Smoke generating device for induction heating at front end of cigarette

Abstract

The invention belongs to the field of novel cigarette smoking sets, and particularly relates to a smoke generating device for induction heating at the front end of a cigarette. The smoke generating device comprises a hollow heating cup (2), a heating body (5) and an induction coil (4), A hollow heating cup (2) comprises an upper hollow structure, a lower hollow structure and a baffle between the upper hollow structure and the lower hollow structure; a heating body (5) is arranged in the lower hollow structure, and an induction coil (4) is arranged on the periphery of the heating body (5); andthe heating body (5) is made of ferromagnetic metal and has a structure through which air can pass. According to the invention, the smoke generating device for induction heating at the front end of the cigarette is designed for the first time, and a plurality of airflow channels are formed inside and/or on the surface of the heating body, so that air flowing through the surface of the heating bodycan be quickly and fully heated; the problems that an existing electric heating cigarette is uneven in heating, a carbon heating cigarette is easy to roast and burn and not easy to control, aroma components are insufficient, and smoking feeling is poor are effectively solved.

Description

technical field [0001] The invention belongs to the field of novel cigarette smoking sets, and in particular relates to a smoking device for inductively heating the front end of a cigarette. Background technique [0002] With the improvement of people's health awareness, heat-not-burn cigarettes are more and more popular among smokers because they are less harmful than traditional burn-and-smoke cigarettes. At present, the heating methods of heat-not-burn cigarettes include: contact electric heating, non-contact electric heating, charcoal heating, etc. [0003] Contact electric heating refers to direct contact heating of cigarettes to obtain smoke, which uses various forms of heating appliances such as tubes, needles or plates for electric heating to directly contact with cigarettes or shredded tobacco, at a temperature lower than the ignition point of cigarettes. The cigarette or tobacco is directly contacted and baked to volatilize the aroma components and smoking compone...

AI Technical Summary

Problems solved by technology

[0005] 1. The shredded tobacco that is in direct contact with the cigarette or shredded tobacco can be fully toasted, while the shredded tobacco that is a little far from the heating element cannot be toasted sufficiently, and the toasting effect has certain differences on the circumferential cross section of the cigarette. Uniformity;

[0006] 2. The heating appliance itself is small in size and its heat capacity is not high

But at the same time, the problem is that after the tobacco in contact with the heating element is heated several times, the cured tobacco substance will stick to the heating element, which will bring peculiar smell or heating difficulty to the subsequent cigarettes.

Although this kind of charcoal-heated cigarette has the characteristics of lower harm than the existing ordinary cigarettes, the front end of the cigarette is attached with a carbon rod, which not only increases the difficulty of cigarette manufacturing, affects production efficiency, but also causes consumers to ignite the charcoal rod. It takes a long time, it is not easy to ignite, and the charcoal rod may have some disadvantages such as peculiar smell wh...
