Description

Low-oxygen heated smoking set

The present invention belongs to the field of non-flammable heated cymbal, and particularly relates to oxygen-depleted heated cymbal assemblies.

Traditional cigarettes have a history of hundreds of years and are integrated into the lives of most smokers. In recent years, as people's living standards improve, issues such as smoking and health, the dangers of secondhand smoking, etc. are being emphasized among people, and the risks caused by traditional tobacco products are becoming increasingly important. On the other hand, with the implementation of the “Framework Convention on Tobacco Control” by WHO, in particular with the gradual expansion of smoking bans in public places worldwide, the environment for the development of tobacco products is facing significant and profound changes, and tobacco Product structure is moving toward diversification and smoke-free development (Xiaobing Cheng, Baojiang Li, Yandong Han. The Development Status of New Tobacco in the World [ J ]. China Tobacco, 2014 (3): 38. ). New tobacco products are increasingly becoming a realistic choice for major multinational tobacco companies to cope with declining sales of traditional tobacco products (Yali Liu, Jinbang Wang, Xinzhang Zhao, et al. Development Status and the Prospect of Heat-not-burn). Tobacco Products [J].Chinese Journal of Tobacco, 2018,24 (4)).

At present, most of the non-combustible heating type cigarettes adopt air as a carrier of smoke to ensure that the tobacco does not burn, and the applied heating temperature is generally lower than that of traditional cigarettes, generally not exceeding 300 ° C, which is a novel non-combustible type. The aroma components of the heating type cigarettes are difficult to completely release, and the amount of smoke is not sufficient, so the cigarettes are difficult to be accepted by traditional smokers. In addition, in order to ensure the circulation of air, most of the cigarette ends of non-flammable heated cigarettes have an open structure, that is, the tobacco pieces or reconstituted tobacco strips are directly exposed to the outside, or there are special air flow channels. connected to the outside atmosphere through, and in the process of taking out the cigarettes, the tobacco residue falls off, which is easy to cause contamination of the smoking set, so that this kind of cigarettes save time to clean the smoking set after use. need to consume

If a closed cinder structure is adopted, the oxygen content decreases along the heating process (because of the displaced effect of fresh smoke on the inside atmosphere). At this moment, even if the heating temperature is increased, the burning phenomenon will not occur, and meanwhile, a situation in which tobacco residues fall and contaminate the smoking set will occur. However, since there is no carrier air flow flowing through the cigarette, smoke movement in a closed cigarette will be difficult.

The Coanda effect, also known as the Coanda effect or wall effect, is the result of a fluid or air stream flowing along an overhanging surface out of the original flow direction due to surface friction as fluid flows through the wall of an object. means tendency. The Venturi phenomenon refers to a low pressure generated near a high-velocity flowing fluid, and refers to adsorption accordingly. Using the Coanda effect, air entering the small hole can flow along the surface of the hollow smoke extraction cone. Because of the existence of the Venturi phenomenon, gas flowing at high velocity along the surface of the extraction cone will form a negative pressure region at the opening of the extraction cone. By using the Coanda effect and the Venturi phenomenon, a concentration difference and a pressure difference can be formed inside and outside the closed tobacco area, and then the fresh smoke produced in the tobacco area uses the active diffusion of gas. can be extracted.

In order to meet the public's smoking habits for cigarettes, a smoke extraction structure is required to be used in each cigarette, which can greatly increase the production and manufacturing cost of cigarettes. If the smoke extraction structure is separated and reused, the production cost of the cigarettes will be effectively saved.

Example 4

The smoking method using the above-mentioned oxygen-depleting heated cymbal assembly includes the following steps: during smoking, separating the tobacco region 1 and the filter tip region 3 of the oxygen-depleting heated cymbal, and respectively assembling them into the sleeve region 2-1-5 and the inner diameter expansion region 2-2-3 at both ends of the smoke extraction region 2 to form a region-shaped cigarette (see Figs. 1 and 2) ; then removing the cap (6) of the oxygen-depleting heated smoking set, inserting the cigarette region (1) of the region-shaped cigarette into the cigarette receiving cavity (4-1) of the heating section (4), cap Closing (6) again, and operating the heating element disposed on the side wall of the bottom surface and/or the circumference of the clam receiving cavity 4-1 for suction. 9 and 10 may be referred to for specific use conditions.

Cigarettes and heated smoking sets of the present invention can be stored separately from each other when stored in the factory, where the tobacco section 1 and the filter tip section 3 are individually wrapped, and then connected and bonded together. (see Fig. 8), and the heated smoking set and the smoke extraction area 2 are connected together, and can be used repeatedly (see Fig. 11); When smoking, first the tobacco area 1 is separated from the filter tip area 3, and the tobacco area 1, the smoke extraction area 2 and the filter tip area 3 are sequentially inserted into the area for smoking- Area-shaped cigarettes for forming, and then smoking, are inserted into a heated smoking set (see Figs. 9 and 10); It should also be noted that after smoking the tobacco area 1 and the filter tip area 3 are discarded, and the heated smoking set and smoke extraction area 2 can be reused. The structure of an oxygen-depleted heated smoking set in storage is shown in FIG. 11 .

During smoking (inhalation), air first enters the space between the cap 6 and the area-shaped cigarette, then enters the smoke delivery pipe through the through hole 2-2-2 on the pipe wall of the smoke delivery pipe and , and sprayed onto the surface of the extraction cone. Because of the Venturi effect and the Coanda effect, a negative pressure is formed at the location of the taper hole 2-1-4; Heating the tobacco area can create a positive pressure in the tobacco area; The pressure difference between the positive pressure and the negative pressure causes the smoke to flow, causing the smoke to flow out of the taper hole 2-1-4, and through the smoke delivery pipe cavity and filter tip into the cavity of the oral cavity. The smoke delivery pipe has the dual function of smoke extraction and smoke cooling. The smoke resistance of the cigarette can be adjusted by changing the diameter and position of the through hole 2-2-2 of the smoke delivery pipe.
