DETAILED DESCRIPTION

In order to facilitate the understanding of the present application, the present application is described in more detail below with reference to the accompanying drawings and specific implementation methods.

One embodiment of the present application provides a heated aerosol-generating article comprising a plurality of elements assembled in the form of a strip, capable of generating an aerosol when heated.

In an embodiment, a portion of the components of the assembled multi-component aerosol-generating article are reusable and a further portion of the components are replaceable consumables.

1 to 6 show schematic diagrams of an aerosol-generating article 1000 according to one embodiment; in this embodiment, the aerosol-generating article 1000 includes a reusable main body, and a filter element 1600 and an aerosol-generating substrate 1200 that are removably coupled to the main body as replaceable consumables.

Aerosol-generating substrate 1200 is used to describe a substrate that is capable of releasing volatile compounds when heated, which volatile compounds can form an aerosol. The aerosols described herein can be visible or invisible and can include vapors (e.g., fine particles of a substance that is in a gaseous state that is typically liquid or solid at room temperature) as well as droplets of gas and condensed vapor. Aerosol-generating substrate 1200 can include, for example, one or more of: powders, particles, pellets, fragments, strands, strips, or flakes containing one or more of: dried flowers or fragrant leaves, grass leaves, tobacco leaves, tobacco main veins, expanded tobacco, and homogenized tobacco. In an optional embodiment, aerosol-generating substrate 1200 includes a gathered sheet of wrinkled homogenized tobacco material; the gathered sheet of wrinkled homogenized tobacco material includes glycerin as an aerosol former.

Filter element 1600 is used to filter the aerosol before it is delivered to the user. In some embodiments, filter element 1600 comprises a conventional cellulose acetate or polypropylene tow filter having low filtration efficiency.

In some embodiments, the peripheral surfaces of the consumable aerosol generating substrate 1200 and/or filter element 1600 are wrapped and restrained by outer wrapping paper to prevent the materials therein from spreading or loosening.

In the embodiments shown in Figures 1 to 6 , the aerosol-generating article 1000 has an overall appearance of a longitudinally elongated cylindrical structure for the convenience of inhalation by a typical user. Alternatively, in other alternative embodiments, the aerosol-generating article 1000 may have a longitudinally elongated elliptical cylinder, square cylinder, polygonal cylinder, or the like.

In some embodiments, the appearance of the aerosol-generating article 1000 can mimic the appearance of a conventional smokable cigarette. The aerosol-generating article 1000 can have an outer diameter of approximately 5 mm to 12 mm (e.g., approximately 5 mm to 10 mm). The aerosol-generating article 1000 has an overall length of approximately 40 mm to 100 mm. In alternative embodiments, the aerosol-generating article 1000 has an overall length of approximately 45 mm to 55 mm.

1 to 6 , the reusable body of the aerosol-generating article 1000 comprises:

The aerosol-generating article 1000 has an upstream end 1110 and a downstream end 1120 that are opposite to each other, and the body is configured to extend between the upstream end 1110 and the downstream end 1120. As used herein, the terms 'upstream' and 'downstream' are used to describe the relative positions of elements, or portions of elements, of the aerosol-generating article 1000 with respect to the direction in which a user draws inhalation upon the aerosol-generating article 1000 during use. In use, downstream can be the direction in which the user draws inhalation, while upstream is the direction away from the user. Furthermore, upstream is the direction in which external air enters the aerosol-generating article 1000, and downstream is the direction in which the air flow containing the aerosol is discharged from the aerosol-generating article 1000. In use, the aerosol generated by heating within the aerosol-generating article 1000 exits the aerosol-generating article 1000 downstream and is transported to the user.

1 to 6 , the reusable body of the aerosol-generating article 1000 includes a tubular housing 1160 ; the tubular housing 1160 at least partially defines the outer surface of the body and encloses and confines a plurality of functional components located therein.

In this embodiment, tubular outer shell 1160 is not conventional cigarette paper; rather, it is made of a rigid material, resulting in a longer lifespan than conventional cigarette paper. Tubular outer shell 1160 is made of high-temperature-resistant ceramic, quartz glass, or a polymer plastic, such as at least one of PEEK, PI, PAI, PBI, PEI, PPS, or PA46. Tubular outer shell 1160 has a wall thickness of approximately 0.2-0.5 mm.

