By heating the membrane, the membrane shrinks and wraps the protected goods inside the outer shell.
[0014] A method for preventing counterfeiting using this anti-counterfeiting device is also provided, the specific method being as follows:
[0015] S1. Place the identified protected product on the base, align the insertion direction indicator arrow on the outer shell with the insertion direction mark on the base, and guide the outer shell into the gap between the outer and inner side walls of the base shell through the guide groove on the outer shell and the insertion guide strip on the outer side wall of the base shell. During insertion, the lower edge of the outer shell contacts the spring-loaded limit sliding block on the disposable spring-loaded buckle, forcing the spring-loaded limit sliding block to move backward. The buckle structure is locked in the groove of the first limit block. The spring-loaded limit sliding block presses down on the touch switch, and the touch switch signal is fed back to the security encryption chip. The outer shell continues to be inserted downward, and the lower edge of the outer shell contacts and presses down on the disposable spring-loaded buckle, forcing the disposable spring-loaded buckle to move backward until the disposable spring-loaded buckle is fully pressed down to the limit structure position on the outer shell. At this time, the spring-loaded buckle movement spring pushes the disposable spring-loaded buckle forward, so that the disposable spring-loaded buckle moves into the limit structure, thereby completing the locking and limiting of the outer shell. At this time, the touch switch is in the non-initial state, and the slide switch is in the initial state, indicating that the limit structure on the outer shell and the disposable spring-loaded buckle are locked, and the anti-counterfeiting device has not been activated and released.
[0016] S2. The authenticator inputs real-name authentication or biometric information through a handheld communication device via a human-computer interaction interface. This information is then compared with the authenticator's registration information on the product manufacturer's PC management platform and the cloud encrypted database. Upon successful verification, login is granted. The anti-counterfeiting device, the authenticator's handheld communication device via the human-computer interaction interface, the product manufacturer's PC management platform, and the cloud encrypted database maintain a continuous encrypted data connection. The authenticator inputs authentication information into the product manufacturer's PC management platform and the cloud encrypted database. The secure encryption chip and the product manufacturer's PC management platform and the cloud encrypted database undergo asymmetric encryption and decryption for bidirectional confirmation. The product manufacturer's PC-side management platform and cloud encrypted database obtain the state of the sliding switch and touch switch transmitted by the secure encryption chip. At this time, the sliding switch is in the initial state, indicating that it is not released, and the touch switch is in the non-initial state. Under these circumstances, the product manufacturer's PC-side management platform and cloud encrypted database allow the appraiser to input the appraisal information data into the product manufacturer's PC-side management platform and cloud encrypted database. After the appraiser has input the appraisal information data, the appraisal data is solidified through real-name authentication and / or biometric identification and digital signature, and then uploaded to the product manufacturer's PC-side management platform and cloud encrypted database. At this point, the appraisal information data cannot be changed.
[0017] S3. The anti-counterfeiting verification process involves the user establishing an encrypted data link between the handheld communication device via the human-machine interface, the manufacturer's PC management platform, the cloud encrypted database, and the anti-counterfeiting device. The encrypted data queue containing the security encryption chip ID and communication chip ID of the anti-counterfeiting device is then uploaded. The verification information is bound to the anti-counterfeiting device and the verified genuine product, forming a one-to-one correspondence. The user can power the PCB circuit board via an external power interface, wireless power, or an internal battery. After power is supplied, the security encryption chip checks the position and status of the sliding and touch switches. The security encryption chip establishes an encrypted data link with the manufacturer's PC management platform and the cloud encrypted database (public and private keys) through the communication chip for asymmetric encryption and decryption mutual verification. Both parties confirm valid and legitimate identities. If the communication chip is a remote communication chip, the anti-counterfeiting device directly connects to the manufacturer's PC management platform and the cloud encrypted database. If the communication chip is a short-range communication chip, it connects to the user's handheld communication device via the human-machine interface before connecting to the manufacturer's PC management platform and the cloud encrypted database. The user sends a verification request to the manufacturer's PC management platform and cloud encrypted database via a handheld communication device through the human-computer interaction interface. The manufacturer's PC management platform and cloud encrypted database issue an asymmetric encrypted dynamic code. After the security encryption chip on the anti-counterfeiting device's PCB circuit board decrypts the code, it is displayed on the screen. The user's handheld communication device also displays the code simultaneously. The user determines the authenticity and validity of the protected product by comparing the dynamic code displayed on the handheld communication device with the dynamic code displayed on the anti-counterfeiting device's screen. Because the genuine product is locked and protected by the anti-counterfeiting device after authentication, the authentication information remains valid and unique until the device is opened and released. In subsequent multiple transactions, the user only needs to power the anti-counterfeiting device, establishing an encrypted data link between the user's handheld communication device, the manufacturer's PC management platform and cloud encrypted database, and the anti-counterfeiting device. The user then receives the encrypted authentication information data issued by the manufacturer's PC management platform and cloud encrypted database, eliminating the need for repeated authentication.
