技术领域
本申请涉及电子雾化技术领域，具体涉及一种电子雾化装置及其控制电路和控制方法。
 背景技术
随着人们的健康与环保意识逐渐增强，越来越多的用户开始选择使用电子雾化装置（例如使用电子烟作为香烟的替代品），电子雾化装置的市场也越来越大，为了在激烈的市场竞争中取得优势，电子雾化装置的产品质量与生产成本均是厂家需要考虑的问题。
目前，在电子雾化装置的生产制造过程中，芯片设计生产商通常将控制芯片与PCB板及外围元器件等组装成模组进行销售，而实际的电子产品的生产商需要将该模组与电池、雾化丝以及外壳进行组装，制成完整的电子雾化装置推向市场。图1示出了相关技术中电子雾化装置的控制电路A、电池S0和雾化丝R0的连接关系示意图。如图1所示，控制电路A包括稳压电容C0、气流传感器K0以及控制芯片A0，在生产中通常需要通过在控制芯片A0的三个引脚（即VDD引脚、AT引脚和GND引脚）处焊接引线，实现控制电路A与电源S0和雾化丝R0的连接，进而实现电子雾化装置的供电及工作。
然而，由于电子雾化装置的尺寸限制，电子雾化装置的PCB板面积较小，且焊接的引线较细，并且通常需要人工进行焊接，因此若需要焊接的引线越多，则电子雾化装置的生产成本越高以及产品质量的可靠性会越低。如此，相关技术的电子雾化装置生产过程中存在生产成本较高且可靠性低的问题。

针对目前的电子雾化装置生产过程中由于需要焊接的引线较多而导致生产成本较高且可靠性低的技术问题，本申请实施例提供一种控制电路、包括该控制电路的电子雾化装置及控制电子雾化装置的方法，通过对控制电路进行优化，使得在不影响电子雾化装置使用效果的前提下，电子雾化装置的控制电路中焊接引线的数量由三根减少到两根，较大幅度缩减了生产成本，同时使得电子雾化装置的可靠性得到了保证。
下面结合附图，以具体实施例对本申请提供的控制电路、电子雾化装置及控制电子雾化装置的方法进行详细说明。需要说明的是，由于下述控制电路、电子雾化装置及控制电子雾化装置的方法基于同一构思，因此对于相同或相似的概念或过程可能在某些实施例不再赘述。
第一实施例：控制电路
图2示出了本申请一实施方式提供的控制电路的电路图。如图2所示，控制电路1包括气流传感器11、供电电容12和控制芯片13。
本申请实施例中，控制芯片13包括逻辑控制器M1、单向导通管D1和开关管K1。控制芯片13还包括电源引脚VDD（即芯片的电源脚位）、雾化引脚AT（即芯片的输出脚位）、接地引脚GND（即芯片的地脚位）。
如图2所示，逻辑控制器M1经过控制芯片13的引脚SW，连接至气流传感器11的第一端a 1。逻辑控制器M1连接至开关管K1的第一端b 1。逻辑控制器M1经过电源引脚VDD，连接至供电电容12的第一端c 1（例如电容的上极板）和开关管K1的第二端b 2。逻辑控制器M1经过接地引脚GND，连接至单向导通管D1的正极、气流传感器11的第二端a 2和供电电容12的第二端c 2（例如电容的下极板）。单向导通管D1的负极经过控制芯片13的雾化引脚AT，连接至开关管K1的第三端b 3。
其中，控制芯片13的电源引脚VDD和雾化引脚AT分别用于与外设模块（例如电源模块和雾化模块）连接，以实现电子雾化功能（以下以电子烟功能为例进行说明）。即，控制芯片用于控制电池模块和雾化模块形成电流通路以实现电子雾化功能。需要说明的是，控制芯片13与外设模块的具体连接关系将在下文中电子雾化装置的实施例中进行详细说明，此处不予赘述。
在图1所示的传统电子雾化装置的设计中，接地引脚GND需要焊接连接引线，与电池S0的负极相连，而本申请实施例提供的控制电路中，接地引脚GND处无需焊接该连接引线，从而实现了焊接引线数量由三根减少为两根的设计。
下面结合图2，通过分析控制电路中信号流在各个模块之间的流向，说明本申请实施例提供的控制电路的工作原理。
如图2所示，供电电容12和逻辑控制器M1可以形成电流通路。在形成电流通路的情况下，供电电容12可以通过放电方式，向逻辑控制器M1供电。
需要说明的是，供电电容12需要预先充电（例如由外设的电源模块进行充电），以便在供电电容12和逻辑控制器M1形成电流通路的情况下，向逻辑控制器M1供电，也就是在用户吸烟过程中，供电电容12可以为逻辑控制器M1供电。对于供电电容12的充电过程和放电过程，具体将在下文中详细描述，此处不予赘述。
再如图2所示，供电电容12、开关管K1及单向导通管D1也可以形成电流通路。在形成电流通路的情况下（即开关管K1处于导通状态），供电电容12和单向导通管D1可以形成自举电路。
