Description

Technical Field

[0001] This utility model belongs to the technical field of health-preserving kettles, specifically relating to a health-preserving kettle with lamp keys. Background Technology

[0002] With the increasing health awareness of the people and the faster pace of life, health pots with heating and stewing functions have become the mainstream category of small home appliances. Their application scenarios have gradually extended from daytime tea preparation to nighttime warm drinks, sleep aid and health care. Health pots on the market have initially achieved intelligent upgrades, with some products integrating voice interaction functions. Users can complete operations such as power on / off, temperature adjustment and stewing mode selection through voice commands without having to manually touch the buttons, thus improving the convenience of operation.

[0003] While existing health-preserving kettles have achieved basic functions such as brewing tea and keeping it warm, and some models have added intelligent designs such as voice interaction and status prompts, there is still a gap in functionality regarding user emotional regulation: users need to wait 3 to 10 minutes during the tea brewing process, which often leads to irritability due to work interruptions. Moreover, in the workplace environment, it is inconvenient for users to use stress-relief tools alone, so stress-relief activities need to be integrated into daily operations (such as filling water and starting the tea brewing process) to avoid abruptness. However, the operation interface of traditional health-preserving kettles is mostly a single button or touch screen, with a fixed interaction form, which cannot meet the user's emotional guidance needs through multi-sensory feedback (tactile pressing + visual lighting). Utility Model Content

[0004] The purpose of this invention is to provide a health-preserving kettle with piano keys to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a health-preserving kettle with piano keys, comprising:

[0006] A base, wherein a glass kettle body is provided on the top of the base and a heating plate is provided at the bottom of the glass kettle;

[0007] The piano keys are located at the front end of the base and can be pressed continuously to make the lights on the piano keys flash.

[0008] The hoop is fixed to the top of the glass pot body by screws. A handle is fixed to one side of the hoop by screws, which provides a point of leverage for the user to hold the glass pot body and make it easy to lift the glass pot. This clarifies the basic structural components of the health pot. The base supports the glass pot body, the heating plate provides a heat source for heating the liquid inside the pot, and the piano key lamp meets the need for soft auxiliary lighting at night. The hoop and screws work together to fix the handle, providing a stable point of leverage for the user to lift the glass pot body.

[0009] Preferably, the glass kettle body is provided with a lid on the top and silicone is fitted on the bottom surface of the lid. The bottom of the lid is fixed with an inner liner by screws. The top of the lid is connected to a handle. The lid closes the opening at the top of the glass kettle body. The silicone enhances the sealing between the lid and the kettle body. The inner liner improves the installation stability of the silicone and the structural strength of the lid. The handle makes it convenient for users to open the lid and avoids burns to their hands.

[0010] Preferably, a teapot support is connected between the base and the glass teapot body. The teapot support is equipped with an upper coupler, which is screwed to the heating plate. The teapot support serves to support the glass teapot body and provide heat insulation, preventing excessive heat transfer from the heating plate to the base. The upper coupler enables conductive connection between the heating plate and the external circuit, ensuring a heating power supply path.

[0011] Preferably, a lower coupler is fixed inside the base by screws, and a computer board is provided inside the base with a speaker electrically connected to it. The lower coupler and the upper coupler work together to realize the on / off control of the heating plate circuit. The computer board serves as the control center of the health pot, receiving and processing various signals and sending control commands to each actuator.

[0012] Preferably, the top of the base is provided with several buttons, and springs are fitted at the bottom of the buttons and the bottom of the piano keys. The top of the base is also provided with a display screen. The buttons provide users with a manual operation mode to deal with the failure of voice commands or emergency operation scenarios. The springs ensure that the buttons and piano keys can be reset after being pressed. The display screen intuitively displays the current temperature, working mode and other status information of the health pot.

[0013] Preferably, the bottom of the base is fixed with a bottom cover by screws, and a power cord is provided on one side of the base. The bottom cover protects the electrical control components inside the base from dust and water stains, and facilitates disassembly and maintenance later. The power cord introduces external power to the various electrical control components of the health pot to ensure normal power supply to the equipment.

