Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water purification, in particular to a TDS regulating water purification system and equipment. Background Art
[0002] Total dissolved solids (TDS), also known as total dissolved solids, is measured in milligrams per liter (mg / L) and indicates the number of milligrams of dissolved solids in 1 liter of water. The higher the TDS value, the more dissolved solids the water contains. Total dissolved solids refers to the total amount of all solutes in the water, including both inorganic and organic matter. Conductivity can generally be used to provide a rough estimate of the salt content in a solution. Generally, higher conductivity indicates higher salt content and higher TDS. Inorganic substances, in addition to dissolved ions, may also contain molecular inorganic substances. Since the organic matter and molecular inorganic substances contained in natural water are generally not considered, the salt content is generally referred to as total dissolved solids.
[0003] Different applications, such as brewing tea or coffee, require different water quality. For example, water with a TDS of around 150% fully dissolves caffeine and other ingredients, resulting in a superior coffee taste. Therefore, water with varying TDS levels is required for different applications.
[0004] Nowadays, coffee shops and milk tea shops generally require adjustable water TDS to meet consumers' diverse taste preferences. Existing solutions for adjustable TDS in coffee and milk tea shop water purification equipment typically rely on manual valves to control the flow of purified and pure water to achieve different TDS values. This approach has the following drawbacks: TDS values vary between regions, requiring manual adjustment of the TDS value at the water purification equipment outlet, which also requires manual correction after a period of use. This lack of intelligence requires improvement. Utility Model Content

[0024] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions of this application will be described in detail below through implementation methods with reference to the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. In the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0025] like Figure 1 As shown, the first embodiment of the present application provides a TDS regulating water purification system that can automatically adjust the TDS value.
[0026] The system includes a clean water pipeline 1, a pure water pipeline 2 and a mineralized water pipeline 3.
[0027] The clean water pipeline 1 is provided with a clean water preparation device 11 and a clean water preparation control component 12;
[0028] The pure water pipeline 2 is connected to the outlet end of the pure water preparation device 11, and the pure water pipeline 2 is provided with a pure water preparation component 21 and a pure water preparation control component 22;
[0029] The mineralized water pipeline 3 is connected to the outlet end of the pure water preparation component 21, and the mineralized water preparation device 31 and the mineralized water preparation control component 32 are provided on the mineralized water pipeline 3;
[0030] The purified water pipeline 1 , the pure water pipeline 2 and the mineralized water pipeline 3 merge at the end to form a merged pipeline 4 .
[0031] During operation, the clean water pipeline 1 is used to prepare the raw water input into the clean water pipeline 1 into clean water, the pure water pipeline 2 further processes the clean water prepared by the clean water pipeline 1 to prepare it into pure water, and the mineralized water pipeline 3 further processes the pure water prepared by the pure water pipeline 2 to prepare it into pure water. In terms of TDS value, the pure water prepared by the pure water pipeline 2 has a lower TDS value, the clean water prepared by the clean water pipeline 1 has a medium TDS value, and the mineralized water prepared by the mineralized water pipeline 3 has the highest TDS value. Therefore, the clean water pipeline 1, the pure water pipeline 2 and the mineralized water pipeline 3 are merged at the end to form a confluent pipeline, and the pure water, clean water and mineralized water are mixed in different proportions, so that the preparation of clean water with any TDS value within the range from the TDS value of pure water to the TDS value of mineral water can be achieved.
[0032] Since the TDS regulating water purification system in the first embodiment can prepare purified water with any TDS value within the range from the TDS value of pure water to the TDS value of mineralized water, when the pipelines are merged, the above purpose can be achieved by merging the pure water pipeline and the mineralized water pipeline, and the control mode can also be simplified. Based on the above working principle, a second embodiment is further proposed on the basis of the first embodiment, as shown in FIG. Figure 2 As shown, the TDS regulating water purification system of the second embodiment includes a purified water pipeline 1, a pure water pipeline 2 and a mineralized water pipeline 3.
