[0028] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings of the embodiments. Clearly, the embodiments described are only some, and not all, embodiments of the present application. All other embodiments that can be obtained by a person skilled in the art without creative effort based on the embodiments of the present application are within the scope of the protection of the present application.

[0029] The terms “Examples” or “Embodiments” as used herein mean that certain features, structures, or characteristics described in conjunction with the Examples or Embodiments may be included in at least one embodiment of the Application. Nowhere in the Specification does such term necessarily refer to the same embodiment, nor does it refer to an independent or candidate embodiment that is mutually exclusive with the other embodiments. Those skilled in the art will understand, expressly or implicitly, that the embodiments described herein can be combined with other embodiments.

[0030] Furthermore, the terms "first," "second," etc., used in the specification, claims, and drawings of this application are intended to distinguish different subjects and not to describe a specific order. Also, the terms "includes," "has," and any variations thereof are intended to cover, without excluding, other components.

[0031] One embodiment This application provides a cooling assembly 10. In embodiments of this application, the cooling assembly 10 can be applied to a heated non-combustible cartridge 1. When the fumigating material 30 in the heated non-combustible cartridge 1 is heated, it generates a high-temperature aerosol, and the cooling assembly 10 is used to cool the aerosol. For example, the temperature of the aerosol generated when the fumigating material 30 is heated is typically a first temperature (e.g., 200°C to 380°C). When the aerosol having the first temperature passes through the cooling assembly 10, the temperature of the aerosol changes to a second temperature. The second temperature is lower than the first temperature. The aerosol having the second temperature is more suitable for inhalation by the user. The application of the cooling assembly 10 to the heated non-combustible cartridge 1 is an introduction to one application scenario of the cooling assembly 10 and should not be understood as an limitation of the cooling assembly 10 provided by embodiments of this application. Next, the configuration of the cooling assembly 10 will be described in detail. Referring together to Figures 1, 2, and 3, Figure 1 is a schematic perspective view of a cooling assembly provided by one embodiment of the present application, Figure 2 is an exploded perspective view of the cooling assembly in Figure 1, and Figure 3 is a cross-sectional view of the cooling assembly shown in Figure 1 along the line I-I. The cooling assembly 10 comprises a coolant 110, a first sealing member 120, and a second sealing member 130. The coolant 110 has a first end 111 and a second end 112 facing each other, and a cooling passage 110a passing through the first end 111 and the second end 112. The first sealing member 120 is fixed to the first end 111 and has at least one first through hole 121, the first through hole 121 communicating with the cooling passage 110a. The second sealing material 130 is fixed to the second end 112 and has at least one second through hole 131 which communicates with the cooling passage 110a.

[0032] The outer shape of the coolant 110 is cylindrical or substantially cylindrical, and of course, the outer shape of the coolant 110 may be rectangular, elliptical, substantially elliptical, or polygonal, and is not limited to the embodiments of this application. The cooling passage 110a is used to allow the aerosol to pass through. When the aerosol flows through the cooling passage 110a, the temperature of the aerosol gradually decreases.

[0033] In one embodiment, the material of the coolant 110 is food-grade. When an aerosol flows through the cooling passage 110a of the coolant 110, the coolant 110 receives heat and generates less or no toxic substances. For example, the material of the coolant 110 may be white cardboard or kraft paper, but is not limited to these.

[0034] If the material of the coolant 110 is white cardboard, the white cardboard is 50-200 g / m². 2 It is made of white cardboard, which gives the coolant 110 good cooling performance and strength, and makes it resistant to deformation. When the material of the coolant 110 is kraft paper, the coolant 110 is 50-200 g / m². 2 It is made of kraft paper, which gives the coolant 110 good cooling performance and strength, and makes it resistant to deformation.

[0035] To make it clear, in one embodiment, the material of the coolant 110 may be polylactic acid (PLA), silica gel, or an injection-molded product, as long as it is coolable by the coolant 110.

[0036] The method by which the first sealing material 120 is fixed to the first end 111 may be by bonding with an adhesive or by fixing with tape, but is not limited to these. In this embodiment, the first sealing material 120 is fixed to the first end 111 by an adhesive. In one embodiment, the adhesive is food-grade adhesive, and when the aerosol passes through the coolant 110, the adhesive is heated and produces less or no toxic substances. The food-grade adhesive may be glutinous rice adhesive, lap glue, straw adhesive, white emulsion adhesive, etc., but is not limited to these.

[0037] In this embodiment, the first sealing material 120 is illustrated as being fixed to the end face of the first end 111 away from the second end 112. To make it clear, in other embodiments, the first sealing material 120 may be fixed to the circumferential surface of the first end 111. Alternatively, in another embodiment, the first sealing material 120 is fixed to the end face of the first end 111 away from the second end 112 and to the circumferential surface of the first end 111.

[0038] In one embodiment, the material of the first sealing material 120 may be, but is not limited to, cotton paper, breathable paper, or butter paper. Cotton paper, breathable paper, and butter paper all have good breathability and are advantageous for the passage of aerosols. When the material of the first sealing material 120 is cotton paper, the material of the first sealing material 120 may be 1 to 50 g / m². 2 It is a type of silk floss paper. If the material of the first sealing material 120 is breathable paper, the material of the first sealing material 120 is 1 to 50 g / m². 2 It is a breathable paper. If the material of the first sealing material 120 is butter paper, the material of the first sealing material 120 is 45-105 g / m². 2 It is butter paper.

[0039] Furthermore, in order to reduce inhalation resistance when inhaling aerosols, the first sealing material 120 has at least one first through-hole 121, and the first through-hole 121 is in communication with the cooling passage 110a.

[0040] The method by which the second sealing material 130 is fixed to the second end 112 may be, but is not limited to, adhesive bonding or tape fastening. In this embodiment, the second sealing material 130 is fixed to the second end 112 by adhesive. In one embodiment, the adhesive is food-grade adhesive, and as the aerosol passes through the coolant 110, the adhesive is heated and produces less or no toxic substances. The food-grade adhesive may be, but is not limited to, glutinous rice adhesive, plastic wrap adhesive, straw adhesive, white emulsion adhesive, etc. To be understood, the method by which the second sealing material 130 is fixed to the second end 112 may be the same as, or different from, the method by which the first sealing material 120 is fixed to the first end 111, and is not limited to, the embodiments of this application.

