Description

The present invention relates to an extractor for extracting an aerosol generating article placed in an aerosol generating device. The present invention also relates to an aerosol generating device and a mouthpiece containing such an extractor.

A number of prior art documents disclose aerosol generating devices that include, for example, heated aerosol generating systems and electrically heated aerosol generating systems. One advantage of these systems is that they significantly reduce sidestream smoke while allowing the smoker to selectively pause and resume aerosol generation. US Pat. No. 5,144,962 discloses an example of a heated aerosol generating system, which in one embodiment includes a flavor carrier in contact with a heater. In the event that the resource of the specified carrier is exhausted, both it and the heater are replaced. It is desirable to have such an aerosol generating device that allows the substrate to be changed without the need to remove the heating element.

WO 2013/076098 and WO 2016/124550 describe an aerosol-generating device having a heater that is operable to be inserted into an aerosol-generating substrate of an aerosol-generating article, and an extractor to assist in the extraction of the aerosol-generating article after use. These descriptions disclose extractors having a stopper protruding from the outside of the extractor. The stopper is configured to interact with recesses located inside the sleeve, which is located inside the aerosol generating device, and thus with the possibility of connecting the extractor to the aerosol generating device. However, this coupling mechanism, i.e. the interaction of the recesses and the protruding stopper is not always reliable and may deteriorate over time. This can lead to difficulty in removing or separating and reattaching the extractor, and can also adversely affect the stability and usability of the device. Therefore, it would be desirable to provide an improved extractor for assisting in the extraction of an aerosol generating article that does not have these problems.

According to a first aspect of the present invention, an extractor is provided for extracting an aerosol generating article placed in an aerosol generating device. The extractor comprises a housing forming a cavity for placing an aerosol-generating product, and an elastic connecting element attached to the extractor housing. The elastic connecting element is movable relative to the extractor body for detachable connection of the extractor with the section of the aerosol generating device. Preferably, the resilient connecting member is movable independently of the extractor housing to releasably connect the extractor to the aerosol generating device portion.

The term “releasable connection” means that the extractor body is configured to be connected to the aerosol generating device section in such a way that the extractor is substantially fixedly connected to the specified aerosol generating device section, and at the same time the extractor body is configured to be released from the state of fixed connection with a portion of the aerosol generating device so that the extractor body is movable relative to said portion of the aerosol generating device.

The features described in the following preferred embodiments may be provided in any of the aspects of the present invention and in any suitable combination.

By providing an elastic connecting element attached to the extractor body and making said element movable independently of the extractor body, it is possible to repeatedly attach the extractor to and separate from the rest of the aerosol generating device without any deformation of the extractor body. This is due to the fact that only the elastic coupling element will move or deform when entering into interaction and out of interaction of the extractor with the rest of the aerosol generating device. This may mean the advantage that the extractor body will have a longer service life since it will not be subjected to excessive repeated deformation, and the elastic coupling element can be designed in such a way that it is particularly suitable for such repeated deformation. In addition, it is possible to achieve more stable aerosol delivery from puff to puff if the extractor body is not subjected to repeated deformation during use of the aerosol generating device.

This is in contrast to prior art extractors where the bodies have to be subjected to multiple strains when being removed from and inserted into the device, negatively impacting the life of the extractor housing material due to such multiple strains and potentially leading to deterioration and possibly complete failure of the housing. extractor. Such deterioration can also affect the performance of the extractor. In other words, this may adversely affect the ability of the extractor to repeatedly attach to the device. This can adversely affect the user experience of the device.

As used herein, the term "aerosol generating device" refers to a device that interacts with an aerosol-forming substrate to generate an aerosol. The aerosol-generating substrate may be part of an aerosol-generating article. The aerosol generating device may include one or more components used to supply energy from a power source to the aerosol generating substrate to generate an aerosol. For example, the aerosol generating device may be a heated aerosol generating device. The aerosol generating device may be an electrically heated aerosol generating device or a gas heated aerosol generating device. The aerosol generating device may be an aerosol generating device that interacts with the aerosol generating substrate of the aerosol generating article to generate an aerosol that can be directly inhaled into the user's lungs through the user's mouth. The aerosol generating device may be a holder.

In the context of this document, the term "aerosol-generating article" refers to an article containing an aerosol-forming substrate capable of releasing volatile compounds that can form an aerosol. For example, an aerosol-generating article may be an aerosol-generating article that generates an aerosol that is directly inhaled into the user's lungs through the user's mouth. The aerosol generating article may be disposable. In the following, the term "aerosol-generating article" is mainly used.

In the context of this document, the term "aerosol-forming substrate" refers to a substrate capable of releasing volatile compounds that can form an aerosol. Such volatile compounds may be released as a result of heating the aerosol-forming substrate. The aerosol-generating substrate may conveniently be part of an aerosol-generating article or an aerosol-generating article.

Preferably, the aerosol-generating article may be a heated aerosol-generating article, i.e., an aerosol-generating article containing an aerosol-forming substrate that must be heated, rather than combusted, to release aerosol-forming volatile compounds. The aerosol resulting from the heating of the aerosol-forming substrate may contain fewer known harmful constituents than would be produced by combustion or pyrolytic decomposition of the aerosol-forming substrate. The aerosol-generating article may be or contain a tobacco stick.

The body of the extractor is preferably configured to accommodate an aerosol generating article. This means that the cavity formed by the body of the extractor substantially matches the shape or profile of the aerosol generating article it is designed to accommodate.

The extractor body is preferably configured such that particles of the aerosol-generating substrate or other debris that may be generated by the aerosol-generating article are captured or retained within the extractor portion of the aerosol-generating device when the aerosol-generating article is removed. The extractor can then be removed from the device and cleaned in a routine manner to maintain the level of user experience.

