[0002] The aerosol generating device uses a heating without burning mechanism to achieve matrix atomization. The residual gas after heating gradually cools down into attachments and deposits to the bottom of the cleaning box. During the plugging and unplugging process of some aerosol matrices, a small amount of residual material will fall to the bottom of the cleaning box. If the cleaning box is not cleaned for a long time, it will seriously affect the user's atomization experience and the service life of the equipment.

[0003] At present, some aerosol generating devices are provided with a cleaning brush or cleaning cotton when leaving the factory, and users are advised to clean them regularly.

[0056] First, some terms in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.

[0057] An aerosol generating device is an electronic product that generates steam and releases aerosol by heating an aerosol matrix or heating a non-combustible low-temperature aerosol matrix. This is different from traditional products that release aerosol through combustion.

[0058] The above is a brief introduction to the nouns involved in the embodiments of the present application, which will not be repeated below.

[0059] This application example provides an example of an aerosol generating device, please refer to Figure 1 As shown, Figure 1 The schematic structural diagram of an aerosol generating device provided by the present application is shown. The aerosol generating device 100 comprises:

[0060] The aerosol generating unit 101 is disposed inside the aerosol generating device 100 and is used for placing an aerosol matrix and generating an aerosol by heating the aerosol matrix.

[0061] The residual substance storage unit 102 is disposed below the aerosol generating unit 101 and connected to the aerosol generating unit 101 to receive and contain the residual substance of the aerosol generating unit.

[0062] The infrared sensor 103 is disposed at a predetermined height position of the residual material storage unit 102 and is used to detect the residual material in the residual material storage unit and obtain a corresponding infrared sampling value.

[0063] The controller 104 is connected to the infrared sensor 103 and is used to feed back cleaning prompt information according to the infrared sampling value, wherein the cleaning prompt information is used to instruct to clean the residual material storage unit.

[0064] Optionally, in the example of the present application, the aerosol generating unit is used to place an aerosol matrix, for example, a mixture of herbs such as mint, licorice, cloves, chrysanthemum, etc., and heat the aerosol matrix through a built-in heating component to atomize the substance in the aerosol matrix without burning, thereby forming an aerosol that can be used by users.

[0065] Optionally, in one example, the heating mechanism adopted by the aerosol generating unit may be a heat not burn (HNB) technology, which can release the odor components of the aerosol matrix at a lower temperature while reducing the harmful substances produced by traditional combustion methods.

[0066] Optionally, the residual material storage unit is disposed below the aerosol generating unit and is connected to the aerosol generating unit. During the operation of the aerosol generating unit, the residual gas after heating gradually cools down to become attachments, and adheres to the inner wall of the aerosol generating unit, and then deposits to the bottom of the aerosol generating unit; during the plugging and unplugging process of some aerosol matrices, a small amount of residual material will fall to the bottom of the aerosol generating unit. By providing a diversion channel at the bottom of the aerosol generating unit, etc., the residual material remaining at the bottom of the aerosol generating unit is collected in the residual material storage unit (i.e., a cleaning box, a cleaning cup), so that the residual material storage unit can receive and contain these residual materials.

[0067] Optionally, in the example of the present application, the infrared sensor is installed at a predetermined height position of the residual material storage unit. The predetermined height position can be set based on the comprehensive requirements of the residual material accumulation and the equipment cleaning requirements, and can be specifically determined based on the maximum allowable accumulation height of the residual material in the residual material storage unit. For example, when the residual material accumulates to a certain height and affects the equipment performance, the position corresponding to the height is the installation position of the infrared sensor. Figure 1 As shown, when the infrared sensor is working, it continuously emits infrared light in the horizontal direction as indicated by the dotted line, and receives the reflected infrared light.

[0068] In this application example, the controller is connected to the infrared sensor, and the controller pre-stores judgment logic and threshold data obtained based on experiments and actual tests. After receiving the infrared sampling value sent by the infrared sensor, the controller analyzes and judges the infrared sampling value according to the preset judgment logic and threshold data, and then determines whether to feedback the cleaning prompt information.

[0069] When the infrared light emitted by the infrared sensor encounters the residual material in the residual material storage unit, it is reflected, scattered, and other phenomena occur. When there is less residual material, most of the infrared light can smoothly reach the shell position of the residual material storage unit farther away and reflect back to the infrared sensor. At this time, the intensity of the infrared light received by the infrared sensor is higher, and the corresponding infrared sampling value is also larger. As the residual material continues to accumulate, when the residual material in the residual material storage unit reaches or exceeds the predetermined height, more infrared light is absorbed or scattered by the residual material, and the intensity of the infrared light returned to the sensor is weakened, resulting in a decrease in the infrared sampling value.

