[0050] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0051] In some embodiments, an aerosol generating device 10 is provided, which can flexibly adjust the taste according to the demand, does not need to reserve humidification time to meet the taste requirements, and meets the user's timely smoking needs.

[0052] like Figure 3 and Figure 4 As shown, in some embodiments, a method for adjusting taste is provided, which can be applied to the above-mentioned aerosol generating device 10 to flexibly adjust the taste of the aerosol generating device 10 to meet different needs and suitable taste.

[0053] like Figure 1 and Figure 2 As shown, the taste adjustment method comprises the following steps:

[0054] Step S100 , receiving a trigger instruction and detecting a puff signal. Thus, when the control module 100 receives a corresponding trigger instruction and detects a puff signal, it can be determined that the user is puffing the aerosol generating device 10 .

[0055] Specifically, the trigger instruction can be sent to the control module 100 of the aerosol generating device 10 through an external communication device, for example, the trigger instruction can be sent to the control module 100 of the aerosol generating device 10 through a communication device such as a smart phone, a smart watch or a computer. Of course, in other embodiments, a trigger button can be provided on the outer wall of the aerosol generating device 10, and the corresponding trigger instruction can be sent to the control module 100 by pressing the trigger button. In this case, the trigger button can be electrically connected to the control module 100 through a lead.

[0056] Specifically, by setting an air pressure sensing element such as a microphone switch in the starting air passage 14, when the user inhales, air enters the starting air passage 14 and circulates in the starting air passage 14, and the air pressure sensing element such as the microphone switch detects the circulation of the airflow, thereby sending a corresponding suction signal to the control module 100, so that the control module 100 detects the suction signal.

[0057] The trigger instruction and the suction signal may be corresponding electrical signals. The control module 100 may be a single chip microcomputer, a PLC (Programmable Logic Controller) or other control elements that can be integrated into the aerosol generating device 10 .

[0058] Step S200, in response to the trigger instruction, control the substance generator to input the release component into the suction channel to form an aerosol with a preset taste. In this way, the control module 100 receives the trigger instruction and the suction signal, and can determine that the user is inhaling the aerosol generating device 10. The control module 100 can control the substance generator 200 to respond to the trigger instruction, and then make the substance generator 200 input the aerosol with a preset taste into the suction channel 11 for the user to inhale, so that the taste can be flexibly selected or adjusted to ensure the diversity of taste and meet different needs.

[0059] The material generator 200 can input aerosol with a preset taste into the suction channel 11 by ultrasonic vibration, electric heating, or using high-speed airflow to draw negative pressure, etc., as long as it can input aerosol with a preset taste into the suction channel 11.

[0060] In some embodiments, a mobile phone is used to send a trigger instruction to the control module 100 of the aerosol generating device 10. When the aerosol generating device 10 needs to be inhaled, a preset taste is selected on the APP of the mobile phone or a terminal with a graphical user interface and the corresponding trigger instruction is sent to the control module 100. When the control module 100 receives the trigger instruction and the inhalation signal, the substance generator 200 is controlled to input an aerosol with a preset taste into the inhalation channel 11.

[0061] In addition, an insertion port 13 for inserting a cigarette 1000 (a cigarette product formed by wrapping tobacco material with cigarette paper, wherein the tobacco material may be tobacco shreds, herbal substances, flavor substances, caffeine, nicotine salts, etc.) may be provided at the lower end of the suction channel 11, and a suction port 12 may be formed at the upper end of the suction channel 11. In this way, when the cigarette 1000 is inserted into the port 13, and the user inhales the aerosol generating device 10 at the suction port 12, the real smoke generated by the burning cigarette 1000 enters the suction channel 11 and enters the user's oral cavity through the suction port 12. It should be noted that the aerosol in the present application may be a particle size generally between 0.01 and 100 μm, and may be particles formed by liquids, and / or particles formed by oil bodies, and / or particles of solid particles.

[0062] In some embodiments, the trigger instruction includes at least one of humidity, concentration, functional substance, negative ion, and ultraviolet trigger instruction, and the release component includes at least one of humidity release component, concentration release component, functional substance release component, negative ion release component, and ultraviolet release component, and each of the trigger instructions corresponds to the input of a release component. It can be understood that by setting the trigger options of different functional options in the APP, different functional instructions are formed, and different functional instructions correspond to the control of the material production device to output different release components. In this embodiment, the release component can be a humidity release component that affects humidity, a concentration release component that affects aerosol concentration, a functional substance release component that affects aerosol taste, a negative ion release component that increases aerosol negative ions, and an ultraviolet release component that decomposes aerosol tar.

