The traditional cigarette contains a large amount of tar and nicotine, and seriously harms the physical health of users. With the increasing health demands of users, the cigarette cartridges should be shipped. The smoking element in a cartridge typically contains no or a small amount of tobacco components. And the cartridges are typically non-combustible cartridges that are heated, i.e. the smoking element is heated without burning the smoking element. Therefore, harmful substances such as tar and nicotine can be avoided, the surrounding environment can not be polluted, the influence on surrounding people can not be caused, and the health of smokers and the surrounding people can be guaranteed.

Based on the above differences, more and more users now replace traditional cigarettes with cartridges to reduce the damage that traditional cigarettes cause to the user's body. The functional components in the cartridge have a variety of functions, such as cooling, flavoring, health care, treatment, and the like. However, the existing smoke cartridge has poor air permeability of functional components, so that the smoke cartridge has large suction resistance and cannot meet the increasing requirements of users. For example, the taste of current cartridges is often determined by the original odor of the smoking element. Or in addition to the flavorant on the smoking article.

And the axial direction in the present application is denoted by D1 both before and after. The above-mentioned "outer diameter" refers to a dimension in the radial direction D2. And the radial direction in the present application is denoted by D2 both before and after. And since the tube 11 has a thickness, when the tube 11 is perforated, the tube 11 is caused to have an outer circumferential side wall and an inner circumferential side wall. The outer peripheral side wall has an outer appearance surface of the pipe body 11, and the inner peripheral side wall is surrounded to form an accommodating space. The pipe body 11 has two dimensions in the radial direction, one being the dimension of the opposite sides of the outer peripheral side wall (i.e., the outer diameter) and the other being the dimension of the opposite sides of the inner peripheral side wall (i.e., the inner diameter). In other words, the tubular body 11 has a dimension of 6.9 to 7.1mm on opposite sides of the outer peripheral side wall and a dimension of 6.4 to 6.8mm on opposite sides of the inner peripheral side wall in the radial direction thereof. And the length, the outer diameter, the inner diameter, the axial direction and the radial direction mentioned below in the present application can be understood the same, and the detailed description will not be provided in the present application.

The sealing member 12 is a member for sealing one of two open ends of the accommodating space of the tube 11, that is, the sealing member 12 is sealed on the first surface of the tube 11 and shields the accommodating space, and one end of the accommodating space is close to the smoke generating member 13, so that the sealing member 12 can prevent the subsequent smoke generating member 13 from falling out, and can also prevent the smoke generating member 13 from being affected by external force and being affected with damp.

Alternatively, the smoking member 13 is prepared from various herbs. Optionally, the smoking member 13 is in the shape of a sheet or a granulate.

The smoking member 13 may be disposed in the receiving space and adjacent to the closure member 12, i.e. abutting the closure member 12. Optionally, the length of the smoking element 13 in the axial direction of the tube 11 is 13-18mm. The diameter of the smoking member 13 in the radial direction of the tube 11 is 6.4-6.6mm.

Referring to fig. 1 again, and fig. 3 to fig. 6, fig. 3 is a schematic perspective view of a cooling member according to an embodiment of the present disclosure. Fig. 4 is a schematic structural view of a cooling member according to another embodiment of the present application. Fig. 5 is a schematic structural view of a cartridge according to another embodiment of the present disclosure. Fig. 6 is a schematic structural view of a cartridge according to another embodiment of the present disclosure.

The cooling subassembly is the essential element who takes off cooling function in the cigarette bullet 1, through the temperature that reduces the flue gas in the cooling 14, avoids scalding user's oral cavity. The cooling member 14 has a structure with a cooling space, and specifically, can penetrate through the third surface and the fourth surface which are oppositely arranged, so as to form the cooling space, thereby reducing the temperature of the flue gas when the flue gas passes through the cooling space. The third surface is closer to the smoking piece 13 than the fourth surface. Alternatively, the cooling member 14 may be a solid cooling member 14, which forms the cooling space by penetrating through the solid cooling member 14, or the cooling member 14 having the cooling space is injection-molded by an injection molding process, or the cooling member 14 having the cooling space is formed by winding a material having a certain thickness.

