When the two-dimensional code used for water dispensing of the water vending machine is damaged, the merchant cannot get feedback in the first time, resulting in poor user experience.

[0045] To solve the above problems, the present application provides a water vending machine control device, which refers to Figure 1 and Figure 2As shown, the vending machine control device comprises a vending machine mainboard 10, a touch screen 20 and a connection line 30; the vending machine mainboard 10 is electrically connected with the touch screen 20 through the connection line 30; the touch screen 20 is used to display vending machine information data, interact with the user, obtain an instruction signal and transmit the instruction signal to the vending machine mainboard 10; the output end of the vending machine mainboard 10 is connected with a vending machine component, and the vending machine component is used to receive the instruction signal to control the vending machine component to execute the instruction according to the instruction signal.

[0056] The relay can accurately control the power supply of the external power supply to the water vending machine components by receiving instructions from the water vending machine mainboard 10. This not only helps to reduce energy consumption, but also quickly cuts off the power supply when a fault occurs to protect the water vending machine components from damage.

[0057] By introducing the relay and the power control interface, the water vending machine control device realizes accurate control of the power supply to the water vending machine components. This helps to reduce energy consumption, and by accurately controlling the power supply to the water vending machine components, the water vending machine control device can reduce faults and damage caused by power problems. This helps to reduce the maintenance cost and time of the water vending machine.

[0058] In some embodiments of the present application, refer to Figure 4As shown, the vending water machine mainboard 10 further includes a power input interface, a power indicator light 11 and a voltage stabilizing circuit; the power input interface is connected to the input end of the voltage stabilizing circuit, and the output end of the voltage stabilizing circuit is connected to the power indicator light 11; the power input interface is used for connecting the vending water machine mainboard 10 to a 12V power supply; the voltage stabilizing circuit is used for stabilizing the input 12V voltage, and the power indicator light is used for displaying whether the 12V power supply is powered.

[0059] The voltage stabilizing circuit can eliminate the influence of external voltage fluctuation on the internal circuit of the vending water machine mainboard 10, ensure that each circuit module can work in a stable voltage environment, and thus improve the reliability and stability of the vending water machine. The introduction of the power indicator light 11 provides an intuitive power state monitoring means for the operation and maintenance personnel. By observing the on-off state of the indicator light, the operation and maintenance personnel can quickly judge whether the vending water machine mainboard 10 has obtained stable power supply, so as to discover problems in time and handle them.

[0060] The design of introducing the power input interface, the power indicator light 11 and the voltage stabilizing circuit and other components in the embodiment of the application not only improves the power stability and reliability of the vending water machine mainboard 10, but also facilitates the operation and maintenance personnel to monitor the power state, reduces the maintenance cost, and improves the user experience.

[0061] In some embodiments of the application, with reference to Figure 5 and Figure 6 As shown, the relay includes a first relay and a second relay; the external power supply includes a 24V power supply and a 220V power supply; the vending water machine components include a water inlet valve, a flushing valve, a water making pump, a water taking lamp, a filling system, an advertising lamp, an ozone system, ultraviolet light, and a temperature control system; the first relay is electrically connected to the 24V power supply and the water inlet valve, the flushing valve, and the water making pump; the second relay is electrically connected to the 220V power supply and the water taking lamp, the filling system, the advertising lamp, the ozone system, the ultraviolet light, and the temperature control system.

[0062] Specifically, the first relay is specially used for controlling the connection between the 24V power supply and the low-voltage components in the vending water machine. Specifically, the contact of the first relay is connected to the output end of the 24V power supply and the power input end of the low-voltage components such as the water inlet valve, the flushing valve, and the water making pump. When the first relay receives a closing instruction from the vending water machine mainboard, its contact is closed, so that the 24V power supply can provide stable power support for these low-voltage components. The 24V power supply has the characteristics of safety and stability, and can provide sufficient power for the water inlet valve, the flushing valve, the water making pump and other components, while ensuring the safety of operation.

[0063] The second relay is used to control the connection between the 220V power supply and the high-voltage components in the water vending machine. Its contacts are connected to the output end of the 220V power supply and the power input end of high-voltage components such as the water taking lamp, the filling system, the advertising lamp, the ozone system, the ultraviolet light, and the temperature control system. When the second relay receives a closing instruction from the main board of the water vending machine, its contacts are also closed, allowing the 220V power supply to provide the required power for these high-voltage components. The 220V power supply has the characteristics of high power and high efficiency, and can provide sufficient power support for high-power components such as the water taking lamp, the filling system, and the advertising lamp.

[0064] The present embodiment classifies and precisely controls the connection between the external power supply and the components of the water vending machine by introducing the first relay and the second relay. The power management system of the water vending machine can precisely control the power supply of each component. This not only helps to reduce energy consumption, but also quickly cuts off the power supply when a fault occurs, protecting the components of the water vending machine from damage. Precise power management also helps to reduce faults and abnormal situations that occur during the operation of the water vending machine.

[0065] In some embodiments of the present application, with reference to Figure 7 As shown in the figure, the main board 10 of the water vending machine includes a first card interface and a second card interface. The components of the water vending machine also include a first outlet and a second outlet of the water vending machine. The first card interface is electrically connected to the first card and is used to receive the first payment signal of the first card to control the water outlet of the first outlet of the water vending machine. The second card interface is electrically connected to the second card and is used to receive the second payment signal of the second card to control the water outlet of the second outlet of the water vending machine.

[0066] The first card and the second card are used to receive payment information (such as IC card, RFID card, etc.) of users. When a user inserts or approaches the first card and the second card, a payment operation can be completed and a first payment signal and a second payment signal can be generated and transmitted to the main board 10 of the water vending machine to control the water outlet of the first outlet and the second outlet of the water vending machine.

