具体实施方式
以下结合附图对本发明的实施方式作进一步说明。附图中相同或类似的标号自始至终表示相同或类似的元件或具有相同或类似功能的元件。
另外，下面结合附图描述的本发明的实施方式是示例性的，仅用于解释本发明的实施方式，而不能理解为对本发明的限制。
请参阅图1-图3，本发明实施方式提供的一种燃烧器100，包括底座10、第一分气结构20和第二分气结构40。
底座10内形成有燃气进气间12。底座10上设置有燃气进气通道14。燃气进气通道14连通燃气进气间12。
第一分气结构20包括第一导气管22和第一腔体24。第一导气管22连接第一腔体24。第一腔体24间隔设置在底座10上以形成一次空气补充通道30。一次空气补充通道30与燃气进气间12连通。第一腔体24开设有第一腔室242。第一导气管22连通第一腔室242和燃气进气间12。第一导气管22伸入燃气进气间12内。
第二分气结构40包括第二腔体42和第三腔体44。第二腔体42的底面 间隔设置有第二导气管422和第三导气管424，第二导气管422和第三导气管424伸进燃气进气间12内。第二腔体42开设有第二腔室426。第二导气管422连通第二腔室426和燃气进气间12。第三腔体44设置在第二腔室426中。第三腔体44开设有与第二腔室426间隔的第三腔室442。第三导气管424连通第三腔室442和燃气进气间12。
本发明实施方式的燃烧器100中，三个腔室的结构可实现三环火的燃烧器100。底座10与第一腔体24间形成的一次空气补充通道30可吸入更多的一次空气进入燃气进气间12，保证第一腔室242、第二腔室426和第三腔室442的混合气体中的一次空气的含量充足，使燃气燃烧更充分，燃烧器100的火力更大。
具体地，底座10的外侧面16呈圆形，设置在底座10上的燃气进气间12呈方形。
如此，底座10外圆内方的结构，使得喷射出来的燃气产生的压力更大，进而经一次空气补充通道30引入更多空气进入燃气进气间12，使得燃气的燃烧更完全，提高燃气燃烧的效率。
具体地，本发明实施方式中的第一腔室242相当于燃烧器100的外环燃气腔室，第一腔室242上设置有外环火盖248；第二腔室426相当于中环燃气腔室，第二腔室426上设置有中环火盖428；第三腔室442相当于内环燃气腔室，第三腔室442上设置有内环火盖446。在本发明实施方式中，设置在第三腔室442上的内环火盖446为多孔陶瓷板。
如此，燃气在多孔陶瓷板上燃烧，使多孔陶瓷板变红，形成红外线煮食，实现了极小火、炭火慢炖等功能。同时，气体在第二腔室426上的中环火盖428处燃烧形成蓝色的中环火焰，从而巧妙地实现红蓝组合燃烧火焰，提高了燃烧性能和加热效率。
在某些实施方式中，底座10上设置有接液盘60。底座10和接液盘60间隔设置形成一次空气补充通道30。
如此，接液盘60作为空气进入一次空气补充通道30的承接部，使得空气流动更顺畅。同时，接液盘60还能盛接燃烧器100使用过程中溢出的汤汁，避免汤汁流进燃烧器100内部，保持燃烧器100的清洁，接液盘60还能实现一抹净的效果，减少了用户清洁燃烧器100的麻烦。
在某些实施方式中，接液盘60和底座10上表面上的凸起18配合，紧密安装在底座10上。接液盘60的上表面低于凸起18的顶端。
如此，凸起18可防止溢出的汤汁沿接液盘60回流到燃烧器100内部，进一步保证燃烧器100的清洁。
进一步地，接液盘60覆盖底座10。
如此，可保证溢出的汤汁流出到燃烧器100外部且不会残留在底座10附近，造成用户难以清洁的情况。
请一并参阅图5和图7，在某些实施方式中，第一导气管22的管口形成多个豁口222。第一导气管22伸入燃气进气间12内且第一导气管22位于一次空气补充通道30下方。
如此，多个豁口222能增加空气进入第一导气管22的路径，使得空气和燃气进行充分地混合，提高了燃气燃烧的效率。
具体地，豁口222呈光滑圆弧状。
如此，增加了空气进入第一导气管22的速度，便于将空气导入第一导气管22。
每个第一导气管22上的豁口222的数量为4个。
如此，能较好地实现导入空气补充的目的。
当然，豁口222的数量不限于上述讨论的实施方式，而可以根据第一导气管22的管径大小设置不同数量的豁口222以保证空气更迅速地进入第一导气管22。
