 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。
本发明的加热装置，用于加热不燃烧烟具，对烟草进行加热不燃烧，使其雾化产生烟气，供用户吸入。
如图1-3所示，本发明第一实施例的加热装置，包括第一加热组件10。
第一加热组件10包括第一壳体11、配合在第一壳体11上的第一发热件12、设置在第一发热件12和第一壳体11之间的第一绝缘体13。第一壳体11用于与烟草接触，第一发热体12用于导电发热，第一绝缘体13用于隔绝第一发热件12和第一壳体11，避免两者接触导致短路等问题。第一发热件12通电后发热，热量通过第一绝缘体13传导至第一壳体11，通过第一壳体11对烟草进行加热不燃烧以雾化产生烟气。
本实施例中，第一壳体11为一端封闭、另一端开放的壳体。第一发热件12沿第一壳体11的长度方向穿设在第一壳体11内，第一发热件12的两个引脚121伸出第一壳体11的开放端外，以外接电源。第一绝缘体13填充在第一壳体11内并包覆第一发热件12。
第一壳体11的内表面与第一绝缘体13紧密贴合；第一壳体11的外表面形成与烟草接触的加热表面。第一加热组件10使用时以第一壳体11插进烟草内，加热表面进入烟草内对其进行加热雾化。
为了使第一加热组件10顺畅***烟草内，第一壳体11的封闭端呈锥形，锥形端顶部的尖头更好刺入烟草中。第一壳体11的封闭端上还可以设置通孔，用于通气或注浆等。
第一壳体11采用耐温超过500℃的材料制成，例如金属、陶瓷、石英、云母、玻璃等。
具体地，本实施例中，第一壳体11为扁平状的中空壳体。对应扁平状的第一壳体11，第一发热体12整体呈片状，发热主体可由一长条的金属片沿着第一壳体11的内周弯折形成，金属片的两端对应在第一壳体11的开放端，分别连接两个引脚121。
第一发热体12的发热主体的米电阻（每米电阻值）大于引脚121的米电阻。
第一发热件12采用电阻具有温度曲线的金属材料制成，优选由镍铬合金、铁铬铝合金、不锈钢、镍丝、镍铁合金、铜镍合金、钛和钛合金等中至少一种制成。
第一绝缘体13填充在第一壳体11内且对第一发热件12进行包覆，使得第一发热件12嵌设在第一绝缘体13内，与第一壳体11相绝缘。该第一绝缘体13呈柱体结构，形状对应第一壳体11的内周形状。

进一步地，第一加热组件10还包括设置在第一壳体11的用于与烟草接触的表面上的第一耐高温不粘涂层（未图示）。本实施例中，由于第一壳体11的外表面为与烟草接触的加热表面，因此该第一耐高温不粘涂层设置在第一壳体11的外表面上，确保烟草在第一壳体11上的顺利脱出，防止使用后烟草残渣粘附在其上，保证第一壳体11外表面的清洁。
第一耐高温不粘涂层采用能承受温度在300℃以上高温的材料制成。作为选择，第一耐高温不粘涂层的厚度为0.5μm -500μm。
该第一实施例的加热装置的制造方法，包括第一加热组件10的制造。参考图1-3，第一加热组件10的制造可包括以下步骤：

S1.3、将绝缘浆料注入成型模具内，冷却硬化后形成第一绝缘体13的坯体，与第一壳体11和第一发热件12形成第一加热组件半成品。
其中，在注入绝缘浆料时，主要将绝缘浆料注入第一壳体11内，同时还填充在第一壳体11和第一发热体12之间的间隔。
形成坯体后，坯体填充在第一壳体11内并包覆第一发热件12。
S1.4、将第一加热组件半成品进行高温烧结，坯体固化成型为第一绝缘体13，制得第一加热组件10。
将第一加热组件半成品从成型模具中取出，置入烧结载具中，放置于高温烧结炉内进行高温烧结，使得坯体固化成型为第一绝缘体13，紧密结合在第一壳体11和第一发热体12之间，形成第一加热组件10。

