Description

电子雾化装置及其控制方法 技术领域
本发明涉及雾化设备领域，尤其涉及一种电子雾化装置及其控制方法。
 背景技术
电子雾化装置是一种能把雾化器中的气溶胶形成基质雾化的装置，其具有使用安全、方便、健康、环保等优点，因此越来越受人们的关注和青睐。
现有大部分电子雾化装置都是使用恒功率加热方式来使气溶胶形成基质雾化，而目前使用的恒功率加热的控制方法通常有以下两种：
第一种：通过调制PWM波占空比的方式来获取恒定功率输出，具体地，如图1所示，将一个大周期T分成多个等时长的小周期，而且，同一个大周期的各个小周期的加热时长是固定的，即，一个大周期的占空比恒定。不同的大周期占空比可能会有些变化。而且，在每运行完一个大周期后，关闭PWM信号的输出，再通过此时的发热体电压U2与加热时的发热体电压U1来检测发热体的阻值。在这种方式中，发热体阻值的检测是不在T内的，而且一个大周期仅进行一次阻值检测，所以，在加热初期，并不能保证恒功率输出，需要几个周期后才能调整到精确的恒功率输出。
第二种：采用周期性监控发热体的电压以及流过的电流来获取当前的功率，而且，如果监控小于目标功率，则继续加热；如果大于目标功率就停下来，直到实际平均功率低于目标功率再恢复加热。但是，这种方式存在某些加热周期内输出功率过高的情况。

 本发明的实施方式
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。
首先说明的是，若要在电子雾化装置中实现恒功率加热，需要满足：在时间窗口（总时长为T）内输出的目标功率P为固定值（例如为6.5W），即，每个时间窗口所输出的能量均为P*T，就可认为是恒功率加热。在实际应用中，每个时间窗口所输出能量越接近于P*T，便认为恒功率加热的控制越精确。
图2是本发明电子雾化装置实施例一的逻辑结构图，该实施例的电子雾化装置包括相连接的控制模块11及发热体R2，而且，控制模块11用于在当前时间窗口的第一个时间小窗的加热时段控制发热体R2进行加热，在当前时间窗口的第一个时间小窗的非加热时段检测发热体R2的电阻值；在当前时间窗口的中间时间小窗的加热时段控制发热体R2进行加热，在当前时间窗口的中间时间小窗的非加热时段控制发热体R2停止加热或检测发热体R2的电阻值；在当前时间窗口的最后一个时间小窗的加热时段控制发热体R2进行加热。其中，中间时间小窗为当前时间窗口内除第一个时间小窗、最后一个时间小窗外的其它时间小窗，中间时间小窗的加热时段及最后一个时间小窗的加热时段分别与已运行完的时间小窗的消耗能量及消耗时间相关。
关于该实施例，有以下几点需说明：
（1）将一个时间窗口（总时长T例如可为8毫秒、10毫秒）划分成多个时间小窗，所划分的多个时间小窗的小窗时长肯定小于T。一般情况下，一个时间窗口内所划分的时间小窗的数量越多，越能动态反应加热过程的真实情况，也意味着精度越高。但是，在对时间窗口进行划分时，还需考虑控制模块中MCU的模数转换模块的采样时间t ADC，即，要保证每个时间小窗的小窗时长不少于2*t ADC，这样就能保证在每个时间小窗内均能采样到发热体的电压。如果所选取的模数转换模块的采样时间t ADC 很短，在时间窗口内就可以划分数量较多的时间小窗，比如可以划分100个时间小窗。在实际运用中，还需考虑到MCU的性能和计算的复杂性，进而根据实际情况来划分数量合适的时间窗口。
而且，在一个具体例子中，当前时间窗口的各个时间小窗的小窗时长相等，如图3所示，在时间窗口内，划分了n个固定时长的时间小窗，即，t 1=t 2=…=t n-1=t n，其中，t 1、t 2、…、t n-1、t n分别为第一个、第二个、…、第n-1个、第n个时间小窗的小窗时长。在一个具体应用中，考虑到计算的复杂性和控制模块中MCU的性能，在对时间窗口进行固定时长的划分时，假设一个时间窗口的总时长为8ms。当把时间窗口均分为32个时间小窗时，则每个时间小窗的小窗时长为250us。在另一个具体例子中，当前时间窗口的各个时间小窗的小窗时长不完全相等，如图4所示，t 1、t 2、…、t n-1、t n不完全相等。
