本申请上述技术方案提供的导光圈，在导光圈外侧设置凸包，凸包底部设有灯孔，灯孔位置用于安装发光灯，发光灯发出的光线从灯孔内进入到导光圈内部，利用光的全反射原理，光线经过发光灯顶部照射到凸包顶部时，光会被反射，并射向导光圈的内孔侧壁，然后经导光圈的内孔侧壁反射回导光圈中，并在导光圈内进行多道反射，因此无需在导光圈的内孔侧壁上进行喷涂处理或贴反光纸，就能够实现将从导光圈的凸包顶部反射出来的光线重新反射回导光圈内部，并在导光圈内进行多道反射的目的，从而降低了材料及人工成本，并提高了批量生产时产品的生产效率；当反射的光线经导光圈底部时，光线会被反射到导光圈顶部，从而使得导光圈顶部被点亮。

具体实施方式
为了能够更清楚地理解本申请的上述目的、特征和优点，下面结合附图和具体实施方式对本申请进行进一步的详细描述。需要说明的是，在不冲突的情况下，本申请的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本申请，但是，本申请还可以采用其他不同于在此描述的方式来实施，因此，本申请的保护范围并不受下面公开的具体实施例的限制。
下面参照附图1至图56描述根据本申请一些实施例的导光圈、控制盒组件和家用电器。
如图1至图7所示，根据本申请一些实施例提供的一种导光圈1，导光圈1包括环状的本体10以及从本体10朝外侧延伸的多个凸包11，凸包11底部设有用于安装发光灯21的灯孔111。
本申请上述实施例提供的导光圈1，在导光圈1外侧设置凸包11，凸包 11底部设有灯孔111，灯孔111位置用于安装发光灯21，发光灯21发出的光线从灯孔111内进入到导光圈1内部，利用光的全反射原理，光线经过发光灯21顶部照射到凸包11顶部时，光会被反射，并射向导光圈的内孔侧壁13，然后光经导光圈的内孔侧壁13反射回导光圈1中，并在导光圈1内进行多道反射，因此无需在导光圈的内孔侧壁13上进行喷涂处理或贴反光纸，就能够实现将从导光圈1凸包11顶部反射出来的光线重新反射回导光圈1内部，并在导光圈1内进行多道反射的目的，从而降低了材料及人工成本，并提高了批量生产时产品的生产效率；当反射的光线经导光圈1底部时，光线会被反射到导光圈的顶部面14，从而使得导光圈的顶部面14被点亮。
在一个实施例中，如图1所示，凸包11顶部设有两个斜面112，两个斜面112围成一条凹槽，确保灯光能射入左右两侧，并经斜面后射向导光圈的内孔侧壁13。
在一个实施例中，如图6和图7所示，两个斜面112的交线113与导光圈1的中心轴或导光圈1中心轴的平行线相交，且夹角在30°～60°范围内，两个斜面112的交线113与导光圈1的中心轴或导光圈1中心轴的平行线所确定的平面与每一斜面112的夹角在30°～60°范围内。
需要说明的是，两个斜面112的交线113，或称为，两个斜面112的夹线，即：两个斜面112相交形成的交线，更具体来说，两个斜面112相交，两个斜面112的相交线。
如图6所示，图示中的α表示两个斜面112的交线113与导光圈1的中心轴(或导光圈1中心轴的平行线)的夹角，30°≤α≤60°。
如图7所示，图示中的β表示两个斜面112的交线113和导光圈1中心轴(或导光圈1中心轴的平行线)所确定的平面与其中一斜面112的夹角，γ表示两个斜面112的交线113和导光圈1中心轴(或导光圈1中心轴的平行线)所确定的平面与另一斜面112的夹角，30°≤β≤60°，30°≤γ≤60°。
换言之，垂直于两个斜面112做剖面(如图6所示C-C向做剖面)，在剖面与斜面112的连接处形成两条相交于一交点的斜线(如图7所示位于β和γ两侧的两条斜线)，每一斜线与过该交点且平行于导光圈1中心轴的直线(如图7所示位于β和γ之间的一条直线)之间的夹角在30°～60°范围内，即 30°≤β≤60°，30°≤γ≤60°。
通过合理设计凸包顶部的两个斜面的倾斜角度，使得安装于凸包底部的灯孔中的发光灯21发出的光线从灯孔111内进入到导光圈1内部，利用光的全反射原理，光线经过发光灯21顶部的两个斜面112时，光会被反射，因这两个斜面112的每个斜面112都有两个方向的角度，所以光在射到该斜面112上后，光不是只朝着导光圈1中心方向射，而是与中心方向倾斜一定角度射向导光圈的内孔侧壁13，因光不是直接射向导光圈的内孔侧壁13，所以光能经内孔侧壁反射回导光圈1中，并在导光圈1内进行多道反射，因此无需在导光圈的内孔侧壁13上进行喷涂处理或贴反光纸，就能够实现将从导光圈1凸包11顶部斜面112反射出来的光线重新反射回导光圈1内部，并在导光圈1内进行多道反射的目的，从而降低了材料及人工成本，并提高了批量生产时产品的生产效率；当反射的光线经导光圈1底部的齿条12时，光线会被齿条12斜面反射到导光圈顶部，从而使得导光圈的顶部面14被点亮，确保导光圈1顶部被点亮的均匀性。
在一个实施例中，两个斜面112的交线113在垂直于导光圈1的中心轴的面上做投影形成的投影线与位于交线113下方的灯孔111中心轴的距离和发光灯21的直径之比在0～2/3范围内。
为了保证发光灯21发出的光线能够均等地射入交线113两侧的斜面112，设计两个斜面112的交线113在垂直于导光圈1中心轴的面上做投影形成的投影线正好落在位于交线113下方的灯孔111中心轴上，或者偏离位于交线113下方的灯孔111中心轴不超过发光灯21的直径的2/3。
具体而言，发光灯21可以为灯柱或贴片灯等各种发光灯21，对于灯孔111为灯柱孔，在灯柱孔中安装灯柱的方案，也可以利用灯柱的直径来进行限定，两个斜面112的交线113在垂直于导光圈1中心轴的面上做投影形成的投影线与位于交线113下方的灯柱中心轴的距离与灯柱直径之比在0～2/3范围内，在一个实施例中，在0～1/2范围内。
在一个实施例中，如图2和图5所示，多个凸包11沿本体10的周向间隔设置，每一凸包11的顶部均设有两个斜面112，两个斜面112的交线113的延长线均相交于导光圈1中心轴上的同一点。上述设计以确保多个凸包11顶部 两个斜面112的交线113的延长线均与导光圈1中心轴相交且两者夹角均相等，也即确保多个斜面112在沿导光圈1中心轴方向的倾斜角度均相等。