可选的，本申请实施例中，供电电容12可以包括一个或多个电容，或者可以包括其他任意具有充电及放电功能的器件，具体可以根据实际使用需求确定，本申请实施例不作限定。
可选的，本申请实施例中，单向导通管D1可以包括二极管，或者可以为其他任意具有单向导通功能的器件，具体可以根据实际使用需求确定，本申请实施例不作限定。
本申请实施例中，单向导通管D1具有如下技术效果：在用户未吸烟时实现电路导通，在此情况下电池模块给供电电容12充电，并在用户吸烟过程中限制供电电容12的放电回路，在此情况下供电电容12完全为控制芯片13供电。
需要说明的是，与图1示出的相关技术控制电路中电容C0起稳压作用相比，本申请实施例中通过在控制电路中设置单向导通管D1，实现在用户吸烟时由供电电容12向控制芯片13供电的目的，从而保证了本申请实施例在将三根焊接引线改变为两根焊接引线的情况下，仍能正常实现电子雾化功能。
再参考图2，气流传感器11可以通过第二端a 2感应气流强度，然后气流传感器11可以将气流强度转换为气流强度信号，再通过第一端a 1向逻辑控制器M1输出该气流强度信号。
可以理解，在用户通过气流传感器11的第二端a 2吸烟的情况下，气流传感器11可以通过第二端a 2感应到气流强度。
本申请实施例中，在用户吸烟过程中，气流传感器11可以用于检测气流的有无和大小，并转换为电平信号输出到控制芯片13中。其中，气流传感器11还可以被称为咪头开关、气动开关或咪头感应器。
再参考图2，逻辑控制器M1用于接收气流传感器11的第一端a 1输出的气流强度信号，根据该气流强度信号控制开关管K1的通断状态，并根据气流强度信号控制开关管K1的开关频率和/或导通占空比，以调节雾化模块的功率。
其中，开关管K1的通断状态包括导通状态和截止状态。开关管K1的开关频率可以指开关管K1在一定时长内导通的次数。开关管K1的导通占空比可以指一个脉冲循环内，导通时间相对于总时间所占的比例。
示例性的，在气流强度信号的信号强度小于预设值的情况下（对应于用户未吸烟的情况），逻辑控制器M1控制开关管K1处于截止状态。以及，在气流强度信号的信号强度大于或等于该预设值的情况下（对应于用户吸烟的情况），逻辑控制器M1控制开关管K1处于导通状态。
其中，上述预设值可以根据实际情况进行设置，本申请实施例对此不作限定。
可选的，本申请实施例中，上述开关管K1可以为P型金属氧化物半导体（Metal Oxide Semiconductor, MOS）管，还可以为其他任意满足实际使用需求的晶体管，例如开关管K1可以为结型场效应管。具体可以根据实际使用需求进行设置，本申请实施例不作限定。
可以理解，在本申请实施例提供的控制电路中，开关管K1可以起开关作用。一方面，在气流强度信号的信号强度小于预设值的情况下，即在用户未吸烟的情况下，开关管K1处于截止状态，这相当于开关处于断开状态。另一方面，在气流强度信号的信号强度大于或等于预设值的情况下，即在用户吸烟的情况下，开关管K1处于导通状态，这相当于开关处于闭合状态。简而言之，逻辑控制器M1可以控制开关管K1在用户未吸烟时断开，在用户吸烟时闭合。
具体的，逻辑控制器M1用于接受气流传感器11传递的吸烟信号，并将该吸烟信号经过处理调制后驱动开关管K1，使开关管K1导通，在此情况下雾化模块中的雾化丝受热雾化烟油。
本申请实施例中，开关管K1可以为P型MOS管，或者为N型MOS管。开关管K1不同，控制电路的连接关系不同，下面分别进行说明。
第一种情况：开关管K1为P型MOS管
图3示出了开关管K1为P型MOS管情况下的控制电路的示意图。参考图3，开关管K1为P型MOS管，开关管K1的第一端b 1为栅极，第二端b 2为源极，以及第三端b 3为漏极。
示例性的，在气流强度信号的信号强度大于或等于预设值的情况下，即在用户吸烟的情况下，开关管K1处于导通状态（相当于开关闭合），开关管K1可以允许较大电流从第二端b 2（源极）流向第三端b 3（漏极）。
第二种情况：开关管K1为N型MOS管
图4示出了开关管K1为N型MOS管情况下的控制电路的示意图。参考图4，开关管K1为N型MOS管，开关管K1的第一端b 1为栅极，第二端b 2为漏极，以及第三端b 3为源极。
示例性的，在气流强度信号的信号强度大于或等于预设值的情况下，即在用户吸烟的情况下，开关管K1处于导通状态（相当于开关闭合），开关管K1可以允许较大电流从第二端b 2（漏极）流向第三端b 3（源极）。
在一种可能的实施方式中，结合图2，如图5所示，控制电路1还可以包括指示灯L1，该指示灯L1的正极经过控制芯片13的引脚LED，连接至逻辑控制器M1；该指示灯M1的负极连接至供电电容12的第二端c 2以及气流传感器11的第二端a 2。
