[0018] An embodiment of the present application provides a heat-non-combustion cartridge 1. Referring to FIGS. 1, 2, and 3, FIG. 1 is a schematic diagram showing the structure of a heat-non-combustion cartridge according to an embodiment of the present application, FIG. 2 is an exploded perspective view of the heat-non-combustion cartridge according to the embodiment of FIG. 1, and FIG. 3 is a schematic cross-sectional view of the embodiment of the heat-non-combustion cartridge according to the embodiment of FIG. 1 taken along line AA. In this embodiment, the heat-non-combustion cartridge 1 includes a tube 10, a sealing section 20, a smoke-emitting 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-emitting section 30 is housed within the tube 10 and is located adjacent to the first end 11. The cooling section 40 is housed within the tube 10 and is located adjacent to the smoke-emitting section 30. The filtering section 50 is housed within the tube 10 and is located at the second end 12. The filtering section 50 and the cooling section 40 are spaced apart to form 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 food-grade material, and has a density of 50 to 200 g / m 2 White paperboard and 50~200g / m 2The tube 10 may be made of one or more of the following kraft paper materials, but is not limited to these. In one embodiment, the tube 10 is manufactured by flat-winding a food-grade material. Specifically, the tube 10 is manufactured by flat-winding two or three layers of food-grade material. In another embodiment, the tube 10 is manufactured by diagonally winding a food-grade material. Specifically, the tube 10 is manufactured by diagonally winding two or three layers of food-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 heat-and-burn cartridge 1 is used by a user, the first end 11 of the tube 10 is the end farthest from the user's lips, and the second end 12 is the end closest to the user's lips.

[0020] In this embodiment, the sealing part 20 is used to seal the first end 11 of the tube body 10 to prevent the smoking 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 the following types: butter paper, but is not limited to these. Specifically, the sealing portion 20 is formed by first adhering a food-grade material to the end surface of the tube 10 near the first end 11 with an adhesive, and then cutting the food-grade material along the outer contour of the tube 10. The sealing portion 20 may be formed by cutting using a die punching, a blade punching, a laser cutting, or the like, but is not limited to these methods.

[0021] In this embodiment, the smoke-generating unit 30 includes an aerosol-generating substrate (e.g., at least one of smoke-generating particles or a smoke-generating sheet). 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 produce harmful substances such as tar or nicotine. Furthermore, the heated herb unit does not burn, polluting the surrounding environment and affecting nearby people, thereby ensuring the health of the smoker of the heat-not-burn cartridge 1 and those around them. In addition, if the herb unit in the aerosol-generating substrate includes ingredients from traditional Chinese medicines (e.g., ginseng or tianshe), smoking the heat-not-burn cartridge 1 can have better health benefits. Furthermore, the loading length L3 formed when the smoke-generating unit 30 is housed within the tube body 10 satisfies the relationship 13 mm≦L3≦18 mm.

[0022] In this embodiment, the cooling section 40 is housed within the tube 10 and is provided adjacent to the smoke generating section 30. The cooling section 40 is used to cool the aerosol generated when the smoke generating section 30 is heated. 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 is provided at the second end 12. The filter 50 is made of a porous, fluffy, food-grade material, such as polylactic acid (PLA). Specifically, the filter 50 is manufactured by extrusion molding. The outer diameter D2 of the filter 50 is larger than the inner diameter D0 of the tube 10 so that a tight fit is formed between the filter 50 and the tube 10 to secure the filter 50 to the second end 12. Specifically, D2 satisfies the relationship 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 unit 50 is spaced apart from the cooling unit 40 to form a receiving cavity 60. The receiving cavity 60 is used to receive the aerosol generated by heating the smoke generating unit 30. The aerosol generated by heating the smoke generating unit 30 passes through the cooling unit 40 to be cooled, then flows into the receiving cavity 60, collects in the receiving cavity 60, and finally passes through the filtering unit 50 to be inhaled by the user. Because the aerosol collects in the receiving cavity 60 and forms a certain concentration of aerosol, the concentration of the aerosol passing through the filtering unit 50 can be increased, i.e., the concentration of the aerosol inhaled by the user can be increased.

