Description

Middle-segment particle type aerosol generating product and combined set comprising same

Technical Field

The present invention is in the field of aerosol-generating articles, in particular aerosol-generating articles using particles of aerosol-source material, and more particularly relates to a mid-particle aerosol-generating article and a kit comprising the same.

Background

Particle-type aerosol-generating articles are a new type of Heat-Not-Burn (abbreviated as HNB) aerosol-generating articles in recent years, which use aerosol-source material particles as an aerosol-generating material instead of an aerosol-source material sheet, the aerosol-source material particles are heated more uniformly than the aerosol-source material sheet, and the aerosol spreads more smoothly along inter-particle gaps than along sheet-like material gaps, and thus are popular among consumers.

Particulate aerosol-generating articles are known products on the market, the structure of which is illustrated with reference to figure 1: the main structure of the aerosol source material cigarette is an integrated outer sleeve X1, the far lip end of the integrated outer sleeve is sealed by a sealing film X2, then aerosol source material particles X3 are filled into the integrated outer sleeve to form a particle section, a multi-hole fixing section (commonly called a gear piece) X4 is arranged at the downstream of the particle section, then an airflow channel section X5 is reserved for collecting and containing aerosol (sometimes the airflow channel section X5 is a single section of cavity, or sometimes the airflow channel section X5 is a hollow rod), and a filter section X6 is arranged at the downstream of the airflow channel section X5 and is used as a cigarette holder for holding in the mouth of a user. The aerosol-generating article is in use inserted with the distal lip end into a heating device having a heating element for heating particles of aerosol source material to release gaseous flavour components which condense into a macroscopic aerosol on exposure to cold air in the airflow passage segment X5, which aerosol then passes through the filter segment and into the mouth of a user.

The airflow channel segment X5 is crucial for aerosol formation, and according to the theory of aerosol science, the gaseous flavor component released by heating needs to be cooled to be condensed into solid particles or liquid particles, and the solid particles or liquid particles need to be suspended in the air to form aerosol (commonly called "smoke" or "fog" or "smoke" in general) visible to the naked eye. Therefore, in existing particle-type aerosol-generating articles, the airflow channel segment X5 must be left.

Furthermore, because the particles are loose and fluid, if not constrained, they inevitably flow on a large scale to the downstream airflow path segment X5 when the aerosol-generating article is placed horizontally or inverted, resulting in a substantial reduction in the number of particles that can be directly heated by the heating element, and naturally the amount of flavour released and subsequently generated aerosol will also be reduced, and to ensure that the particles are sufficiently heated, the particles must be constrained within a limited space in the vicinity of the heating element. The constraint is realized by arranging a sealing film X2 at the upstream of the granule section and providing a multi-hole fastener section X4 at the downstream of the granule section, and the two ends are constrained so that the granules cannot flow everywhere.

The sealing film X2 is usually high-permeability thin paper and then is adhered to the upstream end face of the outer sleeve X1 by an adhesion method, and the adhering process of the sealing film X2 is complex in process and low in efficiency, and special sealing film adhering equipment is needed. In addition, because the end surface of the outer sleeve X1 is not on the same plane, burrs and the like exist, the surface of the thin paper has defects, the gluing is not uniform and the like, the sealing film is not firmly adhered, the sealing film for sealing the opening of the aerosol generating product is degummed in the subsequent production process, the leakage of the internal storage granular material is caused, the production environment is polluted, certain other materials are lost, and the production efficiency is influenced. The existing granular heating cigarette is manufactured by adopting a mode of sealing by a sealing film and filling granules. The problems of low automation degree, low sealing success rate (and difficult detection) and low production efficiency of aerosol generating products exist. When used, the sealing film is pierced and heated, and particles are scattered out of the aerosol-generating device after the aerosol-generating product is pulled out of the aerosol-generating device, which makes it difficult to clean the aerosol-generating device.

