在一些实施例中,雾化装置还包括雾化芯16,雾化芯16用于加热并雾化雾化介质,使雾化介质受热后产生气溶胶。雾化芯16具体包括用于吸附雾化介质的多孔雾化体161,以及用于加热雾化介质的发热丝162,其中,多孔雾化体161可为刚性结构,具体可为多孔陶瓷体,发热丝162与多孔雾化体161固定连接,从而可加热由多孔雾化体161吸附的雾化介质。进一步的,雾化芯16还包括与发热丝162导电连接的引脚163,其中,引脚163一端与发热丝162连接,另一端延伸至多孔雾化体161外,从而通过引脚163使发热丝162与外界电源30导电连通,使发热丝162得电后升温,进而加热雾化介质。
在本发明中,多孔雾化体161至少包括以下两种形态,下面通过两具体实施例进行描述。
作为本发明的第一个实施例,参考图2及图3,多孔雾化体161为内部中空的圆柱状多孔雾化体,多孔雾化体161内部贯通设有使气流流通的雾化通道1611,发热丝162固定设于雾化通道1611的内侧壁上,从而在雾化通道1611上形成雾化区域。其中,雾化通道1611一端与过气孔171连通,另一端与导气管13连通,从而雾化通道1611成为气流通道的一部分。进一步的,多孔雾化体161设于多孔纤维体15的容纳孔151中,多孔雾化体161的外径在一些实施例中可略大于容纳孔151内径,从而多孔雾化体161的外壁可紧贴容纳孔151内壁设置,使多孔纤维体15内吸附的雾化介质被传导至多孔雾化体161内。用户通过吸嘴12进行抽吸时,气流经第二密封件18的进气孔181进入雾化通道1611,从而将雾化通道1611内的经加热雾化后产生的气溶胶带入导气管13,并经过气孔171进入吸嘴12内的吸气通道121,进而进入用户口腔被用户吸食。
更进一步的,在一些实施例中,多孔雾化体161朝向导气管13的一端还向另一端凹陷从而构造为限位台阶1612,用于定位安装导气管13。其中,限位台阶1612与雾化通道1611同轴设置,且限位台阶1612的外侧直径优选等于或略大于导气管13外径,导气管13的一端插设于限位台阶1612内,从而通过限位台阶1612使雾化通道1611与导气管13同轴设置,形成直通的气流通道。
作为本发明的第二个实施例,参考图4,多孔雾化体161为平板状多孔雾化体,具体的,平板状多孔雾化体可沿垂直导气管13方向延伸至储液仓14内。在一些实施例中,平板状多孔雾化体至少包括延伸至储液仓14内的导液部1613,以及设于气流通道内的雾化部1614。更进一步的,平板状多孔雾化体包括相对设置的底面1615和顶面1616,顶面1616朝向吸嘴12方向设置,在本实施例中,发热丝162盘旋设置在底面1615上,从而设有发热丝162的底面1615部分为雾化部1614,雾化部1614优选设于底面1615中心;导液部1613延伸至雾化仓22内与多孔纤维体15接触,将多孔纤维体15内的雾化介质吸附引导至雾化部1614,经过发热丝162的加热雾化,使其成为气溶胶。更进一步的,雾化部1614设于气流通道内,从而雾化产生的气溶胶可通过用户吸食,被气流带入用户口腔。
更进一步的,在本实施例中,平板状多孔雾化体具体可为扁方形,即,底面1615和顶面1616平行设置,均为长方形或具有倒角的类长方形,扁方形多孔雾化体的高度尺寸小于长方形或类长方形的长度和宽度,具体可参考图5,。在本实施例中,导液部1613沿扁方形多孔雾化体的长度方向设置在其两端,导液部1613伸入雾化仓22内与多孔纤维体15接触,发热丝162盘旋设置在扁方形多孔雾化体底面1615的中部,并将其设置在气流通道内,从而通过与多孔纤维体15接触的两导液部1613将雾化介质引导至中心的雾化部1614,经发热丝162加热后在气流通道内产生气溶胶,当用户进行抽吸动作时,气流在气流通道内流动,从而将雾化后的气溶胶带入用户口腔。
本发明还提供一种电子雾化设备,参考图6及图7,包括上述描述的雾化装置,另外,电子雾化设备还包括壳体20以及容设于壳体20内的电源30,电源30与雾化芯16导电连接,具体的,电源30通过引脚163与发热丝162导电连接,从而发热丝162的得电发热,进而加热雾化介质,产生气溶胶。
进一步的,壳体20内部中空,至少包括用于容纳电源30的电源仓21,其中,电源仓21顶部还设有隔离件40,通过隔离件40使电源30与雾化装置隔离设置。在一些实施例中,隔离件40上还设有使气流流通的若干通孔。
在一些实施例中,参考图6,壳体20与雾化装置的外壳11一体设置,即壳体20与外壳11固定连接,使电子雾化设备成为一不可分割的整体。
在另一些实施例中,参考图7,壳体20还包括用于容纳雾化装置的雾化仓22,雾化仓22和电源仓21之间通过隔离件40进行隔离,雾化仓22顶部为敞口,雾化装置自敞口插设在雾化仓22内,从而使雾化装置与壳体20可拆卸连接。
本发明提供的雾化装置,通过将多孔纤维体15填充至储液仓14中,能够有效避免储液仓14的漏油现象;同时,多孔雾化体161与多孔纤维体15接触,保证雾化介质能够被吸附传导至多孔雾化体161上被雾化,多孔雾化体161良好的强度条件使得其不易变形,故而能够有效避免雾化芯16在工作过程中由于温度不均匀导致的糊芯现象,同时,其便于装配,节省人力成本,同时能够在提升装配效率的同时,改善装配质量。
以上实施例仅表达了本发明的几种实施方式,其描述较为具体和详细, 但并不能因此而理解为对发明专利范围的限制。应当指出的是,对于本领域的普通技术人员来说,在不脱离本发明构思的前提下,还可以做出若干变形和改进,这些都属于本发明的保护范围。因此,本发明专利的保护范围应以所附权利要求为准。