在某些实施方式中，第三腔室442的内壁上设置有阶梯状的安装部4423。安装部4423用于安装内环火盖446。
如此，内环火盖446能较稳定地安装在燃烧器100上，不会出现左右和向下的位移，以便燃烧器100内的燃气在内环火盖446处形成稳定的火焰。同时阶梯状的安装部4423还能防止燃烧器100内的燃气从安装部4423和第三腔体44之间的缝隙泄露，影响加热效果。
在某些实施方式中，燃气进气通道14呈十字型设置在底座10的底部，燃气进气通道14包括多个出气口142，每个出气口142设置有一个喷嘴144，每个喷嘴144对应一个导气管。
如此，设置有多个出气口142的燃气进气通道14优化了通气管路，增强了燃气的进气性能。还可根据不同的情况堵住部分燃气进气通道14，调节燃气的进气量，减少燃气的浪费，节约能源。喷嘴144则加速了燃气进入燃气进气间12的速度，从而使燃气的燃烧更加稳定。本发明实施方式中，喷嘴144的数量为4个。在本实施方式中，第一导气管22的数量为两个，喷嘴144的数量为4个，每个喷嘴144对应一个导气管，也就是说，第一导气管22对应有两个喷嘴144，第二导气管422对应有一个喷嘴144，第三导气管424对应有一个喷嘴144。
在某些实施方式中，第一腔体24包括间隔的分气盘244和连接盘246，连接盘246设置在底座10上并与底座10间隔以形成一次空气补充通道30，分气盘244设置在连接盘246上并与连接盘246间隔形成二次空气补充通道50，第二腔体42穿设分气盘244并承载在连接盘246上。
如此，一次空气补充通道30和二次空气补充通道50采用错层结构，可使一次空气补充通道30和二次空气补充通道50设计成较大尺寸而相互不影响，燃烧器100可在燃气燃烧时补充大量空气，使得燃气的燃烧更完全，避免了燃气燃烧不彻底而造成的安全隐患和环境污染。
在某些实施方式中，分气盘244和连接盘246均呈圆形，且分气盘244在连接盘246上的正投影位于连接盘246上。
如此，燃烧器100使用过程中溢出的汤汁沿连接盘246流出，不会进入 燃烧器100内部，减少了用户清洁燃烧器100的麻烦，也避免了溢出的汤汁进入燃烧器100内部锈蚀燃烧器100，减少燃烧器100的寿命。
具体地，分气盘244和连接盘246通过连接部241连接。在本发明示例中，连接部241的数量为多个，多个连接部241间隔设置。
如此，分气盘244和连接盘246之间的连接更加稳定，燃烧器100遇到轻微碰撞或跌落时，分气盘244和连接盘246不会分离，保证了燃烧器100的使用寿命。
在本发明示例中，两个第一导气管22穿设其中的两个连接部241。
如此，可避免第一导气管22占用二次空气补充通道50的进口的面积，保证二次空气补充通道50的进气量。
在某些实施方式中，一次空气补充通道30沿燃烧器100的周向连续分布。
如此，实现空气从燃烧器100的360度方位进入燃气进气间12，极大地提高了一次空气的进气量。
具体地，一次空气补充通道30沿燃烧器100的周向连续分布使得燃气进气间12各个方位上没有遮挡，燃烧器100各个方位的空气均能通过一次空气补充通道30进入燃气进气间12。
在某些实施方式中，二次空气补充通道50的进口沿燃烧器100的周向连续分布。
如此，实现空气从燃烧器100的360度方位进入第一腔体24，极大地提高了二次空气的进气量。同时，二次空气补充通道50和一次空气补充通道30错层分布，二者不会相互影响，完善了燃烧器100的空气补充效果。
在某些实施方式中，分气盘244的中间位置开设有方形通孔2442，分气盘244的外侧面2444呈圆形，第二腔体42穿设方形通孔2442。
如此，分气盘244呈外圆内方的结构，使得第二腔体42安装到方形通孔2442内后，第二腔体42和方形通孔2442之间形成较大空隙，供二次空 气补充通道50补充的空气进入，为燃气进行空气补充，提高燃气的燃烧效率。
进一步地，第二腔体42呈圆形时，分气盘244的中间也可开设其他形状的孔，比如圆形孔(图未示)。圆形孔的直径大于第二腔体42的直径。
如此，便于二次空气补充通道50进入的空气对燃气进行空气补充。
