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, and particularly to an aerosol provision device and an aerosol provision system.

[0004] Technical Background

[0005] Heat-not-burn aerosol provision devices are electronic products designed to mimic traditional cigarettes in terms of smoke, taste, and sensation. These products, also known as "heat-not-burn" products or tobacco heating devices, generate aerosols by heating — rather than combusting — an aerosol generating material, such as a tobacco substrate, which is then inhaled by the user.

[0006] Currently, aerosol provision devices are mainly classified into two types according to their heating methods: core heating and circumferential heating. Core heating may more thoroughly bake and heat the articles used in aerosol provision devices and may raise the heating temperature more rapidly. The heating components of core heating aerosol provision devices are mostly in the form of sheets or pins. The articles used in these devices are mainly made of thin sheets with a relatively high moisture content.

[0007] Summary

[0008] In accordance with an aspect, there is provided an aerosol provision device comprising an extractor component, a heating component, and a connecting component. The extractor component comprises an extractor body configured to accommodate a cigarette stick. The heating component comprises a heating pin configured for insertion into the cigarette stick. The connecting component comprises a spiral groove and a guiding member that mutually cooperate, wherein one of the spiral groove and the guiding member is arranged on the extractor component, and the other is arranged on the heating component. The guiding member moves along the spiral groove, thereby driving the extractor body to rotate relative to the heating pin.

[0009] In some embodiments of any of the above, by utilizing the engagement between the spiral groove and the guiding member in the connecting component, when the cigarette stick is removed from the aerosol provision device after heating, the guiding member moves along the spiral groove, driving the extractor body to rotate relative to the heating pin. As a result, the cigarette stick rotates relative to the heating pin, which may prevent or reduce aerosol generating material adhering to the heating pin or remaining in the chamber, thereby improving the hygiene of the device. In some embodiments of any of the above, the extractor component further comprises a first sleeve in which a first containment chamber is formed. In some embodiments of any of the above, a portion of the heating component is accommodated in the first containment chamber, and the spiral groove is arranged on the side wall of the first sleeve.

[0010] In some embodiments of any of the above, the heating component further comprises a heating element base, with the guiding member arranged on the side wall of the heating element base and the heating pin arranged at the center of the end of the heating element base facing the extractor component.

[0011] By positioning the heating pin at the center of the end of the heating element base facing the extractor component, the heating pin may be inserted into the central position of the cigarette stick, which may provide more uniform heating of the cigarette stick and enhance the user experience.

[0012] In some embodiments of any of the above, the aerosol provision device further comprises a housing in which a limiting groove is formed, and the limiting groove extends longitudinally along the device. A limiting block, which is complementary to the limiting groove, is arranged on the outer side wall of the first sleeve and is configured to move longitudinally back and forth within the limiting groove along the device.

[0013] By providing a limiting block on the outer side wall of the first sleeve that is complementary to the limiting groove, when the cigarette stick is removed from the housing of the aerosol provision device, the first sleeve may be allowed to move longitudinally along the device under the effect of the limiting block and the limiting groove. This may restrict the first sleeve from rotating while permitting its longitudinal movement along the device, which may avoid or reduce issues such as the cigarette stick breaking or being damaged during the removal process.

[0014] In some embodiments of any of the above, the aerosol provision device further comprises a bottom base and a boosting structure. The boosting structure is arranged between the first sleeve or the heating element base and the bottom base, when removing the cigarette stick from the device, the boosting structure applies a force to the first sleeve or the heating element base in the direction opposite to the boosting structure.

[0015] By adding the boosting structure, when removing the cigarette stick from the device, the boosting structure applies a force in the direction opposite to the boosting structure to the first sleeve or the heating element base, which may facilitate the removal of the cigarette stick from the device.