其中，该指示灯L1可以受控制芯片13驱动，指示用户在使用电子雾化装置时的吸烟情况或状态，也可以指示电子雾化装置的电量状态，或者可以同时指示电子雾化装置的使用状态（例如吸烟状态）和电量状态，具体可以根据实际使用需求确定，本申请实施例不作限定。
可选的，本申请实施例中，指示灯L1可以用于接收逻辑控制器M1输出的驱动信号，并根据驱动信号的电压变化，采用脉宽调制PWM方式调节指示灯的亮度和/或闪灯方式。
这样，指示灯的亮度可以根据用户的吸烟力度而变化，真实地模拟了用户吸烟时香烟的点燃状态。
此外，用户可以观察指示灯的闪灯方式，获知电子雾化装置的电量是否充足。例如，若指示灯显示绿色，指示电子雾化装置当前电量充足；若指示灯显示红色，则指示电子雾化装置当前电量不足。
本申请实施例中，上述指示灯L1可以为发光二极管（Light Emitting Diode，LED），当然还可以为其他任意满足实际使用需求的发光器件，具体可以根据实际使用需求确定，本申请实施例不作限定。
本申请实施例提供的控制电路，通过对控制电路进行优化，使得在不影响电子雾化装置使用效果的前提下，控制电路原本需要连接电池负极的引线无需引出，因此焊接线的数量由三根减少到两根（省略了接地引脚GND处的引线），较大幅度地缩减了生产成本，同时使得产品的可靠性得到了保证。
第二实施例：电子雾化装置
结合图2，如图6所示，本申请实施例还提供一种电子雾化装置，该电子雾化装置包括上述第一实施例介绍的控制电路1，并且该电子雾化装置还包括电源模块2和雾化模块3。
可选的，本申请实施例中，电子雾化装置可以为加热雾化装置，例如电子烟，又例如吸入式能量棒，或者可以为其他任意可能的电子雾化装置，具体可以根据实际使用需求确定，本申请实施例不作限定。
为了便于说明和理解，下面以电子雾化装置为电子烟为例对本申请实施例提供的电子雾化装置进行示例性的说明。
本申请实施例中，上述电源模块2可以为锂电池，或者可以为其他任意满足实际使用需求的电池，具体可以根据实际使用需求确定，本申请实施例不作限定。上述雾化模块3（也称为雾化器）可以包括雾化丝（也称为负载电热丝）和烟油；在实际实现时，在雾化丝上有电流通过时，雾化丝发热，继而雾化烟油。
如图6所示，电源模块2和雾化模块3彼此连接，且均与控制电路1连接。在实际实现时，在用户吸烟的场景下，即在控制电路1中的开关管K1导通的情况下，控制电路1与电源模块2和雾化模块3可以构成电流通路，实现电子雾化功能。
在一种可能的实现方式中，如图7所示，电源模块2的正极连接至控制芯片13的电源引脚VDD，电源模块2的负极经过雾化模块3连接至控制芯片13的雾化引脚AT，且电源模块2的负极接地。
在另一种可能的实现方式中，如图8所示，电源模块2的正极经过雾化模块3连接至控制芯片13的电源引脚VDD，电源模块2的负极连接至控制芯片13的雾化引脚AT，且电源模块2的负极接地。
本申请实施例中，控制芯片的电源引脚VDD和雾化引脚AT处焊接引线，与电源模块和雾化模块连接，即可满足电子雾化装置使用需求。与现有技术相比，本申请实施例提供的电子雾化装置中无需在控制芯片的接地引脚GND与电池模块之间焊接引线。
需要说明的是，上述控制电路1与电源模块2和雾化模块3的连接关系均为示例性的列举，可以理解，在实际实现时，本申请实施例提供的电子雾化装置还可以包括其他可能的实施方式，例如可以根据开关管的具体选用，来确定在实际生产中控制电路1与电源模块2和雾化模块3的连接关系，具体可以根据实际使用需求确定，本申请实施例不作限定。
本申请实施例提供的电子雾化装置可以通过采用两根焊接引线连接电子雾化装置的控制电路与电池模块和雾化模块，实现电子雾化功能。与相关技术采用三根焊接引线相比，本申请提供的电子雾化装置中焊接引线的数量由三根减少到两根，在保证电子雾化装置的可靠性的同时，较大幅度缩减了生产成本。
下面分别针对用户未吸烟场景和吸烟场景，描述电子雾化装置中形成的电路通路。
用户未吸烟场景：在气流强度信号的信号强度小于预设值的情况下，即在用户未吸烟（或停止吸烟）的情况下，开关管K1处于截止状态（相当于开关断开），电源模块2、雾化模块3和开关管K1不会形成电流通路。在用户未吸烟的情况下，电源模块2、雾化模块3、供电电容12和单向导通管D1形成第一电流通路，电源模块2向供电电容12充电。此外，在用户未吸烟的情况下，电源模块2、雾化模块3、逻辑控制器M1和单向导通管D1形成第二电流通路，电源模块2向逻辑控制器M1供电。