在一个实施例中，如图2和图5所示，两个斜面112关于两个斜面112的交线113左右对称设置。上述设计以确保两个斜面112的交线113和导光圈1中心轴(或导光圈1中心轴的平行线)所确定的平面与其中一斜面112的夹角等于与另一斜面112的夹角。
一个具体实施例中，如图1、图2和图5所示，凸包11的数量为三个，三个凸包11沿导光圈1侧壁的周向均匀布置，在一个实施例中，导光圈1以其中心轴为旋转中心旋转对称，也即整个导光圈1设计为旋转对称结构。
在一个实施例中，如图3和图4所示，本体10的底部设有齿条12，斜面112的最高点位置高于齿条12最高点位置的齿的高度。上述设计以确保光线经导光圈1凸包11顶部的斜面112反射后，光线能射到最高点位置的齿上，从而确保光线能够经每一齿的斜面112反射到导光圈的顶部面14，将导光圈的顶部面14点亮。
在一个实施例中，如图1、图3、图4、图6和图7所示，导光圈1外侧沿周向间隔设有多个凸包11，齿条12的齿沿周向分为与凸包11等数量且对应设置的多组，每组齿的高度由与该组齿对应的凸包11的两侧向靠近凸包11的灯孔111中心轴的位置逐渐降低，位于凸包11顶部的斜面112的最高点位置高于该组齿中最远离灯孔111中心轴的位置的齿的高度。
如图4所示，位于凸包11顶部的斜面112的最高点位置高于该组齿中最远离灯孔111中心轴的位置的齿的高度，即H1＞0。
为确保光线经导光圈1凸包11顶部的斜面112反射后，光线能射到距发光灯21最远的齿的斜面112上，所以导光圈1凸包11顶部的斜面112的最高点应高于导光圈1底部与凸包11对应的该组齿中，最远离发光灯21的位置的齿的高度。
在一个具体实施例中，如图1至图7所示，在导光圈1外侧设计一个或多个凸包11，凸包11底部设计有灯柱孔，产品装配完成后，灯柱插装在该灯柱孔中，在灯柱孔顶部设计有两个斜面112，该两个斜面112间围成一条凹槽，该两个斜面112的交线113与导光圈1中心轴的夹角为30°～60°范围内，即 30°≤α≤60°；为保证灯光能均等射入左右两侧的斜面112，该两个斜面112的交线113在垂直于导光圈1中心轴的面上做投影形成的投影线与位于交线113下方的灯柱中心轴的距离与灯柱直径之比在0～2/3范围内；若垂直两个斜面112做剖面，在该剖面与斜面112的连接处形成两条相交于一交点的斜线，每一斜线与过该交点且平行于导光圈1中心轴的直线之间的夹角在30°～60°范围内，即30°≤β≤60°，30°≤γ≤60°；为确保灯光经导光圈1凸包11顶部的斜面112反射后，灯光能射到距灯柱最远的齿的斜面112，所以导光圈1凸包11顶部的斜面112的最高点高于导光圈1底部齿条12中最远离灯的位置的齿的高度，即H1＞0。
具体地，灯光从灯柱孔内进入到导光圈1内部，利用光的全反射原理，光经过灯柱顶部的两个斜面112时，光会被反射，因这两个斜面112的每个斜面112都有两个方向的角度，所以光在射到该斜面112上后，光不是只朝着导光圈1中心方向射，而是与中心方向倾斜一定角度射向导光圈的内孔侧壁13，因光不是直接射向导光圈的内孔侧壁13，所以光能经导光圈的内孔侧壁13反射回导光圈1中，并在导光圈1内进行多道反射，当反射的光经导光圈1底部的齿条12时，光线会被齿条12斜面反射到导光圈的顶部，从而使得导光圈的顶部面14被点亮；为确保灯光经导光圈1凸包11顶部的斜面112反射后，灯光能射到距灯柱最远的齿的斜面112，所以导光圈1凸包11顶部的斜面112的最高点应高于导光圈1底部齿条12中最远离灯柱的位置的齿的高度；通过上述设计无需对导光圈的内孔侧壁13进行喷涂处理或贴反光纸，因而降低了产品成本的同时，也提高了在批量生产时的生产效率。
如图8至图56所示，本申请第二方面的实施例提供了一种控制盒组件，包括：线路板2、如上述任一实施例的导光圈1、控制盒6和旋钮4，线路板2上设有发光灯21；发光灯21对应插装在导光圈1的灯孔111中；控制盒6装设于导光圈1顶部，控制盒6上开设有旋钮孔61；旋钮4装设于旋钮孔61处。
本申请上述实施例提供的控制盒组件，因其包括上述任一实施例的导光圈1，因而具有上述任一实施例的导光圈1的有益效果，在此不再赘述。
应当理解的是，将导光圈1设于旋钮4的外侧，从而可以在导光圈1底部的发光灯21被点亮时，在旋钮4的外侧形成一个亮圈，从而提升产品的科技 感和炫酷感。
实施例一：
如图8至图16所示，控制盒组件包括：线路板2、导光圈1和线路板支架3，线路板2上设有发光灯21；线路板支架3装设于线路板2上，线路板支架3上设有与发光灯21对应的通孔31，导光圈1安装于线路板支架3上，发光灯21穿过通孔31后插装在导光圈1的灯孔111中。利用线路板支架3实现导光圈1在线路板2上的固定，结构简单，装配方便。
在一个实施例中，如图8、图11、图13至图16所示，线路板支架3上设有挡光筋32，挡光筋32靠近导光圈1的凸包11设置且位于导光圈1的内侧，挡光筋32与导光圈的内孔侧壁13之间的距离小于1mm，且挡光筋32的高度高于发光灯21的顶部面。
如图16所示，挡光筋32与导光圈的内孔侧壁13之间的距离小于1mm，即D1＜1mm；挡光筋32的高度高于发光灯21的顶部面，即H2＞0。
在线路板支架3上靠近导光圈的内孔侧壁13的位置，且靠近导光圈1装发光灯21的凸包11位置各设计一挡光筋32，并设计挡光筋32与导光圈的内孔侧壁13之间的距离小于1mm，该挡光筋32因与导光圈的内孔侧壁13的距离小，且挡光筋32的高度高于发光灯21的顶部面，所以即使有光射到导光圈1与该挡光筋32的缝隙中，用户也难以看到该处位置的亮光，也即不至于从控制盒6与旋钮4的缝隙中看到导光圈1有发光灯21的位置过亮。
在一个实施例中，如图9至图12所示，控制盒6的顶部表面覆有膜62，膜62由控制盒6的顶部表面延展至旋钮孔61的顶部侧壁处，延展至旋钮孔61的顶部侧壁处的膜62的高度大于1mm、且被印刷成不透明颜色。
如图12所示，延展至旋钮孔61的顶部侧壁处的膜62的高度大于1mm，即H3＞1mm。
