Description

[Technical Field]

[0001] The present invention relates to the field of atomization, and more particularly to an aerosol formation unit, an atomization module, a manufacturing process and a heater. [Background technology]

[0002] A new atomization method, low-temperature non-combustion and heating, has been gaining popularity in recent years both domestically and internationally because it significantly reduces the generation of harmful substances compared to conventional combustion atomization. However, most non-combustion and heating atomization devices currently on the market are similar, combining the heater and atomization device, while using disposable stick-shaped atomization media. However, several issues still remain during use. For example, with the insertion-type heating method, carbonized dirt easily accumulates on the heating tip, the heating tip is easily broken, and it is difficult to clean.

[0003] Furthermore, in the case of a method in which the stick-shaped atomization medium is heated externally, the contact between the heating element and the stick-shaped atomization medium is poor, resulting in uneven heating. Another problem that exists in most of these methods is that the contact surface between the heating element and the stick-shaped atomization medium is small, which slows the rate at which heat is transferred from the heating element to the stick-shaped atomization medium. Furthermore, areas close to the heating element burn, while areas farther from the heating element remain unheated, resulting in low utilization and long waiting times for users. Therefore, improvements are needed to address these issues. Summary of the Invention [Problem to be solved by the invention]

[0052] In order to make the technical features, objects and effects of the present invention more clearly understood, specific embodiments of the present invention will be described in detail with reference to the drawings.

[0053] 1 to 3, an aerosol forming unit 10 in a preferred embodiment of the present invention includes an atomization unit 11 formed by winding an atomization module 11a, a filter 12 provided at one end of the atomization unit 11, a filter tip 13 provided at one end of the atomization unit 11 spaced apart from the filter 12, and a support tube 14 covering the outside of the atomization unit 11 and the filter 12. The filter 12 mainly comes into contact with the human body to filter out foreign matter and large particles, and also lowers the temperature of the vapor entering the mouth to an appropriate level. The role of the filter tip 13 is to prevent the entry of large particles such as dust and to prevent the leakage of tobacco shreds, tobacco leaves, etc. from within the aerosol forming unit 10.

[0054] 4, the support tube 14 can connect the atomization unit 11 and the filter 12. Preferably, the support tube 14 is a wound support paper. The support paper provides a certain degree of hardness to the aerosol formation unit 10, allowing the aerosol formation unit 10 to be smoothly inserted into the heater 20. Furthermore, the support tube 14 can support the atomization unit 11 and position the electrode 113 of the atomization unit 11, ensuring good contact between the elastic contact point 211 of the heater 20 and the electrode 113 of the aerosol formation unit 10.

[0055] 5 and 6, the atomization module 11a includes a solid aerosol-forming substrate 111, a heater 112, and an electrode 113. The solid aerosol-forming substrate 111 is in the form of a flexible sheet, and preferably, fibers extracted from a herbaceous plant may be used to form the flexible, foldable paper- or sheet-like solid aerosol-forming substrate 111. Then, as shown in FIGS. 7 and 8, by rolling or folding this, the atomization unit 11 having a specific shape such as a rod or block is formed, and by combining it with a filter 12 or the like, the rod- or block-shaped aerosol-forming unit 10 can be inserted into the heater 20.

[0056] The electrode 113 of the atomization unit 11 is exposed to the outside. Therefore, after the aerosol formation unit 10 is inserted into the heater 20, the electrode 113 comes into contact with a contact point in the heater 20 to become conductive, thereby supplying electricity to the atomization unit 11 to perform atomization by heating. Of course, as can be understood, the atomization module 11a can be folded to form the atomization unit 11, or the atomization unit 11 can be formed by a combination of rolling and folding at the same time.

[0057] The heating element 112 includes a flexible first wire 1121 sewn to the solid aerosol-forming substrate 111. The first wire 1121 is made of a conductive material and is fixed to the sheet-like solid aerosol-forming substrate 111 by being sewn. The electrode 113 includes two conductive electrodes 1131 electrically connected to the first wire 1121, respectively. The conductive electrodes 1131 become conductive when they come into contact with contact points of the heater 20. As a result, electricity is supplied from the heater 20 to the heating element 112, which heats the solid aerosol-forming substrate 111 and forms an aerosol.

