Description

Technical Field

[0001] The present disclosure relates to an aerosol generating system and a cartridge for an aerosol generating system.

Background Art

[0002] In many known aerosol generating systems, an aerosol-forming substrate is heated and vaporized to form a vapor. The vapor is cooled to form an aerosol. In some aerosol generating systems, such as an electrically heated smoking system, this aerosol is then inhaled by a user. An aerosol generating system often comprises two parts, namely a cartridge and a control body. The control body includes electronics for controlling the aerosol generating system. A cartridge for an aerosol generating system typically comprises an aerosol-forming substrate and a heater for heating the aerosol-forming substrate. This type of cartridge may include electrical contacts for electrically connecting the heater to the control body. The aerosol-forming substrate is typically a liquid.

Summary of the Invention

Problems to be Solved by the Invention

[0003] Some conventional cartridges have one or more removable or fragile barriers to prevent leakage of the liquid aerosol-forming substrate before use. The barriers can be removed or destroyed when the user is ready to use the cartridge. However, such configurations have several drawbacks. For example, the barriers may be accidentally removed or destroyed during transport. It may not be possible to reseal the cartridge after such barriers have been removed or destroyed. This may lead to leakage of the liquid aerosol-forming substrate before the first use or between uses of a multi-use cartridge. Liquid leakage can interfere with the electrical components of the system, cause inconvenience to the consumer, or both. Furthermore, such configurations may be difficult for consumers to handle, or difficult to manufacture, or both.

[0004] It is desirable to address these issues or at least provide a viable alternative. [Brief explanation of the drawing]

[Figure 9] This shows a schematic cross-sectional view of the aerosol generation system according to the third embodiment of the present invention. [Modes for carrying out the invention]

[0006] According to an aspect of the present invention, a cartridge for an aerosol generating system is provided. The cartridge may comprise a first component comprising a storage section for holding an aerosol-forming substrate and an aerosol-forming substrate outlet. The cartridge may comprise a second component comprising an aerosol-forming substrate inlet and an aerosol-generating element. The cartridge may further comprise a sliding mechanism that connects the first component to the second component and is configured to allow the first component to translate from a first position to a second position relative to the second component. In the first position, the aerosol-forming substrate outlet and the aerosol-forming substrate inlet may not be aligned with each other, so the aerosol-forming substrate cannot pass from the first component to the second component. In the second position, the aerosol-forming substrate outlet and the aerosol-forming substrate inlet may not be aligned with each other, so the aerosol-forming substrate cannot pass from the first component to the second component.

[0007] Advantageously, the aerosol-forming substrate outlet and inlet are not aligned at the first position, thereby preventing fluid communication between the storage unit and the aerosol-generating element at the first position. This prevents the aerosol-forming substrate from coming into contact with the aerosol-generating element before it is desired. Aerosol-forming substrate in contact with the aerosol-generating element for extended periods can cause corrosion of the metal parts of the aerosol-generating element.

[0008] The aerosol-forming substrate outlet and aerosol-forming substrate inlet may be formed on opposing parallel walls of the first and second components, respectively. In the first position, the outlet may not be aligned with the inlet, while in the second position, the outlet may be aligned with the inlet along an axis perpendicular to the parallel walls.

[0009] Furthermore, the sliding mechanism may be configured to allow the first component to translate only in a lateral direction perpendicular to an axis perpendicular to the parallel wall.

[0010] The first and second components may be joined by a sliding mechanism. Advantageously, the first and second components are in contact with each other. The first component may comprise at least a portion of the sliding mechanism. The second component may comprise at least a second portion of the sliding mechanism. The first portion of the sliding mechanism may be configured to engage with the second portion of the sliding mechanism. The first portion of the sliding mechanism may have a projection, and the second portion of the sliding mechanism may have a recess that engages with the projection. The sliding mechanism may include a linear sliding guide. The second portion of the sliding mechanism may have a track, and the first portion of the sliding mechanism may have a guide that engages with the track. Alternatively, the first portion of the sliding mechanism may have a track, and the second portion of the sliding mechanism may have a guide that engages with the track.

[0011] The first component may further comprise a first airflow channel including a first air intake and a first air outlet. The second component may further comprise a second airflow channel including a second air intake and a second air outlet.

[0012] In the first position, the first air intake and the second air outlet may not be aligned with each other, so air cannot pass between the second airflow channel and the first airflow channel. In the second position, the first air intake and the second air outlet may not be aligned with each other, so air cannot pass between the second airflow channel and the first airflow channel.

[0013] The sliding mechanism may be configured to allow the first component to translate laterally with respect to the longitudinal axis of the first airflow channel.

[0014] In the second position, the aerosol generating element can be in fluid communication with the first airflow channel.

[0015] Advantageously, in the first position, both the outlet and inlet of the aerosol-forming substrate, as well as the first air intake and the second air outlet, are not in fluid communication, and therefore the aerosol-forming substrate cannot pass between the first and second components.

