[0042] The manufacturing process for existing aroma generating elements is cumbersome, making it inconvenient for users to prepare them themselves. Users must purchase pre-made aroma generating elements. Furthermore, most aroma generating technologies involve open flames, posing safety risks. Flameless aroma generating technologies, lacking a combustion process, result in a missing aroma product, resulting in an unrealistic flavor.

Specifically, after the aroma generating element 200 is placed in the aroma generating device, the heated air is flowed through the air flow channel 210 of the aroma generating element 200, so that the aroma components in the aroma-forming tissue of the aromatic plant are volatilized, thereby obtaining aromatic gas or smoke; based on the manufacturing method and mold of the aroma generating element provided in this application, users can make the aroma generating element by themselves according to their own needs, without having to purchase the finished product of the aroma generating element, which also reduces costs.

[0044] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0045] Figure 2 This is a flow chart of a method for manufacturing a fragrance generating element provided in an embodiment of the present application. This embodiment provides a method for manufacturing a fragrance generating element, and the specific steps of the method for manufacturing a fragrance generating element are as follows:

[0046] S201, drying the aroma-forming tissue of the aromatic plant and grinding it into powder;

[0047] S202, mixing the powder with the binder, adding a solvent, and stirring to form a paste-like mixture;

[0048] S203, placing the pasty mixture in a mold for making an aroma generating element, and extruding the pasty mixture to form a preform of the aroma generating element, wherein a preset number of columnar cores are arranged in parallel in the mold for making the aroma generating element;

[0049] S204 , taking out the preform of the aroma generating element from the mold for manufacturing the aroma generating element, and drying the preform of the aroma generating element until the adhesive is solidified to obtain the aroma generating element with an airflow channel.

[0050] In this embodiment, aromatic plants such as lavender, tea, coffee, tobacco, fennel, pepper, cumin and tangerine peel, such as roots, stems, leaves, flowers and fruits, are dried and then ground into powder. In this embodiment, the drying method and the grinding method are not limited, and the particle size of the powder is not limited.

[0051] The powder is mixed with a binder to shape the powder. Optionally, the binder may include, but is not limited to, one or more of cellulose, starch, resin, protein, and inorganic salts. The powder and binder are mixed and a solvent is added, followed by stirring to form a paste-like mixture. The solvent may include, but is not limited to, water or ethanol. It should be noted that the ratio of the powder, binder, and solvent is not limited in this embodiment; as long as a paste can be formed and subsequently solidified after drying, the mixture will be sufficient.

[0052] For the paste mixture, in order to prepare it as Figure 1 The aroma generating element shown includes an air flow channel, and the prepared aroma generating element has a stable shape, is not easily deformed, and has a uniform texture. The paste mixture can be placed in a mold for making the aroma generating element, and the paste mixture is extruded to form a preform of the aroma generating element, wherein a preset number of columnar cores are arranged in parallel in the mold for making the aroma generating element, and the columnar cores are used to form the air flow channel. It should be noted that the mold for making the aroma generating element can be a mold of any structure, as long as it can form Figure 1 The fragrance generating element shown includes an air flow channel, which is not limited in this embodiment.

[0053] Finally, the aroma generating element preform is removed from the aroma generating element mold. After removal, the aroma generating element preform is dried until the adhesive solidifies, thereby obtaining an aroma generating element having airflow channels. The drying method and time are not limited in this embodiment, as long as the adhesive solidifies.

[0054] The method for making an aroma generating element provided in this embodiment comprises the following steps: drying the aroma-forming tissue of an aromatic plant and grinding it into a powder; mixing the powder with a binder, adding a solvent, and stirring to form a paste mixture; placing the paste mixture in a mold for making the aroma generating element, and extruding the paste mixture to form a preform of the aroma generating element, wherein a preset number of columnar cores are arranged in parallel in the mold for making the aroma generating element; taking out the preform of the aroma generating element from the mold for making the aroma generating element, and drying the preform of the aroma generating element until the binder solidifies to obtain an aroma generating element with an airflow channel. This embodiment is based on a paste mixture formed by powder of the aroma-forming tissue of an aromatic plant, a binder, and a solvent. The aroma generating element including an airflow channel can be prepared conveniently and efficiently by using a mold, and the prepared aroma generating element has a stable shape, is not easily deformed, and has a uniform texture, so that users can make the aroma generating element by themselves according to their own needs, without having to purchase finished aroma generating elements, which also reduces costs.

