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 cartridges 1 should also be shipped. The smoking element 60 in the cartridge 1 is typically free of tobacco components, or contains a small amount of tobacco components. And the cartridge 1 is typically a non-combustible cartridge 1 that is heated, i.e. the smoking member 60 is heated, without burning the smoking member 60. 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 replace the traditional cigarette with the cartridge 1 to reduce the damage of the traditional cigarette to the user's body. The existing cartridge 1 has weak or single function and cannot meet the increasing requirements of users. For example, the cooling effect of the cartridge 1 still does not meet the user's requirements. Or the taste of the cartridge 1 at present is generally determined by the original smell of the smoking member 60. Or in addition to the flavourant flavour on the smoking member 60. However, there is a limit to the aroma, persistence and taste abundance of the smoke generating element 60 due to its increased capacity.

The cartridge 1 comprises a tubular body 40, a closure 50, a smoking element 60, a cooling element 10, a functional assembly 2, and a filter element 70, each of which will be described in detail in this embodiment.

The tube 40 is the main part of the cartridge 1 for mounting, securing and carrying the various components. The tube 40 has a receiving hole 41, and the tube 40 can penetrate through the two opposite ends to form the receiving hole 41. Alternatively, the tube 40 may be a solid tube 40 through which the receiving hole 41 is formed, or the tube 40 having the receiving hole 41 may be injection molded through an injection molding process, or the tube 40 having the receiving hole 41 may be formed by winding a material having a certain thickness.

Specifically, the edible material comprises, but is not limited to, white cardboard with the weight of 50-200g per square meter, kraft paper with the weight of 50-200g per square meter and the like.

Optionally, the length L4 of tube body 40 is 42-46mm, the outer diameter d4 is 6.9-7.1mm, and the inner diameter d4' is 6.4-6.65 mm.

The sealing member 50 is a member for sealing one of two open ends of the accommodating hole 41 of the tube 40, that is, the sealing member 50 seals the end surface of the tube 40 and shields the accommodating hole 41 to prevent the subsequent smoke generating member 60 from falling out, and also prevent the smoke generating member 60 from being collided by external force and being affected by damp.

Optionally, the material of the closure 50 includes food grade material. Further optionally, the food grade material includes, but is not limited to, one or more of silk tissue paper, highly breathable paper, and shea butter. Specifically, the edible material comprises, but is not limited to, 10-50 g/square meter cotton paper, 10-50 g/square meter high air permeability paper, 45-105 g/square meter beef tallow paper and the like.

Alternatively, the sealing member 50 has a circular shape with a diameter of 6.9 to 7.2mm, completely covers the accommodation hole 41, and is sealed to the end surface of the tube 40.

Alternatively, the closure 50 material may be die cut, knife cut, or laser cut to the desired configuration and then sealed to the tube 40. Or sealing the sealing member 50 on the tube 40, and punching the tube with a die, a knife die, or a laser to form the desired shape.

The smoking member 60 is a major component in the cartridge 1, and generates smoke for inhalation by the user, primarily by heating the smoking member 60. Alternatively, the smoking article 60 is prepared from various herbs. Optionally, the smoking member 60 is in the shape of a tablet or granulate.

A smoking element 60 may be disposed in the receiving hole 41 adjacent to the closure 50, i.e., abutting the closure 50. Optionally, the length of the smoking element 60 in the axial direction of the tube 40 is 13-18 mm. In the radial direction, the diameter of the smoking member 60 is 6.4-6.6 mm.

The cooling piece 10 is the main part of the cooling function in the cartridge 1, reduces the temperature of the smoke passing through the cooling piece 10, and avoids scalding the oral cavity of the user. The cooling member 10 has a structure with cooling holes 100, and specifically, the cooling holes 100 may be formed through two opposite sides, so as to reduce the temperature of the flue gas when the flue gas passes through the cooling holes 100. Alternatively, the cooling member 10 may be a solid cooling member 10 through which the cooling hole 100 is formed, or the cooling member 10 having the cooling hole 100 is injection-molded through an injection molding process, or the cooling member 10 having the cooling hole 100 is formed by winding a material having a certain thickness.

Optionally, the material of the cooling member 10 includes silica gel, food grade material, and 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). Specifically, the cooling member 10 includes, but is not limited to, 50-200 g/square meter of white cardboard, 50-200 g/square meter of kraft paper and the like.

