[0030] The aerosol generating device 100 provided in the embodiment of the present application is used to heat the aerosol generating matrix to generate an aerosol for the user to use. Among them, the heating method can be convection, conduction, radiation or a combination thereof. The form of the aerosol generating matrix can be a liquid, a gel, a paste or a solid, etc. When the aerosol generating matrix is ​​a solid, it can be a solid in the form of crushed, granulated, powdered, granular, strip or sheet. The aerosol generating matrix includes but is not limited to materials used for medical, health, health, and beauty purposes. For example, the aerosol generating matrix is ​​a medicinal liquid, an oil, or the aerosol generating matrix is ​​a plant material, such as the roots, stems, leaves, flowers, buds, seeds, etc. of plants. That is, the embodiments of the present application do not limit the heating method, form, and use of the aerosol generating matrix.

[0031] See also Figure 1, the present application provides an aerosol generating device 100. The aerosol generating device 100 includes a supporting assembly 10, a first laser 21, a second laser 22 and a controller 30. The supporting assembly 10 is used to install an aerosol generating product 200, and the aerosol generating product 200 contains an aerosol generating matrix. The light emitting sides of the first laser 21 and the second laser 22 face the supporting assembly 10, that is, the laser light paths of the first laser 21 and the second laser 22 pass through the supporting assembly 10. In this way, when the aerosol generating product 200 is installed on the supporting assembly 10, the lasers of the first laser 21 and the second laser 22 can irradiate the aerosol generating product 200, so that the aerosol generating matrix in the aerosol generating product 200 can absorb the energy of the laser and be heated to generate an aerosol that can be inhaled by the user. The controller 30 is configured to control the first laser 21 and / or the second laser 22 to emit laser light, for example, to control whether the first laser 21 and / or the second laser 22 emit laser light, the laser power emitted, the frequency of the laser light emission, the duration of the laser light emission, etc., which are not limited here. The controller 30 can independently control the first laser 21 or the second laser 22.

[0032] In order to heat the aerosol generating substrate to a temperature capable of generating aerosols, the first laser 21 and the second laser 22 need to emit high-energy lasers so that the aerosol generating substrate absorbs sufficient energy. However, if the first laser 21 and the second laser 22 emit high-energy lasers to irradiate the support component 10 for a long time when the aerosol generating product 200 is not loaded into the aerosol generating device 100, the lasers may irradiate the positions of the support component 10 that are not resistant to laser irradiation, causing damage to the support component 10. In serious cases, there may be risks such as melting and burning of parts. If a human body accidentally touches the position irradiated by the high-energy laser for a long time, it may be burned.

[0033] Based on this, the present application provides a heating control method, which can avoid starting the first laser 21 and the second laser 22 to emit high-energy laser for a long time when the aerosol generating product 200 is not installed on the support assembly 10, so as to ensure the safety of the aerosol generating device 100.

[0034] Please combine Figure 1 and Figure 2 , the heating control party includes:

[0035] 01: Control the first laser 21 to emit detection laser;

[0036] 02: Obtaining a detection feedback signal sent by the second laser 22, the detection feedback signal is used to determine whether the detection laser irradiation irradiates the aerosol generating article 200;

[0037] 03: Determine whether the aerosol generating article 200 is installed on the support assembly according to the detection feedback signal; and

[0038] 04: When the aerosol-generating article 200 is mounted on the supporting assembly 10 , the first laser 21 and / or the second laser 22 are allowed to emit heating laser to heat the aerosol-generating article 200 .

[0039] The controller 30 of the aerosol generating device 100 can be used to execute the heating control method in the above steps 01, 02, 03 and 04. That is, the controller 30 can be used to execute: controlling the first laser 21 to emit a detection laser; obtaining a detection feedback signal sent by the second laser 22, the detection feedback signal is used to determine whether the detection laser irradiation irradiates the aerosol generating product 200; determining whether the aerosol generating product 200 is installed on the support component according to the detection feedback signal; and when the aerosol generating product 200 is installed on the support component 10, allowing the first laser 21 and / or the second laser 22 to emit a heating laser to heat the aerosol generating product 200.

[0040] The first laser 21 emits the detection laser, and can be set to periodically emit the detection laser. For example, the first laser 21 emits the detection laser once at a preset time interval.

[0041] The detection laser is a laser with less energy than the heating laser. The controller 30 can control the energy of each detection laser by controlling the power, emission frequency, and continuous emission duration of the detection laser. The energy of the detection laser can be set based on the material of the support component 10 to prevent the support component 10 from being irradiated by the detection laser and reducing its lifespan.

