Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0052] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0053] Example 1, with reference to Figure 1-3 , which is the first embodiment of the present invention, provides an adaptive oral hydration control system based on dual-channel liquid feeding, comprising:

[0054] Dual-channel straw system, auxiliary drinking straw, fluid control module, central controller and human-computer interface;

[0055] The dual-channel suction pipe system includes a main suction pipe, a secondary suction pipe, a solenoid valve, and a pressure-adjustable jet pump integrated into the main suction pipe to achieve pulsed water jetting through the Venturi effect.

[0056] The auxiliary drinking straw includes a silicone base, a main flow channel, a secondary flow channel and a port assembly;

[0057] The fluid control module includes a main water pump, a micro peristaltic pump, a micro pressure sensor array and a flow sensor;

[0058] The central controller integrates MCU, storage unit and Bluetooth module to adjust the output power of the dual pumps;

[0059] The human-machine interface includes a touch screen and physical knobs for setting injection parameters;

[0060] The solenoid valve, the pressure-adjustable jet pump, the main water pump, the micro peristaltic pump, the micro pressure sensor array, and the flow sensor are all connected to the central controller.

[0061] Furthermore, the main straw of the dual-channel straw system is made of food-grade polypropylene (PP), and the secondary straw is made of medical-grade silicone. It has flexible properties to adapt to oral movements. The solenoid valve is a miniature two-way solenoid valve, which is used to achieve independent opening and closing control of the main and secondary straws.

[0062] It should be noted that the main straw is made of food-grade polypropylene (PP) material with excellent chemical stability and temperature resistance; the inner wall of the main straw is precisely polished to reduce the resistance to liquid flow, improve the smoothness of water flow and the convenience of cleaning; the secondary straw is made of medical-grade silicone material, which has good flexibility and bendability while ensuring biocompatibility, and can deform naturally with the user's oral movement to improve wearing comfort; the miniature two-way solenoid valve used has the characteristics of fast response speed and high control precision, and can realize independent opening and closing control of the fluid passages of the main straw and secondary straw, thereby effectively avoiding liquid mixing and improving the flexibility of system regulation.

[0063] Furthermore, the fluid control module further includes a flow distribution unit, which is used to dynamically adjust the flow ratio of the main and auxiliary suction pipes according to the instructions of the central controller.

[0064] It should be noted that the flow distribution unit, as an important component of the fluid control module, has the core function of dynamically adjusting the liquid flow ratio between the main suction pipe and the auxiliary suction pipe according to the instructions issued by the central controller; this unit is composed of a multi-channel proportional control valve and a feedback adjustment mechanism, which can perform closed-loop adjustment based on real-time collected pressure and flow data to ensure that the main and auxiliary liquid outputs always maintain the set ratio in different usage scenarios; this design not only enhances the adaptability of the system, but also provides a hardware foundation for personalized flavor blending.

[0065] Furthermore, the central controller has a built-in adaptive algorithm that can automatically optimize the injection parameters according to usage habits. The storage unit is used to record user preference data. The Bluetooth module supports data synchronization with mobile terminals for remote monitoring and parameter adjustment.

[0066] The central controller has a built-in adaptive algorithm that automatically optimizes the injection parameters based on usage habits, including:

[0067] The micro pressure sensor array and flow sensor collect information about the user's oral pressure distribution, liquid flow changes, and operation time points during use, and send it to the storage unit of the central controller for recording;

[0068] The MCU performs statistical analysis on historical data in the storage unit to extract user usage patterns, including key parameters such as commonly used spray intensity ranges, preferred flavor liquid ratios, spray frequency, and duration.

[0069] Calculate the average spray intensity using the expression:

[0070]

[0071] Among them, S i represents the output power value of the main water pump during the i-th injection, and n represents the number of historical injections;

[0072] The percentage of flavored liquids used in the secondary straws is calculated as follows:

[0073]

[0074] Among them, V f,j represents the total output volume of flavor liquid in the jth use, V t,j Indicates the total volume of the primary and secondary liquids in the jth use;

[0075] Based on the extracted user behavior features, a dynamic adjustment model is established to predict the settings that the user may prefer the next time they use the app.

