以下结合具体实施例对本申请的实现进行详细的描述。
如图1-图4所示，本申请实施例提出了一种炉头700，包括底座1、安装于底座1的离子针2、与底座1相连且环绕离子针2设置的隔离罩3，以及安装于隔离罩3的顶部且用于与锅800接触的支撑环4；底座1开设有适配于隔离罩3的隔离槽11，隔离罩3安装于隔离槽11内，隔离罩3与隔离槽11的内壁相抵接；隔离罩3为绝缘罩（可为耐高温塑料、玻璃、陶瓷及大理石等材质），底座1为绝缘座（可为耐高温塑料、玻璃、陶瓷及大理石等材质）。
在本申请的实施例中，将隔离罩3选为绝缘罩，底座1选为绝缘座，因此离子针2与隔离罩3及底座1之间均不易于产生高压拉弧，不会将离子针2处的高压引导至底座1及隔离罩3处，也即不会将离子针2处的高压引导至边缘处，进而有效避免了将离子针2处的高压引导至炉头700的外部，实现了对炉头700内的高电压的初步隔离。隔离罩3以嵌入的方式安装于隔离槽11内，进而增加了炉头700内的高压通过爬电的方式向外传播，也即增加了爬电距离，进一步对炉头700内的高压进行隔离。
拉弧：电压超过空气的耐受力使空气电离变成导体也就是产生电弧电弧一般会绕过绝缘体沿着绝缘体的表面产生因而会对绝缘体产生损坏如电弧的高温会使绝缘体融化或碎裂。辟如开关上表明额定短路开断电流20KA,表示20KA内的短路跳闸触头灭弧热元件动作等有效，超过这个绝限跳闸接头灭弧热元件动作不保证，会产生拉弧。
爬电：在绝缘材料的性能降低时受天气等外界因素如空气湿度大，接连阴天霉雨季节，潮湿环境等使得带电金属部位与绝缘材料产生象水纹样电弧沿着外皮爬的现象。
爬电距离：爬电距离指沿绝缘表面测得的两个导电零部件之间，在不同的使用情况下，由于导体周围的绝缘材料被电极化，导致绝缘材料呈现带电现象的带电区。
进一步地，请参阅图2-图3，作为本申请提供的炉头700的另一种具体实施方式，底座1开设有安装槽12，离子针2固定安装于安装槽12内，安装槽12的内侧壁开设有排气孔13，底座1于排气孔13处设有隔离台14，隔离台14开设有与排气孔13相通的隔离通孔141。排气孔13处设置隔离台14，以增加爬电距离，以避免高压从排气孔13处向炉头700外部传播。
进一步地，请参阅图2，作为本申请提供的炉头700的另一种具体实施方式，隔离台14由底座1的表面向远离底座1的中心的方向延伸形成。也即隔离台14与底座1为一体件，隔离台14与底座1之间没有间隙，避免高压从隔离台14与底座1之间的间隙向外传播。
进一步地，请参阅图2-图3，作为本申请提供的炉头700的另一种具体实施方式，还包括用于封闭安装槽12的隔离板5，隔离板5为微晶玻璃板，隔离板5开设有让位孔51，离子针2贯穿让位孔51。隔离板5将安装槽12封闭，离子针2贯穿让位孔51，隔离板5隔绝了离子针2的顶部与排气孔13之间的传播路径，进一步避免了离子针2的顶部的高压通过排气孔13向外传播。
进一步地，请参阅图2，作为本申请提供的炉头700的另一种具体实施方式，离子针2与让位孔51的内壁之间设有硅胶圈或者离子针2通过硅胶与让位孔51的内壁相连。硅胶圈或者硅胶将离子针2与让位孔51内壁之间的间隙进行封堵，以便离子针2与让位孔51内壁之间的间隙连通离子针2的顶部及排气孔13。
进一步地，请参阅图2-图3，作为本申请提供的炉头700的另一种具体实施方式，支撑环4与隔离罩3之间设有隔离圈6，隔离圈6为绝缘圈。隔离圈6用于封闭支撑环4与隔离罩3之间的间隙，避免炉头700内部通过支撑环4与隔离罩3之间的间隙与外界相通，以进一步提升对炉头700内部高压的隔离效果。