[0014] Preferably, a handle cover is screwed onto the handle, covering the screw connection part of the handle. This not only beautifies the product appearance and prevents the screw from scratching the user, but also enhances the structural strength of the handle and extends its service life.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) The light piano key located at the front of the base supports continuous pressing to trigger light flashing, which firstly creates a breakthrough in interactive experience. Users can control the rhythm of the light by repeatedly pressing the key, turning the fragmented time of waiting for the beverage to be cooked into a light interactive scene, breaking the boredom of mechanical waiting and making the operation process more participatory and interesting. Secondly, the dynamic effect of the light flashing can serve as an outlet for emotional release. When users are anxious or tired, they can relieve their stress in a concrete way by pressing the key and the change of light and shadow, strengthening the product's "emotional companionship" attribute, echoing the fun setting of "taking a break", and deepening emotional resonance. The feedback of the light flashing can clearly indicate the effectiveness of the key operation. At the same time, the dynamic light and shadow can serve as an informal status prompt (such as intermittent interactive signals during the cooking process), taking into account both practicality and entertainment.

[0017] (2) The handle is fixed to the top of the glass pot body by a hoop and screws. The hoop fits tightly into the pot body, and the screw connection ensures that the handle and the pot body are not loose. When the user picks up the glass pot body, the force is even, avoiding the pot body from slipping off and solving the safety hazard of "unstable hand-holding". The handle cover is also fixed to the outside of the handle by screws, which not only beautifies the appearance, but also enhances the structural strength of the handle and extends its service life.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved with", "connected", etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0024] This utility model provides, for example Figure 1-3 The illustrated health-preserving kettle with piano keys includes:

[0025] The base 1 is made of fine frosted PP, which provides a stable support frame for the entire health pot. At the same time, the interior is reserved for installation space to accommodate the electronic control components. The top of the base is adapted to support the glass pot body 2 made of high borosilicate material. The bottom of the glass pot body 2 is fixed with a heating plate 3 (thickness T0.4mm, material: titanium, parameters: 220V~50Hz-800W, with laser-engraved Ti mark). The heating plate 3 can receive electrical energy and convert it into heat energy. The heat is transferred to the glass pot body 2 through thermal conduction, thereby realizing the functions of heating, stewing or keeping warm the liquid in the pot.

[0026] The light piano key 4 (model: RD-RS-015, material: semi-transparent ABS polished) is located at the front end of the base 1. The light piano key 4 can be pressed continuously to make the light piano key 4 flash.

[0027] The hoop 5 (material: fine frosted PP) is fixedly fitted to the top outer side of the glass pot body 2 by screws 6 (material: zinc). It can fit tightly against the outer wall of the pot body to form a stable connection base and effectively distribute the force on the handle 7. The handle 7 is fixed to one side of the hoop 5 by screws. The handle 7 provides an ergonomic grip point for the user to pick up the glass pot body 2. Through the coordinated fixation of the hoop 5 and the screws 6, it is ensured that the handle 7 and the glass pot body 2 are not loose or displaced. This ensures that the force on the pot body is even when the user picks it up, and avoids the pot body from slipping or being damaged due to excessive local force, further improving the safety and convenience of use.

[0028] The top of the glass kettle body 2 is fitted with a lid 8 (material: fine frosted PP). The lid 8 is used to seal the top opening of the glass kettle body 2 to prevent steam from escaping and dust from falling in during heating. The bottom surface of the lid 8 is fitted with silicone 9, which can fit tightly with the top edge of the glass kettle body 2 when the lid 8 is closed, forming a sealing structure to prevent steam leakage and maintain a stable temperature inside the kettle. It also has a buffering and heat insulation function to prevent the lid 8 from being damaged by direct collision with the kettle body. The bottom of the lid 8 is fixed with an inner liner 10 by screws. The inner liner 10 is used to reinforce the installation stability of the silicone 9, prevent the silicone 9 from falling off or deforming after long-term use, and enhance the overall structural strength of the lid 8. The top of the lid 8 is connected to a handle 11 (material: fine frosted PP). The handle 11 is made of heat-insulating material, providing a convenient grip for users to open the lid 8 and avoiding burns caused by direct contact with the heated lid 8.

[0029] A teapot support 12 (material: fine frosted PP) connects the base 1 and the glass teapot body 2. The teapot support 12 serves two purposes: firstly, it supports the glass teapot body 2, ensuring its stability and coaxiality when placed; secondly, it provides heat insulation, preventing heat from the heating plate 3 at the bottom of the glass teapot body 2 from being transferred to the base 1, thus preventing burns to the user due to excessively high temperatures on the outer shell of the base 1. The teapot support 12 contains an upper coupler 13 (model: QX568E-R, material: 304, temperature control range: 115~126℃). The upper coupler 13 is screwed to the heating plate 3, enabling conductive connection between the heating plate 3 and external circuitry. When the teapot support 12 is placed on the base 1, the upper coupler 13 automatically and precisely aligns with the lower coupler 14 inside the base 1, ensuring stable current transmission to the heating plate 3 and providing a reliable conductive path for the heating function.

