Description

Technical Field

[0001] This invention relates to the cross-technical field of voicebooks and children's intelligent interactive prize devices, specifically disclosing a multi-type prize linkage device based on voicebook signal drive and capable of linking with electric toys. This device integrates four core functions: voice signal acquisition and conversion, signal counting, differentiated quantitative output of prizes (solid granular snacks / liquid beverages), and 11 sound, light, and motion linkage feedback from electric toys. It is specifically adapted to learning incentive scenarios (such as voicebook quiz rewards and knowledge point learning feedback) and play interaction scenarios (such as two-player competition rewards) for children aged 3-12. Through a collaborative mechanism of "prize output + multi-dimensional feedback from toys," it constructs a closed-loop incentive system of "learning behavior - instant reward," filling the application gap of existing children's interactive devices in the "voice learning - multi-type prize linkage" scenario. Background Technology

[0002] Currently, products related to children's voice learning and reward output on the market are mainly divided into two categories, but both have significant technical defects and cannot meet children's integrated needs for "voice learning - multiple types of rewards - fun interaction":

[0003] I. Defects in Microfluidic Control Products

[0004] Taking the "Portable Miniature Water Pump" with publication number CN202320123456.7 as an example, this type of product only realizes the single function of "pumping water when powered on and stopping pumping when powered off", and has three shortcomings:

[0005] 1. Lack of voice interaction capability: It does not integrate a voice signal acquisition and counting module, cannot respond to the knowledge point output signals of the audio book, and cannot be associated with learning behavior;

[0006] 2. Lack of engaging feedback design: It lacks the linkage structure of electric toys, can only output liquid, and has no interactive feedback such as light, sound, or movement, so it cannot form a "learning-reward" incentive loop;

[0007] 3. Limited prize types: Only compatible with liquid output, unable to meet the needs of common children's reward scenarios such as solid granular snacks (such as popcorn and candy).

[0008] II. Defects of Voice Books and Existing Prize Machines

[0009] The existing voice book 1 (hereinafter referred to as 1 / 1-1 / 1-2 collectively) only has a one-way knowledge output function and does not have a reward mechanism linked to learning progress and answer results. There is currently no dedicated reward machine on the market for "voice book 1 signal-driven" for children's voice learning scenarios, and there are no multi-type reward devices that simultaneously adapt to solid / liquid rewards and single / double-user scenarios. If the existing product combination (voice sensor + independent counter + toy controller + micro pump / motor) is used to achieve "voice triggering - counting - reward output - toy linkage," four major problems will arise:

[0010] 1. Large size: The overall volume after assembly is about 3 times that of the device of this invention, making it unsuitable for small spaces such as homes and early education institutions;

[0011] 2. High cost: The combined cost is approximately 2.5 times that of this invention, which is not conducive to large-scale promotion;

[0012] 3. Poor compatibility: The communication protocols and power supply standards of various devices are not uniform, which can easily lead to problems such as signal interruption and false triggering;

[0013] 4. Safety hazards: The external wiring is complex and lacks child-safe protection, posing risks of short circuits and electric shock, and cannot be operated independently by children.

[0014] The root cause of the above defects is that the technical concept of existing products is limited to "single-function tools" and does not deeply integrate "the incentive needs of children's voice learning" with "multi-type prize output + fun linkage with toys". It lacks an integrated design of "voice acquisition - counting - multi-type prize output - 11 linkage with electric toys", and cannot meet the technical requirements of children's learning scenarios for "functional integration, scenario diversification, ease of operation and safe use".

[0015] Addressing the shortcomings of existing products, the core innovations of this invention are: ① Designing an integrated control circuit board 14 for 'voice acquisition-counting-driving-toy linkage', integrating dispersed voice sensors, counters, and driving modules onto a single PCB, solving compatibility and size issues; ② Proposing a 'general-purpose component + form-differentiated component' architecture, enabling the output of multiple types of prizes by changing devices, solving the problem of limited prize types in existing products; ③ Introducing a dual-delay circuit (AB delay) in collaboration with the L293D driving chip to achieve synchronous linkage between the actuator and the toy, solving the problem of lack of engaging feedback in existing products, clearly distinguishing it from existing technologies. Summary of the Invention

[0016] Purpose of the invention

[0017] To address the technical shortcomings of existing products, such as "limited functionality, lack of voice interaction, compatibility with only a single prize type, lack of toy integration, and low integration," the specific objectives of this invention are as follows:

[0018] 1. A multi-type prize linkage device based on voice book 1 signal drive and can be linked with electric toy 11 is provided. It integrates the full process function of "voice signal acquisition and conversion - signal counting - quantitative output of multiple types of prizes - linkage feedback of electric toy 11", realizes the automated operation of "voice book 1 signal triggering → automatic counting → delayed prize distribution → toy interactive feedback → reset standby", without the need for any additional external devices.

[0019] 2. Based on a unified technical architecture, three parallel sub-devices are designed: a solid granule snack prize machine, a single-person beverage prize machine, and a double-person beverage prize machine, covering both solid and liquid prize forms and two usage scenarios: single-person learning and double-person competition. Moreover, the three types can be quickly converted by changing the external connection cable (plug-and-play terminal cable), improving the versatility of the device.

[0020] 3. Ensure the device meets safety and child-friendly standards: all parts in contact with the prizes are made of food-grade materials; the circuit module has dual protection against overload and charge / discharge; the electric toy 11 is equipped with a spring buffer structure (jump amplitude ≤3cm); at the same time, it is designed with a cartoonish appearance and sound and light feedback, taking into account both functionality and children's user experience.

[0021] Technical solution

[0022] This invention is based on a unified technical concept of "voice acquisition - counting control - multi-component linkage - differentiated prize output," and proposes three parallel sub-devices: a solid granule snack prize machine, a single-person beverage prize machine, and a double-person beverage prize machine.

[0060] 2. Unified circuit structure and signal link

[0061] The three sub-devices have completely identical circuit logic, all following a closed-loop process of "signal input → processing → counting → triggering → execution → reset". Only the actions of the executing components match their respective structural forms.

[0062] ①Signal Input and Conversion: Voice Book 1 outputs knowledge point voice → rubber sleeve focuses signal → microphone converts to analog electrical signal → microphone line transmits to signal input terminal block 26 of control circuit board 14;

[0063] ②Signal processing and counting: The sound sensor module amplifies and generates a switching electrical signal → transmits it to the counting module for accumulation → the digital tube 3 displays the count (00-99) in real time;

[0064] ③ Threshold triggering and driving: When the count reaches the preset threshold, the counting module outputs a trigger signal, the motor drive module starts, and synchronously sends drive signals to the actuator and the electric toy 11; the delay circuit module starts to maintain the drive state;

[0065] ④ Prize distribution and linkage:

[0066] - Solid granule type: The central motor drives the rotating plate 18 to push the snack → the front motor drives the connecting rod 16 to open the valve 15 → the snack falls into the prize receiving container 4; the electric toy 11 synchronizes sound and light + jumping;

[0067] - Beverage type: Water pump operates → Beverage flows through inlet pipe → water pump → outlet bend pipe → liquid outlet nozzle into cup; Electric toy 11 synchronized sound and light + jumping.

[0068] ⑤ Reset standby: Delay ends → Delay circuit module stops output → Execution unit and electric toy 11 stop (solid particle type front motor reverses to close valve 15) → Counting module clears to zero → Digital tube 3 displays "00" → Device standsby.

[0069] 3. General Design Standards

[0070] -Safety design: All parts in contact with the prize are made of food-grade materials; the circuit has lithium battery charge and discharge protection and motor drive module overload protection; the combination lock prevents children from accidentally opening the container; the electric toy's jump range is ≤3cm.

[0072] - Operation design: All external operating elements protrude to the outside, making it easy for children to operate independently; the whole process is automated, and can be triggered simply by "starting the device and using the voice book".

[0073] II. Differentiated technical solutions for three parallel sub-devices

[0074] 1. Sub-device 1: Solid Particle Snack Prize Machine Device

[0076] -Internal core component layout: The base 10 is divided into sections to fix dual DC30 micro geared motors 17-1 / 17-2 (5V, 150rpm, 0.8kg·cm), control circuit board 14 (PCB board size <15cm×3cm, integrating KY-037 sound sensor, TP4056 power management, CD4518 counting and other modules), 18650 lithium battery 13 (2000mAh, 5V, with charge and discharge protection); the central motor shaft extends to the upper container, and the end is connected to the ABS rotating plate 18; the front motor shaft is connected to the Z-shaped stainless steel connecting rod 16 and the ABS valve 15.

[0077] - Signal and counting link: Voice book 1 (60-80dB) → Rubber sleeve focus → Microphone converts to analog electrical signal → Shielded wire transmits to control circuit board → Sound sensor amplifies 100 times (outputs 3V switch signal when 1.5V threshold is reached) → Counting module accumulates count (digital tube displays 00-99) → Reaching preset threshold (default 10 times) → Trigger motor drive module → Link prize output and electric toy 11 → Count is reset to zero after output.

[0078] - Prize output drive process: Count reaches target → Central motor rotates forward to push snacks, front motor rotates forward to open valve (downward 1cm) → Snacks fall into receiving container (5-10g per time) → 10-second delay (adjustable 5-30 seconds) → Front motor rotates reverse to close valve, central motor stops → Reset and standby.

[0079] - Electric toy linkage design: The control circuit board is equipped with a PH2.0-2P electric toy terminal block 27 (side wall of base 10). After the toy is connected, the sound and light (red / blue LED flashing alternately at 0.5-second intervals; speaker ≤65dB) and jumping (≤3cm) are activated synchronously with the prize output, and the toy stops synchronously after the delay.

[0080] 2. Sub-device two: Single-person beverage prize machine device

[0081] - Overall structure composition: The core is a transparent food-grade PET hollow cylindrical main unit 20 (height < 22cm, diameter 10cm, wall thickness 2mm), with a lid 22 on top with a 3-digit combination lock 3 (with silicone cartoon characters attached); inside, one side is fixed with an ABS component box 24 (12cm×8cm×5cm), and the other side is equipped with a food-grade PET beverage container 21 (500ml, with a threaded sealing cap and O-ring).

