如图1所示，建立图中的坐标系，以火盖100面向锅具的一侧为上，背对锅具的一侧为下。
本发明主要提出一种火盖100，主要应用于燃烧器（主要用于燃烧厨具中）中，以在燃气灶使用过程中，减少火焰喷出时的回火等现象，以使自火盖100喷出的火焰更加稳定、均匀，以提高燃气的燃烧率和火焰的稳定性。该燃烧厨具是指，如燃气灶、燃气烤箱等，通过燃烧气体以对锅具或者食物加热的厨具。
以下将主要描述火盖100的具体结构。
参照图1至图9，在本发明实施例中，该火盖100具有燃气腔192，连通所述燃气腔192和燃气管路的进气孔191，以及与所述燃气腔192连通的燃烧火孔；
所述燃烧火孔包括外环火孔150，所述外环火孔150位于所述火盖100的周缘，所述外环火孔150包括沿所述火盖100周向开设的稳焰周槽151，以及位于稳焰周槽151上方的上稳焰槽152，所述稳焰周槽151与所述上稳焰槽152连通。
具体地，本实施例中，火盖100大致呈飞碟状设置，具体地，火盖整体呈扁平状设置，在火盖100的顶部和的底部都具有凸出部分，使得火盖100的燃气腔192也呈飞碟状设置。火盖100包括外盖110和内盖120，外盖110具有一端敞口的腔体，该敞口沿火盖100的厚度方向设置，敞口位于外盖110的底部。外盖110的形状与敞口适配，在敞口周缘，外盖110具有供内盖120安装的安装凸台，内盖120面向外盖110的一侧与凸台贴合，以密封形成封闭的燃气腔192。
外环火孔150沿火盖100中部的外缘开设，稳焰周槽151沿火盖100的周向开设，上稳焰槽152沿火盖100的厚度方向开设。关于上稳焰槽152，沿火盖100的径向方向的延伸长度为槽长，沿火盖100厚度方向的延伸长度为槽深。稳焰周槽151和上稳焰槽152均与燃气腔192连通，当然，在一些实施例中，也可以是其中的一个与燃气腔192连通，而另一则通过与前一个连通来获取燃气。稳焰周槽151和上稳焰槽152连通后呈T字形设置，更为准确的说，根据图1中的坐标系，呈倒“T”字形设置，稳焰周槽151（槽长）为“T”字形的横，上稳焰槽152（槽深）为“T”字形的竖。当然，在一些实施例中，也可以拼接形成“L”形。
本实施例中，通过将外环火孔150设置为由上稳焰槽152和稳焰周槽151组成，使得当燃气自燃气腔192从外环火孔150喷出时，火焰将在上稳焰槽152和稳焰周槽151内扩张，由于火焰在燃烧时，体积增加，而上稳焰槽152和稳焰周槽151恰好给了火焰燃烧时扩展体积所需要的空间，使得火焰在喷出时有足够的空间，从而避免出现回火现象，使得燃气可以在燃烧过程中充分的与空气接触以燃烧充分；同时，由于燃气在燃烧时有充分的空间，使得火焰在喷出时避免由于空间太小而被挤压，使得火焰喷出的更加稳定。
为了进一步增加火焰的扩展空间，使得燃气燃烧更加充分，火焰喷出后更加稳定，所述上稳焰槽152贯穿所述火盖100厚度方向的上部，以使所述稳焰周槽151通过所述上稳焰槽152与所述火盖100厚度方向的外部连通。
本实施例中，上稳焰槽152的一侧与稳焰周槽151连通，上稳焰槽152的顶部贯穿火盖100的顶部，使得上稳焰槽152的顶部与空气连通，当燃气燃烧时，火焰可以从上稳焰槽152的上部喷出，大幅增加了燃气燃烧的空间，从而使得燃气的燃烧更加充分，火焰更加稳定。此时，火焰可以沿火盖100的周缘喷出的同时，还可以从火盖100的顶部靠近边缘的位置喷出。
为了适应多种火焰的需求，所述稳焰周槽151的长度方向与所述上稳焰槽152的长度方向呈夹角设置，所述夹角大于零度，且小于180度。即上稳焰槽152自火盖100的边缘向中部延伸的延伸方向，与火盖100边缘的切线方向呈角度设置。二者之间的夹角以90°为例，即当后盖的外缘呈圆周设置时，上稳焰槽152沿火盖100的径向延伸。