在某些实施方式中，第二腔体42的外壁上设置有定位部423。方形通孔2442的边缘形成有凸缘24422，定位部423与凸缘24422配合连接而将第二分气结构40可拆卸地定位在方形通孔2442中。
在某些实施方式中，定位部423包括导引部4232和承靠部4234，导引部4232连接承靠部4234，导引部4232用于导引第二分气结构40的安装，导引部4232凸出第二腔体42的外壁，且导引部4232凸出的高度由下到上逐渐增加。承靠部4234开设有与凸缘24422形状相匹配的槽位，承靠部4234通过槽位承靠在凸缘24422上。
在本发明实施方式中，第二腔体42相背两侧的每一侧都设置有间隔的两个定位部423。如此，第二分气结构40的安装较稳固，避免第二分气结构40在燃烧器100中的移位。
另外，本发明实施方式中，底座10的上表面设置有凸起18，凸起18和连接盘246的下表面间隔设置。
如此，既不会影响空气从一次空气补充通道30进入燃烧器100，又能防止燃气进气间12内的燃气从一次空气补充通道30泄露。
请参阅图4，在某些实施方式中，连接盘246的下表面的边缘向底座10方向弯曲形成檐状结构2462。
如此，檐状结构2462能进一步防止燃气进气间12内的燃气泄露，保证了燃烧器100使用的安全性。同时，溢出的汤汁能沿檐状结构2462流到燃烧器100外部，保证了燃烧器100的清洁。
在某些实施方式中，分气盘244的下表面边缘和连接盘246的上表面边 缘共同形成沿二次空气补充通道50进气方向渐缩的结构。
如此，二次空气补充通道50的进口形成沿气流方向渐缩的结构，更易于空气进入，进一步加强了空气补充，提高了燃气燃烧的效率。
在某些实施方式中，第一腔室242中设置有两个隔断件2422，两个隔断件2422将第一腔室242隔开为两个子燃气腔室2424，第一导气管22的数量为两个，其中一个子燃气腔室2424通过其中一个第一导气管22与燃气进气间12连通，另一个子燃气腔室2424通过另一个第一导气管22与燃气进气间12连通。
如此，两个子燃气腔室2424内的燃气分布相较于第一腔室242整体相通时更加均匀，从而使得燃气在设置在第一腔室242上的外环火盖248处燃烧更加均匀。
具体地，在本发明示例中，每个子燃气腔室2424开设有第一腔室进气孔2426，腔室进气孔2426位于子燃气腔室2424的中间位置。在一个例子中，每个子燃气腔室2424基本呈180度的圆弧状，腔室进气孔2426位于子燃气腔室2424内90度的位置。如此，每个子燃气腔室2424使燃气在第一腔室242内更迅速地达到均匀分布的状态。
另外，在某些实施方式中，隔断件2422并不完全隔断两个子燃气腔室2424，相较于没有隔断件2422，两个子燃气腔室2424在隔断件2422处仍然有小面积的相通。
如此，能防止部分第一导气管22出现堵塞时，第一腔室242内仍能保持充足燃气供应。
在某些实施方式中，隔断件2422呈直角梯形。隔断件2422的顶端和斜边和外环火盖248间隔设置。
如此，既实现了隔开第一腔室242的目的，使得第一腔室242内的燃气分布更均匀，又不会完全将两个子燃气腔室2424独立开来。
进一步地，外环火盖248的外侧面开设有火孔。在某些实施方式中，外 环火盖248的外侧面和内侧面均开设有火孔。
请参阅图8-图10，在某些实施方式中，第二导气管422在第二腔室426的底面形成第一开口4262，第三导气管424在第二腔室426的底面形成与第一开口4262间隔的第二开口4264；
第三腔室442的底面4421开设有与第三腔室442相通的通气孔4422，通气孔4422与第二开口4264连通；
第三腔体44的底面间隔覆盖在第一开口4262的上方且设置有隔开第一开口4262与第二开口4264的挡壁444。
如此，由第二导气管422出射的气体由第三腔体44的底面分散到第二腔室426的各个位置后向上扩散。如此，使得第二腔体42较均匀地向第二腔室426的各个位置供气，保证第二腔体42所形成的火焰均匀。同时，挡壁444可使第二腔室426和第三腔室442的供气相互不影响。
具体地，本发明实施方式中，第二腔体42和第三腔体44基本呈圆柱状。
如此，结构简单，易于制造。同时，便于气体进入第二腔室426和第三腔室442时更流畅，保证气体的流速，从而保证燃气在第二腔室426上的中环火盖428处和第三腔室442上的内环火盖446处燃烧的稳定性。
