Description

Technical Field

[0001] This application relates to the field of atomization technology, and more specifically, to a heating component, a heating structure, and an aerosol generating device. Background Technology

[0002] In the field of atomization technology, aerosol generating devices heat and atomize an aerosol generating matrix through a heating structure, thereby causing the matrix to generate aerosols. Specifically, the heating components in the aerosol generating device radiate energy to the aerosol generating matrix to produce aerosols. Currently, some aerosol generating devices have multiple heating elements along their length. The heat generated by these elements can interfere with each other, resulting in temperature crosstalk. This makes it impossible to precisely control the temperature of different sections of the aerosol generating matrix, leading to slow heating rates, small initial aerosol volume, poor consistency in taste between subsequent aerosols, and high energy consumption.

[0055] In the field of atomization technology, aerosol generating devices heat and atomize an aerosol generating matrix through a heating structure, thereby causing the aerosol generating matrix to generate aerosols. Specifically, the heating component in the aerosol generating device radiates energy to the aerosol generating matrix to produce aerosols. Currently, some aerosol generating devices have multiple heating elements arranged along their length. The heat generated by each heating element interferes with each other, resulting in a temperature crosstalk problem. This makes it impossible to accurately control the temperature of different sections of the aerosol generating matrix, leading to slow heating rate, small initial aerosol volume, poor consistency in taste of subsequent aerosols, and high energy consumption. To solve this problem, this application provides a heating component 30 ( Figure 1 and Figure 2 (as shown), heating structure 100 ( Figure 5 and Figure 6 (as shown) and aerosol generating device 1000 ( Figure 7 (As shown).

[0056] Please refer to this as well. Figure 1 and Figure 2In a first aspect, this application provides a heating assembly 30. The heating assembly 30 includes at least two heating units 310 and a separator 32. The at least two heating units 310 are arranged sequentially at intervals along the length direction Z of the heating assembly 30. The separator 32 includes a first end 321 and a second end 323, the first end 321 and the second end 323 of the separator being located at opposite ends of the separator 32 along the length direction Z. A separator 32 is disposed between two adjacent heating units 310, the first end 321 of the separator being connected to one of the two adjacent heating units 310, and the second end 323 of the separator being connected to the other of the two adjacent heating units 310. The at least two heating units 310 and the separator 32 together form an atomizing cavity 311 open at both ends, the atomizing cavity 311 being configured to contain an aerosol generating matrix 20. Figure 5 As shown, the heating unit 310 is configured to heat the aerosol generating matrix 20 in the atomization chamber 311. The heating energy of the heating unit 310 can be controlled individually, and the separator 32 is configured to prevent heat transfer between adjacent heating units 310.

[0057] Specifically, in the above embodiments, the aerosol generating device 1000 is an apparatus that loads the aerosol generating matrix 20 and heats it to generate aerosols. The aerosol generating matrix 20 can be pulverized into fine particles by heating or ultrasonic vibration and mixed with air to form an aerosol. The aerosol can be visible or invisible and may include vapor (e.g., fine particulate matter in a gaseous state, which is typically liquid or solid at room temperature) as well as liquid droplets of gas and condensed vapor. The aerosol generating matrix 20 can be in a liquid state or a solid state (including fully solid and semi-solid). In the embodiments of this application, the aerosol generating matrix 20 is a long strip solid, which is inserted into the heating element 30 of the aerosol generating device 1000 during use.

