Description

Technical Field

[0001] The present application relates to the field of aerosol supply, and in particular to an aerosol supply system, an atomization component and a heating component thereof. Background Art

[0002] An aerosol supply system refers to a system that internally contains aerosol generating materials and generates aerosol by heating rather than burning the aerosol generating materials (such as tobacco) for users to inhale.

[0003] To heat the aerosol generating materials, a heating component is provided in the aerosol supply system. As Figure 1 shown, the heating component 100 includes a heating part 110 formed by a heating wire, electrode parts 120 on both sides of the heating part 110, and leads 130 connected to the electrode parts 120. The leads 130 are connected to a power source and are used to supply power to the heating part 110 through the electrode parts 120. When the heating part 110 is energized and heated, it can atomize the aerosol generating materials in contact with it. The aerosol generating materials can be liquid, and specifically can be transmitted to the surface of the heating part 110 through a liquid guiding cotton, a ceramic matrix, etc. As Figure 1 shown, the heating part 110 is in the form of a heating mesh. To avoid deformation of the heating mesh, the leads 130 are usually welded to the entire length where the electrode parts 120 are located, so as to thicken the thickness of the electrode parts 120 through the leads 130, better support the heating mesh, and reduce the possibility of deformation.

[0004] The heating part 110 is usually stacked in contact with a porous matrix or sintered on one side of the porous matrix to contact and heat and atomize the liquid aerosol generating materials on the porous matrix. To avoid dry burning of some heating wires that cannot contact the aerosol generating materials, the surface of the porous matrix is usually larger than the surface in contact with the heating part 110, that is, the surface of the porous matrix is very likely to contact at least part of the surface of the electrode parts 120 around the heating part 110 at the same time, resulting in contact between the electrode parts 120 and the aerosol generating materials. Similarly, the leads 130 welded to the electrode parts 120 will also contact the aerosol generating materials.

[0005] The heating part 110 is energized and heated to atomize the aerosol generating materials; while the leads 130 are mainly used for electrical connection, and the heat generated by energization is not mainly used for heating the aerosol generating materials. For this reason, the leads 130 and the heating part 110 usually adopt different resistance materials. For example, the leads 130 often select nickel with a small resistivity. However, nickel will release harmful substances such as heavy metals in a high-temperature environment in contact with the aerosol generating materials, and will be inhaled into the human body along with the aerosol, causing harm to human health.

[0006] Therefore, there is an urgent need for a new technical solution to solve one or more of the above existing technical problems. Summary of the Utility Model

[0102] A consumable is an article that includes or consists of an aerosol - forming material, with part or all of the aerosol - forming material intended to be consumed by a user during use. The consumable can include one or more other components, such as an aerosol - forming material storage area, an aerosol - forming material delivery component, an aerosol - forming area, a housing, a wrapper, a mouthpiece, a filter, and / or an aerosol modifier. The consumable can also include an aerosol generator, such as a heater, which releases heat during use to cause the aerosol - forming material to form an aerosol. The heater can include, for example, a combustible material, a material that can be heated by electrical conduction, or a susceptor.

[0103] A susceptor is a material that can be heated by penetration with a varying magnetic field (such as an alternating magnetic field). The susceptor can be a conductive material such that its penetration by the varying magnetic field causes inductive heating of the material. The heating material can be a magnetic material such that its penetration by the varying magnetic field causes hysteresis heating of the material. The susceptor can be both conductive and magnetic such that the susceptor can be heated by both heating mechanisms. In this document, a device configured to generate a varying magnetic field is referred to as a magnetic - field generator.

[0104] An aerosol modifier is a substance that is typically located downstream of the aerosol - forming area and is configured to modify the generated aerosol, for example, by changing the taste, flavor, acidity, or another property of the aerosol. The aerosol modifier can be provided in an aerosol - modifier release component that is operable to selectively release the aerosol modifier. For example, the aerosol modifier can be an additive or an adsorbent. For example, the aerosol modifier can include one or more of a flavoring, a coloring agent, water, and a carbon adsorbent. For example, the aerosol modifier can be a solid, a liquid, or a gel. The aerosol modifier can be in the form of a powder, a wire, or a granule. The aerosol modifier can be free of filter material.

