Description

Technical Field

[0001] This utility model relates to the field of wine extractors, and in particular to a multi-person electric wine extractor. Background Technology

[0002] An electric wine dispenser is a device consisting of a motor, a pump, and a control circuit. It uses electricity to drive the pump to generate suction and extract wine. It has advantages such as easy operation, accurate wine dispensing, and reduced contact between wine and air. It is widely used in homes, bars, wineries, and other settings for automatic wine dispensing.

[0003] In the prior art, patent application number CN202221266923.8 discloses a digital display quantitative wine extractor, including a housing and an electric wine extraction component disposed inside the housing. The top of the housing has a main control panel, which includes a display screen and control buttons. The electric wine extraction component includes a main control circuit board, a power supply, a water pump, an air pump, and a micro switch. The added air pump enables a wine aeration function. A mechanical touch panel is located at the lower end of the water outlet. By using the micro switch and the mechanical touch panel, when the mechanical touch panel is detached from the water outlet, pressing it further inward activates the micro switch, starting the water pump. Conversely, releasing the touch panel stops the water pump. By accurately controlling the wine extraction flow rate, the error value of the extracted wine is kept within ±1%, thus achieving precise quantitative wine extraction.

[0004] However, the aforementioned technology uses a standalone dispensing device that is mounted on the bottle. When dispensing, the glass is not easily aligned, requiring the glass to be raised to receive the liquor, which is inconvenient. Furthermore, when multiple people are drinking together, the dispensing spout always faces the same direction, making it inconvenient for people sitting to the side or behind the spout to receive the liquor. They would need someone else to help them receive the liquor or manually adjust the spout to the appropriate position, which is quite troublesome. Utility Model Content

[0005] The main purpose of this invention is to propose a multi-person electric wine dispenser, which aims to solve existing technical problems.

[0006] To achieve the above objectives, this utility model proposes a multi-person electric wine dispenser, comprising a dispenser body, which includes a base, a support column, and a wine-drawing component. The support column is installed on the upper end of the base, and the wine-drawing component is fixedly connected to the support column. The base is provided with several cup holders, and the upper end of the support column is provided with a wine outlet for pouring wine into the cups on the cup holders. Each cup holder is provided with a wine sensor, and the dispenser body is also provided with a rotating component that rotates the wine outlet. When a wine glass is detected on one of the cup holders, the rotating component controls the wine outlet to rotate to the corresponding position to pour wine.

[0007] This invention can automatically pour wine for users in various positions of the wine dispenser. Simply place the wine glass on the corresponding cup holder, and the rotating component will automatically rotate to turn the wine outlet above the corresponding cup holder to pour the wine into the glass.

[0008] Preferably, a plurality of the cup holders are arranged in a ring around the support column.

[0009] The equidistant arrangement of the glass holder and support column ensures that the spout can rotate directly above each glass holder without deviation, preventing leakage.

[0010] Preferably, the rotating assembly includes a rotating column and a drive motor. The rotating column is rotatably connected to the top of the support column, and the drive motor is fixedly installed on the upper end of the support column. The rotating column and the drive motor are driven to rotate the rotating column.

[0011] By controlling the motor to drive the rotating column to rotate, the wine outlet is rotated to the corresponding position.

[0012] Preferably, a positioning element is provided on one side of the rotating column, and a plurality of sensors are evenly provided on the upper circumference of the support column for sensing the positioning element and determining the rotation angle of the wine outlet.

[0013] Sensors and positioning devices can detect the exact angle to which the water outlet rod has rotated, thereby determining its position.

[0014] Preferably, the positioning element is a magnet, and the sensor is a Hall sensor.

[0015] The rotation position of the rotating column is further determined by Hall effect sensors and magnets, so that it can be precisely rotated above the glass holder where the wine needs to be poured.

[0016] Preferably, the body of the wine extractor is provided with a horizontal fixing rod, one end of which is fixedly connected to the rotating end of the rotating assembly, and the wine outlet is located at the end of the horizontal fixing rod opposite to the rotating assembly.

[0017] By using a horizontal fixing rod, the distance between the wine spout and the support column is made the same as the distance between the cup base and the support column, so that the wine spout can be rotated to be directly above the cup base for easy pouring.

[0018] Preferably, the base is provided with a wine extraction hose, which is inserted into the base and fixedly connected to the water-absorbing end of the wine extraction component. The other end of the wine extraction hose is used to insert into the wine bottle to extract wine.

