实施例一
请参阅图1-图4，本申请实施方式的一种燃烧器10，包括分火器11，分火器11大致呈长条形且形成有燃气腔室111，燃气腔室111的底部开设有间隔的至少两个进气口112，至少两个进气口112沿燃烧器10的长度方向排列，进气口112用于将燃气导入燃气腔室111，燃气腔室111的侧壁形成有火孔12，火孔12与燃气腔室111连通。
上述燃烧器10中，燃气腔室111的底部设置有沿燃烧器10的长度方向排列的至少两个进气口112，一方面，有助于使燃气更均匀地分布在燃气腔室111的各处，从而使到达火孔12处的燃气流速更均匀，提高了热效率和降低了一氧化碳的排放量，另一方面由于增大了进气面积，从而提高了燃烧器10的热负荷。
本申请实施方式的燃烧器10可应用于燃气灶具、烤箱等使用燃气加热的烹饪器具。燃烧器10可应用于鱼形燃烧器。
具体地，燃烧器10大致呈长条形，平面形状可以是矩形、椭圆形或其他组合图形，也可以是鱼形等不规则图形。本申请实施方式的燃烧器10中间尺寸较大，两端尺寸较小。在图示的示例中，燃烧器10的平面形状大致呈两个梯形在两个梯形的长底边连接的形状。另外，燃气腔室111的边角可呈圆弧形，这样燃烧器10内部没有死角，便于清洁，也使得燃烧器10的外观更加美观。
由于燃烧器10大致呈长条形，至少两个进气口112沿燃烧器10的长度方向排列，这样更便于设置燃烧器10的进气管14。可将燃烧器10沿长度方向分为若干个面积相等的区域，在每个区域的中心位置设置一个进气口112。当然，进气口112的设置方式不限于上述方式，在其他实施方式中，可根据燃烧器10的形状及使用需求采用其他设置方式。较佳地，至少两个进气口112位于同一直线上。
进气口112的数量为2个，也可以为3个、4个或其他任意多个。本申请实施方式中，进气口112的数量为两个，两个进气口112沿燃气器10的中心轴X对称设置。这样使得燃气在燃气腔室111内分布更均匀，也更便于进气。
在某些实施方式中，分火器11包括底板113，燃烧器10包括引射管13，引射管13设置在底板113的下表面并连接进气口112。如此，引射管13将燃气从进气口112导入燃气腔室111内，保证了燃气腔室111的进气量。
具体地，引射管13垂直于底板113设置。如此，燃气垂直流入燃气腔室111内，有助于使得燃气在燃气腔室111内分布更均匀。在一个例子中，引射管13与出气口142同轴设置。有助于燃气沿引射管13及出气口142的轴线进入引射管13内与一次空气均匀混合。
在某些实施方式中，分火器11包括多个加强筋114，多个加强筋114连接底板113的下表面和引射管13，多个加强筋114环绕引射管13的周向均匀间隔设置。如此，多 个加强筋114加强引射管13和底板113的连接，使引射管13更稳定地设置在底板113的下表面，从而使得燃烧器10的结构更稳定。
具体地，沿每个引射管13的周向均匀设置有4个加强筋114。如此，四个加强筋114可较好地限制引射管13四个方向的偏移或歪斜，可以避免引射管13偏移或歪斜而导致燃气进入燃气腔室111的方向偏移或歪斜，有助于使得燃气在燃气腔室111内分布更均匀。
在某些实施方式中，燃烧器10包括进气管14，进气管14开设有至少两个出气口142，每个出气口142分别与对应的一个引射管13的入口132相对设置，进气管14沿燃烧器10的长度方向延伸。如此，燃气从进气管14流至出气口142，再从出气口142流至引射管13后流入燃气腔室111内。
进一步地，进气管14连接燃气源，可在进气管14的入口处设置电磁阀控制进气管14与燃气源的通断。这样电磁阀可以在不需要使用燃烧器10或者燃烧器10的热电偶检测到燃气没有燃烧时，切断燃气源，避免燃气泄漏。
在某些实施方式中，燃烧器10包括喷嘴15，喷嘴15安装在出气口142处并与引射管13的入口132相对间隔设置。如此，燃气从喷嘴15喷出后进入引射管13，喷嘴15可对进气管14出射的气流进行加压，保证了燃气腔室111的气流供应稳定。
具体地，燃气从喷嘴15喷出，在喷嘴15与引射管13之间的间隔处，与空气混合后，空气和燃气的混合气体从引射管13进入燃气腔室111内。如此，在喷嘴15与引射管13之间的间隔处补充一次空气，使燃气在火孔12处燃烧更充分，有助于提高热效率和降低一氧化碳的排放量。
在某些实施方式中，燃烧器10包括底杯16，分火器11承载在底杯16，进气管14设置在底杯16。如此，实现进气管14和分火器11较好地装配。