[0025] In summary, an embodiment of the present application provides a heat-and-burn cartridge 1. The heat-and-burn 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 housed within the tube 10 and is located adjacent to the first end 11. The cooling section 40 is housed within the tube 10 and is located adjacent to the smoke-generating section 30. The filtering section 50 is housed within the tube 10 and is located at the second end 12. The filtering section 50 and the cooling section 40 are spaced apart to form a housing 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 heat-and-non-combustion type cartridge 1 of the present application can increase the concentration of the aerosol inhaled.

[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 must have a length sufficient to provide a space for receiving the aerosol in order to increase the concentration of the aerosol. When the length L0 of the tube 10 is maintained constant, the length L1 of the receiving cavity 60 is the loading length of the smoke generating unit 30. L3 That is, if the length L1 of the receiving cavity 60 is too large, the loading length L3 of the smoke generating unit 30 will be too small, which will affect the amount of smoke generated by the smoke generating unit 30 and degrade the smoking experience of the heat-and-burn cartridge 1. Therefore, the receiving cavity 60 must 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 receiving cavity 60 to store aerosol and increase the aerosol inhalation concentration, while leaving enough space in the tube 10 for the smoke generating unit 30 to load and 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 taken along line AA of another embodiment of the heating non-combustion cartridge according to the embodiment of Fig. 1, Fig. 5 is a schematic view showing the structure of the cooling section in the heating non-combustion cartridge according to the embodiment of Fig. 4, and Fig. 6 is a schematic cross-sectional view taken along line BB of the cooling section in the heating non-combustion cartridge according to the embodiment of Fig. 5. In this embodiment, the cooling section 40 has ventilation grooves 41 evenly distributed around its periphery. The ventilation grooves 41 penetrate the cooling section 40 in the direction from the first end 11 to the second end 12, and the ventilation grooves 41 communicate with the accommodating cavity 60.

[0029] In this embodiment, the cooling section 40 has multiple ventilation grooves 41 evenly distributed around its periphery. The multiple ventilation grooves 41 are used to increase the breathability of the cooling section 40, allowing the aerosol generated by the heating of the smoke-generating section 30 to pass through the cooling section 40 more easily. Specifically, the multiple ventilation grooves 41 form a passage with the inner wall of the tube body 10, allowing the aerosol to pass through the passage. When the smoke-generating section 30 contains granular aerosol-generating substances, 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 within the heat-and-burn cartridge 1, thereby preventing the use of the heat-and-burn cartridge 1 from being interrupted. 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 cross-sectional view taken along line AA of a further embodiment of the heat-non-combustion cartridge according to the embodiment of FIG. 1, FIG. 8 is a schematic view showing the structure of the heat-non-combustion cartridge according to the embodiment of FIG. 7 in a first state, and FIG. 9 is a schematic view showing the structure of the heat-non-combustion cartridge according to the embodiment of FIG. 7 in a second state. In this embodiment, the cooling unit 40 has a first storage space 42 and a second storage space 43 arranged back to back in the direction from the first end 11 to the second end 12. The first storage space 42 is located closer to the smoke-emitting unit 30 than the second storage space 43. The smoke-emitting unit 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 accommodating space 42 is used to provide movement space for the smoke-generating unit 30. This prevents the following problem: when the smoke-generating unit 30 is compressed, the density of the smoke-generating unit 30 increases, reducing the air gap inside the smoke-generating unit 30, thereby increasing the inhalation resistance of the heat-and-burn cartridge 1 and affecting user comfort. Specifically, when heating the heat-and-burn cartridge 1, the heat-and-burn cartridge 1 is inserted into a smoking device so that a heating element (e.g., a heating needle or heating sheet) inside the smoking device is inserted into the smoke-generating unit 30. Because the heating element has a certain volume, it can be compressed against the smoke-generating unit 30. When the smoke-generating unit 30 is compressed, a portion of the smoke-generating unit 30 enters the first accommodating space 42, partially filling or completely filling the first accommodating space 42, thereby preventing the aerosol-generating substrate from being compressed and resulting in excessive inhalation resistance. Specifically, the volume of the first accommodating space 42 is 30 mm. 3 ~35mm 3 The first accommodation space 42 can provide sufficient space for the movement of the smoke generating unit 30.

