Description

Consumable for an aerosol-generating device
Technical Field
The present description relates to a cleaning consumable for cleaning an aerosol-generating device having a heating element, a method of cleaning an aerosol-generating device, and an aerosol-generating system comprising an aerosol-generating device and a cleaning consumable.
Background
Aerosol-generating articles in which an aerosol-forming substrate for generating an inhalable aerosol is heated rather than combusted are known in the art. The purpose of such heated aerosol-generating articles is to reduce known harmful smoke constituents produced by the combustion and thermal degradation of tobacco in conventional cigarettes. Typically in such heated aerosol-generating articles, the aerosol is generated by transferring heat from a heat source to a physically separate aerosol-forming substrate or material, which may be located within, around or downstream of the heat source. During smoking, volatile compounds are released from the aerosol-forming substrate by heat transfer from the heat source and become entrained in the air drawn through the smoking article. As the released compounds cool, they condense to form an aerosol which is inhaled by the consumer.
WO2013102614 discloses an example of an aerosol-generating device in which an aerosol-forming substrate of an aerosol-generating article is heated, the aerosol-generating device being in direct contact with a heating element to form an inhalable aerosol. In such a device configuration, heat from the heating element may be delivered almost immediately to at least a portion of the aerosol-forming substrate when the heating element is actuated, and this may facilitate rapid generation of an aerosol. Furthermore, the total heating energy required to generate the aerosol may be lower than in systems where the aerosol-forming substrate is not in direct contact with the heating element and heating of the initial substrate occurs primarily by convection or radiation. In the case where the heating element is in direct contact with the aerosol-forming substrate, initial heating of the portion of the substrate in direct contact with the heating element will be achieved by conduction.
When an aerosol-forming substrate (e.g. a tobacco substrate) is heated, volatile compounds are released. Furthermore, volatile compounds and aerosols generated by heat from the heating element may deposit on the aerosol-generating device, in particular on the heating element surface. The aerosol-forming substrate particles themselves may also adhere to the heating element, particularly where the heating element is in direct contact with the aerosol-forming substrate. For example, when using the device described in WO2013102614, the heating sheet heats the tobacco substrate to over 200 ℃, thereby releasing volatile compounds, nicotine and glycerin, all of which form an aerosol that can be inhaled by a co-smoker. However, after smoking a plurality of aerosol-generating articles, it is easy to collect residues and dust inside the device, which means that the device and the heating blade need to be cleaned regularly.
Particles and compounds adhering to and deposited on the heating element of the aerosol-generating device may prevent the heating element from operating in an optimal manner. These particles and compounds may also decompose during use of the aerosol-generating device and impart an unpleasant or bitter taste to the user. For these reasons, the heating element is cleaned as regularly as possible.
Cleaning may be accomplished by a pyrolysis process in which the heating element is heated to a temperature high enough to burn all residues or deposits. However, pyrolysis itself is not always effective. Brushes or scrapers may be used as an alternative or in addition to pyrolysis. However, physically cleaning the heating element of the aerosol-generating device without damaging the heating element may require a high degree of skill.
Disclosure of Invention
As described herein, a cleaning consumable for cleaning a heating element of an aerosol-generating device may be provided. The cleaning consumable includes a solvent-evolving substrate capable of releasing a cleaning solvent when heated by a heating element. The cleaning solvent is released and then contacted with the heating element. The cleaning consumable is dimensioned to engage with an aerosol-generating device such that the heating element can heat the solvent-evolving substrate to evolve the cleaning solvent. Accordingly, it is preferred that the cleaning consumable is dimensioned such that at least a portion is substantially identical to an engageable portion of an aerosol-generating article for generating an inhalable aerosol when heated by the aerosol-generating device. The solvent-evolving substrate is configured to be passable by a heating element of the aerosol-generating device, and the solvent-evolving substrate is wrapped or sealed to prevent egress of the cleaning solvent until the cleaning consumable is engaged with the aerosol-generating device. In a preferred embodiment, the cleaning consumable is in the form of a strip and shaped like a cigarette.
The solvent-evolving substrate is configured to be passed through by a heating element of the aerosol-generating device. Thus, the heating element may access or contact the solvent-evolving substrate by a traversing action prior to the heating step. The solvent segregates upon heating the solvent-segregation matrix, subsequently contacts the heating element, and may dissolve or loosen unwanted residues and deposits on the heating element.
The cleaning solvent at least partially dissolves or chemically alters one or more residues or deposits remaining on the aerosol-generating device by heating the aerosol-generating article. Preferably, the cleaning solvent at least partially dissolves or chemically alters the residual one or more residues or deposits by heating the tobacco-based substrate of the aerosol-generating article.
