Abstract
Description
Technical Field
[0001] This invention relates to the field of intelligent drinking water appliances, and in particular to a water consumption monitoring system and a thermos cup that supports user identification. Background Technology
[0002] This user-identifiable hydration monitoring system and insulated water bottle is a smart water bottle that integrates identity authentication, hydration recording, water temperature display, and a safety lock. It uses technologies such as fingerprint recognition to verify user identity, automatically records a specific user's daily hydration, and synchronizes the data to a mobile device. This helps users, especially those with precise hydration management needs (such as patients and athletes), develop healthy drinking habits. Simultaneously, its locking function effectively prevents unauthorized use, ensuring personal hygiene.
[0003] However, existing user-identifiable hydration monitoring systems and insulated cups still have some structural design shortcomings. Firstly, for insulated cups with double-layered lids (such as flip-top lids), existing locking mechanisms typically only target the outermost second lid (the spout lid). The first lid underneath (the sealing lid) can often be opened directly by rotating it even when the second lid is locked. This renders the locking function ineffective, allowing others to easily access the liquid inside, failing to truly prevent unauthorized use and ensure personal hygiene. Secondly, these smart cups require battery power, which inevitably needs replacement after prolonged use. However, the battery compartment opening mechanism of existing insulated cups is often independent of the user identification system, allowing for direct opening and battery replacement without fingerprint unlocking. This not only reduces overall product security but may also facilitate malicious damage to the circuitry or batteries.
[0004] Therefore, it is necessary to provide a new water consumption monitoring system and thermos cup that supports user identification to solve the above-mentioned technical problems. Summary of the Invention

[0015] A water consumption monitoring system includes a thermos cup that supports user identification as described in any one of claims 1-9 and a weight pressure sensor. The weight pressure sensor is disposed inside the bottom of the cup body and is connected to a control circuit board via Bluetooth.
[0016] Compared with related technologies, the water consumption monitoring system and thermos cup that support user identification provided by the present invention have the following beneficial effects: I. Multiple linkage and locking mechanisms ensure thorough security. Effectively prevents unauthorized use: This invention completely solves the security loophole in the prior art where "the first lid can be unscrewed while the second lid is locked" through the dual protection of "spout locking (electronic locking component)" and "lid locking (mechanical limiting component)". Only after the user's fingerprint verification is successful will the system unlock the second lid first, and its opening action will then release the rotation restriction on the first lid. This progressive unlocking logic ensures that unauthorized personnel cannot drink directly from the cup or open the main lid to access the liquid inside, greatly improving the level of personal hygiene and safety.
[0017] Controllable Battery Compartment Access: Through the design of a "linked quick-change component," the opening of the battery compartment cover (expanding plate) is forcibly linked to the status of the second cover. The battery compartment cover can only be operated after the second cover has been opened with authorization. This effectively prevents anyone from arbitrarily opening the battery compartment, replacing batteries, or potentially interfering with the internal circuitry without authentication, ensuring the stability of the device's power supply and the integrity of its overall functionality, and integrating safety principles into every aspect of product use.
[0018] II. Simple and intelligent operation, excellent user experience One-touch automatic lid opening: Users only need to perform fingerprint recognition once. After successful verification, the control circuit board automatically drives the motor to retract the latch, and then the torsion spring will instantly pop open the second lid. The entire opening process is smooth and effortless, requiring no manual prying, providing a highly technological and convenient user experience.
[0019] Clear status indicators: It has an integrated display screen that can show information such as water temperature, current water consumption, and cumulative water consumption in real time, so that users can have a clear understanding of their own drinking status and effectively help to develop healthy drinking habits.
[0020] Easy maintenance and replacement: When the battery needs to be replaced, after unlocking the cover, users can simply use the lever to push the square column to open the unfolding plate. The operation is simple and intuitive. The specially designed groove on the control box also makes it convenient to remove the battery by hand.
[0021] III. Accurate water intake monitoring and efficient health management The integrated water intake monitoring system of this invention has a scientifically sound and reliable workflow. By using a high-precision weight and pressure sensor to monitor liquid level changes in real time, and combining this with algorithm processing on the control circuit board, it can accurately calculate the amount of water consumed each time. Compared to traditional methods that rely on user memory or manual recording, this automated monitoring method based on actual water intake data is more objective and accurate. It provides reliable data support for users who need to strictly control their daily water intake (such as patients with kidney disease, cardiovascular disease, or athletes), making health management more scientific and efficient.

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the invention and are not intended to limit the invention.