[0042] like Figure 1 and Figure 3 As shown, when the aerosol generating article 200 is not installed on the aerosol generating device 100, the position where the laser emitted by the first laser 21 irradiates the aerosol generating article 200 is set as the irradiated position 121. The irradiated position 121 is made of a material with a certain light-reflecting property, and when the detection laser emitted by the first laser 21 irradiates the irradiated position 121, the reflected detection laser can irradiate the second laser 22, so that the second laser 22 generates a corresponding detection feedback signal.

[0043] like Figure 1 and Figure 4As shown, when the aerosol generating article 200 is installed on the support assembly 10 of the aerosol generating device 100, the aerosol generating article 200 blocks the irradiated position 121 of the support assembly 10, resulting in that the detection laser does not irradiate the irradiated position 121 but irradiates the aerosol generating article 200. When the detection laser can irradiate the aerosol generating article 200, the returned detection laser can also irradiate the second laser 22. However, based on the different materials of the irradiated position 121 and the aerosol generating article 200, and the different optical paths of the detection laser reflected from the irradiated position 121 to the second laser 22 and the detection laser reflected from the aerosol generating article 200 to the second laser 22, the corresponding detection feedback signals are also different. For example, the detection feedback signals corresponding to the second laser generated when the aerosol generating article 200 is not installed or installed on the support assembly 10 can be distinguished according to parameters such as the intensity and frequency of the detection feedback signals. In this way, whether the aerosol generating article 200 is installed on the support assembly 10 can be determined based on the detection feedback signal.

[0044] When the aerosol generating product 200 is mounted on the support assembly 10, the controller 30 allows the first laser 21 and / or the second laser 22 to emit a heating laser, so as to heat the aerosol generating substrate in the aerosol generating product 200 with the heating laser emitted by the first laser 21 and the second laser 22, so that the aerosol generating substrate absorbs the energy of the heating laser to generate an aerosol. For example, when the aerosol generating product 200 is mounted on the support assembly 10, only the first laser 21 may be enabled to emit a heating laser; only the second laser 22 may be enabled to emit a heating laser; the first laser 21 and the second laser 22 may be enabled to emit a heating laser at the same time; the first laser 21 and the second laser 22 may be enabled alternately to emit a heating laser, and the above is not limited here.

[0045] Accordingly, when the aerosol generating article 200 is not mounted on the support assembly 10, the controller 30 does not allow the first laser 21 and / or the second laser 22 to emit the heating laser, so as to avoid the heating laser directly irradiating the support assembly 10 for a long time and causing safety hazards.

[0046] In one embodiment, the first laser 21 emits the detection laser at a preset interval. The interval time for the first laser 21 to emit the detection laser can be set according to the irradiation time of the heating laser continuously irradiating the support component 10, which may cause safety problems. For example, if the heating laser continuously irradiates the support component 10 for more than 5 seconds, it may cause safety hazards. In this case, the interval time for the first laser 21 to emit the detection laser at a time less than 5 seconds can be set, for example, the detection laser is emitted once every 4 seconds. The detection laser can be set to a laser with lower power and shorter pulse width to avoid excessive energy of the detection laser and damage to the irradiated position 121 of the support component 10.

[0047] In another embodiment, the controller 30 may control the first laser 21 to emit the detection laser at a preset interval according to the operation state of the aerosol generating device 100. The operation state of the aerosol generating device 100 indicates whether the aerosol generating device 100 is used. In this way, the controller 30 may control the first laser 21 to start emitting the detection laser when the aerosol generating device 100 is used, and accordingly, the first laser 21 is not started when the aerosol generating device 100 is not used, so as to save power consumption.

[0048] For example, the aerosol generating device 100 includes a gyroscope, which is used to detect the motion posture of the aerosol generating device 100. According to the motion posture of the aerosol generating device 100, it can be judged whether the aerosol generating device 100 is in a stationary state or in a moving state. If the aerosol generating device 100 is in a moving state, it may be caused by the action of installing the aerosol generating product 200 on the support assembly 10. Then, when the aerosol generating device 100 is in a moving state, the controller 30 controls the first laser 21 to start emitting the detection laser at a preset interval time. Among them, the aerosol generating device 100 can also include an angular velocity sensor, an accelerometer and other devices for detecting the motion posture, which is not limited here.