[0058] 5 and 6 , in some embodiments, the first wire 1121 includes a stitching portion 1122 that penetrates from a first side A to a second side B opposite the first side A and then returns to the first side A. The stitching portion 1122 allows the first wire 1121 to be sewn to the solid aerosol-forming substrate 111, thereby better adhering the first wire 1121 to the solid aerosol-forming substrate 111, making the bond more stable and less likely to come loose. Depending on the stitching length of the first wire 1121, one or more stitching portions 1122 may be provided along the wiring direction during sewing, allowing the first wire 1121 to be sewn to the solid aerosol-forming substrate 111.

[0059] As can be seen, in some embodiments, the sewn portion 1122 may include a first section 1122a and a second section 1122b that are connected in sequence. The first section 1122a and the second section 1122b are located in the same sewing hole. That is, the sewn portion 1122 is inserted into the solid aerosol-forming substrate 111 from the first side A toward the second side B, and then returns to the first side A through the original sewing hole. By embedding the sewn portion 1122 in the solid aerosol-forming substrate 111, the solid aerosol-forming substrate 111 can be heated.

[0060] Typically, the first wire 1121 is sewn along a predetermined path to form the heating element 112, and has several sewn portions 1122. This ensures a stable connection with the solid aerosol-forming substrate 111 and also ensures a sufficient heating range. Furthermore, the first wire 1121 is located on the first side A and includes connecting sections 1123 that connect two adjacent sewn portions 1122. This allows the length of the heating element 112 distributed along the first side A to be longer, thereby increasing the heating range. Of course, only one sewn portion 1122 may be provided. Both ends of the heating element 112 are fixed to the solid aerosol-forming substrate 111 by electrodes 113.

[0061] Forming the heater 112 by sewing a wire is advantageous for using a thinner heating wire. This allows for a smaller cross-sectional area, which results in a faster heating start speed and faster heat dissipation. It also allows the solid aerosol-forming substrate 111 to be driven with lower power, which is advantageous for energy conservation. Furthermore, forming the heater 112 by sewing a wire is advantageous for mass production. Furthermore, the production process for filamentous wire generally involves wire drawing using a die hole, which allows for accurate size control, making the electrical resistance of the heater 112 more stable.

[0062] The wire diameter is usually thin, typically a round wire with a cross-sectional diameter of 0.2 mm. Heating element 112 formed by sewing the wire to solid aerosol-forming substrate 111 and solid aerosol-forming substrate 111 form an integrated structure. By fixing heating element 112 to solid aerosol-forming substrate 111, solid aerosol-forming substrate 111 can serve as a carrier for heating element 112. This can prevent deformation of heating element 112 formed from wire, ensure good adhesion between heating element 112 and solid aerosol-forming substrate 111, and further facilitate mass automatic production.

[0063] Possible materials for the first wire 1121 include metallic materials such as nickel-based alloys, stainless steel-based alloys, chromium-containing alloys, titanium-containing alloys, tungsten-containing alloys, molybdenum-containing alloys, iron-containing alloys, and tin-containing alloys, as well as non-metallic conductive materials such as carbon fiber yarns and graphite fiber yarns. Alternatively, the conductive wire may be formed into a thread shape by twisting together one or both of ultra-fine conductive metal wires and conductive non-metal wires. The conductive metal wires and conductive non-metal wires may be thin wires having a diameter of several micrometers to several tens of micrometers, but there are no specific limitations.

[0064] 9, in another embodiment, the sewn portion 1122 includes a first section 1122a, a third section 1122c, and a second section 1122b connected in sequence. The third section 1122c is located on the second side B, and the first section 1122a and the second section 1122b are inserted into the solid aerosol-forming substrate 111. When sewing, the first wire 1121 first penetrates the solid aerosol-forming substrate 111 from the first side A to the second side B, is pulled out along the second side B, and then penetrates the solid aerosol-forming substrate 111 again to the first side A. By repeating this process, the first wire 1121 is sewn to the solid aerosol-forming substrate 111, thereby enabling heating of both sides of the solid aerosol-forming substrate 111. When the heater 112 generates heat, it heats and atomizes the solid aerosol-forming substrate 111. Of course, the length of the third section 1122c may be shortened, and the third section 1122c may be slightly exposed to the second side B without being wired to the second side B, and then returned to the first side A along the sewing hole where the first section 1122a is located.