As shown in Figures 1 to 6 , the housing 1160 of the reusable body includes: a first accommodating cavity 1150 located at the upstream end 1110 and defined by the tubular housing 1160; the first accommodating cavity 1150 is configured to removably receive at least a portion of an aerosol-generating substrate 1200, which is a replaceable consumable; and as shown in Figures 1 to 6 , when the aerosol-generating substrate 1200 is received in the first accommodating cavity 1150, a portion of the aerosol-generating substrate 1200 extends out of the upstream end 1110;

The support element 1300 is located downstream of the first accommodating cavity 1150. The support element 1300 includes a first support portion 1310 and a second support portion 1320 arranged axially. The first support portion 1310 is adjacent to the first accommodating cavity 1150 and defines at least a portion of the boundary of the first accommodating cavity 1150.

The heating element 1400 extends upstream from the first support portion 1310 of the support element 1300 to the first receiving cavity 1150 . When the aerosol-generating substrate 1200 is received in the first receiving cavity 1150 , the heating element 1400 is at least partially inserted into the aerosol-generating substrate 1200 to heat the substrate.

The second accommodating chamber 1140 is located immediately downstream of the second supporting portion 1320 of the supporting element 1300; the second accommodating chamber 1140 is used to removably receive at least a portion of the filter element 1600, which is a replaceable consumable; and as shown in Figures 1 to 6, when the filter element 1600 is received in the second accommodating chamber 1140, a portion of the filter element 1600 extends out of the downstream end 1120.

When the aerosol-generating substrate 1200 is received in the first receiving cavity 1150, the aerosol-generating substrate 1200 is stopped against the first support portion 1310 of the support element 1300. Furthermore, when the filter element 1600 is received in the second receiving cavity 1140, the filter element 1600 is stopped against the second support portion 1320 of the support element 1300.

In some embodiments, support element 1300 is made of a rigid material, thereby ensuring a relatively long service life. Support element 1300 is made of high-temperature-resistant ceramic, quartz glass, or a polymer plastic; the polymer plastic may be at least one of PEEK, PI, PAI, PBI, PEI, PPS, or PA46. In some embodiments, support element 1300 is securely mounted within housing 10 and cannot be removed from housing 10.

As shown in Figures 1 to 6, the first support portion 1310 of the support element 1300 is permeable to airflow, thereby enabling aerosol to pass through the first support portion 1310 and be delivered downstream during inhalation. In some embodiments, the first support portion 1310 may include a porous body; the term "porous" is intended to encompass both inherently porous materials and substantially non-porous materials rendered porous or permeable by the provision of a plurality of pores. Porous materials must have pores of sufficient size to allow air to pass therethrough and be drawn through the porous body, as porous bodies have a high surface area to volume ratio.

In the embodiments shown in Figures 1 to 6, a plurality of air channels 1131 are arranged in the first support portion 1310 and extend axially therethrough. In this embodiment, the plurality of air channels 1131 extend straight along the axial direction of the first support portion 1310. Furthermore, the plurality of air channels 1131 penetrate the first support portion 1310 axially. The plurality of air channels 1131 may be formed as through-holes in the first support portion 1310 made of a dense material. In some embodiments, the cross-section of the air channels 1131 is circular. Alternatively, in other embodiments, the air channels 1131 may have various cross-sectional shapes, such as hexagonal, quadrilateral, or triangular.

In some embodiments, the plurality of air channels 1131 are arranged in an orderly fashion within the first support portion 1310. The air channels 1131 extend in a predetermined direction, rather than randomly. Furthermore, in some embodiments, the plurality of air channels 1131 are arranged in an array within the first support portion 1310. Furthermore, in some embodiments, aerosol can pass through the air channels 1131 and be discharged downstream, as indicated by arrow R1 in FIG. Furthermore, in some embodiments, the arrangement of the plurality of air channels 1131 within the first support portion 1310 gives the first support portion 1310 a honeycomb structure.

As shown in Figures 2 to 6, the plurality of air channels 1131 are substantially evenly distributed within the first support portion 1310. Alternatively, in some embodiments, the plurality of air channels 1131 are unevenly distributed within the first support portion 1310. For example, the number/density of the plurality of air channels 1131 in the central region of the first support portion 1310 may be less or greater than the number/distribution density near the outer regions. In an embodiment, corresponding to the cylindrical shape of the first support portion 1310, the central region of the first support portion 1310 may be substantially the region within a radial distance equal to 1/2 of the diameter from the center of the cross section; the outer regions may be the region surrounding the central region. "Distribution density" may be the number of air channels 1131 per unit area of the cross section, or the "distribution density" may be expressed as the volume occupied by the air channels 1131. For example, the distribution density of the air channels 1131 in the central region may be expressed as the volume of the air channels 1131 in the central region.

