图 3为图 1中微控制器 20及与其连接的气流传感器 10、 音频模块 50及 指示单元 60的电路原理图， 参见图 1至图 3， 在本实施例中， 微控制器 20优 选由型号为 SN8P2712的芯片实现且该控制电路包括两个气流传感器， 其中一 个气流传感器通过接口 Mil与微控制器 20连接， 另一个气流传感器为备用气 流传感器， 其通过接口 MI2与微控制器 20连接， 当其中一个气流传感器失效 时， 该控制电路仍可控制电子烟正常工作。 具体地， 两个气流传感器的信号输 出端均分别通过对应的接口及二极管 Dl、 D2连接至微控制器 20的第 "4" 引 脚。
当用户吸食电子烟时，会形成高速气流，气流传感器便采集到用户吸入电 子烟内的气流信号，并将其转换成吸烟信号发送给微控制器 20的第" 4"引脚， 在微控制器 20的第" 4"引脚检测到吸烟信号时，便通过第" 17"引脚和第" 15" 引脚输出信号给音频模块 50中的音频芯片 501，在本实施例中，音频芯片 501 的型号优选为 AP8921A, 微控制器 20的第 "17"引脚连接至音频芯片 AP8921A 的第 "15"引脚， 当微控制器 20的第 "4"引脚检测到吸烟信号时， 微控制器 20的第 "17"引脚便输出信号以开启该音频芯片， 微控制器 20的第 "15"引 脚连接至音频芯片 AP8921A的第 " 10"引脚， 以选中所对应的音频信息， 即该 音频芯片预先存储的水声音音频信息， 通过第 "7" 引脚输出至声音放大单元 502, 并经声音放大单元 502中三极管 Q11的放大作用， 驱动扬声器 503 (图 中所示为 SPK1) 发出与水声音音频信息对应的模拟水烟水声， 因此可以模拟 真实水烟水声，无需像现有电子烟通过搭配储存水的水瓶或水盆以在用户吸烟 时发出水声。 具体地， 上述滤波单元 504包括电阻 R5、 电感 L1以及电容 C30 , 声音放 大单元 502包括电阻 R56、 电阻 R29以及开关管 Q11 , 其中： 电阻 R5和电感 L1并联连接后的一端与电池 30和音频芯片 501的复位端即第 " 16 "引脚连接， 电阻 R5和电感 L1并联连接后的另一端与扬声器 503的正输入端 SP+连接； 电 阻 R56的一端与音频芯片 501的音频信号输出端即第 " 7 "引脚连接， 电阻 R56 的另一端与电阻 R29的一端和开关管 Q11的基极连接，电阻 R29的另一端与开 关管 QU的发射极均接地， 开关管 QU的集电极与扬声器 503的负输入端 SP- 连接。
在本实施例中指示单元 60又具体包括三色 LED灯 LED2，该三色 LED灯 LED2 包括一个红色的发光二极管 RED、 一个蓝色的发光二极管 BLUE及一个绿色的 发光二极管 GREEN , 红色的发光二极管、 蓝色的发光二极管及绿色的发光二极 管的阳极均与电池 30的正极连接。 红色的发光二极管的阴极、 蓝色的发光二 极管的阴极及绿色的发光二极管的阴极分别对应经电阻 R43、 电阻 R42及电阻 R41之后， 分别与三个场效应管 Q14、 场效应管 Q13及场效应管 Q12的漏极连 接， 场效应管 Q14的源极接地、 场效应管 Q13及 Q12 的源极分别经电阻 R58 及电阻 R57接地。 这三个场效应管的栅极分别对应连接至微控制器 20的三个 输出端口即第 " 7 "引脚至第 " 9 "引脚。 微控制器 20还包括三个输入端口 101 至 103， 分别对应微控制器的第 " 6 " 引脚、 第 " 16 " 引脚和第 " 18 " 引脚， 如图所示， 输入端口 101连接电阻 R35和电阻 R36的连接点， 输入端口 102 连接电阻 R37和电阻 R38的连接点， 输入端口 103连接电阻 R39和电阻 R40 的连接点。当需要改变这三个输入端口的电平状态时，只需将电阻上下拉即口， 即这三个输入端口可以分别与电池 30的正极或地连接， 当与电池的正极连接 时， 该输入端口的电平状态为高电平状态， 当接地时， 则该输入端口的电平状 态为低电平状态。