[0025] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.
[0026] like Figures 1 to 11As shown, a user-identifiable thermos cup includes: a cup body 1, a first lid 2 threadedly connected to the top of the cup body 1, and a second lid 3 on the top of the first lid 2; a first rotating block 4 fixedly connected to one end of the second lid 3, and a second rotating block 5 fixedly connected to the top of the second lid 3, the first rotating block 4 and the second rotating block 5 being rotatably connected via a first rotating shaft 6; a control box 7 fixedly connected to the side of the first lid 2 away from the first rotating block 4, and a display screen 8 fixedly connected to the side of the control box 7 away from the first lid 2, with one side of the control box 7 located on the display screen 8. A fingerprint reader 9 is fixedly connected to the bottom of the control box 7. A control circuit board 10 and a battery 35 are installed inside the control box 7. A temperature sensor 11 is fixedly connected inside the first cup lid 2. The display screen 8, fingerprint reader 9, and temperature sensor 11 are all electrically connected to the control circuit board 10. A locking component is installed inside the first cup lid 2 to restrict the opening of the second cup lid 3. A limit component is installed on the side of the first cup lid 2 near the first rotating block 4 to limit the rotation of the first cup lid 2. A quick-change component is installed on one side of the control box 7 for quickly replacing the battery 35. Torsion springs 31 are symmetrically fixedly connected inside the second rotating block 5. The opposing ends of the two torsion springs 31 are fixedly connected to the first rotating block 4. The torsion springs 31 always apply a torque to the first rotating block 4 to open the second cup lid 3. A groove 32 is provided on both sides of the battery 35 at one end of the control box 7 to facilitate the removal of the battery 35 by hand. A straw 33 is inserted through the middle of the first cup lid 2.
[0027] This part forms the core architecture and information perception foundation of the entire system. The cup body 1 and the first lid 2 constitute the main water storage container, while the second lid 3 serves as the drinking spout. After the user verifies their identity via the fingerprint reader 9, the control circuit board 10 controls the locking component to unlock the second lid 3. At this time, under the pre-tightening torque of the torsion spring 31, the first rotating block 4 rotates around the first rotating shaft 6, thereby automatically opening the second lid 3 for the user's convenience in drinking. The straw 33 allows the user to directly siphon the liquid from the cup. A groove 32 at one end of the control box 7 provides a point of leverage for the user to pry out the battery 35 with their fingernail or a tool after authorization. The entire system is powered by the battery 35, and the various electronic components work together through electrical connection with the control circuit board 10 to achieve comprehensive monitoring and management of drinking volume, user identity, and cup lid status. The control box 7 also has a voiceprint recognition module inside. The voiceprint recognition module records the user's voice characteristics, and the user can unlock the device by saying preset content.
[0028] like Figures 3 to 7As shown, the locking assembly includes: a locking block 12; a first groove 13 is provided on the top of the control box 7; the locking block 12 is slidably disposed in the first groove 13; a slot 14 is provided on the side of the first cup lid 2 away from the first rotating block 4; the locking block 12 is engaged with the slot 14; a first spring 15 is provided inside the first groove 13; one end of the first spring 15 is fixedly connected to the locking block 12; the other end of the first spring 15 is fixedly connected to the inner wall of the control box 7; the first spring 15 is a compression spring; the first spring 15 always pushes the locking block 12 closer to the second cup lid 3. The control box 7 has a second slide groove 16 inside, and a connecting rod 17 is slidably connected inside the second slide groove 16. The connecting rod 17 has a Z-shaped design. The top of the connecting rod 17 is fixedly connected to the bottom of the locking block 12. The control box 7 has a second rotating shaft 18 rotatably connected inside, and a lever 19 is symmetrically fixedly connected to the outer wall of the second rotating shaft 18. The lever 19 contacts the bottom side wall of the connecting rod 17. The control box 7 has a motor 20 fixedly connected inside, and the output end of the motor 20 is fixedly connected to the second rotating shaft 18. The motor 20 is electrically connected to the fingerprint reader 9 through the control circuit board 10. When the fingerprint recognition is successful, the motor 20 will drive the second rotating shaft 18 to rotate 180°. The second cup lid 3 will open with the rotation of the first rotating block 4 under the action of the torsion spring 31.
[0029] This component is the core actuator that enables the lid to open automatically after user identification.
