The present disclosure relates to the technical field of novel tobacco, and in particular, to an electric heating cigarette appliance capable to adjust the temperature and the period.
Traditional cigarettes can emit smoke due to the burning of tobacco and wrappers that may occur at temperatures exceeding 800 degrees Celsius during smoking. At such high temperature, the tobacco is thermally degraded due to pyrolysis and combustion, resulting in various gaseous combustion products and fractions from tobacco, it not only produces taste and aroma, but also produces many undesirable compounds.
The existing commonly used electric heating cigarette appliances are separated and include a charging case and/or a heating rod. The charging case is used to charge the heating rod, and the smoke-forming substrate is heated by the heating rod. However, in the prior art, the heating temperature and heating period of the heating rod are fixed after the manufacture is completed, and the user cannot adjust the heating temperature and heating period of the electric heating cigarette appliance.
There is a need for low-temperature cigarettes to produce stable and comfortable smoke. However, in the electric heating cigarette appliances in prior art, it is difficult to be realized because the generation of smoke is related to the material of the substrate and the temperature of the heating substrate. The changes of the smoke-forming substrate or the heating temperature can significantly change the quality of the smoke, thereby reducing the fragrance, taste and mouthfeel experienced by the user.
In addition, even if the smoke-forming substrate does not change, the electric heating cigarette appliance with a fixed heating temperature and heating period in prior art is difficult to produce stable and comfortable smoke because of changes in ambient temperature, such as winter and summer. Due to the large change in ambient temperature, under the same heating rod working temperature and/or working period, the comfort experience of the generated smoke will also be greatly affected, thereby affecting the taste of smoking.
The purpose of the present disclosure is to overcome the above-mentioned drawbacks and overcome the problem that the heating rod in the prior art only works at a constant temperature and/or in a constant heating period, so that it can work under different substrates and/or different ambient temperatures. It is provided that an electric heating cigarette appliance that provides the best stable and comfortable smoking experience.
