Heating module of multi-layer composite structure and electronic cigarette device

The invention provides a heating module of a multi-layer composite structure and an electronic cigarette device. The heating module comprises a heating body and an outer sleeve located outside the heating body. The heating body is linear or blocky or reticular. The outer sleeve is formed by sintering a dense inorganic material located on the inner layer and a porous ceramic material located on theouter layer. The outer sleeve is provided with a channel allowing the heating body and external power supply equipment to be connected. According to the heating module of the multi-layer composite structure and the electronic cigarette device, the problems of the burnt food smell and carbon deposition caused by the fact that a metal alloy heating wire with chemical activity and tobacco bar sufferfrom a chemical reaction are avoided. 本发明提供了一种多层复合结构的加热模组及电子烟器件，加热模组包括加热体和位于加热体外部的外部套筒，其中加热体为线状、块状或网状，所述外部套筒由位于内层的致密的无机材料以及位于外层的多孔陶瓷材料烧结而成，所述外部套筒设置有加热体与外部供电设备连接的通道。本发明所述的多层复合结构的加热模组及电子烟器件，以避免化学活性的金属合金发热丝与烟油发生化学反应导致的焦糊味和"积碳"问题
