Description

[0001] DEVICE FOR AEROSOL PROVISION SYSTEM AND AEROSOL PROVISION SYSTEM

[0002] Technical Field

[0003] The present application relates to the field of aerosol provision technology, particularly to a device for an aerosol provision system and an aerosol provision system.

[0004] Background

[0005] The current aerosol provision devices are primarily categorized into two types based on their heating methods: core heating and circumferential heating. The core heating may aid baking and heating of the cigarettes used in aerosol provision devices, as well as its ability to achieve a fast rise in heating temperature. The heating modules of the core heating type are mostly planar or pin-shaped. The cigarettes used in aerosol provision devices are primarily made from thin sheets with a high moisture content. When the cigarette is inserted into the heating chamber, the thin sheets come into close contact with the heating needle of the module. Under the high-temperature baking, this may lead to a certain degree of adhesion. The residues that stick to the heating needles and the tobacco crumbs that fall to the bottom of the lifting mechanism are both relatively difficult to clean.

[0006] When cleaning the device, only a brush may be inserted into the heating chamber for a rudimentary cleaning. Currently, when aerosol provision devices are in operation, they typically use high-temperature heating to bake the tobacco. This process generates aerosols that include substances such as smoke agents, moisture, essences, and solvents. These aerosols or the high-temperature-baked tobacco shreds may accumulate and adhere to the surface of the heating module. Simple cleaning with a brush is ineffective in removing these residues. Over time, this significantly impairs the heating efficiency and lifespan of the heating module. Moreover, it may lead to the production of harmful chemical substances, adversely affecting the user experience.

[0007] Summary

[0008] In accordance with some embodiments described herein, there is provided a device for an aerosol provision system and an aerosol provision system.

[0009] According to an aspect, there is provided a device for an aerosol provision system, wherein the device comprises a housing with a first containment chamber, and the top of the first containment chamber along the height direction having an insertion opening; an extractor, internally formed with a second containment chamber for containing a cigarette, is located inside the first containment chamber and is capable of moving upwards along the height direction of the device so as to be disassembled from the insertion opening; a heating module, detachably arranged in the first containment chamber, is located at the bottom of the extractor along the height direction and connected to the extractor, and is capable of following the extractor to move upwards along the height direction of the device so as to be removed from the insertion opening.

[0010] In embodiments of the devices described above, the heating module may be configured to move upward along the height direction of the device in conjunction with the extractor, allowing it to be removed from the insertion opening. This enables the heating module to be detached from the device for cleaning, thereby improving the cleaning effectiveness of the heating module.

[0011] In embodiments of the or any of the above device for an aerosol provision system, the device may further comprise a connecting assembly. The connecting assembly may comprise a first connecting component and a second connecting component. One of the first connecting component and the second connecting component may be arranged on the extractor, and the other one thereof may be arranged on the heating module. The heating module may be detachably connected to the extractor through the connecting assembly.

[0012] In embodiments of any of the devices described above, the use of the first and second connecting components, which may be mutually cooperative within the connecting assembly, may enable a detachable connection between the heating module and the extractor. This allows for further cleaning of the heating module, thereby further enhancing the cleaning effectiveness of the heating module.

[0013] In embodiments of the or any of the above devices for an aerosol provision system, one of the first connecting component and the second connecting component may comprise a protrusion structure, and the other one thereof may comprise a connecting groove that matches the protrusion structure. The protrusion structure may be deformable in a direction towards the inside of the device when squeezed by an external force to detach from the connecting groove.

[0014] By configuring one of the first and second connecting components as a protrusion structure and the other as a connecting groove that matches the protrusion structure, quick installation and detachment between the first and second connecting components may be achieved. This may assist with improving assembly efficiency while maintaining a simple structure, which helps reduce production costs.

[0015] In embodiments of the or any of the above devices for an aerosol provision system, the first connecting component may be a protrusion structure arranged on a side wall of the extractor, and the second connecting component may be a connecting groove arranged on a side wall of the heating module.

[0016] In embodiments of the or any of the above devices for an aerosol provision system, the connecting groove may extend along the circumferential direction of the containment portion, and the protrusion structure may be capable of moving back and forth along the connecting groove.

