Example implementations may, however, be implemented in many different forms and should not be construed as limited to the examples set forth herein; rather, these implementations are provided so that this disclosure will be thorough and complete, and will fully convey the scope of example implementations to those skilled in the art. The described features, structures, or characteristics can be combined in one or more implementations. In the following description, numerous specific details are provided to give a thorough understanding of implementations of the claimed subject matter.

[0045] The vending machine is a common device for commercial automation, which is not limited by time and place, can save manpower and facilitate transactions. It is a new form of commercial retail, also known as a 24-hour operating micro-supermarket. However, the automatic water vending machines currently widespread in various communities can only provide pure water, and users need to provide their own water buckets, which has limitations. The business needs to sell water cards, water buckets, etc. and needs to find another place to organize personnel, etc. Users cannot purchase water cards, water buckets or other needs in time, which affects the experience. And the distribution of automatic vending machines is mainly concentrated in places with a large number of people such as shopping malls and scenic spots, and the distribution is not extensive enough.

[0046] To solve the above problems, an apparatus for expanding the vending function of a water vending machine is provided, as shown in Figures 1-3 The apparatus includes a main board 10, a communication adapter board 20, an electromagnetic lock 30, and a status indicator light 40. The main board 10 includes a communication input 11, an electromagnetic lock control output 12, and a status indicator light control output 13. The input end of the communication adapter board 20 is connected to the output end of the main board of the water vending machine, and the output end of the communication adapter board 20 is connected to the communication input 11 to transmit data information of the main board of the water vending machine to the main board 10. The main board 10 receives data information and processes to obtain a control signal, which includes an electromagnetic lock control signal and a status indicator light control signal.

[0047] The main board 10 serves as the core control unit of the apparatus, responsible for receiving, processing, and outputting control signals. It is equipped with a communication input 11, an electromagnetic lock control output 12, and a status indicator light control output 13. The communication input 11 is used to receive data information from the main board of the water vending machine, which includes but is not limited to user-selected product instructions, product inventory status, etc. After processing these information, the main board 10 will generate corresponding control signals.

[0048] The input end of the communication adapter 20 is connected with the output end of the vending machine mainboard, ensuring that the data information generated by the vending machine mainboard can be accurately transmitted to the mainboard 10. At the same time, the output end of the communication adapter 20 is connected with the communication input end 11 of the mainboard 10, thereby realizing bidirectional transmission of data.

[0049] The input end of the electromagnetic lock 30 is connected with the electromagnetic lock control output end 12, and the electromagnetic lock 30 is used for receiving the electromagnetic lock control signal sent by the mainboard 10 after receiving, and opening or closing the goods channel according to the electromagnetic lock control signal.

[0050] The electromagnetic lock 30 is used for controlling the opening or closing of the goods channel, and the input end of the electromagnetic lock 30 is connected with the electromagnetic lock control output end 12 of the mainboard 10 to receive the electromagnetic lock control signal from the mainboard 10. When the mainboard 10 receives the instruction of selecting goods by the user and confirms the successful transaction, an opening signal will be sent to the electromagnetic lock 30 to unlock the corresponding goods channel and allow the goods to be taken out. Conversely, when the goods channel needs to be closed, the mainboard 10 will send a closing signal to the electromagnetic lock 30.

[0051] The input end of the status indicator 40 is connected with the status indicator control output end 13, and the status indicator 40 is used for receiving the status indicator control signal sent by the mainboard 10 after receiving, and lighting or extinguishing according to the status indicator control signal.

[0052] The status indicator 40 is used for providing real-time device status information. The input end of the status indicator 40 is connected with the status indicator control output end 13 of the mainboard 10 to receive the status indicator control signal from the mainboard 10. These signals include the goods inventory status (such as out of stock, sufficient, etc.) and the device running status (such as normal work, fault, etc.). The status indicator 40 displays the device status by lighting or extinguishing according to the received signal, which facilitates the user or the management personnel to quickly understand the device condition.

