Technical Field

本申请涉及低温烟技术领域，具体而言，涉及一种气溶胶生成装置的控制方法和气溶胶生成装置。The present application relates to the field of low-temperature smoke technology, and in particular to a control method for an aerosol generating device and an aerosol generating device.

Background Art

传统烟草制品(例如，香烟、雪茄等)在使用过程中燃烧烟草以产生烟草烟雾，目前已存在通过加热而不燃烧的情况下释放化合物的产品来替代这些传统烟草制品。此类产品的示例为气溶胶生成装置，这些装置通常包含加热元件，加热元件用于加热插入装置中的烟支状气溶胶生成制品，从而使气溶胶生成制品中的部分活性物质受热挥发产生气溶胶。Traditional tobacco products (e.g., cigarettes, cigars, etc.) burn tobacco to generate tobacco smoke during use. Currently, there are products that release compounds by heating without burning to replace these traditional tobacco products. Examples of such products are aerosol generating devices, which generally include a heating element that is used to heat a cigarette-shaped aerosol generating product inserted into the device, so that part of the active substance in the aerosol generating product is volatilized by heat to generate an aerosol.

现有气溶胶生成装置通常通过温度感应元件来判断是热机启动还是冷机启动，进而根据热机启动还是冷机启动来针对性地控制加热元件对气溶胶生成制品进行加热，使用户在热机启动和冷机启动下的抽吸口感保持一致，但增加温度感应元件会相应的增加气溶胶生成装置的制造成本。Existing aerosol generating devices usually use temperature sensing elements to determine whether the machine is started hot or cold, and then control the heating element to heat the aerosol generating product in a targeted manner according to whether the machine is started hot or cold, so that the user's puffing taste under hot and cold start-up remains consistent. However, adding temperature sensing elements will correspondingly increase the manufacturing cost of the aerosol generating device.

图1是本申请一实施例提供的气溶胶生成装置100的结构示意图，气溶胶生成装置100包括电芯10、主板20及加热元件30，主板20上设置有气溶胶生成装置100的控制器，电芯10及加热元件30分别和控制器电连接，从而控制器可控制电芯10向加热元件30提供电能。气溶胶生成装置100中还设有纵向延伸的腔室40，腔室40用于收容和气溶胶生成装置100配套使用的烟支状的气溶胶生成制品200，加热元件30附着于腔室40的外壁从而可给腔室40中的气溶胶生成制品200进行加热，气溶胶生成制品200内部填充的部分活性物质受热挥发即可产生气溶胶，用户在气溶胶生成制品200上进行抽吸即可吸食到该气溶胶。在一些实施例中，加热元件30至少部分延伸至腔室40中，并且其伸入至腔室40中的端部被构成销钉状或者片状，以便加热元件30顺畅的插入至气溶胶生成制品200中进行加热。FIG1 is a schematic diagram of the structure of an aerosol generating device 100 provided in an embodiment of the present application. The aerosol generating device 100 includes a battery cell 10, a main board 20 and a heating element 30. A controller of the aerosol generating device 100 is provided on the main board 20. The battery cell 10 and the heating element 30 are electrically connected to the controller respectively, so that the controller can control the battery cell 10 to provide electrical energy to the heating element 30. A longitudinally extending chamber 40 is also provided in the aerosol generating device 100. The chamber 40 is used to accommodate a cigarette-shaped aerosol generating product 200 used in conjunction with the aerosol generating device 100. The heating element 30 is attached to the outer wall of the chamber 40 so as to heat the aerosol generating product 200 in the chamber 40. Part of the active material filled in the aerosol generating product 200 is volatilized by heat to generate an aerosol. The user can inhale the aerosol by inhaling on the aerosol generating product 200. In some embodiments, the heating element 30 at least partially extends into the chamber 40, and its end extending into the chamber 40 is configured to be pin-shaped or sheet-shaped so that the heating element 30 can be smoothly inserted into the aerosol generating article 200 for heating.

