本申请实施例提供一种用于气溶胶发生系统的无线充电电路。
所述无线充电电路包括：
气溶胶发生模组，包括第一感应线圈，通过所述第一感应线圈电磁感应接收电源，所述气溶胶发生模组的输出端输出为电池充电，所述气溶胶发生模组还包括第一电容与谐振控制开关以及调节电容，所述第一电容与所述第一感应线圈组成谐振回路，所述谐振控制开关与所述调节电容组成谐振参数调节单元，所述谐振参数调节单元与所述第一感应线圈组成的谐振回路连接；
充电模组，包括变压器、第二电容以及第二感应线圈，所述变压器将市电电压转换为工作电压，所述第二电容以及所述第二感应线圈组成谐振回路，所述变压器与所述第二感应线圈组成的谐振回路连接，其中，所述第一感应线圈与所述第二感应线圈电磁感应；
控制模组，所述控制模组的输出连接所述谐振控制开关的控制端，由所述控制模组控制所述谐振控制开关的开断进而调节所述第一感应线圈组成的谐振回路的谐振参数。
气溶胶发生模组，还可以用于接收电池的供电，对气溶胶基质进行加热，以产生气溶胶。
下面以第一电容与第一感应线圈串联连接，第二电容与第二感应线圈串联连接，分别组成串联的谐振回路为例，进行说明。可以理解的是，谐振回路中，电容也可以和感应线圈并联连接，组成并联的谐振回路。
通过由充电模组对输入的市电电压进行降压，气溶胶发生模组中的第一感应线圈结合充电模组中的第二感应线圈进行电磁感应充电，使得降压后的工作电压从充电模组中的第二感应线圈电磁感应传输至气溶胶发生模组中的第一感应线圈，使得第一感应线圈产生感应电流，控制模组控制谐振控制开关关断，电流能够流经至电池进行充电；当电池充满电时，控制模组获得电池充满电的信号，控制谐振控制开关导通，可以将调节电容并联接入到第一感应线圈组成的谐振回路中，进而使得第一感应线圈所组成的谐振回路的谐振频率变小，回路呈现容性阻抗，致其回路中充电电流变小，从而充电模组内的谐振回路的谐振电流同时减小，实现控制谐振控制开关的间歇性导通关断而改变第一感应线圈所处的谐振参数，实现电池充满电时对充电模组的反馈，从而降低第二感应线圈的谐振电流，达到降低功耗，节约电能。
当然，调节电容也可以与第一感应线圈串联连接，此时，谐振控制开关与调节电容并联。当谐振控制开关截止时，调节电容接入到第一感应线圈组成的谐振回路中。当谐振控制开关导通时，调节电容未接入到第一感应线圈组成的谐振回路中。因此，谐振控制开关导通前后，第一感应线圈所组成的谐振回路中，电容大小可以得到改变，进而实现其所属谐振回路的谐振参数的调节。
可以理解的是，谐振控制开关与调节电容的连接形式，以及谐振控制开关的导通截止的控制方式，可以根据第一感应线圈与第一电容组成谐振回路的形式不同，而具体适配。只要谐振控制开关的导通和截止两种状态中，可以改变第一感应线圈所组成的谐振回路中的电容的大小即可。

通过由充电模组对输入的市电电压进行降压，气溶胶发生模组中的第一感应线圈L1结合充电模组中的第二感应线圈L2进行电磁感应充电，使得降压后的工作电压从充电模组中的第二感应线圈L2电磁感应传输至气溶胶发生模组中的第一感应线圈L1，使得气溶胶发生模组中的电流增大，控制模组控制谐振控制开关Q5关断，电流能够流经至电池进行充电，反之，当电池充满电时，控制模组获得电池充满电的信号，控制谐振控制开关Q5导通，从而调节电容C3与第一感应线圈L1并联,进而使得第一感应线圈L1所构成的谐振回路的谐振频率变小，回路呈现容性阻抗，致其回路中充电电流变小，从而充电模组内的流经第二感应线圈的谐振电流同时减小。
