Description

Technical Field

[0001] The present invention relates to the field of aerosol supply, and particularly to a heating element of an aerosol supply system, an aerosol supply system and a control method thereof. Background Art

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

[0003] An aerosol supply system generally includes a housing, a receiving cavity provided in the housing, an atomizer, a power supply and a controller. The receiving cavity is used to accommodate aerosol-forming materials. The atomizer includes an atomization cavity and a heating element provided in the atomization cavity.

[0004] It can be understood that some components in aerosol-forming materials such as e-liquid will carbonize at high temperatures and deposit on the heating element to cause carbon accumulation, which affects the use of the heating element. To meet the needs of users for different flavors, there are currently various e-liquids with different components on the market. When these e-liquids with different components are atomized at high temperatures, the amount of carbon accumulation generated on the heating element may be different. For example, some e-liquids have a high sugar content and are more likely to accumulate carbon. While some e-liquids have a low sugar content and less carbon accumulation. For e-liquids with different carbon accumulation amounts, different atomization modes need to be adopted. For example, when atomizing e-liquids that are prone to carbon accumulation, a low-energy atomization mode is adopted; when atomizing e-liquids that are not prone to carbon accumulation, a high-energy atomization mode is adopted. In addition, for e-liquids with different components, different energy atomization modes are also required to achieve their respective optimal atomization states. Even for the same e-liquid, different users pursue different inhalation experiences. For example, some people like to inhale high-concentration aerosol, while some people like to inhale low-concentration aerosol. All of these require different energy atomization modes to achieve.

[0005] The current aerosol supply systems either have only one heating element or two identical heating elements for replacement when one heating element fails. Whether it is one or two identical heating elements, under the same power supply power, the energy they can provide by themselves is the same. Moreover, the same heating element corresponds to the same optimal power supply power. If different power supply powers are set to achieve different energies of the heating element, it is very likely that the heating element will be damaged or unable to reach the optimal atomization state due to the mismatch between the heating element and the power supply power. It can be seen that the heating elements in the current aerosol systems cannot meet the requirements of different atomization modes of the system.

[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 Invention

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.

[0117] An aerosol generator is a device configured to cause an aerosol to be generated 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 generated 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.

[0118] 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.

[0119] 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. Generally, the replaceable cartridge component will include an 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 operating state characteristics, and the replaceable cartridge device portion includes a temperature sensor for assisting in controlling the 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 is 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.

[0120] Electronic cigarettes typically have a generally elongated shape. To provide a specific example, some embodiments of the present 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 may equally apply to different configurations, such as a one-piece system or a modular system including more than two components, a refillable device and a single-use disposable article, and other overall shapes, such as those based on the so-called pod-mode high-performance devices which typically have a box-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 aspects of a system configured to provide the functions of certain embodiments of the present disclosure are not of primary importance.

[0121] As described in the background art, the heating elements provided in the current aerosol supply system can only meet the requirements of one atomization mode. Therefore, the embodiments of the present invention creatively propose to provide a plurality of heating elements that can obtain different energy densities after being energized to correspond to different atomization modes of the system. These atomization modes can be, for example, different e-liquids require different energies due to carbon deposition, different e-liquids require different energies to reach the optimal atomization state, and different users pursue different aerosol concentration experiences and require different energies. The matching of different atomization modes with different energy densities can achieve a better atomization state in any atomization mode, improving the user experience. The heating elements with different energy densities corresponding to different atomization modes can also enable better matching of the heating elements with e-liquids, power supply, etc., avoiding problems such as carbon deposition and damage caused by excessive power, and improving the service life of the system.

[0122] Hereinafter, the heating elements of the aerosol supply system of the present invention and the structure of the aerosol supply system will be introduced in detail by way of specific embodiments.

[0123] Embodiment 1

[0124] Figure 1 is a three-dimensional structure diagram of the heating element of the aerosol supply system provided by the embodiment of the present invention. Refer to Figure 1 As shown, the heating element 341 includes a heating main body 3410 for generating aerosol and extension parts 3412, 3413 connected to the heating main body 3410. The heating main body 3410 is configured to heat the aerosol generating material in the system to generate aerosol. The extension parts 3412, 3413 are configured to be electrically connected to the power supply electrodes of the system to supply power to the heating main body 3410. The resistance of the heating element 341 is mainly composed of the heating main body 3410 and the extension parts 3412, 3413. Although the extension parts 3412 and 3413 generate heat when energized, their main function is electrical connection rather than heating the aerosol generating material. Therefore, in the embodiments of the present invention, the resistance of the extension parts 3412, 3413 is used as the ineffective heating resistance of the heating element 341, the area occupied by them is used as the ineffective heating area of the heating element 341, and the energy generated by them is used as the ineffective energy of the heating element 341. The heating main body 3410 is used to provide the energy required to heat the aerosol generating material. In the embodiments of the present invention, the resistance of the heating main body 3410 is used as the effective heating resistance of the heating element 341, the area enclosed by the heating main body 3410 is used as the effective heating area of the heating element 341, the surface area of the resistance of the heating main body 3410 is used as the effective atomization surface area of the heating element 341, and the energy density obtained by the heating main body 3410 is used as the energy density obtained by the heating element 341.

