Description

Technical Field

[0001] The present invention belongs to the field of aerosol generating articles, in particular to the technical field of aerosol generating articles and aerosol generating appliances using aerosol source material particles, and more specifically relates to an aerosol generating system with an aerosol generating article locking function. Background Art

[0002] The particulate aerosol generating article is a new type of heat-not-burn (HNB) aerosol generating article in recent years. It uses aerosol source material particles instead of aerosol source material sheets as the aerosol generating material. The aerosol source material particles are heated more uniformly than the aerosol source material sheets, and the aerosol diffuses more smoothly along the gaps between the particles than along the gaps between sheet-like materials. Therefore, it is deeply loved by consumers.

[0003] The particulate aerosol generating article is a known product on the market. Refer to the attached Figure 1 to illustrate its structure: Its main structure is an integrated outer sleeve X1, whose far lip end is sealed by a sealing film X2, and then aerosol source material particles X3 are filled into it to form a particulate section. A multi-vent firmware section (commonly known as a "gear part") X4 is arranged downstream of the particulate section, and then an air flow channel section X5 is left for aggregating and accommodating the aerosol (sometimes the air flow channel section X5 is a separate cavity section, or sometimes the air flow channel section X5 is a hollow rod). Downstream of the air flow channel section X5 is a filter section X6, which also serves as a mouthpiece for the user to hold in the mouth. When the aerosol generating article is in use, the far lip end is inserted into the heating appliance. The heating appliance has a heating element that heats the aerosol source material particles to release gaseous flavor components. The gaseous flavor components condense into visible aerosol in the air flow channel section X5 when encountering cold air, and then the aerosol enters the user's mouth after being filtered by the filter section.

[0004] Among them, the air flow channel section X5 is crucial for aerosol formation. According to aerosol science theory, the gaseous flavor components released by heating need to encounter cold to condense into solid particles or liquid particles, and the solid particles or liquid particles need to be suspended in the air to form visible aerosol (commonly known as "smoke" or "fog" or collectively "smoke and fog"). Therefore, in existing particulate aerosol generating articles, this air flow channel section X5 must be provided.

[0005] In addition, because the particles are loose and fluid, if they are not restrained, when the aerosol-generating product is placed horizontally or inverted, the particles will inevitably flow to the downstream airflow channel section X5 on a large scale, resulting in a significant reduction in the particles that can be directly heated by the heating element, and the amount of flavor components released and the subsequent aerosol generated will naturally decrease. To ensure that the particles are fully heated, the particles must be restrained in a limited space near the heating element. This restraint is currently achieved by setting a sealing film X2 upstream of the particle section and providing a multi-hole firmware section X4 downstream of the particle section. The restraints at both ends prevent the particles from flowing everywhere.

[0006] The sealing film X2 is usually a highly breathable thin paper, which is then pasted to the upstream end face of the outer sleeve X1 by means of bonding. The pasting process of the sealing film X2 is complicated and inefficient, and requires special sealing film pasting equipment. In addition, due to the fact that the end face of the outer sleeve X1 is not in the same plane, there are burrs, the thin paper surface is defective, and the glue coating is uneven, the sealing film is not firmly pasted. In the subsequent production process, the sealing film that seals the mouth of the aerosol generating product is debonded, causing the internal storage granular material to leak, which not only pollutes the production environment, but also causes certain other material losses, affecting production efficiency. The current particle-type heated cigarettes are made by sealing with a sealing film and filling with particles. There are problems such as low automation, low sealing success rate (and difficult to detect), and low production efficiency of aerosol generating products. During use, the sealing film is punctured for heating, and the particles are spilled after the aerosol generating product is pulled out of the aerosol generating device, making it difficult to clean the aerosol generating device.

[0007] The material of the multi-through-hole firmware segment X4 is usually ceramic or silicone, and its outer wall is firmly attached to the inner wall of the paper tube by an adhesive. It has at least one axial through hole X41 in the center, and / or at least one peripheral ventilation groove X42 on the periphery. The sizes of these segments are sufficient for smoke to pass through but do not allow aerosol source material particles to pass through, which can block aerosol source material particles and transmit smoke. However, the existence of the multi-through-hole firmware segment has increased costs and many operational inconveniences for the industrial manufacturing of particulate aerosol generating products. Therefore, those skilled in the art have always hoped to cancel the multi-through-hole firmware segment. However, after canceling the multi-through-hole firmware segment, an airflow channel segment must be set downstream of the particle segment to collect and contain aerosols, and this segment can also restrain scattered aerosol source material particles, which poses a dilemma.

