[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] like Figure 1 、 Figure 2 As shown, the embodiment of the utility model provides a drinking device with intelligent water amount reminder, including a cup body, a main control module is arranged inside the cup body, the input end of the main control module is respectively connected to the water level detection module, the infrared detection module, the button module and the power module, and the output end of the main control module is connected to the voice module;

[0030] The infrared detection module includes a first photoelectric sensor and a second photoelectric sensor, and the first photoelectric sensor and the second photoelectric sensor are respectively arranged on the side walls of both sides of the cup body close to the bottom.

[0031] In this embodiment, the cup body is made of a non-metallic material that is resistant to high temperatures, drop-resistant, and environmentally friendly, and has good heat insulation properties to prevent the blind from being scalded during use.

[0032] In this embodiment, the main control module is implemented using a single-chip microcomputer. Its input is connected to the water level detection module, infrared detection module, and keypad module, respectively, and its output is connected to the voice module. The main control module receives the detection results from these modules and, based on the detection results, issues corresponding instructions to the voice module, driving the voice module to emit the corresponding audio prompts. It should be noted that the microcontroller's reception, analysis, and determination of detection results, as well as the issuance of corresponding instructions based on the detection results, are existing functions of the microcontroller and do not involve software improvements.

[0033] In some implementations, the main control module uses an STM32F103 main control chip. The model of the main control chip can be flexibly selected according to actual conditions and is not specifically limited in this embodiment.

[0034] In this embodiment, if Figure 1 、 Figure 4As shown, the power module is connected to the main control module to provide power to it. The power module uses a high-performance rechargeable battery, which is set inside the cup body and charged through the charging port at the bottom of the cup body to ensure the normal use of the drinking water device.

[0035] Specifically, such as Figure 4 As shown, the first output terminal VCC1 of the power module is connected to the first main power pin VDD_1 of the main control module and the first end of the third resistor R3, respectively. The first main power pin VDD_1 is connected to the second main power pin VDD_2 and the third main power pin VDD_3 of the main control module, respectively. The second end of the third resistor R3 is connected to the analog power pin VDDA of the main control module. A second capacitor C2, a third capacitor C3, and a fourth capacitor C4 are connected in parallel between the first output terminal VCC1 of the power module and the first main power pin VDD_1 of the main control module, and then to ground. A seventh capacitor C7 and an eighth capacitor C8 are connected in parallel between the third resistor R3 and the analog power pin VDDA, and then to ground. The power module supplies power to the main control module, i.e., the microcontroller, via its first output terminal VCC1.

[0036] Furthermore, the resistance of the third resistor R3 is 10R, which is a current limiting resistor. It limits the current flowing through the microcontroller to prevent excessive current from damaging the microcontroller. At the same time, it can also play a role in voltage division to prevent the microcontroller from being subjected to excessively high voltage; the capacitance values ​​of the second capacitor C2, the third capacitor C3, the fourth capacitor C4, the seventh capacitor C7, and the eighth capacitor C8 are all 104, which are decoupling capacitors. The decoupling capacitor reduces the impact of unstable current on the microcontroller through its buffering effect, and is used to provide a stable power supply and reduce the noise coupled from components to the power supply end.

[0037] Specifically, such as Figure 4 As shown, the second output terminal VCC2 of the power module is connected to the anode of the first diode D1, the cathode of the first diode D1 is connected to the backup power pin VBAT of the main control module and the first end of the fifth capacitor C5, respectively. The backup power pin VBAT of the main control module is connected to a reference voltage source to receive a reference voltage. The second end of the fifth capacitor C5 is connected to the first end of the sixth capacitor C6, and the second end of the fifth capacitor C5 is grounded. The second end of the sixth capacitor C6 is connected to the reset pin NRST of the main control module and the first end of the fourth resistor R4, respectively. The second end of the fourth resistor R4 is connected to the third output terminal VCC3 of the power module. The power module also supplies power to the microcontroller through its second and third output terminals.