[0125] It should be noted that the energy density of the heating element in the embodiments of the present invention refers to the energy that can be provided to the aerosol-forming material per unit area of the oil guide body in the corresponding area through the generated heat on the enclosed area enclosed by the heating element. The greater the energy density of the heating element, the higher the temperature of the corresponding aerosol-forming material can be heated to, the more aerosol is generated, and of course, the more carbon deposition is generated. In the present invention, heating elements with corresponding energy densities can be specifically designed according to the requirements of various atomization modes. For example, for e-liquids with high carbon deposition, heating elements with low energy density are used to reduce the temperature reached by heating the e-liquid, thereby reducing carbon deposition. Another example is that for e-liquids that require high power to be atomized, heating elements with high energy density are used to achieve a better atomization state.

[0126] The high or low energy density of a component is determined by the power and area that the component can obtain. As mentioned above, the energy density of the heating element in the present invention actually refers to the energy density of the heating body. Therefore, in addition to the power and area obtained by the heating element as a whole, the energy density of the heating element is also related to the effective heating resistance, effective atomization surface area, and effective heating area corresponding to its heating body. The magnitude of the power is related to the supply power and the setting of the resistance. Therefore, the energy density of the heating element is related to the external supply power and the heating element's own parameters related to various resistance parameters, atomization surface area parameters, and heating area parameters. In the embodiments of the present invention, the energy density of the heating element can be made different by configuring at least one of the external supply power of the heating element and its own resistance parameters, atomization surface area, and heating area parameters.

[0127] In one embodiment of the present invention, different resistance parameters of the heating element are configured to achieve different energy density settings. Different resistance parameters may specifically include different resistances of the heating element and / or different effective heating resistances and / or different ratios of the effective heating resistances. Different resistance parameters may result in corresponding different powers. Under the same supply power and the same or reasonably set area parameters, different resistance parameters can achieve different energy density settings.

[0128] For example, when the resistances of the heating elements are set differently, under the same other conditions (the same supply power, the same area of each corresponding part, and the same ratio of the resistances of each corresponding part), the atomization powers obtained by the heating elements are different, and the atomization powers of the corresponding heating body parts are different, thereby resulting in different energy densities of the heating elements.

[0129] If the effective heating resistances of the heating elements are set differently, under the same other conditions (the same power supply, the same overall resistance of the heating element, and the same area of the corresponding parts), the atomization power obtained by the heating elements is the same, while the atomization powers of the corresponding main heating parts are different, thus resulting in different energy densities of the heating elements. It can be understood that different energy densities can also be achieved when other conditions are not exactly the same. For example, if one heating element has a large effective heating resistance and a small effective atomization surface area, and another heating element has a small effective heating resistance and a large effective atomization surface area, under the same other conditions, the energy density of the former is greater than that of the latter.

[0130] If the proportions of the effective heating resistances are set differently, under the same other conditions (the same power supply, the same overall resistance, and the same area of the corresponding parts), the atomization power obtained by the heating elements is the same, while the atomization powers of the corresponding main heating parts are different, thus resulting in different energy densities of the main heating parts.

[0131] In an embodiment of the present invention, the heating element includes a heating wire. The different resistance parameters of the above-mentioned heating element can be specifically achieved by different lengths of the heating wire and / or different resistivity of the heating wire and / or different cross-sectional areas of the heating wire.

[0132] Under the premise of the same other conditions, the longer the length of the heating wire or the smaller the cross-sectional area of the heating wire or the higher the resistivity of the heating wire, the greater the resistance. In the embodiments of the present invention, different resistance parameters of different heating elements can be set by at least one of these parameters.