用户吸烟场景：在气流强度信号的信号强度大于或等于预设值的情况下，即在用户吸烟的情况下，开关管K1处于导通状态（相当于开关闭合），开关管K1可以允许较大电流从第二端b 2流向第三端b 3。在用户吸烟的情况下，电源模块2、雾化模块3和开关管K1形成第三电流通路，雾化模块3根据开关管K1的开关频率和/或导通占空比，调节烟油雾化量。此外，在用户吸烟的情况下，逻辑控制器M1和供电电容12形成第四电流通路，供电电容12向逻辑控制器M1供电。
具体而言，在用户吸烟的情况下，供电电容12向逻辑控制器M1供电，逻辑控制器M1接受气流传感器11传递的吸烟信号，经过处理调制后驱动开关管K1，使开关管K1导通，电池模块2的电压施加在雾化模块3的两端，在此情况下雾化模块3中的雾化丝受热雾化烟油。
本申请实施例中，在控制电路1中采用不同开关管的情况下，控制电路1与电源模块2和雾化模块3的连接关系可以包括多种可能的实施方式。下面结合附图，通过下述的第一实施方式（其中开关管K1为P型MOS管）和第二实施方式（其中开关管K1为N型MOS管），描述在电池模块2、雾化模块3与上述控制电路1连接的情况下，电子雾化装置的具体连接关系及工作原理。
方式一：开关管K1为P型MOS管
控制电路1中的开关管K1为P型MOS管；其中，开关管（K1）的第一端b 1为栅极（用G标记），第二端b 2为源极（用S标记），以及第三端b 3为漏极（用D标记）。
图9示出了本申请提供的控制电路中采用P型MOS管时，电子雾化装置的一种电路连接示意图。如图9所示，开关管K1的栅极G连接至逻辑控制器M1。开关管K1的源极S经过控制芯片13的电源引脚VDD，连接至电源模块2的正极。开关管K1的漏极D经过控制芯片13的雾化引脚AT且经过雾化模块3，连接至电源模块2的负极。并且，电源模块2的负极接地。
此外，对于开关管K1为P型MOS管的情况，电子雾化装置还包括下述的电路连接关系（图中未示出）：开关管K1的栅极连接至逻辑控制器M1；开关管K1的源极经过控制芯片13的电源引脚VDD且经过雾化模块3，连接至电源模块2的正极；开关管K1的漏极经过控制芯片13的雾化引脚AT，连接至电源模块2的负极；并且，电源模块2的负极接地。
下面结合图9，以开关管K1为P型MOS管为例，总体上描述在电池模块2、雾化模块3与上述控制电路1连接的情况下，电子雾化装置的工作过程。
（1）在用户未吸烟的状态下，电池模块2的正极连接至供电电容12的上极板，供电电容12的下极板经过单向导通管D1和雾化模块3连接至电池模块2的负极上，从而电池模块2给供电电容12充电。其中，供电电容12的上下极板之间的电压差近似等于电池模块2的电压值。需要说明的是，在此情况下雾化模块3中的雾化丝作为导线，不会雾化烟油。同时，电池模块2为控制电路1中的逻辑控制器M1供电，周期性地检测气流传感器11上的信号情况，等待用户吸烟动作的指令。
（2）在用户吸烟时，气流传感器11检测到气流，并将其转换为电平信号传递到控制芯片13内的逻辑控制器M1中，该逻辑控制器M1控制开关管K1闭合，此时电池模块2与雾化模块3形成电流回路，雾化模块3开始发热并雾化烟油，形成雾化效果。在此过程中，逻辑控制器M1可以根据用户吸烟的力度通过PWM调节的方式，控制雾化模块中雾化丝的通断时间，以调节烟油雾化量。
尽管此时电池模块2此时无法继续为控制芯片13中的逻辑控制器M1供电，但是由于二极管D1的存在，在开关管K1闭合后，供电电容12的上下极板之间的电势差仍等于电池的电压，此时供电电容12接替电池模块2为控制芯13中的逻辑控制器M1供电，维持吸烟过程中逻辑控制器M1的正常功能。
（3）在用户结束吸烟动作后，开关管K1断开，此时电池模块2重新为逻辑控制器M1供电，同时重新给供电电容12充电，此充电过程非常迅速，即使用户两次吸烟动作时间间隔短暂，也可以保证供电电容12充电完成。
由此，本申请实施例可以实现在控制电路（即控制芯片）焊接引线数量从三线减少为两线之后电子雾化装置的正常供电及工作。
方式二：开关管K1为N型MOS管
控制电路1中的开关管K1为N型MOS管；其中，开关管（K1）的第一端b 1为栅极G，第二端b 2为漏极D，以及第三端b 3为源极S。
图10示出了本申请提供的控制电路中采用N型MOS管时，电子雾化装置的电路连接示意图。如图10所示，开关管K1的栅极G连接至逻辑控制器M1。开关管K1的漏极D经过控制芯片13的电源引脚VDD且经过雾化模块3，连接至电源模块2的正极。开关管K1的源极S经过控制芯片13的雾化引脚AT，连接至电源模块2的负极。并且，电源模块2的负极接地。