[0049] For another example, the aerosol generating device 100 includes a dust cover and a detection unit. The dust cover is often opened when the aerosol generating device 100 is in use. Therefore, the detection unit can send a start instruction to the controller 30 when the dust cover is opened. Based on the start instruction, the controller controls the first laser 21 to emit the detection laser at a preset interval.

[0050] See also Figure 1 In some embodiments, the controller 30 includes a microcontroller unit (MCU). The microcontroller unit MCU has good compatibility with various sensors and low cost, which is conducive to reducing the cost of the aerosol generating device 100.

[0051] See also Figure 1 In some embodiments, the support assembly 10 includes a support seat 11 and a support side wall 12, and the support side wall 12 is connected to the support seat 11. When the aerosol generating product 200 is loaded into the aerosol generating device 100, the support seat 11 can provide support for the aerosol generating product 200. The support side wall 12 can play a certain role in fixing the aerosol generating product 200 to prevent the aerosol generating product 200 from tilting, and the support side wall 12 can also block the laser to protect other parts of the aerosol generating device 100 from being irradiated by the laser.

[0052] In some embodiments, the supporting side wall 12 includes two opposite sides, one of which is provided with a light-transmitting portion 122, so that the lasers emitted by the first laser 21 and the second laser 22 can pass through the light-transmitting portion 122 and enter the supporting assembly 10; the other side is provided with an irradiated position 121, and when the aerosol generating product 200 is not loaded into the aerosol generating device 100, the lasers emitted by the first laser 21 and the second laser 22 will irradiate the irradiated position 121. In one embodiment, the irradiated position 121 is made of a high-temperature resistant light-proof material to prevent the laser from leaking out and to prevent the irradiated position 121 from being damaged by long-term irradiation of the laser.

[0053] See also Figure 1 In some embodiments, a first laser 21 may be composed of a laser emitting element, or may be composed of a plurality of laser heating elements connected in series or in parallel, which is not limited here. The number of the first lasers 21 may be one or more, for example, the number of the first lasers 21 may be 1, 2, 3 or more, which is not limited here. In the case where the number of the first lasers 21 is multiple, the control of the first laser 21 to emit the detection laser at a fixed time in step 01 may be to control some of the first lasers 21 among the multiple first lasers 21 to emit the detection laser, or may be to control each first laser 21 to emit the detection laser, which is not limited here. Similarly, in step 03, running the first laser 21 to emit the heating laser may be to allow some of the first lasers 21 among the multiple first lasers 21 to emit the heating laser, or may be to allow each first laser 21 to emit the heating laser, which is not limited here.

[0054] The second laser 22 can be the same laser as the first laser 21 or a different laser, which is not limited here. In one embodiment, the second laser 22 is the same laser as the first laser 21, so that when emitting a heating laser for heating, the heating performance of the first laser 21 and the second laser 22 has good consistency. In addition, if the second laser 22 is the same laser as the first laser 21, the second laser 22 can perform the work of the first laser 21, for example, the detection laser is emitted by the second laser 22; the first laser 21 can perform the work of the second laser 22, for example, the first laser 21 generates a photoelectric potential after receiving the detection laser reflected from the object, and the photoelectric potential generated by the first laser 21 is detected to obtain a detection feedback signal. In one embodiment, the aerosol generating device 100 includes a plurality of identical lasers, wherein a laser that can be used to emit a detection laser is used as the first laser 21, and a laser that is used to be detected by the photoelectric potential to provide a detection feedback signal is used as the second laser 22.

[0055] Similar to the first laser 21 , the number of the second laser 22 may be one or more, for example, the number of the second laser 22 may be 1, 2, 3 or more, which is not limited herein.

[0056] In some embodiments, the output power of the first laser 21 and the second laser 22 is in the range of [3W, 30W], for example, the output power may be 3W, 5W, 8W, 10W, 12W, 14W, 16W, 18W, 20W, 24W, 28W, 30W, etc., which are not listed here one by one. In this way, the laser can quickly heat the aerosol-generating substrate to a temperature capable of generating aerosols.

[0057] In some embodiments, the detection laser is a short pulse laser, the heating laser is a long pulse laser, and the pulse width of the long pulse laser is greater than the pulse width of the short pulse laser. In this way, when the aerosol generating substrate is heated by the long pulse laser, the aerosol generating substrate can absorb a large amount of energy in a short time to quickly generate aerosol; when the aerosol generating product 200 is detected whether it is loaded into the aerosol generating device 100, a short pulse laser is used to avoid irradiating the support assembly 10 with laser of excessive energy, so as to prevent the support assembly 10 from overheating and causing safety hazards.

