Description

[Technical Field]

[0001] The present disclosure relates to a cleaning tool for an aerosol generating device, and more particularly to a cleaning tool for cleaning at least a heating chamber of an aerosol generating device. [Background technology]

[0002] Aerosol-generating articles in which an aerosol-forming substrate is heated rather than combusted to generate an inhalable aerosol are well known in the art. Typically, in such heated aerosol-generating articles, the aerosol is generated by the transfer of heat from a heat source to a physically separate aerosol-forming substrate or material. The aerosol-forming substrate may be located within, around, or downstream of the heat source. During use, volatile compounds are released from the aerosol-forming substrate by heat transfer from the heat source and are entrained in the air drawn through the aerosol-generating article. As the released compounds cool, they condense to form an aerosol.

[0003] International Patent Publication No. 2013 / 102614 discloses an example of an electrically operated aerosol generating device in which an aerosol-forming substrate of an aerosol-generating article is heated in direct contact with a heating element to form an inhalable aerosol. The heating element is in the form of a blade extending from the bottom chamber wall of the heating chamber. The heating element is inserted into an aerosol-forming substrate segment of the aerosol-generating article.

[0004] When an aerosol-forming substrate, such as a tobacco substrate, is heated, volatile compounds are released. The volatile compounds and aerosol generated by the heat from the heating element can be deposited on the aerosol-generating device, particularly on the bottom chamber wall of the heating chamber. This is particularly because residue on the side walls of the heating chamber can be at least partially removed by inserting and removing the aerosol-generating article. Particles from the aerosol-forming substrate itself can also become attached to the heating element, especially if the heating element is in direct contact with the aerosol-generating substrate. For example, when using the device described in International Patent Publication No. 2013 / 102614, the heating blade heats the tobacco substrate to a temperature of 200-350 degrees Celsius, releasing volatile compounds, nicotine, and glycerol that can form an aerosol. Nevertheless, residue and dust can collect inside the heating chamber of the device after multiple uses of the aerosol-generating article.

[0005] Residue and dust buildup on the bottom wall of the chamber can block the airflow passages of the aerosol generator. Additionally, the heating element is susceptible to damage if inappropriate tools or objects are used to clean the heating chamber. Summary of the Invention

[0006] According to one aspect of the present invention, a tool for cleaning an aerosol generating device having a heated chamber is provided. The tool may include a tool base. The tool may include first and second elongated members extending from the tool base. The first elongated member may have a first distal end distal to the tool base. The second elongated member may have a second distal end distal to the tool base. A slot may be defined between the first elongated member and the second elongated member. The tool may include a pivot member. The pivot member may be disposed between the base and both the first distal end of the first elongated member and the second distal end of the second elongated member. The pivot member may be configured to allow the first elongated member and the second elongated member to pivot. For example, the pivot member may allow the first elongated member and the second elongated member to pivot in a preferred direction transverse to the extension of the first elongated member. The pivoting member may be configured to restrict pivoting of the first and second elongate members in an unpreferred direction. The unpreferred direction may be any direction that is not a preferred direction. For example, the unpreferred direction may be any direction that includes an orthogonal component to the preferred direction.

[0007] Advantageously, the first and second elongate members may allow a tool to clean the heating chamber at the bottom wall near the base of the chamber. If the aerosol generating device has a heating element extending from the base of the heating chamber, the pivoting member may advantageously prevent movement of the first and second elongate members within the heating chamber that could damage the heating element.

[0008] According to another aspect of the present invention, a system is provided that includes an aerosol generating device that includes a heating chamber and a heating blade having a substantially rectangular cross-section that extends from a bottom chamber wall of the heating chamber into the heating chamber. The system also includes a tool for cleaning the aerosol generating device. The tool may include a tool base, a first elongated member extending from the tool base, and a second elongated member extending from the tool base. The first elongated member may have a first distal end distal to the tool base. The second elongated member may have a second distal end distal to the tool base. A slot may be defined between the first elongated member and the second elongated member. The first elongated member and the second elongated member may be configured to be received in the heating chamber such that the heating blade is at least partially received in the slot. The first elongate member and the second elongate member may be configured to be received within the heating chamber such that at least one of the first distal end of the first elongate member and the second distal end of the second elongate member extends to the bottom chamber wall, and reciprocating movement of at least one of the first distal end of the first elongate member and the second distal end of the second elongate member within the heating chamber may be configured to scrape the bottom chamber wall.

