Description
Technical Field
The present invention relates to the field of aerosol-generating articles, in particular aerosol-generating articles and aerosol-generating appliances using aerosol source material particles, and more particularly to an aerosol-generating system having a locking function for aerosol-generating articles.
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 aerosol generating device is an integral outer sleeve X1, the far lip end of the integral outer sleeve is sealed by a sealing film X2, then particles X3 of the aerosol source material are filled into the integral 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 intended in use to be inserted with its distal lip end into a heating appliance having a heating element for heating particles of aerosol source material to cause release of gaseous flavour components which condense into a macroscopic aerosol in the airflow passage segment X5 on exposure to cold air, the aerosol then passing 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 or liquid particles, and the solid 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 can 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 confined space adjacent the heating element. This confinement is currently achieved by placing a sealing film X2 upstream of the pellet section and providing a multi-ported fastener section X4 downstream of the pellet section, with the two ends being confined so that pellets do not flow around.
The sealing film X2 is usually made of high-permeability thin paper and then 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 and low in efficiency, and special sealing film adhering equipment is needed. In addition, because the end face 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-ported fastener segment X4 is typically ceramic or silicone and has an outer wall which is fixedly attached to the inner wall of the paper sleeve by an adhesive and has at least one axial through hole X41 in its center and/or at least one peripheral vent groove X42 in its outer periphery which are sized to allow passage of smoke but not particles of the aerosol source material, thereby both blocking the particles of the aerosol source material and transmitting the smoke. 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 (at the end face, separated from the outside only by a thin sealing film) of the aerosol-generating articles, 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 between the aerosol source material particles and the air during transportation and storage, which leads to the loss of the additive such as the flavor or the smoke agent added to the aerosol source material particles.
In addition, in order to improve the cooling effect of the flue gas in the existing products, it is generally necessary to form vent holes on the side wall of the aerosol-generating product, so as to introduce the external ambient air into the airflow channel inside the aerosol-generating product, mix the air with the flue gas, and cool the flue gas. When the aerosol-generating article is not smoked, that is to say, during transportation or storage of the aerosol-generating article, the presence of the vent holes can allow air to enter the interior of the aerosol-generating article and to come into more or less contact with the particles of the aerosol-source material, thereby causing the loss of the additive such as the perfume or the smoke suppressant added to the particles of the aerosol-source material, or moisture in the outside air to enter the interior of the aerosol-generating article through the vent holes, which can also easily cause the particles of the aerosol-source material to become damp, and thus can adversely affect the preservation of the particles of the aerosol-source material.
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 further preventing the aerosol source material particles from being located at the most upstream of the aerosol generating product during transportation and storage, and arranging the vent holes.
There is also a need for aerosol-generating devices for use with aerosol-generating articles that address the above-mentioned problems.
The utility model aims to solve the problems.

The material of the inner tube 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 bottom surface 52 of the seal of the outer sleeve 5 to restrain aerosol source material particles, so that the problems that the seal film is not firmly adhered and falls off are avoided.
Preferably, the closure base surface 52 of the outer sleeve 5 closes off the aerosol-source material particle section 4 in the hollow section 3 when the particulate aerosol-generating article is in a non-smoking state position;
when the particulate aerosol-generating article is in a smoking state position, the outer sleeve 5 is moved axially relative to the body portion, there is an axial distance between the upstream end face of the hollow member 3 and the base face 52 of the closure, the axial distance forming a cavity 6 by the outer sleeve 5, the particulate component 4 of aerosol source material contained in the hollow member 3 falling under gravity into the cavity 6, the hollow cavity region of the hollow member 3 forming an air flow channel 7.

