Description

tobacco heater

technical field

The invention relates to the field of heaters, in particular to a tobacco heater. the

Background technique

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. the

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, unlike conventional cigarettes that smolder, 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. the

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 with 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 can protrude downward relative to the cover to change the height of the cover and lean against the height adjusting member on the support plate; the heating member is installed in the cover and is used to generate high temperature for heating tobacco. the

Since the external heat source is used for overall heating, 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 smoke 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. the