[0133] In an embodiment of the present invention, the main heating part of the heating element includes a main heating wire that constitutes the effective heating resistance; the heating element includes four second parameters: the cross-sectional area of the main heating wire, the length of the main heating wire, the resistivity of the main heating part, and the resistivity of the extension part; when the resistance of the heating element is the same, the different proportions of the effective heating resistance of the heating element are configured by at least one different second parameter.

[0134] In one embodiment, it is possible to set the cross-sectional area of the main heating wire of the heating element with a high energy density to be smaller than the cross-sectional area of the main heating wire of the heating element with a low energy density. The smaller the cross-sectional area, under the same other conditions, the larger the effective heating resistance, so the proportion of the effective resistance is larger, the atomization power that can be obtained is higher, and thus the energy density is higher.

[0135] In one embodiment, the length of the heating wire of the heating body of the heating element with a high energy density can be set to be greater than the length of the heating wire of the heating body of the heating element with a low energy density. Under the same other conditions, when the length of the heating wire of the heating body is larger, correspondingly, the effective heating resistance and the proportion of the effective heating resistance of this heating element are larger, and the atomization power that can be obtained is higher, and thus the energy density is higher.

[0136] In one embodiment, the resistivity of the heating body of the heating element with a high energy density is higher than the resistivity of the heating body of the heating element with a low energy density. The higher the resistivity of the heating body, under the same other conditions, the larger the effective heating resistance, and thus the larger the proportion of the effective resistance.

[0137] In one embodiment, the resistivity of the extension part of the heating element with a high energy density is less than the resistivity of the extension part of the heating element with a low energy density. Under the same other conditions, the smaller the resistivity of the extension part, the smaller the ineffective heating resistance of the extension part, and thus the larger the proportion of the effective resistance.

[0138] In one embodiment, the material of the extension part of the heating element with a high energy density is nickel; and / or; the material of the heating body of the heating element with a high energy density is at least one of ferritic-aluminum, nickel-chromium, stainless steel and titanium alloy. In order to achieve a relatively large resistivity of the heating body and a relatively small resistivity of the extension part.

[0139] To achieve different resistivities, in the embodiments of the present invention, at least part of the structure of at least one extension part can be set as a first section body, and the resistivity of the first section body is less than the resistivity of the heating body. Through the setting of the first section body, the ineffective heating resistance can be reduced, and the proportion of the effective heating resistance can be increased. While realizing different energy density settings, the ineffective power consumption is reduced to reduce energy waste.

[0140] As Figures 1-4 shown, several setting methods of the first section body are provided. The extension part 3412 includes a fixing part 34121 and a pin 34122; the extension part 3413 includes a fixing part 34131 and a pin 34132. In the embodiments of the present invention, according to needs, part or all of one extension part, or part or all of two extension parts can be selected to form the first section body. In the following figure, the thinner part represents the first section body.

[0141] In one embodiment of the present invention, only the pin of one extension part of the heating element is formed into the first section body. The fixing part of this extension part and the whole of the other extension part are not the first section body.

[0142] As Figure 1As shown, only the pin 34122 of the extension part 3412 is formed into the first section body. The fixing part 34121 of the extension part 3412 and another extension part 3413 can be integrally formed with the heating main body 3410, providing a relatively good supporting effect on the heating main body 3410 and preventing the net-shaped heating main body 3410 from deforming. At this time, the material of the fixing part 34121 of the extension part 3412 is different from that of the pin 34122, and it is difficult to be integrally formed. The pin 34122, i.e., the first section body, can be connected to the fixing part 34121 by means of clamping, crimping or welding.

[0143] In an embodiment where the pin of the extension part forms the first section body while the fixing part does not form the first section body, the cross-sectional shapes of the fixing part and the first section body can be set to be different. For example, the cross-section of the fixing part is rectangular, while the first section body is circular, etc. The cross-sectional shape of the fixing part can be set from the perspective of facilitating integral formation with the heating main body and providing better support for the heating main body.

[0144] In an embodiment of the present invention, the pin and the fixing part of one extension part in the heating element are formed into the first section body. The other extension part as a whole is not the first section body. As Figure 2 shown, the fixing part 34121 and the pin 34122 of one extension part 3412 of the heating element 341 together form the first section body. The other extension part 3413 as a whole is not the first section body. Of course, in the present invention, it is also possible to select that the fixing part 34121 and the pin 34122 of the extension part 3412 together form the first section body. When the fixing part and the pin of one extension part together form the first section body, the two can be integrally formed without considering the connection and fixing problem. At this time, the fixing part can be connected to the heating main body 3410 by means of clamping, crimping or welding. Among them, the extension part that does not form the first section body can be integrally formed with the heating main body to provide better support for the heating main body and prevent the net-shaped heating main body from deforming.