[0105] An aerosol generator is a device configured to cause an aerosol to be formed from an aerosol - forming material. In some embodiments, the aerosol generator is a heater that is configured to subject the aerosol - forming material to thermal energy in order to release one or more volatiles from the aerosol - forming material to form an aerosol. In some embodiments, the aerosol generator is configured to cause an aerosol to be formed from the aerosol - forming material without heating. For example, the aerosol generator can be configured to subject the aerosol - forming material to one or more of vibration, increased pressure, or electrostatic energy.

[0106] The present disclosure relates to an aerosol supply system (which may also be referred to as a vapor supply system), such as an atomizer or an electronic cigarette. In the following description, the term "electronic cigarette" or "e-cigarette" may sometimes be used, but it will be understood that this term may be used interchangeably with aerosol supply system / device and electronic aerosol supply system / device. Further, as is common in the art, the terms "aerosol" and "vapor" and related terms such as "evaporation", "atomization", and "aerosolization" are generally used interchangeably.

[0107] An aerosol supply system (e-cigarette) typically (although not always) includes modular components, which include a reusable device portion and a replaceable (disposable / consumable) cartridge component. Typically, the replaceable cartridge component will include aerosol generating material and an evaporator (which may be collectively referred to as an "atomizer"), and the reusable device portion will include a power source (e.g., a rechargeable power source) and a control circuit. It will be understood that these different portions may include additional elements depending on the function. For example, the reusable device portion will typically include a user interface for receiving user input and displaying operational status characteristics, and the replaceable cartridge device portion includes a temperature sensor for assisting in controlling temperature in some cases. The cartridge is electrically and mechanically coupled to the control unit for use, for example, using a thread, a bayonet, or a magnetic coupling with appropriately arranged electrical contacts. When the aerosol generating material in the cartridge is depleted, or the user wishes to switch to a different cartridge with a different aerosol generating material, the cartridge can be removed from the reusable component, and a replacement cartridge can be attached in its place. Systems and devices conforming to this type of two-piece modular configuration are generally referred to as two-piece systems / devices.

[0108] Electronic cigarettes generally have a substantially elongated shape. To provide a specific example, some embodiments of the present disclosure will be considered to include such a substantially elongated two-piece system employing a disposable cartridge. However, it will be understood that the basic principles described herein may equally apply to different configurations, such as single-piece systems or modular systems including more than two components, refillable devices and single-use disposables, and other overall shapes, such as so-called pod-mode high-performance devices which typically have a cartridge-like shape. More generally, it will be understood that certain embodiments of the present disclosure are based on an aerosol supply system which is operationally configured to provide functions in accordance with the principles described herein, and the construction of the system configured to provide the functions of certain embodiments of the present disclosure is not of primary importance.

[0109] As described in the background art, the way the lead overlaps and contacts the entire length of the electrode part makes the lead in contact with the high-temperature liquid aerosol generating material relatively long, resulting in the problem of excessive release of harmful substances. For this reason, the present application creatively proposes to set the length of the part (the first lead segment) where the lead overlaps and contacts the electrode part to be less than the length of the electrode part, that is, to set the lead to only overlap and contact a part of the electrode part, so as to reduce the length of the lead that may come into contact with the liquid aerosol generating material, and thus reduce the amount of harmful substances released by the lead.

[0110] Embodiment 1

[0111] The heating component is a component in the aerosol supply system that heats the aerosol generating material to generate aerosol. Embodiment 1 of the present application introduces the heating component in detail.

[0112] Figures 2 to 7 are three-dimensional structure diagrams of different heating components of the aerosol supply system provided by different embodiments of the present application. Among them Figures 2 to 4 shows a heating component with a flat heating mesh, Figures 5 to 7 shows a heating component with a C-shaped heating mesh.

[0113] As Figures 2 to 7 shown, the heating component 200 includes a heating part 210 composed of heating wires 211, an electrode part 220 electrically connected to the heating part 210, and a lead 230 electrically connected to the electrode part 220. The heating part 210 is usually arranged in the middle part, and the electrode part 220 is arranged around the heating part 210. The lead 230 is connected to a power source and is used to deliver current to the electrode part 220 and then to the heating part 210. The heating part 210 is energized to generate heat to heat and atomize the aerosol generating material in contact with it.

