Description

Aerosol-generating device comprising a holding element

The present invention relates to an aerosol generating device.

The aerosol-generating device allows aerosolization of the aerosolizable material. Aerosol generating devices may also be referred to as electronic cigarettes or vapor generating devices.

Aerosol-generating or heat-not-burn devices typically include a battery-operated vapor-generating unit that generates an aerosol that is inhaled. This type of device generates an aerosol or vapor by heating an aerosol substrate, typically moist tobacco leaves or other suitable aerosol, to a temperature typically in the range of 150°C to 300°C. Solified material.

In such devices, the aerosol matrix is typically contained within a consumable that is held within a heating chamber and heated by a heater. Most commonly, such heated chambers are heated from the outside, while a heat-conducting shell-like housing transfers the heat to the inner volume. Heaters are typically arranged along the length of the heating chamber.

One problem with prior art devices is the difficulty in removing consumables from the heating chamber at the end of use. The bottom portion of the consumable typically remains in the heating chamber and is difficult to remove by the user.

While there are aerosol generating devices that solve other problems, such as the device disclosed in KR 102051205 aimed at improving the fixation of consumables, existing devices cannot easily remove the consumables from the heating chamber.

It is therefore an object of the present invention to be able to easily eject consumables from the heating chamber when required.

The invention thus relates to an aerosol-generating device comprising: a heating chamber arranged to receive a consumable; a heater configured to heat the consumable to release an aerosol.

According to the invention, the aerosol-generating device further comprises a gripping element configured to grip the consumable and eject the consumable from the heating chamber when required.

Thanks to the clamping element, the consumable can be easily ejected when required, for example at the end of its use.

This improves the user's experience, and consumables can be easily replaced when needed.

According to one embodiment, the clamping element is a jaw device comprising a drive member and jaws attached to said drive member, said drive member being configured to move the jaws inwards such that The jaws are brought closer to each other, and the jaws are moved outwardly to move the jaws away from each other.

According to one embodiment, the drive member is a telescopic tube configured to extend to move the jaws outwards and to shorten to move the jaws inwards.

The clamping element can thus be a claw device that is simple to manufacture and handle.

According to one embodiment, each jaw is hinged on the drive member at a first point and at a second point different from the first point, each jaw being hinged at said first point to the The telescoping cylinder, and hinged at said second point by a ring attached to the end of the telescoping cylinder, said ring being configured to move in the telescoping direction of the telescoping cylinder.

According to one embodiment, the telescoping barrel is configured to extend when the consumable is ejected, thereby moving the jaws outwards and bringing the ring against the consumable.

The ring thus makes it possible to push the consumables out of the heating chamber.

According to one embodiment, the telescopic barrel is configured to shorten during heating of the consumable, thereby moving the jaws inwardly and keeping the ring away from the consumable.

Depending on how far the barrel is shortened, the jaws can simply grip the consumable or apply enough force to compress the consumable.

According to one embodiment, the telescoping barrel is configured to extend at the end of heating of the consumable, thereby causing the arms to move outwards to release the consumable.

According to one embodiment, the aerosol-generating device further comprises a microcontroller configured to activate the The drive member moves automatically.

Thus, the gripping element is operated automatically by the microcontroller depending on whether the session of smoking has started, is in progress or ended.

According to one embodiment, the aerosol-generating device comprises a housing within which the heating chamber, the heater and the clamping element extend, the housing comprising a through-hole through which the drive member extends, For example a part of the drive member protrudes from the housing.

The clamping element can be easily manipulated by moving the drive member manually, in particular using a protrusion.

According to one embodiment, the aerosol-generating device comprises a housing within which the heating chamber, the heater and the clamping element extend, wherein the aerosol-generating device further comprises a A slider fitted to the drive member of the clamping element such that the drive member is driven by movement of the slider.

Sliders are an alternative solution to manually actuated clamping elements. Like protrusions, slides are easy to use and simple to manufacture.

According to one embodiment, the heater and the clamping element are positioned relative to each other such that the jaws are heated conductively by the heater, the clamping element being configured to compress the consumable when heated. consumables.

