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和第一分气盘结构20。底座10开设有燃气进气间12。第一分气盘结构20设置在底座10上，第一分气盘结构20包括间隔的分气盘22和连接盘24，连接盘24设置在底座10上并与底座10间隔以形成第一空气补充通道26，第一空气补充通道26与燃气进气间12相通，分气盘22设置在连接盘24上并与连接盘24间隔形成第二空气补充通道28。
本发明实施方式中的燃烧器100，第一空气补充通道26和第二空气补充通道28采用错层结构，可使第一空气补充通道26和第二空气补充通道 28设计成较大尺寸而相互不影响，如此，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。
请一并参阅图8，具体地，底座10和第一分气盘结构20相背的一侧设置有多个燃气进气通道14，燃气进气通道14在燃气进气间12的一面上开设有多个燃气喷口16。燃气喷口16上安装有喷嘴18。
如此，多个燃气进气通道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18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18的数量为4个。
本发明实施方式中，第一空气补充通道26作为燃烧器100的一次空气补充通道，第二空气补充通道28作为燃烧器100的二次空气补充通道。
在某些实施方式中，请结合图8，底座10的外侧面13呈圆形，燃气进气间12呈方形。
如此，外圆内方的结构，使得喷嘴18喷射出来的燃气产生的压力更大，进而经第一空气补充通道26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。
请参阅图5-图7，在本发明实施方式中，分气盘22和连接盘24均呈圆形，且分气盘22在连接盘24上的正投影位于连接盘24上。
如此，燃烧器100使用过程中溢出的汤汁沿连接盘24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。
在本发明实施方式中，分气盘22和连接盘24通过连接部23连接。在本发明示例中，连接部23的数量为多个，多个连接部23间隔设置。
如此，分气盘22和连接盘24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22和连接盘24不会分离，保证了燃烧器100的使 用寿命。
在某些实施方式中，第一空气补充通道26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，第一空气补充通道26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第一空气补充通道26进入燃气进气间12。
另外，本发明实施方式中，底座10的上表面设置有凸起11，凸起11和连接盘24的下表面间隔设置。
如此，既不会影响空气从第一空气补充通道26进入燃烧器100，又能防止燃气进气间12内的燃气从第一空气补充通道26泄露。
进一步地，在某些实施方式中，连接盘24的下表面的边缘向底座10方向弯曲形成檐状结构242。
如此，檐状结构242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242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，第二空气补充通道28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度方位进入第一分气盘结构20，极大地提高了二次空气的进气量。同时，第二空气补充通道28和第一空气补充通道26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。
进一步地，在某些实施方式中，分气盘22的下表面边缘和连接盘24的上表面边缘共同形成沿第二空气补充通道28进气方向渐缩的结构。
如此，第二空气补充通道28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，第一分气盘结构20包括第一导气管21，第一导气管21穿设分气盘22和连接盘24并伸进燃气进气间12。
如此，第一导气管21伸进燃气进气间12可使燃气进气间12内的空气与燃气的混合气体能够直接进入第一导气管21，并从第一导气管21输向分气盘22，避免了燃气和空气的混合气体从燃气进气间12泄露的情况，保证了燃烧器100的使用安全。
具体地，在本发明实施方式中，经喷嘴18进入的燃气与经第一空气补充通道26进入的空气在燃气进气间12里进行预混，燃气喷射出来时，会带动空气一起进入第一导气管21内并进一步混合形成混合比例均匀的混合气体。
本发明实施方式中，第一导气管21的数量为2个，并分别设置在分气盘22的两侧。
