Description

  The present description relates to a cleaning consumable for cleaning an aerosol generating device having a heating element, a method for cleaning the aerosol generating device, and an aerosol generating system comprising the aerosol generating device and the cleaning consumable.

  Aerosol-generating articles are known in the art in which the aerosol-forming substrate is heated rather than burned to produce an inhalable aerosol. One purpose of such heated aerosol generating articles is to reduce the known harmful smoke components produced by tobacco burning and pyrolysis in conventional cigarettes. In general, in such heated aerosol generating articles, the aerosol is generated by heat transfer to an aerosol-forming substrate or material that is physically remote from the heat source, which may be located in, around or downstream of the heat source. During smoking, volatile compounds are released from the aerosol-forming substrate by heat transfer from a heat source and are carried together into the air drawn through the smoking article. As the released compound cools, it condenses to form an aerosol that is inhaled by the consumer.

  WO2013036144 discloses an example of an aerosol generating device in which an aerosol forming substrate of an aerosol generating article that is in direct contact with a heating element is heated to form an inhalable aerosol. In such a device configuration, heat from the heating element can be transmitted almost instantaneously to at least a portion of the aerosol-forming substrate when the heating element is activated, and this can facilitate the rapid generation of aerosol. Furthermore, the overall heating energy required for aerosol generation is lower than in systems where the aerosol-forming substrate is not in direct contact with the heating element and heating of the substrate occurs by convection or radiation. sell. When the heating element is in direct contact with the aerosol-forming substrate, the initial heating of the portion of the substrate that is in contact with the heating element is accomplished by conduction.

  When an aerosol-forming substrate such as a tobacco substrate is heated, volatile compounds are released. Volatile compounds and aerosols released by heat from the heating element can become attached to the aerosol generator, particularly to the surface of the heating element. The particles of the aerosol-forming substrate itself can also adhere to the heating element, particularly when the heating element is in direct contact with the aerosol-forming substrate. For example, when using a device as described in WO20130102614, the tobacco substrate is warmed to a temperature above 200 ° C. by a heating blade, releasing volatile compounds, nicotine and glycerol, all of which are inhaled by the consumer. To form a respiratory aerosol. However, after smoking a plurality of aerosol generating articles, residues and dust tend to collect in the device, which means that regular cleaning of the device and heating blade is required.

  Particles and compounds adhered to and adhered to the heating element of the aerosol generator can prevent the heating element from functioning in an optimal manner. These particles and compounds can also be damaged when using the aerosol generator and can give the user an unpleasant or bitter flavor. For these reasons, it is desirable to periodically clean the heating element.

  Cleaning can be accomplished by a pyrolysis method in which the heating element is heated to a temperature high enough to burn any residue or deposits. However, pyrolysis is not always effective as it is. Instead of or in addition to pyrolysis, a brush or scraper may be used. However, physically cleaning the heating element of the aerosol generating device without damaging the heating element can be a delicate operation.

  As described herein, a cleaning consumable may be provided to clean the heating element of the aerosol generator. Cleaning consumables include a solvent-dispersing substrate that is capable of releasing a cleaning solvent when heated by a heating element. The cleaning solvent is released and comes into contact with the heating element. The cleaning consumable is dimensioned to engage the aerosol generator so that the heating element can dissipate the cleaning solvent by heating the solvent diffusion substrate. Thus, the cleaning consumable is preferably at least partly of substantially the same dimensions as the engageable portion of the aerosol generating article for generating an inhalable aerosol when heated by the aerosol generating device. . The solvent-dispersing substrate is configured to be penetrated by the heating element of the aerosol generator, and the solvent-dissipating substrate prevents the cleaning solvent from coming out until the cleaning consumable is engaged with the aerosol generator. Are sealed or sealed. In a preferred embodiment, the cleaning consumable is rod-like and similar to a cigarette.

