Technical Field

The invention belongs to the technical field of heating devices, and particularly relates to an inverted smoking heating device, a cigarette system and a smoking method.

Background

Traditional tobacco has been in the past for centuries and has been incorporated into the lives of most smokers. In recent years, along with the improvement of living standard of people, the problems of smoking, health, harm of second-hand smoke and the like are more and more emphasized by people, and the harmfulness brought by the traditional tobacco products is more and more prominent. The new tobacco products are not combusted, so that the new tobacco products gradually become a realistic choice for various large international tobacco enterprises to deal with the sales volume of the traditional tobacco products.

At present, most of heating cigarettes adopt air as a carrier of smoke, in order to ensure that tobacco does not burn, the applied heating temperature is usually lower and generally does not exceed 300 ℃, compared with the traditional cigarette, the tobacco aroma components of the novel heating cigarette are difficult to completely release, and the smoke quantity is insufficient, so that the cigarette is difficult to be accepted by traditional smokers. In addition, in order to ensure air circulation, most of the tobacco ends of the heated cigarettes are in an open structure, namely, the cut tobacco or the reconstituted tobacco sheets are directly exposed outside or are connected with the outside atmosphere through a certain airflow channel, and tobacco residues can drop and easily pollute the smoking set in the process of pulling out the smoke bomb after smoking is finished, so that the smoking set is cleaned by the tobacco in a certain time.

If a closed cigarette structure is adopted, the oxygen content is reduced along with the heating process (due to the replacement effect of the formed fresh smoke on the internal atmosphere), at the moment, even if the heating temperature is increased, the combustion phenomenon can not occur, and meanwhile, the situation that the tobacco residues fall to pollute the smoking set can not occur. However, closed cigarette smoke migration would be difficult because no carrier gas is flowing through the tobacco.

Currently, an oxygen-deficient heating smoking set with retractable needles, and a tobacco product used with the same, are disclosed in application No. CN202010422669.5 to solve the above problems. However, the inventors found that the following problems still remain:

1. the tobacco products disclosed in the above patents require perforations in the side walls of the hollow section, which is the cavity formed by the mainstream smoke of the cigarette, and this requires the use of special perforation equipment, and therefore, the batch operation is inefficient.

2. The hollow section material of cigarette and the material of extranal packing are all paper generally, make these paper take place the deformation easily when punching, influence pleasing to the eye.

3. After the hollow section of the cigarette is punched, the contact area of the hollow section of the cigarette with the outside air is increased, so that the cigarette is easily affected with damp or polluted by the outside air in the storage process.

4. Because cigarette length is fixed, cigarette hollow section length also is fixed, therefore the regional scope that can punch is certain, can't adjust the position of lateral wall through-hole at will.

5. During the suction, the user lip contacts with a cigarette filter tip, and inevitable can make a cigarette take place the displacement, if a cigarette relies on the cooperation with the smoking set and seals, influences the sealed effect of a cigarette tobacco section easily.
