Description
技术领域
本发明涉及传感器技术领域,具体涉及一种新型的电压力锅压力传感器以及一种具有新型的压力传感器的电压力锅。
背景技术
电压力锅是一种市面上常见的厨房的锅具,其通过液体在较高气压下沸点会提升这一物理现象,对水施加压力,使水可以达到较高温度而不沸腾,以加快炖煮食物的效率。而每个电压力锅均具有内部可承受的最大压力值,当其内部压力超出该最大压力值就容易发生爆炸事故;以及现在家庭对用电压力锅来烹饪更美味的食物要求,故对电压力锅需要有对压力做更精准探测及控制,才可以做出更美味的美食,而现今市面上的发热盘式电压力锅一般只有机械式压力开关,只有当压力超过设置的极限时,压力开关才断开,而不能对电压力锅压力做实时检测,从而影响烹饪美味食物口感,情况严重的甚至会构成安全隐患。
发明内容
为克服上述缺陷,本发明的目的即在于提供一种新型的压力传感器以及一种具有新型的压力传感器的电压力锅。
本发明的目的是通过以下技术方案来实现的:
本发明是一种一种新型的电压力锅压力传感器,包括:本体座,所述本体座安装于固定架上,所述本体座中设有内腔体,该内腔体中设有弹性件,所述弹性件的底端与内腔体的底部相抵接,且该弹性件的顶端与探测头的底部相抵接;所述探测头上设有磁环;所述内腔体的顶部开口处设有调节上盖,且该调节上盖中设有通孔;所述探测头的顶部从该上盖的通孔穿出;所述本体座的外侧环设有环形的外腔体,所述外腔体中设有线圈,所述线圈与外部的电路相连接。
进一步,所述固定架中设有定位腔,所述本体座设置于该定位腔中,所述定位腔的底端面上设有螺孔,所述螺孔中设有与其通过螺纹相配合的调节螺杆,所述调节螺杆的顶部设有定位孔,所述本体座底部外表面设有向下凸起的卡扣,且该卡扣接入于该定位孔中卡接。
进一步,所述调节螺杆的底面设有向内凹陷的调节插孔。
进一步,所述本体座上部的外侧面上设有外螺纹,所述上盖的内侧设有与该外螺纹相配合的内螺纹。
进一步,所述本体座上设有与线圈相连接的接线片,所述固定架的侧面上设有供该接线片通过的槽体,所述接线片穿过该槽体后与外部的测量电路相连接。
进一步,所述弹性件为弹簧;所述内腔体的底部设有向上凸起的下定位柱,所述探测头的底部设有弹簧容置腔,所述弹簧容置腔的腔底上设有向下凸起的上定位柱,所述弹簧的上端和下端分别套设在该上定位柱和下定位柱上。
本发明一种具有新型的压力传感器的电压力锅,包括:内锅胆、外锅体和发热盘,以及如上所述的电压力锅压力传感器,压力传感器的固定架固定于外锅体上;且其探测头的顶部与发热盘相抵接。
本发明压力传感器固定架设置于电压力锅的外锅体外侧,探测头与发热盘底部相抵接,内锅胆食物被发热盘加热后,内部压力不断加大,内锅胆向下挤压,由于内锅胆是放置在发热盘上,这样也导致发热盘向下位移,压力越大位移越多,传感器探测到的移动距离,可根据电压力锅的压力和发热盘位移距离对应关系,即可得出锅内的实时压力值,本压力传感器可替换发热盘式电压力锅的压力开关,并且可以根据电压力锅压力值和发热盘的位移关系,准确得出压力锅的实时压力值,不仅可以提高电压力锅的安全性,更可以根据不同食物所需烹饪的压力值,实现自动调节压力,烹饪出更可口更美味的食物。
附图说明
为了易于说明,本发明由下述的较佳实施例及附图作详细描述。
图1为本发明压力传感器的分解结构示意图;
图2为本发明压力传感器的剖面结构示意图;
图3为本发明压力传感器中局部的剖面结构示意图;
图4为本发明压力传感器中的装配关系示意图;
图5为本发明电压力锅的剖面结构示意图。
具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白,以下结合附图及实施例,对本发明进一步详细说明。应当理解,此处所描述的具体实施例仅仅用以解释本发明,并不用于限定本发明。