[0082] -Internal core component layout: The component box 24 houses a DC50E miniature water pump (5V, 1.5L / min, 1.5m head), a control circuit board 14 (integrating a KY-037 sound sensor, TP4056 power management, L298N driver, and other modules), and an 18650 lithium battery 13 (2000mAh, 5V); the water pump inlet pipe extends to the bottom of the container (1cm from the bottom, sealed with an O-ring), and the water outlet bend passes through the main unit 20 to the outside, with a silicone outlet nozzle (5mm inner diameter) at the end; the component box has a green cleaning button 19 (facing the container).

[0083] - Signal and counting link: Same as solid particle type, voice book 1 signal → microphone → shielded wire → control circuit board → sound sensor amplification → counting module accumulation (digital tube displays 00-99) → reaching threshold (default 10 times) → triggering water pump and electric toy 11 linkage → output and count is cleared.

[0084] - Beverage dispensing and pipeline cleaning process:

[0085] - Beverage output: Count reaches target → Pump starts → 200ml beverage is output to cup within 10 seconds → Pump stops after delay;

[0086] - Pipeline cleaning: Press cleaning button 19 → motor drive module → drive water pump → draw clean water / disinfectant to flush pipeline → release button to stop pump.

[0087] - External operation and linkage with electric toy: The operating elements (digital tube 3, power switch 5, charging socket 25, etc.) protrude from the side wall of the main unit 20; after the electric toy 11 is connected to the terminal block, it will synchronize with the beverage output sound and light (LED flashing, speaker ≤65dB) and jump (≤3cm), and stop synchronously after a delay.

[0088] 3. Sub-device three: Two-person beverage prize machine device

[0089] - Overall structure composition: Transparent food-grade PET hollow cylindrical main unit 20 (height 22cm, diameter 15cm, wall thickness 2mm), top with a sealing cover with a 3-digit digital combination lock 8 (silicone sealing ring, sealing pressure 0.2MPa); two ABS component boxes 24 (12cm×8cm×5cm) are symmetrically arranged on both sides inside, and a food-grade PET shared beverage container 21 (1000ml, with a threaded cap and two water outlets at the bottom) is arranged in the center.

[0090] -Internal core component layout: Each side component box is fixed with one DC50E water pump, one control circuit board 14 (integrating KY-037 sound sensor, TP4056 power management, L293D driver and other modules), and one 18650 lithium battery 13 (2000mAh, 5V); the water inlet pipe of each side pump extends to the bottom of the container (1cm from the bottom, double sealed), and the water outlet bend passes through the corresponding side main unit 20 to the outside, with a 10cm distance between the liquid outlets on both sides; each side is equipped with an independent cleaning button 19 (facing the container side).

[0091] - Dual-sided independent signal and counting link: Independent signal acquisition on both sides, voice book 1 → microphone → shielded wire → same-side control circuit board → sound sensor amplification → same-side counting module accumulation (digital tube independently displays 00-99) → single side reaches threshold (default 10 times) → only triggers the same-side water pump and electric toy 11 → after output, the same-side count is cleared to zero, without affecting the other side.

[0092] - Dual-sided independent beverage output process: Single-sided counting reaches the target → same-side water pump starts → 200ml beverage is output within 10 seconds → pump stops after delay; both sides can output simultaneously or sequentially without interference; the cleaning process is the same as the single-person model, and the single-side button only controls the same-side water pump.

[0093] -Dual-sided independent operation and linkage with electric toys: The operating elements (digital tube 3, power switch 5, etc.) on both sides protrude symmetrically from the side wall of the main unit 20 and operate independently; when a single side is triggered, only the electric toy 11 on the same side will start the sound and light and jump (≤3cm), and stop synchronously after a delay.

[0094] III. Core Working Logic (Common to all three sub-devices)

[0095] 1. Standby mode: Press the power switch, the device is ready, and the digital tube displays "00";

[0096] 2. Signal Triggering and Processing: Voicebook 1 output signal → rubber sleeve focuses → microphone converts to analog electrical signal → shielded wire transmits to control circuit board → sound sensor amplifies 100 times (reaching 1.5V threshold to output 3V switching signal) → NE555 multivibrator shapes into 1Hz pulse;

[0097] 3. Counting and display: A 1Hz pulse is transmitted to the CD4518 counting chip → count accumulation (00-99) → CD4511 decoding → real-time display on the digital tube 3;

[0098] 4. Threshold trigger: When the count reaches the preset value, CD4518 outputs a high level, triggering the L293D driver module;

[0099] 5. Linked execution and delay: The drive module outputs 5V to the actuator and electric toy 11, and simultaneously powers the NE555 delay module → the delay module maintains the drive state;

[0100] 6. Driver execution:

[0101] - Solid granule type: The central motor pushes the snack, and the front motor opens the valve → the snack falls; the toy has sound and light effects + jumping (≤3cm, LED flashing, horn ≤65dB);

[0102] - Beverage type: Water pump starts → 200ml beverage output in 10 seconds; Toy synchronized with sound and light + jumping;

[0103] 7. Reset Standby: 10-second delay ends → delay module level flips → drive module stops → actuator and toy stop (solid particle type valve closes) → CD4518 clears → digital tube displays "00" → standby.

[0104] This invention provides a prize machine device based on voice signal driving and linkage with electric toys. The device is divided into general components and form-differentiated components. The general components include signal acquisition and conversion components, control modules, and auxiliary components. The form-differentiated components include solid particle type sub-devices, single-person beverage type sub-devices, and double-person beverage type sub-devices. The control logic, power link, and signal link of the solid particle type sub-device, single-person beverage type sub-device, and double-person beverage type sub-device are consistent. The device type can be switched by plugging and unplugging terminal wires to replace the host component and the execution component.

[0105] The signal acquisition and conversion components include a voicebook, a soft rubber sleeve, a microphone, and shielded electronic wires. The voicebook outputs a voice signal, which is focused by the soft rubber sleeve and converted into an analog electrical signal by the microphone. The shielded electronic wires then transmit the analog electrical signal to the control module. The control module is a control circuit board, which integrates an electrically connected sound sensor module, a power management module, a counting module, a delay circuit module, and a motor drive module. The counting module includes a BCD counter, and the delay circuit module uses a monostable circuit. The circuit board is equipped with a digital display, a power switch, a charging socket, a signal input terminal block, and a linkage terminal block for connecting external electric toys. Some wiring harnesses and connectors pass through the housing to achieve external connections.

[0106] The auxiliary components include a lithium battery and an electric toy. The lithium battery powers the entire device, and the electric toy is connected to the linkage terminal block, enabling synchronized movement with the actuators to achieve sound, light, and jumping linkage feedback. The entire device's execution signal chain is as follows: the voice signal is acquired, converted, and sent to the control circuit board, where the counting module accumulates the count; when the count reaches a preset threshold, the motor drive module drives the corresponding actuator to output the prize, simultaneously activating the electric toy; after the delay, the actuator stops, the counting module is reset to zero, and the device resets to standby mode.

[0107] The solid particle sub-device adopts a split structure with an upper prize container and a lower base. The base is equipped with two DC30 micro geared motors. The shaft of one micro geared motor extends into the prize container, and the end of the shaft is equipped with an ABS rotating plate. The other micro geared motor drives the valve through a Z-shaped connecting rod to realize the opening and closing control of the prize outlet.

[0108] The single-person and double-person beverage-type sub-devices employ a nested structure consisting of an outer main unit housing, an inner container, and an ABS component box. The single-person sub-device features a single component box, a single water pump, and an independent beverage container. The double-person sub-device features two symmetrical component boxes, two water pumps, and a shared inner container, with each side capable of independently performing signal acquisition, counting, and beverage output. The sub-devices also include a cleaning button for manual control of the water pumps to flush the pipeline. All components in direct contact with the prize, including the container, pipelines, and receiving components, are made of food-grade materials, and the circuitry features charge / discharge and overload protection.

[0109] Beneficial effects

[0110] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0111] 1. Functional Integration Innovation: For the first time, it integrates four major functions: "voice signal acquisition and conversion, signal counting, multi-type prize output, and electric toy linkage" into one, solving the shortcomings of existing products that are "single-function and lack voice interaction". The entire process is automated, requiring no external equipment, and is compact in size (the single-person host unit measures 25cm×15cm×12cm, which is only 1 / 3 the size of existing combined products).

[0112] 2. Strong scene adaptability: The three parallel sub-devices cover solid / liquid prizes and single / double scenarios—solid granules are suitable for snack rewards, single-person beverages are suitable for individual learning, and double-person beverages are suitable for competition interaction; and the three types can be quickly switched by changing the component box 24, which is highly versatile.

[0113] 3. Child-friendly design:

[0114] - Safety Protection: All contact parts of the prize are made of food-grade materials (PET / PP); the circuit module has double protection (lithium battery 13 charge and discharge protection, L293D drive module overload protection); the electric toy 11 spring has a plastic limit sleeve (2cm in length) to prevent pinching fingers; the combination lock prevents children from accidentally opening the container;

[0115] - Experience optimization: The cartoonish appearance and sound and light motion feedback are in line with children's aesthetics; the operation only requires one step of "turning on the power switch 5", and the digital tube 3 displays the count intuitively. No complicated settings are required, making it suitable for children to use independently.

[0116] 4. High technical feasibility: The core components (CD4518 chip, NE555 chip, micro motor / water pump, etc.) are all market-standardized products with low procurement costs (single-person unit cost ≤ 100 yuan); the circuit connection follows general specifications, and the modular design facilitates mass production and maintenance (the component box is detachable, and the core components are connected through terminal wires, so only the corresponding module needs to be replaced during maintenance).

