Detailed implementation manners

[0050] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0051] As Figures 1 - 12 shown, an intelligent vending cabinet in an embodiment of the present invention includes a cabinet body 10, a cabinet door 20, an intelligent interaction panel 30, multiple rows of placement mechanisms 40, a moving mechanism 50, a reprocessing device 60, and a liquefied gas tank 70.

[0052] Among them, a cabinet door 20 is rotatably installed at the front end of the cabinet body 10, and a highly transparent glass is provided on the cabinet door 20 so that users can view the types of goods inside the cabinet body 10. In this embodiment, beverages are taken as an example.

[0053] An intelligent interaction panel 30 is fixedly installed on the cabinet door 20. The intelligent interaction panel 30 has a touch function, and users can obtain a QR code through touch and purchase beverages in the cabinet by scanning the code.

[0054] As Figure 9 and Figure 10 shown, the multi-row placement mechanism 40 includes shelves 41 fixedly installed inside the cabinet body 10 in multiple rows. Multiple groups of conveyor belts 42 are installed on each row of shelves 41. Beverages are placed on the conveyor belts 42, and automatic conveying and supply can be realized. Among them, partition plates 43 are provided on both sides of each group of conveyor belts 42. Multiple commodity channels can be separated through the partition plates 43 to classify and place various beverages.

[0055] A motor rotating shaft 44 is rotatably installed at the front end of the shelf 41. The motor rotating shaft 44 can rotate self-driven by a motor. Multiple groups of processing platforms 45 are fixedly installed on the motor rotating shaft 44. The multiple groups of processing platforms 45 correspond one-to-one with the multiple groups of conveyor belts 42. The processing platform 45 is located at the front end of the conveyor belt 42, so that the beverages on the conveyor belt 42 can be conveyed to the processing platform 45.

[0056] Among them, as Figure 11 shown, a guiding block 452 is fixedly installed at one end of the processing platform 45 close to the conveyor belt 42. The upper end surface of the guiding block 452 is a smooth inclined surface, so that the beverage can slide onto the processing platform 45 through the guiding block 452. The end surface of the guiding block 452 close to the conveyor belt 42 is arc-shaped, so that the guiding block 452 can infinitely approach one end of the conveyor belt 42, so that the beverages on the conveyor belt 42 can be smoothly transmitted to the processing platform 45.

[0057] Specifically, in the initial state, all the processing platforms 45 are vertically downward. After the user selects a beverage and pays, the rows of processing platforms 45 corresponding to the beverage are all flipped to the horizontal state under the drive of the motor rotating shaft 44, and the rest remain in the vertical state to avoid blocking subsequent reprocessing. Then the corresponding conveyor belt 42 starts, and the specified beverage is transmitted to the processing platform 45 at its front end, waiting for reprocessing and picking up.

[0058] In addition, a groove 451 is provided on the upper end surface of the processing platform 45. One end of the groove 451 close to the conveyor belt 42 is open. The beverage enters the inside of the groove 451 from the open end, and the beverage can be prevented from slipping inside the groove 451 to ensure that the beverage is safely and smoothly transmitted to the processing platform 45.

[0059] As Figures 1 - 3As shown, the moving mechanism 50 includes a Y-axis moving base 51 and an X-axis moving base 53. The Y-axis moving base 51 is fixedly installed on one side inside the cabinet body 10. A Y-axis moving block 52 is slidably installed on the Y-axis moving base 51, and the Y-axis moving block 52 can slide up and down on the Y-axis moving base 51. The X-axis moving base 53 is fixedly installed on the Y-axis moving block 52, and an X-axis moving block 54 is fixedly installed on the X-axis moving base 53. The X-axis moving block 54 can slide horizontally on the X-axis moving base 53.

[0060] Among them, the ways to drive the Y-axis moving block 52 to slide up and down and drive the X-axis moving block 54 to slide horizontally can be: respectively install vertical and horizontal ball screws driven by motors inside the Y-axis moving base 51 and the X-axis moving base 53, and install rollers driven by motors on the Y-axis moving block 52 and the X-axis moving block 54, and move automatically through the rollers, etc.

