Description

Technical Field

[0001] This invention relates to the field of vibration spectral composite sensing liquid poison alarm system and intelligent drinking container. Background Technology

[0002] With the increasing prevalence of smart homes and wearable devices, consumers' demand for safe drinking water is growing daily. Traditional liquid monitoring solutions mainly suffer from the following technical shortcomings: The monitoring methods are limited and the anti-interference ability is poor: Most existing smart water cups are only equipped with basic physicochemical sensors (such as TDS pens or simple pH meters), which cannot perform qualitative analysis on complex chemically synthesized toxins. High-precision spectral or electrochemical sensors are highly sensitive to ambient temperature, pH, and suspended particles, and are prone to baseline drift in complex drinking scenarios, resulting in a very high false alarm rate.

[0003] The trade-off between sensor power consumption management and response efficiency: In pursuit of detection accuracy, continuously operating high-performance sensors leads to a surge in system power consumption, severely shortening battery life, and frequent operation accelerates the physical wear and tear of the sensor components. Currently, there is a lack of a management mechanism capable of dynamically scheduling sensors based on liquid safety levels.

[0004] Lack of active physical blocking mechanisms: Existing water quality alarm systems mostly adopt a "passive prompting" mode (i.e., only displaying alarm information in the APP or on the cup itself), which cannot implement forced blocking at the hardware level. When users accidentally operate the system in emergency situations (such as in unfamiliar environments), text prompts alone cannot effectively ensure drinking safety.

[0005] Insufficient environmental adaptability: Drinking liquids have complex compositions, often containing additives such as tea and coffee in addition to water. Existing technologies lack effective user operation learning capabilities and environmental benchmark calibration capabilities, resulting in "false alarms" becoming a key pain point affecting user experience. Summary of the Invention

[0007] In a first aspect of the present invention, a vibration spectral composite sensing liquid poison alarm system and an intelligent drinking container are provided.

[0008] This vibration spectrum composite sensing liquid poison alarm system includes an electronic circuit board, four monitoring components, a timing scheduling module, a data acquisition module, a cross-validation and comprehensive evaluation module, a graded early warning control module, a communication module, an audio-visual interaction module, and an electromagnetic lock control module.

The timing scheduling module is used to activate the four monitoring components sequentially according to a preset tiered timing sequence; The data acquisition module is used to read the liquid parameters collected by the monitoring component when it is in an active state; The cross-validation and comprehensive evaluation module is used to extract the liquid parameters output by the pre-activated monitoring component as environmental variables, and call the environmental variables to perform dynamic drift calibration and baseline smoothing on the detection data output by the subsequently activated monitoring component, and output a comprehensive risk rating based on the comparison results. The graded early warning control module is used to implement differentiated electromagnetic locking and early warning interaction strategies based on the comprehensive risk rating.

[0009] Preferably, the four monitoring components are respectively configured as a first monitoring component, a second monitoring component, a third monitoring component, and a fourth monitoring component; The first monitoring component is configured as a vibration spectral sensing unit, used to emit excitation light and receive Raman or infrared spectral feature sequences of liquid molecules; The second monitoring component is configured as an electrochemical sensing unit, used to apply a scanning voltage to the water body and acquire the redox current curve of heavy metal ions; The third monitoring component is configured as a physical property sensing unit, used to acquire the total dissolved solids and turbidity parameters of the liquid; The fourth monitoring component is configured as a physicochemical environment sensing unit, used to acquire the real-time temperature and pH of the liquid.

[0010] Preferably, the specific execution process of the timing scheduling module activating the four monitoring components sequentially according to the stepped timing sequence includes: First, activate the fourth monitoring component and the third monitoring component; The second monitoring component is then activated; Finally, the first monitoring component is activated.

