Description

Technical Field

[0001] This application relates to the field of atomization equipment technology, specifically to an anti-tamper detection device and an aerosol generation device. Background Technology

[0002] Aerosol generating devices are devices that atomize an aerosol generating matrix into inhalable aerosols through electronic heating. Their core structure typically includes a battery module, heating components, control circuitry, and an aerosol generating chamber. Some smart devices also integrate sensors, displays, and wireless communication modules to achieve power regulation, usage data recording, and interaction with mobile terminals. They are considered to have relatively low health risks, but issues such as device security, data privacy protection, and intellectual property infringement are becoming increasingly prominent.

[0003] With technological advancements in the industry, product development has shifted from simple hardware optimization to deep integration of hardware and software. For example, embedded software enables precise temperature control, user behavior analysis, and data exchange with health management apps. These innovations not only enhance user experience but also transform devices into storage containers for sensitive data. Previously, the focus for protecting sensitive data carried and processed by devices was primarily on layers of encryption, neglecting the physical protection of the device itself. For professional data thieves, simply disassembling the device and using specialized techniques allows them to obtain or steal information stored within, reverse-engineer it to uncover technical secrets, and even user privacy data. This issue deserves serious attention.

[0004] Therefore, based on software security protection, it is essential to design active anti-disassembly technology to build physical structure protection, block competitors from obtaining technical data through physical means, protect user data, and maintain product security and market competitiveness.

The embodiments of this application will now be described with reference to the accompanying drawings.

[0036] Figure 1 This is a schematic diagram of the structure of an aerosol generation device provided in one embodiment of this application. Figure 1As shown, the aerosol generating device provided in this embodiment includes a housing 110 and a power supply module 120, an atomizer 130, a controller 140 and an anti-tamper detection device 150 encapsulated within the housing 110.

[0037] In this embodiment, the housing 110 is the external structural component of the aerosol generating device, serving as the support and protective frame for the entire device. The housing 110 is typically formed by joining multiple housing units together, with its inner walls enclosing a closed or semi-closed receiving cavity. This receiving cavity is used to house and fix various functional modules of the device, providing not only physical positioning and protection but also isolating them from the external environment, preventing dust and moisture, and resisting mechanical impact.

[0038] The power supply module 120 can provide stable power for the operation of the atomizer 130 heating, the controller 140 calculation, and some of the sensors, display modules and interactive communication modules contained in the device, through a precision power management chip to realize voltage conversion and regulated output for the rechargeable lithium-ion battery pack.

[0039] The atomizer 130 is the core component for realizing the aerosol generation function, mainly consisting of two parts: the aerosol generation matrix and the heating element. The heating element can be a metal resistance coil, a thick-film heating element, or a ceramic heating element. Driven by the controller 140, the heating element rapidly rises to the set temperature, uniformly and efficiently heating the aerosol generation matrix to volatilize into inhalable aerosols, while avoiding local overheating or degradation, thus ensuring consistent taste and safety of use.

[0040] The controller 140, as the "brain" of the aerosol generation device, is based on a microprocessor and is responsible for coordinating the operation of the entire device, including battery management, heating control, temperature regulation, user operation response and status indication. It achieves precise control of the atomization process through built-in dedicated algorithms and software programs, ensuring the stability and safety of the output aerosol. It can also integrate software protection mechanisms such as data encryption and device authentication.

[0041] Unlike traditional aerosol generation equipment, the aerosol generation equipment provided in this embodiment also includes an anti-tamper detection device 150, which is a security mechanism specifically designed to detect unauthorized disassembly. This device includes sensors and detection circuits. The device is installed at a critical assembly location of the housing 110. It generates electrical signals by monitoring the encapsulation status of the housing 110. Once an unexpected opening of the housing 110 or displacement of the internal structure is detected, a protection mechanism is triggered. After the protection mechanism is triggered, the aerosol generation equipment is permanently locked, critical data is cleared, or power is cut off through hardware and / or software, thereby preventing reverse engineering and software theft at the hardware level.

[0042] The tamper detection device 150, which is unique in this application, will be described in detail below.