上述微控制器 20还包括一存储单元（图未示），该存储单元存储有微控制 器 20上述三个输入端口 101至 103的电平状态及与这三个输入端口的电平状 态对应的用于表示电池 30在不同充电状态下的颜色。在微控制器 20的第 "4 " 引脚没有检测到吸烟信号时， 微控制器 20根据上述三个输入端口 101至 103 的电平状态， 査找与之对应的表示电池 30在不同充电状态下的第一颜色， 并 通过上述与三色 LED灯连接的三个输出端口， 即微控制器 20的第 " 7 "引脚至 第 "9 " 引脚输出相应信号以控制该三色 LED灯发出第一颜色的光。 特别地， 第一颜色包括用于表示电池 30在充电中状态下的颜色及用于表示电池 30在充 电满状态下的颜色， 其中： 用于表示电池 30在充电中状态下的颜色及用于表 示电池 30在充电满状态下的颜色为两种不同的颜色。
上述存储单元还存储有与微控制器 20的上述三个输入端口 101至 103的 电平状态对应的用于表示用户在吸烟的第二颜色， 即在微控制器 20的第 "4 " 引脚接收到吸烟信号时控制三色 LED灯需显示的颜色。 在微控制器 20检测到 吸烟信号时， 微控制器 20根据微控制器 20的上述三个输入端口 101至 103 的电平状态， 査找与之对应的表示用户在吸烟的第二颜色， 并通过微控制器 20的第 " 7 " 引脚至第 "9 " 弓 1脚输出相应信号以控制三色 LED灯发出第二颜 色的光。
上述微控制器 20预先将三个输入端口 101至 103的电平状态与对应的用 于表示电池 30在不同充电状态下的颜色及抽烟时的颜色对应存储， 如表 1所 表 1
Figure imgf000012_0001
例如， 当微控制器 20的三个输入端口 101至 103均接地时， 其电平状态 均为低电平状态， 所对应的值为 000， 通过微控制器 20的第 " 3 "引脚检测电 池 30此时的充电状态， 若微控制器 20的第 "3 " 引脚电平为低电平时， 表示 电池处于充电中状态， 此时微控制器 20通过第 " 7 " 引脚至第 " 9 " 引脚控制 三色 LED灯显示的颜色为红色。若微控制器 20的第" 3 "引脚电平为高电平时， 表示电池处于充电满状态， 此时微控制器 20通过第 " 7 " 引脚至第 " 9 " 弓 1脚 控制三色 LED灯所显示的颜色为绿色。 此外， 当微控制器 20的第" 4 "引脚接 收到吸烟信号时， 微控制器 20控制三色 LED灯所显示的颜色也为红色， 且只 要在用户吸烟时， 微控制器 20便控制三色 LED灯便显示抽烟颜色， 只有在没 有接收到吸烟信号时， 再显示代表充电状态的颜色。
再例如， 当微控制器 20的输入端口 101和 102均接地、 输入端口 103与 电池正极连接时， 则输入端口 101和 102的电平状态均为低电平状态，输入端 口 103的电平状态为高电平状态， 所对应的值为 001， 电池 30在充电中状态 及充电满状态时微控制器 20控制三色 LED灯所显示的颜色也分别为红色和绿 色。 不同的是， 当微控制器 20 的第 "4 " 引脚接收到吸烟信号时， 微控制器 20控制三色 LED灯所显示的颜色为橙色。 其余情况与此类似， 在此不再赘述。 因此，可以方便地改变微控制器输入端口 101至 103的电平状态（电阻上下拉）， 从而改变电池不同充电状态时三色 LED灯显示的颜色及抽烟时三色 LED灯显示 的颜色。