[0070] In an optional embodiment, after the controller receives the infrared sampling value sent by the infrared sensor, it compares the infrared sampling value with a preset sampling threshold. The sampling threshold is determined based on a large number of experiments and actual usage experience, and indicates the critical value of the infrared sampling value corresponding to when the residual material reaches the level that needs to be cleaned.

[0071] If the infrared sampling value is less than or equal to the sampling threshold, it indicates that the residual material has accumulated to the extent that it needs to be cleaned, and the controller will trigger the feedback mechanism of the cleaning prompt information. Optionally, the cleaning prompt information can be presented to the user in a variety of ways, for example, by displaying a text prompt of "Please clean the cleaning box" on the display screen; or by controlling the indicator light on the device to flash, such as the red indicator light flashing at a specific frequency; or by using the voice module to play a voice prompt of "Too much residual material, please clean" to remind the user to clean the residual material storage unit.

[0072] This application scheme uses the cooperation of infrared sensors and controllers to realize the intelligent monitoring and prompting of the residual material storage unit cleaning by the aerosol generating device. There is no need for the user to manually check or judge. The device automatically senses the residual material situation and gives prompts, which improves the intelligence of the device and the convenience of user use. The infrared sensor detects the accumulation height of the residual material in real time, converts it into an infrared sampling value and transmits it to the controller; the controller determines the amount of residual material based on the infrared sampling value, and then, when the infrared sampling value reaches the sampling threshold for prompting cleaning, the controller promptly feedbacks the cleaning prompt information. The user does not need to rely on experience or guesswork to clearly know the degree of contamination in the residual material storage unit. The user can accurately grasp the cleaning time, avoid excessive cleaning or untimely cleaning, improve cleaning efficiency, and solve the problems of low cleaning efficiency and insufficient cleaning health.

[0073] In a possible implementation, the infrared sensor includes:

[0074] An infrared emitting diode, used for emitting infrared light into the interior of the residual material storage unit;

[0075] An infrared receiving diode is used to receive infrared light emitted by the infrared emitting diode and reflected or scattered back by the residual material storage unit, and generate a photocurrent, wherein the magnitude of the photocurrent is proportional to the intensity of the infrared light received by the infrared receiving diode;

[0076] The signal processing circuit is connected to the infrared receiving diode and is used for converting the photocurrent into an analog electrical signal, and converting the analog electrical signal after amplification and filtering into a digital signal to obtain an infrared sampling value.

[0077] Optionally, the infrared emitting diode is the signal emission source of the infrared sensor, which works based on the electroluminescent effect of the semiconductor. When a forward voltage is applied to both ends, electrons and holes recombine in the semiconductor material, thereby releasing energy in the form of infrared light. In the aerosol generating device, the infrared emitting diode is precisely installed at a specific position above the residual material storage unit to ensure that the emitted infrared light can evenly cover the area to be monitored inside the residual material storage unit.

[0078] The infrared receiving diode works in conjunction with the infrared emitting diode to receive infrared light emitted by the infrared emitting diode and reflected or scattered back through the residual material storage unit. When the infrared light irradiates the photosensitive area of ​​the infrared receiving diode, the energy of the photon is absorbed, thereby exciting the generation of electron-hole pairs, which move in a directional manner under the action of the electric field inside the diode to form a photocurrent. The magnitude of the photocurrent is proportional to the intensity of the infrared light received by the infrared receiving diode. In the residual material storage unit, when there is less residual material, the intensity of the reflected or scattered infrared light is higher, and the photocurrent generated by the infrared receiving diode is larger; conversely, when the residual material increases, more infrared light is blocked or scattered, resulting in a decrease in the intensity of the returned infrared light, and the photocurrent also decreases accordingly.

[0079] The signal processing circuit converts the photocurrent generated by the infrared receiving diode into an analog electrical signal. Specifically, the preamplifier in the signal processing circuit can be used to preliminarily amplify the photocurrent and convert the photocurrent into an analog voltage signal with a certain amplitude. The size of the analog voltage signal is proportional to the size of the photocurrent, which indirectly reflects the intensity of the infrared light received by the infrared receiving diode.

[0080] After the analog electrical signal is obtained through preliminary conversion, an amplifier circuit can be used to further increase the amplitude of the analog signal and enhance the anti-interference ability of the analog signal. At the same time, the filter circuit removes high-frequency noise and low-frequency clutter in the signal according to the set frequency range, and only retains the useful frequency components related to the infrared light signal, making the analog signal purer and more stable.