Optionally, the cooling element 14 is made of silicone, polyetheretherketone (KEEP), polyphenylene sulfone (PPSU), polyetherimide (PEI), polyamide (PA), polyoxymethylene (POM), food grade material, or the like. The above-mentioned "food grade material" means that it can reduce or even not produce toxic or harmful substances to the human body or environment when heated. Further optionally, the food grade material includes, but is not limited to, one or more of white cardboard, kraft paper, polylactic acid (PLA). Still further optionally, the temperature reduction members 14 include, but are not limited to, white cardboard of 50 to 200 grams per square meter, kraft paper of 50 to 200 grams per square meter, and the like.

Optionally, the length L2 of the cooling member 14 is 8-10mm, and the outer diameter d3 is 6.5-6.75mm.

The cooling element 14 is designed in the size range, so that the cooling performance can be improved, and the concentration of smoke and the suction resistance during suction can be ensured. If the external diameter of cooling piece 14 is too little, then can lead to the resistance of smoking flue gas too big, if the external diameter of cooling piece 14 is too big, then can lead to the concentration of flue gas is too little in the cooling tube, influences the taste of smoking flue gas. Therefore, the outer diameter of the cooling piece 14 is 6.5-6.75mm, so that the smoke concentration in the cooling piece 14 is full under the condition of ensuring that the suction resistance is small. It should be noted that the resistance to suction means resistance to suction. Wherein the resistance to draw is the resistance encountered by drawing the flue gas into the cooling tube and drawing the flue gas out of the cooling member 14.

As shown in fig. 3, in one embodiment, a plurality of third ventilation grooves 141 communicating with the accommodating hole 111 are provided on the outer peripheral side of the cooling member 14, and the third ventilation grooves 141 penetrate the cooling member 14.

In the present embodiment, the third ventilation grooves 141 that penetrate the cooling material 14 in the extending direction of the accommodating hole 111 are additionally provided on the outer circumferential side of the cooling material 14, and it can be understood that the passage of the smoke through the cooling material 14 is increased. The cooling member 14 also has a cooling effect on the smoke in the third ventilation groove 141. Therefore, the third ventilation groove 141 is additionally arranged, so that the ventilation property of the cooling part 14 can be increased, the amount of smoke generated by cooling the cooling part 14 at the same time is increased, and the suction effect of a user is improved.

As shown in fig. 4, in one embodiment, the cooler 14 has a first receiving space 142 and a second receiving space 143 opposite to each other in the extending direction of the receiving hole 111, the first receiving space 142 is close to the smoking piece 13 relative to the second receiving space 143, and the smoking piece 13 can enter the first receiving space 142, and the second receiving space 143 is communicated with the receiving hole 111.

As shown in fig. 1, 5, and 6, the first receiving space 142 in the present embodiment is closer to the smoke generating member 13 than the second receiving space 143, and when the cartridge 1 is inserted into the smoking set, the smoke generating member 13 receives a pressing force from the outside, for example, the smoke generating member 13 is pressed by the smoking set or a heating member in the smoking set. At this time, the first accommodating space 142 may provide a moving space for the smoking member 13, so that at least part of the tobacco enters the first accommodating space 142, and the extrusion force applied to the smoking member 13 is relieved. In addition, for example, as shown in fig. 1, when the cartridge is just assembled, tobacco does not enter the first receiving space 142. For another example, as shown in fig. 5 and 6, there may be at least a portion of the smoking element 13 entering the first receiving space 142 during transport or handling by the user. And, the second accommodating space 143 can be used for storing the smoke, improving the smoke concentration in the cartridge 1, thereby improving the suction effect of the user.

Optionally, as shown in fig. 4, the cooling member 14 further includes a vent hole 144, the vent hole 144 penetrates through the cooling member 14 in the extending direction of the receiving hole 111, and the vent hole 144 communicates the first receiving space 142 and the second receiving space 143. The vent hole 144 of the present embodiment communicates the first receiving space 142 and the second receiving space 143, so that the smoke in the first receiving space 142 can be introduced into the second receiving space 143, thereby increasing the air permeability of the cartridge 1, reducing the suction resistance, and improving the suction effect of the user.