Compressing the consumable strains key features during use of the consumable, as this concentrates heat into the center of the consumable, allowing for faster warm-up times. This is achieved by conduction heating of the jaws. Furthermore, since the consumable contracts as it is pumped, the compaction maintains high heat transfer throughout the life of the consumable, thus maintaining good heating efficiency.

According to one embodiment, the clamping element is configured to stop compressing the consumable when the heating stops.

The configuration of the device is particularly advantageous in that it compresses the consumable during use for optimal heating, but stops compressing the consumable when required, such as when the consumable needs to be replaced. This avoids unnecessary compression and possible friction between the clamping element and the consumable or between the heating chamber and the consumable due to the compression. In fact, when manipulating consumables, these frictions need to be overcome, causing the consumables to deteriorate. Such friction can, for example, make it difficult to remove the consumable from the heating chamber.

In summary, the configuration of the aerosol generating device with the clamping element ensures fast and efficient heating of the consumable while enabling easy ejection of the consumable from the heating chamber when required.

According to one embodiment, the heater comprises a resistive heating element fitted on the jaws of the clamping element.

Thanks to this configuration, the heating of the consumables is improved. In fact, during the heating process, the jaws are in direct contact with the consumable.

According to one embodiment, the heater comprises a fixed heater extending on the wall of the heating chamber.

Conductive heating of consumables is thus possible. This is a simple and efficient solution for heating consumables to convert them into aerosols.

Preferably, the heater extends along the entire length of said wall of the heating chamber. This provides a larger heating area enabling the consumable to be heated quickly.

According to one embodiment, the heating chamber comprises slots shaped to receive the clamping element configured to move within the slots to compress or release the consumable.

As used herein, the terms " aerosol " and " vapour " are used interchangeably to refer to a suspension of particles or droplets of any size. Similarly, the term " vaporization " means to change or cause to change into a vapor, and the term " aerosolization " means to form and/or disperse into an aerosol.

An example aerosol-generating device 1 is shown in FIG. 1 . The aerosol-generating device 1 comprises an outer housing 2 having a bottom part and a top part. The top part of the housing 2 is provided with an aperture 20 through which an aerosol-generating consumable can be inserted.

Inside the housing 2, the aerosol-generating device 1 comprises a heating assembly 3, a printed circuit board or PCB 4, and a battery 5, visible in FIG. FIG. 2 shows a schematic cross-sectional view of the aerosol-generating device 1 . For clarity, some components have been omitted from Figures 1 and 2 .

The battery 5 or power supply unit is adapted to power the electronic components of the device.

The heating assembly 3 is operatively connected to the PCB 4 and the battery 5 . The heating element 3 is selectively powered to heat it to a controlled temperature.

The heating assembly 3 comprises a heater 30 and a tubular heating chamber 31 with an opening 310 . In this example, the opening 310 is provided by the open end of the heating chamber 31 . In an alternative example of the arrangement, the opening 310 may be arranged elsewhere on the heating chamber 31 .

The tubular heating chamber 31 includes a closed end 311 opposite the opening 310 , and a side wall 312 extending between the opening 310 and the closed end 311 to define an interior volume of the heating chamber 31 . The opening 310 is aligned with the aperture 20 so that the inner volume of the heating chamber 31 can be accessed through the aperture 20 and the opening 310 when the device 1 is fully assembled.

The heating chamber 31 is configured to receive consumables 6 . The consumables 6 are inserted through the aperture 20 of the housing 2 and the opening 310 of the heating chamber 31 .

The consumable 6 comprises an aerosol base adapted to transform into an aerosol when heated.

The aerosol base may include, for example, tobacco in dried or cured form, in some cases with additional ingredients for flavoring or to create a smoother or otherwise more pleasurable experience. In some examples, an aerosol substrate, such as tobacco, may be treated with a vaporizing agent. Vaporizing agents can improve vapor generation from an aerosol substrate. For example, the vaporizing agent may include polyols (eg, glycerol) or glycols (eg, propylene glycol). In some cases, the aerosol base may be tobacco-free or even nicotine-free, but may contain natural or artificially derived ingredients for flavoring, volatilization, improved smoothness, and/or to provide other pleasurable effects. The aerosol matrix may be provided as a solid or paste-type material in shredded, pelleted, powdered, granular, stick or tablet form, combinations thereof as desired. Likewise, the aerosol base can be a liquid or a gel. In fact, some examples may include both solid and liquid/gel portions.