在本发明实施方式中，第三腔体44的侧壁上设置有承放部443，承放部443用于在安装第三腔体44时使第三腔体44放置更稳定。
在一个例子中，第二腔体42和第三腔体44可采用铜制成。
如此，第二腔体42和第三腔体44能耐高温，延长燃烧器100的使用寿命。同时，使得第二腔体42和第三腔体44易于铸造成型，形成第一开口4262、第二开口4264和通气孔4422等结构，实现较佳的分气作用。
在某些实施方式中，挡壁444呈环形并向远离第三腔体44的方向凸出，通气孔4422贯穿挡壁444。
如此，增加了通气孔4422的长度，使得更多的气体能被收集进入到第三腔室442内，保证第三腔室442的供气量。
当然，挡壁444突出第三腔体44的底面的距离可随第三腔室442的大小进行调整以使第三腔室442的供气量和气体速度更加优化。
请参阅图11-图13，在某些实施方式中，第二腔室426的底面上开设有凹槽4266，凹槽4266围绕第二开口4264，凹槽4266和挡壁444配合连接以隔开第一开口4262与第二开口4264。
如此，第二腔体42和第三腔体44之间连接紧密，第一开口4262和第二开口4264被完全隔断，燃烧器100的分气性能得到大幅提升，避免了燃烧器100在高温环境中使用时间较长后，第二腔体42和第三腔体44发生形变导致连接不紧密从而影响燃烧器100的分气性能的情况。
具体地，挡壁444***凹槽4266中。
如此，燃烧器100在高温环境中工作时，挡壁444受热膨胀，使得挡壁444与凹槽4266的结合更加紧密，能较佳地阻止气体在第二腔室426和第三腔室442之间发生流通，保证了燃烧器100的分气效果。
在某些实施方式中，通气孔4422的孔壁包括导流面4424，通气孔4422中设置有遮挡片4426，遮挡片4426和导流面4424相对间隔设置并与导流面4424共同形成用于导引气体进入第三腔室442的导流通道4428。
如此，气体沿导流通道4428进入第三腔室442，大大提高了气体进入第三腔室442的气流速度和流畅度，使得气体在燃烧器100外的燃烧更稳定。
具体地，燃烧器100使用时，燃气与空气形成的混合气体喷向遮挡片4426形成气流，遮挡片4426将混合气体的方向转向导流通道4428，混合气体经导流通道4428进入第三腔室442内。
在某些实施方式中，导流通道4428沿通气孔4422的进气方向呈渐扩的形状。
如此，有助于气体更顺畅地通过导流通道4428进入第三腔室442，同时也增加了气体的流速，保证燃气在内环火盖446处燃烧更稳定。
在某些实施方式中，导流面4424呈弧形，遮挡片4426包括顶面44262、 底面44264和连接面44266，顶面44262和底面44264为平面，连接面44266连接顶面44262和底面44264，连接面44266呈弧形且与导流面4424形成导流通道4428。
如此，气体沿导流通道4428进入第三腔室442时，弧形的导流面4424能使气体受到的阻力减少，进而达到更快的速度。同时，弧形的导流面4424使得气体流动更加平稳，避免了气体进入第三腔室442内后形成紊流或湍流，而出现影响燃气燃烧稳定性的情况。
在某些实施方式中，导流面4424和第三腔室442的底面4421的连接处为圆滑曲面。
如此，增加气体进入第三腔室442内的流畅性。
进一步地，导流面4424还可设置为斜面。
如此，也能实现协助燃气顺畅进入第三腔室442内的目的。
较佳地，导流面4424为斜面时，导流面4424和第三腔室442的底面4421形成的锐角为45度。
如此，能进一步优化气体进入第三腔室442内的速度。
弧形的连接面44266则使气体冲击第三腔体44的底面底部后，被直接转向，减少了气体的速度损失。连接面44266配合导流面4424，形成供气体顺畅进入第三腔室442的导流通道4428。
进一步地，本发明实施方式中连接面44266和导流面4424之间的距离为0.5厘米-1.5厘米。
如此，气体经遮挡片4426转向分散后通过导流通道4428时，由于气流通道变窄，气体发生挤压，流速增加。同时，气体在导流通道4428下方形成负压，吸取更多气体进入导流通道4428，进一步增加了气体的流速。