[0011] Preferably, the specific execution process of dynamic drift calibration and baseline smoothing by the cross-validation and comprehensive evaluation module includes: The temperature and pH value collected by the fourth monitoring component are used as environmental variables. A preset compensation algorithm is used to perform drift calibration on the redox peak potential obtained by the second monitoring component, and the corrected heavy metal ion concentration is output. The turbidity parameter obtained by the third monitoring component is introduced, and dynamic fluorescence background subtraction and baseline smoothing are performed on the original spectral sequence obtained by the first monitoring component. The spectral feature peaks are extracted and compared with the local database to output the comprehensive risk rating.

[0012] Preferably, it also includes a user interaction takeover module, which is integrated into the core processing chip of the electronic circuit board; the differentiated strategies implemented by the hierarchical early warning control module based on the comprehensive risk rating include mutually independent level one early warning, level two early warning and level three early warning.

[0013] Preferably, when the cross-validation and comprehensive evaluation module determines that the water sample does not contain harmful chemical components or excessive heavy metals, but the basic physicochemical parameters deviate from the optimal drinking range, the first-level warning is triggered. In the first-level warning state, the hierarchical warning control module controls the electromagnetic lock control module to issue an unlocking command to release the physical lock, and at the same time controls the audio-visual interaction module to issue a regular safety prompt.

[0014] Preferably, the secondary warning is triggered when an unknown feature peak is extracted from the spectral feature sequence and no deadly toxic substance matrix is ​​matched; In the level 2 warning state, the graded warning control module controls the electromagnetic lock control module to remain locked, the communication module pushes an authorization request to an external smart terminal, and the user interaction takeover module intervenes. If the user interaction takeover module receives a security authorization command, it marks the spectral feature sequence as a security whitelist and controls the electromagnetic lock control module to unlock; if no authorization command is received, the electromagnetic lock control module remains locked.

[0015] Preferably, the three-level warning is triggered when the cross-validation and comprehensive evaluation module matches the spectral characteristics of a highly toxic substance, or detects excessive levels of strong acid, strong alkali, or heavy metals. In the three-level warning state, the graded warning control module controls the electromagnetic lock control module to enter a high-power continuous locking state to cut off the hardware unlocking circuit, and the sound and light interaction module triggers a strobe and buzzer alarm; in this state, the user interaction takeover module is forcibly suspended and refuses to accept any authorized unlocking command.

[0016] In a second aspect of the invention, a smart drinking container is provided.

[0017] Includes container components, connection components, and switching components; The container assembly includes a lid, a cup body, and a cavity disposed inside the cup body, wherein the lid is screwed onto the top opening of the cup body; The switching assembly is located at the bottom of the cup body and includes a top plate, a rotating plate, and four monitoring components. The top plate is fixedly mounted on the bottom inner wall of the cavity, and the rotating plate is rotatably mounted below the top plate. The top plate and the rotating plate are tightly fitted together to form a physical water seal within the cup body. A detection groove is provided on the rotating plate, and the four monitoring components are installed inside the detection groove. A hole is provided on the top plate that mates with the detection groove. The connecting component includes an electromagnet and a magnetic attractor, which are respectively disposed on the outer side of the top of the cup body and the inner side of the lid body. The electromagnet is electrically connected to the electromagnetic lock control module of the alarm system. The rotating plate is connected to the cover body via a transmission. When the cover body is loosened to a preset position, the screwing displacement of the cover body drives the rotating plate to rotate, so that the hole body is precisely aligned with the detection groove, allowing the liquid in the cavity to flow into the detection groove for parallel monitoring. At the same time, the alarm system triggers the electromagnet to be energized and attract the magnetic suction component, locking the cover body in the preset position.

[0018] Preferably, when the cover is tightened normally, the holes in the top plate and the detection grooves in the rotating plate are in a staggered and closed state, so that the four monitoring components are physically isolated from the liquid in the cavity; When the alarm system determines that the water quality is safe and controls the electromagnet to be de-energized and unlocked, the detection tank and the orifice remain in communication during the removal of the cover and drinking process, so that the residual water sample inside the detection tank can flow back into the cavity through the orifice by gravity when the cup is tilted or inverted.

