Description

Technical Field

[0001] The present invention belongs to the field of aerosol generating products, and in particular to the technical field of aerosol generating products using aerosol source material particles. Background Art

[0002] Particle-type aerosol generating products are a new type of heat-not-burn (Heat-Not-Burn, abbreviated as HNB) aerosol generating products in recent years. They use aerosol source material particles instead of aerosol source material sheets as aerosol generating materials. Aerosol source material particles are heated more evenly than aerosol source material sheets, and the aerosol diffuses more smoothly along the gaps between particles than along the gaps between sheet materials. Therefore, they are deeply loved by consumers.

[0003] Particulate aerosol generating products are known products on the market. Figure 1 The structure is described as follows: the main structure is an integrated outer sleeve 2, the distal lip end of which is sealed by a sealing film 1, and then aerosol source material particles 9 are filled into it to form a particle segment, and a multi-hole fastener segment (commonly known as a "gear component") 20 is provided downstream of the particle segment, and then a cavity segment 10 is reserved for collecting and accommodating aerosols (sometimes the side wall of the cavity segment 10 is also provided with air inlet holes to cool the aerosol, or sometimes the cavity segment is filled with cooling materials or flavoring materials to cool or flavor), and the downstream of the cavity segment 10 is a filter segment 4, which also serves as a cigarette holder for users to hold in their mouths. When the cigarette is used, the distal lip end is inserted into a heating device, and the heating device has a central heating element, which can pierce the sealing film 1 and insert into the particle segment to heat the particles to release gaseous aroma components, and the gaseous aroma components are condensed into aerosols visible to the naked eye when encountering cold air in the cavity segment 10, and then the aerosol is filtered by the filter segment and enters the user's mouth.

[0004] Among them, the cavity section 10 is crucial to the formation of aerosol. According to aerosol science theory, the gaseous aroma components released by heat need to be cooled to condense into solid particles or liquid particles, and the solid particles or liquid particles need to be suspended in the air to form an aerosol visible to the naked eye (commonly known as "smoke" or "fog" or generally referred to as "smog"). Therefore, in the existing particulate aerosol generating products, this cavity section must be retained.

[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 cavity section on a large scale, resulting in a significant reduction in the particles that can be directly heated by the inserted heating element, and the amount of flavor components released and the amount of aerosol generated subsequently 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 providing a sealing film 1 upstream of the particle section and a multi-hole firmware section 20 downstream of the particle section. The restraint at both ends prevents the particles from flowing everywhere.

[0006] The material of the multi-through hole firmware segment 20 is usually ceramic or silica gel, and its outer wall is firmly attached to the inner wall of the paper tube by an adhesive, and the center thereof has at least one axial through hole 6, and / or, the periphery thereof has at least one peripheral ventilation groove 7, and their sizes are all for smoke to pass through but do not allow aerosol source material particles to pass through, which not only blocks aerosol source material particles but also transmits smoke. In addition, when the resistance heating sheet or electromagnetic heating sheet is inserted into the particle segment for central heating, the multi-through hole firmware segment is firmly adhered to the inner wall of the paper tube, and can also prevent the aerosol source material particles from pushing the multi-through hole firmware segment itself to move downstream under the push of the heating sheet insertion force (because the filled particles have great resistance to the insertion of the heating sheet, the user needs to provide an insertion force to the heating sheet to insert it). However, the existence of the multi-through hole firmware segment has brought cost increase and many operational inconveniences to the industrialized manufacturing of particle-type 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, under the premise that there must be a cavity segment downstream of the particle segment, how to constrain the particles is a difficult problem.

[0007] The present invention aims to solve the above-mentioned problems. Summary of the invention

[0008] The first aspect of the present invention discloses a particle-type aerosol generating product that does not use a multi-hole firmware segment, which includes an outer sleeve 2, a sealing membrane 1 that seals the distal lip end of the outer sleeve 2, and an inner sleeve 3 inserted into the outer sleeve 2. The bottom of the inner sleeve 3 is sealed by a breakable sealing member 5. Downstream of the breakable sealing member 5 is a particle filling section filled with aerosol source material particles 9. The particle filling section has a filter section 4 downstream. The breakable sealing member 5 is axially separated from the sealing membrane 1 by a distance to form a native cavity section 8 between the two.

[0009] The upstream and downstream are determined according to the gas flow direction.

[0010] Preferably, the breakable sealing member 5 is a breakable sealing membrane, or is a compressed end of the particle segment.

[0011] Preferably, the breakable sealing member 5 blocks the entire distal lip end of the inner sleeve 3, which is applicable to a cylindrical inner sleeve, and more applicable to a truncated cone-shaped inner sleeve with a radial contraction at the bottom end; or, the distal lip end of the inner sleeve 3 has a bottom wall with a bottom through hole 31, and the breakable sealing member 5 blocks the bottom through hole 31, and the size of the bottom through hole 31 is larger than the size of the aerosol source material particles 9, so that the particles can leak from the bottom through hole into the primary cavity section 8. The scheme with a bottom through hole is more preferred because the bottom wall of the inner sleeve can largely prevent the particles from flowing back into the inner sleeve from the bottom through hole. If a heating element with a tip is used, that is, the top size of the heating element is smaller than the main body size, the heating element can be further pushed axially after the particles flow into the primary cavity so that the main body is located at the bottom through hole, and the gap between the two can further prevent the particles from flowing back into the inner sleeve. Similarly, if a truncated cone-shaped inner sleeve is used, the same particle backflow prevention effect is also achieved.

[0012] The filling amount of the particles can be designed according to actual needs. For example, the original cavity 10 can be just filled up while the internal space of the inner sleeve is emptied, which is the most preferred method. Of course, a portion of the particles can also remain inside the inner sleeve after the original space 10 is filled up.

