Technical Field

The invention relates to the technical field of cigarette cartridge manufacturing, in particular to a manufacturing method of an environment-friendly wrapping-free heating non-combustion naked cigarette cartridge.

Background

Smoking is a common recognition of people, and a great deal of research proves that after the cigarette is ignited, various substances harmful to human bodies such as aldehydes, nitrides, olefins, nicotine and the like can be generated. Therefore, the development of a novel tobacco product which can greatly reduce the release amount of harmful ingredients in tobacco gradually becomes the key development point of the tobacco industry of all countries in the world. At present, a plurality of non-burning smoking tobaccos are released in the market, and the tobacco shreds are heated and baked at a lower temperature by means of a heating smoking set to generate smoke, so that aroma components in the tobacco shreds are volatilized, and the process of smoking cigarettes is achieved.

CN110101128A relates to a heating non-combustion tobacco, which comprises a filtering section and a heating section which are connected into an integral structure; the filter section is a fiber filter stick; the heating section comprises a tobacco part and an outer cigarette paper layer; the tobacco part consists of a loading matrix and tobacco microcapsules; the loading substrate is in a round tube-shaped structure, and the tobacco microcapsules are adsorbed in the loading substrate or arranged in a cavity in the side wall of the loading substrate. The heating section of the cigarette which is not combusted by heating is set to use a loading matrix and loading microcapsules, the microcapsules loaded with tobacco extracts or other characteristic substances and smoke agents are loaded on the loading matrix, and the finished product heating section is prepared by coating the tobacco extracts, adhesives and other characteristic auxiliary materials in a high proportion compared with the traditional heating section.

CN111329121A discloses a heat non-combustible cigarette comprising a fastening member, a heat non-combustible cigarette body, a tobacco sheet section and a rolling material member, wherein the fastening member has a butt end, wherein the heat non-combustible cigarette body is mounted to the fastening member, wherein the tobacco sheet section is mounted to the butt end of the fastening member, wherein the fastening member, the heat non-combustible cigarette body and the tobacco sheet section are wrapped around the rolling material member, wherein the rolling material member is implemented to be made of air permeable sheet material.

CN111418904A provides a heating non-combustion cartridge, which is composed of a tobacco regenerated material for heating non-combustion and a packaging shell. The packaging shell comprises a cigarette bullet cup and a cigarette bullet cover, the cigarette bullet cup comprises an opening end face of the cigarette bullet cup, a side wall face of the cigarette bullet cup and a bottom end face of the cigarette bullet cup, and the cigarette bullet cup is provided with an air inflow port. The cigarette bullet lid is including cigarette bullet lid top end face and cigarette bullet lid lateral wall, and cigarette bullet lid top end face is equipped with the flue gas outflow hole. The cigarette bullet cover is embedded and fixed in the cigarette bullet cup through the clamping and embedding matching with the opening end surface of the cigarette bullet cup. By adopting the structure, adverse chemical reactions generated by heating, gluing and the like and adverse effects on tobacco contents are avoided, accessories such as sealing gaskets are avoided, the production cost is greatly reduced, and the processing efficiency is effectively improved.

Although the research on the non-combustible smoke bomb exists in the prior art, the non-combustible smoke bomb is heated in the prior preparation process, the smoke formed during smoking is obvious, and the smoke is easy to volatilize to influence the surrounding environment; the volatilized smoke carries a large number of harmful, irritating particles; meanwhile, the preparation method has the defects that the working procedures and the cost are not favorable for commercial application, for example, the manufacturing process of the cigarette bullet is complex, the structure of the cigarette bullet is complex, each structural component in the cigarette bullet contains non-degradable materials (such as a filter tip rod, a blocking piece and the like) which are harmful to the environment, and the components in the cigarette bullet can volatilize certain harmful substances after being heated at high temperature and are easy to be absorbed into the body. In addition, the cartridge/cigarette consumes a large amount of paper tubes or tipping paper for wrapping, the production cost is high, and a large amount of natural resources such as wood and the like are consumed.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide an environment-friendly wrapping-free heating and non-combustion bare smoke bomb so as to solve the technical problems that smoke of the existing smoke bomb is mixed with harmful substances, the structure is complex, the cost is high and the environmental pollution is easily caused.

Heating the tobacco material during smoking of the cartridge produces a particulate form in which some chemicals (including products formed by chemical reactions at high temperatures of organic or inorganic substances) are aggregated, e.g. the particles typically contain NH₄ ⁺The particles of the active groups are in aerosol form, usually not exceeding 10 μm in size, such as COx, SOx, NOx, nitrosamines, nitrogen heterocycles, cyclic ketones, quinones, phenols and acids. These harmful particles tend to aggregate when they approach each other, and form aggregates, which are mixed in smoke and volatilized. The volatilized smoke can be directly inhaled into the body by consumers and other organisms in the same environment, and harms are generated to the body; meanwhile, the smoke particles can absorb other water-soluble particles generated in the environment, such as sulfate, nitrate, ammonium salt, Volatile Organic Compounds (VOC), polycyclic aromatic hydrocarbon and toxic substances, and further damage to the health of consumers and the environment is aggravated. In addition, the smoke mixed with these harmful group particles also produces a nausea and irritating odor, which is unpleasant to use.

