Traditional cigarettes contain a large amount of tar and nicotine, which seriously endanger the health of users. With the increasing health needs of users, Pod 1 also came into being. The smoking element 60 in the cartridge 1 usually does not contain tobacco components, or contains a small amount of tobacco components. And the pod 1 is usually a heat-not-burn pod 1 , that is, the smoking part 60 is heated without burning the smoking part 60 . In this way, harmful substances such as tar and nicotine can be avoided, and the surrounding environment will not be polluted, and the surrounding people will not be affected, so as to ensure the health of the smoker and the surrounding people.

Based on the above differences, more and more users are now using pods 1 to replace traditional cigarettes in order to reduce the damage caused by traditional cigarettes to the user's body. The cooling component 2 in the pod 1 usually acts to reduce the temperature of the smoke, preventing the smoke from being too high and causing the user's mouth to be scalded when smoking. However, the function of the cooling component 2 cannot meet the increasing demands of users at present. For example, the taste of the current pod 1 is usually determined by the original smell of the smoking part 60 . Or it can be obtained by adding food flavors and fragrances on the smoking part 60. However, subject to factors such as the capacity of the smoking piece 60, there are certain limitations in its aroma, persistence and richness of taste.

In view of this, in order to solve the above problems, the present application provides a cooling assembly 2 . Please refer to FIG. 1-FIG. 5 together. FIG. 1 is a schematic structural diagram of a cooling component in an embodiment of the present application. Fig. 2 is a schematic structural diagram of a cooling element in an embodiment of the present application. FIG. 3 is a schematic structural diagram of a carrier in an embodiment of the present application. FIG. 4 is a schematic structural diagram of functional components in an embodiment of the present application. FIG. 5 is a schematic structural diagram of functional components in another embodiment of the present application.

This embodiment provides a cooling component 2 , including a cooling component 10 , a bearing component 20 , and a functional component 30 . Wherein, the cooling element 10 has a first through hole 100 penetrating through the first end surface 101 and the second end surface 102 disposed opposite to each other. The carrier 20 has a second through hole 200 through the third end surface 201 and the fourth end surface 202 arranged opposite to each other, the carrier 20 is fixed in the first through hole 100, and the third end surface 201 is flush on the first end surface 101. The functional component 30 is at least partially fixed in the second through hole 200 .

The cooling component 2 mainly has the function of cooling, and can be applied to the pod 1, so as to reduce the temperature of the smoke passing through the cooling component 2 and avoid scalding the user's mouth. The cooling assembly 2 provided in this embodiment generally includes a cooling component 10 , a bearing component 20 , and a functional component 30 . Next, each component and the cooperation between each component will be described in detail.

The cooling element 10 is the main component of the cooling assembly 2 that performs the cooling function. The cooling element 10 has a structure with a first through hole 100. Specifically, the first through hole 100 can be formed through the oppositely disposed first end surface 101 and the second end surface 102, so that the flue gas can pass through the first through hole 100. Reduce the temperature of the flue gas when passing through. Optionally, the cooling element 10 can be formed by passing through a solid cooling element 10 to form the first through hole 100, or the cooling element 10 with the first through hole 100 can be injection molded through an injection molding process, or can also be formed by using a certain The material with the thickness is wound to form the cooling element 10 with the first through hole 100 .

Optionally, the material of the cooling element 10 includes silica gel, food grade materials and the like. The "food grade material" mentioned above refers to the toxic or harmful substances that can reduce or even not produce toxic or harmful substances to the human body or the environment when heated. Further optionally, the food-grade material includes, but is not limited to, one or more of white cardboard, kraft paper, and polylactic acid (PLA). Specifically, the cooling member 10 includes, but is not limited to, white cardboard of 50-200 g/㎡, kraft paper of 50-200 g/㎡, and the like.