The heater 30 is configured to heat the heating chamber 31 to a temperature sufficient for the aerosol matrix to release the aerosol without burning the consumable 6 . In particular, the heater is configured to heat the aerosol substrate to a maximum temperature of between 150°C and 350°C.

The heater 30 may be any type of heater known in the prior art and capable of heating the heating chamber 31 .

The heater 30 is, for example, a fixed heater extending on the side wall 312 of the heating chamber 31 .

The heater 30 may be, for example, a thin film heater wound on the heating chamber 31 . The thin film heater is configured to provide heat to the interior volume of the heating chamber 31 . In particular, a thin film heater may be wrapped around the outer surface of the heating chamber 31 to heat the side walls 312 and the interior volume of the chamber 10 .

A thin film heater may comprise a thin film circuit with a resistive heating element. The electrical circuit comprising the heating element is arranged to increase the surface area coverage of the heating element on the wound surface of the chamber 10 .

Arranging the heater 30 around the outer surface of the heating chamber 31 allows heating of the consumable 6 while protecting the heater 30 from damage due to contact with the consumable 6 .

The side walls 312 of the heating chamber 31 preferably comprise a thermally conductive material, such as metal, to conduct heat from the heater 30 to the chamber 10 .

Although the example device 1 shown in FIG. 2 includes the heater 30 extending around the outer surface of the heating chamber 31 , in another example, the heater 30 may be disposed inside the heating chamber 31 .

Arranging the heater 30 in this manner may provide more efficient heating of the consumable since the heater 30 may directly heat the interior volume of the heating chamber 31 , thereby reducing energy lost by conduction to the side walls 312 .

Preferably, the heating chamber 31 includes insulating material to reduce heat loss.

In use, a user holds the device 1 by the housing 2 and places a smokeable aerosol-generating consumable through the aperture 20 in or near the heating element 3 of the device 1 . The device 1 is then operated by a switch or by a user's pumping action to turn on the power supply from the battery 5 to the heating element 3 in order to heat the consumables at or near the heating element 3 . The heat generated at the heating element 3 causes the consumable to heat up and release aerosol-forming vapors. The user can then inhale the aerosol.

According to one embodiment of the invention, the aerosol-generating device 1 further comprises a clamping element 7 visible in FIG. 2 and presented separately in FIG. 3 .

As can be seen in FIG. 2 , the clamping element 7 is configured to clamp the consumable 6 .

The clamping element 7 is a claw device. The clamping element 7 comprises a drive member 70 and a jaw 71 . The jaw 71 is attached to the drive member 70 .

The drive member 70 is configured to drive the jaw 71 . In particular and as can be seen in FIG. 3 , the drive member 70 is configured to move the jaws 71 inwardly, bringing them closer to each other, and outwardly, moving the jaws 71 away from each other.

The drive member 70 is a telescopic cylinder, ie a cylinder whose length can be changed. In other words, the drive member 70 is configured to extend and retract. For example, the drive member 70 includes an outer cylinder and an inner cylinder slidably engaged within the outer cylinder.

The drive member 70 has a fully extended position in which the drive member 70 is at its maximum length and a fully retracted position in which the drive member 70 is at its minimum length.

In the extended position, preferably when it is at its maximum length, the drive member 70 is configured to push the consumable 6 . This enables the consumables 6 to be ejected from the heating chamber 31 .

In the embodiment presented in FIG. 2 , the jaws 71 are substantially orthogonal to the ring 73 . The jaws 71 are substantially parallel to the consumable 6 .

The jaws 71 are made of thermally conductive material. The jaws 71 are in direct or indirect contact with the heater 30, so that the jaws 71 are heated by conduction.

