下面结合附图介绍本发明实施例提供的技术方案。
如图1、图2、图3、图4以及图5所示，本发明提供了一种发热装置10，用于将气体加热至所需温度以待烘烤不燃烧烟支30，该发热装置10包括发热体100及支架200这两部分，其中：
发热体100和支架200依次排列，发热体100安装于支架200的一端；在具体设置时，发热体100与支架200之间可以通过粘结剂粘接、焊接等方式固定连接，以使得结构简单；发热体100与支架200之间可以通过凹凸配合、卡扣连接、螺纹连接等方式可拆卸地连接为一体，以便于装拆更换。
支架200开设有第一通槽210，第一通槽210开口于支架200的端面，并且沿着支架200的厚度方向贯穿支架；在具体设置时，由于人在吸烟时，每一口的抽吸量约为30ml以上的气体，时间约为1秒-2秒，根据这个气流量，和吸烟时的吸阻，可以确认第一通槽210直径为0.5
mm -3.0 mm，较佳地，第一通槽210的直径为0.5
mm、1mm、1.5mm、2mm、2.5mm、3mm，当然，第一通槽210的直径并不局限于此，还可以为其他能够满足要求的数值；第一通槽210的形状可以为圆形、矩形或椭圆形的一种，当然，第一通槽210的形状并不局限于此，还可以为其他能够满足要求的形状。
发热体100用于产生热量，并且发热体100上开设有至少一个第二通槽110，第二通槽110开口于发热体100的端面，并且沿着发热体100的厚度方向贯穿沿着发热体100；在具体设置时，第二通槽110的数目可以为一个、两个、三个、四个、五个、六个或是六个以上，当然，第二通槽110的数目并不局限于此；发热体100可以为电加热块，发热体100还可以为电加热片，当然，发热体100的结构形式并不局限于此，还可以为其他能够满足要求的结构；相对于现有发热装置10中的气流孔，第二通槽110的截面积较大，相对于现有发热装置10，发热体100的体积较小。
每一第二通槽110均与第一通槽210相连通，并且所有第二通槽110的截面积之和大于第一通槽210远离第二通槽110一端的截面积；在具体设置时，多个第二通槽110并列设置，第一通槽210位于多个第二通槽110的一侧，并且气体在内外压差的作用下，从第一通槽210流出后分别流入到多个第二通槽110中。
在上述发热装置10中，气体通过第一通槽210进入支架200，并继续经过多个第二通槽110分散进入到发热体100内，经过发热体100的加热形成热气流。根据流体力学公式Q=S*V，其中，Q为流体的流量，S为管路的截面积，V为流速，由于所有第二通槽110的截面积之和大于第一通槽210远离第二通槽110一端的截面积，使得气体从第一通槽210进入第二通槽110后的流速减小，进而使得在无需增加发热装置10长度的情况下气体经过第二通槽110内的时间较长，发热装置10的结构小巧，热损失较少，并且通过发热体100上设置第二通槽110，相对于现有开设小孔的情况，第二通槽110的设置较为简单方便，同时空气在流经发热体100的热交换面积较大，以能够较为可靠地保证气流的加热温度。
为了便于第二通槽110的设置，一种优选实施方式，如图1、图3以及图4所示，所有第二通槽110的截面积相同，以采用同一治具加工所有的第二通槽110，或是采用相同的方式形成第二通槽110，较为方便地在发热体100上形成第二通槽110；当然，第二通槽110的截面积并不局限于此，还可以所有的第二通槽110的截面积均不相同，以适用于特殊的应用场景，也可以一部分第二通槽110的截面积相同，另一部分第二通槽110的截面积不同，以适用于不同的应用场景，第二通槽110的开口形状可以相同，也可以不相同，第二通槽110的开口形状可以为规则形状，第二通槽110的开口形状也可以为不规则形状。
为了便于第二通槽110的设置，一种优选实施方式，所有第二通槽110的开口形状相同，以采用相同形状的治具加工所有的第二通槽110，或是采用同一类型的方式形成第二通槽110，较为方便地在发热体100上形成第二通槽110，当然，第二通槽110的开口形状并不局限于此，还可以所有的第二通槽110的开口形状均不相同，以适用于特殊的应用场景，也可以一部分第二通槽110的开口形状相同，另一部分第二通槽110的开口形状不同，以适用于不同的应用场景。第二通槽110的开口形状为圆形、矩形、椭圆形的一种，以便于气体的流动和第二通槽110的加工制备，当然，第二通槽110的形状并不局限于此，还可以为其他能够满足要求的形状，例如，第二通槽110的形状还可以为扇形、三角形等。
第二通槽110的布置方式具有多种，一种优选实施方式，如图1、图3以及图4所示，所有的第二通槽110呈内外两层环状分布，在具体设置时，所有的第二通槽110分为两部分，第一部分的第二通槽110位于靠近发热体100的中心设置，并且呈环状排布，第二部分的第二通槽110靠近发热体100的边缘设置，并且呈环状排布，第二部分的第二通槽110环绕第一部分的第二通槽110设置，例如，在第二通槽110的数目为18个时，第一部分具有6个第二通槽110，并且设置在内侧，第二部分具有12个通槽，并且设置在外侧；当然，第二通槽110的设置方式并不局限于此，还可以为其他能够满足要求的方式，例如，所有的第二通槽110呈直线分布，或者，所有的第二通槽110阵列分布，或者，所有的第二通槽110呈一层或多层分布。
支架200的结构形式具有多种，一种优选实施方式，如图1、图2、图3以及图4所示，支架200为两端开口的阶梯状腔体结构，支架200包括第一壳体220以及第二壳体230，在具体设置时，第一壳体220和第二壳体230可以为分体式结构，独立成型后通过焊接、粘结剂粘接等方式固定为一体，第一壳体220和第二壳体230还可以通过铸造、注塑等工艺一体成型。其中：