[0008] In addition, the aerosol source material particles of existing particulate aerosol - generating articles are all located at the very upstream of the aerosol - generating article (the end face is only separated from the outside by a thin sealing film). During transportation and storage, the aerosol source material particles are easily affected by the outside world. Additionally, to ensure that the aerosol source material particles are more easily heated to generate aerosol during suction and that the generated aerosol can be released better, the aerosol source material particles need to be stacked as loosely as possible and not be too compact. However, this will result in a relatively large contact area between the aerosol source material particles and air during transportation and storage, thus causing the loss of additives such as flavoring agents or fuming agents added to the aerosol source material particles.

[0009] Moreover, in existing products, in order to improve the cooling effect of the smoke, ventilation holes are usually formed on the side wall of the aerosol - generating article to introduce outside ambient air into the airflow channel inside the aerosol - generating article, mix it with the smoke, and cool the smoke. When not in suction, that is, during the transportation or storage of the aerosol - generating article, the existence of these ventilation holes will allow air to enter the inside of the aerosol - generating article and come into contact with the aerosol source material particles more or less, thus causing the loss of additives such as flavoring agents or fuming agents added to the aerosol source material particles, or moisture in the outside air enters the inside of the aerosol - generating article through these ventilation holes, which also easily causes the aerosol source material particles to get damp, being unfavorable for the preservation of the aerosol source material particles.

[0010] Therefore, how to remove the sealing film and the multi - through - hole fixing section, still complete the constraint on the scattered aerosol source material particles, and ensure that the generated aerosol can be smoothly sent to the filtering section. Further, how to make the aerosol source material particles not be at the very upstream of the aerosol - generating article during transportation and storage, as well as the setting of the ventilation holes, are problems that people urgently hope to solve.

[0011] Similarly, an aerosol - generating device that can be used in conjunction with an aerosol - generating article capable of solving the above problems is also urgently needed by people.

[0012] The present invention aims to solve the above problems. Summary of the Invention

[0013] The present invention provides an aerosol - generating system with an aerosol - generating article locking function, which includes an aerosol - generating article and an aerosol - generating device;

[0014] The aerosol - generating device includes an aerosol - generating device housing N1 and an aerosol - generating article receiving cavity N2 located inside the aerosol - generating device housing N1, and a locking member N3 is provided inside the aerosol - generating article receiving cavity N2;

[0015] The aerosol generating article includes a main body portion and an outer sleeve 5 located outside the main body portion;

[0016] The locking member N3 and the outer sleeve 5 are relatively rotatable to fix the outer sleeve 5;

[0017] The locking member N3 is axially movable to drive the outer sleeve 5 to axially move relative to the main body portion of the aerosol generating article.

[0018] The locking member N3 includes a support rod N31 and a locking disk N32 located on the support rod N31, and the locking disk N32 is rotatable relative to the outer sleeve 5.

[0019] Preferably, the aerosol generating article is a particulate aerosol generating article. The main body portion of the particulate aerosol generating article includes an inner tube 1, and a filter member 2 and a hollow member 3 arranged in sequence from the proximal lip end to the distal lip end inside the inner tube 1. An aerosol source material particle member 4 is provided in the hollow cavity of the hollow member 3;

[0020] The outer sleeve 5 has an open top 51 and a sealed bottom surface 52. The open top 51 is located on one side of the filter member 2, and the sealed bottom surface 52 is located on one side of the hollow member 3. The sealed bottom surface 52 seals the aerosol source material particle member 4 in the hollow member 3;

[0021] The outer sleeve 5 is axially movable relative to the main body portion so that there is an axial distance between the upstream end face of the hollow member 3 and the sealed bottom surface 52. The axial distance forms a cavity 6 by the outer sleeve 5, and the aerosol source material particle member 4 in the hollow member 3 moves into the cavity 6.

