Description

Fuming particles with multi-layer structure, preparation, use method and use thereof {MULTILAYER STRUCTURE SMOKING PARTICLE, ITS PREPARATION, USE METHOD AND APPLICATION}

The present invention belongs to the field of heated cigarette technology and particularly relates to multi-layered fuming particles, their manufacture, methods of use and uses.

As more and more people pay attention to their health problems with the improvement of living standards, interest in health problems caused by smoking has increased in recent years. Major domestic and foreign companies are developing various new products to replace traditional cigarettes to meet changing consumer needs. Among the ever-increasing number of new cigarette products, e-cigarettes and heated cigarettes are the best of the two.

Electronic cigarette is an extended application of electronic products in the cigarette industry. Its biggest advantage is that it has excellent inhalation variability and can arbitrarily control smoke inhalation by adjusting the liquid phase, but since smoke is mainly generated through an electronic atomizer, the taste, especially Smokers' preference is low because it is different from traditional cigarettes that generate smoke by heating the heat sensation.

The heating type cigarette generates smoke by heating the smoking core material section of the cigarette, and the taste of the smoke thus produced is relatively good. For several years, the efforts of major domestic cigarette companies have led to the emergence of new heating products using particles as a base material for smoke. However, since the particles easily absorb moisture, lumps are formed, which affects smoke, and the particle material itself has a certain adsorption effect on smoke, there is a problem in that the amount of smoke is small.

Therefore, the present invention is provided to solve the above problems.

In order to solve the problems of the prior art, the present invention provides fuming particles having a multi-layer structure, and methods for manufacturing, using, and using the same.

In a first aspect, the present invention provides a multi-layer structured fuming particle, wherein the fuming particle (1) includes at least an inner core layer (11), a fuming layer (12), and a coating layer (13) from the inside to the outside;

the inner core layer 11 includes micropores, mesopores, and macropores, the diameter of the micropores is less than 2 nm, the diameter of the mesopores is 2 to 50 nm, and the diameter of the macropores is greater than 50 nm;

The smoke layer 12 includes a solid substrate, a flavoring agent, and a smoke agent.

Preferably, the specific surface area of the inner core layer 11 is 180 to 450 m ² /g. This is because the smoke amount is greatly reduced when the specific surface area of the inner core layer 11 is excessively small or large. Since mist condensation nuclei can be well provided in the pores when initially sprayed within this range, energy required for initial spraying can be reduced, and this action is similar to preventing bumping by putting zeolite in the heating liquid.

Preferably, the specific surface areas of the micropores, mesopores, and macropores are distributed as follows: micropores/mesopores = 1/1 to 1/2, mesopores/macropores = 2/1 to 4/1. This is because the distribution of the specific surface area of the micropores and macropores that are excessively large may reduce the smoke amount. If the micropores are excessively large, the amount of heat during heating can be dispersed, so that smoke is slowed down. The amount of smoke is reduced. The entire smoking process starts with the formation of the condensation nuclei in the micropores, and can be smoothly transported to the macropore region through the mesopores. The role of the macropores mainly has another aspect. That is, (1) the inner core layer 11 has a certain roughness so that the smoke layer 12 is well coated on the inner core layer 11, (2) the condensation core layer is formed at this point, the smoke layer ( After being contacted with the smoker, the spice mixture, and the spice of 12), a mist is formed by penetrating the smoker layer 12 in a way that quickly grows and breaks through forcefully.

In the present invention, the particle size of the inner core layer 11 is not specified, and the particle size of the final fuming particles 1 is also not specified. The main factors affecting the smoke emission are the specific surface area of the inner core layer and the ratio distribution of voids. Preferably, the particle diameter of the inner core layer 11 is 20 to 40 mesh. Of course, other particle diameter ranges are possible, and even if they are larger or smaller, they can be corrected when loaded into the smoke layer, and the difference in the size of the final particles is not large, which has a slight effect on the smoke effect, but the difference in deviation is not large. .

Preferably, since the melting point of the coating layer 13 is less than 300° C., it may be melted first when heated, and an excessively high melting point may prevent smoke from being emitted. The material of the coating layer 13 is one or more types of polymer films having non-toxic and odorless properties such as sodium alginate, polylactic acid (PLA), and polysaccharides. The coating layer 13 mainly serves to prevent the particles from being absorbed into water during storage and to prevent lumps from being formed between the particles.

Preferably, the inner core layer 11 is selected from one or both of natural and synthetic materials. The inner core layer 11 may be made of activated carbon having a specific pore structure, molecular sieve, or a modified natural ore material.