[0018] S4. Anti-counterfeiting verification: The user sends an unlocking / release request to the manufacturer's PC management platform and cloud encrypted database via a handheld communication device through the human-computer interaction interface. The manufacturer's PC management platform and cloud encrypted database issue an asymmetric encryption unlocking / release command. The security encryption chip on the anti-counterfeiting device's PCB circuit board receives the asymmetric encryption command through the communication chip, performs encryption and decryption authentication, and confirms its legitimacy. After confirmation, the security encryption chip on the PCB circuit board controls the power control circuit to supply power to the heating element. The heating element heats up and melts the low-temperature fusible metal pillar, releasing the swing arm's restriction. The unlocking motion spring pushes the sleeve to move backward, and the sleeve drives the sliding switch to move. At this time, the disposable snap-on snap-on also moves backward through the lower limit block of the disposable snap-on snap-on, thus causing the disposable snap-on snap-on and the snap-on snap-on limit sliding block to disengage from the limiting structure on the outer shell. The casing can then be removed from the differential limiting structure, allowing the user to obtain the protected product. Alternatively, the user can use an external heat source to heat the low-temperature fusible metal fixing rivets on the back of the base. These rivets, through a low-temperature fusible metal fixing ring, conduct heat to the low-temperature fusible metal pillar, melting it and thus obtaining the protected product. The security encryption chip automatically detects the position of the sliding switch. If the switch is not in its initial state, the switch signal is fed back to the security encryption chip. The chip then communicates with the product manufacturer's PC management platform and cloud encryption database via a communication chip, indicating that the anti-counterfeiting device has been activated. The product manufacturer's PC management platform and cloud encryption database automatically close the anti-counterfeiting device's data queue, and the anti-counterfeiting device automatically executes the security encryption chip's self-destruct procedure.
[0019] Compared with the prior art, the advantages of this invention are:
[0020] 1. This invention is a one-time mechanical lock. The limiting structure of the outer shell of the anti-counterfeiting device can only be inserted into the chassis of the anti-counterfeiting device once. When the limiting structure of the outer shell of the anti-counterfeiting device is inserted into the chassis, the non-rebound limiting component on the differential limiting structure inside the chassis will retract and push open the upper and lower limiting springs. Subsequently, the upper and lower limiting springs fall back to their original positions, preventing the non-rebound limiting component on the differential limiting structure from retracting. At the same time, the rebound limiting component on the differential limiting structure cannot retract either. This causes the rebound limiting component on the differential limiting structure to be subjected to spring force, allowing it to only perform a one-time backward rebound reset movement. As a result, the outer shell of the anti-counterfeiting device that has already been inserted into the chassis is damaged, and a new outer shell cannot be inserted into the chassis a second time.
[0021] 2. The present invention has a sophisticated structural design, small size, low cost, and high reliability;
[0022] 3. This invention uses a purely physical opening method, which can unlock the outer shell by heating. The low-melting-point fusible metal fixing ring on the anti-counterfeiting device is made of a heat-conducting material, and this fixing ring is fixed to the anti-counterfeiting device by a heat-conducting material fixing component, which penetrates to the outside of the anti-counterfeiting device's chassis outer shell. Therefore, consumers can also heat this heat-conducting material fixing component, and the heat is conducted to the low-melting-point fusible metal fixing ring, causing the low-melting-point fusible metal to undergo an instantaneous physical phase change from solid to liquid. This makes the breaking strength of the low-melting-point fusible metal lower than the spring thrust of the anti-counterfeiting device's release mechanism, thus causing the low-melting-point fusible metal to break. The anti-counterfeiting device's release mechanism can then move, causing the differential limiting structure inside the anti-counterfeiting device's chassis to retract, allowing the upper outer shell of the anti-counterfeiting device to detach from the anti-counterfeiting device's chassis. Consumers can then detach the upper outer shell of the anti-counterfeiting device from the chassis, thus obtaining the protected product wrapped between the upper outer shell and the chassis of the anti-counterfeiting device.
