目前大部分的电子烟可分为电池杆和雾化器两大部分,其中雾化器部分存储有烟液,电池杆部分包含供电电池可提供加热电源。
一般的,由于电池杆中的电池为可充电的,因此,电池杆部分可以重复充电使用。而雾化器中的烟液用完后,需重新添加烟液或直接更换新的雾化器。若重新更换新的雾化器,则雾化器需与重复使用的电池杆相匹配。
由于对于不同的电子烟,其雾化器和电池杆的设计不同(例如尺寸、电池的供电电压等),在使用过程中,若消费者将不相匹配的雾化器与电池杆搭配使用,则可能会导致使用电子烟时出现故障或口感异常等问题。
而现有技术中的电池杆和雾化器不能实现在出现故障或口感异常问题前就知晓其是否匹配。

具体实施方式
为了对本实用新型的技术特征、目的和效果有更加清楚的理解,现对照附图详细说明本实用新型的具体实施方式。
参见图 1 为本实用新型实施例的电子烟的结构图。在本实用新型的实施例中,电子烟包括电池杆 20 和与电池杆 20 可拆卸连接的雾化器 30 。电池杆 20 内置第二无线识别模块 201 ,雾化器 30 内置第一无线识别模块 301 。雾化器 30 还包括:用于发热以雾化烟液的电热丝 302 。电池杆还包括:触发电路 204 、供电电池 202 、供电电路(图中未标识出)、微处理器 200 。其中,第二无线识别模块 201 分别与微处理器 200 和供电电池 202 连接,微处理器 200 与供电电池 202 连接,供电电路分别与供电电池 202 和微处理器 200 连接。触发电路 204 分别与供电电池 202 和微处理器 200 连接。

在本实用新型的实施例中,第二无线识别模块 301 通过其内置的第一天线 3011 发射一定频率的射频信号,当雾化器 30 进入第一天线 3011 的工作区时,第二无线 3012 接收第一天线 3011 发射的射频信号并产生感应电流;第一无线识别模块 301 获得能量被激活而将包含的识别信息的信号经编码器 3013 的编码后,调制电路 3012 将编码后的信号调制到载波振荡电路 3014 产生的载波上,调制后的信号经第一天线 3011 发送出去;第二天线接 2011 接收到从第一无线识别模块 301 发送来的电磁信号(其包含有识别信息),并将电磁信号转换为电信号后,由信号放大电路 2012 、解调电路 2013 和解码器 2014 依次对电信号进行放大、解调和解码,解码后得到的信号被传送到微处理器 200 ;微处理器 200 根据接收的信号判断该雾化器 30 的合法性(即该雾化器 30 是否和电池杆 20 匹配),若合法 (即匹配) ,则微处理器 200 导通对雾化器 30 的电热丝 302 的供电电路;若不合法(即不匹配),则微处理器 200 不导通供电电路。
参见图 3 为本实用新型的 信号放大电路和解调电路的电路图。其中,信号放大电路 2012 包括电容 C1 、电容 C2 、电容 C3 、电阻 R1 、电阻 R2 、三极管 PQ1 和电感 L1 ;解调电路 2013 包括电阻 R3 、可变电阻 R6 、比较器 PU1 、电阻 R4 和电阻 R5 。
具体的,电容 C1 的正极连接第二天线 2011 的一端,第二天线 2011 的另一端接地;电容 C1 的负极连接电阻 R1 的一端和电容 C2 的负极;电容 C2 的正极连接第二天线 2011 的一端、负极连接电容 C3 的正极和三极管 PQ1 的基极;三极管 PQ1 的发射极接地、集电极连接电感 L1 的一端及电阻 R3 的一端;电感 L1 的另一端连接电阻 R2 的一端;电阻 R2 的 另 一端连接电阻 R1 以及供电电池 202 的正极;电阻 R3 的另一端连接比较器 PU1 的同相输入端;比较器 PU1 的反相输入端连接可变电阻 R6 的一端 (可调端) ,可变电阻 R6 的另外两端分别连接供电电池 202 的正极和地;比较器 PU1 的正电源端连接供电电池 202 的正极、负电源端连接地、输出端( Vout )连接解码器 2014 ;电阻 R4 的一端连接供电电池 202 的正极,另一端连接比较器 PU1 的输出端;电阻 R5 的一端连接比较器 PU1 的输出端、另一端接地。

