请参阅图1-图6，本发明较佳实施方式的燃烧器100包括底杯组件102、喷火器104、内火盖106、外火盖108、第一喷嘴(图未示)及第二喷嘴(图未示)。
请结合图3-5，该底杯组件102包括底杯盖114和底杯座116，该底杯盖114嵌设在该底杯座116，例如底杯盖114与底杯座116是通过铆接孔118连接。该底杯盖114包括第一面119、进气口组件120、底杯补充部122及第一混合部124。
第一面119连接该底杯补充部122及该第一混合部124。第一面119与该喷火器104相对。该第一面119上设置有底杯筋板125。本实施方式中，请结合图4，底杯筋板125的数量为四个。为了方便说明，其中两个底杯筋板125称为第一底杯筋板对，另外两个底杯筋板125称为第二底杯筋板对。第一底杯筋板对共同形成第一底杯通道126，第二底杯筋板对共同形成第二底杯通道127。
该进气口组件120包括第一进气部128、第二进气部130及连接部132，该连接部132连接该第一进气部128与该第二进气部130。该第一进气部128、该底杯补充部122及该第一混合部124依次连接。该第二进气部130穿设该底杯补充部122，该连接部132设置在该底杯补充部122的外侧壁。
请结合图3及图7，第一进气部128为大致呈水平放置的管状进气部。请结合图3 及图7，第二进气部130为相对于该第一进气部128倾斜放置的管状进气部。因此，倾斜放置的第二进气部130在结构上实现气流流畅、便于出模加工，提高燃烧器100的可制造性，降低成本。
请结合图7，该第一进气部128开设有第一进气通道134。请结合图9，该第二进气部130开设有第二进气通道136。请结合图8，该连接部132开设有连接通道138。该第二进气通道136相对于该第一进气通道134倾斜设置。倾斜设置的第二进气通道136在结构上实现气流更流畅。
该连接通道138连接该第一进气通道134及该第二进气通道136，进而使气流在该第一进气通道134及该第二进气通道136之间互通。因此，连接通道138横向连接第一进气通道134及第二进气通道136。
该第一进气通道134具有进气口140及出气口142。第一进气通道134的进气口140可与外部气源连接。该第一喷嘴安装在该第一进气通道134的出气口142。第二进气通道136具有出气口144(见图3及图7)，第二进气通道136的出气口144开设在远离连接部132的第二进气部130的一端，该第二喷嘴安装在该第二进气通道136的出气口144。因此，当燃气流入第一进气通道134时，一部分燃气通过第一喷嘴喷射至底杯补充部122，另一部分燃气通过第二喷嘴喷射出去。
本实施方式中，远离连接部132的第一进气部128外壁开设有第一工艺孔146(见图3)。该第一工艺孔146贯穿第一进气通道134，并与连接通道138连通，用来保证连接通道138的工艺可实现性。第一工艺孔146被第一堵头(图未示)堵住，保证了燃烧器100的气密性。与连接部132连接的第二进气部130的另一端开设有第二工艺孔150(见图3及图5)，该第二工艺孔150用来保证第二进气通道136的工艺可实现性，第二工艺孔150被第二堵头(图未示)堵住，保证了燃烧器100的气密性。同时，第二工艺孔150还可兼具第二进气通道136的进气口。例如，当需要双气源供气时，此时，不加工连接通道138，并打开第二堵头，将另一气源与第二工艺孔150连通即可。由于不加工连接通道138，使得第一进气通道134与第二进气通道136不连通，进而实现第一进气通道134与第二进气通道136均可单独供气。
该底杯补充部122呈扇形，第二进气部130穿设在底杯补充部122的内侧边。底杯补充部122开设有底杯一次空气补充室154。底杯一次空气补充室154贯穿底杯补充部122。该底杯一次空气补充室154通过第一喷嘴与第一进气通道134连通。第一进气部128连接在底杯补充部122的较大端，第一混合部124连接在底杯补充部122的较小端。气流从底杯补充部122的较大端方向流向底杯补充部122的较小端方向，这有利于气流的喷射。