[0145] Considering that in the heating element, the lengths of the pins of different extension parts may be different. As Figure 1 shown, the heating element 341 is in a flat plate shape, and at least one of the two extension parts 3412 and 3413 is in a semi-enclosing shape and is arranged on the outer periphery of the heating main body 3410 and surrounds the heating main body 3410. Preferably, both of the two extension parts 3412 and 3413 are in a semi-enclosing shape, arranged on the outer periphery of the heating main body 3410 and enclosing and defining the accommodating space of the heating main body 3410. As Figure 1 shown, the semi-enclosing shape is in an L shape. The first section body is formed as a part of the semi-enclosing shape.

[0146] In the above semi-enclosed structure, the length of the pin 34122 of the extension part 3412 is greater than the length of the pin 34132 of the extension part 3413. In an embodiment of the present invention, it is preferable that the pin 34122 of the extension part 3412 or the pin 34122 of the extension part 3412 and the fixing part 34121 form a first body, so as to increase the resistance value of the reduced ineffective resistance, and further increase the reduction amount of the ineffective power consumption. Of course, in the non-enclosed embodiment structure of the present invention, a longer pin can also be selected to form the first body.

[0147] In an embodiment of the present invention, the pins of the two extension parts in the heating element are formed into a first body. As Figure 3 shown, the pin 34122 of the extension part 3412 and the pin 34132 of the extension part 3413 of the heating element 341 form a first body. The fixing parts 34121 of the extension part 3412 and the fixing part 34131 of the extension part 3413 do not form a first body. At this time, the fixing parts of the two extension parts can be integrally formed with the heating main body, so as to provide better support for the heating main body from different directions and positions, and avoid the deformation of the mesh-shaped heating main body. Of course, in an alternative embodiment, the fixing part of one of the extension parts can also form a first body.

[0148] In an embodiment of the present invention, the pins and fixing parts of the two extension parts in the heating element are both formed into a first body. As Figure 4 shown, the pin 34122 and the fixing part 34121 of the extension part 3412, and the pin 34132 and the fixing part 34131 of the extension part 3413 of the heating element 341 both form a first body. Based on this, the ineffective resistance value can be reduced to the maximum extent, and then the ineffective power consumption can be reduced.

[0149] It should be noted that when the heating main body is a mesh-shaped heating main body, the extension part also plays a role in supporting the heating main body. When setting the first body in the present invention, the balance between reducing the ineffective resistance and the supporting effect can be comprehensively considered. For example, by setting some extension parts as the first body, the remaining extension parts can maintain a better supporting effect. Of course, the present invention can also adopt other means to improve the supporting effect, and on this basis, set as many first bodies as possible to minimize the ineffective resistance and reduce the ineffective power consumption.

[0150] In an embodiment of the present invention, the above first body can be composed of a material with a single resistivity, so that the resistivity of each part of the first body is the same, which is convenient for preparing the first body in the process.

[0151] Of course, in an alternative embodiment, the first body can include at least two segmented bodies with different resistivities, and the resistivity of all the segmented bodies is lower than the resistivity of the heating main body.

[0152] In one embodiment of the present invention, the cross-section of the first section body is circular or rectangular.

[0153] In one embodiment of the present invention, the atomization surface areas of the heating elements are configured differently to achieve different energy density settings. The different atomization surface areas of the heating elements include at least one of the following parameters being different:

[0154] The effective atomization surface areas are different and / or the cross-sectional areas of the heating bodies are different and / or the unit surface areas of the heating bodies are different.

[0155] For example, when setting the effective atomization surface areas to be different, under the same other conditions (the atomization power obtained by the heating body is the same), with different effective atomization surface areas, the corresponding energy densities are different. The smaller the effective atomization surface area, the greater the energy density.

[0156] For example, when setting the cross-sectional areas of the heating bodies to be different to achieve different effective atomization surface areas, under the same other conditions (the length of the heating body and the atomization power obtained by the heating body are the same), the corresponding energy densities are different. The smaller the cross-sectional area, the smaller the effective atomization surface area, and the greater the energy density.

[0157] In one embodiment of the present invention, the heating element includes a heating wire. The different effective atomization surface areas of the heating element include the cross-sectional area of the heating wire being different and / or the length of the heating wire being different. Under the same other conditions, the larger the cross-sectional area of the heating wire and the longer the length of the heating wire, the larger the effective atomization surface area of the heating element.