（2）通常情况下，发热体在一个时间小窗内有两个运行阶段：加热时段、非加热时段，且两个时段均不为0；特殊情况下，对于最后一个时间小窗（作为能量补偿的时间小窗），可能仅有加热时段，即，整个时间小窗的小窗时长即为加热时段，非加热时段为0。在每个时间小窗的加热时段，控制模块控制发热体进行加热；对于除最后一个时间小窗外的其它时间小窗，在其非加热时段，控制模块控制发热体停止加热或检测发热体的电阻值；对于最后一个时间小窗，不管其非加热时段存在与否，均不进行发热体电阻值的检测。
而且，在一个具体例子中，当前时间窗口的各个时间小窗的加热时段相等，如图3所示，t 1A=t 2A=…=t （ n-1 ） A=t nA，其中，t 1A、t 2A、…、t （ n-1 ） A、t nA分别为第一个、第二个、…、第n-1个、第n个时间小窗的加热时段。在另一个具体例子中，当前时间窗口的各个时间小窗的加热时段不完全相等，如图4所示，t 1A、t 2A、…、t （ n-1 ） A、t nA不完全相等。
同样地，在一个具体例子中，当前时间窗口的各个时间小窗的非加热时段相等，如图3所示，t 1B= t 2B = … = t （ n-1 ） B=t nB，其中，t 1B、t 2B、…、t （ n-1 ） B、t nB分别为第一个、第二个、…、第n-1个、第n个时间小窗的非加热时段。在另一个具体例子中，当前时间窗口的各个时间小窗的加热时段不完全相等，如图4所示，t 1B、t 2B、…、t （ n-1 ） B、t nB不完全相等。
（3）在一个时间窗口内，第一个时间小窗的非加热时段是用来检测发热体的电阻值的，且后续的中间时间小窗的非加热时段也可用来检测发热体的电阻值，而发热体电阻值的检测是为了调整本时间窗口内的后续时间小窗的能量释放方式，即，根据已运行完的时间小窗的消耗能量（消耗能量与所检测的发热体电阻值相关）及消耗时间，动态调整后续时间小窗的加热时段，从而保证发热体在一个时间窗口内的释放能量接近于总目标能量。
而且，在一个具体例子中，可在除最后一个时间小窗外的其它所有的时间小窗的非加热时段均进行发热体电阻值的检测，如图3或图4所示。在另一个具体例子中，如果发热体的阻值固定不变或者阻值随温度变化而变化极小，那么，可以仅在第一个时间小窗的非加热时段进行发热体的阻值的检测，其它的时间小窗的非加热时段不进行阻值检测，如图5所示。当然，在其它的一些具体例子中，除在第一个时间小窗的非加热时段进行电阻值检测外，还可在部分的中间时间小窗的非加热时段进行阻值检测。
下面结合图1及图3-5来说明本发明方案与现有方案的发热体电压与时间的关系曲线的区别：
（1）对于现有的PWM控制方式，如图1所示，每个时间窗口内频率不变（即，各个小周期的时长固定），每个时间窗口的占空比固定（即，各个小周期的加热时段固定），当然，不同时间窗口内，占空比可能会有变化。例如，假设时间窗口的时长T = 8ms，PWM信号的频率是4KHz，这样，在一个时间窗口内，共有32个小周期，每个小周期的时长为250us。而且，在每个小周期内，加热时长是固定的，假设其占空比是60%，那么，每个小周期的加热时长为150us（250 us *60%），非加热时长为90us。对于本发明控制模块的控制方式，一个时间窗口内，各个时间小窗的小窗时长可相等（如图3所示），也可不相等（如图4所示），而且，各个时间小窗的加热时段可相等（如图3所示），也可不相等（如图4所示）。