Because the aerosol source material particles are positioned in the cavity of the hollow part 3 during transportation and storage, the aerosol source material particles can be filled more tightly and have the smallest contact area with air, thereby ensuring better preservation of additives such as essence, spice or smoke agent added in the aerosol source material particles. And on entering the suction state position, as the outer sleeve 5 moves axially relative to the body portion, the aerosol source material particle parts 4 drop under gravity into the cavities 6, where the particles drop relatively more loosely due to the larger diameter of the cavities 6, facilitating aerosol generation and release. And the hollow cavity originally containing the aerosol source material particles forms an airflow channel to provide a space for the flow and convergence of the aerosol.
Preferably, the bottom surface 52 of the seal has an opening 521, and the remaining portion of the bottom surface 52 of the seal except the opening 521 is used as a protrusion 522, the outer sleeve 5 has a sealing member 523 therein, the protrusion 522 is used to limit the sealing member 523 into the outer sleeve 5, and the sealing member 523 can seal the opening 521, and the sealing member 523 can move axially relative to the outer sleeve 5 under the action of external force. The purpose of the snap-seal member 523 being axially displaceable relative to the outer sleeve 5 under the action of an external force is that the locking disk N32 of the aerosol-generating appliance can in turn be pushed into the outer sleeve 5 by pushing the snap-seal member 523.
Preferably, the locking disk N32 has a notch N33 corresponding to the shape of the protrusion 522, and the locking disk N32 can rotate relative to the outer sleeve 5; the manner in which the locking disk N32 is rotationally moved relative to the outer sleeve 5 is not limited herein and the outer sleeve 5 may be manually rotated after insertion of the aerosol-generating article to produce relative rotation between the locking disk N32 and the outer sleeve 5.

In order to improve the cooling effect of the flue gas, it is often necessary to form ventilation holes in the side walls of the aerosol-generating article in order to introduce ambient air into the airflow channels inside the aerosol-generating article, mix it with the flue gas and cool it. When the aerosol-generating article is not smoked, that is to say, during transportation or storage of the aerosol-generating article, the presence of the vent holes can allow air to enter the interior of the aerosol-generating article and to come into more or less contact with the particles of the aerosol-source material, thereby causing the loss of the additive such as the perfume or the smoke suppressant added to the particles of the aerosol-source material, or moisture in the outside air to enter the interior of the aerosol-generating article through the vent holes, which can also easily cause the particles of the aerosol-source material to become damp, and thus can adversely affect the preservation of the particles of the aerosol-source material.

That is, the inner tube may be a breathable material or a non-breathable material. When it is an air permeable material, air can be introduced into the inner tube by its own air permeability. When it is an air impermeable material, air may be introduced into the inner tube by perforating the inner tube. Of course, the mode of the vent hole is preferably adopted, so that the vent hole can also be directly used as an indicator for the pulling-out distance, and the two purposes are achieved at the same time.

The outer sleeve 5 is a paper tube, a stainless steel tube or a metal tube capable of receiving electromagnetic induction. Preferably said outer sleeve 5 is also provided with a mesh structure. More preferably, the outer sleeve 5 is selected from a metal mesh which receives electromagnetic induction, and the corresponding inner tube has a section of antimagnetic material layer on the side close to the bottom surface 52 of the seal. This is particularly the case for electromagnetic heating appliances, where the heating process of the aerosol-generating appliance can be initiated when the aerosol-generating article is inserted into the aerosol-generating article-receiving cavity, but now the outer sleeve 5 does not receive the electromagnetic generator of the aerosol-generating appliance and generates heat because of the presence of a layer of anti-magnetic material on the side of the inner tube adjacent the underside 52 of the closure, and when the locking means has locked the outer sleeve 5 of the aerosol-generating article and the cavity 6 is formed, the inner tube is moved away from the electromagnetic induction region, thereby unblocking the electromagnetic reception of the outer sleeve 5 and allowing the outer sleeve 5 to normally receive magnetic induction and be heated, i.e. when the outer sleeve 5 acts as a susceptor for the electromagnetic heating appliance. The object of such an arrangement is also to facilitate direct actuation of the aerosol-generating device after insertion of the aerosol-generating article, avoiding the cumbersome steps of first actuating the locking component and then actuating the heating component.