[0043] Figure 2 This is a schematic diagram of the anti-tamper detection device provided in one embodiment of this application. Figure 2 As shown, the tamper detection device 150 provided in this embodiment is specifically disposed on the circuit board inside the aerosol generating device and connected to the controller 140. It can send a signal to the controller 140 when it detects a change in the assembly state of the housing 110 and / or the internal controller 140. Specifically, the tamper detection device 150 provided in this embodiment includes a detection module 210 and a monitoring module 220.

[0044] In this embodiment, the detection module 210 is directly or indirectly connected to the inner wall of the housing 110 of the aerosol generating device, the outer shell of the controller 140, or the fixing structure of both via physical / electrical connection or non-contact sensing. It forms a linkage with the housing 110 and the controller 140, continuously monitoring their assembly status, and serves as the signal sensing unit of the tamper detection device 150. In some embodiments, the detection module 210 incorporates high-precision sensors, such as microswitches, magnetic elements, pressure sensors, or conductive contacts, to monitor the assembly status of the housing 110 in real time, including its closed state, screw tightness, and subtle changes such as unauthorized displacement of the controller 140 or disconnection of critical connectors. When the device is in a normal encapsulation state, that is, the device has not been disassembled and the assembly state remains intact, the detection module 210 outputs a stable normal signal, such as a continuous low level or a signal with a specific code; once it detects that the housing 110 has been opened, the screws have been moved, or the controller 140 has been illegally moved, the detection module 210 will immediately switch to output a disassembly protection signal, such as a high level or an alarm code signal that is opposite to the normal signal, to provide a trigger basis for subsequent data protection actions and block the path of obtaining data or tampering with hardware through physical disassembly.

[0045] The monitoring module 220 is the logic processing and response unit of the tamper detection device 150. Its signal input terminal is connected to the detection module 210, and it is used to receive and analyze the signals output by the detection module 210 in real time. The monitoring module 220 has a built-in microprocessor chip with a simple algorithm, which can accurately distinguish between normal signals and tamper protection signals. When a normal signal is received, the monitoring module 220 remains silent to ensure the normal operation of the device. When a tamper protection signal is received, the monitoring module 220 immediately generates and outputs an erase protection signal. The erase protection signal is transmitted to the main controller 140 of the device through an electrical link. The erase protection signal is used to instruct the controller 140 to start an emergency security erase procedure to perform irreversible erase or lock operations on sensitive information such as key user data, device unique identifiers, heating control algorithms, core firmware programs, or user privacy data stored in the memory.

[0046] In summary, the anti-tamper detection device provided in this embodiment uses a detection module to sense changes in the physical state of key components of the device in real time. Upon detecting unauthorized disassembly, the monitoring module quickly triggers a data erasure protection mechanism. The collaborative work of the detection and monitoring modules achieves dual reinforcement of the physical and data security of electronic devices. This detection device adopts a hardware-level protection design, operating independently without relying on software encryption. It effectively blocks software reverse engineering and core data theft through hardware disassembly. The data erasure mechanism ensures that sensitive information stored on the device is completely erased instantly upon unauthorized disassembly, eliminating the risk of data leakage at the source and strengthening the overall security and market competitiveness of the product. Simultaneously, its modular structure can flexibly adapt to different models of electronic devices, balancing security and cost-effectiveness, providing an efficient and feasible anti-tampering and data protection solution for consumer electronics, smart hardware, and other fields.

[0047] In some embodiments, the sensing and detection mechanism in the detection module 210 can be a photosensitive sensor. The photosensitive sensor is disposed inside the housing 110 and is used to sense and detect the light inside the housing 110. When no change in the light inside the housing 110 is detected, a normal signal is output. When an increase in the light inside the housing 110 is detected, a disassembly protection signal is output.

[0048] Specifically, the photosensitive sensor is typically fixed in a non-directly lit location, such as on the inner wall of the housing 110, inside screw holes, in structural gaps, or on the main control board. It detects light intensity inside the housing 110 based on ambient light sensing. When the device is in a normal sealed state, the interior of the housing 110 is either dark or in a stable low-light environment, and the photosensitive sensor continuously outputs a normal signal. However, if the device is illegally disassembled, causing the housing 110 to open or develop cracks, external light enters the cavity. The sensor detects a significant increase in light intensity, thus identifying abnormal disassembly and immediately switching to a disassembly protection signal. Detection using a photosensitive sensor offers rapid response and concealed structure, making it particularly suitable for detecting whether the housing 110 has been illegally opened, and difficult to directly identify or circumvent from the outside.