Preferably, the smoke layer 12 includes at least one sub smoke layer, the solid material in the two adjacent sub smoke layers is the same or different, and the spice in the two adjacent sub smoke layers. are the same or different, and the smokers are the same or different in the sub-flaming layers of the adjacent two layers. Preferably, the smoker is composed of one or both of glycerol and propylene glycol.

Preferably, the solid substrate is selected from at least one of plant roots, stems, and leaves in powder form, examples of which include kudzu root, leaf sheath, peppermint leaf, cigarette stem, and agarwood.

Preferably, the moisture content of the smoke layer 12 is 8 to 22%. If the moisture content is excessively low, the production difficulty increases and it is difficult to realize, and the effect of improving the smoke of the particles is also not clear. On the other hand, if the moisture content is excessively high, the amount of mist greatly decreases, and at the same time, a problem that can cause burns to the mouth due to smoke may occur.

In the second aspect, the present invention provides the method for producing the fuming particles described in the first aspect, which includes the following steps:

Step (1) of manufacturing the inner core layer 11 by subjecting the inner core material to high-temperature degassing, reduced-pressure degassing, or high-temperature reduced-pressure degassing to obtain the inner core layer 11;

A step in which the prepared solid base material, the spice mixture and the spice, and the smoke-flavoring agent are loaded onto the inner core layer 11 obtained in step (1) and dried to obtain coarse particles. (2);

If the smoke layer 12 is a sub smoke layer larger than one layer, the above step (2) should be repeated up to the number of designed layers;

Step (3), which is the coating process of the coating layer (13), in which the coating material is dissolved in a solvent, and the fuming particles (1) are obtained by coating the coarse particles obtained in Step (2) using a fluid spraying or rolling attachment method; include

The purpose of degassing the inner core material is to remove the volatile substances inherent therein, thereby preventing bad odors generated when heating it.

The loading method in step (2) is determined according to the state of the prepared mixture. If the viscosity is excessively high, a fluid spraying or rolling application method may be used, and if the viscosity is low, dipping may be used.

In step (3), a dip coating method is generally not used to prevent the components of the smoke layer 12 from melting again and overflowing.

Preferably, in step (1), the temperature of the high-temperature degassing is 300° C. or higher, the pressure of the reduced-pressure degassing is 600 mbar or lower, the treatment conditions of the reduced-pressure degassing are that the temperature is 250° C. or higher, and , the pressure is 800 mbar and below;

the degassing time is 30 min or more;

In step (3), it is ideal that the amount of the coating material is 0.5 to 2% of the combined total mass of the inner core layer 11 and the smoke layer 12, and excessive amounts may interfere with smoke.

In a third aspect, the present invention provides a method of using the fuming particles according to any one of the first aspect, wherein the fuming particles (1) are put into a heated cigarette, an electronic cigarette cartridge or a smoking tool for use.

Preferably, the structure of the heated cigarette and the cigarette made of particulate smoking material commonly used today are the same, as shown in FIG. 2 . It includes, in order, a parafilm 21, a fuming core material section 22, a hollow support section 23, a cooling section and a filter section 24, wherein the fuming core material section 22 is the fuming particles (1) is filled with

Preferably, the heating chamber and filter structure of the smoking tool is as shown in Fig. 3, the inside of the smoke chamber is used to accommodate the smoke particles 1, and the upper end of the smoke chamber is the filter of the smoking device. It is connected to section 34. When the smoking implement adopts a circumferential heating method (Fig. 3a), a circumferential heating element 31 is installed on the side wall of the smoking chamber. When the smoking implement adopts the microwave heating method (FIG. 3C), a microwave generating element 33 is installed on the side wall of the smoke chamber. When the smoking article adopts the central heating method (FIG. 3B), a central heating element 32 is installed on the side wall of the smoking chamber. After the smoking article heats the fuming particles 1, the resulting mist is drawn by the filter section 34 of the smoking article.

Of course, the fuming particles 1 may be loaded and used in the electronic cigarette cartridge.

The fuming process of the fuming particles 1 is as follows. When suction proceeds, the amount of heat coming from the outside first causes melting or phase change in the coating layer 13 of the particles, which ruptures, and after the thermal energy enters the inner core layer 11, the gas inside the micropores is exceeded Condensation nuclei form and propagate through the mesopores to the macropore points on the surface. After the condensation nuclei come into contact with the smoker, the spice mixture, and the spice of the smoke layer 12 at the macropore point, they rapidly grow and penetrate the smoke layer 12 in a forceful way to form a mist, and finally It enters the oral cavity of the consumer through the filter section.

In contrast to the prior art, the present invention has the following advantageous effects.