[0081] The analog electrical signal after amplification and filtering needs to be converted into a digital signal so that the controller can process and analyze it. The analog-to-digital converter (ADC) in the signal processing circuit converts the amplitude of the analog signal into a digital value according to certain quantization rules, which is the final infrared sampling value. For example, a 12-bit ADC can quantize the amplitude of the analog signal into a digital value in the range of 0-4095, and a 16-bit ADC can quantize the amplitude of the analog signal into a digital value in the range of 0-65535. It should be understood that the conversion accuracy of the ADC determines the resolution of the infrared sampling value. A higher resolution can more accurately reflect the changes in the intensity of infrared light, thereby more accurately detecting the situation of residual substances in the residual substance storage unit. Finally, the obtained infrared sampling value is transmitted to the controller through the connecting line, providing data basis for the controller to determine whether the residual substance storage unit needs to be cleaned.

[0082] In a possible implementation, the controller is further configured to:

[0083] In response to receiving a user's instruction to start heating, detecting whether the aerosol generating device is in a locked state, wherein the instruction to start heating is generated by at least one of a key operation, a touch screen operation, and a distance detection operation.

[0084] If it is detected that the aerosol generating device is in a locked state, the start-up heating operation is prohibited and a status prompt information is fed back, wherein the status prompt information is used to indicate that the aerosol generating device is in a locked state.

[0085] If it is detected that the aerosol generating device is not in a locked state, a cleaning reminder message is fed back based on the infrared sampling value.

[0086] Optionally, in the example of the present application, the user can send a start heating instruction to the aerosol generating device through a variety of interactive methods, including key operation, touch screen operation and distance detection operation.

[0087] Optionally, in one example, the aerosol generating device is equipped with a physical button, and when the user presses the button, the circuit inside the button is closed, generating an electrical signal, which is transmitted along the connecting line to the controller, and the controller recognizes it as a command to start heating.

[0088] Optionally, in another example, the aerosol generating device is equipped with a touch screen, and the user performs specific touch operations on the screen, such as clicking a heating icon or executing a preset gesture. After the touch screen senses the touch action, it converts it into an electrical signal and transmits it to the controller as a command to start heating.

[0089] Optionally, in another example, a distance sensor, such as an infrared distance sensor or an ultrasonic distance sensor, is installed in the aerosol generating device. When it is detected that the user's hand or other object approaches a preset distance range, the distance sensor outputs a corresponding signal to the controller, and the signal is regarded as a heating start instruction.

[0090] In the example of the present application, after receiving the instruction to start heating, the controller immediately detects whether the aerosol generating device is in a locked state. The locked state may be triggered by a variety of reasons, such as the child lock function is turned on, the device is in a fault protection state, etc.

[0091] In one example, if the aerosol generating device uses a hardware locking method such as a mechanical lock or an electronic lock, for example, when the mechanical lock is in the locked position, a micro switch is triggered, and the electrical signal generated by the micro switch is read by the controller, thereby determining that the device is in a locked state. In another example, the aerosol generating device can set the lock state through software. The controller checks the internal status flag or a specific register value to determine whether the device is locked by software.

[0092] In this application example, if the controller detects that the device is in a locked state, in order to ensure safety and comply with the operating rules of the device, the start-up heating operation is prohibited. At the same time, the controller triggers a mechanism for feedback of status prompt information. The status prompt information can be presented to the user in a variety of ways, such as displaying a text prompt "The device is locked, please unlock before operation" on the device's display screen; or by flashing an indicator light, such as a red indicator light flashing quickly to indicate that the device is in a locked state; a voice prompt can also be issued through a voice module to inform the user of the current locked state of the device.

[0093] When the controller detects that the device is not in the locked state, it will feedback the cleaning prompt information based on the infrared sampling value obtained from the infrared sensor. The controller pre-stores the infrared sampling threshold related to the cleaning prompt, compares the current infrared sampling value with the sampling threshold, and if the infrared sampling value indicates that the residual material in the residual material storage unit has reached the level that needs to be cleaned, the controller will feedback the cleaning prompt information. The presentation method of the cleaning prompt information is similar to the status prompt information, which can be a text prompt, a flashing indicator light, or a voice prompt, etc., to remind the user to clean the residual material storage unit.

[0094] Through the example of this application, before starting the heating, the lock state of the aerosol generating device is detected first, which effectively prevents the heating operation when the device is not suitable for heating, and avoids safety risks caused by misoperation or unauthorized use, such as burns, device damage, etc. For example, when the child lock function is turned on, even if the heating start instruction is accidentally triggered, the heating is prohibited from starting, ensuring the safety of children and users.

[0095] When the aerosol generating device is not locked, the cleaning prompt information can be fed back based on the infrared sampling value to promptly remind the user to clean the residual material storage unit, which helps to keep the inside of the device clean, avoid excessive residual material affecting the aerosol generation effect and the service life of the device, and improve the performance and stability of the device.