在控制盒6的顶部表面覆膜62(如PET膜)，并使得膜62卷了一段到控制盒6的旋钮孔61中，具体地，延展至旋钮孔61的顶部侧壁处的膜62的高度大于1mm，且该膜62被印刷成非透明颜色，所以导光圈顶部的光在穿过控制盒6顶部时，光线能将控制盒6顶部的膜62没有印刷的一圈点亮，也即为实现被发光灯21点亮的导光圈1能够透过控制盒6显示出来，可以在控制盒 6上设置与导光圈1的顶部面对应的透光区域，因旋钮孔61内一段膜62(被印刷成非透明颜色)的阻挡，光线无法从控制盒6旋钮孔61的侧壁射到控制盒6与旋钮4的缝隙中，从而实现仅控制盒6顶部绕旋钮4一圈没有印刷的部分被点亮，控制盒6与旋钮4的缝隙中无亮光或亮光非常弱，从而很好地解决了现有方案中亮光不均匀的问题。
进一步地，为了防止用户在用湿抹布擦拭操控部分表面时，导致湿抹布上的水从控制盒6和旋钮4之间的缝隙进入到线路板2处，在控制盒6顶部设置一环形的挡水槽63，旋钮4的外圈插装在挡水槽63中；在此结构基础上，可以将覆于控制盒6顶部表面的膜62从控制盒6的顶部表面延展至挡水槽63的外圈内槽壁处，且设计延展至挡水槽63的外圈内槽壁处的膜62的高度大于1mm、且被印刷成不透明颜色。
具体而言，现有的控制盒6采用IMD工艺制作，即透明材料顶部覆有一层有印刷内容的PET膜62，为使得导光圈1的顶部的光能显示出来，在控制盒6装旋钮4的旋钮孔61的位置，将PET膜62留一圈不印刷，也即为实现被发光灯21点亮的导光圈1能够透过控制盒6显示出来，可以在控制盒6上设置与导光圈1的顶部面对应的透光区域；为节省产品成本，通常不会在导光圈1底部设计一圈灯来点亮导光圈的顶部面14，而是根据导光圈1实际大小，在导光圈1底部布置一个或合理布置少量的的LED灯来点亮导光圈的顶部面14。为避免灯光过多地从导光圈的顶部面14靠近灯的位置射出，导致导光圈的顶部面14靠近灯的位置亮度过亮，远离灯的位置亮度过暗，所以灯不会设计在导光圈1的正下方，而是导光圈1外侧设计有凸包11，灯设计在凸包11下方，另外在导光圈1底部设计有齿条12，齿条12的齿的高度从靠近灯的位置开始逐步升高，且每个齿都有一个面的角度为30度到60度，使得射到该面上的光能反射到导光圈的顶部面14。然而现有方案中不可避免的会有一部分光从导光圈1内孔内靠近灯的内侧壁射出。从而导致在旋钮4与控制盒6之间的缝隙中，靠近灯的位置的亮度最亮。为解决该问题常会在导光圈的内孔侧壁13靠近灯的位置贴上反光膜62或反光漆，从而使得在增加材料成本同时，也因多一道工序会导致生产效率下降，另外即使在导光圈1内侧壁贴有反光膜62或涂有反光漆，导光圈的顶部面14的光仍会将控制盒6与旋钮4的缝隙的 顶部点亮，且该缝隙中亮度明显弱于导光圈1正上方的亮度，所以从旋钮4正上方看时，会看到亮光区域的亮度不均匀，该效果严重影响产品的外观效果，降低产品的档次。
在一个具体实施例中，如图8至图16所示，在线路板支架3上靠近导光圈的内孔侧壁13的位置，且靠近导光圈1的装灯的凸包11位置各设计一挡光筋32，该挡光筋32与导光圈内孔侧壁13的距离D1小于1mm，即D1＜1mm，装配完成后，该挡光筋32的高度高于导光圈1底部灯柱顶部面，即H2>0，该挡光筋32因与导光圈内孔侧壁13距离小，所以即使有光射到导光圈1与该挡光筋32的缝隙中，用户也难以看到该处位置的亮光，即不至于从控制盒6与旋钮4的缝隙中看到导光圈1有灯的位置过亮；另外将控制盒6顶部的PET膜62卷一部分到装旋钮4的旋钮孔61中，卷到旋钮孔61中的膜62的高度H3大于1mm，即H3＞1mm，且该卷入旋钮孔61中的膜62需印刷成非透明颜色，因控制盒6的覆膜62卷了一段到控制盒6的旋钮孔61中，且该膜62已印刷成非透明颜色，所以导光圈的顶部面14的光在穿过控制盒6顶部时，光线能将控制盒6顶部的PET膜62没有印刷的一圈点亮，因旋钮孔61内一段PET膜62(该膜62已印刷成非透明颜色)的阻挡，光线无法从控制盒6旋钮孔61的侧壁射到控制盒6与旋钮4的缝隙中。
上述方案，在满足产品性能前提下，取消了导光圈1内侧的贴反光膜62或涂反光漆，降低了产品成本，提高了产品的生产效率，且该方案很好解决了现有方案中控制盒6与旋钮4间有亮光的问题，上述方案仅控制盒6顶部绕旋钮4一圈没有印刷的部分会被点亮，控制盒6与旋钮4的缝隙中无亮光或亮光非常弱，从而解决了现有方案中亮光不均匀的问题，提升了产品的显示效果。
在一些实施例中，如图17至图48所示，控制盒组件包括：按键固定座7(或7')和按键支架8(或8')，按键固定座7(或7')装设于线路板2上；按键支架8(或8')装设于按键固定座7(或7')上，按键固定座7(或7')和按键支架8(或8')中的一个上装设有按键柱子71(或81')、另一个上设有供按键柱子71(或81')穿过的导向限位孔81(或71')。
在一些实施例中，如图17至图48所示，控制盒组件包括：线路板2、按键固定座7(或7')、按键支架8(或8')和控制面板9，具体地，线路板2上 设有线路板按键22；按键固定座7(或7')固定于线路板2上，按键支架8(或8')装设于按键固定座7(或7')上，按键固定座7(或7')和按键支架8(或8')中的一个上装设有按键柱子71(或81')、另一个上设有供按键柱子71(或81')穿过的导向限位孔81(或71')；控制面板9装设于按键固定座7(或7')及按键支架8(或8')顶部，控制面板9上设有与线路板按键22对应的按键标识91，按键柱子71(或81')位于按键标识91和线路板按键22之间，按键标识91被按压时能够带动按键柱子71(或81')按压线路板按键22。
利用导向限位孔限制按键柱子发生较大幅度摆动，这样即使当按键柱子很长时，在按动控制面板上的按键标识91(如按键凸包)时，按键柱子也不会有很大歪斜，始终被限位于导向限位孔中，使得按压按键标识91时，按键标识91能够通过按键柱子精准地压在线路板按键22上，从而保证了产品工作的可靠性，很好地解决了现有方案中因按键柱子过长，按键柱子容易歪斜而导致按键失效的问题。