[0063] In some embodiments, in step S100, it further includes: S110, detecting that real smoke flows into the suction channel 11. In this way, the cigarette 1000 is inserted into the mouth 13, and the user inhales the aerosol generating device 10 at the suction port 12. When the smoke detection element detects that the real smoke generated by the burning of the cigarette 1000 enters the suction channel 11, a corresponding detection signal is sent to the control module 100. At the same time, the control module 100 receives the trigger instruction and the suction signal, and can determine that the user is inhaling the aerosol generating device 10. The control module 100 can thus control the material generator 200 to respond to the trigger instruction, thereby causing the material generator 200 to input aerosol with a preset taste into the suction channel 11, so that the aerosol with a preset taste is mixed with the real smoke generated by the burning of the cigarette 1000 for the user to inhale, thereby improving the taste.

[0064] like Figure 2 and Figure 3 As shown, in some embodiments, the mist outlet of the substance generator 200 is arranged between the suction port 12 and the insertion port 13, and a smoke sensor or other smoke detection element is arranged in the suction channel 11, and the smoke sensor or other smoke detection element is arranged near the insertion port 13. When the cigarette 1000 is inserted into the port 13, when the user inhales at the suction port 12, the real smoke generated by the burning cigarette 1000 enters the suction channel 11 and moves toward the suction port 12, so that the smoke sensor or other smoke detection element detects the real smoke, and then sends a corresponding detection signal to the control module 100. At the same time, when the control module 100 receives the trigger instruction and the suction signal, the control module 100 controls the substance generator 200 to input the aerosol of the preset taste into the suction channel 11, so that the real smoke moving toward the suction port 12 is mixed with the aerosol of the preset taste and flows out from the suction port 12 for the user to inhale.

[0065] Optionally, after step S110, it also includes: S111, when the trigger instruction is a humidity trigger instruction, detecting the humidity of the aerosol in the current suction channel. In this way, the humidity of the real cigarette smoke entering the suction channel 11 is detected by a humidity detection element such as a humidity sensor, and the humidity detection result is transmitted to the control module 100. S113, according to the humidity, inputting an aerosol of desired humidity into the suction channel 11. In this step, if the humidity of the current aerosol is less than the humidity threshold corresponding to the humidity trigger instruction, the humidity release component input into the suction channel is increased to form an aerosol with a taste corresponding to the humidity trigger instruction; if the humidity of the current aerosol is greater than the humidity threshold corresponding to the humidity trigger instruction, the humidity release component input into the suction channel is reduced or temporarily stopped to form an aerosol with a taste corresponding to the humidity trigger instruction. In this way, the control module 100 controls the substance generator 200 to input aerosol of desired humidity into the suction channel 11 according to the humidity detection result, so that the real smoke and the aerosol of desired humidity are mixed and discharged from the suction port 12, further improving the taste.

[0066] Among them, when the material generator 200 inputs aerosol into the suction channel 11 by vibration, the humidity of the aerosol can be adjusted by adjusting the vibration power; when the material generator 200 inputs aerosol into the suction channel 11 by heating, the humidity of the aerosol can be adjusted by adjusting the heating power; when the material generator 200 inputs aerosol into the suction channel 11 by drawing negative pressure through high-speed airflow, the humidity of the aerosol can be adjusted by adjusting the size of the negative pressure.

[0067] Specifically, in step S111, it includes: S1111, obtaining the current output power of the material generator 200 and the working time under the current output power; S1112, obtaining the humidification parameter according to the current output power and the working time; S1113, obtaining the humidity in the suction channel according to the number of puffs and the humidification parameter. In this way, the control module 100 is used to obtain the current output power and working time of the material generator 200, and then the corresponding humidification parameter can be obtained according to the current output power and working time of the material generator 200, that is, the amount of work done by the material generator 200 to output the released component, and then the number of puffs is obtained according to the number of puff signals obtained. Among them, the higher the number of puffs, the more frequent the puffs, which will reduce the humidity in the suction channel 11, and then the humidification parameter needs to be increased. For example, when the number of puffs is 5 times, the amount of work done by the material generator is controlled to increase, so that the humidity in the suction channel 11 is within a preset humidity value or humidity range. The humidification parameters can be increased by increasing the current output power of the substance generator 200 or extending the working time of the substance generator 200. The number of puffs can be determined based on the number of times the microphone switch is triggered. Furthermore, the relationship between the number of times the microphone is triggered and the puff time relative to the current output power of the substance generator 200 and the extended working time of the substance generator 200 can be established to achieve dynamic adjustment of humidity. In this way, the humidity can be controlled more accurately through the matching of dynamic parameters to meet user needs.

