Description

Technical Field

[0001] The utility model relates to the technical field of automatic vending machines, and mainly relates to an anti-theft device for automatic vending machines and the automatic vending machine. Background Art

[0002] A vending machine is a machine that can automatically pay for goods according to the coins inserted. Vending machines are commonly used equipment for commercial automation. They are not restricted by time and place, can save manpower and facilitate transactions. It is a new form of commercial retail, also known as a 24-hour mini supermarket.

[0003] After opening the door of a traditional vending machine, the user can take out the goods from the cabinet. When closing the door, a switch, magnet or reed switch is used between the door and the cabinet to detect whether the door is closed. However, this detection method has great safety risks. Once people find out which specific detection device is used, they can use cheating methods. For example, a magnet can be placed close to the detection device to make the system mistakenly believe that the door is closed, but in fact the door is open. In this way, even if the goods in the cabinet are taken out, the system will not be able to know in time. Utility Model Content

[0047] The utility model provides a refrigeration device. In order to make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the protection scope of the utility model.

[0048] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0049] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0050] After opening the door of a traditional vending machine, the user can take out the goods from the cabinet. When closing the door, a switch, magnet or reed switch is used between the door and the cabinet to detect whether the door is closed. However, this detection method has great safety risks. Once people find out which specific detection device is used, they can use cheating methods. For example, a magnet can be placed close to the detection device to make the system mistakenly believe that the door is closed, but in fact the door is open. In this way, even if the goods in the cabinet are taken out, the system will not be able to know in time.

[0051] Based on this, the embodiment of the present application provides an anti-theft device for a vending machine and an automatic vending machine. By arranging multiple Hall sensors in conjunction with multiple magnets, the electromagnetic lock will not be triggered by cheating means, which can greatly improve the anti-theft performance of the vending machine.

[0052] Figure 1 This is a schematic diagram of the structure of a vending machine provided in one embodiment of the present application. Figure 1 The vending machine provided by the embodiment of the utility model may include a cabinet 1 and a cabinet door 2. The cabinet 1 has an opening, and the cabinet door 2 is installed on the cabinet 1 for opening or closing the opening of the cabinet 1, wherein a sealing strip (not shown in the figure) is provided at the gap between the cabinet 1 and the cabinet door 2 for sealing the gap.

[0053] The cabinet 1 may be in any suitable shape, such as a cube, a cuboid or a cylinder. An opening is provided on the front end surface of the cabinet 1, through which the cabinet 1 can communicate with the interior.

[0054] The cabinet door 2 can be hinged with the cabinet body 1 to form a hinge axis, and the cabinet door 2 can rotate around the hinge axis to open or close the opening. When the cabinet door 2 covers the cabinet body 1, the opening is closed. When the cabinet door 2 is rotated to other suitable positions, the opening is exposed. When the cabinet door 2 is rotated to a position covering the cabinet body 1, there is a gap between the cabinet door 2 and the cabinet body 1.

[0055] The cabinet door 2 can also be slidably connected to the cabinet body 1. For example, a sliding rail is set on the front end surface, and the cabinet door 2 is installed on the sliding rail and can slide along the sliding rail. When the cabinet door 2 slides to a first position along the sliding rail, the cabinet door 2 is closed on the cabinet body 1, and the opening is closed; when the cabinet door 2 slides to a second position along the sliding rail, the opening is exposed, and when the cabinet door 2 slides to the position covering the cabinet body 1, there is a gap between the cabinet door 2 and the cabinet body 1.

[0056] The cabinet door 2 can also be snap-connected with the cabinet body 1. When the cabinet door 2 is snap-connected with the cabinet body 1, the opening is closed, the cabinet door 2 covers the cabinet body 1, and there is a gap between the cabinet door 2 and the cabinet body 1; when the cabinet door 2 is removed from the cabinet body 1, the opening is exposed.

[0057] The sealing strip can be arranged on the cabinet body 1 or on the cabinet door 2 or any other suitable position. For example, the sealing strip can be fixed on the inner wall of the cabinet door 2. When the cabinet door 2 is closed on the cabinet body 1, the sealing strip can be engaged with the open side wall to achieve sealing. The sealing strip can also be manually inserted into the gap between the cabinet door 2 and the cabinet body 1 after the cabinet door 2 is closed on the cabinet body 1. When the cabinet door 2 needs to be opened, the sealing strip can be removed. After the gap between the cabinet door 2 and the cabinet body 1 is sealed by the sealing strip, the ability of the cabinet body to transfer heat with the outside through the gap can be reduced, and pollutants such as mosquitoes and dust can be prevented from entering the cabinet of the vending machine through the gap.