[0061] As Figure 1 、 Figure 4 and Figure 5 shown, the reprocessing device 60 includes a processing chamber 61. The processing chamber 61 is fixedly installed at the bottom end of the X-axis moving block 54. Through the horizontal sliding of the X-axis moving block 54 on the X-axis moving base 53 and the sliding up and down of the Y-axis moving block 52 on the Y-axis moving base 51, the processing chamber 61 can be flexibly moved inside the cabinet body 10 to any group of X-axis moving blocks 54 to reprocess the drinks on the X-axis moving blocks 54.

[0062] Among them, the lower end surface of the processing chamber 61 matches the upper end surface shape of the processing platform 45. When the processing chamber 61 moves to the processing platform 45, its lower end surface can be closely attached to the upper end surface of the processing platform 45, so that the processing chamber 61 and the processing platform 45 can form a closed space. Reprocessing in the closed space can not only avoid affecting other drinks in the cabinet, but also be conducive to quickly and efficiently realizing the reprocessing of drinks.

[0063] A microwave generating module 62 is fixedly installed at the front end of the processing chamber 61. The microwave generating module 62 internally includes at least components such as a magnetron, a capacitor, a transformer, and a fan, and can generate microwaves to microwave heat the drinks.

[0064] Specifically, after the selected drink is transported to the designated processing platform 45, if the drink needs to be heated, the packaging needs to be manually removed to ensure that the heat can be effectively dissipated during the heating process, and then the reprocessing program is started to make the processing chamber 61 move to the corresponding X-axis moving block 54, and the drink is microwave heated through the microwave generating module 62. The specific heating temperature can be flexibly adjusted by the heating time or the microwave power to meet the needs of different people.

[0065] As Figure 4 、 Figure 5And Figure 8 As shown in Figure 8 , the air flow circulation mechanism includes a circulation air pipe 66. One end of the circulation air pipe 66 is fixedly installed with an air extraction hood 661. One end of the air extraction hood 661 penetrates into the interior of the processing chamber 61, and the air inside the processing chamber 61 can be extracted through the air extraction hood 661.

[0066] The other end of the circulation air pipe 66 is fixedly installed with an air inlet box 65. The air inlet box 65 is communicated with the interior of the processing chamber 61 so as to be able to re-inject the extracted air into the interior of the processing chamber 61 to achieve the function of air flow circulation.

[0067] Specifically, a fixed plate 651 is fixedly installed inside the air inlet box 65. A fan 652 is installed on one side of the fixed plate 651. By starting the fan 652, the air flow inside the processing chamber 61 can be driven to circulate. An air filter element 6511 is fixedly installed on the fixed plate 651. Through the air filter element 6511, the air can be filtered during the air flow circulation process to remove the substances volatilized during the heating of the drink, so as to avoid affecting the environment inside the cabinet. Through the air flow circulation during the microwave heating process, the drink can be heated more evenly, and the volatile substances generated during the heating process can be removed, ensuring that the heating of the drink will not pollute the environment inside the cabinet.

[0068] Preferably, in this embodiment, the air filter element 6511 is preferably an activated carbon filter element, which can not only remove volatile substances but also adsorb and remove odors, enhancing environmental protection.

[0069] As Figure 11 shown in Figure 11 , an assembly hole 11 is provided at a position near the top inside the cabinet 10. A liquefied gas tank 70 is placed inside the assembly hole 11. The liquefied gas tank 70 is filled with low-temperature liquid nitrogen, and the drink can be quickly cooled through the low-temperature liquid nitrogen.

[0070] A cold air pipe 67 is connected between the liquefied gas tank 70 and the circulation air pipe 66. The low-temperature liquid nitrogen inside the liquefied gas tank 70 can enter the cold air pipe 67 through the cold air pipe 67 to generate low-temperature air, and the drink can be quickly cooled by using the low-temperature air.

[0071] Wherein, a second electromagnetic valve 71 is fixedly installed on the cold air pipe 67, and the second electromagnetic valve 71 is used to control the on-off of the cold air pipe 67.

[0072] Specifically, after the selected drink is transported to the designated processing stage 45, if the drink needs to be cooled, the reprocessing procedure can be directly started. The processing chamber 61 is moved to the corresponding X-axis moving block 54, the second solenoid valve 71 is opened, and the blower 652 is started. During the process of air circulation inside the processing chamber 61, low-temperature liquid nitrogen is injected to form low-temperature air, and the drink is rapidly cooled by the low-temperature air. The specific cooling temperature can be adjusted by the cooling time to meet the needs of different people.

