[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 drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0051] like Figure 1-Figure 12 As shown, a smart vending machine in one embodiment of the present invention includes a cabinet body 10, a cabinet door 20, a smart interactive panel 30, a multi-row placement mechanism 40, a moving mechanism 50, a reprocessing device 60 and a liquefied gas tank 70.

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

[0053] A smart interactive panel 30 is fixedly mounted on the cabinet door 20. The smart interactive panel 30 has a touch function. The user can obtain a QR code by touching it and purchase drinks in the cabinet by scanning the code.

[0054] like Fig. 9 and Fig.10 As shown, the multi-row placement mechanism 40 includes multiple rows of shelves 41 fixedly installed inside the cabinet 10, and multiple groups of conveyor belts 42 are installed on each row of shelves 41. Drinks are placed on the conveyor belts 42 to achieve automatic conveying and supply. Partition plates 43 are provided on both sides of each group of conveyor belts 42, and multiple commodity channels can be separated by the partition plates 43 to place multiple drinks in a classified manner.

[0055] A motor shaft 44 is rotatably mounted at the front end of the shelf 41, and the motor shaft 44 can rotate under the drive of the motor. Multiple sets of processing platforms 45 are fixedly mounted on the motor shaft 44. The multiple sets of processing platforms 45 correspond to the multiple sets of conveyor belts 42 one by one. The processing platforms 45 are located at the front end of the conveyor belt 42, so that the beverages on the conveyor belt 42 can be transported to the processing platforms 45.

[0056] Among them, Fig.11 As shown, a guide block 452 is fixedly mounted on one end of the processing platform 45 close to the conveyor belt 42, and the upper end surface of the guide block 452 is a smooth inclined surface, so that the beverage can slide onto the processing platform 45 through the guide block 452. The end surface of the guide block 452 close to the conveyor belt 42 is arc-shaped, so that the guide block 452 can be infinitely close to one end of the conveyor belt 42, so that the beverage on the conveyor belt 42 can be smoothly transferred to the processing platform 45.

[0057] Specifically, in the initial state, all processing platforms 45 are vertically facing downward. After the user selects a drink and pays, the row of processing platforms 45 corresponding to the drink are flipped to a horizontal state under the drive of the motor shaft 44, and the rest remain in a vertical state to avoid obstruction to subsequent reprocessing. Then the corresponding conveyor belt 42 is started to transfer the specified drink to the processing platform 45 in front of it, waiting for reprocessing and pickup.

[0058] In addition, a groove 451 is provided on the upper end surface of the processing platform 45. The groove 451 is open at one end close to the conveyor belt 42. The beverage enters the interior of the groove 451 from the open end, and the beverage is prevented from slipping inside the groove 451, thereby ensuring that the beverage is safely and smoothly transferred to the processing platform 45.

[0059] like Figure 1-Figure 3As shown, the moving mechanism 50 includes a Y-axis moving seat 51 and an X-axis moving seat 53. The Y-axis moving seat 51 is fixedly installed on one side inside the cabinet 10. A Y-axis moving block 52 is slidably installed on the Y-axis moving seat 51, and the Y-axis moving block 52 can slide and rise and fall on the Y-axis moving seat 51; the X-axis moving seat 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 seat 53, and the X-axis moving block 54 can slide horizontally on the X-axis moving seat 53.

[0060] Among them, the method of driving the Y-axis moving block 52 to slide and rise and fall and driving the X-axis moving block 54 to slide horizontally can be: installing vertical and horizontal ball screws driven by motors inside the Y-axis moving seat 51 and the X-axis moving seat 53 respectively, installing rollers driven by motors on the Y-axis moving block 52 and the X-axis moving block 54, and automatically moving by the rollers.

[0061] like Figure 1 , Figure 4 and Figure 5 As shown, the reprocessing device 60 includes a processing bin 61, which is fixedly mounted 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 seat 53 and the sliding and lifting of the Y-axis moving block 52 on the Y-axis moving seat 51, the processing bin 61 can be flexibly moved inside the cabinet 10 to any group of X-axis moving blocks 54, so as to be able to reprocess the beverage on the X-axis moving block 54.

[0062] The lower end surface of the processing chamber 61 matches the shape of the upper end surface of the processing platform 45. When the processing chamber 61 is moved onto the processing platform 45, its lower end surface can be closely fitted with 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 a closed space can avoid affecting other drinks in the cabinet and is conducive to the rapid and efficient 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 includes at least a magnetron, a capacitor, a transformer, a fan and other components, and can generate microwaves to heat the beverage.

[0064] Specifically, after the selected beverage is transferred to the designated processing carrier 45, if the beverage 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 procedure is started to move the processing chamber 61 to the corresponding X-axis moving block 54, and the beverage is heated by microwaves through the microwave generating module 62. The specific heating temperature can be flexibly adjusted by the heating time or microwave power to meet the needs of different people.

