When used, the generated smoke is cooled by the cooling design. On the one hand, it can prevent the excessively high temperature smoke from burning the user's mouth, and on the other hand, it can reduce the production of harmful substances, which is healthier and more environmentally friendly.

[0003] The existing cooling designs are mostly cylindrical structures, including an outer wrapping layer and a cooling structure filled inside. The commonly used cooling structures are generally multiple fiber bundles arranged side by side. Although these cooling structures can achieve a certain cooling effect, they all have the following defects:

[0004] Only axial cooling is considered, so the cooling channels are set along the axial direction of the outer wrapping layer. Although it is close to the direction of smoke travel, the cooling channels in other directions are abandoned, resulting in a weaker cooling effect.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of this patent application, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to ordinary technicians in this field.

[0007] To achieve the above objectives, the technical solution of the present invention is: a multi-directional smoke cooling element, comprising an outer wrapping tube and an inner filling body arranged inside the outer wrapping tube, wherein the outer wrapping tube is a hollow cylindrical structure;

[0011] The filaments are made of PLA.

[0012] The filaments include warp threads and weft threads, the warp threads and weft threads are both in multiple numbers, and the warp threads and weft threads are interwoven with each other to form ventilation holes.

[0013] The filaments further include a dense tuning line, and the number of the dense tuning line is at least one; the extension direction of the dense tuning line is radial or latitudinal or both radial and latitudinal;

[0014] The ventilation holes include basic holes and fine-tuning holes. The warp threads and weft threads are interwoven to form basic holes. The fine-tuning threads are interwoven with the warp threads and weft threads to form fine-tuning holes.

[0015] The starting network, intermediate network and terminal network include any one or any combination of the following layout structures;

[0016] Single-thread structure: There is only one dense-tweed thread, which is set beside a single weft thread and parallel to the single weft thread;

[0017] Double-root structure: There are two closely-adjusted threads, which are arranged on both sides of a single weft thread and are parallel to the single weft thread.

[0018] Poly-even structure: The number of closely-adjusted threads is an even number greater than two, and the same number is arranged on both sides of a single weft thread and is parallel to the single weft thread.

[0019] The starting net, the middle net and the terminal net all include a single net layer or two single net layers or multiple single net layers; the single net layer is woven from filaments and through holes are woven to form ventilation holes.

[0020] The single mesh layer is provided with grooves, and the arrangement structure of the grooves is any one or any combination of the following:

[0022] The oblique Z structure is formed by connecting a single upper convex structure and a single lower convex structure up and down.

[0023] The outer wrapping tube is made of a material that includes heat-absorbing and temperature-reducing materials.

[0024] The outer wrapping tube is made of any one of non-woven fabric, mesh fabric or non-porous film; the materials used to make the non-woven fabric, mesh fabric and non-porous film all include heat-absorbing and cooling materials.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. A multi-directional smoke cooling element of the present invention includes an outer wrapping tube and an inner filling body arranged inside the outer wrapping tube, wherein the inner filling body includes a starting net, an intermediate net, and a terminal net connected as one, the number of the starting net and the terminal net are both one, and the number of the intermediate net is at least one (preferably multiple), and as far as the internal connection of the starting net, the intermediate net, and the terminal net is concerned, they are adjacent to each other and connected one by one, that is, there is only one intermediate net adjacent to and connected to the starting net, and there is only one intermediate net adjacent to and connected to the terminal net. This connection relationship enables multiple axial flues (i.e., cooling channels) to exist inside the inner filling body and between the inner filling body and the inner wall of the outer wrapping tube to achieve axial cooling. On this basis, the starting net, the intermediate net, and the terminal net are respectively provided with multiple vents, which can provide cooling channels in other directions, especially cooling in a direction perpendicular to the axial direction, thereby achieving the combination of cooling channels in multiple directions and improving the cooling effect. Therefore, the present invention can achieve multi-directional cooling and has a strong cooling effect.