Optionally, the length L1 of the cooling element 10 is 16-23 mm, and the outer diameter d1 is 6-6.6 mm. Wherein, the above-mentioned "length" refers to the dimension in the axial direction D1. In other words, the dimension of the cooling element 10 in its axial direction D1 is 16-23 mm. And the axial direction in the following text is represented by D1. The "outer diameter" mentioned above refers to a dimension in the radial direction D2. And the following radial direction is represented by D2. And because the cooling element 10 has a thickness, when the cooling element 10 is opened, the cooling element 10 has an outer peripheral side wall and an inner peripheral side wall. The outer peripheral sidewall has the exterior surface of the cooling element 10 , and the inner peripheral sidewall surrounds and forms the first through hole 100 . Therefore, the cooling element 10 has two dimensions in the radial direction, one is the size of the opposite sides of the outer peripheral side wall (ie, the outer diameter), and the other is the size of the opposite sides of the inner peripheral side wall (ie, the inner diameter). In other words, in the radial direction of the cooling element 10 , the dimensions of the opposite sides of the outer peripheral side wall are 6-6.6mm. And the same understanding can be made for the length, outer diameter, inner diameter, axial direction, and radial direction mentioned below in this application, and this application will not repeat them.

Designing the cooling element 10 in the above-mentioned size range can not only improve the cooling performance, but also ensure the concentration of the smoke and the suction resistance during smoking. If the outer diameter of the cooling tube is too small, the resistance of the exhaust gas will be too large, and if the outer diameter of the cooling tube is too large, the concentration of the flue gas in the cooling tube will be too small, affecting The taste of smoking smoke. Therefore, the outer diameter of the cooling tube is 6-6.6mm, which can make the concentration of the flue gas in the cooling element 10 full while ensuring low suction resistance. It should be noted that the suction resistance refers to the suction resistance. Wherein, the suction resistance refers to the resistance encountered when the smoke is sucked into the cooling tube and drawn out from the cooling element 10 .

The supporting part 20 mainly plays the role of carrying the subsequent functional part 30 . The carrier 20 is a structural part having a second through hole 200 . Specifically, the second through hole 200 can be formed through the opposite third end surface 201 and the fourth end surface 202 , so that the subsequent functional components 30 can be installed in the second through hole 200 . Optionally, the carrier 20 may be formed by a solid carrier 20 passing through to form the second through hole 200, or the carrier 20 with the second through hole 200 may be injection molded through an injection molding process, or may also be formed by using a The thick material is formed by winding to form the carrier 20 with the second through hole 200, or is prepared by extrusion. In addition, the bearing member 20 can be fixed in the first through hole 100 , that is, the bearing member 20 can remain fixed on the inner peripheral sidewall of the cooling member 10 . As for how to realize the fixing of the bearing member 20 , the present application will introduce in detail below.

Optionally, the material of the carrier 20 includes but 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 bearing member 20 is (0.7-0.8):1. In this embodiment, the outer diameter of the carrier 20 can be made smaller than the length of the carrier 20, so that the carrier 20 is cylindrical and slender, so that the carrier 20 can be sorted in the longitudinal direction by using the vibrating plate during automatic assembly. . When the ordering of the carriers 20 is wrong, for example, some of the carriers 20 are arranged in the outer diameter direction, the operator can find out and make corrections in time. If the ratio of the size of the outer diameter to the length is too large, such as 1:1, it is difficult for the operator to find out that a sorting error occurs. At this time, when assembling, the extension direction of the first through hole 100 and the second through hole 200 are perpendicular to each other. The flue gas cannot enter and discharge the cooling element 10, resulting in an error in the filling action and causing the equipment to stop working. If the size-to-length ratio of the outer diameter is too small, for example, 0.5:1, the outer diameter is too small, and the bearing part 20 cannot be fixed in the cooling part 10 during assembly.

Further optionally, the length L2 of the bearing member 20 is 6-8 mm, the outer diameter d2 is 5.8-6 mm, and the inner diameter d2' is 3-4 mm. The inner diameter of the bearing part 20 is the actual passage size of the smoke, so the inner diameter of 3-4mm can not only fix the functional part 30 well but also make the smoke pass smoothly, reducing the suction resistance. Moreover, the size of the inner and outer diameters also affects the size of the end surface of the carrier 20 , thereby affecting the performance of the carrier 20 against the filter 70 . In this embodiment, good abutting and fixing effects can be achieved through the above dimensions.