[0016] In some embodiments of any of the above, the boosting structure comprises an elastic component. When removing the cigarette stick from the device, the elastic component applies an elastic force back to boosting structure toward the first sleeve or the heating element base in the direction opposite to the boosting structure. In some embodiments of any of the above, when the cigarette stick is loaded into the device, the sum of the weight of the cigarette stick and the first sleeve or the heating element base and the friction between the guiding member and the spiral groove is greater than the elastic force of the elastic component.

[0017] In some embodiments of any of the above, the boosting structure comprises a first magnetic component arranged on the bottom base and a second magnetic component arranged on the first sleeve or the heating element base, wherein the first magnetic component magnetically repels with the second magnetic component.

[0018] In some embodiments of any of the above, when the cigarette stick is loaded into the device, the sum of the weight of the cigarette stick and the first sleeve or the heating element base and the friction between the guiding member and the spiral groove is greater than the repulsive force between the first magnetic component and the second magnetic component.

[0019] In some embodiments of any of the above, the heating component further comprises a heating element base, with the heating pin arranged on the surface of the heating base facing the extractor component; and a second sleeve, fixedly connected to the heating element base. In some embodiments of any of the above, a second containment chamber is formed inside the second sleeve. In some embodiments of any of the above, the heating pin and the extractor component are accommodated within the second containment chamber. In some embodiments of any of the above, the spiral groove is opened on the side wall of the second sleeve. In some embodiments of any of the above, the guiding member is arranged on the side wall of the extractor body.

[0020] By utilizing the spiral groove and guiding member that are engaged with each other in the connecting component, when the cigarette stick is removed from the aerosol provision device after heating, the guiding member moves along the spiral groove, driving the extractor body to rotate relative to the second sleeve. This causes the cigarette stick to rotate relative to the heating pin, which may prevent or reduce aerosol generating material sticking to the heating pin or remaining in the chamber, thereby improving the hygiene of the device.

[0021] In some embodiments of any of the above, a protrusion structure is formed on the inner wall of the extractor body. When a cigarette stick is loaded into the extractor body, the protrusion structure has an interference fit with the cigarette stick.

[0022] By forming a protrusion structure on the inner wall of the extractor body and making the protrusion structure have an interference fit with the cigarette stick loaded into the extractor body, the interference fit may cause the extractor body to move together when the cigarette stick is removed from the aerosol provision device.

[0023] In some embodiments of any of the above, the protrusion structure may be annular in shape. In some embodiments of any of the above, the spiral groove may be a through hole or a blind hole.

[0024] In some embodiments of any of the above, the number of the spiral grooves and the number of the guiding members are both two.

[0025] In accordance with an aspect, there is provided an aerosol provision system, which includes an aerosol provision device according to any of the preceding embodiments.

[0026] In some embodiments of any of the above, the aerosol provision device comprises: an extractor component, comprising an extractor body for accommodating a cigarette stick; a heating component, comprising a heating pin for insertion into a cigarette stick; and a connecting component, comprising a spiral groove and a guiding member that cooperate with each other, with one of the spiral groove and the guiding member arranged on the extractor component and the other arranged on the heating component; the guiding member can move along the spiral groove to drive the rotation of the extractor body relative to the heating pin. Using the spiral groove and the guiding member that cooperate with each other, when the cigarette stick is removed from the aerosol provision device after heating, the guiding member may move along the spiral groove, causing the extractor body to rotate relative to the heating pin, so that the cigarette stick rotates relative to the heating pin. This can prevent or reduce aerosol - generating material sticking to the heating pin or remaining in the chamber, thereby improving the hygiene condition of the device.

[0027] According to an aspect, there is provided an aerosol provision device, the device comprising: an extractor component, comprising an extractor body arranged to accommodate at least a portion of an article comprising aerosol generating material; a heating component, comprising a heating pin arranged to be inserted into the article comprising aerosol generating material; a connecting component, comprising a spiral groove and a guiding member configured to mutually cooperate, one of the spiral groove and the guiding member being arranged on the extractor component and the other of the spiral groove and the guiding member being arranged on the heating component; the guiding member being configured to move along the spiral groove to drive rotation of the extractor body relative to the heating pin.