[0049] In some embodiments, the sensing and detection mechanism in the detection module 210 can also be a pressure sensor. The sensing end of the pressure sensor is connected to the connection point on the housing 110 and / or the connection point between the controller 140 and the circuit board. The pressure sensor is used to detect the pressure signal at the connection point on the housing 110 and / or the connection point between the controller 140 and the circuit board. When the pressure at the connection point does not change, it outputs a normal signal. When the pressure at the connection point increases or decreases, it outputs a disassembly protection signal.

[0050] Specifically, a pressure-sensitive sensor is a sensing mechanism for physical connections. Its sensing end is typically tightly fitted to the seams of the housing 110, screw mounting points, or connectors or fixing points between the controller 140 and the circuit board. The pressure-sensitive sensor determines the state by sensing changes in pressure at these key mechanical connection points. Under normal assembly conditions, the pressure-sensitive sensor continuously senses the preset clamping force at the connection point and outputs a normal signal. However, when the housing 110 is disassembled or the controller 140 is illegally moved, the clamping force at the connection point disappears or undergoes abnormal changes, such as a decrease in pressure due to loose screws or a sudden increase in pressure caused by violent disassembly. Upon detecting this pressure change, the sensor determines that the connection structure is damaged and generates a disassembly protection signal. The pressure-sensitive sensor quantifies changes in physical connection strength and can sensitively capture minute mechanical deformations and assembly interferences. It is particularly suitable for modular equipment requiring disassembly and maintenance, ensuring both safety and ease of maintenance.

[0051] In some embodiments, the sensing and detection mechanism in the detection module 210 can also be a conductive contact. Multiple conductive contacts are connected in series through multiple leads to form a series circuit. The multiple conductive contacts are respectively arranged inside the housing 110 and / or on the controller 140. The conductive contacts are used to detect the resistance value in contact with the housing 110 and / or the controller 140, and the resistance value is used as the detection signal. When no change in the resistance value is detected, a normal signal is output. When an increase in the resistance value is detected, a disassembly protection signal is output.

[0052] Specifically, multiple conductive contacts are precisely arranged at key joints on the inner surface of the housing 110 (such as around screw holes or snap-fit ​​contact surfaces) or on the surface of the controller 140. These contacts are connected in series with multiple low-resistance leads according to a preset topology to form a closed detection loop. Monitoring is achieved based on the stability of the loop resistance. Under normal encapsulation conditions, each conductive contact maintains a stable physical connection with its corresponding contact surface, and the loop resistance value remains constant and within a preset threshold range. At this time, the detection module 210 outputs a normal signal. However, when the housing 110 is pried open, screws are loosened, or the controller 140 is illegally displaced, the pressure distribution or contact area between the conductive contacts and the contact surface changes, causing significant fluctuations in the loop resistance value. For example, poor contact may cause a sudden increase in resistance, or a short circuit may cause the resistance to approach zero, resulting in a sudden change in loop resistance. The detection module 210 immediately outputs a disassembly protection signal by real-time acquisition of resistance value changes and triggering a threshold comparison algorithm. This detection method uses the overall circuit continuity or resistance change as the criterion. By quantifying the changes in physical connection status, it has the advantages of high sensitivity and resistance to environmental interference. It is also simple in structure and reliable in response. It can effectively monitor the damage to distributed structures. Furthermore, because the contact points are concealed and the wiring is complex, it is difficult to be easily identified or bypassed by the outside, which can improve the robustness and anti-circumvention capabilities of the anti-tampering device.

[0053] In some embodiments, the sensing and detection mechanism in the detection module 210 can also be an environmental sensor. The environmental sensor is disposed inside the housing 110 and generally serves as a supplement to the previous centralized detection method. The environmental sensor is used to sense and detect environmental parameters inside the housing 110. When no change is detected in the environmental parameters, it outputs a normal signal; when a change is detected in the environmental parameters, it outputs a disassembly protection signal. The environmental parameters include at least one of ambient temperature and humidity, oxygen concentration, and pressure.

