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110及第二喷嘴112。
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。具体地，请结合图5及图8，该底杯盖114包括进气口组件120、第一补充部122、第一混合部124及第二补充部126。
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、该第一补充部122及该第一混合部124依次连接。该第二补充部126连接在该第一混合部124的上方，该第二进气部130穿设该第一补充部122及该第二补充部126，该连接部132设置在该第一补充部122的外侧壁。
请结合图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8，第二进气部130为呈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8，该第二进气部130开设有第二进气通道136。请结合图11，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。
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。
见图7，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110设置在该第一进气通道134的出气口142。第二进气通道136具有出气口144(见图4及图8)，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112设置在该第二进气通道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110喷射至第一补充部122，另一部分燃气通过第二喷嘴112喷射至第二补充部126。
见图8、图11，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4)。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148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4)，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152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152，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。
见图5，图7，该第一补充部122呈扇形，第二进气部130穿设在第一补充部122的内侧边。第一补充部122开设有第一一次空气补充室154。第一一次空气补充室154贯穿第一补充部122。该第一一次空气补充室154通过第一喷嘴110与第一进气通道134连通。第一进气部128连接在第一补充部122的较大端，第一混合部124连接在第一补充部122的较小端。气流从第一补充部122的较大端方向流向第一补充部122的较小端方向，这有利于气流的喷射。
该第二补充部126开设有第二一次空气补充室156。该第一一次空气补充室154与该第二一次空气补充室156互相分隔。第二喷嘴112及远离连接部132的第二进气部130的一端位于第二一次空气补充室156。第二一次空气补充室156通过第二喷嘴112与第二进气通道136连通。
底杯盖114还包括设置在该第二一次空气补充室156周缘的凸筋158，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110、112的隐患。
该第一混合部124开设有与该第一一次空气补充室154连通的第一凹槽162(见图5)，第一凹槽162与该第二一次空气补充室156互相分隔。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110 与第一凹槽162直通，第一凹槽162的后端(远离第一喷嘴110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110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与该第一补充部122连接且开设有第一腔室170，该第一腔室170与该第一一次空气补充室154共同形成第一一次空气补充腔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。
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与该第一一次空气补充腔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10及图11，一次空气/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。
见图1及图4，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。
底杯组件102上还安装有点火装置184。具体地，点火装置184包括点火针186及热电偶188，底杯座116开设有供点火针186及热电偶188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。热电偶188依次穿设第一过孔190及第二过孔192，点火针186依次穿设第一过孔190及第二过孔192。
见图2，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包括外环喷火器194、内环喷火器196、竖直文丘里管198及连接筋200。
见图7，该内环喷火器196位于该外环喷火器194中，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。该竖直文丘里管198连通该内混合气体到达腔室202及该第二一次空气补充室156。由于第一一次空气补充室154与第二一次空气补充室156互相分隔，因此，竖直文丘里管198与水平文丘里管174可独立地工作，避免相互之间的影响。
具体地，见图8，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。
见图7，竖直文丘里管198包括进气端210及出气端212，进气端210朝向第二一次空气补充室156，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。
见图7及图9，外环喷火器194设置在内环喷火器196外围。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4及图9，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。
见图2，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。
见图2，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186及热电偶188分别穿设在相邻两连接筋200间的空间，并且点火针186的一端与热电偶188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，如图3，为了喷火器104与底杯组件102的装配，该底杯盖114包括朝向该喷火器104的第一面228及设置在该第一面228上的第一定位件230。如图5，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228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更靠近第二一次空气补充室156。
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或底杯盖114，或同时旋转喷火器104及底杯盖114，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。
见图3，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，在第一补充部122两侧端设置有第二底杯盖配合面240。对应地，见图5，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，该第一补充部122与该外环喷火器194之间形成有第一一次空气补充通道246(见图7)，该第一一次空气补充通道246与该第一一次空气补充室154连通。该第二端206的端面与该第一面228之间形成有第二一次空气补充通道248(见图8)，该第二一次空气补充通道248与该第二一次空气补充室156连通。
见图2，该连接筋200还开设有可视窗250，该可视窗250连通其中一个定位凹槽，这使得用户可以方便地通过可视窗250看得见，台阶结构是否卡进定位凹槽，以完成喷火器104在底杯组件102上的装配。
进一步地，为了补充更多空气至中环火及内环火，请结合图2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。
见图7及图9，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110喷出至第一一次空气补充腔172。第一喷嘴110喷出的该部分燃气与经由第一一次空气补充通道246进入第一一次空气补充腔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(外环一次空气/燃气混合分配腔)再经底杯盖开口218及外环开口216进入外环喷火器194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，和经由中环火孔喷出形成中环火焰。
见图8，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112，第二喷嘴112喷出的该另一部分燃气与经由第二一次空气补充通道248(内环一次空气补充通道)进入第二一次空气补充室156(内环一次空气补充室)内的一次空气一起，进入竖直文丘里管198内混合，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11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152封住，同时第一工艺孔146用第一堵头148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110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112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152，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即可适应单进气源供气，又可适应双进气源供气，以满足不同的消费者使用需求，提高产品的通用化、标准化程度。
请参图12及图13，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，即可适应单进气源供气，又可适应双进气源供气，以满足不同的消费者使用需求，提高产品的通用化、标准化程度。
可以理解，在其它实施方式中，燃气用具可为大烤箱等其它燃气用具，该大烤箱包括以上实施方式的燃烧器100。
