Description

Technical Field

[0001] This application relates to the field of smart water cup technology, and in particular to a smart water cup and its working method. Background Technology

[0002] With the popularization of healthy living concepts, scientific drinking water, as an important part of daily health management, is receiving increasing attention. Traditional drinking water management methods mainly rely on users' subjective memory or use simple counters for recording. These methods have significant errors and cannot effectively identify actual drinking actions, making it difficult to form a reliable data foundation.

[0003] In recent years, some so-called "smart water bottles" with weight sensing functions have appeared on the market, aiming to help users manage their drinking habits by quantifying drinking data. However, existing products of this type have many limitations in their technical implementation, resulting in poor practical application effects. First, in terms of the core drinking behavior recognition, existing products usually rely solely on a single weighing sensor to measure changes in water volume. This simple weight detection scheme cannot effectively distinguish between distinct usage scenarios such as "drinking," "filling," "pouring and discarding," and "washing and shaking," making it prone to misjudgments and recording non-drinking actions as valid drinking, seriously affecting the accuracy of the data.

[0004] Secondly, existing designs have significant shortcomings in measurement stability and anti-interference capabilities. When the cup is tilted, the sloshing of the liquid inside causes drastic fluctuations in the instantaneous reading of the weighing sensor, introducing significant measurement errors. Many products lack effective attitude sensing and data compensation mechanisms, failing to provide stable and reliable weight data in dynamic usage scenarios. Furthermore, in terms of mechanical structure design, some products fail to adequately consider the long-term operational stability of the sensor module. Common defects include uneven force on the sensor, or stress interference from non-perpendicular directions due to unreasonable installation structures. These can lead to zero-point drift or decreased sensitivity of the sensor, resulting in gradually increasing measurement deviations and reduced reliability over long-term use.

[0005] Finally, in terms of user experience and system integration, existing products have relatively limited functionality. Most products lack intuitive and immediate human-computer interaction feedback mechanisms (such as light or sound prompts based on drinking status), making it difficult for users to easily obtain their current drinking status. Furthermore, their data interaction methods are often limited to simple displays on the device itself or one-way transmission via basic Bluetooth connections, failing to deeply integrate with mobile internet platforms and thus unable to form a closed-loop health management service from data collection and analysis to personalized reminders.

[0006] In summary, existing smart water cups have technical deficiencies that urgently need improvement in areas such as accurate recognition of drinking behavior, resistance to interference in dynamic environments, long-term structural stability, and intelligent human-computer interaction, which limit their application value and user experience in real life. Summary of the Invention

[0007] This application provides a smart water cup and its working method to at least solve the technical problems of inaccurate drinking behavior recognition, easy interference in measurement, and unstable structure of existing smart water cups.

[0008] To achieve the above objectives, this application provides a smart water cup, including a cup body and a monitoring module disposed at the bottom of the cup body. The monitoring module includes a housing, a weighing sensor, a battery, and a circuit board. The weighing sensor, the battery, and the circuit board are electrically connected and installed inside the housing. The weighing sensor is disposed in the central region inside the housing. The circuit board integrates an inertial sensor module, an analog-to-digital converter module, and a main control chip. The housing is provided with a light-emitting component electrically connected to the circuit board. The light-emitting component cooperates with the output signal of the circuit board to perform observable light characteristic transformations.

[0009] In some embodiments, the monitoring module includes a limiting member that cooperates with the weighing sensor, the limiting member being adjacent to and spaced apart from the weighing sensor in the axial direction of the cup body.

[0010] In some embodiments, the limiting member is spaced 0.8 to 1 mm from the weighing sensor.

[0011] In some embodiments, the housing is provided with a positioning post extending axially, and the circuit board, the limiting member and the weighing sensor are mounted on the positioning post.

[0012] In some embodiments, the bottom of the housing is provided with flexible contacts.

[0013] In some embodiments, a support member is provided between the contact member and the weighing sensor, and the support member abuts against both the contact member and the weighing sensor.

[0014] In some embodiments, the support member has support portions evenly distributed circumferentially on the side near the contact member, and the support portions abut against the contact member.

[0015] In some embodiments, the light-emitting components are disposed on the outside of the housing and distributed circumferentially.

[0016] This application also provides a method for operating a smart water bottle based on any one of the above-described methods, including the following steps:

[0017] Step S1: Amplify and convert the output signal of the weighing sensor through the analog-to-digital conversion module to obtain an accurate weight value;

[0018] Step S2: Detect the cup's attitude angle using the inertial sensor module to determine the cup's state;

[0019] Step S3: Combine weight change trends with posture data to establish a behavior recognition model;

[0020] Step S4: The main control chip processes the above data and uploads it to the terminal;

[0021] Step S5: Set drinking water goals and reminder strategies through the terminal and display them through the light-emitting component.