[0033] The clean water pipeline 1 is provided with a clean water preparation device 11 and a clean water preparation control component 12;
[0034] The pure water pipeline 2 is connected to the outlet end of the pure water preparation device 11, and the pure water pipeline 2 is provided with a pure water preparation component 21 and a pure water preparation control component 22;
[0035] The mineralized water pipeline 3 is connected to the outlet end of the pure water preparation component 21, and the mineralized water preparation device 31 and the mineralized water preparation control component 32 are provided on the mineralized water pipeline 3;
[0036] The purified water pipeline 1 , the pure water pipeline 2 and the mineralized water pipeline 3 merge at the end to form a merged pipeline 4 .
[0037] The pure water pipeline 2 and the mineralized water pipeline 3 merge at the end to form a confluence pipeline 5 , which then merges with the end of the purified water pipeline 1 to connect to the confluence pipeline 4 .
[0038] The functions of the various components and the overall working principle of the second embodiment are the same as those of the first embodiment, and will not be described again here.
[0039] In the above-mentioned first and second embodiments, based on the different requirements for clean water preparation, the clean water preparation device 11, the pure water preparation device 21, the mineralized water preparation device 31 and the clean water preparation control component 12, the pure water preparation control component 22, and the mineralized water preparation control component 32 can all adopt different component selections and component combinations. In order to provide a detailed embodiment to combine the working mode of the expression system, a third embodiment is further proposed on the basis of the second embodiment in combination with the specific component connection structure.
[0040] like Figure 3 As shown, in the third embodiment, in the clean water pipeline 1, the clean water preparation device 11 is a pre-filter element, and the clean water preparation control component 12 includes a clean water TDS probe 121, a clean water control valve 122, a clean water flow meter 123 and a clean water one-way valve 124 arranged on the clean water pipeline.
[0041] The pre-filter is used to filter raw water to obtain purified water. The outlet of the pre-filter is divided into two branches. One branch is used as the purified water pipeline itself to install the purified water TDS probe 121, purified water control valve 122, purified water flowmeter 123, and purified water check valve 124 included in the purified water preparation control assembly 12. The other branch is used to connect to the pure water pipeline 2 to supply purified water to the pure water pipeline 2. In the purified water preparation control assembly 12, the purified water TDS probe 121 is used to detect the TDS value of the purified water, the purified water control valve 122 controls the output of the purified water by switching, the purified water flowmeter 123 is used to obtain the flow rate of the purified water, and the purified water check valve 124 can prevent the purified water from flowing back in the pipeline.
[0042] In the pure water pipeline 2, the pure water preparation component 21 includes a solenoid valve 211, a booster pump 212 and a pure water preparation device 213 arranged on the pure water pipeline. In this embodiment, the pure water preparation device 213 adopts an RO membrane filter. The working principle of the RO membrane filter is based on the process of osmosis and reverse osmosis. The RO semi-permeable membrane is used to separate and purify water, and can filter out impurities, ions, microorganisms and other substances in the water, thereby obtaining high-purity water; the solenoid valve 211 is used to cooperate with the RO membrane filter to control the water supply entering the RO membrane filter to ensure that a stable water flow is provided when needed; the booster 212 pump generates high-pressure water flow through mechanical movement. The high-pressure water flow can drive the water flow entering the RO membrane filter to maintain a certain pressure, so that it passes through the RO membrane filter under the action of pressure. The micropores on the surface of the RO membrane are small, and the booster pump is required to provide a higher pressure to overcome this resistance so that water molecules can pass through the RO membrane filter smoothly.
[0043] According to the working mode of the RO membrane filter, a wastewater pipe is also connected to the RO membrane filter, and a wastewater valve is provided on the wastewater pipe. The connection and working principle of the wastewater pipe and the wastewater valve on the RO membrane filter can refer to the relevant settings on the existing pure water preparation equipment, which will not be repeated here. Figure 3 An example is given in .