[0019] By connecting the wine bottle and the wine extraction assembly with a wine extraction hose, there is no need to install the wine extractor body directly on the bottle mouth. This allows the height of the wine outlet to be set at an appropriate position, preventing wine from splashing out of the glass when pouring due to the outlet being too high.

[0020] Preferably, a display screen is provided at one end of the base.

[0021] The dispensing volume and on / off function can be set via the display screen.

[0022] Preferably, one end of the base is provided with an interface for charging and data transmission.

[0023] The interface allows the wine dispenser to be charged and can also be connected to other gaming peripherals, such as electric Gomoku, Monopoly, and Tetris. It can automatically dispense wine to the winner or loser according to the rules of different games, increasing the entertainment value.

[0024] The technical solution of this utility model has the following beneficial effects: By setting multiple cup holders on the base, this utility model can accommodate people located in different directions from the wine dispenser. Sensors on the cup holders detect whether there is a wine glass on the holder. The wine outlet is rotated to the corresponding position by a rotating component to dispense wine. Users can place the wine glass in any cup holder, and the wine dispenser automatically rotates the wine outlet to pour the wine. There is no need to pick up the wine glass, align it with the wine outlet, or manually rotate the wine outlet to the corresponding direction, which is convenient, fast, and improves the user experience.

[0035] This utility model proposes a multi-person electric wine dispenser.

[0036] like Figures 1 to 2 As shown in one embodiment of this utility model, a multi-person electric wine dispenser includes a dispenser body, which includes a base 1, a support column 3, and a wine-drawing component 9. The support column 3 is installed on the upper end of the base 1, and the wine-drawing component 9 is fixedly connected to the support column 3. The base 1 is provided with several cup holders 2, which are used to identify and fix wine glasses. The upper end of the support column 3 is provided with a wine outlet 5 for pouring wine into the wine glasses on the cup holder 2. Each cup holder 2 is provided with a wine glass sensor, which senses whether there is a wine glass on the cup holder 2. The dispenser body is also provided with a rotating component 4 that rotates the wine outlet 5. When a wine glass is sensed on one of the cup holders 2, the rotating component 4 controls the wine outlet 5 to rotate to the corresponding position to pour wine.

[0037] This embodiment, by setting multiple cup holders 2 on the base 1, can accommodate people located in different directions from the wine dispenser. Sensors on the cup holders 2 detect whether there is a wine glass on the cup holder 2. The wine outlet 5 is rotated to the corresponding position by the rotating component 4 to dispense wine. This allows users to place the wine glass in any cup holder 2, and the wine dispenser automatically rotates the wine outlet 5 to pour the wine. There is no need to pick up the wine glass, align it with the wine outlet 5, or manually rotate the wine outlet 5 to the corresponding direction, which is convenient, quick, and improves the user experience.

[0038] The height distance between the wine outlet 5 and the base 1 is not limited. To prevent the wine outlet 5 from being too high above the wine glass on the glass holder 2, which could cause the wine to splash easily, the height of the wine outlet 5 can be set 5 cm above the top of the wine glass on the glass holder 2. This effectively prevents the wine from splashing and does not affect the placement and removal of the wine glass. The wine extraction component 9 uses a water pump and is fixedly installed on the support column 3. The glass holders 2 are evenly distributed in various positions on the base 1, and their positions are not limited. The wine can be poured into the corresponding glass by controlling the water output of the wine outlet 5 and the rotating component 4. The rotating component 4 can be set at various positions on the rotating column 42, without limitation. It can be in the middle, bottom, or top. The structure includes a drive motor 41 and a rotating column 42. The rotating column 42 can be directly driven to rotate by gears. The system can be driven by a lead screw, or the rotating column 42 can be directly installed at the output end of the drive motor 41, which will not be elaborated on here. The sensor can be one of the following: a capacitive sensor, which determines the presence of an object by detecting the change in capacitance between the object and the sensor, and is effective for both metal and non-metal objects; an inductive sensor, which is based on electromagnetic induction when metal is added to the wine glass, and is only sensitive to metal objects, triggering a signal by the magnetic field disturbance caused by the metal approaching; an ultrasonic sensor, which emits ultrasonic waves and receives reflected signals, and calculates the distance by the time difference; and an infrared / photoelectric sensor, which uses the object to block or reflect infrared / visible light to trigger a change in the signal of the photosensitive element. A PCB board is installed on the base 1 to control the wine extraction component 9, thereby controlling the flow rate and amount of wine at the wine outlet 5, and controlling the rotating component 4 to rotate to the corresponding position.