[0030] Locked State: When no fingerprint is recognized, the motor 20 is not working. At this time, the second cup lid 3 is in the closed state, the first spring 15 is in the compressed state, and its elastic force continuously pushes the locking block 12 to slide towards the second cup lid 3 within the first slide groove 13, so that the locking block 12 is firmly inserted into the locking groove 14 of the second cup lid 3. At this time, even if the torsion spring 31 has a tendency to pop open the second cup lid 3, the second cup lid 3 is mechanically locked and cannot be opened.
[0031] Unlocking Process: When the user successfully verifies their identity on the fingerprint reader 9, the control circuit board 10 sends a command to the motor 20. The motor 20 starts, driving the second rotating shaft 18 and the toggle plate 19 fixed thereon to rotate. The rotating toggle plate 19 presses against the side wall at the bottom of the connecting rod 17. Since the connecting rod 17 has a Z-shaped design and is restricted to sliding within the second slide groove 16, the pressing action of the toggle plate 19 drives the entire connecting rod 17 to move downwards. The connecting rod 17 drives the locking block 12 fixed thereto to overcome the elastic force of the first spring 15 and disengage from the slot 14 of the second cup lid 3. Once the locking block 12 disengages from the slot 14, the second cup lid 3 immediately and automatically pops open under the action of the torsion spring 31, completing the unlocking process.
[0032] like Figures 8 to 10As shown, the limiting assembly includes: a limiting rod 21, which is slidably disposed on the side of the first cup lid 2 near the first rotating block 4, and the length of the limiting rod 21 is greater than the axial length of the first cup lid 2; a limiting groove 22 is formed on the top of the cup body 1, and when the second cup lid 3 is closed, the bottom end of the limiting rod 21 is inserted into the limiting groove 22, and the top end of the limiting rod 21 is pressed into contact with the second cup lid 3. Slider blocks 23 are fixedly connected to both sides of the limiting rod 21. A third sliding groove 24 is symmetrically formed inside the first cup lid 2, and the height of the third sliding groove 24 is three times the height of the slider 23. The slider 23 slides within the third sliding groove 24. A second spring 25 is provided within the third sliding groove 24, and the top end of the second spring 25 is fixedly connected to the slider 23, and the bottom end of the second spring 25 is fixedly connected to the inner wall of the first cup lid 2. The second spring 25 is a compression spring, and the second spring 25 always applies an upward force to the slider 23.
[0033] This component is a key mechanical safeguard to prevent the first cup lid 2 from being twisted open arbitrarily.
[0034] Locked State (Second Lid 3 Closed): When the second lid 3 is closed, its inner wall presses downward against the top of the limiting rod 21. Under this pressure, the limiting rod 21 moves downward, causing the sliders 23 on both sides to slide downward within the third groove 24, compressing the second spring 25. The bottom end of the limiting rod 21 then inserts downward into the limiting groove 22 at the top of the cup body 1. At this point, because the limiting rod 21 passes through both the first lid 2 and the cup body 1, a mechanical interlock is formed, preventing the first lid 2 from rotating relative to the cup body 1 and thus preventing it from being unscrewed.
[0035] Unlocked State (Second Lid 3 Open): When the second lid 3 is authorized to open, the pressure on the top of the limiting rod 21 disappears. At this time, the compressed second spring 25 releases its elasticity, pushing the slider 23 and the limiting rod 21 upwards as a whole, so that the bottom end of the limiting rod 21 completely exits the limiting groove 22 of the cup body 1. The rotation restriction on the first lid 2 is released, and the first lid 2 can now be rotated and unscrewed normally for adding water or cleaning.
[0036] like Figure 4 and Figure 5As shown, the quick-change assembly includes: an unfolding plate 26, which is rotatably mounted on one side of the control box 7. A fourth sliding groove 27 is formed on the top of the unfolding plate 26. The fourth sliding groove 27 has a square longitudinal section. A square post 28 is slidably connected inside the fourth sliding groove 27. A semi-square groove 29 is formed on the opposite side of the first cup lid 2 and the second cup lid 3. The height of both semi-square grooves 29 is half the height of the square post 28. The square post 28 is inserted into the semi-square groove 29. A third spring 34 is provided inside the fourth sliding groove 27. One end of the third spring 34 is fixedly connected to the square post 28, and the other end of the second spring 25 is fixedly connected to the inner wall of the unfolding plate 26. The third spring 34 is a compression spring, which constantly applies a force to the square post 28, causing the square post 28 to move closer to the first cup lid 2. A lever 30 is rotatably connected to the side of the square post 28 closest to the first cup lid 2.
[0037] This component enables the battery compartment cover and cup lid to lock together, ensuring safety.
