使用时,空气从第二管段112远离第一管段111的一端进入,由于第一发热体121是螺旋设置在第二管段112外壁上的,因此,第一发热体121通过热传导将热量传递至第二管段112的内壁上时,热量形成呈螺旋状的分布不均匀的热量路径,进而在第二管段112内部通过螺旋状的热量路径对空气加热,从而形成螺旋上升气流,通过导气孔101进入第一管段111内加热烟支。

本实施例中的发热组件包括第五发热体132;第五发热体132安装在管体11内,且气流分配件27位于第五发热体132的上方,第五发热体132加热的空气通过第一穿孔207和第二穿孔208导出。
值得一提的是,本申请的分流板271相当于其他实施例的导气层14,本申请的第二导气管272相当于其他实施例的第一导气管141。
本发明的气流分配件27通过第二导气管272和第二穿孔208将热空气分成两部分气流,第二导气管272可插入烟支60内部,由第二导气管272导出的热气流对烟支60的内部进行加热,未与第二导气管272对接的其余第二穿孔208导出的热气流对烟支60的底部进行加热,使烟支60的底部和内部能够同时进行加热并产生气溶胶,提高烟支60的加热效率,烟支60的受热更均匀,使用者的抽吸口感更加饱满。

本实施例中,如图38、图39和图40所示,本实施例加热不燃烧烟具与上述实施例的加热不燃烧烟具的区别在于,本实施例的发热组件的结构不同。第六发热体134可以是发热丝式的,或者图层式的,或者线路式的。具体地,第六发热体134为发热丝式的(如图38所示):第六发热体134的侧壁上开设有发热通孔,发热通孔沿第六发热体134的轴向方向开设,这样通过在第六发热体134上设置发热通孔,能够增大第六发热体134与进入加热腔中的空气的接触面积,提高较热速度。第六发热体134为涂层式的(如图39所示):通过在第二导热管133外壁涂覆能够发热的材料形成发热片,发热片贴附于第二导热管133,材料可以选用石墨。第六发热体134为线路式的(如图40所示):第六发热体134的侧壁上开设有发热通孔,发热通孔沿发热体周向方向开设,从外观上看如同多个发热线圈间隔连接设置形成的第六发热体134。可以根据不同的情况下制定不同形式的发热体,在此不再加以赘述。
第六发热体134的热可以通过第二躯段1332迅速将热量带走,一方面避免热量集中散布出去,导致第六发热体134温度过高造成热量集中在主体部分或者引脚线上,导致第六发热体134损坏;另一方面,由于热量可以及时导走,且第二导热管133采用空心管,其本身热容较小,可以提高热量的利用率,使尽量多的热量往烟支上传递。
本实施例中,底板28上连接有安装块281和支撑件282,底板28连接于第二管段112的底部,第二导热管133的一端连接于安装块281。
本实施例中,至少第二躯段1332朝向第六发热体134的表面涂覆有电绝热层。
第十九实施例
请参阅图41至图43,本实施例加热不燃烧烟具与上述实施例的加热不燃烧烟具的区别在于,本实施例中的发热组件的结构不同。导气层14设置在第一管段111与第二管段112的拼接处,导气层14的上方为导热通道209,导气层14的下方为热气形成腔304,导气层14的导气孔101连通导热通道209和热气形成腔304。
发热组件安装在热气形成腔304中,发热组件包括第三导热管136和第七发热体137。第三导热管136上下延伸,第三导热管136设于热气形成腔304并设有上述实施例的螺旋凸起135,螺旋凸起135将热气形成腔304分割形成螺旋导流通道,螺旋凸起135包括上下布置的第一螺旋段1351和第二螺旋段1352,第一螺旋段1351的螺距小于第二螺旋段1352的螺距。
第七发热体137绕设与第三导热管136上并沿螺旋导流通道延伸,第七发热体137在通电时能够加热螺旋导流通道的空气。
