Description

Technical Field

[0001] This application relates to the field of aerosol supply technology, and in particular to a heating element, a smoke cartridge, and an aerosol supply system for an aerosol supply system. Background Technology

[0002] An aerosol supply system refers to a system that contains aerosol-generating materials and produces aerosols for users to inhale by heating rather than burning the aerosol-generating materials (such as tobacco). To heat the aerosol-generating materials, the aerosol supply system includes heating elements that generate heat through electrical current.

[0003] Traditional heating elements typically employ a single heating zone, applying the same temperature to all aerosol-generating materials. However, aerosol-generating materials (such as e-liquids, pharmaceutical solutions, or industrial formulations) are usually composed of multiple substances, each with its own optimal atomization temperature. Using a single heating temperature may lead to overheating and decomposition of low-temperature substances or insufficient atomization of high-temperature substances, affecting aerosol quality and user experience. Furthermore, most current heating elements have poor compatibility with aerosol-generating materials, easily resulting in severe carbon buildup and degraded flavor, ultimately failing to meet the user's overall sensory experience expectations. Utility Model Content

[0004] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a heating element, a smoke cartridge, and an aerosol supply system for an aerosol supply system, to solve the technical problem of poor compatibility between the heating element and the aerosol generating material.

[0019] In one technical solution of the heating component of the aforementioned aerosol supply system, the heating element has a mesh structure.

[0020] In one technical solution of the heating component of the aforementioned aerosol supply system, the heating element includes a heating structure capable of generating heat when energized, the heating structure having a bend, and the inner chamfer of the bend being rounded.

[0021] In one technical solution of the heating component of the aforementioned aerosol supply system, the radius of the rounded corner is 0.05-0.10 mm.

[0073] Aerosol-generating materials are materials capable of generating aerosols, for example, when heated, irradiated, or electrified in any other way. Aerosol-generating materials may be in solid, liquid, or gel form, and may or may not contain active substances and / or fragrances. In some embodiments, aerosol-generating materials may include “amorphous solids,” which may alternatively be referred to as “monolithic solids” (i.e., non-fibrous).

[0078] Consumables are articles comprising or composed of aerosol-generating materials, some or all of which are intended to be consumed by a user during use. Consumables may include one or more other components, such as an aerosol-generating material storage area, an aerosol-generating material delivery component, an aerosol-generating area, a housing, packaging paper, a nozzle, a filter, and / or an aerosol modifier. Consumables may also include an aerosol generator, such as a heater, which releases heat during use to cause the aerosol-generating material to generate an aerosol. The heater may, for example, comprise a combustible material, a material that can be heated by electrical conduction, or a sensor.

[0079] A sensor is a material that can be heated by being penetrated by a changing magnetic field (such as an alternating magnetic field). A sensor can be a conductive material, such that penetration by a changing magnetic field results in inductive heating of the heating material. A heating material can be a magnetic material, such that penetration by a changing magnetic field results in hysteresis heating of the heating material. A sensor can be both conductive and magnetic, allowing it to be heated by both heating mechanisms. In this paper, a device constructed to generate a changing magnetic field is referred to as a magnetic field generator.

[0080] Aerosol modifiers are substances typically located downstream of the aerosol generation region, configured to modify the generated aerosols, for example, by altering their taste, flavor, acidity, or other properties. Aerosol modifiers can be disposed in aerosol modifier release components operable to selectively release the aerosol modifier. For example, aerosol modifiers can be additives or adsorbents. For example, aerosol modifiers may include one or more of fragrances, colorants, water, and carbon adsorbents. For example, aerosol modifiers can be solid, liquid, or gel. Aerosol modifiers can be in powder, filament, or granular form. Aerosol modifiers may not contain filter material.

[0081] An aerosol generator is a device configured to cause the generation of aerosols from an aerosol-generating material. In some embodiments, an aerosol generator is a heater configured to subject the aerosol-generating material to heat energy in order to release one or more volatiles from the aerosol-generating material to form an aerosol. In some embodiments, an aerosol generator is configured to cause the generation of aerosols from an aerosol-generating material without heating. For example, an aerosol generator may be configured to subject the aerosol-generating material to one or more of vibration, increased pressure, or electrostatic energy.