[0017] By configuring the protrusion structure to move reciprocally along the connecting groove, it may drive the heating module to move relative to the extractor. This causes the cigarette accommodated within the extractor to move relative to the heating module, preventing aerosolgenerating materials from adhering to the heating module (especially the heating needle) or remaining within the chamber. As a result, the hygiene of the device is improved.

[0018] In embodiments of the or any of the above devices for an aerosol provision system, there may be a plurality of protrusion structures and a plurality of connecting grooves with the same quantity. The plurality of protrusion structures and the plurality of connecting grooves may be respectively arranged at intervals on the side wall of the extractor and the side wall of the containment portion.

The guide element may be capable of spirally rotating along the spiral groove, and when the extractor and the heating module may be removed from the sleeve, the heating module rotating with respect to the extractor.

[0024] By utilizing the cooperating spiral groove and the guiding element, when the cigarette (including the extractor and the heating module) is removed from the aerosol provision device after heating, the guiding element moves along the spiral groove, causing the heating module to rotate relative to the extractor. This results in the cigarette rotating relative to the heating module (especially the heating needle), preventing aerosol-generating materials from adhering to the heating needle or remaining within the chamber. As a result, the hygiene of the device is improved.

[0025] In embodiments of the or any of the above devices for an aerosol provision system, an inner wall of the extractor may be formed with a position limit groove, and the position limit groove may extend along the longitudinal direction of the extractor. The device further may comprise a cigarette holder arranged in the second containment chamber, and an outer side wall of the cigarette holder may be provided with a position limit block that matches the position limit groove. The position limit block is capable of moving back and forth in the position limit groove along the longitudinal direction of the extractor.

The aerosol-modifying agent may be provided in an aerosol-modifying agent release component, that is operable to selectively release the aerosol-modifying agent. The aerosol-modifying agent may, for example, be an additive or a sorbent. The aerosolmodifying agent may, for example, comprise one or more of a flavourant, a colourant, water, and a carbon adsorbent. The aerosol-modifying agent may, for example, be a solid, a liquid, or a gel. The aerosol-modifying agent may be in powder, thread or granule form. The aerosol-modifying agent may be free from filtration material.

[0087] An aerosol generator is an apparatus configured to cause aerosol to be generated from the aerosol-generating material. In some embodiments, the aerosol generator is a heater configured to subject the aerosol-generating material to heat energy, so as to release one or more volatiles from the aerosol-generating material to form an aerosol. In some embodiments, the aerosol generator is configured to cause an aerosol to be generated from the aerosol-generating material without heating. For example, the aerosol generator may be configured to subject the aerosol-generating material to one or more of vibration, increased pressure, or electrostatic energy.

[0088] The present disclosure relates to aerosol delivery systems (which may also be referred to as vapour delivery systems) such as nebulisers or e-cigarettes. Throughout the following description the term "e-cigarette" or "electronic cigarette" may sometimes be used, but it will be appreciated this term may be used interchangeably with aerosol delivery system I device and electronic aerosol delivery system I device. Furthermore, and as is common in the technical field, the terms "aerosol" and "vapour", and related terms such as "vaporise", "volatilise" and "aerosolise", may generally be used interchangeably.

[0089] Aerosol delivery systems (e-cigarettes) often, though not always, comprise a modular assembly comprising a reusable device part and a replaceable (disposable / consumable) cartridge part. Often, the replaceable cartridge part will comprise the aerosol-generating material and the vaporiser (which may collectively be called a “cartomizer”) and the reusable device part will comprise the power provision (e.g. rechargeable power source) and control circuitry. It will be appreciated these different parts may comprise further elements depending on functionality. For example, the reusable device part will often comprise a user interface for receiving user input and displaying operating status characteristics, and the replaceable cartridge device part in some cases comprises a temperature sensor for helping to control temperature. Cartridges are electrically and mechanically coupled to the control unit for use, for example using a screw thread, bayonet, or magnetic coupling with appropriately arranged electrical contacts. When the aerosol-generating material in a cartridge is exhausted, or the user wishes to switch to a different cartridge having a different aerosol- generating material, the cartridge may be removed from the reusable part and a replacement cartridge attached in its place. Systems and devices conforming to this type of two-part modular configuration may generally be referred to as two-part systems / devices.

