Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. However, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. It is worth noting that the communication connections, signal connections, and other methods involved are all known technologies, and the embodiments adopt existing connection methods.

[0025] Please see Figures 1 to 2 This embodiment provides an automatic wine vending machine with a wine mixing device. The wine vending machine is mainly composed of core components such as cabinet 1, wine storage tank 2, metering pump 3, control host 4, refrigeration unit 5, inert gas tank 6, normally closed solenoid valve, and wine mixing container 7. Through the coordinated operation of the core components, the automatic vending, mixing and blending of various types of bulk liquor and intelligent management can be realized.

[0026] The cabinet 1 is manufactured using sheet metal spraying technology, and has a hollow rectangular structure with dimensions of 120cm in length, 60cm in width, and 180cm in height. An internal transverse partition divides the cabinet 1 into two independent storage chambers. The upper chamber, measuring 120cm in length, 60cm in width, and 80cm in height, is used to neatly arrange twenty-four storage tanks, capable of holding 12 different types of baijiu (Chinese white liquor). Each type of baijiu has a new storage tank 21 and an aged storage tank 22. Each storage tank is 20cm in diameter and 50cm in height, arranged in a matrix of three rows and eight columns to maximize space utilization and facilitate maintenance. The lower chamber, measuring 120cm in length, 60cm in width, and 100cm in height, is used to install the metering pump 3, the control host 4, the refrigeration unit 5, the inert gas tank 6, and other mechanical components. A power module for external power supply is also located in the lower chamber.

[0027] The side panels, top panel, and bottom panel of cabinet 1 are all made of high-quality sheet metal with a thickness of 2mm. The surface is coated with a double-layer anti-rust and wear-resistant coating with a thickness of 0.1mm, effectively enhancing the service life of cabinet 1. Rubber strips with a cross-sectional dimension of 5mm×5mm are installed at the joints of cabinet 1 for sealing, forming a tight sealing structure. Tests show that under a pressure difference of 1000Pa, the gas leakage between the inside of cabinet 1 and the outside is less than 0.01m³ / h, ensuring that external dust and moisture cannot enter the interior of cabinet 1 and interfere with the liquor storage environment, while also preventing liquor leakage.

[0028] The front of the cabinet 1 features a 30cm x 20cm high-definition touchscreen as an information interaction interface 11. This interface 11 is connected to the control host 4 via a USB data cable for data transmission and command interaction. Below the interface 11 is a circular wine outlet 12 with a diameter of 3cm. This outlet 12 is connected to the mixing container 7 via a food-grade silicone hose with an inner diameter of 1cm. The hose's length is rationally arranged according to the internal structure of the cabinet 1 to ensure smooth delivery of the wine.

[0029] The back cover door of cabinet 1 is installed with detachable hinges. The door measures 80cm in length and 60cm in width, facilitating maintenance and repair of the internal equipment. An MC-38 magnetic door switch is installed on the back cover door. This magnetic door switch is wirelessly connected to the control host 4. When the back cover door is opened, the magnetic door switch transmits a signal to the control host 4 within 0.5 seconds. The control host 4 immediately triggers a built-in buzzer alarm, simultaneously recording the opening time and uploading it to the cloud management system.

[0030] There are twenty-four wine storage tanks 2 in total, all made of food-grade 304 stainless steel with a wall thickness of 1.5mm to ensure safe storage of the wine. Each wine storage tank has a designed capacity of 5L, which can meet daily sales needs. The wine storage tanks 2 are cylindrical, with polished interiors and a surface roughness Ra≤0.8μm for easy cleaning and maintenance.

[0031] The top of the wine storage tank 2 is equipped with a normally closed solenoid valve (model DF20-24V). This normally closed solenoid valve is connected to the control host 4 via a wire. Under normal conditions, the solenoid valve is closed, with a sealing pressure of up to 0.5 MPa, effectively preventing wine leakage and the entry of outside air into the tank. When the control host 4 receives a wine dispensing command, it sends a 24V DC voltage signal to the solenoid valve, which opens rapidly within 0.3 seconds, allowing the wine to flow out smoothly.