[0016] The cartridge may further comprise a fragile member coupled to the first and second components. The fragile member may be configured to resist movement of the first component. The fragile member may be configured to break when sufficient force is applied to break it. Advantageously, the fragile member can prevent accidental translational movement of the first component before first use. The fragile member may be a fragile seal.

[0017] In the first position, the aerosol-forming substrate outlet may be sealed by the second component. This prevents the aerosol-forming substrate from leaking into the second component or out of the cartridge. Preferably, the cartridge further includes a sealing element between the first and second components. The sealing element may be configured to prevent leakage of the aerosol-forming substrate from the first component when the first component is not in the second position. Advantageously, this prevents loss of or access to the aerosol-generating substrate by the user, unless the first component is in the second position. The sealing element may be fixed to the second component. The sealing element may be a substantially flat sheet. The sealing element may contain or be formed from an elastomer. For example, the sealing element may be formed from rubber, silicone, or thermoplastic elastomer (TPE). The sealing element may be fixed to the second component on a wall having the aerosol-forming substrate inlet. The sealing element may have at least one opening to allow fluid movement when the first component is in the second position. The sealing element is preferably a substantially flat sheet including a first opening above the aerosol-forming substrate inlet and a second opening above the second air outlet.

[0018] The first component may include one or more ribs. The one or more ribs may surround the aerosol-forming substrate outlet. When the first component is in the first position, the aerosol-forming substrate outlet may be sealed by one or more ribs pressing against the sealing element. Preferably, the one or more ribs may further surround the first air inlet. When the first component is in the first position, the first air inlet may be sealed by one or more ribs pressing against the sealing element. The one or more ribs may include a rib located between the aerosol-forming substrate outlet and the first air inlet. The rib located between the aerosol-forming substrate outlet and the first air inlet may advantageously be pressed against the sealing element and seal the aerosol-forming substrate outlet from the first air inlet. This may prevent fluid from passing directly between the first air inlet and the aerosol-forming substrate outlet. For example, the rib located between the aerosol-forming substrate outlet and the first air inlet may be pressed against the sealing element and prevent the aerosol-forming substrate from moving directly from the aerosol-forming substrate outlet into the first air inlet.

[0019] When the first component is in the second position, the one or more ribs may be aligned with the first and second openings of the sealing element. Advantageously, this may allow the aerosol-forming substrate to pass from the first component to the second component and air to pass between the second air flow channel and the first air flow channel. Advantageously, in the second position, the rib located between the aerosol-forming substrate outlet and the first air inlet may press against the sealing element between the first sealing element opening and the second sealing element opening and seal the aerosol-forming substrate outlet from the first air inlet.

[0020] Alternatively, the sealing element may be fixed to the first component and the second component may include one or more ribs.

[0021] The sliding mechanism may be configured to allow the first component to translate in a single direction relative to the second component. The one-way translational movement of the first component can advantageously prevent unnecessary back-and-forth sliding that could lead to excessive wear and, consequently, damage to the cartridge. The second component may include a ratchet mechanism that holds the first component in a second position. Alternatively, the first component may include a ratchet mechanism that holds the first component in a second position.

[0022] Optionally, the cartridge may include a locking mechanism that holds the first component in a second position. This can advantageously prevent accidental sliding of the first component relative to the second component during use.

[0023] The first component may further include a retractable member that holds the first component in a second position, the retractable member being configured to be retracted when in the first position and to extend into a cavity of the second component when in the second position.

[0024] The second component may include a capillary material adjacent to the aerosol generating element. The capillary material may be in fluid communication with the aerosol generating element. The capillary material is a material that actively transports liquid from one end to the other. The capillary material delivers the aerosol generating substrate to the aerosol generating element. The capillary material may have a fibrous or spongy structure. Preferably, the capillary material includes a bundle of capillaries. For example, the capillary material may include a plurality of fibers or threads, or other microtubules. The fibers or threads may be generally aligned to transport the aerosol forming substrate toward the aerosol generating element. Alternatively, the capillary material may include a spongy or foamy material. The structure of the capillary material forms a plurality of small holes or tubes through which the aerosol forming substrate can be transported by capillary action. The capillary material may include any suitable material or combination of materials. Examples of suitable materials include sponge or foam materials, ceramic or graphite materials in the form of fibers or sintered powders, foamable metal or plastic materials, and fibrous materials, such as spun or extruded fibers (cellulose acetate, polyester, or bonded polyolefins, polyethylene, terylene or polypropylene fibers, nylon fibers or ceramics). The capillary material may have any suitable capillary action and porosity to be used with different aerosol-forming substrates. The aerosol-forming substrate has physical properties, including but not limited to viscosity, surface tension, density, thermal conductivity, boiling point, and vapor pressure, which enable the transport of the aerosol-forming substrate through the capillary medium by capillary action.

[0025] The aerosol generating element may have a first side and a second side. The first side may be opposite to the second side. The first side may be exposed to a second airflow channel, and the second side may be exposed to a capillary material. The aerosol generating element may include a fluid-permeable material. The fluid may pass through the fluid-permeable material in the form of a liquid or vapor. The second airflow channel may be in fluid communication with the capillary material via the fluid-permeable aerosol generating element.

