具体实施方式
本发明的电池杆设置有可与外部设备连接的电源输出接口，电池杆内的电池可以通过电源输出接口为外部设备供电，因此，当电子烟的烟油已经用完，但是电池还有充足的电量时，可以通过电源输出接口连接外部设备，有效利用完电子烟中的电池，或者外部设备正好需要应急电源时，可以通过电源输出接口将电子烟中的电池用作应急电源。因此，本发明的电池杆能简单有效利用电子烟的电池，充分利用能源，减少能源的浪费，且本发明的电池杆仅在没有给雾化器供电时才允许为外部设备供电，减小了外部设备的用电给电子烟的工作带来的干扰，本发明还设置电池保护电路，避免外部电源误接到电源输出接口，对电池杆内部电池进行充电损坏电池。
为了对本发明的技术特征、目的和效果有更加清楚的理解，现对照附图详细说明本发明的具体实施方式。
参考图1-4，图7-9，本发明的电池杆，用于与雾化器组合形成电子烟，所述电池杆包括电池套管1和沿电池套管1轴向设置的电池2及设置有用于控制电池2给所述雾化器供电的电路的第一电路板3，所述电池杆上还设置有用于与外部设备连接的电源输出接口7，第一电路板3上设置有与电源输出接口7及电池2电连接的供电控制电路10，所述供电控制电路10用于根据是否接收到吸烟触发信号阻止或允许所述电池2通过所述电源输出接口7为外部设备供电。
电池套管1大致为中空的圆筒状结构，实施例一中，第一电路板3上焊接有按键开关8，按键开关8用于触发雾化器工作。可以理解的是，所述按键开关8可以为设置在所述电池杆的气流通道上的气流传感器。
参考图11A，所述供电控制电路10包括微处理器U1及与所述微处理器U1相连的开关器件，所述开关器件与电池2及所述电源输出接口7相连。所述开关器件可以为三极管、场效应管或继电器等。具体地，在本实施例中，所述微处理器U1的型号为SN8P2712，开关器件为P型的MOS管Q1， MOS管Q1的栅极连接至微处理器U1， MOS管Q1的源极连接至电池2的正极， MOS管Q1的漏极连接至电源输出接口7的一端，电池2的负极和电源输出接口7的另一端连接。可以理解的是，MOS管Q1只需连通电池2和电源输出接口7以形成一个完整的导电通路即可，因此，也可以将电池2的正极和电源输出接口7的一端连接， MOS管Q1连接在电池2的负极和电源输出接口7的另一端之间， MOS管Q1也可以是N型，或者将MOS管Q1用三极管替代。
如果有吸烟触发信号，比如按键开关8按下或者气流传感器感应到气流信号，微处理器U1控制电池2通过电压调整模块给所述雾化器供电，同时微处理器U1输出高电平至MOS管Q1的栅极，从而控制MOS管Q1处于截止状态以断开电池2和电源输出接口7的电连接，进而阻止电池2通过电源输出接口7为外部设备供电，因此，即使电源输出接口7连接上外部设备，也不会为外设供电，减小了外部设备的用电给电子烟的工作带来的干扰。如果没有吸烟触发信号，微处理器U1输出低电平至MOS管Q1的栅极，从而控制MOS管Q1处于导通状态，电池2和电源输出接口7的电连接通路导通，一旦电源输出接口7连接上外部设备，即可实现电池2通过电源输出接口7为外部设备供电。
为了避免外部电源误接到电源输出接口7，对电池2进行充电而损坏电池2，优选的，参考图11B，第一电路板3上还设置有与电源输出接口7电连接并能够阻止外部电源通过电源输出接口7对电池2充电的电池保护电路20。在本实施例中，所述电池保护电路20包括二极管D1，所述二极管D1的正极电连接至所述电池的正极，所述二极管D1的负极与所述电源输出接口7电连接。
更具体的，二极管D1的正极与MOS管Q1的漏极连接，二极管D1的负极与电源输出接口7的一端连接。如果电源输出接口7被接入外部电源，则二极管D1反向截止，断开电源输出接口7与电池2之间的电连接，避免外部电源对电池2误充电而导致可能损坏电池2。当然二极管D1可以串联连接在供电回路的任一位置，比如连接在电源输出接口7和电池2之间，或者连接在MOS管Q1和电池2之间。本实施例所述的电池保护电路20结构简单，成本低。可以理解的是，所述电池保护电路20也可以用其它电源管理芯片实现。
