[0018] The embodiment of the present application provides a heating non-combustion cartridge 1. With reference to FIG. 1, FIG. 2 and FIG. 3, FIG. 1 is a schematic diagram showing the structure of a heating non-combustion cartridge according to an embodiment of the present application, FIG. 2 is an exploded perspective view of the heating non-combustion cartridge according to the embodiment of FIG. 1, and FIG. 3 is a schematic diagram of a cross section along line AA in one embodiment of the heating non-combustion cartridge according to the embodiment of FIG. 1. In this embodiment, the heating non-combustion cartridge 1 includes a tube 10, a sealing section 20, a smoke-generating section 30, a cooling section 40 and a filtering section 50. The tube 10 has a first end 11 and a second end 12 arranged back to back. The sealing section 20 is used to seal the first end 11. The smoke-generating section 30 is accommodated in the tube 10 and is provided adjacent to the first end 11. The cooling section 40 is accommodated in the tube 10 and is provided adjacent to the smoke-generating section 30. The filtering section 50 is accommodated in the tube 10 and is provided at the second end 12. The filtering section 50 and the cooling section 40 are spaced apart to define a receiving cavity 60 .

[0019] In this embodiment, the tube 10 has a housing function. Specifically, the tube 10 is used to house the smoke generating section 30, the cooling section 40 and the filtering section 50. The material of the tube 10 is an edible grade material, and has a density of 50 to 200 g / m 2 White board and 50~200g / m 2The kraft paper may be one or more of, but is not limited to, the above. In one embodiment, the tube 10 is manufactured by flat-winding an edible-grade material. Specifically, the tube 10 is manufactured by flat-winding two or three layers of edible-grade material. In another embodiment, the tube 10 is manufactured by diagonally winding an edible-grade material. Specifically, the tube 10 is manufactured by diagonally winding two or three layers of edible-grade material. Specifically, the length L0 of the tube 10 satisfies 42 mm≦L0≦46 mm, the inner diameter D0 of the tube 10 satisfies 6.4 mm≦D0≦6.65 mm, and the outer diameter D00 of the tube 10 satisfies 6.9 mm≦D00≦7.1 mm. When the heating and non-combustion cartridge 1 is used by a user, the first end 11 of the tube 10 is an end farther from the lips, and the second end 12 is an end closer to the lips of the user.

[0020] In this embodiment, the sealing part 20 is used to seal the first end 11 of the tube 10 to prevent the smoke generating part 30 from falling off from the first end 11. The sealing part 20 is made of food grade material and has a weight of 10 to 50 g / m 2 Silk paper, 10~50g / m 2 Highly breathable paper and 45~105g / m 2 The sealing portion 20 may be one or more of, but is not limited to, any of the above-mentioned butter papers. Specifically, the sealing portion 20 is formed by first adhering an edible grade material to the end surface of the tube 10 near the first end 11 with an adhesive, and then cutting the edible grade material along the outer contour of the tube 10. The sealing portion 20 may be formed by cutting using, but is not limited to, a die punching, a cutting tool punching, or a laser cutting.

[0021] In this embodiment, the smoke generating unit 30 includes an aerosol-generating substrate (for example, at least one of smoke generating particles or smoke generating sheets). The material of the aerosol-generating substrate includes tobacco or a non-tobacco herb unit. When the aerosol-generating substrate includes a non-tobacco herb unit, the aerosol-generating substrate does not generate harmful substances such as tar and nicotine, and the heated herb unit does not burn and pollute the surrounding environment, and does not affect the surrounding people, thereby ensuring the health of the person smoking the non-combustion cartridge 1 and the surrounding people. In addition, when the herb unit in the aerosol-generating substrate includes a material of Chinese herbal medicine (for example, ginseng, Tianma), smoking the non-combustion cartridge 1 can have a better health function. In addition, the loading length L3 formed by the smoke generating unit 30 being accommodated in the tube body 10 satisfies 13 mm≦L3≦18 mm.

[0022] In this embodiment, the cooling section 40 is accommodated in the tube 10 and is provided adjacent to the smoke generating section 30. The cooling section 40 is used to cool the aerosol generated by heating the smoke generating section 30. In one embodiment, the cooling section 40 is provided at a distance from the smoke generating section 30. In another embodiment, the cooling section 40 abuts against the smoke generating section 30.