[0041] In this embodiment, the second sealing material 130 is illustrated as being fixed to the end face of the second end 112 away from the first end 111. To make it clear, in other embodiments, the second sealing material 130 may be fixed to the circumferential surface of the second end 112. Alternatively, in another embodiment, the second sealing material 130 is fixed to the end face of the second end 112 away from the first end 111 and to the circumferential surface of the second end 112.

[0042] In one embodiment, the material of the second sealing material 130 may be, but is not limited to, cotton paper, breathable paper, or butter paper. Cotton paper, breathable paper, and butter paper all have good breathability and are advantageous for the passage of aerosols. When the material of the second sealing material 130 is cotton paper, the material of the second sealing material 130 may be 1 to 50 g / m². 2 It is a type of silk floss paper. If the material of the second sealing material 130 is breathable paper, the material of the second sealing material 130 is 1 to 50 g / m². 2 It is a breathable paper. If the material of the second sealing material 130 is butter paper, the material of the second sealing material 130 is 45-105 g / m². 2 It is butter paper. The material of the second sealing material 130 may be the same as or different from the material of the first sealing material 120, and is not limited to the embodiments of the present application.

[0043] Furthermore, in order to reduce inhalation resistance when inhaling aerosols, the second sealing material 130 has at least one second through-hole 131, and the second through-hole 131 is in communication with the cooling passage 110a.

[0044] To summarize the above, in the cooling assembly 10 provided by the embodiment of the present invention, a first sealing material 120 is fixed to the first end 111 of the coolant 110, and a second sealing material 130 is fixed to the second end 112. Therefore, when assembling the cooling assembly 10 to form a heated non-combustion cartridge 1, there is no need to distinguish between the first end 111 and the second end 112 of the cooling assembly 10. This reduces the complexity of assembling the cooling assembly 10 and improves assembly efficiency.

[0045] Furthermore, since the first sealing material 120 is fixed to the first end 111 and the second sealing material 130 is fixed to the second end 112, the coolant 110 has a good support effect at both the first end 111 and the second end 112, and deformation of the coolant 110 can be prevented. In addition, when assembling the cooling assembly 10 to form the heated non-combustion cartridge 1, the possibility of the filter 40 entering the coolant 110 can be reduced or even prevented.

[0046] Referring to Figures 4 and 5, Figure 4 is a schematic diagram of the configuration of the first sealing material in Figure 1, and Figures 5(a) to (d) are schematic diagrams of the configuration of the first sealing material in different embodiments. The number of first through holes 121 is 6 to 13, the diameter of the first through holes 121 is 0.6 mm to 1.0 mm, and the distance between any two adjacent first through holes 121 is 0.8 to 1.0 mm.

[0047] The first sealing material 120 can be formed using mold stamping, cutting tool punching, or laser cutting. The first through hole 121 can be formed using mold stamping, cutting tool punching, or laser cutting. The manufacturing process for the first sealing material 120 may be the same as or different from the manufacturing process for the first through hole 121.

[0048] The shape of the first through-hole 121 may be circular, elliptical, polygonal, trapezoidal, or roughly trapezoidal, and is not limited thereto.

[0049] If the shape of the first through-hole 121 is circular, the diameter of the first through-hole 121 is the circular diameter. If the first through-hole 121 is not circular, the diameter of the first through-hole 121 refers to the distance between the two largest points in the first through-hole 121. If the first through-hole 121 is not circular, the distance between the two largest points in the first through-hole 121 is the equivalent diameter of the first through-hole 121.

[0050] The structural design of the first through-hole 121 of the first sealing material 120 provided in the embodiment of the present application facilitates relatively uniform passage of aerosols and reduces aerosol inhalation resistance, while also maintaining the structural strength of the first sealing material 120 and making it less likely to rupture.

[0051] Referring to Figures 6 and 7, Figure 6 is a schematic diagram of the structure of the second sealing material in Figure 1, and Figures 7(a) to (d) are schematic diagrams of the configuration of the second sealing material in different embodiments. The number of second through holes 131 is 6 to 13, the diameter of the second through holes 131 is 0.6 mm to 1.0 mm, and the distance between any two adjacent second through holes 131 is 0.8 to 1.0 mm.

[0052] The second sealing material 130 can be formed using mold stamping, cutting tool punching, or laser cutting. The second through hole 131 can be formed using mold stamping, cutting tool punching, or laser cutting. The manufacturing process for the second sealing material 130 may be the same as or different from the manufacturing process for the second through hole 131.

[0053] The shape of the second through-hole 131 may be circular, elliptical, polygonal, trapezoidal, or roughly trapezoidal, and is not limited thereto.

[0054] If the shape of the second through-hole 131 is circular, the diameter of the second through-hole 131 is the diameter of the circle. If the second through-hole 131 is not circular, the diameter of the second through-hole 131 refers to the distance between the two points with the largest size in the second through-hole 131. If the second through-hole 131 is not circular, the distance between the two points with the largest size in the second through-hole 131 becomes the equivalent diameter of the second through-hole 131.

[0055] The structural design of the second through-hole 131 in the second sealing material 130 provided in the embodiment of the present application facilitates relatively uniform passage of aerosols and reduces aerosol inhalation resistance, while also maintaining the structural strength of the second sealing material 130 and making it less likely to rupture.

[0056] To make it clear, in one embodiment, the second through-hole 131 is directly opposite the first through-hole 121. In other embodiments, the second through-hole 131 is partially or completely offset from the first through-hole 121, and is not limited to this embodiment.

[0057] To make it clear, the number of second through holes 131 may be the same as or different from the number of first through holes 121. The shape of the second through holes 131 may be the same as or different from the shape of the first through holes 121. The arrangement rule for the second through holes 131 may be the same as or different from the arrangement rule for the first through holes 121. The diameter of the second through holes 131 may be the same as or different from the diameter of the first through holes 121.