底杯盖114还包括设置在该第二喷嘴周缘的凸筋158。该底杯筋板连接该凸筋。该凸筋158设置有防水倒角160。这样可有效避免如水、汤汁等液体进入燃烧器100的底杯盖114而堵塞喷嘴的隐患。
该第一混合部124开设有与该底杯一次空气补充室154连通的第一凹槽162(见图5)。本实施方式中，第一凹槽162被水平开设并沿第一进气部128的轴向贯穿第一混合部124。因此，第一喷嘴与第一凹槽162直通，第一凹槽162的后端(远离第一喷嘴的第一凹槽162的一端)无遮挡，方便底杯盖114的加工和模具制作，提高燃烧器的可制造性，降低成本。
该底杯座116包括依次连接的第一腔室部164、第二混合部166及第二腔室部168。该第一腔室部164与该底杯补充部122连接且开设有第一腔室170，该第一腔室170与该底杯一次空气补充室154共同形成底杯一次空气补充腔172。本实施方式中，第一腔室部164呈与第一补充部122相匹配的扇形。
该第二混合部166与该第一混合部124连接并共同形成水平文丘里管174(见图7)。第二混合部166开设有第二凹槽176，该第二凹槽176与该第一凹槽162共同形成该水平文丘里管174的混合通道178(见图7)。
该第二腔室部168开设有一次空气/燃气混合分配腔180，该一次空气/燃气混合分配腔180通过该混合通道178与该底杯一次空气补充腔172连通。本实施方式中，第二腔室部168呈扇形，第二腔室部168的弧长较第一腔室部164的弧长要大。请结合图4，一次空气/燃气混合分配腔180是从燃烧器100周边分两边折转回燃烧器100中心两侧的两个腔，因此，第一腔室部164有利于气体的混合，而第二腔室部168有利于气体的分散。
底杯座116还开设有第一安装孔182，第一安装孔182与第一腔室170、第二凹槽176及一次空气/燃气混合分配腔180间隔设置。在燃烧器100安装至燃气用具时，固定件可通过该第一安装孔182将底杯组件102固定至燃气用具。
底杯座116开设有供点火装置穿过的两个第一过孔190，底杯盖114开设有与两个第一过孔190分别对应的两个第二过孔192。两个第一过孔190分别位于第二混合部166的两侧。两个第二过孔192分别位于第一混合部124的两侧。点火装置的热电偶可依次穿设其中一个第一过孔190及其中一个第二过孔192，点火装置的点火针可依次穿设另一个第一过孔190及另一个第二过孔192。
该喷火器104设置在该底杯组件102的底杯盖114上。该喷火器104包括第二面193、外环喷火器194、内环喷火器196、竖直文丘里管198及连接筋200。
该内环喷火器196位于该外环喷火器194中。该第二面193与该第一面119相对， 该第二面193连接该外环喷火器196及该内环喷火器194。
该第二面193上设置有喷火器筋板195，该喷火器筋板195设置在该底杯筋板125上以共同形成内环一次空气补充部197。内环一次空气补充部197开设有内环一次空气补充通道199(见图8及图9)。
具体地，本实施方式中，请结合图5，喷火器筋板195的数量为四个。为了方便说明，其中两个喷火器筋195板称为第一喷火器筋板对，另外两个喷火器筋板195称为第二喷火器筋板对。第一喷火器筋板对共同形成第一喷火器通道，第二喷火器筋板对共同形成第二喷火器通道。第一喷火器筋板对设置在第一底杯筋板对上以共同形成一个内环一次空气补充部197(见图8)。第二喷火器筋板对设置在第二底杯筋板对上以共同形成另一个内环一次空气补充部197(见图9)。
该竖直文丘里管198位于该内环喷火器196中。该内火盖106盖设在该内环喷火器196上，该内火盖106、该内环喷火器196与竖直文丘里管198共同围成内混合气体到达腔室202。
具体地，内环喷火器196包括第一端204及与该第一端204相连的第二端206。该内火盖106盖设在该第一端204上。内环喷火器196沿其第一端204的周缘开设有内环火孔208。内环火孔208与内混合气体到达腔室202连通，空气与燃气在竖直文丘里管198里混合，混合后的混合气体进入内混合气体到达腔室202，混合气体再通过内环火孔208向外喷射形成内环火。
