具体实施方式
本发明的核心是提供了一种内燃式野营柴火炉，能够使火头罩内的火焰集中，使火焰进行有效加热。
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造 性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参考图1-图11，本发明实施例提供了一种内燃式野营柴火炉，包括外筒7、隔热筒1和燃烧筒2；其中，外筒7的上部筒壁上开设有若干第一进风孔701，用于外部空气进入，第一进风孔701沿圆周方向均匀布置在外筒7的筒壁上，可以设置多圈，外筒7可采用钣金制成；隔热筒1位于外筒7的内部，隔热筒1的高度与外筒7的高度基本相同，隔热筒1与外筒7之间存在间隙，隔热筒1的上部筒壁上开设有第二进风孔101，其位置与第一进风孔701的位置对应，也可以沿隔热筒的圆周设置多圈；燃烧筒2位于隔热筒1的内部，燃烧筒2的顶部位于第二进风孔101的下方且与隔热筒1的内壁面密封连接，通过燃烧筒2的顶部将隔热筒1的上部和下部隔离开，下部为隔热筒1与燃烧筒2之间形成环形的隔热腔室9；外筒7的上部和隔热筒1的上部形成双层火头罩，火焰从燃烧筒2的炉膛口出来，进入隔热筒1的上部区域，即进入双层火头罩内。被加热容器可放置在双层火头罩上。本发明中的内燃式野营柴火炉将火头罩与炉体设置成一体结构，且采用双层结构，与现有技术中的火头罩相比，火焰在双层火头罩内，既可以通过外筒7的第一进风孔701和隔热筒1的第二进风孔101向火头罩内通入空气，使燃料燃烧充分，同时，通过双层防风保温的结构，减小外部空气对火头罩内部的火焰进行扰动，从而使火焰更加集中，能够对被加热容器进行更有效地加热。
上述内燃式野营柴火炉主要以可再生生物质燃料为燃烧原料，任何可以燃烧的燃料都可以使用，如树枝、树叶、枯草、树皮、树根、坚果壳、灌木、牛粪、秸秆、废纸板等，特别适合野营使用，取材方便。使用时，将燃料从火头罩上方放入燃烧筒内，从燃烧炉的炉口上方点火，燃烧方式为自上而下燃烧。经测试得到，燃烧温度高达1000°以上，180克木材或者生物颗粒可以持续燃烧15分钟左右，足够做好一餐饭。该内燃式野营柴火炉不仅可以供家庭单独使用，又可以作为户外野营使用。如图1和图4所示，在本实施例中，燃烧筒2包括筒体203、锥接件202、顶盖201和封底；其中，筒体203的筒壁上开设有若干第三进风孔2031，第三进风孔2031沿筒体203的圆周方向均布，且优选地靠近筒体203下部设置，目的是为了使筒体203的下部能够进入空气， 为底部燃料进行供氧，使燃烧更充分；锥接件202为上下具有开口的圆锥筒状结构，锥接件202上开设有若干第四进风孔2021，优选为两圈，且锥接件202的较大的端口与筒体203的上端连接，锥接件202的较小的端口与顶盖201的下端口连接；在锥接件202上设置第四进风孔2021的作用是为了使燃烧筒2内位于上部的燃料进行混氧燃烧，即空气从第四进风孔2021进入到燃烧筒2内，此处的燃料由于高温干馏气化作用，产生可燃烟气，为了提高燃烧效率，将可燃烟气与空气充分接触，进行混氧燃烧，一方面提高了燃烧效率，另一方面减少了烟雾；顶盖201具有下沉式弧形凹面，中间开设有炉膛口，设置下沉式弧形面是为了方便燃料顺利地滑入燃烧炉2内部。顶盖201的上端口边缘与隔热筒1的筒壁密封连接，则隔热腔室9中的空气不能进入双层火头罩内，只能进入燃烧筒2，这样是为了保证进入燃烧筒2内的空气充足，燃烧充分；封底密封连接在筒体203的下端，燃料放置在封底上。
当采用上述燃烧筒2时，内燃式野营柴火炉的工作原理是：空气从内燃式野营柴火炉的底盖5的底部通风口501进入隔热筒1和燃烧筒2之间形成的隔热腔室9内，空气只能通过燃烧筒2的第三进风孔2031和第四进风孔2021进入燃烧筒2内，燃料在燃烧筒2内进行直接燃烧和混氧燃烧。由于隔热腔室9围绕在燃烧筒2外侧，则隔热腔室9内的空气被加热，从而使外部的冷空气在进入燃烧筒2之前进行预热，从而使燃烧迅速高效。并且隔热筒1具有保温的作用，燃烧筒2的热量被隔热腔室9的气体阻隔，减小了热量向外扩散。
当然，燃烧筒2还可以采用筒径一致的一体结构，只要能够放置燃料并充分燃烧即可。
为了进一步提高燃烧效率，如图1和图6所示，内燃式野营柴火炉还包括设置在隔热筒1内且位于燃烧筒2下方的鼓风组件4，通过鼓风组件4向隔热筒1内鼓风，进而增大进入燃烧筒2内空气的压力，增大空气通量，供氧更加充足，燃烧更加充分。当然，也可以不设置鼓风组件4，而是通过空气自行进入燃烧筒2内。设置鼓风组件4是更优选的方案。
作为优化，如图6所示，在本实施例中，鼓风组件4包括风扇支架401和风扇；风扇支架401为环形结构，风扇固定在风扇支架401的中心孔内，风 扇支架401的边缘设置有多个支撑筋，风扇支架401通过支撑筋固定在内燃式野营柴火炉的底盖5上，为了增大进入隔热腔室9内的空气流速，将风扇支架401的中心孔设置成由炉底向炉顶逐渐缩口的圆锥孔。风扇可采用直流风扇。当然，鼓风组件4除了采用上述结构外，还可以是鼓风机，将鼓风机固定在隔热筒1上即可。只要能向燃烧筒2内供风，其它具有鼓风功能的设备同样可以使用。