[0076] Set the initial value of the main water pump output power P0 = k s ·S avg +bs , where k s and b s is the empirical coefficient used to calibrate the output power range;

[0077] Set the flavor liquid output ratio in is the average proportion of historical flavors of users, k r and b r is the regulating factor;

[0078] During each use, the system continuously collects the current pressure signal p(t)p(t), flow signal q(t)q(t) and user manual adjustment input, and compares them with the prediction model to calculate the deviation. The expression is:

[0079] e p (t) = p pred (t)-p(t);

[0080] e q (t) = q pred (t)-q(t);

[0081] Update parameters using PID control strategy according to the deviation;

[0082] The output power correction term ΔP and the flavor ratio correction term ΔF are expressed as follows:

[0083]

[0084] ΔF=α·e p (t)+β·(F curr -F0);

[0085] Among them, α and β are weighting coefficients, F curr is the current setting value;

[0086] The current usage data and the revised parameters are saved to the storage unit to update the user preference database. At the same time, the latest parameters are uploaded to the mobile terminal via the Bluetooth module;

[0087] When the system is started next time, the latest user preference data is loaded, and the main water pump output power and flavor liquid ratio are initialized to achieve personalized adaptive injection control.

[0088] It should be noted that the adaptive algorithm built into the central controller is an intelligent optimization mechanism driven by user behavior data. It gradually establishes a personalized injection parameter model through continuous learning of historical usage data; the MCU analyzes key characteristics of the user's injection intensity, frequency, duration and flavor preferences, combines statistical methods to extract regular behavior patterns, and predicts the optimal parameter combination for future use based on this; the PID control strategy is used to correct the deviation between the predicted value and the actual feedback in real time, so that the system can maintain stable performance in a constantly changing usage environment; all updated parameters are recorded in the storage unit and can be uploaded to the mobile terminal via the Bluetooth module to achieve cloud synchronization and remote management of user data.

[0089] Furthermore, the human-computer interaction interface also includes a voice control module that supports voice command operation; the touch screen is used to display real-time flow curves and pressure distribution diagrams, and the physical knob has a tactile feedback function for precise parameter adjustment.

[0090] It should be noted that the design of the human-computer interaction interface fully considers the combination of operational convenience and information visualization; the voice control module is integrated with an environmental noise suppression algorithm, which can accurately recognize the user's voice commands and is suitable for special people who have difficulty operating with their hands; the touch screen is not only used to set the injection parameters, but also can display the flow curves of the main and auxiliary channels and the oral pressure distribution diagram in real time to help users intuitively understand the current status; the physical knob uses a high-precision encoder and tactile feedback technology to provide users with an accurate and comfortable parameter adjustment experience.

[0091] Furthermore, the inner diameter of the main straw is 3mm and is equipped with a variable frequency water pump for transporting drinking water. The inner diameter of the auxiliary straw is 0.5mm and is used to use a micro peristaltic pump to achieve flow control of flavored drinks. It is evenly distributed at the tongue sleeve outlet through a microfluidic channel. The solenoid valve is used to control the fluid pathways of the main straw and the auxiliary straw respectively.

[0092] It should be noted that the 3mm inner diameter design of the main straw takes into account both drinking efficiency and fluid control accuracy. Combined with a variable frequency water pump, it can achieve a variety of water supply modes from low-speed dripping to high-speed pulses; the 0.5mm small diameter of the secondary straw is particularly suitable for the micro-precision supply of flavored liquids. Through the precise metering capability of the micro peristaltic pump, microliter-level liquid volume control is achieved; the microfluidic channel evenly distributes the flavored liquid to the tongue sleeve outlet to ensure consistency in flavor perception; on this basis, the solenoid valve realizes independent control of the main and secondary flow channels, allowing the system to choose to open or close a flow channel at any time to meet complex drinking needs.

[0093] Furthermore, the flow sensor adopts the principle of non-contact optical detection and is installed inside the dual-channel pipette system to accurately measure the liquid flow rate in the main and secondary channels.

[0094] It should be noted that the non-contact optical flow sensor is based on the principle of light intensity change caused by liquid flow when an infrared light beam passes through the fluid channel, and realizes real-time monitoring of the liquid flow rate in the main and secondary channels; this type of sensor has no mechanical moving parts, avoiding the blockage, wear and cross-contamination problems that may be caused by traditional contact sensors; at the same time, it has high sensitivity and fast response characteristics, and can provide continuous and accurate flow feedback signals for the control system, thereby ensuring the stability and accuracy of the system operation.