[0058] Referring to Figure 8, Figure 8 schematically shows the distance between the outermost first through-hole of the first sealing material in Figure 1 and the outer edge of the first sealing material. The distance between the outermost first through-hole 121 and the outer edge of the first sealing material 120 is 0.7 mm to 0.8 mm. In Figure 8, d1 represents the distance between the outermost first through-hole 121 of the first sealing material 120 and the outer edge of the first sealing material 120, i.e., d1 satisfies 0.7 mm ≤ d1 ≤ 0.8 mm. In Figure 8, L1 is the tangent to the first through-hole 121 at point A, and L2 is the tangent to the first sealing material 120 at point B. The straight line passing through points A and B passes through the center of the first sealing material 120.

[0059] When fixing the first sealing material 120 to the coolant 110, it is necessary to leave a certain adhesive width, for example, 0.3 mm to 0.4 mm. Also, when machining the first through hole 121, machining tolerances may exist. To prevent the first through hole 121 from being machined to the edge of the first sealing material 120, or from being machined to the adhesive application area of ​​the first sealing material 120, a distance of about 0.4 mm is left. By setting the distance between the first through hole 121 located on the outermost periphery and the outer edge of the first sealing material 120 to 0.7 mm to 0.8 mm, the need to bond the first sealing material 120 to the coolant 110 can be met, on the one hand, and the need for machining tolerances when machining the first through hole 121 can be met, on the other hand.

[0060] Referring to Figure 9, Figure 9 schematically shows the distance between the outermost second through-hole of the second sealing material in Figure 1 and the outer edge of the second sealing material. The distance between the outermost second through-hole 131 and the outer edge of the second sealing material 130 is 0.7 mm to 0.8 mm. In Figure 9, d2 represents the distance between the outermost second through-hole 131 of the second sealing material 130 and the outer edge of the second sealing material 130, i.e., d2 satisfies 0.7 mm ≤ d2 ≤ 0.8 mm. In Figure 9, L3 is the tangent to the second through-hole 131 at point C, and L4 is the tangent to the second sealing material 130 at point D. The straight line passing through points C and D passes through the center of the second sealing material 130.

[0061] When fixing the second sealing material 130 to the coolant 110, it is necessary to leave a certain adhesive width, for example, 0.3 mm to 0.4 mm. Also, when machining the second through hole 131, there may be machining tolerances. To prevent the second through hole 131 from being machined to the edge of the second sealing material 130, or from being machined to the adhesive application area of ​​the second sealing material 130, a distance of about 0.4 mm is left. By setting the distance between the second through hole 131 located on the outermost periphery and the outer edge of the second sealing material 130 to 0.7 mm to 0.8 mm, the need to bond the second sealing material 130 to the coolant 110 can be met, on the one hand, and the need for machining tolerances when machining the second through hole 131 can be met, on the other hand.

[0062] Referring to Figure 10, which is a schematic diagram of the structure of a coolant provided by one embodiment, the coolant 110 includes a plurality of flat-wound cooling layers 1111. When the coolant 110 includes a plurality of flat-wound cooling layers 1111, the number of cooling layers 1111 may be 3 to 6, for example, 3, 4, 5, or 6 layers. By including a plurality of flat-wound cooling layers 1111 in the coolant 110, the coolant 110 has good strength and is resistant to deformation.

[0063] In addition, flat winding refers to a condition where the direction of the seam L01 of the cooling layer 1111 and the direction of the center line L02 of the coolant 110 are parallel or approximately parallel.

[0064] Figure 11 is a schematic diagram of the structure of a coolant provided by another embodiment. In this embodiment, the coolant 110 includes a plurality of spirally wound cooling layers 1111.

[0065] In this embodiment, the coolant 110 includes a plurality of spirally wound cooling layers 1111. When the coolant 110 includes a plurality of spirally wound cooling layers 1111, the number of cooling layers 1111 may be 2 to 4, for example, 2 layers, 3 layers, or 4 layers. By including a plurality of spirally wound cooling layers 1111, the coolant 110 has good strength and is less prone to deformation.

[0066] Spiral winding refers to a condition where the extension line L01 of the seam between adjacent cooling layers 1111 is inclined with respect to the direction of the center line L02 of the coolant 110, exhibiting an inclination angle of, for example, 135°±15°. An inclination angle of 135°±15° can also be considered as 45°±15°. In other words, the angle between the extension lines L01 and L02 of the seam is 45°±15°.

[0067] Compared to a coolant 110 containing multiple flat-wound cooling layers 1111, a coolant 110 containing multiple spiral-wound cooling layers 1111 has adhesive between each cooling layer 1111, so the spaces between each layer of cooling layers 1111 can be firmly fixed, and consequently the coolant 110 has better stability, better strength, and better roundness (the openings of the coolant 110 are rounder).

[0068] Referring to Figure 12, which is a schematic diagram showing the outer and inner diameters of the coolant in Figure 1. The coolant 110 is tubular, with an outer diameter of 6.0 mm to 6.6 mm (labeled D1 in Figure 12) and an inner diameter of 6.2 mm to 6.4 mm (labeled D2 in Figure 12).

[0069] The inner diameter of the coolant 110 is smaller than the outer diameter of the coolant 110. Because the difference between the range of the inner diameter and the range of the outer diameter of the coolant 110 is small, for a coolant 110 with an outer diameter of a certain size, the coolant 110 has a large inner diameter, that is, a cooling passage 110a of a large size in the radial direction, and as a result the coolant 110 has a good cooling effect on aerosols. In addition, since a large amount of aerosol can be stored in the cooling passage 110a, when inhaling the heated non-combustion cartridge 1 to which the cooling assembly 10 is applied, it is also possible to inhale aerosols of a relatively uniform amount.

[0070] The diameter of the first sealing material 120 is suitable for the outer diameter of the coolant 110, for example, the diameter of the first sealing material 120 is 6.0 mm to 6.6 mm.

[0071] The diameter of the second sealing material 130 is matched to the outer diameter of the coolant 110, for example, the diameter of the second sealing material 130 is 6.0 mm to 6.6 mm.