Optionally, the length L1 of the cooling element 10 is 16-23mm, and the outer diameter d1 is 6-6.6 mm. Here, the "length" mentioned above refers to a dimension in the axial direction D1. In other words, the cooling member 10 has a dimension in its axial direction D1 of 16-23 mm. And the axial direction of the present application is denoted as D1 both before and after. The "outer diameter" mentioned above refers to the dimension in the radial direction D2. And the radial direction of the present application is denoted as D2 both before and after. And because the heatsink 10 has a thickness, when the heatsink 10 is apertured, the heatsink 10 is caused to have an outer peripheral sidewall and an inner peripheral sidewall. The outer peripheral side wall has the appearance of the cooling member 10, and the inner peripheral side wall is surrounded to form cooling holes 100. The temperature reducing member 10 has two dimensions in the radial direction, one being the dimension of the outer peripheral sidewall on opposite sides (i.e., the outer diameter) and the other being the dimension of the inner peripheral sidewall on opposite sides (i.e., the inner diameter). In other words, the cooling member 10 has a dimension of 6 to 6.6mm on opposite sides of the peripheral side wall in the radial direction thereof. And the same understanding can be made with respect to the length, outer diameter, inner diameter, axial direction, radial direction mentioned hereinafter in the present application, which will not be described in detail herein.

The cooling element 10 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 undersize of cooling tube then can lead to the resistance of suction flue gas too big, if the external diameter of cooling tube is too big, then can lead to the concentration undersize of flue gas in the cooling tube influences the taste of suction flue gas. Therefore, the outer diameter of the cooling pipe is 6-6.6mm, and the smoke concentration in the cooling piece 10 can be full under the condition 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 smoke into the cooling tube and drawing smoke out of the cooling element 10.

The functional assembly 2 comprises a carrier 20 and a functional part 30, the carrier 20 primarily serving to carry a subsequent functional part 30. The carrier 20 is a structure having a through hole 200. Specifically, the through hole 200 may be formed through the two opposite ends, so that the subsequent functional element 30 may be installed in the through hole 200. Alternatively, the carrier 20 may be a solid carrier 20 through which the through hole 200 is formed, or the carrier 20 having the through hole 200 is injection molded through an injection molding process, or the carrier 20 having the through hole 200 is formed by winding a material having a certain thickness, or is manufactured by pultrusion. In addition, the carrier 20 may be fixed within the cooling hole 100, i.e., the carrier 20 may remain stationary on the inner circumferential side wall of the cooling member 10. As to how the securing of the carrier 20 is specifically achieved, the present application will be described in detail below.

Alternatively, the material of the carrier 20 includes, but is not limited to, food grade polylactic acid, cellulose acetate, and the like.

Optionally, the ratio of the outer diameter d2 to the length L2 of the carrier 20 is (0.7-0.8): 1. the present embodiment may allow the outer diameter of the carrier 20 to be smaller than the length of the carrier 20, thereby allowing the carrier 20 to have a cylindrical elongated shape, which may facilitate the use of a vibratory pan arrangement to sequence the carriers 20 in a lengthwise direction during automated assembly. When the carriers 20 have wrong sorting, for example, parts of the carriers 20 are sorted in the outer diameter direction, and the operator can find and correct the sorting in time. If the ratio of the size to the length of the outer diameter is too large, for example, 1:1, the sorting error is not easy to be found by an operator, during assembly, the extension direction of the cooling hole 100 and the through hole 200 is vertical, smoke cannot enter and be discharged from the bearing member 20, and the loading action error is caused, so that the equipment stops working. If the ratio of the outer diameter to the length is too small, for example, 0.5:1, the outer diameter is too small and the carrier 20 cannot be fixed in the tube 40 during assembly.

Further optionally, the length L2 of the carrier 20 is 6-8mm, the outer diameter d2 is 5.8-6mm, and the inner diameter d2' is 3-4 mm. The inner diameter of the support member 20 is the actual passing size of the smoke, so that the inner diameter of 3-4mm not only allows the functional member 30 to be well fixed but also allows the smoke to pass smoothly, reducing the suction resistance. And the size of the inner and outer diameters also affects the size of the end face of the carrier 20, and thus the performance of the carrier 20 abutting against the filter element 70, and the present embodiment can achieve good abutting and fixing effects by the above-mentioned size.

