本发明涉及电子烟技术领域，特别是涉及一种发热片及电子烟。The invention relates to the technical field of electronic cigarettes, in particular to a heating sheet and an electronic cigarette.
电子烟主要用于戒和替代香烟，它可以模拟香烟的味道，但抽电子烟时却不会释放对人体有害的焦油、尼古丁和二手烟雾，它能提高尼古丁替代疗法的戒烟成功率，因此，电子烟在推出不久便受到市场的追捧和国家的重视。电子雾化香烟，其原理为发烟剂在雾化系统的电加热元件上受热气化成高温蒸汽并向开口端喷出，喷出后的蒸汽在大气中膨胀冷凝成烟状的微小液滴，从而形成类似传统卷烟的烟雾。Electronic cigarettes are mainly used to quit and replace cigarettes. It can simulate the taste of cigarettes, but it will not release harmful tar, nicotine and second-hand smoke when smoking electronic cigarettes. It can improve the success rate of smoking cessation in nicotine replacement therapy. Therefore, Electronic cigarettes have been sought after by the market and valued by the country shortly after their launch. The principle of electronic atomized cigarettes is that the smoking agent is heated and vaporized into high-temperature steam on the electric heating element of the atomization system and sprayed out to the opening. Thus forming smoke similar to traditional cigarettes.