[0044] The outlet end of the pure water preparation device 213 also has two branches, one branch serves as the pure water pipeline itself to install the pure water preparation control component 22, and the other branch is used to connect to the mineralized water pipeline 3 to supply pure water to the mineralized water pipeline 3.
[0045] The pure water preparation control assembly 22 includes a pure water TDS probe 221, a pure water control valve 222, a pure water flowmeter 223, and a pure water check valve 224, all of which are located on the pure water pipeline. The pure water TDS probe 221 is used to detect the TDS value of the pure water, the pure water control valve 222 controls the output of the pure water by switching, the pure water flowmeter 223 is used to obtain the flow rate of the pure water, and the pure water check valve 224 prevents the pure water from flowing back into the pipeline.
[0046] In the mineralized water pipeline 3, the mineralized water preparation device 31 is a mineralized filter element, which releases minerals such as calcium (Ca), magnesium (Mg), zinc (Zn), iron (Fe), selenium (Se) and other mineral elements through the filter element material, which are used to increase and adjust the TDS value of pure water. The mineralized water preparation control component 32 includes a mineralized water TDS probe 321, a mineralized water control valve 322, a mineralized water flowmeter 323 and a mineralized water check valve 324.
[0047] Among them, the mineralized water TDS probe 321 is used to detect the TDS value of mineralized water, the mineralized water control valve 322 controls the output of purified water through switching, the mineralized water flow meter 323 is used to obtain the mineralized flow, and the mineralized water check valve 324 is used to prevent the mineralized water from flowing back in the pipeline.
[0048] In this embodiment, based on the pipeline setting of the second embodiment, in order to obtain the TDS value of the mixed water in the confluence pipeline 5 for feedback of the TDS adjustment result or as a comparison parameter with the set value, a confluence TDS probe 6 is provided on the confluence pipeline.
[0049] A fourth embodiment of the present application provides a TDS regulating water purification device, which includes any one of the TDS regulating water purification systems of the first to third embodiments.
[0050] Based on the composition structures of the TDS-regulated water purification systems and devices in the first to fourth embodiments, the following control can be implemented in terms of TDS-regulated water purification.
[0051] When using the system, it can include pure water intake mode, purified water intake mode and adjustable TDS intake mode. Users can set the corresponding water intake mode according to their needs.
[0052] Among them, the adjustable TDS water intake mode includes normal mode and mineralization mode.
[0053] When the user selects the pure water intake mode, the solenoid valve 211 and the pure water control valve 222 are opened respectively, and the raw water passes through the water purification device 11, the solenoid valve 211 and the pure water preparation device 21, and becomes pure water after passing through the pure water preparation device 21. Then, after passing through the pure water TDS probe 221, the pure water control valve 222, the pure water flow meter 223 and the pure water one-way valve 224, the raw water finally passes through the confluence TDS probe 6 and flows to the water outlet.
[0054] When the user selects the purified water intake mode, the purified water control valve 122 is opened, and the raw water is converted into purified water through the purified water preparation device 11, and then passes through the purified water TDS probe 121, the purified water control valve 122, the purified water flow meter 123 and the purified water one-way valve 124 and flows to the water outlet.
[0055] When the user selects the adjustable TDS water mode, sets the desired mineralization concentration and water mode, the system will read the corresponding data, such as the desired mineralization concentration, and record the set mineralization concentration as TDS5. Here, the water mode includes normal mode and mineralization mode.
[0056] Normal mode: The pure water TDS probe 221 and the purified water TDS probe 121 detect the TDS values in the current pure water pipeline and the purified water pipeline respectively, and record them as TDS1 and TDS3 respectively.
[0057] When TDS5<TDS1, it indicates that the current set concentration is too low.
[0058] When TDS5 = TDS1, the solenoid valve 211 and the pure water control valve 222 are opened, and the purified water control valve 122 and the mineralized water control valve 322 are closed.
[0059] When TDS5>TDS3, it automatically switches to mineralization mode.