所述稳焰周槽151的长度方向与所述上稳焰槽152的槽深方向呈夹角设置，所述夹角大于零度，且小于180度；其中，所述上稳焰槽152的槽深方向为其在所述火盖100厚度方向的延伸方向。上稳焰槽152的槽壁倾斜设置于火盖100内，槽壁的壁面与火盖100的顶面或者底面倾斜。以槽壁的壁面与稳焰周槽151的延伸方向相互垂直为例。
在一些实施例中，为了给燃烧的火焰提供更大的空间，所述稳焰周槽151的槽宽大于或者等于所述上稳焰槽152的槽宽。
为了给燃烧的火焰提供更大的空间，并且是火焰更加均匀，所述外环火孔150的数量为多个，多个所述外环火孔150沿所述火盖100的周向排列。通过将外环火孔150沿火盖100的周向均匀排列，使得火焰均匀的从火盖100的四周喷出，便于多锅具或者食物均匀加热。
在一些实施例中，沿所述火盖100的周向开设有传火槽，所述传火槽连通相邻两所述外环火孔150的稳焰周槽151，以使相邻的所述外环火孔150连通。本实施例中，传火槽与稳焰周槽151拼接后形成一个圆环，即稳焰周槽151和传火槽位于统一圆环上，二者可以一起加工成型，或者说传火槽为相邻的两个稳焰周槽151相互延伸形成。通过传火槽的设置，使得相邻的外环火孔150之间可以通过传火槽传火，当外环火孔150中的任意一个点燃时，其余的外环火孔150通过传火槽快速点燃。另外，传火槽增加了火焰喷射的空间，在爆发时有更大的空间可以活动，从而有利于提高燃气的燃烧率和火焰的稳定性。即传火槽不仅可以起到传火的作用，还可以使燃气燃烧的更加充分，火焰更加稳定、均匀。
在一些实施例中，为了进一步的增加火焰喷出的稳定性，提高燃气的燃烧率，所述外环火孔150还包括下稳焰槽153，所述下稳焰槽153位于所述稳焰周槽151的下方，所述稳焰周槽151与所述下稳焰槽153连通。
本实施例中，下稳焰槽153与稳焰周槽151之间的连接关系和位置关系，与上稳焰槽152与稳焰周槽151之间的连接关系和位置关系相类似，与上稳焰槽152位于稳焰周槽151上部不同的是，下稳焰槽153位于稳焰周槽151的下方。通过将外环火孔150设置为由上稳焰槽152、下稳焰槽153和稳焰周槽151组成，使得当燃气自燃气腔192从外环火孔150喷出时，火焰将在上稳焰槽152、下稳焰槽153和稳焰周槽151内扩张，由于火焰在燃烧时，体积增加，而上稳焰槽152、下稳焰槽153和稳焰周槽151恰好给了火焰燃烧时扩展体积所需要的空间，使得火焰在喷出时有足够的空间，从而避免出现回火现象，使得燃气可以在燃烧过程中充分的与空气接触以燃烧充分；同时，由于燃气在燃烧时有充分的空间，使得火焰在喷出时避免由于空间太小而被挤压，使得火焰喷出的更加稳定。
为了进一步增加火焰的扩展空间，所述下稳焰槽153贯穿所述火盖100厚度方向的下部，以使所述稳焰周槽151通过所述下稳焰槽153与所述火盖100厚度方向的外部连通。
本实施例中，下稳焰槽153的一侧与稳焰周槽151连通，下稳焰槽153的底部贯穿火盖100的底部，使得下稳焰槽153的底部与空气连通，当燃气燃烧时，火焰可以从下稳焰槽153的下部喷出，大幅增加了燃气燃烧的空间，从而使得燃气的燃烧更加充分，火焰更加稳定。此时，火焰可以沿火盖100的周缘喷出的同时，还可以从火盖100的底部靠近边缘的位置喷出。
为了适应多种火焰的需求，所述稳焰周槽151的长度方向与所述下稳焰槽153的长度方向呈夹角设置，所述夹角大于零度，且小于180度。
即下稳焰槽153自火盖100的边缘向中部延伸的延伸方向，与火盖100边缘的切线方向呈角度设置。二者之间的夹角以90°为例，即当后盖的外缘呈圆周设置时，下稳焰槽153沿火盖100的径向延伸。
