Description

[0001] Priority application This application claims priority to Chinese Invention Patent Application No. [2026104919643] filed on April 14, 2026, entitled "[Target Ingredient Intake Detection Component, Intelligent Drinking Device and Intelligent Beverage Drinking Device]", which is incorporated herein by reference in its entirety. Technical Field

[0002] This invention belongs to the field of beverage health monitoring technology, and particularly relates to a target ingredient intake detection component, an intelligent drinking device, and an intelligent beverage drinking device. Background Technology

[0003] With the continuous improvement of public health awareness, dietary health management has become an increasingly important issue. Controlling the intake of components such as sugar, caffeine, and electrolytes in beverages is a crucial part of daily dietary health management. Especially for special groups such as those trying to lose weight, those with prediabetes or diabetes, and those focusing on anti-glycation skincare, accurately understanding the component content of beverages and their actual intake is a prerequisite for scientific dietary control. However, daily drinking scenarios are fragmented and diverse, with users' drinking behaviors covering multiple scenarios such as home, office, outings, and social gatherings. Drinking containers include various types such as personal water cups, bottled beverages, freshly made milk tea, and baby bottles. Existing technological solutions struggle to simultaneously meet the needs of multi-scenario adaptation, real-time accurate detection, and intake management.

[0004] Currently, existing technologies for detecting beverage components and monitoring consumption mainly fall into two categories: in vitro stand-alone detection devices and integrated smart drinking devices, as detailed below: The first category is in vitro stand-alone testing devices, mainly including test strips and professional testing equipment. For example, the mainstream portable beverage sugar detection solutions on the market currently include glucose test strips and professional digital saccharimeters. Among them, glucose test strips rely on enzymatic reactions to achieve qualitative or semi-quantitative detection of glucose. They can only achieve a rough judgment within a range, with extremely low detection accuracy. They have no practical reference value for detecting complex sugar components and other target components in beverages. At the same time, this type of product is a disposable consumable, resulting in high long-term usage costs. It can only achieve single-sample testing and cannot achieve continuous monitoring of the drinking process, nor can it calculate the user's actual intake based on the drinking volume. It completely fails to meet the user's long-term, daily sugar control management needs. While professional digital saccharimeters offer a certain level of quantitative detection accuracy, their complex operation requires multiple steps, including sampling, calibration, testing, and cleaning. This makes them unsuitable for real-time, seamless detection during consumption, and their poor portability makes them ill-suited for the immediate testing needs of outings and social situations. More importantly, these devices only measure the static saccharimeter value of beverages and cannot calculate the actual nutrient intake based on the user's actual consumption volume. Users only know the saccharimeter content but cannot accurately control their total intake, nor can they obtain corresponding drinking reminders and health guidance, thus failing to form a complete closed loop from detection to control.

[0005] The second category is integrated smart drinking devices, which integrate detection or measurement functions into drinking containers such as straws and cups to improve ease of use. Such solutions have been disclosed in existing technologies, for example, Chinese utility model patent CN223913881U discloses a smart straw that uses two sets of sensing electrodes on the straw to collect the time difference of liquid flowing through the electrodes, combined with the drinking time, and calculates the user's water intake based on the straw's cross-sectional area. This solution only achieves single-volume measurement of drinking, completely lacking the ability to detect target components such as sugar and caffeine in the fluid. It cannot determine the health attributes of the beverage consumed by the user, only knowing the volume, and cannot obtain data on the intake of components of core concern to the user, thus failing to meet the core needs of health management such as sugar control. Furthermore, its drinking volume calculation relies solely on a fixed coefficient, lacking self-calibration and temperature / viscosity compensation modules. The measurement accuracy is greatly affected by the user's drinking habits and the physical properties of the fluid, resulting in low data reliability. Moreover, it lacks corresponding tiered reminders and data synchronization functions, only achieving basic drinking volume recording, and cannot provide users with comprehensive health management services.

[0006] For example, Chinese utility model patents with publication numbers CN216822670U and CN216494693U disclose a smart cup and a sugar measuring cup, respectively. They integrate a sugar concentration detection module and a weight sensor inside the cup body, and calculate the total sugar content of the beverage in the cup by detecting the sugar concentration and overall weight of the liquid inside the cup. This type of solution has three major flaws: First, technically, it can only achieve static detection of the beverage inside the cup, and cannot achieve dynamic, real-time monitoring of the user's intake during drinking. It cannot accurately distinguish between the remaining amount in the cup and the user's actual intake, resulting in a significant deviation between the detection data and the user's actual intake. Second, structurally, all functional modules are integrated with the cup body, making them unremovable and incompatible with other drinking containers such as milk tea cups, mineral water bottles, and baby bottles. It can only be used in scenarios where users bring their own cups, such as at home or in the office, which severely limits its application. Third, functionally, it can only detect a single component, sucrose, and cannot cover multiple target components such as glucose, fructose, caffeine, and electrolytes. Furthermore, it lacks functions such as self-calibration, wireless data synchronization, and tiered reminders. It can only display basic data locally on the cup body and cannot achieve long-term health data tracking and personalized management.

[0007] For example, US patent application US20030111003A1 discloses a sugar / caffeine content indicator device that integrates color-developing materials such as glucose oxidase and xanthine oxidase into a straw or cup, determining the presence or absence of sugar or caffeine in a beverage through a color reaction. This solution can only achieve qualitative detection, unable to accurately measure the concentration of components, let alone calculate the user's actual intake, and completely fails to meet the core requirement of quantitative sugar control. Furthermore, its color-developing materials are disposable consumables, cannot be reused after the reaction, resulting in high long-term costs, and lack any data storage, communication, or feedback functions; it can only observe color changes with the naked eye, failing to record and track health data, thus limiting its practical value.

[0008] In summary, none of the existing solutions can simultaneously address the core technical problems of disconnect between testing and drinking scenarios, disconnect between component testing and intake measurement, single-function approach that fails to form a closed loop for health management, and poor scenario adaptability. These solutions are insufficient to meet users' core needs for real-time detection of beverage components and scientific management of intake across multiple daily scenarios. Summary of the Invention

[0009] The purpose of this invention is to provide a target ingredient intake detection component, an intelligent drinking device, and an intelligent beverage drinking device, which partially solves or alleviates at least one of the above-mentioned deficiencies in the prior art and is capable of detecting the intake of target ingredients in flowing liquids.

[0010] To solve the aforementioned technical problems, the present invention specifically adopts the following technical solution: A first aspect of the present invention is to provide a target component intake detection component, comprising a fluid cavity having an inlet and an outlet, a flow detection component for detecting the flow rate of liquid flowing through the fluid cavity, and a concentration detection component for detecting the concentration of the target component in the liquid flowing through the fluid cavity. It also includes a first liquid retention tank communicating with the fluid cavity for retaining liquid. The first liquid retention tank is accessible to the detection window of the concentration detection component, so that the detection window of the concentration detection component can continuously contact the liquid as the liquid flows through the fluid cavity. The first liquid retention tank is communicating with the fluid cavity and is a tapered groove that is wider at the outside and narrower at the inside. The bottom of the first liquid retention tank has a mounting hole, through which the detection window of the concentration detection component contacts the liquid in the fluid cavity. The concentration detection component includes: an optical cavity, a prism installed in the optical cavity, and a CCD sensor installed at the bottom of the optical cavity, wherein the prism and the mounting hole form the detection window; The liquid flow rate detected by the flow detection component and the concentration of the target component in the liquid detected by the concentration detection component are used to calculate the content of the target component.