[0058] An opening is provided on the front face of the cabinet 1, and the front face is in the shape of a rectangular frame. The opening is connected to the interior of the cabinet 1, and goods can be replenished into the cabinet 1 through the opening, and equipment in the cabinet 1 can also be repaired.

[0059] The cabinet door 2 may include an upper end surface, a lower end surface, and a side end surface opposite to the hinged side, and correspondingly, the cabinet body 1 includes an upper inner wall, a lower inner wall, and a side inner wall opposite to the hinged side. When the cabinet door 2 closes the opening of the cabinet body 1, the upper inner wall of the cabinet body 1 contacts the upper end surface of the cabinet door 2, the lower inner wall of the cabinet body 1 contacts the lower end surface of the cabinet door 2, and the side inner wall of the cabinet body 1 contacts the side end surface of the cabinet door 2.

[0060] Reference Figure 2 , Figure 2 This is a first structural block diagram of an anti-theft device provided in an embodiment of the present application. Figure 2 As shown, the anti-theft device may include a Hall sensor 210, a detection device 220, a controller 230 and an electromagnetic lock 240. The Hall sensor 210 is electrically connected to the detection device 220, the detection device 220 is electrically connected to the controller 230, and the controller 230 is electrically connected to the electromagnetic lock 240. Among them, the Hall sensor 210 can generate a corresponding sensing signal when the cabinet door 2 closes the opening of the cabinet body 1. The detection device 220 can detect the sensing signal and transmit it to the controller 230. After receiving the sensing signal, the controller 230 can verify whether the sensing signal is the same as the preset locking signal. If the sensing signal is the same as the preset locking signal, it can be determined that the sensing signal is a locking signal. At this time, the controller 230 can send a locking command to the electromagnetic lock 240, so that the electromagnetic lock locks the cabinet door 2 to the cabinet body 1 after receiving the locking command.

[0061] The Hall sensor device 210 includes a plurality of Hall sensors 211 and a plurality of magnets 212. The plurality of Hall sensors 211 are arranged on the cabinet 1, and the plurality of magnets 212 are arranged on the cabinet door 2. The number of magnets 212 is the same as the number of Hall sensors 211. If the number of Hall sensors 211 is 5, the number of magnets 212 is also 5. Each magnet 212 is arranged in one-to-one correspondence with each Hall sensor 211.

[0062] In some embodiments, reference Figure 3 , Figure 3 The first schematic diagram of the arrangement positions of multiple Hall sensors and multiple magnets provided in one embodiment of the present application. Figure 3 As shown, multiple Hall sensors 211 can be arranged on the upper inner wall 101 of the cabinet 1 and arranged in a row. Correspondingly, multiple magnets 212 can be arranged on the upper end surface 201 of the cabinet door 2. And the multiple magnets 212 are arranged one by one with the multiple Hall sensors 211. Figure 4 , Figure 4 It is a schematic diagram of the corresponding arrangement of multiple Hall sensors and multiple magnets. The number of Hall sensors can be set to 5, including Hall sensor 1, Hall sensor 2, Hall sensor 3, Hall sensor 4, and Hall sensor 5. Correspondingly, the number of magnets can be set to 5, including magnet 1, magnet 2, magnet 3, magnet 4, and magnet 5. Among them, when the cabinet door 2 closes the opening of the cabinet 1, that is, when multiple magnets are close to multiple Hall sensors, the S pole of magnet 1 is close to Hall sensor 1, the N pole of magnet 2 is close to Hall sensor 2, the S pole of magnet 3 is close to Hall sensor 3, the N pole of magnet 4 is close to Hall sensor 4, and the S pole of magnet 5 is close to Hall sensor 5. That is, the order of the magnet induction poles is set to SNSNS.

[0063] It should be noted that the number of Hall sensors and magnets is the same, and the embodiment of the present application does not limit the number of Hall sensors and magnets, which can be 2, 3, 4, 5, 6, 7, 10, etc. The embodiment of the present application also does not limit the order of the induction poles of the magnets. If the number of Hall sensors and magnets is set to 5, the 5 magnets can be arranged in different combinations according to the N pole and S pole, with a total of 30 combinations (excluding all N poles and all S poles), and can be randomly set according to these 30 combinations.

[0064] Five magnets correspond to five Hall elements. When setting, the sensing parameters of the five magnets corresponding to the five Hall elements when the power is turned on for the first time can be determined as the locking condition, and any other arrangement and combination of magnets cannot unlock. For example, if the initial sensing pole sequence of the five magnets is NSNSN, the corresponding sensing signal is a high-low-high-low-high level signal. At this time, other combinations except NSNSN (i.e., sensing signals other than high-low-high-low-high) cannot form locking trigger conditions.