[0019] One or more technical solutions provided in this application have at least the following technical effects or advantages: The vibration spectral composite sensing liquid poison alarm system and intelligent drinking container provided by this invention, through the collaboration of a "cross-validation and comprehensive evaluation module" and a "time-sequence scheduling module," utilizes physicochemical environmental data (temperature, pH, turbidity) as a benchmark to dynamically compensate and smooth the highly sensitive vibration spectral and electrochemical signals. This mechanism effectively eliminates signal drift caused by environmental fluctuations, significantly improving detection accuracy and stability in complex liquid environments.

Detailed Implementation

[0023] 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 embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Furthermore, the term "and / or" in this article only describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects are in an "or" relationship.

[0025] like Figure 1 As shown, one embodiment of the present invention provides a vibration spectrum composite sensing liquid poison alarm system, including an electronic circuit board, four monitoring components 54, a timing scheduling module, a data acquisition module, a cross-validation and comprehensive evaluation module, a graded early warning control module, a user interaction takeover module, a communication module, an audio-visual interaction module, and an electromagnetic lock control module; The electronic circuit board is located in the sealed space at the bottom of the cup body 13. The timing scheduling module, data acquisition module, cross-validation and comprehensive evaluation module, hierarchical early warning control module and user interaction takeover module are all integrated into the core processing chip of the electronic circuit board; the four monitoring components 54 are electrically connected to the data acquisition module; the hierarchical early warning control module is electrically connected to the sound and light interaction module, the electromagnetic lock control module and the communication module respectively. The four monitoring components 54 are configured as different parameter acquisition units, and their specific monitoring principles and configurations are as follows: The first monitoring component is configured as a vibration spectral sensing unit. Its monitoring principle is to use a micro laser source to emit excitation light of a specific wavelength into the water sample in the detection tank 531. When the excitation light irradiates the toxic organic molecules, the stretching and bending vibrations of the chemical bonds inside the molecules will absorb and scatter photons, generating Raman scattering spectra or infrared absorption spectra with specific frequency shifts. This spectral sequence serves as an "optical fingerprint" reflecting the internal structure of the molecules, which can accurately characterize complex chemically synthesized toxins. The second monitoring component is configured as an electrochemical sensing unit. Its monitoring principle is to use screen-printed microelectrodes. The array applies a specific scanning voltage to the water body. Different heavy metal ions undergo redox reactions at specific potentials and generate corresponding Faraday currents. By capturing the current peak and its corresponding potential, quantitative analysis of the concentration of toxic heavy metal ions such as lead, cadmium, and mercury can be achieved. The third monitoring component is configured as a physical property sensing unit, which uses a photosensitive receiver to capture the light scattering intensity caused by suspended particles to obtain turbidity values, and uses microelectrodes to measure the conductivity of the liquid to calculate the total dissolved solids value. The fourth monitoring component is configured as a physicochemical environment sensing unit, which uses the selective response of a glass electrode to hydrogen ions to obtain pH, and uses the resistance change of a thermistor to obtain the real-time temperature of the liquid.

[0026] In practical use, after the timing scheduling module triggers the detection action, the four monitoring components 54 are activated sequentially according to a stepped timing control, and their synergistic effects are achieved: First, the fourth and third monitoring components are activated, and the data acquisition module quickly reads parameters such as temperature, pH, turbidity, and total dissolved solids. The cross-validation and comprehensive evaluation module performs preliminary logical judgment; if the parameters are within the analyzable range, the current temperature and pH are extracted as environmental variables. This preliminary rapid screening not only instantly eliminates extreme strong acids and alkalis but also avoids the ineffective activation of high-power components, reducing the overall energy consumption of the system. Subsequently, the timing scheduling module activates the second monitoring component to obtain the electrochemical current curve, and the cross-validation and comprehensive evaluation module calls the environmental variables and uses a preset compensation algorithm to perform dynamic drift calibration of the redox peak potential of heavy metals based on temperature and pH, outputting the corrected heavy metal ion concentration. This calibration process overcomes the technical bias of electrochemical sensor distortion caused by pouring hot or cold water into conventional drinking containers, greatly improving the accuracy of heavy metal detection. Finally, the first monitoring component is activated to emit excitation light and receive spectral feature sequences. The cross-validation and comprehensive evaluation module introduces turbidity parameters to perform dynamic fluorescence background subtraction and baseline smoothing on the original spectral sequences, eliminating scattering interference from turbid particles in the water on optical detection. Subsequently, the pure spectral feature peaks are extracted and compared with the local database to output a comprehensive risk rating. This multi-source data cross-fusion process, which proceeds from macroscopic physicochemical analysis to microscopic qualitative analysis, completely solves the technical problem that a single sensor is prone to causing false alarms.