[0011] Furthermore, the component also includes two transducer channels disposed on the wall of the fluid cavity and communicating with the fluid cavity, wherein the center lines of the two transducer channels coincide and form an acute angle with the center line of the fluid cavity; The flow detection component is an ultrasonic flow meter, which includes a transmitting ultrasonic transducer and a receiving ultrasonic transducer respectively disposed on two transducer beam channels, so that the ultrasonic waves emitted by the transmitting ultrasonic transducer can radially pass through the fluid cavity and are finally received by the receiving ultrasonic transducer.

[0012] Furthermore, the fluid cavity includes a fluid channel with a circular cross-section; or, the fluid cavity includes a fluid channel with a square or rectangular cross-section; and / or, the first liquid retention tank is a conical tank that is wider on the outside and narrower on the inside.

[0013] Further: The content of the target component is calculated using the formula m=ρ*v*k; where m is the mass of the target component; ρ is the concentration of the target component; v is the liquid volume, calculated based on the liquid flow rate; and k is a correction factor.

[0014] A second aspect of the present invention is to provide an intelligent drinking device, comprising a first housing for encapsulation, and a target ingredient intake detection component located at the center of the first housing, as described in any of the preceding claims. It also includes a main control circuit board located on one side of the target ingredient intake detection component; the main control circuit board is provided with a chipset and a power interface; a first battery for power supply is located on the other side of the target ingredient intake detection component and is electrically connected to the power interface on the main control circuit board; The target component intake detection component is provided with an inlet pipe interface on the inlet and an outlet pipe interface on the outlet. The first housing is divided into a first sub-housing and a second sub-housing that can be assembled; wherein the first sub-housing covers the top of the target ingredient intake detection component and the second sub-housing covers the bottom of the target ingredient intake detection component; and a button component is provided on the second sub-housing and a light-emitting element is provided on the first housing.

[0015] Furthermore, the device also includes a second housing fitted inside the first housing, the second housing including a third sub-housing and a fourth sub-housing that can be assembled and are arranged opposite to each other; the fourth sub-housing covers one side of the main control circuit board.

[0016] A third aspect of the present invention is to provide an intelligent beverage drinking device, comprising the intelligent drinking device described above; the inlet port of the intelligent drinking device is connected to a guide tube for extending into the fluid cavity, and the outlet port of the intelligent drinking device is connected to a suction tube for generating negative pressure.

[0017] Furthermore, a first connecting tube segment and a transparent tube segment are sequentially arranged between the guide tube and the suction tube, and the guide tube, the first connecting tube segment, the transparent tube segment and the suction tube are integrally formed to form an integral detachable suction tube; When the integrated detachable straw passes through the fluid cavity, the transparent tube segment is located inside the fluid cavity, and the transparent tube segment is made of a light-transmitting material.

[0018] Furthermore, the size of the first connecting pipe section gradually decreases from top to bottom, and correspondingly, the size of the guide channel inside the liquid inlet pipe interface also gradually decreases from top to bottom.

[0019] Furthermore, a second connecting tube segment is integrally formed between the suction tube and the transparent tube segment, and the size of the second connecting tube segment gradually increases from top to bottom.

[0020] Beneficial effects: All existing portable sugar testing solutions involve static sampling and testing before drinking, which can only determine the basic sugar content of the beverage and cannot track the actual intake of a single user in real time. Users often only realize that they have exceeded the sugar intake limit after finishing the whole cup, which is irreversible. This invention integrates the detection components completely into the beverage's flow path, and simultaneously completes flow measurement, concentration detection, and intake calculation during the user's drinking process.

[0021] Furthermore, a feedback module is also set up, such as a light-emitting device to provide tiered reminders. For example, the intake progress can be fed back in real time through three levels of green, yellow and red lights, so that users can actively adjust their drinking behavior according to the reminders during the drinking process, and truly achieve proactive intervention in sugar control management.

[0022] Furthermore, this invention employs an ultrasonic flow sensor, which, compared to commonly used turbine flow sensors, has no directly moving parts, reducing problems such as clogging and jamming, and significantly improving cleaning efficiency. Existing portable flow measurement methods (such as turbine flow meters) are typically only suitable for pure water or low-viscosity beverages. They are prone to jamming in everyday beverages containing solid impurities such as fruit pulp particles and tea leaves, and are difficult to clean. The ultrasonic flow sensor effectively overcomes the limitation of existing turbine flow sensors, which are only suitable for pure water or low-viscosity beverages. This ultrasonic flow sensor can be adapted to everyday drinking straws, overcoming the limitations of existing ultrasonic flow sensors, which are mostly large-diameter, large-volume, and unsuitable for portable everyday drinking devices. At the same time, by combining the ultrasonic flow sensor with a target component concentration detection component, compared to existing ultrasonic flow sensors that can only measure liquid flow, the addition of liquid target component concentration detection function further expands its application scenarios.

[0023] Furthermore, this invention employs a refractive index sensor, which significantly reduces the size compared to commonly used refractometers, directly improving the user's interaction with the sensor and enhancing the user experience. Users no longer need to use droppers to draw liquid, add it to the sample chamber, manually start the measurement, manually calibrate, or manually clean it after use. This refractive index sensor can be adapted to everyday drinking straws, overcoming the limitations of existing refractive index sensors, which are mostly used in the form of refractometers and lack real-time detection of target component concentration and real-time measurement of intake. At the same time, by combining the refractive index sensor with an ultrasonic flow sensor, compared to existing refractometers that can only perform single, manual liquid target component concentration measurements, this invention adds real-time, automatic liquid target component concentration detection and intake measurement functions, further expanding application scenarios and improving the user experience.

[0024] Furthermore, this invention provides two forms: a combination of a circular fluid channel and a separate detachable straw for the fluid chamber, and an optional combination of a square or rectangular fluid channel and an integrated detachable straw for the fluid chamber, to meet the needs of different users for convenient cleaning and compact structure. In the form of an integrated detachable straw, the liquid is completely confined inside the straw, and there is no liquid in the fluid chamber. The detection window can indirectly contact the liquid through the specially designed integrated detachable straw for measurement. Combined with the non-contact characteristics of the ultrasonic flow sensor, this achieves completely non-contact detection of the target ingredient intake. Regardless of the form used, the target ingredient intake detection component of this invention significantly improves cleaning efficiency compared to existing contact measurement solutions. In addition, since there are no moving parts inside the component, the risk of straw blockage or jamming is greatly reduced.

[0025] Furthermore, the target ingredient intake detection component provided by this invention simplifies the process compared to existing methods that require users to search online for the content of target ingredients in beverages, verify the authenticity of information, and observe and estimate their own intake. It significantly reduces the number of steps required, allowing users to simply drink as they would with a regular straw to instantly obtain the concentration and intake amount of the target ingredient. Users can also access the complete experience through a companion application. For example, for users who need to control their sugar intake, this component not only informs them of the sugar content in their beverage but also clearly indicates the recommended amount based on their sugar control goals, allowing them to enjoy the beverage without compromising their sugar control. If users don't want to waste their beverage, the component will inform them how much their daily sugar intake exceeds their target and provide specific and simple exercise methods to burn off the excess sugar.

[0026] This invention completely replicates the usage of ordinary straws. Users only need to suck up the straw like they would with a regular straw to automatically complete all detection, calculation, and reminder functions without any additional operation or learning cost. It can be easily used by people of all ages. At the same time, there are no disposable consumables, the main body can be reused for a long time, and only the tubing can be replaced as a low-cost consumable. The long-term cost is greatly reduced, and it can be adapted to all scenarios such as home, travel, social, and dining. Attached Figure Description

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] In this document, "and / or" includes any and all combinations of one or more of the listed related items.

[0035] In this article, "multiple" means two or more, that is, it includes two, three, four, five, etc.