The present invention aerosol-generating article is more preferably suitable for use in a circumferentially-type resistance-heated aerosol-generating appliance, and an electromagnetically-type heated aerosol-generating appliance. When the aerosol-generating device used in combination therewith 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. When the aerosol-generating device used in conjunction with it is an electromagnetic heated aerosol-generating device, it is only necessary to locate the magnetic field-receptive susceptor axially outside the aerosol-source material particles, or to locate the aerosol-source material particles, or more simply to locate the susceptor material directly on the outer sleeve 5 surrounding the aerosol-source material particles.

When in the suction state, the outer sleeve 5 is moved axially relative to the body portion, there being an axial distance between the upstream end face of the hollow part 3 and the closure base face 52, the axial distance forming a cavity 6 by the outer sleeve 5, the parts 4 of aerosol source material particles contained in the hollow part 3 falling under gravity into the cavity 6, the hollow cavity region of the hollow part 3 forming an air flow passage 7.
3. Because the aerosol source material particles are positioned in the cavity of the hollow part 3 during transportation and storage, the aerosol source material particles can be filled more tightly and have the smallest contact area with air, thereby ensuring better preservation of additives such as essence, spice or smoke agent added in the aerosol source material particles. And on entering the suction state position, as the outer sleeve 5 moves axially relative to the body portion, the aerosol source material particle parts 4 drop under gravity into the cavities 6, where the particles drop relatively more loosely due to the larger diameter of the cavities 6, facilitating aerosol generation and release. And the hollow cavity originally containing the aerosol source material particles forms an airflow channel to provide a space for the flow and convergence of the aerosol.
4. In order to improve the cooling effect of the flue gas, it is often necessary to form ventilation holes in the side walls of the aerosol-generating article in order to introduce ambient air into the airflow channels inside the aerosol-generating article, mix it with the flue gas and cool it. When the aerosol-generating article is not smoked, that is to say, during transportation or storage of the aerosol-generating article, the presence of the vent holes can allow air to enter the interior of the aerosol-generating article and to come into more or less contact with the particles of the aerosol-source material, thereby causing the loss of the additive such as the perfume or the smoke suppressant added to the particles of the aerosol-source material, or moisture in the outside air to enter the interior of the aerosol-generating article through the vent holes, which can also easily cause the particles of the aerosol-source material to become damp, and thus can adversely affect the preservation of the particles of the aerosol-source material. And the utility model discloses the main part outside of aerosol generation goods still has outer sleeve 5, and the air vent is located the main part, and when aerosol generation goods stored the non-suction state of transportation, outer sleeve 5 can seal the air vent, and when aerosol generation goods were in the suction state, outer sleeve 5 was for main part axial displacement certain distance, made the air vent expose, outside air can get into inside aerosol generation goods through the air vent this moment. In addition to this, the vent hole may also serve as an indicator of relative axial movement of the outer sleeve 5 and the main body portion to the suction state position, i.e. when the outer sleeve 5 and the main body portion are moved axially relative to each other until the vent hole is just fully exposed, and indicates that the suction state position is reached.
5. The inner tube of the aerosol-generating article of the present invention may be a breathable material or may be a non-breathable material. When it is an air permeable material, air can be introduced into the inner tube by its own air permeability. When it is an air impermeable material, air may be introduced into the inner tube by perforating the inner tube. Of course, the mode of the vent hole is preferably adopted, so that the vent hole can also be directly used as an indicator for the pulling-out distance, and the two purposes are achieved at the same time.
6. The present invention aerosol-generating article is more preferably suitable for use in a circumferentially-type resistance-heated aerosol-generating appliance, and an electromagnetically-type heated aerosol-generating appliance. When the aerosol-generating device used in combination therewith 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. When the aerosol generating device used with the aerosol generating device is an electromagnetic heating aerosol generating device, the susceptor capable of receiving the magnetic field is only required to be axially positioned outside the aerosol source material particles, or to be positioned on the aerosol source material particles, or more simply, the susceptor material is directly arranged on the outer sleeve wrapping the aerosol source material particles. The utility model discloses production efficiency has been improved greatly. 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.

