Description

Technical Field

[0001] The present invention belongs to the field of aerosol-generating articles, and more particularly to the technical field of aerosol-generating articles using aerosol source material particles, and more specifically relates to a middle-section particulate aerosol-generating article and a combination set including the same. 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 therein to form a particulate section. A multi-vent firmware section (commonly known as a "gear part") X4 is provided downstream of the particulate section, and then an air flow passage section X5 is left for collecting and accommodating the aerosol (sometimes the air flow passage section X5 is a separate cavity, or sometimes the air flow passage section X5 is a hollow rod). Downstream of the air flow passage 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 are condensed into visible aerosol in the air flow passage 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 passage 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 passage section X5 must be provided.

[0005] In addition, since the particles are loose and have fluidity, if not constrained, when the aerosol-generating article is placed horizontally or inverted, the particles will inevitably flow downstream to the air 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 released flavor components and the amount of aerosol generated subsequently 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, and then it is 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 special equipment for pasting the sealing film is required. 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. During subsequent production, the sealing film that seals the mouth of the aerosol-generating article comes off, causing the 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 heating cigarette is made by using a sealing film for sealing and filling particles. There are problems of low automation, low sealing success rate (and it is 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 pulled out of the aerosol-generating device, resulting in difficult cleaning of the aerosol-generating device.

[0007] The material of the multi-vent firmware section X4 is usually ceramic or silica gel. 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, thus blocking the aerosol source material particles and being able to transfer the flue gas. However, the existence of the multi-vent firmware section brings about an increase in cost and many operational inconveniences to the industrial manufacturing of particulate aerosol-generating articles. 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 an air 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 products are all located at the upstream of the aerosol generating products (the end face is only separated from the outside world by a thin sealing film). During transportation and storage, the aerosol source material particles are easily affected by the outside world. In addition, in order to ensure that the aerosol source material particles are more easily heated to generate aerosols during inhalation, and in order to better release the generated aerosols, the aerosol source material particles need to be stacked as loosely as possible and not too tightly. However, this will result in a larger contact area between the aerosol source material particles and the air during transportation and storage, thereby causing the loss of additives such as flavors, fragrances, or smoke-generating agents added to the aerosol source material particles.

[0009] Therefore, how to remove the sealing film and the multi-hole firmware section, and still complete the restraint of the scattered aerosol source material particles, and ensure that the generated aerosol can be smoothly delivered to the filtration section, and further, how to ensure that the aerosol source material particles are not at the upstream of the aerosol generating product during transportation and storage, is a problem that people are eager to solve.

[0010] The present invention aims to solve the above-mentioned problems. Summary of the invention

[0011] The present invention provides a mid-section particle type aerosol generating product, which comprises an outer tube 5, and a filter component 1, an aerosol source material particle component 2 and a sealing component 3 which are arranged in sequence from the proximal lip end to the distal lip end in the outer tube 5;

[0012] The upstream end face of the aerosol source material particle component 2 is axially spaced a certain distance from the upstream end face of the particle-type aerosol generating product, and the distance is formed by the end cavity 4 formed by the outer tube 5. The sealing component 3 is located in the end cavity 4 and can move axially in the end cavity 4.

[0013] The upstream and downstream mentioned in the present invention are determined by the gas flow direction. More specifically, the far lip end is the upstream, and the near lip end is the downstream.

[0014] In the present invention, the sequential arrangement is not limited to the two being closely connected, but is only a limitation on the order of precedence. That is to say, other forms of units can be inserted between any two of the filter component 1, the aerosol source material particle component 2 and the sealing component 3.

[0015] Preferably, when the particle-type aerosol generating product is in a non-inhalation state, the sealing component 3 is located at the downstream end of the end cavity 4, and the aerosol source material particle component 2 contains aerosol source material particles 21;

[0016] When the particle-type aerosol generating product is in the suction state, the sealing component 3 is located at the upstream end of the end cavity 4, and the aerosol source material particles 21 contained in the aerosol source material particle component 2 fall into the end cavity 4, and the area of the aerosol source material particle component 2 that contains the aerosol source material particles 21 forms an airflow channel 22.