[0054] Specifically, environmental sensors, as an effective supplement to the aforementioned detection methods, are based on the dynamic monitoring of micro-environmental parameters within the housing 110. They are typically integrated into sealed cavities within the equipment or near key components, continuously monitoring micro-environmental parameters such as ambient temperature, humidity, oxygen concentration, or pressure to establish a baseline data model under normal operating conditions. When the equipment is not disassembled and remains sealed, the housing 110 forms a physical isolation barrier, maintaining relatively stable internal environmental parameters, and the sensor outputs a normal signal accordingly. However, when the housing 110 is illegally pried open or drilled, external air enters the cavity, causing changes in internal temperature, humidity, air pressure, or gas concentration, such as a sudden increase in oxygen concentration or abnormal pressure fluctuations due to seal failure. The environmental sensor detects these changes by capturing the trend of parameters deviating from the baseline threshold, determining the physical intrusion behavior, and outputting a disassembly protection signal. This detection method does not rely on physical contact and can effectively counter non-destructive disassembly or evasion tactics against other sensing methods. By constructing a protective layer through the invisible monitoring of environmental parameters, it further enhances the robustness and adaptability of the anti-tamper device in complex scenarios.

[0055] It should be noted that the aforementioned detection methods, including photosensitive sensors, pressure-sensitive sensors, conductive contacts, and environmental sensors, can be flexibly selected, combined, and used in practice according to the specific anti-tampering requirements, structural space, cost control, and security level requirements of different products. For example, in consumer electronics fields such as aerosol generation equipment, photosensitive sensors can be used alone to achieve low-cost basic protection. For high-security scenarios such as industrial control equipment, pressure-sensitive sensors and conductive contacts can be superimposed to form a dual physical detection mechanism. If it is necessary to deal with covert tampering attacks, temperature, humidity, or oxygen concentration sensors can be added as supplements. When designing the anti-tampering detection device 150, different types of detection mechanisms can be deployed at multiple key locations in the equipment to build a multi-layered, cross-verified sensing network. This significantly improves the overall coverage, robustness, and anti-evasion capabilities of the anti-tampering system in complex application scenarios, achieving more comprehensive and adaptive protection against physical intrusion.

[0056] In addition, the aforementioned anti-tamper detection device 150 is not only applicable to aerosol generation equipment, but can also be widely integrated into smartphones, smart wearable devices, medical electronic instruments, industrial control systems and other high-value consumer electronics products to protect their internal hardware and software designs and critical data. By monitoring the opening and closing status of the device housing 110 or the displacement of the internal structure in real time, and triggering data erasure or function lock-up mechanisms when illegal disassembly is detected, it can effectively deal with physical reverse engineering and sensitive information theft behaviors targeting various electronic products, and provide a universal hardware-level security protection solution for electronic devices in multiple industries.

[0057] Figure 3 This is a schematic diagram of the anti-tamper detection device provided in another embodiment of this application. Figure 3 As shown, the tamper detection device 150 provided in this embodiment, based on any of the above embodiments, also includes a detection circuit 230.

[0058] In this embodiment, the detection circuit 230 includes a voltage divider unit 2301; the first end of the voltage divider unit 2301 is connected to an external input power supply, the second end of the voltage divider unit 2301 is connected to the output end of the detection module 210, and the third end of the voltage divider unit 2301 is connected to the input end of the monitoring module 220; the voltage divider unit 2301 is used to convert the physical quantity detected by the detection module 210 into a voltage signal and output it to the monitoring module 220.