如此，保证了对分气盘22的燃气的充足供应，进而保证了燃烧器100的火力，同时，两个第一导气管21占用的第二空气补充通道28的体积较少，不会影响第二空气补充通道28的空气补充效果。
在某些实施方式中，第一导气管21为文丘里管结构。
进一步地，第一导气管21的外壁和分气盘22以及连接盘24的外边缘间隔设置。如此，第一导气管21不会影响到第二空气补充通道28的进口的周向连续性，进一步保证了第二空气补充通道28的空气补充量。
在本发明示例中，两个第一导气管21穿设其中的两个连接部23，如此，可避免第一导气管21占用第二空气补充通道28的进口的面积，保证第二空气补充通道28的进气量。
在某些实施方式中，第一导气管21的管口形成多个豁口212。
由于第一导气管21伸入了燃气进气间12且第一导气管21位于第一空气补充通道26下方，多个豁口212能增加空气进入第一导气管21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212呈光滑圆弧状。
如此，增加了空气进入第一导气管21的速度，便于将空气导入第一导气管21。
每个第一导气管21上豁口212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212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21的管径大小设置不同数量的豁口212以保证空气更迅速地进入第一导气管21。
在某些实施方式中，请参图5和图7，分气盘22开设有燃气腔室222，分气盘22包括两个隔断件224，两个隔断件224将燃气腔室222隔开为两个子燃气腔室2214，每个子燃气腔室2214与燃气进气间12连通。
如此，两个子燃气腔室2214内的燃气分布相较于燃气腔室222整体相通时更加均匀，从而使得燃气在设置在燃气腔室222上的火盖处燃烧更加均匀。
具体地，在本发明示例中，每个子燃气腔室2214开设有进气孔2216，进气孔2216位于子燃气腔室2214的中间位置。在一个例子中，每个子燃气腔室2214基本呈180度的圆弧状，进气孔2216位于子燃气腔室2214上90度的位置。如此，每个子燃气腔室2214使燃气在燃气腔室222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224并不完全隔断两个子燃气腔室2214，相较于没有隔断件224，两个子燃气腔室2214在隔断件224处仍然有小面积的相通。
如此，能防止部分第一导气管21出现堵塞时，燃气腔室222内仍能保持充足燃气供应。
进一步地，隔断件224呈直角梯形。隔断件224的顶端和斜边和火盖 228间隔设置。
如此，既实现了隔开燃气腔室222的目的，使得燃气腔室222内的燃气分布更均匀，又不会完全将两个子燃气腔室2214独立开来。
在本发明实施方式中，分气盘22的燃气腔室222相当于外环燃气腔室。
另外，在本发明实施方式中，分气盘22上设置有火盖228，火盖228的外侧面开设有火孔。在某些实施方式中，火盖228的外侧面和内侧面均开设有火孔。
在某些实施方式中，分气盘22的中间位置开设有方形通孔226，分气盘外侧面221呈圆形。
如此，分气盘22呈外圆内方的结构，使得第二分气盘结构30安装到方形通孔226内后，第二分气盘结构30和方形通孔226之间形成较大空隙，供第二空气补充通道28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，分气盘22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分气盘结构30的直径。
如此，便于第二空气补充通道28进入的空气对燃气进行空气补充。
请一并参阅图2、图3和图9，在某些实施方式中，燃烧器100包括第二分气盘结构30，第二分气盘结构30穿设方形通孔226并承载在连接盘24上，第二分气盘结构30包括第二导气管32，第二导气管32穿设连接盘24并伸进燃气进气间12。
如此，由第一空气补充通道26进入燃气进气间12的空气可由伸入燃气进气间12的第二导气管32混合燃气，进入设置在第二分气盘结构30的燃气腔室。使得燃气的燃烧更充分。
具体地，在一个例子中，第二导气管32的数量为2个。
如此，保证了进入设置在第二分气盘结构30的燃气腔室的燃气量，同时，燃气由燃气进气间12进入第二导气管32时路径变窄，燃气的流速增加， 也进一步提高了燃气燃烧的稳定性。
进一步地，两个第二导气管32可分别导向第二分气盘结构30的不同燃气腔室，例如，在某些实施方式中，第二分气盘结构30的燃气腔室包括内环燃气腔室和中环燃气腔室，一个第二导气管32将混合气体导入内环燃气腔室，另一个第二导气管32将混合气体导入中环燃气腔室。
如此，可进一步实现分气作用，实现三环火的燃烧器100，更有效地利用燃气，提高燃烧器100的加热效率。在某些实施方式中，内环燃气腔室可设置多孔陶瓷板，以红外煮食实现极小火、炭火慢炖等功能。