[0073] It should be noted that an automatic pressure relief valve should also be installed on the processing chamber 61 or the circulating air pipe 66 to ensure safety during the reprocessing.

[0074] Through the above reprocessing methods of heating and cooling, users can purchase drinks that meet their own needs. In the cold winter, hot drinks can be purchased through this intelligent vending machine. In the hot summer, cold drinks that meet the needs of users can be purchased through this intelligent vending machine, thus meeting the needs of different seasons and different people for drinks at different temperatures.

[0075] More importantly, since it can independently achieve rapid reprocessing of specific drinks, this intelligent vending machine does not need to continuously regulate and maintain a constant internal temperature, greatly reducing the input and operating costs, saving electric energy, and having a compact structure and a small footprint, with broad application prospects.

[0076] In addition, this intelligent vending machine not only has outstanding advantages in drinks. It is understood that currently, it takes at least fifteen minutes to heat self-heating rice using the self-heating package inside, with extremely low efficiency. This intelligent vending machine can also be applied to the intelligent retail of self-heating rice, and the use of microwave heating greatly shortens the waiting time of users, which is conducive to the promotion and sales of self-heating rice. However, it should be noted that when heating self-heating rice, not only the packaging needs to be opened, but also the self-heating package needs to be taken out to eliminate potential safety hazards to ensure safe use.

[0077] As Figure 11 shown, the inside of the processing stage 45 is a hollow structure. A water injection port 453 is fixedly installed on the processing stage 45, and an automatic pressure relief valve is also installed on the water injection port 453. Water is injected into the hollow structure through the water injection port 453. The purpose of injecting water into the processing stage 45 is that when microwave heating is carried out, the water inside the processing stage 45 can be rapidly heated, causing the temperature of the processing stage 45 itself to rise rapidly, so as to quickly form a base with a relatively high temperature, conducting heat from the bottom upwards to assist heating and improve the heating efficiency.

[0078] In addition, if a user purchases multiple drinks and needs to heat them multiple times, the base with a relatively high temperature can effectively shorten the time for multiple heating, reduce the waiting time of users, and give users a good usage experience.

[0079] As Figures 4 - 7 shown, an internal rack 63 and an internal box 64 are fixedly installed on the inner wall of the processing bin 61. Both the internal rack 63 and the internal box 64 are installed close to the inner wall of the processing bin 61, and the internal rack 63 and the internal box 64 form a closed square frame.

[0080] Among them, the air inlet box 65 is connected to the inside of the internal rack 63. Multiple groups of air blowing holes 631 are respectively opened on two opposite side surfaces of the internal rack 63, and a horizontal air blowing port 632 is opened on one side surface of the internal rack 63. The circulating air will enter the inside of the internal rack 63 first before entering the inside of the processing bin 61, and then be ejected through the multiple groups of air blowing holes 631 and the horizontal air blowing port 632.

[0081] The openings of the multiple groups of air blowing holes 631 all incline upward, and the inclination angles of adjacent air blowing holes 631 are different, so that the circulating air flow can blow to different parts of the drink, so as to uniformly heat or cool it.

[0082] A horizontal air extraction port 641 matching the horizontal air blowing port 632 is opened on one side surface of the internal box 64, and a connecting pipe 642 is fixedly installed on the internal box 64. One end of the connecting pipe 642 is connected to the inside of the air extraction hood 661. While the air extraction hood 661 extracts air outward, the air inside the internal box 64 can be extracted through the connecting pipe 642, that is, the horizontal air extraction port 641 on the internal box 64 can extract air.

[0083] Among them, the horizontal plane where the horizontal air blowing port 632 and the horizontal air extraction port 641 are located is lower than the horizontal plane where the air blowing holes 631 are located. The gas blown out by the horizontal air blowing port 632 can just be extracted by the horizontal air extraction port 641, so as to form an invisible air curtain below the air blowing holes 631. With the help of this air curtain, the opening of the processing bin 61 can be closed, and the air inside the processing bin 61 is difficult to diffuse outward.