[0036] Example 1: As Figures 1-2 As shown, this embodiment provides a target ingredient intake detection component 206, which is applied to the real-time and dynamic detection of beverage flow rate and target ingredient concentration during beverage consumption. The concentration of the target ingredient changes in real time due to factors such as gravity or the addition of ice during the drinking process, thus requiring real-time detection.

[0037] Its specific structure includes a fluid cavity with an inlet and an outlet, a flow detection component 301 for detecting the flow rate of liquid flowing through the fluid cavity, and a concentration detection component 302 for detecting the concentration of a target component in the liquid flowing through the fluid cavity. The liquid flow rate detected by the flow detection component 301 and the concentration of the target component in the liquid detected by the concentration detection component 302 are used to calculate the intake of the target component.

[0038] The purpose of this invention is to integrate fluid flow metering and target component concentration detection into the essential flow channel of a beverage, enabling synchronous, dynamic, and continuous collection of flow and component concentration data for each sip during the user's drinking process. This allows for accurate calculation of the user's actual intake of the target component through algorithms. For example, a control module with calculation capabilities can be set up or integrated into the flow monitoring component, thereby calculating the content of the target component based on the liquid flow rate and the target component concentration, which is essentially the amount of the target component ingested by the user when drinking the beverage.

[0039] This component is designed specifically for liquid beverage consumption scenarios and is compatible with all beverage intake behaviors achieved through negative pressure suction, gravity diversion, etc. It can be directly embedded in various drinking carriers such as smart straws, smart water cups, smart baby bottles, sports water bottles, and dedicated testing devices for freshly made beverages. The target detected components can cover free sugars, glucose, fructose, sucrose, caffeine, electrolytes, proteins, alcohol, etc., which are of core concern to users in daily beverages. It is suitable for the intake control needs of people who are trying to lose weight, diabetic patients, mothers and infants, and those who manage their healthy diet.

[0040] Specifically, after collecting the liquid flow rate and target component concentration, the target component content can be calculated using the formula m=ρ*v*k (the target component content calculated here refers to the target component content in the liquid consumed by the user in a single drinking session, that is, the amount of target component ingested by the user in a single drinking session); where m is the target component content (actually refers to the mass of the target component); ρ is the target component concentration, which is also the real-time concentration in the liquid consumed by the user in a single drinking session; V is the liquid volume, calculated based on the liquid flow rate (the liquid volume calculated here refers to the real-time liquid volume ingested by the user in a single drinking session); k is a correction coefficient, which is a comprehensive compensation parameter including temperature correction coefficient, viscosity correction coefficient, and flow channel loss correction coefficient, used to eliminate detection errors caused by the physical characteristics of the beverage, environmental factors, and structural losses. Through prior calibration and dynamic updates of real-time collected temperature and viscosity data, the calculation accuracy is ensured.

[0041] The memory chip of this component has pre-stored refractive index-concentration characteristic curve models for different types of detected components. Users can select different detected components, and the main control circuit board can call the corresponding calculation model according to the user's selection.

[0042] This component is embedded in a food-grade straw to form a portable smart straw. Users can drink milk tea, bottled beverages, or freshly made drinks without any additional operation. The system can detect sugar intake in real time during the drinking process and alert users with lights and vibrations when sugar intake exceeds the limit. It is a portable tool for young people, people who are trying to lose weight, and people who are controlling their sugar intake to detect the intake of target ingredients.

[0043] This component is integrated into the spout and water outlet of a water cup, making it suitable for daily drinking water and homemade beverage testing in home and office settings. It can track daily sugar and electrolyte intake over a long period and generate health management reports.

[0044] This component is integrated into the nipple channel of a baby bottle to monitor the sugar and protein intake of infant formula in real time, scientifically manage the amount of food fed to infants, avoid overfeeding, and meet the needs of refined management of maternal and infant feeding.

[0045] This component can be integrated into drinking devices specifically designed for patients with diabetes, kidney disease, and metabolic disorders, providing them with accurate dietary intake data to assist in clinical treatment and rehabilitation management, and offering healthcare professionals real and continuous patient dietary data support.

[0046] This component can be used as a complementary tool for tea and beverage brands, providing consumers with real-time visualized data on beverage ingredients. The results of this data enable users to understand the health attributes of freshly made beverages and also enhance brand trust among consumers.

[0047] like Figures 5-6 As shown, the target component intake detection component 206 further includes a second liquid retention tank 603 communicating with the fluid cavity for retaining liquid. The second liquid retention tank 603 reaches the detection window of the concentration detection component 302, so that the detection window of the concentration detection component 302 can continuously contact the liquid as the liquid flows through the fluid cavity. The second liquid retention tank 603 is communicating with the fluid cavity and is a tapered groove that is wider at the outside and narrower at the inside. The bottom of the second liquid retention tank 603 has a mounting hole, through which the detection window of the concentration detection component 302 contacts the liquid in the fluid cavity.

[0048] The second liquid retention tank 603 is an auxiliary structure in the target component intake detection component 206, specifically designed for intermittent, non-continuous, pulsating flow scenarios of daily beverage consumption, to ensure that the concentration detection component 302 can achieve continuous and stable detection, high-precision data acquisition, and uninterrupted response.

[0049] In everyday beverage consumption scenarios, users' drinking behavior is not a continuous constant flow, but rather a typical discontinuous pattern of "intermittent suction-pause-re-suction". After taking a sip of beverage, users will pause for several seconds to several minutes before taking another sip. During this process, the fluid chamber will repeatedly switch between full flow, emptying, and full flow again.

[0050] After the fluid in the fluid chamber is emptied, the detection window of the concentration detection component 302 is directly exposed to the air, making it impossible to continuously collect concentration data. This not only results in the loss of information on beverage concentration changes during intermittent periods but also prevents continuous monitoring throughout the entire drinking process. The pulsating and turbulent flow within the fluid chamber generates a large number of bubbles, which adhere to the surface of the detection window, causing signal distortion. Simultaneously, the repeated switching between liquid immersion and air exposure by the detection window leads to condensation, wall adhesion, and baseline drift, directly doubling the detection error and even resulting in meaningless jumps in data. Furthermore, each time the user re-absorbs fluid, the detection window needs to re-complete the liquid immersion, baseline calibration, and signal stabilization process, resulting in a response delay of hundreds of milliseconds to several seconds. This prevents synchronous acquisition with the flow detection component 301, ultimately leading to a desynchronization between concentration and flow data.

[0051] The second liquid retention tank 603 is an integrated branch groove structure with the fluid chamber. The tank opening is connected to the fluid chamber, ensuring that the liquid in the tank and the beverage in the main channel are always in communication and have completely identical concentrations. The second liquid retention tank 603 is located on the side wall of the fluid chamber, directly opposite the mounting position of the concentration detection component 302.

[0052] The cross-section of the second liquid retention tank 603 is an inverted conical structure that is wider on the outside and narrower on the inside. That is, the width of the end of the tank that is connected to the fluid cavity is large, and the width of the bottom end of the tank near the detection window is small. The side wall of the tank body tapers smoothly from the opening to the bottom of the tank.

[0053] The second liquid retention tank 603 features a tapered structure that is wider at the outside and narrower at the inside. Combined with the surface tension of the liquid, this increases the contact area between the liquid and the component detection window. Simultaneously, the surface tension increases the liquid residence time, ensuring continuous contact between the detection window and the liquid. Furthermore, the liquid is still affected by gravity and flows back into the pipeline, preventing it from remaining in the liquid retention tank for extended periods and ensuring continuous refresh of the liquid within the second liquid retention tank 603.

[0054] In addition, the wide slot allows the fluid in the main channel to enter the tank smoothly, while the tapered tank can buffer and rectify pulsating and turbulent flow, making the fluid entering the detection window at the bottom of the tank stable and without fluctuations. At the same time, the tapered structure can guide the air bubbles in the tank to rise and be discharged towards the wide slot, preventing the air bubbles from being stuck on the surface of the detection window at the bottom of the tank.

