Abstract
Description
Technical Field
[0001] This invention specifically relates to a water purifier system for brewing tea. Background Technology
[0002] With the increasing awareness of healthy drinking water, household water purification equipment has been widely used in daily life, especially in scenarios where water quality requirements are high, such as tea brewing and direct drinking. Multi-stage composite filter water purifiers have become the mainstream choice. Existing water purifiers typically use a fixed series filter structure, where water passes through multiple filtration units in sequence, including pre-filters (such as PP cotton and activated carbon), core filter membranes (such as RO reverse osmosis membranes or nanofiltration membranes), and post-activated carbon, to achieve comprehensive removal of pollutants such as residual chlorine, heavy metals, bacteria, scale, and odors.
[0003] However, this traditional design has a significant drawback: all filters are forced to activate every time water is used, regardless of whether the actual water demand requires such deep purification. For example, when only washing teaware or brewing beverages that don't require high-purity water, the user doesn't need the high-purity water treated by all filters, but the system still forces water to flow through all the filter media. This causes pre-filters (such as carbon fiber and PP cotton) to become prematurely saturated due to frequent use, and post-filters (such as granular activated carbon) to age faster due to unnecessary water flow. More seriously, because each filter has a different lifespan, but most products use a "complete set simultaneous replacement" strategy, once any filter reaches its lifespan threshold, the user is often forced to replace the entire set of filters, resulting in a large amount of filter media that hasn't yet exhausted its function being prematurely discarded.
[0004] This maintenance model not only significantly increases user costs but also leads to serious resource waste and environmental pollution, contradicting the current advocacy of green, low-carbon, and sustainable development. Although some high-end products have introduced filter life monitoring functions, they are still based on total water consumption estimates and cannot distinguish the actual load of different filters under different water usage scenarios, making it difficult to achieve precise management.
[0005] This invention was developed precisely because of the aforementioned shortcomings. Summary of the Invention
[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a more applicable and environmentally friendly water purifier system for brewing tea.
[0007] This invention is achieved through the following technical solution:
[0008] This invention provides a water purifier system for brewing tea, including a water purifier and an automatic kettle. The automatic kettle has a water inlet channel for filling the kettle with water. The water purifier has a water inlet interface for inputting water. The outlet end of the water inlet interface is connected to the water inlet channel. The end of the water inlet channel is connected to a first filter element group. The outlet end of the first filter element group is connected to a first branch channel and a transition channel. The outlet end of the transition channel is connected to a second filter element group. The outlet end of the second filter element group is connected to a second branch channel and a third branch channel. A third filter element group is arranged on the third branch channel. The water purifier also has a control component for controlling the on / off state of the three branch channels. The outlet ends of the three branch channels are all connected to the water inlet channel of the automatic kettle. The automatic kettle also has an operation panel for user operation to input information and a first control module connected to the operation panel. The water purifier has a second control module that is signal-connected to the first control module. The second control module is electrically connected to the control component to control the on / off state of the three branch channels according to the information input by the user.
[0009] As described above, in the water purifier system for tea brewing, the control component includes a first solenoid valve, a second solenoid valve, and a third solenoid valve that are signal-connected to the second control module. The first solenoid valve is arranged on the first branch channel, the second solenoid valve is arranged on the second branch channel, and the third solenoid valve is arranged on the third branch channel. Alternatively, the control component is a three-position four-way solenoid valve, with the outlets of the three branch channels respectively connected to the three inlets of the three-position four-way solenoid valve, and the outlet of the three-position four-way solenoid valve connected to the water injection channel.
[0010] The water purifier system for tea brewing described above also includes a first flow meter, a second flow meter, and a third flow meter. The first flow meter is arranged on the first branch channel, the second flow meter is arranged on the second branch channel, and the third flow meter is arranged on the third branch channel. All three flow meters are connected to the second control module to collect flow data from the three branch channels.
[0011] The water purifier system for tea brewing described above also includes a booster pump, which is arranged in the water inlet channel or the transition channel.