所述稳焰周槽151的长度方向与所述下稳焰槽153的槽深方向呈夹角设置，所述夹角大于零度，且小于180度；其中，所述下稳焰槽153的槽深方向为其在所述火盖100厚度方向的延伸方向。下稳焰槽153的槽壁倾斜设置于火盖100内，槽壁的壁面与火盖100的顶面或者底面倾斜。以槽壁的壁面与稳焰周槽151的延伸方向相互垂直为例。
当然，可以理解的是，为了上稳焰槽152和下稳焰槽153可以更好的配合，所述下稳焰槽153的槽深方向与所述上稳焰槽152的槽深方向相同，且二者连通于所述稳焰周槽151的同一位置。此时，由上稳焰槽152、下稳焰槽153和稳焰周槽151所组成的外环火孔150呈“十”字形设置。
在一些实施例中，为了使火焰更加稳定，由于火焰有朝上喷射的趋势，通过将所述上稳焰槽152的槽深大于所述下稳焰槽153的槽深。使得上稳焰槽152的空间大于下稳焰槽153的空间，当火向上经过上稳焰槽152时，由于上稳焰槽152有足够的空间，使得上稳焰槽152可以很好的控火和导火。在一些实施例中，所述上稳焰槽152、下稳焰槽153以及所述稳焰周槽151均与所述燃气腔192连通。当然，在一些实施例中可以只有其中一个或者两个与燃气腔192连通。
为了进一步提高火盖100的工作效率，所述火盖100还具有内环火孔131，所述内环火孔131与所述燃气腔192连通；所述火盖100的中部开设有沿所述火盖100的厚度方向贯穿所述火盖100的中心孔，所述内环火孔131设置在所述中心孔周缘的火盖100上。即内环火孔131开设在火盖100的中部位置，通过在火盖100的中部位置设置内环火孔131，使得锅具在被加热时，可以接收到周边和中部火焰的加热。
为了在底部均匀的加热，所述中心孔周缘的所述火盖100上间隔设置有若干喷火凸台130，所述喷火凸台130的一侧开设有所述内环火孔131，另一侧设置有导火斜面132，以使后一所述喷火凸台130上的内环火孔131的出火口朝向前一所述所述喷火凸台130的导火斜面132。当火焰喷射到导火斜面132时，可以将火焰均匀的散开，均匀的集中在锅底部。
在一些实施例中，所述火盖100还具有中环火孔160，中环火孔160与所述燃气腔192连通；所述中环火孔160位于所述内环火孔131和所述外环火孔150之间。在火盖100工作过程中，内环火孔131的燃气首先被点燃，经过导火斜面132的引导，使得中环火孔160内的燃气快速的被点燃，由于中环火孔160的出火口朝向外环火孔150，外环火孔150的燃气也快速的被点燃，从而实现火盖100上三环火的稳定燃烧。
在一些实施例中，为了提高外环火孔150的点燃效率，以及增加外环火孔150距内环火孔131的距离，所述火盖100具有燃气腔192，连通所述燃气腔192和燃气管路的进气孔191，以及与所述燃气腔192连通的燃烧火孔；所述燃烧火孔包括自所述火盖100周缘向中部依次排列的外环火孔150、中环火孔160，以及内环火孔131；所述中环火孔160的出火口朝向所述外环火孔150的方向设置。
本实施例中，通过将中环火孔160的出火口朝向外环火孔150，使得自中环火孔160喷出的火焰朝向外环火孔150延伸。通过中环火孔160的设置，使得外环火孔150在与内环火孔131之间的距离增加时，外环火孔150依然可以通过环火孔的传递而被快速点燃。
在一些实施例中，所述中环火孔160距所述内环火孔131的距离，小于所述中环火孔160距所述外环火孔150的距离。内环火孔131的火焰沿火盖100中部周向喷射，使得火焰均匀的集中在火盖100的顶部，此时，内环火孔131和中环火孔160之间的距离不宜过大，避免出现传火缓慢的问题。由于中环火孔160的出火口朝向外环火孔150，使得外环火孔150可以根据实际需求来设置一个均中环火孔160相对较远位置，使得外环火孔150可以均匀的加热锅具的周边。如此设置，有利于充分合理的利用火盖100的空间和合理的排布调节火焰的燃烧区域。
