 本发明的实施方式
为了对本发明的技术特征、目的和效果有更加清楚的理解，现对照附图详细说明本发明的具体实施方式。
如图1-3所示，本发明一些实施例中的低温烘烤烟具可包括壳体1、加热组件2、滑动烟管3、导向筒4、滑动套5、以及弹性件6。壳体1上开设有可供烟支7穿过的插烟口111，滑动烟管3可滑动安装于壳体1内，滑动烟管3的轴向一端对应于插烟口111设有用于供烟支7插入的第一插口31，另一端形成有用于供加热组件2插入的第二插口321。烟支7可经由插烟口111、第一插口31插入到滑动烟管3中，加热组件2的一端可穿过第二插口321伸入到滑动烟管3中并插入到烟支7中，对烟支7进行烘烤加热。
壳体1在一些实施例中可包括下壳12以及盖设于下壳12上端的上壳11，上壳11包括一顶壁112，插烟口111开设于顶壁112上。上壳11、下壳12在本实施例中均大致呈长方体状，上壳11的底端开口并可拆卸地盖设于下壳12上。
导向筒4固定安装于壳体1中，导向筒4大致呈两端敞开的圆筒状，其形成用于容置滑动烟管3和滑动套5的容腔45。在一些实施例中，导向筒4可通过焊接、螺接、卡接等方式固定安装于上壳11中，其顶部可抵靠于上壳11的顶壁112上。在另一些实施例中，导向筒4也可与上壳11一体成型，其可由上壳11的顶壁112向下延伸形成。
结合图2-5所示，加热组件2安装于壳体1内，其包括用于插接于烟支7内的插接部211。加热组件2在一些实施例中可包括加热元件21以及用于安装加热元件21的基座22。加热元件21与第一插口31相对的一端形成插接部211。加热元件21由电源供电后，可对插入到滑动烟管3中的烟支7进行烘烤加热。加热元件21可以为片状或棒状，加热元件21与第一插口31相对的端部形成有尖头导向结构，便于插入到烟支7中进行加热。
基座22的外形可呈长方体状、圆柱状等形状，加热元件21的底部（背离第一插口31的一端）可插装于基座22内。加热组件2在一些实施例中还可包括安装于基座22中与加热元件21电性连接的电路板23。基座22的底部形成有用于安装电路板23的安装槽224，安装槽224的一侧敞开，便于电路板23插装入安装槽224中。基座22内形成有沿其纵向延伸的隔离部223，隔离部223将基座22的内腔分隔成第一隔离腔221、第二隔离腔222，加热元件21的正、负极引线可分别经由第一隔离腔221、第二隔离腔222连接至电路板23上，将正、负极引线相隔离，降低短路的风险。
基座22在一些实施例中可包括分别位于加热元件21两相对侧的第一半座225、第二半座226，第一半座225、第二半座226合围后形成基座22。在本实施例中，第一半座225、第二半座226分别位于加热元件21厚度方向的两相对侧。在其他实施例中，第一半座225、第二半座226也可分别位于加热元件21宽度方向的两相对侧。
第一半座225、第二半座226彼此相对的内侧面上分别形成有相互插接的第一插接部2251、第二插接部2261，第一插接部2251、第二插接部2261相互插接后形成隔离部223，且第一插接部2251、第二插接部2261插接后将加热元件21夹持固定于第一插接部2251、第二插接部2261之间。第一半座225、第二半座226的底部分别形成有第一插槽2253、第二插槽2263，第一插槽2253、第二插槽2263共同形成用于安装电路板23的安装槽224。
该加热组件2在组装时，将第一插接部2251、第二插接部2261分别从加热元件21的两相对侧相互插接，并将电路板23分别插入第一插槽2253、第二插槽2263中即可完成组装，第一插接部2251、第二插接部2261插接后将第一半座225、第二半座226相互插接固定，同时将加热元件21夹持固定于第一插接部2251、第二插接部2261之间，结构简单，组装方便。