[0067] In the present embodiment, the water vending machine can independently control two water outlets. This allows the water vending machine to meet the needs of different users at the same time, improving the flexibility and convenience of the water vending machine. Independent control of the water outlet allows users to choose different water outlets for water taking according to their own needs without waiting for other users to complete the water taking operation. This not only improves the efficiency of water taking for users, but also improves the overall experience of users.

[0068] In some embodiments of the present application, a coin slot is provided on the water vending machine. With reference to Figure 8As shown, the vending machine mainboard 10 is in communication connection with the coin acceptor, and the coin acceptor is used for the user to put in coins and generate a third payment signal to send to the vending machine mainboard 10; the vending machine mainboard 10 is used for receiving the third payment signal and controlling the vending machine first outlet or the vending machine second outlet to discharge water.

[0069] The main function of the coin acceptor is to provide a simple and direct payment method. The user only needs to put the coins into the coin acceptor, and the coin acceptor can automatically identify and process the coins, and then generate a third payment signal to send to the vending machine mainboard 10. This payment method does not need to rely on electronic devices (such as mobile phones, IC cards, etc.), so it is more convenient and popular. By introducing the coin acceptor as a new payment method, the vending machine can support more types of payment methods. This not only meets the payment needs of different users, but also improves the use rate and market share of the vending machine, reduces the payment threshold of the user, and improves the payment experience and convenience of the user.

[0070] In some embodiments of the present application, the connection line 30 is a 4-core shielded wire, and the interface of the vending machine mainboard 10 connected to the connection line 30 is a 2.0 pitch anti-reverse terminal seat.

[0071] 4-core shielded wire design means that it contains 4 internal wires, each wrapped in a shielding layer. The shielding layer prevents external electromagnetic interference from affecting signal transmission, ensuring the accuracy and stability of signal transmission. The interface of the vending machine mainboard 10 is designed as a 2.0 pitch anti-reverse terminal seat. 2.0 pitch refers to the distance between adjacent two terminals, and this design not only ensures the electrical isolation between terminals, but also facilitates the insertion and fixation of the connection line. The design of the anti-reverse terminal seat is to prevent the connection line from being inserted in reverse, that is, the positive and negative poles or signal lines are reversed. Once reversed, it may cause the vending machine mainboard 10 to be damaged or unable to work normally. Therefore, the design of the anti-reverse terminal seat is an important measure to ensure the safe and reliable operation of the vending machine mainboard 10.

[0072] By using 4-core shielded wire as the connection line and 2.0 pitch anti-reverse terminal seat as the interface of the vending machine mainboard 10, the present scheme effectively improves the stability and accuracy of signal transmission. This ensures that the vending machine mainboard 10 can accurately and reliably receive and process signals from the touch screen 20, thereby ensuring the normal operation of the vending machine.

[0073] In some embodiments of the present application, referring to Figure 9 As shown, the input end of the vending machine mainboard 10 is also connected with an optical coupler, and the optical coupler is used for optically coupling the instruction signal to isolate abnormal signals. In this embodiment, the optical coupler is connected to the input end of the vending machine mainboard 10, and its main purpose is to optically couple the instruction signal from the external device.

[0074] The principle of optical coupling isolation is that when the command signal of the external device passes through the light-emitting diode, it will excite the light-emitting diode to emit light, and the generated light signal is received by the photosensitive semiconductor and converted into an electric signal, which is then transmitted to the water vending machine mainboard 10. Since the transmission of the light signal does not require direct electrical connection, the optical coupler can effectively isolate the electrical connection between the external device and the water vending machine mainboard 10, thereby preventing abnormal signals (such as high voltage, strong current, electromagnetic interference, etc.) from damaging the water vending machine mainboard 10.

[0075] The introduction of the optical coupler achieves electrical isolation between the external device and the water vending machine mainboard 10, effectively preventing damage to the water vending machine mainboard 10 by abnormal signals. This not only improves the safety of the water vending machine, but also ensures its stable operation in complex electromagnetic environments. Optical coupling isolation can isolate external electromagnetic interference and ensure accurate transmission of command signals. This is of great significance for improving the anti-interference ability of the water vending machine, reducing the rate of misoperation and failure.

[0076] From the above embodiment, it can be seen that the present application provides a water vending machine control device, which comprises a water vending machine mainboard, a touch screen and a connection line. The water vending machine mainboard is electrically connected to the touch screen through the connection line. The touch screen is used to display water vending machine information data for interaction with users. Through the touch screen, users can easily view and operate the water vending machine information, such as selecting the amount of water to purchase and the payment method, etc. The operation is simple and intuitive. At the same time, the present application supports multiple payment methods such as card swiping and coin feeding, meeting the payment needs of different users and improving the ease of use and convenience of the water vending machine. The water vending machine mainboard has networking function and can be connected to the background system for communication, realizing remote monitoring and management. This enables administrators to view the running status and fault alarm information of the water vending machine in real time and timely handle and maintain, thereby ensuring the stable operation and efficient service of the water vending machine. The water vending machine control device scheme provided in the present embodiment has significant beneficial effects in improving user experience, improving management efficiency, saving energy and protecting the environment, and being easy to maintain and expand, etc., and has high practical value and market application prospect.

[0077] Other embodiments of the present disclosure will be readily apparent to those skilled in the art upon considering the disclosure and examples herein. The present application is intended to cover any variations, uses, or adaptive changes to the present disclosure that adhere to the general principles of the present disclosure and include common knowledge or conventional techniques in the technical field of the present disclosure not disclosed by the present disclosure.