[0032] A YW-100 level sensor is installed near the top inside the storage tank 2. This sensor uses ultrasonic measurement and has an accuracy of ±1mm. The level sensor is connected to the control host 4 via a shielded signal cable, transmitting the level data to the host in real time. When the liquor level falls below the preset 1L level, the sensor sends a low-level signal to the control host 4. The control host 4 then uses the information interaction interface 11 to display a red warning icon and text indicating insufficient stock of the liquor, and simultaneously sends a replenishment notification to the staff's mobile app.

[0033] Each of the wine storage tanks 2 is equipped with an independent leak-proof device, which consists of a 3mm×3mm high-temperature resistant and alcohol-corrosion-resistant fluororubber sealing ring and a 2mm thick polytetrafluoroethylene sealing gasket. The sealing ring is installed at the interface between the wine storage tank 2 and the normally closed solenoid valve, and the sealing gasket is installed at the top sealing part of the tank. Testing has shown that the leak-proof device can effectively prevent wine leakage under a pressure of 0.3MPa.

[0034] The metering pump 3 is a high-precision plunger-type pump, model MP-50, with a maximum flow rate of 50 L / h and a metering accuracy of ±0.5%. The metering pump 3 mainly consists of a pump body, motor, transmission mechanism, and metering chamber. The pump body is made of polyvinylidene fluoride (PVDF), which has excellent corrosion resistance and can adapt to the chemical properties of baijiu (Chinese liquor). The metering motor is a 200W DC brushless motor, characterized by high efficiency and stability, with a speed control accuracy of ±1 rpm. The transmission mechanism adopts a crank-connecting rod structure, converting the rotational motion of the motor into linear motion, driving the plunger to reciprocate within the metering chamber, thus realizing the extraction and delivery of the liquor. All components of the transmission mechanism are made of high-precision, wear-resistant alloy steel, and undergo precision machining and assembly to ensure transmission accuracy and stability.

[0035] The metering chamber is precisely calibrated, with an internal diameter of 20mm, a stroke of 50mm, and a corresponding volume of 15.7mL. The metering pump 3 is connected to the control host 4 via an RS485 communication interface, receiving dispensing program instructions from the control host 4. For example, when a customer selects to purchase 500mL of a certain mixed wine on the information interaction interface 11, the control host 4 calculates the amount of wine to be drawn from each storage tank according to a preset mixing ratio and sends an instruction to the metering pump 3 of the corresponding storage tank. The metering pump 3 precisely controls the stroke and speed of the plunger according to the instruction, transporting the wine from the storage tank to the mixing container 7 through the dispensing pipe. During the delivery process, the flow sensor built into the metering pump 3 monitors the dispensing flow rate in real time and feeds the data back to the control host 4. The control host 4 adjusts the operating status of the metering pump 3 based on the feedback data to ensure the accuracy of the dispensing alcohol content.

[0036] The control host 4 employs a high-performance STM32H750 microcontroller system and utilizes AI control algorithms. The control host 4 mainly consists of a central processing unit (CPU), memory, storage module, communication module, and input / output interfaces. The CPU has a clock speed of 480MHz, possessing powerful computing capabilities, enabling it to quickly process various instructions and data, and run the AI ​​control algorithm to intelligently control the entire wine vending machine. The memory uses 256MB of DDR4-3200 memory to store temporary data generated during program execution, ensuring smooth program operation. The storage module uses a 16GB eMMC storage chip to store important data such as the vending machine's system program, wine information, and user data, ensuring data security and reliability.

[0037] The communication module includes a wireless communication module (model ESP32-S3) and a wired communication module (model MAX3232). The wireless communication module supports Wi-Fi and Bluetooth communication protocols, enabling wireless communication between the control host 4 and the information interaction interface 11 and the mobile APP. The wired communication module uses an RS485 communication interface to enable communication between the control host 4 and devices such as the metering pump 3, level sensor, and door magnetic switch, ensuring real-time data transmission and accurate command execution.