第一壳体220为T型结构，第一壳体220的内部形成有第一通孔211，第一通孔211的截面积小于所有第二通槽110的截面积之和；在具体设置时，第一壳体220包括第一柱体221以及第一板体222，第一柱体221以及第一板体222连接为一体，第一通孔211开口于第一柱体221，并且第一通孔211贯穿第一柱体221和第一板体222。
第二壳体230设置在第一壳体220的横线端，第二壳体230的内部形成有第二通孔212，第二通孔212与第一通孔211相连通，并且第二通孔212开口面积大于第一通孔211；在具体设置时，第二壳体230设置在第一板体222背离第一柱体221的一侧，第二通孔212和第一通孔211形成阶梯状的第一通槽210，以便于气流的通过。
第二壳体230与发热体100通过连接管300相连接，并且发热体100和连接管300相对第二壳体230能够拆卸；在具体设置，第二壳体230和发热体100之间可以直接相连接，例如，发热体100壳第二壳体230之间通过螺纹连接、卡扣连接、凹凸配合等方式安装在一起，第二壳体230和发热体100之间还可以简介相连，例如，第二壳体230和发热体100分别与连接管300相连接。
上述发热装置10中，气流经过第一通孔211进入支架200，并经过第二通孔212扩散，然后分散进入到多个第二通槽110中，以较为方便快捷地实现气流的流入。通过限定第二壳体230与发热体100通过连接管300可拆卸连接，以便于发热装置10的安装和拆卸。当然，支架200的结构形式以及支架200与发热体100之间的连接方式并不局限于此，还可以为其他能够满足要求的形式。
为了便于发热体100和支架200之间的安装，具体地，如图3以及图4所示，发热体100嵌设在连接管300内，连接管300套设在第二壳体230的外侧，并且连接管300与第二壳体230的外壁固定连接，在具体设置时，连接管300与第二壳体230的外壁之间螺纹连接，连接管300的一端内部设置有内螺纹，第二壳体230一端的外壁上形成与内螺纹相配合的外螺纹，二者锁附在一起，当然，连接管300与第二壳体230外壁的固定连接方式并不局限于此，还可以为其他能够满足要求的方式。上述发热装置10在组装时，首先将发热体100插入连接管300，并通过外力将发热体100嵌设在连接管300的一端内，然后将连接管300的另一端与第二壳体230之间固定在一起。在具体设置时，发热体100和连接管300之间的安装方式、连接管300与第二壳体230之间的连接方式并不局限于此，还可以为其他能够满足要求的方式。
为了便于气流的分散，具体地，如图3以及图4所示，所有的第二通槽110在支架200上的投影均落入第一通孔211内，并且所有的第二通槽110在支架200上的投影位于第二通孔212的外侧，以避免第二通槽110和第二通孔212直接正对，使得气流在第一通孔211内扩散后在分散到第二通槽110内，保证了气流的分散效果。在具体设置时，第二通槽110相对支架200的位置关系并不局限于此，还可以为其他能够保证分散效果的方式。
为了保证气流的分散效果，具体地，如图1、图3以及图4所示，发热体100与支架200同轴线，并且所有的第二通槽110关于二者的轴线对称分布，以使得气流经过第二通槽110后均匀分散，使得低温不燃烧烟支30能够得到均匀的烘烤。在具体设置时，第二通槽110的布置并不局限于此，还可以为其他能够满足要求的方式，例如，发热体100与支架200也可以呈任意角度设置，再例如，所有的第二通槽110关于发热体100与支架200的轴线中心对称分布。
另外，如图5以及图6所示，本发明还提供了一种低温不燃烧烟具01，该低温不燃烧烟具01包括外管20，还包括如上述任一项技术方案的发热装置10，发热装置10安装在外管20的一侧，发热装置10和外管20相连通，在具体设置时，发热装置10安装在外管20的一侧，不燃烧烟支30安装在外管20的另一侧，并且外管20的这两侧相连通，使得发热装置10和不燃烧烟支30相连通。
在上述低温不燃烧烟具01中，由于发热装置10内，气体通过第一通槽210进入支架200，并继续经过多个第二通槽110分散进入到发热体100内，经过发热体100的加热形成热气流。根据流体力学公式Q=S*V，其中，Q为流体的流量，S为管路的截面积，V为流速，由于所有第二通槽110的截面积之和大于第一通槽210远离第二通槽110一端的截面积，使得气体从第一通槽210进入第二通槽110后的流速减小，进而使得在无需增加发热装置10长度的情况下气体经过第二通槽110内的时间较长，发热装置10的结构小巧，热损失较少，并且通过发热体100上设置第二通槽110，相对于现有开设小孔的情况，第二通槽110的设置较为简单方便，同时空气在流经发热体100的热交换面积较大，以能够较为可靠地保证气流的加热温度。因此，具有该发热装置10的低温不燃烧烟具01中，经过发热装置10的气流温度达到设定值，并且能够较为稳定地烘烤不燃烧烟支30，并且低温不燃烧烟具01的结构小巧。
外管20的结构形式具有多种，如图5以及图6所示，一种优选实施方式，外管20内壁上形成有环状凸台21，环状凸台21与外管20可以为一体式结构，通过注塑、铸造工艺一体成型，环状凸台21和外管20可以为分体式结构，通过焊接、粘接等工艺连接为一体。发热装置10设置在环状凸台21的一侧，不燃烧烟支30设置在环状凸台21的另一侧，环状凸台21内部的空间连通发热装置10和不燃烧烟支30，保证了经过发热体100加热后的分散气体流向不燃烧烟支30。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述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。
