Background technique

The traditional electronic cigarette is mainly composed of an atomizer, a battery part and a cigarette holder. The battery unit provides power to heat the heating wire of the atomizer. The heating wire is generally wound with an oil suction rope. The two ends of the oil suction rope are placed in the oil-liquid container. High, the smoke on the oil sucking rope is heated and volatilized to form smoke, which is sucked into the mouth of the smoker from the mouthpiece. Because it has not been burned, the content of harmful substances such as carbon monoxide and tar is small, which greatly reduces the harm of second-hand smoke.

Low-temperature heating smoke is also called heating non-combustion smoke, which is more common in the form of cigarettes. However, unlike traditional cigarettes that generate smoke, low-temperature heating smoke designed with the concept of "heating without burning" can make the tobacco just heat up to Enough to give off flavor without igniting tobacco leaves. Under normal circumstances, ordinary cigarettes will produce many harmful substances under the high temperature of 350 ℃ to 1000 ℃, and most of the low-temperature heating cigarettes work below 300 ℃, which greatly reduces the harmful substances in first-hand and second-hand smoke.

In order to reduce the temperature of the smoke at the filter, the traditional solution is to set a cooling section in the tobacco branch, separating the smoke section from the filter, so that the smoke generated from the smoke section is cooled in the cooling section, and then Flow out through the filter. The preparation process of such cigarettes is separately prepared in the tobacco material section, the filter tip and the cooling section, and the multi-segment composite process is used to wrap each section into a complete cigarette. These processes are often difficult to achieve in traditional cigarette machines or the cost is high.

1 and FIG. 2, an embodiment of the present invention provides an aerosol-generating product 100 and an aerosol-generating system 10 having the aerosol-generating product 100. The aerosol generating system 10 further includes an aerosol generating device 200 for passing an electric current into the energized heating element 120.

The aerosol-generating article 100 includes a smoke material and an energized heating element 120. The tobacco material is used to generate an aerosol, and includes a first tobacco material section 112 and a second tobacco material section 114, and the first tobacco material section 112 is disposed upstream of the second tobacco material section 114. The energized heating element 120 is disposed on the first smoke material segment 112, and the second smoke material segment 114 is far from the energized heating element 120 relative to the first smoke material segment 112. The second smoke material section 114 is used to cool the aerosol generated by heating the first smoke material section 112.

In an embodiment, the position of the energized heating element 120 may be used to divide the tobacco material into a first tobacco material segment 112 and a second tobacco material segment 114 in the length direction of the aerosol-generating product 100. Specifically, the energized heating element 120 is disposed at a relatively upstream position in the tobacco material, so that the tobacco material that is upstream is defined as the first tobacco material section 112, and the tobacco material that is downstream without the energized heating element 120 is defined as the second烟 料 段 114。 Smoke material section 114. The energized heating element 120 is configured to heat the first tobacco material section 112, preferably the first tobacco material section 112 is heated to 150 ° C to 500 ° C, and more preferably 200 ° C to 400 ° C. The temperature of the aerosol generated after the first tobacco material section 112 is heated is high. The high-temperature aerosol enters the downstream second tobacco material section 114 and indirectly heats the second tobacco material section 114, so that the second tobacco material section 114 can be heated. Heating generates aerosols while cooling the aerosols generated in the first smoke section 112. During the manufacturing process of the aerosol-generating product 100, the energized heating element 120 is combined with the tobacco material. By controlling the setting position of the energized heating element 120, two smoke material segments can be determined, and there is no need to provide separate support for the material. The hollow tube avoids the complicated connection process, and can easily prepare the aerosol-generating product 100 with a cooling effect.