请参阅图3，在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，例如通过其中两个喷嘴18喷入燃气进气间12，喷入的燃气在燃气进气间12产生负压以从第一空气补充通道26吸入一次空气，一次空气与燃气在燃气进气间12预混，并共同经过连接盘24进入分气盘22。例如，经第一导气管21的导引进入分气盘22的燃气腔室222，分气盘22内的空气与燃气的混合气体出外喷射，经火盖228向外喷射、燃烧形成外环火。进入分气盘22的气体的流动方向如图3中带箭头的虚线a所示。在一个例子中，请参图8，向分气盘22输送燃气的两个喷嘴18是沿同一直线排列且相距较远的两个喷嘴18。
在燃气进气间12内的燃气与空气的混合气体可经第二导气管32的导引进入第二分气盘结构30，并从第二分气盘结构30上的火盖向外喷射，燃烧形成内环火和/或中环火。在一个例子中，请参图8，向第二分气盘结构30输送燃气的两个喷嘴18是沿同一直线排列且相距较近的两个喷嘴18。进入第二分气盘结构30的气体的流动方向可参虚线b所示，形成内环火和/或中环火的气体流动方向如图3中带箭头的虚线b1和b2所示。
第二空气补充通道28可对第二分气盘结构30的燃气燃烧时补充二次空气，和/或对分气盘22上的火盖228内侧的燃气燃烧时补充二次空气，二次空气经第二空气补充通道28进入燃烧器100内部并向上流动，进而补充二 次空气。二次空气进入燃烧器100的气体的流动方向如图3中带箭头的虚线c所示。
在某些实施方式中，第二分气盘结构30的外壁上设置有定位部34，方形通孔226的边缘形成有凸缘2262，定位部34与凸缘2262配合连接而将第二分气盘结构30可拆卸地定位在方形通孔226中。
如此，结构简单，易于第二分气盘结构30安装和拆卸。同时，第二分气盘结构30能稳定地设置在方形通孔226中，燃烧器100遇到轻微碰撞和跌落时，第二分气盘结构30不易从方形通孔226中脱落，延长了燃烧器100的使用寿命。
具体地，在本发明实施方式中，定位部34包括导引部342和承靠部344，导引部342连接承靠部344，导引部342用于导引第二分气盘结构30的安装，导引部342凸出第二分气盘结构30的外壁，且其高度由下到上逐渐增加。承靠部344开设有与凸缘2262形状相匹配的槽位，承靠部344通过槽位承靠在凸缘2262上。
在本发明实施方式中，第二分气盘结构30的相背两侧的每一侧都设置有间隔的两个定位部34。
在某些实施方式中，第二导气管32为文丘里管结构。
如此，燃气和空气的混合气体流经第二导气管32时，混合更均匀且流速增加，进一步保证了燃气燃烧的稳定性。
具体地，燃气和空气形成的混合气体从第二导气管32的入口进入，随着第二导气管32的截面减小，混合气体的压强增大，流速也随之变大，在第二导气管32的进口处产生一个真空度，致使第二导气管32周围的混合气体被吸入第二导气管32内，使得混合气体的流速进一步增加。
在某些实施方式中，燃烧器100包括接液盘40，接液盘40设置在底座10上和连接盘24下方，接液盘40与连接盘24间隔以形成第一空气补充通道26。
如此，接液盘40作为空气进入第一空气补充通道26的承接部，使得空气流动更顺畅。同时，接液盘40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清洁，接液盘40还能实现一抹净的效果，减少了用户清洁燃烧器100的麻烦。
具体地，接液盘40和底座10上表面上的凸起11配合，紧密安装在底座10上。接液盘40的上表面低于凸起11的顶端。
如此，凸起11可防止溢出的汤汁沿接液盘40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40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。
在某些实施方式中，燃烧器100包括火盖228，火盖228设置在分气盘22上，分气盘22开设有燃气腔室222，燃气腔室222的底面凸设有进气部2212，火盖228包括与进气部2212相对的分气片2282。
如此，燃气从进气部2212进入燃气腔室222后，冲击分气片2282，燃气的压强增大，流速提高，使燃气和空气的混合气体更快速地均匀分布燃气腔室222，从而使在火盖228处燃烧的火焰更加稳定。
在本发明实施方式中，第一导气管21连通进气部2212。
具体地，进气部2212的上表面与分气片2282的下表面之间的距离为2-4mm。
如此，可保证燃气进入燃气腔室222时达到较快速度，提高燃气燃烧的稳定性。
进气部2212的出口为圆滑圆孔。
如此可使燃气从进气部2212出来时更通畅。
分气片2282为由火盖228向下凹陷而形成的平板状的部分。
如此，结构简单，易于制造。同时，火盖228上凹陷的部分能为燃气补 充少量空气，进一步保证燃气燃烧充分。
本发明实施方式的一种燃气灶具，包括如上任一实施方式的燃烧器100。
本发明实施方式中的燃气灶具中，第一空气补充通道26和第二空气补充通道28采用错层结构，可使第一空气补充通道26和第二空气补充通道28设计成较大尺寸而相互不影响，如此，燃气灶具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。
