Description

Technical Field

[0001] The present invention belongs to the field of aerosol generating articles, and in particular to the field of aerosol generating articles using aerosol source material particles, and more specifically relates to a dropping type particulate aerosol generating article and an aerosol generating system. Background Art

[0002] Particulate aerosol generating articles are a new type of heat-not-burn (HNB) aerosol generating articles in recent years. They use aerosol source material particles instead of aerosol source material sheets as aerosol generating materials. 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, they are deeply loved by consumers.

[0003] Particulate aerosol generating articles are known products 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-vented firmware section (commonly known as a "gear part") X4 is provided downstream of the particulate section, and then an air flow channel section X5 is left for collecting and containing the aerosol (sometimes the air flow channel section X5 is a separate cavity, 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 using this aerosol generating article, the far lip end is inserted into a heating appliance, and the heating appliance has a heating element to heat 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"). Therefore, in existing particulate aerosol generating articles, this air flow channel section X5 must be provided.

[0005] In addition, since the particles are loose and flowable, if not constrained, when the aerosol-generating article is placed horizontally or inverted, the particles will inevitably flow downstream into the gas flow channel section X5 on a large scale, resulting in a significant reduction in the particles that can be directly heated by the heating element. Naturally, the amount of flavor components released and the subsequent generated aerosol will also decrease. To ensure that the particles are fully heated, the particles must be constrained within a limited space near the heating element. This constraint is currently achieved by setting a sealing film X2 upstream of the particle section and providing a multi-vent firmware section X4 downstream of the particle section. The two-end constraint prevents the particles from flowing around.

[0006] The sealing film X2 is usually a highly breathable thin paper, which is then pasted onto the upstream end face of the outer sleeve X1 by means of bonding. The process of pasting this sealing film X2 is complex and inefficient, and requires special equipment for pasting the sealing film. In addition, due to factors such as the end faces of the outer sleeve X1 not being in the same plane, having burrs, defects on the surface of the thin paper, and uneven glue application, the sealing film is not firmly pasted, and the sealing film that seals the mouth of the aerosol-generating article comes off during subsequent production, resulting in leakage of the internal stored particle material, which not only pollutes the production environment but also causes certain losses of other materials and affects production efficiency. The current particulate heated cigarette is made by using a sealing film for sealing and filling particles. There are problems of low automation, low sealing success rate (and difficult to detect), and low production efficiency of the aerosol-generating article. During use, the sealing film is punctured for heating, and the particles spill out after the aerosol-generating article is removed from the aerosol-generating device, making it difficult to clean the aerosol-generating device.

[0007] The material of the multi-vent firmware section X4 is usually ceramic or silicone. Its outer wall is firmly pasted on 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 its outer periphery. Their sizes are all large enough for the smoke to pass through but do not allow the aerosol source material particles to pass through, which can block the aerosol source material particles and transfer the smoke. However, the presence of the multi-vent firmware section brings about an increase in cost and many operational inconveniences to the industrial manufacturing of the particulate aerosol-generating article. Therefore, those skilled in the art have always hoped to eliminate this multi-vent firmware section. However, after eliminating the multi-vent firmware section, it is necessary to set up a gas flow channel section for summarizing and accommodating the aerosol downstream of the particle section, and this section can also constrain the scattered aerosol source material particles, presenting 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 (only separated from the outside by a thin sealing film at the end face), and during transportation and storage, the aerosol source material particles are very likely to be affected by the outside. Additionally, in order 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 piled up as loosely as possible and not be particularly compact. However, this will result in a relatively large contact area between the aerosol source material particles and air during transportation and storage, thereby causing the loss of additives such as flavoring agents or fuming agents added to the aerosol source material particles.

[0009] In addition, 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, thereby 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 become damp and is not conducive to the preservation of the aerosol source material particles.

[0010] Therefore, how to cancel the sealing film and the multi-through-hole fixing section, still complete the restraint of the scattered aerosol source material particles, and ensure that the generated aerosol can be smoothly sent to the filter section. Further, how to make the aerosol source material particles not 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] The present invention aims to solve the above problems. Summary of the Invention

[0012] In a first aspect of the present invention, a drop-feed particulate aerosol-generating article is provided, which includes a main body part and an outer sleeve 5 located outside the main body part;

[0013] The main body part 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;

[0014] The outer sleeve 5 has an open top 51 and a sealed bottom surface 52, where the open top 51 is located on the side of the filter component 2, and the sealed bottom surface 52 is located on the side of the hollow component 3. The sealed bottom surface 52 seals the aerosol source material particle component 4 in the hollow component 3;

[0015] 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.