[0039] Furthermore, the wine extractor body consists of a base 1, a support column 3, and a wine extraction component 9. The base 1 has six cup holders 2 on its surface, each cup holder 2 having a pressure sensor embedded in its bottom as a wine glass sensor. A rotatable wine outlet 5 is installed on the top of the support column 3, and the wine outlet 5 is driven by a rotating component 4. When a cup holder 2 detects the weight of a wine glass (e.g., >100g), the rotating component 4 rotates the wine outlet 5 to be directly above that cup holder 2, and the wine extraction component 9 starts pouring wine. The wine glass sensor is not limited to a pressure sensor; it can be replaced with an infrared photoelectric sensor (detecting glass obstruction) or a capacitive proximity switch (detecting metal wine glasses). The rotating component 4 can include gear transmission, belt transmission, or direct motor drive to achieve the rotation of the wine outlet 5. During family gatherings, users can place multiple wine glasses on different cup holders 2, and the wine extractor will automatically fill them with red wine sequentially. Alternatively, individual wine glasses can be placed on their corresponding cup holders 2 without manual operation or adjustment of the wine outlet 5's direction.

[0040] Preferably, a number of cup holders 2 are arranged in a ring around the support column 3. By equidistantly arranging the cup holders 2 and the support column 3, the wine outlet 5 can be rotated to be directly above each cup holder 2 without deviation, thus preventing the wine from leaking out.

[0041] Optionally, the base 1 is made of sturdy engineering plastic, providing sufficient weight and stability to support the entire wine-drawing device. A threaded hole matching the thread of the support column 3 is drilled in the center of the base 1 for mounting the support column 3. The support column 3 is made of metal, such as stainless steel, to ensure its strength and durability. One end of the support column 3 is machined with external threads, allowing it to tightly engage with the threaded hole in the center of the base 1 for secure fixing. The height of the support column 3 is determined according to actual design requirements, ensuring that the wine glasses placed on the glass holder 2 can smoothly receive the wine while also considering the overall aesthetics and spatial layout of the device. The glass holder 2 is also made of engineering plastic and designed with a groove structure that conforms to the shape of the bottom of common wine glasses to ensure stable placement of the glasses. Six glass holders are evenly distributed at angles around the support column 3 in the glass holder 2. For precise positioning, corresponding glass holders are mounted on the base 1. A positioning groove is machined at position 2, and a positioning protrusion matching the positioning groove is set at the bottom of the cup holder 2. During installation, the cup holder 2 is embedded into the positioning groove to ensure its positional accuracy. A miniature diaphragm pump is selected as the wine extraction component 9. The miniature diaphragm pump has the advantages of small size, low noise, and good sealing performance, which is suitable for the needs of this wine extraction device. The miniature diaphragm pump is fixed on a suitable bracket, which is connected to the base 1 by screws or clips to ensure that the pump body is firmly installed. The liquid inlet of the pump body is connected to a liquid-resistant suction tube for inserting into the wine container to extract the liquid. The liquid outlet is connected to the wine outlet 5 component through a flexible wine outlet tube. The wine outlet 5 is designed as a rotatable structure and is installed on a device connected to the drive motor 4. On the rotating disk connected to the output shaft, the rotating disk is mounted on a fixed bracket via bearings to ensure smooth rotation. The wine outlet 5 is shaped like a long, narrow nozzle to accurately inject the wine into the glass. A flow control valve is installed near the wine outlet 5, which can adjust the flow rate and volume of the wine via a control circuit. A wine glass sensor is installed at an appropriate position on each glass holder 2, such as an infrared sensor or a capacitive sensor. The infrared sensor detects the presence of the wine glass by detecting whether it blocks infrared light, while the capacitive sensor detects the change in capacitance when the wine glass approaches. The wine glass sensor is connected to the control circuit via wires, transmitting the detection signal to the control circuit. The drive motor 41 is selected. A stepper motor serves as the power source for rotating the wine outlet 5. The stepper motor features high control precision and the ability to accurately control the rotation angle. The stepper motor is fixed in a suitable position on the base 1, and the output shaft of the motor is connected to the central shaft of the rotating disk through a coupling to ensure that the motor can drive the rotating disk and the wine outlet 5 to rotate accurately when it rotates. A control circuit based on a microcontroller (such as a single-chip microcomputer) is designed. The main function of the control circuit is to receive the signal from the wine glass sensor, determine which glass holder 2 is placed on the glass based on the signal, and control the drive motor 41 to rotate the wine outlet 5 by 60° to align it with the glass holder 2. At the same time, the control circuit is also responsible for communicating with the flow control valve to adjust the flow rate of the wine.The power module provides a stable power supply for the entire device. An AC-to-DC power adapter can be used to convert AC mains power into DC voltage suitable for the operation of the electronic components. The power module uses a voltage regulator circuit to regulate the output voltage, ensuring that all components operate within the normal voltage range. The software program design includes an initialization program that initializes the various ports, timers, interrupts, and other functions of the microcontroller during system startup. It initializes the detection mode of the wine glass sensors, sets the initial position of the drive motor 41, and sets the control parameters of the stepper motor, such as step angle and speed. The detection program continuously monitors the status of each wine glass sensor through a cyclic scanning method. When a change in the signal of a wine glass sensor is detected (indicating a wine glass is placed on the corresponding glass holder 2), the number of the glass holder 2 is recorded, and the rotation control program is triggered. The rotation control program calculates the required rotation angle of the dispensing spout 5 based on the detected glass holder 2 number (60° rotation each time). By controlling the pulse signal of the stepper motor, the rotation angle of the stepper motor is precisely controlled, causing the rotating disk to accurately align the dispensing spout 5 with the glass holder 2. During rotation, an appropriate delay can be added to ensure smooth rotation. Dispensing control program: When the dispensing spout 5 is aligned with the glass, the control circuit sends a command to the flow control valve, opening the valve and adjusting the flow rate and volume of the liquid according to preset flow parameters to achieve automatic dispensing. During dispensing, the status of the glass sensor can be monitored in real time. If the glass is detected to have left the glass holder 2, the flow control valve is immediately closed, stopping the dispensing.