[0053] The vending machine device provided by the embodiment of the present application successfully expands the function of the vending machine from single water vending to vending, which improves the practicability and market competitiveness of the device. The user can not only purchase drinking water on the vending machine, but also can choose to purchase other matching goods, meeting more diversified needs. Through the intelligent processing of the mainboard 10, the device can realize accurate control of the electromagnetic lock 30 and the status indicator 40. Such intelligent control not only improves the automation degree of the vending process, but also reduces the error and failure rate caused by human operation. The real-time display function of the status indicator 40 enables the user to clearly understand the status information of the device, thereby making a more intelligent choice. At the same time, the fast response and accurate control of the electromagnetic lock 30 also ensure that the user can quickly and smoothly obtain the required goods.

[0054] In summary, the device for expanding the vending function of the water vending machine provided by the embodiments of the present application has remarkable beneficial effects in function expansion, intelligent control, user experience, and maintenance convenience, and meets the needs of users for diversified goods, improves the intelligent level and reliability of the equipment, and provides an effective solution for upgrading and reconstruction of the water vending machine.

[0055] In some embodiments of the present application, referring to Figure 4 As shown in the figure, the electromagnetic lock control signal includes: the number of the goods channel, the goods channel closing signal and the goods channel opening signal; when the electromagnetic lock 30 receives the number of the goods channel and the goods channel closing signal, the electromagnetic lock 30 corresponding to the number of the goods channel is closed; when the electromagnetic lock 30 receives the number of the goods channel and the goods channel opening signal, the electromagnetic lock 30 corresponding to the number of the goods channel is opened; the status indicator lamp control signal includes: the number of the goods channel, the goods shortage signal and the goods sufficient signal; when the status indicator lamp 40 receives the number of the goods channel and the goods shortage signal, the status indicator lamp 40 corresponding to the number of the goods channel is extinguished; when the status indicator lamp 40 receives the number of the goods channel and the goods sufficient signal, the status indicator lamp 40 corresponding to the number of the goods channel is lighted. It can be understood that the actual number of the sixteen-way electromagnetic lock and the sixteen-way status indicator lamp used in the embodiment is not limited by the present application.

[0056] The electromagnetic lock 30 obtains the electromagnetic lock control signal from the mainboard 10, including the number of the goods channel, the goods channel closing signal and the goods channel opening signal. When the mainboard 10 obtains the instruction containing the specific number of the goods channel and the goods channel closing signal from the mainboard of the water vending machine, the electromagnetic lock 30 identifies and responds to these signals, closes the lock corresponding to the number of the goods channel, and ensures that the goods are safely locked when not needed. Conversely, when receiving the instruction containing the number of the goods channel and the goods channel opening signal, the electromagnetic lock 30 unlocks the corresponding goods channel to allow customers to take out the goods.

[0057] The status indicator lamp 40 obtains the status indicator lamp control signal from the mainboard 10, including the number of the goods channel, the goods shortage signal and the goods sufficient signal. When the mainboard 10 obtains the data information of the insufficient inventory of the goods in a certain goods channel from the mainboard of the water vending machine, and sends the instruction containing the number of the goods channel and the goods shortage signal, the status indicator lamp 40 of the corresponding goods channel is extinguished, informing the customers or the management personnel that the goods channel needs to be restocked. If the goods in a certain goods channel are sufficient, the system sends the instruction containing the number of the goods channel and the goods sufficient signal, and the status indicator lamp 40 of the corresponding goods channel is activated, indicating that the goods in the goods channel can be selected and purchased.