[0065] like Figure 4 , Figure 5and Figure 8 As shown, the air circulation mechanism includes a circulating air pipe 66 , one end of which is fixedly mounted with an exhaust hood 661 , one end of which penetrates into the interior of the processing chamber 61 , and the air inside the processing chamber 61 can be extracted through the exhaust hood 661 .

[0066] An air inlet box 65 is fixedly installed at the other end of the circulating air pipe 66. The air inlet box 65 is connected to the interior of the processing chamber 61 so that the extracted air can be re-injected into the interior of the processing chamber 61 to achieve the effect of air circulation.

[0067] Specifically, a fixing plate 651 is fixedly installed inside the air inlet box 65, and a fan 652 is installed on one side of the fixing plate 651. By starting the fan 652, the air circulation inside the processing chamber 61 can be driven. An air filter element 6511 is fixedly installed on the fixing plate 651. The air filter element 6511 can filter the air during the air circulation process to remove the substances volatilized during the heating process of the beverage to avoid affecting the environment inside the cabinet. Through the air circulation during the microwave heating process, the beverage can be heated more evenly, and the volatile substances generated during the heating process can be removed, ensuring that the heating of the beverage 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 absorb and remove odors, thereby enhancing environmental protection.

[0069] like Fig.11 As shown, an assembly hole 11 is provided near the top of the cabinet 10 , and a liquefied gas tank 70 is placed inside the assembly hole 11 . The liquefied gas tank 70 is filled with low-temperature liquid nitrogen, which can achieve rapid cooling of beverages.

[0070] A cold air pipe 67 is connected between the liquefied gas tank 70 and the circulating 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 low-temperature air can be used to quickly cool the beverage.

[0071] A second solenoid valve 71 is fixedly installed on the cold air pipe 67 , and the second solenoid valve 71 is used to control the on and off of the cold air pipe 67 .

[0072] Specifically, after the selected beverage is transferred to the designated processing platform 45, if the beverage needs to be cooled, the reprocessing procedure 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 circulation of air inside the processing chamber 61, low-temperature liquid nitrogen is injected to form low-temperature air, and the beverage is quickly 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 is worth noting 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 process.

[0074] Through the above-mentioned heating and cooling reprocessing method, users can buy drinks that meet their needs. In the cold winter, they can buy hot drinks through the smart vending machine. In the hot summer, they can buy cold drinks that meet user needs through the smart vending machine, thereby meeting the needs of different seasons and different groups of people for drinks of different temperatures.

[0075] What is more noteworthy is that, because it can independently realize the rapid reprocessing of specific beverages, the smart vending machine does not need to continuously adjust to maintain a constant internal temperature, which greatly reduces investment and operating costs, saves electricity, and has a compact structure and small footprint, and has broad application prospects.

[0076] In addition, the smart vending machine not only has outstanding advantages in beverages. It is understood that it currently takes at least fifteen minutes to heat self-heating rice using the self-heating bag inside, which is extremely inefficient. The smart vending machine can also be used for smart retail of self-heating rice, and the use of microwave heating greatly shortens the user's waiting time, which is conducive to the promotion and sales of self-heating rice. However, it should be noted that when heating self-heating rice, it is necessary not only to open the package, but also to take out the self-heating bag to eliminate safety hazards and ensure safe use.

[0077] like Fig.11 As shown, the interior of the processing platform 45 is a hollow structure, and a water injection port 453 is fixedly installed on the processing platform 45. The water injection port 453 is also installed with an automatic pressure relief valve, and water is injected into the hollow structure through the water injection port 453. The purpose of injecting water into the processing platform 45 is that when microwave heating is performed, the water inside the processing platform 45 can be quickly heated, so that the temperature of the processing platform 45 itself is quickly increased, so as to quickly form a base with a higher temperature, and conduct heat from the bottom to the top to assist heating and improve heating efficiency.

[0078] In addition, if the user purchases multiple drinks that need to be heated multiple times, the higher temperature base can effectively shorten the time of multiple heating, reduce the user's waiting time, and give the user a good user experience.

[0079] like Figure 4-Figure 7 As shown, an internal frame 63 and an internal box 64 are fixedly mounted on the inner wall of the processing chamber 61. The internal frame 63 and the internal box 64 are both installed close to the inner wall of the processing chamber 61. The internal frame 63 and the internal box 64 form a closed square frame.

[0080] The air inlet box 65 is connected to the interior of the built-in frame 63. Two opposite sides of the built-in frame 63 are provided with a plurality of air blowing holes 631, and one side of the built-in frame 63 is provided with a horizontal air blowing port 632. The circulating air first enters the interior of the built-in frame 63 before entering the interior of the processing chamber 61, and then is ejected through the plurality of air blowing holes 631 and the horizontal air blowing port 632.

[0081] The openings of the multiple groups of blowing holes 631 are all inclined upward, and the inclination angles of adjacent blowing holes 631 are different, so that the circulating airflow can blow to different parts of the beverage to evenly heat or cool it.