The second smoke material section 144 can cool the aerosol generated by the first smoke material section 112 in various ways. In an embodiment, when the second tobacco material segment 114 has a larger size (for example, a longer length), the high-temperature aerosol generated by the first tobacco material segment 112 is in the second tobacco material segment 114. During the middle flow process, heat exchange with the second smoke section 114 can be sufficiently formed to reduce the temperature. For example, when the diameters are the same, the dimensional ratio of the first and second smoke sections 112 and 114 in the length direction is preferably 2: 1 to 1:10. In another embodiment, the second tobacco material section 114 has more volatile substances, and the volatile substances are used to sufficiently absorb the heat of the high-temperature aerosol to reduce the temperature of the high-temperature aerosol. . Preferably, the content ratio of the substance whose volatilization temperature is lower than 170 ° C. in the second tobacco section 114 is higher than the first tobacco section 112. In the above two embodiments, the temperature of the airflow that finally flows out of the aerosol-generating product 100 can be reduced to a proper temperature by setting the second smoke material section 114, and the periphery of the second smoke material section 114 can be provided with airtightness. Or a poorly permeable support tube.

In a preferred embodiment, the aerosol-generating article 100 further includes a cigarette paper 150.

The cigarette paper 150 is breathable, and gas can enter the second smoke material section 114 from the side through the cigarette paper 150. The cigarette paper 150 on the periphery of the second tobacco material section 114 is used for ventilation, so that the unheated air directly enters the second tobacco material section 114, and is mixed with the high-temperature aerosol entering from the first tobacco material section 112. , Reduce the temperature of the downstream airflow. The cigarette paper 150 is flexible and easily deforms after being compressed. The second tobacco material section 114 not only plays the role of generating aerosol, but also supports the cigarette paper 150 by itself, and separates a section of gas mixing area to make the mixed paper The gas cools.

In a preferred embodiment, the user includes at least three parts in the airflow inhaled downstream of the aerosol-generating article 100, (1) heating the aerosol generated by the first aerosol section 112 by an energized heating element 120; (2) by The aerosol generated by the second aerosol section 114 heated by the heat of the aerosol produced by the first aerosol section 112; (3) the air directly entering from the side through the cigarette paper 150 surrounding the second aerosol section 112. These gases are mixed with each other in the second smoke section 114 and downstream of the second smoke section 114 to reach a relatively low temperature, which is suitable for users to suck. Preferably, the gas entering the second smoke section 114 from the side, that is, the above-mentioned part (3), accounts for 5% to 70% of the total amount of gas flowing through the second smoke section 114, More preferably, it is 40% to 60%. In an embodiment, the ratio of the lengths of the first smoke material section 112 and the second smoke material section 114 is 4: 1 to 3: 7, which provides an appropriate amount of low-temperature air for the aerosol-generating article 100, which avoids The temperature of the air flow from the downstream is too high, and to avoid excessive condensation of volatile substances downstream.

The material of the cigarette paper 150 may be a highly air-permeable material, for example, a cigarette paper having microporosity, preferably an existing conventional cigarette or a low-temperature heating cigarette. The cigarette paper has a suitable weight and flexibility. Performance, air permeability (such as 30-110CU) and burning speed, and has a high longitudinal tensile strength. In order to increase the amount of air intake from the cigarette paper 150 to the second tobacco material section 114, in one embodiment, the surface of the cigarette paper 150 wrapped around the periphery of the second tobacco material section 144 is provided with ventilation holes. .

In one embodiment, the aerosol-generating product 100 further includes a filter 130 disposed at the most downstream of the aerosol-generating product 100. A low-temperature airflow flows out of the filter 130 for suction by a user. The second smoke material section 114 is disposed between the first smoke material section 112 and the filter 130, and separates the first smoke material section 112 from the filter 130.

In the embodiment of the present invention, the electric heating element 120 is disposed inside the aerosol-generating product 100, that is, the electric heating element 120 is an element of the aerosol-generating product 100, which can be used in the manufacturing process of the aerosol-generating product 100. The smoke 110 and the electrified heating element 120 are brought into better and sufficient contact to improve heating efficiency. Since the energized heating element 120 is added in the process of manufacturing the aerosol-generating article 100, the shape and structure of the energized heating element 120 can be diversified, and it does not need to have high strength to withstand multiple insertions of the tobacco material 110. pressure. The aerosol-generating product 100 can be a disposable product, so the energized heating element 120 can also be disposable, which avoids problems caused by repeated use of the energized heating unit, such as tar remaining on the surface of the energized heating element 120. Pollution caused by the difficult removal of substances and accumulation or retention of harmful substances in the aerosol generating device 200. In one embodiment, the aerosol-generating article 100 is a disposable cigarette. It can be understood that it is precisely because the energized heating element 120 and the tobacco are directly combined in the aerosol-generating product 100 that when the tobacco is heated, compared with the traditional low-temperature heating smoke, the temperature rises faster, in order to avoid the discomfort caused by the high inlet temperature It is indeed necessary to cool the aerosol generated by the first smoke section 112.