在本实施例中，控制模组可以具体包括气溶胶发生模组的控制模块与充电模组的控制模块，气溶胶发生模组的控制模块控制气溶胶发生模组中的元器件，充电模组的控制模块控制充电模组中的元器件。
气溶胶发生模组的第一感应线圈L1可以呈竖形螺旋状，其中，第一感应线圈L1可以围绕着气溶胶发生模组螺旋上升。第一感应线圈L1也可以是平面螺旋状。利用第一感应线圈L1与第二感应线圈L2之间互感，使得充电模组内的电能转化成磁能传递至气溶胶发生模组的第一感应线圈L1，气溶胶发生模组的第一感应线圈L1再把磁能转化成电能，储存至电池，完成充电。在第二感应线圈L2的外围，可以增加隔磁片以聚集磁能，使第二感应线圈L2至气溶胶发生模组的第一感应线圈L1的能量的转化效率提升。在本实施例中，气溶胶发生模组的第一感应线圈L1的圈数为9-10圈，线径1.2mm，内含单股外表绝缘铜丝，共约200股左右，电感量在10微亨至10亨左右，绕线直径为15mm左右。充电模组的第二感应线圈L2的圈数大于第一感应线圈L1的圈数，其中，充电模组的第二感应线圈L2的圈数以13-14圈为主，线径1.2mm，内含单股外表绝缘铜丝，共约200股左右，电感量在10微亨至10亨左右，绕线直径为25mm左右。
在本实施例中，所述气溶胶发生模组还可以包括第一场效应晶体管Q1与第二场效应晶体管Q2，其中，所述第一场效应晶体管Q1的源极与所述第二场效应晶体管Q2的漏极连接，并与所述第一电容C1连接；所述第二场效应晶体管Q2的源极接地，并与所述第一感应线圈L1连接；所述第一场效应晶体管Q1的漏极连接电池，所述第一场效应晶体管Q1的栅极与所述第二场效应晶体管Q2的栅极分别连接所述气溶胶发生模组的控制模块；气溶胶发生模组的控制模块分别连接第一场效应晶体管Q1的栅极与第二场效应晶体管Q2的栅极以及谐振控制开关Q5的基极，进而由气溶胶发生模组的控制模块控制第一场效应晶体管Q1与第二场 效应晶体管Q2以及谐振控制开关Q5关断，其中，通过控制所述谐振控制开关Q5的开断进而调节所述第一感应线圈组成的谐振回路的谐振参数。
气溶胶发生模组可以具有加热工作模式和无线充电模式，分别用于加热气溶胶基质和无线充电。第一场效应晶体管Q1、第二场效应晶体管Q2、第一感应线圈L1以及第一电容C1组成半桥谐振电磁加热电路。在无线充电模式中对电池进行供电，通过气溶胶发生模组的控制模块对第一场效应晶体管Q1、第二场效应晶体管Q2截止与导通的控制，可以实现对气溶胶基质的加热。在半桥谐振电磁加热电路的基础上，通过增加调节电容C3以及谐振控制开关Q5，配合气溶胶发生模组的控制模块对第一场效应晶体管Q1、第二场效应晶体管Q2截止与导通的控制，可以实现对电池的无线充电。通过复用第一感应线圈L1以及半桥谐振电磁加热电路来构建无线充电电路，可以减少元器件的使用数量，降低成本，减小尺寸；还能减少充电接口的设置，便于气溶胶发生装置进行防水防尘的设计。
示例的，第一感应线圈L1以及第一电容C1组成的谐振回路的谐振频率可以为200Khz。当气溶胶发生模组处于加热工作模式时，气溶胶发生模组的控制模块可以向第一场效应晶体管Q1与第二场效应晶体管Q2的栅极提供200Khz频率的互补的PWM脉冲控制信号，让第一场效应晶体管Q1与第二场效应晶体管Q2进行200Khz频率互补导通，产生高速变化的高频电流流过第一感应线圈L1，以产生高速变化的交变磁场。发热体置于交变磁场中，可以感应产生涡流而发热，进而加热气溶胶基质，产生气溶胶。可以理解的是，第一感应线圈L1以及第一电容C1组成的谐振回路的谐振频率也可以为其他数值。