[0032] In this embodiment, when the manufacture of the heat-and-burn cartridge 1 is completed, the heat-and-burn cartridge 1 is in a first state (see FIG. 8 ), with the entire smoke-producing portion 30 located outside the first accommodating space 42. When the heat-and-burn cartridge 1 is inserted into a smoking device, the heat-and-burn cartridge 1 is in a second state (see FIG. 9 ), with a portion of the smoke-producing portion 30 entering the first accommodating space 42, partially or completely filling the first accommodating space 42. Note that while FIG. 9 illustrates a case in which a portion of the smoke-producing portion 30 enters the first accommodating space 42 and partially fills it, the amount of the smoke-producing portion 30 that enters the first accommodating space 42 is not limited. It should be noted that during the manufacture of the heat-and-burn cartridge 1, for example, due to processing errors or transportation between processing steps, it is also possible for a portion of the smoke-producing portion 30 to enter the first accommodating space 42, causing the heat-and-burn cartridge 1 to be in the second state. It should be noted that when the heat-and-burn cartridge 1 is not inserted into a smoking device, a portion of the smoke-producing portion 30 may enter the first accommodating space 42 due to factors such as transportation or external impact, and the heat-and-burn cartridge 1 may be in the second state. Therefore, the first state only means that the entire smoke-producing portion 30 is outside the first accommodating space 42, and the second state only means that a portion of the smoke-producing portion 30 has entered the first accommodating space 42. As can be understood, the first and second states do not limit the use states of the heat-and-burn cartridge 1.

[0033] The second accommodating space 43 may be the same as or different from the first accommodating space 42. However, the second accommodating space 43 has the same function as the first accommodating space 42. That is, in another embodiment, when the cooling unit 40 is oriented in the opposite direction to that shown in FIG. 7, the second accommodating space 43 is disposed closer to the smoke generating unit 30 than the first accommodating space 42, and the smoke generating unit 30 can enter the second accommodating space 43, and the first accommodating space 42 communicates with the accommodating cavity 60. Here, the volume of the second accommodating space 43 is 30 mm 3 ~35mm 3 is.

[0034] In addition, if 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 manufacturing of the cooling section 40 and help control the size of each part of the cooling section 40.

[0035] 10, which is a schematic cross-sectional view taken along line AA of 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 ventilation hole 44, which communicates with the first accommodating space 42 and the second accommodating space 43.

[0036] In this embodiment, the cooling section 40 further includes a vent hole 44, which communicates with the first and second storage spaces 42 and 43. The vent hole 44 is used to improve the breathability of the cooling section 40, allowing the aerosol generated by the heating of the smoke-generating section 30 to pass through the cooling section 40 more easily. When the smoke-generating section 30 contains granular aerosol-generating substances, 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 within the heat-and-burn cartridge 1, thereby interfering with the use of the heat-and-burn cartridge 1. Specifically, the inner diameter D3 of the vent hole 44 satisfies the relationship 0.6 mm≦D3≦1 mm.

[0037] 11 and 12, Fig. 11 is a schematic diagram showing the structure of the cooling section in the heating and non-combustion cartridge according to the embodiment of Fig. 10, and Fig. 12 is a schematic diagram of a cross section of the cooling section in the heating and non-combustion cartridge shown in Fig. 11 taken along line CC. In this embodiment, 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 section 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.

[0038] In this embodiment, cross sections of the ventilation groove 41, the ventilation hole 44, and the cooling portion 40 in a predetermined cross-sectional direction are shown in FIG. 12 . The ventilation groove 41 and the ventilation hole 44 must be appropriately sized so that the heated non-combustion cartridge 1 has appropriate inhalation resistance. If the ventilation groove 41 and the ventilation hole 44 are too large, the inhalation resistance of the heated non-combustion cartridge 1 will be too low, which will affect the user's smoking experience. If the ventilation groove 41 and the ventilation hole 44 are too small, the inhalation resistance of the heated non-combustion cartridge 1 will be too high, which will also affect the user's smoking experience. In addition, if the ventilation groove 41 and the ventilation hole 44 are too small, the concentration of inhalable aerosol in the heated non-combustion cartridge 1 will be too low. Therefore, the ventilation groove 41 and the ventilation hole 44 must be appropriately sized. Specifically, the ratio of the sum of the cross-sectional area S1 of the ventilation grooves 41 in the predetermined cross-sectional direction and the cross-sectional area S2 of the ventilation holes 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, Fig. 13 is a schematic diagram showing the cross-sectional structure of the 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 tubular body 10, and the cooling part 40 and the tubular body 10 form an interference fit to fix the cooling part 40 to the tubular body 10.