[0055] Based on any of the above embodiments, Figure 3 As shown, this embodiment provides a mold 100 for making an aroma generating element, which can be applied to the above-mentioned method for making an aroma generating element to make the following: Figure 1 The aroma generating element 200 is shown having an air flow channel 210.

[0056] See also Figure 3 , and the schematic diagram of the assembly process of the mold for the fragrance generating element Figure 4a 、 4b , 4c, 4d, 4e, 4f, the production mold 100 of the fragrance generating element may specifically include: a left mold body 110, a right mold body 120, a top extrusion piece 140, a bottom support piece 130 and a mold base 150.

[0057] The left mold body 110 and the right mold body 120 are arranged opposite to each other to form a vertically penetrating cavity 160 . The vertically penetrating cavity 160 is mainly used to form the side wall of the fragrance generating element 200 .

[0058] The bottom support member 130 includes a bottom plate 131 and a first step surface 132 protruding from the bottom plate 131. A preset number of first through holes 133 perpendicular to the first step surface 132 are provided on the bottom support member 130. The first step surface 132 can be inserted into the cavity 160 from the lower end of the cavity 160 and engaged with the cavity 160, wherein the first step surface 132 is used to form the bottom surface of the fragrance generating element 200.

[0059] A preset number of columnar cores 151 are vertically disposed on the top surface of the mold base 150 . The columnar cores 151 are used to pass through the first through hole 133 and extend into the mold cavity 160 to form the air flow channel 210 of the fragrance generating element 200 .

[0060] The top extrusion piece 140 includes a top plate 141 and a second step surface 142 protruding from the top plate 141. A preset number of second through holes 143 perpendicular to the second step surface 142 are provided on the top extrusion piece 140. The second step surface 142 can be inserted into the cavity 160 from the upper end of the cavity 160 and engaged with the cavity 160, and the cylindrical core 151 is inserted into the second through hole 143 for extruding the fragrance generating element 200 from the upper end of the cavity 160, wherein the second step surface 142 is used to form the top surface of the fragrance generating element 200.

[0061] The left mold body 110, the right mold body 120, the top extrusion piece 140, the bottom support piece 130 and the mold base 150 of the mold 100 for making the fragrance generating element are all detachable parts. Figure 4a 、 4b 4c, 4d, 4e, and 4f are schematic diagrams of the assembly process of the mold for the fragrance generating element. Specifically, Figure 4a , the left mold body 110 and the right mold body 120 can be spliced together to form a vertically through-going cavity 160; Figure 4b , insert the first step surface 132 of the bottom support member 130 into the cavity 160 from the lower end of the cavity 160 to form a Figure 4c structure; such as Figure 4d , the columnar core 151 on the top surface of the mold base 150 is extended into the mold cavity 160 through the first through hole 133 of the bottom support member 130 to form a Figure 4e structure; such as Figure 4f Insert the second step surface 142 of the top extrusion piece 140 into the cavity 160 from the upper end of the cavity 160, and insert the cylindrical core 151 into the second through hole 143 of the top extrusion piece 140, that is, assemble as shown below. Figure 3The structure of the mold 100 for making the fragrance generating element after assembly is shown, thus forming a closed mold space with a cylindrical core 151 inside, which can be used to prepare the fragrance generating element 200. It should be noted that during the assembly process, the top extrusion piece 140 is installed last, that is, the left mold body 110, the right mold body 120, the bottom support piece 130 and the mold base 150 are assembled first to form a mold space with an open top end, the raw materials of the fragrance generating element 200 are added to the mold space from the top end, and then the top extrusion piece 140 is installed, and pressure is applied to the top extrusion piece 140 to extrude and form the fragrance generating element 200.

[0062] It should be noted that the shape of the cavity 160 depends on the shape of the side wall of the aroma generating element 200. If the aroma generating element 200 is cylindrical, the cavity 160 is a cylindrical cavity 160. For example, Figure 1 The fragrance generating element 200 shown is cylindrical, and the cavity 160 is a cylindrical cavity 160. The cavity 160 is formed by the left mold body 110 and the right mold body 120 docking to facilitate the separation from the side wall of the fragrance generating element 200 when the fragrance generating element 200 is demoulded.