[0028] According to an aspect, there is provided an aerosol provision system comprising an aerosol provision device according to any of the above embodiments and an article comprising aerosol generating material.

In some embodiments, the support comprises a susceptor. In some embodiments, the susceptor is embedded within the material. In some alternative embodiments, the susceptor is on one or either side of the material.

[0075] A consumable is an article comprising or consisting of aerosol generating material, part or all of which is intended to be consumed during use by a user. A consumable may comprise one or more other components, such as an aerosol generating material storage area, an aerosol generating material transfer component, an aerosol generation area, a housing, a wrapper, a mouthpiece, a filter and / or an aerosol-modifying agent. A consumable may also comprise an aerosol generator, such as a heater, that emits heat to cause the aerosol generating material to generate aerosol in use. The heater may, for example, comprise combustible material, a material heatable by electrical conduction, or a susceptor.

[0076] A susceptor is a material that is heatable by penetration with a varying magnetic field, such as an alternating magnetic field. The susceptor may be an electrically-conductive material, so that penetration thereof with a varying magnetic field causes induction heating of the heating material. The heating material may be magnetic material, so that penetration thereof with a varying magnetic field causes magnetic hysteresis heating of the heating material. The susceptor may be both electrically-conductive and magnetic, so that the susceptor is heatable by both heating mechanisms. The device that is configured to generate the varying magnetic field is referred to as a magnetic field generator, herein.

[0077] An aerosol-modifying agent is a substance, typically located downstream of the aerosol generation area, that is configured to modify the aerosol generated, for example by changing the taste, flavour, acidity or another characteristic of the aerosol. The aerosolmodifying 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 aerosol-modifying 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, ora gel. The aerosol-modifying agent may be in powder, thread or granule form. The aerosol-modifying agent may be free from filtration material.

[0078] 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.

[0079] 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 / device and electronic aerosol delivery system / 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.

[0080] 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.

[0081] 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.

[0082] As described in the background art, most of the current aerosol provision devices are used directly without a cover or after manually opening the cover. On the one hand, this results in a single user experience. On the other hand, it is easy for minors or others to use the devices by mistake, posing a low - safety risk. Moreover, they are prone to being accidentally activated, with a risk of scalding, so the safety level is low.

[0083] Fig. 1 is a schematic perspective view of an aerosol provision device. Fig. 2 is a cross- sectional view of the aerosol provision device, and Fig. 3 is an exploded view of the aerosol provision device. As shown in Figs. 1 to 3, the aerosol provision device comprises a housing 100, an extractor component 200, a heating component 300, and a connecting component 400. The housing 100 defines an accommodating space, and components such as the extractor component 200, the heating component 300, and the connecting component 400 are all accommodated in this accommodating space. The extractor component 200 comprises an extractor body 210. The extractor body 210 has a hollow structure and is configured to accommodate an article comprising aerosol generating material. The heating component 300 comprises a heating pin 310. The heating pin 310 is configured to be inserted into the article to heat the article. The connecting component 400 comprises a spiral groove 410 and a guiding member 420. The guiding member 420 is configured to move along the spiral groove 410. One of the spiral groove 410 and the guiding member 420 is arranged on the extractor component 200, and the other is arranged on the heating component 300. The guiding member 420 is configured to move along the spiral groove 410 to drive relative rotation between the extractor body 210 and the heating pin 310 when the article is taken out of the aerosol provision device. As a result, the article rotates relative to the heating pin, which may prevent or reduce aerosol generating material sticking to the heating pin or remaining in the chamber, thereby improving the hygiene condition of the device.

[0084] With further reference to Fig. 3, in addition to the extractor body 210, the extractor component 200 also comprises a first sleeve 220. The first sleeve 220 may be omitted. The first sleeve 220 has a hollow structure, and defines a first containment chamber 230. A portion of the heating component 300 is accommodated in the first containment chamber 230, and the spiral groove 410 is formed on the side wall of the first sleeve 220. It should be noted that in the embodiments of the present application, the shapes of the extractor body 210 and the first sleeve 220 are not specifically limited. Both the extractor body 210 and the first sleeve 220 in the embodiments of the present application are hollow cylindrical structures. In embodiments, the extractor body and the first sleeve 220 may be any suitable shape.