[0117] 5. Significant incentive effect: Through the closed-loop design of "voice learning - counting accumulation - prize output - toy interaction", abstract learning behavior is transformed into concrete reward feedback, which effectively enhances children's initiative and interest in learning.

[0183] Component designation explanation

[0184] In this manual, components with identical functions, shapes, and models, differing only in usage scenarios or installation locations (such as power switches 5 / 5-1 / 5-2, water outlet bends 23 / 23-1 / 23-2, etc.), are labeled using "main designation + sub-designation." The main designation (e.g., 5, 23) can uniformly refer to the corresponding sub-component. This labeling method does not affect the integrity of the component's core technical features and technical solution. Additionally, when describing a solid granular snack prize machine, it is sometimes simply referred to as a granular prize machine; however, it refers to the same device. Detailed Implementation

[0185] Referring to Figure 9, and based on the unified technical concept of "voice acquisition - counting control - multi-component linkage - differentiated prize output" of this invention, the specific implementation methods of the three parallel sub-devices—the solid granule snack prize machine device, the single-person beverage prize machine device, and the double-person beverage prize machine device—are described in detail below.

[0186] I. Overall Implementation Architecture (General for all three sub-devices)

[0187] The core components of the three sub-devices of this invention are all divided into "general components" and "morphology-differentiated components." Their circuit structures, signal links, and design standards are completely identical; the only difference lies in the host structure and the configuration of the execution components to accommodate different prize shapes. The specific implementation basis is as follows:

[0188] 1. Specific implementation of general components

[0189] The common component is shared by the three sub-devices. The selection, installation method, and functional implementation logic of each component are unified. The specific implementation details are as follows:

[0190] (1) Signal acquisition and conversion components

[0191] - Audiobook 1: Select audiobooks for children's early learning (such as pinyin, math knowledge points), and strictly control the speaker output sound decibels to 60-80dB (measured and calibrated by a decibel meter) to ensure that they are suitable for children's auditory perception and meet the microphone recognition threshold; the speaker sound outlet should be cleaned and then a soft rubber sleeve should be pasted on it, with the standard that "the rubber sleeve completely covers the speaker outlet" to avoid signal leakage.

[0192] - Soft rubber sleeve: Made of food-grade silicone with a Shore hardness of 30° (compliant with GB 4806.11-2021 standard), with 2mm diameter air holes inside (running through the upper and lower surfaces along the axis of the rubber sleeve), ensuring focused sound signal and providing space for microphone installation; the rubber sleeve is attached to the speaker outlet of the voicebook using double-sided tape (0.5mm thick, ≥5N / 25mm adhesion), and left to stand for 24 hours after attachment to ensure firmness and prevent it from falling off during use.

[0193] - Microphone: Select electret microphone (model WM-61A), sensitivity -42dB~-38dB, working voltage 3V~5V, directly embedded in the reserved groove inside the rubber sleeve (groove diameter is the same as the outer diameter of the microphone, depth 2mm), to ensure that the microphone pickup surface is accurately aligned with the speaker outlet of the voicebook (deviation ≤0.5m), avoiding signal acquisition deviation.

[0194] - Shielded electronic wire: Use AWG24 specification single-core shielded wire (conductor material is tinned copper, shielding layer is aluminum foil + braided mesh). Solder the microphone pins at one end with a soldering iron (soldering point length ≥1mm, solder point is coated with insulating varnish to prevent short circuit), and crimp the other end to PH2.0-2P terminal head (terminal head crimping force ≥80N to ensure firm contact); when wiring, avoid running parallel to other high-voltage lines to prevent electromagnetic interference from causing signal distortion.

[0195] (2). Control module

[0196] The core component is the control circuit board 14, which uses an FR-4 material PCB board (size ≤15cm×3cm, thickness 1.6mm). All components on the board are soldered using surface mount technology (SMT). Specific implementation details are as follows:

[0197] ①. Functional modules:

[0198] - Sound sensor module: Utilizes the KY-037 module, detecting frequencies from 20Hz to 16kHz. The module output is through a 0.1mm... 2 When connecting the electronic wire to the input terminal of the counting module, a 1kΩ current-limiting resistor needs to be connected in series between the module and the counting module to prevent excessive current from damaging the chip.

[0199] - Power management module: The TP4056 charging management chip is used, with an input voltage of 5V and an output current of 1A. The chip pins are connected to the lithium battery terminal block, the charging socket, and the main power line of the control circuit board, respectively. A 10μF tantalum capacitor (for filtering) is configured around the chip to ensure stable power supply.

[0200] -Counting module: Composed of CD4518 dual BCD synchronous adder counter, CD4511 BCD seven-segment latch / decoder / driver and NE555 multivibrator; the CLK terminal of the CD4518 chip is connected to the output terminal of the sound sensor module, the CO terminal (carry output terminal) is connected to the input terminal of the motor drive module, and the Q0-Q3 terminals are connected to the corresponding pins of the CD4511 chip; the NE555 chip is equipped with a 10kΩ resistor and a 100μF capacitor to form a 1Hz multivibrator circuit to provide clock pulses for the CD4518.

[0201] - Delay circuit module: It is equipped with dual AB delay circuit modules, both of which use NE555 chips to build monostable delay circuits. By adjusting the external 10kΩ adjustable resistor, the delay can be adjusted from 5 to 30 seconds (default setting is 10 seconds).

[0202] - Motor drive module: The motor drive module uses the L293D four-channel half-bridge driver chip. Its four signal input terminals (IN1~IN4) have clearly defined pin numbers, corresponding motors, and functions, as detailed below:

[0203] a. IN1 pin (pin 2 of the chip): Defined as the positive control input terminal for motor A, it only receives high-level signals from the A delay circuit module. When IN1 is high, the L293D chip's OUT1 pin (pin 1) outputs drive current, driving motor A (rotating plate drive motor) to rotate forward, causing the rotating plate inside the snack container to rotate clockwise, pushing the solid granular snacks towards the output port; when IN1 is low, motor A stops rotating forward.

[0204] b. IN2 pin (pin 7 of the chip): Defined as the reverse control input terminal of motor A. No control signal is connected in this circuit (because the snack delivery can be achieved by reversing motor A in both directions, so there is no need for reverse action). It is kept at low level by default. Only when the equipment is under maintenance or the snack is stuck can it be connected to a high level through an external debugging switch to drive motor A to run in reverse to clear the jam. Under normal circumstances, it does not participate in the regular working process.

[0205] c. IN3 pin (pin 10 of the chip): Defined as the positive control input of motor B, directly connected to the output of the delay circuit module A. When IN3 is high, the L293D chip's OUT3 pin (pin 11) outputs drive current, driving motor B (valve drive motor) to rotate forward, causing the valve connecting rod to rotate clockwise, opening the valve at the snack output port upward and opening the snack output channel; when IN3 is low, motor B stops rotating forward, and the valve remains in the currently open state.

[0206] d. IN4 pin (pin 15 of the chip): Defined as the reverse control input for motor B, it only receives a high-level signal from the B delay circuit module. When IN4 is high, the L293D chip's OUT4 pin (pin 14) outputs a drive current, driving motor B to rotate in reverse, causing the valve connecting rod to rotate counterclockwise, closing the valve downwards and blocking the snack output channel; when IN4 is low, motor B stops rotating in reverse, and valve 15 remains closed.

[0207] Note: IN1 and IN2 of the L293D chip are a set of complementary control terminals (corresponding to motor A), and IN3 and IN4 are another set of complementary control terminals (corresponding to motor B). Under normal conditions, only one pin of each control terminal is at a high level (to avoid conflict between the forward and reverse signals of the motor), and the chip enable terminals (pins 1 and 9) are both connected to a high level to ensure that the drive module is in the enabled state throughout the process.

[0208] ②. Operating and display elements:

[0209] - Digital tube 3: Select a 1.2-inch common cathode red seven-segment digital tube 3 (model SM410564). The pins are connected to the control circuit board 14 through 2.54mm pitch pin headers. When the digital tube 3 protrudes outward, a waterproof sealing ring (silicone material, 1mm thickness) needs to be pasted at the mounting hole to prevent dust from entering the interior.

[0210] - Power switch 5: Employs a lockable tactile switch (model TS-1185, with lock), 6mm in diameter, 0.5mm travel, and 0.5mm through-hole pins. 2 Connect the electronic wire to the output terminal of the power management module. Press the power button once to turn on and press it again to turn off to avoid accidental power-off.

[0211] - Charging female connector 25: Select DC-005 specification female connector (with dust plug), the pins are soldered to the charging input terminal of the power management module. When the female connector protrudes outside, it must be sealed with the main unit housing (gap ≤0.1mm) to prevent liquid from seeping in.

[0212] - Signal input terminal block 26: adopts PH2.0-2P terminal block, soldered to the input end of the sound sensor module. The insertion and extraction force of the terminal block is ≥3N to ensure that the shielded electronic wire is firmly connected. The beverage type sub-device additionally integrates a cleaning button 19 (model TS-016), which adopts a green touch button and is directly connected to the power supply end of the water pump through a wire. The button protrudes from the component box 24 towards the container side (protrusion height ≤2mm) to avoid accidental external touch.

[0213] ③. Linkage and auxiliary interfaces:

[0214] -2Pin linkage terminal block: Solid granule type is set on the side wall of base 10 (5cm from the bottom of base 10), and beverage type is set on the outside of component box 24 (2cm from the top of component box). Both adopt PH2.0-2P specification. The terminal block is fixed by screw (screw specification M2) to ensure that it does not loosen during use.

[0215] - Other terminal blocks: Lithium battery terminal block 29 adopts XH2.54-2P specification, motor / water pump terminal block adopts PH2.0-2P specification, and the spacing between all terminal blocks is ≥5mm to prevent short circuits during wiring.

[0216] (3) Auxiliary components

[0217] - Lithium Battery 13: Selects 18650 cylindrical lithium battery 13 (capacity 2000mAh, nominal voltage 5V), with built-in charge and discharge protection board (overcharge protection voltage 5.2V±0.1V, over-discharge protection voltage 3.0V±0.1V, short circuit protection response time ≤10ms); fixed by ABS plastic bracket (bracket thickness 2mm), with a 3mm thick sponge pad pasted between the bracket and the lithium battery to buffer the impact of vibration on the battery.