[0030] The base 1 is screwed with a lower coupler 14 (model: QX578E). The lower coupler 14 serves as an intermediate conductive component between the power supply and the heating plate 3. It can receive instructions from the main control component to control the circuit on and off. When a heating instruction is received, it can cooperate with the upper coupler 13 to form a conductive circuit to supply power to the heating plate 3. When heating is not needed or an abnormality occurs, the circuit can be cut off to ensure safe use. The base 1 is equipped with a computer board 15, and a speaker 22 is electrically connected to the computer board 15. The speaker 22 is mainly used to provide audio feedback to enhance the user's interactive experience with the health pot. The computer board 15 is the control center of the entire health pot. It can receive voice commands, button signals, and temperature sensor signals. After parsing the commands through the built-in program, it sends control commands to the heating plate 3, the light key 4, the display screen 18, and other execution components. It also has temperature monitoring and feedback functions. It can automatically adjust the heating power or cut off the heating according to the temperature of the liquid in the pot to ensure that the temperature is stable within the set range. In addition, it can also realize fault detection and protection to improve the stability and safety of the equipment operation.

[0031] The base 1 has several buttons 16 (material: polished PP, quantity: 3) inside its top. These buttons 16 serve as manual operation components, providing users with direct triggering methods for functions such as power on / off, mode switching, light piano key start / stop, and temperature adjustment. They can also be used as an auxiliary control method in situations where voice commands are not recognized, such as in noisy environments or emergency operation scenarios, ensuring uninterrupted operation. Springs 17 are fitted at the bottom of both buttons 16 and light piano keys 4. The two ends of the springs 17 fitted at the bottom of buttons 16 are connected to buttons 16 and the base 1, respectively, while the two ends of the springs 17 fitted at the bottom of light piano keys 4 are connected to light piano keys 4 and the base 1, respectively. Next, the spring 17 can generate elastic deformation when the button is pressed to provide pressing feedback. At the same time, after the pressing is finished, it drives the button 16 or the piano key control component to quickly reset, ensuring contact separation and avoiding functional abnormalities caused by continuous contact. The top of the base 1 is also equipped with a display screen 18 (material: black transparent PVC, size: 38.621.60.8, with adhesive backing). The display screen 18 can receive the device status information transmitted by the computer board 15 and intuitively display the current temperature, working mode, remaining time, etc. in the form of text, symbols or numbers, so that users can keep track of the device's operating status in real time and improve the intuitiveness of operation.

[0032] The bottom of the base 1 is fixed with a bottom cover 19 (material: PP fine frosted) by screws. The bottom cover 19 is used to close the bottom opening of the base 1, providing physical protection for the computer board 15, lower coupler 14 and other electronic control components inside the base 1, preventing dust and water stains from entering and causing short circuits or component damage, while also facilitating later disassembly and maintenance. A power cord 20 is provided on one side of the base 1. The power cord 20 can introduce external 220V AC mains power into the base 1 to provide working power for all electronic control components such as the computer board 15 and lower coupler 14. Its terminals are insulated to avoid the risk of leakage and ensure power supply safety.

[0033] The handle 7 is fixed with a handle cover 21 (material: ABS fine frosted) by screws. The handle cover 21 can cover the screw connection part of the handle 7, beautify the appearance of the product, and avoid the risk of scratches caused by exposed screws. On the other hand, it can enhance the structural strength of the handle 7, prevent the handle 7 from cracking or deforming after long-term use, and extend the service life of the handle 7. At the same time, its surface can be designed with anti-slip texture to further improve the stability when gripping.

[0034] This health-preserving kettle with piano keys has its internal wires electrically connected to the computer board inside the base 1 after the power cord 20 is connected to an external power source. The computer board, as the "control center", is connected to the voice receiving module, buttons, heating plate 3, piano keys 4, and display screen 18 through dedicated lines, forming a complete signal receiving and command sending link. When the signal of the user's operation button is received, the computer board will first perform preliminary identification of the signal. After confirming that the signal is valid, it will send precise control commands to the corresponding execution components. At the same time, it will transmit status information to the display screen 18 to ensure that the user can keep track of the product's working status in real time.

