Description

Heating control methods and aerosol generation equipment

[0001] Priority information

[0002] This disclosure claims priority and benefits to patent application No. 202410955988.0, filed with the China National Intellectual Property Administration on July 16, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of aerosol generation equipment technology, specifically to a temperature control method and an aerosol generation device. Background Technology

[0004] Currently, in related technologies, heated tobacco products can heat and atomize smoke using laser heating technology. Laser radiation heating eliminates the need for the heating element to contact the cigarette, and the laser power response is fast, heating the cigarette to nearly 350°C in a very short time (milliseconds), allowing for immediate stopping after use. However, most heated tobacco products in these technologies cannot monitor the cigarette's position in real time, thus lacking an automatic heating function, which negatively impacts user experience. Summary of the Invention

[0005] This application provides a heating control method and an aerosol generating device.

[0006] The heating control method disclosed in this application is used in an aerosol generating device. The aerosol generating device includes a support assembly, a first laser, and a second laser. The support assembly is used to mount the aerosol-generated product, and the light-emitting sides of the first and second lasers face the support assembly. The heating control method includes the following steps:

[0007] In the first mode, the first laser is controlled to intermittently emit detection lasers;

[0008] Acquire the detection feedback signal sent by the second laser, wherein the detection feedback signal is generated and determined by the second laser being irradiated by the reflected light of the detection laser;

[0009] The detection feedback signal is used to determine whether the aerosol-generated product is installed on the support assembly.

[0010] Within a first preset time period, based on the detection feedback signal, the state of the aerosol generating product not installed in the support assembly is switched to the state of being installed in the support assembly. The aerosol generating device is then controlled to enter a second mode. In the second mode, the first laser and / or the second laser are configured to generate a heating laser to heat the aerosol generating product.

[0011] Thus, when the aerosol generating equipment is started and enters the identification mode, this application divides multiple sets of lasers into two uses: detecting laser emission and receiving reflected light. The photoelectric signal generated by the laser that receives reflected light in the photoelectric effect is used to determine whether the aerosol generating product is in place. Furthermore, when the aerosol generating product is in place, the aerosol generating equipment is controlled to enter the normal working state and feedback is given to the user on the current working status of the aerosol generating device. This enables the aerosol generating equipment to automatically heat up when the aerosol generating product is inserted into the correct position on the aerosol generating equipment, without requiring additional user operation, thus improving the system's operational convenience and safety.

[0012] In some implementations, controlling the first laser to intermittently emit detection lasers in the first mode includes:

[0013] In response to detecting at least one of a first button signal, a first motion sensor signal, and a first gas flow sensor signal, or detecting that the circuit power is on, the aerosol generating device is powered on; and / or

[0014] In response to detecting at least one of a second button signal, a second motion sensor signal, and a second gas flow sensor signal, or detecting that the circuit power is on, the aerosol generating device is controlled to enter the first mode, wherein the first gas flow sensor and the second gas flow sensor are used to determine that the user is performing a suction action; and / or

[0015] In response to the aerosol generating device being powered on and entering a first mode, the first laser is controlled to periodically emit the detection laser, wherein the pulse duration of the detection laser is less than a preset pulse duration threshold, and the pulse power of the detection laser is within a preset power range.

[0016] Thus, this application can control the power-on of the aerosol generating device and the entry into the recognition mode based on signal parameters such as button input, the device's own motion state, the gas flow at the microphone on the device, and the power supply connection. Furthermore, once the aerosol generating device has entered the recognition mode, it can periodically control the laser used for detection laser emission to periodically emit detection lasers, thereby achieving periodic detection of aerosol-generated products and providing a logical basis for the automatic heating of the device when the aerosol-generated products are inserted into the aerosol generating device.

[0017] In some embodiments, determining whether the aerosol-generating article is installed on the support assembly based on the detection feedback signal includes:

[0018] If the detection feedback signal is within the first interval, it is determined that the aerosol-generating article is installed on the support assembly;

[0019] If the detection feedback signal is within the second interval, it is determined that the aerosol generating article is not installed on the support assembly, and the ranges of the first interval and the second interval do not overlap.

[0020] Thus, this application can also determine whether the aerosol-generated article is correctly installed on the support assembly based on the range of photoelectric signals generated by the laser used as a reflective light receiver.

[0021] In some embodiments, the method further includes:

[0022] In the first mode, or when it is determined that the aerosol-generating article is not installed on the support assembly, the energy of the laser output by the first laser and the second laser is limited;

[0023] If it is determined that the aerosol-generated article is not installed on the support assembly, the standby time of the aerosol-generating device is extended, and the aerosol-generating device is controlled to maintain the first mode in order to control the first laser to emit the detection laser.

[0024] Thus, this application can limit the maximum energy of the laser that each laser can output when the aerosol generating article is not correctly installed on the support assembly, so as to avoid the combustion or other accidents caused by excessive laser energy on other objects outside the support assembly or equipment due to high temperature. At the same time, it can also extend the standby time of the device and keep the device in the recognition mode, so as to facilitate the user to insert the aerosol generating article at any time to start using the device, thereby improving the convenience of use.

[0025] In some embodiments, the method further includes:

[0026] When the aerosol generating device is in the second mode, in response to detecting at least one of a third button signal or a third gas flow sensor signal, the first laser and / or the second laser are driven to emit heating lasers to heat the aerosol-generated article.

[0027] Thus, this application can generate aerosols by detecting user button presses or by the user making a suction action at the microphone when the aerosol generating equipment is in normal working condition, thereby triggering heating of the aerosol generating product.

[0028] In some embodiments, the method further includes:

[0029] When the aerosol generating device is in the second mode, in response to detecting at least one of a third button signal or a third gas flow sensor signal, the first laser is controlled to emit a detection laser.

[0030] Obtain the detection feedback signal sent by the second laser;

[0031] The detection feedback signal is used to determine whether the aerosol-generated product is installed on the support assembly.

[0032] If it is determined that the aerosol-generated article is installed on the support assembly and maintained for at least a second preset time, the first laser and / or the second laser are driven to emit heating lasers to heat the aerosol-generated article.

[0033] Thus, this application can also reconfirm whether the aerosol generating product has been correctly installed before the heating of the aerosol generating product is triggered by the user pressing a button or by the user making a suction action at the microphone when the aerosol generating equipment is in normal working condition, so as to ensure the reliability and safety of the heating process.

[0034] In some embodiments, the method further includes:

[0035] In response to a fourth gas flow sensor signal or a runtime signal, the first laser and / or the second laser are controlled to stop emitting heating lasers to stop heating the aerosol-generating article, wherein the fourth gas flow sensor signal is used to determine that the user's suction action has stopped.

[0036] Thus, this application can also stop the heating process in a timely manner by detecting whether the user stops the suction action or by detecting the heating time during the heating of the aerosol product in the aerosol generating device, thereby avoiding overheating of the aerosol product and the generated aerosol.