[0068] Furthermore, in step S113, it also includes: S1131, the humidity of the aerosol is detected again. If the humidity detected again deviates from the expected humidity, the suction channel 11 is assisted in humidification. In this way, the humidity of the aerosol is further detected by a humidity detection element such as a humidity sensor arranged in the suction channel 11, and the detection result is transmitted to the control module 100. If the humidity of the aerosol deviates from the expected humidity, the suction channel 11 can be assisted in humidification through the bypass channel 15, so as to adjust the humidity of the aerosol until the humidity of the aerosol reaches the expected humidity. For example, when the humidity of the aerosol is too low, the humidity of the aerosol can be increased by the auxiliary humidification element 300 of the bypass channel 15. Among them, the auxiliary humidification element 300 can adjust the humidity by vibration, heating or negative pressure. Similarly, when the mixed gas of the aerosol with a preset taste and the real cigarette smoke flows out from the suction port 12, the humidity of the mixed gas is detected and adjusted.

[0069] Optionally, after step S111 and before step S113, it also includes: S1121, detecting the humidity of the external environment. S1122, comparing the humidity of the external environment with the humidity in the suction channel to obtain a comparison parameter. S1123, correcting the expected humidity according to the comparison parameter. In this way, a humidity detection element such as a humidity sensor is used to detect the external environmental humidity and transmit the detection result to the control module 100, and another humidity detection element such as a humidity sensor is used to detect the humidity in the suction channel and transmit the detection result to the control module 100. The control module 100 compares the two detection results to obtain corresponding comparison parameters, and then can adjust the expected humidity of the aerosol input into the suction channel 11 by the substance generator 200 according to the comparison parameters, so that the expected humidity is more accurate and the taste is improved. For example, when the humidity of the external environment is high and the humidity in the suction channel is low, in order to avoid the humidity of the external environment interfering with the expected humidity (the interference is mainly low internal humidity and high external humidity. If high-humidity air is added, the humidity in the suction channel rises to a high degree), the control module 100 can control the substance generator 200 to reduce the current output power accordingly to avoid the expected humidity being too high; and when the humidity of the external environment is low and the humidity in the suction channel is high, in order to avoid the humidity of the external environment interfering with the expected humidity, the control module 100 can control the substance generator 200 to reduce the current output power accordingly to avoid the expected humidity being too low. Further, the scheme of this embodiment can also be applied to the embodiment of opening the bypass channel 15 to adjust the concentration of the aerosol. When the bypass channel 15 is opened, the external airflow can enter through the bypass channel 15. The scheme of this embodiment is set before the step of opening the bypass channel 15, so that the humidity of the external airflow can be obtained in advance, thereby judging the influence of the humidity of the suction channel after the external airflow enters the suction channel, and then controlling the substance generator 200 to adjust the current output power. The form of adjustment refers to the aforementioned embodiment and will not be repeated here.

[0070] Optionally, step S110 further includes: filtering the real cigarette smoke. In this way, large particles of impurities mixed in the real cigarette smoke are filtered out by electrostatic adsorption, filter filtering, etc., so that the taste of the real cigarette smoke is better.

[0071] In some embodiments, when the number of the released components is at least one and no real smoke is detected flowing into the inhalation channel, the at least one released component undergoes a physical or chemical reaction in the inhalation channel to obtain an aerosol with a preset taste, wherein the functional substance release component can be a mint substance that is more soothing to the throat, a fruit-flavored substance, or a chocolate-flavored substance, etc.; the concentration release component can be an aerosol formed by atomizing 20% ​​concentration of smoke oil, or an aerosol formed by atomizing 50% concentration of smoke oil, or an aerosol formed by atomizing 80% concentration of smoke oil; the humidity release component can be water vapor with a humidity of 35%, or water vapor with a humidity of 40%, or water vapor with a humidity of 65%. In some embodiments, the liquid medicine absorbed by the release tip absorbent of the substance generator is activated to transport negative oxygen ions to the suction channel; the liquid medicine absorbed by the non-woven cotton is infiltrated by the mesh magnetostrictive material in the negative ion generating chamber, which is pressed into a special shape and firmly connected to the electromechanical transducer sheet, which amplifies and focuses the mechanical vibration energy generated by the transducer to the end face, thereby activating a large amount of negative oxygen ions between the air and the liquid surface at a certain temperature and a certain vibration frequency. It is the same as the generation of negative oxygen ions by high-speed water flow or high-voltage breakdown discharge, but the latter is accompanied by ozone that is extremely harmful to human respiratory organs. The present device has ozone-free negative oxygen ions and produces liquid atomization at the same time, with nano-scale fullerene material as the release tip, which is a material close to superconductivity, with almost zero resistance, and only a weak current is needed to release the negative ions, which are equivalent to the pure ecological-level negative ions in nature, and have zero ozone release. After being inhaled by people, smoke like smoking cigarettes can be spit out from the mouth. The present device produces drug water vapor mist, and the transducer crystal in the negative ion generating room is converted into mechanical vibration at the inherent frequency point after the electric energy oscillation frequency is supplied. And / or, the material generator includes an ultraviolet light source arranged in the suction channel, and the ultraviolet light source delivers ultraviolet light to the suction channel. Of course, the release component can also be a combination of humidity release component, concentration release component, functional substance release component, negative ion release component, and ultraviolet release component, which can be flexibly combined or adjusted according to needs.