Wherein the multi-porous anchoring section X4 is generally made of ceramic or silica gel, the outer wall of which is firmly affixed to the inner wall of the paper sleeve by means of an adhesive, and which has at least one axial through hole X41 in its centre and/or at least one peripheral ventilation groove X42 in its periphery, which are dimensioned to allow the passage of the fumes but not the passage of the particles of the aerosol source material, both to block them and to transmit them. However, the presence of the multi-aperture fastener segment adds cost and operational inconvenience to the commercial manufacture of particulate aerosol-generating articles and it is therefore a continuing desire of those skilled in the art to eliminate the multi-aperture fastener segment. However, eliminating the multi-ported fastener segment necessitates the placement of a gas flow channel segment downstream of the particle segment to collect and contain the aerosol, and this segment also serves to confine the aerosol source material particles that are scattered, presenting a dilemma.

In addition, the aerosol-source material particles of the existing particle-type aerosol-generating articles are located most upstream of the aerosol-generating article (the end face is separated from the outside only by a thin sealing film), and are easily affected by the outside during transportation and storage. In addition, in order to ensure that the aerosol source material particles are more easily heated to generate aerosol when being sucked and that the generated aerosol can be better released, the aerosol source material particles need to be packed as loose as possible and not to be particularly compact. However, this results in a large contact area of the aerosol source material particles with the air during transportation and storage, which leads to a loss of the added additives such as flavors or smoking agents within the aerosol source material particles.

Therefore, it is an urgent need to solve the problem of eliminating the sealing film and the multi-vent fixture section, restraining the scattered aerosol source material particles, ensuring that the generated aerosol can be smoothly delivered to the filter section, and preventing the aerosol source material particles from being located at the most upstream of the aerosol generating product during transportation and storage.

The present invention is directed to solving the above problems.

Disclosure of Invention

The present invention provides a mid-stream particle type aerosol-generating article comprising an outer tube 5, and a filter part 1, an aerosol-source material particle part 2 and a seizing part 3 which are located within the outer tube 5 and arranged in this order from a proximal lip end to a distal lip end;

the aerosol-source-material particle part 2 has an upstream end face which is axially spaced from the upstream end face of the particulate aerosol-generating article by a distance which forms an end cavity 4 by the outer tube 5, and the capture part 3 is located in the end cavity 4 and is axially movable in the end cavity 4.

The upstream and downstream referred to in the present invention are defined in terms of the gas flow direction. More specifically, the distal labial end is upstream and the proximal labial end is downstream.

The sequential arrangement in the invention is not limited to the tight connection of the two, but only the order. That is, other forms of units may be interposed between any two of the filter section 1, the aerosol source material particle section 2 and the capture section 3.

Preferably, the entrapment part 3 is located at a downstream end of the end cavity 4 when the particulate aerosol-generating article is in a non-smoking state position, and the section 2 of aerosol-source material particles contains aerosol-source material particles 21;

the entrapment part 3 is located at the upstream end of the end cavity 4 when the particulate aerosol-generating article is in a position of a suction state, aerosol source material particles 21 contained in the aerosol source material particle part 2 drop into the end cavity 4, and an area of the aerosol source material particle part 2 containing the aerosol source material particles 21 forms an airflow channel 22.

That is, the particulate aerosol-generating article of the invention has two positions for the aerosol source material particles and the capture member 3, both in the non-drawn state, in which the aerosol source material particles are located in the midsection of the aerosol-generating article and the capture member 3 is also located furthest downstream of the end cavity 4 to block off the downstream aerosol source material particles, and in the drawn state. When in the suction state, the entrapment part 3 is pulled down and moved to the most upstream side of the end cavity 4 (the upstream end face of the entrapment part 3 is flush with the upstream end face of the end cavity 4), and the aerosol source material particles fall into the end cavity along with the pulling-down process of the entrapment part 3, but the upstream end face is still occluded by the entrapment part 3.

Therefore, the aerosol source material particles are positioned in the middle section in the transportation and storage process, the two ends of the aerosol source material particles are blocked by the filtering part 1 and the blocking part 3, and further, if the aerosol source material particles are filled into the hollow part, the aerosol source material particles can be filled more tightly, the contact area with air is minimum, and therefore the additives such as essence, spice or smoke agent and the like added into the aerosol source material particles are better preserved. While the aerosol source material particles fall into the end cavity as the sealing part 3 moves during use, the particles fall into the end cavity 4 and are relatively loose due to the larger diameter of the end cavity relative to the diameter of the hollow cavity of the hollow part, which is beneficial to the generation and release of the aerosol. Heating of the aerosol source material particles to produce a smokable aerosol can be accomplished using the heating element of a conventional aerosol-generating appliance, while an airflow channel is formed where the aerosol source material particles were originally contained to provide space for the flow and convergence of the aerosol.