[0114] It should be noted here that in the embodiments of the present application, the shape of the heating part 210 is not specifically limited. Without departing from the concept of the present application, the user can set it according to actual needs. As an exemplary rather than restrictive illustration, in one of the embodiments, the heating wire 211 can be arranged in a serpentine shape to form a serpentine heating part. In an alternative embodiment, as Figures 2 to 7 shown, the heating part 210 can be arranged in the form of a heating mesh. Among them, the mesh holes of the heating mesh have various types, such as any one of circular or polygonal shapes.

[0115] It can be understood that the heating mesh can have various possible settings. As Figures 2 to 4 shown, the heating mesh is a flat heating mesh. The flat heating mesh can have various possible shapes, such as the rectangular flat heating mesh shown in FIGS. 2 to 4. And Figures 5 to 7A C-shaped heating mesh formed by winding a heating wire 211 is provided. Without departing from the concept of this application, the heating mesh can also be in various other possible forms, and this application does not make specific limitations thereto.

[0116] It should be noted here that in the embodiments of this application, the material of the heating part 210 is not specifically limited. By way of example and not limitation, the material of the heating part 210 can be selected from at least one of iron-chromium-aluminum, nickel-chromium, stainless steel, and titanium alloy.

[0117] It should be noted here that in the embodiments of this application, the formation method of the electrode part 220 is not specifically limited. Without departing from the concept of this application, the user can set it according to actual needs. As an exemplary but non-limiting illustration, the electrode part 220 in the embodiments of this application is integrally formed with the heating part 210. Of course, in alternative embodiments, the electrode part 220 can also be separately formed from the heating part 210 and connected to the heating part 210 by other means such as welding and clamping.

[0118] It should be noted here that in the embodiments of this application, the shape of the electrode part 220 is not specifically limited. Without departing from the concept of this application, the user can set it according to actual needs. As an exemplary but non-limiting illustration, as Figures 2 to 4 shown, the electrode part 220 in the embodiments of this application is a strip-shaped electrode part 220 formed around the heating part 210. In another embodiment, each electrode part 220 can be arranged around the heating part 210 and form a semi-enclosing shape.

[0119] It should be noted here that in the embodiments of this application, the number of the electrode parts 220 is not specifically limited. Without departing from the concept of this application, the user can set it according to actual needs. As an exemplary but non-limiting illustration, as Figures 2 to 4 shown, the electrode part 220 in the embodiments of this application includes two. Of course, in alternative embodiments, the number of the electrode parts 220 can be three or more.

[0120] It should be noted here that in the embodiments of this application, the material of the electrode part 220 is not specifically limited. By way of example and not limitation, the material of the electrode part 220 can be selected from at least one of iron-chromium-aluminum, nickel-chromium, stainless steel, and titanium alloy.

[0121] This application provides two specific setting methods for the heating part 210 and the electrode part 220:

[0122] As Figures 2 to 4 shown, the heating component 200 includes two electrode parts 220, the heating part 210 is a flat heating mesh, and the two electrode parts 220 are arranged on two opposite sides of the flat heating mesh.

[0123] AsFigures 5 to 7 As shown, the heating component 200 includes two electrode portions 220. The heating portion 210 is a C-shaped heating mesh, and the two electrode portions 220 are disposed on two opposite sides in the circumferential direction of the C-shaped heating mesh.

[0124] To reduce the harmful substances released by the lead 230, in this application, it is arranged that the lead 230 only overlaps and contacts a partial length of the electrode portion 220 to reduce the length of the lead in contact with the aerosol generating material. Specifically, as Figures 2 to 7 shown, the electrode portion 220 has a first length along its own length extension direction, and a lead 230 is arranged. The portion in overlapping contact with the electrode portion 220 forms a first lead segment 231, and the first lead segment 231 has a second length along the length extension direction of the electrode portion 220; wherein the first length is greater than the second length.