The functional part 30 is used to realize various functions. In other words, the shape, structure, material and other factors of the functional part 30 can be used to realize various functions. For example, if the material of the functional part 30 is a heat-absorbing material such as metal, plastic, etc., when the smoke is transmitted to the functional part 30, the heat-absorbing material can be used to absorb a large amount of heat, thereby further improving the cooling effect. If the functional part 30 has various spices, the functional part 30 can be used to change the taste of the smoke, thereby improving the enhancement, improving the quality of the smoke and the saturation, diversity and persistence of the taste. If the functional part 30 has various traditional Chinese medicine or western medicine ingredients, the functional part 30 can be used to make the smoke carry various traditional Chinese medicine or western medicine ingredients. Functions of health care and treatment.

In this embodiment, the functional part 30 is used as a flavoring part for schematic illustration, so as to change the taste of the smoke. Optionally, the functional part 30 includes a housing 31, and a liquid or gaseous functional part 32 disposed in the housing 31, the housing 31 abuts against the carrier 20; the housing 31 can be subjected to The rupture occurs when a preset external force is applied along the radial direction of the cooling element 10 . The functional part 30 includes a housing 31 and a functional part 32 disposed in the housing 31 , and the functional part 32 may be in liquid or gaseous state. The shell 31 abuts against the carrier 20 for fixing. And the shell 31 can be broken when receiving a preset external force along the radial direction of the cooling element 10 . For example, when the user pinches the cooling element 10 with his hand along the radial direction of the cooling element 10, when the extrusion force is greater than the preset external force, the outer shell 31 can be crushed, crushed, broken, or a hole 81 is broken to make it The inner functional part 32 is exposed. At this time, when the smoke passes through, the functional part 32 can be moved together, and the suction force of the user can also make the functional part 32 move, and finally suck it into the user's mouth. The application of the functional part 30 improves the taste and smell experience of the user. Further optionally, the functional part 30 may be molded by extrusion blow molding or the like.

Optionally, when the shell 31 is broken, the liquid functional part 32 can also be adsorbed onto the carrier 20, so that the user can more easily remove the functional part 32 when the smoke passes through and the user inhales during smoking. Inhaled into the oral cavity, the aroma can be released from the filter cotton more continuously, improving the user experience, and the liquid or gaseous functional part 32 can also be used to cool down the temperature to a certain extent.

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

Optionally, the shape of the functional part 30 may be spherical, ellipsoidal, or cylindrical. As shown in FIG. 4 , when the shape of the functional part 30 is spherical, the diameter d3 is 3-4 mm. As shown in FIG. 5 , when the shape of the functional part 30 is ellipsoidal or cylindrical, the diameter d3 in the radial direction of the cooling part 10 is 3-4 mm, and the length L3 in the axial direction of the cooling part 10 is 4-7 mm.

Through the detailed introduction to the various components of the cooling assembly 2, it can be found that the cooling assembly 2 provided in this embodiment can firstly increase the cooling function of the cooling element 10 by adding a functional element 30, or make the cooling element 10 have a cooling function in addition to the cooling function. Other functions, such as aroma enhancement, health care, treatment, etc., thereby improving the types of functions of the cooling component 2, and improving the user's taste and suction effect.

Secondly, by adding a carrier 20 and a functional part 30 in the first through hole 100 of the cooling part 10, and fixing the carrier 20 in the first through hole 100, the functional part 30 is fixed in the second through hole of the carrier 20 Within 200. In this way, the cooling element 10 can be used to fix the supporting element 20 , and the supporting element 20 fixes the functional element 30 so that the functional element 30 can be better fixed in the cooling element 10 and prevent the functional element 30 from moving in the cooling element 10 .

Again, in this embodiment, the third end surface 201 of the carrier 20 is flush with the first end surface 101, so that the third end surface 201 and the first end surface 101 can be used to abut against other components of the cartridge 1 such as the filter, In this way, other components can be better carried on the cooling element 10 and the bearing element 20 . And since the first end surface 101 and the third end surface 201 can be used to carry other components, there is no need to set the air-permeable sealing part 80 on the end surfaces, which can increase the ventilation area of the cooling assembly 2, make the smoke flow more smoothly, and reduce the suction resistance. In addition, since the air-permeable sealing part 80 is not required, raw materials can be saved, the difficulty of preparation can be reduced, and the cost can be reduced. Moreover, this embodiment makes full and reasonable use of the inner hole of the cooling component 2 to install and fix the explosive beads, without changing the original production equipment of the main body, and can reduce the cost of adjusting the equipment.