Preferably, the snap-seal part 3 has a protrusion 33 thereon, and the snap-seal part 3 is controlled to move axially in the end cavity 4 by the protrusion 33. The protrusion 33 may be located at any position of the sealing member 3, and may be easily pulled, and the pulling may be performed by the aerosol generating device or manually before the use of the suction device. It is of course more preferred to use the aerosol-generating device of the invention mentioned subsequently to accomplish the pulling action.

The clamping and sealing part 3 is a truncated cone-shaped hollow structure, and has a top surface 31 and an opening 32 at the bottom surface. Because the clamping and sealing part 3 is in a circular truncated cone shape, the diameter of the bottom surface of the clamping and sealing part is larger than that of the top surface, and because the clamping and sealing part does not have the bottom surface (the bottom is open), one side of the side surface close to the bottom surface is not restrained by the bottom surface and can naturally expand towards two sides, so that the friction force at the contact part of the clamping and sealing part 4 and the inner wall of the outer tube 5 is improved, and the clamping and sealing part 3 is more firm in the outer tube 5.

More preferably, the protrusion 33 is located on the bottom surface of the sealing member 3, and the locking member of the aerosol generating device used therewith enters through the opening 32 and matches with the protrusion 33.

The intermediate particle type aerosol-generating article of the present invention is not limited to the manufacturing process, and may be in a form of filling, in which the respective members are sequentially filled into the outer tube 5, or in a form of composite wrapping, in which the respective units are sequentially arranged and then the outer tube 5 is formed by wrapping and rolling. The material of the outer tube 5 is selected from, but not limited to, paper, ceramic, temperature resistant resin or clay.

The other end of the aerosol generating product directly selects the clamping and sealing part 3 to restrain aerosol source material particles, the clamping and sealing part 3 can be directly arranged in the outer tube 5 in a filling or composite mode, equipment for adhering a sealing film is not needed, and the problems that the sealing film is not firmly adhered and falls off are avoided. In addition, because the clamping and sealing part 3 is in a circular truncated cone shape, the diameter of the bottom surface of the clamping and sealing part is larger than that of the top surface, and because the bottom of the clamping and sealing part is not opened, one side of the side surface, which is close to the bottom surface, is not restrained by the bottom surface and can naturally expand towards two sides, so that the friction force at the contact part of the clamping and sealing part 4 and the inner wall of the outer tube 5 is improved, and the clamping and sealing part 3 is more firm in the outer tube 5.

Preferably, the clamping and sealing component 3 further comprises a sleeve 34, and the sleeve 34 is located outside the truncated cone-shaped hollow structure and inside the end cavity 4. Preferably, the axial length of the sleeve 34 is equal to the axial length of the end cavity 4. Preferably, the axial length of the sleeve 34 is equal to the axial length of the end cavity 4. The sleeve 34 may facilitate filling or priming of the snap seal element 3 and also facilitates defining the axial length of the end cavity 4.

Preferably, the aerosol-source material particle section 2 comprises a hollow section 23, and the hollow cavity of the hollow section 23 contains the aerosol-source material particles 21.

That is, the hollow member 23 is a hollow rod having a hollow structure, such as a hollow acetate fiber rod, a hollow corrugated grooved rod, a hollow tube having a gear structure, or a hollow paper tube, and contains the aerosol-source-material particles 21 in the hollow region. The construction of the hollow corrugated grooved rod and the hollow tube with a gear structure can be referred to a patent application with application number 2021226872810 filed by the present applicant and entitled filled aerosol generating article with a stopper, and the description of the technical solutions and effects of the hollow corrugated grooved rod and the hollow tube with a gear structure in the patent application is applicable to the present invention.

