[0031] Heat-not-burn (HNB) aerosol-generating devices commonly face the problem of airway contamination accumulation. Traditional devices often use simple absorbent pads to passively absorb liquid oil. However, relying solely on physical contact, they are unable to remove stubborn residues adhering to the airway walls, leading to the generation of unpleasant gases and oil leakage, which impacts both taste and device life.

[0032] Some equipment requires manual disassembly and cleaning, which is cumbersome, incomplete, and leads to high maintenance costs. While a few devices attempt to use heat-assisted cleaning, these lack precise temperature control, often causing damage to components due to excessively high temperatures, or incomplete vaporization of oil contaminants due to excessively low temperatures.

[0033] In order to solve the technical problem that the aerosol generating device in the above-mentioned related technologies cannot remove the residual substances attached to the airway wall, it can also realize automatic cleaning and precise temperature control to avoid damage to components due to excessively high temperature or incomplete gasification of oil pollution due to excessively low temperature. The embodiment of the present application provides an embodiment of an aerosol generating device, please refer to Figure 1 As shown, Figure 1 1 shows a schematic structural diagram of an aerosol generating device provided by the present application. The aerosol generating device includes a housing 100 and further includes: The heating element 101 is disposed outside the heating chamber 102 in the housing 100 and is used to heat the aerosol matrix or residual substances in the heating chamber.

[0034] The adsorption element 103 is detachably placed inside the heating chamber 102 , and is used to adsorb volatile substances in the residual substances when the heating element 101 performs a heating operation on the residual substances inside the heating chamber 102 .

[0035] The controller 104 (arranged inside the housing, for example, a control board in a PCB assembly, installed at a position such as Figure 2 As shown), connected to the heating element 101, it is configured to perform: when a cleaning instruction is received, control the heating element to perform a heating operation on the residual material inside the heating chamber, and the heating temperature of the heating operation is greater than the melting point temperature of the residual material and less than the temperature resistance temperature of the adsorption element; when the heating temperature of the heating operation reaches a predetermined temperature range and the heating time reaches a predetermined time, control the heating element to stop the heating operation.

[0036] In some embodiments, the housing of the aerosol generating device forms an interior mounting space for various components, while also providing structural support and protection for the device. For example, the housing can be made of a high-temperature-resistant and strong material, such as polycarbonate or aluminum alloy, to provide excellent protection for the various components within the aerosol generating device. A heating chamber is disposed within the housing. The heating chamber has a hollow cavity structure. The structural dimensions and shape of the heating chamber are compatible with the aerosol substrate to be heated and the adsorption element subsequently used for cleaning, ensuring that the aerosol substrate can be smoothly placed for normal operation while also facilitating the insertion and removal of the adsorption element. In some embodiments, the heating element is disposed outside the heating chamber, and specifically may be a heating wire surrounding the periphery of the heating chamber, or a heating plate attached to the outer wall of the heating chamber.

[0037] In some embodiments, the heating element is connected to the controller via a wire and receives control signals from the controller to perform heating operations. The power of the heating element can be adjusted according to actual needs to meet the heating requirements of different substances within the heating chamber. It can be used to heat the aerosol substrate within the heating chamber to generate aerosols, and can also be used in cleaning mode to heat residual substances such as oil stains within the heating chamber to induce a state change in the residual substances.

[0038] In some embodiments, the adsorption element is placed inside the heating chamber in a detachable manner. The specific material can be a porous medium, such as cotton material or porous ceramic, and has good temperature resistance, for example, a temperature resistance greater than 180°C, to ensure that it will not be damaged by high temperature during the heating operation. The adsorption element can be in the shape of a columnar through hole or channel structure, and its size matches the cavity of the heating chamber, and can be stably placed in the heating chamber. When the heating element heats the residual material inside the heating chamber, the volatile substances formed by the volatilization of the residual material after heating will move toward the adsorption element, and the adsorption element can effectively adsorb these volatile substances by virtue of the capillary phenomenon generated by the porous structure, thereby achieving the purpose of cleaning the heating chamber. In some embodiments, the controller can be a microprocessor or single-chip microcomputer, located in a suitable location within the housing and connected to the heating element and other related control components via wires. The controller is pre-programmed with corresponding control programs and parameters to achieve precise control of the heating operation. When the controller receives a cleaning instruction, it can control the heating element to start heating the residual material inside the heating chamber. Optionally, the cleaning instruction can be triggered in a variety of ways, such as the user operating a physical button on the device, or sending an instruction through the touch screen of the aerosol generating device. During the heating process, the controller can strictly control the heating temperature to ensure that the heating temperature is greater than the melting point of the residual material. Only in this way can the residual material be transformed from a solid or semi-solid state to a liquid or gaseous state after heating, facilitating subsequent adsorption; at the same time, the heating temperature must be lower than the temperature resistance of the adsorption element to avoid damage to the adsorption element due to excessive temperature. The controller also has a preset temperature range and a preset duration. These two parameters were determined through multiple experiments based on the characteristics of the residual material and the performance of the adsorption element. When the heating temperature reaches the preset temperature range and the heating time reaches the preset duration, the controller determines that the residual material has fully evaporated and is adsorbed by the adsorption element. It then issues a command to the heating element to stop heating, completing the cleaning process. For example, after a cleaning device has been used for a period of time, a certain amount of oil residue (the residual substance is oil) accumulates inside the heating chamber. When the user wants to clean the residual oil, they place the adsorption element into the heating chamber and then send a cleaning command to the controller by operating the cleaning button on the device. After receiving the cleaning command, the controller controls the heating element to begin heating. When the heating temperature reaches a predetermined temperature range, such as 120-150°C, and the heating time reaches a predetermined time, such as 8-12 minutes, the controller determines that the residual substance has fully volatilized and is adsorbed by the adsorption element. At this time, the controller controls the heating element to stop heating. At this point, the volatile substances in the oil have been adsorbed by the adsorption element. The user removes the adsorption element from the heating chamber, completing the cleaning of the heating chamber. Using the aerosol generating device provided in the embodiments of the present application, it is possible to effectively remove substances such as oil residue inside the heating chamber in cleaning mode, preventing the accumulation of residual substances from affecting the user experience and service life of the aerosol generating device.

