摘要：【中文】本发明提供一种自发热坐垫及其制作方法，包括垫体和发热组件，所述垫体囊封于所述发热组件，所述发热组件包括第一发热层、储能层和第二发热层，储能层设于所述第一发热层的上方；第二发热层设于所述储能层的上方，其中，所述第一发热层释放的热量大于所述第二发热层释放的热量。通过在第一发热层和第二发热层之间设置一储能层，储能层将集中释放的热量暂时的储存起来，防止热量集中传递至坐垫表面，当坐垫表面温度降低时，储能层通过热传递的方式将热量缓慢释放出来，如此既能够避免热量的集中释放造成的安全隐患，又能够维持较长一段时间的发热效果。 【EN】The invention provides a self-heating cushion and a manufacturing method thereof, wherein the self-heating cushion comprises a cushion body and a heating assembly, the cushion body is encapsulated in the heating assembly, the heating assembly comprises a first heating layer, an energy storage layer and a second heating layer, and the energy storage layer is arranged above the first heating layer; the second heating layer is arranged above the energy storage layer, wherein the heat released by the first heating layer is larger than the heat released by the second heating layer. Through set up an energy storage layer between first heat generation layer and the second heat generation layer, the temporary storage of heat that the energy storage layer will concentrate the release gets up, prevents that the heat from concentrating the transmission to the cushion surface, and when cushion surface temperature reduced, the mode that the energy storage layer passed through the heat transfer slowly releases the heat, so can enough avoid thermal concentrated release to cause the potential safety hazard, can maintain the effect of generating heat of longer a period again.