[0009] As used herein, the term "reciprocating motion," in the context of one or both of a first distal end of a first elongate member and a second distal end of a second elongate member within a heating chamber having a heating blade extending therein, refers to angular motion generally parallel to the plane in which the heating blade lies. The angular motion can be initiated by moving the tool base in a direction parallel to the heating blade and the slot. In response, the first elongate member and the second elongate member can move in a direction opposite to the movement of the tool base, causing one or both of the first distal end and the second distal end to scrape the chamber bottom wall.

[0010] Advantageously, a system including a cleaning tool provided with a first elongated member and a second elongated member defining a slot therebetween allows the tool to scrape or clean the bottom chamber wall of the aerosol generating device near the base of the heating element. Cleaning the heating chamber using the tool preferably does not damage the heating blade. The tool may also serve to clean the heating blade.

[0011] The tool base, the first elongated member, and the second elongated member may be integrally formed. The first elongated member and the second elongated member may be coupled to the tool base. The tool base, the first elongated member, and the second elongated member may be formed from any suitable material. For example, one or more of the tool base, the first elongated member, and the second elongated member may be formed from a metal material, a plastic material, or a combination of a metal material and a plastic material.

[0012] The tool base may include a handle that extends away from the first distal end of the first elongate member, for example, the handle may extend away from the first distal end of the first elongate member along the longitudinal axis of the tool.

[0013] One or both of the first and second distal ends may have a tapered shape. For example, one or both of the first and second distal ends may be narrower than a portion of one or both of the first and second distal ends closest to the tool base. The tapered shape may facilitate scraping the bottom wall of the chamber.

[0014] The tool may include a pivot member disposed between the base and both the first distal end of the first elongate member and the second distal end of the second elongate member. The pivot member may be configured to allow the first elongate member and the second elongate member to pivot in a preferred direction transverse to the extension of the first elongate member. The pivot member may be configured to restrict the first elongate member and the second elongate member from pivoting in an unpreferred direction. The unpreferred direction may include any direction that includes a component orthogonal to the preferred direction. When the tool is used to clean an apparatus having a heated blade extending into the heated chamber, the pivot member is preferably configured to prevent movement of the first elongate member and the second elongate member within the heated chamber, which could damage the heated blade.

[0015] The pivot member, or a portion of the pivot member, may define a periphery having one or more channels configured to receive ribs of the heating chamber when the pivot member is inserted into the heating chamber. When the ribs are received in the channels, axial rotation of the first and second elongate members within the heating chamber may be limited. The one or more channels may be flared at the receiving end. Providing the one or more channels with a flared receiving end may advantageously facilitate alignment of a tool and insertion of the tool into the heating chamber.

[0016] The pivoting member, or a portion of the pivoting member, may have an exterior shape and dimensions similar to the interior shape and dimensions of a heating chamber into which the pivoting member may be inserted. Such similar shapes and dimensions may facilitate insertion of the pivoting member into the heating chamber. Such similar shapes and dimensions may facilitate alignment of the pivoting member with the heating chamber. If the device includes a heating blade, proper alignment of the pivoting member with the heating chamber may result in proper alignment of the slot defined between the first elongated member and the second elongated member with the heating blade.

[0017] The pivoting member may comprise an elliptical member defining a periphery having at least one channel configured to receive a rib of the heating chamber. Engagement of the rib with the channel may prevent axial rotation of the first elongated member and the second elongated member within the heating chamber. The elliptical member may comprise a disk or a cylinder. The elliptical member may be elliptical in shape. The elliptical shape may include a circular shape. The at least one channel may be flared at the receiving end. Providing the at least one channel with a flared receiving end may advantageously facilitate alignment and insertion of a tool into the heating chamber.

[0018] The pivot member may be integrally formed with the tool base, the first elongated member, and the second elongated member. The pivot member may be rigidly coupled between the base and both the first distal end and the second distal end. The pivot member may be formed from any suitable material. For example, the pivot member may be formed from a metal material, a plastic material, or a combination of a metal material and a plastic material.

[0019] The tool may include bristles extending from the first elongated member, or the second elongated member, or both the first and second elongated members. The bristles may advantageously increase the effective cleaning area of the tool. The bristles are preferably stiff enough to clean the surface of the heated chamber, but not stiff enough to cause damage to the heated blade extending into the heated chamber. The bristles preferably contact the surface and detach from the surface of the heated chamber or heated blade when the tool is being used to clean the heated chamber.

