Technical Field

The present application relates to the field of aerosol generating technology, in particular to an aerosol generating article.

Background

As is known in the art, aerosol-generating substrates in aerosol-generating articles are capable of releasing volatile compounds that can form an aerosol that is intended to meet the needs of a user for smoking. The aerosol generating product is close to the traditional cigarette in the aspects of smoking mode, smoking experience and the like, and the release amount of harmful ingredients is small, so that the aerosol generating product has great development potential in the tobacco market.

Currently, in some aerosol generating products, aroma releasing particles with different flavors are added in the flowing process of the aerosol, and the flavor medium released by the aroma releasing particles is mixed after the aerosol contacts with the aroma releasing particles so as to adjust the flavor of the aerosol. However, in the existing aerosol-generating product, the fragrance-releasing particles are easy to permeate due to long-term contact with a paper tube of the aerosol-generating product, the service time of the fragrance-releasing particles is reduced, and the flavor substances released by the fragrance-releasing particles are not in sufficient contact with the aerosol flowing through, so that the smoking taste of a user is influenced.

SUMMERY OF THE UTILITY MODEL

In some possible embodiments, the aerosol-generating article further comprises an aerosol-generating substrate portion, the second end of the capsule abutting the aerosol-generating substrate portion.

In some possible embodiments, the side wall of the capsule is in close proximity to the inner wall of the tubular body.

In some possible embodiments, the capsule comprises a first shell and a second shell connected.

The beneficial effect of this application is: the application provides an aerosol generates goods, including the body, is provided with the capsule in the body, and the capsule intussuseption is filled with the fragrance releasing granule, and the capsule includes along the first end of body axial setting and the second end relative with first end, and the first through-hole region that a plurality of through-holes formed is seted up to first end, and the second through-hole region that a plurality of through-holes formed is seted up to the second end.

Detailed Description

Reference will now be made in detail to the embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application.

As shown in fig. 1, an aerosol-generating article 100 is provided in an embodiment, which may be used in an aerosol-generating device. Wherein the aerosol-generating device may be of the heated non-combustible type.

As shown in fig. 1 and 2, the aerosol-generating article 100 may comprise a capsule 10, flavour-releasing particles 20 and a tube 30. Wherein the capsule 10 can be disposed in the tube 30. The body 30 may be formed from a paper material such as tipping paper, wood grain paper, or any suitable material or combination of materials. In some cases, tube 30 may also be formed from materials such as metal foil, metal foil composite paper, grease-proof paper, ceramics, carbon allotropes (e.g., graphite and graphene), plastics, wood, or combinations thereof.

As shown in FIG. 2, the interior of the capsule 10 is hollow and may form a cavity 103. The fragrance-releasing particles 20 may be contained in the cavity 103. It is understood that the scent-releasing particles 20 can include carrier particles and a flavoring agent. Wherein the carrier particles may be particles having a porous structure, and the flavor medium may be adsorbed in the carrier particles.

As shown in fig. 2 and 4, the capsule 10 may be made of a non-hydrophilic material such as Polypropylene (PP) plastic, polyvinyl Chloride (PVC) plastic, or Polyethylene (PE) plastic. Thus, the capsule 10 provides a protection function for the fragrance-releasing particles 20, preventing the fragrance-releasing particles 20 from directly contacting the tube 30. When the aerosol-generating article 100 is not in use, permeation of the flavor medium in the flavor-releasing particles 20 into the surrounding environment can be reduced, loss of the flavor medium in the flavor-releasing particles 20 can be reduced, the failure rate of the flavor-releasing particles 20 can be delayed, and the shelf life of the flavor-releasing particles 20 can be prolonged.