Example 1
As shown in fig. 4-5, the present embodiment particulate aerosol-generating article comprises a body portion and an outer sleeve 5 located outside the body portion;
the main body part comprises an inner pipe 1, and a filtering part 2 and a hollow part 3 which are arranged in the inner pipe 1 from a near lip end to a far lip end in sequence, wherein a hollow cavity of the hollow part 3 is provided with an aerosol source material particle part 4;
the outer sleeve 5 has a top opening 51 and a bottom surface 52 of the seal, wherein the top opening 51 is located at one side of the filter element 2, the bottom surface 52 of the seal is located at one side of the hollow element 3, and the bottom surface 52 of the seal is used for sealing off the particle part 4 of the aerosol source material in the hollow element 3;
the outer sleeve 5 is axially movable relative to the body portion to provide an axial distance between the upstream end face of the hollow member 3 and the closure base surface 52, the axial distance defining a cavity 6 defined by the outer sleeve 5, the parts 4 of aerosol source material particles in the hollow member 3 being moved into the cavity 6.
The upstream and downstream mentioned in this embodiment are determined in the gas flow direction. More specifically, the distal labial end is upstream and the proximal labial end is downstream.
The closure base surface 52 of the outer sleeve 5 closes off the aerosol-source material particle sections 4 in the hollow section 3 when the particulate aerosol-generating article is in a non-aspirating position;
when the particulate aerosol-generating article is in a smoking state position, the outer sleeve 5 is moved axially relative to the body portion, there is an axial distance between the upstream end face of the hollow member 3 and the base face 52 of the closure, the axial distance forming a cavity 6 by the outer sleeve 5, the particulate component 4 of aerosol source material contained in the hollow member 3 falling under gravity into the cavity 6, the hollow cavity region of the hollow member 3 forming an air flow channel 7.
The bottom surface 52 of the seal has an opening 521, and the remaining portion of the bottom surface 52 of the seal except the opening 521 is used as a protrusion 522, the outer sleeve 5 has a sealing member 523 therein, the protrusion 522 is used to confine the sealing member 523 in the outer sleeve 5, and the sealing member 523 can seal the opening 521, and the sealing member 523 can move axially relative to the outer sleeve 5 under the action of external force. The purpose of the snap-seal member 523 being axially displaceable relative to the outer sleeve 5 under the action of an external force is that the locking disk N32 of the aerosol-generating appliance can in turn be pushed into the outer sleeve 5 by pushing the snap-seal member 523.
The side wall of the hollow part 3 is provided with vent holes 31 which radially penetrate through the side wall, after the main body part and the outer sleeve 5 are relatively axially moved to a suction state position, external environment air can enter the hollow cavity of the hollow part 3 through the vent holes 31, and the number of the vent holes 31 is one or more. In order to improve the cooling effect of the flue gas, it is often necessary to form ventilation holes in the side walls of the aerosol-generating article in order to introduce ambient air into the airflow channels inside the aerosol-generating article, mix it with the flue gas and cool it. When the aerosol-generating article is not smoked, that is to say, during transportation or storage of the aerosol-generating article, the presence of the vent holes can allow air to enter the interior of the aerosol-generating article and to come into more or less contact with the particles of the aerosol-source material, thereby causing the loss of the additive such as the perfume or the smoke suppressant added to the particles of the aerosol-source material, or moisture in the outside air to enter the interior of the aerosol-generating article through the vent holes, which can also easily cause the particles of the aerosol-source material to become damp, and thus can adversely affect the preservation of the particles of the aerosol-source material. And the utility model discloses the main part outside of aerosol generation goods still has outer sleeve 5, and the air vent is located the main part, and when aerosol generation goods stored the non-suction state of transportation, outer sleeve 5 can seal the air vent, and when aerosol generation goods were in the suction state, outer sleeve 5 was for main part axial displacement certain distance, made the air vent expose, outside air can get into inside aerosol generation goods through the air vent this moment. In addition to this, the vent hole may also serve as an indicator of relative axial movement of the outer sleeve 5 and the main body portion to the suction state position, i.e. when the outer sleeve 5 and the main body portion are moved axially relative to each other until the vent hole is just fully exposed, and indicates that the suction state position is reached. At this moment, the air vent can also be directly used as an indicator of the pulling-out distance, thereby achieving two purposes at a time.