In some embodiments, the air channel 1131 has a relatively large diameter; for example, the diameter of the air channel 1131 is in the range of 0.01 mm-1.0 mm. In an optional embodiment, the diameter of the air channel 1131 is in the range of 0.01-0.5 mm, thereby allowing the aerosol to flow smoothly.

In some embodiments, the cross-sectional area or diameter of the air channel 1131 is basically constant and the same along the axial direction; or in some other variations, the cross-sectional area or diameter of the air channel 1131 is variable, for example, the cross-sectional area or diameter of at least part of the air channel 1131 gradually decreases in the direction approaching the upper end.

In some embodiments, the air channel 1131 is formed by laser perforation, machining, or the like in the first support portion 1310. For example, machining to form the air channel 1131 may include piercing the first support portion 1310 with a slender needle or drill bit to form the air channel 1131. In the embodiment shown in Figures 2 and 3, the first support portion 1310 has a length of approximately 3-10 mm.

As shown in Figures 1 to 6, the second support portion 1320 of the support element 1300 is hollow and tubular, defining a cooling cavity 1321 therein. This cooling cavity 1321 extends along the length of the second support portion 1320. The axially extending cooling cavity 1321 allows airflow through the second support portion 1320 to flow in a longitudinal direction without significant radial deviation. The second support portion 1320 can cool the temperature of the aerosol stream drawn through the second support portion 1320 by heat transfer. Aerosol components interact with the space within the second support portion 1320 and lose thermal energy. In some embodiments, the temperature of the aerosol stream may decrease by more than 10 degrees Celsius as it is drawn through the second support portion 1320. In some embodiments, the temperature of the aerosol stream may decrease by more than 25 degrees Celsius or more than 30 degrees Celsius as it is drawn through the second support portion 1320.

During use, the aerosol generated by the heated aerosol-generating substrate 1200 passes through the air channel 1131 and the cooling chamber 1321 in sequence, and is filtered by the filter element 1600 before being output.

As shown in Figures 1 to 6, air inlet holes 1130 are arranged at intervals along the circumferential direction on the shell 1100; avoidance holes 1322 opposite to the air inlet holes 1130 are arranged on the second supporting portion 1320 of the supporting element 1300; and thus, when the user inhales, external cold air can enter the cooling cavity 1321 through the air inlet holes 1130, mix with the hot aerosol, and thus form cooling.

In some embodiments, heating element 1400 is connected to first support portion 1310 of support element 1300. As shown in Figures 2 to 6, heating element 1400 is arranged in a sheet-like shape extending within first accommodating cavity 1150. Heating element 1400 and support element 1300 are connected as a whole and are inseparable from each other.

In some embodiments, the heating element 1400 can generate eddy currents in a changing magnetic field and generate heat, thereby heating the aerosol-generating substrate 1200 to produce an aerosol. The heating element 1400 is made of a receptive metal or alloy material that can be penetrated by a changing magnetic field and generate heat; the receptive metal or alloy can be, for example, at least one of iron or an iron alloy, nickel or a nickel alloy, cobalt or a cobalt alloy, graphite, ordinary carbon steel, stainless steel, ferritic stainless steel, and Permalloy.

As shown in FIG6 , heating element 1400 includes a first portion 1410 and a second portion 1420. First portion 1410 is inserted into or securely connected to support element 1300, thereby stably mounting and securing heating element 1400. Second portion 1420 extends or projects into first accommodating cavity 1150, allowing insertion into aerosol-generating substrate 1200 for heating. The width of first portion 1410 is smaller than the width of second portion 1420.

In some embodiments, the heating element 1400 has a length of approximately 5-15 mm. Furthermore, the heating element 1400 has a thickness of approximately 0.02-1 mm. Furthermore, the second portion 1420 of the heating element 1400 has a width of approximately 2-6 mm. In some embodiments, the width of the second portion 1420 of the heating element 1400 is between 40% and 90% of the diameter of the aerosol-generating substrate 1200 and/or the first receiving cavity 1150. For example, in some specific embodiments, the diameter of the aerosol-generating substrate 1200 and/or the first receiving cavity 1150 is 7.6 mm. The width of the second portion 1420 of the heating element 1400 is between 3-7 mm.

In other optional embodiments, the heating element 1400 is constructed as an annular heating sheet, heating net, heating film or coating and surrounds the first accommodating cavity 1150, or the space of the first accommodating cavity 1150 is defined by the heating element 1400. When the aerosol generating substrate 1200 is inserted into the first accommodating cavity 1150, the heating element 1400 surrounds the outer side of the aerosol generating substrate 1200.