为了增加中环火孔160的喷射距离，所述中环火孔160包括中进气通道161和中喷火通道162，所述中进气通道161与所述燃气腔192的连通面积，小于所述中喷火通道162与外部的连通面积。从大空间的燃气腔192，到小面积的中进气通道161，使得燃气在传输过程中加压，从小面积的中进气通道161，到大面积的中喷火通道162，使得火焰更加均匀的向四周喷射。如此，既增加了火焰的喷射距离，又增加了火焰的喷射范围。
中进气通道161和中喷火通道162的形式可以有很多，下面举一个例子说明，所述中气通道包括若干沿所述火盖100周向排列的孔结构；所述中喷火通道162包括沿所述火盖100周向设置的喷火槽。
在一些实施例中，为了提高中部喷火的均匀性，所述火盖100的中部形成有与外部燃气管路连通的连接管180，所述中进气通道161沿所述连接管180的周向排布；所述内环火孔131的内进气通道位于所述中进气通道161与所述连接管180之间。
为了增加内环火孔131和中环火孔160之间的燃气稳定性，所述火盖100的中部形成有与外部燃气管路连通的连接管180，所述燃气腔192的顶壁绕所述连接管180形成有集气槽170，所述中环火孔160和所述内环火孔131开设在所述集气槽170内。由于中环火孔160和内环火孔131均设置在集气槽170中，并均位于火盖100的顶部，使得内环火孔131和中环火孔160位置的气压相当，引火便捷。
请参照图10至图13，该火盖310b包括：盖本体311b（所述盖本体311b即所述外盖110），内设有燃气腔312b，所述盖本体311b的外周面开设有外环火孔313b；以及多个导热凸缘314b，位于所述燃气腔312b内，相邻两所述导热凸缘314b之间形成导流槽315b，所述导流槽315b与所述外环火孔313b连通。
具体的，火盖310b的盖本体311b内设置有燃气腔312b，盖本体311b的外周面开设有外环火孔313b，该外环火孔313b开设有多个，多个外环火孔313b优选沿盖本体311b的周向呈间隔地排布。盖本体311b的下侧设置进气口321，燃气从进气口321进入燃气腔312b内，燃气腔312b内的燃气在通过外环火孔313b排出燃烧。
在燃气腔312b内，相邻两导热凸缘314b之间形成导流槽315b，燃气腔312b内的燃气经过导流槽315b后再从外环火孔313b排出、燃烧。可以理解的是，与燃气直接从燃气腔312b流向外环火孔313b的方案相比，本实施例中燃气腔312b内的燃气需要先经过导流槽315b才能流向外环火孔313b，此时燃气的流动截面积减小，燃气在火盖310b内的燃气分压增大，进而使得燃气在外环火孔313b处的气体流速增大，进而有效避免了火盖310b发生回火现象的几率。
同时，在燃气燃烧过程中，火盖310b受到高温火焰的炙烤，进而火盖310b的温度较高，由于燃气腔312b内设置有导热凸缘314b，也使得燃气在流动过程中会与导热凸缘314b进行换热，即燃气与燃气腔312b的腔壁的接触面积增大，进而提升了燃气在燃气腔312b内的初始温度。如此，可实现对燃气的有效预热，燃气在燃气腔312b内的温度提高后，燃气在燃烧时的火焰传播速度也加快了，进而明显减小发生离焰等不正常燃烧现象的几率，也使得燃气的燃烧更加充分，燃气的燃烧效率得到有效提升。
导流槽315b还起到导流燃气的作用，进而使得燃气从燃气腔312b内通畅地流向外环火孔313b处，改善了燃气的流动性，更利于燃气的充分燃烧。