[0058] In one embodiment, the wavelength range of the long pulse laser is [750nm, 950nm], for example, the wavelength of the long pulse laser is 750nm, 760nm, 770nm, 780nm, 790nm, 800nm, 810nm, 820nm, 830nm, 840nm, 850nm, 860nm, 870nm, 880nm, 890nm, 900nm, 910nm, 920nm, 930nm, 940nm, 950nm, etc., which are not limited here. In this way, the aerosol generating substrate is quickly heated to a temperature capable of generating aerosol.

[0059] See also Figure 3 and Figure 4 In some embodiments, the second laser 22 is a semiconductor laser. When the second laser 22 is not powered on, it is in an unexcited state. If it is irradiated by laser, it will generate a photoelectric potential due to the photoelectric effect. The detection feedback signal in step 02 can be feedback obtained by detecting the photoelectric potential of the second laser 22, for example, feedback in the form of a voltage signal, such as Figure 5 Schematic feedback voltage. The magnitude of the voltage signal corresponding to the photoelectromotive force is related to the intensity of the laser irradiating the second laser 22, and the laser irradiating the second laser 22 is the detection laser reflected by the object. The material, shape, and position of the object irradiated by the detection laser are all related to the intensity of the laser irradiating the second laser 22. Therefore, when the detection laser irradiates the irradiated position 121 or the aerosol generating product 200, the intensity of the reflected laser is different, and the photoelectromotive force generated by the reflected laser irradiating the second laser 22 is different, and the obtained detection feedback signal is also different, so that it can be determined whether the detection laser irradiates the aerosol generating product 200 according to the detection feedback signal. In this way, the second laser 22 can be used as a heating device to emit a heating laser to heat the aerosol generating matrix, and can also be used as a sensor to obtain a detection feedback signal of the detection laser irradiating the object, so that the aerosol generating device 100 does not need to set up a sensor to detect whether the aerosol generating product 200 is in the position to be heated, so as to save costs.

[0060] The following is a further description of an implementation in which the second laser 22 is used as a sensor for obtaining a detection feedback signal.

[0061] In some embodiments, taking the detection feedback signal being a feedback voltage as an example, in order to obtain the feedback voltage, during the period when the first laser 21 emits the detection laser, the second laser 22 remains in an unexcited state so as to be able to generate a corresponding feedback voltage, thereby avoiding the second laser 22 being in an excited state and unable to generate a feedback voltage.

[0062] Please combine Figure 5In one embodiment, the time period during which the first laser 21 emits the detection laser is the total time period from when the detection laser starts to be emitted, to when the reflected detection laser is reflected to the second laser 22 to generate a feedback voltage, until the generated feedback voltage disappears, so as to ensure that after one detection laser is emitted, the second laser 22 can generate a feedback voltage in response to the reflected light of the detection laser emitted this time. For example, the first laser 21 emits a detection laser once every T1 time interval, Figure 5 The total period during which the feedback voltage of period t1 exists (the time from the start of emission of the detection laser to the second laser 22 receiving the reflected detection laser is very short and can be ignored), and period t1 is taken as the period during which the first laser 21 emits the detection laser.

[0063] See also Figure 1 In some embodiments, the aerosol generating device 100 further includes a battery 50, and the battery 50 is used to power the first laser 21 and / or the second laser 22. In some embodiments, the controller 30 is electrically connected to the battery 50, and the controller 30 can control the on / off state of the battery 50 and the first laser 21 and / or the second laser 22. When the controller 30 controls the second laser 22 to be in an unpowered state, the second laser 22 is in an unexcited state.

[0064] See also Figure 6 In some embodiments, the heating control method further comprises:

[0065] 05: When the aerosol generating article 200 is not mounted on the supporting assembly 10 , the energy of the laser output by the first laser 21 and the second laser 22 is limited.

[0066] Please combine Figure 1 In some embodiments, the controller 30 can also be used to execute the method in step 05. That is, the controller 30 can also be used to limit the energy of the laser output by the first laser 21 and the second laser 22 when the aerosol generating article 200 is not installed on the supporting assembly 10.

