具体实施方式
为了便于理解本申请，下面结合附图和具体实施方式，对本申请进行更详细的说明。
本申请的一实施例提出一种气溶胶生成装置，其构造可以参见图1所示，包括：
腔室，气溶胶生成制品A可移除地接收在腔室内；
电感器L，用于在交变电流下产生变化磁场；
感受器30，至少一部分在腔室内延伸，并被配置为与电感器L感应耦合，在被变化磁场穿透下发热，进而对气溶胶生成制品A中的可抽吸材料进行加热，使气溶胶生成制品A的至少一种成分挥发，形成供抽吸的气溶胶；
电芯10，用于提供直流；优选的，电芯10为可充电的电芯。
电路20，用于控制气溶胶生成装置的整体操作。
根据产品使用中的设置，电感器L可以包括绕成螺旋状的圆柱形电 感器线圈，如图1中所示。绕成螺旋状的圆柱形电感器L可以具有范围在大约5mm到大约10mm内的半径r，并特别地半径r可以大约为7mm。绕成螺旋状的圆柱形电感器L的长度可以在大约8mm到大约14mm的范围内，电感器L的匝数大约8匝到15匝的范围内。相应地，内体积可能在大约0.15cm 3至大约1.10cm 3的范围内。
在一个优选的实施例中，电芯10提供的直流电压值在约2.5V至约9.0V的范围内，电芯10可提供的直流电流值在约2.5A至约20A的范围内。
在一个优选的实施例中，感受器30大体呈销钉或者刀片状的形状，进而对于插入至气溶胶生成制品A内是有利的；同时，感受器30可以具有大约12毫米的长度，大约4毫米的宽度和大约0.5毫米的厚度，并且可以由等级430的不锈钢(SS430)制成。作为替代性实施例，感受器30可以具有大约12毫米的长度，大约5毫米的宽度和大约0.5毫米的厚度，并且可以由等级430的不锈钢(SS430)制成。在其他的变化实施例中，感受器30还可以被构造成圆筒状或管状的形状；在使用时其内部空间形成用于接收气溶胶生成制品A的腔室，并通过对气溶胶生成制品A的外周加热的方式，生成供吸食的气溶胶。这些感受器还可以由等级420的不锈钢(SS420)、以及含有铁/镍的合金材料(比如坡莫合金)制成。
在图1所示的实施例中，气溶胶生成装置还包括用于布置电感器L和感受器30的支架40，该支架40的材质可以包括耐高温非金属材料比如PEEK或者陶瓷等。在实施中，电感器L采用缠绕在支架40的外壁上进而固定。同时，根据图1所示，该支架40的中空的管状形状，其管状中空的部分空间形成上述用于接收气溶胶生成制品A的腔室。
在可选的实施中，感受器30是由以上感受性的材质制备的，或者 是由陶瓷等耐热的基体材质外表面上电镀、沉积等形成感受材料涂层获得的。
以上由电路20在一个优选的实施方式中的结构和基本组件可以参见图2至图3所示，包括：
逆变器21，包括开关电路211和谐振电路212。开关电路211包括晶体管Q1；谐振电路212由电容器C1与电感器L并联连形成，从而构成并联LC谐振电路。
晶体管Q1在脉冲信号的驱动下交替的导通和关闭，以在电芯10与谐振电路212之间引导电流使谐振电路212产生谐振，形成流过电感器L的交变电流，从而使电感器L产生变化的磁场诱导感受器30发热。在图2-图3所示的实施例中，晶体管Q1是常用的MOS管，MOS管根据G极接收的PWM脉冲信号进而导通或者断开。在优选的实施中，PWM脉冲信号的频率介于80KHz～400KHz；更具体地，所述频率可以在大约200KHz到300KHz的范围。
在图2-图3所示的实施例中，开关电路211的导通或者断开是由驱动器23生成的PWM脉冲信号控制的，驱动器23包括驱动芯片U1及其周边电路。当然，驱动器23是基于控制器22发出的PWM脉冲控制信号生成的。在其它实施例中，PWM脉冲信号也可由集成于控制器22的驱动器生成。
在一个优选的实施中，晶体管Q1的导通时间和断开时间是不同的，即PWM脉冲信号的占空比不是50％，谐振电路212的谐振过程是非对称的，使谐振电路212维持具有足够的谐振电压保持磁场的强度。具体，以图4中示出了图3所示电路20的谐振电路212以占空比50％的对称谐振方式进行驱动下，在时间t1～t5的一个周期内谐振电流/电压的变化过程；包括：
S1，t1～t2时间段：驱动器23通过发送PWM脉冲信号至MOS管Q1的G极使MOS管导通。导通后电流i1从电芯10的正极流过电感器L，由于线圈感抗不允许电流突变；所以在t1～t2时间对电感器L充电形成线性上升的电流i1。
S2，t2～t3时间段：在t2时刻，PWM脉冲结束，MOS管Q1断开，同样由于电感器L的感抗作用，电流不能立即变0，而是呈向电容器C1充电，产生对电容器C1充电的电流i2。