In some embodiments, capsule 10 may include a first shell 11 and a second shell 12. The first housing 11 and the second housing 12 may cooperate to define a cavity 103. The ends of the first shell 11 and the second shell 12 close to each other may be fixedly connected by means of adhesion, screw connection, or heat fusion. And, the first shell 11 and the second shell 12 are connected in a sealing way, so that the aerosol can be prevented from leaking from the assembly gap of the first shell 11 and the second shell 12, and the possibility of the odor medium in the aroma releasing particles 20 permeating outwards can also be reduced.

Referring again to fig. 4-8, capsule 10 may include a first end 101 and a second end 102 opposite first end 101. In some embodiments, the end of the first housing 11 distal to the second housing 12 may serve as the first end 101 of the capsule 10. The end of the second housing 12 remote from the first housing 11 may serve as the second end 102 of the capsule 10.

The first end 101 may be formed with a first via region 111 formed by a plurality of vias, and the vias of the first via region 111 may be referred to as a first via 1111. The second end 102 may be formed with a second via area 121 formed by a plurality of through holes, and the through holes in the second via area 121 may be referred to as a second via 1211. It can be understood that the first through hole 1111 and the second through hole 1211 are both communicated with the cavity 103, and the aperture of the first through hole 1111 and the aperture of the second through hole 1211 are both smaller than the diameter of the fragrance-releasing particle 20.

With reference to fig. 2, 3 and 9, in some embodiments, an orthogonal projection of the first through-hole region 111 perpendicular to the axial direction of the pipe body 30 may not overlap or only partially overlap an orthogonal projection of the second through-hole region 121 perpendicular to the axial direction of the pipe body 30. The axial direction of the tube 30 can refer to the extending direction of the central axis L, and in the embodiment, the central axis of the capsule 10 can coincide with the central axis L of the tube 30.

During use of the aerosol-generating article 100, when a user draws in, the cavity 103 of the capsule 10 may be evacuated, and the aerosol may enter the cavity 103 from the second through-hole region 121 under the negative pressure, thereby, the aroma-releasing particles 20 may be urged to tumble in the cavity 103 to release the flavor medium.

In addition, in the present application, an orthogonal projection of the first through hole region 111 perpendicular to the axial direction of the pipe body 30 and an orthogonal projection of the second through hole region 121 perpendicular to the pipe body 30 do not overlap or partially overlap. Therefore, when the aerosol enters the cavity 103 and moves from the end close to the second through hole area 121 to the end close to the first through hole area 111, the moving path of the aerosol is inclined with respect to the axial direction of the tube 30. Compared with the mode of moving along the axial direction of the tube body 30, the aerosol can be prolonged in the flow path and the passing time of the aerosol in the cavity 103, so that the aerosol can be fully contacted with the flavor releasing particles 20 to mix the flavor medium, and the smoking taste of the aerosol is further improved.

As shown in fig. 4 to 6, the first end 101 of the capsule 10 is further opened with a third through hole area 112 formed by a plurality of through holes. The through holes in the third through hole region 112 may be referred to as third through holes 1121. It is understood that the pore size of the third through holes 1121 is smaller than the diameter of the fragrance-releasing particles 20.

As shown in fig. 2 to 5, the central axis of the first through hole region 111 and the central axis of the third through hole region 112 both coincide with the axial direction of the pipe body 30, and the first through hole region 111 may be disposed close to the central axis L of the pipe body 30 with respect to the third through hole region 112. Accordingly, the third via region 112 may be disposed around the first via region 111. In some embodiments, the first through-hole region 111 may be substantially circular, and the third through-hole region 112 may be circular.

In other embodiments, the first through-hole region 111 may be configured as a square, a cross, a pentagram, and the like. The shape of the third via region 112 may be adapted according to the shape of the first via region 111.

Referring to fig. 6, in some embodiments, the aperture of the first through hole 1111 may be larger than the aperture of the third through hole 1121. As aerosol is output through the first end 101 of the capsule 10, the wind resistance at the location of the first through-hole region 111 may be less than the wind resistance at the location of the third through-hole region 112. Accordingly, aerosol may be output from the first through-hole region 111 in a concentrated manner, and a relatively small portion of aerosol may be output through the third through-hole region 112.