此外，对于开关管K1为N型MOS管的情况，电子雾化装置还包括下述的电路连接关系：开关管K1的栅极G连接至逻辑控制器M1；开关管K1的漏极D源极S经过控制芯片13的电源引脚VDD，直接连接至电源模块2的正极；开关管K1的源极S经过控制芯片13的雾化引脚AT且经过雾化模块3，连接至电源模块2的负极；并且，电源模块2的负极接地。
在方式二中，在用户未吸烟时、在用户吸烟时以及在用户结束吸烟动作后，电子雾化装置的工作过程可以参见上述方式一中的详细描述，此处不予赘述。
在一种可能的实施方式中，本申请实施例提供的电子雾化装置还可以包括开关模块，该开关模块用于根据用户对开关模块的操作指令，控制电子雾化装置在启用状态和禁用状态之间进行切换。
示例性的，结合图7，如图11所示，电子雾化装置还包括开关模块4，其设置于控制芯片13的电源引脚VDD与电源2的正极之间。
当然，开关模块还可以设置于电子雾化装置中其他任意满足实际使用需求的位置，具体可以根据实际使用需求确定，本申请实施例不作限定。
可选的，本申请实施例中，上述开关模块可以为按键开关，也可以为触摸式开关，或者嘴唇感应开关，还可以为其他任意满足实际使用需求的开关，具体可以根据实际使用需求确定，本申请实施例不作限定。
示例性的，以开关模块为触摸式开关为例，若用户想要吸烟，则用户可以先触摸电子雾化装置上的触摸式开关，以触发电子雾化功能开启，然后用户可以通过电子雾化装置实现吸烟目的。进一步的，若用户不吸烟，则用户可以再次触摸电子雾化装置上的触摸式开关，以触发电子雾化功能关闭。或者，在检测到用户未吸烟的动作持续时长达到预设时长的情况下，电子雾化装置可以自动关闭。如此，可以保证电子雾化装置的使用安全性。
在一种可能的实施方式中，本申请实施例提供的电子雾化装置还包括壳体和电控板。其中，控制电路1设置于电控板上，该电控板容置于该壳体内。
本申请实施例中，可以保证电子雾化装置正常工作与控制的前提下，电子雾化装置的控制芯片不需要与电池的两极同时直接相连，即控制芯片的GND脚位无需焊接引线，由此需要引出的焊接引线数量由三线减少为两线，既可以优化PCB的布局设计，又可以减少由于焊线带来的生产成本，同时可以有效地规避人工操作带来的失效风险。
需要说明的是，本申请上述实施例中的各个附图（例如图7、图8等）均是结合上述图2示例说明的，具体实现时，各个附图还可以结合其它任意可以结合的附图实现，例如图7和图8还可以结合图5实现。
以上介绍了一种电子雾化装置及其控制电路，其中控制芯片不需要与电池的两极同时直接相连，即控制芯片的GND脚位无需焊接引线，由此需要引出的焊接引线数量由三线减少为两线；下面再介绍另一种电子雾化装置及其控制电路，其中那个控制电路不需要与电池的两极同时直接相连，即控制芯片的电源引脚VDD处无需焊接引线，由此需要引出的焊接引线数量由三线减少为两线。这两种电子雾化装置及其控制电路均具有如下有益效果：既可以优化PCB的布局设计，又可以减少由于焊线带来的生产成本，同时可以有效地规避人工操作带来的失效风险。
第三实施例：控制电路
图12示出了本申请一实施方式提供的控制电路的电路图。如图12所示，控制电路1包括气流传感器11、供电电容12和控制芯片13。
本申请实施例中，控制芯片13包括逻辑控制器M1、单向导通管D1和开关管K1。控制芯片13还包括电源引脚VDD（即芯片的电源脚位）、雾化引脚AT（即芯片的输出脚位）、接地引脚GND（即芯片的地脚位）。
如图12所示，逻辑控制器M1经过控制芯片13的引脚SW，连接至气流传感器11的第一端a 1。逻辑控制器M1连接至开关管K1的第一端b 1。逻辑控制器M1经过电源引脚VDD，连接至供电电容12的第一端c 1（例如电容的上极板）和单向导通管D1的负极。单向导通管D1的正极经过雾化引脚AT，连接至开关管K1的第二端b 2。逻辑控制器M1经过接地引脚GND，连接至开关管K1的第三端b 3、气流传感器11的第二端a 2和供电电容12的第二端c 2（例如电容的下极板）。
其中，控制芯片13的雾化引脚AT和接地引脚GND分别用于与外设模块（例如电源模块和雾化模块）连接，以实现电子雾化功能（以下以电子烟功能为例进行说明）。即，控制芯片用于控制电池模块和雾化模块形成电流通路以实现电子雾化功能。需要说明的是，控制芯片13与外设模块的具体连接关系将在下文中电子雾化装置的实施例中进行详细说明，此处不予赘述。
在图1所示的传统电子雾化装置的设计中，电源引脚VDD需要焊接连接引线，与电池S0的正极相连，而本申请实施例提供的控制电路中，电源引脚VDD处无需焊接该连接引线，从而实现了焊接引线数量由三根减少为两根的设计。