[0020] Bristles may extend radially outward from one or both of the first elongate member and the second elongate member. The radially outward extending bristles may advantageously clean the inner circumferential surface of the heating chamber.

[0021] The bristles may be formed from any suitable material, for example, the bristles may be formed from metal filaments, or plastic filaments, or filaments comprising metal and plastic materials.

[0022] The first elongated member has a first flat surface facing the slot, and the second elongated member has a second flat surface facing the slot, the first flat surface extending through a first plane, the second flat surface extending through a second plane, the first plane and the second plane being parallel planes, and the first flat surface and the second flat surface extending parallel to each other. Providing a tool with first and second elongated members having such flat inner surfaces can prevent the first and second elongated members from damaging the heating element when the chamber bottom wall is scraped with the tool. Such an arrangement of flat inner surfaces of the first and second elongated members can be particularly useful in preventing damage when the tool is configured to prevent axial rotation when the chamber bottom wall is scraped. For example, axial rotation can be prevented by providing a channel along the periphery of the pivot element, the channel configured to receive a rib of the heating chamber.

[0023] At least one of the first elongate member and the second elongate member may include one or more ridges on a surface facing the slot. The one or more ridges may be configured to collapse at a threshold level of torque or bending. The one or more ridges may be formed of an elastically deformable material. The one or more ridges may advantageously clean the surface of the heater blade while the bottom chamber wall is being scraped or cleaned. Furthermore, the ridges configured to collapse or formed of an elastically deformable material may provide additional protection against damage to the heater blade.

[0024] The tool may include a cap. The cap may be configured to couple with the aerosol generation device. The tool may be configured such that one or both of the first elongated member and the second elongated member contact the bottom wall when the cap is coupled with the aerosol generation device. At least a portion of the cap may be configured to receive a portion of the aerosol generation device when the first elongated member and the second elongated member are received in a heating chamber of the aerosol generation device.

[0025] The cap may be made from any suitable material, for example, the cap may be made from a metal material, or a plastic material, or a combination of metal and plastic materials.

[0026] The tool may include a rod operatively connecting the first and second elongated members to the cap. The rod may enable reciprocating motion of the first and second elongated members. The rod may prevent axial rotation of the first and second elongated members. For example, the rod may operatively connect the first and second elongated members to the cap such that the first and second elongated members can pivot about the rod. Providing a cap and rod on the tool may advantageously provide controlled and consistent cleaning of the chamber bottom wall near the heating element. The cap and rod may also prevent axial rotation of the first and second elongated members, thereby preventing damage to the heating blade if the device includes a heating blade extending into the heating chamber. If the device includes a heating blade, the cap (or another element of the tool) preferably includes features configured to mate with corresponding features on the aerosol generation device to facilitate proper alignment of the first and second elongated members with the heating blade.

[0027] The rod may be made of any suitable material, for example, the rod may be made of a metal material, or a plastic material, or a metal and a plastic material.

[0028] The tool base may include a cleaning head for cleaning the aerosol generating device. The cleaning head may be positioned at an end of the tool opposite the first distal end of the first elongate member. When the cleaning head is inserted into the heating chamber toward the bottom wall, the distal end of the first elongate member extends away from the bottom wall. The cleaning head is preferably configured to clean areas of the bottom surface of the heating chamber that may be inaccessible to the first distal end of the first elongate member and the second distal end of the second elongate member. The cleaning head may include a scraping surface for cleaning the bottom surface of the heating chamber. A tool having a cleaning head facing the first distal end of the first elongate member and the second distal end of the second elongate member can advantageously be used to clean the heating chamber better than a tool without a cleaning head.

[0029] The first and second distal ends may be laterally movable relative to one another to adjust the width or shape of a slot formed between the first and second elongated members. The tool may include one or more bearings configured to engage at least one of the first and second elongated members to limit the width of the slot between the first and second distal ends. The one or more bearings may be configured to limit the width of the slot between the first and second distal ends to less than 3 millimeters, preferably less than 2 millimeters, and preferably less than 1.5 millimeters. The one or more bearings may be configured to limit the width of the slot between the first and second distal ends to a width between 0.2 millimeters and 1 millimeter wider than the thickness of the heated blade, preferably between 0.3 millimeters and 0.5 millimeters wider than the thickness of the heated blade. The tool may further include one or more resilient members positioned adjacent the first or second elongated members to provide lateral movement of the first and second elongated members. Each of the one or more resilient members may comprise a resilient ring. For example, each of the one or more resilient members may comprise an O-ring, for example a silicone O-ring.

