Related application

The present application claims priority to Chinese Patent Application Serial No. 2011-0112, the entire disclosure of which is hereby incorporated by reference.

Technical field

The present application relates to the field of heat atomization and, more particularly, to an aerosol-generating article and system.

Background technique

Aerosol-generating articles that are heated without burning have been widely used in the field of novel tobacco. Aerosol in the tobacco industry is the smoke produced by the heating of tobacco products. Such heated aerosol-generating articles generate an aerosol by transferring heat from a heat source to an aerosol-generating material. During pumping, the volatile compounds absorb heat and are released from the aerosol-generating material, entrained in the air and sucked by the user, reducing the known harmful smoke constituents produced by the burning and thermal degradation of tobacco in conventional cigarettes.

This type of new tobacco product that is heated and not burned is usually inserted into the inside of a cigarette similar to the shape of a conventional cigarette by using a long heater to heat the smoking substance, but since the smoking material is prepared using natural tobacco leaves. Ingredients and/or other fuming substances, during the heating process, a small amount of oily liquid substance including tar will overflow, and these liquid substances will remain on the cigarette accommodating chamber and the heater of the smoking article, if not cleared in time During the process of use, deposits will form, which may affect the heating performance of the heater and may crack the odorous substances, which will greatly affect the subsequent smoking taste.

A method and apparatus for cleaning a heating element of an aerosol generating device, comprising the steps of: contacting the heating element with an aerosol-forming substrate; The temperature is raised to a first temperature to sufficiently heat the aerosol-forming substrate to form an aerosol; eliminating contact of the heating element with the aerosol-forming substrate; and raising the temperature of the heating element to be higher than The second temperature at which the first temperature is high is such that the organic material adhered or deposited on the heating element is thermally released. This method has a good effect on substances with low boiling point or poor stability by high-temperature carbonization and pyrolysis of organic substances, but has no obvious effect on solid residues or residues that have been coked.

PCT Patent No. WO 2015165709 A1 to Philip Morris Production Company discloses a cleaning consumable for cleaning a heating element of an aerosol generating device, the cleaning consumable comprising a cleaning capable of releasing contact with a heating element when heated by the heating element The solvent of the solvent isolates the matrix. The cleaning solvent is capable of dissolving or partially dissolving one or more deposits or residues that may remain on the heating element after normal use, or chemically interacting with the deposit or residue. This method cleans the heating element by releasing the cleaning solvent from the solvent-separating matrix, which is a good complement to the aforementioned high-temperature cleaning method, but still does not solve the problem that the cigarette liquid material overflows and the smoking article needs to be cleaned.

Referring to FIG. 5, in an embodiment where the heating mode is built-in heating, the heater 24 is placed in the carrier tube 10 or as part of the carrier tube 10 when the aerosol-generating article 100 is manufactured, thereby forming the aerosol-generating substance 20 heating. In the present embodiment, the heater 22 is directly disposed in the aerosol-generating product 100, and the aerosol-generating substance 20 is coated, coated with the aerosol-generating substance 20, and placed in the aerosol-generating substance 20, And/or mixed with the aerosol generating material 20; the aerosol generating device 200 is provided with a power source 210, and when the aerosol generating article 100 is combined with the aerosol generating device 200, the heater 24 communicates with the power source 210 to generate heat.

In an embodiment, the aerosol generating device 200 is configured to receive the device conductive layer 220 or the conductive contact electrically connected to the positive and negative electrodes of the power source 210 through the wire 230 on the inner wall of the accommodating cavity of the aerosol-generating article 100. The sol-generating article 100 is disposed in an aerosol-generating device 200 that is in contact with the article conductive layer 22 to form an electrical connection to electrically connect the power source 210 to the heater 24. The device conductive layer 220 and the product conductive layer 22 may be two annular structures disposed at both ends of the aerosol generating material 20, respectively.