本实用新型实施例的电子烟的电池杆 20 对与其连接的雾化器 30 具有识别功能,且可对第一无线识别模块 301 包含的识别信息经加密处理,可防止数据复制,以避免由于识别信息被更改而导致本不匹配的雾化器 30 与电池杆 20 被误识别为匹配而进行连接。
在本实用新型的实施例中,识别信息可为 ID 信息,即不同的雾化器的 ID 信息不同。微处理器 200 判断雾化器是否合法,即根据 ID 信息进行判断。具体的,微处理器 200 可预先存储合法的雾化器的 ID 信息,当接收到经解码器 2014 解码后的包含 ID 信息的数据时,即将接收到的 ID 信息与预存的 ID 信息进行比较。若接收到的 ID 信息为预存的 ID 信息中的一个,则可判断为该雾化器合法。此外,识别信息也可为其他的标识信息,例如,序列号等,微处理器 200 只需预存与识别信息相对应的合法识别信息,即可实现准确判断雾化器是否合法。
优选的,本实用新型实施例的第二无线识别模块 201 包括 RFID 读写器芯片,其型号可为 RF69 、 RF68 、 U2270B 等;第一无线识别模块 301 包括 RFID 标签芯片,其型号可为 Monza 4 、 FM11RF32SH 等。

短路检测电路 205 用于检测供电电路是否发生短路,若检测到发生短路,则微处理器 200 控制开关电路 203 截止。
电压检测电路 206 用于检测输出电压。在本实用新型的实施例中,由于输出电压是由供电电池 202 提供的,因此,当检测到输出电压低时,表明供电电池 202 的电压低。由此,微处理器 200 可根据检测到的输出电压判断该检测到的电压是否低于设定值,若低于则进行复位操作。进行复位操作,可避免出现当外部电源对电压低于一定值的供电电池 202 进行充电时,出现不能正常进行充电的问题。
参见图 4 为 本实用新型实施例的电子烟电池杆的电路图。在本实用新型的实施例中,开关电路 203 和短路检测电路 205 均由 MOS 管 Q1 实现;状态指示电路 207 包括电阻 R7 和发光二极管 D1 ;电压检测电路 206 包括电阻 R8 。 本实用新型实施例的微处理器 200 的型号为 SN8P2711 。触发电路 204 包括 气流传感器或触发开关,其均包括输出端、接地端和电源端。在本实用新型的实施例中,触发电路 204 由气流传感器或按键开关,因此,触发电路 204 产生的触发信号包括气流触发信号或按键触发信号。当产生这两种触发信号时,均表明消费者的吸烟动作开始,此时,微处理器 200 需控制供电电路导通以实现给雾化器供电以雾化烟液产生吸烟效果。
具体的,微处理器 200 的第一引脚( VDD 引脚)通过滤波电容 C4 接地,微处理器 200 的第一引脚还接稳压二极管 D2 的阴极;稳压二极管 D2 的阳极接 VDD 连接供电电池 202 的正极;微处理器 200 的第二引脚( P0.2/Xout 引脚)连接触发电路 204 的输出端;微处理器 200 的第三引脚( P0.4/RST/Vpp 引脚)连接电阻 R8 的一端以及 MOS 管 Q1 的漏极;电阻 R8 的另一端连接供电电池 202 的正极;微处理器 200 的第四引脚( P5.3/BZ1/PWM1 引脚)连接 MOS 管 Q1 的栅极;微处理器 200 的第五引脚( P5.4/BZ0/PWM0 引脚)连接发光二极管 D1 的阴极;发光二极管 D1 的阳极连接电阻 R7 的一端,电阻 R7 的另一端连接供电电池 202 的正极;微处理器 200 的第九引脚( P4.4/AIN4 引脚)连接 MOS 管 Q1 的漏极;微处理器 200 的第十引脚( VSS 引脚)接地; MOS 管 Q1 的源极连接供电电池 202 的负极;触发电路 204 的电源端连接供电电池 202 的正极、接地端接地。
在本实用新型的实施例中,第二无线识别模块 201 与微处理器 200 连接,具体的第二无线识别模块 201 的数据输出端(即解码器 2014 的输出端)和微处理器 200 的一输入端 (例如第六引脚) 连接,以将数据传输给微处理器 200 。