[0058] The heating element 30 is used in an aerosol generating device 1000. The function of the heating element 30 is to heat the aerosol generating matrix 20 loaded in the aerosol generating device 1000 to generate aerosols. Please refer to... Figure 6In the direction in which the aerosol generating matrix 20 is inserted into the aerosol generating device 1000, the aerosol generating matrix 20 sequentially includes a mouthpiece section 23, a medium section 21, and a plug section 25. The mouthpiece section 23, the medium section 21, and the plug section 25 each have different dielectric constants. The mouthpiece section 23 is the part of the aerosol generating matrix 20 that comes into direct contact with the user's mouth and is responsible for outputting aerosols. The mouthpiece section 23 can be further subdivided into a cooling section 233 and a filtering section 231. The filtering section 231 is closer to the user's mouth and is used to absorb or block condensate from entering the mouth; the cooling section 233 is used to isolate high temperatures, cool the aerosols, and prevent burns to the mouth. The medium section 21 is the part of the aerosol generating matrix 20 that carries the matrix components capable of generating aerosols. The plug section 25 is the end of the aerosol generating matrix 20 that seals the medium section 21, preventing matrix leakage and fixing the internal structure.

[0059] The heating element 30 can employ different heating methods to heat the aerosol generating matrix 20, and correspondingly, the heating element 30 includes different structures. In some embodiments, when the heating element 30 uses electromagnetic waves to heat the aerosol generating matrix 20, the heating element 30 includes an electromagnetic coil that can radiate electromagnetic waves to heat the aerosol generating matrix 20 and generate aerosols. In other embodiments, when the heating element 30 uses microwaves to heat the aerosol generating matrix 20, the heating element 30 includes a microwave generator that can radiate microwaves to heat the aerosol generating matrix 20 and generate aerosols. In still other embodiments, when the heating element 30 uses lasers to heat the aerosol generating matrix 20, the heating element 30 includes a laser emitter that can emit laser light to heat the aerosol generating matrix 20 and generate aerosols. In some embodiments, when the heating element 30 uses infrared light to heat the aerosol generating matrix 20, the heating element 30 includes a heating body 31, a heating element 33, and an infrared radiation layer 35. The heat generated by the heating element 33 causes the infrared radiation layer 35 to emit infrared light, thereby heating the aerosol generating matrix 20 to generate aerosol. This application uses the heating element 30 using infrared light to heat the aerosol generating matrix 20 as an example.

[0060] Heating unit 310 is the smallest unit in heating assembly 30 used to generate heat. The number of heating units 310 is at least two, but can also be three, four, five, or more, etc., without limitation. Along the length direction Z of heating assembly 30 (hereinafter referred to as length direction Z), the heating units 310 are arranged sequentially, with adjacent heating units 310 spaced apart. A separator 32 in heating assembly 30 is used to separate the heating units 310 to avoid mutual interference caused by heat transfer between adjacent heating units 310. The separator 32 includes a first end 321 and a second end 323, located on opposite sides of the separator 32 along the length direction Z. The separator 32 is disposed between adjacent heating units 310, with the first end 321 connected to one of the adjacent heating units 310 and the second end 323 connected to the other. The partition 32 and the heating unit 310 can be connected by abutment or by fixation. When the partition 32 and the heating unit 310 are fixedly connected, the connection can be either detachable or non-detachable. Detachable connections include, but are not limited to, one or more combinations of abutment, screw connection, and snap-fit ​​connection. Non-detachable connections include, but are not limited to, one or more combinations of gluing, welding, and sintering. This definition will be used for both detachable and non-detachable connections in the future.

[0061] At this time, at least two heating units 310 and the partition 32 are alternately arranged. Both the heating units 310 and the partition 32 are hollow structures. Therefore, the at least two heating units 310 and the partition 32 together form a space structure open at both ends, namely the atomizing chamber 311. The atomizing chamber 311 is used to contain the aerosol generating matrix 20, and the atomizing chamber 311 can allow gas to flow in and out. After the aerosol generating matrix 20 is loaded into the atomizing chamber 311, it can be heated by the heating units 310 to generate aerosol. In the heating assembly 30 of this application, at least two heating units 310 generate heating energy to heat the medium section 21 of the aerosol generating matrix 20. In order to accurately and controllably heat the medium section 21, each heating unit 310 is configured to be individually controlled to generate a certain amount of heating energy, so that at least a portion of the medium section 21 can be targeted and controlled for heating. Meanwhile, the separator 32 can prevent heat transfer between adjacent heating units 310. Therefore, when each heating unit 310 heats at least a portion of the medium section 21 opposite to it, the medium is less affected by the heating energy from other heating units 310, and each part of the medium section 21 can be precisely and controllably heated by its corresponding heating unit 310. In addition, the separator 32 can also seal the gaps between the heating units 310, preventing aerosol leakage to the outside of the heating element 31, preventing leaked aerosol from affecting the normal operation of other components, and extending the service life of the aerosol generating device 1000.