进一步地，本实施例中，导流槽315b沿盖本体311b的径向，自外环火孔313b向盖本体311b的中部延伸，如此导流槽315b的延伸方向与燃气的流动方向一致，降低导流槽315b对燃气的流动阻力，进而有利于提高燃气在导流槽315b内的流动性。
在自盖本体311b的中部向外环火孔313b延伸方向上，导流槽315b的槽宽呈渐缩设置。如此，导流槽315b靠近外环火孔313b处的槽宽较小，在靠近外环火孔313b的方向上，燃气在导流槽315b的流动截面积减小，进而可提高燃气在外环火孔313b处的流速，减少发生回火现象的几率。
本实施例中，为了使得火盖310b上各个位置的燃烧相对均匀，上述外环火孔313b沿盖本体311b的周向间隔地设置有多个；可以理解的是，上述导流槽315b的数量为多个，每一外环火孔313b至少与一导流槽315b连通；其中，一个外环火孔313b可以对一个导流槽315b，或者，一外环火孔313b对应多个导流槽315b，进而使得外环火孔处的燃气分压更大，使燃气在外环火孔313b处的气体流速更快，。以有效避免火盖310b发生回火现象。为了提高导流槽315b的分流效果，以及使得外环火孔313b处的燃气的出气量相对均匀，一个外环火孔313b对应一个导流槽315b设置。
为了减少燃气进入导流槽315b时的阻力，本实施例中，导热凸缘314b在靠近盖本体311b的中心位置处的部分呈圆滑过渡。如此一来，得燃气腔312b的燃气沿着导热凸缘314b靠近盖本体311b的中心位置处的过渡面分别流入两导流槽315b内，进而保障了导流槽315b对燃气的分流效果，减少了燃气进入导流槽315b的阻力，增强了燃气的流动性。当然，于其他实施例中，上述导热凸缘314b在靠近盖本体311b的中心位置处呈尖角状设置，此时导热凸缘314b在在靠近盖本体311b的中心位置处形成呈夹角设置的导流斜面，可使得燃气腔312b的燃气沿着导流斜面流入导流槽315b内，进而也可保障了导流槽315b对燃气的分流效果，实现减少了燃气进入导流槽315b的阻力、增强燃气流动性的目的。
另外，为了使得导流槽315b内燃气顺畅地流入外环火孔313b，该导流槽315b远离盖本体311b中心的槽壁面呈凹面设置，且外环火孔313b开设于凹面的顶点处。如此，导流槽315b内的燃气沿着该凹面流动、并向外环火孔313b处汇聚，进而便于燃气从外环火孔313b排出，降低了导流槽315b对燃气流动的阻力。
进一步地，请参照图14和图15，考虑到火盖内部设有燃气腔300c，火盖上设有内环火孔230c、中环火孔240c和外环火孔250c，因此火盖的结构和形状较为复杂，为了便于生产成型火盖，本实施例中，所述火盖由内盖100c和外盖200c两部分组成。具体地，所述火盖包括内盖100c和扣合固定于所述内盖100c的外盖200c，所述外盖200c和所述内盖100c之间形成所述燃气腔300c；所述外环火孔250c开设于所述外盖200c的周缘，所述中环火孔240c和所述内环火孔230c均开设于所述外盖200c，且所述内环火孔230c和所述中环火孔240c自内向外依次设置，如此，外盖200c和内盖100c的结构相对简单，从而能够方便成型后脱模，因此能够便于生产成型火盖。
然本专利的设计不限于此，于其他实施例中，所述火盖还可为一体成型设置。
进一步地，请继续参照图15，为了使得内环火孔230c喷出的火焰能够对被加热炊具集中加热，从而聚集热量提高热效率，本专利一实施例中，所述外盖200c包括盖体210c和设于所述盖体210c中部的出火台220c，所述出火台220c的中部设有自下向上、呈渐扩设置的加热面，所述加热面上开设有所述内环火孔230c。由于开设有内环火孔230c的加热面呈自下向上的扩口结构设置，因此经内环火孔230c喷出的火焰具有向内聚集的效果，从而能够集中供火，从而提高热效率。