[0072] Referring together to Figures 13, 14, 15, and 16, Figure 13 is a schematic perspective view of the structure of a heated non-combustible cartridge provided by one embodiment of the present application, Figure 14 is an exploded perspective view of the heated non-combustible cartridge in Figure 13, Figure 15 is a cross-sectional view of the heated non-combustible cartridge in Figure 13 along line II-II, and Figure 16 is an enlarged schematic view of Part III in Figure 15. The heated non-combustible cartridge 1 comprises a first tube 20, a smoke-generating material 30, a cooling assembly 10, and a filter 40. The first tube 20 has a housing space 210. The smoke-generating material 30 is provided within the housing space 210 and is located at one end of the first tube 20. The coolant 110 is provided within the housing space 210, and the cooling assembly 10 is provided on one side of the smoke-generating material 30. The specific configuration of the coolant 110 is described above and will not be repeated here. The filter 40 is located within the containment space 210 and is positioned on the side of the coolant 110 that is away from the smoke-generating material 30.

[0073] The shape of the first tube 20 is circular or substantially circular, and of course, the shape of the first tube 20 may be rectangular, elliptical, substantially elliptical, polygonal, etc., and is not limited to the embodiments of this application.

[0074] In one embodiment, one end of the first tube 20 is sealed to prevent the smoke-generating material 30 from leaking out of the first tube 20. Specifically, in one embodiment, the heated non-combustible cartridge 1 further comprises a sealant 60. The sealant 60 is provided at one end of the first tube 20 and seals the first tube 20. The sealant 60 is provided on the side of the smoke-generating material 30 away from the cooling assembly 10. The sealant 60 may be, but is not limited to, cotton paper, breathable paper, or butter paper. For example, 1 to 50 g / m² 2 Silk floss paper, or 1-50g / m² 2 Breathable paper, or 45-105 g / m² 2 Butter paper is also acceptable.

[0075] The smoke generating material 30 is also called a smoke generating segment. The smoke generating material 30 contains an aerosol generating substrate (for example, at least one of smoke particles or smoke generating sheets). The material of the aerosol generating substrate includes tobacco or non-tobacco plant herbaceous units. If the aerosol generating substrate contains non-tobacco plant herbaceous units, the aerosol generating substrate does not produce harmful substances such as tar and nicotine, and the heated plant herbaceous units do not burn, thus not polluting the surrounding environment or affecting people in the vicinity, thereby ensuring the health of the person inhaling the heated non-combustible cartridge 1 and those in the surrounding area. In addition, if the plant herbaceous units in the aerosol generating substrate contain materials of herbal medicine components (for example, ginseng, gastrodia elata), inhaling the heated non-combustible cartridge 1 can have better health benefits.

[0076] When the smoke generating material 30 contains smoke particles or smoke sheets, the smoke generating material 30 is less likely to remain on the smoking device when the heated non-combustion cartridge 1 is heated by the smoking device, thus ensuring the cleanliness of the smoking device. Furthermore, when the smoke generating material 30 contains smoke particles or smoke sheets, gaps are likely to exist between the smoke particles or between the smoke sheets, providing sufficient air, which allows for the generation of an aerosol when the smoke generating material 30 is heated by the smoking device.

[0077] In this embodiment, the first sealing material 120 of the cooling assembly 10 is provided adjacent to the smoke generating material 30. In another embodiment, the second sealing material 130 of the cooling assembly 10 is provided adjacent to the smoke generating material 30.

[0078] The filter 40 is provided within the housing space 210 and on the side of the coolant 110 away from the smoke-generating material 30. The filter 40 may be in contact with the cooling assembly 10, or it may be spaced apart from the cooling assembly 10, and is not limited in this application.

[0079] The material of the filter 40 may be, but is not limited to, polylactic acid fiber. The filter 40 can filter aerosols and improve the mouthfeel when inhaling the heated non-combustible cartridge 1. In one embodiment, the filter 40 is provided so as to be compressed within the first tube 20, thereby preventing the filter 40 from falling out of the first tube 20.

[0080] The smoke-generating material 30 generates a high-temperature aerosol when heated. Specifically, when heated, the smoke-generating material 30 can generate an aerosol at a first temperature (e.g., 200°C to 380°C). By inhaling the heated non-combustion cartridge 1 through the filter 40, the aerosol at the first temperature passes sequentially through the cooling assembly 10 and the filter 40. After passing through the cooling assembly 10, the aerosol at the first temperature decreases to a second temperature, which is lower than the first temperature. The aerosol at the second temperature is suitable for inhalation by the user, preventing burns to the user.

[0081] Referring again to Figure 15, the length of the smoke generating material 30 is 13mm to 18mm, the length of the cooling assembly 10 is 16mm to 23mm, and the length of the filter 40 is 8mm to 10mm.

[0082] The above-described sizes of the smoke-generating material 30, cooling assembly 10, and filter 40 in the heated non-combustion cartridge 1 provided by the embodiment of the present application allow the smoke-generating material 30 to generate a large amount of aerosol, the cooling assembly 10 to have a good cooling effect on the aerosol generated by the smoke-generating material 30, and the filter 40 to have a good filtering effect on the aerosol, thereby enabling the heated non-combustion cartridge 1 to provide a good smoking experience.

[0083] Referring together to Figures 17, 18, 19, and 20, Figure 17 is a schematic perspective view of the structure of a heated non-combustible cartridge provided in another embodiment of the present application; Figure 18 is an exploded perspective view of the heated non-combustible cartridge in Figure 17; Figure 19 is a cross-sectional view of the heated non-combustible cartridge in Figure 17 along line IV-IV; and Figure 20 is an enlarged schematic view of part V in Figure 19. In this embodiment, the heated non-combustible cartridge 1 further comprises a second tube 150, which is provided on the circumferential surface of the first tube 20.

[0084] Specifically, when manufacturing the heated non-combustion cartridge 1, defects may occur in the appearance of the first tube 20 for various reasons. For example, the first tube 20 may be soiled by the smoke-generating material 30, or the first tube 20 may have scratches.

