Description

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

[0002] Technical Field

[0003] The present application relates to the field of aerosol provision, and in particular, to an extractor for an aerosol provision system and an aerosol provision system.

[0004] Background

[0005] Aerosol provision systems typically include a heater and an article containing an aerosol-generating material. The system heats the article through the heater to generate an aerosol for the user to inhale.

[0006] In some aerosol provision systems, such as a central-heating (heating from the inside to the outside of the article) “heat-not-burn” system, a heater like a heating needle is inserted into the inside of the article for heating. Since the article is in direct contact with the heater, residues of the article will adhere to the heater during the heating process. In order to reduce the residues remaining on the heater, most of such current systems are provided with an extractor to facilitate the separation of the article and the heater.

[0007] As shown in Figure 1 , an example aerosol provision system 1 includes an extractor composed of a receiver 10 and a sleeve 11 , a heater 12, and an article 13. The receiver 10 includes a tubular body, and the tubular body defines a receiving chamber 102 for receiving the article. The other end of the receiving chamber 102 is provided with an eyelet 101 through which the heater 12 passes to be inserted into the article 13 for heating. To fix the article 13 and prevent it from falling off the receiving chamber 102 during the heating process, the size of the current receiving chamber 102 is set to tightly clamp the article 13. However, when the article 13 is depleted and needs to be pulled out, the clamping setting may cause the aerosolgenerating material in the article 13 to separate from the wrapping paper, leaving article residues in the receiving chamber 102 which may be difficult to clean. This may affect the hygiene and performance of the system.

[0008] Summary

[0009] Described herein is an extractor for an aerosol provision system and an aerosol provision system, which can apply a variable clamping force to an article, so that the article can be fixed in the extractor or can be easily removed from the extractor. This may reduce the residue remaining in the system, and avoid damaging the article.

[0010] In accordance with a first aspect, there is provided an extractor for an aerosol provision system. The extractor comprises: a receiver, having an opening for receiving an article and a receiving chamber in fluid communication with the opening, and a through hole penetrating the circumferential wall of the receiver, where the through hole has a top end and a bottom end arranged opposite to each other, and the top end is closer to the opening than the bottom end; a receiving groove, located at the outer side of the through hole along the radial direction of the receiver, with the receiving groove having a first end and a second end arranged opposite to each other along the length direction of the receiver, where the first end is closer to the opening than the second end, and the projection of the receiving groove in the radial direction is at least partially overlapped with the through hole; and a clamping member, arranged within the receiving groove and movable along the length direction of the receiving groove. When the clamping member moves from the first end towards the second end along the receiving groove, a transverse length of the clamping member extending into the receiving chamber shows an increasing trend, while when it moves in the opposite direction, the transverse length of the clamping member extending into the receiving chamber shows a decreasing trend.

[0011] The extractor is provided with a clamping member that can move along the receiving groove, and the movement of the clamping member along the receiving groove brings about a change in the transverse length of the clamping member extending into the receiving chamber for receiving the article. This change in the extending transverse length brings about a change in the minimum inner diameter of the receiving chamber, which correspondingly brings about a change in the clamping force applied to the article, so as to fix or easily remove the article. Specifically, when the transverse length extending into the receiving chamber shows an increasing trend, the minimum inner diameter of the receiving chamber becomes smaller, and the clamping member applies a clamping force to the article in the receiving chamber to fix the article and prevent it from falling off the receiving chamber; when the transverse length extending into the receiving chamber shows a decreasing trend, the minimum inner diameter of the receiving chamber becomes larger, and the clamping member reduces or releases the clamping force on the article in the receiving chamber, so that the article can be easily removed from the receiving chamber. This may reduce the residue remaining in the system.

[0012] A groove opening of the receiving groove may face the through hole. The receiving groove may have a guide surface for guiding the movement of the clamping member. Optionally, along an extension direction from the second end towards the first end, the guide surface extends aslant and / or obliquely outwards in the radial direction of the receiver.

[0013] The guide surface may be a groove bottom surface of the receiving groove, or the guide surface may be an end surface where the groove opening of the receiving groove is located, or the guide surface may be a groove side wall of the receiving groove.