通过按压控制面板9上的按键标识91，带动按键固定座7(或按键支架8')上的按键柱子71(或81')移动，按键柱子71(或81')将按压力传递给线路板2上的线路板按键22，从而实现对产品的控制；具体地，按键标识91为具有标识的功能键，如煮汤、煮粥等标识，为了提高按压手感，按键标识91处通常设置为提高按压手感的凸包，当然，按键标识91也可不凸起来，具体可以根据实际产品情况进行合理设计。
在一些实施例中，如图17和图33所示，按键固定座7(或7')和按键支架8(或8')装设于导光圈1的内侧区域。
实施例二：
如图17至图32所示，控制盒组件包括：按键固定座7和按键支架8，按键固定座7装设于线路板2上；按键支架8装设于按键固定座7上，按键固定座7上装设有按键柱子71，按键支架8上设有供按键柱子71穿过的导向限位孔81。一个实施例中，按键柱子71通过连接于按键固定座7上的弹性筋72与按键固定座7相连，按键柱子71的顶部从导向限位孔81伸出。
在该方案中，将现有按键支架8的按键部分的结构设计在按键固定座7上，具体地，按键柱子71通过连接于按键固定座7上的弹性筋72与按键固定 座7相连，使得在按压作用下按键柱子71能够发生轴向移动并向线路板按键22传递按压力；另外再设计一按键支架8，按键支架8装设于按键固定座7顶部，并在按键支架8上设置供按键柱子71的顶部伸出的导向限位孔81，该导向限位孔81能够避免按键柱子71沿周向发生歪斜，使得按压按键标识91时，按键标识91能够通过按键柱子71精准地压在线路板按键22上，从而保证了产品工作的可靠性。
一个实施例中，如图29至图32所示，按键柱子71的顶部端面到弹性筋72的顶部端面的距离与按键柱子71的总长度之比在1/4～3/4范围内。如图31所示，图示中的L1表示按键柱子71的顶部端面到弹性筋72的顶部端面的距离，图示中的L2表示按键柱子71的总长度。
因按键柱子71与按键固定座7之间仅通过弹性筋72相连，所以该弹性筋72是按键柱子71摆动的支点位置，当按键柱子71摆动相同角度时，按键柱子71端部距离弹性筋72支点越远，按键柱子71摆动后按键柱子71端部偏离线路板按键22中心距离越远，反之则越近。现有按键结构当按键柱子71较长时，按键柱子71底部距离弹性筋72支点很远，所以按动控制面板9上的按键标识91时，按键柱子71顶部摆动较小，而远离支点位置的按键柱子71底部摆动会很大，致使按键柱子71底部端面极易偏离线路板按键22，导致按键柱子71无法压住线路板按键22从而导致按键失效；在本申请的上述方案中，设计按键柱子71的顶部端面到弹性筋72的顶部端面的距离与按键柱子71的总长度之比在1/4～3/4范围内，也即将弹性筋72设置在按键柱子71总长度的中间位置或靠近中间位置，这样可以确保按键柱子71顶部和按键柱子71底部的歪斜量大致相等或者歪斜量差值不会太大，从而减小按压按键标识91时可能造成的按键柱子71的歪斜程度，进而确保按键的可靠性。
一个实施例中，如图26至图28所示，导向限位孔81的孔径大于按键柱子71的直径，且导向限位孔81的孔径与按键柱子71的直径的差值在0.4mm～6mm范围内。如图28所示，图示中的d1为导向限位孔81孔壁距离按键柱子71的外侧面的距离，0.2mm≤d1≤3mm。
按键支架8装配在按键固定座7顶部，装配完成后，按键固定座7上的按键柱子71的顶部从按键支架8上的导向限位孔81中伸出，导向限位孔81孔 壁距离按键柱子71的外侧面的单边间隙在0.2mm～3mm范围内，既避免间隙过小导致按键柱子71无法顺利插入导向限位孔81中的问题，又避免间隙过大导致导向限位孔81对按键柱子71的限位作用差、无法很好地限制按键柱子71摆动的问题。
一个实施例中，如图18、图20和图27所示，按键支架8顶部设有导向限位孔81的位置设有沉孔82，导向限位孔81设于沉孔82的底部且贯通沉孔82的底壁，沉孔82的深度大于0.3mm，沉孔82的直径大于4mm，如图27所示，图示中的h表示沉孔82的深度，d2表示沉孔82的直径，h＞0.3mm，d2＞4mm。
在按键支架8顶部的导向限位孔81位置设计一沉孔82，沉孔82深度大于0.3mm，沉孔82直径大于4mm，从而确保了按键标识91按到控制面板9底部面以下位置时按键标识91仍能按动，从而保证了按键的手感不受影响。
在一个实施例中，如图17至图32所示，控制盒组件包括：线路板2、按键固定座7、按键支架8和控制面板9，线路板2上设有线路板按键22；按键固定座7固定于线路板2上，按键支架8装设于按键固定座上，按键固定座7上装设有按键柱子71，按键支架8上设有供按键柱子71穿过的导向限位孔81；控制面板9装设于按键固定座7及按键支架8顶部，控制面板9上设有与线路板按键22对应的按键标识91，按键柱子71位于按键标识91和线路板按键22之间，按键标识91被按压时能够带动按键柱子71按压线路板按键22。
通过按压控制面板9上的按键标识91，带动按键固定座7上的按键柱子71移动，按键柱子71将按压力传递给线路板2上的线路板按键22，从而实现对产品的控制；具体地，按键标识91为具有标识的功能键，如煮汤、煮粥等标识，为了提高按压手感，按键标识91处通常设置为提高按压手感的凸包，当然，按键标识91也可不凸起来，具体可以根据实际产品情况进行合理设计。
在一个实施例中，如图28所示，按键支架8上设有卡扣83，按键支架8通过卡扣83扣合在线路板2上，卡扣83的扣合面为向远离线路板2的板面方向延伸的斜面。现有方案中按键支架8扣合在线路板2上的卡扣83的顶部是平面，在装配时，容易出现按键支架8尺寸不稳定的情况，当按键支架8尺寸偏小时，按键支架8的扣位扣不到线路板2上，当按键支架8尺寸偏大时，按 键支架8的卡扣83距离线路板2距离过大，导致按键虚位；本申请的上述方案将按键支架8的卡扣83的顶部面(即扣合面)设计成斜面，即卡扣83顶部非水平面，这样不管按键支架8尺寸偏大或偏小，按键支架8始终都能稳定扣合在线路板2上，只是线路板2同卡扣83顶部面的接触位置不一样，但都能稳定扣住线路板2，从而避免了按键容易虚位及按键支架8扣不到位的问题。