[0037] In some embodiments, the method further includes:

[0038] In response to the aerosol generating device entering the second mode, a preset prompt message is sent to the user, the preset prompt message being configured to prompt the user that the aerosol generating device has entered the second mode.

[0039] Thus, this application can also provide feedback to the user to remind them that the aerosol generating device has entered the start-up mode normally.

[0040] A heating control method is provided in this application for an aerosol generating device. The aerosol generating device includes a support assembly, a first laser, and a second laser. The support assembly is used to mount the aerosol generating product. The light-emitting sides of the first laser and the second laser face the support assembly. The heating control method includes:

[0041] In the second mode, the first laser is controlled to intermittently emit detection lasers;

[0042] Acquire the detection feedback signal sent by the second laser, wherein the detection feedback signal is generated and determined by the second laser being irradiated by the reflected light of the detection laser;

[0043] The detection feedback signal is used to determine whether the aerosol-generated product is installed on the support assembly.

[0044] Within a second preset time period, based on the detection feedback signal, the aerosol generating product is determined to switch from a state installed in the support assembly to a state not installed in the support assembly. The aerosol generating device is then controlled to enter a first mode. In the first mode, the first laser and / or the second laser are configured to identify whether the aerosol generating product is installed in the support assembly. In the first mode, the energy of the laser output by the first laser and the second laser is limited.

[0045] Thus, this application enables multiple lasers to be used for both detecting laser emission and receiving reflected light when the aerosol generating equipment is in normal working mode. The photoelectric signal generated by the laser that receives reflected light in the photoelectric effect is used to determine whether the aerosol generating product is in place. Furthermore, when the aerosol generating product is removed, the aerosol generating equipment is controlled to re-enter the recognition state, thereby automatically stopping the aerosol generating equipment when the aerosol generating product is removed from the aerosol generating equipment, without requiring additional user operation, thus improving the system's operational convenience and safety.

[0046] The aerosol generating device according to this application includes a support assembly, a controller, a first laser, and a second laser. The support assembly is used to mount the aerosol generating product, and the light-emitting sides of the first laser and the second laser face the support assembly. The controller is configured to:

[0047] In the first mode, the first laser is controlled to intermittently emit detection lasers;

[0048] Acquire the detection feedback signal sent by the second laser, wherein the detection feedback signal is generated and determined by the second laser being irradiated by the reflected light of the detection laser;

[0049] The detection feedback signal is used to determine whether the aerosol-generated product is installed on the support assembly.

[0050] Within a first preset time period, based on the detection feedback signal, the state of the aerosol generating product not installed in the support assembly is switched to the state of being installed in the support assembly, and the aerosol generating device is controlled to enter a second mode. In the second mode, the first laser and / or the second laser are configured to generate a heating laser to heat the aerosol generating product.

[0051] and / or

[0052] In the second mode, the first laser is controlled to intermittently emit detection lasers;

[0053] Acquire the detection feedback signal sent by the second laser, wherein the detection feedback signal is generated and determined by the second laser being irradiated by the reflected light of the detection laser;

[0054] The detection feedback signal is used to determine whether the aerosol-generated product is installed on the support assembly.

[0055] Within a third preset time period, based on the detection feedback signal, the aerosol generating product is determined to switch from a state installed in the support assembly to a state not installed in the support assembly. The aerosol generating device is then controlled to enter a first mode. In the first mode, the first laser and / or the second laser are configured to identify whether the aerosol generating product is installed in the support assembly. In the first mode, the energy of the laser output by the first laser and the second laser is limited.

[0075] The aerosol generating device 100 provided in this application embodiment is used to heat an aerosol generating matrix to generate aerosols for user use. The heating method can be convection, conduction, radiation, or a combination thereof. The aerosol generating matrix can be in the form of a liquid, gel, paste, or solid. When the aerosol generating matrix is ​​solid, it can be in the form of pulverized, granulated, powdered, granular, strip-shaped, or flake-shaped solid. The aerosol generating matrix includes, but is not limited to, materials used for medical, health, and cosmetic purposes. For example, the aerosol generating matrix may be a liquid medicine, oil, or plant-based materials, such as plant roots, stems, leaves, flowers, buds, and seeds. That is, the embodiments of this application do not limit the heating method, form, or application of the aerosol generating matrix.

[0076] Referring to Figure 1, this application provides an aerosol generation device 100. The aerosol generation device 100 includes a support assembly 10, a first laser 21, a second laser 22, and a controller 30. The support assembly 10 is used to mount an aerosol generation article 200, which contains an aerosol generation matrix. The light-emitting sides of the first laser 21 and the second laser 22 face the support assembly 10; that is, the laser beam paths of the first laser 21 and the second laser 22 pass through the support assembly 10. The support assembly 10 includes a support base 11 and a support sidewall 12, with the support sidewall 12 connected to the support base 11. When the aerosol generation article 200 is installed in the aerosol generation device 100, the support base 11 provides support for the aerosol generation article 200. The support sidewall 12 can provide a certain degree of fixation for the aerosol generation article 200, preventing it from tilting. The support sidewall 12 can also block the laser, protecting other parts of the aerosol generation device 100 from laser irradiation. Furthermore, the support sidewall 12 includes two opposing sides, one of which is provided with a light-transmitting part 122, allowing the laser emitted by the first laser 21 and the second laser 22 to pass through the light-transmitting part 122 and enter the support assembly 10; the other side is provided with an irradiated position 121, whereby, when the aerosol generating article 200 is not installed in the aerosol generating device 100, the laser emitted by the first laser 21 and the second laser 22 will irradiate the irradiated position 121 through the light-transmitting part 122.

[0077] In this way, when the aerosol generating article 200 is installed on the support assembly 10, the lasers from the first laser 21 and the second laser 22 can irradiate the aerosol generating article 200, causing the aerosol generating matrix within the aerosol generating article 200 to absorb the laser energy and be heated to generate an inhalable aerosol. The controller 30 is configured to control the first laser 21 and / or the second laser 22 to emit lasers, for example, to control whether the first laser 21 and / or the second laser 22 emit lasers, the emitted laser power, the emitted laser frequency, the duration of continuous laser emission, etc., which are not limited here. The controller 30 can independently control either the first laser 21 or the second laser 22.

[0078] During the use of the aerosol generating device 100, in order to heat the aerosol generating matrix to a temperature that can generate aerosols, the first laser 21 and the second laser 22 need to emit high-energy lasers so that the aerosol generating matrix can absorb enough energy. The above-mentioned process of generating aerosols by laser is based on the premise that the aerosol generating product 200 is correctly installed on the support assembly 10. When its installation is incorrect, the above-mentioned heating process is generally not started.

[0079] Based on this, in order to enable the aerosol generating equipment 100 to automatically perform the heating process when the aerosol generating article 200 is correctly installed on the support assembly 10, this application provides the following heating control method.