[0017] That is to say, when the particle-type aerosol generating product of the present invention is in a non-inhalation state and an inhalation state, the aerosol source material particles and the sealing component 3 both have two positions. When in a non-inhalation state, the aerosol source material particles are located in the middle section of the aerosol generating product, and the sealing component 3 is also located at the most downstream of the end cavity 4 to block the downstream aerosol source material particles. When in the inhalation state, the sealing component 3 is pulled down and moved to the most upstream of the end cavity 4 (the upstream end face of the sealing component 3 is flush with the upstream end face of the end cavity 4). As the sealing component 3 is pulled down, the aerosol source material particles fall into the end cavity, but at this time the upstream end face is still blocked by the sealing component 3.

[0018] This ensures that during transportation and storage, the aerosol source material particles are located in the middle section, and the two ends are blocked by the filter component 1 and the sealing component 3. Furthermore, if the aerosol source particles are loaded into the hollow component, the aerosol source material particles can be loaded more tightly, and the contact area with the air is minimized, thereby ensuring better preservation of additives such as flavors, fragrances or smoke-generating agents added to the aerosol source material particles. During use, as the sealing component 3 moves, the aerosol source material particles fall into the end cavity. Since the diameter of the end cavity 4 is larger than the diameter of the hollow cavity of the hollow component, the particles will be relatively loose after falling here, which is conducive to the generation and release of aerosols. The heating element of a traditional aerosol generating device can be used to heat the aerosol source material particles to produce an aerosol that can be inhaled, and an air flow channel is formed at the place where the aerosol source material particles are originally accommodated, providing space for the flow and convergence of the aerosol.

[0019] Preferably, the sealing member 3 has a protrusion 33, and the sealing member 3 is controlled to move axially in the end cavity 4 by the protrusion 33. The protrusion 33 can be located at any position of the sealing member 3 as long as it is convenient for pulling, and the pulling action here can be completed by an aerosol generating device, or can be completed manually before using the suction. Of course, more preferably, the pulling action is completed by using the aerosol generating device mentioned later in the present invention.

[0020] The card-sealing component 3 has a frustum-shaped hollow structure, which has a top surface 31 and an opening 32 at the bottom surface. Since the card-sealing component 3 is frustum-shaped, the bottom diameter thereof is larger than the top diameter, and since it has no bottom surface (open at the bottom), there is no constraint of the bottom surface on the side close to the bottom surface, and it will naturally expand to both sides, thereby increasing the friction force at the contact between the card-sealing component 4 and the inner wall of the outer tube 5, and ensuring that the card-sealing component 3 is more firmly inside the outer tube 5.

[0021] More preferably, the protrusion 33 is located at the bottom surface position of the card-sealing component 3, and the locking component of the aerosol generating device used in cooperation therewith enters through the opening 32 and matches with the protrusion 33.

[0022] The particulate aerosol generating article in the middle section of the present invention does not limit the manufacturing process. It can be in the form of filling, that is, each component is filled into the outer tube 5 in sequence, or it can be in the form of composite wrapping, that is, each unit is arranged in sequence and then formed into the outer tube 5 by the way of wrapping and rolling. The material of the outer tube 5 is selected from but not limited to paper, ceramic, heat-resistant resin or clay.

[0023] At the other end of the aerosol generating article, the card-sealing component 3 is directly selected to restrain the aerosol source material particles. The card-sealing component 3 can be directly filled into the outer tube 5 in the form of filling or composite, without the need to prepare equipment for pasting the sealing film, and also avoiding the problem of the sealing film being not firmly pasted and falling off. In addition, since the card-sealing component 3 is frustum-shaped, the bottom diameter thereof is larger than the top diameter, and since it has no bottom surface (open at the bottom), there is no constraint of the bottom surface on the side close to the bottom surface, and it will naturally expand to both sides, thereby increasing the friction force at the contact between the card-sealing component 4 and the inner wall of the outer tube 5, and ensuring that the card-sealing component 3 is more firmly inside the outer tube 5.

[0024] Preferably, the card-sealing component 3 further includes a sleeve 34, the sleeve 34 is located outside the frustum-shaped hollow structure and inside the end cavity 4. Preferably, the axial length of the sleeve 34 is equal to the axial length of the end cavity 4. Preferably, the axial length of the sleeve 34 is equal to the axial length of the end cavity 4. The sleeve 34 can facilitate the filling or pouring of the card-sealing component 3, and also facilitate the limitation of the axial length of the end cavity 4.

