Description

一种加热元件以及设有该加热元件的电子烟具 技术领域
本发明涉及低温不燃烧电子烟具的技术领域，特别涉及加热元件以及设有该加热元件的电子烟具。
背景技术
低温不燃烧烟草制品中烟具内置有加热元件，通过加热元件对烟草制品进行外部加热实现发烟，加热温度为300-380℃。低温不燃烧烟草产品多为烟草薄片卷制而成，结构紧密，为使加热更加充分，使用刺入型加热元件深入烟草产品中进行接触式热传递。
现有烟具中的刺入型加热元件多为片状或针状。片状加热元件是在金属片两面印刷有发热电阻丝，其存在的问题在于：电阻丝发热效果受金属片与烟草产品接触面限制，并且，片状加热元件不易刺入烟草产品或刺入后无法沿中心线深入，易于发生偏移的现象。针状加热元件虽然尖端更锐利，刺入效果相对较好，但是，其存在的问题在于：由于只能可利用侧壁导热，但是侧壁导热面积有限，因此，发热效果相对较差。
综上，现有烟具中的片状和针状加热元件存在加热接触面有限，烟草产品的局部或边缘部分无法受热，烟草利用率低，加热元件结构不够稳定，易发生折损等问题。
发明内容
为了解决以上现有技术中存在的问题，本发明提供了一种低温不燃烧领域使 用的加热元件以及设有该加热元件的电子烟具。该加热元件能够提高电子烟具对烟草的加热效率和效果，提高加热元件的用的稳定性、可靠性和便利性。
根据本发明的一个方面，提供了一种加热元件，其由主体部以及位于主体部一端的尖端部构成，所述尖端部呈锥状；主体部由多个侧面构成以使其横截面呈多棱状，并且，主体部设有电阻加热部，该电阻加热部例如可以采用发热电阻基片或发热电阻丝，其设置方式可采用接片式、插片式、内芯式或铸件式。
优选的是，构成主体部的侧面为内凹弧形面；此处需指出的是，内凹弧形面有利于主体部的侧面增大侧面面积，从而增大加热元件与烟草制品的接触面积，即增大传热面积，另外，与其他表面形状相比，弧形面有助于增加表面光滑性，从而有助于减小刺入时的摩擦阻力小，并有助于避免烟草粉末挂壁，便于清洁维护。更为优选的是，主体部由三个侧面构成以使其横截面呈三叉形；此处需指出的是，主体部特别采用了三叉形，作为最稳固的几何形状，三叉形有利于在保证加热元件顺利刺入烟草制品的同时，沿其轴线中心方向且不变形。
优选的是，主体部还设有温控部，以便对电阻加热部实施适宜的温度控制。
优选的是，加热元件中的主体部与尖端部为一体不可拆分式结构。采用这种结构，有利于简化加热元件的制造。
优选的是，主体部与尖端部为可拆卸式分体结构。更为优选的是，主体部与尖端部采用螺纹连接、卡扣连接或磁力连接彼此相连。
优选的是，电阻加热部以封釉方式设置在主体部的外表面，与现有技术的设置方式相比，封釉方式有助于实现加热元件外表面的光滑性，从而能够进一步减小刺入时的摩擦阻力小，并进一步避免烟草粉末挂壁。
优选的是，主体部为空心结构，尖端部为实心结构。
优选的是，主体部的电阻加热部在主体部的内部或侧面，温控部位于主体部的内部中心处，例如，主温控部可以设置在主体部的内部轴心处，并连接电池和温控芯片。
优选的是，主体部的电阻加热部采用位于侧面上的发热电阻丝并以串联方式连接，相邻侧面之间焊接有导电部，导电部分别连接相邻侧面上的发热电阻丝的一端。
优选的是，主体部的电阻加热部采用位于侧面上的发热电阻丝并以并联方式连接，即各个侧面上的发热电阻丝分别与电池相连。
优选的是，发热电阻丝绕设在主体部的相应侧面上并且发热电阻丝的绕设部相互之间留有一定距离离。
优选的是，主体部由开设有卡槽的基体部和内设有电阻加热部的尖端锋利的插片部构成，插片部卡合固定在基体部的卡槽内。该结构能够实现插片的快速更换，以便于维修、调节和清洁。
根据本发明的另一个方面，提供了一种电子烟具，其设有上面所述的加热元件。
由于采用上述结构，本发明具有如下优点：
1、根据本发明的加热元件，锥状尖端结构与主体部以横截面多棱状的由多侧面构成的结构相结合，在增大尖端的刺入力的同时，有助于随着尖端的刺入进一步实现烟草产品的松动以及对其的传热。
2、横截面呈三叉状的三侧面主体部有利于电阻加热部沿主体部的布置，三叉形非常牢固，能保持刺入后不变形且始终沿轴心刺入；并且，因三叉形侧壁面积大，提高加热烟草的效率和效果。
3、加热元件中的主体部与尖端部采用一体不可拆分式结构，无连接点无空隙，有利于提高加热元件的整体强度并简化加热元件的加工制造。
4、加热元件中的主体部与尖端部例如通过螺纹连接、卡扣连接或磁力连接等方式，采用可拆卸式分体结构，其突出的优点在于：便于加热元件的更换调整、维护清洁以降低成本、增大适用范围。例如，在主体部或尖端部损坏时，可以借助可拆卸式结构更换损坏部分；或在主体部加热效果不适合或不理想时，可以借助可拆卸式结构换适合的主体部；或者，在需维护清洁加热元件时，可以借助可拆卸式结构拆开主体部和尖端部，以便对加热元件进行更彻底的清洁。另外，主体部还可以由开设有卡槽的基体部和内设有电阻加热部的尖端锋利的插片部构成，插片部卡合固定在基体部的卡槽内，这种结构能够实现插片的快速更换，以便于维修、调节和清洁。