[0023] 4. The mechanical structure works in conjunction with the chip, transmitting the device's status to the communication chip via touch and slide switches, and sending signals to the terminal via the security encryption chip and communication chip, resulting in strong anti-counterfeiting capabilities and high difficulty in cracking;
[0024] 5. The human-computer interaction interface handheld communication device, the product manufacturer's PC management platform, the cloud encrypted database, and the anti-counterfeiting device form an encrypted data link network. The encrypted data queue of the authentication information data finally uploaded by the anti-counterfeiting verification user contains the security encryption chip ID of the anti-counterfeiting device and the communication chip ID. The authentication information data is bound to the anti-counterfeiting device and the genuine product after authentication, forming a one-to-one correspondence, forming multiple insurances and increasing the anti-counterfeiting strength.

[0060] The invention will be further described below with reference to the accompanying drawings. The structure and principle of the invention are very clear to those skilled in the art. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention.
[0061] like Figure 1-5 As shown in Figure 12, the base 24 of the present invention has a limiting through hole 25 on its side wall. A differential limiting structure 26 is provided inside the limiting through hole 25 of the base 24. The base 24 is provided with a shell 12, and the shell 12 is provided with a limiting structure 13. The shell 12 is connected to the differential limiting structure 26 inside the base 24 in one step through the limiting structure 13. The shell 12 is provided with a guide groove 27. The shell 12 is connected to the base 24 in one step through the limiting structure 13 and the guide groove 27. The shell 12 is also provided with an insertion direction indicator arrow 28.
[0062] like Figure 11 , 15 As shown, the differential limiting structure 26 mainly consists of a sleeve 1, a disposable spring buckle 2, a spring buckle limiting sliding block 3, and a spring buckle movement spring 4. Figure 16 , 17 As shown, the sleeve 1 has a cavity at the front end and an extension at the rear end. A limiting spring 5 is provided at the top or bottom of the cavity. The front end of the limiting spring 5 is connected to the sleeve 1. The rear end of the limiting spring 5 has a protruding buckle structure 10. A limiting hole is opened at the bottom of the sleeve 1. The sleeve 1 is connected to the mounting base 15 fixed to the base 24 through the unlocking motion spring 14.
[0063] like Figure 16 , 17 As shown, the disposable snap fastener 2 is located in the cavity of the sleeve 1. The front end of the disposable snap fastener 2 is provided with several inclined surfaces. The rear end of the disposable snap fastener 2 is connected to the inner wall of the cavity of the sleeve 1 through the snap fastener movement spring 4. The snap fastener movement spring 4 provides the forward restoring force of the disposable snap fastener 2. The upper surface of the disposable snap fastener 2 is provided with a groove. The lower side of the disposable snap fastener 2 is also provided with a limiting block 16. The limiting block 16 is located in the limiting hole at the bottom of the sleeve 1. When the sleeve 1 moves backward, it drives the limiting block 16 to move, thereby driving the disposable snap fastener 2 to move backward. The groove of the disposable snap fastener 2 is provided with a first step structure 11.
[0064] like Figure 16 , 17 As shown, the snap-lock limiting sliding block 3 is set on the top of the disposable snap-lock 2 and located in the groove of the disposable snap-lock 2. The width of the groove of the disposable snap-lock 2 in the front-to-back direction is greater than the width of the snap-lock limiting sliding block 3, so that the snap-lock limiting sliding block 3 can move within a set distance of the groove of the disposable snap-lock 2. The front end of the snap-lock limiting sliding block 3 is provided with several inclined surfaces, and the inclined surfaces of the snap-lock limiting sliding block 3 are higher than the inclined surfaces of the disposable snap-lock 2. The rear end of the snap-lock limiting sliding block 3 is provided with at least one protruding first limiting block 6. The upper and lower sides of the first limiting block 6 are provided with protrusions with inclined surfaces. The front end of the protruding part of the first limiting block 6 is provided with a groove 7. The first limiting block 6 and the groove 7 at the front end of the first limiting block 6 cooperate with the buckling structure 10. When the snap-lock limiting sliding block 3 moves to the rear, the buckling structure 10 deforms outward along the inclined surface of the protrusion and is locked in the groove 7 of the first limiting block 6, restricting the movement of the snap-lock limiting sliding block 3. The first limiting block 6 of the snap-lock limiting sliding block 3 moves backward, and its rear end can abut against the inner wall of the sleeve 1 cavity. A touch switch support arm 8 is also provided at the rear end of the first limiting block 6, which cooperates with the touch switch 9.