（2）对于现有的PWM控制方式，如图1所示，在运行完一个时间窗口之后，才去检测发热体的电阻值。电阻值的检测时段不占用时间窗口，而且，电阻值的检测目的是：调整下一个时间窗口的功率，即，调整下个时间窗口的占空比，具体地，如果本时间窗口内的平均功率（与发热体的电阻值相关）大于目标功率，则降低下一个时间窗口的占空比（例如，占空比改成50%，加热时长=125us，非加热时长为125us）；如果本时间窗口内的平均功率小于目标功率，则提高下一个时间窗口的占空比（例如，占空比改成70%，加热时长=175us，非加热时长为75us）。也就是说，一个时间窗口内的各个小周期的加热时长与非加热时长是在本时间窗口开始前就已确定好，且后续保持不变。所以，PWM控制方式只能让后面周期的平均功率接近于目标功率，但在加热初期很难保证恒功率输出。对于本发明控制模块的控制方式，如图3-5所示，在每个时间窗口内，至少会在第一个时间小窗的非加热时段进行发热体电阻值的检测，当然，也可在后续的中间时间小窗的非加热时段进行发热体电阻值的检测，最后一个时间小窗为能量补偿窗口，并不进行发热体电阻值的检测。而发热体电阻值的检测目的是：在本时间窗口内调整后续时间小窗的能量释放的方式，也就是说，在一个时间窗口内，各个时间小窗的加热时段及非加热时段并不是预先确定好的，而是实时地根据已消耗的能量及时间进行动态调整的，这样便可保证每个时间窗口的平均功率均可接近目标功率，因此，即使在加热初期，也能保证恒功率输出。
通过该实施例的技术方案，由于在每个时间窗口内均可根据发热体已运行完的时间小窗的运行情况来实时调整待运行的时间小窗的加热时长，所以，即使在加热初期，也能精确保证发热体在一个时间窗口内的释放能量接近于总目标能量，不需要经过多个周期的调整，因此，恒功率输出精度更高。
进一步地，在一个可选实施例中，当前时间窗口的第一个时间小窗的加热时段及非加热时段为初始设置值。在一个具体应用中，假设MCU的模数转换模块的采样时长t ADC为50微秒，目标功率为6.5w，加热时功率约为10W（加热时电压3V多，发热体的电阻值大概为1欧），每个时间小窗的小窗时长为250 us，那么，先根据加热功率和发热体的电阻初始值，可以推算，每个时间小窗的加热时段约为6.5W*250us/10W = 162.5us，所以可将第一个时间小窗的加热时段t 1A设置为160us，非加热时段t 1B设置为90us（均满足大于t ADC）。
在另一个可选实施例中，当前时间窗口的第一个时间小窗的加热时段及非加热时段与前一时间窗口内多个时间小窗的运行情况相关。
进一步地，在一个具体实施例中，中间时间小窗的小窗时长通过公式1确定：
t x = t left(x-1) / g x         公式1
其中，t x为第x个时间小窗的小窗时长，且x=2、3、…、n-1，n为当前时间窗口的时间小窗的总数量，g x为与第x个时间小窗所对应的设置值，且g x为大于1的整数。
在该实施例中，可预先设置不同时间小窗分别所对应的设置值，针对不同的g x的取值，可以实现当前时间窗口内的多个时间小窗为非固定时长的时间小窗，也可以实现当前时间窗口内的多个时间小窗为固定时长的时间小窗，例如，特殊情况下，当x=2时，g 2=31；当x=3时，g 3=30，以此类推，等等。
进一步地，在一个可选实施例中，中间时间小窗的加热时段及最后一个时间小窗的加热时段分别与前一时间小窗的实际功率、当前时间窗口的剩余时长、当前时间窗口的剩余能量相关。在该实施例中，当确定出第一个时间小窗的加热时段t 1A（例如160us）及非加热时段t 1B（例如为90us）后，便可根据第一个时间小窗内的实际功率、当前的剩余时长、剩余能量，确定第二个时间小窗的加热时段t 2A及非加热时段t 2B，等等，以此类推，直至确定出最后一个时间小窗的加热时段t nA及非加热时段t nB（如果存在）。