[0026] The aerosol generating element may include a heating element. Heating the aerosol-forming substrate may cause volatile compounds to be released from the aerosol-forming substrate as vapor. The vapor may then be cooled in an airflow (e.g., in a first airflow channel) to form an aerosol. The heating element may be substantially flat to enable simple manufacturing. Geometrically, the term “substantially flat” heating element is used to refer to a heating element that is substantially a two-dimensional topological manifold. Thus, a substantially flat heating element extends more substantially in two dimensions along its surface than substantially in three dimensions. In particular, the dimensions of a substantially flat heating element in two dimensions within its surface are at least five times its dimensions in three dimensions perpendicular to the surface. An example of a substantially flat heating element is a structure between two substantially parallel virtual surfaces, where the distance between these two virtual surfaces is substantially less than the extension within its surface. In some embodiments, a substantially flat heating element is planar. In other embodiments, a substantially flat heating element is curved along one or more dimensions to form, for example, a dome shape or a bridge shape.

[0027] The aerosol generating element may include a fluid-permeable mesh. The heating element may have a plurality of gaps or openings extending from a second side to a first side through which fluid may pass. The heating element may have a plurality of conductive filaments. Throughout this specification, the term “filament” is used to refer to an electrical path arranged between two electrical contacts. The filaments may be arbitrarily branched and diverged into several paths or filaments, or several electrical paths may merge into one path. The filaments may have a round, square, flat, or any other cross-section. The filaments may be arranged in a straight or curved manner.

[0028] The heating element may be, for example, an array of filaments arranged parallel to each other. Preferably, the filaments may form a mesh. The mesh may be woven or nonwoven. The mesh may be formed using different types of woven or lattice structures. Alternatively, the conductive heating element may consist of an array of filaments or a fabric of filaments. The mesh, array, or fabric of conductive filaments may also be characterized by its ability to hold liquid. The conductive filaments may define gaps between them, which may have a width of 10 to 100 micrometers. Preferably, the filaments are arranged to create capillary action within the gaps so that the liquid that will be vaporized during use is drawn into the gaps, thereby increasing the contact area between the heating element and the liquid aerosol-forming substrate.

[0029] The conductive filaments may form a mesh with a size of 60 to 240 filaments per centimeter (±10 percent). The mesh density is preferably 100 to 140 filaments per centimeter (±10 percent). The mesh density is more preferably about 115 filaments per centimeter. The gap width may be 100 to 25 micrometers, preferably 80 to 70 micrometers, and more preferably about 74 micrometers. The ratio of the mesh opening area to the total mesh area may be 40 to 90 percent, preferably 85 to 80 percent, and more preferably about 82 percent.

[0030] The conductive filament may have a diameter of 8 to 100 micrometers, preferably 10 to 50 micrometers, more preferably 12 to 25 micrometers, and most preferably about 16 micrometers. The filament may have a round cross-section or a flat cross-section.

[0031] The area of ​​the conductive filament mesh, array, or fabric may be small, for example, 50 square millimeters or less, preferably 25 square millimeters or less, and more preferably about 15 square millimeters. The size is selected to allow the heating element to be incorporated into a handheld system. Setting the size of the conductive filament mesh, array, or fabric to 50 square millimeters or less reduces the total power required to heat the conductive filament mesh, array, or fabric while still ensuring that the conductive filament mesh, array, or fabric is in sufficient contact with the liquid aerosol-forming substrate. The conductive filament mesh, array, or fabric may be rectangular, for example, and may have a length of 2 to 10 millimeters and a width of 2 to 10 millimeters. The mesh preferably has dimensions of about 5 millimeters x 3 millimeters.

[0032] The aerosol generating element may be configured to be resistively heated. In other words, the aerosol generating element may be configured to generate heat when an electric current passes through the heating element. The heating element, or a portion thereof, may include or be formed from any material having suitable electrical and mechanical properties, such as a suitable electrical resistive material. Suitable materials include, but are not limited to, semiconductors such as doped ceramics, "conductive" ceramics (e.g., molybdenum disilide), carbon, graphite, metals, alloys, and composite materials made of ceramic and metallic materials. Such composite materials may include doped or undoped ceramics. An example of a suitable doped ceramic is doped silicon carbide. Examples of suitable metals include titanium, zirconium, tantalum, and platinum group metals.

