具体实施方式
为了对本发明的技术特征、目的和效果有更加清楚的理解,现结合附图详细说明本发明的具体实施方式。显然,所描述的实施例是本发明的一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明的保护范围。
第一实施例:
如图1所示,本发明提供了一种电子烟110,其包括烟嘴11、烟液腔12a、雾化装置13、供电装置15以及壳体16。所述烟嘴11的一端部与壳体16相连。所述烟液腔12a、雾化装置13以及供电装置15均设置在壳体16中。所述雾化装置13与供电装置15电性连接。所述壳体16在靠近烟嘴11的一端开设有出烟孔161。所述出烟孔161与烟嘴11连通。储存在所述烟液腔12a中的烟液可被输送至雾化装置13。所述雾化装置13由供电装置15电驱动后,加热烟液使其雾化,使使用者获得吸烟体验。
所述雾化装置13包括第一导液元件131、第二导液元件132、加热元件133、温控开关139以及雾化器座体135。所述第一导液元件131的一端与烟液腔12a连通,另一端连接第二导液元件132,用以将烟液腔12a中的烟液通过毛细作用输送至第二导液元件132。替代地,所述第二导液元件132本身直接与烟液腔12a连通(如,所述第二导液元件132包括一连通/伸入烟液腔12a的导液凸部(未图示),通过导液凸部将液体输送至第二导液元件132的其他部位),省去第一导液元件131。所述加热元件133缠绕或套设或紧贴在第二导液元件132之上。替代地,所述第二导液元件132缠绕或套设或紧贴在加热元件133之上。替代地,所述加热元件133缠绕或套设或紧贴在第一导液元件131之上,省去第二导液元件132。替代地,所述第一导液元件131缠绕或套设或紧贴在加热元件133之上,省去第二导液元件132。替代地,所述加热元件133既作为加热元件又作为导液元件,省去第一导液元件131和第二导液元件132。所述温控开关139靠近加热元件133设置,或所述加热元件133套设在温控开关139之上。所述温控开关139与加热元件133串联。所述加热元件133、温控开关139与供电装置15电性连接。所述雾化器座体135用于固定第一导液元件131、第二导液元件132、加热元件133以及温控开关139等元件中的至少一个,从而使得雾化装置13内各个元件的位置固定。
所述温控开关139具有如下性质:当温控开关139的温度ts<动作温度TM时,温控开关139闭合;当温控开关139的温度ts>动作温度TM时,温控开关139断开。考虑到所述温控开关139的温度ts略低于加热元件133的温度t,优选地,应使所述温控开关139的动作温度TM略低于所要求的加热元件133的工作温度上限TH。所述温控开关139可以是机械式温控 开关、电子式温控开关以及温度继电器中的一种、两种或两种以上的任意组合。所述机械式温控开关包括蒸汽压力式温控开关、液体膨胀式温控开关、气体吸附式温控开关以及金属膨胀式温控开关,所述金属膨胀式温控开关包括双金属片开关以及记忆合金开关。所述电子式温控开关包括电阻式温控开关以及热电偶式温控开关。所述温度继电器包括热敏干簧继电器。

在其他实施例中,所述雾化装置13可包括两个或两个以上的加热元件133和数量相同的温控开关139。所述加热元件133与温控开关139的配合关系与第一实施例中相同。可以理解地,所述加热元件133的数量与温控开关139的数量可以不匹配,但是,所述温控开关139的数量至少为一个。
在本实施例中,所述雾化装置13的结构简单、易于实现,仅通过温控开关139即可实现对加热元件133的温度t的控制。
第二实施例:
如图2所示,本发明提供了一种电子烟120。本实施例与第一实施例相比,其不同之处在于:加热元件133和温控开关139不直接串联,而是分别与一控制装置14电性连接,所述控制装置14与供电装置15电性连接。其中,所述温控开关139的性质可以为以下两种中的任意一种:一、当温控开关139的温度ts<动作温度TM时,温控开关139闭合,当温控开关139的温度ts>动作温度TM时,温控开关139断开;二、当温控开关139的温度ts<动作温度TM时,温控开关139断开,当温控开关139的温度ts>动作温度TM时,温控开关139闭合。
如图3所示,所述控制装置14包括检测电路141、处理器142以及开关电路143。随着加热元件133的温度t的升高,所述温控开关139的温度ts也升高。当温控开关139的温度ts<动作温度TM时,温控开关139发生动作A;当温控开关139的温度ts>动作温度TM时,温控开关139发生动作B。所述检测电路141与温控开关139电性连接,实时监测温控开关139的动作,并反馈给处理器142。所述处理器142根据温控开关139的动作控制开关电路143的闭合/断开。所述开关电路143与加热元件133电性连接,用于闭合/断开加热元件133和供电装置15之间的电路。其中,动作A可以是温控开关139闭合,也可以是温控开关139断开;动作B与动作A相反。