[0085] The second tube 150 is provided on the circumferential surface of the first tube 20, thereby shielding the first tube 20 and making the heated non-combustion cartridge 1 more aesthetically pleasing. In one embodiment, the material of the second tube 150 is chip paper. In one embodiment, this chip paper is 32-40 g / m². 2This is a chip paper. In one embodiment, the heated non-combustion cartridge 1 is provided under the following conditions, namely: The material of the first tube 20 is 50-200 g / m 2 White cardboard, or 50-200 g / m² 2 It is kraft paper, The length of the first tube 20 is 42mm to 46mm, and if the heated non-combustion cartridge 1 further comprises a second tube 150, the length of the second tube 150 is 42mm to 46mm. The outer diameter of the coolant 110 is 6.0 mm to 6.6 mm, the inner diameter of the first tube 20 is 6.4 mm to 6.65 mm, the outer diameter of the first tube 20 is 6.9 mm to 7.1 mm, the outer diameter of the filter 40 is 6.5 mm to 7.0 mm, and the filter 40 is installed so as to be compressed inside the first tube 20. If the heated non-combustion cartridge 1 further comprises a second tube 150, the outer diameter of the coolant 110 is 6.0 mm to 6.6 mm, the inner diameter of the first tube 20 is 6.4 mm to 6.65 mm, the outer diameter of the first tube 20 is 6.9 mm to 7.1 mm, the outer diameter of the filter 40 is 6.5 mm to 7.0 mm, the filter 40 is provided so as to be compressed inside the first tube 20, and the outer diameter of the second tube 150 is 7.15 mm to 7.3 mm. It satisfies at least one of the following conditions.

[0086] Another Embodiment The present application provides a heated non-combustible cartridge 1. Referring together to Figures 21 to 25, Figure 21 is a schematic perspective view of a heated non-combustible cartridge provided by one embodiment of the present application, Figure 22 is an exploded perspective view of the heated non-combustible cartridge shown in Figure 21, Figure 23 is a cross-sectional view of the heated non-combustible cartridge shown in Figure 21 along the line VI-VI, Figure 24 is a schematic perspective view of the cooling assembly shown in Figure 22, and Figure 25 is an exploded perspective view of the cooling assembly in Figure 24. The heated non-combustible cartridge 1 comprises a first tube 20, a smoke generating material 30, a cooling assembly 10, and a filter 40. The first tube 20 has a housing space 210 and the first tube 20 has a sealed first end 20a and an open second end 20b. The smoke generating material 30 is provided in the housing space 210 and is located at the first end 20a of the first tube 20. At least one of the cooling assembly 10 and the smoke-generating material 30 is movably provided within the containment space 210, and the cooling assembly 10 is provided on one side of the smoke-generating material 30 away from the first end 20a. The cooling assembly 10 comprises a coolant 110 and a sealing material 140. The coolant 110 has a cooling passage 110a. The sealing material 140 is fixed to one end of the coolant 110 and is provided closer to the smoke-generating material 30 than the coolant 110, and the sealing material 140 has a plurality of through holes 141 communicating with the cooling passage 110a. The filter 40 is provided within the containment space 210 and is provided at one end of the coolant 110 away from the sealing material 140.

[0087] The first tube 20 includes a first end 20a and a second end 20b. In this embodiment, the first end 20a is positioned opposite the second end 20b. The first end 20a is sealed to prevent the smoke-generating material 30 from leaking out of the first end 20a, while the second end 20b is open. When the heated non-combustible cartridge 1 is being sucked by the user, the first end 20a is the end furthest from the lips and is also called the far lip end, and the second end 20b is the end closest to the lips and is also called the near lip end.

[0088] In this embodiment, the first end 20a can be sealed with a sealing material 60. The sealing material 60 is provided at the first end 20a of the first pipe 20 to seal the first pipe 20. The sealing material 60 is provided on the side of the smoke generating material 30 away from the cooling assembly 10. The sealing material 60 may be, but is not limited to, cotton paper, breathable paper, or butter paper. For example, 1 to 50 g / m² 2 Silk floss paper, or 1-50g / m² 2 Breathable paper, or 45-105 g / m² 2 Butter paper is also acceptable.

[0089] The shape of the first tube 20 is circular or substantially circular, and of course, the shape of the first tube 20 may be rectangular, elliptical, substantially elliptical, polygonal, etc., and is not limited to the embodiments of this application.

[0090] The smoke generating material 30 is also called a smoke generating segment. The smoke generating material 30 contains an aerosol generating substrate (for example, at least one of smoke particles or smoke generating sheets). The material of the aerosol generating substrate includes tobacco or non-tobacco plant herbaceous units. If the aerosol generating substrate contains non-tobacco plant herbaceous units, the aerosol generating substrate does not produce harmful substances such as tar and nicotine, and the heated plant herbaceous units do not burn, thus not polluting the surrounding environment or affecting people in the vicinity, thereby ensuring the health of the person inhaling the heated non-combustible cartridge 1 and those in the surrounding area. In addition, if the plant herbaceous units in the aerosol generating substrate contain materials of herbal medicine components (for example, ginseng, gastrodia elata), inhaling the heated non-combustible cartridge 1 can have better health benefits.

[0091] When using the heated non-combustion cartridge 1, the heating element of the smoking device is usually inserted into the smoke-generating material 30 to heat the smoke-generating material 30. When the smoke-generating material 30 is heated by the smoking device, it can generate an aerosol (commonly known as smoke), but the fact that the smoke-generating material 30 does not reach the combustion temperature and therefore does not burn is also why the cartridge is called a heated non-combustion cartridge 1.

[0092] When the smoke generating material 30 contains smoke particles or smoke sheets, the smoke generating material 30 is less likely to remain on the smoking device when the heated non-combustion cartridge 1 is heated by the smoking device, thus ensuring the cleanliness of the smoking device. Furthermore, when the smoke generating material 30 contains smoke particles or smoke sheets, gaps are likely to exist between the smoke particles or between the smoke sheets, providing sufficient air, which allows for the generation of an aerosol when the smoke generating material 30 is heated by the smoking device.

[0093] The coolant 110 is provided within the containment space 210. In the heated non-combustible cartridge 1 provided by the embodiment of the present invention, at least one of the cooling assembly 10 and the smoke-generating material 30 is movably provided within the containment space 210. When the heating needle of the smoking device is inserted into the smoke-generating material 30, at least one of the smoke-generating material 30 and the cooling assembly 10 moves, resulting in a small or no change in density in the portion of the smoke-generating material 30 inserted into the heating needle. This has little to no effect on the mouthfeel of the heated non-combustible cartridge 1 (for example, low inhalation resistance and a large amount of aerosol). In other words, the heated non-combustible cartridge 1 provided by the embodiment of the present invention has a good mouthfeel.