[0039] In one possible implementation, the aerosol generating device further includes: an infrared sensor disposed within the housing and positioned outside the heating chamber, configured to transmit infrared light into the interior of the heating chamber and receive reflected light, and to determine whether the interior of the heating chamber contains an aerosol matrix or an adsorption element based on the reflected light, wherein the heating chamber contains either the aerosol matrix or the adsorption element at the same time; The controller is connected to the infrared sensor and is further configured to execute: when the infrared sensor determines that the interior of the heating chamber is an adsorption element, determine that a cleaning instruction is received.

[0040] In some embodiments, the aerosol generating device includes, in addition to the aforementioned housing, heating element, adsorption element, and controller, an infrared sensor to automatically trigger a cleaning instruction, thereby enhancing the intelligence of the aerosol generating device. In some embodiments, the infrared sensor is located within the housing and outside the heating chamber. The installation position must ensure that it can stably transmit infrared light into the heating chamber and effectively receive reflected light from the interior of the heating chamber. For example, the infrared sensor can be embedded in the side wall of the housing corresponding to the edge of the heating chamber opening, so that the direction of infrared light emission is at a certain angle to the axis of the heating chamber, thereby covering the main storage space within the heating chamber and ensuring accurate recognition of objects placed in the heating chamber. It should be understood that in the embodiments of this application, the core function of the infrared sensor is to distinguish whether the aerosol matrix or the adsorption element is placed inside the heating chamber. Due to the differences in the materials and structures of the aerosol matrix and the adsorption element, their reflection characteristics for infrared light are also different. By detecting changes in parameters such as the intensity and wavelength of the reflected light, the infrared sensor can accurately determine the type of object currently contained in the heating chamber. It should be noted that the heating chamber can only accommodate one of the aerosol matrix and the adsorption element at a time, so the infrared sensor's recognition result is unique. In some embodiments, the controller establishes a connection with the infrared sensor and receives identification signals transmitted by the infrared sensor in real time. When the infrared sensor determines that an adsorption element is placed within the heating chamber, it transmits this determination in the form of an electrical signal to the controller. Upon receiving this electrical signal, the controller immediately determines that a cleaning instruction has been received and automatically initiates cleaning mode without requiring additional manual operation by the user. In an optional embodiment, the specific working process is as follows: When the user places the adsorption element into the heating chamber, the infrared sensor emits infrared light. The light is reflected after hitting the surface of the adsorption element, and the reflected light is received by the infrared sensor. The infrared sensor analyzes the reflected light. Due to the porous structure and material properties of the adsorption element, the characteristics of the reflected light from the adsorption element are significantly different from those of the aerosol matrix. Based on this, the infrared sensor determines that there is an adsorption element in the heating chamber and feeds this determination result back to the controller. In response to this determination result, the controller directly triggers the cleaning process and controls the heating element to heat the residual material in the heating chamber according to the preset heating parameters. The subsequent heating temperature control, heating stop judgment, and other processes are consistent with the aforementioned embodiment. Through the coordinated work of the infrared sensor and the controller, the aerosol generating device can automatically trigger the cleaning instruction, simplifying the user's operation steps. At the same time, it ensures that the cleaning mode is automatically started in the correct usage scenario, further improving the convenience and reliability of equipment cleaning, and effectively avoiding the accumulation of residual substances caused by the user forgetting to trigger the cleaning instruction.

[0041] In one possible implementation, the aerosol generating device further includes a physical button and / or a display screen, wherein the physical button is arranged on the shell; the display screen is arranged on the shell and is used to display at least one touch button.

[0042] A controller is connected to a physical button and / or a display screen, and is configured to execute: determining that a cleaning instruction has been received in response to a user clicking a physical button; or determining that a cleaning instruction has been received in response to a user touching a cleaning button in a touch button.