[0059] The detection circuit 230, as a supplement to the detection module 210, is used to improve the accuracy and reliability of signal processing. Specifically, the detection circuit 230 includes a voltage divider unit 2301, the first terminal of which is connected to an external input power supply to obtain a reference voltage, the second terminal of which is connected to the output terminal of the detection module 210 to receive the raw sensing signal, and the third terminal of which is connected to the input terminal of the monitoring module 220. A resistor voltage divider network or bridge circuit structure is used, typically employing resistors to achieve voltage division. Through resistor voltage division, the physical quantities (such as light intensity, pressure, or resistance changes) output by the detection module 210 (e.g., photosensors, pressure sensors, and conductive contacts) are converted into standard voltage signals. When the detection module 210 senses the disassembly of the housing 110 or the displacement of the controller 140, its output impedance or electrical signal characteristics change. The voltage divider unit 2301 dynamically adjusts the three-terminal voltage distribution ratio to convert the physical quantity change into a linear voltage signal, which is then transmitted to the monitoring module 220. This enables the standardization and adaptation of weak or nonlinear signals, allowing the monitoring module 220 to accurately identify changes in physical state and trigger corresponding protection actions, thereby achieving signal isolation and enhanced anti-interference.

[0060] In some embodiments, the detection circuit 230 further includes a filtering unit 2302. One end of the filtering unit 2302 is connected to the first end of the voltage divider unit 2301, and the other end is grounded to form an energy discharge path. This filtering unit is used to filter out high-frequency noise, transient pulses, or environmental electromagnetic interference in the input power supply, thereby providing a stable and clean reference voltage for the voltage divider unit 2301 and the subsequent detection circuit 230. This unit typically employs a low-pass filter structure composed of capacitors, inductors, RC filter networks, or ferrite beads. High-frequency interference components are bypassed to ground through capacitors or blocked from propagation through inductors, allowing only low-frequency effective signals related to tamper detection to be transmitted to subsequent circuits through the voltage divider unit 2301. This effectively suppresses signal anomalies caused by power fluctuations or external interference, avoids false triggering of the voltage divider unit 2301, and thus improves the accuracy and anti-interference capability of the tamper detection device 150 in detecting physical quantities, ensuring the reliability of tamper judgment.

[0061] Figure 4 This is a schematic diagram of the anti-tamper detection device provided in another embodiment of this application. Figure 4 As shown, the tamper detection device 150 provided in this embodiment further includes a threshold configuration module 240 based on any of the above embodiments.

[0062] In this embodiment, the threshold configuration module 240 is used to provide a detection threshold to the monitoring module 220; the monitoring module 220 is used to output an erase protection signal for instructing the controller 140 of the electronic device to erase different data ranges based on the relationship between the detection threshold and the voltage value of the disassembly protection signal.

[0063] Specifically, the threshold configuration module 240 presets or dynamically sets one or a set of suitable detection thresholds, such as the light intensity threshold for a photosensitive sensor and the pressure change threshold for a pressure-sensitive sensor, through hardware DIP switches, programmable resistor networks, or software registers, and provides these thresholds to the monitoring module 220. When the detection module 210 outputs a tamper protection signal, the monitoring module 220 compares the actual voltage value of the received tamper protection signal with the currently effective preset threshold. Based on the magnitude or duration of exceeding the threshold, it outputs different levels of erase protection signals, thereby instructing the controller 140 to perform differentiated data erase operations. For example, if the signal strength is below the primary threshold (i.e., a minor anomaly occurs), only the operation log is erased; if the signal strength exceeds the intermediate threshold (i.e., a moderate anomaly occurs), the device key and firmware algorithm are simultaneously erased; if the signal strength reaches the highest threshold (i.e., a severe anomaly occurs), the core algorithm and user privacy data are erased, and a hardware-level self-destruct program is executed. This tiered threshold mechanism achieves precise control over tiered security responses and data protection scope, significantly improving the system's adaptability to different risk scenarios and the level of protection refinement.

[0064] In some embodiments, the threshold configuration module 240 includes an adjustable potentiometer; the first terminal of the adjustable potentiometer is connected to an external input power supply, the second terminal of the adjustable potentiometer is grounded, and the adjustment terminal of the adjustable potentiometer is used to output the detection threshold.

[0065] The adjustable potentiometer uses a three-terminal structure (input terminal connected to an external stable power supply, output terminal grounded, and adjustment terminal outputting a variable voltage) to form a voltage divider network. Users can continuously change the resistance ratio between the adjustment terminal and ground by rotating the knob or sliding the contact, thereby outputting a linearly adjustable voltage signal from 0V to the power supply voltage as a detection threshold. The adjustable potentiometer has a simple structure and is suitable for various devices and environments.

