Detailed implementation manners
[0023] The present application will be further described in detail below in conjunction with the accompanying drawings through specific implementation manners. Similar elements in different implementation manners are labeled with related similar element numbers. In the following implementation manners, many detailed descriptions are provided to enable a better understanding of the present application. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification to avoid the core part of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the descriptions in the specification and general technical knowledge in the art.
[0024] In addition, the features, operations, or characteristics described in the specification can be combined in any appropriate manner to form various implementation manners. At the same time, the steps or actions in the method description can also be reordered or adjusted in an obvious manner for those skilled in the art. Therefore, the various sequences in the specification and drawings are only for clearly describing a certain embodiment and do not mean that they are necessary sequences, unless it is stated that a certain sequence must be followed.
[0025] The serial numbers assigned to components in this text itself, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meaning. And the "connection" and "coupling" mentioned in this application, unless otherwise specified, both include direct and indirect connection (coupling).
[0026] In the related art, there is a problem that residues remain after the use of an aerosol-generating article and the heated section of the aerosol-generating fuming section is unevenly heated. In this application, by horizontally arranging the first induction heating element on the substrate section, when heating is used, while heating the substrate section, it can also intercept the substances in the substrate section from leaking out of the aerosol-generating article to a certain extent; since the temperature of the first induction heating element is relatively high, even if substances such as condensate flow to the first induction heating element, they will be further heated to generate aerosol more, so the effect of significantly reducing residues can be achieved; further, a spacer section is arranged outside the first induction heating element, and after the aerosol-generating article is heated and used, its heated end face will not be directly exposed, thus avoiding scalding the user.
[0027] In one embodiment, as Figures 1 - 4 shown, an aerosol-generating article is provided, including a cylindrical housing 11, a substrate section 12, a heating element 13, etc.
[0028] The housing 11 has a first end 111 and a second end 112. The first end 111 is the end for the user to suck when sucking; the second end 112 is the end away from the user's sucking.
[0029] The substrate section 12 is arranged inside the housing 11. When the aerosol-generating article is heated, the fuming substances in the substrate section 12 are heated to generate aerosol for the user to suck.
[0030] The heating element 13 includes a heating element 131, and the heating element 131 includes a first induction heating element 1311; the first induction heating element 1311 is horizontally arranged on one end face of the substrate section 12 close to the second end 112. The first induction heating element 1311 can be horizontally arranged so as to perform surface heating on the substrate section 12. Herein, the horizontal direction in this embodiment is the direction substantially parallel to the end face of the substrate section 12, and the vertical direction is the direction substantially perpendicular to the end face of the substrate section 12.
[0031] In use, by placing the aerosol generating article in the heating device, the induction heating coil of the heating device generates a magnetic field to heat the first inductive heating element 1311. The heat generated by the first inductive heating element 1311 is transferred to the substrate section 12 to heat the substrate section 12 to generate aerosol. The entire contact surface of the substrate section 12 can be directly heated, and the substrate section 12 is heated more evenly, thus avoiding the defect of uneven heating of the substrate section 12 in the central heating mode of the prior art, and having the advantage of good heating effect. While heating the substrate section 12, it can also intercept the substances in the substrate section 12 from leaking out of the aerosol generating article to a certain extent; since the temperature of the first inductive heating element 1311 is relatively high, even if substances such as condensate flow to the first inductive heating element 1311, they will be further heated to generate aerosol more, so the effect of significantly reducing residues can be achieved.
[0032] Further, a spacer section 14 is provided on the outer side of the first inductive heating element 1311 near the second end 112. Through the arrangement of the spacer section 14, after the aerosol generating article is heated and used, its heated end face will not be directly exposed, thus causing scalding of the user.
[0033] In one embodiment, as Figure 1 shown, the spacer section 14 is a receiving space 141 provided on the upstream side of the housing 11. The receiving space 141 is open towards the second end 112, and the receiving space 141 extends from the second end 112 to the first inductive heating element 1311. The receiving space 141 makes the first inductive heating element 1311 retract into the housing 11, thus avoiding direct exposure, and thus playing a role in preventing the user from contacting the first inductive heating element 1311 and being scalded.
[0034] In one embodiment, the spacer section 14 includes a heat insulation section. The heat insulation section shields the side of the first inductive heating element 1311 facing the second end 112 to prevent the first inductive heating element 1311 from being exposed and directly contacting the user.
[0035] Exemplarily, as Figure 2 shown, the heat insulation section includes a heat insulation member 142. The heat insulation member 142 is connected to the housing 11 and seals the second end 112 or seals on the side of the first inductive heating element 1311 near the second end 112. Through the arrangement of the heat insulation member 142, the risk of the user directly contacting the magnetic induction heating member 13 can be further reduced, and the risk of being scalded can be further reduced.
[0036] It can be understood that a heat insulation member 142 can also be provided in the receiving space 141, and there is a certain distance between the side of the heat insulation member 142 near the second end 112 and the second end 112, further playing a role in preventing scalding.
[0037] Exemplarily, as Figure 3As shown, the heat insulation section includes a heat insulation layer 143 provided on the outer surface of the first induction heating element 1311. The heat insulation layer 143 can be a heat insulation film or other heat insulation materials attached to the outer wall surface of the first induction heating element 1311. Of course, the outer wall surface of the first induction heating element 1311 can be exposed on the second end face of the housing 11 or located inside the housing 11.
[0038] In one embodiment, the housing 11 is circular tubular, and the ratio of the height of the accommodation space 141 in the axial direction to the diameter of the accommodation space 141 is greater than or equal to 0.3:1.