进一步地，请参照图16，为了使得内环火孔230c形成立体加热效果，本专利一实施例中，所述内环火孔230c在所述加热面上、沿上下方向间隔地设有至少两排。如此，内环火孔230c在上下方向形成至少两排火焰，因此能够形成立体加热效果，进而使得被加热炊具的加热效果更为均匀。
进一步地，请继续参照图16，为了使得内环火焰具有小火不熄火的效果，本专利一实施例中，所述加热面上凸设有多个内环凸起221c，多个所述内环凸起221c沿所述加热面的周向间隔分布，所述内环火孔230c开设于所述内环凸起221c。由于内环凸起221c凸设于所述加热面且多个内环凸起221c沿所述加热面的周向间隔分布，因此内环凸起221c具有防风效果，从而使得内环火焰在微弱的小火状态下也不会熄灭，从而能够获得稳定的小火加热效果。
进一步地，请继续参照图16，为了提高内环火焰的加热效率，本专利一实施例中，所述内环凸起221c具有在所述加热面的周向呈向心旋转结构设置的第一台阶面，所述内环火孔230c为开设于所述第一台阶面上的圆形孔。由于第一台阶面在加热面的周向呈向心旋转结构设置，内环火孔230c开设在第一台阶面上，因此，内环火焰呈现出向内旋火的形状，从而能够将内环火焰的热量向内聚集，从而提高内环火焰的加热效率。
在此需要说明的是，在其他实施例中，所述内环火孔230c还可以矩形、椭圆形、半月形、环形、星形、心形、缝隙状中的一种或多种设置。
进一步地，请仍参照图16，为了促进热量向中心聚集，所述内环凸起221c还具有与所述第一台阶面呈夹角设置的第二台阶面，所述第二台阶面呈光滑设置以反射相邻的内环火孔230c的火焰。如此，内环火焰的热量可以通过第二台阶面向内进行反射聚集，因此能够显著地提高内环火焰的加热效率。
作为一种优选方式，所述第二台阶面上设有热反射涂层，具体地，所述热反射涂层为二氧化钛粉体和环氧树脂涂料的混合物，二氧化钛具有高折光性，因此，由二氧化钛制成的热反射涂层具有高的热量反射率。
进一步地，请参照图17至图20，为了使得从中环火孔240d喷出的火焰更为均匀，本专利一实施例中，所述中环火孔240d呈圆环形设置，具体地，外盖200d包括盖体210d和设于所述盖体210d中部的出火台220d，所述出火台220d的外周壁与所述盖体210d的内侧壁呈间隔设置、以在所述出火台220d和所述盖体210d之间形成所述中环火孔240d。其中，所述出火台220d的外周壁和盖体210d的内侧壁均呈圆柱面设置，因此能够形成圆环形的中环火孔240d，由于该圆环形的中环火孔240d呈连续的缝隙状，因此能够使得中环火孔240d各处的出火强度均匀一致。
进一步地，请参照图19，现对中环火孔240d的出火口朝向所述外环火孔250d设置的具体结构进行详细说明，本实施例中，所述出火台220d的外周壁的直径自下向上递增设置，因此出火台上部的外壁面能够形成自下向上渐扩设置的导火面，又因为导火面与盖体210d之间形成所述中环火孔240d，因此能够使得中环火孔240d的出火口朝外设置，从而能够改善中环火孔240d向外环火孔250d一侧的传火效果。
进一步地，请参照图20，为了提高中环火孔240d火焰的喷出距离，本专利一实施例中，所述出火台220d上设有与所述中环火孔240d相连通的进气孔222d，所述进气孔222d沿周向的分布密度大于所述内环火孔230d沿周向的分布密度。具体地，由于中环火孔240d的进气孔222d的分布密度大于内环火孔230d，因此能够提高中环火孔240d的进气量，进而能够提高中环火孔240d的火焰的喷出距离，促进中环火孔240d的火焰传递至外环火孔250d。