[0066] It should be noted that the threshold configuration module 240 can be designed as a standalone external module (e.g., manually set via an adjustable potentiometer) or integrated as a built-in function into the chip or firmware of the monitoring module 220. The external form allows for flexible on-site threshold adjustment to adapt to different sensors or environmental requirements, while the integrated form enables dynamic threshold adjustment through software configuration. This helps reduce external components, improve system integration and automation levels, and allows for selection of the optimal configuration based on actual application needs, considering cost control, debugging flexibility, and intelligent response.

[0067] Figure 5 This is a schematic diagram of the anti-tamper detection device provided in another embodiment of this application. Figure 5 As shown, in some embodiments, when the voltage signal output by the detection module 210 is an analog voltage signal, the detection circuit 230 further includes an ADC unit 2303 connected between the voltage divider unit 2301 and the monitoring module 220; the ADC unit 2303 is used to convert the analog voltage signal into a digital signal and transmit it to the monitoring module 220; the threshold configuration module 240 is connected to the ADC unit 2303 and is used to output a detection threshold to the monitoring module 220 through the ADC unit 2303.

[0068] In the adaptability design of the tamper detection device 150, the detection circuit 230 adopts a dynamic signal adaptation strategy to address the differences in signal input types of the monitoring module 220. When the monitoring module 220 supports analog signal input, the detection circuit 230 directly transmits the analog voltage signal output by the sensor to the monitoring module 220 after linear scaling through the voltage divider unit 2301, ensuring that the signal amplitude matches its input range. For the monitoring module 220 that only receives digital signals, a high-precision ADC unit 2303 is added to convert the analog signal output by the voltage divider unit 2301 into a digital code of a specific resolution at a preset sampling frequency. At the same time, the threshold configuration module 240 writes a reference threshold to the ADC through the digital bus, enabling the monitoring module 220 to directly compare the digital signal with the threshold, thereby triggering the corresponding security response and improving the versatility of the detection device.

[0069] For the analog voltage signal output by the detection module 210, the ADC unit 2303 serves as an analog-to-digital signal conversion interface. Its input is connected to the voltage signal output of the voltage divider unit 2301, and its output is connected to the monitoring module 220. This unit converts the analog voltage signal after voltage division and conditioning by the detection module 210 into a digital quantity, so that the monitoring module 220 can perform accurate digital comparison and processing. At the same time, the threshold configuration module 240 can also be interconnected with the ADC unit 2303. Through a digital communication interface or a hybrid analog-digital method, it transmits the detection threshold (such as the voltage value corresponding to the light intensity threshold or pressure threshold) to the monitoring module 220 in the form of a digital signal. The monitoring module 220 accurately determines whether to trigger data erasure protection by reading the comparison result of the ADC conversion result and the digital value of the threshold, thereby realizing dynamic threshold configuration and adaptive judgment based on the digital domain.

[0070] Figure 6 This is a schematic diagram of the anti-tamper detection device provided in another embodiment of this application. Figure 6 As shown, the tamper detection device 150 provided in this embodiment further includes an alarm module 250 based on any of the above embodiments.

[0071] In this embodiment, the alarm module 250 is connected to the monitoring module 220; the monitoring module 220 is also used to output an alarm trigger signal to the alarm module 250 according to the disassembly protection signal and the detection threshold; wherein, when the sampled value of the disassembly protection signal is greater than or equal to the detection threshold, the alarm trigger signal is used to instruct the alarm module 250 to issue a high-level alarm message, and when the sampled value of the disassembly protection signal is less than the detection threshold, the alarm trigger signal is used to instruct the alarm module 250 to issue a low-level alarm message.

[0072] In this embodiment, a hierarchical security protection system is formed in the anti-tamper detection device 150 through the alarm module 250. The alarm module 250 serves as a response and warning unit, with its input end connected to the monitoring module 220 to receive the alarm trigger signal output by the monitoring module 220, and its output end connected to the alarm components. The alarm components may include acoustic alarms (such as buzzers or speakers), optical indicators (such as LED indicators or flashing lights), tactile feedback devices (such as vibration motors), and communication transmission modules (such as Wi-Fi / Bluetooth transmitters). Acoustic and optical components can directly provide local high-decibel sound or conspicuous visual cues, vibration modules are suitable for concealed scenarios, and communication modules can realize remote real-time alarms. These components can be used individually or in combination to form a multi-level, internally and externally coordinated alarm response system to meet the needs of different scenarios for alarm intensity, form, and propagation range.