在一些实施例，图2是本申请另一实施例提供的气溶胶生成装置100的结构示意图，气溶胶生成装置100还可以采用电磁感应加热的方式给气溶胶生成制品200进行加热，腔室40的外壁绕制有线圈50，电芯10向线圈50中通入交变电流，线圈50在交变电流的作用下产生变化的磁场，该变化的磁场穿透加热元件30进而使加热元件30感应出涡流，加热元件30 在涡流效应以及磁滞效应的作用下产生热量，进而可对气溶胶生成制品200进行加热。在一些实施例中，加热元件包含电阻材料，电阻材料在导电时能够产生焦耳热。在一些实施例中，加热元件包含红外电热涂层，红外电热涂层在通电情况下能够产生热能，进而生成一定波长的红外线，例如：0.75μm～1000μm的红外线。在一些实施例中，加热元件可以用于直接加热气溶胶生成制品200，也可以是用于加热气流通道中的空气，将流经进气通道的空气加热成高温空气，高温空气随后进入气溶胶生成制品中，与气溶胶生成制品发生换热，实现对气溶胶生成制品的加热和烘烤。In some embodiments, FIG. 2 is a schematic diagram of the structure of an aerosol generating device 100 provided in another embodiment of the present application. The aerosol generating device 100 can also heat the aerosol generating product 200 by electromagnetic induction heating. The outer wall of the chamber 40 is wound with a coil 50. The battery core 10 passes an alternating current into the coil 50. The coil 50 generates a changing magnetic field under the action of the alternating current.

图3是根据本申请实施例的气溶胶生成装置的控制方法的流程图。如图3所示，该方法包括以下步骤：FIG3 is a flow chart of a control method of an aerosol generating device according to an embodiment of the present application. As shown in FIG3 , the method comprises the following steps:

步骤S201，启动上述气溶胶生成装置；Step S201, starting the aerosol generating device;

具体地，气溶胶生成装置可以是低温烟具，气溶胶生成制品包括含有烟草材料或者不含烟草材料的气溶胶形成基质，启动上述气溶胶生成装置之后，会唤醒控制器等元器件。Specifically, the aerosol generating device may be a low-temperature smoking device, and the aerosol generating product includes an aerosol-forming matrix containing tobacco material or not containing tobacco material. After the above-mentioned aerosol generating device is started, components such as a controller will be awakened.

步骤S202，确定上述气溶胶生成装置的关闭时长。Step S202, determining the shutdown time of the aerosol generating device.

关闭时长为气溶胶生成装置上一次的关闭时刻到当前的启动时刻的时间间隔。具体地，由于气溶胶生成装置关闭后短时间再次启动的情况下，气溶胶生成装置还没有冷却至室温，存在余热，如图4所示，气溶胶生成装置启动时的温度与启动时的当前关闭时长有关，气溶胶生成装置启动时的关闭时长为气溶胶生成装置上一次的关闭时刻到当前的启动时刻的时长，即当前关闭时长，当前关闭时长越短，气溶胶生成装置启动时的加热元件的余温越高。The shutdown duration is the time interval from the last shutdown moment of the aerosol generating device to the current startup moment. Specifically, since the aerosol generating device has not cooled to room temperature and has residual heat when it is restarted shortly after being shut down, as shown in FIG4 , the temperature of the aerosol generating device when it is started is related to the current shutdown duration when it is started. The shutdown duration when the aerosol generating device is started is the time interval from the last shutdown moment of the aerosol generating device to the current startup moment, that is, the current shutdown duration. The shorter the current shutdown duration, the higher the residual temperature of the heating element when the aerosol generating device is started.

在一些实施例中，控制器可以统计全部的关闭时长，来判断当前启动时刻距离上一次关闭时刻的时间间隔；在另一些实施例中，控制器也可以仅统计部分关闭时长，当所统计的关闭时长超过预设的时间阈值，即可确定下一次启动为冷机启动，而不再需要继续统计后面的关闭时长。In some embodiments, the controller can count the entire shutdown time to determine the time interval between the current startup time and the last shutdown time; in other embodiments, the controller can only count part of the shutdown time. When the counted shutdown time exceeds the preset time threshold, it can be determined that the next startup is a cold machine startup, and there is no need to continue counting the subsequent shutdown time.