在某些实施方式中，第三腔室442的底面4421和遮挡片4426的顶面44262处于同一平面。
如此，使得气体从通气孔4422进入第三腔室442后气体流动平稳、迅 速，避免出现顶面44262和第三腔室442的底面4421不在同一平面时气体进入第三腔室442后形成紊流的现象，进一步保证燃气从第三腔室442喷射后燃烧稳定。
在某些实施方式中，同一平面是指同一水平面。
在某些实施方式中，遮挡片4426包括与通气孔4422的孔壁连接的遮挡片连接部44268，遮挡片连接部44268上开设有多个通孔44261，多个通孔44261连通通气孔4422和第三腔室442。
由于遮挡片4426转向气体时，有小部分的气体被转向至遮挡片连接部44268的方向，开设通孔44261能够将这部分气体导入到第三腔室442中，避免了气体流失，增加了第三腔室442的供气量。
具体地，本发明实施方式中，通孔44261有4个，且均匀设置在连接部241上。
如此，提高了通孔44261分流的效果。
当然，通孔44261的个数不限于上述讨论的实施方式中的个数，而可以根据气体流量的大小和第三腔室442的大小进行调整，以达到较佳的分气效果。
在某些实施方式中，第三腔体44还包括固定部448，固定部448连接遮挡片4426和第三腔室442的底面4421。
由于燃烧器100在高温环境下工作，遮挡片4426容易发生形变，影响燃烧器100的分气效果。固定部448进一步加固了遮挡片4426，保证了遮挡片4426稳定设置在第三腔体44上，不易发生形变，进而达到较佳的分气效果，提高了燃烧器100的可靠度。
在某些实施方式中，第三腔体44可拆卸地安装在第二腔室426中。
如此，易于将第三腔体44拆卸下来对第二腔体42和第三腔体44进行清洁，保持燃烧器100的清洁。
在某些实施方式中，第三腔体44除了通过挡壁444和第二腔室426的 底面上的凹槽4266配合来安装在第二腔体42中，还能通过在第三腔体44上设置定位件441，在第二腔室426的底面上开设定位孔421，通过定位件441和定位孔421的配合将第二腔体42安装到第三腔体44中。
如此，第三腔体44能稳定安装在第二腔体42中。第二腔体42和第三腔体44之间不易发生相对滑落，从而保证燃烧器100的分气性能。同时，也便于第三腔体44的安装和拆卸。
具体地，定位件441有4个，呈长方形的四个顶点分布在第三腔体44的底面上。
请参阅图4，本发明实施方式的燃烧器100工作时，燃气从燃气进气通道14输入，通过设置在燃气进气通道14上的喷嘴144喷入燃气进气间12，喷入的燃气在燃气进气间12产生负压以从一次空气补充通道30吸入一次空气A，如图4所示，一次空气与燃气在燃气进气间12预混形成混合气体。一部分混合气体经第一导气管22的导引进入第一腔室242，如A1所示，经外环火盖248向外喷射、燃烧形成外环火。
在燃气进气间12内的燃气与空气的另一部分混合气体(如图4中线路A2所示)经第二导气管422和第三导气管424的导引分别进入第二腔室426和第三腔室442，第二腔室426的混合气体经中环火盖428向外喷射，燃烧形成中环火。进入第二腔室426的混合气体的流动方向可参虚线A21所示。
第三腔室442中的混合气体经内环火盖446向外喷射，燃烧形成红外线的内环火。进入第三腔室442的混合气体的流动方向可参虚线A22所示。
二次空气补充通道50可对中环火盖428和内环火盖446处的燃气燃烧补充二次空气，和/或对外环火盖248内侧的燃气燃烧时补充二次空气，二次空气经二次空气补充通道50进入燃烧器100内部并向上流动，进而实现补充二次空气。二次空气进入燃烧器100的气体的流动方向如图中带箭头的虚线B所示。
如此，燃烧器100通过第一导气管22、第二导气管422和第三导气管 424分气，实现了三环火的燃烧器100，提高了燃烧器100的加热效率。
本发明实施方式的燃气灶具包括如上任一实施方式的燃烧器100。
本发明实施方式的燃气灶具中，三个腔室的结构可实现三环火的燃气灶具。底座10与第一腔体24间形成的一次空气补充通道30可吸入更多的一次空气进入燃气进气间12，保证第一腔室242、第二腔室426和第三腔室442的混合气体中的一次空气的含量充足，使燃气燃烧更充分，燃气灶具的火力更大。