电池杆还包括设置在电池套管1远离第一电路板3一端的端盖5，端盖5与电池套管1的连接包括过盈配合、螺纹连接、扣合连接等，优选为过盈配合。端盖5上开设有安装口，为了便于固定电源输出接口7，优选的，所述电池2远离第一电路板3的一侧设置有第二电路板4，第一电路板3平行于电池套管1轴向安装，第二电路板4垂直于电池套管1轴向安装，电源输出接口7沿轴向或者径向固定焊接在所述第二电路板4上且从所述安装口裸露出来。上述供电控制电路10也可以改为设置在第二电路板4上，如此则增加了第二电路板4的焊接工艺，但第一电路板3可以直接利用现有技术中的电路板。另一方面，还可以在第二电路板4上设置相关的供电电路，比如升压电路、过流过压检测等，以保护电池2。
可以理解的是，电源输出接口7对应的安装口并不一定是设置在端盖5上，也可以是直接开设在电池套管1上，本发明优选为开设在端盖5上，一方面在组装电池杆时比较方便，另一方面充分利用了现有电池杆中端盖5的内部空间，不会增加电池套管1的长度。
其中，所述电源输出接口7包括mini USB电源输出口和通用型电源输出口，且不限于上述电源输出接口。
需要利用电池杆对外部设备供电时，将外部设备插接到电源输出接口7即可，简单方便，由于现在大多数电源输出接口都是mini USB电源输出口或者通用型电源输出口，利用该电池杆对外部设备供电时通用性强。且本发明的电源输出接口7通过设置在端盖5上的安装口裸露出来，不用拆卸出电池就可将电池杆中的电池通过电源输出接口7为外部设备供电。
电池杆给雾化器供电的方式是通过电池杆与雾化器的螺纹连接处的电极连接件实现，本发明的电池杆即使其连接上雾化器组成电子烟，如果用户没有吸烟动作，不用拆卸雾化器，可以直接将电子烟与外部设备插接上作为供电电源。且电源输出接口7从端盖5的安装口裸露出来，没有增加额外的空间结构，不会影响电子烟的美观，充分利用了电池杆的空间，结构简单，组装非常方便。
实施例一：
实施例一中，电源输出接口7沿轴向固定焊接在第二电路板4，本实施例中电源输出接口7为mini USB电源输出口，当然也可以将通用型电源输出口替换mini USB电源输出口。
参考图1-5，端盖5包括盖体54和沿盖体54缩径形成的、朝向电池套管1轴向延伸的中空的连接部55，电池套管1套设在连接部55上，盖体54盖设在电池套管1上。
第二电路板4为圆盘结构，电源输出接口7沿轴向固定焊接在第二电路板4朝向盖体54的端面上。安装口为盖体54沿电池套管1轴向开设的安装孔51，电源输出接口7与安装孔51相匹配并沿轴向穿过安装孔51后与盖体54的外表面形成平整的表面。
优选的电源输出接口7焊接在第二电路板4的中心位置，安装孔51的中轴线与电池套管1的中轴线对齐设置，设置在中心位置在电源反复插拔的过程中，第二电路板4受力均匀，不易出现因施力不均导致第二电路板4倾斜的缺陷。
可以理解的是，第二电路板4可以通过与电池套管1过盈配合实现固定，考虑到电源输出接口7与外部设备之间的插拔频率比较高会使第二电路板4出现松动移位，因此，优选的，连接部55内壁形成用于抵持第二电路板4朝向盖体54的端面的第一内凸缘551，如此在施力将外部设备从电源输出接口7拔出时，第一内凸缘551抵持住第二电路板4，以便于外部设备拔出。对应的，在外部设备插入时，第二电路板4朝向电池2的端面需要被抵住，因此，电池杆还包括设置在第二电路板4远离盖体54一侧的紧固件6，紧固件6与第二电路板4朝向电池2的端面相互抵持，连接部55套设于紧固件6上，连接部55与紧固件6的连接，可以为螺纹连接、扣合连接、过盈配合等，优选为过盈配合，结构设计简洁，组装简单。