步骤S203，根据上述关闭时长，确定上述气溶胶生成装置的预热能量，并控制上述加热元件输出上述预热能量，以使上述气溶胶生成装置达到预设的目标温度。Step S203, determining the preheating energy of the aerosol generating device according to the shutdown time, and controlling the heating element to output the preheating energy so that the aerosol generating device reaches the preheating energy. Set the target temperature.

通常情况下，启动气溶胶生成装置，即会马上对加热元件输出功率，以启动预热阶段，可对气溶胶生成制品进行预热，使气溶胶形成基质的温度增加以达到产生令人满意的量的气溶胶的温度，气溶胶可以在预热阶段中产生，但通常不会被用户抽吸出装置之外。Typically, when the aerosol generating device is activated, power is immediately output to the heating element to start the preheating phase, which can preheat the aerosol generating product to increase the temperature of the aerosol-forming substrate to reach a temperature that produces a satisfactory amount of aerosol. Aerosol can be generated during the preheating phase, but it is usually not inhaled out of the device by the user.

具体的，气溶胶生成装置启动时刻距离上一次的关闭时刻的关闭时长不同，气溶胶生成装置的加热元件在启动时刻的温度也不同，气溶胶生成装置从上述启动时刻的温度预热至目标温度所需的预热能量也不同，根据冷机启动或热机启动的不同，而给予加热元件不同的预设的预热能量，以对气溶胶生成制品加热来完成预热，即可确保预热后气溶胶生成装置达到上述气溶胶口感最佳的温度，消除余热不同而导致的口感差异。Specifically, the time between the start-up time and the last shutdown time of the aerosol generating device is different, the temperature of the heating element of the aerosol generating device at the start-up time is also different, and the preheating energy required to preheat the aerosol generating device from the temperature at the above start-up time to the target temperature is also different. Depending on whether the machine is started cold or hot, different preset preheating energies are given to the heating element to heat the aerosol generating product to complete the preheating, thereby ensuring that the aerosol generating device reaches the above-mentioned temperature for the best aerosol taste after preheating, eliminating the taste difference caused by different residual heat.

首先，启动上述气溶胶生成装置；然后，确定上述气溶胶生成装置的关闭时长，上述关闭时长为上述气溶胶生成装置上一次的关闭时刻到当前的启动时刻的时间间隔；最后，根据上述关闭时长，确定上述气溶胶生成装置的预热能量，并控制向上述加热元件输出上述预热能量，以使上述气溶胶生成装置达到预设的目标温度。该方法根据气溶胶生成装置的关闭时长确定对应的预热能量，根据不同的关闭时长来针对性地考虑气溶胶生成装置的余热对预热的影响，使得带余热的热机启动和室温下的冷机启动预热后均可达到气溶胶生成装置的气溶胶口感最佳的温度，以使得热机启动和冷机启动的气溶胶生成装置的气溶胶口感一致，并且通过关闭时长判断是热机启动还是冷机启动，无需温度传感器来判断，仅仅通过控制预热能量即可将气溶胶加热至口感最佳的温度，节省成本。First, the aerosol generating device is started; then, the shutdown duration of the aerosol generating device is determined, and the shutdown duration is the time interval from the last shutdown time of the aerosol generating device to the current startup time; finally, according to the shutdown duration, the preheating energy of the aerosol generating device is determined, and the preheating energy is controlled to be output to the heating element, so that the aerosol generating device reaches the preset target temperature. The method determines the corresponding preheating energy according to the shutdown duration of the aerosol generating device, and specifically considers the influence of the residual heat of the aerosol generating device on the preheating according to different shutdown durations, so that the aerosol of the aerosol generating device can reach the best taste temperature after preheating of the hot engine start with residual heat and the cold engine start at room temperature, so that the aerosol taste of the aerosol generating device of the hot engine start and the cold engine start is consistent, and the shutdown duration is used to determine whether it is a hot engine start or a cold engine start, without the need for a temperature sensor to determine, and the aerosol can be heated to the best taste temperature by controlling the preheating energy, saving costs.

为了方便控制向加热元件输出的预热能量，一种可选的实施方式中，上述步骤S203包括：In order to facilitate the control of the preheating energy output to the heating element, in an optional implementation, the above step S203 includes:

步骤S2031，根据上述关闭时长，确定上述气溶胶生成装置的预热时长。Step S2031, determining the preheating time of the aerosol generating device according to the shutdown time.

