Description

一种燃气灶点火结构及灶具
本公开要求于2019年10月23日提交中国专利局、申请号为201911014728.9、发明名称为“一种燃气灶点火结构及灶具”的中国专利申请的优先权，其全部内容通过引用结合在本公开中。
技术领域
本公开涉及家用厨具技术领域，具体涉及一种燃气灶点火结构及灶具。
背景技术
家用燃气灶是日常生活必须的烹饪器具。烹饪后出现的油污或者溢水等会残留部分在火盖，可能导致火孔堵塞。所以保证燃气灶的正常使用，需要定时取下火盖进行清洁。
清洁完成放回火盖时，火盖可能出现未完全放置到位的现象，在这样的情况下继续使用会造成漏火或回火等安全隐患，若长时间这样使用会使火盖、分火器等变形或者烧烂。
相关技术中，燃气灶对于火盖放置均是使用定位销等方式，在没放到位的情况下，会将火盖顶起，用来提示用户火盖没放到位。但是通常情况下顶起高度不够明显，用户还可能会继续使用，从而影响燃气灶的使用寿命，更可能造成安全隐患。
发明内容
因此，本公开要解决的技术问题在于克服相关技术中用户忽视火盖未放置到位，从而提供一种燃气灶点火结构及灶具。
本公开提供一种燃气灶点火结构，包括：
炉头，包括彼此连接的上炉头和下炉头，所述下炉头上设置有过孔；
至少两个检测杆，所述检测杆的顶端平齐设置，至少所述顶端位置设置有导电部，至少两个所述检测杆顶端连线经过所述炉头的圆心，或所述炉头的圆心位于所述检测杆顶端构成的平面图形内部，所述检测杆适于支撑火盖，所述检测杆分别穿过所述过孔；
控制装置，与所述检测杆的导电部串联。
在一些实施方式中，过孔相对所述炉头圆心对称设置。
在一些实施方式中，燃气灶点火结构还包括：支撑架，其上设置有连接孔，所述检测杆的底端可活动地设置在所述连接孔上；
弹性件，设置在所述炉头与所述支撑架之间。
在一些实施方式中，检测杆上有凸出设置的阻挡块，所述阻挡块设于所述下炉头底侧，所述弹性件的一端顶靠在所述阻挡块上。
在一些实施方式中，连接孔上设置有胶圈，所述胶圈的内径大于所述检测杆的外径，所述胶圈设置在所述弹性件的另一端。
在一些实施方式中，检测杆的底端设有挡圈，所述挡圈的外径大于所述胶圈的内径，所述挡圈设置在所述连接孔下端。
在一些实施方式中，支撑架设置在底壳上且所述检测杆与所述底壳之间间隔设置。
在一些实施方式中，上炉头上设置有彼此同心设置的内圆环和外圆环，所述检测杆顶端与所述内圆环或所述外圆环的内侧表面相邻设置。
在一些实施方式中，燃气灶点火结构还包括点火器，所述点火器与所述炉头对应设置，所述控制装置与所述点火器电连接。
在一些实施方式中，控制装置连接有报警装置。
本公开还提供一种灶具，包括上述的燃气灶点火结构。
本公开技术方案，具有如下优点：
1.本公开提供的一种燃气灶点火结构，包括：炉头，包括彼此连接的上炉头和下炉头，所述下炉头上设置有过孔；至少两个检测杆，所述检测杆的顶端平齐设置，至少所述顶端位置设置有导电部，至少两个所述检测杆顶端连线经过所述炉头的圆心，或所述炉头的圆心位于所述检测杆顶端构成的平面图形内部，所述检测杆适于支撑火盖，所述检测杆分别穿过所述过孔；控制装置，与所述检测杆的导电部串联。
火盖通常为金属制成，当火盖放入上炉头位置，与检测杆端部有接触，当火盖放置位置与所有的检测杆接触，则与导电的检测杆串联的控制装置电路导通，并允许燃气灶点火。当至少两个所述检测杆顶端连线经过所述炉头的圆心，或所述炉头的圆心位于所述检测杆顶端构成的平面图形内部通过圆心，则火盖在倾斜状态下无法接触端部平齐的全部检测杆，与检测杆串联的控制装置，无法导通，燃气灶无法进行点火操作。这样的设置，可以准确检测到火盖是否安装到位，且火盖安置无需定位装置，安装火盖的操作更加简洁，此外，火盖在未安放到位则无法执行点火操作，做到了对用户的明确提醒，克服了相关技术中用户忽视容易忽视火盖未放置到位的问题，提高了装置的安全性。