[0065] In some embodiments, a plurality of Hall sensors 211 may be disposed on the lower inner wall of the cabinet 1 and arranged in a row. Correspondingly, a plurality of magnets 212 are disposed on the lower end surface of the cabinet door 2. The plurality of magnets 212 and the plurality of Hall sensors 211 are disposed one-to-one in correspondence. When the cabinet door 2 closes the opening of the cabinet 1, corresponding induction signals may be generated between the plurality of magnets 212 and the plurality of Hall sensors 211.

[0066] In some embodiments, reference Figure 5 , Figure 5 A second schematic diagram of the setting positions of multiple Hall sensors and multiple magnets provided in one embodiment of the present application. Multiple Hall sensors 211 are arranged on the side inner wall 102 of the cabinet 1 and are arranged in a row. Correspondingly, multiple magnets 212 are arranged on the side end surface 202 of the cabinet door 2. And the multiple magnets 212 are arranged one-to-one with the multiple Hall sensors 211. When the cabinet door 2 closes the opening of the cabinet 1, corresponding induction signals can be generated between the multiple magnets 212 and the multiple Hall sensors 211.

[0067] The detection device 220 is electrically connected to each Hall sensor 211, so that the detection device 220 can detect the induction signals between the multiple Hall sensors 211 and the multiple magnets 212. Specifically, when the S pole of the magnet 212 is close to the corresponding Hall sensor, the output pin of the corresponding Hall sensor 211 outputs a low level. When the N pole of the magnet 212 is close to the corresponding Hall sensor or the magnet 212 is far away from the corresponding Hall sensor 211, the output pin of the corresponding Hall sensor 211 outputs a high level. Therefore, the detection device can detect the induction signals between the multiple Hall sensors 211 and the multiple magnets 212.

[0068] For example, Figure 4The arrangement of multiple Hall sensors and multiple magnets shown in the figure is taken as an example. When the cabinet door 2 closes the opening of the cabinet body 1, that is, when multiple magnets are close to multiple Hall sensors, since the S pole of magnet 1 is close to Hall sensor 1, the detection device 220 can detect that the signal output by the output pin of Hall sensor 1 is a low level signal. Since the N pole of magnet 2 is close to Hall sensor 2, the detection device 220 can detect that the signal output by the output pin of Hall sensor 2 is a high level signal. Since the S pole of magnet 3 is close to Hall sensor 3, the detection device 220 can detect that the signal output by the output pin of Hall sensor 3 is a low level signal. Since the N pole of magnet 4 is close to Hall sensor 4, the detection device 220 can detect that the signal output by the output pin of Hall sensor 4 is a high level signal. Since the S pole of magnet 5 is close to Hall sensor 5, the detection device 220 can detect that the signal output by the output pin of Hall sensor 5 is a low level signal. That is, the detection device 220 can detect a low-high-low-high-low level signal.

[0069] The controller 230 is electrically connected to the detection device 220, so that the controller 230 can receive the sensing signal detected by the detection device 220. A locking signal is pre-written in the controller 230, so that after receiving the sensing signal, the controller 230 can verify whether the sensing signal is the pre-written locking signal, and if so, determine that the sensing signal is a locking signal, generate a locking instruction and send it to the electromagnetic lock 240, so that the electromagnetic lock 240 locks the cabinet door 2 to the cabinet body 1 based on the locking instruction.

[0070] For example, Figure 4 The arrangement of multiple Hall sensors and multiple magnets shown in FIG. 2 is taken as an example. The detection device 220 can detect a low-high-low-high-low level signal and transmit it to the controller 230. After receiving the low-high-low-high-low level signal, the controller 230 verifies whether the signal is consistent with the pre-written lock signal. If consistent, the controller generates a lock command and sends it to the electromagnetic lock 240. After receiving the lock command, the electromagnetic lock 240 can lock the cabinet door 2 to the cabinet body 1.

[0071] In the embodiment of the present application, the controller 230 may be a micro control unit (MCU). Figure 6 , Figure 6 This is a schematic diagram of the circuit principle of the anti-theft device provided in one embodiment of the present application. Figure 6As shown, the Hall sensing device 210 includes a plurality of Hall sensors and a plurality of magnets. Each magnet is arranged in a one-to-one correspondence with each Hall sensor. The detection device 220 includes a plurality of input ports, and the plurality of input ports are electrically connected to the corresponding Hall sensors respectively to receive the level signals output by the Hall sensors. The detection device 220 also includes a plurality of output ports, and the plurality of output ports are connected to the MCU respectively to transmit the received level signals output by each Hall sensor to the MCU. After receiving the level signals output by each Hall sensor, the MCU can verify whether the combination of each level signal is consistent with the preset locking signal. If consistent, the MCU will generate a locking instruction and send it to the electromagnetic lock 240, so that the electromagnetic lock 240 can lock the cabinet door 2 to the cabinet body 1.