此外,本实用新型实施例的电子烟电池杆还包括供电接口 101 ,供电接口 101 的一端( J1 端)连接供电电池 202 的正极、另一端( J2 端)连接 MOS 管 Q1 的漏极。当雾化器和电池杆连接时,供电接口 101 的 J1 端和 J2 端还分别与雾化器 30 中的电热丝 302 的两端连接,以实现给雾化器 30 的电热丝 302 供电,使其发热而雾化烟液。
本实用新型实施例中的 MOS 管还可用三极管、晶体管、晶闸管等替代以实现相同的功能。
本实用新型实施例的电子烟的工作原理为:
当雾化器 30 进入电池杆 20 的第二无线识别模块 201 的 第二 天线 2011 的工作区时(即将雾化器 30 和电池杆进行连接时),雾化器 30 内置的第一无线识别模块 301 中的第一天线 3011 接收到第二无线识别模块 201 内置的第二天线 2011 发送的电磁波,并将电磁波转换为电能以驱动第一无线识别模块 301 对存储的识别信息进行编码和调制后通过第一天线 3011 进行发送;第二无线识别模块 201 的第二天线 2011 接收包含识别信息的信号,并对该信号进行放大、解调、解码等处理后传送到微处理器 200 ;微处理器 200 根据接收到的信息判断雾化器 30 是否为相匹配的。当微处理器 200 得出判断结果(包括匹配或不匹配)时,微处理器 200 可通过控制第五脚的电压使得发光二极管 D1 的发光以进行提示。具体的,可通过控制发光二极管 D1 的发光强度或发光状态(例如闪烁、保持常亮)来分别对匹配和不匹配进行提示。另外,也可仅当匹配时控制发光二极管 D1 发光,或仅当不匹配时控制发光二极管 D1 发光。
若微处理器 200 的判断结果为雾化器 30 和电池杆 20 匹配,则当微处理器 200 接收到触发电路 204 的触发信号后,控制 MOS 管 Q1 导通,以使对雾化器 30 的供电电路导通,供电电池 202 给雾化器 30 的电热丝 302 供电。在供电过程中,微处理器 200 通过控制第四引脚输出稳定的占空比的 PWM 脉冲,控制 MOS 管 Q1 的通断,从而实现调节输出电压以对雾化器 30 的驱动方式进行调节。且在供电过程中,微处理器 200 可通过检测第九引脚的电压变化实现短路的保护。其具体实现过程为:若发生短路则第九脚检测到的电压会发生突变(电压升高),则微处理器 200 置第四引脚为低电平,使得 MOS 管 Q1 截止,从而使供电停止,实现短路保护。在供电过程中,发光二极管 D1 可指示工作状态,以及实现吸烟、停吸的淡入淡出显示。其具体实现为,微处理器 200 可通过控制第五脚的电压使得发光二极管的发光强度不同,从而指示电子烟处于正常工作状态或处于某异常的工作状态,异常的工作状态包括:短路、电池低压等;或者,通过控制第五脚的输出电压连续增大或减小,从而实现发光二极管 D1 的亮度的连续变化,实现吸烟或停吸时出现淡入和淡出的显示效果。
此外,在供电过程中,若微处理器 200 第二引脚的电平某一时间段内均处于高电平(或低电压)时,说明这段时间内一直存在触发信号,即这段时间一直处于吸烟状态,此时,微处理器 200 可控制 MOS 管 Q1 的截止,避免长时间处于吸烟状态发送烫嘴等事故,以实现长吸保护功能。在本实用新型的实施例中,这一时间段可进行设置,即可对允许的一次吸烟的时长进行控制。
若微处理器 200 的判断结果为雾化器 30 和电池杆 20 不匹配,则不管微处理器 200 是否接收到触发电路 204 的触发信号,均控制 MOS 管 Q1 截止,从而使供电电路截止。以避免给不匹配的雾化器 30 供电出现故障或口感改变等问题。
在本实用新型的实施例中,当第二天线 2011 接收到识别信息后(或微处理器 200 得出判断结果后),微处理器 200 可控制第二无线识别模块 201 终止发送电磁波,以终止第一无线识别模块 301 和第二无线识别模块 201 之间的通信连接,直到检测到(同一或另一)雾化器 30 重新与电池杆 20 连接。关于检测雾化器 30 的插拔可采用 弹片触发、机械开关触发 或采用霍尔元件进行感应检测,以确定是否为另一或同一雾化器 30 与电池杆 20 重新一次的连接。