[0043] In this embodiment, the aerosol generating device is further equipped with physical buttons and / or display screens based on the original structure, providing users with an interactive way to manually trigger cleaning instructions, which complements the automatic triggering method of the infrared sensor and enhances the flexibility of device operation. In some embodiments, physical buttons are located on the outer surface of the housing, specifically in a position convenient for user operation, such as on the side or top of the housing. The button surface can be designed with raised or recessed structures to facilitate tactile identification by the user. Conductive contacts are located within the physical buttons. When a user clicks the physical button, the contacts close, generating an electrical signal that is directly transmitted to the controller. In some embodiments, a display screen is also mounted on the outer surface of the housing. For example, it can be a touch screen display, the size of which is adapted to the housing. It can not only clearly display device status information (such as the current mode, heating temperature, remaining cleaning time, etc.), but also receive user instructions through touch interaction. At least one touch button will be displayed on the display screen, including a cleaning button / button specifically for triggering the cleaning function. The cleaning button can be clearly indicated by an icon or text label (such as "Clean", "Start Cleaning") and is in a waiting state when not triggered. When touched, it will provide feedback of successful operation through color change or slight vibration. In some embodiments, the controller establishes electrical connections with the physical button and / or the display screen, respectively, and monitors in real time the click signals from the physical button and the touch signals from the touch buttons on the display screen. When a user needs to manually activate the cleaning mode, it can be triggered in two ways: first, the user presses the physical button, which closes the internal contacts of the physical button and generates an electrical signal. Upon receiving the electrical signal corresponding to the click operation, the controller immediately determines that a cleaning instruction has been received. Second, the user touches the cleaning button on the display screen with a finger. The display screen converts the touch position information into an electrical signal and transmits it to the controller. The controller recognizes that the signal corresponds to a touch operation on the cleaning button and similarly determines that a cleaning instruction has been received. In some embodiments, regardless of whether the cleaning instruction is triggered by a physical button or a touch button, after the controller determines that the cleaning instruction has been received, the subsequent cleaning process executed is consistent with the aforementioned embodiment: the heating element is controlled to heat the residual material in the heating chamber according to the target heating curve (heating time, heating temperature), the heating temperature is strictly controlled (higher than the melting point of the residual material and lower than the temperature resistance of the adsorption element), and after reaching the predetermined temperature range and heating time, the heating element is controlled to stop working. Furthermore, the display screen updates the heating progress in real time during the cleaning process, for example, by displaying the remaining time through a progress bar or digital countdown. When cleaning is complete, the screen displays a prompt message such as "Cleaning Completed." Meanwhile, the physical buttons can also flash (if the buttons have integrated indicator lights) to provide auxiliary prompts, ensuring that the user is promptly informed of the cleaning status. By configuring the physical buttons and / or the display screen, users can proactively trigger the cleaning operation based on their actual needs. This is particularly useful when the infrared sensor is unable to operate normally due to special circumstances (such as recognition errors caused by surface stains). This ensures reliable triggering of the cleaning function, further enhancing the practicality and user experience of the aerosol generating device.

[0044] In a possible implementation, the aerosol generating device further includes: a prompt unit, disposed in the housing, for outputting a prompt message.

[0045] The controller is connected to the prompt unit and is also configured to execute: when the heating temperature of the heating operation reaches a predetermined temperature range and the heating time reaches a predetermined time, the control prompt unit outputs a first prompt message, wherein the first prompt message is used to instruct the user to remove the adsorption element from the heating chamber.

[0046] In this embodiment, the aerosol generating device further includes a prompt unit, which is disposed within the housing. The specific installation location can be determined based on the overall structural layout of the device, such as on a side near the heating chamber or within the cavity area within the housing, to ensure that prompt messages are effectively transmitted to the user. The prompt unit can be implemented in various forms, such as a buzzer, a vibration motor, an LED indicator light, or a text / icon prompt module integrated with the aforementioned display. Its core function is to output prompt messages to the user under specific conditions, enabling information exchange between the device and the user. In some embodiments, the controller is electrically connected to the prompt unit and can send control signals to the prompt unit according to preset control logic, thereby driving the prompt unit to perform the corresponding prompt operation. Specifically, when the controller monitors that the heating temperature of the heating operation reaches a predetermined temperature range (e.g., 120-150°C) and the heating time reaches a predetermined time (e.g., 8-12 minutes), it determines that the current cleaning process is complete and the residual material has fully volatilized and been adsorbed by the adsorption element. At this time, the controller sends a control instruction to the prompt unit, instructing it to output a first prompt message, which specifically instructs the user to remove the adsorption element from the heating chamber. In some embodiments, if the prompt unit is a buzzer, the first prompt message may be manifested as a sound of a specific frequency, such as three consecutive short "beep" sounds, to attract the user's attention; if it is a vibration motor, the first prompt message may be manifested as a vibration lasting 2-3 seconds, reminding the user through tactile feedback; if it is an LED indicator light, the indicator light can be controlled to flash in a specific manner, such as a red indicator light flashing once per second for 5 seconds; if the prompt unit is integrated with the display screen, a text prompt message of "Cleaning is completed, please remove the adsorption element" can be displayed on the display screen, and icons (such as a schematic diagram of the adsorption element and an outward arrow) can be used to enhance the intuitiveness of the prompt. By setting a prompt unit in the aerosol generating device, clear operating instructions can be delivered to the user as soon as the cleaning process is completed, avoiding the adsorption element from being left in the heating chamber for a long time due to the user not knowing the cleaning completion status in time, and preventing the performance of the adsorption element from being affected by the residual temperature in the heating chamber and changing, thereby further improving the convenience and user experience of users using the aerosol generating device.