[0030] The first and second elongated members are preferably laterally movable to adjust the width of the slot at the distal end of the tool during and after insertion of the tool into the heated chamber. For example, the first and second elongated members may be moved to increase the width of the slot at the distal end of the tool during insertion of the tool into the heated chamber, and may be moved to decrease the width of the slot at the distal end of the tool after insertion. Such lateral adjustment of the slot width may allow the first and second elongated members to be inserted into the heated chamber over the heated blade without damaging the blade during insertion. Thus, the tool easily conforms to the heated blade during insertion and can be moved into position to scrape or clean the bottom chamber wall near the heated blade after insertion. One or more bearings preferably limit lateral movement of the first and second elongated members beyond the point at which they can be inserted into the heated chamber.

[0031] The tool may include a motor coupled to the first elongated member and the second elongated member. The motor may be configured to provide reciprocating motion of the first elongated member and the second elongated member. The motor may be coupled to the tool base via a lever. A switch may be operably coupled to the motor to turn the motor on and off. The motor may be electrically powered. The motor may advantageously provide controlled and consistent cleaning of the chamber bottom wall.

[0032] The tool may include a cleaning station body configured to receive the aerosol generating device. The cleaning station body may be mechanically coupled to the first elongated member and the second elongated member to enable reciprocating motion of the first elongated member and the second elongated member. A lever may be mechanically coupled to the tool base to control the reciprocating motion of the first elongated member and the second elongated member. The lever may be manipulated to control the reciprocating motion of the first elongated member and the second elongated member. The cleaning station may advantageously provide controlled and consistent cleaning of the chamber bottom wall.

[0033] The tool may include three or more elongated members extending from the tool base. Additional slots may be defined between adjacent elongated members. One or more of the elongated members may be configured to bend or curve to allow a heating blade to pass through at least one of the additional slots. Providing three or more elongated members can increase the surface area that the tool can scrape or clean. Furthermore, if the aerosol generating device includes multiple heating elements, the additional slots can advantageously accommodate additional heating elements or blades.

[0034] The elongated members may include tapered sides. The tapered sides can advantageously allow the heating element to pass more easily between the elongated members, which provides additional protection against damage to the heating element during reciprocation. The distal ends of the elongated members may be tapered. The tapered distal ends can allow the heating element to pass more easily between the distal ends during insertion of the tool into the heating chamber, which provides additional protection against damage to the heating element.

[0035] The tool may include a freewheel attached to the tool base. The freewheel may rotate independently of the tool base and the elongated member. The freewheel may provide additional protection against axial rotation of the elongated member within the heating chamber. The freewheel may be connectable to the cleaning head. The freewheel may allow the cleaning head and the tool to rotate independently of each other when connected together.

[0036] The tool may include a consumable member. The consumable member may include a recess. The recess may be configured to receive an elongated member. The consumable member may have any suitable shape. For example, the consumable member may have a cylindrical, rectangular, or swab-like shape. The consumable member may be formed of any suitable material. For example, the consumable member may be formed of cotton material, foam material, or other material used for cleaning. The consumable member may advantageously increase the effective cleaning area of the tool.

[0037] The tool may include one or more protruding elements. A first protruding element may extend from the first elongated member and a second protruding element may extend from the second elongated member. The first protruding element and the second protruding element may be disposed 180 degrees apart from each other around the circumference of the tool. The first protruding element and the second protruding element may be disposed to protrude from the tool in a direction away from the slot.

[0038] The protruding elements may provide additional protection against movement of the first and second elongate members in undesired directions. The first and second protruding members may be resiliently deflectable. The first and second protruding members may exert an outward force when resiliently deflected by one or more walls of the heating chamber. The outward force may be sufficient to resist movement in the undesired direction. According to another aspect of the present invention, there is provided a kit comprising an aerosol generating device comprising a heating chamber and a heating blade having a substantially rectangular cross-section extending from a bottom chamber wall of the heating chamber into the heating chamber, and a tool as described herein.

