[0002] Vending machines are self-service devices that require no human intervention and can automatically sell goods through methods such as coin insertion, barcode scanning, or facial recognition. They are like mini supermarkets that operate 24 hours a day, mainly selling standardized goods such as beverages, snacks, and daily necessities. They are particularly convenient to place in places such as shopping malls, schools, and train stations.

[0003] An automatic vending machine is disclosed in Chinese Patent No. CN222071278U. The vending machine includes a casing, a dry ingredient storage mechanism, and a wet ingredient storage mechanism. At least a portion of the internal space of the casing is divided into a first receiving cavity and a second receiving cavity. The dry ingredient storage mechanism is located in the first receiving cavity. The wet ingredient storage mechanism is located in the second receiving cavity. In this disclosure, the dry ingredient storage mechanism and the wet ingredient storage mechanism are respectively located in the first receiving cavity and the second receiving cavity, achieving separate storage. This helps maintain the dryness of the first receiving cavity, thereby maintaining the dryness of the dry ingredients, reducing the impact of moisture absorption on the taste of the finished product, and also helps extend the shelf life of the dry ingredients.

[0004] Existing vending machines are prone to theft because they are often used in the external environment. Therefore, an anti-theft vending machine is proposed to address this problem. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve at least one of the technical problems mentioned in the background art, this utility model proposes an anti-theft automatic vending machine.

Connecting block 12 is fixedly connected to spring 11 via snap-fit ​​body 8. Connector 13 is fixedly connected to the bottom of connecting block 12, and iron block 14 is fixedly connected to the top of connecting block 12. Electromagnetic generator 15 is installed on the inner top wall of snap-fit ​​body 8. Through the setting of electromagnetic generator 15, after being powered, electromagnetic generator 15 can use the principle of electromagnetism to attract iron block 14, thereby driving connecting block 12 and connector 13 to rise, so that cabinet door 4 can be opened for restocking. At the same time, when connector 13 descends, when cabinet door 4 is pulled by the outside, snap-fit ​​body 8 will drive movable hook 19 to move and abut against trigger switch 20, thereby triggering trigger switch 20, so that sound and light alarm 6 is activated and an alarm is generated.

[0027] Reference Figure 2 and Figure 6 An air groove 24 is provided on the inner surface of the freezer body 1. A piston strip 25 is slidably connected to the inner surface of the freezer body 1. A rubber pad 26 is fixedly connected to one side of the piston strip 25. Through the air groove 24, the piston strip 25 can slide inside the freezer body 1, and the rubber pad 26 can play an auxiliary sealing role after contacting the cabinet door 4.

[0028] Reference Figure 2 and Figure 6An air pump 21 is installed on the top of the freezer body 1. The output end of the air pump 21 is connected to an air supply pipe 22. The air supply pipe 22 is connected to the top of the freezer body 1. The air pump 21 is set so that after the air pump 21 is started, it draws gas into the interior of the freezer body 1, causing the air pressure in the air tank 24 to rise, thereby pushing the rubber pad 26 to abut against the cabinet door 4.

[0029] Reference Figure 2 and Figure 6 The input end of the air pump 21 is connected to the exhaust pipe 23, which is connected to the top of the freezer body 1. Through the exhaust pipe 23, the air pump 21 can extract the gas inside the air tank 24, making it convenient to open the cabinet door 4.

[0030] Reference Figure 1 and Figure 2 The main body 1 of the freezer has a discharge port 2 on one side and a control panel 3 on the other side. The discharge port 2 is designed to allow the product to be removed.

[0031] Reference Figure 1 and Figure 2 A cabinet door 4 is rotatably connected to one side of the main body 1 of the freezer. A material plate 7 is installed on the inner wall of the main body 1 of the freezer. The cabinet door 4 allows staff to easily replenish goods and makes it convenient for buyers to observe.

[0032] Reference Figure 1 and Figure 2 The model of the sound and light alarm 6 is PATLITE ADC-24R-G, and the model of the trigger switch 20 is IFM PN7095. By setting the sound and light alarm 6, the sound and light alarm 6 is put into a network-enabled state, so that the sound and light alarm 6 can also provide remote reminders after it sounds an alarm.

[0033] Working principle: The electromagnetic generator 15, when powered, attracts the iron block 14 using the principle of electromagnetism, causing the connecting block 12 and connector 13 to rise, allowing the cabinet door 4 to open for restocking. Simultaneously, when the connector 13 descends, the cabinet door 4, when pulled by the outside, causes the locking body 8 to move the movable hook 19, which then abuts against the trigger switch 20. This triggers the audible and visual alarm 6, activating it. The air groove 24 allows the piston strip 25 to slide inside the freezer body 1, and the rubber pad 26 provides an auxiliary seal upon contact with the cabinet door 4. The system is equipped with an air pump 21, which, upon startup, draws gas into the interior of the freezer body 1, causing the air pressure in the air tank 24 to rise. This, in turn, pushes the rubber pad 26 against the cabinet door 4. The exhaust pipe 23 allows the air pump 21 to remove the gas from the air tank 24, facilitating the opening of the cabinet door 4. The discharge port 2 allows for the removal of goods. The cabinet door 4 allows staff to easily replenish goods and facilitates customer inspection. The sound and light alarm 6 is network-enabled, enabling remote alerts after the alarm sounds.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