[0085] The spiral groove 410 may be a through hole or a blind hole. In embodiments in which the side wall of the first sleeve 220 where the spiral groove 410 is arranged is relatively thin, the spiral groove 410 may be a through - hole, and the dimension of the guiding member 420 in the depth direction of the spiral groove 410 may be greater than the depth of the spiral groove 410 to prevent the guiding member 420 from falling out of the spiral groove 410 during its movement along the spiral groove 410. In embodiments in which the side wall of the first sleeve 220 where the spiral groove 410 is arranged is relatively thick, the depth of the spiral groove 410 may have a larger dimension. Implementing the spiral groove 410 as a blind hole may also prevent the guiding member 420 from falling out of the spiral groove 410 during its movement along the spiral groove 410.

[0086] With further reference to Fig. 3, the heating component 300 comprises a heating element base 320, and the guiding member 420 is arranged on the side wall of the heating element base 320. After inserting the article into the extractor body 210, the heating element base 320 is at least partly accommodated in the first sleeve 220. In embodiments, the heating element base 320 is fully accommodated in the first sleeve 220 after inserting the article into the extractor body 210. One end of the extractor body 210 close to the heating element base 320 abuts against the heating element base 320 and is partially accommodated in the first sleeve 220. When removing the article (including the extractor body 210) from the aerosol provision device, the guiding member 420 on the side wall of the heating element base 320 moves along the spiral groove 410 on the side wall of the first sleeve 220. This drives the extractor body 210 to move outward of the aerosol provision device and rotate relative to the heating pin 310. As a result, the article (including the extractor body 210) rotates relative to the heating pin 310, which can prevent or reduce aerosol generating material sticking to the heating pin or remaining in the cavity, thereby improving the hygiene condition of the device.

[0087] In embodiments, the number of the spiral grooves 410 and the guiding members 420 differ from the illustrated embodiment. The number of both the spiral grooves 410 and the guiding members 420 may be two. That is, in embodiments, the spiral groove is a first spiral groove and the connecting component comprises a second spiral groove. In embodiments, the guiding member is a first guiding member and the connecting component comprises a second guiding member. This may make the movement of the heating element base 320 relative to the first sleeve 220 more stable. The two spiral grooves 410 are oppositely arranged on the side wall of the first sleeve 220, and the two guiding members 420 are oppositely arranged on the side wall of the heating element base 320.

[0088] With further reference to Fig. 3, the heating pin 310 is arranged at the center of the end of the heating element base 320 facing the extractor component 200. By arranging the heating pin 310 at the center of the end of the heating element base 320 facing the extractor component, when the heating pin 310 is inserted into the article, it may be arranged at the center of the article. Thus, the heating pin 310 may heat the article evenly, improving the user's taste experience The heating element base 320 may have any suitable shape. In embodiments, the heating element base 320 is adapted to the shape of the first sleeve 220. For example, when the first sleeve 220 is a hollow cylindrical structure, the heating element base 320 may be arranged as a cylindrical structure, which may facilitate the movement of the heating element base 320 relative to the first sleeve 220.

[0089] With further reference to Figs. 2 and 3, the aerosol provision device comprises a lower base 500 and a boosting structure 600. Both the lower base 500 and the boosting structure 600 are arranged in the accommodating space formed inside the housing 100.The lower base 500 is fixedly arranged relative to the housing 100, and the boosting structure 600 is arranged between the heating element base 320 and the lower base 500. By adding the boosting structure 600, when taking out the article from the device, the boosting structure 600 can be used to apply a force in a direction opposite to the boosting structure 600 to the heating element base 320, making it easier to take out the article and the extractor body 210 from the device. In embodiments, the force is applied in the longitudinal direction of the device.