[0058] Through the precise control of the electromagnetic lock 30, it is ensured that only when the customer chooses to purchase, the corresponding commodity aisle will be unlocked, effectively preventing the disorderly access of goods and potential theft behavior. At the same time, the real-time feedback mechanism of the status indicator light 40 enables customers and management personnel to quickly identify which aisles need to be restocked, so as to take timely action and reduce sales losses due to out-of-stock. The intuitive display of the status indicator light 40 provides clear shopping guidance for customers, avoiding the time wasted in searching for goods. In addition, the instant response of the electromagnetic lock also improves the convenience and satisfaction of shopping.

[0059] For the management personnel, by monitoring the state of the status indicator light 40, the inventory can be more efficiently managed, the restocking plan can be reasonably arranged, and the labor cost and time cost can be reduced. At the same time, the integrated control system of the electromagnetic lock and the status indicator light also makes it possible to realize remote monitoring and automated management.

[0060] In some embodiments of the present application, a connection line is also included, one end of the connection line is connected to the output end of the mainboard 10, the other end is connected to the input end of the electromagnetic lock 30 and / or the input end of the status indicator light 40; the connection line is used to receive the control signal sent by the mainboard 10 and transmit the control signal to the electromagnetic lock 30 and the status indicator light 40.

[0061] The connection line as a signal transmission medium is connected to the input end of the electromagnetic lock 30 and the input end of the status indicator light 40 respectively, ensuring that the control signal sent by the mainboard 10 can be accurately and correctly transmitted to the target device. The introduction of the connection line makes the connection between the mainboard 10 and the electromagnetic lock 30 and the status indicator light 40 more stable and efficient, reduces the failure rate caused by poor signal transmission or loose connection, and thus improves the reliability and stability of the entire vending machine system. The flexible design and use of the connection line enable the mainboard 10 to control multiple electromagnetic locks 30 and status indicator lights 40 at the same time, maximizing the use of resources. This design not only improves the vending efficiency of the vending machine, but also reduces the hardware cost and maintenance cost.

[0062] In some embodiments of the present application, referring to Figure 5 It is shown that the communication adapter plate 20 is a 485 communication adapter plate, and the connection line is a 4p interface shielded line.

[0063] Specifically, the 485 communication adapter board is a hardware device used to realize the conversion between different serial communication interfaces. Its main function is to realize the conversion between RS-485 signals and other types of signals (such as RS-422). This allows remote data communication between computers, external devices or intelligent instruments equipped with different standard serial interfaces. The 485 communication adapter board supports high data transmission rates, typically up to 0-115.2KBPS, which can meet the needs of most application scenarios. It has electrical isolation technologies such as optoelectronic isolation to prevent equipment damage or communication failure caused by electrical interference or short circuits.

[0064] The 4p interface shielded cable is a shielded cable with four pins, two of which are used to transmit differential signals (positive and negative lines), and the other two are usually used for grounding or backup. The shielding layer is used to reduce the impact of external electromagnetic interference on signal transmission. The 4p interface shielded cable not only can carry the transmission tasks of electromagnetic lock control signals and status indicator light control signals, but also can provide sufficient shielding effect to ensure the integrity and accuracy of these key signals during transmission.

[0065] By using the 485 communication adapter board and the 4p interface shielded cable, the signal transmission stability of the vending machine device scheme has been significantly improved. The differential signal transmission method effectively reduces the impact of external electromagnetic interference on the signal, and the shielding layer further enhances the signal's anti-interference ability. The 485 communication adapter board supports long-distance and multi-node communication requirements, allowing the vending machine to connect more external devices (such as electromagnetic locks, status indicator lights, etc.) and perform stable communication within a larger space. This provides more possibilities for the expansion and upgrade of the vending machine. The use of the 4p interface shielded cable simplifies the wiring work and reduces the number and complexity of cables. The introduction of the 485 communication adapter board and the 4p interface shielded cable further improves the vending machine device scheme of the present application, making the entire system more stable, efficient and easy to manage.