The functional material 30 is used to realize various functions, in other words, various functions can be realized by using factors such as the shape, structure, material, and the like of the functional material 30. For example, if the functional element 30 is made of a heat absorbing material, such as metal or plastic, when the smoke is transmitted to the functional element 30, the heat absorbing material can absorb a large amount of heat, thereby further improving the cooling effect. If the functional element 30 has various flavors, the functional element 30 can be used to change the taste of the smoke, thereby enhancing, improving the quality of the smoke and the saturation, diversity and sustainability of the taste. If the functional component 30 has various traditional Chinese medicine or western medicine components, the functional component 30 can be used to make the smoke carry various traditional Chinese medicine or western medicine components, and when the user sucks the smoke, the traditional Chinese medicine or western medicine components can be sucked into the oral cavity, so that the smoke has the functions of health care and treatment.

The present embodiment is only schematically illustrated with the functional element 30 as flavouring element to modify the taste of the smoke. Optionally, the functional element 30 comprises a shell 31 and a functional portion 32 in a liquid or gaseous state disposed in the shell 31, wherein the shell 31 abuts against the carrier 20; the housing 31 can be broken when a predetermined external force is applied in a radial direction of the cooling member 10. The functional element 30 includes a housing 31 and a functional portion 32 disposed in the housing 31, and the functional portion 32 may be in a liquid state or a gaseous state. The housing 31 abuts the carrier 20 for fixation. And the housing 31 can be broken when a predetermined external force is applied in a radial direction of the cooling member 10. For example, when the user pinches the cooling element 10 along the radial direction of the cooling element 10 with a hand, when the squeezing force is larger than the preset external force, the housing 31 can be pinched to crush, break or break a hole 81 to expose the functional portion 32 therein, and when smoke passes through the functional portion 32, the smoke can be carried along with the functional portion 32, and the suction force of the user can also move the functional portion 32 to be finally inhaled into the mouth of the user. The application of the functional element 30 improves the taste and smell experience of the user. Further alternatively, the functional member 30 may be molded by extrusion blow molding, canning, or the like.

Optionally, when the shell 31 is broken, the liquid functional portion 32 can be adsorbed on the bearing member 20, so that the user can suck when smoke passes through the process and suck the smoke through the user, the functional portion 32 can be sucked into the mouth cavity more easily, the fragrance can be exerted from the filter cotton more continuously, the user experience is improved, and the liquid or gaseous functional portion 32 can be utilized to play a certain cooling role.

Optionally, the functional portion 32 includes food grade flavors including, but not limited to, a flavor blend of one or more of blueberry, apple, watermelon, mango, grape, and other fruit and vegetable flavors.

Alternatively, the functional element 30 may be spherical, ellipsoidal, or cylindrical in shape. When the functional element 30 is spherical in shape, the diameter d3 is 3-4 mm. When the functional element 30 is in the shape of an ellipsoid or a cylinder, the diameter d3 in the radial direction of the temperature reducing element 10 is 3-4mm, and the length L3 in the axial direction of the temperature reducing element 10 is 4-7 mm.

The filter element 70 may be used to filter some harmful substances and further reduce the temperature of the flue gas.

Alternatively, the material of the filter element 70 includes, but is not limited to, food grade polylactic acid, cellulose acetate, and the like. Further alternatively, when the material of the filter element 70 or the carrier 20 is polylactic acid, pultrusion may be used. Alternatively, the length L5 of the filter member 70 in the axial direction of the tube body 40 is 1-10 mm. The diameter d5 of the filter element 70 in the radial direction of the tubular body 40 is 6.5 to 7 mm.

Alternatively, when the tube 40 and the cooling member 10 are formed by winding, a flat winding or a diagonal winding can be adopted. The tube 40 and the cooling element 10 can be wound in the same manner or in different manners. If the paper is in a flat rolling mode, food-grade paper with single thickness and the range of 50-200g can be laminated together by 4-5, and glue with the width of 1-2 mm is coated on the overlapping opening of the last layer for fixation, so that the winding difficulty can be reduced. If the mode of oblique rolling is adopted, 3 layers of food grade paper can be adopted, and the thickness ratio from one side to the other side is 8: 10: 6, lap each other at 135 degrees +/-15 degrees and roll together in a spiral mode, and glue is fully coated between layers, so that the three layers can be firmly adhered together, and after the three layers leave the roll core, the oblique paper rolling tube has good stability, strength and roundness.

The smoke cartridge 1 provided by the embodiment can improve the cooling function of the cooling part 10 by adding the functional part 30, or the cooling part 10 has other functions besides the cooling function, such as flavoring, health care, treatment and the like, so that the functional types of the smoke cartridge 1 are improved, and the mouth feel and the suction effect of a user are improved.