This application will introduce the relationship between the functional part 30 and the carrier part 20 . Please refer to FIG. 6 . FIG. 6 is a schematic structural diagram of a functional component and a bearing component in an embodiment of the present application. In this embodiment, the surface of the functional component 30 close to the third end surface 201 is flush with the third end surface 201 , or has a distance from the third end surface 201 .

Since the functional part 30 is fixed in the carrier part 20, the opposite ends of the functional part 30 in the radial direction can abut against the carrier part 20, and in the axial direction, the functional part 30 can be close to the third end surface 201 The surface of is flush with the third end surface 201 or has a distance therebetween. In other words, the side of the functional part 30 close to the third end surface 201 is located in the second through hole 200, and does not protrude from the carrier 20, so that after the functional part 30 is installed in the carrier 20, the When 20 is installed from the third end surface 201 of the cooling element 10 , the assembly equipment thereof will not touch the functional element 30 , avoiding damage to the functional element 30 and effectively protecting the functional element 30 . In this embodiment, the distance between the surface of the functional component 30 close to the third end surface 201 and the third end surface 201 is schematically described.

Please refer to FIG. 6 again. In this embodiment, the functional component 30 is positioned inside the carrier 20 in an orthographic projection on the carrier 20 .

In this embodiment, all the functional parts 30 are located in the carrier part 20, so that no matter which end of the carrier part 20 is loaded into the cooling part 10 during installation, no matter which end of the cooling part 10 is loaded into the assembly equipment All will collide with the functional part 30, further protecting the functional part 30.

Optionally, please refer to FIGS. 3-4 again. In this embodiment, in the axial direction of the carrier 20, the ratio of the dimension L2 of the carrier 20 to the dimension d3 of the functional part 30 is ( 1.5-2.5): 1, that is, the size of the supporting part 20 must be larger than that of the functional parts 30 so that the functional parts 30 are all arranged in the supporting part 20 . If the ratio of the size of the carrying part 20 to the size of the functional part 30 is too small, for example, less than 1.5:1, the carrying part 20 is too short and it is not easy to arrange all the functional parts 30 in the carrying part 20 . If the ratio of the size of the carrier 20 to the size of the functional part 30 is too large, such as greater than 2.5:1, the too long carrier 20 will reduce the effective cooling area of the cooling member 10, thereby reducing the cooling effect and reducing the temperature. The amount of smoke stored. In summary, the ratio of the size of the bearing part 20 to the size of the functional part 30 is (1.5-2.5):1.

Optionally, the center of the functional component 30 corresponds to the center of the bearing component 20 , the functional component 30 has the same distance between the third end surface 201 and the fourth end surface 202 , and the distance P is 1-2.5 mm.

Please refer to FIGS. 7-8 . FIG. 7 is a schematic structural diagram of a functional component and a bearing component in another embodiment of the present application. FIG. 8 is an exploded schematic diagram of a functional component and a bearing component in an embodiment of the present application. In this embodiment, the functional part 30 is interference-fitted with the carrier part 20, and the inner side wall of the carrier part 20 is provided with a first groove 21, and part of the functional part 30 is provided in the first groove 21. In the groove 21.

It can be seen from the above that the functional component 30 can be fixed in the second through hole 200 of the carrier 20 . This embodiment can be realized by making the functional part 30 interfere with the bearing part 20 . That is, in the radial direction of the cooling element 10, the size of the functional element 30 is larger than the inner diameter of the carrier element 20, so that when the functional element 30 enters the second through hole 200, the rebound force of the carrier element 20 can be used to tightly close the functional element 30. It abuts against the carrier 20 to be firmly fixed.