[0062] In the heating component 30 of this application, at least two heating units 310 and a separator 32 are alternately distributed along the length direction Z of the heating component 30, and together form an atomization chamber 311 open at both ends. When the aerosol generating matrix 20 is housed in the atomization chamber 311, the heating energy of each heating unit 310 can be individually controlled to perform zone heating of the aerosol generating matrix 20. At this time, the separator 32 can prevent the heat transfer between adjacent heating units 310, and there will be no cross-temperature problem in the zone heating process of the aerosol generating matrix 20. The heating component 30 can accurately control the temperature of each section of the aerosol generating matrix 20, resulting in fast heating rate, sufficient aerosol quantity in the first puff, high consistency of aerosol taste in each puff, and low energy consumption.

[0063] Please refer to Figure 1 and Figure 2In some embodiments, the heating unit 310 includes a heating element 31, a heating component 33, and an infrared radiation layer 35. The sidewalls of the heating element 31 form a sub-atomizing cavity 3113 open at both ends. The multiple sub-atomizing cavities 3113 of the multiple heating units 310 are interconnected and jointly used to form the atomizing cavity 311. The heating component 33 is disposed on the outer sidewall of the heating element 31 and surrounds the sub-atomizing cavity 3113. The heating component 33 is configured to generate heat when energized, and the energization control on the heating component 33 of each heating unit 310 is independent. The infrared radiation layer 35 is disposed on the sidewall of the heating element 31, and at least a portion of the heat generated by the heating component 33 is transferred to the infrared radiation layer 35, so that the infrared radiation layer 35 radiates infrared light to heat the aerosol generating matrix 20 in the corresponding sub-atomizing cavity 3113.

[0064] Specifically, the heating element 31 is a structure for accommodating at least a portion of the aerosol generating matrix 20, specifically, the heating element 31 is used to accommodate at least a portion of the medium segment 21 of the aerosol generating matrix 20. The heating element 31 has an open structure at both ends, and the structure enclosed by the sidewalls of the heating element 31 is the sub-atomizing cavity 3113, which is part of the atomizing cavity 311. The sub-atomizing cavity 3113 is also a spatial structure with open ends, so that at least a portion of the aerosol generating matrix 20 (specifically, at least a portion of the medium segment 21) extends into the sub-atomizing cavity 3113. In the length direction Z, multiple heating units 310 enclose multiple sub-atomizing cavities 3113, which are distributed sequentially, spaced apart from each other, and interconnected through the hollow cavity of the separator 32. At this time, each sub-atomizing cavity 3113 and the hollow cavity enclosed by the separator 32 are used together to form the atomizing cavity 311.

[0065] The heating element 33 is a component in the heating assembly 30 that generates and transfers heat energy. The heating element 33 includes, but is not limited to, heating circuits, heating films, heating sheets, heating wires, and heating meshes. The heating element 33 can be made of at least one of the following materials with appropriate impedance: metallic materials, metal alloys, graphite, carbon, conductive ceramics, tin-antimony oxide, other ceramic materials, and composite materials of metallic materials. The metallic materials include, but are not limited to, at least one of nickel, cobalt, zirconium, and titanium. The metal alloys include, but are not limited to, at least one of nickel alloys, cobalt alloys, zirconium alloys, titanium alloys, nickel-chromium alloys, nickel-iron alloys, iron-chromium alloys, iron-chromium-aluminum alloys, titanium alloys, or iron-manganese-aluminum based alloys.