[0080] Please refer to Figures 1 and 2. The heating control method in this embodiment of the application specifically includes the following steps:

[0081] 01: In the first mode, the first laser 21 is controlled to intermittently emit detection lasers;

[0082] 02: Obtain the detection feedback signal sent by the second laser 22.

[0083] The detection feedback signal is generated and determined by the reflected light from the detection laser irradiating the second laser 22;

[0084] 03: Determine whether the aerosol generating product 200 is installed on the support component 10 based on the detection feedback signal;

[0085] 04: Within a first preset time period, based on the detection feedback signal, if the state of the aerosol generating product 100 not installed in the support component 10 is determined to switch to the state of being installed in the support component 10, the aerosol generating device 100 is controlled to enter the second mode.

[0086] In the second mode, the first laser and / or the second laser are configured to generate a heating laser to heat the aerosol to form an article.

[0087] The controller 30 of the aerosol generating device 100 can be used to execute the heating control methods in steps 01, 02, 03, and 04 above. That is, the controller 30 can be used to: control the first laser 21 to emit a detection laser in the first mode; acquire the detection feedback signal sent by the second laser 22; determine whether the aerosol generating product 200 is installed on the support assembly 10 based on the detection feedback signal; and, if it is determined that the aerosol generating product 200 is installed on the support assembly 10, control the aerosol generating device 100 to enter the second mode.

[0088] The electronic device in this application embodiment can implement the above-described heating control method. Specifically, the electronic device includes a memory and a processor, wherein the memory stores a computer program, the processor is used to control the first laser 21 to emit a detection laser in a first mode, to acquire a detection feedback signal sent by the second laser, and to control the aerosol generating device 100 to enter a second mode when it is determined that the aerosol generating article 200 is installed on the support assembly 10.

[0089] Specifically, to achieve the above objectives, the embodiments of this application, when the aerosol generating device 100 is powered on and enters the recognition mode (corresponding to the first mode), divide each laser of the aerosol generating device 100 into two groups for different purposes. The first laser 21 forms one group, used to emit a detection laser, while the second laser 22 forms the other group, used to receive reflected light formed by the detection laser through the optical path of the first laser 21, the support component 10, and the second laser 22. When the second laser 22 receives the reflected light energy, due to the photoelectric effect, the unexcited second laser 22 will generate photoelectric signals such as photocurrent / photoelectromotive force (corresponding to the detection feedback signal). Please refer to Figures 3 and 4, which show the cases of the aerosol generating matrix being correctly installed and not installed, respectively. Based on the above diagram, it is common sense that the correct installation of the aerosol generating matrix will cause the surface and distance of the detection laser to differ between when the aerosol generating matrix is ​​not in the irradiated position and when it is in the irradiated position. This directly affects the optical path of the detection laser. Therefore, the correct installation of the aerosol generating matrix will directly change the reflected light received by the second laser 22, thus further affecting the photoelectric signal generated by the photoelectric effect. Therefore, the above photoelectric signal value can be used to determine whether the aerosol generating matrix is ​​correctly installed. When the controller 30 of the aerosol generating device 100 receives the above photoelectric signal, it determines whether the aerosol generating product 200 is installed on the support component 10 based on the properties of the photoelectric signal itself. If it is detected that it is correctly installed, on the one hand, it controls the aerosol generating device 100 to enter the normal working mode (corresponding to the second mode), and on the other hand, it can remind the user that the aerosol generating product 200 is correctly installed and the aerosol generating device 100 has entered the normal working mode through voice, screen pop-up, vibration, etc.

[0090] It is important to note that, to ensure the accuracy of mode switching control based on photoelectric signals, regardless of whether the controller 30 determines whether the aerosol generating product 200 is currently installed on the support assembly 10 based on the aforementioned photoelectric signals, if further mode switching control is to be performed based on the determination result, it is also necessary to detect the duration for which the determination result can be maintained. The change in the positional relationship between the aerosol generating product 200 and the support assembly 10 at the beginning and end of the aforementioned duration is used to determine whether the aerosol generating product 200 is installed on the support assembly 10, thereby reducing the probability of misidentification. For example, if it is detected that the aerosol generating product 200 is not fixedly connected to the support assembly 10 at the beginning of the first preset duration, but is fixedly connected to the support assembly 10 at the end of the first preset duration, it can be determined that the aerosol generating product 200 is correctly installed on the support assembly 10, and the controller 30 controls the aerosol generating device 100 to enter normal operating mode. The aforementioned first preset duration can be any value within the range of 0s to 3s.

[0091] Thus, when the aerosol generating device 100 is started and enters the recognition mode, this application divides multiple lasers into two uses: detecting laser emission and receiving reflected light. The photoelectric signal generated by the laser that receives reflected light in the photoelectric effect is used to determine whether the aerosol generating product 200 is in place. Furthermore, when the aerosol generating product 200 is in place, the aerosol generating device 100 is controlled to enter the normal working state. This enables the aerosol generating device 100 to automatically heat up when the aerosol generating product 200 is inserted into the correct position on the aerosol generating device 100, without requiring additional user operation, thus improving the system's operational convenience and safety.

[0092] Please refer to Figure 5. In some embodiments, step 01 includes:

[0093] 011: In response to detecting at least one of the first button signal, the first motion sensor signal, and the first gas flow sensor signal, or detecting that the circuit power supply 50 is turned on, control the aerosol generating device 100 to power on; and / or

[0094] 012: In response to detecting at least one of the second button signal, the second motion sensor signal, and the second gas flow sensor signal, or detecting that the circuit power supply 50 is turned on, the aerosol generating device 100 is controlled to enter the first mode.

[0095] The first gas flow sensor and the second gas flow sensor are used to determine whether the user is performing a suction action; and / or

[0096] 013: In response to the aerosol generating device 100 being powered on and entering the first mode, the first laser 21 is controlled to periodically emit detection lasers.

[0097] The detection laser pulse duration is less than a preset pulse duration threshold, and the detection laser pulse power is within a preset power range.

[0098] In some embodiments, the controller 30 of the aerosol generating device 100 can be used to perform steps 011, 012, and 013 described above. That is, the controller 30 can be used to: control the aerosol generating device 100 to power on in response to detecting at least one of a first button signal, a first motion sensor signal, and a first gas flow sensor signal, or detecting that the circuit power supply 50 is turned on; control the aerosol generating device 100 to enter a first mode in response to detecting at least one of a second button signal, a second motion sensor signal, and a second gas flow sensor signal, or detecting that the circuit power supply 50 is turned on; and control the first laser 21 to periodically emit detection lasers in response to the aerosol generating device 100 being powered on and entering the first mode.