[0090] It is common for electronic cigarettes to have a generally elongate shape. For the sake of providing a concrete example, certain embodiments of the disclosure will be taken to comprise this kind of generally elongate two-part system employing disposable cartridges. However, it will be appreciated that the underlying principles described herein may equally be adopted for different configurations, for example single-part systems or modular systems comprising more than two parts, refillable devices and single-use disposables, as well as other overall shapes, for example based on so-called box-mod high performance devices that typically have a boxier shape. More generally, it will be appreciated certain embodiments of the disclosure are based on aerosol delivery systems which are operationally configured to provide functionality in accordance with the principles described herein and the constructional aspects of systems configured to provide the functionality in accordance with certain embodiments of the disclosure is not of primary significance.

[0091] As described in the technical background, currently, most heating modules and extractors of aerosol provision devices are typically fixed within the device. When cleaning the device, only a brush may be inserted into the heating chamber for a rudimentary cleaning, and the heating module and other components cannot be disassembled separately for thorough cleaning. This may affect the heating efficiency and lifespan of the heating module, and may also lead to the production of harmful chemical substances, negatively impacting the user experience.

[0092] The device may be an aerosol provision device. The device may receive an article comprising aerosol generating material. The cigarette described herein acts as an article comprising aerosol generating material such that any of the devices used herein may be described for use with an article comprising aerosol generating material where use of a cigarette is described.

[0093] Embodiment one

[0094] Figure 1 shows a schematic diagram of the three-dimensional structure of an aerosol provision device for an aerosol provision system, Figure 2 shows a cross-sectional view of the device , Figure 3 shows an exploded view of the device for an aerosol provision system . As shown in Figure 1 to Figure 3, the device for an aerosol provision system comprises a housing 100, an extractor 200, a heating module 300 and a connecting assembly 400, etc. The housing 100 internally forms a first containment chamber 120, and the top of the first containment chamber along the height direction has an insertion opening 110. Components such as the extractor 200, the heating module 300, and the connecting assembly 400 are all accommodated within this first containment chamber 120. The extractor 200 internally formed with a second containment chamber 210 for containing a cigarette. Furthermore, the heating module 300 is detachably arranged within the first containment chamber 120, located at the bottom of the extractor 200 along the height direction and connected to the extractor 200. The heating module 300 is capable of following the extractor 200 to move upwards along the height direction of the device so as to be removed from the insertion opening 110. This allows the heating module 300 to be detached from the device for cleaning, thereby improving the cleaning effectiveness of the heating module. It avoids the impact on the heating efficiency and lifespan of the heating module due to incomplete cleaning, as well as the production of harmful chemical substances that could negatively affect the user experience.

[0095] The extractor comprises a base end and an open end. The top of the extractor corresponds to the open end at the insertion opening. The bottom of the extractor corresponds to the base end. The extractor receives at least a portion of an article comprising aerosol generating material. The cigarette can act as an article comprising aerosol generating material.

[0096] In embodiments, the connecting assembly 400 comprises a first connecting component 410 and a second connecting component 420. The first connecting component 410 and the second connecting component 420 are detachably connected. One of the first connecting component 410 and the second connecting component 420 is arranged on the extractor 200, the other one thereof is arranged on the heating module 300, to achieve a detachable connection between the heating module 300 and the extractor 200. This allows the heating module to be detached from the device for cleaning, improving the cleaning effectiveness of the heating module. It avoids the impact on the heating efficiency and lifespan of the heating module due to incomplete cleaning, as well as the production of harmful chemical substances that could negatively affect the user experience.

[0097] In embodiments, one of the first connecting component 410 and the second connecting component 420 comprises a protrusion structure, the other one thereof comprises a connecting groove that matches the protrusion structure, and the protrusion structure is deformable in a direction towards the inside of the device when squeezed by an external force to detach from the connecting groove. This configuration enables quick installation and detachment between the first connecting component 410 and the second connecting component 420, improving assembly efficiency. Additionally, the simple structure helps reduce production costs.