[0090] In embodiments the boosting structure 600 may comprise any known structure that can apply a force in the direction opposite to the boosting structure 600 to the heating element base 320 when taking out the article from the device. In embodiments, the boosting structure 600 comprises an elastic component. Elastic components include but are not limited to springs. Thus, when taking out the article from the device, the elastic force of the elastic component itself is used to apply a force in the direction opposite to the boosting structure 600 to the heating element base 320. When the article is loaded into the device, the sum of the weight of the article and the heating element base 320 and the friction between the guiding member 420 and the spiral groove 410 is greater than the elastic force of the elastic component. When removing the article from the aerosol provision device, as the guiding member 420 on the side wall of the heating element base 320 moves along the spiral groove 410 on the side wall of the first sleeve 220, it drives the extractor body 210 to move outward of the aerosol provision device and rotate relative to the heating pin 310. Therefore, in embodiments, when the boosting structure 600 is an elastic component such as a spring, when the article is loaded into the device, the sum of the weight of the article, the extractor body 210, and the heating element base 320 and the friction between the guiding member 420 and the spiral groove 410 is greater than the elastic force of the elastic component.

[0091] In embodiments, the boosting structure 600 comprises a magnetic component (not shown). The magnetic component comprises a first magnetic component (not shown) arranged on the lower base 500 and a second magnetic component (not shown) arranged on the heating element base 320. The first magnetic component and the second magnetic component are magnetically repulsive, so as to apply a force in the direction opposite to the boosting structure 600 to the heating element base 320 by using the repulsive force between the first magnetic component and the second magnetic component when taking out the article from the device. When the article is loaded into the device, the sum of the weight of the article and the heating element base 320 and the friction between the guiding member 420 and the spiral groove 410 is greater than the repulsive force between the first magnetic component and the second magnetic component. When taking out the article from the aerosol provision device, as the guiding member 420 on the side wall of the heating element base 320 moves along the spiral groove 410 on the side wall of the first sleeve 220, it drives the extractor body 210 to move outward of the aerosol provision device and rotate relative to the heating pin 310. In embodiments in which the boosting structure 600 comprises an elastic component such as a spring, when the article is loaded into the device, the sum of the weight of the article, the extractor body 210, and the heating element base 320 and the friction between the guiding member 420 and the spiral groove 410 is greater than the repulsive force between the first magnetic component and the second magnetic component.

[0092] Referring to Fig. 4, the extractor body 210 defines a hollow structure for accommodating an article comprising aerosol generating material. A through hole 211 is formed on the surface of the end of the extractor body 210 close to the heating component 300. The through hole 211 is configured to allow the heating pin 310 to pass through so that the heating pin 310 can enter the inside of the extractor body 210 and be inserted into the article accommodated in the extractor body 210. A protrusion structure 212 is arranged on the inner wall of the extractor body 210. When the article is loaded into the extractor body 210, the protrusion structure 212 forms an interference fit with the article. This may cause the extractor body 210 to move together with the article to the outside of the aerosol provision device when taking out the article from the aerosol provision device. In embodiments, the protrusion structure may be of any suitable shape and material. In embodiments, the protrusion structure 212 is annular, and the annular protrusion structure 212 is arranged circumferentially along the inner wall of the extractor body 210.

[0093] With further reference to Fig. 3, the aerosol provision device comprises a cover component 700. The accommodating space formed inside the housing 100 has a first opening 110 communicating with the outside of the aerosol provision device. The cover component 700 is arranged at the first opening 110. The cover component 700 is composed of a cover plate 710 and a first structural member 720. The cover plate 710 has a surface facing the user, and the first structural member 720 is embedded in the housing 100. The cover plate 710 and the first structural member 720 are respectively provided with a second opening 711 and a third opening 721. Both the second opening 711 and the third opening 721 are communicated with the first opening 110, and thus communicate with the accommodating space formed inside the housing 100, so that the user can insert the article into the extractor body 210 inside the housing 100 through the second opening 711 and the third opening 721 in sequence.