[0047] In a possible implementation, the controller is further configured to execute: Obtain the melting point temperature of the residual substance in advance.

[0048] The predetermined temperature range is determined according to the melting point temperature; wherein the state of the residual substance at room temperature is solid or semi-solid, and when the heating temperature reaches the predetermined temperature range and the heating time reaches the predetermined time, the state of the residual substance is liquid or gaseous.

[0049] In this embodiment, the controller is further configured to have the function of pre-acquiring the melting point temperature of the residual substance and determining the predetermined temperature range accordingly, so as to achieve precise control of the heating operation and ensure that the residual substance can be efficiently converted into a state that can be adsorbed. In some embodiments, the residual material primarily consists of oil accumulated within the passages or airways of the heating chamber. At room temperature, it is solid or semi-solid. The intermolecular forces between these substances are strong, making complete removal difficult through physical adsorption alone. However, when the heating temperature reaches the melting point of the residual material, the intermolecular forces weaken, and the material's state changes, liquefying or vaporizing. Therefore, the controller must pre-determine the melting point of the residual material. This can be accomplished by pre-programming the melting point data for common oils (e.g., a specific value within the range of 100-120°C determined experimentally) into the controller's storage module before the aerosol generating device leaves the factory. Alternatively, the aerosol generating device can be connected to a network to obtain melting point parameters for different types of oils from a cloud database. Alternatively, the melting point parameters can be user-entered to accommodate diverse usage scenarios. In some embodiments, after obtaining the melting point of the residual substance, the controller determines a predetermined temperature range for the heating operation based on the melting point. Specifically, the lower limit of the predetermined temperature range must be higher than the melting point of the residual substance to ensure that the residual substance can overcome the intermolecular forces during the heating process and achieve a state transition. At the same time, the upper limit of the range must be lower than the heat resistance of the adsorption element (e.g., if the adsorption element has a heat resistance greater than 180°C, the upper limit of the predetermined temperature range can be set to 150-170°C) to prevent damage to the adsorption element due to high temperatures. For example, if the melting point of the residual substance is detected to be 110°C, the controller may determine the predetermined temperature range to be 120-150°C. This range is both higher than the melting point to ensure that the substance can be effectively converted, and provides a safety margin to prevent excessive temperatures from affecting equipment components. In some embodiments, during the actual cleaning process, when the heating temperature reaches the predetermined temperature range and the heating time reaches a predetermined duration (e.g., 8-15 minutes depending on the amount of residual material), the residual material, which is solid or semi-solid at room temperature, undergoes a phase transition due to continued heating, transforming into a more fluid liquefied state or a more easily adsorbed vaporized state. Residual material in the liquefied state can be attracted to the adsorption element due to its inherent fluidity, while residual material in the vaporized state is captured by the porous structure of the adsorption element as it moves with the airflow. Both phase transitions can significantly improve cleaning efficiency. In some embodiments, by performing the above operations, the controller makes the setting of the heating temperature no longer rely on fixed parameters, but is dynamically adjusted based on the inherent properties of the residual substance. Regardless of how the composition or accumulation amount of the residual substance changes, the heating operation can specifically promote its state change, thereby enhancing the reliability and adaptability of the equipment's cleaning function.

[0050] In one possible implementation, the structure of the adsorption element is a channel structure, and the channel structure is configured such that the inner diameter of the channel at the first end is smaller than the inner diameter of the channel at the second end, wherein the first end is the end close to the base of the heating chamber, and the second end is the end away from the base of the heating chamber.

[0051] In this embodiment, the adsorption element adopts a channel structure design, and the overall shape is adapted to the internal space of the heating chamber to ensure that an efficient airflow interaction environment is formed with the heating chamber during the cleaning process. Specifically, the channel structure of the adsorption element presents the characteristic of different inner diameters at both ends, e.g. Figure 3As shown, the channel inner diameter is smaller at the end closest to the heating chamber base (i.e., the first end), while it is larger at the end farther from the base (i.e., the second end). This "smaller at the bottom, larger at the top" structural design is based on airflow dynamics and adsorption efficiency. For example, the channel inner diameter at the first end can be set to 0.5-2mm, and the channel inner diameter at the second end can be set to 2-5mm. The difference in inner diameter between the two ends is determined based on the volume of the heating chamber and the expected airflow velocity, typically ensuring stable, directional airflow within the channel. In some embodiments, when the heating element heats the residual material inside the heating chamber, the volatile material (including liquefied and vaporized states) formed by the residual material after being heated will form an upward airflow trend in the heating chamber, such as Figure 3 The airflow direction is shown. Because the inner diameter of the channel at the first (lower) end of the adsorption element is smaller, according to the principles of fluid mechanics, the airflow velocity here is relatively high, creating a certain drainage effect, directing the volatile substances generated in the heating area below upward. The larger inner diameter of the channel at the second (upper) end reduces resistance to airflow and avoids airflow congestion caused by the narrow channel, allowing volatile substances to enter the adsorption element smoothly. At the same time, this channel structure, combined with the porous media properties of the adsorption element, further enhances the capillary effect. The smaller inner diameter of the first end channel enhances capillary suction, more efficiently drawing residual substances near the base of the heating chamber (especially liquefied oil) into the channel interior. The larger inner diameter of the second end channel provides more space for the adsorbed substances, reducing the impact of adsorption saturation on cleaning effectiveness. In addition, the porous structure of the channel inner wall forms a continuous capillary force gradient as the inner diameter gradually changes, driving volatile substances from the first end to the second end. In some embodiments, when assembling the adsorption element, the first end of the adsorption element needs to maintain an appropriate distance from the heating chamber base (typically 2-5 mm) to prevent the channel entrance from being blocked by the base, ensuring smooth entry of volatile substances into the channel. The second end can be slightly higher than the center of the heating chamber to allow the rising airflow to naturally converge into the channel. This structural design eliminates the need for an additional power device and optimizes airflow direction and adsorption efficiency solely through its inherent structural features. This synergistic effect, combined with the controller's heating control logic, improves cleaning speed while reducing the structural complexity and energy consumption of the aerosol generating device.