2.本公开提供的燃气灶点火结构，包括：支撑架，其上设置有连接孔，所述检测杆的底端可活动地设置在所述连接孔上；弹性件，设置在所述炉头与所述支撑架之间。
支撑架上设置连接孔使检测杆周向固定，防止检测杆脱离炉头位置，而弹性件的设置使火盖放置好后会压住检测杆，使其下沉，同时与其贴合，使检测杆不会因为安装精度和设计公差等因素的限制，在火盖已经位于完全放置到位，却无法与全部的检测杆进行连接，能够使控制装置的电路与所有的检测杆进行导通，提高了点火结构的容错率；此外设有弹性件的检测减小了火盖在放置不到位等情况下对检测杆的冲击，提高了燃气灶点火结构的使用寿命。
3.本公开提供的燃气灶点火结构，检测杆上有凸出设置的阻挡块，所述阻挡块设于所述下炉头底侧，所述弹性件的一端顶靠在所述阻挡块上。
阻挡块的设置一方面对顶靠在阻挡块上的弹性件起到了限位的作用，另一方面，阻挡块在弹性件作用下抵靠在下炉头底侧，令检测杆突出于下炉头的长度能使火盖在安装到位时接触且轻微挤压检测杆端部，适于检测杆检测到火盖安装状态，使阻挡块起到了安装定位的作用。
4.本公开提供的燃气灶点火结构，所述连接孔上设置有胶圈，所述胶圈的内径大于所述检测杆的外径，所述胶圈设置在所述弹性件的另一端。
检测杆底端设置在连接孔上，并通过胶圈，胶圈的设置一方面对弹性件进行限位，另一方面胶圈作为柔性件能够有效防止检测杆因沿轴向运动而与连接孔产生磨损。
5.本公开提供的燃气灶点火结构，支撑架设置在底壳上且所述检测杆与所述底壳之间间隔设置。
火盖取放过程中接触并挤压检测杆顶端，检测杆沿轴向运动，而支撑架设在底壳上，检测杆底端通过支撑架上的连接孔，检测杆与底壳之间间隔设置可以为检测杆提供下方的活动空间。
6.本公开提供的燃气灶点火结构，包括点火器，所述点火器与所述炉头对 应设置，所述控制装置与所述点火器电连接。
控制装置在接收到用户点火的指令后，检测各个检测杆是否与火盖接触连通，若未收到已连接的信号，则控制点火器不发生点火。这样的设置防止了火盖在未安放正确的情况下继续使用而导致漏火或回火等安全隐患，提高了装置的安全性。

此外，下面所描述的本公开不同实施方式中所涉及的技术特征只要彼此之间未构成冲突就可以相互结合。
如图1-图7，一种燃气灶点火结构，包括：炉头，包括彼此连接的上炉头2和下炉头3，下炉头3上设置有过孔；至少两个检测杆4，检测杆4的顶端平 齐设置，且至少顶端位置设置有导电部41，相邻两个检测杆4与炉头的圆心构成的圆心角相等设置，检测杆4适于支撑火盖1，检测杆4分别穿过过孔；控制装置，与检测杆4的导电部41串联。
火盖1通常为金属制成，当火盖1放入上炉头2位置，与检测杆4端部有接触，当火盖1放置位置与所有的检测杆4接触，则与导电的检测杆4串联的控制装置电路导通，并允许燃气灶点火。当至少两个所述检测杆4顶端连线经过所述炉头的圆心，或所述炉头的圆心位于所述检测杆4顶端构成的平面图形内部通过圆心，则火盖1在倾斜状态下无法接触端部平齐的全部检测杆4，与检测杆4串联的控制装置，无法导通，燃气灶无法进行点火操作。这样的设置，可以准确检测到火盖1是否安装到位，且火盖1安置无需定位装置，安装火盖1的操作更加简洁，此外，火盖1在未安放到位则无法执行点火操作，做到了对用户的明确提醒，克服了相关技术中用户忽视容易忽视火盖1未放置到位的问题，提高了装置的安全性。
在本实施例中，导电部41设在检测杆4顶端位置；检测杆4杆身采用绝缘材料，优选材料为陶瓷，导电部41采用导电金属材料。
火盖1上过孔与检测杆4对应设置，过孔的数量不做限制，在本实施例中为两个且过孔相对炉头圆心对称设置。