在本实施例中,通过将第七发热体137在更靠近导热通道209的第一螺旋段1351缠绕得更密集,使第七发热体137在更远离导热通道209的地方设置得较为疏密,对热气形成腔304内的空气进行初步加热,再在靠近导热通道209的地方设置得更为密集,对热气形成腔304内的空气进一步加热,加热后的空气传递至导热通道209,将热量传入导热通道209的烟支,从而缩短主要用于对烟支加热的热气流传递至烟支的路程,尽可能地减少热气流在传递过程中的热流失和热损耗,实现热利用率的提高和能耗的降低。
具体地,如图41所示,在本实施例中,管体11的第二管段112包裹第三导热管136,第一管段111内部形成导热通道209,第二管段112内部形成热气形成腔304。通过第一管段111和第二管段112的高度设置,限定导气层14的位置,确定导热通道209和热气形成腔304的空间比例。
其中,第一管段111和第二管段112可为一体设置,也可不为一体设置,具体地,一体设置指同一材质一体加工成型或两个结构固定连接成一体,通过第一管段111和第二管段112设置为一体设置,可节省两者的制造成本。在其他实施例中,当第一管段111和第二管段112不为一体设置时,则能够分别针对第一管段111和第二管段112分别做出差别改进的设置,此时第一管段111和第二管段112可通过套合连接,或采用焊接等方式进行固定连接。
此外,如图41和图43所示,在本实施例中,加热不燃烧烟具还包括盖板33和底座34,盖板33设有第三开口308供出气和供烟支放入导热通道209;底座34设有进气口309并起支撑作用,外壳24的顶部与盖板33连接,外壳24的底部与底座34连接,外壳24将电路板31、电源16包裹在内,通过电极15将电源16、电路板31与第七发热体137连接以进行通电。
加热不燃烧烟具的具体工作过程:电源16供电,并经电路板31、电极15对第七发热体137进行通电,空气沿进气口309从底部进入第二管段112内部的热气形成腔304,然后沿螺旋导流通道上升,第七发热体137通电后,对上升至螺旋导流通道底部较为远离导热通道209处的空气进行初步加热,再对上升至螺旋导流通道顶部较为靠近导热通道209处的空气进一步加热,空气经第七发热体137加热后成为热气流,热气流从热气形成腔304沿较短的路径穿过导气孔101进入导热通道209,对事先从第三开口308置入导热通道209内的烟支进行加热。
具体地,本申请中的烟支可以是烟草材料,草本材料,药用材料或者其他可加热产生气溶胶的材料。
如图42所示,作为一种实施方式,第一螺旋段1351在与第三导热管136连接点处的升角相同,为第一升角,第二螺旋段1352在与第三导热管136的连接点处的升角相同,为第二升角,第一升角小于第二升角。
本实施例中,第一螺旋段1351在与第三导热管136连接点处的升角相同为第一升角,第二螺旋段1352在与第三导热管136的连接点处的升角也相同为第二升角,且第一升角小于第二升角。
此时因为第一螺旋段1351的螺距比第二螺旋段1352的螺距小,所以第一螺旋段1351在第三导热管136外壁的缝隙比第二螺旋段1352在第三导热管136外壁的缝隙要小,而第七发热体137是沿第一螺旋段1351和第二螺旋段1352在第三导热管136外壁的缝隙,缠绕在第三导热管136外壁的,当在每段缝隙缠绕次数相等时,在同等轴向范围内,第七发热体137沿第一螺旋段1351在第三导热管136外壁的缝隙,缠绕得比在沿第二螺旋段321在第三导热管136外壁的缝隙密集,从而达到让第七发热体137更集中分布在靠近导热通道209处的目的,以更快更集中地对导热通道209内的烟支加热,并实现缩短主要热量的传递路程从而减少热损失和热损耗的技术效果。
在其他实施例中,第一螺旋段1351在与第七发热体137的连接点处的升角为第一升角,第一升角向上递减;和/或,第二螺旋段1352在与第七发热体137的连接点处的升角为第二升角,第二升角向上递减。本实施例不同的是,第一螺旋段1351和第二螺旋段1352在第三导热管136外壁的缝隙,比原实施例更为窄小,第七发热体137沿更为窄小的缝隙也会缠绕得愈发密集,进一步使第七发热体137向导热通道209的方向集中螺旋和更密集的分布,增强了原实施例中表现出的技术效果,进一步了缩短主要热量传递路程以减少热损失和热损耗。