第二端206开设有内燃气抵达腔207。该竖直文丘里管198连通该内混合气体到达腔室202及该内燃气抵达腔207。该内环一次空气补充通道199与该内燃气抵达腔207相通。具体地，第二端206开设有喷火器开口209，使得内环一次空气补充通道199与该内燃气抵达腔207相通，空气由内环一次空气补充通道199经喷火器开口209向内燃气抵达腔207喷射，与由第二喷嘴喷射出来的燃气预混合，之后空气与燃气进入竖直文丘里管198再次进行混合，形成的混合气体从竖直文丘里管198向内混合气体到达腔室202喷射。
竖直文丘里管198包括进气端210及出气端212，进气端210位于内燃气抵达腔207且朝向第二喷嘴，出气端212位于内环喷火器196的第一端204中。内火盖106、内环喷火器196的第一端204与该出气端212共同围成内混合气体到达腔室202。
外环喷火器194设置在内环喷火器196***。该外火盖108盖设在该外环喷火器194上，该外火盖108与该外环喷火器194共同围成外混合气体到达腔室214，该外混合气体到达腔室214与该一次空气/燃气混合分配腔180连通。具体地，请结合图3，外环喷火器194开设有间隔的两个外环开口216，对应地，底杯盖114开设有间隔的两个 底杯盖开口218，外环开口216与底杯盖开口218配合连通，进而使该一次空气/燃气混合分配腔180与该外混合气体到达腔室214连通。
该外环喷火器194包括间隔设置外环部220及中环部222，该中环部222位于该内环喷火器196及该外环部220之间。外环开口216开设在外环部220与中环部222之间。该外环部220沿其周缘开设有与该外混合气体到达腔室214连通的外环火孔224，该中环部222可沿其周缘开设有与该外混合气体到达腔室214连通的中环火孔(图未示)。
在一次空气/燃气混合分配腔180里的混合气体经过底杯盖开口218及外环开口216进入外混合气体到达腔室214，然后从外环火孔224及中环火孔向外喷射分别形成外环火及中环火。因此，本实施方式的喷火器104可提供三环火，实现了外环火、中环火、内环火的多环高效燃烧器100。可以理解，如燃烧器100仅需要两环火时，可灵活设置，如在中环部222上不设置火孔即可。
进一步地，外环喷火器194还开设有引火槽226，引火槽226贯穿外环部220与中环部222。引火槽226与两个外环开口216沿外环喷火器194圆周依次分布。引火槽226用于将火焰从内环喷火器196引到外环喷火器194上。
连接筋200连接该内环喷火器196及该外环喷火器194。本实施方式中，连接筋200的数量为三个，三个连接筋200间隔地连接内环喷火器196及外环喷火器194，点火针及热电偶可分别穿设在相邻两连接筋200间的空间，并且点火针的一端与热电偶的一端靠近内环火孔208以实现点火。连接筋200实现了喷火器104的一体成型结构，进而提高喷火器104的装配、生产效率。
另外，为了喷火器104与底杯组件102的装配，该底杯盖114包括设置在该第一面119上的第一定位件230。该内环喷火器196的第二端206的端面设置有第二定位件232，该第一定位件230与该第二定位件232相互配合而将该喷火器104定位在该底杯盖114上。
具体地，本实施方式中，第一定位件230为设置在第一面119上的4个台阶结构，该4个台阶结构间隔地连接在凸筋158的外周缘。每个台阶结构包括第一顶面234及第二顶面236，第一顶面234较第二顶面236更靠近第二喷嘴。
第二定位件232为开设在第二端206的端面的4个定位凹槽，该4个定位凹槽的分布方式与4个台阶结构的分布方式相对应。安装时，例如，喷火器104放置于底杯盖114上，然后旋转喷火器104或底杯组件102，或同时旋转喷火器104及底杯组件102，使台阶结构卡进对应的定位凹槽中，定位凹槽的底面与台阶结构的第二顶面236相对准，进而定位喷火器104与底杯盖114的相对位置，限制了喷火器104的旋转方位。