[0016] Among them, the outer sleeve 5 can be manually pulled or the main body portion can be pulled, so that the outer sleeve 5 moves axially relative to the main body portion. Or a pulling device can be provided on the aerosol generating device to generate a relative axial movement between the two. Of course, preferably, this function is achieved by the aerosol generating device described below.

[0017] In the present invention, the upstream and downstream are determined by the gas flow direction. More specifically, the far lip end is the upstream and the near lip end is the downstream.

[0018] The sequential arrangement in the present invention is not limited to the two being tightly connected, but only to the limitation of the sequence. That is to say, other forms of units can be inserted between any two.

[0019] In the present invention, the inner tube 1 and the outer tube 5 are fixed by friction or slight adhesion, as long as it is ensured that the two do not move relative to each other during transportation and storage, and the two can move relative to each other under external force.

[0020] Preferably, 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;

[0021] 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 region of the hollow component 3 forms an air flow channel 7.

[0022] That is to say, when the particulate aerosol generating article of the present invention is in the non-drawing state and the drawing state, both the aerosol source material particles and the bottom surface 52 of the seal have two positions. When in the non-drawing state, the bottom surface 52 of the seal blocks the aerosol source material particle component 4 in the hollow member 3. When in the drawing state, the outer sleeve 5 axially moves relative to the main body portion, and there is an axial distance between the upstream end surface of the hollow member 3 and the bottom surface 52 of the seal. This axial distance forms a cavity 6 by the outer sleeve 5, and the aerosol source material particle component 4 accommodated in the hollow member 3 falls into the cavity 6 under the action of gravity. The hollow cavity region of the hollow member 3 forms an air flow channel 7.

[0023] During transportation and storage, since the aerosol source material particles are located in the cavity of the hollow member 3, the aerosol source material particles can be packed more tightly, with the least contact area with air, thus ensuring better preservation of additives such as flavoring agents or fuming agents added to the aerosol source material particles. When entering the drawing state position, as the outer sleeve 5 axially moves relative to the main body portion, the aerosol source material particle component 4 falls into the cavity 6 under the action of gravity. Since the diameter of the cavity 6 is larger, the particles will be relatively looser after falling here, which is beneficial to the generation and release of aerosol. And the hollow cavity that originally accommodated the aerosol source material particles forms an air flow channel, providing space for the flow and convergence of aerosol.

[0024] Preferably, an opening 521 is provided at the bottom surface 52 of the seal, and the remaining part of the bottom surface 52 except the opening 521 serves as a protrusion 522. A clamping and sealing component 523 is provided inside the outer sleeve 5. The protrusion 522 confines the clamping and sealing component 523 into the outer sleeve 5, and the clamping and sealing component 523 can block the opening 521. The clamping and sealing component 523 can axially move relative to the outer sleeve 5 under the action of an external force. The purpose of the clamping and sealing component 523 being able to axially move relative to the outer sleeve 5 under the action of an external force is that when the locking disk N32 of the aerosol generating device comes, it can enter the outer sleeve 5 by pushing the clamping and sealing component 523.

[0025] An indication mark is provided on the outer side of the inner tube 1, and it can be judged whether the outer sleeve 5 and the main body portion axially move relative to each other to the drawing state position through the indication mark.

[0026] The dropping type particulate aerosol generating article of the present invention does not limit the manufacturing process. It can use the filling form, that is, filling each component into the inner tube in sequence, or it can use the composite wrapping form, that is, arranging each unit in sequence and then forming the inner tube by wrapping and rolling. The material of the inner tube is selected from but not limited to paper, ceramic, heat-resistant resin or clay.

[0027] 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 unreliable adhesion and detachment of the sealing film.

[0028] Preferably, the inner tube 5 is made of a breathable material, and external air can enter its interior through the inner tube 5.

[0029] Preferably, the side wall of the hollow member 3 has ventilation holes 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 holes 31, and the number of the ventilation holes 31 is one or more. In order 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 existence of the ventilation holes will cause air to enter the inside of 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 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 get 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 outside the main body portion, 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 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.

[0030] 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 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 extraction distance, killing two birds with one stone.

