本公开涉及温度检测技术领域，具体而言，涉及一种温度传感器、燃气灶及其温度监控和控火的方法。
背景技术
燃气灶是指以液化石油气或者天然气等气体燃料进行直火加热的厨房用具，目前市面上的燃气灶没有温度监控器件，烹饪时无法了解烹饪器皿的实际温度，无法较好掌控烹饪食物的制作过程，来确保色香味俱全。
另一方面烹饪器皿干烧时极易造成爆炸等安全事故，因此在洗刷锅具或者更换炊具等过程中为了避免火灾以及煤气泄漏等情况发生，需要经常点火和熄火，而这无疑浪费了做饭人员的精力。

请参阅图1-图8，本公开提供一种温度传感器，包括干簧管单元、磁铁2、可检测温度的测温探头单元以及配置成隔离磁铁2和干簧管1的隔磁管3，干簧管单元包括可受磁铁2的磁性影响而由常开状态变为闭合状态的干簧管1。测温探头单元包括测温探头4和第一连接器5，测温探头4配置成坐锅时向下移动并带动隔磁管3运动以使干簧管1受到磁性影响，第一连接器5配置成与 配置成获知当前温度的温度监控组件连通，测温探头4与第一连接器5电连接。干簧管单元还包括配置成与配置成控制点火、熄火或小火的控火组件连通的第二连接器6，干簧管1与第二连接器6电连接。
在本公开中，干簧管1的特性是受到磁铁2影响后会由常开状态变为闭合状态，以实现电路的导通，因此本公开合理利用干簧管1的特性，预先采用隔磁管3将磁铁2和干簧管1隔离开来，可选的，该隔磁管3挡在磁铁2和干簧管1之间，然后再利用坐锅时测温探头4会向下移动的特性，而带动着隔磁管3移动，以使隔离管3移动后离开挡在磁铁2和干簧管1之间的位置，那么此时的干簧管1就会受到磁铁2影响而从常开状态变为闭合状态，即导通，并通过第二连接器6将信号传至控火组件中，控火组件得到信号后即可进行打火，从而达到了坐锅打火的效果。而当移锅时，测温探头4向上移动，会带着隔磁管3回到原位，隔离管3再次隔开磁铁2和干簧管1，干簧管1由闭合状态变为常开状态，控火组件断电，则控制熄火或者是小火，就能够有效改善因为没有关火或者是干烧而带来的安全隐患。需要说明的是，控火组件断电后，控火组件控制熄火还是小火，按需选择即可，本公开中不作具体限定。另一方面，坐锅时，测温探头4会触到锅底，锅底的温度通过测温探头4并借助第一连接器5反馈至温度监控组件，温度监控组件就会将该温度传递给用户，用户可以根据该温度来自由控制火力大小。同时，由于在移锅前，测温探头4持续接触锅底，所以其传递的温度是实时的，变化的，如此可以将该锅底的温度真实地反应给用户，以达到精确控温的效果，应当理解，该温度监控组件如何将温度反应给用户的方式多种多样，例如，将温度信息转换为数字信号在显示屏中显示，以直观地反馈给用户，或者是通过扬声器播报声音，都是可行的，本公开中不作一一列举。
可选的，测温探头4为耐高温感温探头。
可选的，干簧管单元还包括铁氟龙套管23、第二电线14和自熄套管15，干簧管1两端引线分别与两根第二电线14的一端连接，铁氟龙套管23套入干簧管1进行防护，再将自熄套管15套入电线抵住铁氟龙套管23进行防护，最后插入三段式结构中的第三段22中，并通过高温密封胶进行固定，第二电线14尾部与第二连接器6连接便于与控火组件连接。
本公开中，可选的，测温单元还包括配置成配合测温探头4向下移动或向上移动的测温探头支撑组件。在本公开中，测温探头4在坐锅时需要向下移动，在移锅时需要向上移动，温探头支撑组件能够驱动测温探头4运动以实现测温探头4的上下往复移动。
可选的，请参阅图1和图2，测温探头支撑组件包括弹簧7、两侧均设有滑轨81的滑动管8以及具有两条导向槽91的导向管9，测温探头4的外壁与 导向管9的内腔滑动配合，滑动管8穿过导向管9，两条滑轨81分别与两条导向槽91滑动配合，既具有导向的作用，使导向管9与滑道管8稳定地滑动，还能够使滑动管8与导向管9在滑动管8的周向上保持相对固定，也即滑动管8和导向管9不会相对转动，结构紧凑，不易损坏。可选的，滑轨81沿滑动管8的轴线方向延伸，导向槽91沿导向管9的轴线方向延伸。弹簧7位于滑动管8的支撑面与测温探头4的底面之间，弹簧7的两端分别与支撑面和底面抵持。在本公开中，弹簧7的作用是在移锅后回弹，以达到测温探头4向上移动的目的，而导向管9和滑动管8均是测温探头4移动的保障，测温探头4的移动量控制在(0～25)mm之间，以使本温度传感器结构紧凑，方便装配至燃气灶中。
请参阅图1-图3，可选的，该测温探头单元还包括设于最外侧的防护罩16，防护罩16套设在导向管9外，可以保护内部的弹簧7、滑动管8、导向管9以及测温探头4等部件，提高温度传感器的安全性。需要说明的是，还可以采用其他弹性材质制成的弹性件替换弹簧7，只要能够实现移锅后回弹，并驱动测温探头4向上移动即可，此处就不再赘述。