As shown in fig. 4, 7 and 8, the second end 102 of the capsule 10 is further opened with a fourth through hole area 122 formed by a plurality of through holes. The through-holes of the fourth through-hole region 122 may be referred to as fourth through-holes 1221. It is understood that the diameter of the fourth through-hole 1221 may be smaller than the diameter of the fragrance-releasing particles 20.

As shown in fig. 2, 3, 7, and 8, the central axis of the fourth through hole region 122 and the central axis of the second through hole region 121 both coincide with the axial direction of the pipe body 30, and the fourth through hole region 122 may be disposed close to the central axis L of the pipe body 30 with respect to the second through hole region 121. Accordingly, the second through hole region 121 may be disposed around the periphery of the fourth through hole region 122. In some embodiments, the fourth through hole region 122 may be substantially circular, and the second through hole region 121 may be circular.

In other embodiments, the fourth aperture region 122 may be configured as a square, cross, pentagram, or the like. The shape of the second through hole region 121 is adaptable according to the shape of the fourth through hole region 122.

In some embodiments, the aperture of the fourth through-hole 1221 is smaller than the aperture of the second through-hole 1211. As the aerosol enters the cavity 103 through the second end 102 of the capsule 10, the wind resistance at the location of the second through-hole region 121 may be less than the wind resistance at the location of the fourth through-hole region 122. Accordingly, aerosol may be concentrated at the second through-hole area 121 to enter the cavity 103, and a relatively small portion of aerosol may be input into the cavity 103 through the fourth through-hole area 122.

Referring to fig. 9, in some embodiments, a projection of the first through hole region 111 perpendicular to the axial direction of the pipe body 30 may completely coincide with a projection of the fourth through hole region 122 perpendicular to the axial direction of the pipe body 30. Accordingly, a projection of the first through hole region 111 perpendicular to the axial direction of the pipe body 30 may not coincide with a projection of the second through hole region 121 perpendicular to the axial direction of the pipe body 30.

In other embodiments, a projected area of the first through hole region 111 perpendicular to the axial direction of the pipe body 30 may be larger than a projected area of the fourth through hole region 122 perpendicular to the axial direction of the pipe body 30. Accordingly, a projection of the first through hole region 111 perpendicular to the axial direction of the pipe body 30 may coincide with a projection of the second through hole region 121 perpendicular to the axial direction of the pipe body 30.

In other embodiments, as shown in fig. 10, the first via region 111 may be disposed around the periphery of the third via region 112. The fourth through hole region 122 may be disposed around the second through hole region 121. Accordingly, on a plane perpendicular to the axial direction of the pipe body 30, the projection of the first through hole region 111 may be circumferentially disposed on the projection of the second through hole region 121.

As shown in fig. 6 and 8, in some embodiments, the aperture of the first through hole 1111 may be equal to the aperture of the second through hole 1211. The aperture of the third through hole 1121 may be equal to the aperture of the fourth through hole 1221.

As shown in fig. 2 and 3, during use of the aerosol-generating article 100, when a user draws on, the aerosol may preferentially enter the capsule 10 from the second through-hole region 121 and preferentially exit from the first through-hole region 111. And a smaller portion of the aerosol enters the fourth vent region 122 and exits the third vent region 112. Inside the capsule 10, the aerosol concentrates on the path between the second through-hole area 121 to the first through-hole area 111. Thus, a difference in air pressure may be created in various areas within the capsule 10. Under the action of the air pressure difference, the tumbling of the fragrance releasing particles 20 can be enhanced, so that the flavor medium is more fully mixed in the aerosol, and the smoking taste is further improved.