[0072] Furthermore, the number of the substance generators 200 can be adapted to the taste adjustment method. For example, six substance generators 200 can be used to input humidity release components, concentration release components, functional substance release components, negative ion release components, and ultraviolet release components into the suction channel 11. Alternatively, one substance generator 200 can be provided and at least two oil storage chambers for accommodating oil smoke of different tastes can be provided. The taste can be adjusted by connecting different oil storage chambers to the suction channel 11 and using the substance generator 200 to vaporize the oil smoke of the corresponding taste in the oil storage chamber.

[0073] Optionally, step S200 includes: inputting at least two kinds of mist into the suction channel 11, mixing the at least two kinds of mist and reacting chemically to obtain an aerosol with a preset taste. In this way, by simultaneously delivering different kinds of mist into the suction channel 11, the different kinds of mist are mixed and reacted chemically, so that the taste of the aerosol can be more varied to meet different usage requirements.

[0074] Optionally, when the number of the released components is at least one and real smoke is detected to flow into the suction channel, the released components and the real smoke undergo a physical or chemical reaction in the suction channel to obtain an aerosol with a preset taste. Specifically, the tar content in the airflow can be reduced by setting an acidic substance to dissolve and dilute the tar to a certain extent. That is, by setting a nicotine source and a volatile delivery enhancing compound source. For example, nicotine and a volatile acid (such as pyruvic acid) react with each other in the gas phase to form an aerosol of nicotine salt particles that can be inhaled by the user. Specifically:

[0075] Example 1

[0076] Preparation of 2,4-dimethyl-1,3-dioxolane-2-carboxylic acid from pyruvic acid and propylene glycol under acid catalysis:

[0077]

[0078] 2,4-dimethyl-1,3-dioxolane-2-carboxylic acid is reacted with nicotine in a gas phase to form an aerosol of nicotine 2,4-dimethyl-1,3-dioxolane-2-carboxylate particles for inhalation by a user. After the aerosol is inhaled by the user, the nicotine 2,4-dimethyl-1,3-dioxolane-2-carboxylate particles are hydrolyzed into nicotine, pyruvic acid and propylene glycol.

[0079] Example 2:

[0080] Preparation of 2-(allyloxy)propionic acid from lactic acid and allyl bromide:

[0081]

[0082] 2-(allyloxy) propionic acid is reacted with nicotine in a gas phase to form an aerosol of nicotine 2-(allyloxy) propionate particles. After the aerosol is inhaled by a user, the nicotine 2-(allyloxy) propionate particles are hydrolyzed into nicotine and lactic acid.

[0083] The boiling points of 2,4-dimethyl-1,3-dioxolane-2-carboxylic acid and 2-(allyloxy) propionic acid are similar to the boiling point of nicotine. Therefore, including one or both of 2,4-dimethyl-1,3-dioxolane-2-carboxylic acid and 2-(allyloxy) propionic acid as delivery enhancing compounds in the aerosol generating system and aerosol generating article according to the present invention advantageously enables effective reaction stoichiometry to be achieved by heating the nicotine source and the delivery enhancing compound source to substantially the same temperature. This advantageously reduces the complexity and cost of manufacturing aerosols and ensures the odor texture of the aerosol compared to devices in which the nicotine source and the delivery enhancing compound source may need to be heated to different temperatures in order to achieve effective reaction stoichiometry.