[0033] Suitable alloys include stainless steel, constantan, nickel-containing, cobalt-containing, chromium-containing, aluminum-containing, titanium-containing, zirconium-containing, hafnium-containing, niobium-containing, molybdenum-containing, tantalum-containing, tungsten-containing, tin-containing, gallium-containing, manganese-containing, and iron-containing alloys, as well as nickel, iron, cobalt, stainless steel-based superalloys, Timetal®, iron-aluminum alloys, and iron-manganese-aluminum alloys. Timetal® is a registered trademark of Titanium Metals Corporation (1999 Broadway Suite 4300, Denver Colorado). In composite materials, the electrical resistive material may be embedded in, sealed in, or coated with an insulating material, depending on the required energy transfer dynamics and external physicochemical properties, or vice versa. The heating element, or portion thereof, may include etched metal foil insulated between two layers of inert material. In this case, the inert material may include Kapton®, full-layer polyimide, or mica foil. Kapton® is a registered trademark of EIdu Pont de Nemours and Company (1007 Market Street, Wilmington, Delaware 19898, United States of America). Combinations of materials may be used to improve the control of the resistance of a substantially flat heating element. For example, a material with high resistivity may be combined with a material with low resistivity. This may be advantageous if one of the materials is more beneficial in terms of other respects, such as price, machinability, or other physical and chemical parameters. Advantageously, a substantially flat filament arrangement with increased resistance reduces parasitic losses. Advantageously, a heater with high resistance allows for more efficient use of battery energy.

[0034] The filament is preferably made of wire. The wire is more preferably made of metal, and most preferably made of stainless steel.

[0035] The electrical resistance of the conductive filament mesh, array, or fabric of the heater element is preferably 0.3 to 4 ohms. More preferably, the electrical resistance of the conductive filament mesh, array, or fabric is 0.5 to 3 ohms, and more preferably about 1 ohm. The electrical resistance is preferably 0.5 ohms or more. More preferably, the electrical resistance of the conductive filament mesh, array, or fabric is 0.6 to 0.8 ohms, and most preferably about 0.68 ohms.

[0036] The heating element may be part of a heater assembly. The heater assembly may comprise the heating element and an electrical contact portion electrically connected to the heating element. The electrical contact portion may consist of two conductive contact pads. The conductive contact pads may be located in an area of ​​the edge of the heating element. Preferably, at least two conductive contact pads may be located at the tip of the heating element. The conductive contact pads may be directly fixed to the conductive filaments of the heating element. The conductive contact pads may comprise a tin patch. Alternatively, the conductive contact pads may be integrated with the heating element. The electrical resistance of the mesh, array, or fabric of the conductive filaments is preferably at least an order of magnitude greater than the electrical resistance of the electrical contacts, and more preferably at least two orders of magnitude greater. This ensures that the heat generated by passing current through the heating element is localized in the mesh or array of conductive filaments. When the system is powered by a battery, a low overall resistance to the heating element is advantageous. A low-resistance, high-current system allows for the delivery of high power to the heating element. This allows the heating element to quickly heat the conductive filaments to the desired temperature.

[0037] Alternatively, the heating element may comprise a heating plate in which an array of openings is formed. The openings may be formed, for example, by etching or machining. The plate may be formed of any material having suitable electrical properties, such as the materials described above with respect to the filaments of the heating element.

[0038] The aerosol generating element may include a susceptor element. In other words, the aerosol generating element may be configured to operate by induction heating. During operation, the susceptor may be heated by eddy currents induced within the susceptor. Hysteresis losses may also contribute to induction heating.

[0039] The aerosol generating element may atomize the aerosol-forming substrate by a method other than heating. For example, the aerosol generating element may include a vibrating membrane, or the aerosol-forming substrate may be forced to pass through a fine mesh.

[0040] The aerosol-forming substrate may be liquid. The aerosol-forming substrate may be liquid at room temperature. In this case, the storage section may be described as a liquid storage section. The aerosol-forming substrate may be in another condensed form, such as a solid, or in another condensed form, such as a gel, at room temperature. Volatile compounds may be released by heating the aerosol-forming substrate. Volatile compounds may be released by moving the aerosol-forming substrate through a vibrating element passage. The aerosol-forming substrate may be liquid at room temperature. The aerosol-forming substrate may contain both liquid and solid components. The liquid aerosol-forming substrate may contain nicotine. The nicotine-containing liquid aerosol-forming substrate may be a nicotine salt matrix. The liquid aerosol-forming substrate may contain plant-derived materials. The liquid aerosol-forming substrate may contain tobacco. The liquid aerosol-forming substrate may contain tobacco-containing materials containing volatile tobacco-flavored compounds released from the aerosol-forming substrate upon heating. The liquid aerosol-forming substrate may contain homogenized tobacco materials. The liquid aerosol-forming substrate may contain non-tobacco-containing materials. The liquid aerosol-forming substrate may contain homogenized plant-derived material.

