

[0139] Activated carbon regeneration control logic

[0140] When the water quality probe detects a residual chlorine concentration higher than the set value, for example ≥0.05mg / L, the system will perform activated carbon regeneration control logic. The specific logic is as follows:

[0141] ① Solenoid valve 1 and solenoid valve 4 are closed, solenoid valve 2 and solenoid valve 3 are opened at the same time, the water tap is closed, and hot water passes through the ejector to form hot water with microbubbles to flush the activated carbon. After the operation reaches the set time (10-60s), solenoid valve 2 and solenoid valve 3 are closed at the same time, and the hot water completely soaks the pre-treatment filter element;

[0142] ② When the soaking reaches the set time (1-60min), solenoid valve 1 and solenoid valve 3 are opened, solenoid valve 2 and solenoid valve 4 are closed, and the water tap is closed. The microbubble hot water breaks the adsorption balance between it and the adsorbate, so that the adsorbate is parsed and desorbed. After the operation reaches the set time (10-60s), solenoid valves 1 and 3 are closed at the same time. At this time, the normal temperature water will flush away the organic and other pollutants regenerated and parsed by the microbubble hot water, and the regeneration is completed.

[0143] ③ The control logic does not execute the regeneration logic on the day, and the regeneration logic is T+1, which is set to be completed between 2 am and 4 am the next day;

[0144] ④When the water quality probe detects a residual chlorine concentration higher than the set value, for example ≥0.05mg / L, repeat steps ① and ②.