[0022] In the present invention, the upstream and downstream are determined by the gas flow direction. More specifically, the distal lip end is the upstream and the proximal lip end is the downstream.

[0023] In the present invention, the sequential arrangement does not limit that the two are closely connected, but only limits the sequence. That is, other forms of units can be inserted between any two.

[0024] In the present invention, the inner tube 1 and the outer tube 5 are fixed by friction or slight adhesion, as long as relative movement between the two is prevented during transportation and storage, and relative movement between the two can occur under external force.

[0025] The granular aerosol-generating article of the present invention is not limited to the manufacturing process. It can be in the form of filling, that is, each component is successively filled into the inner tube, or it can be in the form of composite wrapping, that is, each unit is arranged in sequence and then formed into an inner tube by the way of wrapping and rolling. The material of the inner tube is selected from but not limited to paper, ceramic, heat-resistant resin or clay.

[0026] At the other end of the aerosol-generating article, the bottom sealing surface 52 of the outer sleeve 5 is directly selected to restrain the aerosol source material particles, avoiding the problem of the sealing film being not firmly pasted and falling off.

[0027] Preferably, when the granular aerosol-generating article is in the non-puffing state position, the bottom sealing surface 52 of the outer sleeve 5 seals the aerosol source material particle component 4 in the hollow component 3.

[0028] When the granular aerosol-generating article is in the puffing state position, the outer sleeve 5 axially moves relative to the main body part. There is an axial distance between the upstream end surface of the hollow component 3 and the bottom sealing surface 52. This axial distance forms a cavity 6 by the outer sleeve 5. The aerosol source material particle component 4 accommodated in the hollow component 3 falls into the cavity 6 under the action of gravity, and the hollow cavity area of the hollow component 3 forms an air flow channel 7.

[0029] That is to say, when the granular aerosol-generating article of the present invention is in the non-puffing state and the puffing state, both the aerosol source material particles and the bottom sealing surface 52 have two positions. When in the non-puffing state, the bottom sealing surface 52 seals the aerosol source material particle component 4 in the hollow component 3. When in the puffing state, the outer sleeve 5 axially moves relative to the main body part. There is an axial distance between the upstream end surface of the hollow component 3 and the bottom sealing surface 52. This axial distance forms a cavity 6 by the outer sleeve 5. The aerosol source material particle component 4 accommodated in the hollow component 3 falls into the cavity 6 under the action of gravity, and the hollow cavity area of the hollow component 3 forms an air flow channel 7.

[0030] During transportation and storage, since the aerosol source material particles are located in the cavity of the hollow component 3, the aerosol source material particles can be filled more tightly, with the least contact area with air, so as to ensure better preservation of additives such as flavoring agents or fuming agents added to the aerosol source material particles. When entering the puffing state position, as the outer sleeve 5 axially moves relative to the main body part, the aerosol source material particle component 4 falls into the cavity 6 under the action of gravity. Since the diameter size of the cavity 6 is larger, and the particles will be relatively looser after falling here, which is beneficial to the generation and release of aerosol. And the original hollow cavity where the aerosol source material particles are accommodated forms an air flow channel, providing space for the flow and convergence of aerosol.

[0031] Preferably, an opening 521 is provided at the bottom surface 52 of the seal, and the remaining part of the bottom surface 52 of the seal after removing the opening 521 serves as a protruding portion 522. A clamping and sealing member 523 is provided inside the outer sleeve 5. The protruding portion 522 confines the clamping and sealing member 523 inside the outer sleeve 5, and the clamping and sealing member 523 can block the opening 521. The clamping and sealing member 523 can axially move relative to the outer sleeve 5 under the action of an external force. The purpose of the clamping and sealing member 523 being able to axially move relative to the outer sleeve 5 under the action of an external force is that after the locking disc N32 of the aerosol generating device comes, it can enter the outer sleeve 5 by pushing the clamping and sealing member 523.

[0032] Preferably, a notch N33 having the same shape as the protruding portion 522 is provided on the locking disc N32, and the locking disc N32 can rotate relative to the outer sleeve 5; the manner in which the locking disc N32 rotates relative to the outer sleeve 5 here is not limited. After the aerosol generating article is inserted, the outer sleeve 5 can be manually rotated, thereby generating relative rotation between the locking disc N32 and the outer sleeve 5. Of course, the support rod N31 of the aerosol generating device can also drive the locking disc N32 to rotate, thereby generating relative rotation between the locking disc N32 and the outer sleeve 5.