  The solvent diffusion base is configured to be penetrated by the heating element of the aerosol generator. Thus, due to the penetrating action, the heating element approaches or comes into contact with the solvent-dispersing substrate before the heating step. Thereafter, the solvent that is diffused when the solvent-dispersing substrate is heated comes into contact with the heating element, so that unnecessary residues and deposits on the heating element can be dissolved or released.

  The cleaning solvent acts to at least partially dissolve or chemically change one or more residues or deposits left on the aerosol generating device by heating the aerosol generating article. The cleaning solvent may be a solvent that acts to at least partially dissolve or chemically change one or more residues or deposits left by heating the tobacco-containing substrate of the aerosol-generating article. preferable.

  The cleaning solvent is preferably sufficiently volatile to evaporate quickly after the cleaning consumable is removed from the aerosol generator. Thus, the solvent should not contaminate the aerosol generating device to the extent that the user can perceive an undesired taste or flavor upon consumption of the next aerosol generating article.

  The solvent-dispersing substrate is encapsulated or sealed to prevent cleaning solvent from exiting until the cleaning consumable engages the aerosol generator. For example, the solvent-dispersing substrate can be hermetically sealed in a polymer or foil wrapper so that the cleaning solvent is retained in the substrate. The wrapper can then be pierced upon engagement with the aerosol generator so that the cleaning solvent can exit the substrate. The aerosol generator heating element can be used to penetrate the wrapper enclosing the solvent-dispersing substrate, in which case the engagement with the aerosol generator is such that the heating element is simply inserted into the solvent-diffusing substrate. Can be done. The combination of the encapsulated or sealed substrate and the ability of the substrate to be penetrated by the heater allows the use of volatile cleaning solvents that evaporate if not encapsulated or sealed and deliver these solvents directly to the heater And cleaning can be achieved.

FIG. 2 is a schematic cross-sectional view of a first embodiment of the cleaning consumable of FIG. 1 engaged with an aerosol generator. FIG. 3 is a schematic cross-sectional view of a second embodiment of the cleaning consumable. FIG. 4 is a schematic cross-sectional view of a second embodiment of the cleaning consumable of FIG. 3 engaged with an aerosol generator.

  FIG. 1 illustrates a cleaning consumable 10 according to a first embodiment. The cleaning consumable 10 includes a solvent-dispersing substrate 20, a rigid support element 30, and a tip 40. These three elements are sequentially arranged in a coaxial arrangement and assembled by the cigarette paper 50 to form a rod. The rod has a proximal end 12 that terminates at a tip 40 and a distal end 13 located at the end of the rod opposite the proximal end. When assembled, the cleaning consumable 10 is 45 millimeters long and 7.2 millimeters in diameter.

  The solvent-dispersing substrate 20 has a length of 20 mm and is disposed toward the distal end 13 of the cleaning consumable 10. The solvent strip 20 includes a porous core material supplied from a substantially cylindrical porous polyethylene foam, such as Porex®. A longitudinally disposed cylindrical recess or hole 22 is defined in the foam. The pores in the foam hold the liquid component of the solvent-dispersing substrate that contains the ethyl acetate cleaning solvent. The liquid component also includes a fragrance component such as linalool.

  A foil seal 60 is disposed on the distal end 13 of the cleaning consumable 10 and serves to prevent the volatile elements of the solvent-dispersing substrate 20 from exiting.

  The rigid support element 30 is a hollow acetate tube having a length of 18 mm. This cleaning consumable element extends the length of the consumable and facilitates insertion and removal of the cleaning consumable from the aerosol generator.

  The tip is a polyethylene foam cylinder with a length of 7 millimeters. The tip 40 improves the appearance of the cleaning consumable.

  The elements specified above are assembled by tightly wrapping in the cigarette paper 50. The paper in this specific embodiment is a standard cigarette paper. The interface between the paper and each element positions the element and defines a rod of the cleaning consumable 10.