[0027] 2. In a multi-directional smoke cooling element of the present invention, the shapes of the starting net, the middle net, and the terminal net are any one or any combination of the following structures: plane shape, arc shape, or twisted shape. When applied, this design can not only enrich the structure of the axial cooling channel, extend the retention time of smoke in the channel, and improve the cooling effect, but also enrich the ventilation direction of the vents, thereby enriching the non-axial cooling direction and further improving the cooling effect. Therefore, the present invention can enrich the cooling direction and enhance the cooling effect.

[0028] 3. In a multi-directional smoke cooling element of the present invention, the materials (i.e., filaments) used to make the starting net, the middle net, and the terminal net are all heat-absorbing and cooling materials, preferably PLA (i.e., polylactic acid). This material not only produces a heat-absorbing effect to reduce the temperature of the smoke, but also shrinks when heated, reducing its occupied space. This morphological change complements the multi-directional cooling channel, especially making the cooling channels involved in the vents more diversified, and making full use of all spaces for cooling. In addition, the shrinking and deformed polylactic acid will reduce the occupied space of each structural monomer (such as the starting net, the middle net, and the terminal net), widen the space through which the smoke can flow in the outer wrapping tube, avoid blockage, and ensure the smooth flow of smoke. Therefore, the present invention not only has a strong cooling effect, but also ensures the smooth flow of smoke.

[0029] 4. In a multi-directional flue gas cooling element of the present invention, the filament includes warp, weft and close-adjusting wires, and the number of the close-adjusting wires is at least one; the extension direction of the close-adjusting wires is radial or weft or both radial and weft; the ventilation holes include basic holes and close-adjusting holes, the warp and weft are interwoven to form basic holes, and the close-adjusting wires are interwoven with the warp and weft to form close-adjusting holes. When used, the close-adjusting holes and the basic holes can not only ventilate at the same time to construct cooling channels in other directions, but also can utilize the technical limitations of the different areas of the close-adjusting holes and the basic holes. Preferably, the area of ​​the close-adjusting holes is smaller than the basic holes, so that the starting net, the middle net, and the terminal net all have different gap distribution densities, which is convenient for adjusting the multi-directional cooling channels, enriching the application effect, and adapting to more application occasions. On this basis, the folding or extrusion operation when obtaining the inner filling body and the optimization of the number of close-adjusting wires can further increase the adjustability.

[0030] 5. In a multi-directional flue gas cooling element of the present invention, the starting net, the middle net, and the terminal net include any one or any combination of the following layout structures: single-root structure, double-root structure, and multi-pair structure. In specific applications, the types and quantities of single-root structure, double-root structure, and multi-pair structure can be selected to obtain various gap distribution results, thereby obtaining richer cooling channels and achieving more combined cooling effects. On this basis, the diameters of the warp, weft, and close-adjusting wires are adjusted to further improve adjustability. Therefore, the present invention has strong adjustability and rich cooling methods.

[0031] 6. In a multi-directional smoke cooling element of the present invention, the starting net, the middle net, and the terminal net can all be single-layer structures, or double-layer structures, or multi-layer structures. When it is a single-layer structure, it only includes one single-net layer, when it is a double-layer structure, it only includes two single-net layers, and when it is a multi-layer structure, it includes multiple single-net layers. However, no matter how many layers there are, the single-net layer is provided with multiple vents. This design can not only enrich the design range of the cooling channel, but also optimize the support of the inner filling body to the outer wrapping tube, and improve the firmness of the combination of the two. Therefore, the present invention not only has a better cooling effect, but also has a stronger firmness.

[0032] 7. In a multi-directional smoke cooling element of the present invention, when the outer wrapping tube is made of a material that includes heat-absorbing and cooling materials, the outer wrapping tube can also cool the smoke, especially when the outer wrapping tube is made of any one of non-woven fabrics, mesh fabrics or non-porous films, and the materials of the non-woven fabrics, mesh fabrics and non-porous films all include heat-absorbing and cooling materials, the pores of the non-woven fabrics or mesh fabrics can further enhance the cooling effect. Therefore, the cooling effect of the present invention is relatively strong. BRIEF DESCRIPTION OF THE DRAWINGS
