COMPLEX HEATING AEROSOL GENERATOR}

The present invention relates to an aerosol generating device, and to a composite heating aerosol generating device capable of heating a smoking article including a plurality of aerosol forming materials.

1 is a diagram illustrating an induction heating device for heating an aerosol-forming substrate according to the prior art. The induction heating device 1 comprises a device housing 10, which can be formed of plastic, and a DC power source comprising a rechargeable battery 11a.

The induction heating device 1 has a docking port 12 including a pin 12a for docking the induction heating device to a charging station or charging device for charging a rechargeable battery 11a. It contains more. The induction heating device 1 also comprises power supply electronics 13 configured to operate at a desired frequency, for example a frequency of 5 MHz as mentioned above. The power supply electronics 13 are electrically connected to the rechargeable battery 11a via suitable electrical connections 13a.

The tobacco-containing solid aerosol-forming substrate 20 comprising the susceptor 21 is received within the cavity 14 at the proximal end of the device housing 10 so that, during operation, the inductor L2 (a helically wound cylindrical an inductor coil) is inductively coupled to the susceptor 21 of the tobacco-containing solid aerosol forming substrate 20 of the smoking article 2. The filter part 22 of the smoking article 2 is arranged outside the cavity 14 of the induction heating device 1 so that, during operation, the consumer may inhale the aerosol through the filter part 22 .

The induction heating device includes an inductor arranged thermally adjacent to an aerosol-forming substrate, and the aerosol-forming substrate includes a susceptor. The alternating magnetic field of the inductor generates hysteresis loss and eddy currents in the susceptor, causing the susceptor to heat the aerosol-forming substrate to a temperature that releases volatile components that can form aerosols. do.

The induction heating device 1 described above does not disclose a configuration capable of heating a smoking article including a plurality of aerosol-forming substrates. In recent years, there has been an increasing demand for alternative methods that overcome the disadvantages of common cigarettes, for example, a method of generating aerosol by heating the aerosol-generating material in the cigarette rather than a method of generating aerosol by burning a cigarette. Demand is increasing.

In general, slurry leaf sheets, which are the main raw material of the tobacco medium, have weak tensile strength and are difficult to manufacture, and the tobacco medium contains a large amount of humectants, making its physical properties weak. In addition, tobacco media containing liquids such as glycerin are sensitive to humidity in the surrounding environment due to their hydrophilic nature, making it difficult to control the manufacturing process environment. There is a limit to the amount of liquid that can be contained in the tobacco medium.

In addition to the cigarette containing the tobacco medium, the liquid is stored in a separate cartomizer to generate additional aerosol, and when the user inhales the cigarette, the aerosol derived from the liquid is inhaled through the cigarette (so-called 'hybrid type'). However, there are difficulties in managing the liquid contained in the cartomizer (expiration date, deterioration, etc.), and condensation may occur in the airflow path through which the aerosol generated in the cartomizer moves, causing contamination.

Accordingly, there is a need to provide a liquid in a smoking article that is used once and then discarded and to obtain an aerosol from it. In order to include different aerosol-forming materials that can generate aerosol in one smoking article and inhale it, There is a need for a device that can generate aerosols using these smoking articles.

An aerosol-generating device of any size capable of heating a cavity provided in the device into which a smoking article can be inserted, and an interior or exterior of a first aerosol-forming substrate of a smoking article provided in the device to a first temperature range. A first heating means, a second heating means provided in the device, capable of heating the inside or outside of the second aerosol-forming substrate of the smoking article to a second temperature range, and a first heating means provided in the device, and a second heating means provided in the device. 2 A first sensor and a second sensor that respectively detect the temperature of the heating means, a rechargeable battery provided in the device and functioning as a direct current power source, and a rechargeable battery provided in the device and electrically connected to the first sensor, the second sensor and the battery, , and includes a control unit that receives direct current power supplied from a battery and controls the first heating means and the second heating means, respectively, according to the detection values of the first sensor and the second sensor.

Figure 2 conceptually shows a partial exploded perspective view and a cross-sectional view of a smoking article of a preferred embodiment that can be used in the composite heating aerosol generator of the present invention, and Figure 3 shows components of the smoking article according to Figure 2 and a wrapping surrounding the same. It conceptually shows the structure of the paper.