[0039] According to another aspect of the present invention, there is provided a method including inserting a tool having elongated members defining a slot therebetween into a heating chamber of an aerosol generating device, the elongated members having a blade received in the slot and an end of the elongated member contacting a bottom chamber wall of the heating chamber, and also including scraping the bottom chamber wall with the end of the elongated member by moving the end of the elongated member using a reciprocating motion.

[0040] Preferably, scraping or cleaning the bottom chamber wall with the end of the elongated member can be accomplished without damaging the heater blade of the aerosol generating device. Damage to the heater blade can be prevented if a tool and device are configured to interact to prevent axial rotation of the first and second elongated members when the elongated members are received in the heating chamber. For example, axial rotation of the first and second elongated members can be prevented by providing a channel along the periphery of the pivot element, the channel configured to receive a rib on the heating chamber. As another example, axial rotation of the first and second elongated members can be prevented by providing a cap configured to align with the device and a rod that effectively connects the first and second elongated members to the cap.

[0041] The method may include widening the slot defined by the first and second elongated members before inserting the tool into the heated chamber, and narrowing the slot after inserting the tool into the heated chamber and before scraping the bottom chamber wall. Widening the slot during insertion allows the elongated members to be inserted over the heated blade without damaging the blade.

[0042] The method may include moving a lever of the cleaning station to move the end of the elongated member in a reciprocating manner. Advantageously, moving the lever of the cleaning station provides controlled and consistent cleaning of the bottom wall of the chamber near the heating element with the elongated member.

[0043] The method may include moving a tool around a rod connecting the cap to the elongated member to move the end of the elongated member using a reciprocating motion. Advantageously, moving the tool around the rod connecting the cap to the elongated member may provide controlled and consistent cleaning of the chamber bottom wall near the heating element.

[0044] The present invention is defined in the claims. However, the following provides a non-exhaustive list of non-limiting examples.

[0070] Figures 1-4 show a tool 110 for cleaning an aerosol generating device. Figure 1 shows a system 100 including an aerosol generating device 102 and a tool 110. Figure 2 shows the tool 110. Figure 3 shows a cross-sectional view of the system 100 with the tool 110 in position for cleaning the aerosol generating device 102. Figure 4 shows a cross-sectional view of the system 100 rotated 90 degrees from the view of Figure 3 with the tool 110 in position for cleaning the aerosol generating device 102.

[0071] The aerosol generating device 102 includes a heated chamber 104, a heating element 106, a chamber bottom wall 108, and ribs 134 (see FIG. 4). The heated chamber 104 defines a cavity within the aerosol generating device 102. The chamber bottom wall 108 is the interior surface of the heated chamber 104. The heating element 106 extends from the chamber bottom wall 108 into the heated chamber 104. As shown, the heating element 106 is a blade.

[0072] The tool 110 includes a tool base 118, a first elongate member 112-1, a second elongate member 112-2 (collectively referred to as the elongate members 112), and a pivot member 120. The elongate members 112 extend from the tool base 118. The first elongate member 112-1 includes a first distal end 114-1 distal to the tool base 118, and the second elongate member 112-2 includes a second distal end 114-2 (collectively referred to as the distal ends 114) distal to the tool base 118. A slot 116 is defined between the elongate members 112. The pivot member 120 is disposed between the tool base 118 and both distal ends 114. Pivoting member 120 includes channels 122 configured to receive and engage ribs 134 of heating chamber 104 to prevent axial rotation of elongated member 112 within the heating chamber.

[0073] Pivoting member 120 is configured to allow pivoting of elongated member 112 in a preferred direction transverse to the extension of the first elongated member. Pivoting member 120 is also configured to restrict pivoting of elongated member 112 in an unpreferred direction.

[0074] 3 and 4, the elongated member 112 is configured to be received within the heating chamber 104, such that the heating blade 106 is received within the slot 116. Additionally, the distal end 114 extends to the bottom chamber wall 108 such that reciprocating motion of the distal end within the heating chamber scrapes against the bottom chamber wall. In particular, the reciprocating motion can cause the distal end 114 to scrape against the bottom chamber wall adjacent the base of the heating blade 106.