[0014] The guide surface of the receiving groove may be a flat surface or a curved surface. A groove side wall of the receiving groove may be provided with a sliding rail. The clamping member may have a guide element inserted into the sliding rail, and the clamping member may move along the receiving groove through the movement of the guide element along the sliding rail.

[0015] The guide element provides guidance for the movement of the clamping member and provides a connection between the clamping member and the receiving groove, preventing the clamping member from falling off the groove opening of the receiving groove.

[0016] A position on the sliding rail close to the first end along the length direction of the receiving groove may be provided with a stop, which may limit the clamping member to move out of the receiving groove.

[0017] The stop provides the maximum displacement of the clamping member along the length direction of the receiving groove, preventing the clamping member from moving out of the port of the receiving groove.

[0018] The second end of the receiving groove may be connected to an outer wall of the receiver.

[0019] The first end of the receiving groove may be a free end. Or, the entire end surface where the groove opening of the receiving groove is located may be connected to the outer wall of the receiver.

[0026] The extractor may comprise a support that is sleeved on the radial outer side of the receiver.

[0027] The support may be provided with a via hole for the receiver to pass through, and the diameter of the via hole may not be greater than the maximum outer diameter of the receiver.

[0028] The circumferential wall of the receiver may be provided with a flange outwards along the radial direction, and the receiver may have the maximum outer diameter at the position where the flange is located. Through the diameter setting of the flange and the via hole, the receiver can be supported at the support to prevent the receiver from moving axially relative to the support. An inner circumferential wall of the support may be provided with a guide groove cooperating with the flange, which may be configured to guide the alignment of the support and the receiver in the circumferential direction.

[0029] The receiving groove may be the flange. In this arrangement, the receiving groove has multiple functions such as providing a guide surface for the movement of the clamping member, providing support and limitation for the receiver on the support, and providing guidance for the movement of the receiver.

[0030] In accordance with a second aspect, there is provided an aerosol provision system, which comprises the extractor disclosed in the above first aspect.

[0031] The aerosol provision system may comprise any one or more or all of the features described above or below.

[0032] The aerosol provision system may comprise an article arranged in the receiving chamber.

[0091] 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, 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.

[0092] 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 aerosolgenerating 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. 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.

[0093] 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.

[0094] 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. Due to the requirement of fixing the article, the article is typically clamped in the receiving chamber of the extractor. However, this clamping arrangement leads to difficulties in removing the article and may cause the residue of the article to remain in the receiving chamber. The extractor disclosed herein includes a receiving groove on the radial outer side of the receiving chamber of the extractor and a clamping member that moves along the receiving groove. The movement of the clamping member along the receiving groove changes the transverse length of the clamping member extending into or out of the receiving chamber, thereby bringing about a change in the clamping force applied to the article. Based on the change in the clamping force, the article can be fixed in the receiving chamber or easily removed from the receiving chamber to reduce the residue remaining in the system.

[0095] As used herein, an article may be an article comprising aerosol generating material.

[0096] Embodiment 1

[0097] Figures 2 and 3 are three-dimensional structural diagrams of an extractor for an aerosol provision system, shown from different perspectives. Figure 4 is an exploded view of the extractor shown in Figures 2 and 3, and Figure 5 is a cross-sectional view of the extractor shown in Figures 2 and 3 from one viewing direction. Figure 6 is a cross-sectional view of another extractor for an aerosol provision system, which has a different arrangement of the receiving groove from that in Figures 2 and 3. It should be understood that the extractors shown in Figures 2 to 6 are only provided as examples, and other modifications may also be adopted.

[0098] As shown in Figures 2 to 6, the extractor 20 comprises a receiver 210. The receiver 210 has a first opening 211 for receiving an article (not shown), a receiving chamber 212 in fluid communication with the first opening 211 , and a through hole 213 penetrating its circumferential wall. The through hole 213 has a length extending along the length direction of the receiver 210. Specifically, the through hole 213 has a top end 2131 and a bottom end 2132 arranged opposite to each other, and the top end 2131 is closer to the first opening 211 than the bottom end 2132 in the length direction of the receiver 210. As shown in Figures 2 to 6, the through hole 213 is provided in a substantially strip shape. In an alternative embodiment, the through hole 213 may be provided in a spiral shape, e.g. to match the situation where the article is inserted and removed in a spiral manner.