[0158] In one embodiment of the present invention, the heating element includes a heating body heating wire that constitutes an effective heating resistance. The heating element includes two third parameters: the cross-sectional area of the heating body heating wire and the length of the heating body heating wire; the different effective atomization surface areas of the heating element are configured by at least one of the third parameters being different.

[0159] In one embodiment of the present invention, the cross-sectional area of the heating body heating wire of the heating element with a high energy density can be set to be smaller than that of the heating element with a low energy density. Under other conditions including the same resistance of each part, the smaller the cross-sectional area, the smaller the effective atomization surface area, and thus the energy density can be increased.

[0160] In another embodiment of the present invention, the length of the heating body heating wire of the heating element with a high energy density is smaller than that of the heating element with a low energy density. Under other conditions including the same resistance of each part, the longer the length, the larger the effective atomization surface area, and thus the energy density can be reduced. As Figure 1 In the structure shown, the length of the heating body heating wire can be adjusted by setting the number of different diamond-shaped mesh holes.

[0161] It should be noted that the above parameter settings need to be combined with the same or reasonable configuration of other parameters in order to finally achieve different energy densities.

[0162] In an embodiment of the present invention, the heating area parameters of the heating element are configured differently to achieve different energy density settings. Among them, the different heating area parameters of the heating element include different occupied heating areas of the heating element and / or different effective heating areas and / or different proportions of the effective heating area.

[0163] For example, when setting different occupied heating areas of the heating element, under the same other conditions (the atomization power obtained by the heating element is the same, and the proportion of the effective heating area is the same), at this time, the energy density of the heating element is different. The larger the heating area, the lower the energy density.

[0164] For example, when setting different effective heating areas occupied by the heating element, under the same other conditions (the atomization power obtained by the heating main body is the same), different effective heating areas correspond to different energy densities. The smaller the effective heating area, the greater the energy density.

[0165] When the heating element is Figure 1 the shown mesh structure, the size of the effective heating area can be changed by compressing or expanding the size of the middle mesh holes.

[0166] In a specific embodiment of the present invention, the resistances of different heating elements are the same. This means that under the same power supply, the atomization power of the heating element is the same. At this time, different energy densities can be achieved by adjusting the parameters of the heating main body part, such as the atomization power obtained by the heating main body and the area of the heating main body. Specifically, different energy density settings can be achieved by at least one of the three first parameters: the proportion of the effective resistance, the effective atomization surface area, and the effective heating area.

[0167] In an embodiment of the present invention, when the resistances of different heating elements are the same, the proportion of the effective heating resistance of the heating element with a high energy density is higher than that of the heating element with a low energy density. When the resistances of the heating elements are the same, under the same power supply, the current of the heating element is the same. A high proportion of the effective heating resistance means a high atomization power obtained by the heating main body. When the effective atomization area and the effective heating area of the heating element are the same, the corresponding energy density of the heating element is high. In an alternative embodiment, the effective atomization area and the effective heating area of the heating element with a high proportion of the effective heating resistance can be set to be smaller than those of the heating element with a low proportion of the effective heating resistance, or by comprehensively considering several factors such as the proportion of the effective heating resistance and the area, the energy density of the heating element with a high proportion of the effective heating resistance is high.

[0168] In an embodiment of the present invention, when the resistances of different heating elements are the same, the effective atomization surface area of the heating element with a high energy density is smaller than that of the heating element with a low energy density. When the resistances of the heating elements are the same, at the same power supply, the atomization power of the heating elements is the same. If the effective heating resistances are set to be the same and the effective heating areas are the same, then the heating element with a smaller effective atomization surface area has a higher energy density. In an alternative embodiment, the effective heating resistance of the heating element with a smaller effective atomization surface area is greater than that of the heating element with a larger effective atomization surface area, and the effective heating surface area is also smaller. Or, several factors such as the effective atomization surface area, the effective heating resistance, and the effective heating area can be comprehensively considered to make the heating element with a smaller effective atomization surface area have a high energy density.

[0169] In an embodiment of the present invention, when the resistances of different heating elements are the same, the effective heating area of the heating element with a high energy density is smaller than that of the heating element with a low energy density. When the resistances of the heating elements are the same, it means that at the same power supply, the atomization power obtained by the heating elements is the same. If the effective heating resistances are set to be the same and the effective atomization areas are the same, then the heating element with a smaller effective heating area has a higher energy density. In an alternative embodiment, the effective heating resistance of the heating element with a smaller effective heating area is greater than that of the heating element with a larger effective heating area, and the effective atomization area is also smaller. Or, several factors such as the effective heating area, the effective heating resistance, and the effective atomization surface area can be comprehensively considered to make the heating element with a smaller effective heating area have a high energy density.