可选的，防护罩16的一端与导向管9连接，另一端设置有供测温探头4伸出的开孔，防护罩16与导向管9连接的管段的外径收缩，且大于导向管9的外径，直接将导向管9的端部插接在防护罩16外径收缩的一端即可，连接方式简单，便于与导向管9连接。换句话说，防护罩包括第一管段161、连接盘162以及第二管段163，连接盘162中部设置有孔，第一管段161的一端与连接盘162连接，第二管段163的一端与连接盘162连接，第一管段161与第二管段163通过连接盘162上的孔连通；第二管段163套设在滑动管外且与滑动管连接，第一管段161套设在导向管外；第一管段161的内径大于第二管段163的外径。连接盘162上设置有多个散热孔164，每个散热孔164均同时连通第一管段161和第二管段163，多个散热孔164沿连接盘162的周向间隔排布。
测温探头4漏出防护罩16设置有开孔的端面所在平面0.4mm-0.6mm，例如测温探头4漏出防护罩16设置有开孔的端面所在平面0.5mm。可选的防护罩16大小径过渡部位开设多个散热孔164，多个散热孔164沿防护罩16的周向均匀间隔排布，配置成空气流通散热，实现真实感温。
可选的，测温单元还包括配置成传输测温信号的测温信号传输组件。在本公开中，测温单元测得的温度需要传递至温度监控组件以供用户获知，因此采用该测温信号传输组件来进行温度传输。
可选的，请参阅图1和图2，测温信号传输组件包括可伸至测温探头4的内腔中并固定的热敏电阻10，热敏电阻10的头部与测温探头4内腔的底部接 触并随测温探头4一起移动，且热敏电阻10通过第一电线13与第一连接器5电连接，隔磁管3安装在第一电线13上，随第一电线13的运动而运动。在本公开中，热敏电阻10是感应温度的，它属于本温度传感器的核心，该测温信号传输组件可以随着测温探头4一起移动，从而带动设置在第一电线13上的隔磁管3一起移动，进而能够到达上述控火的目的。可选的，第一电线13外侧还设有高温绝缘套管12和自熄套管15，起到保护第一电线13的作用。可选的，热敏电阻10通过耐高温密封胶11固定在测温探头4的内腔中。可选的，隔磁管3为隔磁材料制成，起到隔绝磁铁2对干簧管1的影响的作用，隔磁管3设置为两段式结构，其头部为管状结构，尾部为端子压接形状，即尾部设置为变形部，能够在外力作用下发生形变，且不会自动恢复形变。尾部的外径比头部更细，且尾部与第一电线13压接固定，使之更够随着第一电线13的移动而移动，以做到同步活动。
可选的，请参阅图1-图3，测温单元还包括供第一电线13插入并滑动的直管19，隔磁管3滑动设置于直管19内，隔磁管3沿直管19的延伸方向相对于直管19往复滑动；直管19位于磁铁2和干簧管1之间。在本公开中，第一电线13和设于第一电线13端部的热敏电阻10插入直管19并穿过直管19再进入到测温探头4的内腔中。在第一电线13和热敏电阻10随着测温探头4移动的过程中，隔磁管3会在第一电线13的驱动下在直管19中运动，因此隔磁管3的外径应当小于直管19，减小隔磁管3与直管19之间的摩擦，且隔磁管3滑动更加灵活。可选的，在直管19与测温探头4之间还设有弯管18，直管19和测温探头4通过该弯管18连接，可以优化空间布局，使得本温度传感器更适合于现有的燃气灶，使之更为大众化。可选的，弯管18的一端距离管口6mm的位置设置数个冲点进行限位，将测温探头4的滑动管8套入后进行连接。可选的，直管19的一端距离管口5mm的位置扩孔，套入弯管18的另一端后进行连接，弯管18的另一端翻口避免刮伤上述的各类套管及隔磁管3。
可选的，请参阅图1、图4、图5和图6，本温度传感器还包括配置成固定磁铁2和干簧管1以及配置成维持磁铁2和干簧管1之间的位置关系不变的固定组件200。在本公开中，为了保证磁铁2和干簧管1之间的位置关系不易变动，以保证干簧管1具有稳定的状态，需要采用固定组件200来将二者进行定位并固定。