[0041] The liquid aerosol-forming substrate may contain one or more aerosol-forming compounds. The aerosol-forming compounds are any suitable known compound or mixture of compounds that facilitate the formation of a high-density, stable aerosol during use and are substantially resistant to thermal decomposition at the system's operating temperature. Examples of suitable aerosol-forming compounds include glycerin and propylene glycol. Suitable aerosol-forming compounds are well known in the art and include, but are not limited to, polyhydric alcohols (e.g., triethylene glycol, 1,3-butanediol, glycerin), esters of polyhydric alcohols (e.g., glycerol monoacetate, diacetate, or triacetate), and aliphatic esters of monocarboxylic acids, dicarboxylic acids, or polycarboxylic acids (e.g., dimethyl dodecanediol, dimethyl tetradecanediol). The liquid aerosol-forming substrate may contain water, a solvent, ethanol, plant extracts, and natural or artificial flavors. The liquid aerosol-forming substrate may also contain nicotine and at least one aerosol-forming compound. The aerosol-forming compound may be glycerin or propylene glycol. The aerosol-forming body may contain both glycerin and propylene glycol. The liquid aerosol-forming substrate may have a nicotine concentration of about 0.5% to about 10%, for example, about 2%.

[0042] The cartridge may further include a mouthpiece. The first component may include a mouthpiece. Alternatively, the second component may include a mouthpiece. The mouthpiece may be connected to a second air outlet. The mouthpiece may be removable. The user may apply negative pressure to the mouthpiece that draws air from the second air intake to the first air outlet, allowing the aerosol to be drawn out by the user. Alternatively, the cartridge may be configured to allow the user to draw out the first air outlet directly.

[0043] According to another aspect of the present invention, an aerosol generating system is provided. The aerosol generating system may comprise a cartridge according to the first aspect and a control body connected to the cartridge. The control body may comprise a power supply configured to supply power to the aerosol generating element.

[0044] The control unit may include at least one electrical contact element configured to provide an electrical connection to the aerosol generating element when the control unit is connected to the cartridge. The electrical contact element may be elongated. The electrical contact element may be spring-loaded. The electrical contact element may contact an electrical contact pad in the cartridge.

[0045] The control unit may include a control circuit configured to control the power supply from the power source to the aerosol generating element.

[0046] The control circuit may include a microcontroller. Preferably, the microcontroller is a programmable microcontroller. The control circuit may include further electronic components. The control circuit may be configured to regulate the supply of power to the aerosol generating element. Power may be supplied to the aerosol generating element continuously after the system is started, or intermittently, such as with each inhalation. Power may be supplied to the aerosol generating element in the form of current pulses.

[0047] The control unit may include a power supply configured to supply power to the control circuit and the aerosol generating element. Alternatively, the control unit may include a first power supply configured to supply power to the control circuit and a second power supply configured to supply power to the aerosol generating element. The power supply may be a DC power supply. The power supply may be a battery. The battery may be a lithium-based battery, such as a lithium cobalt battery, lithium iron phosphate battery, lithium titanate battery, or lithium polymer battery. The battery may be a nickel-metal hydride battery or a nickel-cadmium battery. The power supply may be another form of charge storage device, such as a capacitor. The power supply may require recharging and may be configured for numerous charge-discharge cycles. The power supply may have a capacity that allows for sufficient energy storage for one or more user experiences; for example, the power supply may have a capacity sufficient to allow continuous aerosol generation for a period of about six minutes, or a multiple of six minutes, corresponding to the typical time it takes to smoke one conventional cigarette. In another embodiment, the power supply may have a capacity sufficient to allow for a predetermined number of puffs or discontinuous startup of the aerosol generating element.

[0048] The control body may be detachably connected to the cartridge. The control body may be connected to a second component of the cartridge. The control body may have a connecting portion for engaging with the connecting end of the cartridge. The control body may be connected to the cartridge via threads on the cartridge mated with corresponding threads on the control body. Alternatively, the control body may be connected to the cartridge via an opening in the cartridge that forms a snap-fit ​​connection with a corresponding projection on the control body. Or, the control body may be connected to the cartridge via an opening in the control body that forms a snap-fit ​​connection with a corresponding projection on the cartridge. The second component of the cartridge may be substantially received within a cavity of the control body.

[0049] The sliding mechanism may be configured to allow the first component to translate laterally with respect to the longitudinal axis of the control body.

[0050] The aerosol generating system may be a handheld aerosol generating system configured to allow the user to inhale the mouthpiece and draw out an aerosol through a first air outlet. The aerosol generating system may be comparable in size to a conventional cigar or cigarette. The aerosol generating system may have an overall length of approximately 25 mm to approximately 150 mm. The aerosol generating system may have an outer diameter of approximately 5 mm to approximately 30 mm.

[0051] Features of one aspect of the present invention may also be applied to other aspects of the present invention.

[0052] As used herein, the term “aerosol” refers to the dispersion of solid particles, or droplets, or combinations of solid particles and droplets, in a gas. Aerosols may be visible or invisible.

[0061] Here, we will further describe the examples with reference to the figures.

[0062] Figure 1 shows a schematic cross-sectional view of the aerosol generating system 500. The aerosol generating system 500 comprises a cartridge 300 and a control body 400. The cartridge includes a first component 100 and a second component 200. In this embodiment, the aerosol generating system 500 is an electrically operated smoking system, often referred to as an e-cigarette system.

[0063] The control unit 400 is portable and is about the size of a conventional cigar or cigarette. The control unit 400 includes a battery 410, such as a lithium iron phosphate battery, and a controller 420 electrically connected to the battery 410.