进一步地，基座22在一些实施例中还可包括盖设于基座22顶部的端盖25、以及套设于基座22和端盖25外的外套24。基座22可包括朝向插烟口111一侧的座体227和远离插烟口111一侧的底座228，其中，座体227的外形尺寸小于底座228的外形尺寸，外套24可套设于座体227外并座设于底座228上。在一些实施例中，外套24的外形尺寸可与底座228的外形尺寸相当，以提高美观性。
基座22与外套24之间可通过卡接、螺接等方式相互固定。在本实施例中，座体227上向外凸出形成有第一卡扣2252、第二卡扣2262，该第一卡扣2252、第二卡扣2262分别形成于第一半座225、第二半座226上。外套24上分别对应第一卡扣2252、第二卡扣2262形成有第一卡槽241、第二卡槽242，第一卡扣2252、第二卡扣2262分别与第一卡槽241、第二卡槽242相互卡扣后，将第一半座225、第二半座226分别卡扣固定于外套24上。
进一步地，下壳12内还可设置有用于安装加热组件2的固定部121，固定部121的顶部敞开，供加热组件2装入。固定部121可由下壳12内部一体延伸形成，或者固定部121也可以独立设置。
滑动烟管3大致呈管状，其形成用于收容烟支7的插孔36。插孔36的顶部敞开形成有供烟支7插入的第一插口31，插孔36底部形成有底壁32，底壁32上开设有供加热元件21插入的与插孔36连通的第二插口321。在一些实施例中，第二插口321的形状与加热元件21的横截面的形状相对应，例如，可以为矩形，以使加热元件21与烟支7分离时，底壁32可通过摩擦作用刮去加热元件21上的残余物质，对加热元件21进行清洁。
滑动烟管3可滑动安装于容腔45中且与容腔45同轴设置，通过按压烟支7，可使滑动烟管3相对于容腔45在远离加热组件2的分离位置和靠近加热组件2的工作位置之间来回移动，实现烟支7与加热元件21相插接或分离，操作方便。当滑动烟管3位于工作位置时，加热元件21的插接部211完全伸入到插孔36中，如图2所示；当滑动烟管3位于分离位置时，插接部211至少部分地从插孔36移出，如图3所示。滑动烟管3的滑动方向与烟支7的轴向平行，在滑动烟管3滑动的过程中，不会造成烟支7的折断。在本实施方式中，当滑动烟管3位于分离位置时，插接部211一部分伸入于插孔36内，另一部分位于插孔36外，即插接部211始终至少部分位于插孔36内。在其他实施例中，当滑动烟管3位于分离位置时，插接部211也可以全部位于插孔36外。
在一些实施例中，当滑动烟管3处于分离位置时，滑动烟管3的顶部可抵靠于上壳11的顶壁112上，方便定位，且距离插烟口111的位置最近，利于对烟支7进行插拔操作。
滑动套5可移动及可转动地安装于容腔45中且与容腔45同轴设置。滑动套5套设于滑动烟管3外，滑动套5与滑动烟管3之间形成有按压转动结构，以使滑动套5对应于每次按压动作可向固定方向转动规定角度，例如30度。滑动套5与滑动烟管3之间还形成有活动连接结构，以使滑动套5与滑动烟管3保持活动连接状态，防止当滑动烟管3处于工作位置时，滑动烟管3可自由的向插烟口111的方向移动。
弹性件6与滑动套5连接，向滑动套5远离第一插口31的一侧提供弹性力， 从而将滑动烟管3弹性保持在分离位置或工作位置。弹性件6在一些实施例中可以为弹簧，该弹簧可套设于滑动烟管3外，且弹簧的一端与滑动套5的底部相抵，另一端与下壳12的顶壁相抵。在其他实施例中，该弹簧也可以与外套24、固定部121等其他元件相抵。
结合图6-8所示，容腔45的内壁面形成有可供滑动套5滑移的多个第一滑槽421以及可供滑动套5抵靠的多个止动部41。该第一滑槽421沿平行于容腔45的轴向方向延伸，且该多个第一滑槽421与该多个止动部41沿容腔45的周向交替分布。每一止动部41均可包括沿纵向延伸的纵侧面413以及由该纵侧面413的纵向两端分别向两侧延伸的第一倾斜面411、第二倾斜面412。当滑动烟管3由分离位置向下滑动至工作位置时，滑动套5与第一倾斜面411相抵，纵侧面413用于卡止滑动套5，防止其继续向固定方向转动，从而将滑动烟管3弹性保持在工作位置。
