[0002] In the e-cigarette industry, aerosol supply systems are configured to generate aerosols from an aerosol-generating matrix (e.g., containing tobacco or leaf substrate) for users to inhale. The generation of aerosols from the aerosol-generating matrix requires heating technology. Existing aerosol supply systems typically employ resistance heating technology. The resistance heating structure is usually evenly arranged within the heating element, heating the aerosol-generating material when energized. In practical use, the heating element needs multiple heating zones at different temperatures to meet varying heating requirements. However, existing resistance heating structures can only provide uniform heating and cannot meet the different temperature control requirements of multiple heating zones. Summary of the Invention

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.

[0093] A sensor is a material that can be heated by being penetrated by a changing magnetic field (e.g., 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.

[0094] 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.

[0095] 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.

[0096] This disclosure relates to aerosol supply systems (which may also be referred to as vapor supply 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 supply systems / devices and electronic aerosol supply 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.

[0097] Aerosol supply systems (electronic cigarettes) typically (though not always) comprise modular components, including reusable device parts and replaceable (disposable / consumable) cartridge components. Typically, the replaceable cartridge component 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 source) 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.

[0098] 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 so-called box-shaped patterns that are typically box-shaped. More generally, it will be understood that some embodiments of this disclosure are based on an aerosol delivery system operationally 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.

[0099] As described in the background section, heating components require multiple heating zones with different temperatures in practical use to meet varying heating needs. For example, the top of the heating element needs a higher temperature to fully heat the aerosol-generating material, while the bottom needs a lower temperature to reduce heat transfer to the outside in the installation area in contact with the system, thus minimizing disruption to normal system operation. Based on this, the present invention proposes a heating component for an aerosol supply system to address the technical problem of how to meet the different temperature control requirements of multiple heating zones within the heating component.

[0100] See appendix Figure 1 , Figure 1 A heating component 100 for an aerosol supply system is shown. The heating component 100 is configured to at least partially insert into the aerosol generating material for heating. The heating component 100 includes a housing 101 and an electromagnetic induction heating structure located within the housing 101. The electromagnetic induction heating structure includes an induction coil 102 and a sensor layer 103, the sensor layer 103 being configured to sense and heat upon contact with a changing magnetic field generated by the induction coil 102. The present invention aims to achieve heating of the corresponding electromagnetic induction area by incorporating an electromagnetic induction heating structure in the heating component. The sensor layer senses the changing magnetic field generated by the induction coil and heats the aerosol generating material. Simultaneously, the induction coil itself has a resistance heating function, allowing the location with the sensor layer to experience both electromagnetic induction heating and resistance heating simultaneously. The sensor layer can be positioned arbitrarily to increase the heating temperature at the corresponding location, thereby achieving temperature control over a wider area.

[0101] It should be noted that, in order to illustrate this technical solution, Figure 1 This is merely a partial structural diagram of the heating component 100 and is not intended to convey the specific locations and fixed structural patterns of various components. For example, the sensor layer 103 may not be enclosed by the induction coil 102; it can simply be placed at a location where it can sense the magnetic field of the induction coil 102. The sensor layer 103 can be located anywhere within the housing 101 where it needs to be heated. Furthermore, the length of the induction coil 102 can be determined based on the length of the desired heating area and is not limited to the shape, position, and length shown in the diagram.

[0102] In one implementation, such as Figure 2 As shown, the induction coil 102 is sleeved outside the sensor layer 103, realizing the superposition of electromagnetic induction heating and resistance heating in the area where the sensor layer 103 is provided, thereby increasing the heating temperature of the area. At the same time, the sleeved method makes it easier to install and use.