The present invention also provides the ability to substantially maintain the integrity of the aerosol generating article while removing the aerosol generating article from the aerosol generating device. The risk of aerosol-generating substrate pieces forming from the aerosol-generating article during removal and retention in the aerosol-generating device is greatly reduced. This provides the advantage that the aerosol generating device will need less frequent cleaning.

Preferably, the extractor body has a first end forming an opening of said cavity and an opposite second end, wherein at least the first section of the elastic connecting element extends in the direction from the first end to the second end. The first section of the elastic connecting element may be elongated. Due to the presence of the hole, it is possible to place the aerosol generating article inside the extractor through the first end.

The distance between the opposite first and second ends of the extractor body forms the longitudinal length of the extractor or the extractor body.

Preferably, the body of the extractor may comprise a surface facing the aerosol-generating article, with the aerosol-generating substrate of the aerosol-generating article correctly positioned within the extractor. This indicates to the user that the aerosol generating article is fully inserted into the extractor housing. This reduces the likelihood of damage to the aerosol-forming substrate during insertion.

Preferably, the first end is an open end and the second end is a substantially closed end. The substantially closed second end may form an end support surface that may provide support or a seat for an aerosol generating article placed within the extractor. Alternatively, both of the first and second ends are open ends, with a support surface for providing a support or seat for the aerosol generating article located within the extractor at a location between said first and second open ends. Preferably, the aerosol generating article substantially bears against the support surface.

The orientation of the resilient coupler thus effected enables efficient multiple attachment and detachment of the extractor without applying excessive strain to the resilient coupler. This is because the opposite second end of the extractor body preferably faces the aerosol generating device when the extractor is connected to the device. Thus, the first section of the elastic connecting element preferably extends in the same direction as the direction of movement required for releasably connecting the extractor body to the aerosol generating device or section thereof. In addition, the first section of the elastic coupling element is subjected to minimal outward bending forces, in particular when the user separates the extractor from the aerosol generating device by pulling it out of the aerosol generating device.

Alternatively, the first portion of the elastic coupling may be oriented in the opposite way. In other words, at least the first section of the elastic connecting element can extend in the direction from the first end to the second end.

The first section of the elastic connecting element may not extend beyond either the first or second end of the housing. Alternatively, the first section of the elastic connecting element may extend beyond either the first or second end of the housing.

The extractor housing may also form an air flow channel to allow air to flow into said cavity. In use, the user may puff on the end of the aerosol-generating article placed in said cavity. The aerosol-generating article comprises an aerosol-generating substrate that is heated by a heater. Air is drawn into said cavity through said air flow channel and flows over the aerosol-forming substrate. The volatile components released from the heated aerosol-forming substrate are entrained in the air stream and condense to form an inhalable aerosol.

Preferably, the first section of the elastic connecting element extends from the near end of the said first section attached to the extractor body to the distal end of the said first section located at a distance from the extractor body.

The proximal end of the first section of the elastic connecting element can be fixed at any point along the body of the extractor. In some embodiments, the implementation of the proximal end of the first section of the elastic connecting element is attached to a point located along the extractor body between the first end of the extractor body and the midpoint along the length of the extractor body.

The distal end of the first section of the elastic connecting element is located in a place located between the first and second ends of the extractor body. Alternatively, the distal end of the first portion of the resilient connector may be located at a location outside either the first or second end of the extractor body such that the resilient connector extends outward from the extractor body.

The first section of the elastic connecting element may have any suitable length. Preferably, the length of the first section of the elastic connecting element is less than the length of the extractor body. In some preferred embodiments, the length of the first portion of the resilient coupler is from about 25 percent to about 75 percent of the length of the extractor body. Such lengths are capable of providing the advantage of being able to incorporate a resilient connector as part of the extractor without any or any significant increase in the footprint of the extractor. Such lengths are also capable of allowing the resilient connector to be properly deflected to releasably connect the extractor to the aerosol generating device.

Preferably, the resilient coupling also includes a second portion having a first end attached to the extractor body and a second end located at a distance from the extractor body.

The first and second sections of the elastic connecting element can be connected to each other. In particular, the second end of the second section may be connected to the proximal end of the first section of the elastic connecting element, or it may be connected to the first section at any other location along it. In such embodiments, the implementation of the first and second sections of the elastic connecting element can be made integral with each other.

Preferably, on the first section of the elastic connecting element there is a protrusion extending away from the extractor body.

The protrusion can be configured to releasably interact with a portion of the aerosol generating device. Said section of the aerosol-generating device may be a housing containing one or more holes or recesses for accommodating the protrusion of the elastic connecting element. Said portion of the aerosol generating device may be any suitable portion which is suitable for receiving an extractor and has suitable means for receiving or interacting with the protrusion of the elastic coupling.

Preferably, the protrusion has a first inclined surface oriented towards the first end of the extractor body and a second inclined surface oriented towards the second end of the extractor body.

Preferably, the second inclined surface has a gentler slope than the first inclined surface.

The protrusion may include a cam element, a tongue, an angled or curved portion, a hook, a pin, a ball, or any other suitable protruding element that can be placed or snapped into a hole or recess. For example, in some preferred embodiments, the implementation of the first section of the elastic connecting element may include a curved section, which is made of the first inclined surface and the second inclined surface.

The first inclined surface of the protrusion may be configured to allow the resilient coupling element to deflect or move towards the extractor body when the extractor is inserted into the aerosol generating device section, so that the extractor can be connected to said device section. In other words, the sliding movement of the extractor within said section of the aerosol generating device causes the elastic connecting element to be pressed against the body of the extractor when the first inclined surface slides along the edge of said section of the aerosol generating device. The steepness of the first inclined surface determines how much force must be applied to deflect the elastic connecting element towards the extractor body when the extractor is inserted into the specified area of the aerosol generating device. The greater the steepness of the first inclined surface, the greater the force required to deflect the elastic connecting element. The steepness of the second inclined surface determines how much force must be applied to deflect the elastic connecting element towards the extractor body when the extractor is released from the state of interaction with the hole or recess of the specified section of the aerosol generating device. The greater the steepness of the second inclined surface, the greater the force required to deflect the elastic connecting element when pulling the specified protrusion from the state of interaction with the hole or recess of the specified section of the aerosol generating device. Thus, the forces required to engage and disengage or to connect and disconnect the extractor and said portion of the aerosol generating device depend essentially on the shape of said protrusion and on the steepness of the first and second inclined surfaces.