直至t3时刻，电容器C1电荷充满，电流变为0；此时电感器L的磁场能量全部转为电容器C1的电场能量，在电容器C1两端达到峰值电压，MOS管Q1的D极/S极间形成的电压实际为逆相脉冲峰压与电芯10的正极输出电压之和。
S3，t3～t4时间段：电容器C1通过电感器L放电直至完毕，i3达到最大值,电容器C1两端电压逐渐下降至消失，这时电容器C1中的电能又全部转为电感器L中的磁能。同样因感抗作用流经电感器L的电流逐步变化并且是与以上S1和S2方向相反；电容器C1放电直至电感器L两端电动势反向。
S4，t4～t5时间段：在t4时刻再次导通MOS管Q1，电感器L与滤波电容C3形成回流，电感器L的能量反冲到滤波电容C3形成逐渐下降的电流i4，直至降低至0的t5时刻周期结束；而后开始下一个谐振周期。
由以上过程的描述可以知悉，在t4的时刻MOS管Q1的D极/S极间电压会过零点，并且MOS管Q1在谐振的过程中，是由D极/S极间电压过零的时刻进行切换导通/断开的状态的。
进一步图3和图4中，同步检测单元24用于检测谐振电路212的谐振电压；具体，根据图4所示，同步检测单元24主要包括过零比较 器U2，用于采样和检测MOS管Q1的D极电压信号的过零点，以便仅控制器22根据过零的时刻控制MOS管Q1导通/断开的切换。
图2的实施例中进一步提出了检测电芯10的实时电压，以便于控制晶体管Q1的电压检测电路25，包括可控开关管Q2、分压电阻R1以及分压电阻R2。可控开关管Q2在控制器22的控制信号作用下，可导通或者断开电压检测电路25。
基于电压检测电路25检测到的电芯10的实时电压，控制器22可调整输出至MOS管Q1的PWM脉冲信号的占空比和/或频率。若检测到的电芯10的实时电压较低，可加大PWM脉冲信号的占空比和/或降低PWM脉冲信号的频率；若检测到的电芯10的实时电压较高，可减小PWM脉冲信号的占空比和/或提高PWM脉冲信号的频率。在具体的实施中，可预先建立电芯10的实时电压、PWM脉冲信号的占空比和/或PWM脉冲信号的频率的关联表格，基于电压检测电路25检测到的电芯10的实时电压，通过查表的方式可以确定PWM脉冲信号的占空比和/或PWM脉冲信号的频率，从而使得控制器22根据确定的占空比和/或频率控制PWM脉冲信号。
在一个优选的实施中，控制器22被配置为，若电芯10的实时电压小于或者等于第一预设电压阈值，则根据电芯10的实时电压调整PWM脉冲信号的占空比和/或频率。
在该实施中，基于电压检测电路25检测到的电芯10的实时电压，判断电芯10的实时电压是否小于或者等于第一预设电压阈值，在电芯10的实时电压小于或者等于第一预设电压阈值的情况下，根据电芯10的实时电压调整PWM脉冲信号的占空比和/或频率。在该实施中，若电芯10的实时电压大于第一预设电压阈值，则无需调整PWM脉冲信号的占空比和/或频率。一般的，第一预设电压阈值略小于电芯10的最大工 作电压，以4.2V为例，第一预设电压阈值可以设置为4.1V。
在一个优选的实施中，控制器22被配置为，若电芯10的实时电压小于或者等于第二预设电压阈值，则以第二预设电压阈值对应的脉冲信号的占空比和/或频率，驱动晶体管Q1交替地导通和断开；其中，第二预设电压阈值小于第一预设电压阈值。
在该实施中，基于电压检测电路25检测到的电芯10的实时电压，判断电芯10的实时电压是否小于或者等于第二预设电压阈值，电芯10的实时电压小于或者等于第二预设电压阈值的情况下，以第二预设电压阈值对应的脉冲信号的占空比和/或频率，驱动晶体管Q1交替地导通和断开。一般的，第二预设电压阈值介于3V～3.6V之间；或者介于3.1V～3.6V之间；或者介于3.2V～3.6V之间；或者介于3.3V～3.6V之间；或者介于3.3V～3.5V之间。优选的，第二预设电压阈值设置为3.4V。第二预设电压阈值对应的脉冲信号的占空比和/或频率，可以预先设置，或者通过上述查表方式得到。
在一个优选的实施中，控制器22被配置为，若电芯10前后两次的实时电压的差值大于或者等于预设差值阈值，则根据电芯10当前的实时电压调整PWM脉冲信号的占空比和/或频率。
在该实施中，基于电压检测电路25检测到的电芯10的实时电压，先判断电芯10前后两次的实时电压的差值是否大于或者等于预设差值阈值，在电芯10前后两次的实时电压的差值大于或者等于预设差值阈值的情况下，根据电芯10当前的实时电压确定其对应的PWM脉冲信号的占空比和/或PWM脉冲信号的频率，从而使得控制器22根据确定的占空比和/或频率控制PWM脉冲信号。优选的，预设差值阈值设置为0.1V。
在一个优选的实施中，控制器22被配置为，在控制感受器30从初始温度上升到预设温度的期间，根据电芯10的实时电压调整PWM脉冲 信号的占空比和/或频率。