[0038] Furthermore, the reference voltage source provides a stable and accurate voltage reference for the microcontroller, provides a standard for the conversion between analog signals and digital signals, and ensures the accuracy and reliability of the microcontroller's operation.

[0039] Furthermore, the fourth resistor R4 has a resistance of 10K and serves as a current-limiting resistor. The fifth and sixth capacitors C5 and C6 each have a capacitance of 104 and serve as decoupling capacitors. The resistance and capacitance of each resistor and capacitor can be flexibly set according to actual conditions and are not specifically limited in this embodiment.

[0040] The input voltage of the main control module is 3.3 V, that is, the voltage connected to the first output terminal VCC1, the second output terminal VCC2, and the third output terminal VCC3 of the main control module is 3.3 V. The output voltage of the power module is 5 V, which is reduced to 3.3 V by the step-down chip.

[0041] Specifically, such as Figure 5 As shown, the input terminal Vin of the step-down chip is connected to the 5V output terminal of the power module, and the output terminal Vout of the step-down chip is connected to the 3.3V output terminal of the power module. The input terminal Vin of the step-down chip is connected to the ninth capacitor C9 and then to ground, and the output terminal of the step-down chip is connected to the tenth capacitor C10 and the eleventh capacitor C11 and then to ground.

[0042] In some implementations, the step-down chip uses the ME6210A33M3G model, which can be flexibly selected according to actual conditions.

[0043] In the drinking water device, the power module is also connected to the water level detection module, infrared detection module, key module and voice module respectively, and provides power to each module. The input voltage of the water level detection module, infrared detection module, key module and voice module is 5V.

[0044] In this embodiment, the water level detection module uses a capacitive sensor mounted on the inner wall of the cup to detect changes in the water level in the cup. Based on the principle of capacitance, changes in the water level in the cup cause changes in the medium surrounding the sensor electrode, which in turn causes a change in the capacitance value, achieving the purpose of water level detection. When the water level in the cup changes, the water level detection module outputs the current capacitance value to the main control module, which receives the current capacitance value and calculates and converts it into a water level percentage.

[0045] For example: when the cup is full, the capacitance value is the maximum , the minimum value is when the cup is empty The actual capacitance value is , then the water percentage is:

[0046] .

[0047] The water volume thresholds of 40%, 50%, 60%, 70%, 80% and 90% are pre-set.

[0048] The main control module receives capacitance data from the water level detection module and continuously monitors the water percentage in the cup. Based on two readings of water level measured at a predetermined interval (e.g., 50ms), the main control module determines whether pouring begins when the water level increases by 1% and stops when the water level no longer increases by 1%. During the pouring process, if the water level reaches a preset threshold, the main control module sends a command to the voice module to announce the current water level. The main control module also sends a command to the voice module to announce the current water level based on electrical signals received from the keypad or infrared detection module. The voice module then generates a voice prompt indicating the current water level in the cup.

[0049] In some embodiments, a differential liquid level module is selected as the capacitive sensor.

[0050] Specifically, such as Figure 3 As shown, the water level detection module uses an MC12G chip. The first capacitor positive pin C0P of the water level detection module is connected to the positive electrode of the detection capacitor Cap Sensor, the first capacitor negative pin C0N of the water level detection module is connected to the negative electrode of the detection capacitor Cap Sensor, the second capacitor positive pin C1P is connected to the positive electrode of the matching capacitor Cap, and the second capacitor negative pin C1N is connected to the negative electrode of the matching capacitor Cap. The matching capacitors are used to provide a reference for the corresponding detection medium (i.e., the recommended capacitance values ​​for measuring different media provided by the water level detection module) to calibrate the accuracy of the measured capacitance value. The water level detection module's power pin VDD is connected to the output of the power module, and the ground pin VSS is grounded, providing power to the module.