[0042] Preferably, such as Figure 2 As shown, the rotating assembly 4 includes a rotating column 42 and a drive motor 41. The rotating column 42 is rotatably connected to the top of the support column 3. The rotating column can be inserted into or sleeved on the top of the support column 3 and rotatably connected to the support column 3. The drive motor 41 is fixedly installed on the upper end of the support column 3. The rotating column 42 is driven by the drive motor 41 to rotate the rotating column 42. By controlling the motor to drive the rotating column 42 to rotate, the wine outlet 5 is driven to rotate to the corresponding position.

[0043] Furthermore, the rotating assembly 4 includes a vertical rotating column 42 and a stepper motor; the rotating column 42 is connected to the top of the support column 3 via a bearing, and the stepper motor is fixed inside the support column 3 and drives the rotating column 42 to rotate via a coupling; the stepper motor receives a control signal and rotates precisely to the target angle (e.g., 1.8° per step, 200 steps / revolution); after detecting the wine glass, the controller calculates the angle of the target glass holder 2 and drives the stepper motor to rotate the corresponding number of steps, with an error of <±0.5°.

[0044] In addition, the drive motor 41 can be replaced with a servo motor (higher precision) or a DC geared motor (low-cost solution); the transmission method can be changed to a gear set (such as a 20:1 reduction gear) to increase torque.

[0045] Preferably, such as Figure 3 As shown, a positioning element is provided on one side of the rotating column 42, and several sensors are evenly provided on the upper circumference of the support column 3 to sense the positioning element and determine the rotation angle of the outlet 5. Through the sensors and positioning element, the angle to which the water outlet rod has rotated can be sensed, thereby determining the position of the water outlet rod.