[0064] The cartridge 300 comprises a first component 100 having a first airflow channel formed between a first air intake 140 and a first air outlet 145. A mouthpiece 115 is mounted above the first air outlet 145. A liquid aerosol-forming substrate is held in a storage section 105. An aerosol-forming substrate outlet 120 is in fluid communication with the storage section 105. The cartridge further comprises a second component 200. The second component 200 comprises a capillary material 250 and an aerosol-forming substrate inlet 220 that is in fluid communication with an aerosol-generating element 230. In this example, the capillary material 250 has a fibrous structure and is formed from polyester, but any suitable material may be used. The aerosol-generating element 230 comprises a substantially planar fluid-permeable mesh heating element formed from a plurality of filaments. Conductive contact pads are fixed to the aerosol-generating element. When the cartridge 300 is connected to the control body 400, the conductive contact pads are electrically connected to two electrical contacts within the control body 400. Power is supplied from the battery 410 to the aerosol generating element 230 via this electrical connection. The second component further comprises a second airflow channel including a second air intake 240 and a second air outlet 245. The aerosol generating element 230 is in fluid communication with the second airflow channel. The aerosol generating element is positioned downstream of the second air intake 240 and upstream of the second air outlet 245.

[0065] Figure 1 shows a cartridge 300 with the first component 100 in the first position. In the first position, the aerosol-forming substrate outlet 120 and the aerosol-forming substrate inlet 220 are not aligned with each other so that the aerosol-forming substrate cannot pass between the second component 200 and the first component 100. In particular, since the aerosol-forming substrate outlet 120 and the aerosol-forming substrate inlet 220 are not in fluid communication, the aerosol-forming substrate cannot pass between them. Thus, the first position can be considered to "seal" the aerosol-forming substrate outlet 120 and the aerosol-forming substrate inlet 220 with respect to each other. This prevents leakage of the aerosol-forming substrate from the first component 100 to the second component 200 and therefore prevents leakage to the aerosol-generating element 230. As one option, the system 500 may be purchased by the user in the first position. Fragile components, such as brittle seals, may be connected to the first component 100 and the second component 200. A component that is prone to breakage may be configured to break when sufficient force is applied. This prevents accidental translation of the first component 100 relative to the second component 200 until the component that is prone to breakage is forcibly broken by the user manually translating the first component 100 relative to the second component 200.

[0066] The sliding mechanism 150 connects the first component 100 to the second component 200. The sliding mechanism 150 is configured to allow the first component 100 to translate from a first position (shown in Figure 1) to a second position (shown in Figure 2) relative to the second component 200. As shown in Figure 1, the sliding mechanism is configured to allow the first component 100 to translate laterally with respect to the longitudinal axis of the first airflow channel.

[0067] The sliding mechanism 150 is configured to allow the first component 100 to translate in a single direction relative to the second component 200. The cartridge 300 may further include a mechanism configured to hold the first component in the second position, such as a ratchet mechanism. Thus, the first component 100 is prevented from being translated multiple times by the user. After the first use, the first component 100 is maintained in the second position. Alternatively, the sliding mechanism 150 may be configured to allow the first component 100 to move back and forth relative to the second component 200. Thus, between uses of the aerosol generating system 500, the user can translate the first component 100 between the first and second positions.

[0068] Figure 2 shows a schematic cross-sectional view of the aerosol generation system equipped with the cartridge shown in Figure 1. In Figure 2, the first component 100 is in the second position, and the cartridge 300 is connected to the control unit 400.

[0069] The control unit 400 is electrically connected to the battery 410 and includes two electrical contacts configured to supply power to the cartridge 300 via electrical connections to corresponding contacts within the cartridge 300. This electrical connection is a wired connection and is not shown in Figure 2. In another embodiment, the contacts may be configured to inductively heat the susceptor within the cartridge 300. The control unit 400 is detachably connected to the cartridge 300. For example, the control unit 400 is connected to the cartridge 300 via an opening in the cartridge 300 that forms a snap-fit ​​connection with a corresponding projection on the control unit 400, this snap-fit ​​connection is not shown in Figure 2.

[0070] When the first component 100 is in the second position, the first air intake 140 and the second air outlet 245 are aligned with each other so that air can pass between the second component 200 and the first component 100. In the second position, the aerosol-forming substrate outlet 120 and the aerosol-forming substrate inlet 220 are aligned with each other. Therefore, the aerosol-forming substrate can pass between the aerosol-forming substrate outlet 120 and the aerosol-forming substrate inlet 220. As a result, the aerosol-forming substrate in the storage unit 105 is in fluid communication with the aerosol-generating element 230 in the second component 200. The aerosol-forming substrate in the storage unit 105 is in fluid communication with the aerosol-generating element 230 via the aerosol-forming substrate outlet 120 in the first component, the aerosol-forming substrate inlet 220 in the second component, and the capillary material 250. In the second position, the aerosol generating element 230 is in fluid communication with the first airflow channel via a second airflow channel. The aerosol generating element 230 comprises a fluid-permeable mesh heating element having a first side and a second side. The first side is exposed to the capillary material 250. The second side is opposite the first side and is exposed to the second airflow channel. The capillary material 250 is configured to transport the aerosol generating substrate to the aerosol generating element 230.

