Abstract
Description
- The present disclosure belongs to the technical field of aerosol generating product, and in particular, to an aerosol generating product by using aerosol source-material granules.
- Aerosol granular generating products are a new type of Heat-Not-Burn (HNB) aerosol generating products in recent years, using aerosol source-material granules instead of aerosol source-material flakes as aerosol generating materials, as aerosol source-material granules are heated more evenly than aerosol source-material flakes, and aerosols diffuse more smoothly along the gap among granules than that among flake materials, they are deeply welcomed by consumers.
- Granular aerosol generating products are known on the market, the structure is illustrated with reference to
FIG. 1 : the main structure is an integratedouter sleeve 2, the distal lip is sealed by thesealing film 1, which is filled with aerosol source-material granule 9 to form the granule section, a multi-hole firmware section (commonly known as "gear") 20 is set in the downstream of the granule section, and acavity section 10 is set aside for collecting and accommodating aerosol (either the side walls of thecavity section 10 are also provided with air entry holes to cool the aerosol, or the cavity section is filled with cooling or flavoring materials to cool or flavor), the downstream of thecavity section 10 is afiltering section 4, which is also used as a cigarette holder for users to take in the mouth. When smoking cigarettes, the distal lip end is inserted into the heating appliance, the heating appliance has a central heating element to release gaseous aroma components by heating granules after piercing thesealing film 1 and inserting into the interior of the granule section, gaseous aroma components in thecavity section 10 are condensed into visible aerosol by cold air, and the aerosol is filtered in the filtering section and enters users' mouths. - Wherein, the
cavity section 10 is crucial for aerosol formation, according to scientific theories of aerosol, gaseous aroma components released by heat need to be cooled and condense into solid or liquid granules, such solid or liquid granules need to be suspended in the air to form visible aerosol (commonly known as "smoke" or "fog" or generally known as "smog"). Thus, the cavity section must be left in the existing granular aerosol generating products. - Besides, as granules are loose and fluid, if not constrained, such granules may inevitably flow to the downstream of the cavity section on a large scale when the aerosol generating products are placed horizontally or inverted, resulting in the fact that granules that can be directly heated by the heating element greatly decrease, the amount of aroma components and subsequent aerosol released may decrease; in order to ensure that granules are fully heated, such granules must be confined in a limited space near the heating element. Such constraint is currently achieved by setting a
sealing film 1 in the upstream of the granule section and providing amulti-hole firmware section 20 in the downstream of the particle section, so that granules may not flow everywhere with constraints at both ends. - Wherein the
multi-hole firmware section 20 is usually made of ceramic or silica gel, the outer wall is firmly bonded to the inner wall of the paper tube by adhesive, there is at least one axial through-hole 6 in the center and/or at least oneperipheral ventilation groove 7 on the periphery, their sizes can allow smog while not allowing aerosol source-material granules to pass through; thus, blocking aerosol source-material granules and transmitting flue gas can be realized. In addition, when inserting a resistance heating sheet or an electromagnetic heating sheet into the granule section for central heating, as the multi-hole firmware section is firmly adhered to the inner wall of the paper tube, it can also prevent aerosol source material granules from pushing the multi-hole firmware section downstream with the insertion force of the heating sheet (since the filled granules have great resistance to insertion of the heating sheet, users need to exert an insertion force to the heating sheet to insert). However, existence of a multi-hole firmware section brings more costs and operational inconveniences to industrial manufacturing of granular aerosol generating products, thus, those skilled in the art have been hoping to eliminate the multi-hole firmware section. However, once eliminating the multi-hole firmware section, granule constraint is a problem under the premise that there must be a cavity section in the downstream of the granule section. - The present disclosure aims to solve the problems above.
- A first aspect of the present disclosure discloses a granular aerosol generating product without using a multi-hole firmware section, including an
outer sleeve 2, asealing film 1 that plugs the distal lip end of theouter sleeve 2, and an inner sleeve inserted into theouter sleeve 2, the bottom of theinner sleeve 3 is sealed by thebreakable plugging part 5, and the downstream of thebreakable plugging part 5 is a granule filling section filled with aerosol source-material granule 9, afiltering section 4 is provided in the downstream of the granule filling section, and there is a distance between thebreakable plugging part 5 and thesealing film 1 in the axial direction to form anoriginal cavity section 8. - Wherein, the upstream and downstream are determined by the direction of gas flow.
