具体实施方式
下面结合附图对本发明作进一步的说明。
如图1-6所示，本发明所述的一种集成传感器，包括底座1，底座1内设有传感部件，所述底座1的上端套设有与其相对独立动作的上盖14，底座1与上盖14之间设有压缩弹簧16；所述上盖14在下压行程中与底座1内的传感部件抵触联动；如图5所示，底座1固定安装在电热器皿61内且传感部件与电热器皿61主控板电连接，上盖14可上下活动地穿设于加热托盘63上，上盖14在初始状态下与底座1内的传感部件相对非接触设置，内锅62放入电热器皿61 内使上盖14下压，进而上盖14与传感部件抵触传感部件实现有锅检测，加热托盘63发热通过上盖14传导给传感部件，传感部件对内锅的温升情况进行监控并通过主控板实现过热断电保护。
如图1所示，上述底座1下端口的外缘上设有环形的安装板11，底座1的外侧套设有绝缘罩12，绝缘罩12下端与安装板11固定连接，压缩弹簧16套设于绝缘罩12和底座1之间，上盖14穿过绝缘罩12上端口与其活动连接，压缩弹簧16的上下两端分别抵设于上盖14和安装板11上；上盖14沿绝缘罩12内缘上下活动从而避免横向偏移造成的触发失效问题；所述安装板11的外缘和底面上设有适配结构从而提高装配效率，安装板11与电热器皿61连接使底座1和传感部件固定安装。
上述绝缘罩12的上端口内设有止行圈13，上盖14的下端口外缘上设有挡圈15，挡圈15的外缘直径大于止行圈13的内缘直径，压缩弹簧16的上下两端分别抵设于挡圈15和安装板11上，压缩弹簧16用于上盖14下压时提供缓冲和为上盖14弹起时提供支撑力，止行圈13与挡圈15配合限制上盖14的上行极限行程。
上述底座1上端口内设有固定板17，固定板17一侧开有缺口，所述传感部件包括热敏组件，热敏组件穿设于固定板17缺口内且热敏组件与底座1活动连接；所述固定板17上设有限制上盖14下行行程的限位块191；上盖14下压过程包括接近行程和触发行程，上盖14在初始状态下与底座1内的传感部件相对非接触设置，上盖14下压时在接近行程内抵触热敏组件，上盖13下压时进入触发行程带动热敏组件一起向下位移，触发行程结束时上盖14抵触限位块191，此时热敏组件进入温控保护模式。
上述热敏组件包括热敏电阻21和绝缘支架22，热敏电阻21与绝缘支架22 上端连接且热敏电阻21上的引线穿设于绝缘支架22上；所述绝缘支架22的上端开设有安装孔23，安装孔23下方设有结构孔24，结构孔24的直径小于安装孔23，绝缘支架22的前侧面上开有分别贯通安装孔23和结构孔24的豁口25，热敏电阻21下端嵌设于安装孔23内且热敏电阻21的引线穿设于结构孔24内；热敏电阻21通过安装孔23的嵌装结构实现快速装配，热敏电阻21的引线穿设于结构孔24内，从而在热敏电阻21或引线故障时提高替换维修效率。
所述绝缘支架22上端穿过固定板17缺口使热敏电阻21与限位块191、上盖14配合设置，绝缘支架22下端与底座1之间设有板簧26；所述底座1内横向设有隔板18将底座1的内部空间隔成上腔和下腔,隔板18上设有壁板181，绝缘支架22可上下活动地设于壁板181一侧的底座1上腔内；所述壁板181上横向设有与绝缘支架22相对的支柱182，板簧26套设于支柱182上且板簧26的上下两端分别抵设于绝缘支架22下端和隔板18上；所述固定板17缺口处的底座1上端口设有上限板184，绝缘支架22上端与上限板184抵触连接；所述板簧26为绝缘支架22提供向下缓冲力和上升支撑力，隔板18前后端的底座1内壁形成绝缘支架22的前后限位隔断，绝缘支架22在底座1内上下活动，从而在上盖14下压时保持热敏电阻22与上盖14的紧密接触连接，避免热传导断裂造成传感器故障和失去过热保护的风险。
上述传感部件还包括微动开关，微动开关固定设置在底座1内且与热敏组件联动设置，上盖14在触发行程中带动绝缘支架22下压，绝缘支架22下端设有推动杆，推动杆下端与微动开关抵触并使其输出有锅信号。
上述微动开关包括基座57、翅板51、插脚二A52、插脚二B53、触片C55和拉力弹簧56；所述插脚二A52和插脚二B53的下端分别穿过基座57的底板与基座57固定连接，插脚二A52和插脚二B53上端相对设置，插脚二B53上端横 向设有折页54；所述触片C55的固定端卡接在插脚二A52的上端，触片C55横向设置且其自由端设于折页54的下方；所述翅板51横向设置且翅板51一端与基座57铰接，拉力弹簧56的两端分别与翅板51另一端和触片C55连接，绝缘支架22的下端抵接在翅板51的另一端上；基座57固定设于底座1的下腔内，绝缘支架22下端穿过隔板18与翅板51抵触连接。