[0099] The extractor 20 further includes a receiving groove 230 located on the outer side of the through hole 213 along the radial direction of the receiver 210. The receiving groove 230 has a first end 231 and a second end 232 arranged opposite to each other along the length direction of the receiver 210. The first end 231 is closer to the first opening 211 than the second end 232. The projection of the receiving groove 230 in the radial direction of the receiver at least partially overlaps with the through hole 213. That is, the receiving groove 230 provides a path extending to the through hole 213. The extractor 20 further comprises a clamping member 220 arranged within the receiving groove 230 and movable along the length direction of the receiving groove 230. As mentioned above, the receiving groove 230 provides a path extending to the through hole 213. Therefore, the movement of the clamping member 220 along the receiving groove 230 enables the clamping member 220 (or part of the clamping member 220) to pass through the through hole 213 (into the receiving chamber 212) or move out of the through hole 213.

[0100] When the clamping member 220 moves from the first end 231 towards the second end 232 along the receiving groove 230, the transverse length of the clamping member 220 extending into the receiving chamber 212 shows an increasing trend, and when it moves in the opposite direction, the transverse length of the clamping member 220 extending into the receiving chamber 212 shows a decreasing trend. That is, the clamping member 220, the receiving groove 230 and / or the through hole 213 are configured such that the transverse length of the clamping member 220 extending into the receiving chamber 212 increases as the clamping member 220 moves away from the first end 231 and towards the second end 232 along the receiving groove 230, and the transverse length of the clamping member 220 extending into the receiving chamber 212 decreases as the clamping member 220 moves away from the second end 232 and towards the first end 231 along the receiving groove 230.

[0101] It can be understood that the movement of the clamping member 220 along the receiving groove 230 brings about a change in the transverse length of the clamping member 220 extending into the receiving chamber 212. This change in the transverse length of the clamping member 220 extending into the receiving chamber 212 correspondingly brings about a change in the minimum inner diameter of the receiving chamber 212, and further brings about a change in the clamping force applied to the article. That is, when the transverse length of the clamping member 220 extending into the receiving chamber 212 shows an increasing trend (i.e. increases), the minimum inner diameter of the receiving chamber 212 becomes smaller, and the clamping member 220 increases the clamping force applied to the article in the receiving chamber 212 to fix the article and prevent it from falling out of the receiving chamber 212. When the transverse length of the clamping member 220 extending into the receiving chamber 212 shows a decreasing trend (i.e. decreases), the clamping member 220 reduces or releases the clamping force on the article in the receiving chamber 212, so that the article can be easily removed from the receiving chamber 212, reducing the possibility of residue remaining in the system.

[0102] As shown in Figures 2 to 6, the receiver 210 comprises a substantially cylindrical tube body, and its interior defines a substantially cylindrical receiving chamber 212 to receive an article with a corresponding shape, such as a cigarette stick. As described herein a cigarette stick is an article comprising aerosol generating material. In some embodiments, the inner diameter of the receiver 210 is constant along its length to accommodate an article with a constant diameter along its length. However, in some embodiments, the inner diameter of the receiver 210 varies along its length to accommodate an article with a diameter that varies along its length. In other embodiments, the outer diameter of the receiver 210 is constant along its length, while the inner diameter varies along its length. Or conversely, the inner diameter of the receiver 210 is constant along its length, while the outer diameter varies along its length.

[0103] The receiver 210 has two ends arranged opposite to each other along the length direction. One end is provided with the above-mentioned first opening 211 , and the end opposite from the first opening 211 is substantially closed. One or more eyelets 214 (only one is shown in Figure 3) are provided at the substantially closed end, so that one or more heating elements of a heater may extend from the eyelet at the second end into the receiving chamber 212. In addition, the eyelet 214 can also serve as an air inlet for the external air flow to enter the receiving chamber 212. In an alternative embodiment, when a circumferential heating method is adopted, the eyelet 214 may only serve as an air inlet for the external air flow to enter the receiving chamber 212. The substantially closed arrangement is beneficial for the extraction of the article, preventing the residue of the article from falling into the system (e.g. an aerosol provision device or an aerosol provision system of which the extractor is a component) from this end. In addition, the substantially closed end can provide support for the article in the axial direction, facilitating the separation of the article from the heater inserted into it.