[0084] Specifically, whether in the reprocessing process of heating or cooling, keeping the air flow inside the processing bin 61 circulating can effectively improve the reprocessing efficiency and effect. After the reprocessing is completed, if it is necessary to continuously reprocess multiple drinks, at this time, after the processing bin 61 is moved away and the reprocessed drink is taken out, keeping the hot air or cold air inside the processing bin 61 from losing can effectively shorten the time of multiple processing. Therefore, if multiple reprocessings are required, after the processing bin 61 is moved away, there is no need to turn off the fan 652, that is, keep the air inside the processing bin 61 circulating, and use the air curtain formed by the horizontal air blowing port 632 and the horizontal air extraction port 641 to prevent the air inside the processing bin 61 from overflowing. When reprocessing again, the processing time can be effectively shortened, so as to continuously and efficiently reprocess the drink, and the recycling of energy is realized, saving energy.

[0085] As Figure 4As shown, an interface for connecting the cold gas pipe 67 and a first solenoid valve 662 are successively arranged on the circulating gas pipe 66. The interface is close to the air inlet box 65, and the first solenoid valve 662 is close to the air extraction hood 661. By closing the first solenoid valve 662, the air extraction pipeline of the processing chamber 61 can be cut off, but low-temperature liquid nitrogen can still be injected into the processing chamber 61 through the cold gas pipe 67. At this time, the low-temperature liquid nitrogen can only be ejected through the opening below the processing chamber 61, and the processing chamber 61 has the function of fire fighting by ejecting the low-temperature liquid nitrogen.

[0086] Specifically, if the user operates by mistake and accidentally causes a fire in the cabinet, the first solenoid valve 662 can be closed at this time, and at the same time, the second solenoid valve 71 and the fan 652 are opened, and low-temperature liquid nitrogen is continuously injected into the processing chamber 61. The low-temperature liquid nitrogen quickly vaporizes to form low-temperature nitrogen gas and is ejected from below the processing chamber 61, enabling the processing chamber 61 to carry out fire fighting on the cabinet, greatly improving the safety performance during the operation of the intelligent vending machine.

[0087] An intelligent vending system includes a login module, a payment module, a pickup module, and a reprocessing module;

[0088] The login module includes an intelligent interaction panel 30. The user scans the QR code through the intelligent interaction panel 30 to log in and select the product and the reprocessing information of the product;

[0089] The payment module is used to determine the payment amount and payment method according to the selected product information and the selected payment method information, generate a payment instruction, and send the product information after payment to the pickup module;

[0090] The pickup module includes a conveyor belt 42 and a processing platform 45. According to the product information after payment, the corresponding conveyor belt 42 is started to convey the product to the processing platform 45 as the product to be picked up;

[0091] The reprocessing module includes a moving mechanism 50 and a reprocessing device 60. The moving mechanism 50 is used to drive the reprocessing device 60 to move, so that the reprocessing device 60 heats or cools the product to be picked up according to the reprocessing information.

[0092] In use, the user scans a QR code through the intelligent interaction panel 30, selects a specified beverage, and selects the corresponding reprocessing type according to their own needs. After payment is completed, the beverage on the specified conveyor belt 42 is transported to the front processing stage 45. If heating is required, the package needs to be opened first to ensure that heat can be effectively dissipated during the heating process, and then the reprocessing program is started to move the processing chamber 61 to the corresponding X-axis moving block 54, and the beverage is heated by the microwave generation module 62; if cooling is required, the reprocessing program can be directly started to move the processing chamber 61 to the corresponding X-axis moving block 54, open the second solenoid valve 71 and start the fan 652. During the process of air circulation inside the processing chamber 61, low-temperature liquid nitrogen is injected to form low-temperature air, and the beverage is rapidly cooled by the low-temperature air.

[0093] During the reprocessing of heating or cooling, keep the air flow circulating inside the processing chamber 61 to improve the reprocessing efficiency and effect. If multiple reprocessing is required, after removing the processing chamber 61, there is no need to turn off the fan 652, that is, keep the air circulation inside the processing chamber 61, and use the air curtain formed by the horizontal air blowing port 632 and the horizontal air extraction port 641 to prevent the air inside the processing chamber 61 from overflowing. When reprocessing again, the processing time can be effectively shortened, so as to continuously and efficiently reprocess the beverage.

[0094] Through the reprocessing device 60 that can move flexibly, the present invention can quickly perform specified reprocessing on the specified commodities purchased by users according to the needs of each user to meet the needs of different seasons and different people, so that the intelligent vending machine no longer needs to continuously adjust the temperature inside the cabinet, greatly reducing the investment and operating costs of the intelligent vending machine and saving energy;