[0082] This disclosure relates to aerosol delivery systems (which may also be referred to as vapor delivery systems), such as aerosol sprayers or electronic cigarettes. In the following description, the terms "electronic cigarette" or "electronic cigarette" may sometimes be used, but it will be understood that this term is used interchangeably with aerosol delivery systems / devices and electronic aerosol delivery systems / devices. Furthermore, as is common in the art, the terms "aerosol" and "vapor," as well as related terms such as "evaporation," "atomization," and "aerosolization," are generally used interchangeably.

[0083] Aerosol delivery systems (electronic cigarettes) typically (though not always) comprise modular components, including reusable device parts and replaceable (disposable / consumable) cartridge parts. Typically, the replaceable cartridge part will include aerosol generating material and an vaporizer (which may be collectively referred to as an "atomizer"), and the reusable device part will include a power source (e.g., a rechargeable power supply) and control circuitry. It will be understood that these different parts may include additional components depending on their function. For example, the reusable device part will typically include a user interface for receiving user input and displaying operational status characteristics, and the replaceable cartridge device part may include, in some cases, a temperature sensor to aid in temperature control. The cartridge is electrically and mechanically connected to the control unit for use, for example, using threads, bayonet connections, or magnetic connections with suitably arranged electrical contacts. When the aerosol generating material in the cartridge is depleted, or when the user wishes to switch to a different cartridge with a different aerosol generating material, the cartridge can be removed from the reusable part, and a replacement cartridge can be attached to its appropriate position. Systems and devices that conform to this type of two-piece modular configuration can generally be referred to as two-piece systems / devices.

[0084] Electronic cigarettes typically have a generally elongated shape. For the sake of specific examples, some embodiments of this disclosure will be considered to include such a generally elongated two-piece system employing a disposable cartridge. However, it will be understood that the basic principles described herein can be equally applied to different constructions, such as single-piece systems or modular systems comprising more than two components, refillable devices and single-use disposable items, as well as other overall shapes, such as high-performance devices based on a so-called box-shaped pattern that typically has a box-like shape. More generally, it will be understood that some embodiments of this disclosure are based on aerosol delivery systems that are operatively configured to provide the functionality according to the principles described herein, and the construction aspects of the system configured to provide the functionality according to some embodiments of this disclosure are not of primary importance.

[0085] As described in the background section, heating aerosol-generating materials at a single temperature may lead to overheating and decomposition of low-temperature substances or insufficient atomization of high-temperature substances, affecting aerosol quality and user experience. Furthermore, most current heating elements have poor compatibility with aerosol-generating materials, easily resulting in severe carbon buildup and deteriorated taste, causing the user's overall sensory experience to fall short of expectations. Therefore, this application's embodiments creatively propose configuring the heating element with multiple heating zones, and configuring these zones to operate at different preset temperatures under the same atomization mode. This allows different heating zones to atomize different substances in the aerosol-generating material, improving the compatibility between the heating element and the aerosol-generating material, significantly reducing carbon buildup, and providing a superior user experience.

[0086] It should be noted that the heating component of the aerosol supply system provided in this application embodiment can be applied to both pen-type and box-type aerosol supply systems, and no specific limitation is made here.

[0087] Example 1

[0088] A heating element is a component in an aerosol supply system that heats aerosol-generating materials to produce aerosols. Embodiment 1 of this application describes a heating element for heating liquid aerosol-generating materials (such as e-liquid).

[0089] Figure 1 This is a schematic diagram of the structure of the heating component of the aerosol supply system provided in the embodiments of this application. Figure 2 This is an exploded view of the heating component of the aerosol supply system provided in the embodiments of this application. Figure 3 This is a schematic diagram of a portion of the structure of the heating component of the aerosol supply system provided in the embodiments of this application, referring to... Figures 1 to 3 As shown, the heating component includes at least a heating element 100 and multiple heated areas 200 formed by the heating element 100. The multiple heated areas 200 are configured to be at different preset temperatures in the atomization mode. Here, the atomization mode refers to the same atomization mode, that is, the aerosol supply system uses the same atomization parameters (such as the same power) to heat the aerosol generating material to produce an aerosol for the user to inhale.