[0104] As an alternative to the eyelet 214, the end of the receiver 210 may be fully closed, but with one or more pierceable areas provided on it for one or more heating elements of a heater to pierce through and insert into the receiving chamber 212.

[0105] For a system using circumferential heating, the heater is sleeved on the circumferential side (i.e. on a circumferential wall) of the receiver 210 and does not need to extend into the receiving chamber 212. Therefore, with this arrangement, the end of the receiver 210 away from the first opening 211 can be fully closed and no pierceable area may be provided.

[0106] An air inlet for the external airflow to enter the receiving chamber 212 may be provided on the receiver 210. As described above, the air inlet can be the above-mentioned eyelet 214. In an alternative embodiment, the air inlet can be provided on the circumferential wall of the receiver 210. However, it should be understood that the air inlet can be provided at any suitable position, and the present application does not specifically limit this.

[0107] In the examples shown in Figures 2 to 6, the receiving groove 230 has a groove opening 233 facing the through hole 213. The receiving groove 230 has a guide surface for guiding the movement of the clamping member 220. Along the extension direction from the second end 232 towards the first end 231 , the guide surface extends obliquely outward in the radial direction of the receiver 210. Based on this arrangement, when the clamping member 220 moves from the first end 231 towards the second end 232 along the guide surface, it generally shows a trend of getting closer and closer to the (centre of the) receiving chamber 212, so that the transverse length of the clamping member 220 extending into the receiving chamber 212 through the through hole 213 shows an increasing trend (i.e. such that the transverse length of the clamping member 220 extending into the receiving chamber 212 through the through hole 213 increases). Conversely, when the clamping member 220 moves from the second end 232 towards the first end 231 along the guide surface, it generally shows a trend of getting further and further away from the (centre of the) receiving chamber 212, so that the transverse length of the clamping member 220 extending into the receiving chamber 212 through the through hole 213 shows a decreasing trend (i.e. such that the transverse length of the clamping member 220 extending into the receiving chamber 212 through the through hole 213 decreases).

[0108] As shown in Figures 2 to 6, the receiving groove 230 has a groove bottom 234, a groove side wall 235 extending from the groove bottom 234, and a groove opening 233. Based on this, the guide surface of the present application has a variety of possible position arrangements. Some example arrangements are provided, as follows.

[0109] In some embodiments, as shown in Figures 2 to 5, the guide surface is the groove side wall 235 of the receiving groove 230. Specifically, a sliding rail 2351 can be provided on the groove side wall 235. The sliding rail 2351 is arranged obliquely to define a guide surface that is inclined along the radial direction of the receiver 210. Specifically, the clamping member

[0110] 220 has a guide element 221 inserted into the sliding rail 2351 , and the clamping member 220 moves along the groove side wall 235 through the movement of the guide element 221 along the sliding rail 2351. In this embodiment, the groove bottom 234 of the receiving groove 230 can be provided as a vertical surface along the length direction.

[0111] In some embodiments, as shown in Figure 6, the guide surface is the groove bottom 234 of the receiving groove 230. That is, the groove bottom 234 itself is a surface that is inclined along the radial direction of the receiver 210. Further, as shown in Figure 6, a sliding rail 2351 is provided on the groove side wall, the clamping member 220 has a guide element

[0112] 221 inserted into the sliding rail 2351 , and the clamping member 220 moves along the receiving groove 230 through the movement of the guide element 221 along the sliding rail 2351. The cooperation between the sliding rail 2351 and the guide element 221 provides a specific movement structure for the clamping member 220. This structure can prevent the clamping member 220 from falling out of the groove opening of the receiving groove 230. It can be understood that the sliding rail 2351 has a substantially same inclined path as the groove bottom 234.