[0039] In one embodiment, the heating element 13 further includes a heat conducting member 132. One end of the heat conducting member 132 is connected to the first induction heating element 1311, and the other end extends into the matrix section 12. In addition to directly heating the matrix section 12, part of the heat generated by the first induction heating element 1311 can also be transferred to the heat conducting body and introduced into the middle of the matrix section 12 by the heat conducting body, so as to increase the heat receiving area of the matrix section 12 and improve the aerosol generation speed.
[0040] In one embodiment, the heat conducting body is a strip-shaped heat conducting member 132 made of heat conducting material to transfer the heat of the heating body to the smoke generating section.
[0041] In some embodiments, the heat conducting member 132 is columnar, spiral or wavy; of course, its shape can be designed according to actual needs.
[0042] In some embodiments, the heat conducting body is made of one or several of graphite powder, graphene, boron nitride, alumina, carbon powder, and its heat conductivity is 1-500W / m.k. In some embodiments, when the aerosol generating article is heated in the induction heating magnetic field, the heating temperature of the first induction heating element 1311 is higher than the temperature of the heat conducting body, and the temperature difference range is 20-80°C.
[0043] In one embodiment, the first induction heating element 1311 is hermetically sealed on one side of the matrix section 12 close to the second end 112. In some embodiments, the first induction heating element 1311 can be a solid cylinder, sealed on one side of the matrix section 12, so that the first heating element, the first induction heating element 1311, seals the end face of the matrix section 12, so that the aerosol generated by the matrix section 12 can only flow in the direction of the first end 111 near the lip end; and it can better prevent the substances in the matrix section 12 from falling through the second end 112.
[0044] Further, a through first air inlet hole 113 is provided on the side wall of the housing 11. The first air inlet hole 113 is provided on a section of the side wall of the housing 11 between the first induction heating element 1311 and the first end 111. External air flow is introduced through the first air inlet hole 113 to carry out the aerosol generated by the matrix section 12.
[0045] In some embodiments, the first air inlet holes 113 include one or more and are located at the lower part of the matrix section 12. The opening size of a single first air inlet hole 113 is 0.05 - 3 mm. The shape of the first air inlet holes 113 can be one or more of a round hole, a square hole, an elliptical round hole, a polygonal opening, and an irregularly shaped opening. The opening size can correspond to the diameter of a round hole, the major diameter of an elliptical round hole, the maximum width of a polygonal opening or an irregularly shaped opening, etc.
[0046] In some embodiments, there can be multiple first air inlet holes 113, which are evenly distributed around the periphery of the matrix section 12, so as to make the air intake more uniform.
[0047] In one embodiment, as Figure 4 shown, a second air inlet hole 1314 that axially penetrates is formed in the first induction heating element 1311. During suction, the outside air flow can directly enter the matrix section 12 to quickly carry out the aerosol generated by the matrix section 12. It can be understood that the opening position of the second air inlet hole 1314 can be adjusted according to actual needs.
[0048] In one embodiment, as Figure 5 shown, the heating element 13 further includes at least one layer of second induction heating elements 1313 arranged in the matrix section 12. The second induction heating elements 1313 and the first induction heating element 1311 are arranged at intervals along the axial direction of the matrix section 12.
[0049] In some embodiments, when there are multiple layers of second induction heating elements 1313, the second induction heating elements 1313 of each layer are arranged at intervals along the axial direction of the matrix section 12.
[0050] By arranging one or more layers of second induction heating elements 1313, the multiple layers of second induction heating elements 1313 can heat the matrix section in different sections, and thus the matrix section 12 can be heated more evenly.
[0051] In some embodiments, a gap 114 can be formed between the second induction heating element 1313 and the inner wall of the housing 11 to form a channel for the air flow to pass through. Of course, the gap 114 and the ventilation holes 1312 can also be provided simultaneously. When the user sucks, the air flow entering from the first air inlet hole 113 or the second air inlet hole 1314 can flow through the gap or the ventilation holes 1312 to carry out the aerosol in the smoking section and reach the first end 111 for the user to inhale.
[0052] In one embodiment, the aerosol-generating article further comprises: a cooling section 16 and a filtering section 17 which are located on the downstream side of the substrate section 12 within the housing 11 and are arranged in sequence from the second end 112 to the first end 111. In some embodiments, the aerosol-generating article may further comprise a flavor-carrying section 15. In some embodiments, the housing 11 may be a paper tube wrapped around the periphery of the substrate section 12, the flavor-carrying section 15, the cooling section 16 and the filtering section 17, or may be a hollow cylinder made of other materials, such as plastics, silica gel, etc. The flavor-carrying section 15 is a structure containing a flavoring component, and the flavoring component can be aspirated together with the aerosol.
[0053] In one embodiment, as Figure 6 shown, the present application further provides an aerosol-generating system, comprising an aerosol-generating article 10 and an aerosol-generating device 20 for heating the aerosol-generating article. The aerosol-generating article is the aerosol-generating article of any one of the above embodiments.
[0054] The aerosol-generating device 20 may comprise an insertion space 21 for inserting the aerosol-generating article and an induction heating coil 22 provided on the periphery of the insertion space 21; the first induction heating element 1311 of the aerosol-generating article 10 is heated by the induction heating coil 22, and the fuming substance in the substrate section 12 is heated by the heating element 131 and the heat-conducting element 132 of the aerosol-generating article 10.
[0055] The above uses specific examples to elaborate on the present application, which is only for helping to understand the present application and is not intended to limit the present application. For those skilled in the technical field to which the present application pertains, several simple deductions, deformations or substitutions can also be made according to the idea of the present application.