[0071] The user receives the cartridge 300 in a first position. Before first use, the user translates the first component 100 of the cartridge 300 from the first position to the second position relative to the second component 200. The aerosol-forming substrate outlet 120 and the aerosol-forming substrate inlet 220 are formed on the opposing parallel walls of the first component 100 and the second component 200, respectively. The sliding mechanism 150 is configured to allow the user to translate the first component 100 only in a lateral direction perpendicular to an axis perpendicular to the parallel walls.

[0072] Next, the user connects the cartridge 300 to the control body 400 through an opening in the cartridge 300, which forms a snap-fit ​​connection with a corresponding protrusion on the control body 400. This also electrically connects the cartridge 300 to the control body 400. The battery 410 and controller 420 are then electrically connected to the aerosol generating element 230 via two electrical contacts in the control body 400 and via conductive contact pads in the cartridge 300. Alternatively, the aerosol generating element 230 may include a susceptor element. The battery 410 and controller 420 are electrically connected to the inductor. When the user connects the cartridge 300 to the control body 400, the aerosol generating element 230 is inductively coupled to the inductor.

[0073] Alternatively, after connecting the cartridge 300 to the control unit 400, the user can translate the first component 100 from a first position to a second position relative to the second component 200.

[0074] The system shown in Figure 2 illustrates an aerosol generating system 500 in which the first component 100 of the cartridge 300 is in a second position. In this position, the aerosol-forming substrate outlet 120 and the aerosol-forming substrate inlet 220 are aligned with each other so that the aerosol-forming substrate can pass from the first component 100 to the second component 200. The system is configured so that the user can draw an aerosol into their mouth by inhaling or sucking out the first air outlet 145 of the cartridge 300. During operation, when the user inhales through the mouthpiece 115, air is drawn out through the second air intake 240 via the second airflow channel, through the aerosol generating element 230 to the first air intake 140, and then through the first airflow channel to the first air outlet 145. The control circuit 420 controls the supply of power from the battery 410 to the cartridge 300 when the system is activated. This controls the amount and characteristics of the vapor produced by the aerosol generating element 230. The control circuit 420 may include an airflow sensor, and the control circuit may also supply power to the aerosol generating element 230 when the airflow sensor detects that the user is inhaling vapor from the cartridge 300. When the user inhales from the first air outlet 145 of the cartridge 300, the aerosol generating element 230 is activated and generates vapor that is carried along by the airflow passing through the first and second airflow channels. The vapor cools and forms an aerosol, which is then drawn into the user's mouth through the first air outlet 145.

[0075] After using the aerosol generating system, the user may translate the first component 100 from the second position to the first position relative to the second component 200. Alternatively, the sliding mechanism 150 may be configured to allow the first component 100 to translate in a single direction relative to the second component 200.

[0076] Figure 3 shows a cross-sectional view of a cartridge 800 according to a second embodiment of the present invention, comprising a sliding mechanism 650 disposed in the longitudinal direction, with the first component 600 of the cartridge 800 in a first position. The cartridge 800 shown in Figure 3 includes an aerosol-forming substrate outlet 620 and an aerosol-forming substrate inlet 720 formed on opposing parallel walls of the first component 600 and the second component 700, respectively. In the first position shown in Figure 3, the outlet 620 is not aligned with the inlet 720, while in the second position, the outlet 620 is aligned with the inlet 720 along an axis perpendicular to the parallel walls. The sliding mechanism 650 is configured to allow the first component to translate only in a lateral direction perpendicular to the axis perpendicular to the parallel walls. In this embodiment, the parallel walls are parallel to the longitudinal axis of the first airflow channel. Therefore, the sliding mechanism shown in Figure 3 is configured to cause the first component to translate in a direction parallel to the longitudinal axis of the first airflow channel.

[0077] Figure 4 shows a cartridge 800 having a longitudinal sliding mechanism 650 in which the first component 600 of the cartridge 800 is in the second position. The aerosol-forming substrate outlet 620 and the aerosol-forming substrate inlet 720 are aligned with each other so that the aerosol-forming substrate can pass between the first component 600 and the second component 700.

[0078] In this embodiment, the aerosol generating system operates in substantially the same manner as in the first embodiment. The user translates the first component 600 relative to the second component 700 from a first position to a second position, and then connects the cartridge 800 to the control body. When the first component 600 is in the second position, the user inhales smoke from the first air outlet 645. The aerosol generating element 730 is activated and generates vapor from the aerosol-forming substrate. The vapor is carried by the airflow passing through the first and second airflow channels from the second air intake 740. In the airflow channels, the vapor is cooled and forms an aerosol, which is then drawn into the user's mouth through the first air outlet 645. After using the aerosol generating system, the user may translate the first component 600 relative to the second component 700 from the second position to the first position.

