优选的， 所述的外出火圈 2031和外焰挡火圈 2032 为同心圆环状。
优选的， 所述的内出火圈 2061和内焰挡火圈 2062为同心圆环状。
优选的，所述的外焰环圈 203与上壳体 205之间设有的稳焰圈 212与所述外焰环圈 203 同心。
所述凸腔 2072的外壁将所述的下壳体内腔围合成环形全预混腔 211， 已经预混过的气 体从所述进气座 209进入后， 在气流导向板 2081的引导下， 顺着环形全预混腔 211稳定进 气； 气体在全预混腔 211内进一步混合后穿过隔板 207上的第一连通孔 2071进入所述的燃 气分配腔 204; 进入所述燃气分配腔 204内的气体， 不断分流进入旁侧的内焰环圈 206中， 一部分气体水平方向进气在内出火孔处燃烧， 另一部分依次穿过引流圈 213、 设置在上壳体 205上的第二连通孔 2051进入所述外焰环圈 203的燃气输送通道， 在外出火孔处燃烧。

所述的外焰环圈 203由外出火圈 2031和外焰挡火圈 2032层叠构成，所述外出火圈 2031 上有自其外缘向内延伸的第二槽 20311， 所述外焰挡火圈 2032 上设有连通所述的第二槽 20311内端的通孔 20321，所述外出火圈 2031上的第二槽 20311内端相互贯通形成垂直方向 上的第二燃气输送通道， 由第二连通孔 2051进入的气体进入第二燃气输送通道后不断分流 给旁侧的外出火孔进行燃烧。
所述的外焰环圈 203与上壳体 205之间设有稳焰圈 212，所述的稳焰圈 212上有自其外 缘向内延伸的第四槽 2121， 所述的稳焰圈 212具有和外出火圈 2031相同的结构， 但所述第 四槽 2121的开口宽度窄于外出火圈 2031上的第二槽 20311的开口宽度， 所述的稳焰圈 212 以及位于其上下两面的外焰挡火圈 2032和上壳体 205构成一个火孔面积较小的出火孔， 该 出火孔能消耗一部分的燃气，分担一部分外焰环圈 203的燃气输送通道中的气体压力，保证 了外焰环圈 203中的外出火孔燃烧时不会出现离焰的情况。
引流圈 213由一片或者多片外出火圈 2031层叠构成，引流圈 213上的第三槽 2131对齐 后构成贯通燃气分配腔 4和外焰环圈的 3的燃气输送通道的气体通道，通过改变用于层叠出 引流圈 213的外出火圈 31的数量， 能调节外焰环圈 3的进气长度， 从而改变气体从燃气分 配腔 4内进入外焰环圈 3的燃气输送通道过程中的压力损耗量，起到调节外焰环圈 3的燃气 输送通道的进气压力的作用， 保证外出火孔燃烧的稳定性。
所述的内焰环圈 206的下部垫有一定的内焰挡火圈 2062，主要是为了保证内焰环圈 206 的高度适合于上壳体内腔的高度， 满足固定需要。

所述的大环挡气圈 214从上表面气密地封盖内焰环圈 206，保证了进入外焰环圈 203的 气体必须经过引流圈 213。
内出火孔是由内焰挡火圈 2062和内出火圈 2061交替层叠构成的，通过改变每一个交替 层中内焰挡火圈 2062或内出火圈 2061的数量， 比如， 利用多片对齐后的内出火圈 2061和 内焰挡火圈 2062进行交替层叠， 可以增大内出火孔的出火面积， 亦即提高内出火孔的燃烧 效率， 反之可以降低内出火孔的燃烧效率； 同理， 还可以调节外出火孔的燃烧效率， 从而有 效实现燃烧器燃烧效率的简便调节。
内出火孔和外出火孔共用燃气分配腔 204进气， 有效保证外出火孔有足够的气体补给 量， 这是使用独立的进气通道给外出火孔供气所不能达到的效果。
在使用一些锅底较小的锅子时，为防止锅底将燃烧器堵死，在所述上顶盖 202上设有防 止锅底完全封死燃烧器顶部的安全柱 210， 优选的， 所述的安全柱 210设计为能直接套设在 销 201顶部的空心柱体。