[0094] The fume-generating material 30 of the heated non-combustion cartridge 1 generates a high-temperature aerosol when heated. The aerosol is transmitted to the filter 40 via the cooling passage 110a of the coolant 110 and discharged from the filter 40. The cooling assembly 10 is used to cool the aerosol. For example, the temperature of the aerosol generated when the fume-generating material 30 is heated is usually a first temperature (e.g., 200°C to 380°C). When the aerosol with the first temperature passes through the cooling assembly 10, the temperature of the aerosol changes to a second temperature. The second temperature is lower than the first temperature. The aerosol with the second temperature is more suitable for inhalation by the user.

[0095] The outer shape of the coolant 110 is cylindrical or substantially cylindrical, and of course, the outer shape of the coolant 110 may be rectangular, elliptical, substantially elliptical, or polygonal, and is not limited to the embodiments of this application. The cooling passage 110a is used to allow the aerosol to pass through. When the aerosol flows through the cooling passage 110a, the temperature of the aerosol gradually decreases.

[0096] In one embodiment, the material of the coolant 110 is food-grade. When an aerosol flows through the cooling passage 110a of the coolant 110, the coolant 110 receives heat and generates less or no toxic substances. For example, the material of the coolant 110 may be white cardboard or kraft paper, but is not limited to these.

[0097] If the material of the coolant 110 is white cardboard, the white cardboard is 50-200 g / m². 2 It is made of white cardboard, which gives the coolant 110 good cooling performance and strength, and makes it resistant to deformation. When the material of the coolant 110 is kraft paper, the coolant 110 is 50-200 g / m². 2 It is made of kraft paper, which gives the coolant 110 good cooling performance and strength, and makes it resistant to deformation.

[0098] To make it clear, in one embodiment, the material of the coolant 110 may be polylactic acid (PLA), silica gel, or an injection-molded product, as long as it is coolable by the coolant 110.

[0099] Referring to Figure 26, which is a schematic diagram of the structure of a coolant provided by one embodiment, the coolant 110 includes a plurality of flat-wound cooling layers 1111. When the coolant 110 includes a plurality of flat-wound cooling layers 1111, the number of cooling layers 1111 may be 3 to 6, for example, 3, 4, 5, or 6 layers. By including a plurality of flat-wound cooling layers 1111 in the coolant 110, the coolant 110 has good strength and is resistant to deformation.

[0100] In addition, flat winding refers to a condition where the direction of the seam L01 of the cooling layer 1111 and the direction of the center line L02 of the coolant 110 are parallel or approximately parallel.

[0101] Referring to Figure 27, which is a schematic diagram of the structure of a coolant provided by another embodiment, in this embodiment the coolant 110 includes a plurality of spirally wound cooling layers 1111.

[0102] In this embodiment, the coolant 110 includes a plurality of spirally wound cooling layers 1111. When the coolant 110 includes a plurality of spirally wound cooling layers 1111, the number of cooling layers 1111 may be 2 to 4, for example, 2 layers, 3 layers, or 4 layers. By including a plurality of spirally wound cooling layers 1111, the coolant 110 has good strength and is less prone to deformation.

[0103] Spiral winding refers to a condition where the extension line L01 of the seam between adjacent cooling layers 1111 is inclined with respect to the direction of the center line L02 of the coolant 110, exhibiting an inclination angle of, for example, 135°±15°. An inclination angle of 135°±15° can also be considered as 45°±15°. In other words, the angle between the extension lines L01 and L02 of the seam is 45°±15°.

[0104] Compared to a coolant 110 containing multiple flat-wound cooling layers 1111, a coolant 110 containing multiple spiral-wound cooling layers 1111 has adhesive between each cooling layer 1111, so the spaces between each layer of cooling layers 1111 can be firmly fixed, and consequently the coolant 110 has better stability, better strength, and better roundness (the openings of the coolant 110 are rounder).

[0105] The sealing material 140 is fixed to the first end 20a by adhesive bonding or by tape, but is not limited to these methods. In this embodiment, the sealing material 140 is fixed to the first end 20a by adhesive. In one embodiment, the adhesive is food-grade adhesive, and when the aerosol passes through the coolant 110, the adhesive is heated and produces less or no toxic substances. The food-grade adhesive may be glutinous rice adhesive, plastic wrap adhesive, straw adhesive, white emulsion adhesive, etc., but is not limited to these.

[0106] In this embodiment, the sealing material 140 is shown to be fixed to the end face of the first end 20a away from the second end 20b. To make it clear, in other embodiments, the sealing material 140 may be fixed to the circumferential surface of the first end 20a. Alternatively, in another embodiment, the sealing material 140 is fixed to the end face of the first end 20a away from the second end 20b and to the circumferential surface of the first end 20a.

[0107] In one embodiment, the material of the sealing material 140 may be, but is not limited to, cotton paper, breathable paper, or butter paper. Cotton paper, breathable paper, and butter paper all have good breathability and are advantageous for the passage of aerosols. When the material of the sealing material 140 is cotton paper, the material of the sealing material 140 may be 1 to 50 g / m². 2 It is a type of silk floss paper. If the material of the sealing material 140 is breathable paper, the material of the sealing material 140 is 1-50 g / m². 2 It is a breathable paper. If the material of sealing material 140 is butter paper, the material of sealing material 140 is 45-105 g / m². 2 It is butter paper.

[0108] Furthermore, in order to reduce inhalation resistance when inhaling aerosols, the sealing material 140 has at least one through-hole 141, and the through-hole 141 is in communication with the cooling passage 110a.

[0109] The material of the filter 40 may be, but is not limited to, polylactic acid fiber. The filter 40 can filter aerosols and improve the mouthfeel when inhaling the heated non-combustible cartridge 1. In one embodiment, the filter 40 is provided so as to be compressed within the first tube 20, thereby preventing the filter 40 from falling out of the first tube 20. The provision of the filter 40 to be compressed within the first tube 20 means that the filter 40 has a first volume in its natural state and a second volume when provided within the first tube 20, with the first volume being greater than the second volume. The provision of the filter 40 in its natural state means that the filter 40 is not subjected to pressure or tension. When assembling the heated non-combustible cartridge 1, the filter 40 needs to be compressed, and the filter 40 can be provided within the first tube 20 after it has been compressed. Furthermore, when the filter 40 is removed from the first tube 20, the radial size of the filter 40 may be larger than the radial size of the inner diameter of the first tube 20.