- Preferably, the
breakable plugging part 5 is a breakable plugging film or a compressed end of the granule section. - Preferably, the whole distal lip end of the
inner sleeve 3 is plugged by thebreakable plugging part 5, which is suitable for cylindrical inner sleeves, and more suitable for round-shaped inner sleeves radially contracted at the bottom; or, the distal lip end of theinner sleeve 3 has a bottom wall with a bottom through-hole 31, and the breakable pluggingpart 5 plugs the bottom through-hole 31, the size of the bottom through-hole 31 is larger than that of the aerosol source-material granule 9, so that granules leak from the bottom through-hole into theoriginal cavity section 8. The technical solution with a bottom through-hole is more preferred, since the bottom wall of the inner sleeve can largely prevent backflow of granules from the bottom through-hole into the inner sleeve. In case a heating element with a tip is used, that is, the top size of the heating element is smaller than that of the main part, the heating element can be further pushed in the axial direction after all granules flow into the original cavity, so that the main part of the heating element is located at the bottom through-hole, the gap between the two can further prevent backflow of granules into the inner sleeve. Similarly, in case the round-shaped inner sleeve is used, the same effect can be achieved. - The filling amount of granules can be designed according to actual needs, e.g., most preferably, granules can be filled in the
original cavity 10 and emptying the inner space of the inner sleeve; certainly, granules can also be left inside the inner sleeve after being filled in theoriginal cavity 10. - The
inner sleeve 3 can be fixed inside theouter sleeve 2 in any way, e.g., it can be fixed inside theouter sleeve 2 by adhesive or friction or through mechanical-structure coordination between them. - Preferably, the
outer sleeve 2 or theinner sleeve 3 is an independently integral paper tube. - Preferably, the
filtering section 4 is disposed inside theinner sleeve 3 or theouter sleeve 2. - Preferably, in an unheated state, the
filtering section 4 is located immediately downstream of thegranule section 3. Certainly, if necessary, an additional cavity can also be left between thegranule section 3 and thefiltering section 4. - A second aspect of the present disclosure discloses an aerosol generating appliance-aerosol generating product set, including an aerosol generating appliance with a heating element and a granular aerosol generating product without using a multi-hole firmware section, the heating element has a barb at the tip to prevent granules from backflowing into the inner sleeve.
- A third aspect of the present disclosure discloses a method for using the granular aerosol generating product without a multi-hole firmware section in the first aspect of the present disclosure, including the following steps: pierce the
sealing film 1 with a heating element and pierce thebreakable plugging part 5, so that the aerosol source-material granule 9 is heated by the heating element after flowing into theoriginal cavity section 8 through the pierced point, the space originally occupied by the aerosol source-material granule 9 is emptied out to form a new cavity section in situ, which is used to condense gaseous aroma components released by the aerosol source-material granule 9 after being heated to form aerosol, and leaves the granular aerosol generating product after being filtered in thefiltering section 4. - The sealing
film 1 can act as an extractor to ensure that when users pull out the aerosol generating product after smoking, the sealingfilm 1 holds all granules together to pull out with the aerosol generating product instead of scattering inside the aerosol generating appliance. - The technical solutions can be combined freely without contradiction.
- The present disclosure has the following beneficial effects:
- 1. The multi-hole firmware section is eliminated, while granules can still be constrained at both ends: during storage, granules are constrained at both ends by the
breakable plugging part 5 on the inner sleeve (if necessary, coordinating with the bottom wall of the inner sleeve) and thefiltering section 4; while in the working state, both ends of granules are constrained by the gap between thesealing film 1 and the bottom wall of the inner sleeve or that between the heating element and the bottom through-hole. - 2. The original granular aerosol generating product has four-sections (from the distal to the proximal lip end: the granule section, the multi-hole firmware section, the cavity section and the filtering section), it is necessary to fill the four sections in the same work site successively, resulting in longer working hours for a single finished product. While the present disclosure not only simplifies production by eliminating the multi-hole firmware section, but fill the granule section and the filtering section into the inner sleeve in place A and assemble them as independent prefabricated semi-finished products and transport to place B, the inner sleeve is inserted into the outer sleeve to obtain finished products, wherein, place A and place B can be same or different, such labor division will result in shorter working hours for a single finished product and higher production efficiency, and manufacturers can outsource part of their work.