Thus, the first and second inclined surfaces of the elastic connecting element respectively determine the forces required for releasable connection and separation of the extractor and the specified section of the aerosol generating device. Preferably, the second inclined surface has a gentler slope than the first inclined surface so as to make it more difficult for the user to accidentally detach the extractor during use of the aerosol generating device. If the first section of the elastic connecting element is oriented in the opposite way, in other words, if at least the first section of the elastic connecting element extends in the direction from the first end to the second end, then preferably the first inclined surface has a gentler slope than the second inclined surface.

Preferably, said protrusion is located near or at the far end of the first section of the elastic connecting element. Alternatively, the protrusion may be provided anywhere along the first portion of the resilient connector.

Preferably, the resilient connecting element is rotatable or bendable relative to the extractor body. The resilient connecting element is preferably rotatable or bendable independently of the extractor body. The elastic connecting element preferably comprises a deflectable or bendable cantilever element. As described above, the resilient coupler, which is movable relative to or independent of the extractor body, ensures that little or no force is transmitted from the resilient coupler to the body when the resilient coupler is deflected or flexed relative to the body. For this reason, the elastic connector can be made from a plastic material, taking into account the high level of flexibility of plastic materials. Other materials such as metals may also be suitable.

Preferably, the elastic connecting element can be pressed in the direction of the offset position. The elastic connecting element may be a spring-loaded device or element. The resilient connecting member may be a resilient projecting member configured to be snap-fitted to said portion of the aerosol generating device. Such an elastic projecting element may be a cantilever, rod or bar. A center of rotation or hinge may be provided on the extractor body such that the resilient coupling member is movable to and from the extractor. If the elastic connecting element comprises a first section and a second section, then a center of rotation or hinge can be provided at the intersection between the first and second parts.

Preferably, the resilient connector comprises a longitudinal extension and is attached to the extractor body such that it has one end that is attached to the extractor body and a distal end located at a distance from the extractor.

Preferably, the elastic connecting element is detachable from the extractor body. This is advantageous in that it thus makes it possible to replace the resilient coupler if it breaks during use, without having to replace the entire extractor body having the non-removable coupler. Replacing the elastic coupling may be cheaper than replacing the entire extractor. This is due to the fact that the elastic connecting element may not be integral with the extractor body. In addition, the inclusion of an elastic connecting element according to the present invention should not significantly affect the manufacture of existing extractors or aerosol generating devices.

Preferably, the extractor also comprises one or more additional resilient connectors, each additional resilient connector being attached to the extractor body and movable relative to the extractor body to releasably connect the extractor to the aerosol generating device portion. Preferably, the extractor also contains one or more additional elastic connecting elements, each of which is attached to the extractor body and is movable independently of the extractor body for releasable connection of the extractor with a portion of the aerosol generating device.

Preferably, the extractor also contains one additional elastic connecting element, which is attached to the extractor body and is movable relative to the extractor body for detachable connection of the extractor with the aerosol generating device section. Preferably, the extractor also contains one additional elastic connecting element, which is attached to the extractor body and is movable independently of the extractor body for detachable connection of the extractor with the aerosol generating device section.

Preferably, the resilient connector and the additional resilient connector or elements are symmetrically located on or around the extractor body. For example, if the extractor body has a substantially circular cross section, then these elastic connectors may be spaced at regular intervals around the circumference of the extractor body.

Each additional resilient connector may have any combination of the features described above with respect to the resilient connector.

According to a second aspect of the present invention, an aerosol generating device capable of receiving an aerosol generating article is provided. Said device comprises: a heating jacket or sleeve containing a heater for heating an aerosol-generating article; and an extractor according to the first aspect of the present invention, wherein said resilient coupling member is configured to releasably connect the extractor to the heating mantle or sleeve.

The aerosol-generating device comprises a heating casing for receiving an extractor, the extractor being slidable inside the heating casing. Preferably, the heating jacket forms part of the jacket of the aerosol generating device. Alternatively, the heating jacket may comprise a separate component configured to be connected to the aerosol generating device.

The heating jacket may include a tube having at least one open end for receiving an extractor and an aerosol generating article placed in the extractor. The extractor body may have a substantially cylindrical shape and form a sliding receptacle, the diameter of which is somewhat less than the diameter of the heating mantle, so that the extractor body can be substantially accommodated in the heating mantle. The extractor body may include a flange configured to abut the end of the heating mantle when the extractor body is fully connected to the heater body.

The heating jacket may also provide a raised track extending longitudinally along the inner surface of the heating jacket. The guide track is configured to interact with the groove or groove located along the outer surface of the extractor. The interaction of the guide track with a corresponding slot in the extractor body ensures that the extractor body does not rotate when placed or slid inside the heating mantle. Alternatively, the heating jacket may also include a guide slot, and the extractor body may have a protrusion configured to engage with the heating jacket guide slot such that the extractor body does not rotate when positioned or slid within the heating jacket.

The heating jacket also provides the container and the heater is configured to be substantially housed within it. In this way, it is possible to reduce the likelihood of the user coming into direct contact with the heater of the device.

The effective diameter of the extractor housing together with the elastic connecting element may be greater than the diameter of the heating jacket.

The aerosol generating device may be an electrically heated aerosol generating system comprising a heater, preferably an electrical heater. Alternatively, the aerosol generating device may be a heated aerosol generating system comprising a gas burner or some other heat source other than electrical. Alternatively, an electrically heated aerosol generating system is provided for housing an aerosol generating article comprising: an aerosol generating substrate, wherein said electrically heated aerosol generating system is configured to accommodate an aerosol generating article and comprises: an electrical heater for heating an aerosol generating substrate ; and an extractor for extracting an aerosol generating article placed in an electrically heated aerosol generating system, said extractor corresponding to any embodiment of the first aspect of the present invention.