气溶胶生成装置内的存储器可以预先设置关闭时长与预热时长的对应关系。其中，上述预热时长为上述加热元件将上述气溶胶生成装置当前启动时的当前温度加热升高至上述目标温度(也可理解为预热阶段的最高温度)所需要的时长。The memory in the aerosol generating device can preset the corresponding relationship between the shutdown time and the preheating time. The preheating time is the time required for the heating element to heat the current temperature of the aerosol generating device when it is currently started to the target temperature (which can also be understood as the maximum temperature of the preheating stage). temperature) for a certain period of time.

步骤S2032，根据上述预热时长，控制以预定功率在上述预热时长内对上述加热元件输出上述预热能量。Step S2032: According to the preheating time, control the preheating energy to be output to the heating element at a predetermined power within the preheating time.

具体地，由于能量是功率对时间的积分，如果加热功率不固定的话，很难仅通过控制加热时间来控制加热能量，因此通过加热元件设定固定的加热功率，即可通过控制预热时长来准确控制加热元件输出的预热能量，简单方便。Specifically, since energy is the integral of power over time, if the heating power is not fixed, it is difficult to control the heating energy only by controlling the heating time. Therefore, by setting a fixed heating power through the heating element, the preheating energy output by the heating element can be accurately controlled by controlling the preheating time, which is simple and convenient.

为了方便应用，一种可选的实施方式中，上述步骤S2032包括：For the convenience of application, in an optional implementation, the above step S2032 includes:

步骤S20321，确定设定的预热时间与预热时长的差值，得到延迟时长。设定的预热时间为上述气溶胶生成制品由环境温度加热至上述目标温度过程中以上述预定功率进行预热的所需要的时长。Step S20321, determining the difference between the set preheating time and the preheating duration to obtain the delay duration. The set preheating time is the duration required for the aerosol generating product to be preheated at the predetermined power during the process of being heated from the ambient temperature to the target temperature.

步骤S20322，在上述气溶胶生成装置的开机时间达到上述延迟时长的情况下，控制上述加热元件开始加热。Step S20322: When the power-on time of the aerosol generating device reaches the delay time, the heating element is controlled to start heating.

如图5所示，①为气溶胶生成装置在冷机启动时的能量输出，②、③为气溶胶生成装置在热机启动时，在气溶胶生成装置的开机时间达到延迟时长的情况下，才启动能量输出。②、③分别代表在关闭时长不同，其输出能量或者其延迟时长而相应不同的情况。其中，②代表处于热机启动且关闭时长较长的情况，③代表处于热机启动且关闭时长较短的情况，②的延迟时长小于③的延迟时长。As shown in Figure 5, ① is the energy output of the aerosol generating device when the cold engine is started, and ② and ③ are the energy output of the aerosol generating device when the hot engine is started. When the start time of the aerosol generating device reaches the delay time, the energy output is started. ② and ③ respectively represent the situations where the output energy or the delay time is different due to different shutdown time. Among them, ② represents the situation where the hot engine is started and the shutdown time is longer, and ③ represents the situation where the hot engine is started and the shutdown time is shorter. The delay time of ② is less than the delay time of ③.

步骤S20323，在上述加热元件的加热时长达到上述预热时长的情况下，控制上述加热元件停止加热，或者进入下一个阶段，以符合下一个阶段(保温阶段)的要求来控制向加热元件的输出能量/功率。Step S20323, when the heating time of the above-mentioned heating element reaches the above-mentioned preheating time, the above-mentioned heating element is controlled to stop heating, or enter the next stage to control the output energy/power to the heating element in accordance with the requirements of the next stage (insulation stage).

具体地，气溶胶生成装置通常会设置一个固定的预热时间，以方便控制预热结束进入保温阶段的时间点，且这个固定的预热时间大于或者等于冷机启动的预热时长，以保证不管冷机启动或者热机启动均可将气溶胶生成制品预热至目标温度。如图5所示，启动后延迟一段时间再开始预热，使得预热结束进入保温阶段。Specifically, the aerosol generating device usually sets a fixed preheating time to facilitate the control of the time point when the preheating ends and enters the heat preservation stage, and this fixed preheating time is greater than or equal to the preheating time of the cold machine start, so as to ensure that the aerosol generating product can be preheated to the target temperature regardless of the cold machine start or the hot machine start. As shown in Figure 5, the preheating is delayed for a period of time after the start, so that the preheating ends and enters the heat preservation stage.