[0072] In some embodiments, reference Figure 7 , Figure 7 This is a second structural block diagram of an anti-theft device provided in an embodiment of the present application. Figure 7 As shown, the anti-theft device may include a Hall sensor 210, a detection device 220, a controller 230 and an electromagnetic lock 240. The Hall sensor 210 is electrically connected to the detection device 220, the detection device 220 is electrically connected to the controller 230, and the controller 230 is electrically connected to the electromagnetic lock 240. Among them, the Hall sensor 210 includes a plurality of Hall sensors and a plurality of magnets. Each magnet is arranged in a one-to-one correspondence with each Hall sensor. The Hall sensor 210 can generate a corresponding sensing signal when the cabinet door 2 closes the opening of the cabinet body 1. The detection device 220 can detect the sensing signal and transmit it to the controller 230. After receiving the sensing signal, the controller 230 can verify whether the sensing signal is the same as the preset locking signal. If the sensing signal is the same as the preset locking signal, it can be determined that the sensing signal is a locking signal. At this time, the controller 230 can send a locking command to the electromagnetic lock 240, so that the electromagnetic lock locks the cabinet door 2 to the cabinet body 1 after receiving the locking command. The anti-theft device may further include an alarm device 250, which may be disposed on the cabinet 1. The alarm device 250 may be electrically connected to the controller 230, and the alarm device 250 is configured to issue a prompt alarm based on a control signal sent by the controller. Specifically, when the controller 230 verifies that the combination of level signals output by each Hall sensor sent by the detection device 220 is inconsistent with the lock signal, the controller 230 will send a control signal to the alarm device 250, so that the alarm device 250 can issue an alarm after receiving the control signal to deter theft.

[0073] It should be noted that the alarm device 250 can issue an alarm prompt by displaying a preset light message through its configured warning light. The alarm device 250 can also issue an alarm prompt by playing a preset voice message through its configured voice module. The alarm device 250 can also issue an alarm prompt by combining displaying a warning light and playing voice.

[0074] In some embodiments, the alarm device 250 may include a light alarm module. The light alarm module may be disposed in the cabinet 1 or the cabinet door 2. The light alarm module is configured to emit a flashing light to give an alarm based on a control signal sent by the controller 230.

[0075] In the embodiment of the present application, the controller 230 is connected to the light alarm module. When the controller 230 determines that the sensing signal sent by the detection device 220 is inconsistent with the preset lock signal, the controller 230 will send an alarm control signal to the light alarm module. After receiving the alarm control signal sent by the controller 230, the light alarm module will control the flashing light to warn that the current theft behavior has been recorded and known, thereby deterring the thief from stealing.

[0076] In some embodiments, the alarm device 250 may include a buzzer alarm module. The buzzer alarm module may be disposed in the cabinet 1 or the cabinet door 2. The present application does not limit the specific location of the buzzer alarm module. The buzzer alarm module is configured to emit an audible and visual signal to alarm based on a control signal sent by the controller 230.

[0077] In the embodiment of the present application, the controller 230 is connected to the buzzer alarm module. When the controller 230 determines that the sensing signal sent by the detection device 220 is inconsistent with the preset lock signal, the controller 230 will send an alarm control signal to the buzzer alarm module. After receiving the alarm control signal sent by the controller 230, the buzzer alarm module will control the emission of sound and light signals to alarm, so as to warn that the current theft behavior has been recorded and known, thereby deterring the thief from stealing.

[0078] The alarm device 250 may include a voice module. The voice module may be disposed in the cabinet 1 or the cabinet door 2. The present application does not limit the specific location of the voice module 53. The voice module 53 is configured to send a prompt voice based on the control signal sent by the controller 230 to perform an alarm.

[0079] In the embodiment of the present application, the controller 230 is connected to the voice module. When the controller 230 determines that the sensing signal sent by the detection device 220 is inconsistent with the preset locking signal, the controller 230 will send an alarm control signal to the voice module. After receiving the alarm control instruction sent by the controller 230, the voice module will control the issuance of a preset voice prompt message for alarm. For example, the voice module can issue a voice message of "Hello, please stop your attempt to steal immediately". At the same time, the information can be transmitted back to the background for alarm.

[0080] In some embodiments, the electromagnetic lock 240 is disposed on the cabinet body 1, and the cabinet door 2 is provided with a lock catch 241 that cooperates with the electromagnetic lock 240.