具体地，导向筒4的内壁面凸出形成有沿其轴向延伸的至少三组延伸部43，且该至少三组延伸部43沿容腔45的周向均匀间隔分布，每相邻两组延伸部43之间形成第一滑槽421，延伸部43的底部形成止动部41。
在一些实施例中，导向筒4的顶端周圈向内延伸形成有凸缘44，延伸部43可由该凸缘44向下延伸至导向筒4的底端附近。延伸部43的底部形成有第一倾斜面411、第二倾斜面412、以及纵侧面413。第一倾斜面411与第二倾斜面412的倾斜度相同或相近，且第一倾斜面411与第二倾斜面412到导向筒4底面的最小距离相同或大致相同。
在一些实施例中，每组延伸部43均包括沿容腔45的周向依次排布的第一延伸部431、第二延伸部432、第三延伸部433。第一延伸部431、第三延伸部433凸出于容腔45内壁面的高度大致相当，且第一延伸部431、第三延伸部433凸出于容腔45内壁面的高度均大于第二延伸部432凸出于容腔45内壁面的高度，以使第一延伸部431和第三延伸部433之间形成有第二滑槽432。第三延伸部433的底面形成第二倾斜面412，第一延伸部431、第二延伸部432的底面共同形成第一倾斜面411。在其他实施例中，容腔45的内壁面也可不形成有第二滑槽432，即第一延伸部431、第二延伸部432、第三延伸部433凸出于容腔45内壁面的高度也可大致相当。
滑动套5在一些实施例中可包括中空的圆筒状本体53以及由该本体53的外壁面向外凸出形成的至少一个导向块51，该导向块51可在第一滑槽421中上下滑动。在本实施例中，导向块51的数量与第一滑槽421、止动部41的数量相对应。导向块51的顶端可伸出本体53的顶端之外，该导向块51的顶端端面形成第一啮合面511。当滑动烟管3位于工作位置时，第一啮合面511与第一倾斜面411相抵靠，导向块51的侧壁512与纵侧面413相抵靠，以将导向块51卡止固定。在一些实施例中，第一啮合面511的倾斜度可与第一倾斜面411、第二倾斜面412的倾斜度相同或相近，以使滑动套5的运动更平滑。
该按压转动结构可包括该至少一个第一啮合面511以及由滑动烟管3的外壁面形成的与该第一啮合面511相啮合的锯齿牙332，且第一啮合面511的数量少于锯齿牙332的数量。第一啮合面511的倾斜度与锯齿牙332的倾斜度相对应，以使运动更顺滑。
滑动烟管3在一些实施例中可包括朝向插烟口111的第一部33以及背离插烟口111的第二部34，第一部33的内径与第二部34的内径相等，第一部33的外径大于第二部34的外径，以使第一部33的底端外圈形成锯齿牙332。第一部33的外侧壁上还可凸出形成有至少一个滑块331，该至少一个滑块331可滑动安装于第一滑槽421和/或第二滑槽422中，以使滑动烟管3相对于导向筒4只可在轴向相对移动但不能相对转动，避免在运动过程中造成烟支7的折断。
第二部34的外壁面向外凸出形成有至少一个限位凸起341，滑动套5的内壁面周圈向内凹陷形成有与锯齿牙332的形状相对应的限位滑槽52，该至少一个限位凸起341与该限位滑槽5相配合形成活动连接结构。当滑动套5在按压转动结构的作用下转动时，该至少一个限位凸起341可在限位滑槽52内作锯齿状轨迹滑动，使滑动烟管3与滑动套5保持活动连接状态，防止当滑动烟管3处于工作位置时，滑动烟管3自由的向插烟口111的方向移动。