[0079] Figure 5 shows an exploded view of a cartridge 1300 according to a third embodiment of the present invention, with the first component 1100 of the cartridge 1300 in its first position. Figure 5 shows an alternative arrangement of the airflow channel and aerosol-forming substrate inlet 1220 compared to that shown in Figure 1. The configuration of the first air intake 1140, first air outlet 1145, second air intake 1240, and second air outlet 1245 relative to the aerosol-forming substrate outlet 1120 and aerosol-forming substrate inlet 1220 differs in the cartridge 1300 of Figure 5 compared to the cartridge of Figure 1. In the cartridge 1300 shown in Figure 5, the second air outlet 1245 is adjacent to the aerosol-forming substrate inlet 1220 in a direction perpendicular to the direction in which the sliding mechanism 1150 is configured to allow the first component 1100 to translate relative to the second component 1200. Figure 5 shows the second component 1200, which includes an elastomer sheet sealing element 1210 configured to prevent leakage of the aerosol-forming substrate from the first component 1100 when the first component 1100 is not in the second position.

[0080] Figure 6 shows an exploded view of the cartridge 1300 from Figure 5, with the first component 1100 of the cartridge 1300 in the second position.

[0081] Figure 7a shows a bottom view of the first component 1100 in Figures 5 and 6. Figure 7a shows that the first air intake 1140 is adjacent to the aerosol-forming substrate outlet 1120 in a direction perpendicular to the direction in which the sliding mechanism 1150 is configured to allow the first component 1100 to translate relative to the second component 1200. The rib 1130 surrounds and lies between the first air intake 1140 and the first substrate outlet 1120.

[0082] Figure 7b shows a top view of the second component of Figures 5 and 6. Figure 7b shows the second air outlet 1245 and the aerosol-forming substrate inlet 1220. A substantially flat elastomer sheet sealing element 1210 is fixed to the second component 1200.

[0083] When the cartridge is assembled and the first component 1100 is in the first position, the sealing element 1210 interacts with the rib 1130 of the first component. The rib 1130 presses against the sealing element 1210. This seals the first air intake 1140 and the aerosol-forming substrate outlet 1120 so that fluid cannot pass between the first component 1100 and the second component 1200, or between the first air intake 1140 and the aerosol-forming substrate outlet 1120. When the first component 1100 is in the second position, the aerosol-forming substrate outlet 1120 aligns with the first opening of the sealing element 1210 above the aerosol-forming substrate inlet 1220. Furthermore, the first air intake 1140 aligns with the second opening of the sealing element 1210 above the second air outlet 1245. Therefore, when the first component 1100 is in the second position, the aerosol-forming substrate can pass between the first component 1100 and the second component 1200. The ribs located between the aerosol-forming substrate outlet 1120 and the first air intake 1140 press against the sealing element 1210 between the first opening in the sealing element and the second opening in the sealing element. This prevents the fluid from passing directly between the first air intake 1140 and the aerosol-forming substrate outlet 1120 when the first component 1100 is in the first or second position.

[0084] Figure 8 shows a schematic cross-sectional view of the cartridge 1300 of Figure 6. As shown in Figure 8, the second air outlet 1245 is adjacent to the aerosol-forming substrate inlet 1220 in a direction perpendicular to the direction in which the sliding mechanism 1150 is configured to allow the first component 1100 to translate relative to the second component 1200. Furthermore, the first air intake 1140 is adjacent to the aerosol-forming substrate outlet 1120 in a direction perpendicular to the direction in which the sliding mechanism 1150 is configured to allow the first component 1100 to translate relative to the second component 1200. The second air intake 1240 is configured so that air enters the second airflow channel in a direction perpendicular to the direction in which air exits the second airflow channel through the second air outlet 1245.

[0085] Figure 9 shows a schematic cross-sectional view of an aerosol generating system 1500 according to a third embodiment of the present invention. The aerosol generating system 1500 in Figure 9 shows the first component 1100 of a cartridge in a second position relative to the second component 1200. The cartridge 1300 is connected to a control body 1400. The second component 1200 of the cartridge 1300 is substantially received within the cavity of the control body 1400. The control body 1400 comprises a battery 1410 and a controller 1420 electrically connected to the battery 1410. The battery 1410 is configured to supply power to the cartridge 1300 via an electrical connection. This electrical connection is a wired connection and is not shown in Figure 9.

[0086] In the third embodiment, the aerosol generating system operates substantially the same way as in the first embodiment. Via the sliding mechanism 1150, the user translates the first component 1100 from a first position to a second position relative to the second component 1200, and then connects the cartridge 1300 to the control body. The user then inhales vapor from the first air outlet 1145. The aerosol generating element 1230 is activated and vaporizes the aerosol-forming substrate. The vapor is carried by the airflow passing through the first and second airflow channels from the second air intake 1240. The vapor is cooled to form an aerosol and drawn into the user's mouth through the first air outlet 1145.