[0066] The heating element 33 is disposed around the outer sidewall of the heating body 31 to fully heat the heating body 31, and the heating body 31 is disposed around the sub-atomizing cavity 3113. When energized, the heating element 33 generates heat and transfers it to the structure it contacts and radiates it to at least a portion of the space surrounding the heating element 33. In each heating unit 310 of this application, the energization control of the heating element 33 is independent of each other; any one heating element 33 can be configured to be energized or de-energized without interference from other heating elements 33. Similarly, whether the heating element 33 generates heat and the amount of heat generated are also independent of each other.

[0067] The infrared radiation layer 35 is a structure that can radiate infrared light when excited by heat. The material of the infrared radiation layer 35 may include, but is not limited to, chromium oxide, zirconium oxide, iron oxide, and graphene. The infrared radiation layer 35 is located on the side wall of the heating element 31. When the heating element 33 is energized and generates heat, at least a portion of the heat generated by the heating element 33 is transferred to the infrared radiation layer 35. The infrared radiation layer 35 receives the heat and radiates infrared light. The infrared light, through its energy, heats at least a portion of the medium segment 21 of the aerosol generation matrix 20 in the corresponding sub-atomization cavity 3113 to generate aerosol. The heat provided by the heating element 33 to the infrared radiation layer 35 includes heat directly transferred from the heating element 33 to the infrared radiation layer 35 and heat generated by the heating element 33 indirectly transferred to the infrared radiation layer 35 through other structures (such as the heating element 31). The power-on control of each heating element 33 is independent of each other, so the intensity of the infrared light generated by each infrared radiation layer 35 is also independent of each other. Correspondingly, the degree of heating of the medium section 21 is independent of each other, making the aerosol generation process more flexible and the generated aerosol has a better taste.

[0068] Therefore, during the process where the heat generated by the heating element 33 is transferred to the infrared radiation layer 35 to heat the aerosol generation matrix 20 by radiating infrared light, the infrared light generated by the infrared radiation layer 35 can uniformly heat at least a portion of the corresponding medium segment 21. The intensity of the infrared light generated by each infrared radiation layer 35 is also independent of each other, and the degree to which the corresponding medium segment 21 is heated is also independent of each other. The heating process of the aerosol generation matrix 20 can be flexibly and precisely controlled, and the generated aerosol has a better taste.

[0069] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments, among the multiple heating elements 33 of the multiple heating units 310, all heating elements 33 have the same parameters, including at least one of pattern shape, extension length, width, area and heat flux density.

[0070] In the above embodiments, the parameters of the heating element 33 include at least one of the following: the pattern shape of the heating element 33, the extension length of the heating element 33, the width of the heating element 33, the area of ​​the heating element 33, and the heat flux density of the heating element 33. The parameters of the heating element 33 directly affect the total amount and distribution of heat generated by the heating element 33. Specifically, the pattern shape affects the heat distribution generated by the heating element 33, thereby affecting the distribution of heat received by the infrared radiation layer 35 and the infrared light it generates, and consequently affecting the heating of the corresponding medium segment 21 by the heating unit 310. The pattern shape of the heating element 33 can be linear, polygonal, or curved, etc. The extension length is defined as the length of the heating element 33 when its central axis is stretched into a straight line, such as... Figure 3 The length of the central axis M in the diagram. Given a fixed pattern shape, the extension length determines the angular range (in terms of angle) of the heating element 33 surrounding the atomizing cavity 311 (sub-atomizing cavity 3113). Figure 2 From a top-down viewpoint (and considering the sub-atomizing cavity 3113 as circular), the longer the extension length, the larger the angle range of the heating element 33 around the atomizing cavity 311 (sub-atomizing cavity 3113). With the same heating power of the heating element 33, the heating element 334 transfers more and more heat to the infrared radiation layer 35 more evenly. The width W of the heating element 33 determines the area where the heating element 33 generates heat. The wider the width, the larger the area where the heating element 33 can generate heat, and the more heat is generated with the same heating power. The area is determined by the pattern shape, extension length, and width. The area determines the range of the heating element 33 around the atomizing cavity 311 (sub-atomizing cavity 3113). The larger the area, the larger the range of the heating element 33 around the atomizing cavity 311 (sub-atomizing cavity 3113). With the same heating power of the heating element 33, the heating element 334 transfers more and more heat to the infrared radiation layer 35 more evenly. Heat flux density represents the amount of heat transferred by the heating element 33 per unit area. The greater the heat flux density of the heating element 33, the more heat the heating element 334 transfers to the infrared radiation layer 35 when the area of ​​the heating element 33 is the same.

