技术领域technical field
本申请涉及不燃烧电子烟技术领域，具体而言，涉及一种红外加热体及其制备方法、以及加热不燃烧烟具。The present application relates to the technical field of non-burning electronic cigarettes, in particular, to an infrared heating body, a preparation method thereof, and a heat-not-burning smoking appliance.
背景技术Background technique
加热不燃烧(HNB)烟具是通过加热元件对烟卷中的烟草进行烘烤而产生烟雾。不燃烧电子烟采用低温烘烤的方式对烟草进行加热，相较于传统直接点燃烟草吸食的方式，该方式能够有效降低有害成分的产生，从而减少烟草高温燃烧裂解产生的焦油以及一氧化碳等对人体有害的物质。不燃烧电子烟可将烟草中的尼古丁变成蒸汽析出，烟草本身不燃烧，无烟灰，烘烤产生的焦油含量较低，能够有效减少二手烟对人体的危害。Heat-not-burn (HNB) smoking appliances use a heating element to heat the tobacco in the cigarette to generate smoke. Non-burning e-cigarettes use low-temperature baking to heat tobacco. Compared with the traditional method of directly lighting tobacco for smoking, this method can effectively reduce the production of harmful components, thereby reducing the impact of tar and carbon monoxide produced by high-temperature combustion and cracking of tobacco on the human body. hazardous substances. Non-burning e-cigarettes can convert the nicotine in tobacco into vapor to precipitate, the tobacco itself does not burn, has no soot, and the tar content produced by baking is low, which can effectively reduce the harm of second-hand smoke to the human body.
现有市场上的不燃烧电子烟多以陶瓷片发热体为主，烟草在这种发热体下加热时容易受热不均，使得加热的烟草气味口感难以保持一致。Most of the non-burning electronic cigarettes on the existing market are based on ceramic sheet heating elements. When tobacco is heated under such heating elements, it is easy to be unevenly heated, which makes it difficult to maintain a consistent smell and taste of heated tobacco.
此外，为了保障加热元件对烟卷中烟草的加热效果，通常需要烟卷与壳体内壁紧密贴合，这要求烟卷直径与壳体的内径尺寸相匹配。由于烟卷的外径与壳体的内径相同或极为相近，在向烟具壳体内装放烟卷时，烟卷不易顺利地进入烟具壳体内中，因而易造成烟卷的损坏或者烟具壳体入口端的磨损。In addition, in order to ensure the heating effect of the heating element on the tobacco in the cigarette, it is usually necessary for the cigarette to closely adhere to the inner wall of the housing, which requires that the diameter of the cigarette matches the inner diameter of the housing. Since the outer diameter of the cigarette is the same as or very close to the inner diameter of the casing, when the cigarette is loaded into the casing of the smoking accessory, the cigarette is not easy to enter the casing of the smoking accessory smoothly, thus easily causing damage to the cigarette or abrasion of the inlet end of the casing of the smoking accessory.