[0038] The input / output interface adopts a standard GPIO interface for connecting the control host 4 to external devices. The control host 4 receives user operation commands from the information interaction interface 11 through the input / output interface, processes them, and sends control signals to devices such as the metering pump 3 and the normally closed solenoid valve to achieve automated control of the wine dispensing process. Simultaneously, the control host 4 can also transmit data such as the operating status and fault information of the wine dispensing machine to external devices through the input / output interface, facilitating remote monitoring and management by staff. For example, when the control host 4 detects a fault in the metering pump 3, it immediately sends the fault information to the staff's mobile APP via the wireless communication module, and simultaneously displays a fault prompt message on the information interaction interface.

[0039] The refrigeration unit 5 is a fully automatic control type product of model SC-100, with a cooling capacity of 100W, and is installed in the lower receiving cavity of the cabinet 1. The refrigeration unit 5 is connected to the interior of the cabinet 1 through a 10cm diameter air duct, and guide vanes are installed inside the air duct to ensure uniform temperature inside the cabinet 1. The refrigeration unit 5 consists of a compressor, condenser, evaporator, fan, etc. The compressor is a high-efficiency compressor of model QD75Y with a power of 120W; the condenser adopts a finned structure with a heat dissipation area of ​​0.5m²; the evaporator adopts a coil structure with an evaporation area of ​​0.3m²; and the fan is a 12cm diameter axial fan with an air volume of 300m³ / h.

[0040] The refrigeration unit 5 is equipped with a DS18B20 temperature sensor, which is installed at three different locations inside the cabinet 1 (upper, middle, and lower) to monitor temperature changes inside the cabinet 1 in real time. The temperature sensor transmits the temperature data to the control host 4 via a single bus. The control host 4 automatically controls the refrigeration unit 5 according to a preset temperature range (15℃-25℃). When the temperature inside the cabinet 1 exceeds 25℃, the control host 4 starts the refrigeration unit 5, the compressor begins working, and the fan operates to expel heat from the cabinet 1. When the temperature reaches 15℃, the control host 4 shuts down the refrigeration unit 5, stopping the cooling process, thereby ensuring that the liquor is stored under suitable temperature conditions and maintaining its quality.

[0041] The storage tank 12 is filled with inert gas (nitrogen). The inert gas cylinder 6 is a 10L high-pressure steel cylinder with an internal pressure of 15MPa. The inert gas cylinder 6 is connected to the storage tank via a copper pipe with an inner diameter of 0.5cm. A JQF-10 gas pressure sensor and a 2W-160-25 solenoid valve are installed on the copper pipe. The gas pressure sensor monitors the nitrogen pressure inside the cylinder in real time. When the nitrogen pressure is below 10MPa, the gas pressure sensor sends a signal to the control host 4. The control host 4 then controls the solenoid valve to open and starts the pneumatic pump 8, allowing nitrogen to be replenished from the external nitrogen cylinder. This ensures that the storage tank always has sufficient inert gas, preventing oxidation of the liquor and extending its shelf life.

[0042] The dispensing system includes a suction transmission assembly and a dispensing transmission assembly. The suction transmission assembly employs a multi-to-multi structure, consisting of twenty-four food-grade silicone tubes with an inner diameter of 0.8cm. Each tube serves as a dispensing tube, corresponding to one of the twenty-four storage tanks and inserted into the bottom of each tank to ensure complete extraction of the liquid. The other end of each dispensing tube corresponds to one of the twenty-four dispensing holes on the mixing device, connected via quick-connect fittings for easy disassembly and maintenance. The suction pump is a DP-10 miniature diaphragm pump with a flow rate of 10L / h, installed at the end of the suction pipeline near the storage tanks, enabling rapid and stable extraction of liquid and ensuring efficient dispensing.

[0043] The dispensing transmission assembly consists of a dispensing pipe, a dispensing valve, and other components. The dispensing pipe is a food-grade silicone hose with an inner diameter of 1 cm, connecting the metering pump 3 and the mixing container 7, and delivering the liquid pumped by the metering pump 3 to the mixing container 7. The dispensing valve is installed on the dispensing pipe and is a ZQDF-L15 electromagnetic flow control valve, connected to the control host 4 via a wire, enabling precise control of the liquid flow rate and direction according to the instructions of the control host 4.