Referring to fig. 7 to 8, fig. 7 is a schematic perspective view of a functional assembly according to an embodiment of the present disclosure. Fig. 8 is a schematic structural diagram of a carrier according to an embodiment of the present disclosure. The functional module 15 comprises a bearing member 151 and a functional member 152, wherein the bearing member 151 is used for cooperating with the functional member 152 to provide the functional module 15 with various functions, such as cooling, flavoring, health care, treatment, etc. The shape of the carrier 151 in the present embodiment is not limited, and includes, but is not limited to, a cylinder, a rectangular parallelepiped, and the like. Optionally, the material of the carrier 151 includes silicone, hollow filter cotton, food grade silicone, food grade hollow filter cotton, and the like. When hollow filter cotton is used as the material of the carrier 151, the manufacturing cost can also be reduced.

The carrier 151 of the present embodiment is provided with first ventilation grooves 1512, and the first ventilation grooves 1512 are used to allow smoke to pass through the carrier 151, so as to improve the ventilation of the carrier 151, thereby improving the suction effect of the user. Alternatively, the carrier 151 may be a solid carrier 151 through which the through holes 1511 and the first air permeable grooves 1512 are formed, or the carrier 151 having the through holes 1511 and the first air permeable grooves 1512 are injection molded through an injection molding process, or the carrier 151 having the through holes 1511 and the first air permeable grooves 1512 are formed by winding a material having a certain thickness.

Optionally, the opening width of the first venting groove 1512 near the through hole 1511 is less than or equal to the opening width of the first venting groove 1512 far from the through hole 1511.

When the opening width of the first ventilation grooves 1512 near the through holes 1511 is smaller than the opening width of the first ventilation grooves 1512 far from the through holes 1511, that is, the interval between adjacent first ventilation grooves 1512 near the through holes 1511 is larger, so that the rigidity of the carrier 151 is larger. Meanwhile, the opening width far away from the through hole 1511 is large, so that the space of the first ventilation groove 1512 is increased while the hardness of the bearing 151 is ensured, and more smoke passes through, so as to improve the ventilation property of the bearing 151 and reduce the suction resistance. Therefore, by setting the opening width of the first ventilation grooves 1512, the hardness of the bearing member 151 can be improved to ensure that the hardness of the bearing member 151 meets the product requirement, and the ventilation property of the first ventilation grooves 1512 can be improved, so that the suction resistance of the bearing member 151 is reduced, and the suction effect of the user is improved.

When the opening width of the first ventilation groove 1512 near the through hole 1511 is equal to the opening width of the first ventilation groove 1512 far from the through hole 1511, it can also be understood that the distance between the side walls of the first ventilation groove 1512 near the two opposite sides of the through hole 1511 is equal to the distance between the side walls far from the two opposite sides of the through hole 1511. The first air-permeable grooves 1512 with consistent opening width are disposed on the supporting member 151, which not only reduces the manufacturing difficulty, but also ensures that the hardness of the supporting member 151 meets the product requirements.

Optionally, the bottom wall of the first ventilation groove 1512 is convex in a direction away from the through hole 1511. In the present embodiment, the bottom wall of the first ventilation groove 1512 protrudes in the direction away from the through hole 1511, which can also be understood as the bottom wall of the first ventilation groove 1512 protrudes in the direction away from the central axis of the first ventilation groove 1512, and the space of the first ventilation groove 1512 can be further increased, so that more smoke can pass through, thereby further improving the air permeability of the first ventilation groove 1512, reducing the suction resistance of the bearing 151, and improving the suction effect of the user.

Optionally, in a radial direction of the carrier 151, a size ratio of the through-hole 1511 to the carrier 151 is (1.8-3.8 mm): (6.3-7.0 mm). It is also understood that the ratio of the inner diameter to the outer diameter of the carrier 151 is (1.8-3.8 mm): (6.3-7.0 mm).