The part 2 of aerosol source material particles is one or more sections, that is to say can be one or more sections of hollow parts 23. More preferably, the aerosol source material particle section 2 comprises a multi-segment hollow section 23. Preferably two sections of hollow members of different materials. More preferably, as shown in the embodiment, the hollow member 23 near the upstream is a hollow corrugated fluted bar, and the hollow member 23 near the downstream, i.e., lip end, is a hollow acetate fiber bar, wherein the hollow corrugated fluted bar has a hollow cavity with a diameter smaller than the hollow cavity of the hollow acetate fiber bar. The aerosol generated in the way firstly passes through the hollow corrugated groove rod with the small cavity diameter and then enters the filtering component after passing through the hollow acetate fiber rod with the large cavity diameter, and when the aerosol passes through the hollow space at the two ends, the change of the cavity diameter can generate the Venturi effect, so that the cooling effect of the aerosol is provided. In addition, the small grooves on the peripheral side of the hollow corrugated grooved bars can be used for aerosol circulation.

Preferably, the outer tube 5 is selected from a breathable material, such as breathable formed paper, in which case ambient air can enter the outer tube 5 through the outer tube 5.

Preferably, the outer tube 5 where the aerosol source material particle part 2 is wrapped has one or more first side flow holes 51, and the number of the first side flow holes 51 is one or more.

That is, the outer tube 5 may be a gas permeable material or a gas impermeable material. When it is an air-permeable material, air can be introduced into the outer tube 5 by its own air permeability. When it is an air impermeable material, air may be introduced into the outer tube 5 by perforating the outer tube 5. Such as mentioned above, the outer tube 5 has first side flow apertures 51 in the region surrounding the aerosol source material particle parts 2 to further replenish air, lower aerosol temperature and increase aerosol volume.

Preferably, the outer side of the outer tube 5 is provided with an indicating mark, and the relative axial movement of the clamping and sealing part 3 and the outer tube 5 to a suction state position can be judged through the indicating mark;

preferably, the blocking member 3 is selected from paper, polylactic acid sheet, acetate fiber or high temperature resistant material, wherein high temperature resistant means that the blocking member can resist the temperature of 250-320 ℃.

A second aspect of the invention provides an aerosol-generating device-aerosol-generating article combination kit comprising an aerosol-generating article according to the first aspect of the invention, and an aerosol-generating device;

the aerosol-generating appliance comprises an aerosol-generating appliance housing N1 and an aerosol-generating article receiving cavity N2 within the aerosol-generating appliance housing N1, the aerosol-generating article receiving cavity N2 having a locking member N3 therein that mates with the protrusion 33;

the locking member N3 is axially movable to drive the snap-seal member 3 to move axially in the end cavity 4.

Preferably, the locking member N3 comprises a support rod N31 and a locking disk N32 located on the support rod N31, the locking disk N32 has a notch N33 with a shape corresponding to the shape of the protrusion 33, and the locking disk N32 can rotate relative to the block component 3;

after the aerosol-generating product is inserted into the aerosol-generating product accommodating cavity N2, the notch N33 corresponds to the protrusion 33, so that the locking disk N32 passes through the protrusion 33 and enters the inside of the sealing member 3, further, the locking disk N32 and the sealing member 3 relatively rotate, the notch N33 is misaligned with the protrusion 33, and the locking disk N32 fixes the sealing member 3 through the protrusion 33, so that the locking member N3 pulls the sealing member 3 through the protrusion 33 to axially move in the end cavity 4.

Preferably, the aerosol-generating device housing N1 further has a lock activation button thereon, and after the aerosol-generating article is inserted into the aerosol-generating article receiving cavity N2, pressing the lock activation button controls the locking member N3 to lock the outer sleeve 5 and pull the outer sleeve 5 to move axially relative to the main body portion of the aerosol-generating article until reaching the smoking state position.

The aerosol-generating appliance-aerosol-generating article combination set is used as follows:

A. the entrapment part 3 is located at a downstream end of the end cavity 4 when the particulate aerosol-generating article is in a non-smoking state, and the aerosol-source material particles part 2 contains aerosol-source material particles 21;

B. inserting the aerosol-generating article into the aerosol-generating device, the notch N33 of the aerosol-generating device corresponding to the position of the protrusion 33, so that the locking disk N32 passes through the protrusion 33 into the interior of the entrapment part 3, further moving the locking disk N32 and the entrapment part 3 in a relative rotation manner, the notch N33 being out of position with the protrusion 33, the locking disk N32 fixing the entrapment part 3 by the protrusion 33, so that the locking part N3 pulls the entrapment part 3 axially in the end cavity 4 by the protrusion 33, pulling the entrapment part 3 to the upstream end of the end cavity 4, dropping the aerosol source material particles 21 contained in the aerosol source material particle part 2 into the end cavity 4, the region of the aerosol source material particle part 2 containing the aerosol source material particles 21 forming an airflow channel 22, and the aerosol-generating device initiating a heating procedure to heat the aerosol source material particles 21 in the end cavity 4 to generate a smokable aerosol-generating article.