在一个具体实施例中，对于中间时间小窗，即，第x个时间小窗，x=2、3、…、n-1，n为当前时间窗口的时间小窗的总数量，其加热时段的确定方式分以下两种情况：
第一种：若在中间时间小窗的非加热时段控制发热体停止加热，则该中间时间小窗的加热时段通过公式2确定：
t left(x-1) *P t(x-1)A * t xA/ t x = E left(x-1)   公式2；
第二种：若在中间时间小窗的非加热时段检测发热体的电阻值，则该中间时间小窗的加热时段通过公式3确定：
t left(x-1) *（P t(x-1)A * t xA + P t(x-1)B *（t x- t xA））/ t x = E left(x-1)   公式3；
其中，t x为第x个时间小窗的小窗时长，t xA为第x个时间小窗的加热时段，t left(x-1)为当前时间窗口的剩余时长，P t(x-1)A为所述发热体在第x-1个时间小窗的加热时段的第一实际功率，P t(x-1)B为所述发热体在第x-1个时间小窗的非加热时段的第二实际功率，E left(x-1) 为当前时间窗口的剩余能量。
在该实施例中，由于在确定各个中间小窗的加热时段时，总是以剩余能量在剩余时长内均匀释放为原则进行确定的，所以可保证总目标能量（P*T）在一个时间窗口内释放的更均匀。
在一个具体实施例中，对于最后一个时间小窗，其加热时段可根据以下方式确定：
若所述发热体在倒数第二个时间小窗的加热时段的第一实际功率大于等于当前时间窗口的剩余能量与剩余时长的比值，则将所述比值作为所述最后一个时间小窗的加热时段；
若所述发热体在倒数第二个时间小窗的加热时段的第一实际功率小于当前时间窗口的剩余能量与剩余时长的比值，则将所述剩余时长作为所述最后一个时间小窗的加热时段。
在该实施例中，在当前时间窗口内，当运行完第n-1个时间小窗后，对于待运行的第n个时间小窗，如果P t(n-1)A * t left(n-1)>= E left(n-1)，那么，第n个时间小窗的加热时段为 E left(n-1)/ P t(n-1)A，相应地，非加热时段为t left(n-1) - E left(n-1)/ P t(n-1)A；如果P t(n-1)A * t left(n-1) < E left(n-1)，那么，第n个时间小窗的加热时长为t left(n-1)。
图6是本发明电子雾化装置实施例二的逻辑结构图，该实施例的电子雾化装置包括控制模块11、发热体R2、第一开关电路12、第二开关电路13、参考电阻R1和电压采样模块14，另外还可包括电源15。其中，第二开关电路13的第一端与第一开关电路12的第一端分别连接电源15的正端，第二开关电路13的第二端连接参考电阻R1的第一端，参考电阻R1的第二端及第一开关电路12的第二端分别连接发热体R2的第一端，发热体R2的第二端与电源15的负端接地，电压采样模块14的输入端连接发热体R2的第一端，电压采样模块14的输出端连接控制模块11的电压检测端。
下面结合图3至图6说明发热体R2电阻值的检测过程：
首先，发热体R1可选取电阻发热丝，在加热的过程中，发热体R2的阻值是有可能会随温度而发生变化的。参考电阻R1（电阻值已知）一般选取阻值是发热体R2的阻值的好几倍的电阻。
在开始运行某一个时间小窗时，在该时间小窗的加热时段，控制模块11控制第一开关电路12导通，同时，控制第二开关电路13关闭，此时，电源15给发热体R2供电，发热体R2开始发热，另外，控制模块11还通过电压采样模块14采集发热体R2的电压，得到发热体R2上的检测电压U 1（可以认为是电源电压）。在该时间小窗的非加热时段，控制模块11控制第一开关电路12关闭，同时，控制第二开关电路13导通，此时，电源15给参考电阻R1及发热体R2供电，控制模块11还通过电压采样模块14采集发热体R2的电压，得到发热体R2上的检测电压U2。然后，根据U 1和U 2及参考电阻R1的电阻值，通过以下公式便可计算出此时的发热体R2的电阻值：