在一些实施例中，滑动套5的内壁面上还可开设有可供该至少一个限位凸起341通过的导槽54，该导槽54由滑动套5朝向插烟口111的一端端面向下延伸至与限位滑槽52相连通，在滑动套5与滑动烟管3插装时，限位凸起341可经由导槽54滑动装配到限位滑槽52中，然后再将滑动套5与滑动烟管3相对转动一定角度将限位凸起341与导槽54周向错开，装配更方便。当滑动烟管3处于工作位置时，导槽54与限位凸起341周向错开，以避免限位凸起341沿导槽54自由的向插烟口111的方向移动。
在本实施例中，滑动烟管3的第二部34的外壁面向外凸出形成有两个限位凸起341，该两个限位凸起341呈半球形且分布于第二部34的两相对侧，利于提高运动时的平滑度以及结合的稳定性。滑动套5的外壁面凸出形成有四个导向块51，导槽54的数量与限位凸起341的数量相对应，即导槽54的数量为两个，且该两个导槽54分别形成于两个相对设置的导向块51上。
在其他实施例中，该活动连接结构也可包括由第二部34的外壁面凹陷形成的与锯齿牙332的形状相对应的限位滑槽、以及由滑动套5的内壁面凸出形成的至少一个限位凸起，该至少一个限位凸起可在该限位滑槽内作锯齿状轨迹滑动，使滑动烟管3与滑动套5保持活动连接状态。相应地，为便于装配，可在滑动烟管3的外壁面上开设可供该限位凸起通过的导槽，该导槽由滑动烟管3背离插烟口111的一端端面向上延伸至与该限位滑槽相连通。
再如图3所示，在烟支7未插入时，滑动烟管3在弹性件6的作用下位于壳体1最靠近插烟口111的位置（分离位置），此时，滑动套5的导向块51处于导向筒4的第一滑槽421中，滑动烟管3与滑动套5之间通过限位凸起341与限位滑槽52保持活动连接状态；在弹性件6的作用下，滑动烟管3的顶端与上壳11的顶壁112相抵，和/或，滑动烟管3上的滑块331的顶端与导向筒4的凸缘44相抵，以使滑动烟管3弹性保持在该分离位置。
如图2所示，将烟支7从插烟口111装入到滑动烟管3内，此时，推动烟支7，滑动烟管3在烟支7的推力作用下，滑动烟管3上的滑块331在对应的第一滑槽421和/或第二滑槽422内滑动，带动滑动套5沿第一滑槽421向下滑动，当导向块51向下滑动至脱出第一滑槽421时，继续推动烟支7，锯齿牙332与第一啮合面511配合，使得滑动套5向固定方向转动并向下滑动挤压弹性件6；松开对烟支7的按压后，滑动套5在弹性件6的作用下向上复位，使得第一啮合面511与第一倾斜面411相抵靠，侧壁512与纵侧面413相抵靠，从而卡止导向块51，将滑动烟管3弹性保持在工作位置。此时，滑动烟管3相对于插烟口111向下滑动了一段距离，使得插接部211完全伸入到插孔36中，此时，可通过加热元件21对插入到滑动烟管3中的烟支7进行烘烤加热。
当烟支7加热完后，再次按压烟支7，推动滑动烟管3、滑动套5向下运动，使得第一啮合面511与第一倾斜面411分离，锯齿牙332与第一啮合面511配合，使得滑动套5向固定方向转动；松开对烟支7的按压后，滑动套5在弹性件6的作用下向上复位，使得导向块51滑动到相邻的第一滑槽421中，并在弹性件6的作用下继续向上复位滑动，直至滑动烟管3重新复位至如图3所示的分离位置。此时，滑动烟管3相对于加热元件21向上滑动了一段距离，使得插接部211至少部分地从插孔36移出，实现烟支7与加热元件21的分离，便于将烟支7拔出，减少或避免烟支7在加热元件21上附着的残余物质。
可以理解地，上述各技术特征可以任意组合使用而不受限制。
以上实施例仅表达了本发明的优选实施方式，其描述较为具体和详细，但并不能因此而理解为对本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，可以对上述技术特点进行自由组合，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，凡跟本发明权利要求范围所做的等同变换与修饰，均应属于本发明权利要求的涵盖范围。