[0063] In this embodiment, the first through holes 133, the second through holes 143 and the cylindrical core 151 have the same number and the same direction (all are arranged along the axial direction of the cavity 160 in the assembled state), and their positions correspond to each other to facilitate the coordination of the first through holes 133, the second through holes 143 and the cylindrical core 151.

[0064] It should be noted that a cylindrical core 151 is provided on the top surface of the mold base 150, and a first through hole 133 is provided on the bottom support member 130 so that when the fragrance generating element 200 is demoulded, the fragrance generating element 200 can be supported by the bottom support member 130, thereby facilitating the extraction of the cylindrical core 151 from the fragrance generating element 200 and avoiding deformation of the fragrance generating element 200.

[0065] The second through hole 143 is provided on the top extrusion piece 140 so that the cylindrical core 151 can pass through the second through hole 143 when the second step surface 142 of the top extrusion piece 140 is inserted into the cavity 160 from the upper end of the cavity 160, thereby increasing the stroke of the second step surface 142 in the cavity 160 to better extrude the internal fragrance generating element 200. If the second through hole 143 is not provided, the second step surface 142 will not be able to continue to move after it moves to abut against the cylindrical core 151, that is, it will not be able to continue to extrude the fragrance generating element 200. Therefore, the length of the columnar core 151 provided on the top surface of the mold base 150 should be greater than the sum of the height of the bottom support member 130 and the height of the aroma generating element 200, the height of the cavity 160 should be greater than the sum of the height of the first step surface 132 of the bottom support member 130 and the height of the aroma generating element 200, and the height of the cavity 160 should be less than or equal to the sum of the height of the first step surface 132 of the bottom support member 130, the height of the second step surface 142 of the top extrusion member 140, and the height of the aroma generating element 200. Preferably, the height of the cavity 160 is equal to the sum of the height of the first step surface 132 of the bottom support member 130, the height of the second step surface 142 of the top extrusion member 140, and the height of the aroma generating element 200, so as to ensure that the height of the aroma generating element 200 produced each time remains consistent.

[0066] Optionally, the number of second through holes 143 may be greater than the number of cylindrical cores 151. In this way, when the second step surface 142 of the top extrusion piece 140 is inserted into the mold cavity 160 from the upper end thereof, some of the second through holes 143 are not inserted with the cylindrical cores 151. In the event that an excessive amount of raw material of the fragrance generating element 200 is added, some of the excess raw material of the fragrance generating element 200 can be discharged through these second through holes 143 during the extrusion process. It should be noted that the number of first through holes 133 needs to be the same as the number of cylindrical cores 151 to ensure the sealing of the bottom of the mold space and prevent the raw material of the fragrance generating element 200 from leaking from the bottom during the addition process.

[0067] In this embodiment, the first step surface 132 of the bottom support member 130 and the second step surface 142 of the top extrusion member 140 are planes, which are respectively used to form the bottom surface and top surface of the fragrance generating element 200; of course, if the bottom surface and top surface of the fragrance generating element 200 are not planes, for example, the bottom surface and / or top surface of the fragrance generating element 200 are hemispherical, then the first step surface 132 of the bottom support member 130 and the second step surface 142 of the top extrusion member 140 also need to be adapted to the shape of the bottom surface and top surface of the fragrance generating element 200.

[0068] Based on any of the above embodiments, the mold 100 for manufacturing the aroma generating element may further include a locking structure for securing the left mold body 110 and the right mold body 120 together when the left mold body 110 and the right mold body 120 are assembled, thereby forming a stable mold cavity 160. This prevents the left mold body 110 and the right mold body 120 from separating from each other during extrusion molding of the aroma generating element 200. The locking structure may be any structure, such as a buckle, a clamp, etc., and is not limited in this embodiment.

[0069] Based on the mold 100 for manufacturing the fragrance generating element provided in the above embodiment, the fragrance generating element 200 including the air flow channel 210 can be manufactured more conveniently and efficiently, which facilitates the extrusion molding of the fragrance generating element 200, makes the fragrance generating element 200 have a uniform texture, and also facilitates the demolding of the fragrance generating element 200.

[0070] In the above embodiment, before placing the paste mixture in the mold for making the fragrance generating element and extruding the paste mixture to form the preform of the fragrance generating element, the mold for making the fragrance generating element may be assembled first.