The cleaning solvent is preferably sufficiently volatile that it evaporates quickly after removal of the cleaning consumable from the aerosol-generating device. Thus, the solvent does not contaminate the aerosol-generating device, so that the user can detect an unwanted taste or fragrance during consumption of his next aerosol-generating article.
The solvent-evolving substrate is wrapped or sealed to prevent the release of cleaning solvent prior to the cleaning consumable being engaged with the aerosol-generating device. For example, the solvent-evolving substrate may be tightly sealed in a composite wrapper or foil wrapper so that the cleaning solvent may remain in the substrate. The wrapper may be pierceable when engaged with the aerosol-generating device to allow the cleaning solvent to be emitted from the substrate. The heating element of the aerosol-generating device may be used to pierce the packaging material surrounding the solvent-evolving substrate, in which case engagement with the aerosol-generating device to cause insertion of the heating element into the solvent-evolving substrate may simply be done. The wrapped or sealed substrate plus the ability of the substrate to be traversed by the heater enables the use of volatile cleaning solvents that would otherwise evaporate if not wrapped or densified, which also allows these solvents to be delivered directly to the heating device to accomplish cleaning.
As used herein, the term "aerosol-generating device" relates to a device that interacts with an aerosol-forming substrate to generate an aerosol. The aerosol-forming substrate may be part of an aerosol-generating article, for example a smoking article. An aerosol-generating device may comprise one or more components for supplying energy from a power source to an aerosol-forming substrate to produce an aerosol.
An aerosol-generating device may be described as a heated aerosol-generating device, which is an aerosol-generating device comprising a heating element. The heating element or heater is used to heat an aerosol-forming substrate of an aerosol-generating article to generate an aerosol, or to heat a solvent-evolving substrate of a cleaning consumable to form a cleaning solvent.
The aerosol-generating device may be an electrically heated aerosol-generating device, which is an aerosol-generating device comprising a heating element that operates with electrical power to heat an aerosol-forming substrate of an aerosol-generating article to generate an aerosol. The aerosol-generating device may be a gas heated aerosol-generating device. The aerosol-generating device may be a smoking device that interacts with an aerosol-forming substrate of an aerosol-generating article to generate an aerosol that is inhalable directly into a smoker's lungs through the smoker's mouth.
As used herein, the term "aerosol-forming substrate" relates to a substrate capable of releasing volatile compounds that can form an inhalable aerosol. Such volatile compounds may be released by heating the aerosol-forming substrate. The aerosol-forming substrate may be adsorbed, coated, impregnated or otherwise loaded onto a carrier or support. The aerosol-forming substrate may conveniently be part of an aerosol-generating article or a smoking article.
The aerosol-forming substrate may be a solid or a liquid, and may comprise nicotine. The aerosol-forming substrate may comprise tobacco, for example may comprise a tobacco-containing material containing volatile tobacco flavour compounds which are released from the aerosol-forming substrate when heated. In a preferred embodiment, the aerosol-forming substrate may comprise homogenised tobacco material, for example deciduous tobacco.
As used herein, the terms "aerosol-generating article" and "smoking article" refer to an aerosol-forming substrate capable of releasing volatile compounds that can form an aerosol. For example, the aerosol-generating article may be a smoking article that generates an aerosol that is directly inhalable into a user's lungs through the user's mouth. The smoking article may be disposable.
As used herein, an aerosol-generating article is a heated aerosol-generating article, which is an aerosol-generating article comprising an aerosol-forming substrate which is intended to be heated rather than combusted in order to release volatile compounds which can form an aerosol. The aerosol formed by heating the aerosol-forming substrate may contain less known harmful constituents than known harmful constituents produced by combustion or thermal degradation of the aerosol-forming substrate. The aerosol-generating article may be or may comprise a tobacco stem.
As used herein, the term "cleaning consumable" relates to a consumable that is insertable into an aerosol-generating device to enable or facilitate cleaning of the aerosol-generating article. The cleaning consumable includes a cleaning solvent that can be released or isolated from the cleaning consumable.
As used herein, the term "aerosol-forming substrate" relates to a substrate capable of releasing volatile compounds as cleaning solvents. Such volatile compounds may be released by heating the solvent-evolving substrate. The solvent-evolving substrate may be adsorbed, coated, impregnated or otherwise loaded onto a carrier or support.
The solvent-evolving substrate may be or may include a porous substrate material. The porous matrix material may be a foam, or may comprise coalesced fibers. The volatile cleaning solvent may be retained in the pores of the porous matrix material. For example, the solvent-evolving substrate may be a polymer foam impregnated with a cleaning solvent.