具体地，底杯16形成上端开放的容腔162，引射管13位于容腔162内的侧壁开设入口132，喷嘴15可置于容腔162内。这样可以较好地保护引射管13的入口132和喷嘴15。
进一步地，底杯16的侧壁设置有点火针安装部164和热电偶安装部166。如此，燃烧器10的点火针可安装在点火针安装部164，燃烧器10的热电偶可安装在热电偶安装部166。
进气管14设置在底杯16的底部，这样有助于减小底杯16的高度，从而可减小燃烧器10的体积。进气管14与底杯16可为一体结构。这样便于燃烧器10的生产制造，也使得燃烧器10的结构更加稳定。
当然，在其他实施方式中，进气管14不限于设置在底杯16的底部，也可以设置 在底杯16的其它位置；进气管14和底杯16也不限于一体结构。
在某些实施方式中，分火器11包括连接在底板113下表面边缘的下侧板115，下侧板115承载在底杯16的侧壁上，下侧板115与底杯16的侧壁之间形成有一次空气进气通道167。如此，一次空气可从一次空气进气通道167进入容腔162内，一次空气可流至喷嘴15与引射管13之间的间隔处，与从喷嘴15喷出的燃气混合后，进入燃气腔室111内，为燃气燃烧补充氧气，有助于提高热效率和降低一氧化碳的排放量。
具体地，底板113的两侧边缘为圆弧形，下侧板115包括连接底板113两侧边缘的两个子侧板116，请参图4，子侧板116为从上至下逐渐外扩的弧形板；底杯16的侧壁呈顶部等高的框状。如此，子侧板116支撑在底杯16的侧壁的四个顶角处，一方面使得一次空气可从子侧板116与底杯16的侧壁之间形成的一次空气进气通道167流至喷嘴15与引射管13之间的间隔处，另一方面也使得分火器11稳定地承载在底杯16。进一步地，下侧板115呈帽沿状并罩设在底杯16上端的开口处，可起到避免杂质进入到底杯16内的作用。
在某些实施方式中，燃烧器10包括火盖17，火盖17设置在分火器11的顶部并覆盖燃气腔室111。如此，可避免燃气从燃气腔室111顶部泄漏，也能够避免汤汁、杂质落入燃气腔室111内，影响燃烧器10正常工作。
具体地，燃气从进气口112垂直射入燃气腔室111后，在火盖17的作用下，可使燃气改变流动方向朝四周流动，有助于使得燃气在燃气腔室111内分布更均匀。
在某些实施方式中，火孔12环绕燃气腔室111的周向均匀分布。如此，形成环形火焰，使得燃烧器10的加热效果更好。
具体地，分火器11包括连接在底板113上表面边缘的上侧板117，火盖17承载在上侧板117的顶部。
本申请实施方式中，火孔12形成在上侧板117的顶部，这样简化了火盖17的结构，火盖17为整块板，可较好地避免杂质落入燃气腔室111内。当然，在其他实施方式中，火孔12也可以形成在火盖17的边缘处。
进一步地，上侧板117、底板113和下侧板115为一体结构，这样分火器11为一个整体结构，便于燃烧器10的装配，也使得燃烧器10结构更稳定。
在图示的实施方式中，火盖17和分火器11大致呈跑道形。
本申请实施方式的一种烹饪器具，包括上述任一实施方式的燃烧器10。
本申请实施方式的烹饪器具，燃烧器10的燃气腔室111的底部设置有沿燃烧器10的长度方向排列的至少两个进气口112，一方面，有助于使燃气更均匀地分布在燃气腔室111的各处，从而使到达火孔12处的燃气流速更均匀，提高了热效率和降低了一氧 化碳的排放量，另一方面由于增大了进气面积，从而提高了燃烧器10的热负荷。
烹饪器具包括但不限于燃气灶具或烤箱。
实施例二
请参阅图5-图9，本申请实施方式提供一种燃烧器30，燃烧器30包括分火器31和底杯36，分火器31大致呈长条形且设置在底杯36上，分火器31形成有燃气腔室311，燃气腔室311的底部开设有间隔的至少两个进气口312，至少两个进气口312沿分火器31的长度方向排列，燃烧器30的侧壁形成有火孔32，火孔32与燃气腔室311连通，分火器31包括底板313和连接在底板313下表面的加强部35，底杯36内设置有与加强部35对应的安装部361，安装部361形成有定位结构360，加强部35设在定位结构360上并承载在安装部361。
本申请实施方式的燃烧器30，燃气腔室311的底部设置有沿分火器31的长度方向排列的至少两个进气口312，一方面，有助于使燃气更均匀地分布在燃气腔室311的各处，从而使到达火孔32处的燃气流速更均匀，提高了热效率和降低了一氧化碳的排放量，另一方面由于增大了进气面积，从而提高了燃烧器30的热负荷。而且加强部35设在定位结构360，便于将分火器31安装在底杯36，从而有助于提高装配效率，加强部35还起到增强底板313强度的作用。
