In the invention, the color-changing particles are arranged in the transparent cavity filter stick, and the color change process of the particles can be visually seen. For example, when a cigarette is smoked, people can visually see the color change process of the discoloring particles containing the thermochromic material, which is caused by the temperature change of burning smoke, or can visually see the color change process of the discoloring particles containing the photochromic material, which is irradiated by external light through the wall of the transparent cavity filter stick, or can visually see the color change process of the discoloring particles containing the pH photochromic material due to the influence of the pH value of the smoke.
According to YC/T138-1998 tobacco and tobacco product sensory evaluation standards, a smoking group consisting of 15 smoking experts is organized to smoke cigarettes containing the color-changing particles for cigarettes, meanwhile, the same cigarettes without the color-changing particles for cigarettes are also smoked, and the smoking results are shown in the detailed embodiment part.
Advantageous effects
The invention has the beneficial effects that: the color-changing particles for the cigarettes are always in a dry and flowable state, are free from adhesion, do not collapse due to heat, and do not block the circulation of smoke. The novel sensory experience is brought to the smokers while the smoking experience of the smokers is not influenced, and the preparation method is simple, low in cost and suitable for industrial production.