[0071] Please use Figure 3 For example, there are three heating units 310 and three heating elements 33. In this case, the parameters of the three heating elements 33 are completely identical; that is, the three heating elements 33 are completely identical. Therefore, when the three heating elements 33 are in the same energized state, the heat distribution generated by the three heating elements 33 and the heat radiated to the corresponding infrared radiation layer 35 per unit time are the same. Therefore, controlling the heating elements 33 to flexibly heat the aerosol generating matrix 20 is relatively simple; only different energized states need to be set for each heating element 33. The control program is relatively simple, and the engineering difficulty of the aerosol generating device 1000 is low.

[0072] Please refer to Figure 1 , Figure 2 and Figure 4 In some embodiments, among the multiple heating elements 33 of the multiple heating units 310, at least some parameters of at least one heating element 33 are different from the parameters corresponding to the other heating elements 33.

[0073] Specifically, "at least some parameters of at least one heating element 33 are different from the parameters corresponding to the other heating elements 33" includes, but is not limited to, any of the following examples: In one example, the pattern shape of one heating element 33 is different from the other heating elements 33, while the extension length, width, area, and heat flux density of the heating element 33 are the same as the other heating elements 33. In another example, the pattern shape and extension length of one heating element 33 are different from the other heating elements 33, while the width, area, and heat flux density of the heating element 33 are the same as the other heating elements 33. In yet another example, the pattern shape of the first heating element 33 and the pattern shape of the second heating element 33 are different from those of the other heating elements 33, while the extension length, width, area, and heat flux density of all heating elements 33 are the same. In yet another example, the pattern shape of the first heating element 33 is different from the other heating elements 33 (including the second heating element 33), the extension length of the second heating element 33 is different from the other heating elements 33 (including the first heating element 33), while the width, area, and heat flux density of all heating elements 33 are the same. At this time, by controlling the energizing state of each heating element 33, the heating component 30 can achieve a more complex combination of heating methods, making the heating of the aerosol generation matrix 20 more flexible and diverse.

[0074] Please refer to Figure 1 and Figure 2 In some embodiments, along the length direction Z, the heating element 30 includes a first end 301 and a second end 303 opposite to each other. The heating unit 310 includes an upper heating unit 3101 and a lower heating unit 3103. The upper heating unit 3101 is closest to the second end 303 of the heating element, and the lower heating unit 3103 is closest to the first end 301 of the heating element. The upper heating unit 3101 includes an upper heating body 312 and an upper heating element 332 disposed on the upper heating body 312. The upper heating body 312 forms an upper sub-atomization cavity 31131. The upper heating element 332 is configured to be energized to control the heat distribution in the upper sub-atomization cavity 31131. The lower heating unit 3103 includes a lower heating body 314 and a lower heating element 334 disposed on the lower heating body 314. The lower heating body 314 forms a lower sub-atomization cavity 31133. The lower heating element 334 is configured to be energized to control the heat distribution in the lower sub-atomization cavity 31133.

[0075] Specifically, the heating element 30 includes a first end 301 and a second end 303. The first end 301 and the second end 303 of the heating element are opposite each other in the longitudinal direction Z, and the second end 303 is the end through which the aerosol generating matrix 20 is first inserted into the atomizing chamber 311. The upper heating unit 3101 is the heating unit 310 closest to the second end 303 of the heating element, and the lower heating unit 3103 is the heating unit 310 closest to the first end 301 of the heating element. The two are also opposite each other in the longitudinal direction Z. At this time, a separator 32 is sandwiched between the upper heating unit 3101 and the lower heating unit 3103.