为了方便应用，一种可选的实施方式中，上述步骤S2032包括： For the convenience of application, in an optional implementation, the above step S2032 includes:

步骤S20324，在上述气溶胶生成装置启动时刻，同时控制上述加热元件开始加热。Step S20324, when the aerosol generating device is started, the heating element is controlled to start heating.

步骤S20325，在加热元件的加热时长达到目标预热时长的情况下，控制上述加热元件停止加热。Step S20325: When the heating time of the heating element reaches the target preheating time, the heating element is controlled to stop heating.

加热时长小于或者等于设定的预热时长，设定的预热时长为气溶胶生成制品由环境温度加热至目标温度过程中以预定功率进行预热的时长。The heating time is less than or equal to the set preheating time, and the set preheating time is the time for preheating the aerosol generating product at a predetermined power during the process of heating the aerosol generating product from ambient temperature to a target temperature.

如图6所示，①示出在冷机启动时的能量输出，t₀-t₁可以理解为设定的预热时间；②、③为气溶胶生成装置在热机启动时，气溶胶生成装置提前结束向加热元件的功率/能量，②、③分别代表在关闭时长不同，其输出能量相应不同的情况。其中，②代表处于热机启动且关闭时长较长的情况，③代表处于热机启动且关闭时长较短的情况，②的加热时长大于③的加热时长。As shown in Figure 6, ① shows the energy output when the cold engine is started, and t ₀ -t ₁ can be understood as the set preheating time; ② and ③ are the power/energy of the aerosol generating device to the heating element when the aerosol generating device is started in the hot engine, and the aerosol generating device stops supplying power/energy to the heating element in advance. ② and ③ represent the situations where the output energy is different due to different shutdown time. Among them, ② represents the situation where the hot engine is started and the shutdown time is longer, and ③ represents the situation where the hot engine is started and the shutdown time is shorter. The heating time of ② is longer than the heating time of ③.

具体地，气溶胶生成装置通常会设置一个固定的预热时间，以方便控制预热结束进入保温阶段的时间点，且这个固定的预热时间大于或者等于冷机启动的预热时长，以保证不管冷机启动或者热机启动均可将气溶胶生成制品预热至目标温度。如图6所示，先启动后直接预热达到预热时长，会停止加热一段时间再进入保温阶段，加热元件会先达到目标温度，继而可能降至目标温度以下，也可能维持在目标温度，以避免气溶胶生成制品的加热温度过冲，影响口感。Specifically, the aerosol generating device usually sets a fixed preheating time to facilitate the control of the time point when the preheating ends and enters the heat preservation stage, and this fixed preheating time is greater than or equal to the preheating time of the cold machine start, so as to ensure that the aerosol generating product can be preheated to the target temperature regardless of the cold machine start or the hot machine start. As shown in Figure 6, it will be started first and then directly preheated to reach the preheating time, and then stop heating for a period of time before entering the heat preservation stage. The heating element will reach the target temperature first, and then may drop below the target temperature, or it may maintain the target temperature to avoid overshoot of the heating temperature of the aerosol generating product and affect the taste.

具体地，气溶胶生成装置启动时刻，同时控制加热元件开始加热，当加热时长达到预热时长时，提前结束加热，相当于提前结束预热阶段，预热一结束即可进入保温阶段，为了提高加热效率，即使热机启动也无需等待一段时间直至满足固定的预热时间，也可以避免气溶胶生成制品的温度不符合预期的降低而影响口感。在一些实施例中，如图6所示，控制加热元件提前结束加热，加热元件会停止加热，直至满足固定的预热时间，再进入保温阶段，但可能会使得已经达到最高温度的气溶胶生成制品的温度有所回落。这两种方式适合不同的气溶胶生成制品的加热需求。Specifically, when the aerosol generating device is started, the heating element is controlled to start heating at the same time. When the heating time reaches the preheating time, the heating is ended in advance, which is equivalent to ending the preheating stage in advance. Once the preheating is completed, the insulation stage can be entered. In order to improve the heating efficiency, even if the heat engine is started, there is no need to wait for a period of time until the fixed preheating time is met. It can also avoid the temperature of the aerosol generating product not meeting the expected decrease and affecting the taste. In some embodiments, as shown in Figure 6, the heating element is controlled to end the heating in advance, and the heating element will stop heating until the fixed preheating time is met, and then enter the insulation stage, but the temperature of the aerosol generating product that has reached the highest temperature may drop. These two methods are suitable for the heating requirements of different aerosol generating products.

