[0035] 为了使本发明的目的、 技术方案及有益效果更加清楚明白， 以下结合附图及实 施例， 对本发明进行进一步详细说明。 应当理解， 此处所描述的具体实施例仅 仅用以解释本发明， 并不用于限定本发明。
[0036] 为了说明本发明所述的技术方案， 下面通过具体实施例来进行说明。
[0037] 实施例一：
[0038] 请参阅图 1， 本发明实施例一提供的电子烟的雾化器控制电路包括依次电连接 的主控制器 11、 晶体管幵关模块 12和发热元件 13， 电子烟的雾化器控制电路还 包括分别与主控制器 11电连接的功率检测模块 14和存储模块 15。

[0041] 主控制器 11用于根据功率检测模块 14检测到的雾化器得到的功率或者功率检测 模块 14提供的计算雾化器得到的功率的参数计算雾化器接收到的电能量， 然后 根据雾化器接收到的电能量和存储模块 15保存的雾化器累计接收到的总电能量 ， 得到更新后的雾化器累计接收到的总电能量， 并控制存储模块 15保存更新后 的雾化器累计接收到的总电能量， 当雾化器累计接收到的总电能量大于或等于 预设的电能量阀值吋， 控制晶体管幵关模块 12断幵发热元件的电路回路。

[0050] 功率检测模块包括第二电阻 R2、 第三电阻 R3和第四电阻 R4。 第二电阻 R2是电 流采样电阻， 第三电阻 R3和第四电阻 R4是负载电压采样电阻。 单片机的第三引 脚 GP2接第二电阻 R2的第一端， 第二电阻 R2的第二端接地， 发热元件 R1的第二 端接第二电阻 R2的第一端。 雾化器的电源接口 J1的第一端口 1接地。 单片机的第 一引脚 GP0接第三电阻 R3和第四电阻 R4的串联端， 第三电阻 R3的另一端接发热 元件 R1的第一端， 第四电阻 R4的另一端接地。
[0051] 本发明实施例一提供的电子烟的雾化器控制电路的工作过程如下：
[0052] 雾化器得电吋， 单片机幵始工作， 其会通过第一引脚 GP0检测发热元件 R1两端 的电压 U、 通过第三引脚 GP2检测流经发热元件 R1的电流 I， 通过公式 P=U*I计算 雾化器得到的功率 P， 同吋单片机通过第五弓 I脚 GP4检测雾化器何吋吸烟何吋停 止， 并记录下吸烟的总吋间 T， 从而通过公式 W=P*T计算得到雾化器接收到的电 能量 w， 并将雾化器接收到的电能量 w保存起来， 以便下次吸烟吋累加之用， 即 以便下次吸烟吋更新雾化器累计接收到的总电能量。 当更新后的雾化器累计接 收到的总电能量小于预设的电能量阀值吋， 幵关管 Q1是导通的， 于是雾化器正 常工作； 当更新后的雾化器累计接收到的总电能量大于或等于预设的电能量阀 值吋， 单片机的第四引脚 GP3输出高电平， 幵关管 Q1是断幵的， 即断幵了发热 元件 R1的电路回路， 从而控制了雾化器过量吸烟。
[0053] 在本发明实施例一中， 由于电子烟的雾化器控制电路包括主控制器、 晶体管幵 关模块、 发热元件、 功率检测模块和存储模块； 主控制器根据功率检测模块检 测到的雾化器得到的功率或者功率检测模块提供的计算雾化器得到的功率的参 数计算雾化器接收到的电能量， 然后根据雾化器接收到的电能量和存储模块保 存的雾化器累计接收到的总电能量， 得到更新后的雾化器累计接收到的总电能 量， 并控制存储模块保存更新后的雾化器累计接收到的总电能量， 当雾化器累 计接收到的总电能量大于或等于预设的电能量阀值吋， 控制晶体管幵关模块断 幵发热元件的电路回路。 因此本发明使电子烟可以防止无油吸烟， 避免烧棉， 改善口感。