The term "electric heater" refers to one or more electrical heating elements. The electrical heater may comprise an internal electrical heating element for at least partially inserting an aerosol-generating article within an aerosol-generating substrate when the aerosol-generating article is placed in an extractor, said extractor being located proximate the heater. An "internal heating element" is an element suitable for insertion or penetration into an aerosol generating material. The present invention is particularly useful when used in combination with an internal heating element, since the aerosol-generating substrate may then tend to stick to the heating element and consequently break during separation of the aerosol-generating substrate from the heating element.

Alternatively or additionally, the electric heater may include an external heating element. The term "outer heating element" refers to an element that at least partially surrounds the aerosol-forming substrate. The electric heater may include one or more internal heating elements and one or more external heating elements.

The electric heater may include one heating element. Alternatively, the electric heater may comprise more than one heating element. The heating element or heating elements may be appropriately positioned to most effectively heat the aerosol-forming substrate.

The electric heater may be of any suitable shape. For example, the electric heater may be in the form of a heating blade. Alternatively, the electrical heater may be in the form of a jacket or substrate with various electrically conductive portions, or in the form of an electrically resistive metal tube. Alternatively, one or more heating needles or rods that pass through the center of the aerosol-forming substrate may be as already described above. Alternatively, the electrical heater may be a disk (end) heater or a combination of a disk heater with heating needles or rods. Other alternatives include a heating wire or filament, such as Ni-Cr (nickel-chromium), platinum, tungsten or alloy wire, or a heating plate. If necessary, the heating element may be applied internally or externally to the solid support material.

The electrical heater may comprise a heat sink or heat reservoir containing a material capable of absorbing and storing heat and subsequently releasing heat over time into the aerosol-forming substrate. The heat sink may be made from any suitable material, such as a suitable metal or ceramic material. In one embodiment, said material has a high heat capacity (sensitive heat storage material) or is a material capable of absorbing and subsequently releasing heat through a reversible process such as a high temperature phase transition. Suitable sensitive heat storage materials include silica gel, alumina, carbon, glass mat, fiberglass, minerals, metal or metal alloy such as aluminium, silver or lead, and cellulosic material such as paper. Other suitable materials that generate heat as a result of a reversible phase change include paraffin, sodium acetate, naphthalene, wax, polyethylene oxide, metal, metal salt, eutectic mixture of salts, or alloy.

The heat sink or heat reservoir may be located such that it is in direct contact with the aerosol-forming substrate and is able to transfer the stored heat directly to the substrate. Alternatively, the heat stored in the heat sink or heat reservoir may be transferred to the aerosol-forming substrate via a heat conductor such as a metal tube.

An electric heater may heat the aerosol-forming substrate by conduction. The electrical heater may be at least partially in contact with the substrate or carrier to which the substrate is applied. Alternatively, heat from an electrical heater may be transferred to the substrate via a heat transfer element.

Alternatively, an electrical heater may transfer heat to incoming ambient air drawn through the electrically heated aerosol generating system during use, and this air in turn heats the aerosol-generating substrate by convection. The ambient air may be heated before it passes through the aerosol-forming substrate.

Preferably, the device includes a mouthpiece. The mouthpiece is formed by a mouthpiece casing, and the extractor is located inside said mouthpiece casing. The mouthpiece is preferably a detachable and replaceable component of the aerosol generating device. It is referred to as the mouthpiece because it is located at the mouth end or downstream end of the device. The mouthpiece preferably refers to a part of the casing of the aerosol generating device and is located at the end of the device. During use, the aerosol-generating article containing the aerosol-generating substrate is preferably partially enclosed within the mouthpiece of the aerosol-generating device. During use, the user does not puff directly on the mouthpiece or mouthpiece casing, but on the aerosol-generating article extending therefrom. Accordingly, the mouthpiece can be considered as forming the most downstream part of the aerosol generating device, and therefore as the part of the device closest to the user's mouth during use. Preferably, the mouthpiece may be manufactured and sold separately to provide the user with the choice of personalizing the device with different mouthpieces having different technical and/or aesthetic features or characteristics.

Preferably, the extractor body is fixedly connected to the mouthpiece so that the extractor body does not move relative to the mouthpiece or mouthpiece housing.

Preferably, the effective diameter of the extractor, i.e., the diameter of the body plus the radial distance from the elastic coupling to the extractor body, is less than the diameter of at least that section of the mouthpiece housing in which the extractor is enclosed. In addition, the mouthpiece housing must also be sized to accommodate at least a portion of the aerosol generating article. There must be a gap inside the mouthpiece casing between the mouthpiece casing and the extractor so that the heating casing can slide inside the mouthpiece casing and the extractor inside the heating casing.

Preferably, the heater extends longitudinally with respect to the device and is configured to penetrate into the interior of the aerosol generating article. Preferably, the heater projects in the longitudinal direction. For example, the heating element is preferably in the form of a heating blade so as to internally heat the aerosol generating substrate of the aerosol generating article placed inside the extractor. In addition, a protruding or elongated heater is easier to clean after use and is easy to replace if damaged or worn.

Preferably, the end of the extractor body contains an opening to allow the heater to be placed in the extractor cavity. Preferably, said opening is provided at the second end of the extractor. Preferably, the second end of the extractor forms a surface for abutting the aerosol generating article against it, and hence for supporting the article within the extractor.

Preferably, the extractor body is slidable within the heating jacket of the aerosol generating device. The extractor body may include a sliding receptacle for receiving an aerosol generating article, slidable within the heating jacket. The terms "extractor body" or "extractor body" may be used throughout this specification interchangeably with the terms "sliding receptacle" or "slidable receptacle".