在其他实施例中,也可以通过令第七发热体137自下而上增加缠绕的圈数,以达到缩短主要热量传递至容置腔的烟支的路程的目的,而且可以与本实施例或原实施例同时应用,从而进一步增强原有的技术效果。
作为一种实施方式,第三导热管136沿螺旋导流通道开设有供第七发热体137置入的凹槽。
具体地,通过在第三导热管136外壁沿螺旋导流通道设置螺旋凹槽,对第七发热体137进行安装,可起到对第七发热体137固定和限位的作用。
如图42所示,作为一种实施方式,第三导热管136设有尖锥状结构的椎体138,椎体138穿过导气孔101延伸至导热通道209。
具体地,尖锥状结构的椎体138设置在第三导热管136靠近导热通道209的端面,通过焊接等方式固定在该端面。具体地,通过设置尖锥状结构的椎体138,利用尖端热效应,实现更集中迅速地将热气形成腔304内的热气流携带的热量,传递至导热通道209的烟支内的技术效果。
其中,如图42所示,导气孔101包括孔径较大的供椎体138穿过并延伸至导热通道209的第一气孔1011,和孔径较小的供热气流穿过并进入导热通道209的第二气孔1012。
如图42所示,作为一种实施方式,第三导热管136开设有第一孔洞306,第一孔洞306沿第三导热管136的轴向延伸且贯穿其两端,第三导热管136靠近导热通道209的一端的侧壁上开设有第二孔洞307,第二孔洞307和第一孔洞306相连通,第七发热体137的一端从第二孔洞307伸入第一孔洞306内,再与从进气口309伸入并延伸至第一孔洞306的一电极15相连;
第七发热体137缠绕在第三导热管136外壁的另一端,与从进气口309伸入热气形成腔304的另一电极15相连。
本实施例中,第七发热体137从第三导热管136外壁底部开始,沿螺旋导流通道缠绕至第三导热管136 外壁顶部,然后经第二孔洞307延伸至第三导热管136的第一孔洞306内,第七发热体137的一端在第三导热管136的第一孔洞306内,另一端在第三导热管136外壁底部。电极15从第二管段112底部伸入热气形成腔304内,延并伸至第三导热管136外壁底部与第七发热体137的另一端相连,第二导线35从第二管段112底部伸入第一孔洞306内部与第七发热体137的一端相连,使第七发热体137从开始的一端到结束的一端都与电源16连通,在电源16供电时能够使第七发热体137整体通电发热。
第二十实施例
请参阅图44至图49,本实施例加热不燃烧烟具与上述实施例的加热不燃烧烟具的区别在于,本实施例中的加热不燃烧烟具包括多个发热组件,多个发热组件相互间隔分布,能够起到上述实施例中成倍的加热效果,提升加热效率。
如图48所示,多个发热组件的第七发热体137之间采用并联连接。 在本实施例中,每个发热组件的第七发热体137分别通过一电极15连接至第一电极板311,再分别通过另一电极15连接至第二电极板312,然后通过第一电极板311和第二电极板312与电路板31相连,最后通过电路板31与电源16相连,从而实现每个发热组件的第七发热体137在电路上的并联连接,使电源16能够对并联电路上的每个发热组件的第七发热体137通电。
如图45至图49所示,加热不燃烧烟具包括具有多个装配孔401的圆柱状结构体32,每个装配孔401内分别形成独立的热气形成腔304,每个发热组件分别置入一个装配孔401内。
本实施例中,与原实施例不同的是,原本中空的第二管段112被替换成具有多个装配孔401的圆柱状结构体32,再将多个发热组件的每个分别设置在一个装配孔401内,使每个装配孔401内形成独立的热气形成腔304。
多个发热组件在通电后,分别对其所在装配孔401内的热气形成腔304的空气进行独立加热,加热后的空气分别经导气孔101共同汇聚到导热通道209内,对导热通道209内的烟支进行加热。
在本实施例中,每个装配孔401内部形成独立的热气形成腔304,每个发热组件都分别在独立的热气形成腔304形成螺旋导流通道,在实现原实施例中设有单个发热组件的技术效果的同时,还能通过汇聚每个发热组件独立加热后的空气,增强对容置腔102内烟支的加热效果。
