The utility model is suitable for the field of daily necessities, and provides a portable heating and heat preservation lunch box. The lunch box comprises a shell, an upper cover with a rotating cover on the top of the shell, an inner bladder in the outer shell, the side wall of the inner liner and the side wall of the outer shell with a circular passage with a heating liquid circulation, and a seal at the bottom of the shell. The power bin is placed in the rechargeable battery, the top of the power supply bin is provided with a support for the internal bladder, the top of the bracket is fitted to the bottom of the inner bladder, the bottom of the bracket is hollow, the heating resistor is provided at the hollow part, and the heater is connected with the rechargeable power supply by the switch on the outer surface of the outer shell. . The heated liquid inside the enclosed annular channel is heated to heat the inside of the inner bile, which is beneficial to the uniform heating of the food inside the inner gallbladder, and can reduce the energy loss. But when the heating is finished, the heated liquid in the annular channel can be poured out to lighten the weight of the lunch box and be easy to carry.
【技术实现步骤摘要】
一种便携式加热保温饭盒
本技术属于生活用品领域,提供了一种便携式加热保温饭盒。
技术介绍
传统饭盒大多采用加热器加热金属盘,再由发热的金属盘传导到用具本体,由于金属盘和用具本体接触不够紧密,致使向外扩散的热量较多,因而用具本体的加热效率较低,且存在加热不均匀的现象。
技术实现思路
本技术实施例提供一种便携式加热保温饭盒,旨在解决通过金属盘加热用具本体,存在热效率较低及加热不均匀的问题。本技术提供了一种便携式加热保温饭盒,所述饭盒包括外壳,及与所述外壳顶部旋转盖合的上盖,及设于所述外壳内部的内胆所述内胆的侧壁与所述外壳的侧壁留有容加热液体流通的环形通道,所述外壳的底部设有密封的电源仓,所述电源仓内放置于可充电电池,所述电源仓的顶部设有用于固定内胆的支架,所述支架的顶部与所述内胆的底部贴合,所述支架的底部呈镂空状,在所述镂空的部位设有加热电阻,所述加热器通过设于外壳外表面的开关一与所述可充电电源连接。进一步的,所述外壳的外表面设有用于连接充电设备的输入接口,所述输入接口与所述可充电间电源连接。进一步的,所述外壳的外表面设有开关二、及用于连接移动终端的输出接口,所述开关二连接所 ...