In other embodiments, the diameter of the first through hole 1111 may be smaller than the diameter of the second through hole 1211. During use of the aerosol-generating article 100, the aerosol input rate may be greater than the output rate within the capsule 10, thereby further extending the residence time of the aerosol within the capsule 10, further providing for adequate mixing of the flavor medium within the aerosol, and improving the mouth feel of smoking.

Further, as shown in fig. 1 and 2, the tube 30 may have a circular tubular structure. Accordingly, the interior of the tube body 30 is hollow and forms a passage therethrough in the axial direction. In some embodiments, the capsule 10 may be received in the passage of the tube 30, and the central axis of the capsule 10 and the central axis of the passage may coincide.

In the embodiment shown in fig. 2 and 4, the side wall of the capsule 10 can be closely attached to the inner wall of the tube 30. In some embodiments, the sidewall of the capsule 10 near the connection between the first housing 11 and the second housing 12 can be closely attached to the inner wall of the tube 30.

It will be appreciated that the capsule 10 may separate the passages of the tube 30. When aerosol enters the tube 30, it can only be transported from one end of the tube 30 to the other by the capsule 10, preventing the aerosol from passing through the gap between the capsule 10 and the tube 30. As a result, the flavor medium can be mixed into the aerosol passing through the aerosol-generating article 100, so that the quality of the output aerosol can be ensured and the taste of the user can be improved. Meanwhile, the relative fixation between the capsule 10 and the tube 30 can be realized, and the effect that the flavor medium is mixed in the aerosol is prevented from being influenced by the random shaking of the capsule 10 in the tube 30.

As shown in fig. 1-3, the aerosol-generating article 100 further comprises a filter portion 40. The filter part 40 may be disposed in the passage of the tube body 30, and the filter part 40 is located downstream of the passage of the tube body 30. Thus, the filter portion 40 may filter the passing aerosol to reduce impurities in the aerosol. It will be appreciated that the flavor medium incorporated into the aerosol can pass through the filter portion 40 smoothly. In some embodiments, the filter portion 40 may be made of cellulose diacetate. In some embodiments, the first end 101 of the capsule 10 may abut the filter portion 40.

As shown in fig. 1-3, the aerosol-generating article 100 may further comprise an aerosol-generating substrate portion 50. During use of the aerosol-generating article 100, the aerosol-generating substrate portion 50 is used to generate an aerosol. The aerosol-generating substrate portion 50 may be disposed in the passage of the tube 30 with the aerosol-generating substrate portion 50 being upstream of the passage of the tube 30.

In other embodiments, the filter portion 40 and the aerosol-generating substrate portion 50 may be disposed outside the tube 30 and at two ends of the tube 30. The filter unit 40 may be in contact with one end of the tube 30, and the aerosol-generating substrate unit 50 may be in contact with the other end of the tube 30. Additionally, an outer wrapper may be provided to enclose the filter portion 40, aerosol-generating substrate portion 50 and tube body 30. The outer wrapper may be formed from a paper material such as tipping paper, wood grain paper, or from any suitable material or combination of materials. In some cases, the outer wrapper may also be formed from materials such as metal foil, metal foil composite paper, greaseproof paper, ceramics, carbon allotropes (such as graphite and graphene), plastics, wood, or combinations thereof.

In some embodiments, the second end 102 of the capsule 10 may abut the aerosol-generating substrate portion 50.

Accordingly, the two ends of the capsule 10 are respectively abutted and limited by the filtering part 40 and the aerosol-generating substrate part 50, so that the capsule 10 can be further fixed, and the capsule 10 is further prevented from moving in the pipe body 30.

In other embodiments, as shown in FIG. 11, both ends of the capsule 10 may also be in contact with neither the filter portion 40 nor the aerosol-generating substrate portion 50.

While embodiments of the present application have been shown and described above, it will be understood that the above embodiments are exemplary and should not be construed as limiting the present application and that changes, modifications, substitutions and alterations in the above embodiments may be made by those of ordinary skill in the art within the scope of the present application.