5、由于主体部的侧面在封釉后呈曲面形状，特别是，主体部的侧面为采用了向其轴线内凹的曲面形状，其优点在于：曲面形状增加了加热元件侧壁的面积，增加了发热电阻丝在主体部侧面的排布空间，从而能够确保更快、更均匀地加热烟草，提高烟草产品的利用率；另外，相邻的内凹曲面能够形成更尖利的主体部侧棱，其与尖端部相配合，能够提高加热元件的刺入效果以及刺入烟草后的疏松效果。另外，由于主体部的侧面由三个内凹曲面构成，因此，这种结构更有助于保持加热元件刺入烟草制品的路径与其中心轴线相一致。
6、若尖端部采用实心结构，则能够提高加热元件的整体强度；若主体部和尖端部采用空心结构，则可以节省材料，降低制造成本。
8、若发热电阻基片或发热电阻丝相互之间留有一定距离的方式绕设在主体部的相应侧面上，则能够避免发热电阻丝出现交叉，从而避免加热元件在使用过 程中发生电阻丝过热现象。
9、每个侧面展开图形的顶边为弧形，可增加展开面积，供发热电阻不的面积更大。
10、温控部例如可以采用位于轴心的温控线，以便实时收集温度，防止加热温度过高，更安全。

具体实施方式
具体实施例1：
下面，参照图1-3对本发明的加热元件进行详细说明。
如图1所示，本发明的加热元件由主体部1以及位于该主体部一端的尖端部2构成。尖端部2呈锥状，例如可以采用圆锥状或棱锥状。在加热元件刺入电子 烟具中的烟草制品时，随着尖端部2的逐渐进入，该形状逐渐增大烟草制品的刺入面积，从而能够疏松烟草制品，进而提高热传递效果以及提高加热的均匀性。
与尖端部2相连的主体部1为棒状或杆状，其由三个侧面构成以致其横截面呈三叉状。如图2所示，主体部1的侧面优选为朝主体部的轴线内凹的曲面形状，相比较于平面形状，曲面形状能够增加加热元件侧壁的面积，由此增加了发热电阻丝3在主体部侧面的排布空间，从而能够确保更快、更均匀地加热烟草，提高烟草产品的利用率，并能够减少烟草粉末挂壁的现象发生。另外，由图2可知，相邻的内凹曲面能够形成较为尖利的主体部侧棱，其与尖端部相配合，能够进一步提高加热元件的刺入效果以及刺入烟草制品后的疏松效果。
虽然在附图1-3中所示的加热元件为一体不可拆分式实心结构，但是，作为优选方案，主体部1与尖端部2可采用可拆卸式分体结构，例如，主体部1与尖端部2可采用螺纹连接、卡扣连接或磁力连接方式相互连接。可拆卸式分体结构能够增加加热元件使用的自由度，例如，在主体部1或尖端部2损坏时，使用者通过可拆卸式结构，能够方便地更换损坏部分；在主体部1的加热效果不适合或不理想时，使用者通过可拆卸式结构能够方便地更换适合的主体部1；在需维护清洁加热元件时，使用者可通过可拆卸式结构方便地拆开主体部和尖端部，以便对加热元件进行更彻底的清洁。另外，加热元件还可以采用空心结构，空心结构有利于节省材料而降低成本。
图2-3显示的加热元件为铸件式，一次铸造主体部1且在其侧壁上设有供电阻加热部3放置的凹槽，在中空内部沿轴心设置温控线4(即温控部)。电阻加热部3可采用发热电阻基片，基片的排布方式可为如图一圈，也可多圈，但保持一定距离防止过热。各个侧面上的发热电阻基片、温控线分别直接与电池相连。 具体实施例2：
如图4所示，加热元件为接片式，即：例如，可先制造带电阻加热部3放置凹槽的侧面片，再将三片侧面片组装在一起，形成主体部1，中间为空芯，放置温控线4(即温控部)。
具体实施例3
如图5所示，加热元件为插片式，将三片内芯有电阻加热基片的插片固定在插槽中，此实施例中插槽为三叉形，因此整体表面更光滑曲面，摩擦阻力小。具体实施例4
如图6所示，加热元件为插片式，将三片内芯有电阻加热基片的插片固定在插槽中，此实施例中插槽为圆形，且主体部1的轴心处有温控线(即温控部)，此结构下插片在插槽中更稳定、不易弯折。
具体实施例5
如图7所示，加热元件为内芯式，电阻加热部3在主体部1的内芯。因为主体部1为耐高温的绝缘材料，电阻加热部3为金属材料，两者可以混合且不发生反应，可以将电阻加热部3作为内芯放置在主体1中，该实施例中主体部的内芯电阻加热部呈三叉形排列。
具体实施例6
如图8所示，加热元件为内芯式，电阻加热部3在主体部1的内芯。因为主体部1为耐高温的绝缘材料，电阻加热部3为金属材料，两者可以混合且不发生反应，可以将电阻加热部3作为内芯放置在主体1中，该实施例中主体部的内芯电阻加热部呈圆环形。
具体实施例7
如图9所示，加热元件为内芯式，电阻加热部3在主体部1的内芯。因为主体部1为耐高温的绝缘材料，电阻加热部3为金属材料，两者可以混合且不发生反应，可以将电阻加热部3作为内芯放置在主体1中，该实施例中主体部的内芯电阻加热部呈曲边三角形。
以上内容仅是本发明的最佳实施例。应强调的是，在不脱离本发明思想的前提下，本领域普通技术人员对本发明所作的各种变型和改进均应落入本发明的保护范围内。