Referring to FIG. 6, in an embodiment, the anti-leakage layer 30 extends into the inner surface of the carrier tube to wrap at least a portion of the outer circumference of the aerosol-generating substance 20. For example, the leakage preventing layer 30 is disposed in the direction of the aerosol generating substance 20 in addition to the inlet end (the first end) of the carrier tube 10, and extends in a cylindrical shape in the aerosol generating substance 20 and The inner surface of the carrier tube 10 prevents the liquid substance generated by the heating from leaking to the tube wall of the carrier tube 10. Similarly, the anti-leakage layer 30 may only enclose a portion of the outer periphery of the aerosol-generating substance 20, particularly the outer periphery of the encapsulating aerosol-generating substance 20 near the inlet end, preventing the liquid substance generated by the heating from flowing out of the inlet end.

The aerosol-generating article adopting the above heating method has a structure similar to that of cigarettes, but liquid substance overflow occurs during heating, or gas generated during heating is condensed to form a small amount of oily liquid substance including tar, and then smoking articles are present. Problems that require frequent maintenance and cleaning.

Referring to FIG. 7, in the embodiment of the external heater plug-in heating, the elongated heater 240 of the aerosol generating device 200 is inserted into the carrier tube 10 from one end of the aerosol-generating article 100 to heat the aerosol-generating substance 20, An aerosol is generated for smoking. In order to facilitate the contact of the heater 240 with the aerosol generating substance 20 to improve heat transfer efficiency, the aerosol generating substance 20 is filled to a length of the carrier tube 10, and the heater 240 is inserted into the first end of the carrier tube 10 (intake end) The anti-leakage layer 30 is disposed such that the heater 240 passes through the anti-leakage layer 30 when inserted into the carrier tube 10, so that the gas or liquid substance generated by the aerosol-generating substance 20 due to heating is adsorbed or blocked inside the aerosol-generating product. Let it overflow.

In the embodiment where the heating mode is the wall heating, the outer surface of the carrier tube 10 has a region for abutting the heater, and contact heating is employed to facilitate rapid formation of the aerosol. Moreover, the contact area between the carrier tube 10 and the heater should be large, and the heat transferred into the carrier tube 10 is increased. The first end (intake end) of the carrier tube 10 is provided with an anti-leakage layer 30, so that the gas or liquid substance generated by the aerosol-generating substance 20 due to heating is adsorbed or blocked inside the aerosol-generating article from overflowing. . In an embodiment, an adsorption layer or a barrier layer, such as a liquid adsorption layer or a liquid barrier layer, is disposed on the inner surface of the carrier tube 10 such that the liquid substance generated by the aerosol-generating substance 20 due to heating is adsorbed or blocked in the aerosol-generating article. Do not let it overflow inside. The liquid barrier layer can be realized by a plurality of common materials such as a metal film or a polymer film impermeable to oily substances. Similarly, in order to prevent the gas substance from oozing out and condensing into an oily liquid substance such as tar in the smoking article, a gas adsorbing layer or a gas barrier layer may be provided. Of course, the adsorption layer can simultaneously have the functions of liquid adsorption and gas adsorption, and the barrier layer can simultaneously have the functions of liquid barrier and gas barrier.

Referring to FIG. 5 again, in an embodiment in which the heating mode is electric heating of the built-in heater, that is, when the heater 24 is disposed in the carrier tube 10 or as a part of the carrier tube 10, the heater 24 coats the aerosol generating substance. 20. The aerosol-generating material 20 is coated, placed in the aerosol-generating material 20, and/or mixed with the aerosol-generating material. For example, the heater 24 is a layer of a heat-generating film coated with an aerosol-generating substance 20, and the heat-generating film is heated to heat the aerosol-generating substance 20 to generate an aerosol. In addition, the carrier tube 10 is further provided with a conductive layer 22 or a conductive contact for connecting the electrodes of the power source 210, and may be disposed on the outer surface of the carrier tube 10 through which the heater 24 or the conductive contacts and the power source The electrodes of 210 are electrically connected. In the same manner as the aerosol-generating article of the tube wall heating mode, the first end (intake end) of the carrier tube 10 is provided with an anti-leakage layer 30, so that the gas or liquid substance generated by the aerosol-generating substance 20 due to heating is Adsorption or blocking does not allow it to escape inside the aerosol-generating article. In an embodiment, the liquid adsorbing layer or the liquid barrier layer is provided on the inner surface of the carrier tube 10, so that the liquid substance generated by the aerosol generating substance 20 due to heating is adsorbed or blocked inside the aerosol-generating article from overflowing. The liquid barrier layer can be realized by a plurality of common materials such as a metal film or a polymer film impermeable to oily substances. Similarly, in order to prevent the gas substance from oozing out and condensing into an oily liquid substance such as tar in the smoking article, a gas adsorbing layer or a gas barrier layer may be provided. Of course, the adsorption layer can simultaneously have the functions of liquid adsorption and gas adsorption, and the barrier layer can simultaneously have the functions of liquid barrier and gas barrier.