[0113] In an alternative embodiment, the guide surface that is inclined along the radial direction of the receiver 210 is the end surface where the groove opening 233 of the receiving groove 230 is located. In embodiments, the guide surface of the receiving groove 230 can be a flat surface or a curved surface. Further, the guide surface can be a smooth surface or a corrugated surface to provide an expected small resistance through the corrugations and enable the user to feel a suitable resistance based on the small resistance.

[0114] The receiving groove 230 has a variety of possible connection arrangements with the receiver 210.

[0115] In one example, the receiving groove 230 is provided independently of the receiver 210. For example, the receiving groove 230 is supported by an additional bracket, so that the receiving groove 230 is provided on the radial outer side of the receiver 210.

[0116] In one example, only a part of the receiving groove 230 is connected to the outer wall of the receiver 210, and this part includes the second end 232. For example, only the second end 232 is connected to the outer wall of the receiver 210, and the first end 231 of the receiving groove 230 and the part between the first end 231 and the second end 232 are provided separately from the outer wall of the receiver 210. Alternatively, only the first end 231 is a free end, and the second end 232 and the part between the first end 231 and the second end 232 are connected to the outer wall of the receiver 210.

[0117] In another way, as shown in Figures 2 to 6, the entire end surface where the groove opening 233 of the receiving groove 230 is located is connected to the outer wall of the receiver 210. Based on this arrangement, the receiving chamber 212 and the receiving groove 230 are in communication to form a larger chamber, and this chamber is sealed in the circumferential direction to prevent the hot air from escaping, improving the heating efficiency. In this way, the end surface where the groove opening 233 of the receiving groove 230 is located can be connected to the outer wall of the edge of the through hole 213 of the receiver 210, or can be connected to the outer wall outside the edge of the through hole 213 of the receiver 210.

[0118] As shown in Figures 2 to 6, in embodiments where the entire end surface where the groove opening 233 of the receiving groove 230 is located is connected to the outer wall of the receiver 210, the first end 231 of the receiving groove 230 is in fluid communication with the first opening 211.

[0119] As shown in Figures 2 to 6, a stop 2352 is formed at a position on the sliding rail 2351 close to the first end 231 along the length direction of the receiving groove 230, which limits the clamping member 220 from moving out of the receiving groove 230 from the first end 231.

[0120] Further, a stop is also formed at a position on the sliding rail 2351 close to the second end 232 along the length direction of the receiving groove 230, which limits the clamping member 220 from moving out of the receiving groove 230 from the second end 232.

[0121] In embodiments, one or more receiving grooves 230 can be provided. In order to provide a more stable clamping force to the article, in some embodiments, at least two receiving grooves 230 are provided and spaced along the circumferential direction of the receiver 210. More preferably, at least two receiving grooves 230 can be provided symmetrically along the radial direction of the receiving chamber 212 to provide a symmetrical clamping force to the article.

[0122] The through hole 213 and the receiving groove 230 have a variety of possible shape arrangements and shape combinations. In one example, as shown in Figures 2 to 6, both the through hole 213 and the receiving groove 230 are provided in a strip shape.

[0123] The clamping member 220 can be arranged to move in a rolling or sliding manner relative to the receiving groove 230. Taking rolling as an example, the clamping member 220 can be provided as a ball or a roller as shown in Figures 2 to 6. The roller can specifically be a friction roller. Taking sliding as an example, the clamping member 220 can be provided as a slider.

[0124] The outermost layer of the article is generally a thin layer of wrapping paper. In an embodiment, the surface of the clamping member 220 facing the receiving chamber 212 is configured as a flexible surface to minimize the abrasion of the wrapping paper of the article.

[0125] In some embodiments, the clamping member 220 is provided as an elastic clamping member. This is beneficial for receiving articles of different sizes in the receiving chamber 212. When the diameter of the article is large, the elastic clamping member can be compressed in the radial direction of the receiving chamber 212 to reduce the thickness extending into the receiving chamber 212. When the diameter of the article is small, the elastic clamping member can extend in the radial direction of the receiving chamber 212 to extend a relatively large thickness into the receiving chamber 212.

[0126] In some embodiments, the extractor further includes a support to provide support in the length direction for the receiver.