The aerosol-generating device and the aerosol-generating article are also provided with marks for facilitating the alignment of the notch N33 and the protrusion 33, so that when the aerosol-generating article is inserted, a consumer can directly determine the positions of the aerosol-generating article and the aerosol-generating device, and the notch N33 and the protrusion 33 are directly aligned after the aerosol-generating article is inserted.

The heating element of an aerosol-generating appliance for use with an aerosol-generating article for use in the present invention may be in the form of a circumferential heating cartridge, it may also be a central heating rod and the heating element may generate heat in the form of electromagnetic heating or resistive heating.

The aerosol-generating article of the present invention is more preferably suitable for use in a circumferentially-type resistively-heated aerosol-generating appliance, as well as an electromagnetically-heated aerosol-generating appliance. When the aerosol-generating device with which it is used is a circumferential resistance-heated aerosol-generating device, it is only necessary to locate the heating cartridge (heating element) axially outside the aerosol source material particles 3. When the aerosol-generating device used in conjunction with it is an electromagnetic heating aerosol-generating device, it is only necessary to place the magnetic field-receptive susceptor axially outside the aerosol-source material particles 3, or to place it on the aerosol-source material particles 3, or more simply to place the susceptor material directly on the outer tube 5 surrounding the aerosol-source material particles 3.

The technical scheme can be freely combined on the premise of no contradiction.

The invention has the following beneficial effects:

1. the aerosol generating product of the invention eliminates a multi-aperture fastener section and a sealing film, but can still carry out two-end constraint on particles through a filter part 1 and a blocking part 3, the aerosol generating product of the invention firstly places aerosol source material particles in the middle section of the aerosol generating product, controls the blocking part 3 during suction, naturally drops the aerosol source material particles to the end under the action of gravity, and forms an airflow channel at the downstream of the aerosol source material particles. The first aspect achieves confinement of the aerosol source material particles across the aerosol source material particles without the use of a multi-aperture fixture section and a sealing membrane, and on the other hand ensures an air flow channel downstream of the aerosol source material particles for focusing the aerosol during suction.

2. The aerosol source material particles are fixed to the middle section of the aerosol generating product in the transportation and storage process, so that the essence and the spice added in the aerosol source material particles can be better preserved, and the aerosol source material particles are prevented from being influenced by the outside at the end parts. Further, if the aerosol-source material particles are filled into the hollow member, the aerosol-source material particles can be filled more closely with a minimum contact area with the air, thereby ensuring better preservation of the additives such as the essence, the flavor or the smoke generating agent added in the aerosol-source material particles. While in use as the capture part 3 moves, particles of the aerosol source material fall into the end cavity, and as the diameter of the end cavity 4 is larger relative to the diameter of the hollow cavity of the hollow part, the particles fall there and are relatively looser, facilitating the generation and release of the aerosol.

3. Because the clamping and sealing part 3 is in a circular truncated cone shape, the diameter of the bottom surface of the clamping and sealing part is larger than that of the top surface, and because the clamping and sealing part does not have the bottom surface (the bottom surface is open), one side of the side surface, which is close to the bottom surface, is not restrained by the bottom surface and can naturally expand towards two sides, so that the friction force at the contact part of the clamping and sealing part 4 and the inner wall of the outer tube 5 is improved, and the clamping and sealing part 3 is more firm in the outer tube 5.

4. The outer tube 5 may be made of a gas permeable material or a gas impermeable material. When it is an air-permeable material, air can be introduced into the outer tube 5 by its own air permeability. When it is an air impermeable material, air may be introduced into the outer tube 5 by perforating the outer tube 5. Such as mentioned above, the outer tube 5 has first side flow apertures 51 in the region surrounding the aerosol source material particle parts 2 to further replenish air, lower aerosol temperature and increase aerosol volume.