在一个实施例中，如图18和图21所示，线路板2上装设有编码器23，编码器23包括编码器内圈231和编码器外圈232，编码器内圈231与线路板2固定连接、编码器外圈232能够相对线路板2旋转，编码器外圈232固定装设有中部带孔的旋钮4，也即旋钮4的中部开孔，旋钮4与编码器外圈232固定连接，按键固定座7及按键支架8均设于旋钮4的中部孔中。
上述方案能够实现旋钮4旋转，并通过转动旋钮4控制编码器23动作；且能够实现旋钮4中部孔内的按键支架8固定不动，并可以通过操作按键支架8顶部的控制面板9上的按键标识91对产品进行控制。
在一个实施例中，如图23所示，按键固定座7固定于编码器内圈231或线路板2上，按键支架8固定于编码器内圈231或线路板2上，按键支架8和按键固定座7中的一个上设有导向筋84或导向柱，另一个上设有与导向筋84或导向柱相配合的导向槽73或导向孔。
现有的按键结构，为了避免用户在用湿抹布拭檫产品的控制面板9时，水从按键支架8与旋钮4的缝隙中进入到控制盒6内部从而导致装配在控制盒6内的线路板2故障，通常会在旋钮4的中部孔中设计有挡水筋，该挡水筋处于按键支架8底部，也就导致按键支架8的顶部面直径大于旋钮4中部孔中挡水筋的直径，所以在装配时，只能先装配旋钮4，然后从旋钮4顶部装配按键支架8，使得按键支架8扣合在线路板2上或旋钮4中部孔内圈的侧壁的扣位上；进一步地为便于用户用手抓握旋钮4进行操作，旋钮4通常不会做太大，且高度会设计得偏高，所以旋钮4中部孔直径会较小，且旋钮4顶部面距离线路板2的距离会比较远。在现有方案中，按键支架8仅为一个零件，装配时，因按键支架8无法做大的导向，所以装配时只能通过贴在按键支架8顶部的控制面板9的印刷内容或控制面板9的限位点粗略判断该零件的装配方向，即凭感觉找到大概的装配方向，也即盲装，现有方案在批量生产时，无法保证每个按键 支架8都能一次性插装到位，严重影响生产效率；在本申请的上述方案中，在按键支架8上设计导向筋84或导向柱，在按键固定座7上设计与导向槽73或导向孔(亦可在按键支架8上设计导向槽73或导向孔，在按键支架8上设计导向筋84或导向柱)，装配时，将按键支架8的导向筋84或导向柱对应插入按键固定座7上的导向槽73或导向孔中，使得按键支架8上的扣位能准确扣合在线路板2上或编码器23中部孔的内侧壁上，使得按键支架8的装配更方便。
一个具体实施例中，如图19和图20所示，按键支架8上设有导向筋84或导向柱，按键固定座7上设有导向槽73或导向孔，导向槽73或导向孔的顶部凸出编码器23的顶部端面。
在按键固定座7上设计与按键支架8上的导向筋84或导向柱相配合的导向槽73或导向孔，且该导向槽73或导向孔的高度较高，具体地，导向槽73或导向孔的顶部凸出编码器23的顶部端面，即导向槽73或导向孔顶部高度高于编码器23最顶端位置高度，可选地在导向槽73或导向孔顶部设计有大斜角或大圆角等导向结构，在装配按键支架8时，按键支架8的导向筋84或导向柱很容易塞入到按键固定座7的导向槽73或导向孔中，另外因按键固定座7的导向槽73或导向孔高度较高，所以在装配按键支架8时，在按键支架8顶部还没装配到旋钮4顶部面以下前，装配人员可以通过按键支架8与旋钮4的缝隙中轻易看到按键支架8与按键固定座7的导向结构是否已配合；配合到位后，仅需往下按压按键支架8顶部，即可准确无误地将按键支架8插装到位，使得按键支架8上的扣位能准确扣合在线路板2上或编码器23中部孔的内侧壁上，从而使得按键支架8的装配更方便，有利于提高生产效率。
在一个实施例中，如图17和图18所示，控制盒组件包括控制盒后盖5，控制盒后盖5上设置容置槽51，线路板2安装在容置槽51中，控制盒6盖装在控制盒后盖5上且与控制盒后盖5固定连接，从而将控制盒组件上的各部件装配在一起形成一个组件。
在一个具体实施例中，如图17至图32所示，线路板2上装有中心有孔且内圈固定在线路板2上而外圈可旋转的圆环形大编码器23，在编码器23中部孔内设计线路板按键22，且控制面板9距离线路板2的距离大于20mm，设计 一按键固定座7，将按键结构中按键柱子71及按键的弹性筋72都设计在该按键固定座7上，按键固定座7上的按键柱子71顶部跟按键的弹性筋72顶部端面的距离L1为按键柱子71总长度L2的1/4到3/4，装配时，可将按键固定座7固定在编码器内圈231上，也可将之扣合在线路板2上；另外在按键固定座7顶部设计一按键支架8，按键支架8既可扣在线路板2上，也可扣在固定座上，还可扣在编码器内圈231上，在按键支架8上设计有供按键柱子71穿过的导向限位孔81，装配完成后，按键柱子71的外侧面与导向限位孔81的孔壁之间的单侧距离d1为0.2mm到3mm；在按键支架8顶部导向限位孔81位置设计一沉孔82，沉孔82深度h大于0.3mm，沉孔82直径d2大于4mm，从而确保了按键标识91按到控制面板9底部面以下位置时按键标识91仍能按动，进而保证了按键的手感不受影响。
具体装配时，如图22至图25所示，按键固定座7上设计有扣位，装配时，先将按键固定座7通过扣位扣合在编码器内圈231的扣位上(或者扣合在位于编码器内圈231内侧的线路板2上)；按键支架8上设计有扣位，装配时，将按键支架8的扣位扣装在按键固定座7上或将该扣位伸过按键固定座7直接扣合在线路板2上；按键支架8上设计有导向限位孔81，装配完成后，按键固定座7上的按键柱子71顶部从按键支架8的导向限位孔81内伸出，此时按键柱子71顶部距离按键支架8顶部面距离为0到1.5mm，按键柱子71外侧面与导向限位孔81孔壁之间的距离为0.2mm到3mm，最后在固定支架顶部贴上控制面板9，即完成按键部分的装配。
实施例三：
如图33至图48所示，控制盒组件包括：按键固定座7'和按键支架8'，按键固定座7'装设于线路板2上；按键支架8'装设于按键固定座7'上，按键支架8'上装设有按键柱子81'，按键固定座7'上设有供按键柱子81'穿过的导向限位孔71'。一个实施例中，按键柱子81'通过连接于按键支架8'上的弹性筋82'与按键支架8'相连，按键柱子81'的底部从导向限位孔71'伸出。