进一步地，本实施例中，第一绝缘体23的端部形成有一绝缘座231。该绝缘座231一体形成在第一绝缘体23上。
第一壳体21的开放端的端面可以抵接在绝缘座231上，第一壳体21的开放端的端面间隔绝缘座231。或者，如图4中所示，第一壳体21的开放端的端部嵌入绝缘座231，从而开放端的端面位于绝缘座231内，使得绝缘座231包覆在第一壳体21的开放端外周，同时也将第一发热件22的引脚221的部分包覆，提高结构稳定性。
第一加热组件20还包括设置在第一壳体21的用于与烟草接触的表面上的第一耐高温不粘涂层（未图示）。该第一耐高温不粘涂层具体设置等可参考上述第一实施例，在此不再赘述。

对应圆筒状的第一壳体41，第一发热体42包括发热筒。该发热筒可由一发热片卷绕形成，发热筒的侧壁上进一步可设有镂空部422。两个引脚421相对连接在发热筒的端部两侧。第一发热体42的米电阻大于引脚421的米电阻。
第一发热件42采用电阻具有温度曲线的金属材料制成，优选由镍铬合金、铁铬铝合金、不锈钢、镍丝、镍铁合金、铜镍合金、钛和钛合金等中至少一种制成。
第一绝缘体43优选由多孔陶瓷材料制成，具有电绝缘且导热性好等性能。制备时由多孔陶瓷材料粉末和粘结剂等先制成绝缘浆料，再通过填注、固化等形成具有一定结构强度的绝缘体。第一绝缘体43的部分填充在第一壳体41和第一发热体42之间的间隔中，对两者进行隔绝。
进一步地，第一加热组件40还包括设置在第一壳体41的用于与烟草接触的表面上的第一耐高温不粘涂层（未图示）。本实施例中，由于第一壳体41的内表面为与烟草接触的加热表面，因此该第一耐高温不粘涂层设置在第一壳体41的内表面上，确保烟草在第一壳体41内的顺利脱出，防止使用后烟草残渣粘附在第一壳体41的内表面上，保证第一壳体41内表面的清洁。
第一耐高温不粘涂层采用能承受温度在300℃以上高温的材料制成。作为选择，第一耐高温不粘涂层的厚度为0.5μm -500μm。
该第四实施例的加热装置的制造方法，包括第一加热组件40的制造。参考图7、8，第一加热组件40的制造可包括以下步骤：
S1.1、制备第一壳体41、第一发热件42和第一绝缘体43的绝缘浆料。
第一壳体41可通过冲压、蚀刻、切割、拉丝、焊接、注塑、烧结等工艺制成。第一发热件42可采用蚀刻、切割、焊接、卷绕等工艺制成。
该步骤S1.1还包括在第一壳体41的内表面涂覆第一耐高温不粘涂层。
S1.2、将第一壳体41和第一发热件42放置于成型模具内并固定。
第一发热件42位于第一壳体41的***。第一发热件42的长度方向平行第一壳体41的长度方向，并且第一发热件42和第一壳体41之间间隔不接触。第一发热件42的两个引脚421位于第一壳体41外。
S1.3、将绝缘浆料注入成型模具内，冷却硬化后形成第一绝缘体43的坯体，与第一壳体41和第一发热件42形成第一加热组件半成品。
其中，在注入绝缘浆料时，主要将绝缘浆料注入第一壳体41和第一发热件42的***，同时还填充在第一壳体41和第一发热体42之间的间隔。
形成坯体后，坯体包覆在第一壳体41和第一发热件42的外周并填充第一壳体41和第一发热件42之间的间隔中。
S1.4、将第一加热组件半成品进行高温烧结，坯体固化成型为第一绝缘体43，制得第一加热组件40。
将第一加热组件半成品从成型模具中取出，置入烧结载具中，放置于高温烧结炉内进行高温烧结，使得坯体固化成型为第一绝缘体43，紧密结合在第一壳体41和第一发热体42之间，形成第一加热组件40。