更进一步地，如图1和图5所示，在本实施例中，内燃式野营柴火炉还包括导流件3，导流件3设置在隔热筒1内部、且位于燃烧筒2和鼓风组件4之间，用于将从鼓风组件4中出来的空气导流至隔热筒1和燃烧筒2之间的隔热腔室9中。这样可以使鼓风组件4中的空气更加快速顺畅地进入隔热腔室9内，进而快速进入燃烧筒2内，减少空气流通阻力，减少空气压力损失，保证进入燃烧筒2内的空气充足，更进一步地提高燃烧效率。当然，导流件3只是优选方案，也可以不设置导流件3。
作为优化，如图5所示，本实施例提供了一种具体的导流件3，导流件3包括锥形板301和固定板302，锥形板301最大直径小于隔热筒1的直径，与燃烧筒2的直径相当，固定板302沿锥形板301的径向方向向外延伸，通过固定板302将锥形板301固定在隔热筒1内壁上，锥形板301的边缘与隔热筒1之间存在用于进风的间隙，锥形板301的尖端相对于其边缘更加靠近鼓风组件4。则从鼓风组件4出来的风经过导流件3的锥形板301的导流作用，直接进入隔热腔室9内，进而通过第三进风孔2031和第四进风孔2021进入燃烧筒2内。当然，导流件3还可以由具有弧形面的弧形板和固定件组成，只要能够起到导流空气至隔热腔室9的作用即可。
如图1、图7和图8所示，内燃式野营柴火炉还包括设置在外筒7上端的若干翻转支撑架8。翻转支撑架8在使用时向外筒7外侧翻转，用于支撑被加热容器。由于被加热容器的底部面积可能会很大，只通过外筒7的上端边缘来支撑被加热容器，会出现支撑不稳的情况。因此，通过翻转支撑架8来增大对被加热容器的支撑半径，保证支撑稳固。在不使用时，将翻转支撑架8向外筒7的中心翻转，使翻转支撑架8收起，减小内燃式野营柴火炉的占用空间。翻 转支撑架8的数量根据实际需要设置，只要能够稳固地支撑容器即可，在此并不做限定。当然，内燃式野营柴火炉也可以不设置翻转支撑架8，只通过外筒7边缘来支撑被加热容器，或者采用不可翻转的固定支撑架，翻转支撑架8是优选的方案。
进一步地，如图7和图8所示，翻转支撑架8包括支撑臂801和支爪802；其中，支撑臂801固定在外筒7的上部筒壁上，具有铰接孔；支爪802的一端也开设有铰接孔，通过铰接孔与支撑臂801铰接，且支爪802的承载面具有用于防滑的波纹齿结构，当支爪802向外翻转并定位后，支爪802的承载面与水平面之间的夹角优选为为0°～15°，当然并不局限于此数值范围。
如图1、图9和图10所示，内燃式野营柴火炉还包括设置在内燃式野营柴火炉的底盖5上的若干翻转脚支架6，数量在此不做具体限定，翻转脚支架6包括安装座601和脚架602；安装座601固定在底盖5上，脚架602铰接在安装座601上。使用时，脚架602沿底盖5的径向方向向外翻转，脚架602与底盖5的夹角大于定于90°，通过翻转脚支架6将内燃式野营柴火炉支撑起来一定高度，这样，空气可以更顺畅地从内燃式野营柴火炉的底盖5进入隔热筒1内。当不使用时，将脚架602向底盖5的中心翻转，将脚架602收起，减小内燃式野营柴火炉的占用空间。当然，也可以采用不可翻转的固定脚支架或者不设置脚支架。
如图1-图3所示，在本实施例中，外筒7的位于燃烧筒2上方的筒壁上还开设有填料口703，隔热筒1的位于燃烧筒2上方的筒壁上还开设有与填料口703位置对应的进料口102，即在双层火头罩侧壁上开设有填料用的进口。设置填料口703和进料口102的目的是为了在容器正在被加热的过程中，直接通过火头罩侧壁上的填料口703和进料口102向燃烧筒2中添加燃料，不需要将被加热容器从火头罩上拿起，保持持续加热，填料更方便。当然，也可以不设置填料口703和进料口102，而是在火头罩的上方进行填料。
如图1和图2所示，在本实施例中，外筒7的筒壁上还设置有散热孔702，散热孔702位于第一进风孔701的下方，用于将传递到外筒7上的热量快速地向外散发。散热孔702的位置和数量在此不做限定。
本发明实施例提供了一种具体的内燃式野营柴火炉，其中，外筒7为圆筒结构，半径为54mm，其上的散热孔702直径为3mm。燃烧炉2的直径为82mm，高度为175mm，炉膛口的直径为60mm，锥接件202上的第四进风孔2021的数量为两圈，每圈18个，直径为3mm；筒体203上的第三进风孔2031距离封底30mm，数量为8个，直径也为3mm。外筒7与隔热筒1之间的间距为6mm，隔热筒1与燃烧筒2之间的间距为5mm；隔热筒1上部设五圈第二进风孔102，每圈32个，直径为3mm。当然，这些只是本实施例的一种具体结构，根据实际使用需求，可以改变各部分的尺寸，在此不做具体限定。
本说明书中各个实施例采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似部分互相参见即可。
对所公开的实施例的上述说明，使本领域专业技术人员能够实现或使用本发明。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的，本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下，在其它实施例中实现。因此，本发明将不会被限制于本文所示的这些实施例，而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