[0098] In embodiments, the first connecting component 410 is a protrusion structure arranged on the extractor 200, and the second connecting component 420 is a connecting groove arranged on the heating module 300. In embodiments, the first connecting component 410 is a connecting groove arranged on the extractor 200, and the second connecting component 420 is a protrusion structure arranged on the heating module 300.

[0099] In embodiments, the first connecting component 410 is a protrusion structure arranged on the heating module 300, and the second connecting component 420 is a connecting groove arranged on the extractor 200.

[0100] In embodiments, the first connecting component 410 is a connecting groove arranged on the heating module 300, and the second connecting component 420 is a protrusion structure arranged on the extractor 200.

[0101] In embodiments, the connecting groove is circumferential groove, and the protrusion structure is capable of moving back and forth along the circumferential groove.

[0102] Referring further to Figure 3, the first connecting component 410 is a protrusion structure 410 arranged on a side wall of the extractor 200, and the second connecting component 420 is a connecting groove 420 arranged on a side wall of the heating module 300 in an embodiment. In embodiments, the heating module 300 is formed with a containment portion 320, which is arranged on an end portion of the heating module 300 facing the extractor 200. An end of the extractor 200 provided with the protrusion structure is embedded in the containment portion 320. The connecting groove 420 is arranged on a side wall of the containment portion 320, allowing the protrusion structure 410 to snap into the connecting groove 420 when the extractor 200 is embedded in the containment portion 320. This design facilitates a detachable connection between the heating module 300 and the extractor 200. When it is necessary to detach the heating module 300 from the extractor 200 for cleaning, one may compress the protrusion structure 410 causing it to deform inward towards the internal of the device, thereby disengaging from the connecting groove 420.

[0103] Referring to Figure 3 and Figure 4, the heating module 300 comprises a heating needle 310, a containment portion 320, a heater base 330, and a first structural component 340. The heating needle 310 is arranged on the heater base 330 and oriented towards the extractor 200. The heater base 330 is embedded within the first structural component 340. The containment portion 320 is formed at the end of the first structural component 340 that is proximate to the extractor 200, and the surface of the heater base 330 on which the heating needle 310 is mounted forms the bottom wall of the containment portion. Referring further to Figure 3 and Figure 4, the heating needle 310 is arranged at the center of the heater base 330's end face that is oriented towards the extractor 200. It can be understood that by arranging the heating needle 310 at the center of the heater base 330's end face that faces the extractor 200, the heating needle 310 can be centrally located when inserted into the cigarette. This central placement allows the heating needle 310 to evenly heat the cigarette, thereby enhancing the user's sensory experience. It should be noted that embodiments do not specifically limit the shape of the heater base 330. The user can configure it according to the actual needs. In embodiments, the heater base 330 may be designed to match the shape of the first structural component 340. For instance, if the first structural component 340 is a hollow columnar structure, the heater base 330 can also be configured as a columnar structure. This facilitates the embedding of the heater base 330 within the first structural component 340.

[0104] Referring further to Figure 3 and Figure 4, the connecting groove 420 is an elongated groove 420 that extends circumferentially along the sidewall of the containment portion 320 to form a circumferential groove. The protrusion structure 410 is capable of moving back and forth along the connecting groove 420, enabling the heating module 300 and the extractor 200 to rotate relative to each other. This rotation allows the cigarette housed within the extractor 200 to move relative to the heating module 300, preventing the aerosol-generating material from adhering to the heating module 300 (especially the heating needle) or remaining within the chamber, thereby improving the hygiene of the device.

[0105] In embodiments, the number of the protrusion structures and the number of the connecting grooves are not specifically limited. The user can configure it according to the actual needs of the product. For example, to ensure a more reliable connection between the extractor 200 and the heating module 300 and to achieve more stable relative motion, the number of the protrusion structures and the connecting grooves can be set to be the same and include multiple units. Multiple protrusion structures may be arranged at intervals on the sidewall of the extractor 200, and multiple connecting grooves may be arranged at intervals on the sidewall of the containment portion 320. As an illustrative but non-limiting example, the number of the protrusion structures and the number of the connecting grooves in the embodiments are two. The two protrusion structures are oppositely arranged on the sidewall of the extractor 200, and the two connecting grooves are oppositely arranged on the sidewall of the containment portion 320.