[0060] When TDS1<TDS5≤TDS3, the solenoid valve 211, the pure water control valve 222 and the clean water control valve 122 are opened at the same time, and the mineralized water control valve 322 is closed. The amount of water passing through the pure water flow meter 223 is set to V1, and the amount of water passing through the clean water flow meter 123 is set to V2. According to the law of conservation of mass: TDS1*V1+TDS3*V2=k*TDS5*(V1+V2), the deformation results in V1 / V2=(TDS3-k*TDS5) / (k*TDS5-TDS1). 3 are recorded as L1 and L2 respectively, so when the pure water control valve 222 and the clean water control valve 122 are opened for the same time, theoretically L1 / L2=(TDS3-k*TDS5) / (k*TDS5-TDS1), at this time, the actual flow L1 tested by the pure water flowmeter 223 is used to adjust the opening of the clean water control valve 122 in real time, so that the actual flow rate of purified water L2=L1*(k*TDS5-TDS1) / (TDS3-k*TDS5), the pure water pipeline and the clean water pipeline are directly mixed in the water channel, the preset TDS5 value can be reached and continuous water supply can be achieved.
[0061] Wherein, k is a correction coefficient, which is corrected by comparing the TDS value of the confluence TDS probe 6 with the set value TDS5.
[0062] Mineralization mode: the pure water TDS probe 221 and the mineralized water TDS probe 321 detect the TDS values in the current pure water pipeline and the mineralized water pipeline respectively, which are recorded as TDS1 and TDS4 respectively.
[0063] When TDS4 is less than TDS1, it indicates that the mineralization concentration of the filter element is too low and the mineralization material needs to be replaced in time (the mineralization filter element 12 is mainly added with natural minerals, including potassium, sodium, calcium, magnesium, strontium, metasilicic acid and other mineral elements).
[0064] When TDS5<TDS1, it indicates that the current set concentration is too low.
[0065] When TDS5 ≤ TDS4, the solenoid valve 211, pure water control valve 222, and mineralized water control valve 322 are simultaneously opened, the clean water control valve 122 is closed, and the amount of water passing through the pure water flowmeter 223 is set to V1, and the amount of water passing through the mineralized water flowmeter 323 is set to V3. According to the law of conservation of mass: TDS1*V1+TDS4*V3=k*TDS5*(V1+V3), the transformation yields V1 / V3=(TDS4-k*TDS5) / (k*TDS5-TDS1). The flow rates of the pure water flowmeter 223 and the mineralized water flowmeter 323 are respectively recorded as L1 and L3. Therefore, when the pure water control valve 222 and the mineralized water control valve 322 are opened for the same time, theoretically, when L1 / L3=(TDS4-k*TDS5) / (k*TDS5-TDS1), the target concentration can be met. At this time, the pure water control valve 222 and the mineralized water control valve 322 are opened at the same time, and the pure water and mineralized water flow rates measured by the pure water flowmeter 223 and the mineralized water flowmeter 323 are L(1) and L(3) respectively. At this time, the system flow rate L4=L(1)+L(3), and then the pure water control valve 222 and the mineralized water control valve 322 are adjusted respectively to make the flow rates of the pure water pipeline 2 and the mineralized water pipeline 3 respectively: L1=L4-L4 / [(TDS4-k*TDS5) / (k*TDS5-TDS1)+1], L3=L4 / [(TDS4-k*TDS5) / (k*TDS5-TDS1)+1]. The pure water pipeline 2 and the mineralized water pipeline 3 are directly mixed in the water channel, and the TDS (total dissolved solids) are mainly minerals such as potassium, sodium, calcium, magnesium, strontium, and metasilicic acid, which can realize continuous mineralized water supply. Where k is the correction factor. The system will automatically make corrections based on the TDS value of the confluence TDS probe 6 compared with the set value TDS5. When TDS5>TDS4, it indicates that the set concentration is too high and recommends lowering the set concentration.
