Description

A non-combustion smoking device based on graphite heating

technical field

The invention relates to the technical field of novel cigarettes, in particular to a non-combustion smoking device based on graphite heating.

Background technique

As the mainstream product form of tobacco consumption, traditional cigarettes have a history of more than 100 years. With the change of people's lifestyle and consumption concept, the rapid progress of science and technology and the continuous acceleration of commodity upgrading, the needs and concerns of tobacco consumers are constantly changing. At the same time, affected by factors such as tobacco control and public opinion, traditional cigarettes The development of cigarettes is restricted, and the emergence of new cigarettes has become inevitable.

Studies have shown that cigarette smoke produced by burning cigarettes is extremely harmful to non-smoking people, and fires caused by smoking are difficult to eliminate. Nicotine and most tobacco aroma components can be transferred to the smoke at 200-500 degrees Celsius. The combustion temperature of conventional cigarettes is above 800 degrees Celsius. If the heating temperature of cigarettes is lowered to below 500 degrees Celsius, various harmful components of smoke can be greatly reduced. , while the aroma components are relatively less affected. Therefore, it is very meaningful to study a heat-not-burn cigarette smoking device that avoids shredded tobacco burning and satisfies the needs of consumers.

At present, the low-temperature cigarettes appearing on the market deliver nicotine and aroma to the human body by means of heat-not-burn tobacco, which are filled with tobacco substances. Low-temperature cigarette products have changed the way traditional cigarettes burn with visible smoke, adopting the "heat-not-burn" method. Relevant studies have shown that at a lower temperature below 500°C, only heating but not burning tobacco, nicotine and some tobacco flavor components can be transferred to the smoke. Compared with traditional cigarettes, low-temperature cigarettes can significantly reduce the release of tar and harmful components as a whole. At the same time, there is basically no sidestream smoke, and the harm to others and the environment is very small.

At present, the low-temperature cigarettes that have been marketed or are being developed in the world mainly include: electric heating low-temperature cigarettes, fuel-heating low-temperature cigarettes and chemical heating low-temperature cigarettes. Electrically heated low-temperature cigarettes use electricity as a heat source to heat tobacco substances to produce nicotine smoke. The fuel heats the low-temperature cigarette, that is, the external fuel block is used as the heat source, and the tobacco substance is heated to produce nicotine smoke. Chemically heating low-temperature cigarettes, that is, using a chemical reactor as a heat source for heating.

Philip Morris Manufacturing Co. applied for a cigarette product (application number: 89104827.8, application date: 1989-07-21), in which the heat generated by the combustion of a carbonaceous heat source is transferred to the flavor section, thereby producing flavored smoke. The carbonaceous heat source and spice segments are housed in a non-combustible cylindrical hollow ceramic sleeve. Smoking articles produce substantially no spillage of smoke. The heat emitted by the heat source is transferred through convection and radiation. This patent uses carbon rods as the heating source. This heating method is disposable and cannot be reused.

Philip Morris Production Company also applied for a cigarette with at least one electric heater smoking system (application number: 94102530.6 filing date: 1994-02-25) for delivering tobacco aroma to smokers. The cigarette includes : a carrier tube having first and second ends spaced longitudinally from each other and having first and second surfaces, the first surface enclosing a cavity between the first and second ends, the second The surface has an area for abutting against an electric heater; and a layer of tobacco substance layer, which is arranged on the first surface of the carrier tube and produces a smoke delivery in the cavity when heated. The tobacco aroma of the latter, wherein the carrier tube and the layer of tobacco aroma material allow lateral air flow into the cavity, and the patent adopts the method of electric heating.

In addition, for the above-mentioned low-temperature cigarettes, when smoking, the total particulate matter is low during the initial smoking period, but it tends to gradually increase until the end, giving consumers a sense of gradually increasing smoke intensity; the heating chamber adopts an integrated When smoking conventional cigarettes in the traditional heating mode, the smoke is very weak at first, then rises rapidly, and then the smoke volume decreases significantly with the increase of the number of puffs. This is mainly because it uses the first few puffs to reach the optimum temperature, so that the tobacco product produces a high concentration of aerosol, but as the puff progresses, the aerosol is exhausted. Compared with conventional cigarettes, the amount of smoke released is uncontrollable, and the sensory differences between different puff numbers are relatively large, and the sensory characteristics tend to weaken in the later period of smoking. In addition, prematurely heating the unheated part of the cigarette will cause part of the smoke or cause the part of the cigarette to be thermally degraded by heating and change its quality; reheating the previously heated part will cause unpleasant odor or harmful components.