[0071] like Figure 10 , 14 As shown, the base 24 is also equipped with a PCB circuit board 43. The PCB circuit board 43 is sleeved on the bottom base 30 of the swing arm central shaft at the center of the base shell 29 through the central opening 44. The PCB circuit board 43 is equipped with a display screen 45 and an external power socket 46. The PCB circuit board 43 is also equipped with a slide switch 17, a touch switch 9, a heating element 47, a communication antenna 48, a communication chip 49, and a security encryption chip 50. The communication chip 49 transmits signals through the communication antenna 48. The slide switch 17 and the touch switch 9 are electrically connected to the security encryption chip 50. The security encryption chip 50 receives and transmits signals through the communication chip 49. The security encryption chip 50 controls the power control circuit to supply power to the heating element 47.
[0072] like Figure 6 , 7 As shown, the outer and inner sidewalls of the base shell 29 are provided with an external power socket opening 51 and a display window opening 52, respectively. Figure 8 , 9 As shown, the side wall of the base cover 35 is respectively provided with an external power socket opening groove 53 and a display window opening groove 54 that mate with the external power socket opening 51 and the display window opening 52 of the base shell 29; Figure 2 , 3 As shown, the outer casing 12 is provided with an external power plug through hole 55, which mates with the external power socket opening 51 and the external power socket opening groove 53.
[0073] like Figure 12As shown, the display screen 45 on the PCB circuit board 43 is located in the display window opening 52 and the display window opening groove 54, and the external power socket 46 is located in the external power plug through hole 55, the external power socket opening 51 and the external power socket opening groove 53.
[0074] The outer casing 12 can be a hard outer casing 12 or a soft outer casing 12, such as Figure 26 , 27 As shown, when the outer casing 12 is a rigid casing, the outer casing 12 is sealed or the top of the outer casing 12 is provided with a vent hole 56, and a waterproof and breathable membrane 57 is provided below the vent hole 56; as Figure 28 , 29 As shown, when the outer shell 12 is a soft outer shell, the outer shell 12 is connected to the film 59 via the film retaining ring 58, and the film 59 is embedded between the outer shell 12 and the film retaining ring 58. Figure 30 , 31 As shown in Figure 32, the upper cover 35 of the base is provided with an upper one-way valve through hole 60, and the bottom shell 29 of the base is provided with a lower one-way valve through hole 61, a one-way valve fixing base 62, and a one-way valve 63 on the one-way valve fixing base 62. Figure 33 , 34 As shown, by heating the film 59, the film 59 shrinks and wraps the protected product 64 inside the outer shell 12.
[0075] like Figure 16-24 As shown, the working principle of the differential limiting structure 26 of the present invention is as follows: First, the unlocking motion spring 14 abuts against the mounting base 15, and then the swing arm 18 is connected to the low-temperature fusible metal fixing rivet 22. The swing arm 18 abuts against the extension of the sleeve 1, thereby pressing the unlocking motion spring 14 to complete the installation of the differential limiting structure 26. The protected product 64 is placed in the base 24, and then the outer shell 12 is covered. The outer shell 12 moves from top to bottom from the head of the differential limiting structure 26. Because the inclined surface of the snap-lock limiting sliding block 3 is higher than the inclined surface of the disposable snap-lock 2, the bottom of the outer shell 12 contacts the snap-lock limiting sliding block 3 first, so the snap-lock limiting sliding block 3 moves backward. The first limiting block 6 on the snap-lock limiting sliding block 3 moves backward, pushing the limiting spring piece 5 on the sleeve 1 to deform outward. The outer shell 12 continues to move downward until the buckle structure 10 on the limiting spring piece 5 of the sleeve 1 falls into the groove 7. At this time, the touch switch 9 is in the pressed state. As the outer shell 12 continues to move downward, the bottom of the outer shell 12 begins to contact and press down on the disposable snap-on 2, causing the disposable snap-on 2 to move backward. The snap-on movement spring 4 is compressed, and the outer shell 12 continues to move downward until the disposable snap-on 2 and the snap-on limiting sliding block 3 are pressed down to the position of the limiting structure 13 on the outer shell 12. Because the snap-on movement spring 4 of the disposable snap-on 2 is no longer restricted, the snap-on movement spring 4 pushes the disposable snap-on 2 forward, thereby causing the disposable snap-on 2 to move into the limiting structure 13, thus completing the locking and limiting of the outer shell 12.