本申请实施方式的燃烧器30可应用于燃气灶具、烤箱等使用燃气加热的烹饪器具。
具体地，分火器31大致呈长条形，平面形状可以是矩形、跑道形、椭圆形或其他组合图形，也可以是鱼形等不规则图形。本申请实施方式的分火器31的平面形状大致呈跑道形，即呈中间矩形、矩形的两侧连接有两个半圆的形状。这样，燃气腔室311的边角呈圆弧形，燃烧器30内部没有死角，便于清洁，也使得燃烧器30的外观更加美观。燃气腔室311的形状与分火器31的形状基本一致。
由于分火器31大致呈长条形，至少两个进气口312沿分火器31的长度方向排列，这样更便于设置燃烧器30的进气管34。可将分火器31沿长度方向分为若干个面积相等的区域，在每个区域的中心位置设置一个进气口312。当然，进气口312的设置方式不限于上述方式，在其他实施方式中，可根据燃烧器30的形状及使用需求采用其他设置方式。较佳地，至少两个进气口312位于同一直线上。

进一步地，每个安装板3622的两端分别连接底杯36相对的两个侧壁，两个第二安装部363分别设置在底杯36的相对两个侧壁。这样安装部361的结构稳定，从而使得分火器31更稳定地设置在底杯36上，燃烧器30的结构更稳定。

具体地，引射管33与出气口342同轴。如此，引射管33、进气口312与出气口342对准，燃气从出气口342射出后流至引射管33内，并垂直进入燃气腔室311。
进一步地，在图示的示例中，进气口312的数量为两个，引射管33的数量为两个，第一加强筋353连接两个引射管33和底板313，使引射管33更稳定地设置在底板313的下表面，从而使得燃烧器30的结构更稳定。可以理解，引射管33的数量与进气口312的数量一致。
更进一步地，底杯36形成上端开放的容腔365，引射管33位于容腔365内的端部开设入口132。这样可以较好地保护引射管33的入口132。

在某些实施方式中，燃烧器30包括喷嘴(图未示)，喷嘴安装在出气口342处并与引射管33的入口相对间隔设置。如此，燃气从喷嘴喷出后进入引射管33，喷嘴可对进气管34出射的气流进行加压，保证了燃气腔室311的气流供应稳定。
具体地，燃气从喷嘴喷出，在喷嘴与引射管33之间的间隔处，与空气混合后，空气和燃气的混合气体从引射管33由进气口312出射至燃气腔室311内。如此，在出气口342与引射管33之间的间隔处补充一次空气，使燃气在火孔32处燃烧更充分，有助于提高热效率和降低一氧化碳的排放量。
在某些实施方式中，火孔32包括交错间隔设置的多个主火孔322和多个传火孔324，传火孔324的尺寸小于主火孔322的尺寸。如此，可通过传火孔324使相邻的主火孔322之间相互传火，使燃烧器30的火焰更稳定。
具体地，相邻的两个主火孔322之间设置有至少一个传火孔324，这样传火孔324传火的效果更好。
进一步地，分火器31包括连接在底板313上表面边缘的上侧板317，上侧板317的上表面开设火孔32，火盖37承载在上侧板317的顶部。可以使多个火孔32间隔设置，使得燃烧效果好，也使得火盖37可以更稳定地设置在分火器31上。而且，这样也简化了火盖37的结构，火盖37为整块板，可较好地避免杂质落入燃气腔室311内。当然，在其他实施方式中，火孔32也可以形成在火盖37的边缘处或者上侧板317的其它位置；还可以是部分火孔32形成在分火器31处，部分火孔32形成在火盖37处等。
分隔板318的两侧连接上侧板317的两个侧壁，将燃气腔室311分隔开。在图6所示的实施方式中，分隔板318位于燃烧器30的中心轴X处，这样使燃气在燃气腔室311内分布更均匀，从两个进气口312流入燃气腔室311内的燃气之间干扰更小，燃烧 效果更好。
在某些实施方式中，分火器31包括设置在底板313上表面的多个第一凸块319，第一凸块319连接上侧板317的内表面，第一凸块319的顶部和上侧板317的内表面配合形成卡槽3192，火盖37的下表面设置有环状的第二凸块372，第二凸块372卡设在卡槽3192内。这样便于将火盖37设置在分火器31，可通过卡槽3192限定火盖37的位置，使燃烧器30的结构更稳定。而且火盖37与分火器31的结合更紧密，防止燃气泄漏。