[0094] With further reference to Fig. 2, the first structural member 720 further forms a third containment chamber 722. The third opening 721 is formed on the bottom wall of the third containment chamber 722, and the size of the third opening 721 is not less than the size of the outer wall of the extractor body 210. One end of the extractor body 210 away from the heating component 300 is accommodated in the third containment chamber 722, and one end of the extractor body 210 away from the heating component 300 can move longitudinally back and forth in the third containment chamber 722. The second opening 711 is formed at a position of the cover plate 710 corresponding to the third containment chamber 722, and the size of the second opening 711 is smaller than the size of the outer wall of the extractor body 210, so as to restrict the extractor body 210 from falling off from the second opening 711.

[0095] Figure 5 shows an exploded view of another aerosol provision device. The aerosol provision device of Figure 5 is similar to the aerosol provision device of Figures 1 to 4 except as described below. The housing 100 comprises an outer shell 120 and a second structural member 130. An accommodating space is formed inside the outer shell 120, and the second structural member 130, the extractor component 200, the heating component 300, and the connecting component 400 are all accommodated in the accommodating space formed inside the outer shell 120.

[0096] As shown in Fig. 6, a fourth containment chamber 150 is formed on the second structural member 130. A limiting groove 140 is provided on the side wall of the fourth containment chamber 150. The limiting groove 140 extends longitudinally along the device, that is, the limiting groove 140 extends along the depth direction of the fourth containment chamber 150 on the side wall of the fourth containment chamber 150. A limiting block 240 is provided on the outer side wall of the first sleeve 220. The limiting block 240 cooperates with the limiting groove 140, and the limiting block 240 can move longitudinally back and forth in the limiting groove 140, thereby driving the first sleeve 220 to move back and forth along the depth direction of the fourth containment chamber 150 within the fourth containment chamber 150.

[0097] By providing the limiting block 240 on the outer side wall of the first sleeve 220 that cooperates with the limiting groove 140, when the article is taken out of the housing 100 of the aerosol provision device, the first sleeve 220 moves longitudinally along the device under the action of the limiting block 240 and the limiting groove 140, so as to restrict the first sleeve 220 from rotating and allow it to move longitudinally along the device, thereby reducing the chance of breakage or damage of the article during the removal process.

[0098] Referring to Fig. 7, although the extractor body 210' is also of a hollow structure for accommodating an article comprising aerosol generating material, and a through hole 21 T is also opened on the surface of the end of the extractor body 210' close to the heating component 300, the through hole 21 T is configured to allow the heating pin 310 and the first sleeve 220 to pass through. After the heating pin 310 passes through the through hole 21 T and enters the inside of the extractor body 210', it may be inserted into the article accommodated in the extractor body 210'. After the first sleeve 220 passes through the through hole 21 T and enters the inside of the extractor body 210', it can abut against the article accommodated in the extractor body 210' and push the article out of the device, facilitating the removal of the article from the device.

[0099] Since the extractor body 210' does not substantially move out of the device with the article when the article is taken out of the device, the extractor body 210' may be fixedly connected to the first structural member 720.

[0100] In embodiments, the number of the limiting grooves 140 and the limiting blocks 240 may vary. In order to make the movement of the first sleeve 220 relative to the second structural member 130 more stable, the number of the limiting grooves 140 and the limiting blocks 240 can both be 2. Among them, 2 limiting grooves 140 are oppositely arranged on the side wall of the fourth containment chamber 150 of the second structural member 130, and 2 limiting blocks 240 are oppositely arranged on the side wall of the first sleeve 220.