[0066] In some embodiments of the present application, referring to Figure 6 The mainboard 10 also includes a power input terminal, a power output terminal and a transformer. The transformer includes a transformer input terminal and control power output terminals and status indicator light power output terminals. The power input terminal is connected to an external 220V AC power source, and the power output terminal is connected to the transformer input terminal. The transformer is used to step down the external 220V AC power source to obtain 12V stabilized output power and 5V stabilized output power. The control power output terminal is connected to the input terminal of the electromagnetic lock 30, and outputs 12V stabilized output power to the electromagnetic lock 30. The status indicator light power output terminal is connected to the input terminal of the status indicator light 40, and outputs 5V stabilized output power to the status indicator light 40.

[0067] The transformer inside is subjected to voltage reduction processing, converting a 220V alternating power supply into two kinds of stabilized output power supply, 12V and 5V. Among them, the 12V stabilized output power supply is connected to the input end of the electromagnetic lock 30 through the control power supply output end, providing stable and sufficient power supply for it; while the 5V stabilized output power supply is connected to the input end of the state indicating lamp 40 through the state indicating lamp power supply output end, ensuring that the indicating lamp can work normally and accurately reflect the state of the vending machine.

[0068] By introducing the transformer and multiple stabilized output design, the mainboard 10 can efficiently manage the power supply, providing stable and adaptive power supply for the electromagnetic lock 30 and the state indicating lamp 40. This not only reduces energy waste, but also improves the operation efficiency and stability of the entire vending machine device. The design of 12V and 5V two kinds of stabilized output power supply makes the mainboard 10 compatible with more types of external devices, such as different models of electromagnetic locks and state indicating lamps. This provides more possibilities for customization and upgrading of vending machines, meeting the application requirements in different scenarios.

[0069] In some embodiments of the present application, continuing to refer to Figure 1 As shown in the figure, the mainboard 10 also includes an electromagnetic lock state receiving end 14, which is connected with the output end of the electromagnetic lock 30 through a connecting line; the output end of the electromagnetic lock 30 is used to feed back the state of the goods channel to the mainboard 10, and the state of the goods channel includes: goods channel closed and goods channel opened.

[0070] It can be understood that the main function of the electromagnetic lock state receiving end 14 is to receive the goods channel state signal from the electromagnetic lock 30, including two states of goods channel closed and goods channel opened. The mainboard 10 can understand the occupancy of the goods channel inside the vending machine in real time according to the received signal, so as to carry out corresponding processing or control.

[0071] By adding the electromagnetic lock state receiving end 14, the mainboard 10 can receive the feedback signal from the electromagnetic lock 30 in real time, so as to understand the goods channel state of the vending machine in real time. This greatly improves the real-time performance and response speed of the system.

[0072] In some embodiments of the present application, referring to Figure 1 and Figure 7 As shown in the figure, the mainboard 10 also includes an expansion nixie tube interface 15, which is connected with an expansion nixie tube 50, and the mainboard 10 sends the state of the goods channel to the expansion nixie tube 50 through the expansion nixie tube interface 15; the expansion nixie tube 50 is used to receive the state of the goods channel; when the goods channel state is goods channel opened, the opened goods channel and the corresponding goods channel number are displayed.

[0073] In the embodiments of the present application, the extended nixie tube 50 can be connected to the purchase screen of the water vending machine or the customer's mobile phone. When the customer purchases an item, the customer can directly pay by scanning the code. Different channels have their own corresponding two-dimensional codes. After payment is completed, the device will open the corresponding channel electromagnetic valve, and the corresponding channel door will be opened, and the customer can directly open the door to take the goods. The payment amount will be transferred to the merchant account bound to the device.

[0074] Specifically, the extended nixie tube 50 can ensure that the channel state and the goods state information can be displayed clearly and accurately. The extended nixie tube 50 is an important part of the user interface, which helps users quickly understand the current state of the vending machine through an intuitive display method. The extended nixie tube 50 can display the opened channel and the corresponding channel number in real time according to the state of the channel. This display method enables users to understand which channels are in use at a glance, ensuring normal goods delivery.