[0033] After the aerosol generating article is inserted into the aerosol generating article receiving cavity N2, the notch N33 corresponds to the position of the protruding portion 522, so that the locking disc N32 passes through the protruding portion 522 and enters the interior of the outer sleeve 5. Further, the locking disc N32 and the outer sleeve 5 rotate relative to each other, and the notch N33 is misaligned with the position of the protruding portion N32. The locking disc N32 fixes the outer sleeve 5 through the protruding portion 522, so that the locking member N3 can pull the outer sleeve 5 to axially move relative to the main body portion of the aerosol generating article through the protruding portion 522.

[0034] Preferably, a locking start button is further provided on the aerosol generating device housing N1. After the aerosol generating article is inserted into the aerosol generating article receiving cavity N2, by pressing the locking start button, the locking member N3 can be controlled to lock the outer sleeve 5 and pull the outer sleeve 5 to axially move relative to the main body portion of the aerosol generating article until it reaches the suction state position.

[0035] Preferably, an indication mark is provided on the outer side of the inner tube 1, and the relative axial movement of the outer sleeve 5 and the main body portion to the suction state position can be judged through the indication mark.

[0036] Preferably, the aerosol generating device and the aerosol generating article further have a mark facilitating the alignment of the notch N33 and the protrusion N32, so that when the consumer inserts the aerosol generating article, the positions of the aerosol generating article and the aerosol generating device can be directly determined, ensuring that the notch N33 and the protrusion N32 are directly aligned after the aerosol generating article is inserted.

[0037] Preferably, the inner tube 5 is made of a breathable material, and external air can enter the inside thereof through the inner tube 5.

[0038] Preferably, the side wall of the hollow member 3 has a ventilation hole 31 radially penetrating the side wall. After the main body portion and the outer sleeve 5 are axially moved relative to each other to the suction state position, external ambient air can enter the hollow cavity of the hollow member 3 through the ventilation hole 31, and the number of the ventilation holes 31 is one or more.

[0039] To improve the cooling effect of the smoke, it is usually necessary to form ventilation holes on the side wall of the aerosol generating article so as to introduce external ambient air into the air flow channel inside the aerosol generating article, mix with the smoke, and cool the smoke. When not in suction, that is, during the transportation or storage of the aerosol generating article, the presence of the ventilation holes will allow air to enter the inside of the aerosol generating article, contact with the aerosol source material particles more or less, resulting in the loss of additives such as flavoring agents or fuming agents added to the aerosol source material particles, or moisture in the external air entering the inside of the aerosol generating article through the ventilation holes, which is also likely to cause the aerosol source material particles to become damp and is not conducive to the preservation of the aerosol source material particles. In the aerosol generating article of the present invention, the outer sleeve 5 is further provided on the outside of the main body portion of the aerosol generating article, and the ventilation holes are located on the main body portion. When the aerosol generating article is in the non-suction state of storage and transportation, the outer sleeve 5 can seal the ventilation holes, and when the aerosol generating article is in the suction state, the outer sleeve 5 axially moves a certain distance relative to the main body portion to expose the ventilation holes, and at this time, external air can enter the inside of the aerosol generating article through the ventilation holes. In addition, the ventilation holes can also be used as an indication mark for the relative axial movement of the outer sleeve 5 and the main body portion to the suction state position, that is, when the outer sleeve 5 and the main body portion move axially relative to each other until the ventilation holes are just completely exposed, it means that the suction state position is reached.

[0040] That is to say, the inner tube can be made of a breathable material or an airtight material. When it is made of a breathable material, air can be introduced into the inner tube through its own breathability. When it is made of an airtight material, air can be introduced into the inner tube by punching the inner tube. Of course, preferably, the ventilation hole method is adopted, so that the ventilation hole can also be directly used as an indication mark for the pulling-out distance, killing two birds with one stone.