在该实施中，可通过气溶胶生成装置中设置的温度传感器(附图未示出)，获取感受器30的实时温度，从而使得控制器22控制感受器30从初始温度上升到预设温度。预设温度可以为可抽吸材料产生气溶胶的最佳温度，即可抽吸材料在该温度下可以提供最适合用户抽吸、口感较佳的烟雾量及温度。一般的，预设温度介于150℃～350℃；或者，介于180℃～350℃；或者，介于220℃～350℃；或者，介于220℃～300℃；或者，介于220℃～280℃；220℃～260℃。
在不同电芯10电压下，以相同的占空比和/或频率驱动晶体管Q1，会导致感受器30从初始温度上升到预设温度的时间不一致，例如：在4.2V、3.2V的电芯电压下，感受器30从初始温度上升到预设温度的时间会相差7～8s，进而影响用户的抽吸体验。因此，在该期间通过根据电芯10的实时电压调整PWM脉冲信号的占空比和/或频率，可以前后一致，用户的抽吸体验也较好。
进一步优选的实施中，控制器22还被配置为，在控制感受器30从初始温度上升到预设温度的期间，获取感受器30的实时温度；若感受器30的实时温度小于预设温度阈值，则根据电芯10的实时电压调整PWM脉冲信号的占空比和/或频率。
在该实施中，基于温度传感器感测到的感受器30的实时温度，判断感受器30的实时温度是否小于预设温度阈值；若感受器30的实时温度小于预设温度阈值，则根据电芯10的实时电压调整PWM脉冲信号的占空比和/或频率。否则的话，可以无需调整PWM脉冲信号的占空比和/或频率。
在一个优选的实施中，控制器22被配置为，基于所述电芯10的实时电压的电压值正相关地调整PWM脉冲信号的频率，或者基于所述电芯 10的实时电压的电压值负相关地调整PWM脉冲信号的占空比。
具体地，当接收所述电芯10的第一电压值时控制输出第一占空比的脉冲电压；当接收所述电芯10的小于第一电压值的第二电压值时控制输出第二占空比的脉冲电压；其中第一占空比小于第二占空比；
或者，当接收所述电芯10的第一电压值时控制输出第一频率的脉冲电压，当接收所述电芯10的小于第一电压值的第二电压值时控制输出第二频率的脉冲电压，其中第一频率大于第二频率。
在一个替代的实施中，控制器22被配置为，当接收所述电芯10的实时电压的电压值处于第一区间时，控制输出第一占空比或第一频率的脉冲电压，当接收所述电芯10的实时电压的电压值处于不同于第一区间的第二区间时，控制输出第二占空比或第二频率的脉冲电压。
本申请的又一实施例提出一种气溶胶生成装置的控制方法，所述方法包括：根据电芯10的实时电压调整PWM脉冲信号的占空比和/或频率。其中，气溶胶生成装置可参考前述内容，方法的实施方式可参考前述控制器22的内容，在此不作赘述。
以下结合图5，对气溶胶生成装置的控制过程进行说明：
图5是本申请实施方式提供的感受器30的温度曲线示意图，其中，温度曲线的横坐标t表示时间，纵坐标T表示温度。具体地：
t0时刻，感受器30的初始温度为T0。
t0～t1时间段，控制器22控制感受器30的加热功率以电芯10的全功率进行加热。在t1时刻，感受器30加热到目标温度T1，例如250℃。
自t0时刻开始，每间隔一段时间，控制器22通过温度传感器获取感受器30的实时温度、并通过电压检测电路25获取电芯10的实时电压；若感受器30的实时温度小于预设温度阈值，则根据电芯10的实时电压调整PWM脉冲信号的占空比和/或频率。若感受器30的实时温度不 小于预设温度阈值，则继续获取感受器30的实时温度以及电芯10的实时电压。这样，在t0～t1时间段内，通过不断的检测以及PWM脉冲信号的调整，使得无论电芯10电压的高低，感受器30从初始温度T加热到目标温度T1的时间，前后保持一致，提升用户的抽吸体验。
t1～t2时间段，控制器22控制电芯10提供给感受器30的电力并控制感受器30在目标温度T1(250℃)下保持一段时间(即t1～t2时间段)。t2时刻，控制器22可输出抽吸气溶胶的提示信号，提示用户抽吸。
t2～t3时间段，在输出可抽吸气溶胶的提示信号之后，控制器22控制电芯10提供给感受器30的加热功率并控制感受器30的温度从T1(250℃)下降到T2(例如：200℃)。随后，控制器22控制电芯10提供给感受器30的电力，以控制感受器30在T2下保持一段时间。
需要说明的是，本申请的说明书及其附图中给出了本申请的较佳的实施例，但并不限于本说明书所描述的实施例，进一步地，对本领域普通技术人员来说，可以根据上述说明加以改进或变换，而所有这些改进和变换都应属于本申请所附权利要求的保护范围。
