下面结合附图和实施例对本发明作进一步说明：
如图所示， 这种高效节能环保型燃烧器， 包括炉芯 1、 火盖 3、 炉盘和炉头 7， 在炉芯 1 上设有四个炉芯出火孔凸块 1-1，每个炉芯出火孔凸块 1-1上设有炉芯出火孔 1-2，炉芯出火 孔凸块 1-1与炉芯出火孔凸块 1-1之间设有炉芯进气通道 2; 火盖 3上设有八个火盖出火孔 凸块 3-1， 每个火盖出火孔凸块 3-1上设有火盖出火孔， 火盖出火孔凸块 3-1与炉芯出火孔 凸块 1-1之间设有火盖进气通道 4， 每个炉芯出火孔 1-2的出火位置正好朝向相应的一个火 盖进气通道 4的通道口位置， 火盖进气通道 4和炉芯进气通道 2均呈内大外小的喇叭口状。
所述的火盖出火孔凸块 3-1和炉芯出火孔凸块 1-1均是由四个四边形斜面和一个顶部平 面构成的凸块（可以是其他多边形结构）； 炉芯出火孔凸块 1-1的外圈斜面上设置有炉芯出火 孔 1-2，火盖出火孔凸块 3-1的外圈斜面上设置有火盖外圈出火孔 3-2、 内圈斜面上设置有火 盖内圈出火孔 3-3、一侧斜面设置有火盖侧面出火孔 3-4， 一个炉芯出火孔凸块 1-1上设有火 盖侧面出火孔 3-4的一侧斜面与另一个相邻炉芯出火孔凸块 1-1上没有设置火盖侧面出火孔 3-4的一侧斜面之间设置有火盖进气通道 4。所述的火盖出火孔凸块 3-1的外圈斜面与水平面 呈 30度角， 内圈斜面与水平面呈 60度角， 有火盖侧面出火孔 3-4的一侧斜面与水平面呈 45 度角。
本专利的原理是： 通过出火孔的角度调置来降低到锅底距离， 这种调整虽然会增加热效 率， 但是必定会带来进二次空气时与空气有效接触不够的问题， 因此传统的燃烧器均不敢轻 易降低到锅底距离。 而本专利釆用通过多种结构的改进来解决空气有效接触不够的问题， 主 要是通过出火孔的交叉排列使得炉芯火焰和火盖内圈火焰交叉， 增加了空气接触面积使锅底 受热均衡。
所述的炉盘包括用四个螺丝固定连接在一起的炉盘中 5和炉盘底 6，炉盘上安装有炉芯 1 说 明 书 和火盖 3， 炉盘中 5上设置有进气通孔 8、 与火盖 3上的卡槽呈定位配合的炉盘定位柱 5-1 ; 炉盘中心设置有进煤气通道 B10， 进煤气通道 B10与炉芯出火孔 1-2、稳焰槽 5-8相连通； 炉 芯 1上设置有炉芯定位块 1-3， 炉盘上设置有与炉芯定位块 1-3配合的炉盘定位槽 5-2、与炉 芯 1呈定位配合的炉盘定位凸台 5-7。 炉盘中 5中心与外圈之间通过连接件 5-9连接在一起， 连接件 5-9的表面为内高外低的斜面结构， 该结构增加了斜面最低处到火盖内圈出火孔 3-3 的距离， 从而在进二次空气时也帮助增加与空气的有效接触。 所述的炉盘中 5上设置有与点 火孔 5-5相连通的点火针定位槽 5-3， 与熄火保护孔 5-6相连通的热电偶定位槽 5-4。
炉盘的设计原理说明： 火盖 3安装在炉盘上， 通过炉盘定位柱 5-1的定位作用来限定火 盖 3沿轴线不能在炉盘上转动， 炉芯 1安装在炉盘中心， 是通过炉芯定位块 1-3和炉盘定位 槽 5-2实现定位控制轴向转动； 通过上述二个定位结构来保证每个炉芯出火孔 1-2的出火位 置正好朝向相应的一个火盖进气通道 4的通道口位置。 为了保证稳焰燃烧， 炉芯 1与炉盘中 心之间的间隙必须要均匀，才能通过稳焰槽 5-8和炉芯 1与炉盘中心之间的间隙向外漏煤气。 现有技术是通过三点定位来实现定位和间隙均匀， 但是三点定位安装时非常麻烦， 要试好多 次才能顺利安装好；本专利采用一个炉芯定位块 1-3和二个炉盘定位凸台 5-7 (凸出二个点）， 与炉芯定位块 1-3构成三点定位， 安装方便； 同时通过二个炉盘定位凸台 5-7保证炉芯 1与 炉盘中心之间的间隙均匀。
所述的炉头 7包括引射管 Al l和引射管 B12， 引射管 Al l的一端设置有进风口 A15和煤 气喷嘴孔 A17， 另一端与通煤气道 A13相连通， 通煤气道 A13通过进煤气通道 A9与火盖出火 孔相连通； 引射管 B12的一端设置有进风口 B16和煤气喷嘴孔 B18， 另一端与通煤气道 B14 相连通， 通煤气道 B14与进煤气通道 B10相连通。 引射管 Al l的直径大于引射管 B12， 进风 口 A15大于进风口 B16。 本专利中引射管和进风口设计成一大一小结构， 火盖处的空气需要 量大与进风口 A15相配合， 炉芯处的空气需要量小与进风口 B16相配合， 从而保证一次空气 的有效吸入。 测试数据