The resilient nature of the elastic coupling element, when positioned and deflected within the heating jacket, ensures stable and reliable frictional engagement of the connector element with the interior of the heating jacket.

Preferably, the extractor is movable between the first position and the second position when said extractor is connected to the heater body. The first position is an operating position in which the heater passes into the cavity of the extractor, and the second position is an extraction position in which at least a portion of the heater is removed from said cavity.

As described above, the extractor body may include a sliding receptacle for receiving an aerosol generating article. The sliding receiver is thus slidable between the first position and the second position. Preferably, the entire mouthpiece containing the sliding receptacle is movable to move the sliding receptacle between the first position and the second position. Alternatively, only the sliding receptacle of the extractor may be slidable between the first position and the second position.

Preferably, the extractor remains attached to the aerosol generating device or the heater housing while the extractor is in the first and second positions. More preferably, the extractor also remains attached to the aerosol generating device when the extractor is in positions between the first and second positions.

The first position of the sliding receptacle is an operating position in which the heater is capable of heating the aerosol-generating substrate of the aerosol-generating article to form an aerosol. As known to those skilled in the art, an aerosol is a suspension of solid particles and/or liquid droplets in a gas, such as air. The second sliding receptacle position is a withdrawal position that facilitates the removal of the aerosol generating article from the aerosol generating device by the user or consumer. The upstream and downstream ends of the aerosol generating device are defined with respect to the airflow when puffed by the user. Typically, intake air enters the aerosol generating device at the upstream end, mixes with the aerosol, and carries the aerosol in the airstream towards the user's mouth at the downstream end.

Preferably, an aerosol generating article comprising an aerosol generating substrate is provided for the aerosol generating device. In this embodiment, the aerosol generating article remains substantially stationary relative to the sliding receptacle as the sliding receptacle slides between the first position and the second position. The term "substantially immobile" is defined as a change in position by an amount on the order of millimeters during use of the aerosol generating device. The extractor receiver or body and the aerosol generating article move relative to other components of the aerosol generating device, including the heater and the heating jacket. This allows the aerosol generating article to be removed from the aerosol generating device in two steps. In the first step, the aerosol-generating article and the sliding receptacle are moved by sliding while the aerosol-generating substrate is supported relative to the components of the aerosol-generating device, in particular the heater. In a second step, the aerosol generating article, now separated from the heater, can be removed from the sliding receptacle.

Preferably, the heating jacket comprises a first connecting recess or hole and a second connecting recess or hole, wherein when the extractor is in the first position, at least a section of the elastic connecting element interacts with the first connecting recess or hole, and when the extractor is in the second position, at least a section of the elastic connecting element interacts with the second connecting recess or hole.

Preferably, the portion of the resilient connector that interacts with the connector recesses or holes is a protrusion of the resilient connector.

Preferably, the heating jacket includes one or more holes or recesses for receiving a protrusion of the resilient coupling. By cooperating the resilient connector with either the first or second connector recess or holes, there is the advantage of providing a strong and stable releasable connection of the extractor. In this way, it is possible to prevent any unintended exit of the aerosol-generating article from the device. In addition, this arrangement allows a snap connection between the device and the extractor. In this way, the extractor can be easily connected and disconnected from the aerosol generating device, as well as providing reliable tactile and audible feedback that the extractor is fixed in place or brought into interaction with a place that is either in the first or second position. .

Preferably, the first connection recess or hole is located further from the open end of the heating jacket than the second connection recess or hole. Preferably, the second connection recess or hole is located closer to the open end of the heating jacket than the first connection recess or hole.

Preferably, the heating mantle comprises a pair of recesses or holes corresponding to each resilient connector that is provided in the extractor. For example, if there are two resilient connectors on the extractor body, the heating mantle will preferably comprise two pairs of first and second connector recesses or holes corresponding to each of the two resilient connectors. Preferably, if the heating jacket has a substantially circular cross section, then each pair of first and second connection recesses or holes corresponding to each of the two resilient connectors may be spaced at regular intervals around the circumference of the heating jacket.

Preferably, at least a portion of the elastic coupling element is configured to frictionally interact with the inner surface of the heating jacket when the extractor is moved between the first and second positions. This frictional interaction allows for an improved and more stable feel to the user as the extractor is moved between the first and second positions. In particular, such frictional interaction may mean that the extractor does not move freely between the first and second positions, and instead requires input from the user. This may mean that the extractor only moves between said positions when the user applies a driving force, and therefore there is no accidental movement (eg by gravity) between said positions.

According to a third aspect of the present invention, a mouthpiece for an aerosol generating device is provided. The mouthpiece comprises a mouthpiece casing and an extractor according to the first aspect of the present invention, the extractor being located within the mouthpiece casing. The aerosol generating device may be any aerosol generating device according to the second aspect of the present invention.

The aerosol-generating articles used in the present invention may comprise a variety of elements, including a rod of an aerosol-generating substrate. The outer wrapper may contain cigarette paper.

Aerosol generating articles typically comprise a hollow acetate tube directly adjacent to a rod of aerosol generating substrate.

The aerosol-generating substrate rod is made of an aerosol-generating material, which is particularly preferably a homogenized tobacco material.

In the context of this document, the term "homogenized tobacco material" covers any tobacco material obtained by agglomeration of particles of tobacco material. Sheets or webs of homogenized tobacco material are produced by agglomerating particulate tobacco obtained by grinding or otherwise pulverizing one or both of tobacco leaf lamellae and tobacco leaf stems. In addition, the homogenized tobacco material may contain a minor amount of one or more of tobacco dust, tobacco fines, and other particulate tobacco by-products generated during tobacco processing, handling, and shipping. Sheets of homogenized tobacco material can be made using molding, extrusion, papermaking, or any other suitable processes known in the art.