[0027] The tiered early warning control module implements differentiated linkage strategies and user permission allocation based on a comprehensive risk rating. When the cross-validation and comprehensive evaluation module determines that the water sample does not contain harmful chemical components or excessive heavy metals, but the basic physicochemical parameters deviate from the optimal drinking range (e.g., water temperature is too high or total dissolved solids are slightly high), a level one early warning is triggered. The tiered early warning control module controls the electromagnetic lock control module to issue an unlocking command, de-energizing the electromagnet 21 and releasing the physical lock of the cover 11. At the same time, it controls the audio-visual interaction module to issue a routine safety prompt. After receiving the information, the user can decide whether to open the cover 11 to drink based on their own habits, avoiding excessive intervention of the safety system in daily drinking behavior.

[0028] When dense unknown feature peaks are extracted from the spectral feature sequence, accompanied by a significant increase in turbidity and total dissolved solids, and no deadly toxic substance matrix is ​​matched, a secondary warning is triggered. This state typically occurs when a user is legally brewing tea, coffee, or functional beverages. The graded warning control module controls the electromagnetic lock control module to keep electromagnet 21 locked, implementing primary defense to prevent accidental ingestion of unknown liquids. Simultaneously, the audio-visual interaction module issues a warning and inquires about the cause of the liquid composition change, and the communication module pushes an authorization request to the smart terminal. At this point, the user interaction takeover module intervenes. If it receives a security authorization command from the user via a button on the interactive screen component 12 or a smart terminal, the system marks the unknown spectral feature sequence as a user-specific security whitelist and controls the electromagnetic lock control module to de-energize and unlock electromagnet 21. If no authorization command is received, the electromagnetic lock control module remains locked. This design cleverly balances poison prevention safety with ease of use when brewing beverages, giving the system adaptive learning capabilities.

[0029] Furthermore, when the cross-validation and comprehensive evaluation module clearly matches the spectral characteristics of highly toxic substances, or detects severe exceedances of strong acids, strong alkalis, and heavy metals, a level-three warning is triggered. The graded warning control module controls the electromagnetic lock control module to put the electromagnet 21 into a high-power continuous energized locking state, completely cutting off the hardware unlocking circuit from the physical level. The sound and light interaction module triggers a high-frequency strobe and buzzer alarm, and the communication module silently sends an emergency help signal in the background. In this state, the user interaction takeover module is forcibly suspended, refusing to accept any external authorized unlocking commands, thereby forcibly preventing the user from accidentally drinking the contents of the cap 11 by an irreversible physical deadlock state, constructing the last line of defense to protect life safety.

[0030] like Figures 2 to 9 As shown, another embodiment of the present invention also provides an intelligent drinking container, which integrates a mechanical linkage sampling and controlled locking mechanism, and mainly includes a container component 1, a connecting component 2, a linkage component 4, a switching component 5, and a draining component 6.

[0031] The container assembly 1 includes a lid 11, an interactive screen assembly 12, a cup body 13, a cavity 14 disposed inside the cup body 13 for containing liquid, and a protrusion 15 disposed at the opening at the top of the cup body 13. The lid 11 has an internal thread 111 on its inner side, and the protrusion 15 has an external thread 151 on its outer side. The lid 11 is screwed onto the protrusion 15 via the internal thread 111 and the external thread 151, and the outer diameter of the protrusion 15 is slightly smaller than the outer diameter of the cup body 13. The interactive screen assembly 12 is embedded in the top of the lid 11. The connecting assembly 2 includes an electromagnet 21 and a magnetic attractor 22, which are respectively disposed on the outer side wall of the protrusion 15 and the inner side wall of the lid 11.