[0090] It is understandable that the heating area refers to the part of the heating element 100 that can generate heat when it is powered on. The heat generated when these parts are heated is transferred to the adjacent area on the heating component 100 through heat conduction, thereby forming a region with increased temperature on the heating component 100 and the adjacent area. This part of the region is called the "heated area".

[0091] Aerosol generating materials (including but not limited to tobacco extracts) typically contain a variety of different substances, such as nicotine and flavorings, each with its own optimal excitation temperature. The flavor of the aerosol generated by atomizing these materials is significantly affected by temperature. Temperature changes directly alter the atomization effect, the volatility characteristics of the substances in the aerosol generating material, and the user's sensory experience. For example, if the atomization temperature is low, some volatile flavorings (such as fruity or minty flavors) will be released weakly, resulting in a milder taste. If the atomization temperature is high, the aroma will be stronger, but some components (such as sweeteners) may overheat and decompose, producing a bitter or burnt taste.

[0092] Based on this, the embodiments of this application configure the heating component to include multiple heated areas 200, and determine the preset temperature corresponding to each heated area 200 according to the optimal excitation temperature of different substances in the aerosol generating material to be atomized, so that each heated area 200 is adapted to at least one substance, that is, each heated area 200 can be at the optimal excitation temperature of at least one substance in the aerosol generating material, thereby improving the compatibility between the heating component and the aerosol generating material, so that the flavor of the final generated aerosol for the user to inhale is optimal.

[0093] In some specific embodiments, the preset temperature corresponding to each heating zone 200 is determined according to the difference in volatility of each substance in the aerosol generating material to be atomized; for example, the preset temperature corresponding to some heated zones 200 is set as the optimal activation temperature of nicotine, and the preset temperature corresponding to other heated zones 200 is set as the optimal activation temperature of edible flavorings, etc., which will not be listed here one by one.

[0094] Understandably, the flavor profile of aerosols is the result of multiple factors working together. Besides the optimal excitation temperature, the content of substances is also a key influencing factor. The optimal excitation temperature determines the volatilization efficiency and the degree of chemical reaction of each component, while the content of substances directly affects the concentration, complexity, and balance of the flavor. For example, some substances (such as vanillin) exhibit a sweet flavor at low concentrations but produce a pungent taste at high concentrations.

[0095] Based on this, in some embodiments of this application, the heating regions 200 for different substances in the atomized aerosol generating material are configured to have different areas. Furthermore, the area of ​​each heating region 200 is determined according to the content of each substance in the aerosol generating material. By controlling the area of ​​each heating region 200 for atomizing different substances, the composition and content of each substance in the atomized aerosol are controlled, thereby ensuring that the generated aerosol has optimal flavor.

[0096] In some specific embodiments, the heating element 100 includes a heating structure 110 capable of generating heat when energized. The heating structure 110 includes at least two sections with the same wire diameter but different resistivities. That is, the heating element 100 can be made of materials with different resistivities, and the heating structure 110 has a higher resistivity in the heated region 200 with a higher preset temperature. In other words, by matching the preset temperature requirements of each heated region 200 with differentiated resistivity materials, efficient and precise atomization of the aerosol generating material is achieved. In specific implementations, temperature self-adaptation can be achieved through the intrinsic properties of material resistivity. For example, the heating structure 110 corresponding to each heated region 200 can be configured to be made of materials with different resistivities, and the resistivity is positively correlated with the corresponding preset temperature; that is, the heating structure 110 has a higher resistivity in the heated region 200 with a higher preset temperature. For the heating structure 110 corresponding to the high-temperature region, a high-resistivity material (such as nickel-chromium alloy) is selected to generate higher Joule heat at the same voltage; for the heating structure 110 in the low-temperature region, a low-resistivity material (such as doped tin oxide ceramic) is used to achieve gentle heating.