需要说明的是，图12中控制电路中的各个器件（例如气流传感器11、供电电容12、逻辑控制器M1、开关管K1、单向导通管D1）的工作性能、作用以各个器件之间的信号流交互原理类似于图2中控制电路中的各个器件的工作性能、作用以及各个器件之间的信号流交互原理，因此对于各个器件的描述不再赘述。
可选的，本申请实施例中，上述开关管K1可以为MOS管，还可以为其他任意满足实际使用需求的晶体管，例如开关管K1可以为结型场效应管。具体可以根据实际使用需求进行设置，本申请实施例不作限定。
可以理解，在本申请实施例提供的控制电路中，开关管K1可以起开关作用。一方面，在气流强度信号的信号强度小于预设值的情况下，即在用户未吸烟的情况下，开关管K1处于截止状态，这相当于开关处于断开状态。另一方面，在气流强度信号的信号强度大于或等于预设值的情况下，即在用户吸烟的情况下，开关管K1处于导通状态，这相当于开关处于闭合状态。简而言之，逻辑控制器M1可以控制开关管K1在用户未吸烟时断开，在用户吸烟时闭合。
具体的，逻辑控制器M1用于接受气流传感器11传递的吸烟信号，并将该吸烟信号经过处理调制后驱动开关管K1，使开关管K1导通，在此情况下雾化模块3中的雾化丝受热雾化烟油。
本申请实施例中，开关管K1可以为P型MOS管，或者为N型MOS管。开关管K1不同，控制电路的连接关系不同，下面分别进行说明。
图13示出了开关管K1为P型MOS管情况下的控制电路的示意图。参考图13，开关管K1为P型MOS管，开关管K1的第一端b 1为栅极，第二端b 2为源极，以及第三端b 3为漏极。示例性的，在气流强度信号的信号强度大于或等于预设值的情况下，即在用户吸烟的情况下，开关管K1处于导通状态（相当于开关闭合），开关管K1可以允许较大电流从第二端b 2（源极）流向第三端b 3（漏极）。
图14示出了开关管K1为N型MOS管情况下的控制电路的示意图。参考图14，开关管K1为N型MOS管，开关管K1的第一端b 1为栅极，第二端b 2为漏极，以及第三端b 3为源极。示例性的，在气流强度信号的信号强度大于或等于预设值的情况下，即在用户吸烟的情况下，开关管K1处于导通状态（相当于开关闭合），开关管K1可以允许较大电流从第二端b 2（漏极）流向第三端b 3（源极）。
在一种可能的实施方式中，结合图12，如图15所示，控制电路1还可以包括指示灯L1，该指示灯L1的正极经过控制芯片13的引脚LED，连接至逻辑控制器M1；该指示灯M1的负极连接至供电电容12的第二端c 2以及气流传感器11的第二端a 2。
需要说明的是，图15中的指示灯L1的工作特性和作用类似于上述图5中指示灯L1的工作特性和作用，因此对于指示灯L1的描述可以参考上述图5中指示灯L1的描述，次数不再赘述。
本申请实施例提供的控制电路，通过对控制电路进行优化，使得在不影响电子雾化装置使用效果的前提下，控制电路原本需要连接电池正极的引线无需引出，因此焊接线的数量由三根减少到两根（省略了电源引脚VDD处的引线），较大幅度地缩减了生产成本，同时使得产品的可靠性得到了保证。
第四实施例：控制电路
结合图12，如图16所示，本申请实施例还提供一种电子雾化装置，该电子雾化装置包括上述第三实施例介绍的控制电路1，并且该电子雾化装置还包括电源模块2和雾化模块3。
可选的，本申请实施例中，电子雾化装置可以为加热雾化装置，例如电子烟，又例如吸入式能量棒，或者可以为其他任意可能的电子雾化装置，具体可以根据实际使用需求确定，本申请实施例不作限定。
为了便于说明和理解，下面以电子雾化装置为电子烟为例对本申请实施例提供的电子雾化装置进行示例性的说明。
本申请实施例中，上述电源模块2可以为锂电池，或者可以为其他任意满足实际使用需求的电池，具体可以根据实际使用需求确定，本申请实施例不作限定。上述雾化模块3（也称为雾化器）可以包括雾化丝（也称为负载电热丝）和烟油；在实际实现时，在雾化丝上有电流通过时，雾化丝发热，继而雾化烟油。
如图16所示，电源模块2和雾化模块3彼此连接，且均与控制电路1连接。在实际实现时，在用户吸烟的场景下，即在控制电路1中的开关管K1导通的情况下，控制电路1与电源模块2和雾化模块3可以构成电流通路，实现电子雾化功能。
在一种可能的实现方式中，如图17所示，电源模块2的正极经过雾化模块3连接至控制芯片13的雾化引脚AT，电源模块2的负极连接至控制芯片13的接地引脚GND，且电源模块2的负极接地。
在另一种可能的实现方式中，如图18所示，电源模块2的正极连接至控制芯片13的雾化引脚AT，电源模块2的负极经过雾化模块3连接至控制芯片13的接地引脚GND，且电源模块2的负极接地。