[0067] On the one hand, limiting the energy of the laser output by the first laser 21 and the second laser 22 includes limiting the energy of the laser output by the first laser 21 and the second laser 22 within a preset energy range. The energy of the detection laser emitted by the first laser 21 is within the preset energy range, while the heating laser output by the first laser 21 and / or the second laser 22 is higher than the maximum value of the preset energy range. The preset energy range can be set according to the material of the irradiated position 121 of the support assembly 10 to prevent the irradiated position 121 from being damaged by long-term high-energy laser irradiation.

[0068] On the other hand, limiting the energy of the laser output by the first laser 21 and the second laser 22 also includes not allowing the first laser 21 and / or the second laser 22 to output laser. For example, the second laser 22 cannot output laser in an un-excited state without power, but can be used as a sensor for receiving detection laser to generate a detection feedback signal. Putting the second laser 22 in an un-excited state also belongs to limiting the energy of the laser output by the second laser 22.

[0069] See also Figure 7 In some embodiments, step 03: determining whether the aerosol generating article 200 is installed on the support assembly 11 according to the detection feedback signal, comprises:

[0070] 021: when the detection feedback signal is within the first interval, determining that the aerosol generating article 200 is installed on the supporting assembly 10; and

[0071] 022: When the detection feedback signal is within the second interval, it is determined that the aerosol generating product 200 is not installed on the supporting assembly 10, and the ranges of the first interval and the second interval do not overlap.

[0072] Please combine Figure 1 In some embodiments, the controller 30 may also be used to execute the methods in steps 021 and 022. That is, the controller 30 may also 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.

[0073] See also Figure 5 In some embodiments, the second laser 22 generates a photoelectric potential when irradiated by the reflected detection laser, and the controller 30 can detect the photoelectric potential generated by the second laser 22 to obtain a feedback voltage, and use the feedback voltage as a detection feedback signal. In other embodiments, a feedback current can be obtained based on the photoelectric potential generated by the second laser 22, and the feedback current can be used as a detection feedback signal, which is not limited here.

[0074] Taking the detection feedback signal as a feedback voltage as an example, correspondingly, the first interval refers to the first voltage interval, corresponding to Figure 5 The illustrated interval (Vth1, Vth2), the second interval refers to the second voltage interval, corresponding to Figure 5In the illustrated interval (Vth3, Vth4), when the aerosol generating article 200 is installed on the aerosol generating device 100 or not, the feedback voltage value generated by the second laser 22 is different, so that it is possible to determine whether the detection laser irradiates the aerosol generating article 200 according to the feedback voltage generated by the second laser 22, so as to determine whether the aerosol generating article 200 is installed on the support assembly 10.

[0075] like Figure 5 As shown, the first interval is a voltage range interval corresponding to the second laser 22 that can be detected when the detection laser is irradiated to the aerosol generating product 200 and then reflected to the second laser 22. If the aerosol generating product 200 is installed on the support assembly 10, when the first laser 21 emits the detection laser, the detection laser is irradiated to the aerosol generating product 200 and then reflected to the second laser 22, and the feedback voltage of 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 product 200 is installed on the support assembly 10.

[0076] Similarly, the second interval is a pre-determined voltage range interval corresponding to the second laser 22 when the detection laser is irradiated to the irradiated position 121 of the support assembly 10 and then reflected to the second laser 22. If the aerosol generating product 200 is not installed on the support assembly 10, when the first laser 21 emits the detection laser, the detection laser is irradiated to the irradiated position 121 and then reflected 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 the detection laser, the feedback voltage is not within the first interval, but the feedback voltage is within the second interval, which means that the detection laser is not irradiated to the aerosol generating product 200, but to the irradiated position 121, so that it can be determined that the aerosol generating product 200 is installed on the support assembly 10.

[0077] like Figure 5 As shown, if the feedback voltage is detected to jump from the first interval (Vth1, Vth2) to the second interval (Vth3, Vth4) in a certain period of time, that is, the aerosol generating product 200 changes from a state of not being installed on the support component 10 to a state of being installed on the support component 10, it means that the aerosol generating product 100 is inserted into the support component 10 during the jump period.

[0078] In one embodiment, the action of inserting the aerosol generating article 200 can be used as a heating start signal. For example, when the feedback voltage jumps from the first interval to the second interval, the feedback voltage signal of the first second interval (e.g. Figure 5The controller 30 uses the signal S1 as a heating start signal, and controls the first laser 21 and / or the second laser 22 to emit a heating laser to heat the aerosol generating product 200 in time according to the heating start signal.