[0097] In some specific embodiments, the heating element 100 includes a heating structure 110 capable of generating heat when energized, and the heating structure 110 includes at least two segments with different resistance values. That is, a differentiated resistance structure is designed based on multiple resistance values ​​of homogeneous materials, thereby achieving multiple heated areas 200 at different preset temperatures in atomization mode. It is understood that under the same voltage, a higher resistance value results in higher heating power. In specific implementations, the heating structures 110 corresponding to all heated areas 200 use the same resistivity material, and the structural design ensures that the resistance value of the heating structure 110 in each area is positively correlated with the preset temperature; that is, in the heated area 200 with a higher preset temperature, the resistance value of the heating structure 110 is higher. For example, a heating wire with the same resistivity (such as a nickel-chromium alloy) can be used as the base material, and the resistance value can be adjusted by changing the cross-sectional area (or wire diameter), length, chamfer shape, and fillet diameter of the heating element. For the heating element 100 in the high-temperature region, a long and thin heating wire can be used; for the heating element 100 in the low-temperature region, a short and thick heating wire can be used.

[0098] In some specific embodiments, the material of the heating element 100 may be selected from one or a combination of several of iron-chromium-aluminum, nickel-chromium, stainless steel and titanium alloys.

[0099] In some specific embodiments, at least one heated region 200 comprises a set of discretely distributed sub-regions having the same temperature. That is, at least one heated region 200 comprises a plurality of discretely distributed sub-regions, each sub-region having the same temperature.

[0100] In some specific embodiments, the multiple heated areas 200 are discretely distributed. For example, the multiple heated areas 200 are arranged in a honeycomb or matrix pattern, which is not specifically limited here. That is to say, the heating space in the embodiments of this application can be divided into multiple sub-regions, and each sub-region may include one or more heated areas 200 with different preset temperatures.

[0101] In other specific embodiments, multiple heated regions 200 are arranged according to preset rules. Specifically, the multiple heated regions 200 are spatially arranged according to preset geometric rules, including but not limited to being arranged side-by-side along a preset direction, arranged in a ring-shaped radial pattern, and arranged in a spiral pattern. For example, each heated region 200 is arranged linearly along the length or radial direction of the system. Alternatively, each heated region 200 is arranged in a ring-shaped radial pattern with the center point of the heating element 100 as a reference.

[0102] In some specific embodiments, the heated area 200 with a higher preset temperature is closer to the center of the heating element 100. That is, in this embodiment, the temperature distribution of the heated area 200 exhibits a gradient characteristic of high temperature at the center and low temperature at the periphery, and the heated area 200 with a higher preset temperature is closer to the center of the heating element 100. In specific implementation, the high-temperature central area can be achieved using a high-density heating structure. Adopting a high-temperature central layout can reduce heat radiation loss, conform to the natural thermodynamic distribution law, and the gradient temperature field can better match the volatilization characteristics of various substances in the aerosol generating material, while also reducing the heat load on peripheral components.

[0103] Reference Figure 3 and Figure 4 As shown, in this embodiment of the application, by way of example and not limitation, the heated region 200 is configured to include at least a first region 210, a second region 220, a third region 230, and a fourth region 240 according to the atomization temperature of each substance in the aerosol generating material to be atomized. The preset temperatures corresponding to the first region 210, the second region 220, the third region 230, and the fourth region 240 are [50℃-100℃), [100℃-150℃), [150℃-200℃), and [200℃-250℃], respectively. Further reference... Figure 4 As shown, the first region 210, the second region 220, the third region 230, and the fourth region 240 are discretely distributed on the heating element 100. The heated regions with higher preset temperatures are closer to the center of the heating element 100.

[0104] In some specific embodiments, the area ratio of the first region 210, the second region 220, the third region 230 and the fourth region 240 is 7.97:4.52:3.48:6.19.

[0105] Further reference Figures 2 to 3 As shown in the embodiments of this application, the heating element 100 includes a heating structure 110 capable of generating heat when energized. The heating structure 110 is generally a mesh structure with perforated holes, which can be circular or polygonal. The heating structure 110 can be flat or coiled into a tube; this application does not impose specific limitations on this. In some specific embodiments, the perforated holes of the mesh structure are rhomboid. The heating structure 110 has bends. It is understood that if the bends are sharp, the temperature of the corresponding area will be too high due to the overlap of the two heating wires, leading to easy carbon buildup. To address this problem, in the embodiments of this application, the inner chamfer of the bend is rounded to avoid excessive temperature in the corresponding area, thereby reducing the carbon buildup problem.