[0023] In this embodiment, the filter 50 is housed in the tube 10 and disposed at the second end 12. The filter 50 is an edible porous and fluffy material such as polylactic acid (PLA). Specifically, the filter 50 is manufactured by an extrusion molding process. The outer diameter D2 of the filter 50 is larger than the inner diameter D0 of the tube 10 so that the filter 50 and the tube 10 form an interference fit to fix the filter 50 to the second end 12. Specifically, D2 satisfies 6.5 mm≦D2≦7 mm. Furthermore, the end face of the filter 50 away from the first end 11 is flush with the end face of the tube 10 near the second end 12.

[0024] Furthermore, the filtering section 50 is provided at a distance from the cooling section 40 to form a receiving cavity 60. The receiving cavity 60 is used to receive the aerosol generated by the heating of the smoke generating section 30. The aerosol generated by the heating of the smoke generating section 30 flows through the cooling section 40 to be cooled, then flows into the receiving cavity 60, gathers in the receiving cavity 60, and finally passes through the filtering section 50 to be inhaled by the user. Since the aerosol gathers in the receiving cavity 60 to form a certain concentration of aerosol, the concentration of the aerosol passing through the filtering section 50 can be increased, i.e., the concentration of the aerosol inhaled by the user can be increased.

[0025] In summary, the embodiment of the present application provides a heating and non-combustion cartridge 1. The heating and non-combustion cartridge 1 includes a tube 10, a sealing section 20, a smoke generating section 30, a cooling section 40, and a filtering section 50. The tube 10 has a first end 11 and a second end 12 arranged back to back. The sealing section 20 is used to seal the first end 11. The smoke generating section 30 is accommodated in the tube 10 and is adjacent to the first end 11. The cooling section 40 is accommodated in the tube 10 and is adjacent to the smoke generating section 30. The filtering section 50 is accommodated in the tube 10 and is arranged at the second end 12. The filtering section 50 and the cooling section 40 are spaced apart to form a receiving cavity 60. The aerosol generated by heating the smoke generating section 30 is collected in the storage cavity 60, so that a certain concentration of aerosol is formed in the storage cavity 60, increasing the concentration of the aerosol inhaled by the user. Therefore, the heating and non-combustion type cartridge 1 of the present application can increase the inhalation concentration of the aerosol.

[0026] Referring again to FIG. 3, in this embodiment, the ratio of the length L1 of the accommodating cavity 60 to the length L0 of the tube 10 in the direction from the first end 11 to the second end 12 is 30%≦L1 / L0≦35%.

[0027] In this embodiment, the receiving cavity 60 needs to have a length to provide enough space to receive the aerosol so as to increase the concentration of the aerosol. When the length L0 of the tube 10 is maintained at a constant length, the length L1 of the receiving cavity 60 affects the loading length L2 of the smoke generating part 30, that is, if the length L1 of the receiving cavity 60 is too large, the loading length L3 of the smoke generating part 30 is too small, so that the amount of smoke generated by the smoke generating part 30 is affected, and the smoking experience of the heating non-combustion cartridge 1 is reduced. Therefore, the receiving cavity 60 needs to be maintained at an appropriate length. Specifically, in the direction from the first end 11 to the second end 12, the ratio of the length L1 of the receiving cavity 60 to the length L0 of the tube 10 is 30%≦L1 / L0≦35%. This allows the storage cavity 60 to contain the aerosol and increase the inhalation concentration of the aerosol, while leaving sufficient space in the tube 10 for loading the smoke generating unit 30 to ensure the amount of smoke generated by the smoke generating unit 30.

[0028] 4, 5 and 6, Fig. 4 is a schematic cross-sectional view of another embodiment of the heating non-combustion cartridge according to the embodiment of Fig. 1 taken along line AA, Fig. 5 is a schematic view showing the structure of the cooling part in the heating non-combustion cartridge according to the embodiment of Fig. 4, and Fig. 6 is a schematic cross-sectional view of the cooling part in the heating non-combustion cartridge according to the embodiment of Fig. 5 taken along line BB. In this embodiment, the cooling part 40 has ventilation grooves 41 evenly distributed on its outer periphery. The ventilation grooves 41 penetrate the cooling part 40 in the direction from the first end 11 to the second end 12, and the ventilation grooves 41 communicate with the receiving cavity 60.