[0065] As can be understood, as shown in Fig. 10, the first wire 1121 may be bent. The bending may be a reciprocating bending method or a wave-shaped bending method. Alternatively, the wire may be curved. The bending method is not limited.

[0066] 11, in order to increase the heat radiation area, the heating element 112 includes a plurality of first wires 1121 located on the same side of the solid aerosol-forming substrate 111. Preferably, the number of first wires 1121 may be two or more. The first wires 1121 may be arranged in a crossing manner to form a network structure. Alternatively, the first wires 1121 may be arranged in parallel, or a combination of the crossing and parallel arrangements may be used.

[0067] Preferably, in some embodiments, the heater 112 further includes a flexible second wire 1124 sewn to the solid aerosol-forming substrate 111. The first wire 1121 and the second wire 1124 are located on opposite sides of the solid aerosol-forming substrate 111, respectively. The first wire 1121 and the second wire 1124 cross each other, thereby providing a more stable bond between the heater 112 and the solid aerosol-forming substrate 111. Typically, the second wire 1124 may be made of an insulating material. By generating heat on the first wire 1121 side of the heater 112, the temperature rise rate during heating is slowed and the heat effect is uniform, preventing a situation in which a portion of the aerosol-forming unit 10 becomes too hot and generates harmful substances. Naturally, the second wire 1124 may be made of a conductive material. In this case, by selecting the first wire 1121 and the second wire 1124 having low resistance, it is possible to avoid situations where the temperature rises too quickly or becomes too high.

[0068] The sheet-shaped solid aerosol-forming substrate 111 is a cloth- or paper-like material produced by extracting flavor plant fibers from herbaceous plants and using a papermaking method or other method. It has a certain degree of hygroscopicity, and when heated, it generates an aerosol with a herbaceous flavor. Furthermore, it may be an atomizable solvent by thoroughly mixing it with a solvent that easily generates vapor, such as propanediol, glycerol, or food flavoring. The solvent or other substance is adsorbed onto the herbaceous plant fibers, and generates an aerosol when the heat generated by the heater 112 reaches a temperature required for atomizing the solvent.

[0069] Because the first wire 1121 is relatively soft, the sheet-like solid aerosol-forming substrate 111 provides support strength to the wire. Furthermore, because the heating element 112 and the aerosol-forming unit 10 are integrally constructed, the heat utilization rate of the heating element 112 is relatively high. This allows for efficient utilization of the solid aerosol-forming substrate 111 to be heated, enabling more sufficient heating. Furthermore, the aerosol-forming unit 10 is discarded after use, which avoids damage to power supply equipment and cleaning, compared with puncture-type heating methods. Furthermore, the more uniform the stitching position and depth, the more uniform the heat generated, and the more uniform the heat acting on the heated aerosol-forming unit 10. This prevents a situation in which a portion of the aerosol-forming unit 10 becomes too hot and generates harmful substances.

[0070] Preferably, as shown in Fig. 13, conductive electrodes 1131 are electrically connected to both ends of the first wire 1121. Furthermore, as shown in Fig. 14, the electrode 113 may further include one or more conductive electrodes 1131 connected between both ends of the first wire 1121 so that the heating element 112 is electrically conductive and generates heat in separate sections. The conductive electrodes 1131 connected to different positions enable different sections of the heating element 112 to participate in heat generation. For example, the heating element 112 may be divided into an upper heating section and a lower heating section, and heating for each section may be achieved by controlling the circuit during use.

[0071] 15, the conductive electrode 1131 includes an extension 1132 extending from the solid aerosol-forming substrate 111. The extension 1132 is a sheet-like conductor and may be in close contact with the conductive electrode 1131 and extend outward, or may be sewn and fixed when the conductive electrode 1131 is sewn. After the solid aerosol-forming substrate 111 is formed by rolling or folding, the extension 1132 is wound or folded onto the outer wall surface of the atomization module 11a, which facilitates electrical connection with the contact point of the heater 20. Of course, the extension 1132 may be omitted. In this case, when the solid aerosol-forming substrate 111 is formed by rolling or folding, the region where the conductive electrode 1131 is located may be provided on the outside.