The solvent-evolving substrate may be provided with a slot or hole for receiving the heating element when the cleaning consumable is engaged with the aerosol-generating device. Thus, when heating the solvent-evolving substrate, the heating element may be nested within the solvent-evolving substrate. The solvent-evolving substrate may be penetrated by the heating element. For example, the solvent-evolving substrate may comprise a foam that can be penetrated by the heating element.
It may be particularly desirable for a portion of the cleaning consumable to be configured to contact the heating element during engagement or disengagement between the cleaning consumable and the aerosol-generating device. The cleaning consumable may, for example, be arranged or configured to wipe the heating element during removal of the cleaning consumable from the aerosol-generating device. Thus, deposits and residues that have been treated with cleaning solvents can be removed by physical interaction with the cleaning consumables. In a preferred embodiment, a portion of the solvent-evolving substrate interacts with the heating element so as to wipe the heating element during removal of the cleaning consumable from the aerosol-generating device.
The heating element may conveniently be shaped as a needle, pin, strip or sheet that can be inserted into the aerosol-generating article and clean the solvent-evolving substrate in the consumable. The aerosol-generating device may comprise more than one heating element, and reference to a heating element in this description means one or more heating elements.
In a preferred embodiment, the solvent-evolving substrate comprises one or more materials selected from the list consisting of polyethylene, polypropylene, polyethylene-polypropylene, polyethylene terephthalate, ethylene vinyl acetate, natural cellulose sponge or fiber, or glass entangled fiber.
In a preferred embodiment, the cleaning solvent comprises or is a solvent selected from the list consisting of 2-butoxyethanol, glycol ethers, mineral oil, ethyl acetate, isopropanol, ethanol, isoamyl acetate, isoamyl butyrate, and ethyl hexanoate.
In addition to the cleaning solvent, the cleaning consumable may include a fragrance that may segregate when the cleaning consumable is heated by the heating element. The flavourant may be released into the atmosphere, possibly serving to mask any unpleasant taste caused by residues after use of the aerosol-generating device. The fragrance provides an air freshening effect by emitting a pleasant smell and scent when the cleaning consumable is heated. Preferably, the fragrance is sufficiently volatile that it evaporates quickly after removal of the cleaning consumable from the aerosol-generating device. Thus, the flavourant must not contaminate the aerosol-generating device so that the user perceives an unwanted taste or flavour during consumption of the next aerosol-generating article.
In a preferred embodiment, the fragrance comprises one or more fragrance ingredients selected from the list consisting of amyl cinnamic aldehyde, amyl cinnamic alcohol, benzyl salicylate, cinnamic alcohol, cinnamic aldehyde, citral, coumarin, eugenol, geraniol, hydroxycitronellal, hydroxymethyl amyl cyclohexene carboxaldehyde, isoeugenol, methoxybenzyl alcohol, benzyl benzoate, benzyl cinnamate, citronellol, farnesol, hexyl cinnamic aldehyde 2-methyl-3- (4-tert-butylbenzyl) propanal, d-limonene, linalool, methyl heptyne carbonate, and 3-methyl-4- (2,6, 6-trimethyl-2-cyclohexen-1-yl) -buten-2-one.
The solvent evolving substrate may adsorb or otherwise retain the perfume. Alternatively, the perfume sequestering matrix separated from the solvent sequestering matrix may absorb or otherwise retain the perfume. Materials described hereinabove as suitable for use as part of a solvent-evolving substrate are also suitable for use in a fragrance evolving substrate.
The cleaning consumable may include a plurality of components, including a solvent-evolving substrate assembled to form a strip using packaging materials. The rod is preferably of similar size and shape to an aerosol-generating article designed for use with an aerosol-generating device. Thus, the cleaning consumable may have an outer diameter of between about 5mm and about 12mm, for example between about 6mm and about 8 mm. In a preferred embodiment, the cleaning consumable has an outer diameter of 7.2mm +/-10%.
The cleaning consumable may have a total length of between about 30mm to about 100 mm. In a preferred embodiment, the cleaning consumable has a total length of between about 40mm and 50mm, for example about 45 mm.
Preferably, the solvent-evolving substrate is in the form of a strip. Preferably, the solvent-evolving substrate is located at a distal end of the rod for insertion into a cavity of the aerosol-generating device. A heating element of the aerosol-generating device may pass through the distal end of the rod. For example, the distal end of the strip may be provided with a slot or hole through which the heating element may pass. The distal end of the strip may be sealed by a foil or membrane through which the heating element can pass.