[0055] The narrow inner bottom design minimizes the dead volume of the tank, retaining only enough liquid to completely cover the detection window. This ensures testing requirements are met while preventing large amounts of beverage from remaining inside and being unable to drain. The tapered tank focuses the detection signal onto the detection area at the bottom, reducing light scattering and signal interference. This results in a more concentrated signal and a higher signal-to-noise ratio, further improving the accuracy of concentration detection.

[0056] The second liquid retention tank 603 has a through mounting hole at the center of its bottom. The diameter of the mounting hole matches the size of the detection window of the concentration detection component 302, ensuring that the effective sensing surface of the detection window is exposed to the liquid in the retention tank through the mounting hole, achieving unobstructed and full contact with the beverage.

[0057] When a user draws in a beverage using negative pressure, the fluid flows from the inlet into the fluid chamber, along the flow path to the outlet, and is ultimately ingested into the user's mouth. As the fluid flows through the indwelling tank, under the influence of fluid dynamic pressure and surface tension, it instantly fills the entire conical indwelling tank, completely covering the detection window and ensuring full contact between the window and the liquid. The fluid within the fluid chamber continues to flow, and the liquid in the indwelling tank and the beverage in the fluid chamber are continuously circulated and refreshed through the wide opening, ensuring that the concentration of the target components in the liquid within the tank is almost perfectly synchronized with the concentration of the beverage being ingested by the user within the fluid chamber.

[0058] After the user stops aspiration, the fluid in the fluid chamber, including the liquid in the conical indwelling tank, will be completely emptied by gravity. The component concentration detection workflow only performs real-time detection during the user's aspiration process. This is because the liquid is only updated and ingested by the user during aspiration, and the relatively fast detection speed allows for accurate real-time detection without prolonged liquid retention in the indwelling tank, eliminating the need for continuous detection and concerns about detection interruption. Furthermore, the raw data acquired through real-time monitoring lays the foundation for the subsequent construction of an adaptive adjustment mechanism. The system can dynamically optimize the detection frequency and response speed based on the user's drinking habits and the evolution trend of component concentration, significantly reducing system power consumption while ensuring measurement accuracy, achieving decoupled optimization between measurement performance and energy management.

[0059] Similarly, changes in liquid concentration during the interval do not need to be detected. When the user does not ingest liquid, changes in liquid concentration will not affect the real-time measurement results when the user ingests liquid later. Therefore, there is no need to establish a measurement baseline. It is only necessary to perform real-time measurements during the user's real-time beverage ingestion to update the concentration changes.

[0060] like Figures 3-4 As shown, in some embodiments, the flow detection component 301 is a turbine flow meter; the turbine flow meter includes an impeller 404 disposed within a fluid cavity 408, the impeller 404 being driven to rotate by the liquid as it flows through the fluid cavity 408; it also includes a magnet 405, such as a magnetic ring, that rotates with the impeller 404, and a flow sensor 402 for sensing the rotation of the magnet 405; the flow sensor 402 calculates the liquid flow rate based on the rotational speed of the impeller 404. Correspondingly, the fluid cavity 408 is cylindrical, and the inlet and outlet are disposed on the annular surface of the cylindrical fluid cavity 408.

[0061] Specifically, the fluid cavity 408 is formed by a bottom shell and an end cap; the bottom shell and end cap are made of food-grade polypropylene. A sensor mounting bracket 403 is provided between the bottom shell and the end cap for mounting the flow sensor 402. The mounting bracket 403 has a mounting groove that matches the thickness of the flow sensor 402 to ensure precise positioning of the sensor sensing surface and the magnetic ring 405. A sealing step is provided at the groove opening for mounting a sealing gasket to achieve waterproof protection.

[0062] The impeller 404 includes a rotating shaft and metering blades evenly distributed on the outside of the rotating shaft. The two ends of the rotating shaft are supported by bearings 406 on the bottom shell and the inner side of the end cover, respectively. The bearings 406 are embedded in the bearing mounting groove 608. The metering blades are made of lightweight food-grade plastic or food-grade elastic plastic / ceramic metering blades, and there are 5-9 blades. A magnetic ring 405 is attached to the root of the blade. When the fluid flows through the fluid cavity, it pushes the metering blades to drive the rotating shaft to rotate. The magnetic ring 405 rotates synchronously with the impeller 404 to realize dynamic sensing of flow rate.

[0063] In this embodiment, the flow sensor 402 is a Hall sensor chip embedded in the sensor mounting bracket 403. The distance between its sensing surface and the magnetic ring 405 is controlled at 1-2 mm. When the magnetic ring 405 rotates with the impeller 404 and passes the flow measurement sensor 402, the sensor outputs a pulse electrical signal. The fluid volume is accurately measured by counting the number of pulses. The opening of the sensor mounting slot 403 is sealed by a sensor sealing cover 401. A silicone sealing ring is provided at the connection between the sensor sealing cover 401 and the sensor mounting slot 403 to form a waterproof sealing structure, ensuring the watertightness of the flow measurement component 301.

[0064] In addition, traditional turbine flow meters generally adopt a radial inlet (fluid impacts impeller 404 radially and vertically along the cavity) or axial inlet (fluid impacts impeller 404 axially along the cavity). When the fluid is radially or axially inlet, the fluid can only impact a local blade on one side of impeller 404. The kinetic energy of the fluid at extremely low flow rates is insufficient to overcome the static friction of impeller 404. When the user slowly sips the fluid, impeller 404 does not rotate, resulting in metering errors.

[0065] To address the aforementioned issues, in this embodiment, a bend 602 is provided at the liquid inlet, ensuring that the direction in which the liquid enters the fluid cavity 408 is tangential to the annular surface of the fluid cavity 408. The outlet end of the bend 602 seamlessly connects to the annular sidewall of the cylindrical fluid cavity 408, and the central axis of the outlet end coincides with the tangential direction of the cylindrical fluid cavity 408 at the connection point. This ensures that after the fluid flows out of the bend 602, it completely enters the cavity along the tangential direction of the inner wall of the cavity, directly impacting the impeller 404, thereby achieving lightweight start-up of the impeller 404.

[0066] Everyday beverages are not just water, but also include milk tea, fruit tea, coffee, dairy products, etc., which generally contain solid impurities such as tea base, fruit pieces, coconut jelly particles, coffee grounds, and milk powder sediment, which can easily cause the impeller to get stuck.

[0067] To solve the problem of stagnation, such as Figures 5-6 As shown, the fluid cavity 408 has an anti-jamming groove 604 at its outlet. The annular swirling flow formed by the tangential liquid inlet gathers solid particles from the beverage towards the outer ring of the inner wall of the cavity. The particles flow circumferentially along the inner wall with the swirling flow, eventually reaching the inlet of the anti-jamming groove 604 at the outlet. When the particles reach the groove inlet, they smoothly enter the groove along the arc-shaped bevel. Because the depth of the groove is greater than the gap between the impeller 404 and the inner wall, the particles, after entering the groove, are completely removed from the rotating sweeping area of ​​the impeller 404 blades and will not be carried into the gap by the blades, thus completely avoiding the risk of jamming. The outlet of the groove is completely connected to the outlet. The fluid continuously drawn by the user will carry the particles in the groove directly out of the cavity from the outlet along the flow channel, into the dispensing straw, and finally ingested by the user, without remaining or accumulating in the groove.

[0068] The inlet and outlet of the fluid chamber are respectively connected to the inlet pipe interface 607 and outlet pipe interface 606 on the bottom shell, facilitating a sealed connection with the inlet and outlet pipes. A vibration actuator mounting slot 601 is provided in the middle section of the bottom shell, which is used to mount a miniature vibration actuator and a miniature speaker.