[0041] Preferably, the hollow component 3 is one or more sections. The hollow component is a hollow rod with a hollow structure, such as a hollow acetate rod, a hollow corrugated groove rod, a hollow tube with a gear structure, or a hollow paper tube. The structure of the hollow corrugated groove rod and the hollow tube with a gear structure can refer to the patent application for a filling aerosol generating product containing a limiter, which has been applied for by the applicant, with application number 2021226872810. The description of the technical scheme and technical effect of the hollow corrugated groove rod and the hollow tube with a gear structure in the patent is applicable to the present invention.

[0042] Preferably, the sealing member 523 is selected from paper, polylactic acid sheet, acetate fiber or high temperature resistant material, wherein high temperature resistant means being able to withstand a temperature of 250-320° C. The material of the sealing member 523 may be air permeable or airtight. When it is air permeable, it can be applied to a common heated aerosol generating device that allows air to enter from the upstream end of the aerosol generating product. When it is airtight, it can be applied to a closed heated aerosol generating device that does not allow air to enter from the upstream end of the aerosol generating product.

[0043] The outer sleeve 5 is a paper tube, a stainless steel tube or a metal tube that can receive electromagnetic induction. Preferably, the outer sleeve 5 also has a mesh structure. More preferably, the outer sleeve 5 is selected from a metal mesh that receives electromagnetic induction, and the corresponding inner tube has a section of antimagnetic material layer on the side close to the sealing bottom surface 52. This situation is particularly suitable for electromagnetic heating devices. When the aerosol generating product is inserted into the aerosol generating product accommodating cavity, the heating program of the aerosol generating device can be started. However, at this time, since the inner tube has a section of antimagnetic material layer on the side close to the sealing bottom surface 52, the outer sleeve 5 will not receive the electromagnetic generator of the aerosol generating device and generate heat. When the locking component has locked the outer sleeve 5 of the aerosol generating product and formed the cavity 6, the inner tube is away from the electromagnetic induction area, thereby removing the blocking of the electromagnetic reception of the outer sleeve 5, so that the outer sleeve 5 normally receives magnetic induction and is heated, that is, at this time, the outer sleeve 5 is equivalent to the receptor of the electromagnetic heating device. The purpose of such a configuration is also to facilitate the direct activation of the aerosol generating device after the aerosol generating product is inserted, thereby avoiding the cumbersome steps of first activating the locking component and then activating the heating component.

[0044] The aerosol generating system is used as follows:

[0045] A. When the particle-type aerosol generating product is in a non-inhalation state, the sealing bottom surface 52 of the outer sleeve 5 blocks the aerosol source material particle component 4 in the hollow component 3; the aerosol generating product in a non-inhalation state is inserted into the aerosol generating product accommodating chamber N2, and the notch N33 corresponds to the position of the protrusion 522, so that the locking disk N32 passes through the protrusion 522 and enters the interior of the outer sleeve 5;

[0046] B. Start the locking component N3, the locking disk N32 and the outer sleeve 5 rotate relative to each other, the notch N33 is misaligned with the protrusion N32, the locking disk N32 fixes the outer sleeve 5 through the protrusion 522, so that the locking component N3 pulls the outer sleeve 5 to move axially relative to the main body of the aerosol generating product through the protrusion 522, and there is an axial distance between the upstream end surface of the hollow component 3 and the sealing bottom surface 52, and the axial distance is formed by the outer sleeve 5. The aerosol source material particle component 4 contained in the hollow component 3 falls into the cavity 6 under the action of gravity, and the hollow cavity area of the hollow component 3 forms an airflow channel 7, and the aerosol generating product is in the suction state position;

[0047] C. The heating component of the aerosol generating device is started to heat the aerosol source material particle component 4 of the aerosol generating product, thereby generating an aerosol.

[0048] The heating element of the aerosol generating device used in conjunction with the aerosol generating product of the present invention may be in the form of a circumferential heating cylinder or a central heating rod, and the heating element may generate heat in the form of electromagnetic heating or resistance heating.

[0049] The aerosol generating product of the present invention is more preferably suitable for circumferential resistance heating aerosol generating devices and electromagnetic heating aerosol generating devices. When the aerosol generating device used in conjunction with it is a circumferential resistance heating aerosol generating device, it is only necessary to position the heating tube (heating element) axially outside the aerosol source material particles. When the aerosol generating device used in conjunction with it is an electromagnetic heating aerosol generating device, it is only necessary to position the receptor that can receive the magnetic field axially outside the aerosol source material particles, or to set it to the aerosol source material particles, or more simply to directly set the receptor material on the outer sleeve 5 that wraps the aerosol source material particles.