[0103] In one implementation, such as Figure 3As shown, a resistance heating structure is also provided inside the housing 101. The resistance heating structure includes a heating resistor 104, which is configured to heat when energized. The induction coil 103 and the heating resistor 104 can be two separate parts, or they can be two separate structures within the same component. For example, in... Figure 3 In this design, a portion of the induction coil 102 is straightened to serve as a heating resistor 104. This can also be understood as the heating resistor 104 being a separately configured power supply line with resistance. In this case, region A at the sensor layer 103 utilizes a combination of electromagnetic induction heating and resistance heating, while region B, corresponding to the heating resistor 104, uses only resistance heating. The temperature in region A will be higher than the heating temperature in region B, thus achieving different temperature control for different zones. It is important to understand that... Figure 3 This is not a limitation on the heating area of ​​the heating component 100. Depending on actual needs, heating control can be achieved in different areas by combining or selecting one of electromagnetic induction heating structure and resistance heating structure.

[0104] In one implementation, such as Figure 4 As shown, both the induction coil 102 and the heating resistor 104 are part of the coil. The induction coil 102 is the first part of the coil, and the heating resistor 104 is the second part. Region A corresponding to the first part uses a combination of electromagnetic induction heating and resistance heating, while region B corresponding to the second part uses resistance heating alone. The temperature in region A will be higher than the heating temperature in region B, achieving different temperatures for different zones. Using the same coil to achieve multiple zones is simpler in process and easier to set up compared to setting them separately. Furthermore, the sensor layer 103 coincides with the radial projection of the first part; the radial projection of the sensor layer 103 is offset from that of the second part. The position of the sensor layer 103 distinguishes the heating method of the region. For example, region A with the sensor layer 103 uses a combination of electromagnetic induction heating and resistance heating, while region B uses only resistance heating. It is important to understand that… Figure 4 It is not a limitation on the position and length of the sensor layer 103. The sensor layer 103 can extend from one end of the coil to the other in the axial direction. If there is a changing current in the coil, the sensor layer 103 can sense the changing magnetic field, and the corresponding area will be heated by electromagnetic induction; otherwise, it will be heated by resistance.

[0105] In one implementation, such as Figure 5As shown, the heating element 100 has a fixed end 200 for fixing in the aerosol supply system, and a free end 300 opposite to the fixed end 200. The heating element 100 is configured such that the portion near the free end 300 has a higher heating efficiency than the portion near the fixed end 200. Since the fixed end 200 is in contact with the aerosol supply system, this portion requires a lower temperature to prevent heat transfer to other components of the system and affecting normal system operation. Furthermore, the heating efficiency of the heating element 100 can increase from the fixed end 200 to the free end 300, which can be a gradual decrease, a gradient decrease, or a combination of both, as long as the temperature decreases from the free end 300 to the fixed end 200.

[0106] Based on the heating requirements and heating structure at both ends of the heating component 100, the temperature drop from the free end 300 to the fixed end 200 can be achieved through the following methods:

[0107] If only a resistance heating structure is provided in the heating component 100, the cross-sectional area of ​​the heating resistor 104 decreases along the direction from the fixed end 200 to the free end 300. The smaller the cross-sectional area, the smaller the resistance and the higher the heating efficiency. Therefore, the heating efficiency of the free end 300 is higher than that of the part near the fixed end 200. Furthermore, the heating resistor 104 extends from the fixed end 200 to the free end 300 in the length direction. That is, the entire heating component 100 adopts resistance heating and can meet the temperature changes in different areas.

[0108] If only an electromagnetic induction heating structure is provided in the heating component 100, the pitch of the induction coil 102 decreases along the direction from the fixed end 200 to the free end 300. The smaller the pitch, the stronger the magnetic field change sensed by the sensor layer 103, and the higher the heating efficiency. Therefore, the heating efficiency of the free end 300 is higher than that of the part near the fixed end 200. Furthermore, the induction coil 102 extends from the fixed end 200 to the free end 300 in the length direction. That is, the heating component 100 as a whole adopts electromagnetic induction heating and can meet the temperature changes in different areas.