[0052] In one possible implementation, the adsorption element is made of a porous medium, and a microcapsule structure is provided in the porous medium. The microcapsule structure contains a prefabricated liquid, and the prefabricated liquid contains water or alcohol. During the heating operation of the heating element, the microcapsule structure ruptures and releases the prefabricated liquid.

[0053] In this embodiment, the adsorption element is made of a porous medium, and microcapsule structures are evenly distributed inside the porous medium. These microcapsule structures encapsulate prefabricated liquid, which contains water or alcohol, or a mixture of the two. In some embodiments, the preparation of the microcapsule structure can be carried out by interfacial polymerization or spray drying, and the outer membrane material is selected from heat-sensitive materials such as gelatin, gum arabic or polylactic acid, which will undergo structural rupture at a specific temperature. The inner diameter of the microcapsule is usually controlled in the range of 50-200 μm, and the wall thickness is 1-5 μm, which can not only stably encapsulate the prefabricated liquid, but also ensure timely rupture during the heating process. At the same time, the distribution density of the microcapsules in the porous medium needs to be reasonably set, generally containing 1000-5000 microcapsules per cubic centimeter of porous medium, to ensure that the release amount of the prefabricated liquid can both assist in cleaning and not affect the adsorption performance of the adsorption element due to excessive amount. In some embodiments, when the heating element performs a heating operation, the heating temperature in the heating chamber gradually increases. When the heating temperature reaches the rupture temperature of the microcapsule shell (the rupture temperature is usually set at 60-80°C, which is lower than the heat resistance temperature of the adsorption element and the vaporization temperature of the residual substance), the microcapsule structure ruptures due to the softening or decomposition of the shell due to heat, and the prefabricated liquid encapsulated therein is released. In some embodiments, if the prefabricated liquid is water, it will evaporate rapidly in a high-temperature environment to form water vapor after release. The water vapor mixes with the volatile substances in the residual substance, which can reduce the surface tension of residual substances such as oil stains, making the residual substances easier to separate from the inner wall of the heating chamber. At the same time, the water vapor can moisten the porous structure of the adsorption element, thereby enhancing the capillary phenomenon's adsorption capacity for the liquefied residual substance.

[0054] In some other embodiments, if the prefabricated liquid is alcohol, which has good volatility and solubility, it will evaporate quickly after release and dissolve with residual substances such as oil stains, reducing the viscosity of the residual substances, promoting their conversion from solid or colloidal state to liquid or gaseous state, and accelerating the migration speed of the residual substances toward the adsorption element; in addition, the volatility of alcohol can also take away some heat, avoiding excessive local temperature in the heating chamber. In some embodiments, the timing of the microcapsule rupture matches the temperature progression of the heating operation. When the heating element begins to heat the residual material and before the residual material has largely evaporated, the microcapsules rupture to release the preformed liquid. This allows the preformed liquid to fully interact with the residual material and function, creating favorable conditions for subsequent vaporization and adsorption. Furthermore, because the microcapsules rupture only during heating, the preformed liquid does not leak when not in use, ensuring the storage stability and service life of the adsorption element. In the embodiment of the present application, the prefabricated liquid released by the microcapsules enhances the cleaning effect of residual substances, especially for stubborn oil stains accumulated over a long period of time, and can significantly improve the thoroughness of cleaning. It forms a synergistic effect with the porous structure and heating control logic of the adsorption element to further optimize the cleaning performance of the aerosol generating device.

[0055] In a possible implementation, the porous medium is at least one of a cotton fiber material, a cotton fiber material loaded with activated carbon particles, and a porous ceramic material.