[0025] Preferably, the aerosol source material particle component 2 includes a hollow component 23, and the hollow cavity of the hollow component 23 contains aerosol source material particles 21.

[0026] That is to say, the hollow component 23 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, and aerosol source material particles 21 are accommodated in the hollow region. For the structures of the hollow corrugated groove rod and the hollow tube with a gear structure, reference can be made to the patent application filed by the applicant with the application number 2021226872810 and the title of an aerosol generating article for filling type with a limiting member. 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.

[0027] The aerosol source material particle component 2 is one section or multiple sections, that is to say, it can be one section or multiple sections of the hollow component 23. More preferably, the aerosol source material particle component 2 includes multiple sections of the hollow component 23. Preferably, they are two sections of hollow components with different materials. More preferably, as shown in the embodiment, the upstream hollow component 23 is a hollow corrugated groove rod, and the downstream hollow component 23 near the lip end is a hollow acetate fiber rod, wherein the diameter of the hollow cavity of the hollow corrugated groove rod is smaller than the diameter of the hollow cavity of the hollow acetate fiber rod. In this way, the generated aerosol first passes through the hollow corrugated groove rod with a small cavity diameter, and then passes through the hollow acetate fiber rod with a large cavity diameter and enters the filter component. When the aerosol passes through the two ends of the hollow, due to the change in the cavity diameter, a Venturi effect will be generated, thereby improving the cooling effect on the aerosol. In addition, the groove holes on the circumferential side of the hollow corrugated groove rod can also allow the aerosol to flow through.

[0028] Preferably, the outer tube 5 is selected from a breathable material, such as breathable forming paper. At this time, ambient air can enter the outer tube 5 through the outer tube 5.

[0029] Preferably, the outer tube 5 wrapping the aerosol source material particle component 2 has first side ventilation holes 51, and the number of the first side ventilation holes 51 is one or more.

[0030] That is to say, the outer tube 5 can be a breathable material or an airtight material. When it is a breathable material, air can be introduced into the outer tube 5 through its own breathability. When it is an airtight material, air can be introduced into the outer tube 5 by punching holes in the outer tube 5. For example, as mentioned above, the outer tube 5 wrapping the aerosol source material particle component 2 has first side ventilation holes 51 to further supplement air, reduce the aerosol temperature, and increase the aerosol amount.

[0031] Preferably, the outer tube 5 has an indication mark on the outside, and the relative axial movement of the snap-on component 3 and the outer tube 5 to the suction state position can be judged through the indication mark;

[0032] Preferably, the card-sealing component 3 is selected from paper materials, polylactic acid sheets, cellulose acetate or high-temperature resistant materials, where high-temperature resistant means that it can withstand temperatures of 250 - 320 °C.

[0033] The second aspect of the present invention provides an aerosol generating device - aerosol generating article combination set, which includes the aerosol generating article described in the first aspect of the present invention and an aerosol generating device;

[0034] The aerosol generating device includes an aerosol generating device housing N1 and an aerosol generating article accommodation cavity N2 located within the aerosol generating device housing N1. The aerosol generating article accommodation cavity N2 has a locking component N3 that matches the protrusion 33;

[0035] The locking component N3 can move axially to drive the card-sealing component 3 to move axially within the end cavity 4.

[0036] Preferably, the locking component 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 protrusion 33, and the locking disk N32 can rotate relative to the card-sealing component 3;

[0037] After the aerosol generating article is inserted into the aerosol generating article accommodation cavity N2, the notch N33 corresponds to the position of the protrusion 33, so that the locking disk N32 passes through the protrusion 33 and enters the interior of the card-sealing component 3. Further, the locking disk N32 and the card-sealing component 3 rotate relative to each other, and the notch N33 is misaligned with the protrusion 33. The locking disk N32 fixes the card-sealing component 3 through the protrusion 33, so that the locking component N3 pulls the card-sealing component 3 to move axially within the end cavity 4 through the protrusion 33.

[0038] Preferably, the aerosol generating device housing N1 also has a locking start button. After the aerosol generating article is inserted into the aerosol generating article accommodation cavity 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 body part of the aerosol generating article until it reaches the suction state position.