[0218] - Electric Toy 11: Selects cartoon-shaped toys (such as dog or car shapes), with integrated red / blue LED beads (working voltage 5V, current 20mA), miniature speaker (decibel ≤65dB) and eccentric wheel jumping motor (speed 3000rpm); the toy connects to the linkage terminal block of the control module via a PH2.0-2P plug, and the jumping amplitude is controlled by adjusting the weight of the eccentric wheel (weight ≤5g) to ensure that the jumping amplitude is ≤3cm, avoiding injury to children during use.

[0219] 2. Specific implementation of morphologically differentiated components

[0220] The core difference between the "solid granule type" and "beverage type" classifications lies in the host structure and execution components. Specific implementation details are as follows:

[0221] (1). Host Components

[0222] ①. Category 1: Solid granular type (split structure)

[0223] - Upper prize container 7: Made of food-grade transparent PET material (compliant with GB 4806.7-2016 standard), it is made into a cartoon gourd shape (height 20cm, maximum diameter 8cm, wall thickness 2mm) through injection molding process; the top of the container has a circular opening with a diameter of 5cm, and the edge of the opening is provided with a buckle groove (depth 2mm, width 3mm) for installing the container lid 9 with a combination lock 8.

[0224] - Container lid 9: Made of ABS material, the lid edge is equipped with a buckle that matches the container buckle groove (insertion depth ≥5mm, pull-out force ≥10N). The lock body is a 3-digit combination lock 8 (model ML-102). The buckle is fixed to the inside of the container lid 9 with screws (screw specification M1.6). The combination lock unlocking force is ≤5N, which is convenient for adults to operate and prevents children from opening it by accident.

[0225] -Lower base 10: Made of ABS material (wall thickness 2mm, impact strength ≥20kJ / m²) 2 The base is injection molded into a circular base (8cm in diameter and 10cm in height). Inside the base 10, there is a motor mounting slot (size matching a DC30 motor, tolerance ±0.1mm), a circuit board fixing boss (3mm in height, 4 in number), and a lithium battery bracket (18mm in inner diameter, compatible with 18650 lithium batteries 13). The front of the base 10 has through holes (diameters compatible with digital tube 3, power switch 5, and charging socket 25 respectively). The front is fixed with a food-grade PP material prize receiving container 4 (capacity 150ml, diameter 6cm, alignment accuracy with container output port 6 ≤2mm) to ensure that snacks do not spill.

[0226] - Dust cover: Made of ABS material (1.5mm thick), it is fixed to the bottom of the base 10 with 4 M3 stainless steel screws. A 3mm thick sponge cushioning pad (made of high-density sponge) is pasted on the inside of the dust cover to prevent the internal components of the base 10 from vibrating and making abnormal noises.

[0227] ②. Category 2: Beverage type (nested structure)

[0228] -Outer Main Unit 20 Shell: Made of ABS material (2mm wall thickness), it is injection molded into a transparent hollow cylinder (single-person type, height 22cm, diameter 10cm; double-person type, height 22cm, diameter 15cm); through holes are opened on the outside of the shell (to accommodate digital tube 3, power switch 5, charging socket 25, and water outlet bend 23 respectively), and the side is reserved with mounting positions for component boxes 24 (1 for single-person type and 2 for double-person type, symmetrically distributed, with a mounting depth of 5mm to ensure that the component boxes 24 do not protrude from the shell after being fixed); a circular groove (7cm in diameter and 2cm in depth) is opened at the front of the shell, and a silicone anti-slip pad (1mm thick) is pasted in the groove for placing a cup to receive beverages to prevent slippage.

[0229] -Inner beverage container 21: Made of food-grade transparent PET material (compliant with GB 4806.7-2016 standard). The single-person type is an independent bottle (capacity 500ml, bottle mouth thread specification M24×1.5), and the double-person type is a shared bottle (capacity 1000ml, bottle mouth thread specification M30×1.5, with 2 independent water outlets at the bottom, with an inner diameter of 8mm). The container mouth is equipped with a threaded sealing cap, with an O-ring silicone sealing ring (specifications 24×1.5mm and 30×1.5mm respectively) nested inside the cap. The sealing pressure is ≥0.2MPa to prevent liquid leakage.

[0230] - Built-in component box 24: Made of ABS material (single-person size 12cm×8cm×5cm, double-person size same specifications), it is fixed to the inside of the outer shell by buckles (buckle insertion depth ≥3mm, pull-out force ≥5N); the inside of the component box 24 is divided into 3 areas - the bottom is the water pump 30 installation area (with reserved buckles, adapted to DC50E water pump), the middle is the control circuit board 14 installation area (with 4 fixing holes, adapted to circuit board screws), and the top is the lithium battery 13 installation area (equipped with a plastic bracket to fix the lithium battery 13); the component box 24 has a button hole (diameter 6mm, adapted to cleaning button 19) on the side facing the beverage container 21, and a terminal block hole (adapted to linkage terminal block) on the outside.

[0231] (2). Execution component

[0232] ①. Category A: Solid Particle Type (Dual Miniature Gear Motor 17, where 17-1 / 17-2 can be collectively referred to as 17)

[0233] - Motor selection: The DC30 model micro geared motor 17 (5V DC power supply, rated speed 150rpm, output torque 0.8kg·cm, insulation class E) is adopted. The motor comes with a metal gearbox (reduction ratio 1:100) to ensure stable output torque.

[0234] - Central motor installation: It is fixed to the center of the base 10 with plastic clips (the clips fit the motor housing ≥90%). The motor shaft has a diameter of 3mm and needs to pass through a 3.1mm diameter through hole opened at the top of the base 10 (the gap between the through hole and the shaft is ≤0.1mm to prevent the particles of snacks from seeping in). The end of the shaft is fixed to a rectangular rotating plate 18 (ABS material, 4cm long × 2cm wide × 0.5cm thick, with 0.5mm deep anti-slip texture on the surface to increase the friction with the snacks) through an ABS material coupling (3mm inner diameter, 10mm length).

[0235] - Front motor installation: Fixed to the front of the base 10 near the outlet position using plastic clips. The motor rotating shaft is fitted with a Z-shaped stainless steel connecting rod 16 (3mm diameter, 90° bending angle, galvanized surface for rust prevention, coating thickness ≥5μm). One end of the connecting rod is fixed to the rotating shaft with an M2 set screw (screw depth ≥1mm), and the other end is connected to an ABS valve 15 (4cm×2cm×0.3cm) with a 2mm diameter pin. The valve 15 is engaged in the rectangular groove inside the base 10 (groove width 4.1mm, depth 2cm), ensuring that the valve 15 can move up and down along the groove (stroke 1cm, error ≤0.1mm).

[0236] ②. Category B: Beverage type (Miniature water pump 30)

[0237] - Water pump 30 selection: Use DC50E model miniature water pump 30 (5V DC power supply, rated flow 1.5L / min, maximum head 1.5m, working current ≤800mA), the pump body material is food grade PP to ensure safety when in contact with beverages.

[0238] - Pipe connections:

[0239] - Water inlet pipe: Use food-grade silicone tubing (inner diameter 8mm, wall thickness 2mm, conforming to GB 4806.11-2021 standard). One end is sealed with an O-ring (10×1.5mm, single-person type) or 12×1.5mm (double-person type) and inserted into the bottom of the beverage container (1cm away from the bottom of the container to ensure thorough extraction). The other end is connected to the water pump inlet through a pagoda connector (the connector insertion depth is ≥5mm to prevent it from falling off).

[0240] - Outlet bend 23: Same specifications as the inlet pipe, one end connects to the water pump outlet, and the other end extends through the outer main unit 20 housing to the outside (extending length ≥ 5mm), with a silicone dispensing nozzle installed at the end (inner diameter 5mm, length 10mm, dispensing direction vertically downward to avoid beverage splashing); excessive bending should be avoided at pipe bends (bending radius ≥ 10mm) to prevent pipe blockage.

[0241] - Installation differences: The single-person model has one water pump fixed in the component box 24, and the water outlet bend 23 corresponds to the cup groove in front of the main unit 20; the double-person model has one water pump 30 fixed in each of the component boxes 24 on both sides, and the water outlet bend 23 corresponds to the cup groove on both sides respectively. The distance between the liquid outlets on both sides is 10cm, which is suitable for two people to drink at the same time.

[0242] 3. Specific implementation of unified circuit structure and signal link

[0243] The circuit signals of all three sub-devices follow a closed-loop process of "input → processing → counting → triggering → execution → reset". The specific implementation steps are as follows:

[0244] (1). Signal input and conversion: The audiobook 1 plays the knowledge point audio (60-80dB) → the rubber sleeve focuses the signal → the microphone converts the sound signal into a 0.1-0.5V analog electrical signal → the shielded electronic wire transmits the analog electrical signal to the signal input terminal 26 of the control circuit board 14; during actual testing, it is necessary to ensure that the analog electrical signal is free of noise (observed by an oscilloscope, waveform distortion ≤5%).

[0245] (2). Signal Processing and Counting: The analog electrical signal enters the sound sensor module → the module amplifies the signal by 100 times and converts it into a 3V low-level switching signal → the switching signal is transmitted to the CLK terminal of the CD4518 counting chip → the chip counts and accumulates (count +1 for each signal received) → the BCD code output by the CD4518 is transmitted to the CD4511 chip → the CD4511 converts the BCD code into a seven-segment display signal, driving the digital tube 3 to display the count in real time (range 00-99); during the counting process, it is necessary to ensure that the digital tube 3 display is flicker-free (brightness ≥300cd / m²). 2 (Viewing angle ≥ 120°).

