The cooling element 10 is the main component of the pod 1 that performs the cooling function, and reduces the temperature of the smoke passing through the cooling element 10 to avoid scalding the user's mouth. The cooling element 10 has a structure with cooling holes 100 , specifically, the cooling holes 100 can be formed through two opposite sides, so that the temperature of the flue gas can be reduced when the flue gas passes through the cooling holes 100 . Optionally, the cooling member 10 can be formed by passing through a solid cooling member 10 to form the cooling hole 100, or the cooling member 10 with the cooling hole 100 can be injected through an injection molding process, or can also be passed through using a material with a certain thickness.

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 front and back of this application is represented by D1. The "outer diameter" mentioned above refers to a dimension in the radial direction D2. And the radial direction in the front and back of this application 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 side wall has the exterior surface of the cooling element 10 , and the inner peripheral side wall is surrounded by a cooling 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 6-6.6 mm. 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 functional component 2 includes a bearing part 20 and a functional part 30 , and the bearing part 20 mainly plays a role of carrying the subsequent functional part 30 . The carrier 20 is a structural part having a through hole 200 . Specifically, the through hole 200 can be formed through two opposite ends, so that the subsequent functional component 30 can be installed in the through hole 200 . Optionally, the carrier 20 can be formed by passing through a solid carrier 20 to form the through hole 200, or the carrier 20 with the through hole 200 can be injection molded through an injection molding process, or can also be made by using a material with a certain thickness. The carrier 20 is wound to form a through-hole 200 , or prepared by extrusion. In addition, the bearing member 20 can be fixed in the cooling 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 outer diameter to the length is too large, for example, 1:1, it will be difficult for the operator to find out that the sequence error occurs. At this time, when assembling, the cooling hole 100 is perpendicular to the extending direction of the through hole 200, and the smoke cannot enter And discharge carrier 20, cause filling action error and cause 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 carrier 20 cannot be fixed in the tube body 40 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.

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. When the shape of the functional part 30 is spherical, the diameter d3 is 3-4mm. 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.

Further optionally, when the filter element 70 or the carrier element 20 is made of polylactic acid, pultrusion molding can be used. Optionally, in the axial direction of the tube body 40, the length L5 of the filter element 70 is 1-10 mm. In the radial direction of the tube body 40, the diameter d5 of the filter element 70 is 6.5-7 mm.

Optionally, when the pipe body 40 and the cooling element 10 are coiled, flat or oblique coils can be used. The pipe body 40 and the cooling element 10 can be wound in the same way or in different ways. If it is a flat roll, it can be made of food-grade paper with a single thickness ranging from 50-200g, and 4-5 layers are stacked together, and only glue with a width of 1mm to 2mm is applied to the joint of the last layer to fix it, which can reduce winding. difficulty. If it is obliquely rolled, 3 layers of food-grade paper can be used, and the thickness ratio from one side to the other is 8:10:6, and they are rolled together in a spiral form at an angle of 135°±15. And glue is applied between the layers, so the three layers can be firmly bonded to each other. After leaving the core, the obliquely rolled paper tube has good stability, strength and roundness.

The pod 1 provided in this embodiment can firstly increase the cooling function of the cooling component 10 by adding the functional component 30, or enable the cooling component 10 to have other functions besides the cooling function, such as increasing fragrance, health care, treatment, etc. Thereby, the types of functions of the pod 1 are improved, and the user's taste and smoking effect are improved.

Secondly, the carrier 20 is arranged in the receiving hole 41, and the functional part 30 abuts in the through hole 200 of the carrier 20, so that the carrier 20 can be used to install the functional part 30 to limit the position of the functional part 30, preventing The functional part 30 moves freely.

Moreover, disposing the functional component 2 between the cooling element 10 and the filter element 70 may not affect the normal use of the cooling element 10 . In addition, the functional component 2 is arranged between the cooling element 10 and the filter element 70, so that the functional element 30 can be closer to the filter element 70. When the pod 1 is in use, especially when used with a smoking device, it is usually necessary to insert the smoking element 60 In the smoking appliance, making the functional part 30 close to the filter 70 can facilitate the user to use the functional part 30, so as to prevent the user from being unable to use the functional part 30 when the functional part 30 is in the smoking appliance.