[0044] The mixing container 7 is made of food-grade 304 stainless steel, and is cylindrical with a diameter of 40cm and a height of 50cm. Its large internal space allows for the mixing of various liquors. The mixing container 7 is equipped with a stirring device consisting of a 150W stirring motor, a 2cm diameter stirring shaft, and three blades. The stirring motor is installed at the top center of the mixing container 7 and connected to the stirring shaft via a coupling. A 30cm diameter, inclined-blade turbine-type stirring blade is mounted at the lower end of the stirring shaft, ensuring thorough mixing of the liquors within the container. Once the liquors enter the mixing container 7, the control unit 4 activates the stirring motor, which drives the stirring blades at 300rpm, achieving uniform mixing of the liquors within 30 seconds, ensuring a consistent and stable taste after mixing. The bottom of the mixing container 7 is provided with a circular outlet with a diameter of 3cm. The outlet is connected to the outlet on the front of the cabinet 1 through a food-grade silicone tube with an inner diameter of 1cm, so as to deliver the mixed liquor to the customer.

[0045] The workflow implementation method is as follows:

[0046] When a customer approaches the automatic wine vending machine, they operate it through the information interaction interface 11 on the front of the cabinet 1. The customer first selects the desired type of wine, such as Maotai-flavor liquor, then chooses the mixing ratio, for example, a 2:1 ratio of aged wine to new wine, and sets the purchase quantity to 300mL. After completing the selection, the customer makes the payment through the information interaction interface. Upon successful payment, the control host 4 receives the payment completion signal and immediately generates a wine vending control program. The customer can choose to pay to retrieve an empty wine bottle 13 provided in the cabinet 1, or bring their own container.

[0047] According to the liquor dispensing control program, the control host 4 sends an opening signal to the normally closed solenoid valves on the top of the corresponding aged liquor storage tank and the newly produced liquor storage tank, and the solenoid valves open rapidly. Simultaneously, the control host 4 sends a command to the metering pumps 3 corresponding to the two storage tanks, and the metering pumps 3 start to extract the liquor. According to the program settings, the metering pumps 3 precisely extract 200mL of liquor from the aged liquor storage tank and precisely extract 100mL of liquor from the newly produced liquor storage tank. The extracted liquor is then transported to the mixing container 7 through the suction pipe of the suction transmission assembly.

[0048] After the liquor enters the mixing container 7, the control host 4 activates the stirring device of the mixing container 7. The stirring motor drives the stirring paddle to rotate, thoroughly mixing the liquor. After mixing is complete, the control host 4 opens the outlet valve at the bottom of the mixing container 7 and the valve at the outlet on the front of the cabinet 1. The mixed liquor flows out through the outlet pipe from the outlet on the front of the cabinet 1 for customers to use.

[0049] Throughout the wine sales process, level sensors monitor the liquid level in the storage tanks in real time. When the liquid level in a tank falls below a preset value, the level sensor sends a warning message to the control host 4. The control host 4 then notifies the customer of the insufficient stock of that wine through an information interaction interface and sends a replenishment notice to the staff. Simultaneously, the door magnetic switch monitors the opening and closing status of the back cover door of the cabinet 1 in real time. If the back cover door is illegally opened, the door magnetic switch immediately sends a signal to the control host 4, which triggers an alarm device and records relevant information. The refrigeration unit 5 automatically adjusts its operation based on the internal temperature of the cabinet 1 monitored by the temperature sensor to ensure the wine storage environment meets requirements. The gas pressure sensor in the inert gas tank 6 monitors the nitrogen pressure in real time. When the pressure is insufficient, the control host 4 controls the solenoid valve to open, replenishing nitrogen and preventing oxidation of the wine.

[0050] The above examples are merely specific embodiments of this utility model. Obviously, this utility model is not limited to the above embodiments, and many similar modifications are possible. All variations that can be directly derived or conceived by those skilled in the art from the content disclosed in this utility model should be considered within the scope of protection of this utility model.
