Description
Technical Field
The invention belongs to the field of heating non-burning cigarettes, and particularly relates to an oxygen-deficient heating type cigarette component.
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. Meanwhile, with the implementation of WHO "tobacco control framework convention", especially the gradual expansion of smoking ban in public places of all countries in the world, the development environment of tobacco products has changed significantly and profoundly, and the structure of tobacco products is rapidly adjusting toward the development direction of diversification and smokelessness (dawn, li bajiang, han yandong. world new tobacco development [ J ]. chinese tobacco, 2014 (3): 38). The new tobacco products gradually become the realistic choice for various large transnational tobacco enterprises to deal with the increasing decline of the sales volume of the traditional tobacco products (Liu Yali, Wang jin rod, Zheng Xin Chao, etc.. the development status and the prospect of heating the non-combustion tobacco products [ J ]. Chinese tobacco academic newspaper, 2018,24 (4)).
At present, most of the non-combustible heating cigarettes adopt air as a carrier of smoke, in order to ensure that the tobacco is not combusted, 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 non-combustible 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 cigarettes which are not heated and combusted 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 off 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 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.
The coanda effect, also known as coanda effect or coanda effect, means that when a fluid flows over a surface of an object, the flow of the fluid water or air tends to move away from the original direction of flow instead following the surface of the protrusions due to the surface friction. The venturi phenomenon is a phenomenon in which low pressure is generated in the vicinity of a fluid flowing at a high speed, thereby generating an adsorption effect. The air entering the small hole can flow along the surface of the smoke extraction cone by utilizing the coanda effect; due to the venturi phenomenon, the gas flowing along the surface of the extraction cone at high speed forms a negative pressure area at the opening of the extraction cone. By utilizing the coanda effect and the Venturi phenomenon, concentration difference and air pressure difference can be formed at the downstream of the closed tobacco section, so that fresh smoke generated by the closed tobacco section is extracted.
In order to meet the smoking habit of the public for cigarettes, a smoke extraction structure is required to be used in each cigarette, which greatly increases the production and manufacturing cost of the cigarette. If the smoke extraction structure is independent, the repeated utilization is realized, and the production cost of the cigarette can be effectively saved.

See fig. 9 and 10 for a specific use state.
It should be further noted that the cigarette and the heating smoking set are separately placed when being delivered from the factory, wherein the tobacco section (1) and the filter tip section (3) are respectively wrapped and then are connected and placed together (see fig. 8), and the heating smoking set and the smoke extraction section (2) are combined together and placed for reuse (see fig. 11); during smoking, the tobacco section (1) is separated from the filter tip section (3), the tobacco section (1), the smoke extraction section (2) and the filter tip section (3) are sequentially spliced to form a sectional type cigarette to be smoked, and then the sectional type cigarette to be smoked is inserted into a heating smoking set (see the figures 9 and 10); the tobacco section (1) and the filter section (3) are discarded after smoking, the heating smoking set and the smoke extraction section (2) can be reused, and the structure of the oxygen-deficient heating smoking set is shown in figure 11 when being stored.
During suction, air firstly enters a space between the cap 6 and the sectional type cigarette, then enters the smoke transmission pipe through the through hole (2-2-2) on the pipe wall of the smoke transmission pipe and is sprayed to the surface of the extraction cone, and negative pressure is formed at the position of the cone hole (2-1-4) due to the Venturi effect and the coanda effect; heating the tobacco segment creates a positive pressure in the tobacco rod portion; the existence of the positive and negative pressure difference can cause the smoke to flow, so that the smoke flows out of the taper holes (2-1-4) and enters the oral cavity through the smoke conveying pipe cavity and the filter tip. The flue gas transmission pipe has the dual functions of flue gas extraction and flue gas cooling. The smoking resistance of the cigarette can be adjusted by changing the diameter and the position of the through hole (2-2-2) on the smoke conveying pipe.