[0072] 3 and 16, when the conductive electrode 1131 extends from the solid aerosol-forming substrate 111, the conductive electrode 1131 is drawn out from the side wall surface of the aerosol-forming unit 10 and then provided along the circumferential direction of the aerosol-forming unit 10. This allows the conductive electrode 1131 to come into contact with the contact point 211 of the heater 20 no matter how the aerosol-forming unit 10 is turned when inserted or placed in the heater 20.

[0073] 17 and 18, in other embodiments, the conductive electrode 1131 may be provided at the end of the aerosol formation unit 10 after being drawn out from the end of the aerosol formation unit 10, or may be bent to the side wall surface of the aerosol formation unit 10 after being drawn out from the end. In this case, it comes into contact with the contact point 211 at the corresponding position of the heater 20 and is electrically connected.

[0074] Preferably, as shown in FIGS. 13 and 14 , in this embodiment, the solid aerosol-forming substrate 111 includes a heat-generating section 1111 and a covered section 1112. The heating element 112 is provided in the heat-generating section 1111, and the electrode 113 is located in the covered section 1112. Thus, when the substrate is rolled or folded, the covered section 1112 is located on the outermost layer, allowing the rolled or folded heat-generating section 1111 to be covered internally. Heat from the internal heat-generating section 1111 can be transferred to the externally located covered section 1112, heating and atomizing the covered section 1112. In this case, the heating element 112 does not need to directly heat the covered section 1112, preventing the temperature on the outside from becoming too high. Of course, in other embodiments, the heating element 112 may be distributed throughout each region of the solid aerosol-forming substrate 111 without being divided into a heat-generating section 1111 and a covered section 1112.

[0075] In some embodiments, the conductive electrodes 1131 may be formed by sewing the first wire 1121 to the solid aerosol-forming substrate 111. This is convenient for mass and automated production of the nebulization module 11a. As can be appreciated, some of the conductive electrodes 1131 may be woven into the solid aerosol-forming substrate 111 using separate conductive wires.

[0076] Furthermore, when the two conductive electrodes 1131 are located on the same side of the solid aerosol-forming substrate 111, the conductive electrode 1131 and the first wire 1121 are preferably made of the same conductive wire. By being able to complete the conductive electrode 1131 and the heating element 112 in one stitching operation using a single conductive wire, production efficiency is improved.

[0077] Of course, in other embodiments, one conductive electrode 1131 may be located on the first side A and another conductive electrode 1131 may be located on the second side B. The conductive electrode 1131 located on the first side A may be made of the same conductive wire as the first wire 1121. Also, the conductive electrode 1131 located on the second side B may be sewn separately and be in contact with and conductive to the wire of the heating element 112 located on the second side B.

[0078] Additionally, the conductive electrodes 1131 formed by stitching may be provided with a conductive layer, which can stabilize the resistance and facilitate the connection of leads or contacts. In some embodiments, the conductive layer is formed from a conductive paste or conductive adhesive. The conductive adhesive or conductive paste can be coated or printed.

[0079] As can be appreciated, in other embodiments, the conductive layer may be a metal sheet that is in close contact with the conductive electrode 1131. The material of the metal sheet may be nickel, stainless steel, copper, aluminum foil, etc. Alternatively, the metal sheet may be punctured and sewn to the solid aerosol-forming substrate 111 to be fixed and bonded. In this case, the conductive electrode 1131 is supported with a certain degree of hardness, which is advantageous in that it is easier to connect to the contact points in the heater 20.

[0080] 19 and 20 , in some embodiments, the atomization module 11a further includes a heat transfer layer 114 provided on at least one side of the solid aerosol-forming substrate 111 and used for heat transfer. The heat transfer layer 114 is made of an insulating material. By integrally fixing the heat transfer layer 114 and the solid aerosol-forming substrate 111 with the heating element 112, the heat generated by the heating element 112 can be uniformly dispersed through the heat transfer layer 114 rather than concentrating in the area close to the heating element 112. This allows the heat acting on each part of the solid aerosol-forming substrate 111 to be uniform, thereby preventing a situation in which some parts are heated and carbonized while other parts are not heated and are wasted.