[0096] In a possible implementation, the controller is further configured to:

[0097] If it is detected that the aerosol generating device is not in a locked state and the infrared sampling value is less than a predetermined sampling threshold, a cleaning prompt message is fed back.

[0098] In this implementation, when the controller receives a heating start instruction generated by the user through button operation, touch screen operation or distance detection operation, it first detects whether the aerosol generating device is in a locked state. For example, it can be implemented through a hardware circuit related to device locking (such as a microswitch signal for detecting the position of the mechanical lock) or a software flag (such as a lock identification variable set in the device control program).

[0099] If the controller detects that the aerosol generating device is not in a locked state and the infrared sampling value is less than a predetermined sampling threshold, it indicates that a large amount of residual material has accumulated in the residual material storage unit, reaching or exceeding an acceptable range, affecting the aerosol generation effect or device performance. At this time, the controller can provide feedback on cleaning prompts in a variety of ways. For example, a text prompt of "Please clean the residual material storage unit" is displayed on the display screen; the user is reminded by having an indicator light flash at a specific frequency (such as a red indicator light flashing quickly); or a voice prompt of "Too much residual material, please clean it" is issued through the voice broadcast module to inform the user that the residual material storage unit needs to be cleaned.

[0100] If the controller detects that the device is not in a locked state and the infrared sampling value is greater than or equal to the sampling threshold, it indicates that the residual material in the residual material storage unit is within an acceptable range and will not have a significant impact on the heating operation. At this time, the controller can control the aerosol generating unit to start the heating operation, for example, the controller sends a start signal to the aerosol generating unit, activates the heating component, and heats the aerosol matrix according to the preset temperature and time parameters, thereby generating an aerosol for the user to use.

[0101] In the example of this application, based on the automatic judgment and operation of the device lock status and infrared sampling value, the user does not need to manually check the residual material. The device can automatically sense and make corresponding prompts or operations, which simplifies the user's operation process. By deciding whether to start the heating operation based on the infrared sampling value, it helps to maintain the stable performance of the aerosol generating unit, extend the service life of the equipment, and reduce the frequency of repairs or replacement of parts due to equipment failure. In addition, timely and accurate cleaning prompt information allows users to clearly know the cleaning needs of the equipment, avoiding the excessive accumulation of residual materials that affect the aerosol taste, smoke volume and other suction experiences. At the same time, the heating operation can be smoothly started when the residual material is appropriate, ensuring the consistency and fluency of the user's use of the device.

[0102] In a possible implementation, the infrared sensor is further used to detect the residual substance in the residual substance storage unit again after the aerosol generating unit finishes the heating operation, and obtain the corresponding infrared sampling value.

[0103] The controller is also used to feed back cleaning prompt information again if the infrared sampling value is less than the sampling threshold.

[0104] In the example of this application, when the aerosol generating unit completes the heating operation, the infrared sensor can automatically start a new round of detection work, and the infrared emitting diode emits infrared light into the residual material storage unit again. The infrared light propagates in the residual material storage unit and is reflected or scattered after encountering the residual material. The infrared receiving diode continues to receive the infrared light that is reflected or scattered back, and generates a corresponding photocurrent according to the intensity of the received light. It should be understood that in the example of this application, since the heating process will cause more residual material to be generated or the position to change, the infrared light received this time is different from that before heating.

[0105] The signal processing circuit converts the photocurrent generated by the infrared receiving diode into an analog electrical signal, and then amplifies and filters the analog electrical signal to remove interference signals and make the signal more stable. Finally, the processed analog electrical signal is converted into a digital signal to obtain a new round of infrared sampling values. After the controller obtains the infrared sampling value after the heating operation is completed, it compares the newly obtained infrared sampling value with the pre-set sampling threshold.

[0106] If the infrared sampling value is less than the sampling threshold, it indicates that after the heating operation, the accumulation of residual material in the residual material storage unit has further increased and has reached or exceeded the standard for cleaning. At this time, the controller feeds back the cleaning prompt information again. It should be understood that the feedback method of the cleaning prompt information can be the same, similar or different from the previous feedback method, so as to remind the user to clean the residual material storage unit.

[0107] Through the example of this application, by detecting the residual material again after the heating operation is completed, a more comprehensive understanding of the residual situation after the use of the device can be obtained. Since the heating process may cause more residual material to fall, the detection before heating alone cannot accurately reflect the final residual level. By detecting and prompting again after heating, it can ensure that the user is notified in time when the residual material really needs to be cleaned, avoiding the subsequent use experience being affected by excessive residue.