Alternatively, as shown in FIG. 8, the length L2 of the carrier 151 is 8.0-10.0mm, the outer diameter d3 is 6.3-7.0mm, and the inner diameter d4 is 1.8-3.8mm.

Designing the inner and outer diameters of the carrier 151 to the above-described ranges not only ensures the air permeability of the carrier 151 to improve the suction effect of the user, but also ensures the space where the first air-permeable grooves 1512 are provided, or the space of other components that engage with the carrier 151. If the ratio of the inner diameter to the outer diameter is too small, the space of the through hole 1511 is small, so that the space where the first ventilation groove 1512 can be disposed is small, which increases the manufacturing difficulty, or the space where other components are fitted to the carrier 151 is small, which results in poor adaptability; if the size ratio of the inner diameter to the outer diameter is too large, the concentration of smoke is too low, and the taste of the smoke to be sucked is affected. Thus, the ratio of the inner diameter to the outer diameter of the carrier 151 is (1.8-3.8 mm): (6.3-7.0 mm), the gas permeability of the silicon carrier can be ensured, so that the concentration of the smoke in the bearing member 151 is full, and the bearing member 151 can be ensured to have enough space to arrange the first gas-permeable grooves 1512 or other matching parts.

Optionally, the number of the first air-permeable grooves 1512 is 3-10.

Designing the number of the first ventilation grooves 1512 to be within the above range not only improves the ventilation but also ensures the concentration of smoke and the suction resistance during smoking. If the number of the first ventilation grooves 1512 is too small, the ventilation performance of the supporting member 151 may be poor, and the resistance to smoke suction may be too large, and if the number of the first ventilation grooves 1512 is too large, the smoke concentration may be too small, which may affect the taste of the smoke suction. Therefore, the number of the first air-permeable grooves 1512 is 3 to 10, which can ensure both the air permeability of the carrier 151 and the concentration of the smoke in the carrier 151 to be full under the condition of low suction resistance. It should be noted that the resistance to suction means resistance to suction. Wherein the resistance to draw refers to the resistance encountered by drawing smoke into the carriers 151 and drawing smoke out of the carriers 151.

Optionally, in a radial direction of the carrier 151, the first air-permeable grooves 1512 have an aspect ratio of (0.6-1.4 mm): (0.6-1.4 mm).

Optionally, the opening width of the first air-permeable grooves 1512 is 0.6-1.4mm and the opening depth of the first air-permeable grooves 1512 is 0.6-1.4mm in the radial direction of the carrier 151.

Designing the first air-permeable grooves 1512 to have the above-described size range not only improves air permeability to ensure the concentration of smoke and suction resistance during suction, but also ensures the hardness of the supporting member 151. If the depth and width of the first ventilation grooves 1512 are too small, the ventilation performance of the supporting member 151 is poor, and the resistance to smoke suction is too large; if the depth and width of the first ventilation grooves 1512 are too large, the hardness of the supporting member 151 is low, and the supporting member is easily damaged by external force, and the smoke concentration is too low, which affects the taste of the smoke to be sucked. Therefore, the opening width of the first air-permeable grooves 1512 is 0.6-1.4mm, and the opening depth of the first air-permeable grooves 1512 is 0.6-1.4mm, which not only ensures the air permeability of the carrier 151, but also ensures the hardness of the carrier 151 to meet the product requirement, and makes the concentration of smoke in the carrier 151 full under the condition of small suction resistance.

Referring to fig. 9, fig. 9 is a schematic perspective view of a carrier according to another embodiment of the present disclosure. When the carrier 151 is a silicone carrier 151, a plurality of second air permeation grooves 1513 communicating with the accommodating holes 111 are formed on the outer circumferential side of the carrier 151, and the second air permeation grooves 1513 penetrate through the carrier 151.