[0029] In this embodiment, the cooling section 40 has a plurality of ventilation grooves 41 evenly distributed around its circumference. The plurality of ventilation grooves 41 are used to increase the breathability of the cooling section 40, so that the aerosol generated by the heating of the smoke generating section 30 can pass through the cooling section 40 better. Specifically, the plurality of ventilation grooves 41 form a passage with the inner wall of the tube body 10, so that the aerosol can pass through the passage. When the smoke generating section 30 includes a granular aerosol generating substrate, i.e., smoke particles, the inner diameter of the ventilation groove 41 is smaller than the outer diameter of a single smoke particle. This prevents the smoke particles from passing through the ventilation groove 41 and falling onto other structures in the heating non-combustion cartridge 1, thereby preventing the use of the heating non-combustion cartridge 1 from being hindered. Specifically, in a given cross-sectional direction, the maximum width W of the ventilation groove 41 satisfies 0.8 mm≦W≦1.2 mm, and the depth H of the ventilation groove 41 satisfies 0.5 mm≦H≦0.6 mm. The predetermined cross-sectional direction is perpendicular to the direction from the first end 11 to the second end 12.

[0030] 7, 8 and 9, FIG. 7 is a schematic diagram of a cross section along line AA in a further embodiment of the heating non-combustion cartridge according to the embodiment of FIG. 1, FIG. 8 is a schematic diagram showing the structure of the heating non-combustion cartridge according to the embodiment of FIG. 7 in a first state, and FIG. 9 is a schematic diagram showing the structure of the heating non-combustion cartridge according to the embodiment of FIG. 7 in a second state. In this embodiment, the cooling section 40 has a first storage space 42 and a second storage space 43 provided back to back in a direction from the first end 11 to the second end 12. The first storage space 42 is provided closer to the smoke generating section 30 than the second storage space 43. The smoke generating section 30 can enter the first storage space 42. The second storage space 43 is in communication with the storage cavity 60.

[0031] In this embodiment, the first storage space 42 is used to provide a movement space for the smoke generating part 30. This prevents the following problem, that is, when the smoke generating part 30 is pressed, the density of the smoke generating part 30 increases, and the air gap inside the smoke generating part 30 decreases, which increases the inhalation resistance of the heating non-combustion cartridge 1 and affects the use of the user. Specifically, when the heating non-combustion cartridge 1 is to be heated, the heating non-combustion cartridge 1 is inserted into the smoking tool so that the heating part (e.g., heating needle or heating sheet, etc.) in the smoking tool is inserted into the smoke generating part 30. Since the heating part has a certain volume, it can be pressed against the smoke generating part 30, and when the smoke generating part 30 is pressed, a part of the smoke generating part 30 enters the first storage space 42, which partially fills or completely fills the first storage space 42, thereby preventing the aerosol-generating substrate from being pressed and causing excessive inhalation resistance. Specifically, the volume of the first storage space 42 is 30 mm 3 ~35mm 3 , and the first accommodation space 42 can provide sufficient space for the movement of the smoke generating section 30.

[0032] In this embodiment, when the manufacturing of the heating non-combustion cartridge 1 is completed, the heating non-combustion cartridge 1 is in a first state (see FIG. 8), and the entire smoke generating portion 30 is outside the first storage space 42. When the heating non-combustion cartridge 1 is inserted into a smoking device, the heating non-combustion cartridge 1 is in a second state (see FIG. 9), and a part of the smoke generating portion 30 enters the first storage space 42, partially filling or completely filling the first storage space 42. Note that, although FIG. 9 illustrates that a part of the smoke generating portion 30 enters the first storage space 42 and partially fills the first storage space 42, the amount of the smoke generating portion 30 that enters the first storage space 42 is not limited. It should also be noted that during the manufacturing of the heating non-combustion cartridge 1, for example, due to a processing error or transportation between processing steps, a part of the smoke generating portion 30 may enter the first storage space 42, and the heating non-combustion cartridge 1 may be in the second state. It should be noted that when the heat-and-non-combustion cartridge 1 is not inserted into a smoking device, due to reasons such as transportation or external impact, a part of the smoke-producing section 30 may enter the first accommodating space 42, and the heat-and-non-combustion cartridge 1 may be in the second state. Thus, the first state only means that the smoke-producing section 30 is entirely outside the first accommodating space 42, and the second state only means that a part of the smoke-producing section 30 enters the first accommodating space 42. As can be understood, the first state and the second state do not limit the use state of the heat-and-non-combustion cartridge 1.