The inventor aims to solve the problems and adds an inhibitor for regulating the aggregation of active group particles into the smoke bomb, wherein the inhibitor coats the surface of the organic group particles when the smoke bomb is heated, captures free radicals of the active particles (such as OH-, H + and dense aromatic hydrocarbon) and makes the free radicals on the surface lose activity, thereby preventing the aggregation of harmful particles and preventing the harmful particles from being mixed in smoke and volatilizing. Preferably, the inhibitor is selected to be an alkylated ester with polar groups, such as glycerol triacrylate, glycerol trimethacrylate, pentaerythritol tetraacrylate, or a combination thereof. The effect of naked cigarette can be well realized by using the cigarette bomb added with the inhibitor. The inhibitors are selected to be capable of combining with free radicals on the surfaces of active particles well, and are diffused, adsorbed and coated on the surfaces of the active particles before the active particles are aggregated to be smoke volatilized, and polar groups contained in the inhibitors cut the aggregated or prone-to-aggregate active particles into monodisperse particles due to repulsion.

Meanwhile, the cigarette cartridge of the invention does not need a paper tube, a filter tip and a blocking piece required by the traditional cigarette, and adopts a naked cigarette cartridge, thereby reducing the difficulty of the production process, reducing the use of raw materials and being more environment-friendly. Compared with a naked cigarette, the cigarette has abundant smoke quantity, good aroma quality, soft and exquisite smoke, no unpleasant firewood smell and miscellaneous gas, small irritation, comfortable aftertaste and better user experience.

[ evaluation of smoke component ]

After the cartridge is burned or heated, the smoke is emitted. The smoke contains a large amount of chemicals which can be mixed with harmful particles or organic substances and can cause harm to the environment and people around the environment. According to the invention, the particle aggregation inhibitor is added into the smoke bomb, so that the effect of reducing the content of harmful substances in the discharged smoke is achieved. The effect of suppressing harmful substances in the exhaust fumes of examples 1 to 4 was evaluated.

The principle of the evaluation method is to evaluate the progress analysis of the smoke generated when the cigarette cartridge is heated. The method adopted is a gas chromatography-mass spectrometry (GC/MS) method for composing cigarette smoke. The smoke is formed, and the particle fog is gathered to form visible smoke to be displayed. The tested particulate matter comprises the following main components:

amine-containing compounds (i.e., N-ring compounds), such as nitrosamines, aromatic amines, heterocyclic amines, and the like, primarily carcinogens;

alkanes, hydrocarbons, and also carcinogens;

other free radicals are absorbed into the body to accelerate the oxidation reaction of the human body and destroy the body function;

heavy metal particles, such as lead, etc., destroy the functions of the human body;

other components, such as carbon monoxide, nitrogen oxides, sulfur-containing gases, are harmful to both the air and the human body.

The existing incense standard mainly comprises GB26386-2011 general technical conditions for safety of incense products and GB/T26393-2011 test methods for harmful substances of incense products.

Chromatographic conditions are as follows: a chromatographic column: rxi-1ms quartz capillary column (30 m.times.0.25 mm.times.0.25 μm); temperature rising procedure: keeping at 50 deg.C for 0min, heating to 150 deg.C at 10 deg.C/min for 3min, heating to 280 deg.C at 7 deg.C/min, and keeping for 10 min; column flow rate: 1.0 mL/min; and (3) sample introduction mode: split-flow sample injection is carried out, and the split-flow ratio is 5: 1.

The method for collecting the burning incense smoke simulating the actual environment is to arrange a sampling point in a sealed glass square box with the volume of 1.8m multiplied by 1.8m according to the 7 th test condition in the standard GB/T26393-2011 'testing method for harmful substances of burning incense products', and the collection is completed within 40 min; three sampling points with different distances are arranged in a sealed glass square box with the center as the origin point and collected in the sealed glass square box with the diameter of 1.8m multiplied by 1.8m, namely a central point, a farthest point and a radius point. The result shows that the detection results of different acquisition points have little difference, and the detection data of the central point is more stable. Therefore, the present invention selects the center point as the acquisition point. After the smoke samples of the examples and comparative examples were collected, they were carried into the column by an inert gas (i.e., carrier gas) and adsorbed. The final results (main chemical components) of the test are shown in table 2 below.

TABLE 2

Table 2 shows the results of the composition analysis of the smoke generated by heating the cartridge. Tests show that compared with the heating of a commercial sample smoke bomb, the content of irritant harmful substances such as aromatic hydrocarbon, amine, heavy metal, oxide and the like in the smoke discharged by the smoke-discharging device is reduced by 20%.

Meanwhile, the composition analysis is carried out on the smoke generated by heating the smoke bomb, and tests show that compared with the heating of a commercially available smoke bomb, the content of the irritant harmful substances such as ammonia, carbon monoxide, nitric oxide, aromatic hydrocarbon and the like in the smoke discharged by the smoke bomb heating device is reduced by 20%.

Compared with the prior art, the environment-friendly wrapping-free heating non-combustion naked cigarette bomb prepared by the method has the advantages that in order to prevent harmful substances from gathering and volatilizing, the particle inhibitor is added into the components for adjustment, so that the content of the harmful substances in smoke can be effectively controlled; meanwhile, the cigarette cartridge does not need a paper tube, a filter tip and a blocking piece required by the traditional cigarette, and adopts a naked cigarette cartridge, so that the difficulty of the production process is reduced, the use of raw materials is reduced, and the cigarette cartridge is more environment-friendly. Compared with a naked cigarette, the cigarette has abundant smoke quantity, good aroma quality, soft and exquisite smoke, no unpleasant firewood smell and miscellaneous gas, small irritation, comfortable aftertaste and better user experience.

Compared with the prior art, the manufacturing method of the environment-friendly wrapping-free heating non-combustion naked cigarette bomb adopts the main body, the sealing cover lining and the closing piece to form the leather shell with a good supporting effect together, and meanwhile, the main body, the sealing cover lining and the closing piece can be processed in a standardized mode, so that the purpose of large-scale industrial mass production is achieved.