在其他实施例中,通过对电路板31、电源16等电源装置进行设置,可实现对多个发热组件中的单个发热组件实行单独的通电开关控制,从而控制单个发热组件或者多个发热组件一起工作,进而加热某一特定区域的烟支。
如通过控制中心区域的发热组件先进行通电加热,当中心区域的颗粒耗尽时,再控制周围的发热组件通电加热,实现更为合理均衡的加热效果。
又比如,通过控制某一区域的发热组件集中通电对烟支加热,又或者其余区域的发热组件先进行通电预热,通过针对烟支的位置进行精准加热,可以实现节省能耗的效果。
作为一种实施方式,多个发热组件绕所述圆柱状结构体32的中心轴线的周向呈同心圆分布。
具体地,通过将装配孔401设置得绕所述圆柱状结构体32的中心轴线的周向呈同心圆分布,便能使所有发热组件绕所述圆柱状结构体32的中心轴线的周向呈同心圆分布,使发热组件呈现较为均匀分布,使每个发热组件加热后形成的热气流均衡地汇聚到容置腔102,从而达到对容置腔102内烟支均衡加热的效果。
在其他实施例中,多个发热组件可呈现其他均匀间隔的分布方式,如矩形点阵分布或三角形点阵分布等。
本发明提供的加热不燃烧烟具,通过在第三导热管136外壁设置螺旋凸起135,利用螺旋结构将热气形成腔304分割形成绕第三导热管136周向并向上延伸的螺旋导流通道,同时将螺旋凸起135分为第一螺旋段1351和第二螺旋段1352,并使第一螺旋段1351的螺距小于第二螺旋段1352,从而使第七发热体137在更靠近导热通道209的第一螺旋段1351附近,沿所述螺旋导流通道延伸缠绕得更密集,从而使第七发热体137先对远离导热通道209的热气形成腔内的空气进行初步的加热,再在空气流动至靠近导热通道209时对空气进行主要的加热,然后使经过主要的加热的空气经过较短的路程传递至导热通道209,最后空气再将热量传入导热通道209的烟支,通过缩短经过主要加热后的热气流传递至烟支的路程,从而尽可能减少热气流在传递过程中的热流失和热损耗,使热量主要用于对烟支加热,实现空气加热式烟具的热利用率的提高和能耗的降低;此外,还可以通过设置多个发热组件同时对空气进行加热,以提升加热效果和提高加热效率。
第二十一实施例
请参阅图50至图53,本实施例加热不燃烧烟具与上述实施例的加热不燃烧烟具的区别在于,本实施例中的发热组件的结构不同,发热组件包括第八发热体139,第八发热体139包括置于导热通道209的第一加热段1391和置于热气形成腔304的第二加热段1392,第二加热段1392在接电时加热热气形成腔304的空气,第一加热段1391在接电时能够加热位于导热通道209的烟支。
本实施例中,将烟支放入导热通道209,空气从进气口309进入到热气形成腔304,然后使第八发热体139通电加热,第八发热体139通电加热后,第八发热体139的第二加热段1392对热气形成腔304的空气加热形成热气流,热气流穿过导气层14的导气孔101进入导热通道209对烟支加热,同时,第八发热体139的第一加热段1391也对导热通道209的烟支进行接触式热传导的加热。
通过第八发热体139通电加热产生热气流对烟支加热并直接对烟支进行周向加热,能够实现对烟支的均匀加热,同时由于热气流进入导热通道209后,其热量被烟支和第八发热体139的第一加热段1391吸收利用,减少了热气流的热量损失,则降低了空气加热的能量损耗,因此本发明提供的烟支能够在实现均匀加热的同时降低了能耗损失,并充分利用第八发热体139通电加热产生的热量,有效提高了热量利用率。
具体地,本发明的加热不燃烧烟具主要用于对烟支进行加热雾化,其中烟支指能够在经加热后雾化呈微小颗粒并经人吸食而作用于口咽部、气道和肺部的物料,包括烟丝、烟草或撕碎后的烟支等。
管体11由铜铝合金或者包含碳纤维或氮化铝纤维的陶瓷制成。