[0099] In some embodiments, the processor is further configured to control the aerosol generating device 100 to start in response to detecting at least one of a first button signal, a first motion sensor signal, and a first gas flow sensor signal, or detecting that the circuit power is on; and to control the aerosol generating device 100 to enter a first mode in response to detecting at least one of a second button signal, a second motion sensor signal, and a second gas flow sensor signal, or detecting that the circuit power 50 is on; and to control the first laser 21 to periodically emit detection lasers in response to the aerosol generating device 100 being powered on and entering the first mode.

[0100] Specifically, regarding the power-on startup and entry into the recognition mode of the aerosol generating device 100, in some examples, the aerosol generating device 100 is also equipped with a button component. When the user presses the button in a preset manner, such as short press, long press, or multiple consecutive presses (method A), the controller 30 receives a first button signal from the button component. At this time, the controller 30 controls the aerosol generating device 100 to power on based on the first button signal. Furthermore, the controller 30 can further control the aerosol generating device 100 to enter the recognition mode based on the first button signal. In other examples, after the aerosol generating device 100 is powered on, when the user presses the button in a preset manner, such as short press, long press, or multiple consecutive presses (method B), the controller 30 receives a second button signal from the button component. At this time, the controller 30 controls the aerosol generating device 100 to enter the recognition mode based on the second button signal.

[0101] In other examples, the aerosol generating device 100 is equipped with a motion sensor to detect its current spatial motion. If the motion sensor detects that the aerosol generating device 100's position has been raised to a height within a preset range within a short period, it can be assumed that the user has taken the aerosol generating device 100 from their pocket or other location to their mouth. At this point, the motion sensor generates a first motion sensor signal and sends it to the controller 30. Upon receiving the first motion sensor signal, the controller 30 powers on the aerosol generating device 100. Furthermore, the controller 30 can further control the aerosol generating device 100 to enter a recognition mode based on the first motion sensor signal. In addition, in other examples, after the aerosol generating device 100 is powered on, if the motion sensor detects that the aerosol generating device 100 has maintained its current position for a short period, the motion sensor generates a second motion sensor signal and sends it to the controller 30. Upon receiving the second motion sensor signal, the controller 30 controls the aerosol generating device 100 to enter a recognition mode.

[0102] In some examples, the aerosol generating device 100 is also equipped with a microphone, through which the user can perform a suction action to inhale the aerosol. A gas flow sensor is also installed at the microphone, which measures physical quantities such as the flow rate and pressure of the gas inside the microphone and converts them into electrical signals. When the gas flow sensor detects an increase in flow rate or a decrease in pressure inside the microphone, it can be considered that the user has performed a suction action. At this time, the gas flow sensor generates a first gas flow sensor signal and sends it to the controller 30. After receiving the first gas flow sensor signal, the controller 30 controls the aerosol generating device 100 to power on. Based on this, the controller 30 can further control the aerosol generating device 100 to enter a recognition mode based on the first gas flow sensor signal. Furthermore, in some examples, after the aerosol generating device 100 is powered on, when the gas flow sensor detects another change in flow rate or pressure inside the microphone, it can be considered that the user has performed or stopped the suction action. At this time, the gas flow sensor generates a second gas flow sensor signal and sends it to the controller 30. After receiving the signal from the second gas flow sensor, the controller 30 controls the aerosol generating device 100 to enter the recognition mode.

[0103] In some other examples, referring to Figure 1, the power supply 50 of the aerosol generating device 100 is a dry cell battery or a rechargeable battery. When the power supply 50 is connected to the circuit, the controller 30 detects that the overall circuit of the aerosol generating device 100 is connected, and at this time, the controller 30 controls the aerosol generating device 100 to power on. Based on this, the controller 30 can further control the aerosol generating device 100 to enter the recognition mode.

[0104] After the aerosol generating device 100 enters the recognition mode, it controls the first laser 21 to emit a detection laser, thus initiating the detection process to determine whether the aerosol generated product 200 is correctly installed on the support component 10.

[0105] Based on the above implementation, in order to enable the aerosol generating device 100 to automatically heat up when the aerosol generating product 200 is correctly installed, it is necessary to continuously detect whether the aerosol generating product 200 is correctly installed. This ensures that the controller 30 can promptly control the aerosol generating device 100 to enter normal operating mode when the aerosol generating product 200 is correctly installed. Therefore, in some examples, after the aerosol generating device 100 enters the recognition mode, the controller 30 will control the first laser 21 to periodically emit detection lasers, thereby ensuring that the correct installation of the aerosol generating product 200 can be detected at any time. This fundamentally guarantees the logical basis for the aerosol generating device 100 to automatically enter normal operating state when the aerosol generating product 200 is inserted into the aerosol generating device 100. In addition, to save system energy consumption, the pulse duration and pulse power of the detection laser generally also need to be controlled. In some examples, a preset threshold is generally set for the pulse duration, which is generally in the range of 10μs to 1ms. The specific value can be adjusted according to the actual situation. The pulse power is generally controlled in the range of 1W to 15W.

[0106] For example, referring to Figure 6, in some examples, the aforementioned photoelectric signal is a feedback voltage. The time period during which the first laser 21 emits the detection laser is the total time period from the start of the detection laser emission to the reflection of the detected laser to the second laser 22 to generate a feedback voltage, until the generated feedback voltage disappears. This ensures that after one detection laser emission, the second laser 22 can respond to the reflected light of that emitted detection laser and generate a feedback voltage. For example, the first laser 21 emits a detection laser every time interval T1. The total time period during which the feedback voltage exists in the t1 time period of Figure 5 (the time from the start of the detection laser emission to the second laser 22 receiving the reflected detection laser is very short and negligible) is taken as the time period during which the first laser 21 emits the detection laser.

[0107] It should be noted that the order of steps 011, 012, and 013 in Figure 5 is only for illustrative purposes. In actual execution, the order of the three steps can be adjusted according to the actual situation. Figure 5 should not be interpreted as a limitation on the execution order.

[0108] Thus, this application can control the power-on of the aerosol generating device 100 and the entry into the recognition mode based on signal parameters such as button input, the device's own motion state, the gas flow at the microphone on the device, and the power supply 50 connection status. Furthermore, based on the aerosol generating device 100 entering the recognition mode, it can periodically control the laser used for detection laser emission to periodically emit detection lasers, thereby realizing the periodic detection of the aerosol generating product 200 and providing a logical basis for the automatic heating of the device when the aerosol generating product 200 is inserted into the aerosol generating device 100.

[0109] Please refer to Figure 7. In some embodiments, step 03 includes:

[0110] 031: If the detection feedback signal is within the first interval, it is determined that the aerosol generating product 200 is installed on the support assembly 10;

[0111] 032: If the detection feedback signal is within the second interval, it is determined that the aerosol generating product 200 is not installed on the support assembly 10, and the ranges of the first and second intervals do not overlap.