[0110] Referring to Figures 28 and 29, Figure 28 is a schematic diagram of the structure of the sealing material in Figure 22, and Figures 29(a) to (d) are schematic diagrams of the configuration of the sealing material in different embodiments. The number of through holes 141 is 6 to 13. The diameter of the through holes 141 is 0.6 mm to 1.0 mm, and the distance between any two adjacent through holes 141 is 0.8 to 1.0 mm.

[0111] The sealing material 140 can be formed using mold stamping, cutting tool punching, or laser cutting. The through hole 141 can be formed using mold stamping, cutting tool punching, or laser cutting. The manufacturing process for the sealing material 140 may be the same as or different from the manufacturing process for the through hole 141.

[0112] The shape of the through-hole 141 may be circular, elliptical, polygonal, trapezoidal, or roughly trapezoidal, and is not limited thereto.

[0113] If the through-hole 141 is circular in shape, the diameter of the through-hole 141 is the diameter of the circle. If the through-hole 141 is not circular, the diameter of the through-hole 141 refers to the distance between the two points with the largest size in the through-hole 141. If the through-hole 141 is not circular, the distance between the two points with the largest size in the through-hole 141 is the equivalent diameter of the through-hole 141.

[0114] In the embodiments of the present invention, the above-described structural design of the through-hole 141 of the sealing material 140 facilitates relatively uniform passage of aerosols and reduces aerosol inhalation resistance, while also maintaining the structural strength of the sealing material 140 and preventing the sealing material 140 from rupturing.

[0115] Referring to Figure 30, which schematically shows the distance between the outermost through-hole of the sealing material and the outer edge of the sealing material in Figure 25. The distance between the outermost through-hole 141 and the outer edge of the sealing material 140 is 0.7 mm to 0.8 mm. In Figure 30, d1 represents the distance between the outermost through-hole 141 of the sealing material 140 and the outer edge of the sealing material 140, i.e., d1 satisfies 0.7 mm ≤ d1 ≤ 0.8 mm. In Figure 30, L1 is the tangent to the through-hole 141 at point A, and L2 is the tangent to the sealing material 140 at point B. The straight line passing through points A and B passes through the center of the sealing material 140.

[0116] When fixing the sealing material 140 to the coolant, it is necessary to leave a certain adhesive width, for example, 0.3 mm to 0.4 mm. Also, when machining the through hole 141, there may be machining tolerances. To prevent the through hole 141 from being machined to the edge of the sealing material 140, or from being machined to the adhesive application area of ​​the sealing material 140, a distance of about 0.4 mm is left. By setting the distance between the outermost through hole 141 and the outer edge of the sealing material 140 to 0.7 mm to 0.8 mm, the need to bond the sealing material 140 to the coolant can be met, on the one hand, and the need for machining tolerances when machining the through hole 141 can be met, on the other hand.

[0117] Referring also to Figure 31, which is a cross-sectional view along the line VI-VI of a heated non-combustible cartridge provided by another embodiment, and Figure 32 is an enlarged schematic view of part G in Figure 31. When the filter 40 of the heated non-combustible cartridge 1 is located below the cooling assembly 10, there is a gap G0 between the smoke-generating material 30 and the sealing material 60 at the first end 20a.

[0118] When the filter 40 of the heated non-combustion cartridge 1 is located below the cooling assembly 10, there is a gap G0 between the smoke-generating material 30 and the end face of the first end 20a. Since the sealing material 60 is located at the first end 20a, there is a gap G0 between the smoke-generating material 30 and the sealing material 60 at the first end 20a, and there is relatively sufficient space for movement when at least one of the smoke-generating material 30 and the cooling assembly 10 moves within the first tube 20. When the heating needle of the smoking device is inserted into the smoke-generating material 30, at least one of the smoke-generating material 30 and the cooling assembly 10 moves, and the density change of the portion of the smoke-generating material 30 inserted into the heating needle is small or nonexistent, so as not to affect the mouthfeel when smoking the heated non-combustion cartridge 1.

[0119] When the heated non-combustion cartridge 1 is heated by the smoking device, the smoke-generating material 30 of the heated non-combustion cartridge 1 is below the filter 40, but there is sufficient movable space within the first tube 20. Therefore, when the heating needle of the smoking device is inserted into the smoke-generating material 30, at least one of the smoke-generating material 30 and the cooling assembly 10 moves, resulting in little or no change in density of the portion of the smoke-generating material 30 inserted into the heating needle, thus not affecting the mouthfeel when smoking the heated non-combustion cartridge 1.

[0120] Referring further to Figure 32, the heated non-combustible cartridge 1 further comprises a sealant 60, which is sealed to the first end 20a of the first tube 20. When the filter 40 of the heated non-combustible cartridge 1 is located below the cooling assembly 10, the height h1 of the gap G0 between the smoke-generating material 30 and the sealant 60 is 1.5 mm ± 10%.

[0121] The height h1 of the gap G0 is 1.5 mm ± 10%, that is, the height h1 of the gap G0 is 1.35 mm to 1.65 mm. In the embodiments / examples of this application, unless otherwise specified, the numerical range A to B includes both endpoint value A and endpoint value B. The gap is 1.35 mm to 1.65 mm, and for example, the gap may be 1.35 mm, or 1.40 mm, or 1.45 mm, or 1.50 mm, or 1.55 mm, or 1.60 mm, or 1.65 mm, but is not limited to these.

[0122] When the filter 40 of the heated non-combustion cartridge 1 is located below the cooling assembly 10, if the gap between the smoke-generating material 30 and the sealing material 60 is less than 1.35 mm, the gap between the smoke-generating material 30 and the sealing material 60 is relatively small. When a heating needle is inserted into the smoke-generating material 30 of the heated non-combustion cartridge 1, the heating needle causes a large change in the density of the part of the smoke-generating material 30 where the heating needle is inserted (the density of the inserted part increases), which in turn affects the mouthfeel when inhaling the heated non-combustion cartridge 1.