[0075] The reciprocating motion is illustrated by dashed arrows 130-1, 130-2, 132-1, and 132-2. When tool base 118 is moved in the direction of dashed arrow 130-1, distal tip 114 is moved in the direction of dashed arrow 130-2. When tool base 118 is moved in the direction of dashed arrow 132-1, distal tip 114 is moved in the direction of dashed arrow 132-2. The reciprocating motion allows heating blade 106 to pass through slot 116 as chamber bottom wall 108 is scraped by distal tip 114. Pivoting member 120 is configured to limit movement of elongated member 112 and distal tip 114 in directions that include a component perpendicular to dashed arrows 130-1, 130-2, 132-1, and 132-2. These limitations on movement, including components perpendicular to the dashed arrows 130-1, 130-2, 132-1, 132-2, are configured to prevent the tool 110 from damaging the heater blade 106 during cleaning.

[0076] FIG. 5 shows a variation of the tool of FIGS. 1-4 in which the tool base 218 of the tool 200 includes a cleaning head 202 .

[0077] The tool 200 includes a tool base 218, a first elongate member 212-1, a second elongate member 212-2 (collectively referred to as the elongate members 212), and a pivot member 220. The elongate members 212 extend from the tool base 218. The first elongate member 212-1 includes a first distal end 214-1 distal to the tool base 218, and the second elongate member 212-2 includes a second distal end 214-2 (collectively referred to as the distal ends 214) distal to the tool base 218. A slot 216 is defined between the elongate members 212. The pivot member 220 is disposed between the tool base 218 and both distal ends 214.

[0078] Tool base 218 includes cleaning head 202. Cleaning head 202 extends away from distal end 214. Cleaning head 202 is configured to be inserted into a heating chamber of an aerosol generating device to clean areas of the bottom chamber wall of the heating chamber that may be inaccessible to distal end 214. Tool 200 is configured to fit within a case made up of two ends or caps 204-1 and 204-2.

[0079] FIG. 6 illustrates another variation of a tool according to embodiments described herein, in which the tool 300 includes a cap 302 .

[0080] The tool 310 includes a tool base 318, a first elongated member 312-1, a second elongated member 312-2 (collectively referred to as elongated members 312), a cap 302, and a rod 304. The elongated members 312 extend from the tool base 318. The first elongated member 312-1 includes a first distal end 314-1 distal to the tool base 318, and the second elongated member 312-2 includes a second distal end 314-2 (collectively referred to as distal ends 314) distal to the tool base 318. A slot 316 is defined between the elongated members 312. The rod 304 extends from the tool base 318 and connects the elongated member 312 to the cap 302. The rod 304 is rotatably connected to the cap 304, allowing the elongated member 312 to be moved in a reciprocating manner.

[0081] The reciprocating motion is illustrated by dashed arrows 330-1, 330-2, 332-1, and 332-2. When tool base 318 is moved in the direction of dashed arrow 330-1, distal tip 314 is moved in the direction of dashed arrow 330-2. When tool base 318 is moved in the direction of dashed arrow 332-1, distal tip 314 is moved in the direction of dashed arrow 332-2. The reciprocating motion allows heating element 306 to pass through slot 316 as chamber bottom wall 308 is scraped by distal tip 314. Rod 304 functions as a pivot point configured to permit movement of elongate member 312 and distal end 314 in the directions of dashed arrows 330-1, 330-2, 332-1, and 332-2, and to limit movement of elongate member 312 and distal end 314 in directions that include components perpendicular to dashed arrows 330-1, 330-2, 332-1, and 332-2. This limiting of movement that includes components perpendicular to dashed arrows 330-1, 330-2, 332-1, and 332-2 may prevent tool 310 from damaging heating element 306 during cleaning.

[0082] The cap 302 is configured to couple to an aerosol generating device. When the cap 302 is coupled to the aerosol generating device, the elongated member 312 may extend into a heating chamber of the aerosol generating device, with the distal end 314 configured to engage a bottom wall of the chamber of the aerosol generating device. The cap 302 is configured to align the slot 316 with the heating element when coupled to the aerosol generating device.

A slot 416 is defined between the elongated members 412. The lever 402 is mechanically coupled to the tool base 418 and controls the reciprocating motion of the tool 400. The lever 402 may be operated by a user to control the reciprocating motion of the tool 400.

[0085] The cleaning station body 404 is mechanically coupled to the elongated member 412. The mechanical coupling allows for reciprocating motion of the elongated member 412. The cleaning station body 404 is configured to receive an aerosol generating device. The cleaning station body 404 includes a receptacle 406. The receptacle 406 may be shaped to receive the aerosol generating device and to align a slot 416 with a heating element of the aerosol generating device.