R 2 = U 2*R 1/( U 1–U 2 )
其中，R 2 为发热体R2的电阻值，R 1为参考电阻R1的电阻值。
最后还需说明的是，在一个时间窗口内，除了最后一个时间小窗（能量补偿时间小窗），其它的每个时间小窗均可通过上面的方法计算出相应时间小窗内的发热体R2的电阻值，也就是在每个时间小窗内需要采样两次发热体R2的电压，并进行两次模数转换，如图3、图4所示。
当然，也可以仅在一个时间窗口的第一个时间小窗内，按上述方法来计算发热体R2的电阻值，如图5所示，并且，后续时间小窗的消耗能量均按照该电阻值进行计算。
下面结合图3（或图4）说明发热体R2在一个时间小窗的实际功率的计算过程：
首先，在时间窗口的n个小时间窗内，其中：
U 1t1 为在第一个时间小窗的加热时段，电压采样模块14所检测到的电压U 1；
U 2t1为在第一个时间小窗的非加热时段，电压采样模块14所检测到的电压U 2；
U 1t(n-1) 为在第n-1个时间小窗的加热时段，电压采样模块14所检测到的电压U 1；
U 2t(n-1) 为在第n-1个时间小窗的非加热时段，电压采样模块14所检测到的电压U 2；
U 1tn 为在第n个时间小窗的加热时段，电压采样模块14所检测到的电压U 1；
t 1A 为第一个时间小窗的加热时段（打开第一开关电路12及关闭第二开关电路13的时长）；
t 1B 为第一个时间小窗的非加热时段（关闭第一开关电路12及打开第二开关电路13的时长）；
t 1 为第一个时间小窗的小窗时长，即，t 1 = t 1A + t 1B；
t (n-1)A为第n-1个时间小窗的加热时段（打开第一开关电路12及关闭第二开关电路13的时长）；
t (n-1)B为第n-1个时间小窗的非加热时段（关闭第一开关电路12及打开第二开关电路13的时长）；
t n-1 为第n-1个时间小窗的小窗时长，即，t n-1 = t (n-1)A + t (n-1)B；
t nA为第n个时间小窗（能量补偿时间窗口）的加热时段（打开第一开关电路12及关闭第二开关电路13的时长）；
t nB第n个时间小窗的非加热时段（同时关闭第一开关电路12和第二开关电路13的时长）；
t n为第n个时间小窗的小窗时长，即，t n = t nA + t nB。
以第一个时间小窗为例，发热体在该时间小窗内所消耗的能量为：
P t1A = U 1t1* U 1t1/R 2 ；
P t1B = U 2t1*U 2t1/R 2 ；
E t1 = P t1A * t 1A + P t1B * t 1B
其中，P t1A为发热体在第一个时间小窗的加热时段的第一实际功率，P t2B为发热体在第一个时间小窗的非加热时段的第二实际功率，E t1为发热体在第一个时间小窗的消耗能量。
应理解，发热体在其它时间小窗内所消耗的能量的计算方法与其类似，在此不做赘述。另外，如果在某时间小窗的非加热时段未进行发热体电阻值的检测，此时，非加热时段的第二实际功率为0。
图7是本发明电子雾化装置的控制方法实施例一的流程图，该实施例的电子雾化装置的控制方法包括：
步骤S10.在当前时间窗口的第一个时间小窗的加热时段，控制发热体进行加热；
步骤S20.在当前时间窗口的第一个时间小窗的非加热时段，检测所述发热体的电阻值；

步骤S50.在当前时间窗口的最后一个时间小窗的加热时段，控制所述发热体进行加热，其中，所述最后一个时间小窗的加热时段与已运行完的时间小窗的消耗能量及消耗时间相关。

进一步地，在一个可选实施例中，当前时间窗口的各个时间小窗的加热时段相等。在另一个可选实施例中，当前时间窗口的各个时间小窗的加热时段不完全相等。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的权利要求范围之内。