[0123] If the filter 40 of the heated non-combustion cartridge 1 is located below the cooling assembly 10, and the gap between the smoke-generating material 30 and the sealing material 60 is greater than 1.65 mm, then the gap between the smoke-generating material 30 and the sealing material 60 is relatively large. When a heating needle is inserted into the smoke-generating material 30 of the heated non-combustion cartridge 1, the density change in the portion of the smoke-generating material 30 into which the heating needle is inserted is small, or even nonexistent. However, the smoke-generating material 30 may not be able to make good contact with the heating needle of the smoking device, which in turn affects the mouthfeel when smoking the heated non-combustion cartridge 1.

[0124] To make it clear, in this embodiment, when the filter 40 of the heated non-combustible cartridge 1 is located below the cooling assembly 10, the height of the gap between the smoke-generating material 30 and the sealing material 60 is 1.5 mm ± 10%. In other embodiments, when the filter 40 of the heated non-combustible cartridge 1 is located below the cooling assembly 10, there should be a gap between the smoke-generating material 30 and the sealing material 60. In this case as well, when the heating needle of the smoking device is inserted into the heated non-combustible cartridge 1, the density change in the portion of the smoke-generating material 30 into which the heating needle is inserted is reduced to a certain extent, and consequently the effect of the density change on the mouthfeel when smoking the heated non-combustible cartridge 1 is reduced, or even avoided.

[0125] Furthermore, referring to Figure 33, which is an enlarged schematic diagram of part P in Figure 31. Part of the filter 40 is housed in the cooling passage 110a.

[0126] The coolant 110 is open at one end away from the sealing material 140, and since the sealing material 140 is not provided, a portion of the filter 40 is housed in the cooling passage 110a from the end away from the sealing material 140. Because a portion of the filter 40 is housed in the cooling passage 110a from the end away from the sealing material 140, the aerosol emitted from the coolant 110 easily enters the filter 40, and large particles in the aerosol are absorbed and filtered, thereby improving the mouthfeel when inhaling the heated non-combustion cartridge 1.

[0127] Referring to Figure 33, one end of the filter 40 that is away from the cooling assembly 10 is recessed into the housing space 210. Because one end of the filter 40 that is away from the cooling assembly 10 is recessed into the housing space 210, less of the filter 40 enters the user's mouth when the user inhales the heated non-combustible cartridge 1, making it relatively hygienic when the heated non-combustible cartridge 1 is inhaled.

[0128] In another embodiment, one end of the filter 40 away from the cooling assembly 10 is flush with the end face of the second end 20b away from the first end 20a. In other words, one end of the filter 40 away from the cooling assembly 10 is flush with the end face of the first tube 20. When one end of the filter 40 away from the cooling assembly 10 is flush with the end face of the second end 20b away from the first end 20a, the heated non-combustible cartridge 1 has a good appearance. Furthermore, there is less and less of the filter 40 that enters the user's mouth when the heated non-combustible cartridge 1 is inhaled, making it relatively hygienic when the heated non-combustible cartridge 1 is inhaled.

[0129] Referring again to Figure 22 or Figure 30, the smoke generating material 30 includes at least one of a plurality of smoke generating particles or smoke generating sheets, the length of the smoke generating material 30 is 13 mm to 16.5 mm, the length of the cooling assembly 10 is 16 mm to 23 mm, and the length of the filter 40 is 8 mm to 10 mm.

[0130] The above-described sizes of the smoke-generating material 30, cooling assembly 10, and filter 40 in the heated non-combustion cartridge 1 provided by the embodiment of the present application allow the smoke-generating material 30 to generate a large amount of aerosol, the cooling assembly 10 to have a good cooling effect on the aerosol generated by the smoke-generating material 30, and the filter 40 to have a good filtering effect on the aerosol, thereby enabling the heated non-combustion cartridge 1 to provide a good smoking experience.

[0131] Referring together to Figures 34, 35, 36, and 37, Figure 34 is a schematic perspective view of the structure of a heated non-combustible cartridge provided by one embodiment of the present application, Figure 35 is an exploded perspective view of the heated non-combustible cartridge in Figure 34, Figure 36 is a cross-sectional view of the heated non-combustible cartridge in Figure 34 along line VII-VII, and Figure 37 is an enlarged schematic view of part Q in Figure 36. In this embodiment, the heated non-combustible cartridge 1 further comprises a second tubular body 50, which is provided on the circumferential surface of the first tubular body 20.

[0132] Specifically, when manufacturing the heated non-combustion cartridge 1, defects may occur in the appearance of the first tube 20 for various reasons. For example, the first tube 20 may be soiled by the smoke-generating material 30, or the first tube 20 may have scratches.

[0133] The second tube 50 is provided on the circumferential surface of the first tube 20, thereby shielding the first tube 20 and making the heated non-combustion cartridge 1 more aesthetically pleasing. In one embodiment, the material of the second tube 50 is chip paper. In one embodiment, this chip paper is 32-40 g / m². 2 This is a chip paper.

The outer diameter of the coolant 110 is 6.0 mm to 6.6 mm, the inner diameter of the first tube 20 is 6.4 mm to 6.65 mm, the outer diameter of the first tube 20 is 6.9 mm to 7.1 mm, the outer diameter of the filter 40 is 6.5 mm to 7.0 mm, and the filter 40 is installed so as to be compressed inside the first tube 20. If the heated non-combustion cartridge 1 further comprises a second tube 50, the outer diameter of the coolant 110 is 6.0 mm to 6.6 mm, the inner diameter of the first tube 20 is 6.4 mm to 6.65 mm, the outer diameter of the first tube 20 is 6.9 mm to 7.1 mm, the outer diameter of the filter 40 is 6.5 mm to 7.0 mm, the filter 40 is provided so as to be compressed within the first tube 20, and the outer diameter of the second tube 50 is 7.15 mm to 7.3 mm.

It is understood that this should not constitute a limitation of the heated non-combustible cartridge 1 provided by the embodiments of the present application. The heated non-combustible cartridge 1 further comprising a second tube 50 can be incorporated into any of the previous embodiments. When one end of the filter 40 away from the cooling assembly 10 is flush with the end face of the first tube 20, the heated non-combustible cartridge 1 has a good appearance. Furthermore, there is less and less of the filter 40 that enters the user's mouth when the user inhales the heated non-combustible cartridge 1, and the heated non-combustible cartridge 1 is relatively hygienic when inhaled.
