加热不燃烧设备（HNB，heat not burning），是一种加热装置加上气溶胶产生基质（经过处理的烟草制品）的组合设备，外部加热装置通过高温加热到气溶胶产生基质可以出烟但是却不足以燃烧的温度（200~350℃）。在不燃烧烟草的前提下，让气溶胶产生基质发出烤烟的香味。由于点燃吸食的情况下，温度会达到350~600℃之间，只要温度达到这一区间，由于燃烧，会产生非常多的有害物质，如一氧化碳、尼古丁等生物碱、胺类、腈类、醉类、酚类、烷烃、醛类、氮氧化物等。而加热不燃烧方式，温度在300摄氏度左右不产生明火，有害物质会大大减少。HNB采用低温烘烤来加热，替代直接燃烧传统香烟，逐渐受到全球越来越多吸烟者的追捧，代表了全球烟草行业升级的新方向。Heat not burn equipment (HNB, heat not burning) is a combination of a heating device and an aerosol-generating substrate (processed tobacco product). The external heating device is heated at a high temperature until the aerosol-generating substrate can produce smoke but not Insufficient combustion temperature (200~350°C). On the premise of not burning tobacco, let the aerosol-generating substrate emit the aroma of flue-cured tobacco. When ignited and smoked, the temperature will reach between 350 and 600°C. As long as the temperature reaches this range, a lot of harmful substances will be produced due to combustion, such as carbon monoxide, nicotine and other alkaloids, amines, nitriles, alcohol, etc. Classes, phenols, alkanes, aldehydes, nitrogen oxides, etc. In the heat-not-burn method, no open flame will be generated at a temperature of about 300 degrees Celsius, and harmful substances will be greatly reduced. HNB is heated by low-temperature baking, replacing direct combustion of traditional cigarettes, and is gradually sought after by more and more smokers around the world, representing a new direction for the upgrading of the global tobacco industry.
在气溶胶形成装置的雾化过程（例如用户对一支烟的抽吸过程）中，由于不同用户的抽吸频率不同，所以不同用户在整个雾化过程中的总抽吸次数（口数）也不相同。而现有技术对每次抽吸及总抽吸次数均没有检测和记录，在气溶胶形成基质（例如烟支）中的挥发性化合物释放完时，用户并不能及时知晓，影响用户体验。In the atomization process of the aerosol forming device (such as the user's smoking process of a cigarette), since different users have different puffing frequencies, the total number of puffs (number of puffs) of different users in the entire atomization process is also different. Are not the same. However, the existing technology does not detect and record each puff and the total number of puffs. When the volatile compounds in the aerosol-forming substrate (such as a cigarette) are released, the user cannot know in time, which affects the user experience.

本发明的实施方式Embodiments of the present invention
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
图1是本发明气溶胶形成装置的抽吸检测方法实施例一的流程图，在雾化过程中，该实施例的抽吸检测方法进行以下步骤：Fig. 1 is a flowchart of Embodiment 1 of the suction detection method of the aerosol forming device of the present invention. During the atomization process, the suction detection method of this embodiment performs the following steps:
步骤S10.获取气溶胶形成装置的发热体的当前温度检测值，并根据所述当前温度检测值及预设的目标温度确定PWM信号的当前占空比，以调节所述发热体的当前发热功率；Step S10. Obtain the current temperature detection value of the heating element of the aerosol forming device, and determine the current duty cycle of the PWM signal according to the current temperature detection value and the preset target temperature, so as to adjust the current heating power of the heating element ;
在该步骤中，根据预设的目标温度及所获取的发热体的当前温度检测值，调节发热体的发热功率，其实现方法是通过计算出PWM信号合适的占空比，例如，采用PID算法计算相应的占空比，调节电子开关的导通与截止时间的比值，给发热体供给合适的电能，使其温度稳定在设定的目标温度处。In this step, the heating power of the heating element is adjusted according to the preset target temperature and the obtained current temperature detection value of the heating element, which is realized by calculating the appropriate duty cycle of the PWM signal, for example, using the PID Calculate the corresponding duty cycle, adjust the ratio of the on-time and off-time of the electronic switch, and supply appropriate electric energy to the heating element to stabilize its temperature at the set target temperature.