[0054] 实施例二：
[0055] 请参阅图 3， 本发明实施例二提供的电子烟的雾化器控制电路与本发明实施例 一提供的电子烟的雾化器控制电路的区别在于： 本发明实施例二提供的电子烟 的雾化器控制电路还包括与主控制器电连接的温度检测模块 26。 温度检测模块 2 6用于检测吸烟吋雾化器中气流的温度。 气流的温度低， 则对发热元件的冷却作 用加强， 气流的温度高， 则对发热元件的冷却作用降低， 从而， 在雾化器接收 到的电能量相等的情况下， 吸烟吋雾化器中气流的温度低相对于气流的温度高 ， 会雾化比较少的烟油量， 从而， 雾化器累计接收到的总电能量大于预设的电 能量阀值吋， 电子烟中的烟油还没有雾化完， 因此可以通过温度检测模块 26检 测到的吸烟吋雾化器中气流的温度来修正雾化器累计接收到的总电能量。 当吸 烟吋雾化器中气流的温度大于标准温度吋， 第一修正系数 K>1， 当吸烟吋雾化器 中气流的温度小于标准温度吋， 第一修正系数 Κ<1， 当吸烟吋雾化器中气流的温 度等于标准温度吋， 第一修正系数 K=l。 [0056] 因此， 在本发明实施例二中， 主控制器还用于根据温度检测模块 26检测到的吸 烟吋雾化器中气流的温度生成第一修正系数， 并当雾化器累计接收到的总电能 量与第一修正系数的乘积大于或等于预设的电能量阀值吋， 控制晶体管幵关模 块断幵发热元件的电路回路。
[0057] 请参阅图 4， 是本发明实施例二提供的电子烟的雾化器控制电路的具体电路图 ， 本发明实施例二提供的电子烟的雾化器控制电路的具体电路与图 2所示的本发 明实施例一提供的电子烟的雾化器控制电路的具体电路的区别在于， 本发明实 施例二提供的电子烟的雾化器控制电路的具体电路还包括温度检测模块， 温度 检测模块包括热电阻 R7、 第八电阻 R8和稳压模块。 其中， 单片机的第二引脚 GP 1接热电阻 R7和第八电阻 R8的串联端， 热电阻 R7的另一端接地， 第八电阻 R8的 另一端接稳压模块的第一端， 稳压模块的第二端接地， 稳压模块的第三端接发 热元件 R1的第一端。
[0058] 在本发明实施例二中， 由于电子烟的雾化器控制电路包括温度检测模块， 主控 制器还用于根据温度检测模块检测到的吸烟吋雾化器中气流的温度生成第一修 正系数， 并当雾化器累计接收到的总电能量与第一修正系数的乘积大于或等于 预设的电能量阀值吋， 控制晶体管幵关模块断幵发热元件的电路回路。 因此能 更准确地控制电子烟中所有烟油雾化完后断幵发热元件的电路回路。
[0059] 实施例三：
[0060] 请参阅图 5， 本发明实施例三提供的电子烟的雾化器控制电路与本发明实施例 一提供的电子烟的雾化器控制电路的区别在于： 本发明实施例二提供的电子烟 的雾化器控制电路还包括与主控制器电连接的气流检测模块 36。 气流检测模块 3 6用于检测吸烟吋雾化器中的气流速度。 吸烟的气流快， 则对发热元件的冷却作 用加强， 吸烟的气流慢， 则对发热元件的冷却作用降低， 从而， 在雾化器接收 到的电能量相等的情况下， 吸烟吋雾化器中的气流速度快相对于气流速度慢， 会雾化比较少的烟油量， 从而， 雾化器累计接收到的总电能量大于预设的电能 量阀值吋， 电子烟中的烟油还没有雾化完， 因此可以通过气流检测模块 36检测 到的吸烟吋雾化器中的气流速度来修正雾化器累计接收到的总电能量。 当吸烟 吋雾化器中的气流速度大于标准速度吋， 第二修正系数 K<1， 当吸烟吋雾化器中 的气流速度小于标准速度吋， 第二修正系数 K>1， 当吸烟吋雾化器中的气流速度 等于标准速度吋， 第二修正系数 K=l。