[0108] In a possible implementation, the aerosol generating device further includes:

[0109] A button connected to the controller for receiving a user input of a heating start instruction;

[0110] The mechanical lock is connected to the controller and is used to lock the aerosol generating device or unlock the aerosol generating device, wherein the locked aerosol generating device is in a locked state.

[0111] In the example of this application, the button can provide a direct interface for the user to interact with the device. When the user presses the button, the circuit inside the button changes state such as closing or opening, generates an electrical signal, and transmits it to the controller along the connection line. The controller receives the electrical signal and recognizes it as a user-input instruction to start heating.

[0112] The controller processes the heating start instruction transmitted by the button, and determines whether to perform the heating operation in combination with other current states of the aerosol generating device (such as whether it is in a locked state). For example, if the aerosol generating device is not locked, the controller further instructs the heating component to start working according to a predetermined program to achieve heating of the aerosol substrate.

[0113] In the example of this application, the mechanical lock is connected to the controller, and when the user operates the mechanical lock to put it in the locked position, the change in the mechanical structure of the lock will trigger a feedback signal to the controller. Optionally, the feedback signal can be an electrical signal generated by a device such as a micro switch, informing the controller that the aerosol generating device has entered a locked state at this time. After receiving the lock signal, the controller adjusts the operating logic of the aerosol generating device to prohibit risky operations such as starting heating. Conversely, when the user operates the mechanical lock to unlock, the lock will also send an unlock signal to the controller. After the controller recognizes the unlock signal, it adjusts the state of the aerosol generating device to an operable state, allowing the user to normally start the heating operation by pressing a button or the like.

[0114] In the example of this application, by setting a mechanical lock in the aerosol generating device, the device can be effectively prevented from being started in unexpected circumstances. For example, when the aerosol generating device is carried, if it is not locked, the heating may be started due to the accidental touch of the button, which poses a safety hazard. By locking the device with a mechanical lock, the heating operation can only be performed after unlocking, which greatly reduces the risk of misoperation.

[0115] Especially for some aerosol generating devices that may have high-temperature components, the locked state can prevent children or people who are not familiar with the operation from arbitrarily starting the device, prevent accidents such as burns, and protect the personal safety of users. In addition, by preventing misoperation and unauthorized operation, the user's controllability of device operation is enhanced, and the damage to the device due to abnormal startup or improper use is reduced, which helps to extend the service life of the device and reduce maintenance costs.

[0116] In an optional example, the aerosol generating device further includes:

[0117] The battery assembly is arranged inside the aerosol generating device and is connected to various components in the aerosol generating device through a power cord and connected to an external power source through a charging interface, and is used to convert the electric energy obtained from the external power source into voltage and current used by various components.

[0118] Optionally, the battery assembly can convert the electrical energy obtained from an external power source into voltage and current suitable for various components of the device. Different components may require power supplies of different specifications. For example, the heating element of the aerosol generating unit requires a higher voltage to generate enough heat to heat the aerosol matrix, while the sensor and control chip only require a lower and stable voltage. The battery assembly is integrated with a power management circuit that can convert and adjust the input electrical energy according to the needs of each component. For example, the high voltage of the external power supply is converted into a low voltage suitable for the operation of the sensor and control chip through a buck converter, and sufficient electrical energy is provided for the heating element that requires a high voltage through a boost converter.

[0119] In another optional example, the aerosol generating device further comprises:

[0120] The battery power detection circuit is connected to the battery assembly and the controller to detect the remaining power of the battery assembly in real time.

[0121] After the controller obtains the remaining battery power information, it can adopt different strategies according to the power situation. For example, when the power is low, the controller can prompt the user to charge in time through the display screen, or reduce certain functions of the device (such as reducing the heating power) to extend the use time of the device, ensuring that the device can still operate normally for a period of time when the power is low, avoiding the user experience affected by sudden power outages.

[0122] Through the example of this application, the stable power supply of the battery assembly ensures that all components of the device can operate normally, and the real-time power information feedback from the battery power detection circuit enables the controller to reasonably allocate power, further ensuring that the device can operate stably under various power conditions.

[0123] This application example provides an example of a control method for an aerosol generating device, please refer to Figure 2 As shown, Figure 2 A schematic flow chart of a control method for an aerosol generating device provided by the present application is shown. As an example but not a limitation, the method can be applied to or run in an aerosol generating device. The method includes:

[0124] S201, using an infrared sensor to detect residual substances in a residual substance storage unit to obtain corresponding infrared sampling values, wherein the residual substance storage unit is arranged below the aerosol generating unit and connected to the aerosol generating unit, and is used to receive and contain the residual substances in the aerosol generating unit; the aerosol generating unit is arranged inside the aerosol generating device, and is used to place an aerosol matrix, and generate an aerosol by heating the aerosol matrix.