[0039] The usage method of the described aerosol generating device - aerosol generating article combination set is as follows:

[0040] A. When the particulate aerosol generating article is in a non-suction state, the card-sealing component 3 is located at the downstream end of the end cavity 4, and the aerosol source material particle component 2 contains aerosol source material particles 21;

[0041] B. Insert the aerosol-generating article into the aerosol-generating device. The notch N33 of the aerosol-generating device corresponds to the position of the protrusion 33, so that the locking disc N32 passes through the protrusion 33 and enters the inside of the sealing component 3. Further, the locking disc N32 and the sealing component 3 perform a relative rotational movement, and the notch N33 is misaligned with the protrusion 33. The locking disc N32 fixes the sealing component 3 through the protrusion 33, so that the locking component N3 pulls the sealing component 3 to axially move in the end cavity 4 through the protrusion 33, and pulls the sealing component 3 to the upstream end of the end cavity 4. The aerosol source material particles 21 contained in the aerosol source material particle component 2 fall into the end cavity 4. The area where the aerosol source material particles 21 are contained in the aerosol source material particle component 2 forms an air flow channel 22. The aerosol-generating device starts a heating program to heat the aerosol source material particles 21 in the end cavity 4 to generate an aerosol for inhalation, and the particulate aerosol-generating article is in an inhalation state.

[0042] The aerosol-generating device and the aerosol-generating article also have marks that facilitate the alignment of the notch N33 and the protrusion 33, so that consumers can directly determine the positions of the aerosol-generating article and the aerosol-generating device when inserting the aerosol-generating article, and ensure that the notch N33 and the protrusion 33 are directly aligned after the aerosol-generating article is inserted.

[0043] 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 generating heat by the heating element can be electromagnetic heating or resistance heating.

[0044] The aerosol-generating article of the present invention is more preferably applicable to a circumferential resistance heating aerosol-generating device and an electromagnetic heating aerosol-generating device. When the aerosol-generating device used in conjunction with it is a circumferential resistance heating aerosol-generating device, it is only necessary to axially position the heating cylinder (heating element) outside the aerosol source material particles 3. When the aerosol-generating device used in conjunction with it is an electromagnetic heating aerosol-generating device, it is only necessary to axially position the receptor capable of receiving a magnetic field outside the aerosol source material particles 3, or set it to the aerosol source material particles 3, or more simply, directly set the receptor material on the outer tube 5 wrapping the aerosol source material particles 3.

[0045] The above technical solutions can be freely combined on the premise of not being contradictory.

[0046] The present invention has the following beneficial effects:

[0047] 1. In the aerosol-generating article of the present invention, the multi-vented firmware section and the sealing film are eliminated. However, the filter component 1 and the snap-sealing component 3 can still restrict the particles at both ends. For the first time in the present invention, the aerosol source material particles are placed in the middle section of the aerosol-generating article. When sucking, the snap-sealing component 3 is controlled, and the aerosol source material particles naturally fall to the end under the action of gravity, and an air flow channel is formed downstream of the aerosol source material particles. On the one hand, the restriction of the aerosol source material particles at both ends is achieved without using the multi-vented firmware section and the sealing film. On the other hand, it also ensures an air flow channel for converging the aerosol downstream of the aerosol source material particles during sucking.

[0048] 2. Fixing the aerosol source material particles to the middle section of the aerosol-generating article during transportation and storage can also ensure better preservation of the flavoring agents added to the aerosol source material particles and avoid the influence of the outside world on the aerosol source material particles at the end. Further, if the aerosol source particles are filled into the hollow component, the aerosol source material particles can be filled more tightly, with the least contact area with air, thereby ensuring better preservation of the flavoring agents or additives such as smoke agents added to the aerosol source material particles. During use, as the snap-sealing component 3 moves, the aerosol source material particles fall into the end cavity. Since the diameter of the end cavity 4 is larger than the diameter of the hollow cavity of the hollow component, the particles will be relatively looser after falling here, which is conducive to the generation and release of the aerosol.

[0049] 3. Since the snap-sealing component 3 is frustum-shaped, its bottom diameter is larger than the top diameter. And because it has no bottom surface (open at the bottom), there is no restraint on the bottom surface on the side close to the bottom, so it will naturally expand to both sides, thereby increasing the friction force at the contact between the snap-sealing component 4 and the inner wall of the outer tube 5 and ensuring that the snap-sealing component 3 is more firmly inside the outer tube 5.