[0101] Referring to Fig. 6, the lower base 500 is arranged at one end of the second structural member 130 away from the extractor body 210'. The lower base 500 is formed as the bottom wall of the fourth containment chamber 150. When the boosting structure 600 is an elastic component, the boosting structure 600 is arranged between the first sleeve 220 and the lower base 500, that is, the boosting structure 600 is also arranged in the fourth containment chamber 150, and the two ends of the boosting structure 600 abut against the first sleeve 220 and the lower base 500 (that is, the bottom wall of the fourth containment chamber 150) respectivelyWhen the article is loaded into the device, the sum of the weight of the article and the first sleeve 220 and the friction between the guiding member 420 and the spiral groove 410 is greater than the elastic force of the elastic component. When the boosting structure 600 is a magnetic component, it includes a first magnetic component arranged on the lower base 500 (that is, the bottom wall of the fourth containment chamber 150) and a second magnetic component arranged on the first sleeve 220. The first magnetic component and the second magnetic component are magnetically repulsive. When the article is loaded into the device, the sum of the weight of the article and the first sleeve 220 and the friction between the guiding member 420 and the spiral groove 410 is greater than the repulsive force between the first magnetic component and the second magnetic component. The boosting structure 600 is otherwise similar to the boosting structure of Figures 2 and 3.

[0102] Figs. 8 to 10 show another aerosol provision device. The aerosol provision device of Figures 8 to 10 is similar to the aerosol provision device of Figures 1 to 4 except as described below. The heating component 300' comprises a heating pin 310', a heating element base 320', and a second sleeve 330'. The heating pin 310' is arranged on the surface of the heating element base 320' facing the extractor component 200. The extractor body 210 is also of a hollow structure for accommodating an article comprising aerosol generating material. A through hole is defined on the surface of the end of the extractor body 210 close to the heating component 300. The through hole is configured to allow the heating pin 310' to pass through so that the heating pin 310' can enter the inside of the extractor body 210 and be inserted into the article accommodated in the extractor body 210. The heating pin 310' is at the central position inside the extractor body 210 after passing through the through hole and entering the extractor body 210, so that the heating pin 310' is at the central position of the article when inserted into the article. This may enable the heating pin 310' to uniformly heat the article and improve the user experience.

[0103] Referring to Fig. 10, the second sleeve 330' is of a hollow structure, and a second containment chamber 340' is formed therein. The heating pin 310' and the extractor component 200 are accommodated in the second containment chamber 340'. Further, the heating pin 310' and the extractor body 210 are accommodated in the second containment chamber 340'. The second sleeve 330' is fixedly connected to the heating element base 320'. The spiral groove 410 is defined on the side wall of the second sleeve 330', and the guiding member 420 is arranged on the side wall of the extractor body 210. In embodiments, the extractor body 210 and the second sleeve 330' may be any suitable shapes. In this embodiment, both the extractor body 210 and the second sleeve 330' i are hollow cylindrical structures. By using the mutually - cooperating spiral groove 410 and guiding member 420, when the article is removed from the aerosol provision device after heating, the guiding member 420 moves along the spiral groove 410 to drive the relative rotation between the extractor body 210 and the second sleeve 330', so that the article rotates relative to the heating pin 310', which may prevent or reduce aerosol generating material sticking to the heating pin 310' or remaining in the cavity, thereby improving the hygiene of the device.

[0104] When the article is inserted into the heating chamber, the article comes into close contact with the heating pin of the heating component. Under high temperature baking, a certain degree of adhesion is likely to occur. In prior art systems, after consumers finish puffing, they may separate the article extractor from the aerosol provision device or press the article downward so that the article paper can hold the tobacco shreds, and then rotate the article to separate it from the heating body. These operations may require consumers to master the correct methods. Improper operation may lead to risks such as damage or breakage of the heating pin. In addition, the adhered parts on the heating pin and the tobacco debris that falls to the bottom of the article extractor may be difficult to clean. The above embodiments provide an aerosol provision system which may present a lower risk of damage or breakage of the heating pin and which may require less cleaning or be easier to clean. The above embodiments provide a system in which aerosol generating material may be less likely to remain adhered to the heating pin.

[0105] An aerosol provision system is also provided. The arosol provision system comprises any of the the aerosol provision devices described above and an article comprising aerosol generating material.