In a preferred embodiment, the cleaning consumable is a strip comprising a cylindrical solvent evolving substrate, a rigid cylindrical membrane and a tip. The rigid cylindrical membrane is approximately the same diameter as the solvent-evolving substrate, between the solvent-evolving substrate and the tip. The function of the rigid cylindrical membrane is to provide rigidity for the cleaning supplies, enabling a user to clamp the cleaning supplies with the aerosol generating device. The rigid cylindrical membrane may be a hollow tube, such as a hollow acetate tube. The tip is for terminating the proximal end of the strip. For example, the tip may be a film or foil, or an insert such as a plastic insert.
The solvent-evolving substrate may have a length of between about 5mm and about 15mm, for example between about 8mm and about 12 mm. In one embodiment, the solvent-evolving substrate may have a length of about 10 mm. In a preferred embodiment, the solvent-evolving substrate may have a length of about 12 mm.

The wrapper may be a conventional cigarette paper. Advantageously, the components of the cleaning consumable may be assembled using existing cigarette assembly techniques.
A method of cleaning an aerosol-generating device comprising a heating element for heating an aerosol-generating article, which may comprise the steps of: engaging a cleaning consumable with the aerosol-generating device, the cleaning consumable comprising a solvent-evolving substrate, powering the heating element causing the solvent-evolving substrate to be heated and evolving a cleaning solvent. Preferably, the cleaning solvent is in contact with the heating element.
A heating element of the aerosol-generating device passes through the solvent-evolving substrate. Preferably, the method comprises removing the cleaning consumable from the aerosol-generating device, wherein the heating element is wiped by the cleaning consumable as it is removed from the aerosol-generating device. Thus, the cleaning solvent may loosen or partially dissolve any residue or deposit on the heating element, such as tobacco residue or deposit, which is then wiped off the heating element by interaction with the solvent-evolving substrate.
The aerosol-generating device may drive the heating element in accordance with more than one heating process. For example, there may be a first heating process for heating the aerosol-generating article to generate an inhalable aerosol, and a second heating process for heating the cleaning consumable. The maximum temperature of the heating process for heating the cleaning consumable may be lower than the heating process for heating the aerosol-generating article. For example, the cleaning consumable may be heated to a maximum temperature of less than 150 ℃, for example less than 120 ℃, or less than 100 ℃. In a preferred embodiment, the cleaning consumable may be heated to between 60 ℃ and 120 ℃.
The aerosol-generating device is capable of heating the heating element according to more than one heating process, and the user is able to select which heating process to use. For example, after the cleaning consumable has been inserted into the device, the user can press a button that actuates the heating element according to the cleaning process. Alternatively, the aerosol-generating device may automatically detect the presence of a cleaning consumable and automatically drive a corresponding cleaning process. Thus, the cleaning consumable may be marked with a label that is detectable by the aerosol-generating device, or that is slightly thicker or thinner than the aerosol-generating article, or that may include other means to enable the aerosol-generating device to detect the cleaning consumable.
An aerosol-generating system comprising an aerosol-generating device with a heating element and a cleaning consumable for engaging with the aerosol-generating device. Preferably, the cleaning consumable is a cleaning consumable as described above. The aerosol-generating system further comprises a plurality of aerosol-generating articles for generating an inhalable aerosol when heated by the aerosol-generating device.
The aerosol-generating articles may be packaged in a box or case containing a plurality of aerosol-generating articles and a cleaning consumable. Thus, the user may be prompted to clean the aerosol-generating article periodically before starting to consume the next cartridge or box of aerosol-generating article.

Detailed Description
Fig. 1 illustrates a cleaning consumable 10 according to a first embodiment. The cleaning consumable 10 includes a solvent-evolving substrate 20, a rigid support member 30 and a tip 40. These three elements are arranged sequentially and in coaxial alignment and are assembled by the cigarette paper 50 to form a strip. The strip has a proximal end 12 terminating in a tip 40 and a distal end 13 at an opposite end of the strip from the proximal end. When assembled, the cleaning consumable 10 was 45mm in length and 7.2mm in diameter.
The solvent-evolving substrate 20 has a length of 20mm and is placed towards the distal end 13 of the cleaning consumable 10. The solvent-evolving substrate 20 comprises a substantially cylindrical porous polyethylene foam, for example
Figure BDA0002129906820000081
A porous wick material is provided. The foam has longitudinally disposed cylindrical cavities or holes 22 disposed therein. The pores in the foam are capable of holding a solvent comprising ethyl acetate to segregate the liquid components in the matrix. The liquid component also includes a fragrance ingredient, such as linalool.