[0095] Furthermore, a micro pressure sensor array is manufactured using MEMS technology and arranged on the surface of the auxiliary drinking straw to monitor pressure changes in different areas of the mouth and transmit the data to a central controller for analysis and processing.

[0096] It should be noted that the micro pressure sensor array adopts MEMS (Micro-Electro-Mechanical Systems) manufacturing technology, and has the characteristics of small size, high sensitivity and fast response; the array is arranged in different areas of the surface of the auxiliary drinking straw, and can synchronously collect pressure distribution data generated by the user's sucking action; the data is not only used to trigger the liquid supply mechanism, but also to judge the user's current drinking intention (such as drinking water, tasting or pausing), providing the system with a higher level of behavior recognition capability; all pressure signals are transmitted to the central controller after analog-to-digital conversion to participate in subsequent logical judgment and parameter adjustment.

[0097] In summary, through the independent flow channel design of the main straw and the auxiliary straw, combined with the pressure-adjustable jet pump, micro solenoid valve and fluid control module, the precise delivery and dynamic adjustment of drinking water and flavored liquids are achieved; the system adopts a central controller with an integrated MCU and adaptive algorithm, which can automatically optimize the injection parameters according to the user's usage habits, and provide real-time feedback on the oral status through a micro pressure sensor array and flow sensor, thereby improving control accuracy and personalized experience; the human-computer interaction interface supports touch screen display, physical knob adjustment and voice control, and the operation is convenient and intuitive; the auxiliary drinking straw adopts a bionic structure or a segmented tongue-shaped design, which fits the oral shape and enhances drinking comfort and safety; the overall solution is not only suitable for people with swallowing dysfunction, but can also be widely used in elderly care, rehabilitation medicine and personalized beverage supply scenarios.

[0098] Example 2 is the second embodiment of the present invention. This embodiment provides an auxiliary drinking straw based on a bionic tongue cover structure, which aims to improve drinking comfort and optimize liquid distribution efficiency by simulating the tongue morphology and liquid guidance mechanism, including:

[0099] Silicone base: Made of food-grade thermoplastic silicone, it has a pocket-like structure with an open top to fit the front two-thirds of the tongue. A circular, non-slip, water-repellent strip is incorporated into the silicone base to enhance wearing stability and prevent water from mixing with flavored liquids.

[0100] Main flow channel: no less than 8 radially distributed small channels, connected to the main plug hole through the main diversion groove. Users can choose to open or close certain channels through the built-in channel plug to adjust the liquid flow path and spray intensity;

[0101] Secondary flow channel: Independent of the main flow channel, it is connected to the micro-flow hole through the secondary diversion groove, and directional covers the dense taste bud area on the tip of the tongue, ensuring that the flavor liquid is accurately delivered without being diluted by water;

[0102] Port assembly: integrated into the rear end of the tongue sleeve, with a main plug hole and a secondary plug hole, which are connected to the main and secondary suction pipes of the system respectively. A sealing ring is provided at the interface to prevent liquid leakage;

[0103] Drainage structure: There is a honeycomb drainage groove at the bottom of the tongue to facilitate the natural drainage of residual liquid, avoiding stagnation and causing odor or bacterial growth;

[0104] The specific steps are:

[0105] S1. The user wears the bionic tongue cover on the tongue surface and generates a negative pressure signal through natural sucking action;

[0106] S2, the micro pressure sensor array embedded in the surface of the tongue cover detects the pressure change and transmits the signal to the central controller;

[0107] S3. After the central controller determines that the water is in a normal drinking state, it starts the main water pump and the micro peristaltic pump;

[0108] S4: The main water pump drives the drinking water through the main suction pipe, the main plug hole, the main diversion trough, and the open main flow channel to the tongue root area, avoiding the taste bud sensitive area.