作为可变换的实施方式，过孔可以设置多个，且相邻两个过孔与同平面内炉头圆心构成的圆心角相等，过孔沿炉头的圆心周向均匀设置。作为其他可变换的实施方式，过孔可以为炉头镂空的部分。
燃气灶点火结构还包括：支撑架6，其上设置有连接孔，检测杆4的底端可活动地设置在连接孔上；弹性件5，设置在炉头与支撑架6之间。
支撑架6上设置连接孔使检测杆4周向固定，防止检测杆4脱离炉头位置，而弹性件5的设置使火盖1放置好后会压住检测杆4，使其下沉，同时与其贴 合，使检测杆4不会因为安装精度和设计公差等因素的限制，在火盖1已经位于完全放置到位，却无法与全部的检测杆4进行连接，能够使控制装置的电路与所有的检测杆4进行导通，提高了点火结构的容错率；此外设有弹性件5的检测减小了火盖1在放置不到位等情况下对检测杆4的冲击，提高了燃气灶点火结构的使用寿命。
在本实施例中，支撑架6设置在下炉头3下方位置，与灶具底壳7采用螺钉进行连接，连接的具体形式不做限制，可以使用焊接、铆接等常用连接方式。
检测杆4上有凸出设置的阻挡块42，阻挡块42设于下炉头3底侧，弹性件5的一端顶靠在阻挡块42上。在本实施例中，阻挡块42沿检测杆4径向均匀凸起。
阻挡块42的设置一方面对顶靠在阻挡块42上的弹性件5起到了限位的作用，另一方面，阻挡块42在弹性件5作用下抵靠在下炉头3底侧，令检测杆4突出于下炉头3的长度能使火盖1在安装到位时接触且轻微挤压检测杆4端部，适于检测杆4检测到火盖1安装状态，使阻挡块42起到了安装定位的作用。
连接孔上设置有胶圈61，胶圈61的内径大于检测杆4的外径，胶圈61设置在弹性件5的另一端。检测杆4通过胶圈61，底端设置在连接孔上，胶圈61的设置一方面对弹性件5进行限位，另一方面胶圈61作为柔性件能够有效防止检测杆4因沿轴向运动而与连接孔产生磨损。在本实施例中，弹性件5为弹簧。
检测杆4的底端设有挡圈43，挡圈43的外径大于胶圈61的内径，挡圈43设置在连接孔下端。挡圈43与阻挡块42配合设置对检测杆4进行限位，防止检测杆4底端脱离支撑架6，保证燃气灶点火装置在火盖1放置前后的稳定状态。
支撑架6设置在底壳7上且检测杆4与底壳7之间间隔设置。火盖1取放过程中接触并挤压检测杆4顶端，检测杆4沿轴向运动，而支撑架6设在 底壳7上，检测杆4底端通过支撑架6上的连接孔，检测杆4与底壳7之间间隔设置可以为检测杆4提供下方的活动空间。
上炉头2上设有彼此同心的内圆环21和外圆环22，检测杆4顶端与内圆环21或外圆环22的内侧表面相邻设置。内圆环21和外圆环22分别适于安装内环火盖和外环火盖，内环火盖在炉头与内圆环21内侧贴合安设，外环火盖与外圆环22内侧贴合安设，各检测杆4导电部41为了有效检测火盖是否安装到位，需要与不同圆环的内侧表面相邻设置。在本实施例中，检测杆4与上炉头2圆环内侧表面有间距，这是为了避免检测杆4在发生位移时与炉头产生磨损，影响点火装置的使用寿命。
燃气灶点火结构，还包括点火器8，点火器8与炉头对应设置，控制装置与点火器8电连接。控制装置连接有报警装置。在本实施例中，报警装置为蜂鸣器。
用户打开点火开关，控制装置在收到用户打开点火开关的信息后，先检测各连接杆的导电部41是否与火盖1全部导通，已全部导通则执行点火操作，控制点火器8打开并点火；未导通则控制报警装置执行报警提示，不执行点火操作。报警装置的设置及时提醒用户火盖1未放置到位。
本公开还提供一种灶具，包括上述的燃气灶点火结构。
显然，上述实施例仅仅是为清楚地说明所作的举例，而并非对实施方式的限定。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。而由此所引伸出的显而易见的变化或变动仍处于本公开创造的保护范围之中。