[0125] This application does not specifically limit the second length. On the premise of not violating the concept of this application, the user can set it according to actual needs. As an exemplary rather than restrictive illustration, the second length in the embodiments of this application is 1 / 2 or less of the first length. Considering the connection stability between the electrode portion 220 and the lead 230, the second length is 1 / 4 or more of the first length. It should be noted that in extreme cases, the lead 230 and the electrode portion 220 can merely be butt-jointed at their ends, and at this time, the second length corresponding to the first lead segment 231 can be considered to be almost zero.

[0126] It should be noted that the arrangement of the electrode portion 220 is diverse. It can extend along a single direction or can be bent. Therefore, the above-mentioned length extension direction does not necessarily mean a single direction.

[0127] Here, it should be noted that in the embodiments of this application, the material of the lead 230 is not specifically limited. As an example rather than a limitation, the material of the lead 230 can be selected from at least one of nickel or SUS316 (stainless steel 316).

[0128] In the embodiments of this application, the connection manner between the electrode portion 220 and the first lead segment 231 is not specifically limited. On the premise of not violating the concept of this application, the user can set it according to actual needs. As an exemplary rather than restrictive illustration, the electrode portion 220 and the first lead segment 231 can be connected by welding or clamping or pressing.

[0129] After considering the above settings for the lead 230, there is no lead 230 at some electrode parts 220 to assist, thus reducing the supporting force for the heating part 210, resulting in the heating part 210 with a mesh or serpentine shape being prone to deformation. Therefore, in a further embodiment of the present application, the cross-sectional area of the electrode part 220 is set to be larger than the cross-sectional area of the heating wire 211 of the heating part 210, so as to increase the thickness or width of the electrode part 220 to provide better support for the heating part 210.

[0130] It should be noted here that in the embodiment of the present application, various possible ways can be adopted to increase the cross-sectional area of the electrode part 220. For example, during mold forming, the thickness of the electrode part 220 can be directly increased. In another feasible embodiment, as Figures 2 to 7 shown, the side 221 connected to the outer periphery of the heating part 210 is bent to form a hem 222, thereby forming the electrode part 220. After hemming, the thickness is doubled, which can obviously improve the support of the electrode part 220 for the heating part 210. In some embodiments, the side 221 is integrally formed with the heating part 210 and has the same thickness as the heating wire 211. After hemming, the thickness is twice that of the heating wire 211.

[0131] In addition to the above first lead segment 231, as Figures 2 to 7 shown, the lead 230 also has a second lead segment 232 that does not overlap with the electrode part 220. Since the second lead segment 232 does not need to consider the electrical connection with the electrode part 220, protection can be provided for the second lead segment 232 to reduce the release of harmful substances. Specifically, as Figure 2 、 3 、5、6 shown, the heating component 200 further includes a protective sleeve 240 sleeved at least on the second lead segment 232. By adding the protective sleeve 240, the amount of harmful substances released from the second lead segment 232 is reduced.

[0132] Furthermore, the first lead segment 231 has a first surface in contact with the electrode part 220 and a second surface facing away from the first surface. Since the second surface is not in direct contact with the electrode part 220, a protective sleeve 240 can be provided on the second surface. In the embodiment of the present application, the protective sleeve 240 can be provided only on the second lead segment 232, only on the second surface, or on both of them simultaneously.

[0133] It should be noted here that in the embodiment of the present application, the material of the protective sleeve 240 is not specifically limited. Without departing from the concept of the present application, the user can set it according to actual needs. As an exemplary rather than restrictive description, the protective sleeve 240 in the embodiment of the present application is prepared from polyether ether ketone with high temperature resistance and metal radiation resistance.

[0134] In addition to the protective sleeve, in some embodiments of the present application, a protective layer may also be coated on the second lead segment 232. This protective layer can reduce the amount of harmful substances released outward at the second lead segment 232. Specifically, a material with good resistance to metal radiation, such as silver, can be selected for the protective layer.

[0135] Similar to the protective sleeve 240, the first lead segment 231 has a first surface in contact with the electrode portion 220 and a second surface facing away from the first surface. Since the second surface is not in direct contact with the electrode portion 220, a protective layer can be coated on the second surface.

[0136] Furthermore, if a conductive protective layer, such as a silver protective layer, is used, the protective layer can be coated on both the first surface and the second surface of the first lead segment 231. Therefore, in the embodiments of the present application, according to needs, a protective layer can be coated on at least one of the second lead segment 232, the second surface, and the first lead segment 231.