[0033] It should be noted that the second accommodation space 43 may be the same as or different from the first accommodation space 42. However, the second accommodation space 43 has the same function as the first accommodation space 42. That is, in another embodiment, when the orientation of the cooling section 40 is opposite to that shown in FIG. 7, the second accommodation space 43 is provided adjacent to the smoke generating section 30 more than the first accommodation space 42, and the smoke generating section 30 can enter the second accommodation space 43, and the first accommodation space 42 communicates with the accommodation cavity 60. Here, the volume of the second accommodation space 43 is 30 mm 3 ~35mm 3 It is.

[0034] In addition, when the first accommodating space 42 and the second accommodating space 43 are the same, the thickness of the structure of the cooling section 40 can be made uniform, which can avoid shrinkage deformation during the manufacture of the cooling section 40 and is helpful in controlling the size of each part of the cooling section 40.

[0035] 10, which is a schematic cross-sectional view taken along line AA in a further embodiment of the heating and non-combustion type cartridge according to the embodiment of FIG 1. In this embodiment, the cooling section 40 further has a vent hole 44, which communicates with the first storage space 42 and the second storage space 43.

[0036] In this embodiment, the cooling section 40 further has a vent hole 44, which communicates with the first storage space 42 and the second storage space 43. The vent hole 44 is used to increase the breathability of the cooling section 40, so that the aerosol generated by the heating of the smoke generating section 30 can pass through the cooling section 40 better. When the smoke generating section 30 includes a granular aerosol generating substrate, i.e., smoke particles, the inner diameter of the vent hole 44 is smaller than the outer diameter of a single smoke particle. This prevents the smoke particles from passing through the vent hole 44 and falling onto other structures in the heating non-combustion cartridge 1, thereby preventing the use of the heating non-combustion cartridge 1 from being hindered. Specifically, the inner diameter D3 of the vent hole 44 satisfies 0.6 mm≦D3≦1 mm.

[0037] 11 and 12, Fig. 11 is a schematic diagram showing the structure of the cooling part in the heating non-combustion cartridge according to the embodiment of Fig. 10, and Fig. 12 is a schematic diagram of a cross section along line CC of the cooling part in the heating non-combustion cartridge provided in Fig. 11. In this embodiment, the ratio of the sum of the cross-sectional area S1 of the ventilation groove 41 in a predetermined cross-sectional direction and the cross-sectional area S2 of the ventilation hole 44 in a predetermined cross-sectional direction to the cross-sectional area S0 of the cooling part 40 in a predetermined cross-sectional direction is 15%≦(S1+S2) / S0≦20%. The predetermined cross-sectional direction is perpendicular to the direction from the first end 11 to the second end 12.

[0038] In this embodiment, the cross section of the ventilation groove 41, the cross section of the ventilation hole 44, and the cross section of the cooling part 40 in a certain cross-sectional direction are shown in FIG. 12. In order for the heated non-combustion cartridge 1 to have a suitable inhalation resistance, the ventilation groove 41 and the ventilation hole 44 need to have a suitable size. If the size of the ventilation groove 41 and the ventilation hole 44 is too large, the inhalation resistance of the heated non-combustion cartridge 1 will be too small, which will affect the smoking experience of the user. If the size of the ventilation groove 41 and the ventilation hole 44 is too small, the inhalation resistance of the heated non-combustion cartridge 1 will be too large, which will also affect the smoking experience of the user. In addition, if the size of the ventilation groove 41 and the ventilation hole 44 is too small, the concentration of the inhalable aerosol in the heated non-combustion cartridge 1 will be too low. Therefore, the ventilation groove 41 and the ventilation hole 44 need to have a suitable size. Specifically, the ratio of the sum of the cross-sectional area S1 of the ventilation groove 41 in the predetermined cross-sectional direction and the cross-sectional area S2 of the ventilation hole 44 in the predetermined cross-sectional direction to the cross-sectional area S0 of the cooling portion 40 in the predetermined cross-sectional direction is 15%≦(S1+S2) / S0≦20%. The predetermined cross-sectional direction is perpendicular to the direction from the first end 11 to the second end 12. S1 is the sum of the cross-sectional areas of all the ventilation grooves 41 in the predetermined cross-sectional direction.