[0079] The first interval and the second interval do not overlap, so as to avoid the situation where the feedback voltage is both in the first interval and in the second interval, and it is impossible to determine whether the detection laser irradiates the aerosol generating product 200 or the irradiated position 121. The intensity of the reflected laser can be adjusted by adjusting the shell material of the aerosol generating product 200, the material of the irradiated position 121, setting a coating, adjusting the distance between the irradiated position 121 and the first laser 21, adjusting the power of the detection laser, etc., to ensure that the first interval and the second interval do not overlap. Figure 5 As shown, for example, the range of the first interval is (Vth1, Vth2), and the range of the second interval is (Vth3, Vth4), then as long as Vth1>Vth4, or Vth3>Vth2, the first interval and the second interval can be made non-overlapping.

[0080] If the second laser 22 generates a feedback voltage, but the feedback voltage is neither within the first interval nor within the second interval, it means that the detection laser irradiates neither the aerosol generating product 200 nor the irradiated position 121 of the support assembly 10. It may be that there is a foreign object in the support assembly 10, resulting in the inability of the laser irradiation to irradiate the irradiation position 121 or the aerosol generating product 200. In this case, the heating lasers emitted by the first laser 21 and the second laser 22 may irradiate the foreign object. If the foreign object is ignited, it will cause a safety hazard. Therefore, the first laser 21 and the second laser 22 should not be allowed to emit heating lasers.

[0081] Based on this, see Figure 8 In some embodiments, the heating control method further comprises:

[0082] 06: When the detection feedback signal is outside the first interval and outside the second interval, a prompt signal is issued to prompt that there is a foreign object in the support assembly 10.

[0083] Please combine Figure 1 In some embodiments, the controller 30 can also be used to execute the method in step 06. That is, the controller 30 can also be used to send a prompt signal to indicate that there is a foreign object in the support assembly 10 when the detection feedback signal is outside the first interval and outside the second interval.

[0084] In some embodiments, the prompt signal includes a combination of one or more prompt modes such as light prompt, sound prompt, text and / or pattern prompt, etc., which are not limited here. For example, the aerosol generating device 100 also includes a prompt light. Please combine Figure 6 For example, if the feedback signal is a feedback voltage, the indicator light flashes when the feedback voltage is outside the first interval and outside the second interval. For another example, the aerosol generating device 100 further includes a buzzer, and the buzzer sounds when the feedback voltage is outside the first interval and outside the second interval.

[0085] Further, the controller 30 may be configured to not allow the first laser 21 and the second laser 22 to emit heating lasers when the detection feedback signal is outside the first interval and outside the second interval, so as to avoid igniting the foreign matter.

[0086] See also Fig. 9 In some embodiments, the heating control method further comprises:

[0087] 071: When the first laser 21 and / or the second laser 22 emits a heating laser, the first laser 21 is controlled to switch to output a detection light;

[0088] 072: Acquire an in-position feedback signal sent by the second laser 22, where the in-position feedback signal is generated when the second laser 22 is irradiated by the reflected detection light;

[0089] 073: Determine whether the aerosol generating article 200 is detached from the support assembly 10 according to the in-situ feedback signal; and

[0090] 074: When the aerosol generating article 200 is separated from the supporting assembly 10, the energy of the laser output by the first laser 21 and / or the second laser 22 is limited, and high energy consumption components of the aerosol generating device 100 are turned off.

[0091] Please combine Figure 1 In some embodiments, the controller 30 can also be used to execute the methods in the above steps 071, 072, 073 and 074. That is, the controller 30 can also be used to control the first laser 21 to switch to output detection light in a timely manner when the first laser 21 and / or the second laser 22 emits a heating laser; obtain an in-situ feedback signal sent by the second laser 22, the in-situ feedback signal is generated when the second laser 22 is irradiated by the reflected detection light; determine whether the aerosol generating article 200 is separated from the support assembly 10 according to the in-situ feedback signal; and when the aerosol generating article 200 is separated from the support assembly 10, limit the energy of the laser output by the first laser 21 and / or the second laser 22, and turn off the high energy consumption components of the aerosol generating device 100.

[0092] The detection light may be a laser with the same or different energy as the detection laser, and the energy of the detection light is less than the energy of the heating laser. The principle is the same as that of the second laser 22 receiving the reflected detection laser to generate a detection feedback signal. When the second laser 22 receives the detection light, an in-situ feedback signal can be generated, and whether the aerosol generating article 200 is separated from the support assembly 10 can be determined according to the interval of the in-situ feedback signal.