[0137] It should be noted that in the embodiments of the present application, the above-mentioned first surface can be broadly understood to include the case of a line. For example, when the first lead segment 231 is a cylindrical segment and the surface of the electrode portion 220 facing the first lead segment 231 is a plane, the first lead segment 231 and the electrode portion 220 are actually in line contact, and the part outside the line contact is the second surface.

[0138] Considering the electrical connection between the lead 230 and the power supply, it can be set that the lead 230 further includes a third lead segment 233 in direct contact with the power supply, and no protective sleeve or protective layer may be provided on the third lead segment 233. Or a protective sleeve and a protective layer can be provided in a manner similar to that of the first lead segment 231.

[0139] The second lead segment 232 can be provided with protection, while in most cases, it is difficult to perform the above-mentioned protection or only partial protection on the first lead segment 231 that overlaps and contacts the electrode portion 220. From this perspective, even if the contact with the aerosol material is not considered, the amount of harmful substances released by the second lead segment 232 can be made lower than that of the first lead segment 231 through setting. Therefore, the shorter the length of the first lead segment 231 that overlaps and contacts the electrode portion 220, the less harmful substances are released by the entire lead 230.

[0140] In the embodiments of the present application, the number of leads 230 is the same as that of the electrode portions 220. When the number of the electrode portions 220 and the leads 230 is two or more, there are various possible setting methods for the leads 230 and the electrode portions 220. Such as Figures 2 to 4As shown, there are two electrode parts 220 and two leads 230. Each electrode part 220 has a first end 223 and a second end 224. The two first ends 223 are close to each other, while the first end 223 of one and the second end 224 of the other are far from each other. And the two leads 230 are each connected to the first end 223 of the corresponding electrode part 220. In an alternative embodiment, one of the two leads 230 is connected to the first end 223 of the corresponding electrode part 220, and the other is connected to the second end 224 of the corresponding electrode part 220.

[0141] To further provide support for the heating part 210, in another embodiment of the present application, as Figure 8 shown, the heating component 200 further includes a support part 250 to provide support for the heating part 210 in the first direction; the electrode part 220 provides support for the heating part 210 in the second direction; the first direction and the second direction are arranged at an angle, preferably perpendicular.

[0142] As Figure 8 shown, the support part 250 and the electrode part 220 can be integrally semi-enclosed around the outer periphery of the heating part 210 and surround the heating part 210. By providing two support parts 250 and two electrode parts 220, it can be integrally enclosed around the outer periphery of the heating part 210.

[0143] Embodiment Two

[0144] In a second aspect of the embodiments of the present application, an atomizing component of an aerosol supply system is disclosed. As Figure 9 、 10 shown, the atomizing component 20 includes:

[0145] A porous matrix 300, which contacts the heating part 210 to conduct oil of the liquid aerosol generating material to the heating part 210;

[0146] The heating component 200 according to any one of the first aspects, where the heating part 210 is used to heat and atomize the liquid aerosol generating material to generate aerosol.

[0147] As Figure 9 shown, the porous matrix 300 can be stacked with the heating component 200 to form the atomizing component 20.

[0148] In an alternative embodiment, as Figure 10 shown, the porous matrix 300 and the heating component 200 are integrated, such as sintering the heating component 200 on the porous matrix 300. The porous matrix 300 can be a ceramic matrix.

[0149] The present application does not specifically limit the formation method of the heating component 200. By way of example and not limitation, in the present application, the heating component 200 is prepared on the surface of the porous matrix 300 by a thick film printing process or a vacuum evaporation process.

[0150] As described in the first embodiment, along the length extension direction of the electrode part 220, the overlapping contact length of the lead wire 230 and the electrode part 220 is less than the length of the electrode part 220. In practical applications, whether the lead wire 230 is likely to contact the aerosol generating material is also related to the overlapping length of the lead wire 230 and the porous substrate 300. Therefore, in a further embodiment, along the length extension direction of the electrode part 220, the overlapping length of the lead wire 230 and the porous substrate 300 is less than the length of the porous substrate 300. In this way, the lead wire 230 contacts the liquid aerosol generating material on the porous substrate 300 as little as possible.
