Description

火盆 技术领域
本发明属于炉具领域，尤其涉及一种取暖火盆技术领域。
 背景技术
地球大多数地区是一年四季，具有冬季，冬季比较寒冷，人们在野外需要烧柴取暖。传统的火盆或者柴火取暖炉应运而生。传统的柴火炉是直筒式的设计，除了开口，只在在底部设有格栅，周圈封闭。这种情况就造成了火星乱窜，燃烧不充分以及灰烬掉落不好处理等现象。为此有技术人员做了很多改进设计。
如专利号为CN202021929296.2的中国专利报道了一种不锈钢野营柴火炉，其包括炉体，炉体内部设有炉腔；炉腔的下端设有格栅；所述格栅是块一体板且往炉腔的开口方向凹陷呈拱形状；所述格栅上设有格栅孔；所述格栅的表面设有第一加强筋。由于格栅是块一体板，在结构上比一根根金属拉丝的结构更加稳固；在形状上做成了拱形，并在表面用加强筋进行加固，比平铺的板在形式上更难塌陷，结构合理，安全性高。其不足之处在于依然存在一些火星乱窜，燃烧不充分现象需要克服。
 技术问题

进一步，所述的进气筒柱主体呈现圆台形，使火盆本体套置固定在进气筒柱的下段上，从而提高气体速度，减少烟尘。
进一步，所述的火盆本体的侧壁圆周均匀地分布有旋风进口，且为纵向延伸的旋风进口，大大提高旋风进气量，强化旋风效果。
进一步，所述的旋风进口布置有导风罩。
再进一步，所述导风罩是利用火盆本体的侧壁冲压成型，与火盆本体做成一体件，便于生产制造。
优选，所述的进气孔是采用纵向延伸的长条孔，便于进风。

 本发明的实施方式
以下结合附图实施例对本发明作进一步详细描述。
如图1～7，一种火盆，其包括有火盆本体5、接灰盘8、外壳3、底盘2、底座1等主要部件，其中，火盆本体5顶部带有环形边51，盖有环形档环57，在其口沿上盖有环形导风板7，底部分布有漏孔52，便于使燃尽的炉灰通过，并且，在火盆本体5的侧壁上沿圆周均匀地分布有纵向延伸的旋风进口53，通常，在旋风进口53布置有导风罩54，使气流能旋转地进入火盆本体5的内腔里，这种导风罩54是利用火盆本体5的侧壁冲压成型，与火盆本体5做成一体件，通常是将火盆本体54的侧壁冲压出进口53及进口的导引壁55，在导引壁和火盆本体5的侧壁之间焊接固定上连接板56，构成了导风罩54。火盆本体5在中间部位布置有中空的进气筒柱6，进气筒柱6的下端进口和底座1的空间连通，进气筒柱6的侧壁上段分布有出气孔61。通常在火盆本体5的中间部位开有中心气孔57，火盆本体5的底部围绕着中心气孔分布有漏孔52，进气筒柱6可以采用圆台形，就是筒柱的直径从上而下逐渐增大的，使火盆本体5通过中心气孔和进气筒柱配合而套置在进气筒柱6上，进气筒柱6的下端穿过底盘2，使进气筒柱6的下端进口和底座1的空间连通，通常底盘2的底面开有中心孔23，并沿着中心孔23成型出固定环24，使进气筒柱6的下端进口套在固定环24上，固定在底盘2上，同时与底座1的空间连通，进气筒柱6的下端进口分布有配合的接灰盘8。另有一外壳3，呈现筒体形状，直径要比火盆本体5大一圈，从而可以使火盆本体5套在外壳3里，使火盆本体5和外壳3之间形成气流通道，与旋风进口53连通。外壳3搁置固定在底盘2口沿的环形挡板22上，使火盆本体5和外壳3都布置在底盘2上，针对火盆本体的漏孔52，底盘2中下方设置有接灰盘8，通常接灰盘8尺寸大于火盆本体5的直径，接灰盘8中间部位开有中心固定孔81，套置在进气筒柱6上。底座1内衬有隔热板4，其在底座1内，针对着接灰盘8中间部位的中心固定孔81布置有隔热板4，隔热板4要大于中心固定孔81的尺寸，底盘2底面通过连接脚固定住接灰盘8，并使接灰盘8和底盘2底面之间存在间隙空间，便于进气。最后，外壳3的下部、底盘2及底座1的侧壁圆周面上分别分布进气孔31、21、11，进气孔是采用纵向延伸的长条孔。
其工作原理是，火盆采用燃气原理实现了三部分进气：
第一部分进气A为中间部分的进气表示，直接通过火盆底部进气给木柴或碳提供第一次燃烧的氧气，又因为火盆的深度而形成一个深巷吸风效果，大大提高了空气的进入量，使燃料充分燃烧；
第二部分进气B为上面部分的，形成旋转气流，压制火焰在火盆内旋转燃烧，充分给未燃烧的部分提供充足的氧气，并将火焰形成旋转效果，向火盆中间聚集；
第三部分进气C为下面部分的进气表示，通过中间直通底部的圆锥筒进气，然后从上部的小孔排出来进一步给燃烧提供第三部分空气，让燃烧的更充分；
三次进气的效果也将会在外观上给木柴或碳的燃烧表现出如燃气炉头的效果，让燃烧更充分，火焰更大。主要表现为：燃烧充分，火焰较大，火焰有明显的旋转，中间圆锥孔将会形成燃气炉头的孔焰效果，外面美观。
由于大大提高旋风进气量，强化旋风效果，利用旋风原理压制火焰乱窜，延长在火盆里的燃烧时间，使火焰充分燃烧，减少烟尘，并最后获得经济而环保的效果，参见图7。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明技术原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