[0069] The bottom shell sidewall is provided with a mounting surface 605 for mounting the main body of the concentration detection component. The mounting hole at the bottom of the second liquid retention tank 603 leads to the mounting surface 605, facilitating the installation of the concentration detection component 302.

[0070] like Figure 8 As shown, in some other embodiments, the flow detection component 301 is an ultrasonic flow meter; the fluid cavity 408 is a cylindrical channel, and the inlet and outlet are respectively located at both ends of the cylindrical fluid cavity 408; the ultrasonic flow meter includes a transmitting end and a receiving end respectively located on both sides of the fluid cavity 408, so that ultrasonic waves can pass through the fluid cavity 408 radially.

[0071] Replacing turbine flow meters with ultrasonic flow meters allows for smaller equipment sizes and eliminates the problem of impeller jamming (404 stainless steel).

[0072] In addition, if an ultrasonic flow meter is used, the aforementioned bend in the pipe that connects to the fluid cavity is not required. The entire flow detection area is designed to be directly through, without the need for special design of bends, impellers, and their fluid cavities. However, the liquid retention tank design still needs to be retained, or other structural designs can be used to achieve the same liquid retention function. In any case, using an ultrasonic flow meter will greatly reduce the overall size of the flow measurement component, and there is no design in the pipe that obstructs the flow of fluid. The sensing components are all embedded inside the outer wall of the pipe component, achieving completely non-contact measurement.

[0073] The ultrasonic transmitter and receiver are designed to face each other, and are on a straight line. The tilt angle has a certain range and can be adjusted according to different needs. For example, they can both be at a 30-degree angle to the straight pipeline but in opposite directions. One can be installed upstream and the other downstream. Both can be used as transmitters or receivers at the same time. Therefore, there is no fixed requirement for the transmitter or receiver to be installed upstream. Both are acceptable.

[0074] In addition, since the fluid cavity 408 is a cylindrical straight channel with two ends, the inlet and outlet are located at the two ends of the cylindrical fluid cavity 408. The inlet connects to the inlet guide tube inserted into the beverage, and the outlet connects to the outlet nozzle tube that the user holds in their mouth. This forms a completely axial straight flow path of inlet tube, inlet, cylindrical straight cavity, outlet, and outlet tube, without any obstruction structure. The fluid flow resistance is reduced to a minimum, and the user can drink by gently sucking, which is suitable for the drinking needs of all people.

[0075] Of course, the flow detection component can also be an ultrasonic sensor, a differential pressure sensor, a weight sensor, or a thermal flow sensor; this invention does not impose any specific limitations.

[0076] In this embodiment, the concentration detection component can be at least one of an optical detector, an electrochemical detector, and a biosensor.

[0077] like Figures 7-9 This demonstrates combinations of different flow detection components and different concentration detection components: Figure 7 The medium flow rate detection component is a turbine flow meter, and the concentration detection component is a near-infrared concentration detector; Figure 8 The flow detection component is an ultrasonic flow meter, and the concentration detection component is an optical concentration detector; Figure 9 The medium flow rate detection component is an ultrasonic flow meter, and the concentration detection component is a near-infrared concentration detector.

[0078] like Figure 4 As shown, the optical concentration detector 302 mainly includes an optical cavity 501, an LED lamp 502, a prism 503, and a CCD sensor 504. Each component adopts an integrated packaging design to ensure detection accuracy and sealing performance.

[0079] The optical cavity 501 is made of food-grade polypropylene (PP). The depth of the optical cavity 501 is adapted to the size of the prism 503. A circular food-grade silicone sealing ring is attached to the center of the contact surface of the prism 503 to form a waterproof seal with the small amount of fluid temporarily stored in the second liquid retention tank 603. The outer side of the optical cavity 501 is provided with a positioning boss to precisely match the mounting slot of the core functional module 206 to ensure that the detection window is aligned with the second liquid retention tank 603 section of the fluid cavity.

[0080] LED 502 is a light-emitting diode with a wavelength range of 570-610nm. Its light-emitting end faces prism 503 and is used to emit detection light. Prism 503 is made of high-transmittance quartz glass and has a trapezoidal structure. It is fixed inside the optical cavity 501 and is used to refract the light emitted by LED 502 into the fluid and guide the reflected / absorbed light from the fluid to CCD sensor 504. CCD sensor 504 is precisely aligned with the light-emitting end of prism 503 and is used to collect optical signals. Its refractive index measurement range is 1.2-1.8, which can accurately identify the concentration of target components such as soluble solids in the fluid.

[0081] like Figure 14 As shown, the accuracy of four different portable sugar testing methods was verified. The official sugar content listed on the beverage packaging ingredient list was used as a reference. Finally, the error rates of different methods were compared to verify the detection performance of the smart detection straw.

[0082] Example 2: like Figures 10-12 As shown, this embodiment also provides a smart drinking device 102, including the target ingredient intake detection component 206 described in Embodiment 1; it also includes a support circuit board 205 and a separate circuit board 207 disposed on both sides of the target ingredient intake detection component 206; the support circuit board 205 is provided with a chipset and a power interface, and the separate circuit board 207 is provided with a light-emitting component 208; the support circuit board 205 and the separate circuit board 207 are connected for power supply and communication via a flexible ribbon cable; a second battery 204 for power supply is disposed on the outside of the support circuit board 205 and connected to the power interface on the support circuit board 205; The target component intake detection component 206 is provided with an inlet pipe interface on the inlet and an outlet pipe interface on the outlet. It also includes a housing for encapsulation, which is divided into a first housing and a second housing that can be assembled; wherein the first housing covers the side of the supporting circuit board 205 and the second housing covers the side of the split circuit board 207; the first housing is provided with a charging port and the second housing is provided with a transparent window 201 corresponding to the position of the light component.

[0083] The drinking carrier unit of the intelligent drinking device 102 can be a straw, a mouthpiece, a small drinking tube, a water bottle, a cup-shaped drinking vessel, a liquid container, or a food container, suitable for use in home, office, and outing scenarios. The intelligent drinking device 102 can be made of plastic, glass, and / or metal, and all parts that come into direct contact with the fluid are made of food-safe materials. The intelligent drinking device 102 can be of various sizes to suit different drinking needs. When the drinking carrier unit of the intelligent drinking device 102 is a straw, feedback signals (including but not limited to light, voice, or vibration) can indicate the user's progress toward the target ingredient content and / or intake amount or the status of the intelligent straw. When the drinking carrier unit of the intelligent drinking device 102 is a smart water bottle or a cup-shaped drinking vessel, the feedback signal can indicate the content and / or consumption of the target ingredient in the container. When the drinking carrier unit of the intelligent drinking device 102 is a liquid container or a food container, the feedback signal can indicate the concentration of the target ingredient in the contents and the consumption information.

[0084] The target ingredient intake detection component 206, located at the axial center of the entire unit, serves as the core for data acquisition and structural support. It is the channel through which the beverage flows and the execution unit for flow measurement and concentration detection. It is compatible with both turbine and ultrasonic flow detection methods, as well as optical and near-infrared concentration detection methods, adapting to the needs of different beverage scenarios. The overall structure is symmetrically arranged around the detection component, maximizing the use of the spherical space inside the casing to achieve a miniaturized design.

[0085] The entire unit features a compact layout to accommodate the straw, with the center occupied by the fluid cavity. A single board cannot simultaneously accommodate the layout of the main control chip, power supply, and feedback components. The dual-board symmetrical design maximizes the use of the internal space of the housing, shortens electrical wiring, reduces interference from the power circuit to the detected analog signal, and achieves functional separation of the main control and feedback, facilitating modular assembly and subsequent maintenance.