[0093] When the first laser 21 switches from outputting heating laser light to outputting detection light, the second laser 22 is correspondingly switched to an unexcited state, so that the second laser 22 can generate an in-situ feedback signal.

[0094] Please combine Fig.10 For example, when the in-position feedback signal is in the first interval (Vth1, Vth2), it is determined that the aerosol generating product 200 is installed on the supporting assembly 10; when the in-position feedback signal is in the second interval (Vth3, Vth4), it is determined that the aerosol generating product 200 has been detached from the supporting assembly 10, and the ranges of the third interval and the fourth interval do not overlap.

[0095] like Figure 5 As shown, if the feedback voltage is detected to jump from the second interval (Vth3, Vth4) to the first interval (Vth1, Vth2) in a certain period of time, that is, the aerosol generating product 200 changes from a state installed on the support component 10 to a state not installed on the support component 10, it means that the aerosol generating product 100 has been pulled out of the support component 10 during the jump period, that is, the aerosol generating product 200 has been detached from the support component 10.

[0096] If it is determined that the aerosol generating product 200 is separated from the support assembly 10, the energy of the laser output by the first laser 21 and / or the second laser 22 is limited, and the limiting method includes limiting the energy of the laser output by the first laser 21 and the second laser 22 to a preset energy range, or not allowing the first laser 21 and / or the second laser 22 to output laser. This is to avoid the high-energy laser irradiating the support assembly 10 for a long time, causing damage to the support assembly 10. In addition, when the aerosol generating product 200 is separated from the support assembly 10, the high-energy consuming components of the aerosol generating device 100 are turned off to save energy.

[0097] In one embodiment, the action of pulling out the aerosol generating article 200 can be used as a heating end signal. For example, when the feedback voltage jumps from the second interval to the first interval, the first feedback voltage signal (e.g. Fig.10 The signal S2) is used as a heating end signal, and the controller 30 limits the energy of the laser output by the first laser 21 and / or the second laser 22 according to the heating end signal.

[0098] If it is determined that the aerosol generating article 200 has not been separated from the support assembly 10, that is, the aerosol generating article 200 is still installed on the support assembly 10, the energy of the laser output by the first laser 21 and / or the second laser 22 is not limited. Not limiting the energy of the laser output by the first laser 21 and / or the second laser 22 means allowing the first laser 21 and / or the second laser 22 to output lasers at a default or preset energy, for example, allowing the first laser 21 and / or the second laser 22 to emit a heating laser. For example, in the case where it is determined that the aerosol generating article 200 has not been separated from the support assembly 10, if the heating cycle has not ended, the first laser 21 and / or the second laser 22 can be switched to emit a heating laser again.

[0099] See also Fig.11 The present application also provides an aerosol generating device 300. Figure 1 and Fig.10 , Fig.10 The aerosol generating device 300 shown is Figure 1 Compared with the aerosol generating device 100 shown in the figure, the only difference is that it also includes an airflow sensor 70, which will not be described in detail here. When the user takes a puff, the airflow sensor 70 generates a puff signal, which is used to instruct the aerosol generating device 300 to heat the aerosol generating article 200.

[0100] The aerosol generating device 300 of the present application includes a first use mode and a second use mode, and the user can switch the use mode as needed. The first use mode is a continuous heating mode. In the first heating mode, after receiving the suction signal, the controller 30 heats the aerosol generating matrix for a fixed period of time and then stops heating. The second use mode is a pump-and-stop mode, that is, the heating starts when the user takes a puff and stops when the user stops taking a puff. Fig.12 The present application also provides a heating control method, which is applicable to the above-mentioned second use mode (pump and stop mode), and the heating control method comprises the following steps:

[0101] 101: Obtaining a suction signal from the airflow sensor 70;

[0102] 102: judging whether suction is being performed according to the suction signal;

[0103] 103: When it is determined that the suction is in progress, controlling the first laser 21 to emit a detection laser;

[0104] 104: Acquire a detection feedback signal sent by the second laser 22;

[0105] 105: Determine whether the aerosol generating article 200 is installed on the support assembly 10 according to the detection feedback signal; and

[0106] 106 : When the aerosol generating article 200 is mounted on the supporting assembly 10 , the first laser 21 and / or the second laser 22 are driven to emit heating laser to heat the aerosol generating article 200 .