[0075] In some embodiments of the present application, the extended nixie tube 50 is connected to the mainboard 10 through a 5P shielded wire. The extended nixie tube 50 is integrated with a TM1638 chip.

[0076] Specifically, the main function of the 5P shielded wire is to provide a stable and reliable signal transmission channel to ensure that the mainboard 10 can accurately send data to the extended nixie tube 50 for display. At the same time, the design of the shielding layer effectively reduces the influence of external electromagnetic interference on signal transmission, improving the overall stability of the system. The extended nixie tube 50 is integrated with a TM1638 chip, which is responsible for processing data from the mainboard 10.

[0077] The TM1638 chip, as the core component of the extended nixie tube, has powerful data processing and driving capabilities. It can receive digital signals from the mainboard 10 and convert these signals into images or text that can be displayed according to the preset display logic. At the same time, the TM1638 chip also supports multiple display modes, such as static display and dynamic scanning, providing users with a rich selection of display options.

[0078] In some embodiments of the present application, the electromagnetic lock 30 is provided with a 4p terminal block, which contains four pins with a spacing of 2.54mm. The 4p terminal block is a reverse insertion prevention structure. Two pins are used to connect with the electromagnetic lock control output end 12, and the other two pins are used to connect with the electromagnetic lock state receiving end 14. The design of the 4p terminal block not only provides a standardized connection interface, but also ensures compatibility and interchangeability with other components through standardization of pin spacing. At the same time, the design of the reverse insertion prevention structure effectively prevents connection errors, improving the safety and reliability of the system.

[0079] The state indicating lamp 40 is provided with a 2p terminal seat containing two pins, and the 2p terminal seat is a reverse insertion prevention structure and is used to be connected with the state indicating lamp control output end 13. The design of the 2p terminal seat simplifies the connection process of the state indicating lamp 40 and effectively prevents connection errors through the reverse insertion prevention structure. This design not only improves the safety and reliability of the system, but also makes the replacement and maintenance of the state indicating lamp 40 more convenient.

[0080] Specifically, the reverse insertion prevention structure can be a physical blocking structure inside the terminal seat, such as a flange, a groove or a notch, which can prevent the plug from being inserted in the wrong way. When the plug tries to be inserted in the wrong way, these blocking structures will prevent the plug from being inserted further, thereby playing a role in preventing reverse insertion.

[0081] Or in some terminal seats, a locking mechanism can also be designed to ensure the secure connection of the plug and prevent reverse insertion. This locking mechanism usually includes a movable lock or buckle that can be locked in place after the plug is correctly inserted, preventing the plug from loosening or reverse insertion. The specific structure of the reverse insertion prevention lock is not limited in the present application.

[0082] From the above, it can be seen that the water vending machine extension vending function device of the present application, when in use, the user selects the required goods through the user interface of the water vending machine, the mainboard can receive the user input of the water vending machine mainboard, process the data, send the control signal according to the user selection, and control the opening or closing of the corresponding electromagnetic lock. After the electromagnetic lock receives the signal, it performs the opening or closing action and feeds back the channel state information to the mainboard. When the mainboard detects that the inventory is insufficient, the mainboard sends the goods state information to the state indicating lamp, drives the state indicating lamp to display the corresponding state, and displays the corresponding channel state and goods information through the extended nixie tube, helping the user to quickly find the required goods. The mainboard is connected to other structures through a standardized connection interface, facilitating the maintenance and upgrading of the system. The water vending machine extension vending function device of the present application is connected with the water vending machine mainboard, which extends the vending function of the water vending machine, and at the same time can be connected with multiple water vending machines, facilitating the background management and further expanding the vending range of the water vending machine. The water vending machine extension vending function device can be used on any installed water vending machine, and the merchant only needs to prepare a vending cabinet without the need to find another place and increase the networking cost.