[0031] Preferably, the hollow member 3 is one or more segments. The hollow member is a hollow rod with a hollow structure, such as a hollow acetate fiber rod, a hollow corrugated groove rod, a hollow tube with a gear structure, or a hollow paper tube. The structures of the hollow corrugated groove rod and the hollow tube with a gear structure can refer to the patent application with the application number 2021226872810 and the title of an aerosol generating article for filling type containing a limiting member filed by the present applicant. The descriptions of the technical solutions and technical effects of the hollow corrugated groove rod and the hollow tube with a gear structure in this patent are applicable to the present invention.

[0032] Preferably, the clamping and sealing member 523 is selected from paper materials, polylactic acid sheets, acetate fiber, or high-temperature resistant materials, where high-temperature resistant means it can withstand a temperature of 250 - 320 °C. The material of the clamping and sealing member 523 can be breathable or non-breathable. When it is breathable, it can be applicable to ordinary heating aerosol generating appliances that allow air to enter from the upstream end of the aerosol generating article. When it is non-breathable, it can be applicable to airtight heating aerosol generating appliances that do not allow air to enter from the upstream end of the aerosol generating article.

[0033] The second aspect of the present invention provides an aerosol generating system, which includes the aerosol generating article described in the first aspect of the present invention and an aerosol generating appliance;

[0034] The aerosol generating appliance includes an aerosol generating appliance housing N1 and an aerosol generating article receiving cavity N2 located within the aerosol generating appliance housing N1. The aerosol generating article receiving cavity N2 has a locking member N3 that matches the protruding portion 522, and the locking member N3 is fixed to the outer sleeve 5 through the protruding portion 522;

[0035] The locking member N3 can move axially to drive the outer sleeve 5 to move axially relative to the main body portion of the aerosol generating article.

[0036] Preferably, the locking member N3 includes a support rod N31 and a locking disk N32 located on the support rod N31. The locking disk N32 has a notch N33 with the same shape as the protruding portion 522, and the locking disk N32 can rotate relative to the outer sleeve 5; the manner in which the locking disk N32 rotates relative to the outer sleeve 5 is not limited here. After the aerosol generating article is inserted, the outer sleeve 5 can be manually rotated to generate relative rotation between the locking disk N32 and the outer sleeve 5. Of course, the support rod N31 of the aerosol generating appliance can also drive the locking disk N32 to rotate, thereby generating relative rotation between the locking disk N32 and the outer sleeve 5.

[0037] After the aerosol generating product is inserted into the aerosol generating product accommodating cavity N2, 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. Further, the locking disk N32 and the outer sleeve 5 rotate relative to each other, and the notch N33 is misaligned with the protrusion 522. 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 part of the aerosol generating product through the protrusion 522.

[0038] Preferably, the aerosol generating device housing N1 also has a locking start button. After the aerosol generating product is inserted into the aerosol generating product accommodating chamber N2, pressing the locking start button can control the locking component N3 to lock the outer sleeve 5 and pull the outer sleeve 5 to move axially relative to the main part of the aerosol generating product until it reaches the suction state position.

[0039] Preferably, the aerosol generating device and the aerosol generating product also have a mark for aligning the notch N33 with the protrusion 522, so that the consumer can directly determine the position of the aerosol generating product and the aerosol generating device when inserting the aerosol generating product, and ensure that the notch N33 and the protrusion 522 are directly aligned after the aerosol generating product is inserted.

[0040] The outer sleeve 5 is a paper tube, a stainless steel tube, or a metal tube capable of receiving electromagnetic induction. Preferably, the outer sleeve 5 also has a mesh structure. More preferably, the outer sleeve 5 is made of a metal mesh capable of receiving electromagnetic induction, and the corresponding inner tube has a layer of antimagnetic material on the side near the sealed bottom surface 52. This is particularly suitable for electromagnetic heating devices. Once the aerosol-generating product is inserted into the aerosol-generating product receiving cavity, the aerosol-generating device's heating process can be initiated. However, since the inner tube has a layer of antimagnetic material on the side near the sealed bottom surface 52, the outer sleeve 5 does not receive the electromagnetic generator of the aerosol-generating device and generate heat. Once the locking component has locked the outer sleeve 5 of the aerosol-generating product and formed the cavity 6, the inner tube moves away from the electromagnetic induction area, thereby removing the barrier to electromagnetic reception of the outer sleeve 5 and allowing the outer sleeve 5 to receive magnetic induction and heat normally. In other words, the outer sleeve 5 now acts as a sensor for the electromagnetic heating device. The purpose of this arrangement is also to facilitate the direct activation of the aerosol generating device after the aerosol generating product is inserted, avoiding the tedious steps of first activating the locking component and then activating the heating component.