[0051] The water level detection module's power pin VDD is connected in series with a first capacitor C1 and then to ground. It is also connected in series with a first pull-up resistor R1 and connected to the water level detection module's serial data pin SDA. The water level detection module's power pin VDD is also connected in series with a second pull-up resistor R2 and connected to the water level detection module's serial clock pin SCL. The main control module (microcontroller) uses an open-drain output and lacks high-level load capability. Pull-up resistors (i.e., first and second pull-up resistors R1 and R2) are required to ensure a high-level signal output.

[0052] The serial data pin SDA of the water level detection module is connected to the first I / O pin PB8 of the main control module, which is used to input the capacitance value change data to the main control module; the serial clock pin SCL of the water level detection module is connected to the second I / O pin PB7 of the main control module, which is used to input the clock signal to the main control module and control the rhythm of data transmission through the clock signal.

[0053] Through the above technical solution, capacitive liquid level detection is combined with percentage water volume calculation. Compared with traditional liquid level detection, this innovative method can provide more accurate and intuitive water volume information, allowing blind people to understand the water volume in the cup more clearly.

[0054] In this embodiment, the infrared detection module includes a first photoelectric sensor and a second photoelectric sensor, each located on the sidewalls of the cup body, near the bottom. Utilizing the properties of light, when a blind person approaches the cup, the sensors emit light. This light is reflected by the body and received by the sensors, generating an electrical proximity signal that is transmitted to the main control module. Based on the proximity signal, the main control module sends a voice prompt indicating the current water level. The voice module then issues a voice prompt indicating the percentage of water in the cup, allowing the blind person to easily identify the cup's location and initial water level.

[0055] Specifically, such as Figure 3 As shown, the output ends of the first photoelectric sensor and the second photoelectric sensor are respectively connected to the third I / O pin PA0 of the main control module, and the proximity electrical signal generated by the photoelectric sensor (ie, proximity sensor) is sent to the main control module through the third I / O pin PA0.

[0056] It should be noted that the single-chip microcomputer adopts edge trigger mode when receiving the proximity electrical signal sent by the infrared detection module. Only when the received signal changes will it send the current water volume broadcast instruction to the voice module.

[0057] The above technical solution places two photoelectric sensors on the side of the cup, near the bottom. Adjusting the sensor angles allows for better all-around coverage. This innovative layout ensures that blind people are detected regardless of the direction they approach the cup. This allows them to detect the cup's location and the initial level of water in the cup based on the sound, significantly improving their convenience.

[0058] In this embodiment, if Figure 2 As shown, the button module is located at the top of the cup handle and has a protrusion that can be felt by a blind person. When the button module is pressed, it sends an electrical signal to the main control module. The main control module receives the signal and controls the voice module to announce the current water level in the drinking device, i.e., the cup.

[0059] Specifically, such as Figure 3 As shown, the input end of the button (i.e., the key module) is connected to the input pin PC13 of the main control module. When the button is pressed, an electrical signal is sent to the main control module.

[0060] In the embodiment, the voice module adopts a BY8002-16P voice module, which is internally provided with an SD card. The audio for prompting different water amounts is pre-stored in the SD card, and the SD card is connected with the voice module. The main control module receives the capacitance value data sent by the water level detection module. When the current capacitance value changes compared with the last received capacitance value, the water amount percentage in the cup is calculated according to the capacitance value data. When the main control module receives the electric signal sent by one or more infrared detection modules or the key module, the current water amount broadcasting instruction is sent to the voice module according to the communication protocol, and the voice module is driven to send the corresponding water amount percentage sound prompt.

[0061] For example, when the water amount is less than 40%, the corresponding audio is "water amount is less than 40%. The water amount is insufficient. Please pour water." When the water amount is more than 90%, the audio is "attention, the water is full." When the water amount is between (40%, 90%), a corresponding audio is played for each threshold. For example, "the current water level is 60%." When the water amount is between [50%, 70%], "the water amount is moderate. Please drink with confidence" is played after the water amount is played.