具体地,可由铜、铝金属或者其金属合金或者硅多孔制成,又或者是由加入导热纤维的导热陶瓷制成,其中,纤维可以为碳纤维,铜、铝金属纤维、或氮化铝纤维,纤维含量在30%以下,而陶瓷基体可以为氮化铝,氧化铝,氮化铝,不锈钢,通过这些材料的高导热特性能够实现管体11良好的加热效果,而且当碳纤维或氮化铝纤维的陶瓷制成管体11时,还能利用碳纤维或氮化铝纤维良好的电绝缘性,避免第八发热体139通电时出现漏电的现象。
第八发热体139外设有第二绝缘层35包裹。
具体地,通过设置第二绝缘层35,避免第八发热体139与空气、烟支、烟丝、烟草等接触时出现短路和漏电的现象。
其中,第二绝缘层35可采用喷涂、电镀、固定连接安装等方式设置在第八发热体139外,同时第二绝缘层35可采用硅橡胶、氮化镁等导热性和绝缘性都十分良好的材料制成。
在本实施例中,第八发热体139可由钛,镁,铬,铜,钴、铬、铝、钛、锆、铪、铌、钼、钽、钨、锡、镓、锰,镍、铁金属或者其的合金、不锈钢、或碳制成,利用这些材质主要出于实现加热件绝缘和加热的效果。
导气层14与第八发热体139可拆卸连接。
具体地,导气层14与第八发热体139为可拆卸连接可通过更换具有不同孔径的导气孔101,调节热气流流入导热通道209的速度,从而调节对烟支加热的速度。
在本实施例中,导气层14开设有与第八发热体139配合的安装孔402。
具体地,导气层14通过开设有与第八发热体139相适配的安装孔402,即可让导气层14沿第八发热体139的轴向套入或取出,从而实现导气层14与第八发热体139的可拆卸连接。
如本实施例中,第一加热段1391和第二加热段1392,沿延伸方向的截面都是螺旋状,则让导气层14开设出与第二加热段1392和第一加热段1391横截面相对应的安装孔402,安装孔402为螺旋通槽,则可将导气层14沿第八发热体139的轴向套入或取出。
本实施例中,第八发热体139插接导气层14后,第八发热体139和导气层14整体置于管体11内,管体11的筒壁设有限位件,在第八发热体139和导气层14整体置于管体11时,限位件避让第八发热体139的置入,并抵接导气层14而限制导气层14向背离进气口309方向的移动。换言之,限位件用于对导气层14限位,而定位了导气层14的装配位置。
第一管段111内部形成导热通道209,第二管段112内部形成热气形成腔304,导气层14夹设于第一管段111和第二管段112之间。通过第一管段111和第二管段112的高度设置,限定导气层14在管体11内的位置,确定导热通道209和热气形成腔304的空间比例。
在本实施例中,导气层14由钛、镁、铬、铜、钴、铬、铝、钛、锆、铪、铌、钼、钽、钨、锡、镓、锰,镍铁、或金属合金、或不锈钢制成。
第二加热段1392和第一加热段1391均为片状,并沿从热气形成腔304至导热通道209的方向延伸。具体地,第二加热段1392和第一加热段1391均为片状有利于增大发热面积,其中,因为第一加热段1391直接与烟支接触,所以通过将第一加热段1391设置成片状,有利于将烟支包裹在内进行周向均匀加热,并提高加热效率。
在其他实施例中,第二加热段1392和第一加热段1391也可以为空心结构体状,包括空心圆柱体、空心长方体等。
此外,第二加热段1392和第一加热段1391沿从热气形成腔304至导热通道209的方向延伸,尽可能使第二加热段1392和第一加热段1391分别在热气形成腔304和导热通道209的径向范围延伸,从而扩大加热范围,提升热效率。
在本实施例中,第二加热段1392沿其延伸方向的截面为螺旋状并从热气形成腔304的中心向外螺旋。
通过将第二加热段1392在为片状的基础,设置成螺旋结构,更有利于充分利用增大的发热面积和扩大加热空间,进而提升加热不燃烧烟具对烟丝、烟草或烟支等的加热效率。
在其他实施例中,第二加热段1392除设置成螺旋状的结构外,也可考虑设置其他能够合围成内部加热空间,以对进入其内的空气进行加热的结构,如矩形体结构、圆柱体结构等。
第一加热段1391沿其延伸方向的截面为螺旋状,且其与第二加热段1392在截面投影上重合。