The smoking article that can be used in the composite heating aerosol generator of the present invention generates aerosol from the smoking article by heating the smoking article using an electric resistance method or an induction heating method rather than combustion, and the user inhales this aerosol. It is a form that does. These smoking articles contain within the smoking article an amount of aerosol-forming substrate and/or tobacco filler sufficient to produce a similar number of puffs as a conventional smoking article cigarette, and the aerosol is released in a predetermined amount. Once generated, it no longer produces significant amounts of aerosol and will be discarded by the user after one use.

The smoking article 50 that can be used in the composite heating aerosol generating device according to an embodiment of the present invention includes a tobacco body 58 containing a tobacco cut filler as a second aerosol forming material at the upstream end, and a first aerosol generator directly downstream thereof. It has a structure in which a liquid cartridge 56 containing a liquid composition as an aerosol forming material, a paper tube 54 providing an aerosol movement passage directly downstream thereof, and a filter 52 functioning as a mouthpiece are stacked, and these are wrapped. It is wrapped by paper 60. In the following description, the smoking article 50 having the above-described structure will be described, but depending on the embodiment, the relative positions of the liquid cartridge 56 made of the liquid composition and the tobacco body 58 made of the tobacco cut filler may be reversed. Additionally, instead of the tobacco body 58 as the second aerosol-forming substrate, another liquid cartridge 56 may be disposed as the second aerosol-forming substrate at the upstream end of the liquid cartridge 56, which is the first aerosol-forming substrate. Additionally, instead of the liquid cartridge 56, which is the first aerosol-forming substrate, another tobacco body 58 as the first aerosol-forming substrate may be disposed at the downstream end of the tobacco body 58, which is the second aerosol-forming substrate.

The liquid cartridge 56 includes a liquid or gel composition; A liquid or gel-like moisture absorbent wetted with a liquid or gel-like composition; It includes a wrapping paper that wraps the sides of the liquid or gel-like hygroscopic body into a cylindrical shape with a length of 7 to 20 mm and a diameter of 5 to 8 mm, and the liquid or gel-like hygroscopic body is a liquid or gel-like hygroscopic body in a liquid cartridge. It has a moisture absorption rate sufficient to absorb moisture and maintain 70 to 120 mg of the liquid composition in the liquid cartridge. The cylindrical shape with a length of 7 to 20 mm and a diameter of 5 to 8 mm meets the specifications of conventional cigarettes or heated smoking articles currently in use, and the liquid cartridge 56 having these specifications is inserted into the heated smoking article. If it is wrapped with a separate wrapping paper 60, from the user's point of view, there will be no difference from a regular cigarette or heated smoking article.

70 to 120 mg of the liquid or gel composition is absorbed into the liquid absorbent of the liquid cartridge 56 having these specifications, and this numerical range is the liquid amount when the user inhales the aerosol from the tobacco cut filler provided in one smoking article. It refers to the amount of liquid composition that can provide together with the aerosol derived from the composition. If the liquid or gel composition less than the above lower limit (70 mg) is absorbed into the liquid hygroscopic material, the aerosol derived from the liquid composition may be insufficient during the user's inhalation of the aerosol derived from the tobacco cut filler provided in the heated smoking article. Therefore, the liquid composition absorbed into the liquid cartridge must be above the lower limit (70 mg) or higher. When a liquid or gel-like composition exceeding the above upper limit (120 mg) is absorbed into a liquid hygroscopic material, it may be difficult for the liquid hygroscopic material in a liquid cartridge having the above specifications to maintain moisture absorption of the liquid composition, so the liquid composition Liquid may leak from the cartridge. Therefore, the liquid or gel composition absorbed into the liquid cartridge 56 must be below the upper limit value (120 mg). The preferred range is 80 to 110 mg, and the more preferred range is 90 to 105 mg.