在其他实施例中,所述开关电路143可由一调节电路替代。当温控开关139发生动作A时,所述调节电路可调节供电装置15减小对加热元件133的输出电压/功率;当温控开关139发生动作B且供电装置15对加热元件133的输出电压/功率未达到最大输出电压/功率时,所述调节电路可调节供电装置15增大对加热元件133的输出电压/功率;当温控开关139发生动作B且供电装置15对加热元件133的输出电压/功率达到最大输出电压/功率时,所述调节 电路可调节供电装置15维持对加热元件133的输出电压/功率。
在其他实施例中,所述雾化装置13可包括两个或两个以上的加热元件133和数量相同的温控开关139。所述加热元件133与温控开关139的配合关系与第二实施例中相同。可以理解地,所述加热元件133的数量与温控开关139的数量可以不匹配,但是,所述温控开关139的数量至少为一个。
在本实施例中,加热元件133和温控开关139不直接串联,而是分别与一控制装置14电性连接,具有如下优点:
(1)温控开关139的选择范围更广,其性质可以为以下两种中的任意一种:一、当温控开关139的温度ts<动作温度TM时,温控开关139闭合,当温控开关139的温度ts>动作温度TM时,温控开关139断开;二、当温控开关139的温度ts<动作温度TM时,温控开关139断开,当温控开关139的温度ts>动作温度TM时,温控开关139闭合。
(2)可以通过连通/断开加热元件133和供电装置15之间的电路来调节加热元件133的温度t;还可以用调节电路替代开关电路143,通过增大/减小/维持供电装置15对加热元件133的输出电压/功率来调节加热元件133的温度t,可避免加热元件133的温度过高时立即停止工作使其温度t下降过快,进而影响使用者的使用。

所述电子烟130实现温控的过程如下:所述温敏元件134的温度T随着加热元件133的温度t的升高而升高。所述温敏元件134的电阻值R随着温敏元件134的温度T的升高而增大。所述检测电路141实时监测温敏元件134的电阻值R,并将温敏元件134的电阻值R反馈给处理器142。所述处理器142先根据温敏元件134的电阻值R与温敏元件134的温度T的对应关系数据计算出温敏元件134的温度T,然后根据加热元件133的温度t的运算公式:t=T+ΔT(ΔT:经实验所得的温敏元件134的温度T与加热元件133的温度t之间的差值)计算出加热元件133的温度t,再将加热元件133的温度t与加热元件133的工作温度上限TH和工作温度下限TL进行比较,最后根据比较结果控制开关电路143的闭合/断开。当加热元件133的温度t<工作温度上限TH时,所述处理器142控制开关电路143闭合,供电装置15向加热元件133供给电能,加热元件133的温度t升高;当加热元件133的温度t>工作温度上限TH时,所述处理器142控制开关电路143断开,供电装置15停止向加热元件133供给电能,加热元件133的温度t自然下降,直至加热元件133的温度t=工作温度下限TL时,电能供给恢复。
在其他实施例中,所述开关电路143可由一调节电路替代。当加热元件133的温度t>工作温度上限TH时,所述调节电路可调节供电装置15减小对加热元件133的输出电压/功率;当加热元件133的温度t<工作温度下限TL且供电装置15对加热元件133的输出电压/功率未达到最大输出电压/功率时,所述调节电路可调节供电装置15增大对加热元件133的输出电压/功率;当加热元件133的温度t<工作温度下限TL且供电装置15对加热元件133的输出电压/功率达到最大输出电压/功率时,所述调节电路可调节供电装置15维持对加热元件133的输出电压/功率。
进一步地,如图7所示,所述电子烟130还可包括一与所述处理器142电性连接的输入单元145。使用者可通过所述输入单元145输入所需的目标温度TD(TL≤TD≤TH)。所述处理器142将加热元件133的温度t与目标温度TD进行比较:当t<TD时,所述处理器142控制开关电路143闭合,供电装置15向加热元件133供给电能,加热元件133的温度t升高;当t>TD时,所述处理器142控制开关电路143断开,供电装置15停止向加热元件133供给电能,加热元件133的温度t自然下降。可以理解地,所述开关电路143可由一用于调节供电装置15对加热元件133的输出电压/功率的调节电路替代。
