Description
本申请涉及一种电子雾化装置、电子雾化装置的控制方法及计算机设备。
电子烟是一种模仿香烟的电子产品，又名虚拟香烟、电子雾化装置。电子烟作为香烟的替代品，具有与香烟相似的外形、烟雾和味道，但电子烟中一般不含香烟中的焦油、悬浮微粒等有害成分。
现有的电子雾化装置一般采用直流PWM降压方案来控制输出功率；然而，发明人意识到，通过调节输出PWM的占空比来实现PWM降压斩波控制，输出功率得不到有效的保证。PWM降压输出方式，随着电芯电量的降低，输出功率会有比较明显的波动，造成前后的抽吸口感差异大，且最大电压受限于电芯电压。若需要采用升压控制，一般需要设置全桥电路进行升压控制，还需要增设驱动电路，使得控制电路复杂、占用电子雾化装置内部空间大，且成本较高，对于电子雾化装置的使用场景而言难以实现升压输出控制的需求。

正如背景技术所述，现有技术中的电子雾化装置有输出功率难以保证的问题，经发明人研究发现，出现这种问题的原因在于，由于电子雾化装置一般采用直流PWM降压方法控制输出功率，而采用降压控制时最大电压受限于电芯电压，使得在电芯电量降低时，输出功率会产生波动。而升压控制电路一般需要设置专门的驱动电路，使得升压控制电路的元件更加多，体积更大，若在电子雾化装置内设置常见的升压控制电路，会使电子雾化装置本身的体积也要进行增大，同时复杂的电路导致成本也会上升。如图1所示为传统的升压方案，需要设置驱动电路驱动功率MOS管，同时还需要设置至少四个功率MOS管，使得升压电路构成复杂，体积较大。
在其中一个实施例中，如图2所示，提供了一种电子雾化装置，包括：
雾化组件210，用于对气溶胶形成基质进行雾化；
半桥升压电路220，用于电连接电源100及雾化组件210，将电源电压进行升压后向雾化组件210提供工作电压，工作电压用于为雾化组件210供电进行雾化；
控制单元230，用于根据电源电压及预设的目标电压输出高频PWM控制信号至半桥升压电路220，高频PWM控制信号用于控制半桥升压电路220进行升压，以使工作电压达到目标电压。
雾化组件210用于加热气溶胶形成基质实现雾化，产生气溶胶供用户抽吸。为了保证用户的使用感，一般在抽吸阶段会采用恒压控制，使雾化组件210的电压恒定，产生均匀的气溶胶。半桥升压电路220设置于电源100及雾化组件210之间，用于将电源电压进行升压，使工作电压达到预设的目标电压，使雾化组件210进行雾化。
控制单元230包括具备输出高频信号能力的控制器232，如单片机或其他微处理器。能够直接为半桥升压电路220提供高频PWM控制信号，实现升压控制，无需增设驱动器或驱动电路。采用单片机输出高频PWM控制信号直接驱动半桥升压电路，无需驱动IC。电源电压是指电子雾化装置的供电 电源的电压，若电子雾化装置的供电电源为外接电源100，则为该外接电源的电压；若电子雾化装置的供电电源为电芯，则为电芯电压。
高频PWM控制信号的占空比根据下述表达式确定：
D＝Ton/T＝Vo/Vbat
D为高频PWM控制信号的占空比，Vo为目标电压，Vbat为电源电压，Ton为高频PWM控制信号的有效电平时间，T为高频PWM控制信号的周期。
上述电子雾化装置中，通过高频PWM控制信号驱动半桥升压电路220，无需额外设置驱动电路，控制单元230直接驱动半桥升压电路220将电源电压升压后提供工作电压为雾化组件210供电，根据电源电压及预设的目标电压确定高频PWM控制信号，能够简单且精准地实现升压控制，且电路占用空间小。
在其中一个实施例中，如图3所示，控制单元230包括：
工作电压检测电路231，用于检测工作电压；
控制器232，用于获取工作电压检测电路231反馈的工作电压，并根据目标电压与工作电压的差值调节高频PWM控制信号，以使工作电压恒定。
在电子雾化装置工作过程中，由于元件内阻变化或电源电压变化等原因，可能会使得工作电压发生变化，通过工作电压检测电路231对半桥升压电路220提供的工作电压进行实时检测，并反馈至控制器232，控制器232根据目标电压与工作电压的差值对高频PWM控制信号进行调节，以使工作电压维持在目标电压。
在其中一个实施例中，电源100为电芯，如图4所示，控制单元230还包括：
电芯电压检测电路233，用于电连接电芯，并检测电芯电压；
控制器232还用于获取电芯电压检测电路233反馈的电芯电压，并根据电芯电压及目标电压调节高频PWM控制信号，以使工作电压恒定。
电芯随着电量减少，电芯电压会降低，此时若保持原来的高频PWM控 制信号，则工作电压会降低，使得无法维持恒压输出。利用电芯电压检测电路233对电芯电压进行实时检测，并反馈至控制器232，控制器232根据当下的电芯电压及预设的目标电压计算第二占空比。将高频PWM控制信号的占空比调节至第二占空比，将工作电压维持在目标电压。若电芯电压降低，则需要增大高频PWM控制信号的占空比；若电芯电压通过充电等方式增大，则需要降低高频PWM控制信号的占空比。
当输出负载电阻变小，依据欧姆定律I＝V/R，输出电流相应的会增大。由于电芯，导线，控制电路的MOS管内阻的影响，实际电芯电压和施加到负载两端的电压都会降低。在其中一个实施例中，工作电压检测电路231配合电芯电压检测电路233，同时反馈工作电压及电芯电压至控制器232，控制器232根据工作电压、电芯电压及预设的目标电压对高频PWM控制信号的占空比进行实时调节，实现恒压或恒功率输出，保证烟雾量和雾化温度不受电芯电量或雾化组件210阻值变化的影响。
在其中一个实施例中，如图5所示，半桥升压电路220包括：电容C1、电容C2、电感L、二极管D、MOS管Q1及电阻R；
电容C1的第一端用于电连接电源100Vbat，第二端接地；
电感L的第一端电连接电容C1的第一端，第二端电连接MOS管Q1的漏极；
MOS管Q1的栅极电连接控制单元230的高频PWM控制信号输出端PWM-OUT，源极接地；
二极管D的阳极电连接MOS管Q1的漏极，阴极电连接雾化组件210的第一电源100端Vo+；
电容C2的第一端电连接二极管D的阴极，第二端电连接雾化组件210的第二电源100端Vo-；
电阻R的第一端电连接MOS管Q1的栅极，第二端接地。
当MOS管Q1导通，电源电压加到电感L上，电能以磁场能的形式存储在电感L中，此时由电容C2为雾化组件210供电，二极管能够防止电容C2 输出的电压倒灌至电源100。当MOS管Q1断开，电源100和电感同时通过二极管为雾化组件210供电，同时为电容C2充电。通过高频PWM控制信号控制MOS管Q1的通断，实现升压，改变高频PWM控制信号的占空比即可改变工作电压，根据电芯电压和/或工作电压的变化对高频PWM控制信号的占空比进行调节，实现恒压或恒功率输出。无需驱动电路并且相比传统升压方案减少一半功率MOS管，通过单片机输出高频PWM控制信号直接驱动半桥升压电路升压。由于高频PWM控制信号直接驱动半桥升压电路可省略驱动电路及一半功率MOS管，使得该升压电路简单，成本更低，体积更小。