[0086] The support circuit board 205 is the control and power supply hub of the entire device. It is fixed to one side of the target component intake detection component 206, with its surface parallel to the fluid cavity axis. It is precisely positioned and fixed to the first housing and the detection component via positioning posts, and is completely enclosed and protected by the first housing. The chipset soldered onto the support circuit board 205 includes a control module chip, a storage chip, a power management chip, a Bluetooth communication chip, and a power interface. The control module chip, as the core processing unit, is electrically connected to all functional components on the board, responsible for data reception, processing, calculation, and command transmission. The storage chip stores calibration curves, user-preset thresholds, detection data, and other information. The power management chip manages the voltage, current, and low power consumption of the second battery 204, providing a stable operating voltage for all components. The Bluetooth communication chip interacts with external smart devices, and its external antenna is arranged along the edge of the board. A Type-C charging interface is located on the side wall of the first housing and is electrically connected to the second battery 204. A silicone dust plug is provided at the charging interface to further enhance waterproof protection.

[0087] The second battery 204 is located on the outside of the support circuit board 205, that is, in the cavity between the support circuit board 205 and the first housing. It is directly connected to the power interface on the support circuit board 205, maximizing the use of the unused space inside the housing without increasing the overall size of the device.

[0088] The separate circuit board 207 is a support circuit board for the component concentration detection sensor. (It is worth noting that if a near-infrared sensor is used instead of a refractive index sensor, the separate circuit board 207 is no longer needed because the near-infrared sensor itself has a circuit board and is very small.) The separate circuit board 207 and the support circuit board 205 are symmetrically fixed on the other side of the detection assembly. The board surface is parallel to the axial direction of the fluid cavity and is attached to and fixed to the inner wall of the second housing, and is completely sealed and protected by the second housing.

[0089] The light-emitting component 208 consists of one or more RGB full-color LEDs, which are evenly arranged along the circumference of the board and precisely aligned with the transparent window 201 on the second housing. It can emit light of different colors such as red, yellow, and green, as well as different flashing modes at different frequencies, corresponding to different ranges of user intake, to achieve graded visual reminders.

[0090] The inlet and outlet interfaces are respectively located at both ends of the fluid cavity of the target component intake detection component 206, corresponding one-to-one with the inlet and outlet, and arranged coaxially to form a through fluid channel. This enables quick sealing connection between the device and the inlet guide tube (e.g., the straw section inserted into a beverage) and the outlet nozzle tube (e.g., the section for the user to drink from). It can be directly connected in series with a regular drinking straw to form a complete smart straw, and can also be adapted to various drinking media to achieve full-scenario compatibility.

[0091] In this embodiment, the first housing covers the side supporting the circuit board 205 and the second battery 204, and the inner wall is provided with positioning posts for the supporting circuit board 205, a fixing compartment for the second battery 204, and a charging port mounting hole. The second housing covers the side of the split circuit board 207, and the inner wall is provided with positioning grooves for the split circuit board 207 and a limiting structure for the light-emitting component 208 to ensure that the light-emitting component 208 is aligned with the transparent window 201. A transparent window 201 corresponding to the position of the light-emitting component is opened on the housing. The window is made of a high-transmittance food-grade material, which can uniformly transmit LED light and achieve waterproof sealing. The window can be designed as a circle, ring, or strip to adapt to different light-emitting patterns and improve visual recognition.

[0092] The first and second housings are fitted with matching male and female snap-fit ​​structures at their mating edges, enabling detachable assembly. They can also be adapted to ultrasonic welding, threaded connections, magnetic connections, and other methods. A closed-loop waterproof sealing groove is provided at the mating edge, with an embedded food-grade silicone waterproof sealing ring. After the housings are assembled, the sealing ring is evenly compressed to form an IPX7 waterproof seal, which can withstand daily water rinsing and short-term immersion without the risk of leakage. The connection between the inlet / outlet pipe interface and the housing is also equipped with a sealing structure to achieve seamless waterproofing throughout the entire cavity.

[0093] The shell is injection molded from food-grade ABS / PP material, possessing excellent structural strength, impact resistance, and corrosion resistance. The surface has a matte, skin-friendly finish, providing a good grip and preventing slippage. All parts that come into contact with users and beverages comply with national food safety standards, with no harmful substances leaching out.

[0094] In some embodiments, both the first housing and the second housing are hemispherical, and the first housing is further divided into a first sub-shell 202 and a second sub-shell 203 that can be assembled, forming a hierarchical detachable structure.

[0095] In this embodiment, the chipset calculates the target component content based on the liquid flow rate and target component concentration detected by the target component intake detection component 206, and compares it with a preset threshold. If the target component content is less than a first threshold percentage, the light-emitting component 208 is controlled to issue a first warning; if the target component content is greater than or equal to the first threshold percentage and less than a second threshold percentage, the light-emitting component 208 is controlled to issue a second warning; if the target component content is greater than or equal to the second threshold percentage and less than a third threshold percentage, the light-emitting component 208 is controlled to issue a third warning; and if the target component content is greater than or equal to the third threshold percentage, the light-emitting component 208 is controlled to issue a fourth warning.

[0096] The preset threshold is the upper limit of the target ingredient intake set by the user in advance. It can be set through external smart devices such as mobile APP and stored synchronously in the memory chip of the supporting circuit board 205 through the wireless communication module, and can be called by the chipset in real time.

[0097] More specifically, the first interval is 30% less than the first threshold, which is the safe intake range. The intake is far below the upper limit and there is no health risk. The first warning is a solid green light. The second interval is 70% less than the second threshold and 30% or more than the first threshold. This is the warning intake range. The intake is close to the upper limit and the drinking rate needs to be controlled. The second warning is a solid yellow light. The third interval is 90% less than the third threshold and 70% or more than the second threshold. This is the borderline exceeding range. The intake is about to reach the health upper limit and caution is needed. The third warning is a solid red light. The fourth interval is 90% or more than the third threshold. This is the exceeding range. The intake is about to exceed the health upper limit and drinking needs to be stopped. The fourth warning is a flashing red light.

[0098] Example 3: like Figure 13 As shown, this embodiment provides an intelligent beverage drinking device 100, including the intelligent drinking device 102 described in Embodiment 2; the liquid inlet interface of the intelligent drinking device 102 is connected to a guide tube 104 for extending the liquid inlet, and the liquid outlet interface of the intelligent drinking device 102 is connected to a suction tube 101 for generating negative pressure.

[0099] The straw, composed of the guide tube 104 and the suction tube 101, has a tubular structure and is made of food-grade polypropylene. It forms a long, straight channel that guides fluid into the user's mouth. Its diameter is suitable for everyday drinking scenarios, and its length can be set according to usage requirements. The suction tube 101 connects to the liquid outlet interface 606 of the intelligent drinking device 102 via an adapter 103, and the guide tube 104 connects to the liquid inlet interface 607 of the intelligent drinking device 102 via an adapter 103, forming a complete fluid flow path. The intelligent beverage drinking device 100 can also be replaced with other drinking carrier forms such as a spout or a small drinking tube. The intelligent drinking device 102 can be interchangeably assembled with different drinking carrier forms.

[0100] Example 4: This embodiment provides another component for detecting the intake of target components during beverage consumption. Based on the same inventive concept, the target component intake detection component in this embodiment has the same structure as the target component intake detection component in Embodiment 1 above. The difference is that the flow detection component in this embodiment uses an ultrasonic flow meter, and the structure is redesigned to achieve miniaturization of the entire device. Specific embodiments will be described below.