[0012] In the tea-brewing water purifier system described above, the first filter assembly includes at least one carbon fiber filter element.
[0013] In the tea-brewing water purifier system described above, the second filter cartridge assembly includes at least one nanofiltration membrane filter cartridge.
[0014] In the tea-brewing water purifier system described above, the third filter assembly includes at least one granular activated carbon filter.
[0015] As described above, the water purifier system for tea brewing integrates a user input unit on the control panel for user operation and information input. The user input unit includes at least one of a touch screen and physical buttons. The user input unit has at least three function selections: cleaning function, boiling water function, and tea brewing function. When the user inputs the function selection signal for cleaning function, the second control module controls the first channel to open and the other two channels to close. When the user inputs the function selection signal for boiling water function, the second control module controls the second channel to open and the other two channels to close. When the user inputs the function selection signal for tea brewing function, the second control module controls the third channel to open and the other two channels to close.
[0016] As described above, the water purifier system for brewing tea has a display screen unit on top that is connected to the second control module.
[0017] Compared with existing technologies, this invention has the following advantages: This technical solution sets up three independently controllable filtration branches, corresponding to three water usage scenarios: washing, boiling water, and brewing tea. This allows for the activation of different numbers and types of filter cartridges as needed, avoiding the excessive consumption of filter cartridges caused by traditional water purifiers that force full-stage filtration regardless of water demand. Combined with the solenoid valve control component and the user control panel, the system can automatically switch water supply paths according to user selection, ensuring that each level of filter cartridge, such as carbon fiber, nanofiltration membrane, and granular activated carbon, only operates when necessary, significantly reducing ineffective water flow. Simultaneously, combined with the flow meters of each branch, the actual water consumption is accurately measured, allowing for independent assessment of the actual usage load and remaining lifespan of each filter cartridge. Real-time feedback is provided through the display screen, supporting replacement on demand rather than complete system scrapping. This significantly reduces consumable waste, lowers operating costs, and extends the overall system lifespan. While ensuring water quality adaptability, it effectively practices the design concepts of resource conservation and green sustainability. Attached Figure Description

[0022] The invention will be further described below with reference to the accompanying drawings:
[0023] The orientations described in this invention specification, such as "up," "down," "left," "right," "front," and "back," are based on the orientations in the accompanying drawings and are intended to facilitate the description of the relationships between the various components. They do not indicate the unique or absolute positional relationships between the various components, but are merely one embodiment of the invention and are not a limitation on its implementation.
[0024] like Figures 1 to 4 As shown, this embodiment introduces a water purifier system for brewing tea, including a water purifier 1 and an automatic kettle 2. The automatic kettle 2 is equipped with a water inlet channel 20 for filling the kettle with water. The automatic kettle 2 can be fitted with a kettle, a heating device for boiling water, a water pump, etc., and can be referenced to the patent solution with patent number CN202122717039.3 entitled "An Electric Kettle with Automatic Water Filling". The water purifier 1 has a water outlet 100, which is connected to the water inlet channel 20 of the automatic kettle 2 via a flexible hose or rigid pipe to deliver water.
[0025] The water purifier 1 is provided with a water inlet interface 11 for inputting water source, which is used to directly connect to a tap water faucet or to connect to a tap water pipeline through a hose. The water outlet end of the water inlet interface 11 is connected to a water inlet channel 12. The end of the water inlet channel 12 is connected to a first filter element group 13. The water outlet end of the first filter element group 13 is connected to a first branch channel 101 and a transition channel 121. The water outlet end of the transition channel 121 is connected to a second filter element group 14. The water outlet end of the second filter element group 14 is connected to a second branch channel 102 and a third branch channel 103. A third filter element group 15 is arranged on the third branch channel 103.
[0026] This multi-stage diversion flow path design enables intelligent switching of water sources between different filtration paths, allowing the system to dynamically adjust the depth of water treatment according to the usage scenario, avoiding over-filtration or under-filtration.