[0127] Figure 7 shows a three-dimensional structure of an extractor including a support provided in an embodiment, and Figure 8 shows a cross-sectional view of the extractor shown in Figure 7 from one viewing direction. As shown in Figures 7 and 8, the extractor 20 includes a support 240 sleeved on the radially outer side of the receiver 210, which is used to provide support in the length direction for the receiver.

[0128] The support 240 comprises a base 241 , and a via hole 243 for the receiver 210 to pass through is provided through the base 241. The diameter of the via hole 243 is not greater than the maximum outer diameter of the receiver 210, so as to provide upward (in the direction towards the first opening 211) support for the receiver 210. A flange is provided on the receiving groove 230 extending outwards along the radial direction of the receiver 210, and the receiver 210 has a maximum outer diameter at the position where the flange is located. The flange forms a limit for the receiver 210 to pass through the via hole 243. As shown in Figures 7 and 8, the flange can specifically be defined and formed by the receiving groove 230 connected to the receiver 210. The support 240 further comprises a circumferential wall 242 extending from the base 241. The base 241 and the circumferential wall 242 define a support cavity for accommodating a part of the receiver 210. One end of the support 240 away from the base 241 is an open end surface for the receiver 210 to enter the support cavity. An inner side of the circumferential wall 242 is provided with a guide groove 2421 cooperating with the flange, such as the receiving groove 230, which is configured to guide the alignment of the support 240 and the receiver 210 in the circumferential direction.

[0129] Taking the structure of the extractor shown in Figures 2 to 5 as an example, the use process of the extractor will be described in combination with the movement of the clamping member in the receiving groove. Figures 9 to 11 are schematic diagrams of the positions of the clamping member in different states.

[0130] Initial position: As shown in Figure 9, when an article 30, such as a cigarette stick, is not inserted or has just been inserted into the receiving chamber 212, the clamping member 220 stays at the bottom of the sliding rail 2351 of the receiving groove 230 in the length direction.

[0131] Heating position: As shown in Figure 10, the article 30 is completely inserted into the receiving chamber 212 and contacts the bottom of the receiving chamber 212. At this time, the clamping member 220 stays at the bottom of the sliding rail 2351 in the length direction, and the article 30 is fixed in the receiving chamber 212 by the clamping force applied by the clamping member 220. This position is the same as or approximately the same as the initial position. In this position, the article 30 is clamped and the receiver 210 is in contact with the heater below (not shown), and heating can be started. Therefore, this position can be referred to as the heating position.

[0132] Extraction position: As shown in Figure 11 , when the article 30 is completely exhausted or when the user thinks that the article 30 is about to be completely exhausted, the article 30 is lifted upward. Based on the frictional force between the article 30 and the clamping member 220, the clamping member 220 is lifted upward at the same time and moves radially outwards while being lifted, and the clamping force gradually decreases, until the article 30 is separated from the clamping member 220, at which point the clamping member 220 releases the clamping force on the article 30. At this time, the article 30 can be easily removed from the receiving chamber 212.

[0133] When the article 30 is removed from the receiving chamber 212, the clamping member 220 returns to the above initial position based on the action of gravity.

[0134] It should be noted that the structure and working process shown in Figures 2 to 11 are only an example of the structure and working process of the extractor. In other embodiments, other possible modifications may also be included. For example, an elastic member can be provided to make the initial position of the clamping member the same as or approximately the same as the extraction position, and during the process of inserting the article into the receiving chamber, the clamping member is driven to move to the heating position.

[0135] Embodiment 2

[0136] Embodiment 2 of the present application provides an aerosol provision system. Figure 12 shows a three-dimensional structural diagram of the aerosol provision system, Figure 13 shows a cross-sectional view of the aerosol provision system shown in Figure 12 from one viewing direction, and Figure 14 shows an exploded view of the aerosol provision system shown in Figure 12.

[0137] As shown in Figures 12 to 14, the aerosol provision system 3 includes a housing 40. The housing 40 is generally elongate and defines an elongate internal chamber. The aerosol provision system 3 further includes an upper cover 420. The upper cover 420 defines one end face of the system in the axial direction, and a second opening 410 communicating with the internal chamber of the housing 40 is provided through the upper cover 420. The second opening 410 is used for inserting an article and exposing the article for the user to puff.