[0056] In this embodiment, the porous medium used in the adsorption element can be selected from at least one of cotton fiber material, cotton fiber material loaded with activated carbon particles, and porous ceramic material. Different materials are adapted to different cleaning scene requirements through their respective structural characteristics and adsorption properties. In some embodiments, the porous medium is made of cotton fiber, which has a naturally porous structure and fine gaps between fibers. This allows for efficient adsorption of liquefied or vaporized residual matter through capillary action. Cotton is soft and adheres well to the inner walls of the heating chamber, reducing air leakage. It is also low-cost and suitable for daily replacement consumables. Furthermore, the cotton fiber must have a temperature resistance of >180°C to ensure it does not carbonize or degrade within the predetermined heating temperature range (e.g., 120-150°C). In some embodiments, when the porous medium is a cotton fiber material loaded with activated carbon particles, the activated carbon particles are attached to the fiber surface or interstices through impregnation, spraying, or other methods. The activated carbon particles have an extremely high specific surface area and rich microporous structure, significantly enhancing their ability to adsorb gaseous oil molecules. The chemical adsorption properties of activated carbon can effectively reduce the residual odor of long-term accumulated oil stains, making it suitable for use in applications requiring high cleanliness. In some embodiments, when porous ceramic materials are used as the porous medium, due to their rigid structure and uniform pore distribution, the porosity can be precisely controlled through the firing process, typically between 30% and 60%. The interconnected pores form a three-dimensional network, which not only absorbs liquid oils through capillary action but also provides ample diffusion channels for gaseous oils. Porous ceramics have excellent temperature resistance, exceeding 180°C, and maintain structural stability even at high temperatures in cleaning mode. Their smooth surface resists residual oil, making them easy to clean or reuse, making them suitable for applications requiring durability. In practical applications, aerosol-generating devices can be selected from a single material or a composite material, depending on their intended purpose. For example, entry-level devices can use pure cotton fiber to control costs; mid- to high-end devices can use cotton fiber loaded with activated carbon particles, balancing adsorption efficiency and cost; and professional-grade devices can use porous ceramic materials to meet the needs of long-term, high-frequency use.

[0057] In a possible implementation, the controller is further configured to execute: During the process of controlling the heating element to perform a heating operation on the residual material inside the heating chamber, in response to the received heating stop instruction, the heating element is controlled to stop the heating operation.

[0058] While controlling the heating element to heat the residual material inside the heating chamber, the controller also has the function of responding to a stop heating instruction and controlling the heating element to stop working, so as to cope with emergencies during the cleaning process and improve the safety and flexibility of users in using the aerosol generating device. In some embodiments, there may be multiple ways to trigger the stop heating instruction. It can be achieved through a physical button set on the shell of the aerosol generating device, such as pressing and holding the physical button corresponding to the cleaning mode for more than 2 seconds. After the controller receives a continuous electrical signal, it determines it as a stop heating instruction; it can also be triggered by a touch button on the display screen. When the user clicks the "Stop Cleaning" touch button during the cleaning process, the display screen converts the operation into an electrical signal and transmits it to the controller; in addition, if the aerosol generating device supports remote control, the stop instruction can also be sent through the corresponding mobile application, which is received by the wireless module and then transmitted to the controller. During the heating process, the controller monitors in real time whether it has received a stop heating command. Upon receiving this command, the heating element is immediately powered off and stopped, regardless of whether the current heating temperature has reached the predetermined range or the heating duration has met the predetermined time limit. The controller also records current heating status parameters, such as elapsed heating time and maximum temperature, so that when the user subsequently restarts the cleaning mode, they can choose to continue the remaining process or restart according to their needs. For example, if the user discovers that the adsorption element is improperly installed, or that the aerosol generating device makes unusual sounds or experiences abnormal temperatures, they can trigger a stop heating command to promptly terminate the heating process, preventing the fault from escalating. Alternatively, if the user needs to use the aerosol generating device temporarily, they can quickly stop the cleaning operation and switch to normal use mode. After heating stops, the prompt unit can output a corresponding prompt message, such as displaying "Heating Stopped" or the indicator light on the physical button turning solid orange, to inform the user of the current status. Through the above embodiments, while ensuring cleaning efficiency, the user is given active control over the cleaning process, further improving the safety and operational convenience of the aerosol generating device, and making the cleaning process more flexible and controllable.

[0059] In a possible implementation, the controller is further configured to execute: Record the number of times the adsorption element is used or the cumulative cleaning time; When the number of uses reaches a predetermined number or the cumulative cleaning time exceeds a predetermined time, the control prompt unit outputs a second prompt message, wherein the second prompt message is used to instruct the user to replace the adsorption element.