FIG3 illustrates a schematic diagram of an aerosol-generating article 1000, according to one embodiment, being received within a heating device 100 and heated to generate an aerosol. As shown in FIG3 , the heating device 100 is configured to receive and heat the aerosol-generating article 1000, thereby causing the aerosol-generating substrate 1200 within the aerosol-generating article 1000 to generate an aerosol for inhalation by a user. As shown in FIG3 , when the aerosol-generating article 1000 is received within the heating device 100, the filter element 1600 of the aerosol-generating article 1000 is exposed outside the heating device 100, which facilitates inhalation by the user. Furthermore, when the aerosol-generating substrate 1200 of the aerosol-generating article 1000 is consumed, the user can remove the aerosol-generating article 1000 from the heating device 100 for replacement.

According to the embodiment shown in FIG3 , the overall appearance of the heating device 100 is substantially configured as a flat cylinder. The structure of the heating device 100 includes:

The housing 10 is hollow inside, thereby forming a space for assembling necessary functional components such as electronic devices; the housing 10 has a proximal end 110 and a distal end 120 opposite to each other along the length direction;

a receiving opening 111 located at the proximal end 110; in use, the aerosol-generating article 1000 can be at least partially received into the housing 10 through the receiving opening 111, or removed from the housing 10 through the receiving opening 111;

The support 20 at least partially surrounds or defines a chamber; the chamber is for receiving at least a portion of the aerosol generating article 1000 extending into the housing 10 through the receiving opening 111;

The air inlet channel 150 is located between the chamber and the air inlet 121 ; in use, the air inlet channel 150 provides a passage path from the air inlet 121 into the chamber/aerosol generating article 1000 , as shown by arrow R11 in FIG. 3 .

As shown in FIG3 , the heating device 100 further includes:

A battery cell 130 for power supply;

A circuit board 140 is provided with a circuit;

The induction coil 40 is arranged around the bracket 20; the induction coil 40 is electrically connected to the circuit board 140, and the circuit board 140 can provide an alternating current to generate a changing magnetic field, thereby inducing the heating element 1400 of the aerosol generating article 1000 to form eddy current heating, thereby heating the aerosol generating substrate 1130 to generate aerosol.

3 , when the aerosol-generating article 1000 is received in the chamber and/or the holder 20, the heating element 1400 is located within the induction coil 40. Furthermore, when the aerosol-generating article 1000 is received in the chamber and/or the holder 20, the heating element 1400 is inductively coupled to the induction coil 40. Thus, when the aerosol-generating article 1000 is received in the chamber and/or the holder 20, the heating element 1400 can be induced by the magnetic field generated by the induction coil 40 to generate eddy current heating, thereby heating the aerosol-generating substrate 1200.

As shown in Figures 7 and 8 , the reusable body of the aerosol-generating article 1000 can be adapted to accommodate consumables of various configurations or types. For example, in Figures 7 and 8 , after the used aerosol-generating substrate 1200 is removed, the user can receive an aerosol-generating substrate 1200a of another embodiment into the first receiving cavity 1150 of the reusable body for use. Specifically, in this embodiment, the aerosol-generating substrate 1200a includes:

The aerosol substrate portion 1210a and the plug 1220a are arranged axially. During use, the aerosol substrate portion 1210a is heated to generate an aerosol. The plug 1220a is used to provide a blockage or seal upstream of the aerosol substrate portion 1210a, thereby preventing the material of the aerosol substrate portion 1210a from escaping upstream or the generated aerosol/aerosol condensate from leaking upstream. The aerosol substrate portion 1210a and the plug 1220a of the aerosol-generating substrate 1200a are wrapped and secured by conventional outer wrapping paper to prevent them from separating.

In use, when the aerosol-generating substrate 1200a is received in the first receiving cavity 1150 of the main body, the heating element 1400 can be inserted into the aerosol substrate portion 1210a to heat it to generate an aerosol.

In an embodiment, the plug 1220a is permeable to air flow, so that during inhalation, air can pass through the plug 1220a and flow to the downstream aerosol matrix portion 1210a; for example, in some embodiments, the plug 1140 can include a porous material such as porous ceramic, cotton fiber, cellulose acetate, folded paper, etc.

It should be noted that the specification and drawings of this application provide preferred embodiments of the present application, but are not limited to the embodiments described in this specification. Furthermore, it is possible for a person skilled in the art to make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to this application.