[0046] Furthermore, the positioning element can be designed as a small metal block or magnetic block with obvious identifiable features to work in conjunction with the sensor. For example, if a magnetic positioning element is selected, a neodymium iron boron magnet 43 can be used, which has strong magnetism and can ensure reliable sensor sensing. The positioning element is installed on the side surface of the rotating column 42 near the support column 3. To ensure that the positioning element is firmly installed and does not affect the normal rotation of the rotating column 42, high-strength adhesive can be used for bonding, or a groove adapted to the shape of the positioning element can be opened on the rotating column 42. After the positioning element is embedded in the groove, it is fastened with screws or other fixing methods. The positioning element should be installed at the height position corresponding to the sensor on the support column 3 to ensure accurate sensing by the sensor. A suitable sensor is selected according to the nature of the positioning element. If the positioning element is a metal block, an inductive proximity sensor can be selected, which uses the principle of electromagnetic induction and can generate a sensing signal when a metal object approaches. If the positioning element is a magnetic block, a Hall sensor is selected. The device can sense changes in the magnetic field and output corresponding electrical signals. Several sensors are evenly distributed around the upper circumference of the support column 3. The number of sensors is determined by the required accuracy of the rotation angle. For example, if it is desired to accurately determine every 10° of rotation angle, since the circumference is 360°, at least 36 sensors are needed. Mounting holes or slots are machined on the support column 3 corresponding to the sensor mounting positions. After the sensors are embedded in the mounting holes or slots, they are fixed with screws or glue. The sensing surface of the sensor should face the positioning component to ensure effective sensing of changes in the positioning component's position. Simultaneously, to protect the sensors from external environmental influences, a protective shell can be added to the outside of the sensors. The protective shell is made of a transparent and insulating material, such as plexiglass, which does not affect sensor sensing and provides dust and moisture protection. All sensor signal output terminals are connected to a signal processing circuit via wires. Shielded wires should be selected to reduce the impact of external electromagnetic interference on the sensor signals. The signal processing circuit can be integrated onto a printed circuit board (PCB), which is installed inside or near the support column 3 in a suitable location and secured with screws or clips. The signal processing circuit mainly consists of signal amplification, shaping, and encoding circuits. The weak signal output from the sensor is first amplified by the signal amplification circuit for subsequent processing. The amplified signal is then converted into a standard digital signal, such as a square wave signal, by the shaping circuit. The encoding circuit encodes the rotation angle of the rotating column 42 according to the sequence and combination of different sensor output signals. The encoded signal is transmitted to a microcontroller (such as a single-chip microcomputer) for processing. The microcontroller pre-stores a correspondence table between sensor signals and rotation angles. Upon receiving the encoded signal, the microcontroller determines the rotation angle of the outlet 5 based on the correspondence table, thereby determining the position of the outlet 5. The microcontroller can transmit the angle and position information to other devices, such as the display screen 7, via serial communication or wireless communication, so that operators can intuitively understand the position status of the outlet 5.

[0047] Preferably, the positioning element is a magnet 43 and the sensor is a Hall sensor 44. The rotation position of the rotating column 42 is further determined by the Hall sensor and the magnet 43 so as to accurately rotate it above the glass holder 2 where wine needs to be poured.

[0048] Preferably, such as Figure 4 As shown, the body of the wine dispenser is provided with a horizontal fixing rod 10. One end of the horizontal fixing rod 10 is fixedly connected to the rotating end of the rotating component 4. The wine outlet 5 is located at the end of the horizontal fixing rod 10 away from the rotating component 4. The horizontal fixing rod 10 makes the distance between the wine outlet 5 and the support column 3 the same as the distance between the cup base 2 and the support column 3, so that the wine outlet 5 can rotate to be directly above the cup base 2, which is convenient for pouring wine.

[0049] Preferably, the base 1 is provided with a wine extraction hose 6, which is inserted into the base 1 and fixedly connected to the water absorption end of the wine extraction component 9. The other end of the wine extraction hose 6 is used to insert into the wine bottle to extract wine. By connecting the wine bottle and the wine extraction component 9 through the wine extraction hose 6, it is not necessary to install the wine extractor body directly on the mouth of the wine bottle. This allows the height of the wine outlet 5 to be set at an appropriate position, avoiding the wine from splashing out of the glass when pouring wine due to the wine outlet 5 being too high.

[0050] Preferably, one end of the base 1 is provided with a display screen 7, which can be used to set the amount of alcohol dispensed and the power on / off function.