进一步地，请参阅图2-图3，作为本申请提供的炉头700的另一种具体实施方式，隔离罩3为透明玻璃罩，实现隔离的同时还可贯穿内部离子针2的工作状态；支撑环4为陶瓷环，也可为其他金属环，选为金属环时虽然隔离高压效果差，但其直接与锅800的底部接触，安全隐患比较低。
进一步地，请参阅图2-图3，作为本申请提供的炉头700的另一种具体实施方式，底座1上设有抵接环15，抵接环15与隔离罩3的外侧壁相抵接，以进一步增加爬电距离，提升对高压的隔离效果。
如图1-图4所示，本申请实施例还提出了一种炉头700，包括底座1、安装于底座1的离子针2、与底座1相连且环绕离子针2设置的隔离罩3，以及安装于隔离罩3的顶部且用于与锅800接触的支撑环4；底座1开设有适配于隔离罩3的隔离槽11，隔离罩3安装于隔离槽11内，隔离罩3与隔离槽11的内壁相抵接；隔离罩3为绝缘罩，底座1为绝缘座；底座1开设有安装槽12，离子针2固定安装于安装槽12内，安装槽12的内侧壁开设有排气孔13，底座1于排气孔13处设有隔离台14，隔离台14开设有与排气孔13相通的隔离通孔141；炉头700还包括用于封闭安装槽12的隔离板5，隔离板5为微晶玻璃板，隔离板5开设有让位孔51，离子针2贯穿让位孔51；底座1上设有抵接环15，抵接环15与隔离罩3的外侧壁相抵接。
在本申请的实施例中，将隔离罩3选为绝缘罩，底座1选为绝缘座，因此离子针2与隔离罩3及底座1之间均不易于产生高压拉弧，不会将离子针2处的高压引导至底座1及隔离罩3处，也即不会将离子针2处的高压引导至边缘处，进而有效避免了将离子针2处的高压引导至炉头700的外部，实现了对炉头700内的高电压的初步隔离。隔离罩3以嵌入的方式安装于隔离槽11内，进而增加了炉头700内的高压通过爬电的方式向外传播，也即增加了爬电距离，进一步对炉头700内的高压进行隔离。排气孔13处设置隔离台14，以增加爬电距离，以避免高压从排气孔13处向炉头700外部传播。
隔离台14由底座1的表面向远离底座1的中心的方向延伸形成。也即隔离台14与底座1为一体件，隔离台14与底座1之间没有间隙，避免高压从隔离台14与底座1之间的间隙向外传播。隔离板5将安装槽12封闭，离子针2贯穿让位孔51，隔离板5隔绝了离子针2的顶部与排气孔13之间的传播路径，进一步避免了离子针2的顶部的高压通过排气孔13向外传播。硅胶圈或者硅胶将离子针2与让位孔51内壁之间的间隙进行封堵，以便离子针2与让位孔51内壁之间的间隙连通离子针2的顶部及排气孔13。
隔离圈6用于封闭支撑环4与隔离罩3之间的间隙，避免炉头700内部通过支撑环4与隔离罩3之间的间隙与外界相通，以进一步提升对炉头700内部高压的隔离效果。隔离罩3为透明玻璃罩，实现隔离的同时还可贯穿内部离子针2的工作状态；支撑环4为陶瓷环，也可为其他金属环，选为金属环时虽然隔离高压效果差，但其直接与锅800的底部接触，安全隐患比较低。
本申请实施例又提出了一种电焰灶，包括机箱及上述实施例中的炉头700。机箱内设有电控板及变压器等电焰灶必备的组件。
可以理解的是，另一种具体实施方式中的方案可为在其他实施例的基础上进一步改进的可实现的实施方案。
显然，本申请的上述实施例仅仅是为了清楚说明本申请所作的举例，而并非是对本申请的实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。凡在本申请的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本申请权利要求的保护范围之内。