[0039] 1 and 13 again, Fig. 13 is a schematic diagram showing a cross-sectional structure of a cooling part in the heating and non-combustion type cartridge according to the embodiment of Fig. 10. In this embodiment, the outer diameter D1 of the cooling part 40 is larger than the inner diameter D0 of the tube 10, and the cooling part 40 and the tube 10 form an interference fit to fix the cooling part 40 to the tube 10.

[0040] In this embodiment, since the outer diameter D1 of the cooling part 40 is larger than the inner diameter D0 of the tube body 10, the cooling part 40 can form an interference fit with the tube body 10 to fix the cooling part 40 to the tube body 10. This allows the cooling part 40 to be disposed at a predetermined position of the tube body 10 and to support the tube body 10 while maintaining their relative positions. Specifically, the outer diameter D1 of the cooling part 40 satisfies 6.5 mm≦D1≦6.8 mm, and the inner diameter D0 of the tube body 10 satisfies 6.4 mm≦D0≦6.65 mm.

[0041] 1 and 13, in this embodiment, the cooling portion 40 has chamfered portions 45 at both ends, and the outer diameter of the cooling portion 40 at the chamfered portions 45 is smaller than the inner diameter of the tube 10.

[0042] In this embodiment, there are chamfered portions 45 at both ends of the cooling portion 40, and the outer diameter of the cooling portion 40 at the chamfered portion 45 is smaller than the inner diameter of the tube body 10. When the cooling portion 40 is loaded into the tube body 10, the chamfered portion 45 can assist and guide the loading. If the cooling portion 40 does not have the chamfered portion 45, or if the outer diameter of the cooling portion 40 at the chamfered portion 45 is equal to or larger than the inner diameter of the tube body 10, when the cooling portion 40 is loaded into the tube body 10, the cooling portion 40 will press the second end 12 and damage the tube body 10. Therefore, the outer diameter of the cooling portion 40 at the chamfered portion 45 is smaller than the inner diameter of the tube body 10, and the second end 12 of the tube body 10 can be prevented from being damaged when the cooling portion 40 is loaded into the tube body 10. Specifically, the length L4 of the chamfered portion 45 in the radial direction of the cooling portion 40 satisfies 0.6 mm≦L4≦1 mm. The angle of the chamfered portion 45 may be 30°, 45°, 60°, 75°, etc., but is not particularly limited.

[0043] 1 and 13, in this embodiment, the length L2 of the cooling portion 40 is greater than the outer diameter D1 of the cooling portion 40.

[0044] In this embodiment, the length L2 of the cooling section 40 is greater than the outer diameter D1 of the cooling section 40. This helps to identify the loading direction of the cooling section 40 before loading the cooling section 40 into the tube 10. If the length L2 of the cooling section 40 is equal to or less than the outer diameter D1 of the cooling section 40, it is difficult to control the length direction of the cooling section 40 to the same direction as the transport direction when transporting the cooling section 40, or a direction recognition mechanism for identifying the direction of the cooling section 40 must be provided separately. This reduces the manufacturing efficiency of the heating non-combustion type cartridge 1 and is likely to cause loading errors of the cooling section 40. As a specific example of loading errors, both ends of the cooling section 40 are loaded into the tube 10 toward the inner wall of the tube 10. Therefore, the length L2 of the cooling section 40 needs to be greater than the outer diameter D1 of the cooling section 40, specifically, L2 satisfies 8 mm≦L2≦10 mm, and D1 satisfies 6.5 mm≦D1≦6.8 mm.

[0045] Furthermore, in one embodiment, the material of the cooling section 40 includes at least one of poly(ether-ether-ketone) (PEEK), polyphenylene sulfone resins (PPSU), poly(ethylene imine) (PEI), polyamide (PA), polyformaldehyde (POM), or silica gel.

[0046] In this embodiment, the material of the cooling part 40 is food-grade plastic or silica gel, etc., and has excellent heat resistance. Specifically, the heat resistance temperature of the cooling part 40 is 270°C to 400°C. When the aerosol generated by the heating of the smoke generating part 30 passes through the cooling part 40, the cooling part 40 can absorb the heat of the aerosol, and a good cooling effect can be obtained. Specifically, the material of the cooling part 40 may be one or more of PEEK, PPSU, PEI, PA, POM, or silica gel, but is not limited thereto. When the material of the cooling part 40 is a plastic material, the cooling part 40 is manufactured by an injection molding process. When the material of the cooling part 40 is a silica gel material, the cooling part 40 is manufactured by a hot press molding process.