Then, the carrier 20 is disposed in the receiving hole 41, and the functional element 30 abuts against the through hole 200 of the carrier 20, so that the functional element 30 can be mounted on the carrier 20 to limit the position of the functional element 30 and prevent the functional element 30 from moving freely.

And the arrangement of the functional assembly 2 between the cooling element 10 and the filter element 70 does not affect the normal use of the cooling element 10. In addition, the functional component 2 is arranged between the temperature reduction part 10 and the filter part 70, so that the functional part 30 is closer to the filter part 70, when the cartridge 1 is used, especially when the cartridge is used with a smoking set, the smoking part 60 is usually required to be inserted into the smoking set, and therefore, the functional part 30 is close to the filter part 70, so that the user can conveniently use the functional part 30, and the situation that the functional part 30 cannot be used by the user in the smoking set is prevented.

Referring to fig. 6 again, in the present embodiment, the dimension L4 of the tube 40 in the axial direction of the tube 40 is 42-46 mm. The size of the tube body 40 can be 42-46mm in the present embodiment, that is, the total length of all the components located in the tube body 40 is 42-46 mm. In other words, the total length of the smoking member 60, the temperature reducing member 10, the functional module 2, and the filter member 70 is 42 to 46 mm. The functional component 2 can be added to keep the length of the pipe body 40, namely the cigarette cartridge 1, to meet the use requirement range of a user, and the functional types of the cigarette cartridge 1 are improved.

Referring again to fig. 3 and 7, in the present embodiment, in the axial direction of the tube 40, the ratio of the dimension L2 of the carrier 20 to the dimension L5 of the filter element 70 is (1-4): 1.

in the present embodiment, the ratio of the length of the carrier 20 to the length of the filter 70 may be (1-4): 1. i.e., the length of the carrier 20 is greater than the length of the filter element 70, the filter element 70 is smaller as the carrier 20 is longer. It can also be understood that the present embodiment provides a space for adding the functional component 2 by reducing the length of the filter element 70 on the premise of ensuring that the total length of the tube body 40 and the cartridge 1 is kept unchanged.

Optionally, the total length of the filter member 70 and the carrier member 20 in the extending direction of the tube 40 is 8-10 mm. Further alternatively, the length of the carrier 20 may be understood to be the reduced length of the filter element 70. The longer the carrier 20, the smaller the filter 70.

Referring to fig. 2 to 3 again, in the present embodiment, in the axial direction of the tube 40, the ratio of the size of the cooling member 10 to the size of the carrier 20 is (2-4): 1.

in the present embodiment, the ratio of the length of the cooling member 10 to the length of the carrier member 20 is (2-4): 1, the length of the cooling element 10 is greater than the length of the carrier element 20, so that the cooling effect of the cooling element 10 is ensured. It can also be understood that this embodiment guarantees that body 40, cartridge 1 total length keep unchangeable under the prerequisite, provides the space through reducing the length that filters 70 and add functional component 2, and the length of cooling piece 10 still keeps unchangeable, makes the memory space of cooling function and smog not influenced from the taste that does not influence the user. In addition, the difficulty of retrofitting production equipment can be reduced by reducing the length of the filter element 70 without changing the length of the temperature reducing member 10, thereby reducing the cost of retrofitting.

Referring to fig. 8, fig. 8 is a schematic partial structure diagram of a cartridge according to an embodiment of the present application. In this embodiment, the cooling member 10 is provided with a cooling hole 100 communicating the receiving hole 41 with the through hole 200, the cartridge 1 further includes a ventilation sealing portion 80 fixed to one side of the cooling member 10, the ventilation sealing portion 80 covers the cooling hole 100, the ventilation sealing portion 80 abuts against the smoking member 60, and the other side of the cooling member 10 abuts against the carrier 20.

It is also possible for the cartridge 1 to include a breathable seal 80 secured to one side. When the ventilation sealing portion 80 shields the cooling hole 100, the sealing effect can be achieved, and the ventilation effect can be achieved because the ventilation sealing portion 80 has a ventilation function due to the material of the ventilation sealing portion 80, or at least one hole 81 is formed in the ventilation sealing portion 80, so that the ventilation function is achieved, and the smoke of the smoking piece 60 can enter the cooling piece 10 through the ventilation sealing portion 80.

Optionally, the material of the breathable sealing portion 80 comprises food grade material. Further optionally, the food grade material includes, but is not limited to, one or more of silk tissue paper, highly breathable paper, and shea butter.

