技术领域technical field
本实用新型涉及烟草加热领域，特别是涉及一种烟草加热器。The utility model relates to the field of tobacco heating, in particular to a tobacco heater.
背景技术Background technique
烟草制品作为一种特殊的消费品，在世界消费品市场上占有相当大的比重。目前世界上生产的卷烟类型主要是烤烟型、混合型、香料烟型和晾晒烟型；卷烟的主要形式是滤嘴卷烟。Tobacco products, as a special kind of consumer goods, occupy a considerable proportion in the world consumer goods market. At present, the types of cigarettes produced in the world are mainly flue-cured tobacco, mixed type, oriental tobacco and air-cured tobacco; the main form of cigarettes is filter cigarettes.
近年来，传统卷烟对健康及环境的影响问题开始逐步受到世界各国的重视。烟草生产商均致力于向消费者提供危害更低的烟草制品，为此，研制出了一种能够通过加热而不点燃烟草的方式进行抽吸的烟草制品。由于加热温度远低于燃烧温度，因此能有效降低烟草高温燃烧裂解产生的有害成分，使主流烟气的化学组分释放量大大降低。同时，与常规卷烟引燃的方式不同，加热不燃烧型烟草在抽吸间歇时烟草处于不加热状态，因此，侧流烟气和环境烟气也大幅度降低。作为烟草消费的新形式，加热不燃烧型烟草制品逐步受到部分烟草消费者的欢迎，正日益被大多数国家的卷烟消费者接受。In recent years, the impact of traditional cigarettes on health and the environment has gradually attracted the attention of countries all over the world. Tobacco manufacturers are committed to providing consumers with less harmful tobacco products. To this end, a tobacco product that can be smoked by heating without lighting the tobacco has been developed. Because the heating temperature is much lower than the combustion temperature, it can effectively reduce the harmful components produced by high-temperature combustion and cracking of tobacco, and greatly reduce the release of chemical components in mainstream smoke. At the same time, different from the ignition method of conventional cigarettes, heat-not-burn tobacco is in a non-heated state during puffing intervals, so sidestream smoke and ambient smoke are also greatly reduced. As a new form of tobacco consumption, heat-not-burn tobacco products are gradually welcomed by some tobacco consumers, and are increasingly accepted by cigarette consumers in most countries.
然而，现有加热不燃烧型烟草的加热器一般都采用外部热源整体加热烟草的方式，例如，在申请号为200520130514.5的中国专利文献中，公开了一种烟草加热器。该烟草加热器假设在水烟器上，该水烟器包含一个具有承盘点壶身以及一个架设在壶身上且面积小于承盘并供烟草摆放的烟草碟，该烟草加热器包含：一个罩筒、一个位于罩筒的筒壁上的握把、以及一个安装在罩筒上的加热单元，该加热单元包括安装在罩筒的加热空间内的电热管；使用时，放有烟草的烟草碟伸入加热空间内并临近电热管，当电热管通电时可以对碟内烟草加热，所产生的烟雾由水烟器上的吸烟管吸出。再例如，在申请号为200920006702.5的中国专利文献中公开了一种烟草加热器。该烟草加热器包含一个罩筒机构与一个加热件；该罩筒机构包括一个用以罩设于烟草碟外且间隔位于水烟壶的承盘上方的罩盖、及至少一个安装结合于罩盖上并可相对于罩盖往下突伸而改变罩盖高度地往下靠抵于承盘上的高度调整件；该加热件安装于罩盖中，用于产生加热烟草的高温。However, the existing heat-not-burn tobacco heaters generally use an external heat source to heat the tobacco as a whole. For example, a tobacco heater is disclosed in Chinese Patent Document No. 200520130514.5. The tobacco heater is assumed to be on a hookah, and the hookah includes a kettle body with a support plate and a tobacco dish erected on the kettle body and having an area smaller than the tray for placing tobacco. The tobacco heater includes: a cover tube, A handle located on the cylinder wall of the hood cylinder, and a heating unit installed on the hood cylinder, the heating unit includes an electric heating tube installed in the heating space of the hood cylinder; when in use, the tobacco disc with tobacco extends into the In the heating space and adjacent to the electric heating pipe, when the electric heating pipe is energized, the tobacco in the dish can be heated, and the smoke generated is sucked out by the smoking pipe on the hookah. For another example, a tobacco heater is disclosed in the Chinese patent document with application number 200920006702.5. The tobacco heater includes a cover mechanism and a heating element; the cover mechanism includes a cover for covering the tobacco dish and spaced above the bearing plate of the hookah, and at least one cover mounted on the cover And it can protrude downward relative to the cover to change the height of the cover and lean against the height adjustment member on the support plate; the heating member is installed in the cover and is used to generate high temperature for heating tobacco.
由于采用外部热源整体加热，加热空间大，需要较长时间将热传导至烟草本身，故该方式既浪费能源又易造成加热过程的前后阶段烟气的不均匀和劣化。并且，由于很难将热量传导至烟草的内部，只能有效加热烟草表面，故烟草的利用率较低。另外，使用完成后，由于腔室内高温无法快速散去，在取出烟草的过程中，存在将消费者烫伤的危险。Since the external heat source is used for overall heating, the heating space is large, and it takes a long time to conduct the heat to the tobacco itself, so this method not only wastes energy, but also easily causes unevenness and deterioration of the flue gas in the front and rear stages of the heating process. Moreover, since it is difficult to conduct heat to the inside of the tobacco, only the surface of the tobacco can be effectively heated, so the utilization rate of the tobacco is low. In addition, after use, since the high temperature in the chamber cannot be dissipated quickly, there is a danger of scalding the consumer during the process of taking out the tobacco.
