Description

电子蜡烛结构及生产方法、电子蜡烛的蜡筒 技术领域
本发明涉及仿真电子蜡烛技术领域，更具体地说，本发明涉及一种电子蜡烛的结构方式及生产方法。
背景技术
蜡烛作为一种重要的装饰品，广泛应用于生日宴会、烛光晚餐等重要场合调节气氛。然而传统的蜡烛点燃后不但产生烟气，污染环境，而且明火存在安全隐患。电子蜡烛由于其安全环保的特点不断取代传统蜡烛成为了一种被广泛消费的商品。
由于市场对于电子蜡烛高仿真度的需求，电子蜡烛的外表面通常都是用蜡制成，保持外表面的观感和触感与传统蜡烛一样。现有的电子蜡烛的基本包含了蜡筒1(蜡制外壳)和机芯2，机芯2包括机芯主体3、火焰头4和设置在火焰头内部的光源9，机芯主体3底部的蜡筒固定面5固定于蜡筒1内空8，机芯的顶部中心固定面6与蜡筒火焰头通孔7配合，火焰头4位于蜡筒1的上方，参见图1‐4。现有技术中生产蜡筒的方法是：制作一个用于成型蜡筒的凹模，此凹模的内空部分的表面就是蜡筒的外表面，将熔融的蜡水浇灌进凹模的内空部分，也就是蜡水在凹模里形成了一个实心蜡筒的形状，蜡水接触凹模的内空表面部分最先开始冷却硬化，并逐步往中心推进，当蜡筒的外表面形成一定的硬化厚度之后，将中心尚未融化的蜡水倒掉，然后将初步成型的蜡筒从凹模中取出，此时的蜡筒1初步具有图4的样子，区别在于蜡筒内空部分由于是直接倒掉未凝固的蜡水所形成，所以其内空部分的形状不规则，不统一，会影响到机芯的装配，所以需要对初步成型的蜡筒进行再次加工，用机加工的方式去掉多余的蜡，做成内空规则的可以用于装配机芯的蜡筒。机芯通常通过其上的蜡筒固定面用蜡水或其它粘接材料固定于蜡筒内空。目前蜡筒的结构和生产方法导致其生产效率低、成本高。首先，成型一个有内空的蜡筒需要相当于实心蜡筒体积的蜡水，也就是需要消耗更多的能源加热形成更多的蜡水用于浇灌蜡筒，同时浇灌的蜡水越多冷却成型的周期也就更长，通常成型一个蜡筒需要 的冷却时间大约要0.5‐3个小时。其次，蜡筒的材质熔点低、机械强度低，没有更高机械强度材质所做成的内衬作支撑，所以蜡筒的壁必须要保持一定的平均厚度才能满足所述蜡筒成型加工过程和正常使用过程所需要的机械强度，通常平均厚度要在5毫米以上，这种蜡筒的结构也导致了用蜡量的增加。
发明内容
本发明要解决的技术问题在于，针对现有技术的上述不足之处提出一种生产效率高、成本低和机械强度高的电子蜡烛结构及生产方法、电子蜡烛的蜡筒。

具体实施方式
现结合附图，对本发明的实施例作详细说明。
如图5至9所示，一种电子蜡烛，包括蜡筒10，内衬20和机芯30。所述内衬20包含上壁21和侧壁22，以及由上壁和侧壁围成的内部空间23。所述机芯30的机芯主体31固定在所述内部空间23。所述内衬20在本实施例中采用半透明的塑胶材料PP,平均壁厚为1.5毫米。所述蜡筒10均匀包裹在所述内衬20的外表面，所述蜡筒10平均壁厚0.6-3毫米，本实施例中，壁厚为 1.5毫米。所述内衬20包含固定扣24。所述机芯30包括光源32、火焰头33和机芯主体31，所述机芯主体31包含避空位311、固定位312、光源控制电路、电池(电源)、开关，后三者为常规设置，未在图中显示。当组装所述机芯30到所述内衬20上时，首先将所述内衬20上的所述固定扣24放置到所述避空位311，然后相对旋转所述内衬20和所述机芯30，使所述内衬20上的所述固定扣24旋转到所述固定位312得以固定。在本实施例中，所述内衬20还包含一个顶部固定通孔25，所述机芯还包含一个顶部中心固定柱面34，所述顶部中心固定柱面34与所述顶部固定通孔25接触。所述蜡筒10是由融化的蜡水直接冷却凝固在所述内衬20的外表面上而成型，所述蜡筒的外表面借助一个凹模的内表面而成型，所述机芯的机芯主体固定在所述内衬的内部空间。
图10-16表示了一种电子蜡烛的生产方法。所述生产方法包含了至少两个生产模具的使用：凹模40和凸模50。所述凹模40用于成型所述蜡筒10的外表面。在本实施例中，所述凸模50上设置有避空槽51和固定槽52，通过如下方法将所述内衬20固定在所述凸模50上：将所述内衬20上的固定扣24对准所述凸模上的避空槽51，由下而上移动所述内衬20至所述固定扣24与所述固定槽52平齐，旋转所述内衬20至所述固定扣24卡在所述固定槽52的位置。所述内衬和所述凸模的可拆卸固定方式也可以是螺纹配合的方式或其它任何可拆卸固定的方式。