[0027] The water purifier 1 is also equipped with a control component for controlling the on / off state of the three branch channels. The water outlets of the three branch channels are all connected to the water inlet channel 20 of the automatic kettle 2. The water outlets of the three branch channels can be connected to the water inlet channel 20 through the four-way pipe connector 19, or they can be connected to different positions of the water inlet channel 20, as long as the water source can be connected and transported.
[0028] The automatic kettle 2 is also equipped with an operation panel 21 for user input and a first control module 22 connected to the operation panel 21. The operation panel 21 integrates a user input unit, which can be a touchscreen or physical buttons, as long as it allows user input. This user input unit primarily allows users to select different operating modes, such as cleaning, boiling water, and tea brewing, using three function buttons. By precisely matching user needs with the filtration path, the system significantly improves energy and consumable utilization efficiency while meeting different water usage scenarios.
[0029] The water purifier 1 is equipped with a second control module 16 that is signal-connected to the first control module 22. The two control modules are connected by a wire, which can be arranged along the flexible hose between them. Alternatively, they can transmit signals wirelessly via Wi-Fi, Bluetooth, or other wireless methods. The second control module 16 is electrically connected to the control component to control the on / off state of the three branch channels based on user input.
[0030] With the above structure, the water purifier 1 can operate in at least three modes: when the first channel 101 supplies water, the water source passes through only the first filter element group 13; when the second channel 102 supplies water, the water source passes through the first filter element group 13 and the second filter element group 14; and when the third channel 103 supplies water, the water source passes through all three filter element groups in sequence. These three operating modes of the water purifier 1 correspond to the three operating modes of the automatic kettle 2. When the user inputs the corresponding function information through the operation panel 21, the first control module 22 sends a signal to the second control module 16, thereby enabling different operating modes based on the user's selection. For example, the cleaning function is used to clean teaware and tea leaves, requiring only one filter element group; when only boiling water, only two filter element groups are needed, as subsequent filter element groups add trace minerals, suitable only for brewing tea; when brewing tea, all three filter element groups are used simultaneously. Intelligent selection of the operating mode effectively reduces the frequency of filter element use, improves filtration efficiency, avoids waste, and extends the lifespan of the filter elements. This tiered filtration strategy not only optimizes water quality adaptability but also enables on-demand consumption of filter cartridges, significantly reducing maintenance costs and environmental burden.
[0031] In detail, there are two design options for the control component:
[0032] Firstly, the control component includes a first solenoid valve 31, a second solenoid valve 32, and a third solenoid valve 33 that are signal-connected to the second control module 16. The first solenoid valve 31 is arranged on the first branch channel 101, the second solenoid valve 32 is arranged on the second branch channel 102, and the third solenoid valve 33 is arranged on the third branch channel 103.
[0033] Secondly, the control component is a three-position four-way solenoid valve. The outlets of the three branch channels are respectively connected to the three inlets of the three-position four-way solenoid valve, and the outlet of the three-position four-way solenoid valve is connected to the water injection channel 20. That is, the aforementioned four-way pipe connection 19 can be replaced with a three-position four-way solenoid valve. For the specific structure, please refer to the patent scheme with patent number CN201310084997.9 and title "Integrated Dual-Electrically Controlled Three-position Four-way Medium-pressure Solenoid Valve". The two control schemes are respectively suitable for cost-sensitive and highly integrated application scenarios. The former is easier to maintain independently, while the latter has a compact structure and faster response.
[0034] As a preferred embodiment, the system also includes a first flow meter 41, a second flow meter 42, and a third flow meter 43. The first flow meter 41 is arranged on the first branch channel 101, the second flow meter 42 is arranged on the second branch channel 102, and the third flow meter 43 is arranged on the third branch channel 103. Alternatively, the second flow meter 42 can be arranged on the transition channel 121. The flow rate of the second branch channel 102 can be calculated by subtracting the data from the data of the second flow meter 42 and the third flow meter 43. All three flow meters are connected to the second control module 16 to collect the flow rate data of the three branch channels. The frequency and amount of use of each filter element group can be calculated from the data of each flow meter, thereby calculating the remaining service life of each filter element group. For example, the service life of the first filter element group 13 is the cumulative usage of Am. 3 If the total flow rate exceeds a certain value, it's considered a replacement point, avoiding the severe resource waste caused by replacing all filter cartridges in one maintenance cycle. Based on a lifespan prediction mechanism using real-time flow monitoring, filter cartridge replacement is transformed from "periodic mandatory" to "on-demand intelligent reminders," improving user experience and reducing unnecessary consumable expenses.