The first tobacco material section 112 and the second tobacco material section 114 may be made of the same tobacco material, and the first tobacco material section 112 and the second tobacco material section 114 are defined only by the position of the energized heating element 120.

Preferably, the second tobacco material segment 114 may include more substances with lower volatilization temperature than the first tobacco material segment 112, so that the second tobacco material segment 114 can generate more aerosols at a lower temperature. . In one embodiment, the proportion of substances with a volatilization temperature in the second tobacco material section 114 between 80 ° C and 250 ° C is higher than that of the first tobacco material section 112. The volatilization temperature of ordinary tobacco material may be relatively high. In order for the second tobacco material section 114 to better realize the cooling function, preferably, the second tobacco material section 114 may further include a low-temperature fogging agent such as propylene glycol and glycerin. At least one of alcohols in which the propylene glycol has a lower fogging temperature. The first tobacco material section 114 may or may not include a low-temperature fogging agent, as long as the content of the low-temperature fogging agent in the second tobacco material section 114 is greater than the low-temperature fogging agent in the first tobacco material section 112. Therefore, under the condition that the second smoke material section 114 is not directly heated, a part of aerosol is also generated under the action of the hot air flow, so as to compensate for the attenuation of the smoke amount caused by the cooling effect of the second smoke material section 114. At the same time, using the heat of the hot air stream to heat the second smoke section 114 to generate aerosol can more fully utilize the thermal energy, improve the heat utilization rate, and reduce the battery load.

Preferably, the second tobacco material section 114 further includes an aromatic substance, and the aromatic substance mainly includes at least one of aroma components of aromatic plants or artificial products.

For example, in one embodiment, the aerosol-generating article 100 may further include a hollow tube 160 disposed at an end of the second smoke material section 114 opposite to the filter 130. Between departments. In another embodiment, the hollow tube 160 extends to the periphery of the filter 130 and surrounds the filter 130. In another embodiment, the cigarette paper 150 extends to the periphery of the filter 130, and the cigarette paper 150 between the second tobacco material section 114 and the filter 130 surrounds a hollow section. Alternatively, the space may be filled with a porous material.

Preferably, the aerosol-generating product 100 is provided with vent holes on the outer surface corresponding to the interval, so that more unheated air can directly enter the aerosol-generating product 100 without passing through the first smoke section 112. For example, in the embodiment having the hollow tube 160, a wall of the hollow tube 160 may be provided with a vent hole. In the embodiment in which the hollow section is wrapped directly by the cigarette paper 150, the cigarette paper 150 corresponding to the hollow section may be provided with a through hole.

In the aerosol-generating product 100, the energized heating element 120 only needs to be capable of converting electrical energy into thermal energy, and heating the first tobacco material section 112. The energized heating element 120 may cover the first tobacco section 112, be covered by the first tobacco section 112, and / or be placed in the first tobacco section 112.

For example, the current heating layer is at least one of metal foil, alloy foil, carbon paper, carbon fiber paper, polyimide heating film, self-supporting graphene film, and self-supporting carbon nanotube film. In this embodiment, the self-supporting electric heating layer can replace the cigarette paper, and plays the role of integrally wrapping, supporting, and containing the tobacco in the first tobacco section 112. The flexible electrified heating layer capable of bending and winding can be easily combined with the traditional cigarette manufacturing process, instead of or wrapped with the cigarette paper through the cigarette machine outside the first tobacco material section 112, and wrapped in the first cigarette material section 112. The overlap of the cigarette paper 150 on the periphery of the second tobacco material section 114, for example, by the traditional cigarette making connection, simplifies the process and reduces the manufacturing cost compared with the method of setting a hollow tube in the cigarette.