发热体可以采用任意可以在交变磁场中产生感应电流的材质，最常见的为金属，比如铁。可以理解的是，发热体可以作为气溶胶发生装置的一个部件，可以设置于第一感应线圈L1的中心位置。发热体也可以不属于气溶胶发生装置，而内置于气溶胶基质中；当将气溶胶基质插入于气溶胶发生装置内时，发热体位于第一感应线圈L1的中心位置。
当气溶胶发生装置插入充电座，气溶胶发生装置处于无线充电模式时，第二感应线圈L2的交流电压感应至第一感应线圈L1，感应电流通过第一场效应晶体管Q1、第二场效应晶体管Q2整流后输出至电池VBAT，完成无线充电。其中，第二感应线圈L2的谐振电流可以配置得较低(比如，无线充电模式下谐振电流可以为500mA，而让发热体正常发热工作时流经第一感应线圈的电流一般为1A-4A)，其感应涡流能量就不足以让发热体产生太多的热量。
在本实施例中，为了降低无线充电时发热体受到磁感应发热的温度，降低由此带来的电能浪费的问题，可以在充电座中心位置处可以设置一个隔磁环，当气溶胶发生装置插入到充电座时，发热体插入到隔磁环中，因而发热体就不会受到无线充电的磁场的影响。
在其他实施例中，为了减少无线充电时发热体感应发热带来的电能损耗，还可以让气溶胶发生装置加热工作模式时的第一感应线圈L1的工作频率，不等于无线充电时的第一感应线圈L1工作频率，甚至，二者之间可以相差较大。
当然，在另一实施例中，第一感应线圈L1、第二场效应晶体管Q2以及第一电容C1相互并联并接入第一场效应晶体管Q1的源极，其中，第一感应线圈L1与第一电容C1组成并联谐振电路。
充电过程：第一感应线圈L1上的感应电流(即充电电流)可以具有正半周期和负半周期。当感应电流为正半周期时(以第一感应线圈L1上的电流方向朝上为例)，气溶胶发生模组的控制模块控制第一场效应晶体管Q1导通，并截止第二场效应晶体管Q2，感应电流经第一电容C1、第一场效应晶体管Q1，给电池进行充电。当感应电流为负半周期时(以第一感应线圈L1上的电流方向朝下为例)，控制第一场效应晶体管Q1截止，并导通第二场效应晶体管Q2，感应电流经第二场效应晶体管Q2，并与第一电容C1形成回路。
在本实施例中，所述气溶胶发生模组还包括第一电阻R1，所述第一电阻R1连接于所述谐振控制开关Q5的控制端。第一电阻R1主要是限定所述谐振控制开关Q5的源极与控制模块之间的电流的大小。调节电容C3的一端连接于所述谐振控制开关Q5的集电极，所述谐振控制开关Q5的发射极接地，第一感应线圈L1的一端连接与调节电容C3的另一端，第一感应线圈的L1的另一端连接于谐振控制开关Q5的发射极。
具体地，相对于原来的电磁加热的电路，本申请回路多了第一电阻R1、调节电容C3、谐振控制开关Q5组成的谐振参数调节单元。在加热时，或者无线充电过程中、且电池未充满电时，谐振控制开关Q5截止。当气溶胶发生装置内的控制模块检测到电池充满时，通过谐振控制开关Q5按照自定协议进行间歇性导通关断，来改变第一感应线圈L1所组成谐振回路的谐振参数：谐振控制开关Q5导通时，调节电容C3并联于第一感应线圈L1两端；从公式