在上述控制电路中， 微控制器 20的第" 4 "引脚接收到吸烟信号时， 通过 微控制 20控制音频芯片 501输出模拟水声音音频信息， 之后通过放大作用后 驱动扬声器 503输出模拟水烟水声， 并同时通过微控制器 20的第 " 7 "引脚至 第 " 9 " 引脚输出信号以控制指示单元 60中的三色 LED灯发出吸烟颜色的光， 该吸烟颜色预先存储在微控制器 20的存储单元中。 此外， 也可以通过调节扬 声器发出模拟水烟水声的音量，音频芯片将音量分成不同的等级， 并将检测到 的代表音量的信号反馈至微控制器，微控制器再根据这一信号来判断当前扬声 器发出的模拟水烟水声的音量处于哪个等级， 之后控制指示单元中的三色 LED 烟发出相应颜色的光，即微控制器中的存储单元预先存储有音量等级及其对应 的吸烟颜色。
上述控制电路中的第二开关单元包括场效应管 Q4A和 Q4B及电阻 R60 ,其 中： 场效应管 Q4A和 Q4B的栅极均与微控制器 20的第 " 10 " 引脚连接， 在微 控制器 20的第 "4 "引脚接收到吸烟信号时， 其控制第 " 10 "引脚输入高电平 信号， 以控制场效应管 Q4A和 Q4B导通， 而电子烟雾化器中的电热丝连接电池 正极及场效应管 Q4B的源极即端口 OUT之间， 当场效应管 Q4A和 Q4B导通时， 相当于电热丝接在电池正极与地之间， 即电池与电热丝的供电通路导通， 电热 丝发热以雾化烟油， 实现电子烟正常工作。
图 4 为电池保护模块的电路原理图， 其包括电池保护芯片及第一开关单 元， 如图所示， 电池保护芯片的型号为 S8241 , 第一开关单元主要包括场效应 管 Q2A和 Q3A及场效应管 Q2B和 Q3B。 当检测到电池 30处于过充状态时， 通 过电池保护芯片 S8241的第 " 5 "引脚输出信号控制场效应管 Q2A和 Q3A断开， 此时外接电源不再对电池 30进行充电。当检测到电池 30处于过放状态时，通 过电池保护芯片 S8241的第 "4 "引脚输出信号控制场效应管 Q2B和 Q3B断开， 此时电池 30不再提供内部电源。
本发明还提供了一种电子烟， 该电子水烟包括上述实施例中的控制电路。 该电子水烟包括用于雾化烟油的雾化器， 雾化器包括用于雾化烟油的电热丝， 在控制电路中的微控制器 20检测到吸烟信号时，微控制器 20控制该雾化器中 的电热丝工作， 以实现对电子烟的烟油进行雾化。
本发明还提供一种电子烟的控制方法， 该控制方法包括：
外接电源经直流适配 70转换为直流电源后通过充电管理模块 40对电池 30进行充电管理并将电池 30的充电状态发送给微控制器 20。具体地， 充电管 理模块 40由型号为 BQ24090的充电管理芯片实现，当电池 30处于充电中状态， 该芯片 BQ24090的第 " 8 "引脚输出低电平， 当电池 30处于充电满状态时， 该 芯片 BQ24090的第 " 8 " 引脚输出高电平， 并由微控制器 20的第 " 3 " 引脚接 气流传感器 10采集每次吸入电子烟内的气流信号并将气流信号转换成吸 烟信号发送给微控制器 20。 在该歩骤中， 当用户吸食电子烟时， 可形成高速 气流，气流传感器 10感知到气流后生成吸烟信号并发送给微控制器 20的第" 4 " 引脚；