[0084] Optionally, in step S200, it further includes: S270, when the trigger instruction is a concentration trigger instruction, detecting the concentration of the aerosol in the current suction channel, and if the concentration deviates from the preset concentration, controlling the air intake of the bypass channel 15 to adjust the concentration of the aerosol. In this way, the concentration of the aerosol is detected by a concentration detection element such as a concentration sensor disposed in the suction channel 11, and the detection result is transmitted to the control module 100. If the concentration of the aerosol deviates from the preset concentration, the concentration of the aerosol can be adjusted by controlling the air intake of the bypass channel 15 until the concentration of the aerosol reaches the preset concentration. For example, if the current concentration of the aerosol is greater than the concentration threshold corresponding to the concentration trigger instruction, the air intake output to the suction channel is increased so that the aerosol concentration in the suction channel reaches the concentration corresponding to the concentration trigger instruction, and the concentration release component can be understood as air. At this time, the air intake of the bypass channel 15 can be increased to reduce the concentration of the aerosol; if the current concentration of the aerosol is less than the concentration threshold corresponding to the concentration trigger instruction, the air intake output to the suction channel is reduced so that the aerosol concentration in the suction channel reaches the concentration corresponding to the concentration trigger instruction, and the concentration release component can be understood as air. At this time, the air intake of the bypass channel 15 can be reduced to increase the concentration of the aerosol. Similarly, when the aerosol with a preset taste and the real cigarette smoke flow out of the suction port 12, the concentration of the mixed gas is detected and adjusted.

[0085] Specifically, a bypass channel 15 connected to the suction channel 11 may be provided on the side wall of the aerosol generating device 10, and a flow regulating valve or other element capable of adjusting the air intake amount may be provided in the bypass channel 15, and the flow regulating valve or other element capable of adjusting the air intake amount may be electrically connected to the control module 100. In this way, the concentration of the aerosol may be adjusted by controlling the air intake amount of the bypass channel 15.

[0086] Among them, the preset concentration can be adjusted or designed according to the actual suction demand. Furthermore, after step S270, it also includes S271, detecting the volume of the intake air. S272, when the volume of the intake air is greater than the preset volume threshold, increasing the current output power of the substance generator. In this way, the intake air volume of the bypass channel 15 is detected by using an intake air volume detection element such as a flow sensor and the detection result is transmitted to the control module 100. When it is detected that the intake air volume of the bypass channel 15 is greater than the preset volume threshold, in order to avoid the concentration of the aerosol in the suction channel 11 from decreasing, the control module 100 controls the substance generator 200 to increase the current output power so that the concentration of the aerosol in the suction channel 11 reaches the preset concentration requirement. Among them, the preset volume threshold can be flexibly adjusted or designed according to the actual use situation, and it only needs to meet the requirement that increasing the current output power of the substance generator 200 can make the concentration of the aerosol in the suction channel 11 reach the preset concentration requirement. It should be noted that the preset volume threshold can be the value of the intake volume per unit time. In some usage scenarios, it can be determined whether the user is taking a large puff based on the size of the intake volume. When the user is taking a large puff, the substance generator is controlled to increase the output power, increase the concentration of the aerosol atomized, and avoid the concentration drop when the user takes a large puff. The human body's limit exhaled volume is 5000 ml. In some embodiments, the value range of the preset volume threshold of the intake volume can be set to 200 ml to 5000 ml per unit time. Specifically, it can be 300 ml, 500 ml, 800 ml, 1000 ml, 1200 ml, 1500 ml, 1700 ml, 2000 ml, 2500 ml, 3000 ml, 3500 ml, 4000 ml, etc.

[0087] Among them, the concentration and humidity of the aerosol can be adjusted individually or simultaneously according to actual adjustment needs.

[0088] Optionally, in step S200, the method further includes: S280, learning a mapping relationship between the trigger instruction and the preset taste and storing the mapping relationship. Figure 2As shown, in this way, when the control module 100 receives the trigger instruction and responds to the trigger instruction to input the aerosol of the preset taste into the suction channel 11, the learning module is used to learn the mapping relationship between the trigger instruction and the preset taste. At the same time, the storage module is used to store the mapping relationship between the trigger instruction and the preset taste, so that the mapping relationship can be stored as experience data or expected data, and then the user's preferences or favorite tastes can be recorded and stored. S290, when the suction signal is detected again, the aerosol of the corresponding taste is input into the suction channel 11 according to the mapping relationship. In this way, the next time the aerosol generating device 10 is used, when the suction port 12 is inhaled and the control module 100 receives the suction signal, there is no need to receive the trigger instruction. The control module 100 can directly control the substance generator 200 to input the aerosol of the corresponding taste into the suction channel 11 according to the mapping relationship stored in the storage module. Of course, the next time the aerosol generating device 10 is used, the user can still trigger the trigger instruction to enable the control module 100 to control the substance generator 200 to input aerosol with a corresponding taste into the suction channel 11 .