[0076] When unlocking is required, simply heat the cryogenic fusible metal pillar 19. The pillar melts upon heating, freeing the unlocking spring 14 from the constraint of the swing arm 18. This causes the sleeve 1 to move backward, which in turn moves the sliding switch 17. The sleeve 1, through the lower limiting block 16 of the disposable snap-on 2, also moves the snap-on 2 backward, disengaging it and the snap-on limiting sliding block 3 from the limiting structure 13 on the outer shell 12. The outer shell 12 can then be removed from the differential limiting structure 26 within the base 24. Because the snap-on structure 10 has fallen into the groove and cannot be reset, the differential limiting structure 26 cannot be used after the outer shell 12 has been locked and unlocked, and therefore cannot continue to lock the outer shell 12.
[0077] like Figure 25 As shown, by placing the protected item 64 between the outer casing 12 and the base 24, the item being inspected can be protected. The specific method is as follows:
[0078] S1. Place the identified protected product 64 on the base 24, align the insertion direction indicator arrow 28 on the outer shell 12 with the insertion direction mark 33 on the base 24, and guide the outer shell 12 into the gap between the outer ring side wall and the inner ring side wall of the base shell 29 by the cooperation of the guide groove 27 of the outer shell 12 and the insertion guide strip 32 on the outer ring side wall of the base shell 29.
[0079] During insertion, the lower edge of the outer shell 12 contacts the snap-locking sliding block 3 on the disposable snap-lock 2, forcing the snap-locking sliding block 3 to move backward. The snap-locking structure 10 is engaged in the groove of the first limiting block 6. The snap-locking sliding block 3 presses down on the touch switch 9, and the touch switch 9 sends a signal to the security encryption chip 50. The outer shell 12 continues to be inserted downward, and the lower edge of the outer shell 12 contacts and presses down on the disposable snap-lock 2, forcing the disposable snap-lock 2 to move backward until the disposable snap-lock 2 is completely pressed down to the position of the limiting structure 13 on the outer shell 12. At this time, the snap-locking spring 4 pushes the disposable snap-lock 2 forward, so that the disposable snap-lock 2 moves into the limiting structure 13, thereby completing the locking and limiting of the outer shell 12. At this time, the touch switch 9 is in the non-initial state, and the sliding switch 17 is in the initial state, indicating that the limiting structure 13 on the outer shell 12 is locked with the disposable snap-lock 2, and the anti-counterfeiting device has not been opened and released.
[0080] S2. The authenticator inputs real-name authentication or biometric information through a handheld communication device via a human-computer interaction interface. This information is then compared with the authenticator's registration information on the product manufacturer's PC management platform and the cloud encrypted database. Upon successful verification, login is granted. The anti-counterfeiting device, the authenticator's handheld communication device via the human-computer interaction interface, the product manufacturer's PC management platform, and the cloud encrypted database maintain a continuous encrypted data connection. The authenticator inputs authentication information into the product manufacturer's PC management platform and the cloud encrypted database. The secure encryption chip 50 and the product manufacturer's PC management platform and the cloud encrypted database undergo asymmetric encryption and decryption for bidirectional confirmation. The manufacturer's PC management platform and cloud encrypted database obtain the states of the slide switch 17 and touch switch 9 transmitted by the security encryption chip 50. At this time, the slide switch 17 is in the initial state, indicating that it is not opened and released, and the touch switch 9 is in the non-initial state. Under these circumstances, the manufacturer's PC management platform and cloud encrypted database allow the appraiser to input the appraisal information data into the manufacturer's PC management platform and cloud encrypted database. After the appraiser inputs the appraisal information data, the appraisal data is solidified through real-name authentication and / or biometric identification and digital signature, and then uploaded to the manufacturer's PC management platform and cloud encrypted database. At this point, the appraisal information data cannot be changed.
[0081] S3. Anti-counterfeiting verification: The user forms an encrypted data link with the handheld communication device through the human-computer interaction interface, the product manufacturer's PC management platform, the cloud encrypted database, and the anti-counterfeiting device. The encrypted data queue that is finally uploaded to the authentication information data contains the ID of the security encryption chip 50 of the anti-counterfeiting device and the ID of the communication chip 49. The authentication information data is bound to the anti-counterfeiting device and the genuine product after authentication, forming a one-to-one correspondence.