[0101] like Figure 15 and Figure 16As shown, the detection component for detecting the intake of target components during beverage consumption provided in this embodiment includes a fluid cavity 408 with an inlet and an outlet, a flow detection component 301 for detecting the flow rate of liquid flowing through the fluid cavity, and a concentration detection component 302 for detecting the concentration of target components in the liquid flowing through the fluid cavity.

[0102] In some embodiments, the target component intake detection component further includes a first liquid retention tank 404A communicating with the fluid cavity 408 for retaining liquid. The first liquid retention tank 404A accesses the detection window of the concentration detection component 302, such that the detection window of the concentration detection component 302 is in continuous contact with the liquid as the liquid flows through the fluid cavity 408. The first liquid retention tank 404A is in communication with the fluid cavity 408. The bottom of the first liquid retention tank 404A has a mounting hole, through which the detection window of the concentration detection component 302 contacts the liquid in the fluid cavity 408.

[0103] In some embodiments, the concentration detection component 302 includes: an optical cavity 501, a prism 503 installed in the optical cavity 501, and a CCD sensor 504 installed at the bottom of the optical cavity 501, wherein the prism 503 and the mounting hole form the detection window.

[0104] Specifically, the liquid flow rate detected by the flow detection component 301 and the concentration of the target component in the liquid detected by the concentration detection component 302 are used to calculate the intake of the target component.

[0105] In some embodiments, the optical cavity 501 of the concentration detection component 302 is mounted on the optical cavity mounting base 401A via multiple fasteners. Its detection window can directly contact the liquid in the fluid cavity 408 through the first liquid retention tank 404A, achieving a partially non-contact measurement. Simultaneously, with the integrated detachable straw structure, the detection window can indirectly contact the liquid for measurement through a specially designed integrated detachable straw 105. Combined with the non-contact characteristics of the ultrasonic flow sensor, this achieves completely non-contact detection of the target component intake.

[0106] In some embodiments, the target component intake detection component further includes: two transducer channels 402A disposed on the wall of the fluid cavity 408 and communicating with the fluid cavity 408, wherein the center lines of the two transducer channels 402A coincide and form an acute angle with the center line of the fluid cavity 408; The flow detection component 301 is an ultrasonic flow meter, comprising a transmitting ultrasonic transducer 302A and a receiving ultrasonic transducer 302B respectively disposed on two transducer-guided channels 402A. This allows the ultrasonic waves emitted by the transmitting ultrasonic transducer 302A to radially pass through the fluid cavity 408 and ultimately be received by the receiving ultrasonic transducer 302B. The flow rate is then calculated based on the difference in upward and downward speeds and the time-of-flight difference between the ultrasonic transducers.

[0107] Specifically, the ultrasonic flow meter also includes an ultrasonic sensor circuit board 301A disposed outside the fluid cavity 408, and an ultrasonic transducer 302A at the transmitting end and an ultrasonic transducer 302B at the receiving end are respectively disposed at the transducer cutoff baffles 406A on both sides of the fluid cavity 408. See Figure 17 .

[0108] In some embodiments, the first liquid retention tank 404A is a tapered tank that is wider on the outside and narrower on the inside.

[0109] In some embodiments, the fluid cavity 408 includes a fluid channel 303A with a circular cross-section, see [link to previous document]. Figure 17 Alternatively, the fluid cavity 408 may include a fluid channel 303A with a square or rectangular cross-section, see [reference needed]. Figure 18 and Figure 19 In this embodiment, the fluid channel of the fluid cavity 408 can adopt different shapes, but the principle of its detection component is the same, only the internal shape is changed.

[0110] In some embodiments, a seal is provided between the prism 503 and the mounting hole.

[0111] In some embodiments, the target component content is calculated using the formula m=ρ*V*k (that is, the target component intake of a single beverage consumption is calculated, so that the total intake of multiple consumptions can be obtained as the user's total intake); where m is the target component content (that is, the mass of the target component); ρ is the target component concentration (actually the real-time concentration of the target component in the beverage fluid consumed in a single consumption); V is the liquid volume (actually the liquid volume consumed in a single consumption), which is calculated based on the time difference of flight between the upstream and downstream of the liquid collected by the ultrasonic sensor circuit board. The method of calculating the liquid volume is existing technology and will not be elaborated here; k is a correction coefficient.

[0112] The calculation method for the target component in this embodiment is the same as that for the target component intake detection component in Embodiment 1 above, and will not be elaborated further here.

[0113] Example 5: This embodiment also provides another intelligent drinking device, which will be described below with reference to specific embodiments.

[0114] like Figure 20 As shown, the smart drinking device of this embodiment includes a first housing for encapsulation, and a target ingredient intake detection component 206 located at the center of the first housing, as described in Embodiment 4 above.

[0115] In this embodiment, the intelligent drinking device further includes a main control circuit board 207A located on one side of the target ingredient intake detection component 206; the main control circuit board 207A is provided with a chipset and a power interface; a first battery 206A for power supply is located on the other side of the target ingredient intake detection component 206 and is electrically connected to the power interface on the main control circuit board 207A; maximizing the use of the idle space inside the housing without increasing the overall size of the device.

[0116] In some embodiments, the target component intake detection component is provided with an inlet pipe interface 607 at the inlet and an outlet pipe interface 606 at the outlet.

[0117] Preferably, depending on the shape of the straw, the cross-section of the fluid channel in the fluid cavity varies, and correspondingly, the cross-section of the guide channel in the outlet and inlet interfaces also varies. For example, if the straw is entirely cylindrical, the fluid channel 303A in the fluid cavity 408 is cylindrical, and the guide channels in the inlet and outlet interfaces are also circular. Of course, if the portions of the straw located in the fluid cavity, inlet interface, and outlet interface adopt other shapes, such as square or rectangular structures, the fluid channel in the fluid cavity, the guide channel in the inlet interface, and the guide channel in the outlet interface are all square or rectangular. Specifically, please refer to the detailed description of the two types of straws (detachable straws or integrated detachable straws) in the following embodiments.

[0118] In some embodiments, the first housing is divided into a first sub-housing 201A and a second sub-housing 202A that can be assembled together; wherein the first sub-housing 201A covers the top of the target ingredient intake detection component 206, and the second sub-housing 202A covers the bottom of the target ingredient intake detection component 206; and the first housing is provided with a button assembly 208A, specifically, the button assembly 208A is disposed on the outer wall of the second sub-housing 202A, and is used for operations such as power on / off and mode switching. The button assembly 208A includes an indicator light (a light ring in this embodiment) disposed on the outer wall of the second sub-housing, which is used to indicate the device status (such as charging or Bluetooth pairing status).

[0119] In some embodiments, the smart drinking device further includes a second housing fitted inside the first housing, the second housing including a third sub-housing 203A and a fourth sub-housing 204A that can be assembled and are arranged opposite to each other; the fourth sub-housing 204A covers one side of the main control circuit board 207A.

[0120] In this embodiment, the main control circuit board 207 is the control and power supply hub of the entire device. It is fixed to one side of the target component intake detection component 206 and is precisely positioned and fixed to the housing through a positioning structure. The main control circuit board 207A integrates a control module chip, a storage chip, a power management chip, a Bluetooth communication chip, and a power interface. The first battery 206A is directly connected to the power interface of the main control circuit board 207A, maximizing the use of the internal space of the housing.