[0082] A horizontal air extraction port 641 matching the horizontal air blowing port 632 is provided on one side of the built-in box 64. A connecting pipe 642 is fixedly mounted on the built-in box 64. One end of the connecting pipe 642 is connected to the inside of the air extraction hood 661. When the air extraction hood 661 is exhausting air outwards, the air inside the built-in box 64 can be extracted through the connecting pipe 642, that is, the horizontal air extraction port 641 on the built-in box 64 can be exhausted.

[0083] Among them, the horizontal plane where the horizontal blowing port 632 and the horizontal exhaust port 641 are located is lower than the horizontal plane where the blowing hole 631 is located. The gas blown out by the horizontal blowing port 632 can be extracted by the horizontal exhaust port 641, thereby forming an invisible air curtain under the blowing hole 631. With the help of this air curtain, the opening of the processing chamber 61 can be closed, making it difficult for the air inside the processing chamber 61 to diffuse outward.

[0084] Specifically, whether in the reprocessing process of heating or cooling, maintaining the circulation of the airflow inside the processing chamber 61 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 chamber 61 is removed and the reprocessed drinks are taken out, the heat or cold air inside the processing chamber 61 is kept from being lost, which can effectively shorten the time of multiple processing. Therefore, if multiple reprocessing is required, after the processing chamber 61 is removed, there is no need to turn off the fan 652, that is, the air inside the processing chamber 61 is kept circulating, and the air curtain formed by the horizontal blowing port 632 and the horizontal exhaust port 641 is used to prevent the air inside the processing chamber 61 from overflowing. When reprocessing again, the processing time can be effectively shortened, so that the drinks can be reprocessed continuously and efficiently, and the energy recycling is realized, saving energy.

[0085] like Figure 4As shown, the circulating air pipe 66 is provided with an interface for connecting the cold air pipe 67 and a first solenoid valve 662 in sequence, the interface is close to the air inlet box 65, and the first solenoid valve 662 is close to the exhaust hood 661. The exhaust pipeline of the processing chamber 61 can be cut off by closing the first solenoid valve 662, but low-temperature liquid nitrogen can still be injected into the processing chamber 61 through the cold air pipe 67. At this time, the low-temperature liquid nitrogen can only be sprayed out through the opening below the processing chamber 61. By spraying the low-temperature liquid nitrogen, the processing chamber 61 has the function of fire extinguishing.

[0086] Specifically, if a user makes an operational error and accidentally causes a fire in the cabinet, the first solenoid valve 662 can be closed and the second solenoid valve 71 and the fan 652 can be opened at the same time to continuously inject low-temperature liquid nitrogen into the processing chamber 61. The low-temperature liquid nitrogen quickly vaporizes to form low-temperature nitrogen gas which is ejected from the bottom of the processing chamber 61, allowing the processing chamber 61 to extinguish fires in the cabinet, greatly improving the safety performance of the smart vending machine during operation.

[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 interactive panel 30, through which the user scans a QR code to log in and selects a 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 product selection information and payment method selection 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. The corresponding conveyor belt 42 is activated according to the commodity information after payment, and the commodity is transported to the processing platform 45 as a commodity 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 goods to be picked up according to the reprocessing information.

[0092] During use, the user scans the QR code through the intelligent interactive panel 30, selects the designated beverage, and selects the corresponding reprocessing type according to his own needs. After payment is completed, the beverage on the designated conveyor belt 42 is transferred to the processing platform 45 at the front end. If heating is required, the package needs to be opened first to ensure that the heat can be effectively dissipated during the heating process, and then the reprocessing procedure is started to move the processing chamber 61 to the corresponding X-axis moving block 54, and the beverage is heated by microwaves through the microwave generating module 62; if cooling is required, the reprocessing procedure 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 circulation of air inside the processing chamber 61, low-temperature liquid nitrogen is injected to form low-temperature air, and the beverage is quickly cooled by the low-temperature air.

[0093] Regardless of whether it is during the reprocessing process of heating or cooling, the air circulation inside the processing chamber 61 is maintained to improve the reprocessing efficiency and effect. If multiple reprocessing is required, after the processing chamber 61 is removed, there is no need to turn off the fan 652, that is, the air circulation inside the processing chamber 61 is maintained, and the air curtain formed by the horizontal blowing port 632 and the horizontal exhaust port 641 is used to prevent the air inside the processing chamber 61 from overflowing. When reprocessing is performed again, the processing time can be effectively shortened, so that the beverage can be reprocessed continuously and efficiently.

[0094] The present invention can use the flexibly movable reprocessing device 60 to quickly perform designated reprocessing on designated commodities purchased by users according to the needs of each user, so as to meet the needs of different seasons and different groups of people, so that the smart vending cabinet no longer needs to continuously adjust and maintain the temperature inside the cabinet, which greatly reduces the investment and operation costs of the smart vending cabinet and saves energy.

[0095] By means of the airflow circulation mechanism, the built-in rack 63 and the built-in box 64 provided on the reprocessing device 60, the commodities can be reprocessed quickly and evenly, and can also be reprocessed continuously and efficiently.