A foil seal 60 is disposed over the distal end 13 of the cleaning consumable 10 for preventing the emission of volatile components of the solvent-evolving substrate 20.
The rigid support element 30 is a hollow acetate tube 18mm in length. This element of the cleaning consumable extends the length of the consumable, facilitating insertion or removal of the cleaning consumable into or out of an aerosol-generating device.
The tip is a polyethylene foam cylinder with a length of 7 mm. The tip 40 may improve the appearance of the cleaning consumable.
The above-specified elements are assembled by being tightly wrapped in the cigarette paper 50. The paper in this particular embodiment is a standard cigarette paper. The interface between the paper and each component is used to locate the component and define the strip of the cleaning consumable 10.
Fig. 2 illustrates the cleaning consumable 10 engaged with an aerosol-generating device. The aerosol-generating device 210 comprises a sheath 212 and a cavity 213 for receiving an aerosol-generating article (not shown). The chamber may also receive a cleaning consumable 10. A heating element 290 is located within the cavity 213 in a position 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 made of an electrically insulating ceramic material, such as alumina, and metal traces are deposited on the ceramic surface. The metal track is connected with a power supply and is heated in a resistance heating mode. The heating element is shaped in sheet form.
When used to consume an aerosol-generating article, the aerosol-generating article is pushed into the cavity 213 such that the heating element 290 passes through the aerosol-forming substrate of the aerosol-generating article. The heating element is then actuated to heat the aerosol-forming substrate, generating an inhalable aerosol. Thereby, the aerosol-generating article is consumed. After consumption, the aerosol-generating article is withdrawn from the cavity 213. Residues produced by the aerosol-forming substrate may adhere to the surface of the heating element and it is desirable to remove these residues periodically. To this end, the aerosol-generating article may be engaged with a cleaning consumable 10, as shown in fig. 2.
The cleaning consumable 10 is engaged with the device 210 in the same manner as the aerosol-generating article and the decoration 210. The cleaning consumable 10 is inserted into the cavity 213 of the device 210 by applying a force to the cleaning consumable 10, and the heating element 290 passes through the foil seal 60 and into the cavity 22. Once properly positioned, the heating element 290 is actuated and heats the chamber 22 of the cleaning consumable the cleaning solvent held in the pores of the solvent-evolving substrate 20 volatilizes and interacts with the residue of the heating element. This interaction may dissolve the residue and facilitate cleaning of the heating element.
In addition to generating cleaning solvents, volatilization of perfume ingredients also produces a fragrance. The fragrance is emitted into the air.
After a period of time of powering the heating element, the power supply is turned off and the cleaning consumable is removed from the aerosol-generating article. Cleaning solvent or fragrance remaining in the heating element will evaporate rapidly and the aerosol-generating device can be used to consume other aerosol-generating articles.
FIG. 3 illustrates an alternative embodiment of a cleaning consumable 310. The consumable is similar to the cleaning consumable described in fig. 1, comprising a solvent-evolving substrate 320, a rigid support 330 and a tip 340. These three elements are arranged sequentially and in coaxial alignment and are assembled by cigarette paper 350 to form a strip. The strip has a proximal end 312 terminating in a tip 340, and a distal end 313 at an opposite end of the strip from the proximal end. When assembled, the cleaning consumable 310 is about 45mm in length and has an outer diameter of about 7.2 mm. The cleaning consumable 310 differs from the one described in fig. 1 in that the solvent-evolving substrate 320 has no cavity.
The solvent-evolving substrate 320 is made of porous polyethylene foam, which can be passed through by the heating element 290 of the aerosol-generating device 210. In use, the cleaning consumable 310 is inserted into the cavity 213 of the aerosol-generating device 210 as shown in figure 4, a force is applied to the cleaning consumable sufficient to cause the heating element 290 to pass through the solvent-evolving substrate 310. Once inserted, the heating element 290 is activated and heated. The solvent-evolving substrate is heated and the cleaning solvent retained in the pores of the solvent-evolving substrate volatilizes and interacts with residue on the heating element.
After a period of time of powering the heating element, the power supply is turned off and the cleaning consumable is removed from the aerosol-generating article. Physical contact between the solvent-evolving substrate 310 and the heating element 290 causes the heating element to be wiped when the cleaning consumable is removed. Thus, when the cleaning consumable is removed, any deposits or residues that may have been partially dissolved by the cleaning solvent are wiped off the heating element.
The exemplary embodiments described above are intended to illustrate rather than to limit the invention. In view of the above exemplary embodiments, those of ordinary skill in the art will now appreciate other embodiments consistent with the above exemplary embodiments.