[0106] Referring to Figure 4, the connecting groove is provided therein with at least one limiting member 430 in an embodiment. In embodiments, the limiting member 430 may be formed as a protrusion extending from one sidewall of the connecting groove towards the other sidewall; alternatively, the limiting member 430 may be a separate component connected within the connecting groove 420. There are no specific limitations imposed here. By providing at least one limiting member 430 within the connecting groove 420, the range of motion of the protrusion structure 410 within the connecting groove can be restricted. It should be noted that in the embodiments of the present application, the number of the limiting member 430 is not specifically limited. The user can configure it according to the actual needs of the product.

[0107] It can be understood that the connecting groove in embodiments may be a through hole or a blind hole, and no specific limitations are imposed on it in embodiments. In embodiments, adaptive choices can be made according to the actual product. For instance, when the sidewall of the containment portion 320 where the connecting groove is arranged is relatively thin, the connecting groove may be designed as a through hole, and the size of the protrusion structure in the depth direction of the connecting groove may be made greater than the depth of the connecting groove to prevent the protrusion structure from dislodging during its movement along the connecting groove. When the sidewall of the containment portion 320 where the connecting groove is arranged is relatively thick, it allows for a larger depth dimension of the connecting groove, hence designing the connecting groove as a blind hole can also prevent the protrusion structure from dislodging during its movement along the connecting groove.

[0108] Referring further to Figure 3, in embodiments, the housing 100 forms with a first containment chamber 120 for accommodating the extractor 200, the heating module 300, and the connecting assembly 400. The first containment chamber 120 is provided with an insertion opening 110 to facilitate the entry or removal of the extractor 200 and the heating module 300 into or from the first containment chamber 120 through the insertion opening 110.

[0109] Referring to Figure 3 and Figure 5, the extractor 200 comprises an extractor body 220, a second structural component 230, and a cover body 250 in an embodiment. The extractor body 220 internally forms a second containment chamber 210, which means the extractor body 220 is of a hollow structure, designed to accommodate the cigarette. The end of the extractor body 220 near the heating module 300 (i.e., the bottom wall of the second containment chamber 210) is provided with a first through hole 221. The first through hole 221 is configured to allow the heating needle 310 to pass through, enabling the heating needle 310 to enter the interior of the extractor body 220 and thus be inserted into the cigarette housed within the extractor body 220. The second structural component 230 is arranged on the insertion opening 110 and comprises a cooperating first part 231 and a second part 232. The first part 231 is fixedly connected to the extractor body 220, while the second part 232 is arranged between the first part 231 and the cover body 250. Optionally, the second part 232 and the first part 231 may be connected by a snap-fit. The cover body 250 is connected to the second structural component 230 via a snap-fit, and the cover body 250 is provided with a through hole to allow the cigarette to be inserted into the extractor body 220 through this through hole. It is understandable that both the first part 231 and the second part 232 are provided with through holes that communicate with the second containment chamber 210 and the through hole on the cover body 250, facilitating the insertion of the cigarette into the second containment chamber 210 within the extractor body 220.

[0110] In embodiments, the cover body 250 may be removed from the device along with the extractor body 220 and other components. In embodiments, the cover body 250 may be fixedly connected to the second structural component 230 via a snap-fit, allowing the cover body 250 to be removed together with the extractor body 220 and other components when they are taken out of the device. In embodiments, the cover body 250 is detachably connected to the housing 100. When it is necessary to remove the extractor body 220 and other components from the device, the cover body 250 is first detached from the housing 100, and then the extractor body 220 and other components are taken out of the device.