[0062] Specifically, as shown in the figure, Figure 3 The voice module includes a voice chip, a power amplifier module and a loudspeaker connected in sequence. The signal receiving pin RX of the voice chip is connected with the fourth I / O pin PA10 of the main control module, and the main control module sends an instruction to the voice chip through the data input pin RX. The signal sending pin TX of the voice chip is connected with the fifth I / O pin PA9 of the main control module, and there is a handshake protocol between the voice module and the main control module, which is used to improve the accuracy of signal transmission. The first sound pin SPK1 of the voice chip is connected with the positive electrode of the loudspeaker through the power amplifier module, and the second sound pin SPK2 of the voice chip is connected with the negative electrode of the loudspeaker through the power amplifier module. The loudspeaker receives the audio signal of the voice chip and sends a sound prompt.

[0063] The loudspeaker and the power amplifier module are connected with the power module and are powered by the power module. The input voltage of the loudspeaker and the power amplifier module is 5V. The power amplifier module is used to amplify the audio signal output by the voice chip.

[0064] Through the above technical solution, the voice module can increase customized voice content and multi-stage water amount threshold prompts. The voice module adopts BY8002-16P, which can not only provide regular prompts such as "water amount is less than 40%" and "the current water level is 60%" according to the water amount percentage, but also customize more warm and specific prompts such as "water amount is insufficient. Please pour water", "attention, the water is full" and "water amount is moderate. Please drink with confidence" for the special needs of the blind. At the same time, multiple detailed water amount thresholds (40%, 50%, 60%, 70%, 80%, 90%) are set, and each threshold has a corresponding specific voice prompt, so that the blind can more accurately grasp the water amount.

[0065] In the embodiment, as shown in Figure 3 the connection circuit of the water level detection module, the infrared detection module, the key module, the voice module and the main control module, the main control module is further provided with a crystal oscillator circuit, that is Figure 3 X1, X2 and the corresponding connection relationship, provide basic clock signal for the main control module (single-chip microcomputer), ensure that each part can keep synchronous operation. The crystal oscillator circuit is a common peripheral circuit of single-chip microcomputer, which provides stable and accurate single-frequency oscillation for single-chip microcomputer system and other electronic equipment, and provides accurate and stable clock signal, which belongs to the existing circuit structure, and will not be described here.

[0066] Working principle is described in detail:

[0067] The water level detection module in the drinking water device (i.e. water cup) monitors the water volume change in the cup body in real time, and outputs the current capacitance value to the main control module when the water volume changes. The main control module receives the capacitance value, calculates and converts it into water volume percentage.

[0068] The main control module judges according to the water volume at two intervals, and judges that the water is started to be poured when the water volume increases by 1%, and judges that the water is stopped to be poured when the water volume no longer increases by 1%. In the process of pouring water, the main control module monitors the water volume in real time. Once the water volume reaches a certain preset water volume threshold, the main control module sends a current water volume broadcast instruction to the voice module, and the voice module issues a voice prompt of the current water volume according to the current water volume broadcast instruction. That is, in the process of continuous pouring, the voice module will broadcast the threshold water volume when the water volume reaches a certain preset water volume threshold. For example, water volume 40%, water volume 60%, water volume 90%, etc. The user can judge whether to continue pouring according to the voice broadcast of the water volume to prevent water overflow.

[0069] The main control module also sends a current water volume broadcast instruction to the voice module according to the received electric signal sent by the key module or the infrared detection module, and the voice module issues a voice prompt of the current water volume in the cup according to the current water volume broadcast instruction.

[0070] The problem that the blind person cannot accurately perceive the water level when pouring water is solved, and a series of risks such as scalding and water overflow in the process of drinking water are reduced. From the perspective of the blind group, the purpose is to make technology better serve the blind group and provide practical convenience for their life.

[0071] Although the specific embodiments of the utility model are described above in combination with the drawings, it is not a limitation on the protection scope of the utility model, and those skilled in the art should understand that various modifications or deformations made by those skilled in the art on the basis of the technical solutions of the utility model without creative labor are still within the protection scope of the utility model.