In this embodiment, the supporting member 151 is further provided with a second ventilating groove 1513, and the second ventilating groove 1513 penetrates through the supporting member 151, so that the smoke can penetrate through the supporting member 151 through the through hole 1511 and the first ventilating groove 1512, and can also penetrate through the supporting member 151 through the second ventilating groove 1513, so that the ventilation of the supporting member 151 can be further improved by adding the second ventilating groove 1513, and the suction effect of the user can be further improved.

Optionally, the bottom wall of the second air-permeable groove 1513 is convex in a direction away from the through hole 1511. In this embodiment, the bottom wall of the second air permeation groove 1513 protrudes in a direction away from the through hole 1511, which can also be understood as that the bottom wall of the second air permeation groove 1513 protrudes in a direction close to the central axis of the second air permeation groove 1513, when the second air permeation groove 1513 is impacted by external force, the bent bottom wall is beneficial to bearing larger external force, and the stability of the second air permeation groove 1513 is increased, especially when the silicone bearing member 151 is a cylinder.

Optionally, the number of the second air-permeable grooves 1513 is 25-35.

Designing the number of the second air-permeable grooves 1513 in the above range not only improves the air permeability to ensure the concentration of smoke and the suction resistance at the time of suction, but also ensures the hardness of the carrier 151. If the number of the second air-permeable grooves 1513 is too small, the air-permeable performance of the supporting member 151 is poor, and the resistance to smoke suction is too large; if the number of the second ventilating grooves 1513 is too large, the strength of the supporting member 151 is small, the supporting member is easily damaged by external force, and the concentration of smoke is too small, which affects the taste of the smoke to be sucked. Therefore, the number of the second air-permeable grooves 1513 is 25 to 35, which can ensure the air permeability of the bearing 151, ensure the hardness of the bearing 151 to meet the product requirement, and make the concentration of the smoke in the bearing 151 full under the condition of small suction resistance.

Designing the second air-permeable groove 1513 in the above-described size range not only improves air permeability to ensure the concentration of smoke and suction resistance at the time of suction, but also ensures the hardness of the carrier 151. If the depth and width of the second air-permeable groove 1513 are too small, the air-permeable performance of the supporting member 151 is poor, and the resistance to smoke suction is too large; if the depth and width of the second ventilating groove 1513 are too large, the strength of the bearing member 151 is small, and the bearing member is easily damaged by external force, and the smoke concentration is too small, which affects the taste of the smoke to be sucked. Therefore, the opening width of the second air-permeable groove 1513 is 0.2-0.5mm, and the opening depth of the second air-permeable groove 1513 is 0.2-0.4mm, which can ensure the air permeability of the bearing 151, ensure the hardness of the bearing 151 to meet the product requirement, and make the concentration of smoke in the bearing 151 full under the condition of small suction resistance.

When the bearing 151 is interference-fitted with the functional member 152, the tube body 11 has a pressing force on the second air-permeable groove 1513 of the bearing 151. At this time, at least a portion of the sidewall of the second airing groove 1513 is also subjected to a pressing force, thereby being deformed. The extrusion force extrudes the sidewall of the second air-permeable groove 1513, so that the sidewall of the second air-permeable groove 1513 protrudes towards the direction of the central axis far away from the second air-permeable groove 1513, the space of the second air-permeable groove 1513 is increased, the air permeability of the second air-permeable groove 1513 is further improved, the suction resistance of the bearing member 151 is reduced, and the suction effect of the user is improved. Therefore, the side wall of the second ventilating groove 1513 is a specific curved surface, so that the extrusion force can be relieved, the space of the second ventilating groove 1513 can be increased, and the air permeability of the second ventilating groove 1513 is further improved.

It is also understood that various functions may be implemented using factors such as the shape, structure, material, etc. of the functional element 152. For example, if the functional element 152 is made of a heat absorbing material, such as metal or plastic, when the smoke is transmitted to the functional element 152, the heat absorbing material can absorb a large amount of heat, thereby further improving the cooling effect. If the functional element 152 has various flavors, the functional element 152 can be utilized to change the flavor of the smoke, thereby enhancing, improving the quality of the smoke and the saturation, diversity and sustainability of the flavor.