具体地，将关闭时长对应的目标预热时长确定为预热时长；预热时长的映射关系可以理解为关闭时长与目标预热时长的映射关系，目标预热时长为将气溶胶生成制品加热至目标温度过程中以上述预定功率进行预热的时长。Specifically, the target preheating time corresponding to the shutdown time is determined as the preheating time; the mapping relationship of the preheating time can be understood as the mapping relationship between the shutdown time and the target preheating time. The length is the length of time for preheating at the predetermined power in the process of heating the aerosol-generating article to the target temperature.

具体地，由于气溶胶生成装置启动时的关闭时长不同，加热元件被启动时的温度不同，气溶胶生成装置从述启动时刻的温度预热至目标温度所需的预热时长也不同，通过标定实验建立上述当前关闭时长与目标预热时长的映射关系，即可根据预热时长映射关系，将上述当前关闭时长对应的目标预热时长确定为预热时长。Specifically, due to the different shutdown time when the aerosol generating device is started, the temperature when the heating element is started is different, and the preheating time required for the aerosol generating device to preheat from the temperature at the start-up moment to the target temperature is also different. A mapping relationship between the above-mentioned current shutdown time and the target preheating time is established through calibration experiments. According to the preheating time mapping relationship, the target preheating time corresponding to the above-mentioned current shutdown time can be determined as the preheating time.

为了适用于更多的应用场景，一种可选的实施方式中，上述步骤S203包括：In order to be applicable to more application scenarios, in an optional implementation, the above step S203 includes:

步骤S2033，确定当前时刻上述加热元件的已供给能量；Step S2033, determining the energy supplied to the heating element at the current moment;

步骤S2034，在上述已供给能量达到当前的上述预热能量的情况下，控制上述加热元件停止加热。Step S2034, when the supplied energy reaches the current preheating energy, control the heating element to stop heating.

具体地，实际应用过程中，加热元件的加热功率可能无法保持恒定，还可以不通过时长来判断是否结束预热，而是直接通过能量是否达到预设能量来判断，使得该控制方法适用于更多的应用场景。Specifically, in actual application, the heating power of the heating element may not be able to remain constant, and the end of preheating may be determined not by duration but directly by whether the energy reaches a preset energy, making the control method suitable for more application scenarios.

为了降低功耗，一种可选的实施方式中，上述气溶胶生成装置包括控制器，在步骤S201之前，上述方法还包括：In order to reduce power consumption, in an optional implementation, the aerosol generating device includes a controller, and before step S201, the method further includes:

步骤S301，在上述气溶胶生成装置关闭的情况下，上述控制器进入定时唤醒模式，并将每次唤醒时间进行储存，进而根据上述唤醒时间确定上述关闭时长；其中，上述定时唤醒模式为上述控制器间隔固定时长唤醒一次的模式。Step S301, when the aerosol generating device is turned off, the controller enters a timed wake-up mode and stores each wake-up time, and then determines the shutdown duration based on the wake-up time; wherein the timed wake-up mode is a mode in which the controller wakes up once at a fixed time interval.

具体地，气溶胶生成装置关闭时，控制器定时唤醒模式，即进入休眠状态并间隔预定时间唤醒，根据唤醒时间即可实现计时以确定关闭时间，无需将控制器一直保持工作状态，大大降低了功耗。Specifically, when the aerosol generating device is turned off, the controller is in timed wake-up mode, that is, it enters a sleep state and wakes up at a preset interval. The timing can be realized according to the wake-up time to determine the shutdown time. There is no need to keep the controller in working state all the time, which greatly reduces power consumption.