步骤S20.获取PWM信号的占空比，并根据所述PWM信号的占空比确定当前是否发生抽吸动作；Step S20. Obtain the duty ratio of the PWM signal, and determine whether a pumping action currently occurs according to the duty ratio of the PWM signal;
在该步骤中，当无抽吸动作发生时，发热体的温度相对稳定，PWM信号的占空比波动较小；当发生抽吸动作时，发热体的温度会发生骤变，出现短暂的下降，由于发热体的热量被瞬间带走，步骤S10在进行发热体的功率控制时，会增加PWM信号占空比，以增加电能的供给来弥补发热体热量的损失，导致抽吸时PWM信号的占空比出现跳变。因此，结合图2，当检测到PWM信号的占空比在t 11至t 12时刻之间发生突变时，可确定出用户进行了抽吸动作P。 In this step, when there is no pumping action, the temperature of the heating element is relatively stable, and the duty cycle of the PWM signal fluctuates less; when the pumping action occurs, the temperature of the heating element will change suddenly, and there will be a short-term drop , because the heat of the heating element is taken away instantly, step S10 will increase the duty cycle of the PWM signal when controlling the power of the heating element, so as to increase the supply of electric energy to compensate for the heat loss of the heating element, resulting in a loss of the PWM signal during suction. The duty cycle jumps. Therefore, referring to FIG. 2 , when it is detected that the duty ratio of the PWM signal changes suddenly between times t 11 and t 12 , it can be determined that the user has performed a pumping action P.
步骤S30.对雾化过程中的总抽吸次数进行统计，并在所述总抽吸次数达到阈值时，控制所述气溶胶形成装置进入关机状态。Step S30. Counting the total number of puffs during the atomization process, and controlling the aerosol forming device to enter a shutdown state when the total number of puffs reaches a threshold.
在该步骤中，可对雾化过程中发生的抽吸动作进行计数，当判断总抽吸次数达到阈值（例如13口）时，说明气溶胶形成基质（例如烟支）中的挥发性化合物已经释放完，此时可控制气溶胶形成装置关机，从而节省功耗。另外需说明的是，不同用户可对应不同的阈值，该阈值可由用户自行设置，也可通过自学习获取。In this step, the puff actions that occur during the atomization process can be counted. When the total number of puffs reaches a threshold (for example, 13 puffs), it means that the volatile compounds in the aerosol-forming substrate (such as cigarettes) have been exhausted. After releasing, the aerosol forming device can be controlled to shut down at this time, thereby saving power consumption. In addition, it should be noted that different users may correspond to different thresholds, and the thresholds may be set by users themselves or acquired through self-learning.
进一步地，在一个可选实施例中，步骤S20中，根据所述PWM信号的占空比确定当前是否发生抽吸动作，包括：Further, in an optional embodiment, in step S20, determining whether a pumping action currently occurs according to the duty ratio of the PWM signal includes:
对所述PWM信号的占空比进行滤波，并对滤波后的占空比进行求导，以获取所述占空比的波动率；filtering the duty cycle of the PWM signal, and deriving the filtered duty cycle to obtain the fluctuation rate of the duty cycle;
若所述波动率大于第一预设值，则确定发生抽吸动作；If the fluctuation rate is greater than a first preset value, it is determined that a pumping action occurs;
若所述波动率不大于第一预设值，则确定无发生抽吸动作。If the fluctuation rate is not greater than the first preset value, it is determined that no pumping action occurs.
在该实施例中，结合图3及图4，在雾化过程中，D1代表PWM信号的原始占空比，D2代表PWM信号滤波后的占空比，D3代表对滤波后的占空比进行求导后的占空比，P代表发生了抽吸动作，S1代表总抽吸次数。因此，可通过检测PWM信号的占空比的波动率来确定雾化过程是否发生了抽吸动作，以及对抽吸次数进行计数。In this embodiment, referring to Fig. 3 and Fig. 4, in the atomization process, D1 represents the original duty cycle of the PWM signal, D2 represents the duty cycle of the PWM signal after filtering, and D3 represents the duty cycle of the filtered duty cycle. The duty cycle after derivation, P represents the pumping action, and S1 represents the total number of pumping times. Therefore, it can be determined by detecting the fluctuation rate of the duty ratio of the PWM signal whether a puffing action occurs during the atomization process, and counting the number of puffing times.