In particular, if the heater 30 extends over the side wall 312 of the heating chamber 31, the jaws 71 are heated by conduction because they are in contact or flush with the heating chamber 31, which in turn is heated by the heater 30. is heated. If the heater 30 extends within the heating chamber 31 , the jaws 71 are in direct contact with the heater 30 and thus subject to direct conduction heating of the jaws.

In the example presented in FIG. 3 , each jaw 71 is hinged to the drive member 70 at a first point P1 and a second point P2 different from the first point P1 .

Each jaw 71 is hinged to the telescoping cylinder 70 at a first point P1 via a link 72 .

Each jaw 71 is articulated at a second point P2 by means of a ring 73 attached to the end 700 of the telescoping cylinder.

The ring 73 is configured to move in the telescoping direction of the telescoping cylinder. In other words, the ring 73 is configured to translate along the longitudinal axis A0 of the drive member 70 .

Translation of the ring 73 together with the linkage 72 causes the jaws 71 to move inwardly and outwardly.

When the drive member 70 is extended, the jaws 71 move outwards and the ring 73 rests on the consumable 6 (visible in Figure 6a). In the specifically presented example, moving outwards means moving away from the longitudinal axis A0 of the drive member 70 .

When the drive member 70 shortens, the jaws 71 move inwards and the ring moves away from the consumable 6 (visible in Figure 6b). In the specifically presented example, inward movement means towards the longitudinal axis A0 of the drive member 70 .

The heating chamber comprises slots 313 shaped to receive the clamping element 7 (visible in FIG. 4 ).

In particular, the slot 313 is shaped and sized such that the jaw 71 can move within the slot 313 . Preferably, the shape of the slot 313 is similar to that of the jaw 71 . The size of the slot 313 is larger than that of the jaw 71 so that the jaw 71 can move inwardly and outwardly within the slot 313 .

The number of slots 313 is equal to the number of jaws 71 of the clamping element 7 .

In the example presented, the heating chamber 31 comprises four slots 313 extending longitudinally and relative to each other in a rectangular array. A rectangular array means that the four slots 313 extend around the longitudinal axis of the heating chamber 31 at 90° relative to each other. The clamping element 7 similarly comprises four jaws 71 extending relative to each other in a rectangular array, or in other words at 90° relative to each other around the longitudinal axis A0 of the drive member 70 .

In an example embodiment, the aerosol-generating device further includes a microcontroller 40 . A microcontroller 40 is mounted on the PCB 4 . The microcontroller is configured to automatically move the drive member 70 . In particular, the microcontroller is configured to automatically extend and retract the drive member 70 .

In another embodiment, the clamping element 7 can be operated manually. An example is shown in FIG. 5 a , the housing of the aerosol-generating device comprising a through hole 21 . The drive member 70 extends through the through hole 21 of the housing, eg a part of the drive member 70 protrudes from the housing. The user can thus move the drive member 70 by pulling or pushing the protruding portion 701 of the drive member 70 .

In particular, when the protruding portion 701 is pulled, the drive member 70 shortens. When the protruding portion 701 is pushed, the driving member protrudes.

In another embodiment of the manual operation of the gripping element 7 presented in Fig. 5b, the aerosol generating device may comprise a slide 23 extending on the outer wall of the housing. The slide 23 may be mounted to a drive member 70 of the clamping element 7 such that the drive member 70 is driven by the movement of the slide.

In the embodiment presented in FIG. 5 b , the slider extends along the wall 22 parallel to the drive member 70 and is configured to slide on said wall 22 . The slider 23 is mounted to the drive member 70 such that translation of the slider 23 causes translation of the drive member. In particular, the drive member 70 shortens when the slider 23 moves along the wall 22 away from the aperture 20 of the housing 2 . When the slider 23 is moved along the wall 22 towards the aperture 20, the drive member 70 is extended.

Embodiments of automatic and manual operation of the clamping element 7 can be combined. For example, the aerosol-generating device may include the microcontroller 40 , the protruding portion 701 of the drive member 70 , and/or the slider 23 .

The gripping element 7 is configured to eject consumables from the heating chamber when required. This is desired, for example, at the end of use of the consumable.