具体的,例如,采用弹片触发的方式检测是否有雾化器 30 接入电池杆,则可将弹片触发电路与 供电接口 101 和微控制器 200 连接。当有雾化器接入供电接口时,弹片触发电路发送触发信号给微控制器 200 。微控制器 200 控制第二无线识别模块 201 发送电磁波。若设置于第二无线识别模块 301 为型号为 U2270B 的 RFID 读写器芯片 ,则微处理器 200 可通过控制其载波频率启用引脚( CFE 引脚)以实现终止第二无线识别模块 201 发送电磁波。
在本实用新型的实施例中,稳压二极管 D2 的作用为防止纹波,因为当电池电量耗完时,电池的电压会发生剧烈的改变,通过二极管 D2 可防止此时的电压剧烈改变而产生的纹波。
应理解,本实用新型实施例中的微处理器 200 采用的是型号为 Sn8P2711B 的单片机,但本领域技术人员在本实用新型的启示下,采用其他具有相同功能的单片机或 MCU 以实现本实用新型的功能也在本实用新型的保护范围之内。且任何包含本实用新型的控制电路的电子烟也均在本实用新型的保护范围之内。
参见图 5 是本实用新型实施例的电池杆对雾化器进行识别的方法流程图。该方法包括以下步骤:
步骤 S101 、 第一无线识别模块 301 预先 存储识别信息,以及 并 将所述识别信息发送给第二无线识别模块 201 。
具体的, 当雾化器 30 进入电池杆 20 的第二无线识别模块 201 的 第二 天线 2011 的工作区时(即将雾化器 30 和电池杆进行连接时),雾化器 30 内置的第一无线识别模块 301 中的第一天线 3011 接收到第二无线识别模块 201 内置的第二天线 2011 发送的电磁波,并将电磁波转换为电能以驱动第一无线识别模块 301 对存储的识别信息进行编码和调制后通过第一天线 3011 进行发送 。
应理解,若第一无线识别 201 为有源模块,则不需要接收第二识别模块 201 的电磁波,而可由其内部的电源模块自动驱动 第一无线识别模块 301 对存储的识别信息进行编码和调制后通过第一天线 3011 进行发送 。
步骤 S102 、第二无线识别模块 201 接收 到所述 第一无线识别模块 301 发送的所述识别信息 后 ,将所述接收的识别信息发送给微处理器 200 。
具体的, 第二无线识别模块 201 的第二天线 2011 接收包含识别信息的信号,并对该信号进行放大、解调、解码等处理后传送到微处理器 200 。
当第二天线 2011 接收到识别信息后,微处理器 200 可控制第二无线识别模块 201 终止发送电磁波,以终止第一无线识别模块 301 和第二无线识别模块 201 之间的通信连接。
步骤 S103 、微处理器 200 根据接收到的识别信息判断所述雾化器 30 和电池杆 20 是否匹配 。
具体的,微处理器 200 将接收到的识别信息与预存的信息进行比较,以确定接收到的识别信息是否为预存信息中匹配,若匹配则判断为雾化器和电池杆匹配,否则判断为不匹配。
本实用新型实施例的方法还包括:根据微处理器的 判断结果显示提示信息 。
具体的, 微处理器 200 可通过控制第五脚的电压使得发光二极管 D1 的发光以进行提示。具体的,可通过控制发光二极管 D1 的发光强度或发光状态(例如闪烁、保持常亮)来分别对匹配和不匹配进行提示。另外,也可仅当匹配时控制发光二极管 D1 发光,或仅当不匹配时控制发光二极管 D1 发光
本实用新型实施例的方法还包括: 当 微处理器的 判断结果为匹配且 微处理器 接收到 触发电路的 触发信号时,控制供电电路导通以使供电电池通过 所述 供电电路为所述雾化器提供供电电压 。
本实用新型实施例的电子烟具有以下优点: 电池杆可对与其连接的雾化器进行匹配识别, 可防止电子烟电池杆和非指定的雾化器混搭使用,避免消费者使用混搭却不匹配的电子烟时出现故障、口感异常等问题,使电子烟品质更安全可靠;且本实用新型的电子烟还具有各种工作状态或异常状态时的 LED 指示,显示方式可以定制、输出短路保护和长吸保护、驱动输出的电压可定制等功能。
上面结合附图对本实用新型的实施例进行了描述,但是本实用新型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实用新型的启示下,在不脱离本实用新型宗旨和权利要求所保护的范围情况下,还可做出很多形式,这些均属于本实用新型的保护之内。