[0109] If both electromagnetic induction heating structure and resistance heating structure are provided within the heating element 100, such as Figure 5 As shown, the heating component 100 may include a first heating zone C and a second heating zone D. The first heating zone C is closer to the free end 300 than the second heating zone D. An electromagnetic induction heating structure and a resistance heating structure are provided in the first heating zone C, and one of the electromagnetic induction heating structure or the resistance heating structure is provided in the second heating zone D. This can achieve a higher heating efficiency for the free end 300 than for the part closer to the fixed end 200. The specific electromagnetic induction heating structure and resistance heating structure are described in the above description of the induction coil and heating resistor settings. Repeated descriptions will not be repeated.

[0110] In one implementation, such as Figure 1 As shown, the heating element 100 also includes a coil support 105, which supports the induction coil 102 and the sensor layer 103. In this invention, the coil support 105 can be a ceramic tube, or it can be made of other high-temperature resistant, non-conductive materials. Furthermore, the outer shell 101 is a metal shell, which can quickly conduct the heat generated by the electromagnetic induction heating structure and the resistance heating structure to the aerosol generating material. The outer shell 101 also has a filler 107 for filling the internal gaps of the heating element 100. The filler 107 is an insulating, high-temperature resistant material, and is filled in a liquid state at the end of the assembly of the heating element 100.

[0111] In one embodiment, the receptor layer 103 may be a metal foil or made of one of iron, cobalt, nickel, gadolinium, erbium, or an alloy thereof. The thickness of the receptor layer 103 is less than 0.5 mm, and the Curie temperature is below 1100°C.

[0112] In another implementation, such as Figure 6 As shown, a groove 1051 is provided on the outer surface of the coil bracket 105, and the sensor layer 103 is located in the groove 1051, which facilitates the installation of the sensor layer 103. It should be understood that the position of the groove 1051 can be set according to the needs of the heating area, and the specific position is not limited.

[0113] In another implementation, such as Figure 7 As shown, the coil support 105 is cylindrical, and the sensor layer 103 is coated on the outer circumferential surface of the coil support 105 and set on the coil support 105 by printing. The printing position can be provided with a groove 1051, or it can be printed directly without a groove 1051, which is simpler in terms of manufacturing process.

[0114] In one implementation, such as Figure 1 As shown, the column of the coil support 105 has a hollow structure, and the hollow structure is used for the passage of the energized wire 106. The energized wire 106 connects the induction coil 102 and / or the heating resistor 104 so that when energized, the induction coil 102 generates a changing magnetic field and the heating resistor 104 is energized and heated.

[0115] Based on the above implementation, when the system is powered on, current flows from the energized wire 106 to the induction coil 102 surrounding the coil support 105. The induction coil 102 itself generates heat through resistance heating and conducts it to the outer shell 101. Simultaneously, when the current flows through the induction coil 102, a magnetic field is generated, acting on the sensor layer 103. Due to eddy currents, the sensor layer 103 generates heat in the corresponding area, which is conducted to the outer shell 101. The area with the sensor layer 103 has a higher temperature than either electromagnetic induction heating or resistance heating due to the superposition of electromagnetic induction heating and resistance heating. Furthermore, even if heat from the bottom area of ​​the heating component 100 is conducted to the top area as the aerosol flows upward, an electromagnetic heating structure can be provided in the middle area to achieve the same temperature as the top area. Specifically, this can be configured according to requirements to achieve different temperature settings in multiple areas of the heating component.

[0116] Furthermore, such as Figure 8 As shown, the present invention provides an aerosol supply system, the system comprising:

[0117] Cavity 500 for receiving aerosol-generating materials;

[0118] The heating component 100 as described above.

[0119] In one embodiment, the system further includes a mounting base 400 for mounting the heating component 100 in the system. One end of the heating component 100 is a pointed tip, i.e., in the form of a heating needle, to facilitate the insertion of aerosol generating materials. The temperature of the pointed tip of the heating component 100 is higher than that of the end near the mounting base 400.