[0050] 4. The outer tube 5 can be a breathable material or an airtight material. When it is a breathable material, air can be introduced into the outer tube 5 through its own breathability. When it is an airtight material, air can be introduced into the outer tube 5 by punching holes in the outer tube 5. For example, as mentioned above, the outer tube 5 has first-side ventilation holes 51 at the part wrapping the aerosol source material particle component 2 to further supplement air, reduce the aerosol temperature and increase the aerosol amount.

[0051] 5. During the specific use process, the aerosol-generating device used in conjunction with the aerosol-generating article can also have an action of pushing the snap-sealing component 3 downstream after the sucking ends, which can further play a role in cleaning the heating element of the device, ensuring that the heating cavity of the aerosol-generating device is cleaner after the aerosol-generating article is pulled out and no aerosol source material particles will fall.

[0052] 6. 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 cylinder (heating element) axially outside the aerosol source material particles 3. When the aerosol generating device used in conjunction with it is an electromagnetic heating aerosol generating device, it is only necessary to position the receptor that can receive the magnetic field axially outside the aerosol source material particles 3, or to set it to the aerosol source material particles 3, or more simply to directly set the receptor material on the outer tube 5 that wraps the aerosol source material particles 3. The present invention greatly improves production efficiency. The use of circumferential heating or electromagnetic heating can avoid particles from scattering into the aerosol generating device and avoid the problem of cleaning the aerosol generating device.

[0053] 7. The locking component N3 of the aerosol generating device of the present invention and the sealing component 3 of the aerosol generating product can rotate relative to each other to fix the sealing component 3; further, the locking component N3 of the aerosol generating device can move axially to drive the sealing component 3 to move axially relative to the main body of the aerosol generating product, thereby realizing the function of locking the sealing component 3 and pulling the sealing component 3 out of the end cavity 4.

Example 1

[0076] As Figures 3 - 4 shown, in this embodiment, the segmented particulate aerosol generating article includes an outer tube 5, and a filter component 1, an aerosol source material particulate component 2, and a caulking component 3 arranged in sequence from the proximal lip end to the distal lip end inside the outer tube 5; the upstream end face of the aerosol source material particulate component 2 has a certain distance axially from the upstream end face of the particulate aerosol generating article, and this distance forms an end cavity 4 by the outer tube 5, the caulking component 3 is located in the end cavity 4 and can axially move in the end cavity 4.

[0077] When the particulate aerosol-generating article is in the non-drawing state position, the sealing member 3 is located at the downstream end of the end cavity 4, and the aerosol source material particle member 2 contains aerosol source material particles 21;

[0078] When the particulate aerosol-generating article is in the drawing state position, the sealing member 3 is located at the upstream end of the end cavity 4, and the aerosol source material particles 21 contained in the aerosol source material particle member 2 fall into the end cavity 4, and an air flow channel 22 is formed in the area where the aerosol source material particle member 2 contains the aerosol source material particles 21.

[0079] 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 sealing member 3 have two positions. When in the non-drawing state, the aerosol source material particles are located in the middle section of the aerosol-generating article, and the sealing member 3 is also located at the most downstream of the end cavity 4 to block the aerosol source material particles downstream. When in the drawing state, the sealing member 3 is pulled down and moves to the most upstream of the end cavity 4 (the upstream end face of the sealing member 3 is flush with the upstream end face of the end cavity 4). As the sealing member 3 is pulled down, the aerosol source material particles fall into the end cavity, but at this time the upstream end face is still blocked by the sealing member 3.

[0080] This ensures that during transportation and storage, the aerosol source material particles are located in the middle section, and both ends are blocked by the filter member 1 and the sealing member 3. During use, as the sealing member 3 moves, the aerosol source material particles fall into the end cavity, and the heating element of a traditional aerosol-generating device can be used to heat the aerosol source material particles to generate an aerosol for inhalation. An air flow channel is formed at the place where the aerosol source material particles were originally contained, providing space for the flow and convergence of the aerosol.

[0081] As Figure 5 shown, the sealing member 3 has a protrusion 33, and the axial movement of the sealing member 3 in the end cavity 4 is controlled by the protrusion 33. The sealing member 3 is a frustum-shaped hollow structure, which has a top surface 31 and an opening 32 at the bottom surface. The protrusion 33 is located at the bottom surface position of the sealing member 3, and the locking member of the aerosol-generating device used in cooperation enters through the opening 32 and matches with the protrusion 33. Among them, the top surface 31 faces the side near the lip end.