[0089] The learning module may be any existing component with data analysis and processing functions, and the storage module may be any existing component capable of storing data.

[0090] For example, the learning module learns the release component combinations selected by the user multiple times, as well as the time periods for selecting the release components, thereby forming a corresponding curve graph of the selected combination and time, so as to know the taste that the user wants to achieve in the specific time period of each day, and then store it as the preferred taste in the storage module. When the aerosol generating device 10 is used next time, the control module 100 only needs to detect the suction signal to control the substance generator 200 to input the aerosol of the corresponding taste into the suction channel 11, thereby improving the user experience.

[0091] Optionally, after step S280, the method further includes: S281, when a trigger instruction is received again and a suction signal is detected, the aerosol is input into the suction channel 11 in response to the trigger instruction, and the taste of the aerosol is corrected according to the mapping relationship. In this way, the next time the aerosol generating device 10 is used, the control module 100 receives the corresponding trigger instruction and detects the suction signal, and the control module 100 controls the substance generator 200 to respond to the trigger instruction so that the substance generator 200 inputs the aerosol into the suction channel 11. In the process, the taste of the aerosol can be adaptively adjusted and corrected through the mapping relationship, so that the taste of the aerosol is better.

[0092] For example, the learning module learns that the user selects a mint-flavored aerosol with a concentration of 20% and a humidity of 10% for many times, so that it can be stored in the storage module as a preferred taste. When the aerosol generating device 10 is used next time, the control module 100 receives a concentration signal of 20% and detects a suction signal. When the control module 100 controls the substance generator 200 to input an aerosol with a concentration of 20% into the suction channel 11, the taste of the aerosol can be adaptively adjusted and corrected under the action of the learning module and the storage module, so that the control module 100 controls the substance generator 200 to continue to input a mint-flavored aerosol with a humidity of 10% into the suction channel 11, so that the aerosol flowing out of the suction port 12 is a mint-flavored aerosol with a concentration of 20% and a humidity of 10%. In some embodiments, the learning module defines the learned user habits as a common taste, generates a release component form that achieves the common taste, and recommends the release component form to the user. For example, when the user's common taste is 50% humidity, the learning module selects mint in the functional substance release component, and uses 5% mint functional substance release component and 35% humidity release component to form a taste similar to 50% humidity, which provides more flexible choices in the actual use stage of the user. And through the user's mobile terminal APP, the preferred scene mode selected by each user can be stored and learned. When the user wants to repeat the previous taste, he can directly select the stored scene mode.

[0093] Optionally, after step S200, the method further includes: S291, detecting the duration of the puff signal, so that the duration matches the current output power of the substance generator 200. Since the duration of each puff signal may be different, and a duration that is too long or too short may affect the concentration or humidity of the aerosol in the puff channel 11, the duration of the puff signal is detected by using a timer or other element and the detection result is transmitted to the control module 100, and the control module 100 accordingly adaptively adjusts the current output power of the substance generator 200, so that the current output power of the substance generator 200 matches the duration of the puff signal, thereby reducing or eliminating the effect of the duration of the puff signal on the concentration or humidity of the aerosol and other parameters, and ensuring the taste of the aerosol. For example, when the duration of the puff signal is long, it is determined that the user is continuously inhaling the aerosol in the puff channel. At this time, the current output power of the substance generator 200 is increased, so that the effects of the humidity drop and the concentration drop caused by the long duration of inhalation can be compensated, thereby ensuring the taste of the aerosol; when the duration is short, it is determined that the user is not continuously inhaling the aerosol in the puff channel. At this time, the current output power of the substance generator 200 is reduced, so that the effects of the humidity increase and the concentration increase caused by the short duration can be suppressed, thereby ensuring the taste of the aerosol. In this way, the humidity and concentration of the aerosol can be dynamically and accurately controlled, and the battery power can be saved, thereby increasing the battery life of the aerosol generating device.

[0094] It should be noted that the transmission or delivery of signals and data can be achieved through wire connection or Bluetooth connection, and can be flexibly selected according to actual usage conditions, as long as the transmission or delivery of signals and data can be achieved.