在本实施例中，凹模40采用导热良好的金属比如铝材制作。优选地，可以减少蜡水冷却固化的时间，提高生产效率。图12表示了成型前开模状态。所述内衬20固定在所述凸模50上，所述凸模50在所述凹模40的上方，一定量的融化的蜡水60被灌入凹模40。在本实施例中，蜡水60在灌入凹模前的温度为110摄氏度左右。在本实施例中，蜡水的配方为：94％的标号为58的全精炼石蜡+6％的AC6(硬化蜡)。
图13表示了成型中合模状态。在本实施例中，所述凹模40保持不动，所述凸模50垂直下行至合模状态。在其它实施例中，也可以是所述凸模保持不动，所述凹模垂直上行至合模状态，也可以是两者在竖直方向上同时相向而行至合模状态。在本实施例中，在所述凸模50下行至合模状态的过程中，所述蜡水60受到挤压而流动，最终在合模状态时流动成所述蜡筒的形状。从内衬底面26到凹模顶面42的距离为废料槽41的高度，所述废料槽的高度需要设 置为5毫米以上。在本实施例中，此高度为20毫米。废料槽41为开口状态，空气可以从所述凹模40和凸模50的外面进入到废料槽41。由于所述蜡筒在冷却成型过程中会向下收缩，通常会在所述内衬底面处形成高低不平的形状，所述废料槽的设计可以解决这个问题，每次成型所述蜡筒的时候，确保灌入凹模的蜡水的用量是可以使蜡水在合模状态下可以高过所述内衬底面并进入所述废料槽形成多余废蜡。进一步地，所述废料槽的顶部不能被所述凸模所封闭而形成密闭空间，从而隔绝了外界空气进入废料槽，这样会影响蜡水在冷却过程中的均匀收缩，引起所述蜡筒表面质量降低。
在本实施中，蜡水冷却固化至可以开模的时间为10分钟左右，相比较现有生产方式的冷却固化时间0.5-3小时，成型效率提高了很多倍。
图14表示了成型后开模状态。在本实施例中，所述凹模40保持不动，所述凸模50垂直上行至开模状态。所述蜡筒10连同所述内衬20被所述凸模50带离所述凹模40。
图15表示了将所述蜡筒10和内衬20从所述凸模50取下的状态。在本实施例中，旋转所述蜡筒和内衬，使所述内衬上的固定扣24从所述凸模50上的固定槽52的位置旋转到避空槽51的位置，然后将所述蜡筒10和内衬20往下脱出所述凸模。
图16表示了将所述蜡筒10上的多余废蜡70从所述内衬底面去掉之后所得到的最终需要的所述蜡筒和内衬组件。
图17-22表示了另一种电子蜡烛的生产方法。所述生产方法包括凹模40和未裁切内衬20的使用。所述凹模40用于成型所述蜡筒10的外表面。在本实施例中，所述凹模40上设置有避空位45和固定位46。通过如下方法将所述未裁切内衬20固定在所述凹模40上：将所述未裁切内衬外表面上的固定扣24对准所述凹模40上的避空位45由上而下将所述未裁切内衬20装配到所述凹模40内，然后旋转所述未裁切内衬至所述固定扣24卡在所述固定位46的位置。相反的操作可以将所述未裁切内衬20从所述凹模40取下。
图20表示成型前开模状态。一定量融化的蜡水60被灌入凹模40。在本实施例中，蜡水在灌入凹模前的温度为110摄氏度左右，蜡水的配方为：94％的标号为58的全精炼石蜡+6％的AC6(硬化蜡)。
图21表示成型中合模状态。将所述未裁切内衬20装配到所述凹模40上， 同时所述未裁切内衬挤压蜡水流动呈蜡筒形状。其它同实施例1。
图22表示将所述将未裁切内衬20从凹模40上取下的状态。取下以后，将所述未裁切内衬沿内衬底面26以上的部分裁切掉，就得到了如同实施例1中图16所示的蜡筒。
本发明电子蜡烛的蜡筒，是由融化的蜡水直接冷却凝固在一个内衬的外表面上而成型，所述蜡筒的外表面借助一个凹模的内表面而成型。优选地，该蜡筒的平均厚度做成0.6-3毫米，平均厚度3毫米以内的蜡筒由于壁厚相对小，用蜡量少，成型周期短，有利于提高生产效率，但是平均厚度低于0.6毫米，则不容易获得均匀整齐的表面效果。
优选地，所述内衬是由半透明或透明的材料做成。由于在成型所述蜡筒的过程中，所述蜡筒与所述内衬外表面的结合不一定能做到完全密实，特别是所述蜡筒壁很薄的情况下，当观察所述蜡筒的外表面时，结合不密实的区域就容易显示出与结合密实的区域不一样的颜色，当所述内衬是由半透明或透明的无色或浅色材料做成的情况下，所述蜡筒外表面的颜色不一致的现象会大大减轻，从而提升产品的外观质量。
优选地，所述内衬的外表面是粗糙的而不是光滑的，粗糙的外表面可以帮助所述内衬的外表面与所述蜡筒更好地结合。
应当理解的是，以上实施例仅用以说明本发明的技术方案，而非对其限制，对本领域技术人员来说，可以对上述实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改和替换，都应属于本发明所附权利要求的保护范围。