[0051] The display screen 7 is selected from either a liquid crystal display (LCD) or an organic light-emitting diode display (OLED). These two types of displays offer advantages such as low power consumption, small size, and clear display. For example, a segment LCD display 7 can be selected for simple number and character display needs, while a dot-matrix LCD or OLED display 7 can be used for displaying richer graphics and text information. A suitable groove is pre-drilled at one end of the base 1 for mounting the display screen 7. The groove's dimensions precisely match the display screen 7's casing to ensure a stable installation. The display screen 7 is fixed in the groove using screws or glue. The display surface of the display screen 7 should be flush with the surface of the base 1 for easy viewing and operation. Control circuit: The main control chip is a suitable microcontroller (MCU), such as the common Arduino series chips or STM32 series chips. These chips have abundant peripheral interfaces 8, which can meet the communication needs with the display screen 7, buttons, and other functional modules of the wine dispenser; the button circuit has several function buttons installed on the base 1 near the display screen 7, such as "Set", "Increase", "Decrease", "Confirm", "Power On / Off" buttons, etc. Each button is connected to a GPIO (General Purpose Input / Output) pin of the MCU at one end and grounded at the other end. When the button is pressed, the level of the corresponding GPIO pin will change, and the MCU will identify the button operation by detecting the change in the pin level; the power supply circuit is designed to provide a stable power supply for the entire system, which will regulate and filter the external input power (such as the DC voltage output from the AC-DC adapter) to provide a suitable operating voltage for the MCU, display screen 7, and other circuit modules; the communication circuit, if the display screen 7 and the MCU use serial communication (such as SPI, I2C, etc.), then a corresponding communication interface 8 circuit needs to be designed in the circuit to connect the communication pin of the MCU with the corresponding pin of the display screen 7. Ensure the electrical characteristics of the communication lines meet standards. For example, SPI communication requires correct connection of the clock line (SCK), master output / slave input line (MOSI), master input / slave output line (MISO), and slave select line (SS). For dispensing control, the MCU connects to the dispensing component 9 (such as the drive circuit of a miniature diaphragm pump) via control pins. After the user sets the dispensing volume on the display screen 7, the MCU calculates the required dispensing time or pump operation count based on the set value and sends corresponding control signals to the drive circuit of the dispensing component 9 to precisely control the dispensing volume. For power switch control, the power button is connected to the MCU's GPIO pins. When the power button is pressed, the MCU detects the button signal and controls a relay or power MOSFET to turn the power supply on or off of the entire dispensing device, thus achieving the power on / off function.

[0052] Preferably, one end of the base 1 is provided with an interface 8 for charging and data transmission. The wine dispenser body can be charged through the interface 8, and other game peripherals can also be connected, such as electric Gomoku, Monopoly, Russian Roulette and other peripheral game devices. According to the rules of different games, the wine can be automatically dispensed to the winner or loser, increasing the entertainment value.

[0053] The interface 8 uses a multi-functional USB-Type C interface, which supports reversible insertion, high-speed data transmission, and high-power charging, meeting the needs of charging and connecting various gaming peripherals. A hole for the USB-Type C interface 8 is made at a suitable position on one end of the base 1, and the interface 8 module is embedded in it and fixed with screws or glue to ensure that the interface 8 is stable and easy to use. For the charging circuit, the charging management chip is a TP4056, which can achieve constant current and constant voltage charging management of the lithium battery. The input pin of the charging management chip is connected to the power pin of the USB-Type C interface 8, responsible for processing the external power input to charge the battery inside the wine dispenser. An 18650 lithium battery is selected to power the wine dispenser. The positive and negative terminals of the lithium battery are connected to the output pin of the charging management chip through a protection circuit. The protection circuit prevents overcharging, over-discharging, and short circuits, extending battery life and ensuring safe use. For the data transmission and control circuit, the main control chip is an STM32F4 series microcontroller (MCU), which has rich peripheral interfaces, including multiple USB interfaces and GPIO. The system includes ports and high-speed timers to meet the data interaction requirements with game peripherals and the control requirements of the alcohol dispenser. USB data processing connects the data pins of the USB-Type C interface 8 to the MCU's USB peripheral interface 8. When a game peripheral is connected, the MCU communicates with it via the USB protocol, identifies the peripheral type, and receives game result data (such as win / loss information). Based on the received game result data, the MCU outputs control signals through GPIO ports to drive the alcohol dispenser component 9 (such as a miniature diaphragm pump), automatically dispensing alcohol to the winner or loser. Simultaneously, a solenoid valve can be controlled to precisely control the flow of alcohol, ensuring that the amount dispensed each time meets the set requirements. Considering that different game peripherals may use different data communication protocols, a protocol conversion circuit is designed or the protocol conversion function is implemented in software. For example, for game peripherals using Bluetooth communication, a Bluetooth module can be added, and a corresponding driver can be written to convert Bluetooth data into a format that the MCU can recognize.

[0054] Specifically, the working principle and usage process of this utility model are as follows: By setting multiple cup holders 2 on the base 1, it can accommodate people located in different directions from the wine dispenser. Sensors are set on the cup holders 2 to detect whether there is a wine glass on the cup holder 2.