[0032] The linkage assembly 4 is used to convert the screwing displacement of the lid 11 into the opening and closing driving force of the bottom. The linkage assembly 4 includes a connecting plate 41, a limiting rod 42, a spring 43, a connecting rod 44, a rotating cylinder 45, and an inclined groove 46 formed on the outer wall of the rotating cylinder 45. A vertical sliding groove 131 communicating with the cavity 14 is formed on the inner side wall of the cup body 13. The connecting plate 41 is slidably disposed in the sliding groove 131, and the top end of the connecting plate 41 can contact the bottom end face of the lid body 11. A groove is formed at the bottom of the connecting plate 41 and is slidably sleeved on the limiting rod 42. The bottom end of the limiting rod 42 is fixed to the bottom surface of the sliding groove 131. The spring 43 is sleeved on the outside of the limiting rod 42, and its two ends abut against the bottom of the connecting plate 41 and the bottom surface of the sliding groove 131, respectively. A connecting rod 44 is fixedly connected to the lower side of the connecting plate 41, and the other end of the connecting rod 44 extends into and slides into the inclined groove 46 of the rotating cylinder 45. Through this mechanism, the linear lifting motion of the connecting rod 44 can be converted into the rotational motion of the rotating drum 45.

[0033] The switching assembly 5 is located at the bottom of the cup body 13 and is used to achieve controlled extraction and physical isolation of water samples. The switching assembly 5 includes a main shaft 51, a top plate 52, a rotating plate 53, and four monitoring components 54. The top end of the main shaft 51 is fixedly connected to the inner side of the rotating cylinder 45, and the bottom end is rotatably connected to the bottom of the inner wall of the cup body 13. The rotating plate 53 is fixedly sleeved on the main shaft 51 and is rotatably and sealingly connected to the inner wall of the cavity 14. Four detection slots 531 are evenly opened in the circumferential direction of the rotating plate 53, and the four monitoring components 54 are respectively sealed and installed inside the detection slots 531. The top plate 52 is fixedly set on the bottom inner wall of the cavity 14 and is tightly fitted to the top of the rotating plate 53. Four holes 521 are opened on the top plate 52, so that the holes 521 and the detection slots 531 can form a liquid phase seal when they are staggered.

[0034] It is worth noting that, in terms of spatial layout, the top plate 52 and the rotating plate 53 form a horizontal physical water seal partition inside the cup body 13. The space above this partition is a cavity 14 for containing drinking liquid, while all the linkage components 4, including the rotating cylinder 45, the inclined groove 46, and other transmission components, are hidden in the dry space below the rotating plate 53. This "water storage above, linkage below" isolation design ensures that the complex mechanical transmission mechanism will not be rusted or damaged by water immersion, and also avoids secondary pollution of drinking water by friction dust or lubricating materials from mechanical parts.

[0035] In actual use, when the user loosens the lid 11 to drink water, the lid 11 moves upward along the thread, releasing the downward pressure on the connecting plate 41. Under the elastic restoring force of the spring 43, the connecting plate 41 moves upward along the slide groove 131 to the highest point. The upward displacement of the connecting plate 41 drives the connecting rod 44 to slide along the inclined groove 46, thereby driving the rotating cylinder 45, the main shaft 51, and the rotating plate 53 to rotate at a specific angle. When the lid 11 rotates to the preset half-open position, the bottom end face of the lid 11 forms a gap 3 with the top of the cup body 13. At this time, the hole 521 on the top plate 52 is exactly aligned with the detection groove 531 on the rotating plate 53. The liquid in the cavity 14 flows into the four detection grooves 531 through the hole 521 and is monitored in parallel by the four monitoring components 54. At the same time, the connecting component 2 is triggered, the electromagnet 21 is energized and firmly attracts the magnetic suction piece 22, locking the lid 11 in the half-open position by magnetic force. During this testing process, the user cannot forcibly unscrew the cover 11, thus establishing a hardware security barrier for mandatory testing.