  FIG. 2 illustrates the cleaning consumable 10 when engaged with an aerosol generator. Aerosol generator 210 includes an outer cylinder 212 and a recess 213 for receiving an aerosol generating article (not shown) for consumption. The indentation can also receive a cleaning consumable 10. The heating element 290 is located in the recess 213 and is positioned to engage the distal end of the aerosol generating article and the distal end 13 of the cleaning consumable 10. The heating element 290 is formed of an insulating ceramic material such as alumina, and a metal track is disposed on the ceramic surface. The metal track is coupled to a power source and heated by means of resistance heating. The heating element is formed in the form of a blade.

  When used to consume an aerosol generating article, the aerosol generating article is pushed into the recess 213 such that the heating element 290 penetrates the aerosol-forming substrate of the aerosol generating article. Thereafter, the heating element is activated to heat the aerosol-forming substrate and generate an inhalable aerosol. Thus, the aerosol generating article is consumed. After consumption, the aerosol generating article is removed from the indentation 213. Residues originating from the aerosol-forming substrate may adhere to the surface of the heating element, and it is desirable to remove these residues regularly. To this end, the aerosol generating article can be engaged with the cleaning consumable 10 as shown in FIG.

  The cleaning consumable 10 engages the device 210 in the same manner that the aerosol generating article engages the device 210. The cleaning consumable 10 is inserted into the recess 213 of the apparatus 210 and applies a force to the cleaning consumable 10 so that the heating element 290 passes through the foil seal 60 and enters the recess 22. Once properly positioned, the heating element 290 is activated to heat the cleaning consumable well 22. The cleaning solvent held in the holes of the solvent diffusion substrate 20 volatilizes and interacts with the residue of the heating element. This interaction dissolves the residue and facilitates cleaning of the heating element.

  In addition to the generation of the cleaning solvent, fragrance is generated by evaporation of the fragrance component. This fragrance is dispersed in the environment.

  After a certain time has elapsed, the power supply to the heating element is turned off, and the cleaning consumables are removed from the aerosol-generating article. Any cleaning solvent or fragrance remaining on the heating element will rapidly evaporate and the aerosol generator can be used to consume additional aerosol generating articles.

  FIG. 3 illustrates an alternative embodiment of the cleaning consumable 310. The consumable is similar to the cleaning consumable described in connection with FIG. 1 and includes a solvent-dispersing substrate 320, a rigid support element 330, and a tip 340. These three elements are sequentially arranged in a coaxial arrangement and assembled by cigarette paper 350 to form a rod. The rod has a proximal end 312 that terminates at a tip 340 and a distal end 313 located at the end of the rod opposite the proximal end. When assembled, the cleaning consumable 310 is 45 millimeters long and 7.2 millimeters in diameter. The cleaning consumable 310 differs from that described in connection with FIG. 1 in that the solvent-dispersing substrate 320 does not have a dent.

  The solvent diffusion base 320 is formed of a porous polyethylene foam that can be penetrated by the heating element 290 of the aerosol generator 210. In use, the cleaning consumable 310 is inserted into the indentation 213 of the aerosol generator 210 as shown in FIG. Sufficient force is applied to the cleaning consumables to allow the solvent dissipation substrate 310 to be penetrated by the heating element 290. Once inserted, the heating element 290 is activated and heated. As the solvent-dispersing substrate is heated, the cleaning solvent held in the holes of the solvent-dispersing substrate volatilizes and interacts with the residue of the heating element.

  After a certain time has elapsed, the power supply to the heating element is turned off, and the cleaning consumables are removed from the aerosol-generating article. The physical interaction between the solvent stripping substrate 310 and the heating element 290 wipes the heating element when the cleaning consumable is removed. Thus, any deposits or residues partially dissolved by the cleaning solvent are wiped from the heating element when the cleaning consumable is removed.

  The above exemplary embodiments illustrate but do not limit the invention. In light of the exemplary embodiments discussed above, other embodiments consistent with the exemplary embodiments described above will now be apparent to those skilled in the art.