如图9所示，本发明第五实施例的加热装置，包括第一加热组件50和第二加热组件60。第一加热组件50轴向穿设在第二加热组件60中，第一加热组件50的外周与第二加热组件60的内周之间形成有一环形空间70，用于烟草容置其中。
其中，第一加热组件50包括第一壳体51、穿设在第一壳体51内的第一发热件52、填充在第一壳体51内并包覆第一发热件52的第一绝缘体53。第一壳体51的外表面形成与烟草接触的加热表面。第一加热组件50可为上述第一至第三实施例中的第一加热组件。
第二加热组件60包括两端开放的筒状的第二壳体61、套设在第二壳体61的外周上的第二绝缘体63、嵌设在第二绝缘体63内并位于第二壳体61的***的第二发热件62。第二发热件62的两个引脚621和第一发热件52的两个引脚521均伸出第二绝缘体63外，用于外接电源。
第二发热件62包括发热筒，该发热筒的侧壁上设有镂空部，第二发热件62的具体设置及材料选择等均可参考上述图7所示第四实施例中的第一发热件42。
第二绝缘体63的一端开放并与环形空间70相连通。第二绝缘体63的相对另一端封闭形成封闭端，该封闭端上设有至少一个第二通气孔631。第一加热组件50固定在第二绝缘体63的封闭端上。
第二加热组件60还包括设置在第二壳体61的内表面上的第二耐高温不粘涂层（未图示），可耐300℃以上温度。第二耐高温不粘涂层的厚度为0.5μm -500μm。
可以理解地，第二加热组件60具体可参考上述第四实施例中的第一加热组件。
本实施例相较于上述第一至第四实施例的加热装置，第一加热组件50和第二加热组件60的设置对烟草的加热雾化更加充分，产生烟气更多，满足用户对应需求。
该第五实施例的加热装置的制造方法，包括第一加热组件50的制造以及第二加热组件60的制造。
其中，第一加热组件50可参考上述第一实施例中第一加热组件的制造方法。参考图9，第二加热组件60的制造包括以下步骤：
S2.1、制备第二壳体61、第二发热件62和第二绝缘体63的绝缘浆料；
S2.2、将第二壳体61和第二发热件62放置于成型模具内并固定。
第二发热件62位于第二壳体61的***。
S2.3、将绝缘浆料注入成型模具内，冷却硬化后形成第二绝缘体63的坯体，与第二壳体61和第二发热件62形成第二加热组件半成品。
坯体包覆在第二壳体61和第二发热件62的外周并填充第二壳体61和第二发热件62之间的间隔。
S2.4、将第二加热组件半成品进行高温烧结，坯体固化成型为第二绝缘体63，制得第二加热组件63。
第二加热组件60的制造步骤具体可参考上述第四实施例中第一加热组件的制造方法。
进一步地，该第五实施例的加热装置的制造方法还包括：将第一加热组件50轴向穿设在第二加热组件60中，两者之间形成有环形空间70，用于烟草容置其中。
如图10所示，本发明的加热不燃烧烟具，包括加热装置1，该加热装置1为上述第一至第五实施例中任一实施例的加热装置。
本发明的加热不燃烧烟具还包括外壳2、供电电池3以及烟弹壳4。供电电池3设置在外壳2的一端内，加热装置1设置在外壳2的另一端内，并通过相配合的固定座5和锁紧块6等固定在外壳2内。加热装置1与供电电池3连接，从而供电电池3为加热装置供电。
烟弹壳4配合在外壳2的另一端上，加热装置1位于烟弹壳4内。并且，烟弹壳4上设有开口连通至其内部，烟草7（可制成香烟形式）通过开口***烟弹壳4内并插接至加热装置1上。加热装置1通过供电电池3供电后对烟草进行加热，使其雾化产生烟气。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