Alternatively, the material of the vent seal 80 may be die cut, knife cut, or laser cut to the desired shape and then bonded to the heat sink 10. Or the air-permeable sealing part 80 is firstly bonded on the cooling part 10, and then the required shape is cut by die punching, knife die punching or laser.

The ventilation sealing portion 80 of the present embodiment can prevent the smoke generating member 60 from entering the cooling member 10, but allows the smoke to pass through, and for the other side of the cooling member 10, since the supporting member 20 also has the through hole 200, and the supporting member 20 has a certain wall thickness, the supporting member 20 is not disposed in all the regions in the radial direction, and only the supporting members 20 are disposed on the opposite sides, so the ventilation sealing portion 80 is not required to be disposed on the other side of the cooling member 10, and the supporting member 20 can be supported only by using the wall thickness of the cooling member 10. Therefore, the other side is not required to be provided with the ventilating sealing part 80 subsequently, the ventilating area of the cooling piece 10 can be increased, the smoke can flow more smoothly, and the suction resistance is reduced. In addition, the breathable sealing part 80 is not required to be arranged, so that raw materials can be saved, the preparation difficulty is reduced, and the cost is reduced.

Optionally, the surface of the carrier 20 facing away from the tube 40 protrudes beyond the surface of the cooling element 10 facing away from the tube 40, so that on the basis of the fixing function 30, the smoke flow rate can be controlled, which is equivalent to controlling the smoke amount.

Further alternatively, referring to fig. 1 again, in the present embodiment, in the radial direction of the tube 40, the ratio of the wall thickness of the carrier 20 to the wall thickness of the cooling member 10 is (1.75-6): 1. when the ratio of the wall thickness of the carrier 20 to the wall thickness of the temperature reducing member 10 is in the above range, the functional member 30 can be fixed and the flow rate of the smoke can be controlled at the same time.

Referring to fig. 9, fig. 9 is a schematic structural view of a cartridge according to another embodiment of the present application. In this embodiment, an end portion of the filter member 70 close to the sealing member 50 is disposed in the through hole 200. This embodiment allows a portion of the filter element 70 to extend into the through-hole 200, thereby increasing the length of the filter element 70 and improving the filtering effect of the filter element 70.

Please refer to fig. 3-4, fig. 10-11 again. Fig. 10 is a schematic structural diagram of a functional element according to an embodiment of the present application. Fig. 11 is an exploded view of fig. 10. In the present embodiment, the carrier 20 is in interference fit with the function 30, and the ratio of the inner diameter d2' of the carrier 20 to the dimension d3 of the function 30 in the radial direction of the carrier 20 is (0.9-0.95): 1, the supporting member 20 and the functional member 30 are ensured to maintain a certain interference, and the functional member 30 is ensured to be fixed on the supporting member 20, the cooling member 10 is not extruded and deformed outwards, and the functional member 30 is not damaged in the above range. If the inner diameter of the carrier 20 and the functional element 30 are too small, for example less than 0.9:1, in the radial direction of the carrier 20, the carrier 20 cannot be fixed to the tube 40, and the functional element 30 is damaged due to the too small inner diameter. And when the functional member 30 is broken, the inner diameter of the supporting member 20 is reduced by the reverse pressing force of the inner wall of the tube 40, which increases the suction resistance. If the inner diameter of the carrier 20 and the dimension of the functional element 30 in the radial direction of the carrier 20 are too small, for example greater than 0.95: 1. The carrier 20 cannot be installed in the tube 40, and the functional element 30 cannot be installed in the carrier 20 by interference fit.

Of course, in other embodiments, the functional element 30 may be adhered to the inner side wall of the carrier 20 by, for example, adhesion, so that the functional element 30 is fixed on the carrier 20.

Referring to fig. 10-11 again, in the present embodiment, a groove 21 is formed on an inner side wall of the carrier 20, and a part of the functional element 30 is disposed in the groove 21.

In the present embodiment, on the basis of the interference fit, the groove 21 is provided on the inner side wall of the carrier 20, and part of the functional member 30 is provided in the groove 21. The groove 21 can be utilized to relieve the pressing force due to the interference fit, thereby preventing the carrier 20 from being deformed by pressing, which may also cause other components such as the tube body 40 to be deformed, and eventually cause a problem of uneven shape, such as local bulging of the tube body 40 in the radial direction. In addition, the presence of the groove 21 may further define the position of the functional element 30 within the carrier 20, improving the accuracy of the position of the functional element 30 within the carrier 20.