[0109] S5. At the same time, the micro peristaltic pump controls the flavor liquid to flow through the auxiliary suction pipe → auxiliary plug hole → auxiliary diversion groove → micro flow hole, and sprays it to the taste bud area on the tip of the tongue in the form of atomization (micropore spacing 2mm, inner diameter 0.2mm);

[0110] S6. After the liquid is used up, the remaining liquid will be collected along the drainage trough to the drain outlet and discharged naturally by gravity;

[0111] S7, the flow sensor monitors the liquid output of the main and auxiliary channels in real time, and the central controller adjusts the water pump power or closes the solenoid valve accordingly;

[0112] S8. The system continuously records the user's drinking behavior data, such as spray time, flow rate, frequency, etc., for subsequent adaptive algorithm optimization parameter configuration.

[0113] In summary, the bionic structure fits the shape of the tongue, improves wearing comfort, and is suitable for people with swallowing disorders; it supports independent control of multi-channel liquids, effectively preventing the mixing of clean water and flavored liquids; the adjustable mainstream channel design enhances the user's ability to control the direction and intensity of the water flow; the drainage structure design improves hygiene and safety, and reduces the health risks caused by liquid residue; in conjunction with the adaptive algorithm of the central controller, it can automatically optimize the injection strategy according to user habits, thereby improving the intelligence level of the equipment.

[0114] Example 3 is the third embodiment of the present invention. This embodiment provides an auxiliary drinking straw based on a tongue-shaped segmented structure. The straw is modularly designed to divide the entire tongue into multiple functional areas, each of which can independently control liquid supply, including:

[0115] Silicone base: Made of medical-grade flexible silicone material, with a thickness of 2-3mm, a width of 20-40mm, and a length of 15-40mm. The overall shape mimics the contours of the tongue, and the surface is provided with tongue-like papillae to enhance the tactile realism.

[0116] Main flow pipe: Designed with a 30° inclination angle, it connects to the main suction pipe through the main plug hole and is responsible for quickly delivering drinking water to the throat area;

[0117] Cross guide vane: installed at the end of the main flow pipe to evenly disperse the water flow and reduce splashing and impact force;

[0118] Drainage grooves: distributed on both sides of the silicone base, used to guide the residual liquid to the rear for discharge;

[0119] Diverter cavity: located in the middle of the tongue, connected to the secondary plug hole, receiving the flavor liquid from the secondary straw;

[0120] Diversion grooves and micro-circulation holes: Multiple small channels extend from the diversion cavity, and ultimately the flavor liquid is evenly distributed to various sensitive areas on the tongue through the micro-circulation holes;

[0121] Port assembly: equipped with a main plug hole and a secondary plug hole, which are connected to the main straw and the secondary straw respectively, supporting quick plugging and replacement.

[0122] The specific steps are:

[0123] S1. The user puts the tongue-shaped straw into their mouth. The sucking action triggers the Venturi effect, allowing the system to sense the initial contact force.

[0124] S2, the micro pressure sensor array collects pressure change information and sends it to the central controller for analysis;

[0125] S3: After the controller recognizes the "flavored drink + basic hydration" mode, it first activates the auxiliary straw to spray concentrated coffee droplets (particle size 50-80μm) for 3 seconds to form a taste memory layer on the tip of the tongue;

[0126] S4. At 3.1s, the main pipette is activated to spray 15ml±1ml of room-temperature water at a speed of v=2.5m / s±0.2m / s, and the water is swallowed directly.

[0127] S5. The drainage grooves on the surface of the tongue quickly divert the remaining liquid to the throat, reducing retention;

[0128] S6. The system independently controls the opening and closing of the main suction pipe and the auxiliary suction pipe through the solenoid valve to ensure that the two liquids do not mix;

[0129] S7, the flow sensor and pressure sensor provide real-time feedback on the liquid flow status, and the central controller dynamically adjusts the output power of the main water pump and micro peristaltic pump accordingly;

[0130] S8. After use, all operation data are recorded in the storage unit for subsequent adaptive algorithm learning and optimization.

[0131] In summary, the segmented structure improves adaptability and is suitable for a variety of oral shapes and drinking needs; multiple water outlet forms (centralized spray, atomization, diffusion) meet diverse scenarios; regionalized liquid control is achieved to enhance safety and controllability; multiple drinking mode switching is supported (basic drinking water, flavor enhancement, throat moistening) to improve device functionality; and remote monitoring and personalized services are achieved in conjunction with adaptive algorithms and Bluetooth modules.

[0132] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