为了进一步降低功耗，一种可选的实施方式中，在步骤S301之后，上述方法还包括：In order to further reduce power consumption, in an optional implementation manner, after step S301, the method further includes:

步骤S302，在控制器的唤醒次数大于预定次数的情况下，控制器退出定时唤醒模式，预定次数为上述气溶胶生成装置冷却至环境温度所需的最小的唤醒次数。Step S302: If the controller wakes up more than a predetermined number of times, the controller exits. In the timed wake-up mode, the predetermined number of times is the minimum number of wake-ups required for the aerosol generating device to cool to ambient temperature.

具体地，气溶胶生成装置的关闭时长超过冷机启动的最小时长时，即可不再计时，冷机启动的最小时长即冷却至环境温度所需的最小时长，根据该时长和唤醒的间隔时长即可确定预定次数，也就是说，唤醒次数超过预定次数，即可无需继续计时，直接就可以确定是冷机启动，控制器即可退出定时唤醒模式，保持休眠，进一步降低功耗。Specifically, when the shutdown time of the aerosol generating device exceeds the minimum time for cold machine start-up, the timing will stop. The minimum time for cold machine start-up is the minimum time required to cool to ambient temperature. The predetermined number of times can be determined based on this time and the interval between wake-ups. In other words, if the number of wake-ups exceeds the predetermined number, there is no need to continue timing, and it can be directly determined that it is a cold machine start-up. The controller can exit the timed wake-up mode and remain in sleep mode, further reducing power consumption.

为了进一步简化预热方法，一种可选的实施方式中，上述步骤S203包括：In order to further simplify the preheating method, in an optional implementation, the above step S203 includes:

步骤S2035,获取上述气溶胶生成装置关闭后的降温曲线，上述降温曲线为上述气溶胶生成装置关闭后的温度随时间变化的曲线；Step S2035, obtaining a cooling curve after the aerosol generating device is turned off, wherein the cooling curve is a curve of temperature change over time after the aerosol generating device is turned off;

步骤S2036,根据上述关闭时长和上述降温曲线，确定上述气溶胶生成装置当前启动时的当前温度；Step S2036, determining the current temperature of the aerosol generating device when it is currently started according to the shutdown time and the cooling curve;

步骤S2037,根据上述目标温度和上述当前温度，确定上述气溶胶生成装置的预热能量。Step S2037, determining the preheating energy of the aerosol generating device according to the target temperature and the current temperature.

具体地，如图4所示，气溶胶生成装置关闭后的温度随时间变化的曲线，根据关闭时长即可找到降温曲线对应的温度，确定气溶胶生成装置当前启动时的当前温度，从而根据目标温度和当前温度的温度差确定预热至目标温度所需的预热能量，无需通过标定实验建立上述当前关闭时长与目标预热时长的映射关系来控制预热时间实现预热，简化了预热方法。Specifically, as shown in Figure 4, the curve of the temperature change over time after the aerosol generating device is turned off can be used to find the temperature corresponding to the cooling curve according to the shutdown time, and the current temperature of the aerosol generating device when it is currently started can be determined, so as to determine the preheating energy required to preheat to the target temperature according to the temperature difference between the target temperature and the current temperature. There is no need to establish a mapping relationship between the current shutdown time and the target preheating time through a calibration experiment to control the preheating time to achieve preheating, which simplifies the preheating method.

为了保证气溶胶的口感，一种可选的实施方式中，在上述步骤S203之后，上述方法还包括：In order to ensure the taste of the aerosol, in an optional implementation, after the above step S203, the above method further includes:

步骤S401，控制上述加热元件启动保温阶段的能量供给，上述保温阶段包括多个能量输出阶段。Step S401, controlling the heating element to start the energy supply in the heat preservation stage, wherein the heat preservation stage includes a plurality of energy output stages.

具体地，如图5和图6所示，预热完成之后进入保温阶段(t₁-t₂阶段)，保温阶段可以有多个能量输出阶段。Specifically, as shown in FIG. 5 and FIG. 6 , after the preheating is completed, the heat preservation stage (t ₁ -t ₂ stage) begins, and the heat preservation stage may have multiple energy output stages.