[0041] Preferably, the aerosol generating system is used as follows:

[0042] A. When the particulate aerosol - generating article is in the non - puffing state position, the sealing bottom surface 52 of the outer sleeve 5 seals the aerosol - source material particle component 4 in the hollow component 3; inserting the aerosol - generating article in the non - puffing state position 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 interior of the outer sleeve 5;

[0043] B. Activate the locking component N3, the locking disc N32 and the outer sleeve 5 rotate relative to each other, the notch N33 is misaligned with the position of the protrusion 522, the locking disc N32 fixes the outer sleeve 5 through the protrusion 522, so that the locking component 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 component 3 and the sealing bottom surface 52, and 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 drops into the cavity 6 under the action of gravity. The hollow cavity area of the hollow component 3 forms an air flow channel 7, and the aerosol - generating article is in the puffing state position;

[0044] C. The heating component of the aerosol - generating device starts to heat the aerosol - source material particle component 4 of the aerosol - generating article, thereby generating aerosol.

[0045] The heating element of the aerosol - generating device used in conjunction with the aerosol - generating article of the present invention can be in the form of a circumferential heating cylinder or a central heating rod, and the form of heat generation of the heating element can be electromagnetic heating or resistance heating.

[0046] The aerosol - generating article of the present invention is more preferably applicable to a circumferential - type resistance - heating aerosol - generating device and an electromagnetic - type heating aerosol - generating device. When the aerosol - generating device used in conjunction with it is a circumferential - type resistance - heating aerosol - generating device, only the heating cylinder heating element needs to be axially located outside the aerosol - source material particles. When the aerosol - generating device used in conjunction with it is an electromagnetic - type heating aerosol - generating device, only the receptor that can receive the magnetic field needs to be axially located outside the aerosol - source material particles, or set to the aerosol - source material particles, or more simply, directly set the receptor material on the outer sleeve 5 that wraps the aerosol - source material particles.

[0047] The above - mentioned technical solutions can be freely combined on the premise of no contradiction.

[0048] The present invention has the following beneficial effects:

[0049] 1. In the aerosol generating article of the present invention, the multi-vented firmware segment and the sealing film are cancelled, but during transportation and storage, the particles can still be constrained at both ends by the sealing bottom surface 52 of the outer sleeve 5. When the particulate aerosol generating article of the present invention is in the non-drawing state and the drawing state, both the aerosol source material particles and the sealing bottom surface 52 have two positions. When in the non-drawing state, the sealing bottom surface 52 blocks the aerosol source material particle component 4 in the hollow component 3. When in the drawing state, the outer sleeve 5 axially moves relative to the main body portion, and there is an axial distance between the upstream end surface of the hollow component 3 and the sealing bottom surface 52. This axial distance forms a cavity 6 by the outer sleeve 5, and the aerosol source material particle component 4 accommodated in the hollow component 3 drops into the cavity 6 under the action of gravity, and the hollow cavity region of the hollow component 3 forms an air flow channel 7.

[0050] 2. 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 packed more tightly, with the least contact area with air, thus ensuring better preservation of additives such as flavoring agents or fuming agents added to the aerosol source material particles. When entering the drawing state position, as the outer sleeve 5 axially moves relative to the main body portion, the aerosol source material particle component 4 drops into the cavity 6 under the action of gravity. Since the diameter of the cavity 6 is larger, the particles will be relatively looser after dropping here, which is beneficial to the generation and release of aerosol. And the hollow cavity originally accommodating the aerosol source material particles forms an air flow channel, providing space for the flow and convergence of aerosol.

[0051] 3. 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. During non-puffing, that is, during the transportation or storage of the aerosol generating article, the existence of the ventilation holes will allow air to enter the inside of 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 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, an outer sleeve 5 is further provided outside the main body portion, and the ventilation holes are located on the main body portion. 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 portion to expose the ventilation holes, and at this time, the outside 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 puffing 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 puffing state position is reached.

[0052] 4. 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.

