指示灯可以为LED灯珠或者灯带,用来指示装置的工作状态,比如开机时亮起,发热件2发热时显示加热的效果图(比如跳动或者一闪一闪的火焰光效),充电状态和故障状态等。
发热件的加热过程,可以利用预设的温度曲线来控制,可以包括预热阶段和气溶胶产生阶段,不同阶段的温度要求不同,在预热阶段是逐渐将温度上升到目标温度,之后进入气溶胶产生阶段,在气溶胶产生阶段,其温度也是随着时间而渐变的(大致呈波浪或者锯齿状)。
气溶胶生成装置还包括咪头,设置在气道内,用来感应用户的吸食动作引起的气流,控制器可以根据咪头的检测结果,控制指示灯进行吸烟效果的显示,比如具有呼吸灯效果、从下往上的渐变光环(比如往上亮度越高)。
所述高频振荡电源可以从现有技术中选择高频振荡器和供电电源10配合提供高频振荡电流,在此举例不做具体限定。
气溶胶生成装置还包括充电组件,且充电组件与供电电源10连接,以便为可充电电池进行充电。采用充电的方式相比于更换电池更加简单、方便,无需将供电电源10拆卸下来。

所述气溶胶生成制品7包括设有容纳腔的装料壳体、容纳于所述容纳腔内的气溶胶基材。装料壳体包括吸食端和加热端,吸食端为使用者直接接触的作为吸嘴的一端,加热端为与发热件2连接的一端,发热件2对气溶胶生成制品7加热,形成可吸入的气溶胶,其中,基质可以为烟草、药品、植物提取物等。
使用时,涡流线圈8通电后产生高频振荡,发热件2置于涡流线圈8 产生的变化的磁场内,并产生涡旋电流,从而产生热效应,发热件2将热量传递给气溶胶生成制品7,以使得气溶胶基材受热形成气溶胶后供使用者吸食。通过设置涡流线圈8对发热件2进行涡流加热,发热件2将热量传递给气溶胶生成制品7,有效提高了加热效率,缩短了加热时间。
在本实施例中,电磁感应单元包括涡流线圈8和线圈支架12,线圈支架12位于壳体6内,具体地,所述线圈支架12设于所述上支架63内,涡流线圈8绕设于线圈支架12上,线圈支架12内设有容纳发热件2及发热件支架13的腔体。具体地,在本实施例中,通过设置线圈支架12,便于呈螺旋状的涡流线圈8的绕设。
气溶胶生成装置还包括用于支撑所述发热件2的发热件支架13,所述发热件支架13设置于线圈支架12内,所述发热件支架13采用绝缘材料制成。
所述发热件支架13内设有安装槽,所述发热件2安装在安装槽中。
可选的,所述发热件支架13的侧面设有凸台,通过所述凸台减少所述发热件支架13与其他部件的接触面积,从而进一步减少发热件2的热能损失,进一步提高了发热件2对所述气溶胶生成制品7的加热效率。所述凸台的数量可以是多个,比如,所述凸台的数量可以采用一个、两个、三个、四个、五个,在此举例不做具体限定。
可选的,所述发热件支架13采用绝缘及隔热材料制成,从而进一步减少将发热件2产生的热能传递给其他部件,进一步减少发热件2的热能损失,同时可以避免外壳发热发烫,提高了气溶胶生成装置的用户体验。
显然,以上所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例,附图中给了本发明的较佳实施例,但并不限制本发明的专利范围。本发明可以以许多不同的形式来实现,相反地,提供这些实施例的目的是使对本发明的公开内容的理解更加透彻全面。尽管参照前述实施例对本发明进行了详细的说明,对于本领域的技术人员而言,其依然可以对前述各具体实施方式所记载的技术方案进行修改,或者对其中部分技术特征进行等效替换。凡是利用本发明说明书及附图内容所做的等效结构,直接或间接运用在其他相关的技术领域,均同理在本发明专利保护范围之内。