The liquid moisture absorbent in the liquid cartridge 56 having the above specifications has a moisture absorption rate sufficient to maintain the liquid composition having the above range within the liquid cartridge. That is, the liquid composition remains absorbed by the liquid moisture absorber in the liquid cartridge and does not flow out of the liquid cartridge. Here, moisture absorption refers to the fact that the moisture absorbent is wetted by the liquid composition, but does not flow out. As described later, the filter-tube-liquid cartridge-cigarette body is wrapped with wrapping paper to form a smoking article, and the liquid cartridge is in direct contact with the tobacco body, tube, or filter without a separate member toward the upstream or downstream. The liquid composition absorbed by the liquid absorbent inside is simply absorbed and stored in the liquid absorbent and does not flow out toward the tobacco body, tube, or filter. For this purpose, the liquid composition is preferably absorbed into the liquid hygroscopic body in an amount of 0.13 to 0.32 mg/mm ³ per unit volume of the liquid hygroscopic body. The reason for this numerical limitation is similar to the reason for the numerical limitation for the amount of liquid composition absorbed by the liquid moisture absorbent of the present invention. In other words, if it is less than the above lower limit (0.13 mg/mm ³ ), the amount of liquid composition absorbed by the liquid hygroscopic material is not sufficient, so that the liquid composition is absorbed in the process of the user inhaling the aerosol derived from the tobacco cut filler provided in the heated smoking article. Since the aerosol derived from the liquid may be insufficient, the liquid composition absorbed into the liquid cartridge must be above the lower limit (0.13 mg/mm ³ ) or higher. If the liquid composition exceeding the above upper limit (0.32 mg/mm ³ ) is absorbed into the liquid hygroscopic material, it may be difficult for the liquid hygroscopic material in the liquid cartridge having the above specifications to maintain the liquid composition absorbing moisture, so the liquid composition This liquid may flow out of the cartridge.

The liquid composition comprises glycerin VG, optionally glycerin PG, water, and flavoring agents, wherein the liquid composition comprises, by weight, 70 to 100% glycerin VG, 0 to 20% glycerin PG, 0 to 10% of water, and additionally includes a flavoring agent added in an amount of 10% or less based on the total weight of the liquid composition thus obtained.

For example, flavoring agents include licorice, sucrose, fructose syrup, iso-sweeteners, cocoa, lavender, cinnamon, cardamom, celery, fenugreek, cascarilla, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, and lemon. Oils may include orange oil, mint oil, cinnamon, caraway, cognac, jasmine, chamomile, menthol, cinnamon, ylang ylang, sage, spearmint, ginger, coriander or coffee.

Alternatively, the wrapping paper can be manufactured from a metal thin film or metal foil, and as described above, it may be a paper-based wrapping paper with a metal thin film or thin metal plate added or laminated. According to a preferred embodiment of the present invention, the wrapping paper 61, which serves as a housing for the liquid cartridge 56, is composed of a combination of paper and aluminum foil, and the aluminum foil is in contact with the moisture absorber 56a so that the liquid composition is This prevents the liquid from flowing out of the side of the liquid cartridge 56 while being absorbed by the moisture absorbent.

The filter 52 on the downstream side of the liquid cartridge may have a hollow portion to form an airflow, but a filter without a hollow portion may be used. The filter may be composed of at least one segment and may include, for example, at least one of a tube filter, a cooling structure, and a recess filter. The tube filter has a shape containing a hollow interior. Tube filters and recess filters can be made of cellulose acetate, and the tubes that serve as cooling structures can be made of pure polylactic acid (PLA) or a combination of polylactic acid with other degradable polymers.

More specifically, the filter 52 can be made of materials such as acetate, paper, and PP, and the filter paper (wrapping paper) surrounding the filter can be made of plain paper, perforated paper, perforated paper, NWA (Non Wrapped Acetate), etc. can be classified. Additionally, the type of filter can be classified into a mono filter made of one segment, and a complex (double, triple, etc.) filter made of multiple segments. Filters may be made from acetate tow, plasticizer, activated carbon, X-DNA, and paper towels. Acetate tow refers to an aggregate of continuous filaments of cellulose acetate, and plays a critical role in determining the suction resistance, the most important characteristic of a filter. The properties of acetate tow are determined by denier.

Plasticizers make cellulose acetate fibers soft and pliable, forming bonds at contact points between the fibers and making the fiber bundles more rigid. Triacetin is used as a plasticizer for cigarette filters.

Activated carbon, one of the adsorbents, is a material whose main component is carbon, and can be classified according to particle size and properties. Raw materials used in activated carbon include vegetable raw materials such as wood, sawdust, and fruit peels (palm shell, bamboo, and peach seeds).