微控制器 20根据接收到的吸烟信号控制音频模块 50发出模拟电子水烟水 声。 具体地， 在微控制器 20的第 "4" 引脚接收到吸烟信号后， 微控制器 20 通过其第" 17"引脚和第" 15"引脚分别输出信号给音频芯片 AP8921A的第" 15" 引脚和第 "10" 引脚， 开启该音频芯片， 并输出预先录制的水声音音频信息， 通过三极管 Q11的放大作用后， 驱动扬声器 SPK1发出模拟水烟水声。 同时， 在微控制器 20的第 "4" 引脚接收到吸烟信号后， 微控制器 20的第 "10" 引 脚输出高电平信号， 场效应管 Q4A和 Q4B导通， 电池 30与电子烟雾化器中的 电热丝的供电通路导通， 电热丝工作， 实现对电子烟的烟油进行雾化。
在上述控制方法中，微控制器 20中的存储单元有预先将三个输入端口 101 至 103的电平状态与对应的用于表示电池 30在不同充电状态下的颜色及抽烟 时的颜色对应存储， 当微控制器 20的第 "4"引脚没有检测到吸烟信号时， 上 述控制方法还包括：
根据微控制器 20的三个输入端口的电平状态， 査找与之对应的代表不同 充电状态下的第一颜色， 并通过微控制器 20的三个输出端口控制三色 LED灯 发出所述第一颜色的光。 其中， 在本实施例中， 微控制器 20的三个输入端口 101至 103分别对应微控制器 20的第 "6"引脚、 第 "16"引脚和第 "18"引 脚， 输出端口为微控制器 20 的第 "7" 引脚至第 "9" 引脚。 当微控制器 20 的第 "4" 引脚没有接收到吸烟信号， 此时根据微控制器 20的第 "3" 引脚的 电平状态判断此时电池的充电状态， 再根据微控制器 20的三个输入端口 101 至 103的电平状态在输出端口即第 "7"引脚至第 "9"引脚输出相应信号以控 制三色 LED灯 （图 3中所示为 LED2) 显示电池在不同充电状态下的颜色。 第 一颜色包括两种不同的颜色，分别为电池在充电中状态的颜色及在充电满状态 下的颜色。
在微控制器 20的第 "4" 引脚检测到吸烟信号时， 上述控制方法还包括： 根据微控制器 20的三个输入端口 101至 103的电平状态， 査找与之对应 的表示用户在吸烟的第二颜色， 并通过三个输出端口 （微控制器 20的第 " 7" 引脚至第 "9" 引脚） 控制三色 LED灯发出所述第二颜色的光。 即当用户在吸 烟时， 微控制器 20优先控制三色 LED灯显示抽烟颜色。
因此， 实施本发明的一种控制电路、 电子烟及电子烟的控制方法， 通过微 控制器在接收到吸烟信号时，控制音频模块发出水烟水声， 实现了用户在吸食 电子烟时， 可以电子模拟发出水声， 无需像现有电子烟需搭配一个储存水的水 瓶或水盆以在吸食电子烟时发出水声，通过电子模拟真实水烟水声的功能， 有 利于使用电子烟及有利于戒烟，且通过结构简单巧妙的所述滤波单元进行滤波 及所述声音放大单元对音频信号进行放大后，所述水声音质较好，音量较大且 逼真地模仿电子水烟的声音，极大地提高了用户体验，较好地避免了声音细小， 不稳定， 杂音较多， 音质差等问题。 同时通过微控制器控制三色 LED灯在不同 充电状态下显示不同的颜色， 实现了在用户吸食电子烟时， 显示正在吸烟的颜 色，当没有在吸烟时便显示电池正在充电中或充电满的颜色，提高了用户体验。
上面结合附图对本发明的实施例进行了描述，但是本发明并不局限于上述 的具体实施方式， 上述的具体实施方式仅仅是示意性的， 而不是限制性的， 本 领域的普通技术人员在本发明的启示下，在不脱离本发明宗旨和权利要求所保 护的范围情况下， 还可做出很多形式， 这些均属于本发明的保护之内。