[0060] In this embodiment, in addition to executing the aforementioned control logic, the controller is also configured to have the function of recording the usage status of the adsorption element and triggering a replacement reminder. This function works in conjunction with the reminder unit to form a full life cycle management of the adsorption element. In some embodiments, a storage module is provided inside the controller for recording in real time the number of times the adsorption element is used and the cumulative cleaning time of each cleaning process. The number of uses refers to the complete cycle count from the time the adsorption element is placed in the heating chamber to the time the cleaning process is completed and taken out. The cumulative cleaning time is the sum of the actual working time of the heating element during each cleaning process. The triggering mechanism of the record is associated with the start and end of the cleaning process: when the infrared sensor detects that the adsorption element is placed in the heating chamber and the cleaning mode is started, the controller starts timing and marks the start of a usage record; when the cleaning process is completed (the heating element stops working and the prompt unit outputs the first prompt message), the controller adds the cleaning time to the cumulative time, and adds 1 to the number of uses, and stores these data in a non-volatile memory, which will not be lost even if the aerosol generating device is powered off. In some embodiments, the controller has preset threshold parameters for determining whether the adsorption element needs to be replaced, including a predetermined number of times (typically set to 5-10 times, which can be determined based on the material and capacity of the adsorption element, such as 5 times for cotton fiber materials and 10 times for porous ceramic materials) and a predetermined duration (typically set to 30-60 minutes, such as 30 minutes for cotton fiber materials loaded with activated carbon and 60 minutes for porous ceramic materials). After each cleaning process, the controller automatically calls the data in the storage module, compares the actual number of uses with the predetermined number, and compares the cumulative cleaning time with the predetermined duration. In some embodiments, when the controller detects that the adsorption element has been used a predetermined number of times (e.g., a cotton adsorption element has been used five times) or the cumulative cleaning time has exceeded a predetermined time (e.g., a porous ceramic adsorption element has been cleaned for 60 minutes), it determines that the adsorption element is nearing or has reached adsorption saturation, and that continued use may result in a decrease in cleaning effectiveness. At this point, the controller sends a control signal to the prompt unit, instructing it to output a second prompt message specifically instructing the user to replace the adsorption element. In some embodiments, the presentation form of the second prompt message can be distinguished from the first prompt message to avoid user confusion: if the prompt unit is a display screen, it can display a text message of "The adsorption element has reached its service life, please replace it", accompanied by a flashing prompt of the adsorption element icon and the word "replace"; if it is an LED indicator light, the green indicator light can be controlled to flash continuously at a frequency of twice per second; if it is a buzzer, it can emit a long beep prompt different from the first prompt message (such as a "beep" sound lasting 1 second, repeated 3 times after an interval of 1 second); if the aerosol generating device has a vibration function, two consecutive short vibrations (0.5 seconds each, with an interval of 0.5 seconds) can be used as a tactile prompt. In some embodiments, the function of instructing the user to replace the adsorption element can be adapted to the material properties of the adsorption element. For example, for cotton fiber materials with limited adsorption capacity, the replacement time can be controlled by the number of uses to avoid oil residue due to adsorption saturation. For porous ceramic materials that are reusable but whose adsorption performance decreases after long-term use, the replacement time can be controlled by the accumulated cleaning time to ensure that the adsorption element always maintains efficient adsorption capacity. At the same time, the usage data recorded by the controller will automatically reset after the adsorption element is removed and replaced with a new one. The new number of uses and accumulated cleaning time will be calculated from zero, forming a circular management system. Through the coordinated work of the controller and the prompt unit, intelligent monitoring of the adsorption element status is achieved, eliminating the need for users to manually record usage. This ensures the stability of the cleaning effect and avoids affecting equipment performance due to excessive use of the adsorption element, further improving the usability and maintenance convenience of the aerosol generating equipment and making the operation of the entire cleaning system more reliable.

[0061] The present application provides an embodiment of a method for controlling an aerosol generating device. Figure 4 As shown, Figure 4 The following is a schematic flow chart of a control method for an aerosol generating device provided by the present application. As an example and not a limitation, the method can be applied to or run in an aerosol generating device. The method includes: S401, when a cleaning instruction is received, controlling the heating element to perform a heating operation on the residual material inside the heating chamber, wherein the heating temperature of the heating operation is greater than the melting point temperature of the residual material and less than the temperature resistance temperature of the adsorption element.

[0062] S402 , when the heating temperature of the heating operation reaches a predetermined temperature range and the heating time reaches a predetermined time, controlling the heating element to stop the heating operation.

[0063] In some embodiments, the control method for an aerosol-generating device can be applied to or operated within the aerosol-generating device. The housing of the aerosol-generating device forms a mounting space for various components, providing structural support and protection for the device. A heating chamber is disposed within the housing. This chamber has a hollow cavity structure. The size and shape of the heating chamber are compatible with the aerosol substrate to be heated and the adsorption element subsequently used for cleaning, ensuring smooth placement and normal operation of the aerosol substrate and facilitating the insertion and removal of the adsorption element. In some embodiments, the heating element is disposed outside the heating chamber, and specifically may be a heating wire surrounding the periphery of the heating chamber, or a heating plate attached to the outer wall of the heating chamber.

[0064] In some embodiments, the heating element is connected to the controller via a wire and receives control signals from the controller to perform heating operations. The power of the heating element can be adjusted according to actual needs to meet the heating requirements of different substances within the heating chamber. It can be used to heat the aerosol substrate within the heating chamber to generate aerosols, and can also be used in cleaning mode to heat residual substances such as oil stains within the heating chamber to induce a state change in the residual substances.