进一步地，请参照图19，为了促进中环火孔240d的火焰向外环火孔250d一侧喷出，本专利一实施例中，所述出火台220d的顶部凸出所述盖体210d的顶面设置，且所述出火台220d的顶部向外延伸设有引火凸缘223d，所述引火凸缘223d间隔设于所述中环火孔240d的上侧。由于引火凸缘223d向外延伸设置，因此中环火孔240d的火焰在引火凸缘223d的作用下能够向外环火孔250d一侧喷出。此外，由于引火凸缘223d能够形成截面积较小的出火缝隙，因此，中环火孔240d的火焰经出火缝隙喷出后速度大、距离远。
进一步地，请继续参照图19，为了避免堵塞中环火孔240d，本专利一实施例中，所述引火凸缘223d的外侧面凸出于所述中环火孔240d的孔口的外侧边。如此，当汤水自引火凸缘223d向下滴落时，能够避免汤水渗入中环火孔240d，因此能够避免汤水、油渍等堵塞中环火孔240d，进而能够使得中环火孔240d保持良好的传火效果。
进一步地，请仍参照图19，为了使得中环火孔240d喷出的火焰能够有效地传递至外环火孔250d，本专利一实施例中，所述外环火孔250d开设在所述外盖200d的周缘，所述外环火孔250d和所述中环火孔240d之间设有传火斜面。具体地，所述外盖200d呈倒扣的碟形设置，中环火孔240d靠近外盖200d的顶部设置，外环火孔250d开设在外盖200d的周缘，如此，中环火孔240d和外环火孔250d之间能够形成直径自上向下呈递增设置的传火斜面，由于火焰倾向于贴附于传火斜面向外传递，因此能够使得中环火孔240d喷出的火焰有效地传递至外环火孔250d。
本发明还提出一种燃烧器，该燃烧器包括引射管200和火盖100，该火盖100的具体结构参照上述实施例，由于本燃烧器采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。其中，所述引射管200包括供气端210、安装端220以及连通所述供气端210和所述安装端220的隐射段230，所述供气端210与燃气通道连通；所述火盖100与所述安装端220连接，以使所述燃气通道与所述火盖100的燃气腔192连通。
值得强调的是，本发明公开一种十字槽型、T型槽稳焰技术。本稳焰技术在于在出火口位置设置十字交叉、T型出火口，此种出火结构可以形成中心主火，逐步向外形成值班火焰的火型，横向传火快捷稳定。竖向加强稳焰，也可以分流液体起到火孔防堵效果。火焰燃烧更稳定持久。加工方便快捷，省时省力，效率高、成本低。
参照图9，本发明还提出一种燃烧厨具，该燃烧厨具包括：面板300；锅支架400，锅支架400用于支撑锅具，锅支架400设于面板300上方；以及燃烧器，燃烧器设于锅支架400的下方；燃烧器位于面板300上方，且安装于面板300上；或燃烧厨具还包括位于面板300下方的底壳，燃烧器位于面板300的下方，且安装于底壳上。该燃烧器的具体结构参照上述实施例，由于本燃烧厨具采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。其中，该燃烧厨具可以是燃气灶具或燃气烤箱等产品。
需要说明的是，上述燃烧器可位于面板300上方或面板300下方，其中，当燃烧器位于面板300上方时，燃烧器安装于面板300上，此时燃烧器位于锅支架400和面板300之间，空气从面板300的上方进入燃烧器内；或者，该燃烧厨具还包括位于面板300下方的底壳，燃烧器位于面板300的下方，燃烧器安装于底壳上，空气从面板300的下方进入燃烧器内。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是在本发明的发明构思下，利用本发明说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本发明的专利保护范围内。