[0121] In some embodiments, the first housing is provided with a light-emitting element. The light-emitting element can adopt the structure of the light-emitting component in Embodiment 2 (which has the same function as the light-emitting component in Embodiment 2, used to remind the user of light intake). Of course, another structure can also be adopted. Specifically, the light-emitting element includes: an annular light ring 209A installed on the outer side wall of the second housing and located at the connection between the first sub-housing and the second sub-housing. The annular light ring 209A is composed of multiple RGB full-color LED beads evenly arranged in a circle. It has a simple structure, uniform light emission, and the user can clearly see the light prompt at any angle. The light-emitting element also includes an annular light guide column 210A arranged along the outer side wall of the second housing and located at the connection between the first sub-housing 201A and the second sub-housing 202A. The annular light ring 209A and the annular light guide column 210A are precisely aligned. The annular light guide column 210A is located outside the annular light ring 209A. From an external perspective, the annular light guide column is integrated with the first housing. Specifically, the annular light guide column 210A is made of transparent material, and its function is the same as the transparent window in Embodiment 2. In this embodiment, the light-emitting elements (ring light ring 209A and ring light guide column 210A serving as its external transparent window) can emit different colors of light and flashing modes to achieve graded visual alerts. See [link to documentation]. Figure 20 .

[0122] In this embodiment, the chipset calculates the target ingredient intake based on the liquid flow rate and target ingredient concentration detected by the target ingredient intake detection component 206, and compares it with a preset threshold. If the target ingredient intake is less than the first threshold, the ring light ring 209A is controlled to issue a first warning; if the target ingredient intake is greater than the first threshold but less than the second threshold, the ring light ring 209A is controlled to issue a second warning; if the target ingredient intake is greater than or equal to the second threshold but less than the third threshold, the ring light ring 209A is controlled to issue a third warning; and if the target ingredient intake is greater than or equal to the third threshold, the ring light ring 209A is controlled to issue a fourth warning.

[0123] The preset threshold is the upper limit of the target ingredient intake set by the user in advance. It can be set through external smart devices such as mobile APP and stored synchronously in the memory chip of the main control circuit board 207A through the wireless communication module, and can be called by the chipset in real time.

[0124] Example 6: Based on the target ingredient intake detection component of Embodiment 4 above, or the intelligent drinking device of Embodiment 5 above, the present invention also provides another intelligent beverage drinking device, which will be described below in conjunction with specific embodiments.

[0125] In this embodiment, the intelligent beverage drinking device includes the intelligent drinking device 102 described in Embodiment 5 above; the liquid inlet port 607 of the intelligent drinking device is connected to a guide pipe 104 for extending into the liquid chamber 408, and the liquid outlet port 606 of the intelligent drinking device is connected to a suction pipe 101 for generating negative pressure.

[0126] In this embodiment, two optional fluid chambers are provided to interface with straws of different shapes to adapt to different usage needs.

[0127] For example: see Figure 21 The straw is a detachable, split-type straw 106, which includes the guide tube 104 and the suction tube 101 as described in Embodiment 3 above. These components respectively mate with the inlet port 607 and the outlet port 606 on the fluid chamber 408. Preferably, if both the guide tube 104 and the suction tube 101 are circular, correspondingly, the inlet port 607 and the outlet port 606 are provided with circular guide channels as docking guide channels for the detachable, split-type straw (i.e., the guide tube and the suction tube). Furthermore, the inlet port 607 and the outlet port 606 are each provided with a straw guide port 405A to dock with the guide tube 104 and the suction tube 101, thereby allowing the guide tube 104 and the suction tube 101 to communicate with the fluid chamber 408. Of course, in this embodiment, since an ultrasonic flow meter is used, in order to achieve miniaturization and to facilitate communication with the inlet and outlet pipe interfaces, the fluid channel 303A in the fluid cavity 408 adopts a straight-through columnar fluid channel, see [link to relevant documentation]. Figure 17 .

[0128] For example, see Figure 22The straw is an integrated detachable straw 105 (detachable here means it can be removed from the smart drinking device). Specifically, it also includes the guide tube 104 and the suction tube 101 in the above embodiment 3. The difference is that a transparent tube segment 1011 and a first connecting tube segment 1012 (preferably made of transparent material) that can extend into the fluid cavity 408 are sequentially arranged between the suction tube 101 and the guide tube 104 and are connected (for example, by ultrasonic welding). When the integrated detachable straw 105 passes through the fluid cavity 408, the transparent tube segment 1011 is located inside the fluid cavity 408, so that the concentration detection component can detect the liquid in the fluid cavity through the transparent tube segment 1011.

[0129] Preferably, the dimensions of the guide channels in the fluid cavity 408, the outlet pipe interface, and the inlet pipe interface are all matched with the dimensions of the transparent pipe section 1011, and the dimensions of the transparent pipe section 1011 are greater than or equal to the dimensions of the guide pipe 104 and the suction pipe 101.

[0130] Furthermore, in order to ensure that the straw can stably fit with the fluid cavity and that the transparent tube segment 1011 is located inside the fluid cavity, the size of the first connecting tube segment 1012 gradually decreases from top to bottom. Correspondingly, the guide channel in the liquid inlet port 607 for guiding the straw also adopts a narrowing design that gradually decreases from top to bottom, so that the straw can be known to be installed in place without additional assistance.

[0131] In other embodiments, a second connecting section 1013 (which may be made of transparent material or not) is provided between the suction tube 101 and the aforementioned transparent tube section 1011. The size of the second connecting section 1013 gradually increases from top to bottom, that is, the narrowing direction of the second connecting section is opposite to the narrowing direction of the first connecting section 1012. Correspondingly, the guide channel for guiding the suction tube in the liquid outlet port 606 also adopts a design that gradually narrows from top to bottom, so that the suction tube can be known to be installed in place without additional assistance.

[0132] Preferably, the cross-sections (i.e., the cross-sections obtained by cutting a plane perpendicular to its axis) of the first connecting pipe section 1012, the transparent pipe section 1011, and the second connecting pipe section 1013 are all square or rectangular (of course, other shapes can also be used). Correspondingly, the guide channels in the liquid inlet and liquid outlet interfaces are set as square or rectangular as the integrated straw guide port 502A, and the fluid channel 303A in the fluid cavity 408 is also square or rectangular.

[0133] Specifically, when the guide tube 104 and the suction tube 101 are pre-connected to form an integrated detachable suction tube 105, and it is vertically inserted into the fluid chamber 408 from above the target component intake detection component, when the first connecting tube section 1012 reaches the narrowed guide channel 501A in the liquid inlet interface, it indicates that the suction tube has reached the designated position and achieved stable connection. See [link to documentation]. Figure 22 and Figure 23 .

[0134] In this embodiment, the integrated detachable straw 105 is shown in the disconnected state (e.g., Figure 22 As shown), this is only used for achieving an integrated structure through ultrasonic welding. All liquid is confined inside the integrated detachable pipette 105, and there is no liquid in the fluid cavity 408. At this time, there is also no liquid in the first liquid retention tank 404A. However, the integrated detachable pipette 105 adopts a special splicing design in the middle section, which is approximately the same length as the fluid channel 303A in the fluid cavity 408. This section has high light transmittance, and the side corresponding to the target component measurement window has an arc-shaped rectangular transition structure. Therefore, even if there is no liquid in the first liquid retention tank 404A, reliable detection of the target component concentration can still be achieved.

[0135] Regardless of the form used, the ultrasonic sensor, concentration detection component, and straw assembly support completely non-contact or partially non-contact measurement, significantly improving user cleaning efficiency. Furthermore, since there are no moving parts inside the components, the risk of straw clogging or jamming is greatly reduced.

[0136] Specifically, both the detachable straw 106 and the integrated detachable straw 105 are tubular structures made of food-contact grade polypropylene, forming a long, direct-flow channel that guides fluid into the user's mouth. The diameter of the straw is suitable for everyday drinking scenarios, and the length can be set according to usage needs. The intelligent beverage drinking device can also be replaced with other drinking media such as a spout or a small drinking tube, allowing for interchangeable assembly between different drinking media forms.

[0137] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0138] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims. All of these forms are within the protection scope of the present invention.