进一步地，底杯盖114在底杯盖开口218的周缘设置有第一底杯盖配合面238，在 底杯补充部122两侧端设置有第二底杯盖配合面240。对应地，喷火器104在外环开口216的周缘设置有第一外环配合面242，在与底杯盖114相向的外环喷火器194表面设置有第二外环配合面244。喷火器104与底杯盖114安装好时，第一底杯盖配合面238与第一外环配合面242配合，第二底杯盖配合面240与第二外环配合面244配合，连同上述台阶结构/定位凹槽的定位结构一起可实现喷火器104和底杯组件102的全定位。另外，该底杯补充部122与该外环喷火器194之间形成有外环一次空气补充通道246(见图7及图9)，该外环一次空气补充通道246与该底杯一次空气补充室154连通。
进一步地，为了补充更多空气至中环火及内环火，请结合图3及图7，该外环喷火器194与该底杯盖114之间形成有间隙252，该喷火器104开设有位于该外环喷火器194与内环喷火器196之间的开口254。该间隙252与该开口254共同形成二次空气补充通道256。本实施方式中，该开口254即为相邻两连接筋200间的空间。
一部分二次空气可经由二次空气补充通道256进入到中环火孔和内环火孔208的火焰根部，另一部分二次空气是直接由外部提供到中环火孔和内环火孔208的火焰根部。而外环火的二次空气补充通道直接由外部提供到外环火孔224的火焰根部。
工作时，燃气经第一进气通道134的进气口140进入第一进气通道134，一部分燃气经第一喷嘴喷出至底杯一次空气补充腔172。第一喷嘴喷出的该部分燃气与经由外环一次空气补充通道246进入底杯一次空气补充腔172内的一次空气一起，进入水平文丘里管174内混合形成外环混合气体，外环混合气体到达一次空气/燃气混合分配腔180再经底杯盖开口218及外环开口216进入外环喷火器194并到达外混合气体到达腔室214，最后经由外环火孔224喷出形成外环火焰，和经由中环火孔(若有)喷出形成中环火焰。
另一部分燃气由连接通道138分流至第二进气通道136到达第二喷嘴，第二喷嘴喷出的该另一部分燃气至内燃气抵达腔207，该另一部分燃气与经由内环一次空气补充通道199进入的一次空气一起，进入竖直文丘里管198内再次混合，混合后的内环混合气体到达内混合气体到达腔室202，进入内环喷火器196，最后经由内环火孔208喷出形成内环火焰。
本实施方式中，所示的燃烧器100只有一个气源供气，即见图3所示，只有第一进气通道134的进气口140接气源，第二进气通道136的进气口(第二工艺孔150)用第二堵头封住，同时第一工艺孔146用第一堵头封住。如前所述，从气源中供出的燃气进入第一进气通道134的进气口140后一部分进入第一喷嘴给外环和/或中环供气，另一部分沿着连接通道138进入第二进气通道136后经由第二进气通道136与第二喷嘴连通给内环供气。可实现用一个气源同时供应多环火燃烧器100的目的。
当需要对多环火中的某一环单独实现火力控制的时候，比如在保持外环火力大小不变的同时需要单独调节内环火力的大小。这时需要单独提供另一气源给内环喷火器196，此时不加工连接通道138(横向进气通道)，仅需要移除第二堵头，将另一气源与第二进气通道136的进气口连通即可。
综上所述，上述燃烧器100中，供内环喷火器196的燃气可在内燃气抵达腔207与由内环一次空气补充通道199进入的空气进行混合，从而实现内环火燃气与一次空气的预混并能够充分燃烧，提高了内环喷火器196的燃气燃烧效率。
请参图10及图11，本发明较佳实施方式的燃气用具300包括以上实施方式的燃烧器100、锅支架302、灶具面板304及旋钮306。本实施方式中，燃气用具300为燃气灶。
锅支架302设置在灶具面板304上。灶具面板304开设有穿孔308及第二安装孔310，燃烧器100穿设穿孔308。燃烧器100的第一安装孔对准第二安装孔310，可利用固定件，如螺钉穿过第二安装孔310及第一安装孔而将燃烧器100固定在穿孔308中。第一进气通道134连接燃气用具的进气管312。
旋钮306设置在灶具面板304上，旋钮306用于控制燃烧器100的点火、关闭及燃气流量。
上述燃气用具300中，由于具有以上实施方式的燃烧器100，使供内环喷火器的燃气可在内燃气抵达腔与由一次空气补充通道进入的空气进行混合，从而实现内环火燃气与一次空气的预混并能够充分燃烧，提高了内环喷火器的燃气燃烧效率。
可以理解，在其它实施方式中，燃气用具可为大烤箱，该大烤箱包括以上实施方式的燃烧器100。