本申请实施例中，控制芯片的接地引脚GND和雾化引脚AT处焊接引线，与电源模块和雾化模块连接，即可满足电子雾化装置使用需求。与现有技术相比，本申请实施例提供的电子雾化装置中无需在控制芯片的电源引脚VDD与电池模块之间焊接引线。
需要说明的是，上述控制电路1与电源模块2和雾化模块3的连接关系均为示例性的列举，可以理解，在实际实现时，本申请实施例提供的电子雾化装置还可以包括其他可能的实施方式，例如可以根据开关管的具体选用，来确定在实际生产中控制电路1与电源模块2和雾化模块3的连接关系，具体可以根据实际使用需求确定，本申请实施例不作限定。
本申请实施例提供的电子雾化装置可以通过采用两根焊接引线连接电子雾化装置的控制电路与外设的电池模块和雾化模块，实现电子雾化功能。与相关技术采用三根焊接引线相比，本申请提供的电子雾化装置中焊接引线的数量由三根减少到两根，在保证电子雾化装置的可靠性的同时，较大幅度缩减了生产成本。
下面分别针对用户未吸烟场景和吸烟场景，描述电子雾化装置中形成的电路通路。
用户未吸烟场景：在气流强度信号的信号强度小于预设值的情况下，即在用户未吸烟（或停止吸烟）的情况下，开关管K1处于截止状态（相当于开关断开），电源模块2、雾化模块3和开关管K1不会形成电流通路。在用户未吸烟的情况下，电源模块2、雾化模块3、供电电容12和单向导通管D1形成第一电流通路，电源模块2向供电电容12充电。此外，在用户未吸烟的情况下，电源模块2、雾化模块3、逻辑控制器M1和单向导通管D1形成第二电流通路，电源模块2向逻辑控制器M1供电。
用户吸烟场景：在气流强度信号的信号强度大于或等于预设值的情况下，即在用户吸烟的情况下，开关管K1处于导通状态（相当于开关闭合），开关管K1可以允许较大电流从第二端b 2流向第三端b 3。在用户吸烟的情况下，电源模块2、雾化模块3和开关管K1形成第三电流通路，雾化模块3根据开关管K1的开关频率和/或导通占空比，调节烟油雾化量。此外，在用户吸烟的情况下，逻辑控制器M1和供电电容12形成第四电流通路，供电电容12向逻辑控制器M1供电。
具体而言，在用户吸烟的情况下，供电电容12向逻辑控制器M1供电，逻辑控制器M1接收气流传感器11传递的吸烟信号，经过处理调制后驱动开关管K1，使开关管K1导通，电池模块2的电压施加在雾化模块3的两端，在此情况下雾化模块3中的雾化丝受热雾化烟油。
本申请实施例中，在控制电路1中采用不同开关管的情况下，控制电路1与电源模块2和雾化模块3的连接关系可以包括多种可能的实施方式。下面结合附图，通过下述的第一实施方式（其中开关管K1为P型MOS管）和第二实施方式（其中开关管K1为N型MOS管），描述在电池模块2、雾化模块3与上述控制电路1连接的情况下，电子雾化装置的具体连接关系及工作原理。
第一方式：开关管K1为P型MOS管
控制电路1中的开关管K1为P型MOS管；其中，开关管（K1）的第一端b 1为栅极（以G标记），第二端b 2为源极（以S标记），以及第三端b 3为漏极（以D标记）。
图19示出了本申请提供的控制电路中采用P型MOS管时，电子雾化装置的一种可能的电路连接示意图。如图19所示，开关管K1的栅极G连接至逻辑控制器M1。开关管K1的源极S经过控制芯片13的雾化引脚AT且经过雾化模块3，连接至电源模块2的正极。开关管K1的漏极D经过控制芯片13的接地引脚GND，连接至电源模块2的负极。并且，电源模块2的负极接地。
此外，对于开关管K1为P型MOS管的情况，电子雾化装置还可以包括下述的电路连接关系（图中未示出）：开关管K1的栅极G连接至逻辑控制器M1；开关管K1的源极S经过控制芯片13的雾化引脚AT，直接连接至电源模块2的正极；开关管K1的漏极D经过控制芯片13的接地引脚GND且经过雾化模块3，连接至电源模块2的负极；并且，电源模块2的负极接地。
下面结合图19，以开关管K1为P型MOS管为例，总体上描述在电池模块2、雾化模块3与上述控制电路1连接的情况下，电子雾化装置的工作过程。

同时，电池模块2为控制电路1中的逻辑控制器M1供电，周期性地检测气流传感器11上的信号情况，等待用户吸烟动作的指令。
（2）在用户吸烟时，气流传感器11检测到气流，并将其转换为电平信号传递到控制芯片13内的逻辑控制器M1中，该逻辑控制器M1控制开关管K1闭合，此时电池模块2与雾化模块3形成电流回路，雾化模块3开始发热并雾化烟油，形成雾化效果。在此过程中，逻辑控制器M1可以根据用户吸烟的力度通过PWM调节的方式，控制雾化丝的通断时间，以调节烟油雾化量。