[0170] In the embodiments of the present invention, the settings for increasing the energy density can be referred to as favorable settings, such as reducing the effective atomization surface area and increasing the proportion of the effective resistance. The settings for reducing the energy density can be referred to as unfavorable settings, such as increasing the effective atomization surface area and increasing the proportion of the ineffective heating resistance. To achieve different energy densities, in the embodiments of the present invention, one or more favorable settings can be adopted for one heating element, and one or more unfavorable settings can be adopted for another heating element. In an alternative embodiment, the heating element can also be adopted in a combination of partial favorable settings and partial unfavorable settings, as long as the final comprehensive design enables different heating elements to obtain different energy densities.

[0171] In the above embodiments of the present invention, by configuring the resistance parameters, atomization surface area parameters, and heating area parameters of the heating element, different energy density configurations of the heating element can be provided, thereby realizing the cooperation with different atomization modes of the system, achieving a better atomization state in different atomization modes, and improving the user experience. At the same time, through the better matching of different energy densities and atomization modes, problems such as carbon deposition and damage due to mismatch with the power supply can be reduced, and the service life of the system can be improved.

[0172] Embodiment 2

[0173] Based on the heating element provided in the first embodiment above, the second embodiment of the present invention provides an aerosol supply system. As Figure 5 shown, the aerosol supply system 300 has at least two atomization modes, and the aerosol supply system 300 receives aerosol-forming materials.

[0174] The aerosol supply system 300 includes at least two heating elements 341. Each heating element 341 corresponds to one atomization mode and is configured to heat the aerosol-forming materials in the aerosol supply system 300 in the corresponding atomization mode to generate aerosol. The energy densities of two heating elements 341 corresponding to different atomization modes are different.

[0175] A controller 343, configured to select at least one of the corresponding heating elements 341 for heating according to the received atomization mode selection instruction; for example, sending a first atomization mode instruction to one of the heating elements 341 and sending a second atomization mode instruction to the other heating element 341.

[0176] A power supply 342, configured to supply power to the heating element 341 under the control of the controller 343. The power supply can be one or more.

[0177] In one embodiment of the present invention, the set powers of the heating elements with different energy densities are the same. Although the powers are the same, the heating elements can achieve different energy densities through the settings of parameters such as area and effective heating resistance.

[0178] In another embodiment of the present invention, the set powers of the heating elements with different energy densities are different. Specifically, at least two atomization modes include at least two levels of set power; the heating element with a higher energy density corresponds to a higher level of set power, and the heating element with a lower energy density corresponds to a lower level of set power;

[0179] The controller is configured to select the heating element with a higher energy density for heating when receiving a selection instruction for a higher level of set power, and is configured to select the heating element with a lower energy density for heating when receiving a selection instruction for a lower level of set power.

[0180] By matching the power with the energy density, the heating element and the power atomization mode can reach the best matching state to achieve the best atomization state and improve the service life of the heating element.

[0181] In another embodiment of the present invention, the system includes three levels of set power, and the highest level of set power is the sum of the other two levels of set power; the controller is configured to select the two heating elements for heating when receiving a selection instruction for the highest level of set power. Through this embodiment, a higher power atomization mode can be added without increasing the heating elements.

[0182] Specifically, the heating element described above may be selected from the heating elements disclosed in Embodiment 1 of the present invention. For details here, reference may be made to the description of Embodiment 1, and the relevant content will not be elaborated here.

[0183] Embodiment 3

[0184] Embodiment 3 of the present invention provides a control method for an aerosol supply system, where the system includes at least two heating elements corresponding to different atomization modes; as Figure 6 shown, the method includes:

[0185] S21. Receive an atomization mode selection instruction;

[0186] S22. Select at least one of the corresponding heating elements for heating according to the atomization mode selection instruction; the energy densities corresponding to different heating elements are different.

[0187] In one embodiment of the present invention, the system is the aerosol supply system disclosed in Embodiment 2 above and has multiple heating elements disclosed in Embodiment 1 above.

[0188] In one embodiment of the present invention, the above atomization mode selection instruction may be generated according to an instruction input by a user or according to a signal monitored by a sensor. For example, an instruction input by a user is received through different buttons or an electronic interaction interface, or different gestures of the user are monitored by a sensor to generate a corresponding atomization mode selection instruction.