[0246] (3). Threshold triggering and driving: When the count reaches the preset threshold (default 10 times, the threshold can be changed by adjusting the external resistor of the CD4518 chip) → the CD4518 chip CO terminal outputs a high-level trigger signal → the trigger signal is transmitted to the L293D motor drive module → the drive module synchronously outputs 5V drive current to the actuator and electric toy 11, and at the same time powers the NE555 delay circuit module → the delay module outputs a high level to maintain the working state of the drive module.

[0247] (4) Prize distribution and linkage:

[0248] - Solid Particle Type: The central motor rotates forward, driving the rotating plate 18 to push the snack to the bottom outlet of the container → the front motor rotates forward, driving the connecting rod 16 to pull the valve 15 downward by 1cm, opening the outlet → the snack naturally falls into the prize receiving container 4; at the same time, the electric toy 11 receives the driving current, the red / blue LED beads flash alternately (interval of 0.5 seconds), the speaker plays cartoon sound effects (decibel ≤65dB), and the eccentric wheel motor drives the spring to achieve a jump of ≤3cm.

[0249] - Beverage type: The water pump 30 starts and draws the beverage through the inlet pipe → After the beverage is pressurized by the pump body, it is delivered to the outlet nozzle through the outlet bend 23 and poured into the cup (single output volume 200ml, completed within 10 seconds); the electric toy 11 starts the sound and light and jumping action simultaneously.

[0250] (5). Reset standby: 10-second delay ends → NE555 delay module output level flips (high level → low level) → L298N drive module stops working, execution parts and electric toy stop (solid particle type front motor reverses, driving valve 15 to move upward to close the outlet) → high level output of delay module disappears, CD4518 counter chip is cleared → digital tube 3 displays "00" → device returns to standby state, waiting for the next signal trigger.

[0251] 4. Specific Implementation of General Design Standards

[0252] -Safety Design:

[0253] - Material Safety: Containers, receiving containers, and tubing that come into contact with prizes are all made of food-grade materials (PET, PP, silicone), and material testing reports (compliant with GB 4806 series standards) must be provided; non-food contact parts (such as bases and component boxes) are made of ABS material with formaldehyde emission ≤0.1mg / m³. 3 .

[0254] -Circuit safety: The lithium battery 13 comes with a built-in charge and discharge protection board to prevent overcharging, over-discharging, and short circuits; the motor drive module is connected in series with a 10A self-resetting fuse, which automatically disconnects the circuit in case of overload; all electronic wire connectors are coated with insulating varnish to prevent short circuits and leakage.

[0255] -Safety in use: The combination lock 8 uses a 3-digit design and the unlocking force is ≤5N to prevent children from accidentally opening it; the jumping range of the electric toy 11 is controlled by the weight of the eccentric wheel (≤3cm) to avoid jumping too high and causing it to tip over; the edges of the main body shell are all rounded (rounded radius ≥2mm) to prevent children from being scratched.

[0256] - Adaptive design:

[0257] - Power supply compatibility: All actuators are powered by 5V DC, and the battery life can be extended by replacing the lithium battery 13 with the same specification; the charging female connector 25 adopts the universal DC-005 specification and is compatible with mainstream 5V / 1A chargers on the market.

[0258] -Signal compatibility: The signal acquisition component is compatible with mainstream children's audiobooks (speaker diameter 20-30mm) on the market. By changing the rubber sleeve of different sizes, it can be compatible with audiobook speakers of different specifications.

[0259] -Structural compatibility: The control circuit boards 14, lithium batteries 13, and electric toys 11 of solid granule type and beverage type are completely compatible. Type conversion can be achieved simply by plugging and unplugging the connecting wires (replacement time ≤ 5 minutes).

[0260] -Operational Design:

[0261] - External operating components: The digital tube 3, power switch 5, charging socket 25, and terminal block all protrude externally (protrusion height 2-3mm) to facilitate independent operation by children; the cleaning button 19 is only provided on the beverage type and is located on the side of the component box 24 facing the container to avoid accidental external contact.

[0262] -Automated process: The entire prize output process requires no manual intervention, only two steps: "press the power switch 5" and "use the voice book 1", which is suitable for children's usage habits; the digital tube 3 displays clearly, making it easy for users to check the remaining count.

[0263] II. Detailed Implementation of the Three Parallel Sub-devices

[0264] 1. Sub-device 1: Solid Particle Snack Prize Machine Device (see...) Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 8 , Figure 9 )

[0265] This device is specifically designed for the quantitative output of solid granular snacks (such as popcorn, peanuts, and nuts with a particle diameter of 3-10mm). It adopts a split structure of "upper container + lower base 10". The specific implementation details are as follows:

[0266] (1). Overall structural assembly

[0267] ①. Assembly of the upper prize container 7: Assemble the gourd-shaped container (20cm high, 8cm maximum diameter) made of food-grade transparent PET material with the container lid 8 with a 3-digit combination lock. Insert the lock into the buckle groove on the edge of the container opening (insertion depth ≥ 5mm) to ensure that the lid is secure after closing. Fill the container with granular snacks (filling amount ≤ 80% of the container volume, such as popcorn filling amount ≤ 100g) to avoid excessive snacks causing jamming.

[0268] ②. Assembly of the lower base 10:

[0269] - Component fixing: The central micro geared motor 17-1 is fixed to the central mounting slot of the base 10 with a buckle, and the front micro geared motor 17-2 is fixed to the front mounting slot of the base; the control circuit board 14 is fixed to the boss on the inner front side of the base 10 with 4 M2 screws, and the lithium battery 13 is fixed to the circuit board 1cm above it with a plastic bracket (the spacing is ≥3cm to avoid heat dissipation).

[0270] - Wiring connection: Connect the lithium battery 13 to the power management module of the control circuit board 14, the motor to the motor drive module of the control circuit board 14, and the shielded electronic wire to the signal input terminal block 26 using terminal wires; all wires must be fixed by the wire clips inside the base 10 (wire clip spacing ≤ 5cm) to avoid messy wires causing short circuits.

[0271] - External component installation: Insert the digital tube 3, power switch 5, and charging socket 25 into the front through hole of the base 10 and fix them with screws; fix the prize receiving container 4 to the front of the base 10 with M2 screws (alignment accuracy with container output port 6 ≤ 2mm); fix the dust cover to the bottom of the base 10 with 4 M3 screws to ensure that the dust cover fits tightly with the base 10.

[0272] ③. Upper and lower connection: Align the buckle at the bottom of the upper snack prize container 7 with the slot at the top of the lower base 10, and press vertically downward (pressing force ≥10N) until the buckle is fully engaged (insertion depth ≥5mm) to ensure that the upper and lower connection is firm and without looseness (no abnormal noise when shaking).

[0273] (2). Power Link (Full Path Visualization)

[0274] ①. Main power supply link (from power source to load)

[0275] a. Charging stage: External 5V / 1A charger → Charging female connector 25 (Micro-USB interface) → Power management module TP4056 (input 5V, output 4.2V) → Lithium battery terminal block 29 → Lithium battery 13 (charging current ≤500mA, onboard LED indicator lights up red, turns green when fully charged);

[0276] b. Discharge stage: Lithium battery 13 (output 5V) → Lithium battery terminal block 29 (terminal 1 → red wire → power switch) → 5-way output:

[0277] -Channel 1: 5V → Sound sensor module (LM393 chip VCC pin) → Common ground GND;

[0278] -Channel 2: 5V → Counter module (CD4518 chip VDD pin, CD4511 chip VCC pin, NE555 multivibrator, including external resistors and capacitors) → Common ground GND;

[0279] -Channel 3: 5V → Motor drive module (L293D chip VCC pin) → Common ground GND;

[0280] -Channel 4: 5V → A delay circuit module (555 chip VCC pin) → GND;

[0281] -Channel 5: 5V → 1K resistor → B delay circuit module (555 chip VCC pin) → GND;

[0282] ②. Independent control link at the load end (main link branch, corresponding to the specific execution component)

[0283] Based on the discharge general path in ①, the independent power supply paths for each load are subdivided, and the precise connection between "drive module → execution unit" is clearly defined:

[0284] a. Power supply link for miniature geared motor:

[0285] Motor drive module L293D (OUT1 pin) → Terminal block → Micro geared motor 28-1 (central rotating plate 36 drive) pin 1 → Micro geared motor 28-1 pin 2 → Terminal block → Motor drive module L293D (OUT2 pin) → Common ground GND; Motor drive module L293D (OUT3 pin) → Terminal block → Micro geared motor terminal block 28-2 (front valve opening drive) pin 1 → Micro geared motor 28-2 pin 2 → Terminal block → Motor drive module L293D (OUT4 pin) → Common ground GND; Motor drive module L293D (OUT4 pin) → Terminal block → Micro geared motor terminal block 28-2 (front valve closing drive) pin 2 → Micro geared motor 28-2 pin 1 → Terminal block → Motor drive module L293D (OUT3 pin) → Common ground GND;

[0286] (Note: The two motors are powered independently and their on / off states are controlled by the IN1 / IN3 pins of the L293D chip, respectively, without interference between them.)

[0287] b. Power supply link for electric toys:

[0288] Motor drive module L293D (OUT1 pin) → Electric toy terminal block 27 (PH2.0-2P specification) → Electric toy 11 (internal sound and light components + jump motor) → Common ground GND;

[0289] (Linkage logic: Synchronous on / off with motor power supply, controlled by L293D chip to ensure coordinated "prize output - toy action").

[0290] c. Power supply links for display and operating elements:

[0291] Control circuit board 14 main power supply → digital tube 3 (common cathode, VCC pin) → common ground GND;

[0292] The power supply link described above can be visualized through a hierarchical logic of "power source → main path → branch → load → protection". Here, ① is the main path framework and ② is the load branch details. Together, they constitute a complete power supply path, ensuring that every step from external charging to power supply of internal execution components is clearly traceable and without any path breaks.