[0106] Understandably, if the radius of the corner is too small, the temperature in the corresponding area will be too high, which is not conducive to processing, while if the radius of the corner is too large, it will easily lead to too low a temperature. Based on this, in the embodiments of this application, the radius of the corner is set to be between 0.05-0.10mm, so as to avoid carbon buildup caused by excessive temperature and meet the atomization temperature requirements of the aerosol generating material.

[0107] Further reference Figure 2 and Figure 3 As shown in the embodiment of this application, the heating element 100 includes a heating structure 110 and two electrical connection portions 120 and 130. The heating structure 110 is configured to heat multiple heated areas 200 to generate aerosols from the aerosol-generating material. The two electrical connection portions 120 and 130 are configured to be electrically connected to the power supply electrodes of the system to provide power to the heating structure 110. The heating element 100 also includes some support portions, such as 140 and 150 as shown in the figure. These parts do not generate heat after the heating element is energized. The resistance of the heating element 100 is mainly composed of the heating structure 110 and the electrical connection portions 120 and 130. Although the electrical connection portions 120 and 130 generate heat when energized, their main function is electrical connection, not heating of the aerosol-generating material. They can be called ineffective resistances, generating ineffective power consumption.

[0108] In some specific embodiments, the resistivity of at least a portion of the structure of the two electrical connections 120 and 130 is less than the resistivity of the heating structure 110. By setting the resistivity of at least a portion of the structure of the electrical connections to be less than that of the heating structure 110, the ineffective resistance value can be reduced, thereby reducing ineffective power consumption and energy waste. Correspondingly, if the effective resistance remains unchanged, the proportion of effective resistance increases, and the effective power consumption increases accordingly; if the overall resistance of the heating element 100 remains unchanged, the effective resistance increases, the proportion of effective resistance further increases, and the effective power consumption increases accordingly. This improves the atomization capability of the system.

[0109] Further reference Figures 1 to 3 As shown in the embodiments of this application, the heating component further includes an oil guide 300, configured to absorb aerosol-generating materials. The heating element 100 has a contact surface that contacts the oil guide 300, and the oil guide 300 is pressed against the contact surface. In some specific embodiments, the oil guide 300 can be an oil guide such as cotton or ceramic; in other specific embodiments, the oil guide 300 can be a multi-layered porous structure. As an illustrative and not limiting description, the oil conductivity of the side of the oil guide 300 near the heating element 100 is lower than that of the side away from the heating element 100, and the oil absorption rate of the side of the oil guide 300 near the heating element 100 is higher than that of the side away from the heating element 100. This results in a higher oil conductivity in the portion of the oil guide 300 near the heating element 100, improving its oil conduction efficiency, while a higher oil absorption rate in the portion away from the heating element 100, increasing the amount of oil absorbed at the heating element 100.

[0110] Further reference Figures 1 to 3 As shown in the embodiments of this application, the heating component further includes a silicone element 400. The silicone element 400 presses the heating element 100 onto the oil guide body 300. By adjusting the position of the silicone element 400, the pressing force between the heating element 100 and the oil guide body 300 can be adjusted, thereby precisely controlling the flow rate of the aerosol generating material to the heater, ensuring that the heater generates a stable aerosol and provides an excellent sensory experience. In some specific embodiments, the silicone element 400 is provided with multiple grooves, which can accommodate excess aerosol generating material or condensate to prevent leakage.

The air inlet can be located at the distal end or at other locations within the housing 4000.

[0118] The housing 4000 forms a receiving space and air passage.

The atomization chamber is in fluid communication with the liquid reservoir 2000, allowing the aerosol-generating material in the liquid reservoir 2000 to enter the atomization chamber and be heated by the heating element.

[0119] The air inlet, atomizing chamber, and air outlet are connected to form the air passage inside the housing. When the user inhales, outside air enters through the air inlet, passes through the atomizing chamber to carry away the aerosol inside, and then flows out to the user through the air outlet.