X-DNA refers to functional particles extracted from seaweed, concentrated, and processed. Compared to activated carbon, which is mainly used in cigarette filters, it does not affect the taste of cigarettes and is excellent at removing various carcinogens.

The function of wrapping paper is to maintain the shape of the filter plug during filter manufacturing. When manufacturing wrapping paper, physical properties such as porosity, tensile strength, elongation, thickness, and adhesive properties must be satisfied.

For example, the length of the liquid cartridge 56 may be 14.0 mm, the length of the filter 52 or the tube 54 may be 2.5 mm, and the length of the tobacco body 58 containing the tobacco cut filler may be 9.0 mm. Alternatively, as an example, the filter 52 may be 10 mm, the paper tube 54 may be 16 mm, the liquid cartridge 56 may be 10 mm, and the tobacco body 58 may be 12 mm.

The relative lengths of the filter 52, the paper tube 54, the liquid cartridge 56, and the tobacco body 58 and the relative arrangement of the liquid cartridge 56 and the tobacco body 58 are determined by the composite heating aerosol generator described later ( It may be related to the temperature of the aerosol in the process of the user inhaling the aerosol generated from the smoking article 50 by 100). Since the temperature of the aerosol generated from the liquid cartridge 56 and the temperature of the aerosol generated from the tobacco body 58 are different, and the longer the length of the paper tube 54 can further cool the high-temperature aerosol, the liquid Considering the temperature of the aerosol generated from the cartridge 56 and the tobacco body 58 and the relative arrangement of the liquid cartridge 56 and the tobacco body 58, the volume of the liquid cartridge 56 and the tobacco body 58 Their relative lengths and arrangements may vary in consideration of the dependent amounts of the liquid composition and tobacco cut filler and the heating method of the composite heating aerosol generator 100, which will be described later. It would not be difficult for those skilled in the art to satisfy the above conditions while manufacturing a smoking article of the same size as the smoking article currently on the market.

FIG. 4 is a conceptual diagram showing the process of manufacturing a hygroscopic rod to obtain the hygroscopic material shown in FIG. 3.

According to a preferred embodiment for manufacturing the liquid cartridge 56 shown in FIG. 3, the moisture absorbent formed in a cylindrical shape by the pipe structure 40 is applied to the liquid such as a spray device or needle before being introduced into the pipe structure 40. Passing through the composition injection part, the liquid composition is sufficiently sprayed or injected to provide the liquid composition into the moisture absorbent (56a), and the moisture absorbent (56a) passes through the pipe structure 40 and contains the liquid composition or is wet by the liquid composition. It becomes. Afterwards, the moisture absorbent into which the liquid composition has been absorbed is wrapped, for example, by wrapping paper made of paper (or paper laminated with aluminum foil) and cut to the required length (for example, 140 mm, 100 mm or 80 mm). A moisture absorbent rod 57 is formed. As described later, the absorbent rod 57 is cut into liquid cartridges 56 of a desired length (for example, 14 mm, 10 mm, 8 mm) and then combined with segments of other smoking articles (tubes, filters, tobacco bodies). They can be packed (wrapped) together to make an aerosol-generating smoking article 50.

FIG. 5 conceptually shows a cutting process for cutting a liquid cartridge from the absorbent rod shown in FIG. 4 to produce a liquid cartridge that can be included in a smoking article that can be used in the composite heating aerosol generating device of the present invention.

Figure 5 schematically shows the cutting process of cutting the moisture absorbent rod 57 obtained as above to manufacture the liquid cartridge 56, and as described above, it has a length of, for example, 140 mm, 100 mm or 80 mm. The moisture absorbent rod 57 flows into the groove of the index table 70 and moves to the conveyor belt 90 as the index table rotates. At this time, a rotating blade 80 is disposed on the path moving along the index table 70, and the moisture absorbent rod 57 is cut to a desired length, for example, 14 mm, 10 mm, or 80 mm, by 10 mm. It is cut into two liquid cartridges (56). Ten rotating blades (80) are arranged at equal intervals to cut a 140 mm moisture absorbent rod (57) into ten 14 mm liquid cartridges (56) or cut a 100 mm moisture absorbent rod (57) into ten 10 mm liquid cartridges. Alternatively, the 80 mm hygroscopic rod 57 can be cut into ten 8 mm liquid cartridges 56. As mentioned above, the above processes and equipment are used in the same way as those used when flavoring ingredients, etc. are included in filters in existing cigarette manufacturing, so there is no great difficulty in meeting mass production and quality control.