[0036] If the monitoring component 54 determines that the water quality is safe, the electromagnet 21 is de-energized, releasing the magnetic suction component 22, unlocking the lid 11, and allowing the user to continue rotating and remove the lid 11. When the user tilts or inverts the cup 13 to drink, since the orifice 521 and the detection groove 531 are still in communication, the residual water sample inside the detection groove 531 flows smoothly back into the cavity 14 under the action of gravity through the large-diameter orifice 521. After drinking, the user tightens the lid 11 again. During the final stroke of the closing motion, the lid 11 presses down on the connecting plate 41, causing it to move downward against the elastic force of the spring 43. The connecting rod 44 then drives the inclined groove 46 downward, causing the rotating plate 53 to rotate in the opposite direction and reset, so that the orifice 521 and the detection groove 531 are misaligned and closed again. This purely mechanical opening and closing logic effectively avoids the monitoring component 54 being immersed in liquid for a long time under normal conditions, extending the sensor's lifespan.

[0037] Furthermore, this embodiment can also employ a drainage assembly 6 for active waste liquid removal. The drainage assembly 6 includes a one-way valve 61, an annular shell 62, a drainage pipe 63, and a micro pump 64. The annular shell 62 is located below the rotating plate 53 and is connected in one direction to the bottom of the four detection tanks 531 via four one-way valves 61. The bottom outlet of the annular shell 62 is connected to the input end of the micro pump 64, and the output end of the micro pump 64 is connected to the drainage pipe 63. In actual use, when an abnormality is detected or residual liquid needs to be cleaned, the micro pump 64 starts to generate negative pressure, forcibly drawing the residual liquid inside the detection tank 531 into the annular shell 62 through the one-way valve 61. Subsequently, it is discharged into the independent water storage chamber at the bottom of the cup through the drainage pipe 63, or directly drained to the external environment, ensuring the purity of the sample for the next test.

[0038] The specific embodiments described above do not constitute a limitation on the scope of protection of this invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this invention should be included within the scope of protection of this invention.

A smart drinking container, used in conjunction with the vibration spectral composite sensing liquid poison alarm system as described in any one of claims 1 to 8, characterized in that, It includes a container component (1), a connection component (2), and a switching component (5); The container assembly (1) includes a lid (11), a cup (13) and a cavity (14) disposed inside the cup (13), wherein the lid (11) is screwed onto the top opening of the cup (13); The switching component (5) is located at the bottom of the cup body (13) and includes a top plate (52), a rotating plate (53), and four monitoring components (54). The top plate (52) is fixedly installed on the bottom inner wall of the cavity (14), and the rotating plate (53) is rotatably installed below the top plate (52). The top plate (52) and the rotating plate (53) are tightly fitted to form a physical water seal barrier inside the cup body (13). A detection groove (531) is provided on the rotating plate (53), and the four monitoring components (54) are installed inside the detection groove (531). A hole (521) is provided on the top plate (52) to cooperate with the detection groove (531). The connecting component (2) includes an electromagnet (21) and a magnetic attractor (22), which are respectively disposed on the outer side of the top of the cup body (13) and the inner side of the cover body (11). The electromagnet (21) is electrically connected to the electromagnetic lock control module of the alarm system. The rotating plate (53) is connected to the cover (11) in a transmission manner. When the cover (11) is loosened to a preset position, the rotation displacement of the cover (11) drives the rotating plate (53) to rotate, so that the hole (521) is precisely aligned with the detection groove (531) so that the liquid in the cavity (14) flows into the detection groove (531) for parallel monitoring. At the same time, the alarm system triggers the electromagnet (21) to be energized and attract the magnetic suction piece (22), locking the cover (11) in the preset position.