[0065] In some embodiments, the adsorption element is placed inside the heating chamber in a detachable manner. The specific material can be a porous medium, such as cotton material or porous ceramic, and has good temperature resistance, for example, a temperature resistance greater than 180°C, to ensure that it will not be damaged by high temperature during the heating operation. The adsorption element can be in the shape of a columnar through hole or channel structure, and its size matches the cavity of the heating chamber, so it can be stably placed in the heating chamber. When the heating element heats the residual material inside the heating chamber, the volatile substances formed by the volatilization of the residual material after heating move toward the adsorption element, and the adsorption element can effectively adsorb these volatile substances by virtue of the capillary phenomenon generated by the porous structure, thereby achieving the purpose of cleaning the heating chamber. In some embodiments, the controller can be a microprocessor or single-chip microcomputer, located in a suitable location within the housing and connected to the heating element and other related control components via wires. The controller is pre-programmed with corresponding control programs and parameters to achieve precise control of the heating operation. When the controller receives a cleaning instruction, it can control the heating element to start heating the residual material inside the heating chamber. Optionally, the cleaning instruction can be triggered in a variety of ways, such as the user operating a physical button on the device, or sending an instruction through the touch screen on the device. During the heating process, the controller can strictly control the heating temperature to ensure that the heating temperature is greater than the melting point of the residual material. Only in this way can the residual material be transformed from a solid or semi-solid state to a liquid or gaseous state after heating, facilitating subsequent adsorption; at the same time, the heating temperature must be lower than the temperature resistance of the adsorption element to avoid damage to the adsorption element due to excessive temperature. The controller also has a preset temperature range and a preset duration. These two parameters were determined through multiple experiments based on the characteristics of the residual material and the performance of the adsorption element. When the heating temperature reaches the preset temperature range and the heating time reaches the preset duration, the controller determines that the residual material has fully evaporated and is adsorbed by the adsorption element. It then issues a command to the heating element to stop heating, completing the cleaning process. For example, after a cleaning device has been used for a period of time, a certain amount of oil residue (the residual substance is oil) accumulates inside the heating chamber. When the user wants to clean the residual oil, they place the adsorption element into the heating chamber and then send a cleaning command to the controller by operating the cleaning button on the device. After receiving the cleaning command, the controller controls the heating element to begin heating. When the heating temperature reaches a predetermined temperature range, such as 120-150°C, and the heating time reaches a predetermined time, such as 8-12 minutes, the controller determines that the residual substance has fully volatilized and is adsorbed by the adsorption element. At this time, the controller controls the heating element to stop heating. At this point, the volatile substances in the oil have been adsorbed by the adsorption element. The user removes the adsorption element from the heating chamber, completing the cleaning of the heating chamber. Using the control method of the aerosol generating device provided in the embodiment of the present application, it is possible to effectively remove substances such as oil residues inside the heating chamber in the cleaning mode, thereby preventing the accumulation of residual substances from affecting the user experience and service life of the aerosol generating device.

[0066] For a possible implementation, please refer to Figure 5 As shown, Figure 5 A schematic flow chart of a method for controlling an aerosol generating device provided by the present application is shown, the method further comprising: S501, controlling the infrared sensor to send infrared light into the interior of the heating chamber and receive reflected light, wherein the infrared sensor is used to determine whether the interior of the heating chamber is an aerosol matrix or an adsorption element based on the reflected light.

[0067] The heating chamber contains one of the aerosol matrix and the adsorption element at the same time.

[0068] S502: When the infrared sensor determines that the interior of the heating chamber is an adsorption element, it is determined that a cleaning instruction has been received.

[0069] In some embodiments, the infrared sensor is located within the housing and outside the heating chamber. The installation position must ensure that it can stably transmit infrared light into the heating chamber and effectively receive reflected light from the interior of the heating chamber. For example, the infrared sensor can be embedded in the side wall of the housing corresponding to the edge of the heating chamber opening, so that the direction of infrared light emission is at a certain angle to the axis of the heating chamber, thereby covering the main storage space within the heating chamber and ensuring accurate recognition of objects placed in the heating chamber. It should be understood that in the embodiments of this application, the core function of the infrared sensor is to distinguish whether the aerosol matrix or the adsorption element is placed inside the heating chamber. Due to the differences in the materials and structures of the aerosol matrix and the adsorption element, their reflection characteristics for infrared light are also different. By detecting changes in parameters such as the intensity and wavelength of the reflected light, the infrared sensor can accurately determine the type of object currently contained in the heating chamber. It should be noted that the heating chamber can only accommodate one of the aerosol matrix and the adsorption element at a time, so the infrared sensor's recognition result is unique. In some embodiments, the controller establishes a connection with the infrared sensor and receives identification signals transmitted by the infrared sensor in real time. When the infrared sensor determines that an adsorption element is placed within the heating chamber, it transmits this determination in the form of an electrical signal to the controller. Upon receiving this electrical signal, the controller immediately determines that a cleaning instruction has been received and automatically initiates cleaning mode without requiring additional manual operation by the user. In an optional embodiment, the specific working process is as follows: When the user places the adsorption element into the heating chamber, the infrared sensor emits infrared light. The light is reflected after hitting the surface of the adsorption element, and the reflected light is received by the infrared sensor. The infrared sensor analyzes the reflected light. Due to the porous structure and material properties of the adsorption element, the characteristics of the reflected light from the adsorption element are significantly different from those of the aerosol matrix. Based on this, the infrared sensor determines that there is an adsorption element in the heating chamber and feeds this determination result back to the controller. In response to this determination result, the controller directly triggers the cleaning process and controls the heating element to heat the residual material in the heating chamber according to the preset heating parameters. The subsequent heating temperature control, heating stop judgment, and other processes are consistent with the aforementioned embodiment. Through the coordinated work of the infrared sensor and the controller, the aerosol generating device can automatically trigger the cleaning instruction, simplifying the user's operation steps. At the same time, it ensures that the cleaning mode is automatically started in the correct usage scenario, further improving the convenience and reliability of equipment cleaning, and effectively avoiding the accumulation of residual substances caused by the user forgetting to trigger the cleaning instruction.

[0070] 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.