[0112] In some embodiments, the controller 30 of the aerosol generating device 100 can be used to perform steps 031 and 032 described above. That is, the controller 30 can be used to: determine that the aerosol generating article 200 is installed on the support assembly 10 when the detection feedback signal is within the first interval; and determine that the aerosol generating article 200 is not installed on the support assembly 10 when the detection feedback signal is within the second interval, and the ranges of the first interval and the second interval do not overlap.

[0113] In some embodiments, the processor is further configured to determine, if the detection feedback signal is within a first interval, that the aerosol generating article 200 is mounted on the support assembly 10, and to determine, if the detection feedback signal is within a second interval, that the aerosol generating article 200 is not mounted on the support assembly 10, wherein the ranges of the first and second intervals do not overlap.

[0114] Specifically, please refer to Figure 6 again. It should be noted beforehand that in some examples, the second laser 22 generates a photogenerated electromotive force (EMF) when irradiated by the reflected detection laser. The controller 30 can detect the photogenerated EMF generated by the second laser 22 to obtain a feedback voltage, which is used as the detection feedback signal. In other examples, a feedback current can also be obtained based on the photogenerated EMF generated by the second laser 22, and the feedback current can be used as the detection feedback signal. This is not a limitation here.

[0115] Taking the feedback signal as a feedback voltage as an example, the first interval refers to the first voltage interval, corresponding to the interval (Vth1, Vth2) shown in Figure 6, and the second interval refers to the second voltage interval, corresponding to the interval (Vth3, Vth4) shown in Figure 6. The feedback voltage value generated by the second laser 22 differs depending on whether the aerosol generating product 200 is installed in the aerosol generating device 100 or not. Therefore, it is possible to determine whether the detection laser irradiates the aerosol generating product 200 based on the feedback voltage generated by the second laser 22, thereby determining whether the aerosol generating product 200 is installed on the support assembly 10.

[0116] As shown in Figure 6, the first interval is the pre-determined voltage range that can be detected by the second laser 22 when the detection laser irradiates the aerosol generating article 200 and reflects back to the second laser 22. If the aerosol generating article 200 is mounted on the support assembly 10, when the first laser 21 emits the detection laser, the feedback voltage of the second laser 22 after irradiating the aerosol generating article 200 and reflecting back to the second laser 22 should be within the first interval. Therefore, when the feedback voltage is within the first interval, it can be determined that the aerosol generating article 200 is mounted on the support assembly 10.

[0117] Similarly, the second interval is the pre-determined voltage range that the second laser 22 can detect when the detection laser irradiates the irradiated position 121 of the support assembly 10 and reflects back to the second laser 22. If the aerosol generating article 200 is not installed on the support assembly 10, and the first laser 21 emits a detection laser, and the detection laser irradiates the irradiated position 121 and reflects back to the second laser 22, then the feedback voltage of the second laser 22 should be within the second interval. Therefore, if the second laser 22 generates a feedback voltage when the first laser 21 emits a detection laser, and the feedback voltage is not within the first interval but is within the second interval, it indicates that the detection laser irradiates not the aerosol generating article 200, but the irradiated position 121, thus confirming that the aerosol generating article 200 is not correctly installed on the support assembly 10.

[0118] As shown in Figure 6, if the feedback voltage is detected to jump from the first interval (Vth1, Vth2) to the second interval (Vth3, Vth4) during a certain period, that is, the aerosol generating product 200 changes from being installed in the support assembly 10 to not being installed in the support assembly 10, it means that the aerosol generating product 100 was pulled out of the support assembly 10 during the jump period. Conversely, if the feedback voltage is detected to jump from the second interval (Vth3, Vth4) to the first interval (Vth1, Vth2) during a certain period, that is, the aerosol generating product 200 changes from not being installed in the support assembly 10 to being installed in the support assembly 10, it means that the aerosol generating product 100 was correctly inserted into the support assembly 10 during the jump period.

[0119] In one embodiment, the insertion of the aerosol generating article 200 can be used as a heating start signal. For example, when the feedback voltage jumps from the second interval to the first interval, the feedback voltage signal of the first first interval (e.g., signal S1 in FIG. 6) can be used as a start signal to control the aerosol generating device 100 to enter the normal operation mode.

[0120] The first and second intervals do not overlap. To avoid a situation where the feedback voltage falls within both the first and second intervals, making it impossible to determine whether the detection laser is irradiating the aerosol generating product 200 or the irradiated position 121, the intensity of the reflected laser can be controlled by adjusting the shell material of the aerosol generating product 200, the material of the irradiated position 121, applying a coating, adjusting the distance between the irradiated position 121 and the first laser 21, and adjusting the power of the detection laser. This ensures that the first and second intervals do not overlap. As shown in Figure 6, for example, if the range of the first interval is (Vth1, Vth2) and the range of the second interval is (Vth3, Vth4), then simply setting Vth1 > Vth4 or Vth3 > Vth2 will ensure that the first and second intervals do not overlap.

[0121] Thus, this application can also determine whether the aerosol generating article 200 is correctly installed on the support assembly 10 based on the range of photoelectric signals generated by the laser used as a reflective light receiver.

[0122] In some embodiments, the heating control method further includes:

[0123] In the first mode, or when it is determined that the aerosol generating article 200 is not installed on the support assembly 10, the energy of the laser output by the first laser 21 and the second laser 22 is limited;

[0124] If it is determined that the aerosol generating article 200 is not installed on the support assembly 10, the standby time of the aerosol generating device 100 is extended, and the aerosol generating device 100 is controlled to maintain the first mode in order to control the first laser 21 to emit a detection laser.

[0125] In some embodiments, the controller 30 of the aerosol generating device 100 can be used to perform the above steps. That is, the controller 30 can be used to: limit the energy of the laser output from the first laser 21 and the second laser 22 when it is determined that the aerosol generating article 200 is not installed on the support assembly 10; extend the standby time of the aerosol generating device 100 when it is determined that the aerosol generating article 200 is not installed on the support assembly 10; and control the aerosol generating device 100 to maintain a first mode to control the first laser 21 to emit a detection laser.

[0126] In some embodiments, the processor is also configured to limit the energy of the laser output from the first laser 21 and the second laser 22 when it is determined that the aerosol generating article 200 is not installed on the support assembly 10, and to extend the standby time of the aerosol generating device 100 when it is determined that the aerosol generating article 200 is not installed on the support assembly 10, and to control the aerosol generating device 100 to maintain a first mode to control the first laser 21 to emit a detection laser.

[0127] Specifically, based on the above embodiments, when the aerosol generating device 100 is in identification mode, or when the controller 30 determines, based on the photoelectric signal generated by the second laser 22, that the aerosol generating product 200 is not correctly installed on the support assembly 10, the aerosol generating device 100 should not enter normal operation. For example, to ensure the safe use of the aerosol generating device 100, and to minimize the impact of the lasers emitted by the first laser 21 and the second laser 22 on the user or other objects around the device when the aerosol generating product 200 is not correctly installed on the support assembly 10, the controller 30 limits the maximum energy of the lasers output by the first laser 21 and the second laser 22. This reduces the probability of high-energy laser irradiation causing safety threats such as high temperatures or ignition to the user, the aerosol generating device 100, and the surrounding environment, thereby improving the safety of the aerosol generating device 100.