[0040] In this embodiment, the outer diameter D1 of the cooling part 40 is larger than the inner diameter D0 of the tube 10, so that the cooling part 40 forms an interference fit with the tube 10, thereby fixing the cooling part 40 to the tube 10. This allows the cooling part 40 to be positioned at a predetermined position on the tube 10, and the relative positions of the cooling part 40 and the tube 10 to be maintained, thereby supporting the tube 10. 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 10 satisfies 6.4 mm≦D0≦6.65 mm.

[0041] Referring again to FIGS. 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 body 10 .

[0042] In this embodiment, the cooling section 40 has chamfers 45 at both ends, and the outer diameter of the cooling section 40 at the chamfers 45 is smaller than the inner diameter of the tube 10. The chamfers 45 assist and guide the cooling section 40 when it is inserted into the tube 10. If the cooling section 40 does not have chamfers 45, or if the outer diameter of the cooling section 40 at the chamfers 45 is equal to or larger than the inner diameter of the tube 10, the cooling section 40 will press against the second end 12 and damage the tube 10 when it is inserted into the tube 10. Therefore, the outer diameter of the cooling section 40 at the chamfers 45 is smaller than the inner diameter of the tube 10, which prevents damage to the second end 12 of the tube 10 when it is inserted into the tube 10. Specifically, the length L4 of the chamfers 45 in the radial direction of the cooling section 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 again, 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 identify the loading direction of the cooling section 40 before loading it into the tube 10. If the length L2 of the cooling section 40 is less than the outer diameter D1 of the cooling section 40, it would be difficult to control the length of the cooling section 40 to match the transport direction when transporting the cooling section 40, or a separate direction recognition mechanism would be required to identify the direction of the cooling section 40. This reduces the manufacturing efficiency of the non-heating combustion cartridge 1 and is likely to result in incorrect loading of the cooling section 40. A specific example of an incorrect loading is when 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 portion 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 cooling unit 40 is made of a material such as food-grade plastic or silica gel, which has excellent heat resistance. Specifically, the cooling unit 40 can withstand temperatures of 270°C to 400°C. When the aerosol generated by the heating of the smoke generating unit 30 passes through the cooling unit 40, the cooling unit 40 can absorb the heat of the aerosol, thereby achieving a good cooling effect. Specifically, the cooling unit 40 may be made of one or more of PEEK, PPSU, PEI, PA, POM, or silica gel, but is not limited thereto. When the cooling unit 40 is made of a plastic material, the cooling unit 40 is manufactured by an injection molding process. When the cooling unit 40 is made of a silica gel material, the cooling unit 40 is manufactured by a hot press molding process.

In this embodiment, the heat-non-combustion cartridge 1 includes a tube 10, a sealing section 20, a smoke-producing 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-producing section 30 is housed within the tube 10 and is located adjacent to the first end 11. The cooling section 40 is housed within the tube 10 and is located adjacent to the smoke-producing section 30. The filtering section 50 is housed 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 form a housing cavity 60. Furthermore, in this embodiment, the heat-and-non-combustion cartridge 1 further includes a packaging material 70 that encases the tube 10, with both ends of the packaging material 70 being flush with both ends of the tube 10.

[0048] In this embodiment, the packaging material 70 is used to wrap the tube 10 and mask dirt on the outer surface of the tube 10 and creases in the diagonal winding. Specifically, the material of the packaging material 70 is tip paper, and has a weight of 32 to 40 g / m 2 However, the present invention is not limited to this. Furthermore, by wrapping the tube 10 in a flat roll, the packaging material 70 has one end surface flush with the surface of the sealing portion 20 that is away from the first end 11, and the other end surface flush with the surface of the tube 10 that is closer to the second end 12. Specifically, the length L5 of the packaging material 70 satisfies 42 mm≦L5≦46 mm, and the outer diameter D4 of the packaging material 70 satisfies 7.15 mm≦D4≦7.3 mm.