[0050] The above technical solutions can be freely combined under the premise of no contradiction.

[0051] The present invention has the following beneficial effects:

[0052] 1. In the aerosol generating system with the function of locking an aerosol generating product of the present invention, the locking component N3 of the aerosol generating device and the outer sleeve 5 of the aerosol generating product can rotate relative to each other to fix the outer sleeve 5; further, the locking component N3 of the aerosol generating device can move axially to drive the outer sleeve 5 to move axially relative to the main body of the aerosol generating product, thereby realizing the function of locking the outer sleeve 5 and pulling the outer sleeve 5 relative to the main body of the aerosol generating product.

[0053] 2. The aerosol generating product of the present invention eliminates the multi-hole fastener segment and the sealing film, but the particles can still be constrained at both ends by the sealing bottom surface 52 of the outer sleeve 5 during transportation and storage. When the particle-type aerosol generating product of the present invention is in a non-suction state and a suction state, the aerosol source material particles and the sealing bottom surface 52 both have two positions. When in the non-suction state, the sealing bottom surface 52 blocks the aerosol source material particle component 4 in the hollow component 3. When in the suction state, the outer sleeve 5 moves axially relative to the main body, and there is an axial distance between the upstream end surface of the hollow component 3 and the sealing bottom surface 52. The axial distance is formed by the outer sleeve 5 to form a cavity 6. The aerosol source material particle component 4 contained in the hollow component 3 falls into the cavity 6 under the action of gravity, and the hollow cavity area of the hollow component 3 forms an airflow channel 7.

[0054] 3. During transportation and storage, the aerosol source material particles are located in the cavity of the hollow component 3, so the aerosol source material particles can be packed more tightly and have the least contact area with the air, thereby ensuring better preservation of additives such as flavors, fragrances or smoke-generating agents added to the aerosol source material particles. When entering the suction state, as the outer sleeve 5 moves axially relative to the main body, the aerosol source material particle component 4 falls into the cavity 6 under the action of gravity. Since the cavity 6 has a larger diameter, the particles will be relatively loose after falling here, which is conducive to the generation and release of aerosols. The hollow cavity that originally accommodated the aerosol source material particles forms an airflow channel, providing space for the flow and convergence of aerosols.

[0055] 4. To improve the cooling effect of the smoke, it is usually necessary to form ventilation holes on the side wall of the aerosol generating article, so as to introduce external ambient air into the airflow channel inside the aerosol generating article, mix it with the smoke, and cool the smoke. During non-puffing, that is, during the transportation or storage of the aerosol generating article, the existence of these ventilation holes will allow air to enter the inside of the aerosol generating article and come into contact with the aerosol source material particles more or less, resulting in the loss of additives such as flavoring agents or fuming agents added to the aerosol source material particles, or moisture in the external air entering the inside of the aerosol generating article through these ventilation holes, which is also likely to cause the aerosol source material particles to become damp and is not conducive to the preservation of the aerosol source material particles. In the aerosol generating article of the present invention, an outer sleeve 5 is further provided on the outside of the main body part, and the ventilation holes are located on the main body part. When the aerosol generating article is in the non-puffing state of storage and transportation, the outer sleeve 5 can seal the ventilation holes, and when the aerosol generating article is in the puffing state, the outer sleeve 5 axially moves a certain distance relative to the main body part to expose the ventilation holes, and at this time, external air can enter the inside of the aerosol generating article through the ventilation holes. In addition, the ventilation holes can also be used as an indication mark for the relative axial movement of the outer sleeve 5 and the main body part to the puffing state position, that is to say, when the outer sleeve 5 and the main body part move axially relative to each other until the ventilation holes are just completely exposed, it means that the puffing state position is reached.

[0056] 5. The inner tube of the aerosol generating article of the present invention can be made of a breathable material or an airtight material. When it is made of a breathable material, air can be introduced into the inner tube through its own breathability. When it is made of an airtight material, air can be introduced into the inner tube by punching holes in the inner tube. Of course, preferably, the ventilation hole method is adopted, so that the ventilation hole can also be directly used as an indication mark for the pulling-out distance, killing two birds with one stone.