进一步地，在一个可选实施例中，在步骤S30中，统计雾化过程中的总抽吸次数，包括：Further, in an optional embodiment, in step S30, counting the total number of puffs during the atomization process includes:
在接收到加热启动信号时，对所述总抽吸次数进行初始化；initializing the total number of puffs upon receipt of a heating start signal;
在雾化过程中，若确定发生抽吸动作，则对所述总抽吸次数进行更新。During the atomization process, if it is determined that a pumping action occurs, the total number of pumping times is updated.
在该实施例中，在对总抽吸次数进行初始化时，可将总抽吸次数初始化为0，在雾化过程中每检测到一次抽吸，则将总抽吸次数加1。In this embodiment, when initializing the total number of puffs, the total number of puffs can be initialized to 0, and every time a puff is detected during the atomization process, the total number of puffs is increased by 1.
进一步地，在一个可选实施例中，在获取气溶胶形成装置的发热体的当前温度检测值之后，还包括：Further, in an optional embodiment, after acquiring the current temperature detection value of the heating element of the aerosol forming device, it further includes:
根据所述发热体的冷热机状态，对所述当前温度检测值进行补偿处理；Compensating the current temperature detection value according to the heating and cooling state of the heating element;
而且，所述根据所述当前温度检测值及预设的目标温度确定PWM信号的当前占空比，包括：Moreover, the determining the current duty cycle of the PWM signal according to the current temperature detection value and the preset target temperature includes:
根据补偿处理后的当前温度检测值及预设的目标温度确定PWM信号的当前占空比。The current duty cycle of the PWM signal is determined according to the current temperature detection value after compensation processing and the preset target temperature.
在该实施例中，首先说明的是，在根据发热体的阻值检测值确定发热体的温度检测值时，在发热体的温度存在场分布情况下，随着加热时间的增加，发热体基体导热的增加，相同阻值情况下，温度会有一定下降的过程，此过程与发热体基体导热存在相关性。也就是说，当发热体本身为热机状态时，其挥发情况与冷机状态有差异，为了达到兼顾化合物挥发的一致性和舒适性的烟气温度，故在内部增加补偿算法，该算法为导热引起的温度下降情况，相关项为时间t和目标温度T 目标，即，实际的温度检测值T = F(R Heater) + f (t,T 目标)，其中，R Heater为发热体的阻值检测值，这样可确保整个抽吸阶段和冷机状态基本一致。 In this embodiment, it is first explained that when the temperature detection value of the heating element is determined according to the resistance detection value of the heating element, when the temperature of the heating element has a field distribution, as the heating time increases, the heating element substrate With the increase of heat conduction, under the same resistance value, the temperature will have a certain decrease process, which is related to the heat conduction of the heating element substrate. That is to say, when the heating element itself is in a hot state, its volatilization is different from that in a cold state. In order to achieve a flue gas temperature that takes into account both the consistency of volatilization and the comfort of the compound, a compensation algorithm is added internally. This algorithm is heat conduction The related items are time t and target temperature T target , that is, the actual temperature detection value T = F(R Heater ) + f (t,T target ), where R Heater is the resistance value of the heating element In this way, it can ensure that the whole suction stage and the cold machine state are basically consistent.
进一步地，在一个可选实施例中，所述预设的目标温度与时间相关，而且，所述预设的目标温度在第一阶段随时间从初始温度升高到第一预设温度；在第二阶段从所述第一预设温度下降至第二预设温度；在第三阶段稳定在所述第二预设温度，其中，所述第二预设温度低于所述第一预设温度。Further, in an optional embodiment, the preset target temperature is related to time, and the preset target temperature increases from the initial temperature to the first preset temperature over time in the first stage; Decline from the first preset temperature to a second preset temperature in the second stage; stabilize at the second preset temperature in the third stage, wherein the second preset temperature is lower than the first preset temperature temperature.