在该方案中，将现有按键支架8'的按键部分的结构设计在按键支架8'上，具体地，按键柱子81'通过连接于按键支架8'上的弹性筋82'与按键支架8'相连，使得在按压作用下按键柱子81'能够发生轴向移动并向线路板按键22传递按压 力；另外再设计一按键固定座7'，按键支架8'装设于按键固定座7'顶部，在按键固定座7'上设置供按键柱子81'的底部伸出的导向限位孔71'，按键柱子81'的底端伸出导向限位孔71'向线路板按键22传递按压力，该导向限位孔71'能够避免按键柱子81'沿周向发生歪斜，使得按压按键标识91时，按键标识91能够通过按键柱子81'精准地压在线路板按键22上，从而保证了产品工作的可靠性。
一个实施例中，如图44至图46所示，导向限位孔71'的顶部设有向外扩展的斜角711'或圆角，以形成引导按键柱子81'插入导向限位孔71'的导向面。
在导向限位孔71'的顶部设计斜角711'或圆角，以引导按键柱子81'顺利插入导向限位孔71'中，利于按键支架8'顺利装配到按键固定座7'顶部；可选地斜角宽度大于0.5mm。
一个实施例中，导向限位孔71'的孔径大于按键柱子81'的直径，且导向限位孔71'的孔径与按键柱子81'的直径的差值在0.4mm～6mm范围内。如图44所示，图示中的d3为导向限位孔71'孔壁距离按键柱子81'的外侧面的距离，0.2mm≤d3≤3mm。
按键支架8'装配在按键固定座7'顶部，装配完成后，按键支架8'上的按键柱子81'的底部从按键固定座7'上的导向限位孔71'中伸出，导向限位孔71'孔壁距离按键柱子81'的外侧面的单边间隙在0.2mm～3mm范围内，既避免间隙过小导致按键柱子81'无法顺利插入导向限位孔71'中的问题，又避免间隙过大导致导向限位孔71'对按键柱子81'的限位作用差、无法很好地限制按键柱子81'摆动的问题。
在一个实施例中，如图33至图48所示，控制盒组件包括：线路板2、按键固定座7'、按键支架8'和控制面板9，线路板2上设有线路板按键22；按键固定座7'固定于线路板2上，按键支架8'装设于按键固定座7'上，按键支架8'上装设有按键柱子81'，按键固定座7'上设有供按键柱子81'穿过的导向限位孔71'；控制面板9装设于按键固定座7'及按键支架8'顶部，控制面板9上设有与线路板按键22对应的按键标识91，按键柱子81'位于按键标识91和线路板按键22之间，按键标识91被按压时能够带动按键柱子81'按压线路板按键22。
通过按压控制面板9上的按键标识91，带动按键支架8'上的按键柱子81' 移动，按键柱子81'将按压力传递给线路板2上的线路板按键22，从而实现对产品的控制；具体地，按键标识91为具有标识的功能键，如煮汤、煮粥等标识，为了提高按压手感，按键标识91处通常设置为提高按压手感的凸包，当然，按键标识91也可不凸起来，具体可以根据实际产品情况进行合理设计。
在一个实施例中，如图44和图47所示，按键支架8'上设有卡扣83'，按键支架8'通过卡扣83'扣合在线路板2上，卡扣83'的扣合面为向远离线路板2的板面方向延伸的斜面。
将按键支架8'直接扣合在线路板2上，现有方案中按键支架8'扣合在线路板2上的卡扣83'的顶部是平面，在装配时，容易出现按键支架8'尺寸不稳定的情况，当按键支架8'尺寸偏小时，按键支架8'的扣位扣不到线路板2上，当按键支架8'尺寸偏大时，按键支架8'的卡扣83'距离线路板2距离过大，导致按键虚位；本申请的上述方案将按键支架8'的卡扣83'的顶部面(即扣合面)设计成斜面，即卡扣83'顶部非水平面，这样不管按键支架8'尺寸偏大或偏小，按键支架8'始终都能稳定扣合在线路板2上，只是线路板2同卡扣83'顶部面的接触位置不一样，但都能稳定扣住线路板2，从而避免了按键容易虚位及按键支架8'扣不到位的问题。
一个具体实施例中，如图33至图48所示，按键支架8'上设计有按键柱子81'，按键固定座7'上设计有供按键柱子81'顶部穿过的导向限位孔71'，导向限位孔71'顶部设计有斜角711'或圆角，斜角宽度大于0.5mm，装配时，先将按键固定座7'通过扣位扣合在编码器23中部孔的内侧壁或扣合在线路板2上，按键固定座7'也可不通过扣位固定而直接放在编码器23中部孔中，只通过编码器23内侧壁的筋位进行前后左右限位，或在固定柱上设计筋或柱子插装在线路板2上进行前后左右限位；将按键柱子81'设计在按键支架8'上，按键支架8'装配在按键固定座7'顶部，具体地，按键支架8'既可扣在线路板2上，也可扣在固定座上，还可扣在编码器内圈231上，装配完成后，按键支架8'的按键柱子81'插装在按键固定座7'的导向限位孔71'中，按键固定座7'的导向限位孔71'的孔壁距离按键柱子81'的外侧壁的单边间隙d3为0.2mm～3mm；可选地，按键支架8'扣合在线路板2上，且按键支架8'扣合在线路板2上的卡扣83'为斜面扣，即扣位顶部非水平，以确保不管按键支架8'尺寸偏大或偏小，按键支 架8'始终都能稳定扣合在线路板2上，从而既解决了按键柱子81'容易歪斜导致按键失效的问题，也进一步优化了按键支架8'容易虚位及按键支架8'扣不到位的问题。
在一些实施例中，如图34和图37所示，线路板2上装设有编码器23，编码器23包括编码器内圈231和编码器外圈232，编码器内圈231与线路板2固定连接、编码器外圈232能够相对线路板2旋转，编码器外圈232固定装设有中部带孔的旋钮4，即旋钮4的中部开孔，旋钮4与编码器外圈232固定连接，按键固定座7'及按键支架8'均设于旋钮4中部孔中。
上述方案能够实现旋钮4旋转，并通过转动旋钮4控制编码器23动作；且能够实现旋钮4中部孔内的按键支架8'固定不动，并可以通过操作按键支架8'顶部的控制面板9上的按键标识91对产品进行控制。