[0073] The monitoring module 220 compares the real-time sampled value of the disassembly protection signal output by the detection module 210 with a preset detection threshold, and generates differentiated alarm trigger signals based on the difference. Specifically, when the sampled value of the disassembly protection signal is greater than or equal to the threshold, it indicates a high-risk disassembly, and the monitoring module 220 outputs a trigger signal to cause the alarm module 250 to issue a high-level alarm message (such as continuous beeping, rapid flashing of lights, or remote alarm); when the sampled value is less than the threshold but an anomaly exists, it may be a minor interference or attempted disassembly, and a low-level alarm message (such as intermittent prompts or slow flashing of local indicator lights) is triggered. This hierarchical response mechanism can achieve differentiated warnings for threats of different degrees and avoid false alarms; while ensuring data security, it also provides users or maintenance personnel with clear status identification and operation guidance, further improving the overall protection effectiveness and human-machine interaction experience.

[0074] Figure 7 This is a circuit diagram of an anti-tamper detection device provided in one embodiment of this application. Figure 7 As shown, the tamper detection device 150 provided in this embodiment includes a detection module 210, a detection circuit 230, a monitoring module 220, and a threshold configuration module 240. The detection module 210 uses a photoresistor RG1 (RG5506) as its core to sense changes in illumination inside the housing 110. The detection circuit 230 includes a voltage divider unit 2301 composed of resistors R1 and R2, and a filter unit 2302 composed of multiple capacitors (C1-C3), responsible for stabilizing and standardizing the original light-sensing signal. The monitoring module 220 uses a microcontroller U4 (STM32F103 series chip) as its core for signal acquisition and logic judgment. The threshold configuration module 240 is implemented through an adjustable potentiometer R4 and a resistor R3, allowing flexible adjustment of the sensitivity of the trigger protection. In this embodiment, the alarm module 250 is not shown in detail in the circuit diagram, but as described above, it can be connected to the monitoring module 220 for alarm purposes.

[0075] The working process of the tamper detection device 150 provided in this embodiment is as follows:

[0076] As the core component of the detection module 210, the photoresistor RG1 has a resistance that changes with the light intensity. The analog voltage signal corresponding to the voltage change at the photoresistor is divided and filtered, and then connected to the PA5 and PA4 pins of the ADC unit P11 via jumpers. The ADC unit P11 converts the analog voltage signal into a digital signal and transmits it to the monitoring module U4. The threshold configuration module 240 sets a detection threshold voltage through the adjustable potentiometer R4. The monitoring module U4 compares the voltage value represented by the received digital signal with the detection threshold set by the threshold configuration module 240.

[0077] When the aerosol generating equipment is in normal, undisassembled condition, the illumination inside the housing 110 is stable, the resistance of the photoresistor is relatively fixed and high, and the voltage signal received by the monitoring module U4 is high, close to the input voltage. When the housing 110 is illegally opened, ambient light enters, causing the resistance of the photoresistor to drop. At this time, the voltage signal received by the monitoring module U4 will drop sharply. Thus, the monitoring module U4 can determine the disassembly behavior and trigger data erasure and / or alarm response.

[0078] In summary, the tamper detection device for electronic devices such as aerosol generation equipment provided in any of the above embodiments monitors changes in device status in real time through multi-physical quantity sensing mechanisms (such as photosensitive, pressure-sensitive, conductive contacts, and environmental sensors). By means of signal conditioning, threshold comparison, and graded response mechanisms, it can quickly trigger data erasure, function locking, and timely graded warnings when illegal disassembly is detected. This effectively resists reverse engineering and data theft at the hardware level, protects core intellectual property rights and user privacy, and significantly enhances the product's technical barriers and market competitiveness. At the same time, its modular design supports flexible adaptation to various electronic devices and has high reliability and environmental adaptability.