5. In a specific using process, the aerosol generating device matched with the aerosol generating product for use can also have the action of pushing the clamping and sealing part 3 to the downstream after the suction is finished, so that the heating element of the device can be further cleaned, the heating cavity of the aerosol generating device is ensured to be cleaner after the aerosol generating product is pulled out, and no aerosol source material particles fall off.

6. The aerosol-generating article of the present invention is more preferably suitable for use in a circumferentially-type resistively-heated aerosol-generating appliance, as well as an electromagnetically-heated aerosol-generating appliance. When the aerosol-generating device used in combination therewith is a circumferential resistance-heating aerosol-generating device, it is only necessary to locate the heating cylinder (heating element) axially outside the aerosol source material particles 3. When the aerosol-generating appliance with which it is used is an electromagnetically heated aerosol-generating appliance, it is only necessary to position the susceptor, which is receptive to a magnetic field, axially outside the particles 3 of aerosol-source material, or to position the particles 3 of aerosol-source material, or more simply to position the susceptor material directly on the outer tube 5 surrounding the particles 3 of aerosol-source material. The invention greatly improves the production efficiency. The adoption of circumferential heating or electromagnetic heating avoids the particles from scattering into the aerosol generating device and avoids the problem of cleanness of the aerosol generating device.

7. The locking member N3 of the aerosol-generating device of the invention and the sealing member 3 of the aerosol-generating article are relatively rotatable to secure the sealing member 3; further, said locking part N3 of the aerosol-generating device is axially movable to bring said sealing part 3 axially in relation to said main part of the aerosol-generating article, thereby performing the function of locking the sealing part 3 and pulling the sealing part 3 in the end cavity 4.

Example 1

As shown in fig. 3-4, the present embodiment is a middle-particle type aerosol-generating article comprising an outer tube 5, and a filter member 1, an aerosol-source-material particle member 2, and a seizing means 3 arranged in this order from a proximal lip end to a distal lip end within the outer tube 5; the aerosol-source-material particle part 2 has an upstream end face which is axially spaced from the upstream end face of the particulate aerosol-generating article by a distance which forms an end cavity 4 by the outer tube 5, and the capture part 3 is located in the end cavity 4 and is axially movable in the end cavity 4.

The entrapment part 3 is located at a downstream end of the end cavity 4 when the particulate aerosol-generating article is in a non-smoking state position, and the section 2 of aerosol-source material particles contains aerosol-source material particles 21;

the entrapment part 3 is located at the upstream end of the end cavity 4 when the particulate aerosol-generating article is in a position of a suction state, aerosol source material particles 21 contained in the aerosol source material particle part 2 drop into the end cavity 4, and an area of the aerosol source material particle part 2 containing the aerosol source material particles 21 forms an airflow channel 22.

That is, the particle-type aerosol-generating article of the invention has two positions for both the aerosol-source material particles and the entrapment part 3 in the non-puffs state, in which the aerosol-source material particles are located in the middle of the aerosol-generating article and the entrapment part 3 is also located furthest downstream of the end cavity 4 to occlude downstream aerosol-source material particles, and in the puffs state. When in the suction state, the entrapment part 3 is pulled down and moved to the most upstream side of the end cavity 4 (the upstream end face of the entrapment part 3 is flush with the upstream end face of the end cavity 4), and the aerosol source material particles fall into the end cavity along with the pulling-down process of the entrapment part 3, but the upstream end face is still occluded by the entrapment part 3.

Example 2

As shown in fig. 11, the segment particle type aerosol-generating article of the present example differs from example 1 in that:

the particulate aerosol-generating article comprises two sections of hollow members 23, and particles 21 of aerosol-source material are contained in the hollow cavity of each section of hollow member 23. The hollow member 23 near the upstream is a hollow corrugated fluted rod and the hollow member 23 near the downstream, i.e., lip end, is a hollow acetate rod, wherein the hollow cavity of the hollow corrugated fluted rod has a smaller diameter than the hollow cavity of the hollow acetate rod. The aerosol generated in the way firstly passes through the hollow corrugated groove rod with the small cavity diameter and then enters the filtering component after passing through the hollow acetate fiber rod with the large cavity diameter, and when the aerosol passes through the hollow space at the two ends, the change of the cavity diameter can generate the Venturi effect, so that the cooling effect of the aerosol is provided. In addition, the small grooves on the peripheral side of the hollow corrugated grooved bars can be used for aerosol circulation.