一个具体实施例中，如图34、图38至图41所示，控制盒组件包括：控制盒后盖5、线路板2、控制盒6、旋钮4、按键固定座7'、按键支架8'和控制面板9。其中，控制盒后盖5上开设有用于容置线路板2的容置槽51，线路板2安装在容置槽51中，线路板2上装设有编码器23，按键固定座7'固定在线路板2上或线路板2的编码器内圈231上，控制盒6盖装在控制盒后盖5上，控制盒6上与编码器23的对应位置开设有通孔，旋钮4穿过通孔并固定于编码器外圈232上，可选地，旋钮4通过设于其上的旋钮扣41扣合到编码器外圈232上，按键支架8'装设于按键固定座7'顶部，且按键支架8'固定于按键固定座7'或编码器内圈231或线路板2上，控制面板9贴在按键支架8'顶部。
在一个实施例中，如图35、图36、图47和图48所示，按键固定座7'固定于编码器内圈231或线路板2上，按键支架8'固定于编码器内圈231或线路板2上，按键支架8'和按键固定座7'中的一个上设有导向筋84'或导向柱，另一个上设有与导向筋84'或导向柱相配合的导向槽72'或导向孔。
在一个实施例中，如图35、图36、图45和图48所示，按键支架8'上设有导向筋84'或导向柱，按键固定座7'上设有导向槽72'或导向孔，导向槽72'或导向孔的顶部凸出编码器23的顶部端面。
一个具体实施例中，如图36所示，按键支架8'上设计有导向筋84'或导向柱，如图35所示，按键固定座7'上设计有导向槽72'或导向孔(亦可在按键支 架8'上设计导向槽或导向孔，在按键固定座7'上设计导向筋或导向柱)，装配时，将按键支架8'的导向筋84'或导向柱塞入按键固定座7'的导向槽72'或导向孔中，使得按键支架8'上的扣位能准确扣合在线路板2上或编码器23中部孔的内侧壁上，且按键固定座7'的最外围尺寸需小于编码器外圈232可活动的圈的外径尺寸；按键固定座7'装配完成后，按键固定座7'的导向槽72'或导向孔顶部高度需高于编码器23最顶端位置高度，在按键支架8'装配时，按键支架8'顶部面沉入到旋钮4顶部面以下前，按键支架8'的导向槽72'或导向柱就已经与按键固定座7'的导向槽72'或导向孔相配合，利于对按键支架8'进行顺利装配。
具体装配时，如图38至图41所示，在按键支架8'上设计有导向筋84'或导向柱，在按键固定座7'上设计有与按键支架8'的导向筋84'或导向柱相配合的导向槽72'或导向孔，装配时，把旋钮4固定在编码器外圈232上，将按键固定座7'通过扣位扣合在编码器23中部孔的内侧壁或扣合在控制板上，按键固定座7'也可不通过扣位固定而直接放在编码器23中部孔中，只通过编码器23内侧壁的筋位进行前后左右限位，或在按键固定座7'上设计筋或柱子插装在线路板2上进行前后左右限位，旋钮4和按键固定座7'两零件的装配顺序可对调；然后装配按键支架8'，装配时，因按键固定座7'的导向槽72'(或导向孔)高度较高，且导向槽72'顶部可增加大斜角或大圆角的结构导向，所以在装配作业时，在按键支架8'顶部塞入编码器23的中部孔内之前，按键支架8'的导向筋84'或导向柱就已经与按键固定座7'的导向槽72'或导向孔相配合，此时仅需往下按压按键支架8'即可准确无误地将按键支架8'插装到位，使得按键支架8'上的扣位能准确扣合在线路板2上或编码器23中部孔的内侧壁上。
实施例四：
如图49至图56所示，控制盒组件包括：按键支架8"，按键支架8"上设有按键柱子81"，按键柱子81"通过连接于按键支架8"的弹性筋82"与按键支架8"相连，如图56所示，弹性筋82"的顶部端面到按键柱子81"的顶部端面的距离H4与按键柱子81"的总长度L3之比在1/3～2/3范围内。如图56所示，图示中的L3表示按键柱子81"的总长度，H4表示弹性筋82"的顶部端面到按键柱子81"的顶部端面的距离，1/3L3≤H4≤2/3L3。
设计弹性筋82"的顶部端面到按键柱子81"的顶部端面的距离与按键柱子81"的总长度之比在1/3～2/3范围内，使弹性筋82"处于按键柱子81"的中段位置，这样当按键柱子81"发生歪斜时，会使得按键柱子81"顶部和底部的歪斜量相对平均，从而使得在按键柱子81"较长的情况下按压按键柱子81"的顶部时按键柱子81"的底部不会产生较大幅度摆动，也即减小了按压控制面板9上的按键标识91(如按键凸包)时可能造成的按键柱子81"的歪斜程度，使得按压按键标识91时按键标识91能够通过按键柱子81"精准地压在线路板按键22上，从而保证了按键的可靠性，很好地解决了现有方案中因按键柱子81"过长，按键柱子81"容易歪斜而导致按键失效的问题。
具体而言，因按键柱子81"与按键支架8"之间仅通过弹性筋82"相连，所以该弹性筋82"是按键柱子81"摆动的支点位置，当按键柱子81"摆动相同角度时，按键柱子81"端部距离弹性筋82"支点越远，按键柱子81"摆动后按键柱子81"端部偏离线路板按键22中心距离越远，反之则越近。现有按键结构当按键柱子81"较长时，按键柱子81"底部距离弹性筋82"支点很远，所以按动控制面板9上的按键标识91时，按键柱子81"顶部摆动较小，而远离支点位置的按键柱子81"底部摆动会很大，致使按键柱子81"底部端面极易偏离线路板按键22，导致按键柱子81"无法压住线路板按键22从而导致按键失效；在本申请的上述方案中，设计弹性筋82"的顶部端面到按键柱子81"的顶部端面的距离与按键柱子81"的总长度之比在1/3～2/3范围内，也即弹性筋82"处于按键柱子81"的中段位置，所以当按键柱子81"和现有结构方案倾斜相同角度时，尽管按键柱子81"顶部和底部都会歪斜，但本申请的上述方案中按键柱子81"顶部和底部的歪斜量相对平均，歪斜量约为现有结构方案柱子底部歪斜量的二分之一，且控制面板9的按键标识91和线路板2的线路板按键22都容许按键支架8"的按键柱子81"有小范围容错量，所以本申请的上述方案比现有方案更为稳定可靠，较好解决了现有方案存在的问题。
在一个实施例中，如图49、图50、图52至图54所示，按键支架8"顶部设有按键柱子81"的位置设有沉孔83"，按键柱子81"位于沉孔83"内，弹性筋82"设于沉孔83"底部，弹性筋82"与沉孔83"的孔内壁连接。
在按键支架8"顶部设有按键柱子81"的位置设计一沉孔83"，并将弹性筋 82"设于沉孔83"底部，这样设计便于通过合理设计沉孔83"的深度来确定弹性筋82"在按键支架8"上的设置位置，进而确定按键柱子81"与按键支架8"的连接位置，以使得装配完成后，弹性筋82"处于按键柱子81"的中段位置，避免按键柱子81"发生较大幅度摆动；并且沉孔83"的设置，能够确保按键标识91按到控制面板9底部面以下位置时按键标识91仍能按动，从而保证了按键的手感不受影响。