[0082] Furthermore, as Figure 6 shown, the sealing member 3 further includes a sleeve 34, and the sleeve 34 is located outside the frustum-shaped hollow structure and is located in the end cavity 4. The axial length of the sleeve 34 is equal to the axial length of the end cavity 4.

[0083] The aerosol source material particle component 2 includes a section of hollow component 23, and aerosol source material particles 21 are accommodated in the hollow cavity of the hollow component 23. Additionally, there are two first side circulation air holes 51 on the outer tube 5 wrapping the aerosol source material particle component 2.

[0084] The caulking component 3 is selected from paper materials.

[0085] Such as Figures 7 - 10 , an aerosol generating device - aerosol generating article combination set, the aerosol generating device includes an aerosol generating device housing N1 and an aerosol generating article accommodating cavity N2 located inside the aerosol generating device housing N1, and a locking component N3 matching the protrusion 33 is provided in the aerosol generating article accommodating cavity N2;

[0086] The locking component N3 can move axially to drive the caulking component 3 to move axially in the end cavity 4.

[0087] The locking component 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 protrusion 33, and the locking disk N32 can rotate relative to the caulking component 3;

[0088] After the aerosol generating article is inserted into the aerosol generating article accommodating cavity N2, the notch N33 corresponds to the position of the protrusion 33, so that the locking disk N32 passes through the protrusion 33 and enters the inside of the caulking component 3. Further, the locking disk N32 and the caulking component 3 rotate relative to each other, and the notch N33 and the protrusion 33 are misaligned in position. The locking disk N32 fixes the caulking component 3 through the protrusion 33, so that the locking component N3 pulls the caulking component 3 to move axially in the end cavity 4 through the protrusion 33.

[0089] The usage method of the aerosol generating device - aerosol generating article combination set is as follows:

[0090] A. When the particulate aerosol generating article is in a non-puffing state, the caulking component 3 is located at the downstream end of the end cavity 4, and the aerosol source material particle component 2 contains aerosol source material particles 21;

[0091] B. Insert the aerosol-generating article into the aerosol-generating appliance. The notch N33 of the aerosol-generating appliance corresponds to the position of the protrusion 33, so that the locking disc N32 passes through the protrusion 33 and enters the inside of the sealing member 3. Further, the locking disc N32 and the sealing member 3 perform a relative rotational movement, and the notch N33 is misaligned with the protrusion 33. The locking disc N32 fixes the sealing member 3 through the protrusion 33, so that the locking member N3 pulls the sealing member 3 to axially move in the end cavity 4 through the protrusion 33, and pulls the sealing member 3 to the upstream end of the end cavity 4. The aerosol source material particles 21 contained in the aerosol source material particle member 2 fall into the end cavity 4. The area in the aerosol source material particle member 2 that contains the aerosol source material particles 21 forms an air flow channel 22. The aerosol-generating appliance starts a heating program to heat the aerosol source material particles 21 in the end cavity 4 to generate an aerosol for inhalation, and the particulate aerosol-generating article is in an inhalation state. Example 2

[0092] As Figure 11 shown, the difference between the particulate aerosol-generating article in this example and that in Example 1 is that:

[0093] The particulate aerosol-generating article includes two sections of hollow members 23, and the hollow cavities of each section of the hollow member 23 contain aerosol source material particles 21. The hollow member 23 near the upstream is a hollow corrugated groove rod, and the hollow member 23 near the downstream, i.e., the lip end, is a hollow acetate fiber rod. The diameter of the hollow cavity of the hollow corrugated groove rod is smaller than the diameter of the hollow cavity of the hollow acetate fiber rod. The aerosol generated in this way first passes through the hollow corrugated groove rod with a small cavity diameter, and then passes through the hollow acetate fiber rod with a large cavity diameter and enters the filter member. When the aerosol passes through the two ends of the hollow, due to the change in the cavity diameter, a Venturi effect will be generated, thereby improving the cooling effect on the aerosol. In addition, the groove holes on the periphery of the hollow corrugated groove rod can also allow the aerosol to flow through. The outer tube 5 is selected from a breathable material, such as breathable forming paper. At this time, ambient air can enter the inside of the outer tube 5 through the outer tube 5.