[0035] When the user issues a heating command via the heating button, the signal is quickly transmitted to the computer board 15 in the form of an electrical signal. After the computer board 15 analyzes the signal, it immediately sends a "power on" command to the lower coupler 13 in the base 1. The lower coupler 13 then enters the working state. Since the heating plate 3 at the bottom of the glass pot 2 is firmly connected to the upper coupler 14 in the pot holder by screws, and when the pot holder 12 is placed on the base 1, the upper coupler 13 and the lower coupler 14 will automatically align and fit together. The current can be smoothly transmitted to the heating plate 3 through the lower coupler 14. After the heating plate 3 is powered on, it quickly generates heat and transfers the heat to the bottom of the glass pot 2 through heat conduction. Then, the pot body evenly conducts the heat to the internal liquid to achieve the heating or stewing effect.

[0036] During the heating process, the control board 15 continuously receives temperature signals from the temperature sensor near the heating plate 3. If the liquid temperature reaches the user-set mode requirements (such as the temperature range corresponding to the "heat preservation mode"), the control board 15 will automatically send a "reduce power" or "power off" command to prevent the temperature from becoming too high. If the temperature is lower than the set value, heating will be restarted to ensure that the liquid temperature remains stable within the required range. At the same time, the display screen 18 receives the temperature and mode information transmitted by the control board in real time and presents it in clear symbols or text, allowing users to intuitively understand the heating progress.

[0037] When a user presses the button corresponding to the piano key 4 on the base 1, the signal is directly transmitted to the computer board 15. After confirming the command, the computer board 15 immediately connects the circuit containing the piano key 4, and the current is transmitted through the circuit to the light-emitting component (such as an LED) inside the piano key 4, causing the piano key 4 to emit a soft light. If the user needs to turn off the piano key 4, they only need to press the button repeatedly, and the computer board 15 will quickly cut off the circuit of the piano key 4, the light-emitting component will stop working, and the light will immediately turn off. The computer board 15 inside the base 1 acts as the control center. In addition to receiving voice commands, button signals, and temperature sensor signals, it also supports the function of setting custom voice content. Users can press and hold the base button to control key nodes of the device operation (such as adding water, etc.). The prompts for boiling and keeping warm are replaced with humorous homophones, such as setting "adding new water" as "getting a raise" and "the water is boiling" as "good fortune arrives". When the sensor detects the corresponding operation (such as the water level dropping to trigger a water-adding prompt or the temperature reaching the boiling point), the computer board 15 will call the preset voice library and play the set content through the built-in speaker 22. This design makes voice interaction go beyond the scope of simple function prompts. While ensuring clear operation guidance, it relieves daily stress with humorous expressions. When adding water, users hear the homophone blessing of "getting a raise", and when the tea boils, they receive the fun reminder of "good fortune arrives". This transforms the mechanical operation process into a relaxed emotional touchpoint, enhancing the user experience of "relieving stress while maintaining health".

[0038] Furthermore, the base 1, hoop 5, and handle 7 use a high-saturation blue, yellow, and red color scheme to replicate the vibrancy of Lego bricks, instantly brightening the desktop. This strong visual impact is like a declaration of emotion from young people—breaking the dullness with bright colors, integrating trendy memes and Lego fun into the health pot, making it a "life weapon" for young people to combat anxiety. It is hoped that every time it is used, it will be like hiding in a special "slacking-off corner," using fun design to dilute stress and make abstract emotions concrete. The words "slacking off" are set on the piano key 4. When the "slacking off" light on the piano key 4 is lit, the health pot becomes an "emotional stress relief tree hole."

[0039] like Figure 3 As shown, the computer board 15, model QT-RSD-002-V01 (functions include start / cancel, function, and timer / schedule buttons), is a main control board integrating power conversion, intelligent control, load driving, and status feedback. It is widely applicable to small household appliances such as electric kettles and rice cookers, or industrial control scenarios. Its working principle follows the core process of "power input → signal processing → control decision → execution feedback."

[0040] 1. Power Input and Conversion Module

[0041] Function: Converts 220V AC mains power to 5V / 3.3V DC power to power iFlytek C3101-L01C (pure offline voice chip), main control MCU, relays, etc.

[0042] Key components and signal flow:

[0043] AC-L / AC-N: When connected to 220V AC mains power, after overcurrent protection by F1 (fuse), it is converted into pulsating DC power by D3 (rectifier bridge).

[0044] D3 (rectifier bridge): Composed of 4 diodes, it converts alternating current into pulsating direct current.

[0045] EC1 (47μF / 400V electrolytic capacitor): filters pulsating DC current and outputs a stable DC voltage of approximately 310V (to power the subsequent high-voltage circuit).

