Description

Sealed heating device with lower oscillating magnet

Technical Field

The utility model belongs to the technical field of heating device, in particular to sealed heating device of oscillating magnet undermount and application method thereof.

Background

The existing non-burning type cigarette is heated directly or indirectly, and aerosol generated after heating the cigarette is sucked into the mouth of a smoker to form smoke by taking air flow passing through the cigarette as a carrier during smoking. In order to ensure that the tobacco segments do not burn, the tobacco rod is generally heated to a temperature not exceeding 300 ℃. Compared with the traditional cigarette, the cigarette which is not burnt by heating has no harmful components such as tar and the like generated during burning, but the tobacco aroma components are difficult to completely release, so the cigarette is difficult to be accepted by the traditional smokers.

If the smoking set adopts a closed cigarette heating structure with the end not being filled with air (namely, no air inlet gap is formed between the cigarette and the cigarette accommodating cavity), when the cigarette with normal ventilation (the two ends of the cigarette are normally ventilated) is inserted into the closed cigarette heating structure, the oxygen content of the tobacco section can be reduced along with the heating process, which is because the newly formed fresh smoke has the replacement effect on the gas in the cigarette. When the heating temperature is gradually increased, the cigarette can not be burnt, meanwhile, the tobacco in the cigarette and the air carried by the tobacco in the cigarette are rapidly heated to the working temperature of the smoking set from the ambient temperature, the internal gas pressure is increased, and the tobacco aroma components of the tobacco are discharged out of the smoking set together with the high-pressure gas to form smoke aerosol.

However, as the heating element continues to heat the cigarette, the heat increases rapidly during the temperature rise from room temperature to the beginning of smoking. When the heating element reaches the working temperature, the temperature is not increased any more, and the increment of the overflow of the aerosol of the smoke in the cigarette accommodating cavity is not as high as that in the temperature rise stage. Because there is no continuous flow of air through the tobacco segment, the natural outflow of smoke aerosol is significantly insufficient by pressure differentials or by the action of the filter portion of the cigarette, resulting in the problem of insufficient smoke after about 1/5 has been smoked for one cigarette.

In order to solve the above problems, a utility model is provided.