[0125] S202, feeding back cleaning prompt information according to the infrared sampling value, wherein the cleaning prompt information is used to instruct to clean the residual material storage unit.

[0126] Optionally, in the example of the present application, the aerosol generating unit is used to place an aerosol matrix, for example, a mixture of herbs such as mint, licorice, cloves, chrysanthemum, etc., and heat the aerosol matrix through a built-in heating component to atomize the substance in the aerosol matrix without burning, thereby forming an aerosol that can be used by users.

[0127] Optionally, in one example, the heating mechanism adopted by the aerosol generating unit may be a heat not burn (HNB) technology, which can release the odor components of the aerosol matrix at a lower temperature while reducing the harmful substances produced by traditional combustion methods.

[0128] Optionally, the residual material storage unit is disposed below the aerosol generating unit and is connected to the aerosol generating unit. During the operation of the aerosol generating unit, the residual gas after heating gradually cools down to become attachments, and adheres to the inner wall of the aerosol generating unit, and then deposits to the bottom of the aerosol generating unit; during the plugging and unplugging process of some aerosol matrices, a small amount of residual material will fall to the bottom of the aerosol generating unit. By providing a diversion channel at the bottom of the aerosol generating unit, etc., the residual material remaining at the bottom of the aerosol generating unit is collected in the residual material storage unit (i.e., a cleaning box, a cleaning cup), so that the residual material storage unit can receive and contain these residual materials.

[0129] Optionally, in the example of the present application, the infrared sensor is installed at a predetermined height position of the residual material storage unit. The predetermined height position can be set based on the comprehensive requirements of the residual material accumulation and the equipment cleaning requirements. For example, when the residual material accumulates to a certain height and affects the performance of the aerosol generating device, the position corresponding to the height is the installation position of the infrared sensor. Figure 1 As shown, when the infrared sensor is working, it continuously emits infrared light in the horizontal direction as indicated by the dotted line, and receives the reflected infrared light.

[0130] In this application example, the controller is connected to the infrared sensor, and the controller pre-stores judgment logic and threshold data obtained based on experiments and actual tests. After receiving the infrared sampling value sent by the infrared sensor, the controller analyzes and judges the infrared sampling value according to the preset judgment logic and threshold data, and then determines whether to feedback the cleaning prompt information.

[0131] When the infrared light emitted by the infrared sensor encounters the residual material in the residual material storage unit, it is reflected, scattered, and other phenomena occur. When there is less residual material, most of the infrared light can smoothly reach the shell position of the residual material storage unit farther away and reflect back to the infrared sensor. At this time, the intensity of the infrared light received by the infrared sensor is higher, and the corresponding infrared sampling value is also larger. As the residual material continues to accumulate, when the residual material in the residual material storage unit reaches or exceeds the predetermined height, more infrared light is absorbed or scattered by the residual material, and the intensity of the infrared light returned to the sensor is weakened, resulting in a decrease in the infrared sampling value.

[0132] In an optional embodiment, after the controller receives the infrared sampling value sent by the infrared sensor, it compares the infrared sampling value with a preset sampling threshold. The sampling threshold is determined based on a large number of experiments and actual usage experience, and indicates the critical value of the infrared sampling value corresponding to when the residual material reaches the level that needs to be cleaned.

[0133] If the infrared sampling value is less than or equal to the sampling threshold, it indicates that the residual material has accumulated to the extent that it needs to be cleaned, and the controller will trigger the feedback mechanism of the cleaning prompt information. Optionally, the cleaning prompt information can be presented to the user in a variety of ways, for example, by displaying a text prompt of "Please clean the cleaning box" on the display screen; or by controlling the indicator light on the device to flash, such as the red indicator light flashing at a specific frequency; or by using the voice module to play a voice prompt of "Too much residual material, please clean" to remind the user to clean the residual material storage unit.

[0134] This application scheme uses the cooperation of infrared sensors and controllers to realize the intelligent monitoring and prompting of the residual material storage unit cleaning by the aerosol generating device. There is no need for the user to manually check or judge. The device automatically senses the residual material situation and gives prompts, which improves the intelligence of the device and the convenience of user use. The infrared sensor detects the accumulation height of the residual material in real time, converts it into an infrared sampling value and transmits it to the controller; the controller determines the amount of residual material based on the infrared sampling value, and then, when the infrared sampling value reaches the sampling threshold for prompting cleaning, the controller promptly feedbacks the cleaning prompt information. The user does not need to rely on experience or guesswork to clearly know the degree of contamination in the residual material storage unit. The user can accurately grasp the cleaning time, avoid excessive cleaning or untimely cleaning, improve cleaning efficiency, and solve the problems of low cleaning efficiency and insufficient cleaning health.