参考图5，还可以在紧固件6内壁形成第二内凸缘61，第二电路板4与第二内凸缘61相互抵持，即第二电路板4夹持在第一内凸缘551和第二内凸缘61之间。为此，第二内凸缘61到紧固件6朝向盖体54的端面的距离小于等于第二电路板4的厚度，优选为两者相等，即紧固件6朝向盖体54的端面与第二电路板4朝向盖体54的端面共同抵持在第一内凸缘551上，如此使得结构更加紧固。
紧固件6中间开设有供导线穿设的通孔62，因为外部设备电源接头插拔时会给第二电路板4施加力，因此优选圆形通孔62，如此紧固件6抵持第二电路板4的端面受力分布均匀，圆形通孔62直径必须比第二电路板4的外径小，考虑到尽可能的减轻述紧固件6的重量，优选圆形通孔62的直径仅比第二电路板4的外径小2mm。
实施例二：
实施例一中的轴向固定适合mini USB电源输出口和通用型电源输出口，电源输出接口7还可以沿径向固定焊接在第二电路板4朝向盖体54的端面上，由于mini USB电源输出口的端面为水平面，所以径向设置时与电池套管1的表面不能形成光滑过渡，因此径向设置适合通用型电源输出口。实施例二中的电源输出接口7为通用型电源输出口。
具体的，安装口为连接部55自朝向电池2的一端起沿轴向开设的第一缺口52，电池套管1自朝向端盖5的一端起沿轴向开设有第二缺口11，第一缺口52和第二缺口11在电池套管1的径向方向上相对设置形成用于容纳电源输出接口7的容纳空间。
与实施例一不同的在于，此时的电源输出接口7是通过两个缺口限定位置的，采用缺口主要是在组装时，首先将第二电路板4沿轴向推入端盖5中，此时电源输出接口7对准第一缺口52并推入，电源输出接口7朝向盖体54的侧面抵持在第一缺口52的底部，紧接着在将端盖5推入电池套管1时，电源输出接口7对准第二缺口11并推入，电源输出接口7远离盖体54的侧面抵持在第二缺口11的底部。
实施例二中，电源输出接口7部分伸出第二电路板4的边缘并依次穿过第一缺口52和第二缺口11后与电池套管1形成光滑过渡的表面。
本发明还提供一种电子烟，参考图6和10，电子烟包括雾化器和上述电池组件。
连接上雾化器后，雾化器的工作必须优先执行，当有吸烟触发信号时，比如按键开关8按下时，第一电路板3导通电池2与雾化器之间的电连接，以驱动雾化器产生烟雾，此时，尽管电源输出接口7连接上外部设备，第一电路板3中的供电控制电路控制电池不对外供电，断开电池与电源输出接口7的电连接；当没有吸烟触发信号时，比如按键开关8打开时，第一电路板3断开电池杆与雾化器之间的电连接，此时如果电源输出接口7连接上外部设备，第一电路板3导通电池2与第二电路板4之间的电连接，实现对外供电。
参考图12，本发明还提供一种电子烟的供电方法，包括雾化器，还包括上述的电池杆，所述供电方法包括如下步骤：
S1、将所述电池杆与所述雾化器连接；
S2、供电控制电路10判断是否接收到吸烟触发信号，若是，则转步骤S3，否则，转步骤S4，
S3、供电控制电路10控制电池2给所述雾化器供电并阻止电池2通过电源输出接口7为外部设备供电；
S4、供电控制电路10控制电池2断开给所述雾化器供电并允许电池2通过电源输出接口7为外部设备供电。
所述方法还包括：
如果外部电源连接到电源输出接口7，电池保护电路20阻止所述外部电源通过电源输出接口7对电池2充电。
综上，通过在电池杆设置可与外部设备连接的电源输出接口，电池杆内的电池可以通过电源输出接口为外部设备供电，因此，当电子烟的烟油已经用完，但是电池还有充足的电量时，可以通过电源输出接口连接外部设备，有效利用完电子烟中的电池，充分利用能源，减少能源浪费；或者外部设备正好需要应急电源时，可以通过电源输出接口将电子烟中的电池用作应急电源，因此，本发明的电池杆通过增加电源输出接口，能简单有效利用电子烟的电池，且本发明的电池杆仅在没有给雾化器供电时才允许为外部设备供电，减小了外部设备的用电给电子烟的工作带来的干扰。
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。