请参阅图1至图4,本发明是一种新型的电压力锅压力传感器,包括:本体座6,所述本体座6安装于固定架8上,所述固定架8固定于外锅体外侧上;所述本体座6中设有内腔体63,该内腔体63中设有弹性件5,所述弹性件5的底端与内腔体63的底部相抵接,且该弹性件5的顶端与探测头3的底部相抵接;所述探测头3的外侧环设有磁环2;所述内腔体63的顶部开口处设有上盖1,且该上盖1中设有通孔;所述探测头3的顶部从该上盖1的通孔穿出并与电压力锅发热盘的底部相抵接;所述内腔体63的外侧环设有环形的外腔体64,所述外腔体64中设有线圈7,所述线圈7与外部的电路相连接。
进一步,所述固定架8中设有定位腔,所述本体座6设置于该定位腔中,所述定位腔的底端面上设有螺孔,所述螺孔中设有与其通过螺纹相配合的调节螺杆9,所述调节螺杆9的顶部设有定位孔91,所述本体座6底部外表面设有向下凸起的卡扣61,且该卡扣61接入于该定位孔91中卡接。旋转螺孔将改变本体座6在固定架8中的安装高度,由于在外锅体和发热盘的生产中会出现误差,每个外锅体和发热盘的外表面的平整度或弧度有可能都会存在差异,通过调整本体座6的安装高度,能保证探测头3能良好地抵接到不同发热盘的底部。
进一步,所述调节螺杆9的底面设有向内凹陷的调节插孔92。通过六角扳手等工具插入调节插孔92中并进行旋转,能实现对调节螺杆9的位置进行调整,从而调整本体座6的安装高度;并且本调节螺杆9中的调节插孔92采用向内凹陷的方式,使得调节螺杆9的底部不需要再设置凸起的螺母,从而降低了产品的整体高度,更适合于电压力锅这种整体产品体积较小的应用场合。
进一步,所述本体座6上部的外侧面上设有外螺纹,所述上盖1的内侧设有与该外螺纹相配合的内螺纹。本体座6与上盖1通过螺纹配合,其通过旋转上盖1可实现对磁环2的起始位置进行调整,将磁环2的起始位置进行调整后,即利用粘合剂将上盖1与本体座6进行固定,以完成对磁环2与线圈7的起始相对位置进行校准;即调节该上盖1时,可使产品出厂时零位达到一致。
进一步,所述本体座6上设有与线圈7相连接的接线片4,所述固定架8的侧面上设有供该接线片4通过的槽体,所述接线片4穿过该槽体后与外部的测量电路相连接。
进一步,所述弹性件5为弹簧;所述内腔体63的底部设有向上凸起的下定位柱62,所述探测头3的底部设有弹簧容置腔,所述弹簧容置腔的腔底上设有向下凸起的上定位柱31,所述弹簧的上端和下端分别套设在该上定位柱31和下定位柱62上。
请参阅图5,本发明一种具有新型的压力传感器的电压力锅,包括:内锅胆100、外锅体200和发热盘300,以及如上所述的电压力锅压力传感器400,压力传感器400的固定架8固定于外锅体200上;且其探测头3的顶部与发热盘300底部相抵接。
本发明的具体工作原理为:由于探测头3的顶部抵接在电压力锅发热盘300的底部,当内锅胆100受压膨胀而向下挤压,内锅胆100由于是放置在发热盘300上,这将也导致发热盘300向下位移,将推动探测头3向下运动;而探测头3将带动其外侧的磁环2一同向下运动,即磁环2将相对内腔体63向下运动;由于线圈7是固定于外腔体64中,故在磁环2向下运动时,其将改变进入线圈7的电感量;线圈7将采集到的电感量信号转化为电信号,输送至外部的震荡电路;再由外部的测量电路换算为压力值;当内锅胆100压力减少,发热盘300向下位移距离也减少,探测头3将在弹性件5的作用下进行回弹,使该探测头3的顶部一直抵接于发热盘300上,同时,磁环2也将往上移动,从而改变线圈7中的电感量。
以上所述仅为本发明的较佳实施例而已,并不用以限制本发明,凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等,均应包含在本发明的保护范围之内。