可选的，请参阅图1、图4、图5和图6，固定组件200设置为三段式结构，固定组件200包括安置并定位磁铁2的第一段20、配置成定位隔磁管3的第二段21以及配置成安置并定位干簧管1的第三段22，第一段20、第二段21和第三段22沿磁铁2至干簧管1的方向依次排布，第一段20与第二段21连接，第二段21与第三段22连接，可选的，第一段20、第二段21和第三段22可以一体成型。在本公开中，固定组件200设置为三段式结构，其中第一段20和第三段22均为管状结构，例如，第一段20和第三段22均为不锈钢钢 管，分别供磁铁2和干簧管1安置并固定。可选的，第一段20和第三段22的一端敞口另一端封闭，灰尘等杂质不易从封闭端进入，更加清洁卫生。可选的，第一段20和第三段22分别与其安置的磁铁2或干簧管1的形状相匹配，至少是能够供磁铁2和干簧管1插入，例如磁铁2为永久性磁铁2，其形状可以是条形或者是圆形，两端面为极面，第一段20应当能够供其插入，然后通过耐高温的密封胶进行固定。干簧管1的形状不作具体限定，干簧管1能够插入第三段22即可。另外，第二段21为弧形结构，其弯曲的弧度当与直管19的外周面一致，以便于与直管19贴合连接，可选的，该弧形结构为弧形弹片，第二段21具有一定的弹性，能够在一定范围内发生形变，便于将直管19卡入第二段21中，且第二段21能够夹持直管19，二者的连接方便，且连接牢固可靠。可选的，第二段11的横截面形状为优弧，增大与直管19的接触面积，夹持更加稳定可靠。可选的，干簧管1通过耐高温密封胶固定在第三段22中。可选的，固定组件200的三段式结构为一体成型结构，位置固定，便于操作，避免了单个的第一段20、第二段21和第三段22在装配过程中固定困难，位置不统一等缺点。

本公开提供了一种燃气灶的温度监控和控火的方法，包括如下步骤：
S1，在坐锅时，测温探头4向下移动以驱使隔离管3移动；
S2，在隔离管3移动后，隔离管3离开挡在磁铁2和干簧管1之间的位置，干簧管1受到磁铁2磁性的影响而由常开状态变为闭合状态，此时控火组件得电，进行点火；同时，测温探头4触及锅底，并将检测到的温度信号传递至温度监控组件，温度监控组件获知当前温度信息并显示和/或者播报；
S3，在移锅时，测温探头4向上移动再次驱使隔离管移动；
S4，在隔离管再次移动后，隔离管恢复至挡在磁铁2和干簧管1之间的位 置，干簧管1不再受到磁铁2磁性的影响而由闭合状态变为常开状态，此时控火组件失电，控火组件控制燃气灶熄火或小火；同时，测温探头4离开锅底，不再检测温度信号，温度监控组件停止工作。
在本公开中，详细地说明了采用了上述的温度传感器后的燃气灶的温度监控和控火的方法，温度监控组件和控火组件通过与上述提到的温度传感器进行配合，从而达到了坐锅打火以及移锅熄火或小火的目的，能够有效改善因为没有关火或者是干烧而带来的安全隐患，另一方面，锅底的温度会通过测温探头4并借助第一连接器5反馈至温度监控组件，温度监控组件将该温度传递给用户，用户可以根据该温度来自由控制火力大小，同时，由于在移锅前，测温探头4都会持续接触锅底，所以其传递的温度是实时的，变化的，如此可以将该锅底的温度真实地反应给用户，以达到精确控温的效果。本公开中，与温度传感器和燃气灶的技术方案相同的内容不再赘述。

  16. 如权利要求15所述的温度传感器，其特征在于：所述第一段和所述第三段均设置为管状结构，所述磁铁位于所述第一段的管腔内，所述干簧管位于所述第三段的管腔内。
  17. 如权利要求15或者16所述的温度传感器，其特征在于：所述第一段和所述第三段均为一端敞口另一端封闭的管状结构，所述磁铁位于所述第一段的管腔内，所述干簧管位于所述第三段的管腔内。
  18. 如权利要求15-17中任一项所述的温度传感器，其特征在于：所述第二段设置为具有弹性的弧形板，所述隔磁管卡接于所述第二段内。
  19. 一种燃气灶，包括配置成获知当前温度的温度监控组件以及配置成控制点火或熄火的控火组件，其特征在于：还包括如权利要求1-18任一所述的温度传感器，所述温度控制组件通过所述第一连接器与所述测温探头电连接，所述控火组件通过所述第二连接器与所述干簧管电连接。
  20. 一种燃气灶的温度监控和控火的方法，其特征在于，包括如下步骤：
    S1，在坐锅时，测温探头向下移动以驱使隔离管移动；
    S2，在所述隔离管移动后，所述隔离管没有挡在磁铁和干簧管之间，所述干簧管受到磁铁磁性的影响而由常开变为闭合状态，此时控火组件得电，进行点火工序；同时，测温探头触及锅底，并将检测到的温度信号传递至温度监控组件，所述温度监控组件获知当前温度信息并显示；
    S3，在移锅时，所述测温探头向上移动再次驱使隔离管移动；
    S4，在所述隔离管再次移动后，所述隔离管再次挡在磁铁和干簧管之间，所述干簧管不再受到磁铁磁性影响而由闭合状态变为常开状态，此时控火组件失电，进行熄火工序或小火工序；同时，测温探头离开锅底，不再检测温度信号，所述温度监控组件停止工作。