[0057] 6. The aerosol generating article of the present invention is more preferably applicable to a circumferential type resistive heating aerosol generating appliance and an electromagnetic heating aerosol generating appliance. When the aerosol generating appliance used in combination with it is a circumferential type resistive heating aerosol generating appliance, it is only necessary to axially position the heating cylinder (heating element) outside the aerosol source material particles. When the aerosol generating appliance used in combination with it is an electromagnetic heating aerosol generating appliance, it is only necessary to axially position the receptor capable of receiving a magnetic field outside the aerosol source material particles, or set it to the aerosol source material particles, or more simply, directly set receptor material on the outer sleeve wrapping the aerosol source material particles. The present invention greatly improves the production efficiency. By adopting the circumferential heating or electromagnetic heating method, the problem of particles falling into the aerosol generating appliance is avoided, and the problem of cleaning the aerosol generating appliance is also avoided.

[0076] Embodiment 1

[0077] As Figure 4 - Figure 5As shown, the particulate aerosol-generating article of this embodiment includes a main body portion and an outer sleeve 5 located outside the main body portion;

[0078] The main body portion includes an inner tube 1, and a filter component 2 and a hollow component 3 arranged in sequence from the proximal lip end to the distal lip end inside the inner tube 1. An aerosol source material particle component 4 is provided in the hollow cavity of the hollow component 3;

[0079] The outer sleeve 5 has an open top 51 and a sealed bottom surface 52. The open top 51 is located on one side of the filter component 2, and the sealed bottom surface 52 is located on one side of the hollow component 3. The sealed bottom surface 52 seals the aerosol source material particle component 4 in the hollow component 3;

[0080] The outer sleeve 5 can move axially relative to the main body portion so that there is an axial distance between the upstream end face of the hollow component 3 and the sealed bottom surface 52. This axial distance forms a cavity 6 by the outer sleeve 5, and the aerosol source material particle component 4 in the hollow component 3 moves into the cavity 6.

[0081] In this embodiment, the upstream and downstream are determined by the gas flow direction. More specifically, the distal lip end is the upstream and the proximal lip end is the downstream.

[0082] When the particulate aerosol-generating article is in the non-drawing state position, the sealed bottom surface 52 of the outer sleeve 5 seals the aerosol source material particle component 4 in the hollow component 3;

[0083] When the particulate aerosol-generating article is in the drawing state position, the outer sleeve 5 moves axially relative to the main body portion. There is an axial distance between the upstream end face of the hollow component 3 and the sealed bottom surface 52. This axial distance forms a cavity 6 by the outer sleeve 5. The aerosol source material particle component 4 accommodated in the hollow component 3 falls into the cavity 6 under the action of gravity, and the hollow cavity area of the hollow component 3 forms an air flow channel 7.

[0084] An opening 521 is provided at the sealed bottom surface 52, and the remaining part of the sealed bottom surface 52 after removing the opening 521 serves as a protrusion 522. A sealing component 523 is provided inside the outer sleeve 5. The protrusion 522 confines the sealing component 523 inside the outer sleeve 5, and the sealing component 523 can seal the opening 521. The sealing component 523 can move axially relative to the outer sleeve 5 under the action of an external force. The purpose of the sealing component 523 being able to move axially relative to the outer sleeve 5 under the action of an external force is that after the locking disc N32 of the aerosol-generating device comes, it can enter the outer sleeve 5 by pushing the sealing component 523.