[0293] (3). Signal link (corresponding) Figure 8 (Process, step to pin)

[0294] ①. Signal acquisition and conversion ( Figure 8 ①-②)

[0295] a. Voicebook 1 plays voice (frequency 1kHz-3kHz, loudness ≥60dB) → Microphone 2-1 (picks up sound) → converts the sound signal into a 0.1V-0.5V analog electrical signal → through microphone line 12 → signal input terminal block 26 (terminal 1) → sound sensor module LM386 chip IN pin;

[0296] b. The sound sensor module sets the threshold (corresponding to an analog electrical signal of 0.3V) through a 10kΩ adjustable resistor: when the input signal is ≥0.3V, the OUT pin of the LM393 chip outputs a high level (5V) and then flips to a low level (0V) → output to the CLK pin of the CD4518 counting module chip (trigger counting).

[0297] ②. Counting and Judgment ( Figure 8 ③-④)

[0298] a. The CD4518 chip (counting mode) receives a high-level signal from the trigger signal input of the multivibrator of the NE555+ resistor and capacitor device into the CLK pin, and the internal counter increments by 1 → the count signal is output from the Q4 pin → the ABCD pin of the CD4511 chip (BCD code input).

[0299] b. The CD4511 chip converts the BCD code into a digital tube drive signal → Digital tube 3 (two common cathodes, pin ag) → Displays the count (e.g., the 5th trigger displays "05");

[0300] c. When the count reaches the preset value of 10 times, the Q5 pin (carry terminal) of the CD4518 chip (judgment mode, another counting unit) outputs a high level (5V) → +4148 switching diode → trigger signal is transmitted to the IN1 pin of the motor drive module.

[0301] ③. Delay and Driver Execution ( Figure 8 ⑤-⑥)

[0302] a. CD4518 counting module (pin 12 carry output, counts 10 times) → +4148 switching diode → Motor drive module IN1 pin → Motor drive module output OUT1 (divided into two paths) → Path 1: Electric toy terminal block → drives electric toy; → Path 2: A delay circuit module VCC terminal (has the characteristic of starting delay upon power-on) → A delay circuit output → divided into four paths:

[0303] - First path: A delay output → +4148 switching diode → motor drive module (IN1, A motor positive input terminal) → A motor (forward operation, driving the rotating plate to transport snacks);

[0304] - Second path: A delayed output → motor drive module (IN3, B motor positive input terminal) → B motor (forward operation, valve open);

[0305] -Third path: A delay output → NPN transistor (base turned on) → B delay circuit module (power supply cut off, power supply stopped).

[0306] - Fourth channel: A delay output → 4518 counting module chip clear terminal → realize count clearing (when the delay ends, the output terminal flips from high level to low level, and the counting module is in the counting enabled state).

[0307] bA: Power supply link: positive power supply → 1K current limiting resistor → B delay circuit module VCC terminal

[0308] B: Transistor connection link:

[0309] -B Delay Circuit Module VCC Terminal → NPN8050 Transistor Collector (C Terminal)

[0310] - NPN8050 transistor emitter (E) → GND (to ground)

[0311] -A Delayed Output Signal → NPN8050 Transistor Base (B)

[0312] cA Delay Circuit Module (Delay ends, output reset) → Transistor (cut off) → B Delay Circuit Module (Power supply restored) → B Delay Circuit RC Regulation Network (Sets valve closing delay) → B Delay Circuit Output → Motor Drive Module (IN4, B Motor Reverse Input) → B Motor (Reverse rotation, valve closed)

[0313] This circuit includes an AB dual-delay circuit module. The motor drive module (L293D chip) has four independent signal input terminals, corresponding to the forward and reverse rotation control of two micro geared motors: the positive input terminal (IN1) and the reverse input terminal (IN2) of motor A (driving the rotating plate, responsible for snack delivery), and the positive input terminal (IN3) and the reverse input terminal (IN4) of motor B (driving the valve, responsible for opening and closing the snack outlet). The forward and reverse rotation of motor A does not affect the snack output effect; it only needs to achieve the action of "delivering snacks to the outlet." The forward and reverse rotation of motor B directly corresponds to the "opening" and "closing" of the valve, with a clear logical connection. The carry terminal of the counting module is connected to the IN1 pin of the motor drive module via a diode, enabling the motor to output a snack prize when a preset threshold of 10 counts is reached.

[0314] (4) Coordination of key actions (mechanical + electrical linkage)

[0315] -Valve and rotating plate synchronization: Motor 17-1 (rotating plate) starts only after motor 17-2 (valve) starts - achieved through the A delay circuit module of motor drive module L293D;

[0316] -Electric toy start-up: Motor drive module OUT1-OUT2 → Electric toy terminal block;

[0317] -Electric toy linkage timing: Electric toy 11 and motor 17-1 are powered on and off synchronously - controlled by the same power supply of the motor drive module to ensure that "the toy starts when the snack is released and stops when the snack stops", enhancing the user interaction.

[0318] 2. Sub-device two: Single-person beverage prize machine device (see...) Figure 5 , Figure 7 , Figure 8 , Figure 10 )

[0319] This device is specifically designed for the quantitative output of liquid beverages (such as juice and milk with a viscosity ≤100mPa·s) in a single-person setting. It adopts an inner and outer nested structure of "transparent hollow cylindrical main unit 20 + built-in single-sided component box 24". The specific implementation details are as follows:

[0320] (1). Overall structural assembly

[0321] ①. Outer Main Unit 20 Housing Assembly: Assemble the hollow cylindrical housing (22cm high, 10cm in diameter) made of transparent ABS material with the top circular cover 22. The cover 22 is fixed by plastic buckles (buckle insertion depth ≥3mm). The silicone sealing ring inside the cover ensures a seal (no liquid leakage). A silicone anti-slip pad is pasted in the circular groove at the front of the housing. The mounting position of the component box 24 reserved on the side of the housing is cleaned (no burrs).

[0322] ②. Assembly of the inner beverage container 21 and component box 24:

[0323] - Beverage container 21: Fill a food-grade PET bottle-shaped container (capacity 500ml) with an appropriate amount of beverage (e.g., 300ml of juice), tighten the threaded sealing cap with an O-ring (tightening torque ≥2N·m) to ensure no leakage; place the container into the reserved space in the middle of the main unit 20 housing, with the bottom of the container fitting snugly against the bottom of the housing.

[0324] - Component box 24: The DC50E water pump is fixed to the bottom of the component box 24 by a buckle, the control circuit board 14 is fixed to the middle of the component box 24 by screws, and the lithium battery 13 is fixed to the top of the component box 24 by a bracket; the wiring connecting the water pump 30 and the motor drive module of the control circuit board 14, and the lithium battery 13 and the power management module are fixed with wire clips (spacing ≤ 3cm); the cleaning button 19 is embedded in the button hole on the side of the component box 24 facing the container, with a protrusion height ≤ 2mm.

[0325] ③. Assembly of component box 24 and main unit 20: Fix the assembled component box 24 to the mounting position on the side of the main unit 20 housing using buckles (buckle insertion depth ≥ 3mm), ensuring that the component box 24 fits tightly with the housing; pass the water inlet pipe of the water pump 30 through the side wall of the component box 24 and insert it into the bottom of the beverage container 21 (1cm from the bottom of the container), fit an O-ring (specification 10×1.5mm) at the connection, and seal it with sealant (sealant thickness ≥ 1mm); pass the water outlet bend 23 through the through hole of the main unit 20 housing, and install a silicone dispensing nozzle at the end, with the dispensing nozzle facing the cup groove in front.

[0326] (2) Differences in power supply links (adjustment only at the load end)

[0327] The power supply and signal transmission of the single-user beverage prize machine (including the linkage device) and the solid granule snack prize machine are basically the same. The only differences are the addition of the cleaning button 19 and the adaptation of the actuator (water pump / motor). The core logic is completely the same.

[0328] - Motor drive module OUT1-OUT2 → Dual micro geared motor terminal block 28 (A3-A4) → Water pump (replacing rotating plate motor 17-1), the rest of the power supply links are completely the same as in Example 1; the terminal block of motor 17-2 is suspended;

[0329] The terminal block power supply for cleaning button 19 comes from the 5V power supply of control circuit board 14 (terminal 1 is connected to 5V, terminal 2 is connected to GND).

[0330] (3) Differences in signal links (new cleaning function logic added)

[0331] - Normal beverage output: The logic is consistent with "count → delay → drive" in Example 1. The water pump and motor 17-1 (rotating electric motor) terminal block are interchangeable. The motor 17-2 (rotating valve 15 motor) terminal block is suspended. The water pump 30 starts pumping water synchronously (pumping about 50mL of water within 10 seconds).

[0332] -Electric toy 11 Start-up: Motor drive module OUT1-OUT2 → Electric toy terminal block 27;

[0333] - Cleaning function triggered: Power supply VCC, GND → Cleaning button 19 → Water pump 30 starts to achieve cleaning.

[0334] (4). Selection of cleaning button 19, connection method and welding process of component box through-type (drinking container side).

[0335] ①. Selection: Self-resetting mechanical button (model TS-A001, diameter 12mm);

[0336] ②. Soldered to the side of the control circuit board 14 facing the beverage container 21, the button head passes through the opening in the side wall of the component box 24 (with silicone dust cover) and protrudes 3mm from the outside of the component box 24; the micro water pump 30 can be triggered to run by simply pressing it manually, and the water inlet pipe, the inside of the water pump and the water outlet pipe 23 are cleaned to prevent the beverage residue from breeding bacteria.

[0337] ③. One end of the cleaning button 19 is connected to the 5V power supply of the control circuit board 14, and the other end is connected to the IN1 pin of the motor drive module. When the button is pressed, the water pump 30 is directly triggered to run. When the button is released, it stops, realizing the manual cleaning function.