可知,当电容C变大时，谐振频率F变小而偏离原来的工作频率，回路呈现容性阻抗，致其回路中充电电流变小，从而充电模组内的谐振回路的谐振电流同时减小。充电模组的谐振回路可以包括第二电阻R2，充电模组检测第二电阻R2两端电压随着协议变大或变小形成脉冲信号(如图3所示)，从而同步接收到气溶胶发生装置的满电信号，随之将流经第二感应线圈的谐振电流的频率降低到第二感应线圈L2与第二电容C2谐振频率的1/10，降低谐振电流的大小，达到降功耗的作用，即低功耗模式。所述第二电阻R2用于监测流经所述第二感应线圈L2的谐振电流大小，用来判断气溶胶发生装置是否插入充电座中，以及气溶胶发生装置是否充满电，所述第二电阻R2的两端电压分别接入充电模组的控制模块。

所述整流电路A1可以为半波整流电路、全波整流电路或者桥式整流电路。示例的，整流电路A1可以具体为桥式整流电路，包括第一二极管D1、第二二极管D2、第三二极管D3以及第四二极管D4，其中，所述第一二极管D1与所述第二二极管D2串联，所述第三二极管D3与所述第四二极管D4串联，所述变压器T1的的第一输出端连接所述第一二极管D1的正极，所述变压器T1的第二输出端连接所述第四二极管D4的正极，所述第二二极管D2的正极与所述第三二极管D3的正极同时接地，所述第一二极管D1的负极与所述第四二极管D4的负极同时连接所述第四场效应晶体管Q4的漏极。
需要说明的是，变压器T1的作用将交流电压为220V的市电电压转换为交流电压为5V的工作电压，经过第一二极管D1、第二二极管D2、第三二极管D3以及第四二极管D4的整流桥整流输出直流电流。第二电容C2、第二电阻R2、第三场效应晶体管Q3以及第四场效应晶体管Q4组成谐振电路A2，将直流电流转换成谐振输出的谐振电流，输出给第二感应线圈L2，电磁加热的气溶胶发生模组感应后进行充电。
其中，所述第三场效应晶体管Q3的栅极与所述第四场效应晶体管Q4的栅极分别连接所述充电模组的控制模块，所述充电模组的控制模块为充电模组输出充电电流控制信号，在本实施例中具体为互补PWM脉冲信号，所述第三场效应晶体管Q3与所述第四场效应晶体管Q4由充电座的控制模块输出互补PWM脉冲信号进行驱动，该PWM脉冲信号固定50％占空比，待机状态时所述WM脉冲信号的频率为第二感应线圈L2与第二电容C2谐振频率的1/10，旨在降低功耗；当气溶胶发生模组插入充电模组时，流经第二感应线圈L2、第二电阻R2电流变大，第二电阻R2两端的电压值变大，经过采集第二电阻R2两端的电压(MCU_AD1,MCU_AD2)并输出至充电模组的控制模块，即可识别到气溶胶发生模组插入充电，此时充电模组的控制模块将充电电流控制信号的频率逐步提高，使得流经第二感应线圈L2的谐振电流的频率得到提高，直到接近第二感应线圈L2与第二电容C2的谐振频率，谐振电流的大小也达到设定充电电流为止，且谐振电流的大小仍可以通过采集第二电阻R2两端电压进行判断。
在本实施例中，由充电模组对市电电压进行降压，气溶胶发生模组中的第一感应线圈L1结合充电模组中的第二感应线圈L2进行电磁感应充电，使得降压后的工作电压从充电模组中的第二感应线圈L2电磁感应传输至气溶胶发生模组中的第一感应线圈L1，使得气溶胶发生模组中的电流增大，气溶胶发生模组的控制模块控制谐振控制开关Q5关断，电流能够流经至电池进行充电，反之，电池充满电，气溶胶发生模组的控制模块获得电池充满电的信号，控制谐振控制开关Q5导通，而谐振控制开关Q5与第一感应线圈L1并联进而使得频率变小，回路呈现容性阻抗，致其回路中充电电流变小，从而充电模组内的谐振回路的谐振电流同时减小，实现控制谐振控制开关Q5的间歇性导通关断而改变第一感应线圈L1所处的谐振参数，实现电池充满电时对充电模组的反馈，从而降低第二感应线圈L2的谐振电流，达到降低功耗，节约电能。