[0038] Locked State: When the second cup lid 3 is closed, the unfolding plate 26 (i.e., the battery compartment cover 35) is in the closed state. At this time, the square post 28 is located at the bottom of the fourth slide groove 27 under the action of gravity or a slight external force. The semi-square grooves 29 on the first cup lid 2 and the second cup lid 3 are exactly aligned, forming a complete square hole. The square post 28 is inserted into this aligned semi-square groove 29. Under the restriction of the square hole, the square post 28 cannot rotate, and therefore the unfolding plate 26 cannot be directly opened.
[0039] Unlocking and Replacement: Only when the user verifies their fingerprint and the second cup lid 3 is opened, does the semi-square groove 29 on the second cup lid 3 move away, releasing the lateral constraint on the square post 28. At this time, the user pushes the square post 28 with the lever 30 and compresses the third spring 34, causing it to fully enter the fourth sliding groove 27. The square post 28 then breaks free from the restriction of the semi-square groove 29, allowing the unfolding plate 26 to rotate freely and open, thus exposing the battery 35 compartment for battery replacement. This ensures that the battery 35 can only be replaced when the cup lid is unlocked.
[0040] A water consumption monitoring system, characterized in that it includes a thermos cup that supports user identification as described in any one of claims 1-9 and a weight pressure sensor 36, wherein the weight pressure sensor 36 is disposed inside the bottom end of the cup body 1 and is electrically connected to the control circuit board 10.
[0041] During the drinking process, the weight pressure sensor 36 monitors the change in liquid level in the cup in real time by measuring the weight change of the water inside, while the temperature sensor 11 monitors the water temperature in real time. This data is sent to the control circuit board 10, and after processing and analysis, the system can calculate the amount of water drunk in a single session and the cumulative amount of water drunk, and feed back the water volume data, real-time water temperature and other information to the user through the display screen 8.
[0042] The working principle of this invention is as follows: In standby mode, the thermos is fully locked. The motor 20 in the electronic locking assembly is not activated, and the latch 12, pushed by the first spring 15, inserts into the latch 14 of the second lid 3, firmly locking the spout. Simultaneously, since the second lid 3 is closed, it presses down on the limiting rod 21 of the mechanical limiting assembly, causing its bottom end to insert into the limiting groove 22 of the cup body 1, preventing the first lid 2 from rotating open. Furthermore, the square post 28 of the quick-change assembly falls into the square hole formed by the semi-square groove 29 aligned with the first lid 2 and the second lid 3, locking the unfolding plate 26 of the battery compartment 35 to the lid structure as well. This triple mechanical interlocking constitutes a highly secure protection system, effectively preventing unauthorized use and unauthorized opening of the battery compartment 35.
[0043] When an authorized user needs to use the water cup, the process begins with identity authentication. The user places their finger on the fingerprint reader 9, which sends the collected information to the control circuit board 10 for verification. Once verification is successful, the control circuit board 10 immediately activates the motor 20 of the electronic locking assembly. The motor 20 drives the second rotating shaft 18 and the toggle plate 19 to rotate. The toggle plate 19 presses down on the connecting rod 17, forcing the locking block 12 to overcome the elastic force of the first spring 15 and disengage from the slot 14 of the second cup lid 3. Once the locking block 12 is unlocked, the pre-tensioned torsion spring 31 immediately releases its torque, automatically opening the second cup lid 3, allowing the user to drink water through the straw 33.
[0044] Opening the second lid 3 simultaneously triggered the unlocking of two other components: When the pressure on the limiting rod 21 disappears, the second spring 25 pushes the limiting rod 21 to rise, causing its bottom end to exit from the limiting groove 22 of the cup body 1, thus releasing the rotation restriction on the first cup lid 2. At this time, the user can unscrew the first cup lid 2 to add water.
[0045] It moves the half-square groove 29 on it away, breaking the complete square hole formed with the half-square groove 29 on the first cup lid 2. At this time, the user can use the lever 30 to push the square post 28 into the depth of the fourth slide groove 27, which will allow the unfolding plate 26 to be rotated and opened, removing the protection of the battery 35. Then, the user can use their fingers to touch the battery 35 through the groove 32 on the control box 7 to replace the battery 35.
[0046] Throughout the entire process, the weight pressure sensor 36 and temperature sensor 11 continuously operate, feeding back liquid level and temperature data to the control circuit board 10. The system monitors drinking water volume by calculating water level changes and displays information such as water volume and temperature on the display screen 8 in real time, helping users scientifically manage their drinking water health.
[0047] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