[0022] In some embodiments, the behavior recognition model includes:

[0023] When the weight decreases by more than the preset threshold, the duration exceeds the preset time, and the posture angle exceeds the preset angle, it is determined as a "drinking action".

[0024] If the weight increases rapidly, it is determined that "water has been added";

[0025] If the weight is close to zero and remains unchanged for a long time, it is determined to be an "empty cup awaiting cleaning".

[0026] Based on the above, the advantages of this application's technical solution compared to the prior art are:

[0027] 1. By integrating data from high-precision weighing sensors and inertial sensors, it accurately identifies real drinking behavior and effectively overcomes measurement errors caused by cup tilting and liquid sloshing.

[0028] 2. An optimized combination of hard plastic support and silicone buffer structure is adopted to ensure that the sensor is subjected to uniform force and is not affected by lateral stress, thereby ensuring the stability and consistency of long-term measurements;

[0029] 3. It integrates an intuitive light ring feedback mechanism and deeply links with the terminal through the main control chip, enabling it to provide users with a closed-loop healthy drinking water management service. Attached Figure Description

[0038] This application provides a smart water cup, including a cup body and a monitoring module disposed at the bottom of the cup body. The monitoring module includes a housing, a weighing sensor, a battery, and a circuit board. The weighing sensor, battery, and circuit board are electrically connected and installed in the housing. The weighing sensor is disposed in the central area of ​​the housing. The circuit board integrates an inertial sensor module, an analog-to-digital converter module, and a main control chip. The housing is provided with a light-emitting component electrically connected to the circuit board. The light-emitting component cooperates with the output signal of the circuit board to perform observable light characteristic transformation.

[0039] This application also provides a working method based on the above-mentioned smart water cup, including the following steps:

[0040] Step S1: Amplify and convert the output signal of the weighing sensor through the analog-to-digital conversion module to obtain an accurate weight value;

[0041] Step S2: Detect the cup's attitude angle using the inertial sensor module to determine the cup's state;

[0042] Step S3: Combine weight change trends with posture data to establish a behavior recognition model;

[0043] Step S4: The main control chip processes the above data and uploads it to the terminal;

[0044] Step S5: Set drinking water goals and reminder strategies through the terminal and display them through the light-emitting component.

[0045] Implementation, for example Figures 1-3 As shown, a smart water cup includes a cup body 1 and a monitoring module disposed at the bottom of the cup body 1. The monitoring module includes a housing 2, a load cell 3, a battery 4, a circuit board 5, a limiting member 6, a support member 7, a contact member 8, and a light-emitting component 9. The load cell 3, battery 4, and circuit board 5 are electrically connected and installed inside the housing 2, while the light-emitting component 9 is electrically connected to the circuit board 5 and installed outside the housing 2. The load cell 3 is disposed in the central region inside the housing 2. The limiting member 6, load cell 3, and support member 7 are arranged along the axial direction of the cup body 1. The limiting member 6 is located above the load cell 3, and the support member 7 is located below the load cell 3. The limiting member 6 cooperates with the load cell 3 and is spaced apart, while the support member 7 abuts against the load cell 3. The contact member 8 is made of a flexible material, such as soft silicone, and is located at the bottom of the housing 2. It serves as a soft contact medium to enhance cushioning, prevent damage to the sensor from hard contact, and also has good waterproof performance. The support 7 is located between the contact 8 and the load cell 3, and abuts against both the contact 8 and the load cell 3 respectively. It can be used to support and limit the deformation of the silicone and ensure that the force applied to the load cell 3 is evenly distributed.

[0046] Furthermore, the load cell 3 is a full-bridge load cell, which adopts a four-pin full-bridge strain gauge structure made of metal, with a range of 1mm and a sensitivity of not less than 1mV / V. It is installed in the center of the support 7 and detects the change in the total weight of the cup 1.

[0047] Furthermore, the support member 7 has support portions 7.1 evenly distributed circumferentially on the side near the contact member 8. The support portions 7.1 abut against the contact member 8, further enhancing the support effect of the support member 7.

[0048] Furthermore, the limiting member 6 and the load cell 3 are positioned adjacent to each other in the axial direction of the cup body 1 and spaced apart by 0.8~1mm. This gap setting can prevent the load cell 3 from exceeding the full range of 1mm and prevent overload damage.