[0053] 5. The aerosol generating article of the present invention is more preferably applicable to a circumferential type resistive heating aerosol generating device and an electromagnetic heating aerosol generating device. When the aerosol generating device used in combination with it is a circumferential type resistive heating aerosol generating device, it only needs to axially position the heating cylinder (heating element) outside the aerosol source material particles. When the aerosol generating device used in combination with it is an electromagnetic heating aerosol generating device, it only needs to axially position the receptor capable of receiving the magnetic field outside the aerosol source material particles, or set it to the aerosol source material particles, or more simply, directly set the 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 device is avoided, and the problem of cleaning the aerosol generating device is also avoided.

[0054] 6. The locking member N3 of the aerosol generating device of the present invention and the outer sleeve 5 of the aerosol generating article are rotatable relative to each other to fix the outer sleeve 5; further, the locking member N3 of the aerosol generating device can move axially to drive the outer sleeve 5 to move axially relative to the main body portion of the aerosol generating article, so as to lock the outer sleeve 5 and perform the function of toggling the outer sleeve 5 relative to the main body portion of the aerosol generating article.

[0073] Example 1

[0074] As Figures 3 - 4 shown, the blanking type particulate aerosol generating article of this embodiment includes a main body portion and an outer sleeve 5 located outside the main body portion;

[0075] 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;

[0076] 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;

[0077] 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.

[0078] 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.

[0079] When the particulate aerosol generating article is in the non - suction 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;

[0080] When the particulate aerosol generating article is in the suction 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 drops into the cavity 6 under the action of gravity, and the hollow cavity region of the hollow component 3 forms an air flow channel 7.

[0081] The bottom surface 52 of the seal has an opening 521, 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 when 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.

[0082] The side wall of the hollow member 3 has a ventilation hole 31 that radially penetrates the side wall. After the main body portion and the outer sleeve 5 axially move 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. The number of the ventilation holes 31 is one or more. In order 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. When not in suction, that is, during the transportation or storage of the aerosol generating article, the existence of this ventilation hole will allow air to enter the inside of 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 external air entering the inside of the aerosol generating article through this ventilation hole, 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 outside the main body portion, and the ventilation hole is 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 hole, 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 hole. At this time, external air can enter the inside of the aerosol generating article through the ventilation hole. In addition, the ventilation hole 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 hole is just completely exposed, it means that the suction state position is reached. At this time, the ventilation hole can also directly be used as an indication mark for the pulling-out distance, killing two birds with one stone.

[0083] The hollow member 3 is in two sections.

[0084] The clamping and sealing member 523 is selected from paper materials.

[0085] Such as Figures 5 - 8, this embodiment further includes an aerosol generating system for 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 accommodating cavity N2 located inside the aerosol generating appliance housing N1. A locking member N3 that matches with the protruding portion 522 is provided in the aerosol generating article accommodating cavity N2, and the locking member N3 is fixed to the outer sleeve 5 through the protruding portion 522;

[0086] The locking member N3 can move axially to drive the outer sleeve 5 to axially move relative to the main body portion of the aerosol generating article.

[0087] The locking member N3 includes a support rod N31 and a locking disk N32 located on the support rod N31. A notch N33 having the same shape as the protruding portion 522 is provided on the locking disk N32, and the support rod N31 can drive the locking disk N32 to rotate;

[0088] After the aerosol generating article is inserted into the aerosol generating article accommodating cavity N2, the notch N33 corresponds to the protruding portion 522 in position, so that the locking disk N32 passes through the protruding portion 522 and enters the inside of the outer sleeve 5. Further, the support rod N31 drives the locking disk N32 to rotate, and the notch N33 is misaligned with the protruding portion 522 in position. The locking disk 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.

[0089] The method for using the aerosol generating system is as follows:

[0090] 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; insert the aerosol generating article in the non-drawing state position into the aerosol generating article accommodating cavity N2, and the notch N33 corresponds to the protruding portion 522 in position, so that the locking disk N32 passes through the protruding portion 522 and enters the inside of the outer sleeve 5;

[0091] B. Activate the locking component N3. The support rod N31 drives the locking disk N32 to rotate. The notch N33 is misaligned with the protrusion 522. 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 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 face of the hollow component 3 and the bottom face 52 of the seal. 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 drops into the cavity 6 under the action of gravity. The hollow cavity area of the hollow component 3 forms an air flow channel 7, and the aerosol-generating article is in the suction state position;

[0092] 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.