确定高频PWM控制信号的第一占空比后，输出具有第一占空比的高频PWM控制信号至半桥升压电路220，控制半桥升压电路220对电源电压进行升压处理后得到工作电压为雾化组件210供电。

步骤S500，根据目标电压与工作电压的差值调节高频PWM控制信号的占空比。
在电子雾化装置工作过程中，由于元件内阻变化或电源电压变化等原因，可能会使得工作电压发生变化，通过工作电压检测电路231对半桥升压电路220提供的工作电压进行实时检测，并反馈至控制器232，控制器232根据目标电压与工作电压的差值对高频PWM控制信号进行调节，以使工作电压维持在目标电压。
根据下述表达式确定调节后的占空比：
D′为调节后的占空比，V′
0为工作电压。

步骤S700，根据电芯电压及目标电压计算第二占空比；
步骤S800，根据第二占空比调节高频PWM控制信号。
电芯随着电量减少，电芯电压会降低，此时若保持原来的高频PWM控制信号，则工作电压会降低，使得无法维持恒压输出。利用电芯电压检测电 路233对电芯电压进行实时检测，并反馈至控制器232，控制器232根据当下的电芯电压及预设的目标电压计算第二占空比。将高频PWM控制信号的占空比调节至第二占空比，将工作电压维持在目标电压。若电芯电压降低，则需要增大高频PWM控制信号的占空比；若电芯电压通过充电等方式增大，则需要降低高频PWM控制信号的占空比。