In the embodiment presented, in order to eject the consumable 6 , the drive member 70 is extended such that the ring 73 rests on the consumable 6 . Then, the ring 73 pushes the consumable 6 under the action of the drive member 70 . At least a part of the consumable 6 is thus pushed out of the heating chamber 31 . Since the jaws 71 move outwards when the drive member 70 is extended, the user can remove the consumable 6 from the heating chamber 31 . The consumables are pushed out of the heating chamber through the opening 310 of the heating chamber 31 and the orifice 20 of the housing 2 .

The clamping element 7 is also configured to compress the consumable when it is heated. To this end, the jaws 71 are moved inwards to be able to exert a certain force on the consumable. In the embodiment presented, the drive member 70 is shortened, thereby moving the jaws 71 inwardly.

Compression helps to concentrate heat into the center of the consumable, which allows for faster heating of the consumable. In fact, thanks to the conductive heating of the jaws 71 by the heater 30 , said jaws 71 are thus in turn able to heat the consumable 6 .

If the heater extends externally along the wall of the heating chamber, the jaws 71 can first be heated when the clamping element 7 is in the open position and thus are in contact or flush with the heated side wall 312 of the heating chamber 31 . Once the clamping element 7 has been brought into the closed position, the jaws 71 are heated and thus enhance the heating of the consumable 6 during its compression.

If a heater extends inside the heating chamber, the jaws 71 may be in direct contact with said heater. Jaws 71 that are heated when compressing the consumable can similarly enhance heating of the consumable.

In all cases, compacting the consumables maintains high heat transfer and good efficiency in heating the consumables.

The more contact surfaces the jaws 71 have with important consumables, the more efficient the compaction. Each jaw 71 may have a flat wall configured to contact the consumable 6 as the jaw moves inwardly. The flat wall may extend over the entire length of the jaw 71 , as is the case in the presented embodiment of FIG. 2 .

Compression of the consumable refers to the application of more force than is required to grip the consumable. Compression of the consumable typically leaves indentations on the consumable where force is applied.

In the embodiment presented, the compression of the consumable 6 is effected by the jaws 71 of the clamping element 7 . Of course, the clamping element 7 could be configured to compress the consumable 6 in other ways. The clamping element 7 may for example comprise a crossbar for pressing the consumable 6 .

When the heating stops, the clamping element 7 stops compressing the consumable.

Figures 6 and 7 show the clamping element 7 in an open position and in a closed position. In particular, Figures 6a and 7a show the clamping element 7 in the open position, ie in a position where the consumable 6 is released. Figures 6b and 7b show the clamping element 7 in the closed position, ie in the position where the consumable 6 is pressed. As can be seen in these figures, the jaws 71 slide through the slots 313 of the heating chamber 31 to move from the closed position to the open position and vice versa.

In the example presented, the telescoping barrel shortens during heating of the consumable. The telescoping barrel extends at the end of the consumable heating, causing the arms to move outward to release the consumable and eventually pop out to eject the consumable. The clamping element 7 is configured to move within the slot 313 of the heating chamber to compress, release or eject the consumable.

In embodiments using a microcontroller, the microcontroller is configured to automatically move the drive member 70 based on whether the consumable is being heated, stopped heating it, or ejected from the heating chamber. Therefore, the user does not need to take any action other than using the aerosol-generating device as usual.

In an embodiment, the heater 30 may comprise a resistive heating element 300 fitted on the jaws 71 of the clamping element 7 (visible in Figs. 6a, 6b). The resistive heating element 300 may be used in combination with a primary heater such as those described above. Combined with the ability to conductively heat the jaws 71 by the primary heater 30 , the resistive element 300 increases the heating efficiency of the consumable 6 even more.

It should be understood that various changes and modifications to the presently preferred embodiment described herein will be apparent to those skilled in the art. Such changes and modifications can be made without departing from the spirit and scope of the invention and without diminishing its attendant advantages. Accordingly, such changes and modifications are intended to be covered by the appended claims.

The present invention thus provides an aerosol-generating device with a gripping element that is advantageously configured such as to be able to eject the consumable when required, thereby enabling the user to easily replace the consumable. The clamping element further improves the heating of the consumables.