[0076] The upper heating element 312 is a structure in the upper heating unit 3101 used to contain the aerosol generation matrix 20. The upper heating element 332 is a component in the upper heating unit 3101 that can generate heat energy and transfer it out. The sub-atomizing cavity 3113 enclosed by the upper heating element 312 is called the upper sub-atomizing cavity 31131. When the upper heating element 332 is energized, the heat generated by the upper heating element 332 causes the infrared radiation layer 35 on the upper heating element 312 to emit infrared light to heat the medium segment 21 located in the upper sub-atomizing cavity 31131. At this time, the heating state of the upper heating element 332 will directly control the heat distribution in the upper sub-atomizing cavity 31131, thereby affecting the degree of heating of the medium segment 21 located in the upper sub-atomizing cavity 31131.

[0077] The lower heating element 314 is a structure in the lower heating unit 3103 used to contain the aerosol generation matrix 20. The lower heating element 334 is a component in the lower heating unit 3103 that can generate heat energy and transfer it out. The sub-atomizing cavity 3113 enclosed by the lower heating element 314 is called the lower sub-atomizing cavity 31133. When the lower heating element 334 is energized, the heat generated by the lower heating element 334 causes the infrared radiation layer 35 on the lower heating element 314 to emit infrared light to heat the medium segment 21 located in the lower sub-atomizing cavity 31133. At this time, the heating state of the lower heating element 334 will directly control the heat distribution in the lower sub-atomizing cavity 31133, thereby affecting the degree of heating of the medium segment 21 located in the lower sub-atomizing cavity 31133.

[0078] In summary, in this embodiment, the heating component 30 heats two sub-atomizing cavities 3113 spaced apart along the Z-direction via the upper heating unit 3101 and the lower heating unit 3103. With the heating energy of the upper heating unit 3101 and the lower heating unit 3103 controlled separately, the heating component 30 can precisely control the energy distribution in the two sub-atomizing cavities 3113. Correspondingly, the heating component 30 can precisely control the heating temperature of the upper section (located in the upper sub-atomizing cavity 31131) and the lower section (lower sub-atomizing cavity 31133) of the medium section 21, resulting in a better-tasting aerosol. Furthermore, the separator 32 prevents heat transfer between adjacent upper heating units 3101 and lower heating units 3103, preventing cross-temperature issues during the heating process of the upper and lower sections of the medium section 21, thus ensuring a better-tasting aerosol.

[0079] Please refer to Figure 1 and Figure 2 In some embodiments, the heating unit 310 further includes a middle heating unit 3105. The upper heating unit 3101, the middle heating unit 3105, and the lower heating unit 3103 are arranged sequentially at intervals along the direction from the second end 303 to the first end 301 of the heating assembly. The middle heating unit 3105 includes a middle heating element 316 and a middle heating component 336 disposed on the middle heating element 316. The middle heating element 316 forms a neutron atomizing cavity 31135, and the middle heating component 336 is configured to be energized to control the heat distribution in the neutron atomizing cavity 31135.

[0080] Specifically, in the direction from the second end 303 of the heating component to the first end 301 of the heating component in the length direction Z, the upper heating unit 3101, the middle heating unit 3105 and the lower heating unit 3103 are arranged sequentially and spaced apart from each other. At this time, a separator 32 is sandwiched between the upper heating unit 3101 and the middle heating unit 3105, and another separator 32 is sandwiched between the middle heating unit 3105 and the lower heating unit 3103.