Said rod may comprise one or more sheets of homogenized tobacco material which have been assembled to form a plug and surrounded by an overwrap. Used in this document with reference to the present invention, the term "sheet" describes a flat element, the width and length of which is significantly greater than its thickness. As used herein with reference to the present invention, the term "assembled" describes a sheet that is rolled, folded, or otherwise compressed or narrowed in a direction substantially transverse to the longitudinal axis of the aerosol generating article.

Preferably, the aerosol-forming substrate comprises a rod of homogenized tobacco material surrounded by a wrapper provided around and in contact with the homogenized tobacco material.

The aerosol-generating substrate rod preferably has an outer diameter that is approximately equal to the outer diameter of the aerosol-generating article.

The aerosolizing substrate rod may have an outer diameter of from about 5 millimeters to about 12 millimeters, for example, from about 5 millimeters to about 10 millimeters, or from about 6 millimeters to about 8 millimeters.

The aerosol-forming substrate rod may have a length of from about 7 millimeters to about 15 mm.

The aerosol generating systems of the present invention comprise an aerosol generating article, as detailed above, in combination with an aerosol generating device that is configured to receive the upstream end of the aerosol generating article. The aerosol generating device comprises a heating element that is configured to heat the aerosol-forming substrate to generate an aerosol during use. Preferably, the heating element is configured to penetrate the aerosol-generating substrate upon insertion of the aerosol-generating article within the aerosol-generating device. For example, the heating element is preferably in the form of a heating blade.

The heating element is controlled during use so that it operates within a certain operating temperature range below the maximum operating temperature.

Preferably, the aerosol generating device also includes a housing, an electrical power source connected to the heating element, and a control element configured to control the supply of power from the power source to the heating element.

Suitable aerosol generating devices for use in the aerosol generating system according to the present invention are described in WO-A-2013/098405.

During operation, the aerosol-generating article comprising the aerosol-generating substrate can be completely enclosed within the aerosol-generating device. In this case, the user may puff on the mouthpiece of the aerosol generating device. Alternatively, during operation, the aerosol generating article comprising the aerosol generating substrate may be partially enclosed within the aerosol generating device. In this case, the user can puff directly on the aerosol generating article.

The aerosol generating article may have a substantially cylindrical shape. The aerosol generating article may be substantially elongated. The aerosol generating article may have a length and a circumference substantially perpendicular to the length. The aerosol-forming substrate may be substantially cylindrical in shape. The aerosol-forming substrate may also have a length and a circumference substantially perpendicular to the length. The aerosol-generating substrate may be placed in the sliding receptacle of the aerosol-generating device such that the length of the aerosol-generating substrate is substantially parallel to the direction of air flow in the aerosol-generating device.

Features described in relation to one aspect of the present invention may also be applicable to another aspect of the present invention.

in FIG. 9 shows a vertical front view of a mouthpiece according to the present invention.

in FIG. 1 shows a mouthpiece 1 according to the first embodiment of the present invention. As shown in FIG. 1 and 2, the mouthpiece 1 includes an extractor 10 for receiving an aerosol generating article (not shown) and a mouthpiece housing 30 for receiving an extractor 10. The mouthpiece 1 is adapted to be attached to a downstream portion of an aerosol generating device (not shown). Such a downstream portion in the present invention is the heating mantle 50 shown in FIG. 1, 2 and 8, made with the possibility of detachable connection with an aerosol generating device and with the possibility of placing a heater (not shown) of the device in it. Although the heating jacket 50 is shown as a separate component from the aerosol generating device, it is possible for the heating jacket 50 to be integral with the device.

As shown in FIG. 1, 2, 3a and 3b, the extractor body 20 defines a cavity for receiving an aerosol generating article. Housing 20, as shown in FIG. 1 comprises a first end 21 and an opposing second end 22, the first end 21 being open, thus forming an inlet or opening leading into the cavity of the body 20, and the second end 22 being substantially closed, thus providing a support surface for abutting the aerosol generating aerosol against it. product when placing the product inside the extractor 10.

The extractor 10 is designed to be fixedly fixed inside the casing 30 of the mouthpiece 1. As shown in FIG. 1, the mouthpiece 30 has an open end 31 also intended to receive an aerosol generating article. Inserting an aerosol generating article into the mouthpiece 1 includes inserting an aerosol generating article through the open end 31 into the cavity formed by the extractor body 20 . The aerosol-generating article is considered to be fully inserted into the mouthpiece 1 when the end of the aerosol-forming aerosol-generating substrate of the aerosol-generating article rests against the inner surface of the second, closed end 22. Due to the fixed attachment of the extractor 10 to the mouthpiece housing 30, the extractor 10 does not move relative to the mouthpiece 30 or the mouthpiece 1.

As shown in FIG. 1, 2, 3a and 3b, both extractor body 20 and heating mantle 50 comprise substantially cylindrical tubes. The extractor body 20 is somewhat smaller in diameter than the heating mantle 50 so that the extractor body 20 is able to slide or move within the heating mantle 50. The extractor body 20 is also somewhat smaller in diameter than the upstream portion of the mouthpiece 30, so that which allows the extractor 10 to be placed substantially within the mouthpiece housing 30. However, there must be sufficient clearance between the extractor 10 and the inner surface of the mouthpiece to allow the extractor 10 to move inside the heating housing 50. Such clearance also allows air to flow into the extractor 10 and through the aerosol-forming substrate to transfer the aerosol generated during heating to a user downstream of the mouthpiece 1.

In use, the heating mantle 50 will be substantially contained within the mouthpiece mantle 30. This is advantageous in that it prevents the user from making direct contact with the heating mantle 50 during use. During use, the heating mantle 50 may become too hot to be touched by the user, so the mouthpiece 30 and the heating mantle 50 also provide thermal insulation from the heater.