Optionally, please refer to FIGS. 3-4 again. In this embodiment, the bearing member 20 is in interference fit with the functional member 30, and the inner diameter d2' of the bearing member 20 and the functional member 30 are within The ratio of dimension d3 in the radial direction of the cooling element 10 is (0.9-0.95): 1, which ensures that the bearing element 20 and the functional element 30 maintain a certain amount of interference, and that the functional element 30 can be fixed within the above range. On the bearing part 20, the cooling part 10 will not be extruded and deformed, and the functional part 30 will not be damaged. If the inner diameter of the bearing part 20 and the size of the functional part 30 in the radial direction of the cooling part 10 are too small, such as less than 0.9:1, the bearing part 20 will not only be unable to be fixed on the cooling part 10, but also due to An inner diameter that is too small would damage the functional part 30 . Moreover, when the functional part 30 is broken, the inner diameter of the bearing part 20 becomes smaller due to the reverse extrusion force of the inner wall of the cooling part 10, which will increase the suction resistance. If the inner diameter of the bearing part 20 and the dimension of the functional part 30 in the radial direction of the cooling part 10 are too small, for example greater than 0.95:1. The bearing part 20 cannot be loaded into the cooling part 10, and the functional part 30 cannot be loaded into the bearing part 20 through interference fit.

In this embodiment, on the basis of interference fit, a first groove 21 is provided on the inner side wall of the carrier 20 , and some functional parts 30 are arranged in the first groove 21 . The first groove 21 can be used to relieve the extrusion force caused by the interference fit, so as to prevent the bearing member 20 from being squeezed and deformed, causing other components such as the pipe body 40 to be deformed as well, and finally causing problems of uneven shape, such as In the radial direction, the tubular body 40 is locally convex. In addition, the presence of the first groove 21 can further define the position of the functional component 30 in the carrier 20 , improving the accuracy of the position of the functional component 30 in the carrier 20 .

That is, the ratio of the length of the cooling element 10 to the length of the bearing element 20 is (1.7-2.4):1. If the ratio of the size of the cooling element 10 to the size of the carrier 20 is too small, such as less than 1.7:1, then the cooling element 10 is too short, and the cooling element 10 and the carrier 20 cannot reduce the temperature of the flue gas to an appropriate temperature. , the user may burn the mouth when inhaling. It can also be understood that if the carrier 20 is too long, when the carrier 20 is loaded into the cooling device 10, there will be a chance of error in the sequence of the equipment, resulting in a wrong loading action and the equipment will stop working.

If the ratio of the size of the cooling element 10 to the size of the bearing element 20 is too large, for example greater than 1.7:1, the cooling element 10 is too long. When the size of the pod 1 is constant, the size of other components such as the smoking part 60 will be reduced, thereby affecting the content of the smoking part 60, reducing the amount of stored smoke, affecting the taste of the puff, increasing the draw resistance, and reducing the user experience. Therefore, the above range of this embodiment can not only achieve good cooling performance, but also make other components have appropriate dimensions, and can also balance the relationship between the amount of smoke and the resistance to draw.

Please refer to FIG. 2-FIG. 3 again. In this embodiment, the cooling element 10 is in interference fit with the bearing element 20, and the inner diameter d1' of the cooling element 10 is the same as the outer diameter d2 of the bearing element 20. The ratio is (0.9-0.95):1.

In the axial direction, the cooling member 10 and the bearing member 20 can be fixed by an interference fit to ensure that the bearing member 20 and the cooling member 10 maintain a certain amount of interference, and within the above range It is ensured that the bearing part 20 is fixed on the cooling part 10, and the cooling part 10 will not be extruded and deformed outward. If the ratio of the inner diameter of the cooling element 10 to the outer diameter of the bearing element 20 is too small, for example, less than 0.9:1, the cooling element 10 cannot be fixed in the subsequent pipe body 40, and the functional element 30 will be damaged due to the small inner diameter. damage. Moreover, when the functional part 30 is broken, the inner diameter of the bearing part 20 becomes smaller due to the reverse extrusion force of the inner wall of the cooling part 10, which will increase the suction resistance. If the ratio of the inner diameter of the cooling element 10 to the outer diameter of the bearing element 20 is too small, for example greater than 0.95:1. Then the bearing part 20 cannot be loaded into the cooling part 10 through interference fit.

Of course, in other embodiments, the carrier 20 can also be bonded to the inner sidewall of the cooling element 10 by bonding, so that the carrier 20 is fixed on the cooling element 10 .