[0135] In one possible implementation, Figure 3 As shown, cleaning prompt information is fed back based on the infrared sampling value, including:

[0136] S301, in response to receiving a user's instruction to start heating, detecting whether the aerosol generating device is in a locked state, wherein the instruction to start heating is generated by at least one of a key operation, a touch screen operation, and a distance detection operation;

[0137] S302: If it is detected that the aerosol generating device is not in a locked state and the infrared sampling value is less than a predetermined sampling threshold, a cleaning prompt message is fed back.

[0138] Optionally, in the example of the present application, the user can send a start heating instruction to the aerosol generating device through a variety of interactive methods, including key operation, touch screen operation and distance detection operation.

[0139] Optionally, in one example, the aerosol generating device is equipped with a physical button, and when the user presses the button, the circuit inside the button is closed, generating an electrical signal, which is transmitted along the connecting line to the controller, and the controller recognizes it as a command to start heating.

[0140] Optionally, in another example, the aerosol generating device is equipped with a touch screen, and the user performs specific touch operations on the screen, such as clicking a heating icon or executing a preset gesture. After the touch screen senses the touch action, it converts it into an electrical signal and transmits it to the controller as a command to start heating.

[0141] Optionally, in another example, a distance sensor, such as an infrared distance sensor or an ultrasonic distance sensor, is installed in the aerosol generating device. When it is detected that the user's hand or other object approaches a preset distance range, the distance sensor outputs a corresponding signal to the controller, and the signal is regarded as a heating start instruction.

[0142] In the example of the present application, after receiving the instruction to start heating, the controller immediately detects whether the aerosol generating device is in a locked state. The locked state may be triggered by a variety of reasons, such as the child lock function is turned on, the device is in a fault protection state, etc.

[0143] In one example, if the aerosol generating device uses a hardware locking method such as a mechanical lock or an electronic lock, for example, when the mechanical lock is in the locked position, a micro switch is triggered, and the electrical signal generated by the micro switch is read by the controller, thereby determining that the device is in a locked state. In another example, the aerosol generating device can set the lock state through software. The controller checks the internal status flag or a specific register value to determine whether the device is locked by software.

[0144] When the controller detects that the device is not in a locked state, it will feedback cleaning prompt information based on the infrared sampling value obtained from the infrared sensor. The controller pre-stores the infrared sampling threshold related to the cleaning prompt, compares the current infrared sampling value with the sampling threshold, and if the infrared sampling value indicates that the residual material in the residual material storage unit has reached the level that needs to be cleaned, the controller will feedback the cleaning prompt information. The presentation method of the cleaning prompt information is similar to the status prompt information, which can be a text prompt, a flashing indicator light, or a voice prompt, etc., to remind the user to clean the residual material storage unit.

[0145] Through the example of this application, before starting the heating, the lock state of the aerosol generating device is detected first, which effectively prevents the heating operation when the device is not suitable for heating, and avoids safety risks caused by misoperation or unauthorized use, such as burns, device damage, etc. For example, when the child lock function is turned on, even if the heating start instruction is accidentally triggered, the heating is prohibited from starting, ensuring the safety of children and users.

[0146] When the aerosol generating device is not locked, the cleaning prompt information can be fed back based on the infrared sampling value to promptly remind the user to clean the residual material storage unit, which helps to keep the inside of the device clean, avoid excessive residual material affecting the aerosol generation effect and the service life of the device, and improve the performance and stability of the device.

[0147] In this implementation, when the controller receives a heating start instruction generated by the user through button operation, touch screen operation or distance detection operation, it first detects whether the aerosol generating device is in a locked state. For example, it can be implemented through a hardware circuit related to device locking (such as a microswitch signal for detecting the position of the mechanical lock) or a software flag (such as a lock identification variable set in the device control program).

[0148] If the controller detects that the aerosol generating device is not in a locked state and the infrared sampling value is less than a predetermined sampling threshold, it indicates that a large amount of residual material has accumulated in the residual material storage unit, reaching or exceeding an acceptable range, affecting the aerosol generation effect or device performance. At this time, the controller can provide feedback on cleaning prompts in a variety of ways. For example, a text prompt of "Please clean the residual material storage unit" is displayed on the display screen; the user is reminded by having an indicator light flash at a specific frequency (such as a red indicator light flashing quickly); or a voice prompt of "Too much residual material, please clean it" is issued through the voice broadcast module to inform the user that the residual material storage unit needs to be cleaned.