[0046] L2 (500μH inductor) + secondary capacitor: further filtering to suppress voltage fluctuations (if it is a multi-output circuit, it will also generate a 5V / 3.3V low voltage through DC-DC conversion to power microcontrollers and other chips).

[0047] II. Main Control and Signal Processing Module

[0048] Function: Collect external inputs (temperature, button inputs) and generate control commands through microcontroller program logic.

[0049] Key components and signal flow:

[0050] Main control chip (IC1): The "brain" of the circuit board, usually a microcontroller (such as STM8S003, STM32), with built-in program responsible for:

[0051] Analyze input signals such as buttons and temperature signals;

[0052] Execute preset control logic (such as "stop heating at 100℃" or "keep warm for 60 minutes").

[0053] The output control signal drives the subsequent circuit.

[0054] Temperature detection:

[0055] NTC (Negative Temperature Coefficient Thermistor): The resistance decreases as the temperature rises. The microcontroller collects the voltage change through a sampling resistor (such as R6) and calculates the real-time temperature (such as the water temperature in a health pot).

[0056] XRM (210kΩ potentiometer): Calibrates temperature thresholds (e.g., setting the reference voltage for "brewing tea at 85℃" or "boiling at 100℃").

[0057] Key input: Through key nodes such as K1-K5, users can send commands such as "power on" and "mode switch". The microcontroller will detect the level change of the key pin and trigger the corresponding program.

[0058] III. Execution and Driver Module

[0059] Function: Drives high-power loads (such as heating elements) according to the master control instructions, and provides feedback on the working status through sound and light signals.

[0060] Key components and signal flow:

[0061] Relay drive:

[0062] K1-K5 (Relays): The small current signal output by the microcontroller cannot directly drive high-power loads such as heating tubes. The relays indirectly control the opening and closing of high-current circuits through "coil energization → contact closure" (e.g., when K1 is closed, the heating tube is energized and heated).

[0063] Diode (e.g., D): Connected in parallel across the relay coil to suppress the reverse electromotive force when power is off, protecting the microcontroller pins.

[0064] Status feedback:

[0065] BUZ (Speaker 22): Prompts operation via "short beep / long beep" (such as button confirmation, fault alarm).

[0066] LED1 (Indicator Light): Displays the working mode (such as "Heating", "Keep Warm" or "Fault") by "Still On / Blinking".

[0067] IV. Extension and Auxiliary Modules

[0068] Function: To expand the functionality of the device or ensure circuit stability.

[0069] OUT interface: can be connected to external water pumps, additional sensors and other devices (such as the "automatic water filling" function of a health pot, or external actuators in industrial scenarios).

[0070] SMG1 (Digital Tube / Display): If it is a digital tube, it can display information such as temperature and remaining time; if it is a display interface, it can be expanded to display graphical information.

[0071] Passive components (resistors, capacitors): used for voltage division, current limiting, filtering, and delay (such as for NTC voltage division sampling and microcontroller power supply filtering).

[0072] Workflow example (taking the "heating and keeping warm in a health pot" scenario as an example)

[0073] Power-on initialization: Connect to 220V AC power, F1 is normal, the rectifier and filter circuit outputs 310V DC voltage, and the microcontroller performs a self-test (LED1 flashes and BUZ beeps briefly).

[0074] User command input: Press the "Heat" button, the microcontroller detects the change in the button pin level and enters "Heat Mode".

[0075] Real-time temperature monitoring: The NTC continuously monitors the water temperature inside the kettle and converts the temperature signal into a voltage signal, which is then transmitted to the microcontroller.

[0076] Heating logic execution:

[0077] If the water temperature is <100℃: the microcontroller outputs a high level, causing the heating relay (such as K1) to activate, and the heating tube is powered on for heating;

[0078] If the water temperature is ≥100℃: the microcontroller outputs a low level, K1 is disconnected, heating stops, and the system switches to "heat preservation mode" (if heat preservation relay K2 is present, K2 will be activated at this time).

[0079] Status feedback:

[0080] During heating: LED1 remains constantly lit, and a short BUZ beep indicates "Heating in progress";

[0081] During heat preservation: LED1 flashes, BUZ is silent;

[0082] In case of malfunction (such as dry burning): the microcontroller detects an abnormality in the NTC resistor (such as the resistance value being too low), immediately cuts off all heating relays, the BUZ alarm sounds continuously, and LED1 flashes rapidly.