A heater (not shown) is supported on the inner surface of the heating jacket 50. As shown in FIG. 1 and 2, the heating jacket 50 includes an open end 51 for receiving the extractor 10 and thus the aerosol generating article placed inside the extractor 10 so that the aerosol generating article can be heated by the heater. The heater (not shown) contains a heating element extending in the longitudinal direction. The closed end 22 of the extractor body 20 includes an opening 26 shown in FIG. 3a, with the possibility of passing through which a heater is made inside the cavity formed by the extractor body 20.

As shown in FIG. 3a and 3b, the closed end 22 also includes a flange 2 3 in the form of a raised rim or ring which abuts against the inner surface of the housing 50 supporting the raised heater. The extractor body 20 also includes orienting projections 24 to allow the body 20 to be inserted and attached to the mouthpiece housing 30 in the correct orientation. The orienting protrusions 2 4 interact with corresponding recesses (not shown) located in the inner surface of the mouthpiece casing 30. Proper orientation of the extractor body 20 also means that the opening 26 will be correctly aligned with the heater when the extractor 10 is moved inside the heating casing 50.

The extractor 10 also includes two resilient connectors 25 attached to the outer surface of the extractor body 20 as shown in FIG. 2 and 3b. The resilient connectors 2 5 are designed to flex or move independently of the body 20 when the extractor 10 is inserted into the open end 51 of the heating jacket 50. As shown in FIG. 2 and 3b, the resilient connectors 25 comprise resilient arms or clips formed by a first section 251 and a second section 252 integrally connected to each other. The first section 251 extends substantially along the direction extending from the open end 21 of the extractor body 20 to the closed end 22 of the extractor body 20. Therefore, the first section 251 extends from the proximal end located closer to the open end 21 and attached to the body 20 by the second section 252, to the distal end located closer to the closed end 22 away from the body 20. The second section 252 extends from the first end, attached to the housing 20, to the second end connected to the proximal end of the first section 251 of the elastic connecting element. Therefore, between the first section 251 of the elastic coupling 25 and the body 20 of the extractor 10, there is a gap providing space for the elastic coupling to flex when it is subjected to sliding deformation inside the heating jacket 50.

As shown in FIG. 2 and 3b, the resilient connectors 25 include a lip 2 53 provided at the distal end of the first portion 251 of each resilient connector 25. The lip 253 extends from the housing 20 and is configured to engage with the connection holes 55 located along the heating jacket 50. As shown in FIG. 2, protrusion 253 is in the form of a raised, curved portion of resilient coupler 25.

The elastic connectors 25 are positioned such that the protrusion 253 is offset from the body 20 of the extractor 10 so that in the undeformed or undeflected state of the elastic connector 25 there is a gap between the first section 251 of the elastic connector 25 and the extractor body 20. In the deflected state, the first portion 251 is bent towards the body 20 of the extractor 10, as shown in FIG. 7b. Thus, the effective diameter of the extractor is 10, i.e. the diameter of the extractor 10, taking into account the elastic connecting elements 25 attached to the body 20 of the extractor 10, in the undeflected state (see Fig. 7a) is greater than the effective diameter of the extractor 10 in the deflected state (see Figs. 7a and 7c) of the elastic connecting elements 25.

As shown in FIG. 8, the heating jacket 50 includes two pairs of connection holes 55, each of which is configured to receive projections 253 of each of the elastic connection elements 25. Each pair of connection holes 55 is located in a different position in the circumferential direction on the heater 50, and each pair of connection holes holes 55 contains the first and second connecting holes 551, 552.

The first connection holes 551 are configured to releasably connect the extractor 10 to the heating jacket 50 in a first position, which is an operating position in which the heater of the aerosol generating device is capable of heating the aerosol-forming substrate of the aerosol-generating article placed inside the mouthpiece 1 and the extractor 10. In the first position, the heater passes through the opening 26 to penetrate the interior of the aerosol-forming substrate and heat it to form an inhalable aerosol for puffing by the user.

The second connection holes 552 are configured to releasably connect the extractor 10 to the heating jacket 50 in a second position, which is an extraction position, in which the heater of the aerosol generating device is at least partially removed from the aerosol generating substrate of the aerosol generating article located inside the mouthpiece 1 and the extractor 10 to assist in the removal of the article from the extractor 10. In the second position, the heater penetrates less into the aerosol-forming substrate than in the first position, which is the operating position, or does not penetrate the aerosol-forming substrate at all.

According to the respective purposes of the connection holes 551, 552, the first connection holes 551 are located farther from the open end 51 of the heating jacket 50 than the second connection holes 552.

In use, the user inserts the aerosol generating article into the mouthpiece 1 (shown in FIG. 9) with the extractor 10 in the first position so that the heater penetrates the interior of the aerosol generating article. The user activates the heater of the aerosol-generating device so that the heater heats the aerosol-generating substrate as the user puffs on the articles, thereby creating an aerosol. The heater may heat continuously after initial activation, such as being activated by the first puff performed by the user or by a user activated switch, or it may be heated only when the user puffs on the article. The resulting aerosol is carried in an air stream to the user's mouth. If the aerosol-generating article is completely consumed, or if the user has deemed the aerosol-generating article used, the extractor 10 can be moved from the first position, which is the operating position, to the second position, which is the extraction position. This can be done manually by the user by pulling the mouthpiece 1. In this case, the user can grip the mouthpiece 1 to pull the extractor 10 in a direction downstream of the heating mantle 50. The extractor 10 and therefore the mouthpiece 1 is designed to be completely separated from the heating mantle 50 if the mouthpiece 1 is further pulled towards itself while the extractor 10 is in the second position, which is the extraction position. This provides the advantage of being able to replace and clean the mouthpiece 1 and the extractor 10, as well as cleaning the heating jacket 50 and the heater contained therein.

On FIG. 7a, 7b and 7c show how the resilient connector 25 is configured to engage with the second connector hole 552 when the extractor 10 is inserted into the heating jacket 50 or when reinserted after the mouthpiece 1 is removed from the aerosol generating device. The protrusion 253 includes a first sloping surface 254 oriented towards the first, open end 21 of the extractor body 20, and a second sloping surface 255 oriented towards the second, closed end 21 of the extractor body 20.

