【具体实施方式】
下面结合附图和较佳的实施例对本发明作进一步说明。
如图 1-6所示， 本发明提供一种饭盒的具体实施例， 该饭盒包括： 饭盒主体 400以及饭盒盖 100, 在所述饭盒盖 100上设置有蒸汽溢出孔 1011 , 在所述饭盒 盖 100上， 还设置有用于遮盖所述蒸汽溢出孔 1011的溢出孔盖 102; 所述溢出 孔盖 102包括一固定在所述饭盒盖 100上的的安装柱 1022以及设置在所述安装 柱 1022—端并将所述溢出孔 1011封闭在其内部的弹性伞形盖帽 1021。 如图 7 所示， 当按压所述伞形盖帽 1021顶端时， 所述伞形盖帽 1021反向变形， 这样， 就可以使所述溢出孔盖 102处于打开状态， 溢出孔 1011不受伞形盖帽 1021的 覆盖而处于打开状态。
如图 3-图 4所示， 所述饭盒盖 100上设置有一安装孔 101 , 所述安装柱 1022 的另一端设置有倒扣 1024, 所述倒扣 1024与所述伞形盖帽 1021将所述安装柱 限定在所述安装孔 101 内。 利用盖帽 1021和倒扣 1024将安装柱限定在安装孔 101内， 从而方便盖帽的按压， 使盖帽反向变形。
如图 6所示， 所述安装孔 101的上端口设置有一沿安装孔 101孔口边缘设置 的一圏凸台 1013, 结合图 3所示， 所述伞形盖帽 1021封闭所述溢出孔时其内侧 贴紧在所述凸台 1013处。 这样可以利用凸台 1013, 使得伞形盖帽 1021的封闭 效果更好。 所述凸台 1013的截面呈三角形结构， 在所述安装孔 101的上端口形成倒锥 形扩口。该三角形凸台 1013形成的倒锥形扩口，有助于保持变形后的盖帽形状， 同时， 扩口外侧， 凸台与伞形盖帽的接触面更大， 更有利于保持封闭状态。 当 然， 该倒锥形扩口也不一定是要通过设置凸台实现， 也可以对安装孔 101 侧壁 外扩设置。 当按压伞形盖帽时， 伞形盖帽反向变形， 安装柱下降， 倒锥形扩口 可以容纳一部分变形的盖帽， 从而有助于保持盖帽的变形状态。
如图 6所示， 所述蒸汽溢出孔 1011设置在所述安装孔 101的周围， 并且述 蒸汽溢出孔 1011设置在所述凸台 1013上， 沿所述凸台 1013均布在所述安装孔 的周围。
在本实施例， 所述安装柱 1022也为弹性材料制成， 其外径大于所述安装孔 101的孔径。 这样有利于安装柱 1022在安装孔 101内固定位置， 当按压时， 安 装柱往下移动， 由于其弹性结构， 使其具有弹性， 进而保持位置在按压后的状 态。
并且， 如图 4-5所示， 所述安装柱 1022为中空结构， 具有孔 1023 , 这样使 其弹性变形更容易。
在本实施例中，所述伞形盖帽 1021的边缘设置有凸沿 1025。通过凸沿 1025 , 增加伞形盖帽与饭盒盖的接触面积， 保持更好的封闭效果。
如图 8所示， 饭盒内部还设置有： 设置在饭盒主体 400内部的内胆 200以及 加热装置 300,其中所述加热装置 300包括一贴附在所述内胆 200的外表面的一 层用于发热的加热片 301。
加热片 301设置在所述内胆 200的底面， 其大小、 形状与所述内胆 200的底 面相对应， 从内胆 200的底面加热， 这样加热片 301的设置比较方便， 同时加 热效果也更好。 当然， 也可以在内胆 200的全部外周表面贴附上加热片， 但是， 这样不易加工， 而且， 底部设置加热片已能达到加热的需求。
在加热片 301上设置有锁附孔 302, 对应的在所述内胆 200的外表面即底面 设置有与所述锁附孔 302对应的螺孔柱 202,所述加热片 301通过螺丝锁附到所 述内胆的外表面上。 由于内胆厚度不大， 因此通过螺孔柱、 螺丝 304及锁附孔 302锁附加热片 301到内胆 200底面上， 此种锁附结构较为筒单， 也不需要加大 内胆的厚度。 另外， 自加热饭盒的饭盒主体 400底部也设置有与所述螺孔柱 202 对应的锁附孔 402, 所述内胆 200、 加热片 301以及所述饭盒主体 400通过螺丝 304同时锁附在一起， 这样即可将多个部件通过一组螺丝同时实现锁附， 结构相 对筒单， 加工和组装较为方便。
在本实施例中， 所述加热装置 300还包括一用于控制所述加热片 301进行加 热的控制电路（图中未示出）， 控制电路用于实现智能控制加热， 使得加热饭菜 时能够保证加热问题及加热时间。 控制电路设置在所述内胆 200 的一侧底部， 所述内胆 200设置有一用于避让所述控制电路的凹陷口 201 ,这样使得饭盒内部 空间足够， 保证饭盒的整体结构不会增大。
同时， 本实施例中的饭盒还设置有用于提示饭盒使用状态的指示灯 405。 而 所述内胆 200底部一侧对应于所述指示灯 405的位置处设置有一用于固定所述 指示 405灯及其电路板的固定架 205 , 所述饭盒主体 400对应于所述固定架 205 的位置设置有用于露出所述指示灯 405的开孔。
在本实施例中， 所述加热片 301为传热效率高的金属加热片， 该加热片可采 用钣金加工实现。 所述内胆 200可以是塑胶或不锈钢材质。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明， 不能 认定本发明的具体实施只局限于这些说明。 对于本发明所属技术领域的普通技 术人员来说， 在不脱离本发明构思的前提下， 还可以做出若干筒单推演或替换， 都应当视为属于本发明的保护范围。