[0128] Furthermore, based on the above embodiments, when the controller 30 determines, based on the photoelectric signal generated by the second laser 22, that the aerosol-generating product 200 is not correctly installed on the support assembly 10, in order to further maintain the automatic heating operation logic of the aerosol generating device 100 in normal working mode based on whether the aerosol generating substrate is correctly installed, in some examples, the controller 30 will further extend the standby time of the aerosol generating device 100, thereby extending the standby power-on time of the aerosol generating device 100, thereby extending the time the aerosol generating device 100 is in the identification mode, thereby maintaining the automatic heating operation logic of the aerosol generating device 100 in normal working mode based on whether the aerosol generating substrate is correctly installed.

[0129] Thus, this application can limit the maximum energy of the laser that each laser can output when the aerosol generating article 200 is not properly installed on the support component 10, thereby preventing the support component 10 or other objects outside the equipment from burning or other accidents due to high temperature caused by excessive laser energy. At the same time, it can also extend the standby time of the device and keep the device in the recognition mode, so that users can insert the aerosol generating article at any time to start using the device, thus improving the convenience of use.

[0130] Referring to Figure 8, in some embodiments, the second laser 22 is a semiconductor laser, and the heating control method further includes:

[0131] 001: In response to the second laser 22 being irradiated by the reflected light of the detection laser in the unexcited state, an initial detection feedback signal is generated;

[0132] 002: Based on the initial detection feedback signal, the detection feedback signal is determined through preset electrical signal processing.

[0133] In some embodiments, the controller 30 of the aerosol generating device 100 can be used to perform the above steps. That is, the controller 30 can be used to: generate an initial detection feedback signal in response to the second laser 22 being irradiated by the reflected light of the detection laser in an unexcited state; and determine a detection feedback signal based on the initial detection feedback signal and after processing by a preset electrical signal.

[0134] In some embodiments, the processor is further configured to generate an initial detection feedback signal in response to the second laser 22 being irradiated by the reflected light of the detection laser in an unexcited state, and to determine the detection feedback signal based on the initial detection feedback signal and through preset electrical signal processing.

[0135] Specifically, based on the above embodiments, it is common knowledge that the intensity of photoelectric signals such as photocurrent or photoelectromotive force generated in the photoelectric effect produced by laser irradiation is generally weak, and the recognition accuracy requirements are relatively high when using the above photoelectric signals for direct identification. In order to reduce the difficulty of recognizing photoelectric signals, in some examples, after receiving the photoelectric signal generated by the second laser 22 (corresponding to the initial detection feedback signal), the controller 30 uses an amplification circuit or other electrical signal processing circuit set in itself to amplify or otherwise process the received photoelectric signal (corresponding to preset electrical signal processing), thereby processing the above-mentioned received photoelectric signal into a signal that can be directly identified (corresponding to the detection feedback signal), so that the aerosol generating product 200 can be correctly installed on the support component 10 by subsequently identifying the processed signal.

[0136] Thus, this application can also perform electrical signal processing on the photoelectric signal generated by the laser used as a receiver of reflected light based on the photoelectric effect, to obtain a detection feedback signal that can be directly used for range determination, thereby overcoming the problem that the photoelectric signal is too weak to make accurate determination.

[0137] In some embodiments, the heating control method further includes:

[0138] When the aerosol generating device 100 is in the second mode, in response to detecting at least one of the third button signal or the third gas flow sensor signal, the first laser 21 and / or the second laser 22 are driven to emit heating lasers to heat the aerosol generating article 200.

[0139] In some embodiments, the controller 30 of the aerosol generating apparatus 100 can be used to perform the above steps. That is, the controller 30 can be used to: drive the first laser 21 and / or the second laser 22 to emit heating lasers to heat the aerosol generating article 200 in response to detecting at least one of the third button signal or the third gas flow sensor signal when the aerosol generating apparatus 100 is in the second mode.

[0140] In some embodiments, the processor is also configured to, when the aerosol generating apparatus 100 is in a second mode, drive the first laser 21 and / or the second laser 22 to emit heating lasers to heat the aerosol generating article 200 in response to detecting at least one of a third button signal or a third gas flow sensor signal.

[0141] Specifically, based on the above implementation method, when the aerosol generating device 100 enters the normal working mode, in order to enable the user to inhale aerosol, in some examples, if the user presses the button in a preset button method C such as short press, long press, or multiple consecutive presses, the controller 30 will receive the third button signal sent by the button component. At this time, the controller 30 controls one or more of the first laser 21 and the second laser 22 in the aerosol generating device 100 to turn on the laser irradiation according to the third button signal, thereby realizing the heating of the aerosol generating product 200.

[0142] In other examples, if the gas flow sensor detects an increase in flow velocity or a decrease in pressure inside the microphone, it can be assumed that the user has performed a suction action. In this case, the gas flow sensor generates a third gas flow sensor signal and sends it to the controller 30. Upon receiving this third gas flow sensor signal, the controller 30 controls one or more of the first laser 21 and the second laser 22 in the aerosol generating device 100 to activate laser irradiation, thereby heating the aerosol-generated product 200.

[0143] When the aerosol generating matrix in the aerosol generating product 200 is heated by the laser irradiation described above, it can generate an aerosol that can be inhaled by the user.

[0144] Thus, this application can generate aerosols by detecting user button presses or by the user making a suction action at the microphone when the aerosol generating equipment is in normal working condition, thereby triggering heating of the aerosol generating product.

[0145] Please refer to Figure 9. In some embodiments, the heating control method further includes:

[0146] 0031: When the aerosol generating device 100 is in the second mode, in response to detecting at least one of the third button signal or the third gas flow sensor signal, the first laser 21 is controlled to emit a detection laser;

[0147] 0032: Acquire the detection feedback signal sent by the second laser 22;

[0148] 0033: Determine whether the aerosol generating product 200 is installed on the support component 10 based on the detection feedback signal;

[0149] 0034: When it is determined that the aerosol generating article 200 is installed on the support assembly 10 and maintained for at least the second preset time, the first laser 21 and / or the second laser 22 are driven to emit heating lasers to heat the aerosol generating article 200.

[0150] In some embodiments, the controller 30 of the aerosol generating device 100 can be used to perform the above steps 0031, 0032, 0033, and 0034. That is, the controller 30 can be used to: when the aerosol generating device 100 is in the second mode, in response to detecting at least one of a third button signal or a third gas flow sensor signal, control the first laser 21 to emit a detection laser; acquire the detection feedback signal sent by the second laser 22; determine whether the aerosol generating article 200 is installed on the support assembly 10 based on the detection feedback signal; and, if it is determined that the aerosol generating article 200 is installed on the support assembly 10 and maintained for at least a second preset time, drive the first laser 21 and / or the second laser 22 to emit a heating laser to heat the aerosol generating article 200.