[0085] The side wall of the hollow component 3 is provided with ventilation holes 31 that radially penetrate the side wall. After the main body portion and the outer sleeve 5 axially move relative to each other to the suction state position, ambient air can enter the hollow cavity of the hollow component 3 through the ventilation holes 31, and the number of the ventilation holes 31 is one or more. In order to improve the cooling effect of the smoke, ventilation holes are usually formed on the side wall of the aerosol generating article to introduce ambient air into the airflow channel inside the aerosol generating article, mix with the smoke, and cool the smoke. When not in suction, that is, during the transportation or storage of the aerosol generating article, the presence of the ventilation holes will allow air to enter the aerosol generating article and contact the aerosol source material particles more or less, resulting in the loss of additives such as flavoring agents or fuming agents added to the aerosol source material particles, or moisture in the outside air entering the aerosol generating article through the ventilation holes, which is also likely to cause the aerosol source material particles to become damp and is not conducive to the preservation of the aerosol source material particles. In the aerosol generating article of the present invention, the outer side of the main body portion of the aerosol generating article is further provided with an outer sleeve 5, and the ventilation holes are located on the main body portion. When the aerosol generating article is in the non-suction state of storage and transportation, the outer sleeve 5 can seal the ventilation holes. When the aerosol generating article is in the suction state, the outer sleeve 5 axially moves a certain distance relative to the main body portion to expose the ventilation holes, and at this time, ambient air can enter the aerosol generating article through the ventilation holes. In addition, the ventilation holes can also be used as an indication mark for the relative axial movement of the outer sleeve 5 and the main body portion to the suction state position. That is to say, when the outer sleeve 5 and the main body portion move axially relative to each other until the ventilation holes are just completely exposed, it means that the suction state position is reached. At this time, the ventilation holes can also be directly used as an indication mark for the extraction distance, killing two birds with one stone.

[0086] The hollow component 3 is in two sections.

[0087] The snap-sealing component 523 is selected from paper materials.

[0088] Such as Figure 3 、 6 -8, this embodiment further includes the aerosol generating system of the above aerosol generating article. The aerosol generating appliance that is used in matching with the aerosol generating article includes an aerosol generating appliance housing N1 and an aerosol generating article accommodation cavity N2 located in the aerosol generating appliance housing N1. The aerosol generating article accommodation cavity N2 is provided with a locking component N3 that matches the protruding portion 522, and the locking component N3 is fixed to the outer sleeve 5 through the protruding portion 522;

[0089] The locking component N3 can move axially to drive the outer sleeve 5 to axially move relative to the main body portion of the aerosol generating article.

[0090] The locking member N3 includes a support rod N31 and a locking disc N32 located on the support rod N31. The locking disc N32 has a notch N33 with a shape consistent with that of the protrusion 522, and the support rod N31 can drive the locking disc N32 to rotate.

[0091] After the aerosol-generating article is inserted into the aerosol-generating article receiving cavity N2, the notch N33 corresponds to the position of the protrusion 522, so that the locking disc N32 passes through the protrusion 522 and enters the inner part of the outer sleeve 5. Further, the support rod N31 drives the locking disc N32 to rotate, and the notch N33 is misaligned with the protrusion N32. The locking disc N32 fixes the outer sleeve 5 through the protrusion 522, so that the locking member N3 pulls the outer sleeve 5 to axially move relative to the main body part of the aerosol-generating article through the protrusion 522.

[0092] The method for using the aerosol-generating system is as follows:

[0093] A. When the particulate aerosol-generating article is in the non-drawing state position, the sealing bottom surface 52 of the outer sleeve 5 blocks the aerosol source material particle component 4 in the hollow member 3; the aerosol-generating article in the non-drawing state position is inserted into the aerosol-generating article receiving cavity N2, and the notch N33 corresponds to the position of the protrusion 522, so that the locking disc N32 passes through the protrusion 522 and enters the inner part of the outer sleeve 5;

[0094] B. Start the locking member N3. The support rod N31 drives the locking disc N32 to rotate. The notch N33 is misaligned with the protrusion N32. The locking disc N32 fixes the outer sleeve 5 through the protrusion 522, so that the locking member N3 pulls the outer sleeve 5 to axially move relative to the main body part of the aerosol-generating article through the protrusion 522. There is an axial distance between the upstream end surface of the hollow member 3 and the sealing bottom surface 52. This axial distance forms a cavity 6 by the outer sleeve 5. The aerosol source material particle component 4 accommodated in the hollow member 3 drops into the cavity 6 under the action of gravity. The hollow cavity area of the hollow member 3 forms an air flow channel 7, and the aerosol-generating article is in the drawing state position;

[0095] C. The heating component of the aerosol-generating appliance starts to heat the aerosol source material particle component 4 of the aerosol-generating article, thereby generating aerosol.