In fact, the liquid adsorption layer or the liquid barrier layer can be applied to a variety of different structures of aerosol-generating products and a variety of aerosol generation methods, that is, a variety of heating methods, but for different aerosol-generating products and aerosols. The mode of formation, the (best) constituent materials, structure, mode of operation and efficacy of the liquid adsorption layer or liquid barrier layer may vary. For example, the aerosol-generating article is plug-in heated by an external heater, and the heater is in direct contact with the anti-leakage layer 30 when heated or removed from the aerosol-generating article, requiring the anti-leakage layer 30 to withstand higher temperatures. When the temperature is higher than 200 ° C or even higher than 300 ° C, inorganic materials such as porous carbon, porous graphene sponge, glass fiber, or polyvinyl alcohol (PVA), polyacrylonitrile (PAN), polyphenylene sulfide ( PPS), chlorinated polyether, polyarylsulfone (PAR), polyetheretherketone (PEEK), polyparaphenylene (POB), polyimide (PI) and other high temperature resistant plastics as liquid adsorption layer, used The metal film or the film formed above is resistant to high temperatures as a liquid barrier layer. Since the temperature generated by the heating zone generally does not exceed 500 ° C, the anti-leakage layer 30 requires a heat-resistant temperature of less than 500 ° C. It is also possible to use the above materials to form an adsorption layer having both a liquid adsorption and a gas adsorption function, or a barrier layer having both a liquid barrier and a gas barrier. Similarly, the liquid adsorption layer and/or the gas adsorption layer is a molecular sieve, that is, a molecular sieve can be used as an adsorption layer having a function of liquid adsorption and/or gas adsorption, and the molecular sieve is a microscopic pore containing precise and single. Material that can be used to adsorb gases or liquids. The material constituting the molecular sieve is at least one of clay, porous glass, microporous charcoal, activated carbon, silica gel, and zeolite. As the gas adsorbing layer, it is also possible to trap a large volume of aerosol molecules by selective adsorption. If the aerosol-generating article is heated by induction heating or built-in heater, the heater may not be in direct contact with the leakage preventing layer 30, and the temperature to be tolerated is relatively low, and the temperature is lower than 100 ° C, in addition to the aforementioned resistance In addition to high temperature materials, low density polyethylene (LDPE), polyurethane (PU), ethylene vinyl acetate (EVA), nylon (PA), polyethylene (PE), polystyrene (PS), polychlorine can also be used. Made of ethylene (PVC), polyterephthalic acid (PET), polybutylene terephthalate (PBT), ABS resin, polymethyl methacrylate (PMMA), etc. The foam material or fiber is used as the liquid adsorption layer, and such a plastic film can also be used as the liquid barrier layer. In one embodiment, the anti-leakage layer 30 has a heat resistant temperature greater than 90 °C. It is also possible to use the above materials to form an adsorption layer having both a liquid adsorption and a gas adsorption function, or a barrier layer having both a liquid barrier and a gas barrier.

If the aerosol-generating article is heated by the tube wall, the temperature at which the anti-leakage layer 30 needs to withstand is between the above two conditions. When the temperature is higher than 100 ° C to 200 ° C, polypropylene (PP) may be used. Foamed material made of plastics with moderate heat resistance such as polyvinyl formal (PVF), polyvinylidene chloride (PVDC), polysulfone (PSF), polyphenylene oxide (PPO), and polycarbonate (PC) Alternatively, the fiber may be used as a liquid barrier layer, and such a plastic film may be used as a liquid barrier layer. It is also possible to use the above materials to form an adsorption layer having both a liquid adsorption and a gas adsorption function, or a barrier layer having both a liquid barrier and a gas barrier.