[0083] Core design features

[0084] Modular redundancy: The power supply, control, and drive modules are independent, making it easy to locate faults (e.g., when the F1 fuse blows, it only affects the power supply and does not damage the control circuit).

[0085] Electromagnetic compatibility (EMC) optimization: B1B1E (common-mode filter inductor) suppresses grid interference, and L2 (inductor) + capacitor filtering reduces power supply fluctuations.

[0086] Highly expandable: The OUT interface, SMG1 display screen, and K1-K5 relays reserve space for functional expansion, which can be adapted to different equipment needs.

[0087] 2. iFlytek C3101-L01C Voice Control Module

[0088] Function: Recognizes user voice commands (such as "heat" or "keep warm"), outputs control signals to drive relays, and provides status feedback through an audio interface.

[0089] Hardware connection and signal interaction:

[0090] Power supply: Connect VCC to 5V power supply and GND to ground, ensuring that the voltage level is consistent with that of the main control MCU.

[0091] Control signal output: The IO port of C3101-L01C (such as PA5) is directly connected to the control terminal of heating relay K1 to realize "voice command → IO high level → K1 energize → heating tube powered on".

[0092] Audio feedback: Connect the PWM audio output of C3101-L01C to BUZ (speaker 22) or speaker 22 to play preset voice messages such as "Start heating" and "Water has boiled".

[0093] Temperature control linkage: Communicates with the main control MCU through the UART interface to read the temperature data of the NTC (negative temperature coefficient thermistor) and realize "voice command + temperature closed-loop control" (such as "heat to 85℃").

[0094] 3. Main control MCU and signal processing module

[0095] Function: Collects temperature and key signals, and works with C3101-L01C to execute control logic.

[0096] Key components and interactions:

[0097] NTC: Detects the water temperature in the health pot. When the temperature rises, the resistance decreases. The main control MCU samples and calculates the real-time temperature through ADC and transmits it to C3101-L01C for voice feedback (such as "reached 85℃").

[0098] XRM (210kΩ potentiometer): calibrates the temperature threshold (such as setting the reference voltage for "100℃ boiling"). The C3101-L01C can read this threshold via UART to achieve precise temperature control.

[0099] 4. Execution and Driver Module

[0100] Function: Drive loads such as heating tubes and indicator lights according to instructions from C3101-L01C or the main control MCU.

[0101] Key components and logic:

[0102] K1-K5 (Relays): K1 is a heating relay. It is activated when the IO port of C3101-L01C outputs a high level, connecting the heating tube circuit. K2-K5 can be expanded to control functions such as heat preservation and water pump.

[0103] LED1: Status indicator light. The C3101-L01C controls its "always on / blinking" status via the IO port, corresponding to "heating in progress / keeping warm" and other statuses.

[0104] II. Workflow Example (Voice-Controlled Heating Scenario)

[0105] Voice command input: When the user says "Little pot, little pot, start heating", the microphone of the C3101-L01C picks up the voice and recognizes it as a "heating" command through an offline algorithm.

[0106] Control signal output: PA5 of C3101-L01C outputs a high level, triggering relay K1 to close, and 220V AC mains power is connected to the heating element through contact K1.

[0107] Real-time temperature monitoring: The NTC monitors the water temperature, and the main control MCU transmits the temperature data to the C3101-L01C via UART.

[0108] Voice feedback and closed-loop temperature control:

[0109] When the water temperature reaches 100℃, the main control MCU notifies C3101-L01C, which then plays the voice message "The water has boiled" and controls K1 to disconnect and stop heating.

[0110] If the user says "keep warm", the C3101-L01C controls K2 to engage, entering the keep warm mode, and LED1 flashes to indicate this.

[0111] 1. Purely offline voice interaction

[0112] It can directly recognize commands such as "heat" and "keep warm" without needing an internet connection, with a response time of less than 700ms, making it suitable for scenarios with unstable networks, such as kitchens.

[0113] 2. Anti-interference and stability design

[0114] Power supply filtering: A 0.1μF ceramic capacitor and a 10μF electrolytic capacitor are connected in parallel to the VCC terminal of the C3101-L01C to suppress ripple interference in the 220V circuit.

[0115] Physical isolation: The C3101-L01C is kept at a distance of more than 2cm from high-voltage circuits (such as AC-L / AC-N) to avoid electromagnetic interference that could cause voice recognition errors.

[0116] 3. Power safety redundancy

[0117] If the heating element power is greater than 500W, the IO port of C3101-L01C controls the main heating relay K1 through an intermediate relay (such as JQC-3FF) to prevent the chip from overcurrent.