The effective diameter of the extractor 10, defined by the largest distance between the two opposing resilient connectors 25, is greater than the inner diameter defined by the heating jacket 50. Thus, when the extractor 10 is inserted into the heating jacket 50, the second inclined surfaces 255 of the two resilient connectors 25 enter into contact with the inner edge of the wall of the heating mantle forming the open end 51. The slope of the second ramp 255 is substantially gentle such that further advancement or sliding of the extractor 10 upstream into the heating mantle 50 presses the second ramp 255 against the inner edge of the open end 51 , which forces the resilient coupling 25 to compress and deviate towards the body 20 of the extractor 10. Deflection of the resilient coupling 25 towards the body 20 of the extractor 10, as shown in FIG. 7b allows the extractor to frictionally interact with the inside of the heating jacket 50. As the extractor 10 further slides inside the heating jacket 50, the protrusion 253 will meet the second connection hole 552 at a distance from the inside edge of the open end 51. the protrusion 253 move away from the extractor body 20 to releasably engage with the second connecting hole 552, resulting in the extractor 10 being placed in the second position,

representing the extraction position. The lug 253 effectively snaps into the second connection hole 552. This is useful because the snapping is capable of providing a tactile and audible indication to the user that the extractor 10 has been successfully locked into the second position, which is the extraction position.

Further sliding of the extractor 10 against the flow along the heating jacket 50 enables the second inclined surface 255 to be pressed against the upstream inner edge of the second opening 552, which, as in the previous example, forces the resilient connecting element 25 to deviate in the direction of the body 20 of the extractor 10. Due to deflection of the elastic coupling 25 towards the body 20 of the extractor 10, similar to that shown in FIG. 7b, the extractor is allowed to frictionally interact with the inside of the heating jacket 50 at any location between the first connection hole 551 and the second connection hole 552. orifice 552 and further away from the inner edge of the open end 51. The compressed or resilient nature of the resilient connector 25 will force the protrusion 253 out of the housing 20 to releasably engage with the first connector hole 551, thereby locking the extractor 10 in the first position, which is the operating position. . The protrusion 253 effectively snaps into the first connection hole 552. This is useful because it provides a tactile and audible indication to the user that the extractor 10 has been successfully locked into the first position, which is the operating position.

When the extractor 10 is in the first position, which is the operating position, the user is able to insert the aerosol generating article inside the extractor 10 so as to allow the article to be heated and puffed on. In some embodiments, further advancement or sliding of the extractor 10 beyond its operating position within the heating jacket 50 will not be allowed due to the abutment of the closed end 22 and flange 23 of the extractor body 20 against the inner surface on which the heater is supported within the heating jacket 50. However, due to the interaction of the resilient connecting member 25 with the first connection hole 551, ensures that the extractor 10 is firmly connected to the heater body 50 during operation of the aerosol generating device, and also ensures that only a deliberate action results in the release of the extractor 10 from said interaction.

As shown in FIG. 7a, 7b and 7c, the second ramp 255 has a gentler slope than the first ramp 254 to ensure that the force required to translate the extractor 10 further inside the heating jacket 50 is less than that required to draw extractor from a second position representing the extraction position. It also ensures that a higher intentional force is required by the user to fully withdraw the extractor 10 from the heating jacket 50 or to move the extractor 10 from the first position to the second position. In other words, fixing the extractor 10 in the first and second positions is made easier, that is, requiring less force than releasing the extractor 10 from said first and second positions.

Sliding the extractor 10 from the first position, which is the operating position, to the second position, which is the position of withdrawing or completely withdrawing the extractor 10 from the heating jacket 50, includes a process similar to the above-described interaction process. However, such disengagement movements will require force to be applied in a direction downstream of the heater, rather than upstream of the heater as described above, which includes inserting the extractor 10 into the heating mantle 50 and advancing it from the second opening 552 to the first opening 551. The main difference is that the first inclined surface 2 54 will be pressed against the respective downstream inner edges of the first and second connecting holes 551 and 552 in order to deflect the elastic connecting element 25 towards the body 20 of the extractor 10 and enable the sliding of the extractor 10 downstream of the heating mantle 50. As described above, since the first ramp 254 has a less gentle slope than the second ramp 255, the force required to push the extractor 10 downstream of the heater is greater than the force necessary to push the extractor 10 against the flow to the heater.

On FIG. 4, 5, 6a and 6b show an alternative second embodiment of the mouthpiece 1' and the extractor 10', which differs from the first embodiment mainly in that the elastic connectors 25' attached to the extractor 10' of the second embodiment are shorter. than the elements of the first embodiment. In the first embodiment, the length of the elastic connecting elements 2 5 is equal to the length of the extractor body 20 or is at least 50% to 100% of this length. In the second embodiment, the length of the elastic connecting elements 25' is less than at least 50% of the length of the extractor body 20'. All other features described above with respect to the first embodiment are presented in the same form in the second embodiment. For this reason, features of the second embodiment for which reference numbers have been omitted can be considered essentially the same as those described with respect to the first embodiment shown in FIG. 1, 2, 3a and 3b. The heating jacket 50 to which the mouthpiece 1' is connected is essentially the same as those described above and below.

On FIG. 8 shows the downstream end of the heating mantle 50. The heating mantle 50 has a projecting track 53 extending longitudinally along the inner surface of the heating mantle 50. The track 53 is adapted to cooperate with a groove or groove (not shown) located in the outer surface of the casing. 20 extractors. The interaction of the guide track 53 with such a corresponding slot in the extractor body 20 ensures that the extractor body 20 does not rotate or move when positioned or slid within the heating mantle 50.

On FIG. 9 shows a mouthpiece 1 according to the present invention. The mouthpiece housing 30 includes an extractor 10 according to any of the first and second embodiments of the present invention described in detail above.