在该实施例中，结合图5所示的目标温度曲线，在第一阶段（0-t1），目标温度从初始温度升高到第一预设温度T1；在第二阶段（t1-t2），目标温度从第一预设温度T1下降至第二预设温度T2；在第三阶段（t2-t3），目标温度稳定在第二预设温度T2。通过设定第二阶段的目标温度（小于第一阶段的第一预设温度），可保证烟弹以最优温度持续产生凝胶，而且，通过在第三阶段维持第二预设温度的稳定，提升发热体向烟弹的热传导速率，因此，可提供不随时间变化的特性一致的气溶胶传送。In this embodiment, combined with the target temperature curve shown in Figure 5, in the first stage (0-t1), the target temperature is raised from the initial temperature to the first preset temperature T1; in the second stage (t1-t2) , the target temperature drops from the first preset temperature T1 to the second preset temperature T2; in the third stage (t2-t3), the target temperature stabilizes at the second preset temperature T2. By setting the target temperature of the second stage (less than the first preset temperature of the first stage), it can ensure that the cartridge continues to produce gel at the optimal temperature, and by maintaining the stability of the second preset temperature in the third stage , to increase the heat transfer rate from the heating element to the pod, therefore, it can provide aerosol transmission with consistent characteristics that do not change over time.
而且，由于目标温度曲线是理想曲线，即其为发热体对雾化基质进行静态加热过程的曲线，而用户在实际抽吸过程中，每次抽吸气雾时，气流实际会带走发热体上的一部分热量，也就是实际场景中，在用户抽吸的时刻其温度值相对于目标温度曲线中相应的时刻的温度值要小，而抽吸时偏低的温度无法按预设的温度雾化出相应的气溶胶成份，影响口感。此时，为了使发热体的实际温度与目标温度相一致，所产生的PWM信号的占空比会发生骤变，而PWM信号的占空比的突然提高，一方面，可使发热体的实际温度与目标温度相一致，以按预设的温度雾化出相应的气溶胶成份，保证用户口感不受影响；另一方面，也可反映用户当前进行了抽吸动作。Moreover, since the target temperature curve is an ideal curve, that is, it is the curve of the static heating process of the heating element on the atomized substrate, and in the actual inhalation process, each time the user inhales the aerosol, the airflow will actually take away the heating element A part of the heat above, that is, in the actual scene, the temperature value at the moment when the user is puffing is smaller than the temperature value at the corresponding time in the target temperature curve, and the low temperature during puffing cannot press the preset temperature mist The corresponding aerosol components are melted out, affecting the taste. At this time, in order to make the actual temperature of the heating element consistent with the target temperature, the duty ratio of the generated PWM signal will change suddenly, and the sudden increase of the duty ratio of the PWM signal, on the one hand, can make the actual temperature of the heating element The temperature is consistent with the target temperature, so that the corresponding aerosol components are atomized according to the preset temperature, so as to ensure that the user's taste is not affected; on the other hand, it can also reflect the user's current suction action.
进一步地，在一个可选实施例中，第一阶段的时间小于20秒；第二阶段的时间大于20秒；第三阶段的时间为200秒~600秒。Further, in an optional embodiment, the time of the first stage is less than 20 seconds; the time of the second stage is greater than 20 seconds; the time of the third stage is 200 seconds to 600 seconds.
在一个可选实施例中，本发明的气溶胶形成装置的抽吸检测方法还包括：In an optional embodiment, the suction detection method of the aerosol forming device of the present invention further includes:
获取当前的环境温度检测值，并根据所述当前的环境温度检测值对所述第二预设温度进行补偿处理。Acquiring a current ambient temperature detection value, and performing compensation processing on the second preset temperature according to the current ambient temperature detection value.
在该实施例中，当外界环境温度改变时，为了维持产品抽吸阶段的体验性，也需要对目标温度（第二预设温度）进行补偿处理，例如，当冬天环境温度（如环境温度低于15摄氏度）较低时，将会调高第二预设温度，维持抽吸到口腔的温度；当夏天温度较高时（如环境温度高于25摄氏度），将会调低第二预设温度，维持抽吸到口腔的温度。In this embodiment, when the ambient temperature changes, in order to maintain the experience of the product inhalation stage, it is also necessary to compensate the target temperature (second preset temperature). For example, when the ambient temperature in winter (such as the ambient temperature is low When the temperature is lower than 15 degrees Celsius, the second preset temperature will be increased to maintain the temperature of the suction to the mouth; when the temperature is high in summer (such as the ambient temperature is higher than 25 degrees Celsius), the second preset temperature will be lowered Temperature, to maintain the temperature of the suction to the mouth.