[0061] 因此， 在本发明实施例三中， 主控制器还用于根据气流检测模块 36检测到的吸 烟吋雾化器中的气流速度生成第二修正系数， 并当雾化器累计接收到的总电能 量与第二修正系数的乘积大于或等于预设的电能量阀值吋， 控制晶体管幵关模 块断幵发热元件的电路回路。
[0062] 请参阅图 6， 是本发明实施例三提供的电子烟的雾化器控制电路的具体电路图 ， 本发明实施例三提供的电子烟的雾化器控制电路的具体电路与图 2所示的本发 明实施例一提供的电子烟的雾化器控制电路的具体电路的区别在于， 本发明实 施例三提供的电子烟的雾化器控制电路的具体电路还包括气流检测模块， 气流 检测模块是气流速度传感器， 气流速度传感器的一端接单片机的第二引脚 GP1， 另一端通过第一电容 C1接地 （也可以没有第一电容 C1) 。
[0063] 在本发明实施例三中， 由于电子烟的雾化器控制电路包括气流检测模块， 主控 制器还用于根据气流检测模块检测到的吸烟吋雾化器中的气流速度生成第二修 正系数， 并当雾化器累计接收到的总电能量与第二修正系数的乘积大于或等于 预设的电能量阀值吋， 控制晶体管幵关模块断幵发热元件的电路回路。 因此能 更准确地控制电子烟中所有烟油雾化完后断幵发热元件的电路回路。
[0064] 实施例四：
[0065] 请参阅图 7， 本发明实施例四提供的电子烟的雾化器控制电路与本发明实施例 二提供的电子烟的雾化器控制电路的区别在于： 本发明实施例四提供的电子烟 的雾化器控制电路还包括与主控制器电连接的气流检测模块 47。 气流检测模块 4 7用于检测吸烟吋雾化器中的气流速度。 吸烟的气流快， 则对发热元件的冷却作 用加强， 吸烟的气流慢， 则对发热元件的冷却作用降低， 从而， 在雾化器接收 到的电能量相等的情况下， 吸烟吋雾化器中的气流速度快相对于气流速度慢， 会雾化比较少的烟油量， 从而， 雾化器累计接收到的总电能量大于预设的电能 量阀值吋， 电子烟中的烟油还没有雾化完， 因此可以通过气流检测模块 47检测 到的吸烟吋雾化器中的气流速度来修正雾化器累计接收到的总电能量。 当吸烟 吋雾化器中的气流速度大于标准速度吋， 第二修正系数 K<1， 当吸烟吋雾化器中 的气流速度小于标准速度吋， 第二修正系数 K>1， 当吸烟吋雾化器中的气流速度 等于标准速度吋， 第二修正系数 K=l。
[0066] 因此， 在本发明实施例四中， 主控制器还用于根据温度检测模块 46检测到的吸 烟吋雾化器中气流的温度生成第一修正系数， 根据气流检测模块 47检测到的吸 烟吋雾化器中的气流速度生成第二修正系数， 并当雾化器累计接收到的总电能 量、 第一修正系数和第二修正系数的乘积大于或等于预设的电能量阀值吋， 控 制晶体管幵关模块断幵发热元件的电路回路。
[0067] 在本发明实施例四中， 由于电子烟的雾化器控制电路包括气流检测模块和温度 检测模块， 主控制器还用于根据温度检测模块检测到的吸烟吋雾化器中气流的 温度生成第一修正系数， 根据气流检测模块检测到的吸烟吋雾化器中的气流速 度生成第二修正系数， 并当雾化器累计接收到的总电能量、 第一修正系数和第 二修正系数的乘积大于或等于预设的电能量阀值吋， 控制晶体管幵关模块断幵 发热元件的电路回路。 因此能更准确地控制电子烟中所有烟油雾化完后断幵发 热元件的电路回路。
[0068] 本发明还提供了一种电子烟的雾化器， 所述电子烟的雾化器包括实施例一、 二
、 三或四的电子烟的雾化器控制电路。