本实施例中,第二加热段1392和第一加热段1391一体设置。第一加热段1391为螺旋状,且其与第二加热段1392在截面投影上重合,换言之,第八发热体139整体为从热气形成腔304向导热通道209方向延伸的片状,并呈沿中心向外展开的螺旋状。导气层14套设在第八发热体139上,而将第八发热体139分隔形成导热通道209和热气形成腔304。
螺旋状的第一加热段1391将导热通道209的空间内分隔形成多个加热空间,第一加热段1391对各加热空间进行大面积的加热而有利于提高加热效率。第一加热段1391与第二加热段1392在截面投影上重合,一方面,能够简化结构降低成本,另一方面,空气从热气形成腔304到导热通道209的路径通道具有延续性,不被阻挡、分隔而有利于热量的快速流通。
在其它实施例中,第一加热段1391也可以为多个间隔设置的加热片,加热片截面为矩形或弧形。多个加热片顺次连接形成圆形,或者,多个加热片呈行列分布。
在其它实施例中,第一加热段1391为螺旋片状,但其螺线不与第二加热段1392重合。第一加热段1391沿延伸方向的截面为螺旋状,其螺线与第二加热段1392均为阿基米德螺线,但起始位置不同或螺旋方向相反。或者,第一加热段32的螺线形状与第一加热段1391不同。
第二加热段1392在中心端部和外围端部分别引出电极15以通电。
因为当第二加热段1392的截面为螺旋状并从热气形成腔304的中心向外螺旋时,其在从热气形成腔304中心开始向外螺旋的端部设有一条电极15,并在向外螺旋至最外部末端的端部设有另一条电极15,通过这两电极15分别连接电源16正负极,即可使得第八发热体139整体充分通电并避免短路的情况发生。
具体地,第八发热体139为由中心向外扩展的螺旋片状,包括两个分别与两个电极15连接的连接部,其一完全覆盖第八发热体139中心端的片沿,另一连接部完全覆盖第八发热体139的外围端的片沿,两个连接部之间为电流的流通区域。两个连接部分别位于第八发热体139的两端侧在第八发热体139尺寸固定的情况下,能够有效增加电流的流通长度。两个连接部完全覆盖第八发热体139端侧的边沿,从而有效增加电流场的宽度。因此,两个连接部完全覆盖第八发热体139的两端侧的边沿能够有效增加电流场的覆盖面积,从而增加第八发热体139与空气的接触面积而提高换热效率,而且通过在第二加热段1392下部引出连接部,也可充分利用进气口309 的空间设置。
在本实施例中,第二加热段1392的径向长度比第一加热段1391的径向长度长。
具体地,通过将第二加热段1392的径向长度设置的比第一加热段1391的径向长度长,可充分加热空气形成充足的热气流,以提升对导热通道209的烟支加热效果。在其他实施例中,通过将第一加热段1391的径向长度适当延长,也有利于增大加热不燃烧烟具的加热空间,扩大加热接触面而增强加热效果,从而有效地提升热效率。
在本实施例中,第二加热段1392和第一加热段1391可为一体设置,也可不为一体设置,具体地,一体设置指同一材质一体加工成型或两个结构固定连接成一体,通过第二加热段1392和第一加热段1391设置为一体设置,可节省两者的制造成本。在其他实施例中,当第二加热段1392和第一加热段1391不为一体设置时,则能够分别针对第二加热段1392和第一加热段1391分别做出差别改进的设置。
本发明提供的加热不燃烧烟具通过将第八发热体139分为置于热气形成腔304的第二加热段1392和置于导热通道209的第一加热段1391,并用导气层14作为分隔导热通道209和热气形成腔304,第八发热体139通电后,第八发热体139的第二加热段1392对进入热气形成腔304的气流加热形成热气流后,热气流穿过导气层14进入导热通道209对放入导热通道209内的烟支加热,同时,第八发热体139的第一加热段1391吸收热气流的热量而减少热气流热量损失,并对导热通道209内的烟支进行接触传导式的加热,通过空气加热和周向加热的双向加热,在实现均匀加热的同时降低了空气加热导致的能耗损失,充分利用了第八发热体139通电加热产生的热量,有效提高了热量利用率。