[0082] The anti-counterfeiting verification user can power the PCB circuit board 43 through an external power interface or wireless power supply, or through an internal battery. After the PCB circuit board 43 is powered, the security encryption chip 50 checks the position and status of the slide switch 17 and the touch switch 9.
[0083] The security encryption chip 50 establishes an encrypted data link with the product manufacturer's PC management platform and cloud encryption database (public key, private key) through the communication chip 49 to perform asymmetric encryption and decryption mutual verification. Both parties confirm that the identities are valid and legitimate. If the communication chip 49 is a remote communication chip, the anti-counterfeiting device will directly link with the product manufacturer's PC management platform and cloud encryption database. If the communication chip 49 is a short-range communication chip, it will link with the handheld communication device of the anti-counterfeiting verification user through the human-computer interaction interface and then link with the product manufacturer's PC management platform and cloud encryption database.
[0084] The anti-counterfeiting verification user sends a verification request to the product manufacturer's PC management platform and cloud encrypted database through a handheld communication device with a human-computer interaction interface. The product manufacturer's PC management platform and cloud encrypted database issue an asymmetric encrypted dynamic code. After the security encryption chip 50 on the anti-counterfeiting device's PCB circuit board 43 decrypts the code, it is displayed on the display screen 45. The anti-counterfeiting verification user also displays the code simultaneously through the handheld communication device with the human-computer interaction interface. The anti-counterfeiting verification user determines whether the product is genuine, legal and valid by comparing whether the dynamic code displayed on the handheld communication device with the dynamic code displayed on the anti-counterfeiting device's display screen 45 is consistent.
[0085] Because the genuine product 64 is protected by the anti-counterfeiting device after authentication, the validity and uniqueness of the authentication information are always maintained before the anti-counterfeiting device is opened and released. In subsequent multiple transactions, the anti-counterfeiting verification user only needs to power the anti-counterfeiting device, so that the anti-counterfeiting verification user's human-computer interaction interface handheld communication device, the product manufacturer's PC management platform and cloud encrypted database, and the anti-counterfeiting device form an encrypted data link network. The anti-counterfeiting verification user obtains the encrypted authentication information data issued by the product manufacturer's PC management platform and cloud encrypted database, without the need for multiple additional authentications.
[0086] S4. The anti-counterfeiting verification user sends an opening and release request to the product manufacturer's PC management platform and cloud encrypted database through the human-computer interaction interface and handheld communication device. The product manufacturer's PC management platform and cloud encrypted database issue an asymmetric encryption opening and release command. After receiving the asymmetric encryption command through the communication chip 49, the security encryption chip 50 on the anti-counterfeiting device PCB circuit board 43 performs encryption and decryption authentication. After confirming that it is legal and valid, the security encryption chip 50 on the PCB circuit board 43 controls the power control circuit to supply power to the heating element 47. The heating element 47 heats up and melts the low-temperature fusible metal column 19, the swing arm 18 is released from restriction, the unlocking motion spring 14 pushes the sleeve 1 to move backward, the sleeve 1 drives the sliding switch 17 to move. At this time, the disposable snap 2 is also driven to move backward through the lower limit block 16 of the disposable snap 2. Thus, the disposable snap 2 and the snap 2 limit sliding block 3 are separated from the limit structure 13 on the outer shell 12. The outer shell 12 can then be removed from the differential limit structure 26, and the anti-counterfeiting verification user obtains the protected product 64.
[0087] The anti-counterfeiting verification user can also use an external heat source to heat the low-temperature fusible metal fixing rivet 22 on the back of the base 24. The low-temperature fusible metal fixing rivet 22 conducts heat to the low-temperature fusible metal column 19 through the low-temperature fusible metal fixing ring 21, melting the low-temperature fusible metal column 19, thereby obtaining the protected product 64.
[0088] The security encryption chip 50 automatically detects the position of the sliding switch 17. At this time, the sliding switch 17 is in a non-initial state. The sliding switch 17 sends a signal to the security encryption chip 50. The security encryption chip 50 sends a signal to the product manufacturer's PC management platform and cloud encryption database through the communication chip 49, indicating that the anti-counterfeiting device has been activated and released. The product manufacturer's PC management platform and cloud encryption database automatically close the data queue of the anti-counterfeiting device. The anti-counterfeiting device automatically executes the self-destruct program of the security encryption chip 50.