[0107] Since laser heating has the characteristic of concentrated energy, it can achieve an effect close to "puff and stop", that is, after the user has puffed several times (less than the maximum number of puffs that the aerosol generating matrix can take), the laser heating is stopped, and the aerosol generating matrix can continue to be used in the next heating without being carbonized by the residual heat in this heating. There may be a period of time between this use and the next use, and the aerosol generating product 200 containing the aerosol generating matrix may be pulled out during this interval. Therefore, in the second use mode, after the puff signal is detected, steps 103 to 106 are further executed to determine whether the aerosol generating product 200 is installed in the support assembly 10, and then the heating is started to improve safety. If it is determined that the aerosol generating product 200 is not installed in the support assembly 10, the low power consumption mode is entered.

[0108] The controller 30 of the aerosol generating device 300 can be used to execute the heating control method in the above steps 101, 102, 103, 104, 105 and 106. That is, the controller 30 can be used to execute: obtaining the suction signal of the airflow sensor 70; judging whether the suction is performed according to the suction signal; in the case of determining that the suction is performed, controlling the first laser 21 to emit the detection laser at a fixed time; obtaining the detection feedback signal sent by the second laser 22; determining whether the aerosol generating article 200 is installed on the support assembly 10 according to the detection feedback signal; and in the case that the aerosol generating article 200 is installed on the support assembly 10, driving the first laser 21 and / or the second laser 22 to emit the heating laser to heat the aerosol generating article 200.

[0109] Please combine Figure 1 and Fig.12 , Fig.12 Step 103, step 104, step 105 and step 106 are respectively Figure 1 Step 01, Step 02, Step 03 and Step 04 are similar, the only difference is:

[0110] First, compared with step 01, step 103 adds the prerequisite that the first laser 21 emits the detection laser at a fixed time. That is, according to step 101 and step 102, the suction signal of the airflow sensor 70 is obtained and whether the suction is performed is determined according to the suction signal. Step 103 controls the first laser 21 to emit the detection laser at a fixed time only when it is determined that the suction is performed. Accordingly, when the suction has not yet been performed, the current application scenario does not need to use the aerosol generating device 300 to generate aerosol for the user to inhale, that is, it is not necessary to start the laser heating function of the aerosol generating device 300, and it is not necessary to perform the subsequent steps 104, 105 and 106, that is, it will not consume power to start the first laser 21 to generate the detection laser, and it will not start the first laser 21 and / or the second laser 22 to emit the heating laser, so as to save energy consumption.

[0111] In one embodiment, it can be determined whether the puffing is performed according to whether the puffing signal is within a preset puffing detection interval. For example, taking the puffing signal as a voltage signal as an example, the puffing detection interval is a voltage interval, and if the puffing voltage signal is within the preset puffing detection interval, it can be determined that the puffing is performed, otherwise it is determined that the puffing is not performed.

[0112] Second, compared with step 04, in step 106, if it is determined that the aerosol generating product 200 is installed on the support assembly 10, then it must be in the case of suction, and the first laser 21 and / or the second laser 22 can be driven to emit a heating laser to heat the aerosol generating product 200. For step 04, when it is determined that the aerosol generating product 200 is installed on the support assembly 10, only the first laser 21 and / or the second laser 22 are allowed to emit a heating laser to heat the aerosol generating product 200. On the basis of allowing the first laser 21 and / or the second laser 22 to emit a heating laser to heat the aerosol generating product 200, the first laser 21 and / or the second laser 22 can be driven to emit a heating laser to heat the aerosol generating product 200 in combination with a driving signal. For example, the drive signal may be a signal generated in response to a heating instruction input by a user. When the drive signal is not received, even if the first laser 21 and / or the second laser 22 are in a state where the heating laser emission is allowed, the first laser 21 and / or the second laser 22 will not emit lasers, so as to avoid heating when the user does not need to inhale. When the drive signal is received, but the first laser 21 and / or the second laser 22 are in a state where the heating laser emission is not allowed, the first laser 21 and / or the second laser 22 will not emit lasers, so as to avoid heating due to the user's mistaken triggering of the drive signal when the aerosol generating product is not installed on the support assembly 10.

[0113] See also Figure 1The present application provides an aerosol generating system 1000 , which includes an aerosol generating article 200 and an aerosol generating device 100 in any one of the above-mentioned embodiments, and the aerosol generating device 100 is used to heat the aerosol generating substrate contained in the aerosol generating article 200 .