在一个实施例中，如图56所示，沉孔83"的深度与按键柱子81"的总长度之比在1/3～2/3范围内，图示中的L3表示按键柱子81"的总长度，H5表示沉孔83"的深度，1/3L3≤H5≤2/3L3。
由于按键标识91的高度通常较小，因此与之对应的按键柱子81"通常略微凸出按键支架8"的顶部端面或者与按键支架8"的顶部端面平齐，且弹性筋82"设于沉孔83"底部，因此在加工按键支架8"时，可以根据按键柱子81"的总长度设计沉孔83"的深度，这样装配完成后，就能够保证弹性筋82"的顶部到按键柱子81"的顶部端面的距离与按键柱子81"总长度之比在1/3～2/3范围内，使得在实际加工操作时更方便。
在一个实施例中，如图53和图54所示，弹性筋82"的顶部端面与沉孔83"的内侧底面平齐；或弹性筋82"的顶部端面构造成沉孔83"的内侧底面，以使得弹性筋82"及沉孔83"的加工更方便。
在一个实施例中，如图55所示，弹性筋82"包括环形筋及连接在环形筋外壁和沉孔83"的孔内壁之间的连接筋，按键柱子81"设于环形筋的内侧中且与环形筋固定连接。
按键柱子81"通过连接于按键支架8"上的弹性筋82"与按键支架8"相连，使得在按键柱子81"被按压时，按键柱子81"能够发生轴向移动并向线路板按键22传递按压力，从而实现线路板2上的线路板按键22动作。
在一些实施例中，如图53和图54所示，按键柱子81"的顶部端面凸出按键支架8"的顶部端面或与按键支架8"的顶部端面平齐。
设计按键柱子81"的顶部端面凸出按键支架8"的顶部端面或与按键支架8"的顶部端面平齐，可以减小按键柱子81"的顶部端面与按键标识91的内侧端面之间的距离，从而确保对按键标识91施加较小的按压力，使按键标识91 移动较小距离，即可带动按键柱子81"沿轴向移动并将按压力传递给线路板按键22，从而确保按压按键的灵敏性。
在一个实施例中，如图54所示，按键柱子81"的顶部端面到按键支架8"顶部端面的距离H6在0mm～1.5mm范围内，图示中的H6表示按键柱子81"的顶部端面到按键支架8"顶部端面的距离。
由于按键标识91的高度通常较小，因此设计与之对应的按键柱子81"的顶部端面到按键支架8"顶部端面的距离在0mm～1.5mm范围内，以避免按键柱子81"的顶部端面凸出按键支架8"顶部端面的距离过大而影响按压手感。
在一些实施例中，如图49所示，控制盒组件包括：线路板2、按键支架8"和控制面板9，具体地，线路板2上设有线路板按键22；按键支架8"固定于线路板2上，按键支架8"上设有按键柱子81"，按键柱子81"通过连接于按键支架8"的弹性筋82"与按键支架8"相连，如图56所示，弹性筋82"的顶部端面到按键柱子81"的顶部端面的距离H4与按键柱子81"的总长度L3之比在1/3～2/3范围内；控制面板9装设于按键支架8"顶部，控制面板9上设有与线路板按键22对应的按键标识91，按键柱子81"位于按键标识91和线路板按键22之间，按键标识91被按压时能够带动按键柱子81"按压线路板按键22。
通过按压控制面板9上的按键标识91，带动按键支架8"上的按键柱子81"移动，按键柱子81"将按压力传递给线路板2上的线路板按键22，从而实现对产品的控制；具体地，按键标识91为具有标识的功能键，如煮汤、煮粥等标识，为了提高按压手感，按键标识91处通常设置为提高按压手感的凸包，当然，按键标识也可不凸起来，具体可以根据实际产品情况进行合理设计。
在一个实施例中，如图49、图53和图54所示，线路板2上装设有能够相对线路板2旋转的旋转件(如编码器23)，线路板按键22设于旋转件内侧，按键支架8"扣合在位于旋转件内侧的线路板2上，控制盒组件还包括旋钮4，旋钮4套设在按键支架8"外侧且扣合在旋转件上。
上述方案能够实现旋钮4旋转，且能够实现按键支架8"固定不动，并可以通过操作按键支架8"顶部的控制面板9上的按键标识91对产品进行控制；并且上述旋钮4的设置，会增大线路板按键22与按键标识91的距离，因此通过在按键支架8"顶部设计具有一定深度的沉孔83"，可以增大固定于沉孔83" 底部的弹性筋82"的顶部端面到按键柱子81"的顶部端面的距离，从而使得弹性筋82"处于按键柱子81"的中段位置，避免按键柱子81"的底部发生较大幅度摆动，提升按键被按压时的可靠性。
具体地，如图51和图54所示，按键支架8"上设有按键支架扣84"，线路板2上设有第一扣位24，按键支架扣84"扣合在第一扣位24上，实现按键支架8"固定在线路板2上；旋钮4上设有旋钮扣41，线路板2的旋转件上设有第二扣位25，旋钮扣41扣合在第二扣位25上，实现旋钮4固定在线路板2的旋转件上。
在一个实施例中，如图49所示，控制盒组件包括：控制盒后盖5，控制盒后盖5上设有容置槽51，线路板2安装于容置槽51中，控制盒6盖装在控制盒后盖5上且与控制盒后盖5固定连接，以利用控制盒6及控制盒后盖5将整个按键装置装配为一体。
本申请第三方面的实施例提供了一种家用电器，包括如上述任一实施例的控制盒组件，并具有上述任一实施例的控制盒组件的有益效果，在此不再赘述。
在本申请的一个实施例中，所述的家用电器为电压力锅，当然的家用电器也可以是具有控制盒组件的其他家用电器如电饭煲、豆浆机、洗衣机等，也即上述的控制盒组件广泛适用于各种小家电产品中，只要不脱离本申请的设计构思，均应在本申请的保护范围内。
综上所述，本申请实施例提供的控制盒组件，通过在导光圈凸包顶部设置两个斜面，且两个斜面的每个斜面都有两个方向的角度，从而无需在导光圈的内孔侧壁上进行喷涂处理或贴反光纸，就能够实现将从导光圈凸包顶部斜面反射出来的光线重新反射回导光圈内部，并在导光圈内进行多道反射，光线反射到导光圈底部齿条上，然后被齿条斜面反射到导光圈顶部，使得导光圈顶部被点亮，降低了材料及人工成本，并提高了批量生产时产品的生产效率。