[0066] That is, in the TDS water purification system, by installing corresponding pure water TDS probes 221, purified water TDS probes 121, and mineralized water TDS probes 321 in the pure water pipeline, purified water pipeline, and mineralized water pipeline, the pure water TDS probes 221, purified water TDS probes 121, and mineralized water TDS probes 321 can respectively detect the TDS values of the current pure water pipeline, purified water pipeline, and mineralized water pipeline. The confluence TDS probe 6 can detect the TDS value of the water after the pure water pipeline and the mineralized water pipeline are mixed.
[0067] Pure water, clean water, and mineralized water are obtained through the pure water pipeline, the clean water pipeline, and the mineralized water pipeline, respectively. The pure water control valve 222 and the pure water flowmeter 223 in the pure water pipeline, the clean water control valve 122 and the clean water flowmeter 123 in the clean water pipeline, and the mineralized water control valve 322 and the mineralized water flowmeter 323 in the mineralized water pipeline can be used to automatically control and adjust the pure water flow rate of the pure water pipeline, the clean water flow rate of the clean water pipeline, and the flow rate of the mineralized water pipeline, respectively. Therefore, by detecting the TDS values of the pure water pipeline, the clean water pipeline, and the mineralized water pipeline in real time and controlling the on / off state and flow rate of the pure water pipeline, the clean water pipeline, and the mineralized water pipeline, the TDS value of the outlet water can be automatically adjusted, solving the problem of existing water purification equipment that controls the flow rate of purified water and pure water through manual valves and requires manual adjustment to correct the TDS value of the water at the outlet.
[0068] In addition, for existing water purification equipment, if the local water quality TDS is low, the target TDS value will still not be achieved by combining purified water with pure water. For example, if the local water quality TDS is 90ppm and the coffee shop requires 130ppm, no matter how it is adjusted, it will not meet the 130ppm requirement. Since the water purification system described in this application is equipped with a mineralized water pipeline to produce mineralized water, even if the local water quality TDS is low, by mixing mineralized water and pure water, water bodies with different TDS values can be obtained at the water outlet, which solves the problem of existing water purification equipment being unable to achieve the target TDS value.
[0069] In summary, the TDS regulating water purification system and equipment described in the embodiments of the present application can achieve the following beneficial effects:
[0070] 1. Intelligent Control. The solenoid valve 211 and the pure water control valve 222 automatically adjust the flow rate of the pure water pipeline, the clean water control valve 122 automatically adjusts the flow rate of the clean water pipeline, and the solenoid valve 211 and the mineralized water control valve 322 automatically adjust the flow rate of the mineralized water pipeline. Furthermore, the TDS values of the pure water pipeline, the clean water pipeline, and the mineralized water pipeline are detected. The set mineralization concentration TDS5 is compared with the TDS2 value detected by the confluence TDS probe 6 for automatic correction, thereby achieving the purpose of automatically adjusting the TDS value at the water outlet.
[0071] 2. Precise control. By real-time monitoring of the TDS values of pure water pipelines, purified water pipelines, and mineralized water pipelines, different TDS values can be freely selected in real time according to different water needs, with precise control. The system compares the set mineral concentration TDS5 with the TDS2 value detected by the confluence TDS probe 6, automatically correcting the coefficient to ensure system accuracy.
[0072] 3. Healthy drinking water. A mineralization mode can be selected to mix the pure water produced by the pure water pipeline with the mineralized water produced by the mineralized water pipeline in proportion, adding mineral elements to the pure water to meet the taste / health needs in different scenarios.
[0073] 4. Stepless adjustment. Each water production can be accurately detected and calculated by the system, and the flow rate is automatically adjusted for mixing. It is not affected by the water collection interval and the water quality in different regions, and the required TDS value can be achieved by stepless adjustment.
[0074] The above description is only a preferred embodiment of the embodiment of the present application, and does not limit the patent scope of the embodiment of the present application. Any equivalent structure or equivalent process transformation made using the embodiment description and drawings of the present application, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the embodiment of the present application.