[0100] The pivot member may include a plurality of channels 822. At least one of the channels 822 may be configured to engage a rib on the heating chamber to prevent axial rotation of the tool 800 within the heating chamber.

[0101] Figures 15-17 show one embodiment of a system 900 including a tool 910 with an adjustable slot 916. Figure 15 shows the system 900 prior to insertion of the tool 910 into the aerosol generation device 902. Figure 16 shows the system 900 with the tool 910 partially inserted into the aerosol generation device 902. Figure 17 shows the system 900 with the tool 910 fully inserted into the aerosol generation device 902.

[0102] The aerosol generating device 902 includes a heated chamber 904, a heating element 906, and a chamber bottom wall 908. The heated chamber 904 defines a cavity within the aerosol generating device 902. The chamber bottom wall 908 is the interior surface of the heated chamber 904. The heating element 906 extends from the chamber bottom wall 908 into the heated chamber 904.

[0103] The tool 910 includes a tool base 918, a first elongate member 912-1, a second elongate member 912-2 (collectively referred to as elongate members 912), a pivot member 920, a bearing 930, and a resilient member 932. The elongate members 912 extend from the tool base 918. The first elongate member 912-1 includes a first distal end 914-1 distal from the tool base 918, and the second elongate member 912-2 includes a second distal end 914-2 (collectively referred to as distal ends 914) distal from the tool base 918. A slot 916 is defined between the elongate members 912.

[0104] Pivot member 920 is disposed between tool base 918 and both distal ends 914. Pivot member 920 may include channels (not shown, see e.g., FIGS. 2 and 4) configured to engage ribs (not shown, see e.g., FIGS. 2 and 4) of heating chamber 904 to prevent axial rotation of elongated member 912 within the heating chamber. Pivot member 920 includes bearing windows 931 that allow bearings 930 to be engaged from outside of pivot member 920.

[0105] As shown, the tool base 918 can be pinched or manipulated to adjust the width of the slot between the distal ends 916. The bearings 930 are each configured to engage one of the elongate members 912 to limit the width of the slot between the distal ends 916. The bearings 930 are configured to engage with the sidewalls of the elongate members 912 and the pivot member 920 to limit the width of the slot between the distal ends 916. Prior to inserting the tool 910 into the heated chamber 904, the width of the slot between the distal ends 916 is limited so that the elongate members 912 can be inserted into the heated chamber 904. In other words, the bearings 930 limit the width of the slot between the distal ends 916 so that the distance between the outer edges of the distal ends 914 is less than the diameter of the heated chamber 904. When tool 910 is inserted into heated chamber 904, bearings 930 are configured such that at least a portion of each of bearings 930 extends through a respective bearing window 931 and thus engage with the interior wall of heated chamber 904. Such engagement further limits the width of the slot between distal ends 916, holding the distal ends in place to scrape bottom chamber wall 908 when tool 910 is fully inserted into heated chamber 904, as shown in FIG.

[0106] The resilient member 932 is positioned adjacent to the elongate member 912 and provides lateral resilience to the lateral movement of the first and second elongate members 912. The resilient member 932 may limit the width of the slot 916 when the tool base 918 is not being manipulated. The resilient member 932 may be a resilient ring.

A slot 1116 is defined between the elongate members 1112. The pivot member 1120 is disposed between the tool base 1118 and both distal ends 1114.

[0111] The tool base 1118 is coupled to a freewheel 1124. The freewheel 1124 rotates independently of the tool base 1118 and the elongated member 1112. The freewheel 1124 may prevent axial rotation of the elongated member 1112 within the heating chamber of the aerosol generating device. The freewheel 1124 may be configured to couple to the cleaning head 1102, as depicted in FIG. 22. The freewheel 1124 may allow the cleaning head 1102 and the tool 1100 to rotate independently of each other when coupled together.

[0112] The cleaning head 1102 includes a scraping surface 1104 and an embossed member 1106. The scraping surface 1104 may be configured to clean a surface of a heated chamber of an aerosol generating device. The embossed member 1106 may be coupled to a cap 1130.

[0113] The cap 1130 may be configured to couple to the cleaning head 1102. The cap 1130 may receive the tool 1100 within an interior volume 1132 when coupled to the cleaning head 1102.