[0035] As a further preferred approach, a display screen unit 18 connected to the second control module 16 can be installed on the top of the water purifier 1 to display the lifespan of each filter element. Visual status feedback enhances system transparency and user trust, facilitates timely maintenance, and ensures long-term stable operation.
[0036] As a preferred embodiment, a booster pump 17 is also included, which is arranged on the inlet channel 12 or the transition channel 121. Since the water pressure of tap water itself is very limited, the booster pump 17 can make the water output more stable. The introduction of the booster pump effectively overcomes the impact of municipal water pressure fluctuations on filtration efficiency and water injection speed, ensuring the consistency and reliability of water supply in all operating modes.
[0037] Preferably, the first filter element group 13 includes at least one carbon fiber filter element. The second filter element group 14 includes at least one nanofiltration membrane filter element, and the third filter element group 15 includes at least one composite granular activated carbon filter element. Wherein:
[0038] Carbon fiber filter cartridge (first stage) performance characteristics: "Adsorption and coarse filtration". Its core feature is its strong adsorption capacity, which can quickly remove residual chlorine, discoloration, odor, and some organic matter (such as pesticide residues) from water, while filtering large particles such as sediment and rust. It primarily protects subsequent filter cartridges. Service life: Shortest, typically 6–12 months. Because it is the first to contact the raw water, its adsorption capacity saturates quickly, requiring regular replacement to prevent contaminant penetration.
[0039] Nanofiltration membrane filter cartridge (second stage) performance characteristics: "Intelligent selective filtration". Its pore size can trap bacteria, viruses, heavy metals (such as lead and cadmium), scale (calcium and magnesium ions), and large molecular organic matter. A key feature is its ability to retain some beneficial minerals (such as potassium and sodium ions), producing "mineral-purified water". Lifespan: Relatively long, typically 18–36 months. Lifespan is greatly affected by the effectiveness of pre-filter protection and water quality. Once clogged or damaged, purification performance will drop sharply.
[0040] Granular activated carbon filter cartridge (third stage) performance characteristics: "Taste Adjustment Master". It primarily performs deep adsorption, further removing any trace odors in the water and significantly improving its taste, making it sweeter and more refreshing. It is the final barrier to ensure delicious drinking water. Lifespan: Medium, typically 9–15 months. As a post-filter cartridge, its lifespan is longer than that of the pre-filter carbon fiber cartridge, but its adsorption capacity will decrease over time, affecting the taste. The three-stage filter cartridge combination forms a complete purification chain of "coarse filtration—fine filtration—conditioning", ensuring safety while also meeting the special water quality requirements for brewing tea (such as low chlorine, moderate minerals, and a sweet taste), truly achieving "water tailored to specific needs".
[0041] As a preferred embodiment, the operation panel 21 integrates a user input unit for user operation and information input. The user input unit includes at least one of a touchscreen and physical buttons. The user input unit has at least three function selections: cleaning, boiling water, and tea brewing. When the user inputs the cleaning function, the second control module 16 controls the first channel 101 to open and the other two channels to close. When the user inputs the boiling water function, the second control module 16 controls the second channel 102 to open and the other two channels to close. When the user inputs the tea brewing function, the second control module 16 controls the third channel 103 to open and the other two channels to close. This one-click, scenario-based operation greatly simplifies the user interaction process, allowing even non-professional users to easily obtain the optimal water quality to suit their current needs, reflecting the human-centered design concept of "smart home appliances."
[0042] The above descriptions are merely embodiments of the present invention, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the present invention or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