[0138] In an embodiment, the aerosol provision system 3 may further include a dust cover provided on the upper cover to cover the second opening 410 when the article is not inserted and to open the second opening 410 when the article is inserted (e.g. to facilitate insertion of the article).

[0139] The aerosol provision system 3 further includes an extractor provided in the internal chamber of the housing 40. The extractor may have a structure the same as or similar to that of the extractor in Embodiment 1.

[0140] With reference to Figures 12 to 14, the extractor includes a receiver 210'. The receiver 210' has a first opening 21 T for receiving an article 30', a receiving chamber 212' in fluid communication with the first opening 21 T, and a through hole 213' penetrating its circumferential wall. The through hole 213' has a length extending along the length direction of the receiver 210'. Specifically, the through hole 213' has a top end and a bottom end arranged opposite to each other, and the top end is closer to the first opening 21 T than the bottom end in the length direction of the receiver 210'.

[0141] The extractor further includes a receiving groove 230' located on the outer side of the through hole 213' along the radial direction of the receiver 210'. The receiving groove 230' has a first end and a second end arranged opposite to each other along the length direction of the receiver 210'. The first end is closer to the first opening 21 T than the second end. The projection of the receiving groove 230' in the radial direction of the receiver at least partially overlaps with the through hole 213'.

[0142] The extractor further includes a clamping member 220' arranged within the receiving groove 230' and movable along the length direction of the receiving groove 230'. When the clamping member 220' moves from the first end towards the second end along the receiving groove 230', the transverse length of the clamping member 220' extending into the receiving chamber 212' shows an increasing trend (i.e. the transverse length of the clamping member 220' extending into the receiving chamber 212' increases), and when it moves in the opposite direction (i.e. from the second end towards the first end along the receiving groove 230’), the transverse length of the clamping member 220' extending into the receiving chamber 212' shows a decreasing trend (i.e. the transverse length of the clamping member 220' extending into the receiving chamber 212' decreases).

[0143] The aerosol provision system 3 further includes an article 30' disposed within the receiving chamber 212' through the first opening 21 T and the second opening 410. The clamping member 220' is configured such that when it moves from the first end towards the second end, the clamping force applied to the article shows an increasing trend (i.e. increases), and when the clamping member moves in the opposite direction (i.e. towards the first end), the clamping force applied to the article shows a decreasing trend (i.e. decreases).

[0144] The aerosol provision system 3 further includes a heater, and the heater includes a heater base 510 and a heating needle 520. The heater base 510 is arranged adjacent to one end of the receiver 210' away from the first opening 21 T. When the receiver 210' is pressed downward, the heating needle 520 passes through the eyelet at the end of the receiver 210' away from the first opening and extends into the interior of the article 30' for heating. The heater base 510 may be arranged to be connected to the inner circumferential wall of the housing 40 to fix the heater and support the receiver 210'.

[0145] The aerosol provision system 3 further includes a power source (not shown in the figures) and a controller (not shown in the figures). The power source supplies power to the heater for heating under the control of the controller.

[0146] The working process of the aerosol provision system 3 is basically the same as the working process of the extractor in Embodiment 1 described above. For details, reference may be made to the description of Embodiment 1 , and it will not be repeated here.

[0147] It should be noted that Figures 12 to 14 only show an example of the structure of the aerosol provision system. Other possible modifications are also included. For example, the extractor may be partially arranged in the chamber of the housing and partially arranged outside the housing. In another example, the extractor, especially the receiver, is detachable relative to the housing for replacement or removal for cleaning. Specifically, the user can replace the receiver while replacing the article.

[0148] Based on the arrangements of the above-mentioned extractor, receiving groove, and clamping member, the clamping or releasing of the article when the clamping member moves relative to the receiving groove is realized, so as to achieve the fixation of the article during heating and the easy extraction of the article after heating, and reduce the residue remaining when the article is extracted. In the description, the referential terminology "an embodiment," "some embodiments," "example," "specific example," or "some examples" means that specific features, structures, materials, or characteristics described in connection with the embodiment or example are comprised in at least one embodiment or example.