如图2所示，插脚二A52和插脚二B53组成两级端子，触片C55自由端与折页54相互接近形成接触开关，触片C55和折页54的相对面上均设有触点以提高电连接稳定性；当上盖14下压进入触发行程时，绝缘支架22推动翅板51向下转动，触片C55在拉力弹簧56的作用下产生上下跳动，触片C55自由端与折页54产生接触或分断的状态变化，使微动开关两级端子输出有锅信号；反之在上盖14复位时，在拉力弹簧56的作用下，翅板51向上反转从而使触片C55自由端与折页54产生接触或分断的状态变化，使微动开关两级端子输出无锅信号。
上述传感部件还包括过热断电装置，过热断电装置上设有与其并联的热熔断装置，所述过热断电装置和热熔断装置分别穿过固定板与上盖14对应设置。
上述过热断电装置包括插脚一A31、插脚一B32、触片A33、触片B34和陶瓷杆35，插脚一A31和插脚一B32上端设于固定板17与隔板18之间的底座1上腔中，插脚一A31、插脚一B32的下端分别穿过隔板18且与隔板18固定连接；所述触片A33的固定端与插脚一A31上端连接，触片B34的固定端与插脚一B32上端连接，触片A33的自由端与触片B34的自由端配合设置；所述陶瓷杆35穿设于固定板17上且陶瓷杆35下端抵设于触片B34自由端上，陶瓷杆35上端与上盖14配合设置。
如图2所示，设于不同高度的触片A33和触片B34的自由端上下对应形成 动作开关机构，初始状态下触片A33和触片B34呈断开设置，固定板17上设有连接在触片A33上的触发机构，触发机构在下文具体描述；上盖14进入接触行程时带动触发机构使触片A33变形，上盖14抵触限位块191终止行程时，触发机构带动触片A33抵触触片B34形成连通，此时上盖14与陶瓷杆35抵触，微动开关输出有锅信号因此插脚一A31、插脚一B32连接的主控板加热电路接通，加热托盘63工作开始对内锅62加热，内锅62的温升通过上盖14、陶瓷杆35向触片B34传导，当触片B34温升值到达形变温度时或上盖14在上升行程时，触片A33和触片B34断开连接切断主控板加热电路使加热托盘63停止加热。
上述热熔断装置包括热熔塑料制成的熔断芯41，固定板17上设有熔断孔183，熔断芯41穿设于熔断孔183内，且熔断芯41上端与上盖14配合设置；所述熔断芯41的下端与隔板18之间设有熔断弹簧42，熔断芯41下端与熔断弹簧42之间设有与过热断电装置配合的断路装置；所述断路装置包括拨叉44，拨叉44的一端与熔断弹簧42上端固定连接，拨叉44的另一端抵设于触片A33自由端的上方。
上文中过热断电装置中的触发机构同为熔断芯41，从而通过熔断芯41的过热熔断性实现过热断电装置和热熔断装置的并联保护功能；上盖14进入触发行程时，上盖14带动熔断芯41沿熔断孔183下压，熔断弹簧42向熔断芯41提供缓冲和上升支撑力，熔断弹簧42被熔断芯41下压收缩，熔断弹簧42上端的断路装置带动触片A33变形，触片A33的自由端向下与触片B34接触连通，从而激活过热断电装置的保护功能；当内锅62温升过高时，上盖14向熔断芯14传导的温度超过其熔断值，熔断芯14融化从而使熔断弹簧42向上延伸复位，断路装置同时随之上升使触片A33形变恢复断开与触片B34的连接。
上述熔断芯41上部设有小于其自身外缘直径的收口槽411，熔断芯41的温 升超过其熔断值时，收口槽411处能够更快的被熔断以提高过热保护的相应，避免快速升温下热熔断装置响应时间过长，防止造成电热器皿61整体烧坏或产生火灾隐患。
上述熔断芯41上端设有感温板43，感温板43与固定板17活动连接且感温板43与上盖14配合设置；感温板43用于限制熔断芯41的上行极限位置，装配时为了提高熔断弹簧42的缓冲力和复位支撑力，初始状态下的熔断弹簧42具有一定的压缩量，通过感温板43使熔断芯41可上下活动地装配在熔断孔183内。
上述固定板17和上盖14之间设有感温片37，感温片37与固定板17连接有弹性簧片36；所述感温片37分别与上盖14、过热断电装置和热熔断装置配合设置；如图3所示，上盖14在进入接近行程时与感温片37抵触，进而上盖14带动热敏电阻21和感温片37进入触发行程，当上盖14抵触限位块191时行程结束，此时上盖14与感温片37完全接触，感温片37则与感温板43、陶瓷杆35抵触并传导温升；感温片37和弹性簧片36可提高上盖14的触发精度以及热传导效率。
上述弹性簧片36呈横向的“U”形结构设置，弹性簧片36的下侧边与固定板17固定连接，感温片37与弹性簧片36的上侧边连接呈倾斜状设置；所述感温片37的翘起端分别与上盖14、过热断电装置和热熔断装置配合设置。，感温片37翘起端设于陶瓷杆35、感温板43的上方，且感温片37翘起端设于上盖14的下方
上述固定板17上设有卡槽171，弹性簧片36的下侧边上设有折弯插片361，折弯插片361下端插入卡槽171使弹性簧片36固定连接在固定板17上；折弯插片361和卡槽171配合连接可提高弹性簧片36和感温片37的安装和高度调 节效率。