[0111] Referring further to Figure 3 and Figure 5, in embodiments, the device for an aerosol provision system further comprises a cigarette holder 500. The cigarette holder 500 is arranged in the second containment chamber 210 of the extractor 200. The cigarette holder 500 is of a hollow structure, internally forming a fourth containment chamber 510, which is designed to accommodate the cigarette. Specifically, a position limit groove 240 is formed on the inner wall of the extractor body 220, extending longitudinally along the extractor body 220. A position limit block 520 is provided on the outer sidewall of the cigarette holder. The position limit block 520 is used in conjunction with the position limit groove 240, allowing the position limit block 520 to move back and forth longitudinally within the position limit groove 240 of the extractor.

[0112] It can be understood that by adding the cigarette holder 500 and placing the cigarette within the fourth containment chamber 510 formed inside the cigarette holder 500, when the cigarette is removed from the device after heating, the cigarette holder 500 may only move longitudinally along the extractor through the cooperation of the position limit groove 240 and the position limit block 520. This prevents the cigarette from breaking during the removal process and also stops the heating element from causing the cigarette to rotate.

[0113] In embodiments, the cigarette is in interference fit with the cigarette holder 500. The cigarette holder is designed to have an interference fit with the cigarette, ensuring that when the cigarette is removed from the aerosol provision device, the interference fit causes the cigarette holder to move together with the cigarette. In embodiments, the method of the interference fit between the cigarette holder 500 and the cigarette is not limited, and users can configure it according to actual needs. As an illustrative but non-limiting example, in embodiments, a protrusion (not shown in the figures) may be provided on an inner wall of the cigarette holder 500. When a cigarette is put into the cigarette holder 500, the protrusion is in interference fit with the cigarette, ensuring that when the cigarette is removed from the device for an aerosol provision system, the interference fit causes the cigarette holder to move along with the cigarette. In embodiments, the shape and material of the protrusion are not specifically limited. Users can configure them according to the actual product requirements, provided that it does not contradict the inventive concept of this application. As an illustrative but non-limiting example, in embodiments, the protrusion is ring-shaped, arranged circumferentially along the inner wall of the cigarette holder 500.

[0114] It should be noted that in embodiments, the shapes of the extractor body 220 and the cigarette holder 500 are not specifically limited. Users can configure them according to actual needs, provided that it does not contradict the inventive concept of this application. As an illustrative but non-limiting example, the extractor body 220 and the cigarette holder 500 in embodiments may be designed as hollow cylindrical structures.

[0115] It should also be noted that in embodiments, the number of position limit grooves 240 and the number of the position limit blocks 520 are not specifically limited. Users can configure them according to the actual needs of the product, provided that it does not contradict the inventive concept of this application. For instance, to ensure more stable movement of the cigarette holder 500 relative to the extractor 200, the number of position limit grooves 240 and the number of the position limit blocks 520 can be set to be the same and include multiple units. Multiple position limit grooves 240 can be arranged at intervals on the inner wall of the extractor body 220, and multiple position limit blocks 520 can be arranged at intervals on the outer sidewall of the cigarette holder 500. As an illustrative but non-limiting example, the number of the position limit grooves 240 and the number of the position limit blocks 520 in embodiments are two. The two position limit grooves 240 are oppositely arranged on the inner wall of the extractor body 220, and the two position limit blocks 520 are oppositely arranged on the outer sidewall of the cigarette holder 500.

[0116] Referring further to Figure 5, the end of the cigarette holder 500 near the heating module 300 (i.e., the bottom wall of the fourth containment chamber 510) is provided with a second through hole 530. The second through hole 530 is configured to allow the heating needle 310 to pass through, enabling the heating needle 310 to enter the interior of the cigarette holder 500 and thus be inserted into the cigarette housed within the cigarette holder 500. In embodiments, the second through hole 530 may be coaxially arranged with the first through hole 221.

[0117] It can be understood that the position limit groove in embodiments can be a through hole or a blind hole, and no specific limitations are imposed on them in embodiments. In embodiments, adaptive choices can be made according to the actual product. For instance, when the sidewall of the extractor body 220 where the position limit groove is arranged is relatively thin, the position limit groove may be designed as a through hole, and the size of the position limit block in the depth direction of the position limit groove may be made greater than the depth of the position limit groove to prevent the position limit block from dislodging during its movement along the position limit groove. When the sidewall of the extractor body 220 where the position limit groove is arranged is relatively thick, it allows for a larger depth dimension of the position limit groove, hence designing the position limit groove as a blind hole can also prevent the position limit block from dislodging during its movement along the position limit groove.