[0013] The inner sleeve 3 can be fixed inside the outer sleeve 2 in any manner, for example, by adhesive or friction or the cooperation of the mechanical structure between the two.

[0014] Preferably, the outer sleeve 2 or the inner sleeve 3 is independently an integral paper sleeve.

[0015] Preferably, the filter section 4 is placed in the inner sleeve 3 or in the outer sleeve 2 .

[0016] Preferably, in a non-heating state, the filtering section 4 is located immediately downstream of the particle section. Of course, if necessary, a cavity can be left between the particle section and the filtering section 4.

[0017] The second aspect of the present invention discloses an aerosol generating device-aerosol generating product combination kit, which includes an aerosol generating device with a heating element and a particle-type aerosol generating product that does not use a multi-hole fastener segment, wherein the tip of the heating element has barbs, and the barbs are used to prevent particles from flowing back into the inner sleeve.

[0018] The third aspect of the present invention discloses a method for using the particle-type aerosol generating product without using a multi-hole firmware segment according to the first aspect of the present invention, which comprises the following steps: puncturing the sealing film 1 with a heating element and then puncturing the breakable sealing member 5, so that the aerosol source material particles 9 flow into the primary cavity segment 8 through the punctured portion and are heated by the heating element, and the space originally occupied by the aerosol source material particles 9 is vacated and a new cavity segment is formed in situ, which is used to condense the gaseous aroma components released by the aerosol source material particles 9 after being heated to form an aerosol, and the aerosol leaves the particle-type aerosol generating product after being filtered by the filter segment 4.

[0019] The sealing film 1 can act as an extractor to ensure that when the user pulls out the aerosol generating product after inhalation, the sealing film 1 holds all particles together with the aerosol generating product and is pulled out together with the aerosol generating product instead of being scattered in the aerosol generating device.

[0020] The above technical solutions can be freely combined under the premise of no contradiction.

[0021] The present invention has the following beneficial effects:

[0022] 1. The multi-through-hole firmware section is cancelled, but at the same time, the particles can still be constrained at both ends: in the storage state, the particles are constrained at both ends by the breakable sealing piece 5 on the inner sleeve (coordinated with the bottom wall of the inner sleeve when necessary) and the filtering section 4; in the working state, the particles are constrained at both ends by the gap between the sealing film 1 and the bottom wall of the inner sleeve or the heating element and the bottom through hole.

[0023] 2. The original particle-type aerosol generating product is a four-segment product (from the far lip end to the near lip end, it is the particle segment, the multi-hole hardware segment, the cavity segment and the filter segment in turn), and the four segments must be loaded in succession at the same work site, resulting in a long time spent on a single finished product. The present invention eliminates the multi-hole hardware segment, which first simplifies production, and the present invention can load the particle segment and the filter segment into the inner sleeve in advance at A, assemble them, and then transport them to B as independent prefabricated semi-finished products, and then insert the inner sleeve into the outer sleeve to obtain the finished product, wherein A can be at the same place or different places as B, and the division of labor will lead to a shorter time spent on a single finished product, improve production efficiency, and also facilitate manufacturers to outsource part of the work.

[0033] The content of the present invention is further explained below through specific implementation examples.

[0034] Example 1

[0035] like Figure 3 As shown, the particle-type aerosol generating product of the present invention which does not use a multi-hole firmware segment comprises an outer sleeve (2), a sealing film (1) sealing the distal lip end of the outer sleeve (2), and an inner sleeve (3) inserted into the outer sleeve (2), wherein the bottom wall of the inner sleeve (3) has a bottom through hole, which is sealed from the lower side of the through hole by a breakable sealing member (5) made of starch material, and downstream of the breakable sealing member (5) is a particle filling segment filled with aerosol source material particles (9), and downstream of the particle filling segment is a filtering segment (4), and the breakable sealing member (5) is axially separated from the sealing film (1) by a distance to form a native cavity segment (8) between the two.

[0036] Further Figure 4As shown, after the sealing film (1) is punctured by the heating element 11 and then the breakable sealing member (5) is broken, the aerosol source material particles (9) flow into the primary cavity section (8) through the punctured portion and fill the primary cavity section 8, and then are heated by the heating element, the space originally occupied by the aerosol source material particles (9) is vacated and a new cavity section (10) is formed in situ, which is used to condense the gaseous flavor components released by the aerosol source material particles (9) after being heated to form an aerosol, and then leave the particle-type aerosol generating product after being filtered by the filter section (4). Because the bottom wall of the inner sleeve can largely prevent the particles from flowing back into the inner sleeve from the bottom through hole.

[0037] The bottom wall of the inner sleeve can prevent the particles from flowing back into the inner sleeve; the heating element with a pointed tip can also further push the heating element axially after the particles have flowed into the primary cavity so that its main body is located at the bottom through hole, and the gap between the two can further prevent the particles from flowing back into the inner sleeve; the heating element can also be Figure 7 Shown with barbs; any one or a combination of these three factors helps prevent particles from flowing back into the inner sleeve.

[0038] Example 2

[0039] It is basically the same as the first embodiment, except that the breakable blocking member 5 is located at the bottom through hole. Figure 5 .

[0040] Example 3

[0041] The embodiment is basically the same as the first embodiment, except that the inner sleeve has an inner diameter contraction section, and the breakable plugging member 5 is a compressed particle plugging layer covering the entire lower end surface of the inner sleeve. Figure 6 The compacted particle blocking layer can withstand normal bumps without breaking, and after being punctured by the heating element, the lower end of the entire inner sleeve is opened to allow the particles to flow down.

[0042] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