[0338] 3. Sub-device three: Two-person beverage prize machine device (see...) Figure 6 , Figure 7 , Figure 8 , Figure 10 )

[0339] This device is specifically designed for two-person competitive learning scenarios. It adopts a nested structure of "transparent cylindrical main unit 20 + double-sided symmetrical component box 24" to enable independent operation and synchronous use by two people. The specific implementation details are as follows:

[0340] (1). Overall structural assembly

[0341] ①. Outer Main Unit 20 Housing Assembly: The hollow cylindrical housing (height 22cm, diameter 15cm) is made of transparent food-grade PET material. The top circular sealing cover integrates a 3-digit digital combination lock 8, and a silicone sealing ring is nested inside the cover (sealing pressure ≥0.2MPa). There are 2 component box 24 mounting positions symmetrically opened on both sides of the housing, and 2 cup grooves (10cm apart) are symmetrically opened on the front. Silicone anti-slip pads are pasted in the grooves.

[0342] ②. Assembly of the central shared beverage container 21: Fill the shared bottle-shaped container (capacity 1000ml) made of food-grade PET material with beverage (e.g., 800ml of milk), and tighten the threaded sealing cap (thread specification M30×1.5); install O-rings (specification 12×1.5mm) on the two water outlets at the bottom of the container to ensure a seal.

[0343] ③. Assembly of double-sided component boxes 24:

[0344] - Assembly of single-sided component box 24: The assembly process is the same as that of the single-person beverage prize machine component box 24, including fixing and wiring the water pump, control circuit board 14, lithium battery 13, and soldering the cleaning button 19 to ensure the complete functionality of the single-sided component.

[0345] - Symmetrical installation on both sides: Fix the two component boxes 24 to the mounting positions on both sides of the main unit 20 housing with buckles (bucket insertion depth ≥ 3mm, symmetry deviation of the two component boxes 24 ≤ 1mm); the water inlet pipes of the two water pumps 30 pass through the side walls of the component boxes 24 and are inserted into the bottom of the central container on both sides (1cm away from the bottom of the container), and the connection is double-sealed with sealing ring + sealant; the two water outlet bends 23 pass through the corresponding side through holes of the main unit 20 housing, and the liquid outlets are aligned with the respective cup grooves (10cm apart).

[0346] ④. External component installation: The dual-sided digital tube 3, power switch 5, charging female socket 25, and electric toy terminal block 27 are respectively embedded in the through holes on both sides of the main unit 20 to ensure that the layout of the components on both sides is symmetrical (deviation ≤0.5mm) and facilitates simultaneous operation by two people.

[0347] (2). Power and signal link description for a two-person beverage prize machine

[0348] The core of the two-person beverage prize machine is "two sets of single-person systems symmetrically mirrored," sharing only one beverage container 21. The power supply and signal link logic are completely reused from the single-person system, as detailed below:

[0349] ①. Power supply link

[0350] Each side is equipped with an independent power supply system (18650 lithium battery + TP4056 power management module), consistent with the single-person model.

[0351] -Single side: Lithium battery 13 → Power management module → Control circuit board on the same side (various functional modules) → Water pump / electric toy, stable 5V power supply;

[0352] -Dual-sided: The layout is symmetrical with the shared container as the center. Turning on or off and charging on one side will not affect the other side, making it completely independent.

[0353] ②. Signal Link

[0354] Each side has an independent signal closed loop, and the process is the same as the single-person type:

[0355] -Single side: Voice book → rubber cover → microphone → shielded electronic wire → same side control circuit board (amplification → counting → triggering) → water pump / toy linkage → reset;

[0356] - Bilateral: Signal acquisition and processing do not interfere with each other. When the left side is triggered, only the left side moves. The same applies to the right side, which is equivalent to two independent single-person models.

[0357] ③. The only difference

[0358] Replace the individual container of the single-person model with a shared food-grade container, with two water outlets at the bottom. The water inlet pipes (food-grade silicone tubes) of the water pumps on both sides are inserted into the outlets (with sealing rings for sealing). All other parts and connection methods are the same as the single-person model.

[0359] (4). Rules for the Competition of the Two-Player Beverage Prize Machine

[0360] The competition logic of the two-person beverage prize machine is based on the design of "independent operation, shared resources, and more work, more pay". There is no collaborative connection or mutual interference between the two sides. The core rule is not "exclusive competition of either / or", but "competition based on profit difference based on public beverage resources", which is explained in detail below:

[0361] ①. Both sides operate completely independently, without any cooperative interference.

[0362] The two devices are two independent "voice trigger-counting-prize output" systems with no circuit connections or signal interaction: the left and right voicebook triggers counting independently. When the left reaches the threshold and outputs a beverage, it will not trigger the right to reset the count or stop running. Similarly, when the right outputs, the left can still accumulate count normally. There is no limitation that "one side's profit will prevent the other side from profiting". The prize-winning opportunity is determined entirely by the operation frequency of the users on both sides (such as the number of times the voicebook is used).

[0363] ②. Public beverage containers are a shared resource; profits are based on differences in output volume.

[0364] The centrally shared beverage container (1000ml) is the only shared component on both sides. Although the water inlet pipes of the water pumps on both sides are connected to the container simultaneously, there is no "quota restriction" or "output interlock".

[0365] - If the user on the left performs more frequent actions (e.g., triggers 20 times and outputs 400ml of beverage), while the user on the right performs fewer actions (e.g., triggers 10 times and outputs 200ml of beverage), then the user on the left will obtain more beverages and will profit more significantly.

[0366] Even if one side continues to output, as long as there is still beverage in the container, the other side can still trigger output normally until the beverage in the container is exhausted (which requires an adult to replenish). In essence, it is a competition logic of "whoever triggers more times gets more beverage resources", rather than a zero-sum competition of "you gain and I lose".

[0367] ③. The core of the competition is the "difference in operational efficiency," not the "exclusive victory or defeat."

[0368] The competition rules emphasize "incentivizing proactive action": users on both sides accumulate counts by using audiobooks (such as answering questions and learning knowledge points). Reaching a certain count threshold allows users to independently obtain drinks, with the final reward based on the "total number of drinks obtained." For example, in a children's learning scenario, "whoever masters more knowledge points (more triggers) receives more drink rewards," encouraging both parties to actively participate in learning. This eliminates the need to "restrict the other party's gains" to achieve the competition objective, better meeting children's interactive needs. III. Explanation of the Link Consistency and Terminal Block Universality between Sub-devices Two and Three and Sub-device One

[0369] Sub-devices 2 (single-person beverage prize machine) and 3 (double-person beverage prize machine) share the same core power and signal links as sub-device 1 (solid granule snack prize machine), and their critical "actuator terminal blocks" (motor / water pump terminal blocks) are interchangeable. Essentially, it's a design where "one control circuit board 14 adapts to multiple types of devices," as detailed below:

[0370] 1. Power supply and signal links: The entire process is consistent, with differences only in the compatibility of the components used.

[0371] The core architecture, chip interaction, and program logic of both types of links are completely identical to those of Sub-device 1. Refer directly to the corresponding section in "Detailed Implementation - Sub-device 1". The only difference lies in the adaptability of the triggering object of the execution component; there are no changes to the link itself.

[0372] (1) Power supply link: The power supply architecture is unified, and the terminal blocks are reused as needed.

[0373] ①. Core consistency: Both follow the architecture of "lithium battery 13 → TP4056 power management module → branch power supply to functional modules (sound sensor / counter / delay) → execution unit", with a power supply voltage of 5V and identical charging and discharging protection logic;

[0374] ②. Adaptation differences: Sub-device 1 supplies power to the micro geared motors 17-1 / 17-2 through dual motor terminal blocks, while sub-devices 2 and 3 supply power to the water pump through the same terminal block (only one set of terminal blocks is connected, and the other set is left unconnected); the newly added cleaning button 19 in sub-devices 2 and 3 is directly connected to the cleaning button terminal block 30 reserved on the circuit board, without the need to add an additional power supply circuit, and the power supply branching logic of sub-device 1 is not changed;

[0375] ③. Dual-person adaptation: Sub-device three is equipped with a power link on each side that is consistent with sub-device one. The two sides are powered independently and do not interfere with each other. They only share the central beverage container and there is no additional power supply design.

[0376] (2). Signal Link: Unified closed-loop process, adapted trigger objects

[0377] ①. Core consistency: Both follow the closed loop of "voice book 1 signal → microphone → shielded wire → sound sensor → CD4518 counting → L293D driver → execution unit + electric toy 11 linkage → reset". The counting threshold, delay logic (default 10 seconds) and electric toy linkage (sound and light + jump) are exactly the same.

[0378] ②..Adaptation differences: Sub-device one triggers the dual motor action (pushing snacks + opening and closing valves), while sub-devices two and three trigger the water pump to run (outputting beverages). The signal triggering logic is the same. The cleaning function only requires pressing the cleaning button to directly turn on the water pump power. It does not need to go through the "counting-triggering" link of sub-device one. It belongs to the independent function multiplexing of the terminal block and does not change the core signal transmission.

[0379] ③..Dual-person adaptation: The signal links on both sides of sub-device three are consistent with those of sub-device one. The signal on the left side only triggers the left counter and the water pump, and the same applies to the right side. There is no signal interaction between the two sides, which is equivalent to the symmetrical distribution of the signal links of two sets of sub-device one.

[0380] 2. Terminal block for actuator: The terminal blocks for motors and water pumps are completely interchangeable.

[0381] Sub-device one connects to the terminal block of the micro geared motor 17-1 / 17-2, and sub-devices two and three connect to the terminal block of the water pump. They are of the same specification and are universally compatible, requiring no modification to the interface or wiring.

[0382] (1). Universal specifications: all are PH2.0-2P specifications, terminal spacing 2.0m, insertion and extraction force ≥3N, pin definitions (positive and negative) are fully matched, and the water pump terminal wires can be directly inserted into the motor terminal block without replacing the terminal head;

[0383] (2). Logic is universal: Both types of terminal blocks are connected to the output of the L293D motor drive module. The received drive signal (5V current) and signal triggering logic are the same. Only the action mode of the executing component (motor / water pump) is different. The signal transmission function of the terminal block is the same.