According to one preferred embodiment, a filter 52 functioning as a mouthpiece is located at the downstream end of the liquid cartridge 56, and a tobacco body 58 containing tobacco cut filler is located at the upstream end of the liquid cartridge 56. By packing each of these segments (filter, liquid cartridge, tobacco body) together, it is possible to manufacture an aerosol-generating smoking article 50. As described above, a tube 54 may be located between the filter 52 and the liquid cartridge 56, if necessary, to provide a passage for the aerosol to move and to cool the aerosol. Each of these segments, the filter 52, the tube 54, the liquid cartridge 56, and the tobacco body 58 are arranged side by side and packed together to obtain an aerosol-generating smoking article 50. In an actual manufacturing line, they can be lined up in sets of 10 or more and cut into multiple smoking articles after wrapping.

In any case, the liquid composition of the liquid cartridge 56 remains absorbed by the moisture absorbent 56a in the liquid cartridge and does not flow out of the liquid cartridge 61, during the process of manufacturing the smoking article or after completing the smoking article. Later, due to the high temperature or physical pressure applied to the liquid cartridge, the liquid dried material may flow out or vaporize into an aerosol and come out. First, according to a preferred embodiment of the present invention, the tobacco body is located upstream of the liquid cartridge, and the filter is located downstream of the liquid cartridge, so even if physical pressure is applied to the liquid cartridge from the outside, the liquid dried material passes through the filter or the tobacco body to the outside. The possibility of it leaking out is extremely low. Since the liquid composition begins to generate aerosol at about 120°C or higher, loss of the liquid composition during the manufacturing process can be prevented by wrapping the liquid cartridge 56 or controlling the manufacturing process at 100°C or lower. If a high temperature higher than the vaporization start temperature of the liquid composition is inevitably required during the manufacturing process, the amount of liquid composition lost during the process can be estimated, added to the required amount, and the amount expected to be lost can be added to manage the liquid composition by additionally absorbing moisture. there is.

Hereinafter, embodiments of a composite heating aerosol generator 100 for generating aerosol from a smoking article that can be used in the present invention will be described.

It is an aerosol generating device. The heating means may be provided by a resistance heating method or an induction heating method as will be described later. For example, the smoking article (50) is heated to a temperature of 100 - 400 ° C and inserted into the cavity of the composite heating aerosol generating device (100). An aerosol is generated by heating the aerosol forming material provided inside. According to a preferred example, the target temperature may be in the range of 200 to 350 ℃, and according to a more preferred example, the target temperature may be in the range of 250 to 320 ℃ (for example, 280 ℃ may be set as the target) (maybe). In some cases, the target temperature may be in the range of 150 to 250 ℃ (for example, 180 ℃ may be set as the target temperature), and this depends on whether the object to generate aerosol is a liquid composition (glycerin, etc.) or a cigarette lighter. Alternatively, it may vary depending on whether the liquid composition, such as glycerin, has been absorbed from the tobacco. In any case, the aerosol generated within the smoking article 50 is inhaled into the user's mouth through the tube 54 and the filter 52, so even considering cooling during the inhalation process, if the temperature of the generated aerosol is excessively high, the user There is a risk of discomfort or burns to the user, and excessive aerosol may be generated, making multiple puffs difficult. Taking this into account, the target temperature of the heating element must be determined in advance. Additionally, for the above reasons, the upper limit of the target temperature of the heating element is limited as above.

According to a preferred embodiment, the temperature at which the generated aerosol passes through the tube 54 and the filter 52 can be measured as the mouth end temperature. In order to avoid causing discomfort to the user, the temperature of the aerosol is 50°C. The temperature should be below, preferably below 45°C. The mouth end temperature of a preferred aerosol is in the temperature range of 25 to 45° C., and the more preferred mouth end temperature of the aerosol is in the temperature range of 30 to 40° C.