[0149] In the example of this application, based on the automatic judgment and operation of the device lock status and infrared sampling value, the user does not need to manually check the residual material. The device can automatically sense and make corresponding prompts or operations, which simplifies the user's operation process. By deciding whether to start the heating operation based on the infrared sampling value, it helps to maintain the stable performance of the aerosol generating unit, extend the service life of the equipment, and reduce the frequency of repairs or replacement of parts due to equipment failure. In addition, timely and accurate cleaning prompt information allows users to clearly know the cleaning needs of the equipment, avoiding the excessive accumulation of residual materials that affect the aerosol taste, smoke volume and other suction experiences. At the same time, the heating operation can be smoothly started when the residual material is appropriate, ensuring the consistency and fluency of the user's use of the device.

[0150] In one possible implementation, Figure 3 As shown, the method also includes:

[0151] S303, if it is detected that the aerosol generating device is not in a locked state and the infrared sampling value is greater than or equal to the sampling threshold, controlling the aerosol generating unit to start a heating operation;

[0152] S304, after the aerosol generating unit finishes the heating operation, instructing the infrared sensor to detect the residual material in the residual material storage unit again to obtain a corresponding infrared sampling value, and

[0153] S305: If the infrared sampling value is less than the sampling threshold, the cleaning prompt information is fed back again.

[0154] In the example of this application, if the controller detects that the device is not in a locked state and the infrared sampling value is greater than or equal to the sampling threshold, it indicates that the residual material in the residual material storage unit is within an acceptable range and will not have a significant impact on the heating operation. At this time, the controller can control the aerosol generating unit to start the heating operation, for example, the controller sends a start signal to the aerosol generating unit, activates the heating component, and heats the aerosol matrix according to the preset temperature and time parameters, thereby generating an aerosol for the user to use.

[0155] In the example of this application, when the aerosol generating unit completes the heating operation, the infrared sensor can automatically start a new round of detection work, and the infrared emitting diode emits infrared light into the residual material storage unit again. The infrared light propagates in the residual material storage unit and is reflected or scattered after encountering the residual material. The infrared receiving diode continues to receive the infrared light that is reflected or scattered back, and generates a corresponding photocurrent according to the intensity of the received light. It should be understood that in the example of this application, since the heating process will cause more residual material to be generated or the position to change, the infrared light received this time is different from that before heating.

[0156] The signal processing circuit converts the photocurrent generated by the infrared receiving diode into an analog electrical signal, and then amplifies and filters the analog electrical signal to remove interference signals and make the signal more stable. Finally, the processed analog electrical signal is converted into a digital signal to obtain a new round of infrared sampling values. After the controller obtains the infrared sampling value after the heating operation is completed, it compares the newly obtained infrared sampling value with the pre-set sampling threshold.

[0157] If the infrared sampling value is less than the sampling threshold, it indicates that after the heating operation, the accumulation of residual material in the residual material storage unit has further increased and has reached or exceeded the standard for cleaning. At this time, the controller feeds back the cleaning prompt information again. It should be understood that the feedback method of the cleaning prompt information can be the same, similar or different from the previous feedback method, so as to remind the user to clean the residual material storage unit.

[0158] Through the example of this application, by detecting the residual material again after the heating operation is completed, a more comprehensive understanding of the residual situation after the use of the device can be obtained. Since the heating process may cause more residual material to fall, the detection before heating alone cannot accurately reflect the final residual level. By detecting and prompting again after heating, it can ensure that the user is notified in time when the residual material really needs to be cleaned, avoiding the subsequent use experience being affected by excessive residue.

[0159] In one possible implementation, Figure 3 As shown, the method also includes:

[0160] S306: If it is detected that the aerosol generating device is in a locked state, the start-up heating operation is prohibited and status prompt information is fed back, wherein the status prompt information is used to indicate that the aerosol generating device is in a locked state.

[0161] In this application example, if the controller detects that the aerosol generating device is in a locked state, in order to ensure the safety of the aerosol generating device and comply with the preset rules, the start-up heating operation is prohibited. At the same time, the controller will feedback the status prompt information to the user, for example, a prompt box "The device is locked, please unlock it before operation" will pop up on the display screen of the aerosol generating device, or the indicator light of the aerosol generating device will flash and a voice prompt "The device is locked" will be heard.

[0162] Through the embodiments of the present application, when receiving a heating start instruction, the lock state of the aerosol generating device is first detected to prevent heating operations when the device is in an unsafe or inappropriate state. For example, when the child lock function of the device is turned on to prevent children from misoperating, the device lock can prevent children from accidentally starting the heating, reducing potential safety risks such as burns, fire, etc.

[0163] In the example of this application, when the aerosol generating device is in a locked state, status prompt information is promptly fed back to allow the user to clearly understand the current status of the device, thereby preventing the user from repeatedly trying to start the heating operation due to lack of understanding of the situation, thereby reducing user confusion and unnecessary operating troubles.

[0164] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