[0049] Furthermore, circuit board 5 integrates an inertial sensor module, an analog-to-digital converter module, and a main control chip. The inertial sensor module is an MPU6050 six-axis inertial sensor module, the analog-to-digital converter module is an HX711 high-precision ADC chip, and the main control chip is an ESP32-PICO-D4 microcontroller. Circuit board 5 also integrates a USB serial port writing circuit and a lithium battery charging and discharging management circuit.

[0050] Specifically, the HX711 high-precision ADC chip is connected to the full-bridge load cell via an excitation voltage source, with a sampling frequency greater than 10Hz and a resolution of up to 0.01g. The MPU6050 six-axis inertial sensor module is used to collect the pitch and roll angles of the cup body 1, and combined with the weight change trend to determine whether a drinking action has occurred. The ESP32-PICO-D4 microcontroller communicates with the user terminal (such as a WeChat mini-program linked to the user's mobile phone) via Wi-Fi protocol, uploading drinking data and receiving instructions.

[0051] Furthermore, the light-emitting component 9 is an LED ring distributed circumferentially outside the housing 2. The light-emitting component 9 can perform observable light characteristic changes in conjunction with the signal output from the circuit board 5, displaying information such as battery level, current water level, and reminder status through changes in brightness, color, and frequency. For example, the LED ring can emit different colors of light according to the current status: green indicates normal, blue indicates a reminder, and red indicates an abnormality.

[0052] Furthermore, the housing 2 is equipped with a USB-C opening, four positioning posts 2.1, and three sets of reinforcing ribs 2.2. The positioning posts 2.1 and reinforcing ribs 2.2 extend axially to improve the structural rigidity of the housing 2 and prevent sensor displacement caused by external pressure. The positioning posts 2.1 are equidistantly distributed circumferentially within the housing 2, and the circuit board 5, limiting member 6, support member 7, and weighing sensor 3 are mounted on the positioning posts 2.1. A waterproof silicone plug is inserted at the USB-C interface for waterproofing.

[0053] Furthermore, the support member 7 includes an adjusting screw 7.2 disposed thereon. The adjusting screw 7.2 is used to fix the support member 7, and also serves to abut against the load cell 3. An adjusting nut 7.3 is provided in cooperation with the adjusting screw 7.2. The adjusting screw 7.2 and the adjusting nut 7.3 work together to apply a slight prestress to the elastic deformation area of ​​the load cell 3 to optimize its linear response characteristics.

[0054] Furthermore, based on the above-mentioned working method of the smart water bottle, the following steps are included:

[0055] Step S1: Amplify and convert the output signal of the weighing sensor through the analog-to-digital conversion module to obtain an accurate weight value;

[0056] Step S2: Detect the cup's attitude angle using the inertial sensor module to determine the cup's state;

[0057] Step S3: Combine weight change trends with posture data to establish a behavior recognition model;

[0058] Step S4: The main control chip processes the above data and uploads it to the terminal;

[0059] Step S5: Set drinking water goals and reminder strategies through the terminal and display them through the light-emitting component.

[0060] Specifically,

[0061] In step S1, the output signal of the full-bridge load cell is amplified and converted from analog to digital by the HX711 high-precision ADC chip to obtain the accurate weight value.

[0062] In step S2, the attitude angles (pitch angle and roll angle) of the cup are detected by the MPU6050 six-axis inertial sensor module to determine whether the cup is in a "tilting" state.

[0063] In step S3, a behavior recognition model is established by combining the weight change trend and posture data. When the weight decreases by more than a preset threshold (e.g., 5g), the duration is greater than a preset time (e.g., 1s), and the posture angle is greater than a preset angle (e.g., 30°), it is determined as "drinking water"; if the weight increases rapidly, it is determined as "adding water"; if the weight is close to zero and does not change for a long time, it is determined as "empty cup waiting to be cleaned".

[0064] In step S4, after the ESP32-PICO-D4 microcontroller processes the above data, it connects to the user's bound WeChat mini-program via Wi-Fi and uploads historical drinking records.

[0065] In step S5, users can set daily target water intake and time-segmented reminder strategies in the mini-program;

[0066] The LED ring flashes different colors depending on the current status: After the motherboard confirms that the data feedback is normal, the ring light strip indicates the progress of the set drinking water target in the form of a progress bar. It is blue when charging, green when fully charged, and flashes red when the battery is low.

[0067] Those skilled in the art should understand that the technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments have been described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