尽管此时电池模块2此时无法继续为控制芯片13中的逻辑控制器M1供电，但是由于二极管D1的存在，在开关管K1闭合后，供电电容12的上下极板之间的电势差仍等于电池的电压，此时供电电容12接替电池模块2为控制芯13中的逻辑控制器M1供电，维持吸烟过程中逻辑控制器M1的正常功能。
（3）在用户结束吸烟动作后，开关管K1断开，此时电池模块2重新为逻辑控制器M1供电，同时重新给供电电容12充电，此充电过程非常迅速，即使用户两次吸烟动作时间间隔短暂，也可以保证供电电容12充电完成。
由此，本申请实施例可以实现在控制芯片的焊接引线数量从三线减少为两线之后电子雾化装置的正常供电及工作。
第二方式：开关管K1为N型MOS管
控制电路1中的开关管K1为N型MOS管；其中，开关管（K1）的第一端b 1为栅极G，第二端b 2为漏极D，以及第三端b 3为源极S。
图20示出了本申请提供的控制电路中采用N型MOS管时，电子雾化装置的一种可能的电路连接示意图。如图20所示，开关管K1的栅极G连接至逻辑控制器M1。开关管K1的漏极D经过控制芯片13的雾化引脚AT，直接连接至电源模块2的正极。开关管K1的源极S经过控制芯片13的接地引脚GND且经过雾化模块3，连接至电源模块2的负极。并且，电源模块2的负极接地。
此外，对于开关管K1为N型MOS管的情况，电子雾化装置还可以包括下述的电路连接关系（图中未示出）：开关管K1的栅极G连接至逻辑控制器M1；开关管K1的漏极D经过控制芯片13的雾化引脚AT且经过雾化模块3，连接至电源模块2的正极；开关管K1的源极S经过控制芯片13的接地引脚GND，直接连接至电源模块2的负极；并且，电源模块2的负极接地。
在第二方式中，在用户未吸烟时、在用户吸烟时以及在用户结束吸烟动作后，电子雾化装置的工作过程可以参见上述第一方式中的详细描述，此处不予赘述。
在一种可能的实施方式中，本申请实施例提供的电子雾化装置还可以包括开关模块，该开关模块用于根据用户对开关模块的操作指令，控制电子雾化装置在启用状态和禁用状态之间进行切换。
示例性的，结合图17，如图21所示，电子雾化装置还包括开关模块4，其设置于控制芯片13的接地引脚GND与电源2的负极之间。
当然，开关模块还可以设置于电子雾化装置中其他任意满足实际使用需求的位置，具体可以根据实际使用需求确定，本申请实施例不作限定。
可选的，本申请实施例中，上述开关模块可以为按键开关，也可以为触摸式开关，或者嘴唇感应开关，还可以为其他任意满足实际使用需求的开关，具体可以根据实际使用需求确定，本申请实施例不作限定。
示例性的，以开关模块为触摸式开关为例，若用户想要吸烟，则用户可以先触摸电子雾化装置上的触摸式开关，以触发电子雾化功能开启，然后用户可以通过电子雾化装置实现吸烟目的。进一步的，若用户不吸烟，则用户可以再次触摸电子雾化装置上的触摸式开关，以触发电子雾化功能关闭。或者，在检测到用户未吸烟的动作持续时长达到预设时长的情况下，电子雾化装置可以自动关闭。如此，可以保证电子雾化装置的使用安全性。
在一种可能的实施方式中，本申请实施例提供的电子雾化装置还包括壳体和电控板。其中，控制电路1设置于电控板上，该电控板容置于该壳体内。
本申请实施例中，可以保证电子雾化装置正常工作与控制的前提下，电子雾化装置的控制电路不需要与电池的两极同时直接相连，即控制芯片的电源引脚VDD处无需焊接引线，由此需要引出的焊接引线数量由三线减少为两线，既可以优化PCB的布局设计，又可以减少由于焊线带来的生产成本，同时可以有效地规避人工操作带来的失效风险。

本申请实施例中，在开关管处于截止状态的情况下，即用户未吸烟（或停止吸烟）的情况下，电子雾化装置中的电池不但可以向电容充电，而且还可以向逻辑控制器供电，从而逻辑控制器可以周期性地检测用户吸烟动作的指令。并且，在开关管处于导通状态的情况下，即用户吸烟的情况下，电容会向逻辑控制器放电，并且此时电子雾化装置中的雾化器进行烟油雾化。
本申请实施例提供的控制电子雾化装置的方法，应用于上述改进后的电子雾化装置（即采用两根焊接引线），可以实现在用户未吸烟状态下由电池为供电电容充电，以及在用户吸烟状态下由供电电容为电子雾化装置供电，并实现烟油雾化功能。与相关技术中采用三根焊接引线并采用电池向逻辑控制器供电的方案相比，本申请实施例可以降低生产成本、提高产品可靠性。

S101B、在气流强度信号的信号强度大于或等于预设值的情况下，逻辑控制器控制开关管处于导通状态。
若气流强度信号的信号强度大于或等于预设值，则表示用户正在吸烟，此时，控制开关管处于导通状态，进一步的，电子雾化装置中的电容向逻辑控制器供电，电子雾化装置中的雾化器受热后进行烟油雾化，实现电子雾化功能。