[0071] Optionally, the left mold body 110, the right mold body 120, the bottom support member 130 and the mold base 150 of the mold 100 for making the fragrance generating element can be assembled to form a cavity 160 with an open upper end, wherein the left mold body 110 and the right mold body 120 can be spliced to form a cavity 160 that passes through from top to bottom, the first step surface 132 of the bottom support member 130 is inserted into the cavity 160 from the lower end of the cavity 160, and the columnar core 151 on the top surface of the mold base 150 passes through the first through hole 133 of the bottom support member 130 and extends into the cavity 160, thereby forming a cavity 160 with an open upper end.

[0072] Furthermore, the paste mixture can be added into the mold cavity 160 from the upper end of the mold cavity 160, and the second step surface 142 of the top extrusion piece 140 can be inserted into the mold cavity 160 from the upper end of the mold cavity 160, so that the cylindrical core 151 is inserted into the second through hole 143, and the paste mixture is extruded and molded by the top extrusion piece 140 to form a preform of the fragrance generating element 200.

[0073] On the basis of the above embodiment, when taking out the preform of the fragrance generating element from the mold for making the fragrance generating element, the mold for making the fragrance generating element can be disassembled to facilitate demoulding of the preform of the fragrance generating element.

[0074] Optionally, the mold 100 for making the fragrance generating element is disassembled to remove the prefabricated fragrance generating element 200. Specifically, the disassembly can be performed in the following order:

[0075] Remove the top extrusion 140 from the upper end of the cavity 160;

[0076] Separating the mold base 150 to extract the cylindrical core 151 from the interior of the preform of the fragrance generating element 200;

[0077] Separating the left mold body 110 and the right mold body 120 to separate the left mold body 110 and the right mold body 120 from the side wall of the preform of the fragrance generating element 200;

[0078] The preform of the aroma generating element 200 is removed from the bottom support member 130 .

[0079] Through the above disassembly process, first removing the top extrusion member 140 and the mold base 150 ensures that the cylindrical core 151 can be smoothly extracted from the interior of the preform of the fragrance generating element 200, and the air flow channel 210 is intact and not deformed; then separating the left mold body 110 and the right mold body 120 ensures that the side walls of the preform of the fragrance generating element 200 are intact and not deformed. Of course, in this embodiment, the order of removing the top extrusion member 140 and the mold base 150 is not limited, as long as they are removed before separating the left mold body 110 and the right mold body 120. In addition, the bottom support member 130 can also be separated before separating the left mold body 110 and the right mold body 120, but it needs to be separated after separating the mold base 150.

[0080] Based on the above embodiment, after the preform of the aroma generating element 200 is dried until the adhesive is cured, a housing can be further provided on the outside of the preform of the aroma generating element 200 to protect the aroma generating element 200 from damage or to enhance heat conduction. The housing at least covers the side surfaces of the aroma generating element 200. Optionally, the housing can be of any structure or material, for example, it can be coated with a structural reinforcement material or a heat conducting material, such as aluminum foil.

[0081] Optionally, after the preform of the aroma generating element 200 is dried until the adhesive is cured, a filter structure may be provided at both ends of the air flow channel 210 of the preform of the aroma generating element 200 to prevent powder from falling out when heated air flows through the air flow channel 210 and contaminating the user and the device. The filter structure may be of any structure or material, such as a stainless steel mesh or a filter layer made of cellulose acetate.

[0082] As an example, when a shell is provided outside the preform of the fragrance generating element 200 and filter structures are provided at both ends of the air flow channel 210, the specific method can be as follows: Figure 5 As shown, the housing 220 can fix the filter structure 230 at both ends of the air flow channel 210 , and the housing 220 does not cover the filter structure 230 .

[0083] Optionally, the filter structure 230 may be a porous structure. Optionally, an extraction solvent and / or additional aromatic substances may be added to the filter structure 230. The extraction solvent, such as propylene glycol, may facilitate the extraction of aromatic components from the aroma generating element 200. The additional aromatic substances may be essences, spices, etc., which may increase the variety of aromas in the ultimately formed aromatic gas or smoke.

[0084] Based on the manufacturing method of the fragrance generating element provided in the above embodiment, the fragrance generating element 200 including the air flow channel 210 can be manufactured more conveniently and efficiently, which facilitates the extrusion molding of the fragrance generating element 200, makes the fragrance generating element 200 have a uniform texture, and also facilitates the demolding of the fragrance generating element 200.