[0118] Embodiment two The difference from Embodiment one is that, as shown in Figure 6, the device for an aerosol provision system in embodiments further comprises a sleeve 600. And the sleeve 600 is arranged in the first containment chamber 120 and fixed inside the housing 100. The sleeve 600 is of a hollow structure, internally forming a third containment chamber 610, which is designed to accommodate the extractor 200 and the heating module 300. In embodiments, a side wall of the sleeve 600 is provided with a spiral groove 620, and a side wall of the heating module 300 is provided with a guiding element 350. On one hand, after placing the heater base 330 into the first structural component 340, the heater base 330 can be fixed to the first structural component 340 using the guiding member 350. On the other hand, the guiding member 350 can move spirally along the spiral groove 620, while the protrusion structure on the sidewall of the extractor 200 can move along the connecting groove on the sidewall of the heating module 300. Therefore, when removing the extractor 200 and the heating module 300 from the sleeve 600, the heating module 300 can be rotated relative to the extractor 200, causing the cigarette to rotate relative to the heating needle 310. This prevents the aerosolgenerating material from adhering to the heating needle or remaining within the chamber, thereby improving the hygiene of the device.

[0119] In embodiments, the shape of the sleeve 600 is not specifically limited. Users can configure it according to actual needs, provided that it does not contradict the inventive concept of this application. As an illustrative but non-limiting example, the sleeve 600 in embodiments may be designed as a hollow columnar structure.

[0120] In addition to the above, the other structures of the device for an aerosol provision system provided in embodiments are the same as the related structures in Embodiment one. For specific details, please refer to the relevant content in Embodiment 1 , which will not be reiterated here.

[0121] Embodiment three

[0122] The difference from Embodiment one is that, as shown in Figure 7, the device for an aerosol provision system in embodiments further comprises a first conductive element 700 and a second conductive element (not shown in the figures). The first conductive element 700 is arranged on an end of the heating module 300 away from the extractor 200, and the second conductive element (not shown in the figures) is arranged at a position on the first containment chamber 120 facing the heating module 300, and when the heating module 300 is put into the device, the first conductive element 700 is abutted against the second conductive element (not shown in the figures) to form an electric connection.

[0123] In embodiments, one of the first conductive element 700 and the second conductive element (not shown in the figures) is columnar in shape, and the other one thereof is a circular or annular structure. Furthermore, when the first conductive element 700 and the second conductive element (not shown in the figures) rotate within a predetermined angle, the first conductive element 700 and the second conductive element (not shown in the figures) are always in electric connection. Since the heating module 300 in embodiments can be detached from the device, designing the first conductive element 700 and the second conductive element (not shown in the figures) with the above structure can prevent the situation where, upon reinstallation of the heating module 300 into the device, the first conductive element 700 and the second conductive element (not shown in the figures) do not achieve electrical connection due to positional misalignment.

[0124] Referring further to Figure 7, in embodiments, the first conductive element 700 is electrically connected to the heating module 300, and the second conductive element is electrically connected to the battery, enabling the battery to supply power to the heating module 300. Taking as an example the first conductive element 700 being of a columnar structure and the second conductive element (not shown in the figures) being of a circular or annular structure for illustration. In embodiments, an electrode hole 360 is provided at the end of the first structural component 340 away from the extractor 200. One end of the columnar first conductive element 700 passes through the electrode hole 360 to electrically connect with the heater base 330, and the other end of the columnar first conductive element 700 is electrically connected to the circular or annular second conductive element. It is understandable that in embodiments, both the first conductive elements 700 and the second conductive elements include two units. The two first conductive elements 700 are electrically connected to the positive and negative terminals of the heating module 300, respectively, and the two second conductive elements are electrically connected to the positive and negative terminals of the battery, respectively.

[0125] In addition to the above, the other structures of the device for an aerosol provision system provided in embodiments are the same as the related structures in Embodiment one. For specific details, please refer to the relevant content in Embodiment 1 , which will not be reiterated here.