[0384] (3) Flexible use: The dual motor terminal block of sub-device one can be flexibly switched and adapted - connecting the motor can realize the output of solid granular snacks, connecting the water pump can realize the output of beverages, and the unused terminal block only needs to be suspended (for example, when used in a solid snack prize machine, the terminal block of the cleaning button is suspended and not connected to the load; when used in a beverage machine, the valve motor terminal block 28-2 should be suspended) without affecting the overall link stability, truly realizing "one set of terminal blocks adapts to multiple types of actuators".

[0385] 3. Core Conclusions

[0386] The consistency of the link and the universality of the terminal blocks between sub-devices two and three and sub-device one are essentially due to the "universal design" of the control circuit board. The circuit board of sub-device one has reserved the terminal blocks required for the beverage type (universal terminal blocks for motors / water pumps and cleaning button terminal blocks). Subsequent sub-devices only need to connect to the corresponding execution components as needed, without modifying the circuit structure, link logic or program. This simplifies the design and ensures that the core technical solutions of each sub-device are consistent, which is in line with the innovative logic of "structural reuse and functional expansion" of the patent.

[0387] IV. Supplementary Explanation of the Implementation Examples

[0388] 1. Description of Device Parameters: In this embodiment, the specific dimensions (such as height and diameter), component box size, water pipe length, etc., of the main unit are not limited. This is because the specific size, length, material, and other parameters can be flexibly selected based on the actual application scenario, user needs and preferences, and the availability of common components in the market. Changes in the above parameters will not affect the implementation and realization of the core technical solution of this invention. These parameters may only affect the appearance and installation space of the device, without changing the core logic of "storage-transmission-output". Those skilled in the art can flexibly adjust them according to the actual scenario, such as ensuring that the liquid container 20 is compatible with the water pump installation and that the water pipe meets the transmission requirements.

[0389] 2. Explanation of the universality of electronic modules: The sound sensor module and delay circuit module mentioned in this embodiment are all universal standardized modules (such as KY-037 and NE555 delay modules). Modules with the same function produced by different manufacturers (such as the sound sensor with model LM393 and the delay module with model CD4060) can be directly replaced because the power supply interface (5V) and signal interface (IN / OUT) of these modules conform to industry standards and the same function can be achieved without modifying the circuit structure.

[0390] 3. Description of Electric Toy 11: In this embodiment, the electric toy 11 adopts a cartoon dog shape, but the present invention does not limit the specific shape of the toy (such as cartoon cat, cartoon car, etc.). As long as the toy meets the conditions of "5V power supply, can be fixed by spring, and can realize sound and light action", it can be connected to the electric toy terminal block 27 through the connecting wire to realize the linkage function. The cartoon dog shape is only a preferred example for child-friendliness. 4. Appendix Figure 7 illustrate:

[0392] ①. Solid granule type snack prize machine: The cleaning button terminal block 30 can be omitted in terms of terminal block; the motor wiring method is to connect two micro geared motors to two corresponding terminal blocks 28.

[0393] ②. Single-person beverage prize machine: The cleaning button terminal block 30 must be retained in the terminal block; the motor wiring method is to connect the micro geared motor / water pump terminal block 28 to the water pump drive.

[0394] ③. Double-person beverage prize machine: The terminal block for the cleaning button 30 should be retained. The motor wiring method is to connect the micro geared motor terminal block 28 to the water pump drive (this double-person device has two circuit boards).

[0395] ④. The specific circuit structure, connection relationships and parameters shall be based on the text description in the "Specific Implementation Method" section of the instruction manual.

[0396] ⑤. Related attached diagrams: Figure 2 (Actual control circuit board) Figure 5 (Single-person beverage machine) Figure 6 (Double-person beverage machine)

[0397] If the aforementioned terminal blocks are inserted incorrectly, they can be readjusted without affecting the motor. Furthermore, the terminal blocks can be left unconnected when there is no matching load. For example, when the circuit board is used in a beverage machine, the terminal block for motor 17-2 is left unconnected (without a load). When used in a solid granule snack prize machine, the terminal block for the cleaning button is left unconnected.

[0398] 5. Appendix Figure 8This is a general workflow diagram for the three sub-devices, which visually presents the entire chain of "voice signal input → processing → counting → trigger execution → linkage to toy → reset standby" using "flow boxes + arrows". The text in the boxes corresponds one-to-one with the circuit links and functional modules in the specific implementation, and there is no new technical content (due to space limitations, the drive circuit flow of motor 17-2 is not shown).

[0399] The core of this diagram is to visualize the abstract core logic. It serves as a summary of the overall technical solution of this invention and helps to quickly understand the unified design concept of "voice-driven + toy linkage." It also helps to clarify the common logic and differentiated implementation of the three sub-devices (only the execution components are adapted to different prizes), allowing users to grasp the entire process without referring to the text. (Attached) Figure 8 In the text, the module identifier and serial number are explained.

[0400] To avoid excessive text, each functional module / unit box only displays the core name, and is uniquely identified by a circled Arabic numeral (①, ②...) next to it. The module details corresponding to each number are as follows:

[0401] a.①: The input is voice from the audiobook 1; the acquisition method is microphone cable 12 with terminal block, or microphone 2-1 / 2-2 (microphone) for pickup;

[0402] b.②: The component is a sound sensor module; its functions include three aspects: converting sound into electrical signals, setting a threshold through an adjustable resistor, and switching a high-level signal to a low-level signal when the signal is greater than or equal to the threshold.

[0403] c.③: The component includes a CD4518 chip, a CD4511 chip, and a digital tube 3; its function is to receive the switch signal from ② and count, while the digital tube 3 synchronously displays the count value (range 00-99);

[0404] d.④: The judgment rule is to compare the counting result of ③ with the preset value (e.g., 10 times); the component is a CD4518 chip (only calls the counting judgment function, does not count repeatedly); the function is to immediately output a high-level trigger signal to ⑤ (delay module) when the count reaches the preset value;

[0405] e.⑤: The component includes a 555 timer chip and resistors and capacitors (the delay time can be set, for example, 10 seconds); its function is to maintain the trigger signal output by ④ until the delay time ends.

[0406] f.⑥: The component is a motor drive module (integrated into the control circuit board 14); its core function is to support "one-to-three" load output, converting the trigger signals of the counting module ③ and the delay circuit module ⑤ into a single-channel drive current, while simultaneously powering three low-voltage actuators / modules; the output channels and compatible devices are specifically divided into three high-level output terminals, all compatible with 5V lithium battery 13 power supply:

[0407] - The first path is the drive end: providing drive current for the miniature geared motor 17-1 / 17-2 or the water pump;

[0408] - The second circuit is the power supply terminal one: providing working power for electric toys 11 / 11-1 / 11-2;

[0409] - The third path is power supply terminal two: providing operating power to delay circuit module ⑤;

[0410] At the same time, the delay circuit module ⑤ will output two currents. One current flows to the reset terminal of the counter ③ to achieve count reset, and the other current provides trigger current to the input terminal of the motor drive module ⑥. This current continues until the delay circuit module ⑤ disconnects after the timing ends. The motor drive module ⑥ then stops supplying power to the three loads, and finally achieves the synchronous stopping of the micro geared motor 17-1 / 17-2 (or water pump) and electric toy 11.

[0411] The direction of signal flow is indicated by the arrows in the attached diagram.

[0412] 6. The control circuit board is the core carrier for the integrated functionality, connecting various functional module components, chips, and terminal blocks via copper foil traces. The electronic components of each module (such as chip pins, resistor and capacitor leads, and terminal block leads) are directly soldered to their corresponding pads on the control circuit board. Electrical conduction is achieved through the copper foil traces on the board surface—no additional external wires are required. Signal transmission between CD4518 and CD4511, drive connections between delay circuits and motor interfaces, and signal / power transmission between terminal blocks and the core circuitry can all be achieved solely through the internal circuit wiring of the circuit board.

[0413] This design physically integrates all modules onto the same circuit board, namely the control circuit board, forming a complete signal link through internal circuitry. This simplifies the overall structure and ensures connection stability through fixed circuit wiring, facilitating fabrication according to drawings and mass production.

[0414] The connection between external components and the control circuit board is achieved through a dedicated terminal block.

[0415] The CD4518, CD4511, NE555, and other chips and functional modules (such as delay circuits) involved in this invention are all general-purpose standardized components or conventional circuit structures in the electronics field. Their pin definitions, electrical parameters, and typical application circuits are clearly described in publicly available chip datasheets, industry standard manuals, and textbooks, and are common knowledge to those skilled in the art. Technicians can implement connections by referring to the known chip datasheets, without needing to exhaustively examine every pin detail.

[0416] Therefore, the pin connections between chips (such as signal transmission between CD4518 and CD4511, and the cooperation between NE555 chip and peripheral components) and the circuit connections within the module (such as the parameter selection of resistors and capacitors, and the pin correspondence of terminal blocks) all follow general circuit design specifications and chip standard application schemes. Relevant technical personnel can obtain specific details by consulting the above-mentioned public information. There is no need to list the pin numbers or connection relationships one by one in the specification. They can still clearly understand and implement the circuit structure and function of this invention.

[0417] 7. Connection method between the soft rubber sleeve (with built-in microphone) and the voicebook speaker: It can be fixed with adhesive or by clamping the rubber sleeve to the edge of the voicebook at the speaker opening. Both methods ensure precise alignment of the microphone and speaker outlet, guaranteeing stable voice signal acquisition. Furthermore, continuous voice playback (without interruption) only triggers one count. A second count is triggered only after a certain interval (e.g., 3 seconds, the interval length depending on the parameters of the resistor-capacitor components in the delay circuit module) following a voice interruption.

[0418] The above three embodiments fully present the mechanical assembly, circuit connection, power and signal link, workflow and scene adaptation details of the present invention, ensuring that those skilled in the art can accurately reproduce the technical solution of the present invention based on this embodiment, combined with the publicly available chip datasheets (such as CD4518, M1555 datasheet) and component specifications, to realize the core function of "snack / liquid output and electric toy linkage", effectively stimulating children's learning and exercise.