[0151] In some embodiments, the processor is further configured to, when the aerosol generating device 100 is in the second mode, control the first laser 21 to emit a detection laser in response to detecting at least one of a third button signal or a third gas flow sensor signal, and to acquire a detection feedback signal sent by the second laser 22, and to determine whether the aerosol generating article 200 is mounted on the support assembly based on the detection feedback signal, and to drive the first laser 21 and / or the second laser 22 to emit a heating laser to heat the aerosol generating article 200 if it is determined that the aerosol generating article 200 is mounted on the support assembly 10 and maintained for at least a second preset duration.

[0152] Specifically, based on the above implementation method, when the aerosol generating device 100 enters the normal working mode, since the aerosol generating product 200 and the support component 10 are fixedly connected by plugging and unplugging, during use, it is possible that after the controller 30 controls the aerosol generating device 100 to enter the normal working mode, the position of the aerosol generating product 200 changes, causing the aerosol generating product 200 and the support component 10 to return to the state of not being installed correctly. If the laser is rashly controlled to heat at this time, it may lead to unpredictable consequences.

[0153] Therefore, for example, in order to ensure the safe use of the aerosol generating device 100, when the aerosol generating device 100 enters the normal working mode, in response to the user's button press or user suction action in the above embodiments, the controller first uses the method in the above embodiments to reconfirm whether the aerosol generating product 200 is correctly installed on the support component 10.

[0154] For example, if the aerosol generating product 200 is detected to be fixedly connected to the support component 10 at the start time of the second preset duration, and the aerosol generating product 200 is also detected to be fixedly connected to the support component 10 at the end time of the second preset duration, it can be determined that the aerosol generating product 200 and the support component 10 are correctly installed. The controller 30 controls the aerosol generating device 100 to enter the normal working mode. The second preset duration should generally be less than the first preset duration in the above embodiment to avoid negative impacts on the smooth use of the aerosol generating device 100.

[0155] When the controller 30 determines that the aerosol-generating product 200 has been correctly installed on the support assembly 10 in accordance with the above method, the controller 30 further controls one or more of the first laser 21 and the second laser 22 in the aerosol generating equipment 100 to turn on laser irradiation, thereby achieving heating of the aerosol-generating product 200.

[0156] When the aerosol generating matrix in the aerosol generating product 200 is heated by the laser irradiation described above, it can generate an aerosol that can be inhaled by the user.

[0157] Thus, this application can also reconfirm whether the aerosol generating product 200 has been correctly installed before the heating of the aerosol generating product 200 is triggered by detecting the user's button press or by the user making a suction action at the microphone when the aerosol generating device 100 is in normal working condition, so as to ensure the reliability and safety of the heating process.

[0158] In some embodiments, the heating control method further includes:

[0159] In response to a fourth gas flow sensor signal or a runtime signal, the first laser 21 and / or the second laser 22 are controlled to stop emitting heating lasers to stop heating the aerosol-generating article 200, wherein the fourth gas flow sensor signal is used to determine that the user's suction action has stopped.

[0160] In some embodiments, the controller 30 of the aerosol generating apparatus 100 can be used to perform the above steps. That is, the controller 30 can be used to: control the first laser 21 and / or the second laser 22 to stop emitting heating lasers in response to a fourth gas flow sensor signal or a runtime signal, so as to stop heating the aerosol generating article 200, wherein the fourth gas flow sensor signal is used to determine that the user's suction action has stopped.

[0161] In some embodiments, the processor is also configured to control the first laser 21 and / or the second laser 22 to stop emitting heating lasers in response to a fourth gas flow sensor signal or a runtime signal, so as to stop heating the aerosol generating article 200, wherein the fourth gas flow sensor signal is used to determine that the user's suction action has stopped.

[0162] Specifically, based on the above implementation method, during the process of a user inhaling aerosol using the aerosol generating device 100, it is impossible for the laser to continuously heat the aerosol generating product 200 for a long time. Therefore, in order to achieve the control of stopping heating, in some examples, when the laser is irradiating and heating the aerosol generating product 200, if the user presses a button in a preset button mode D such as short press, long press, or multiple consecutive presses, the controller 30 will receive a fourth button signal sent by the button component. At this time, the controller 30 controls all the first laser 21 and second laser 22 in the aerosol generating device 100 that are currently undergoing laser irradiation to stop laser irradiation, thereby stopping the heating of the aerosol generating product 200.

[0163] In other examples, if the gas flow sensor detects a decrease in flow rate or an increase in pressure inside the microphone, it can be assumed that the user has stopped the suction action. At this time, the gas flow sensor generates a fourth gas flow sensor signal and sends it to the controller 30. Upon receiving the fourth gas flow sensor signal, the controller 30 controls all the first lasers 21 and second lasers 22 currently undergoing laser irradiation in the aerosol generation device 100 to stop laser irradiation, thereby stopping the heating of the aerosol generation product 200.

[0164] Thus, this application can also reconfirm whether the aerosol generating product 200 has been correctly installed before the heating of the aerosol generating product 200 is triggered by detecting the user's button press or by the user making a suction action at the microphone when the aerosol generating device 100 is in normal working condition, so as to ensure the reliability and safety of the heating process.

[0165] In some embodiments, the heating control method further includes:

[0166] In response to the aerosol generating device 100 entering the second mode, a preset prompt message is sent to the user.

[0167] The preset prompt message is configured to prompt the user that the aerosol generating device 100 enters the second mode.

[0168] In some embodiments, the controller 30 of the aerosol generating device 100 can be used to perform the above steps. That is, the controller 30 can be used to send a preset prompt message to the user in response to the aerosol generating device 100 entering the second mode.

[0169] In some implementations, the processor is also configured to send a preset prompt message to the user in response to the aerosol generating device 100 entering the second mode.

[0170] Specifically, when the controller 30 of the aerosol generating device 100 receives the aforementioned photoelectric signal, it determines whether the aerosol generating product 200 is installed on the support component 10 based on the properties of the photoelectric signal itself. If it detects that the aerosol generating device 100 has been correctly installed, it controls the aerosol generating device 100 to enter the normal working mode (corresponding to the second mode). On the other hand, it can remind the user that the aerosol generating product 200 has been correctly installed and the aerosol generating device 100 has entered the normal working mode through voice, screen pop-up, vibration, etc.

[0171] Thus, this application can also provide feedback to the user to remind them that the aerosol generating device has entered the start-up mode normally.