在一些实施例中，通过确定当前的能量输出阶段的已供给能量，在已供给能量达到当前的能量输出阶段所对应的能量的情况下，控制加热元件停止当前的能量输出阶段的能量供给，再确定加热元件停止当前的能量输出阶段的能量供给的持续时长，直至持续时长达到当前的能量输出阶段所设定的冷却时长的情况下，则结束当前的能量输出阶段，并进入下一个能量输出阶段。可以理解为保温阶段，保温阶段包括多个能量输出阶段，每个能量输出阶段均包括加热一段时间，冷却一段时间，然后进入下一个能量输出阶段，每个能量输出阶段均有对应的能量供给，达到能量供给对应的持续时长即可停止加热，进行冷却，无需通过温度传感器检测温度达到目标温度停止加热，冷却时长达到该能量输出阶段对应的冷却时长即可进入下一个能量输出阶段，也无需通过温度传感器检测温度降低温度阈值进入下一个能量输出阶段，避免了温度检测不准确导致影响口感的问题。当然，各能量输出阶段不限于先加热后冷却，也可以先冷却后加热。In some embodiments, by determining the supplied energy of the current energy output stage, When the supplied energy reaches the energy corresponding to the current energy output stage, the heating element is controlled to stop the energy supply of the current energy output stage, and then the duration of the heating element stopping the energy supply of the current energy output stage is determined, until the duration reaches the cooling duration set for the current energy output stage, then the current energy output stage is ended and the next energy output stage is entered. It can be understood as a heat preservation stage, which includes multiple energy output stages, each of which includes heating for a period of time, cooling for a period of time, and then entering the next energy output stage. Each energy output stage has a corresponding energy supply, and heating can be stopped when the duration corresponding to the energy supply is reached, and cooling can be performed. There is no need to stop heating when the temperature reaches the target temperature through a temperature sensor. The cooling time reaches the cooling time corresponding to the energy output stage to enter the next energy output stage. There is no need to detect the temperature through a temperature sensor to lower the temperature threshold to enter the next energy output stage, which avoids the problem of inaccurate temperature detection affecting the taste. Of course, each energy output stage is not limited to heating first and then cooling, but can also be cooled first and then heated.

在一些实施例中，确定当前的能量输出阶段的已供给能量，在已供给能量达到当前的能量输出阶段所对应的能量的情况下，控制上述加热元件停止当前的能量输出阶段的能量供给；在停止输出能量供给的过程中，获取加热元件的实时温度，在加热元件的实时温度下降到预设低温阈值的情况下，则结束当前的能量输出阶段，并进入下一个能量输出阶段。这种方式需要温度感测元件的配合使用。In some embodiments, the supplied energy of the current energy output stage is determined, and when the supplied energy reaches the energy corresponding to the current energy output stage, the heating element is controlled to stop the energy supply of the current energy output stage; in the process of stopping the output energy supply, the real-time temperature of the heating element is obtained, and when the real-time temperature of the heating element drops to a preset low temperature threshold, the current energy output stage is ended and the next energy output stage is entered. This method requires the use of a temperature sensing element.

在一些实施例中，在向加热元件提供能量的过程中，获取加热元件的实时温度，在加热元件的实时温度上升到预设高温阈值的情况下，则控制上述加热元件停止当前的能量输出阶段的能量供给，在停止输出能量供给的过程中，获取加热元件的实时温度，在加热元件的实时温度下降到预设低温阈值的情况下，则结束当前的能量输出阶段，并进入下一个能量输出阶段。这种方式同样需要温度感测元件的配合使用。In some embodiments, in the process of providing energy to the heating element, the real-time temperature of the heating element is obtained. When the real-time temperature of the heating element rises to a preset high temperature threshold, the heating element is controlled to stop the energy supply of the current energy output stage. In the process of stopping the output energy supply, the real-time temperature of the heating element is obtained. When the real-time temperature of the heating element drops to a preset low temperature threshold, the current energy output stage is ended and the next energy output stage is entered. This method also requires the use of a temperature sensing element.

需要说明的是，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。It should be noted that although a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in an order different from that shown here.
