Description

A non-burning tobacco smoking device based on microwave heating

technical field

The invention relates to an appliance used in the field of heating non-combustion tobacco, in particular to a non-combustion tobacco smoking device based on microwave heating.

Background technique

Microwave heating is to generate "internal friction heat" through the high-frequency reciprocating motion of dipole molecules inside the heated body to increase the temperature of the heated material. Without any heat conduction process, the inside and outside of the material can be heated at the same time, and the temperature can be raised at the same time. The speed is fast, and only a fraction or a few tenths of the energy consumption of traditional heating methods can be used to achieve the heating purpose. Microwave heating has been widely used in people's daily life at present. Such as household microwave ovens, microwave vacuum dryers, etc., have the characteristics of energy saving, high efficiency, and no pollution.

With the continuous deepening of the global tobacco control campaign, the research and development of new tobacco products has been paid more and more attention. Various new tobacco products, such as bagged mouth tobacco products, chewing tobacco and snuff, have been launched and have occupied a certain market share. The biggest advantage of the product is that there is no smoke formed by combustion during use, and there will be no "second-hand smoke" hazards, and there will be no hidden dangers such as fire. However, based on the long-term consumption habits of smokers, they still have a soft spot for the conventional smoking methods of tobacco. Therefore, a tobacco that can not only meet people's smoking consumption habits, but also avoid open flames caused by tobacco burning and reduce the harm of "second-hand smoke" has been developed. The suction device has attracted the attention of researchers in the industry. A Chinese patent discloses a "blending additive for atomizing tobacco smoke after heating, its use method and tobacco composition", the patent application number is 201210267881.4, which discloses a tobacco heater, which is placed in an oven The heating sheet heats tobacco and blends additives, and then smokes and enjoys tobacco. Its tobacco heating method is electric heater heating, and no other heating methods are mentioned. The patents "Electric Smoking System and Cigarettes for Delivering Cigarettes and Cigarettes" (Patent No. 94102530.6) and "Heater Used in Electric Smoking Appliances and Its Manufacturing Method" (Patent No. 95190277.6) applied by Philip Morris in China also use electric heating. Way.

Contents of the invention

The object of the present invention is a non-combustion tobacco suction device based on microwave heating designed based on the above-mentioned existing technical conditions. smoke-free smoking appliances.

The object of the present invention is to adopt the following technical solutions: a non-combustion tobacco suction device based on microwave heating, comprising a metal casing, a smoke sample heating unit arranged at the center of the metal casing, and a smoke sample heating unit placed between the metal casing and the smoke sample heating unit There is an air flow channel, and the smoke sample heating unit is provided with a battery, a microwave heater and a ceramic smoke sample cup in sequence from front to back. The front end of the metal case.

In the invention, a filter piece is added in the filter tip, and the filter tip and the casing are connected by thread or inserted, so the combination is very convenient.

The heating temperature in the ceramic smoke sample cup is 100-500 ℃, and the heating objects are different forms of tobacco materials such as tobacco leaves, tobacco flakes, and tobacco extracts.

When the present invention is used, different forms of tobacco materials such as tobacco leaves, tobacco flakes, and tobacco extracts are put into the ceramic smoke sample cup, the power switch is turned on, and the microwave generator is turned on to heat the smoke sample. After heating, the microwave generator is turned off , The volatiles produced in the smoking cup enter the oral cavity through the through holes on the side wall of the ceramic smoking cup, the airflow channel, and the filter, so that the smoker can get a sense of satisfaction.

The biggest feature of the present invention is: energy saving, high efficiency, no pollution, uniform heating and fast heating, suitable for indoor use, and convenient for going out and outdoor use. It not only conforms to people's smoking consumption habits, but also avoids open flames caused by tobacco burning, is environmentally friendly and pollution-free, and can reduce the harm of "second-hand smoke", so it has potential market competitiveness.