[0172] In some embodiments, the heating control method further includes:

[0173] If it is determined that the aerosol-generating product 200 is not installed on the support assembly 10 and remains so for at least a preset time, the aerosol-generating device 100 is controlled to enter the first mode, and a second preset prompt message is sent to the user.

[0174] The second preset prompt message is configured to prompt the user that the aerosol generating device 100 has entered the first mode because the aerosol generating product 200 is not installed on the support component 10.

[0175] In some embodiments, the controller 30 of the aerosol generating device 100 can be used to perform the above steps. That is, the controller 30 can be used to: control the aerosol generating device 100 to enter a first mode and send a second preset prompt message to the user when it is determined that the aerosol generating article 200 is not installed on the support assembly 10 and remains so for at least a preset time.

[0176] In some embodiments, the processor is also configured to control the aerosol generating device 100 to enter a first mode and send a second preset prompt message to the user if it is determined that the aerosol generating article 200 is not installed on the support component 10 and remains so for at least a preset time.

[0177] Specifically, based on the above embodiments, regardless of whether the aerosol generating device 100 is in recognition mode or normal working mode, if the controller 30 detects that the current aerosol generating product 200 is not installed on the support component 10 according to the method provided in the above embodiments, and the above situation has been maintained for a period of time, in order to ensure safe use and to ensure that the aerosol generating device 100 can achieve automatic heating in normal working mode with the correct installation of the aerosol generating product 200, for example, the controller 30 sets the aerosol generating device 100 to recognition mode in the above situation, and prompts the user that the current aerosol generating product 200 is not installed correctly through voice, screen pop-up window or vibration, and the aerosol generating device 100 thus enters recognition mode. If the aerosol generating device 100 is currently in normal working mode, it can also prompt the user that the aerosol generating device 100 has exited normal working mode. In this way, on the one hand, the aerosol generating device 100 is not in normal working mode under the above conditions, ensuring safe use. On the other hand, by having the aerosol generating device 100 enter the identification mode under the above conditions, it is ensured that the aerosol generating device 100 can realize the automatic heating operation logic of normal working mode according to whether the aerosol generating matrix is ​​correctly installed.

[0178] Thus, this application can also, based on the detection that the aerosol generating product 200 is not installed properly during the repeated confirmation of the aerosol generating product 200, control the aerosol generating device 100 to return to the recognition mode, and prompt the user that the aerosol generating product 200 is not installed properly or has been pulled out, and maintain the logical basis for the automatic heating of the aerosol generating device 100 in the next cycle.

[0179] Please refer to Figure 10. A heating control method according to an embodiment of this application specifically includes the following steps:

[0180] 0001: In the second mode, the first laser 21 is controlled to intermittently emit detection lasers;

[0181] 0002: Obtain the detection feedback signal sent by the second laser 22.

[0182] The detection feedback signal is generated and determined by the reflected light from the detection laser irradiating the second laser.

[0183] 0003: Determine whether the aerosol-generating product 200 is installed on the support assembly 10 based on the detection feedback signal;

[0184] 0004: Within the third preset time period, based on the detection feedback signal, it is determined that the aerosol generating product 100 switches from the state of being installed in the support assembly 10 to the state of not being installed in the support assembly 100, and the aerosol generating device 100 is controlled to enter the first mode.

[0185] In the first mode, the first laser 21 and / or the second laser 22 are configured to identify whether the aerosol-generating article 200 is mounted on the support assembly 10, and in the first mode, the energy of the laser output by the first laser 21 and the second laser 22 is limited.

[0186] The controller 30 of the aerosol generating device 100 can be used to execute the heating control methods in steps 0001, 0002, 0003, and 0004 above. That is, the controller 30 can be used to: control the first laser 21 to intermittently emit detection lasers in the second mode; acquire the detection feedback signal sent by the second laser 22; determine whether the aerosol generating product 200 is installed in the support assembly 10 based on the detection feedback signal; and, within a third preset time period, determine whether the aerosol generating product 100 is switched from being installed in the support assembly 10 to not being installed in the support assembly 100 based on the detection feedback signal.

[0187] The processor in this embodiment is also configured to control the first laser 21 to emit a detection laser in a second mode, and to acquire a detection feedback signal sent by the second laser 22, and to determine whether the aerosol generating article 200 is installed in the support assembly 10 based on the detection feedback signal, and to determine, within a third preset time period, based on the detection feedback signal, whether the aerosol generating article 100 is switched from a state installed in the support assembly 10 to a state not installed in the support assembly 100.

[0188] Specifically, in addition to the heating control method proposed in the above embodiments, which controls the aerosol generating device 100 to enter normal working mode by detecting whether the aerosol generating product 200 and the support component 10 are correctly installed, in some other embodiments, when the aerosol generating device 100 is already in normal working mode and the first laser 21 and / or the second laser 22 irradiate the aerosol generating product 200 to heat the aerosol generating matrix to generate aerosol, the controller 30 of the aerosol generating device 100 can also control the first laser 21 to maintain the periodic emission of the detection laser during the interval of heating the aerosol generating matrix, thereby realizing further real-time detection of whether the aerosol generating product 200 and the support component 10 are correctly installed.

[0189] It is important to note that, to ensure the accuracy of mode switching control based on photoelectric signals, regardless of whether the controller 30 determines whether the aerosol generating product 200 is currently installed on the support assembly 10 based on the aforementioned photoelectric signals, if further mode switching control is to be performed based on the determination result, it is also necessary to detect the duration for which the determination result can be maintained. The change in the positional relationship between the aerosol generating product 200 and the support assembly 10 at the beginning and end of the aforementioned duration is used to determine whether the aerosol generating product 200 is installed on the support assembly 10, thereby reducing the probability of false identification. For example, if the aerosol generating product 200 is detected to be fixedly connected to the support assembly 10 at the beginning of the third preset duration, but is detected to be not fixedly connected to the support assembly 10 at the end of the third preset duration, it can be determined that the aerosol generating product 200 has been removed from the support assembly 10. At this time, to ensure the safe use of the aerosol generating device 100, the controller 30 controls the aerosol generating device 100 to re-enter the identification mode. The aforementioned third preset duration can be any value within the range of 0s to 3s.

[0190] Thus, this application enables the aerosol generating device 100 to perform two functions—detecting laser emission and receiving reflected light—when the device is in normal operating mode. It utilizes the photoelectric signal generated by the laser receiving reflected light in the photoelectric effect to determine whether the aerosol generating product 200 is in place. Furthermore, it controls the aerosol generating device 100 to re-enter the identification state when the aerosol generating product 200 is removed, thereby automatically stopping the aerosol generating device 100 when it is removed without requiring additional user intervention, thus improving the system's ease of operation and safety.

This application provides an aerosol generation system 1000, which includes an aerosol generation article 200 and an aerosol generation device 100 in any of the above embodiments. The aerosol generation device 100 is used to heat the aerosol generation matrix contained in the aerosol generation article 200.