[0081] The intermediate heating element 316 is a structure in the intermediate heating unit 3105 used to contain the aerosol generation matrix 20. The intermediate heating element 336 is a component in the intermediate heating unit 3105 that can generate and transfer heat energy. The sub-atomizing cavity 3113 enclosed by the intermediate heating element 316 is the neutron atomizing cavity 31135. When the intermediate heating element 336 is energized, the heat generated by the intermediate heating element 336 causes the infrared radiation layer 35 on the intermediate heating element 316 to emit infrared light to heat the dielectric segment 21 located in the neutron atomizing cavity 31135. At this time, the heating state of the intermediate heating element 336 will directly control the heat distribution in the neutron atomizing cavity 31135, thereby affecting the degree of heating of at least a portion of the dielectric segment 21 located in the neutron atomizing cavity 31135.

[0082] Therefore, in this embodiment, the heating component 30 heats three sub-atomizing cavities 3113 spaced apart along the Z-direction via the upper heating unit 3101, the middle heating unit 3105, and the lower heating unit 3103, respectively. This allows the heating component 30 to achieve more flexible and complex heating methods. With the heating energy of the upper heating unit 3101, the middle heating unit 3105, and the lower heating unit 3103 controlled separately, the heating component 30 can precisely control the energy distribution in the three sub-atomizing cavities 3113. Correspondingly, the heating component 30 can more precisely control the heating temperature of the upper section (located in the upper sub-atomizing cavity 31131), the middle section (located in the neutron atomizing cavity 31135), and the lower section (lower sub-atomizing cavity 31133) of the medium section 21. Moreover, the two separators 32 can block the heat transfer between two adjacent heating units 310 (between the upper heating unit 3101 and the middle heating unit 3105, and between the middle heating unit 3105 and the lower heating unit 3103), so that there will be no temperature cross-contamination problem in the heating process of the upper, middle and lower sections of the medium section 21, so that the generated aerosol has a better taste.

[0083] In this application, only one heating unit 3105 is illustrated. It can be understood that in other embodiments, the number of heating units 3105 can be two, three, or even more. Correspondingly, there are multiple neutron atomizing chambers 31135, and a separator 32 is also provided between every two adjacent heating units 3105. In this case, the heating component 30 can precisely control the energy distribution in each sub-atomizing chamber 3113. Accordingly, the heating component 30 can more precisely control the heating temperature of the upper section (located in the upper sub-atomizing chamber 31131), multiple middle sections (located in multiple neutron atomizing chambers 31135 respectively), and the lower section (lower sub-atomizing chamber 31133) of the medium section 21. Furthermore, the separator 32 can prevent heat transfer between two adjacent heating units 310 (between the upper heating unit 3101 and the middle heating unit 3105, between the middle heating units 3105 and the middle heating unit 3105, and between the middle heating unit 3105 and the lower heating unit 3103), so that there will be no cross-temperature problem in the heating process of the upper section, multiple middle sections and the lower section of the medium section 21, so that the generated aerosol has a better taste.

[0084] Please refer to Figure 1 and Figure 2 In some embodiments, the effective size of the upper heating element 332 in the length direction Z is greater than or equal to 2.5 mm and less than or equal to 4.5 mm.

[0085] Specifically, the effective size is defined as the distance D between the upper and lower edges of the area of ​​each heating element 33 covering the heating body 31 in the length direction Z. The upper edge is the tangent line perpendicular to the length direction Z in the direction between the heating element 33 and the second end 303 near the heating assembly, and the lower edge is the tangent line perpendicular to the length direction Z in the direction between the heating element 33 and the first end 301 near the heating assembly. The effective size of the upper heating element 332 can be, but is not limited to, any one or any two of 2.5mm, 2.7mm, 2.9mm, 3.3mm, 3.5mm, 3.7mm, 3.9mm, 4.1mm, 4.3mm, and 4.5mm. If the effective size of the upper heating element 332 is less than 2.5mm, the size of the upper heating element 332 is too small, the area where the upper heating element 332 generates heat is small, and less heat is generated. At least a portion of the medium section 21 in the upper atomization chamber 31131 may not be sufficiently heated, resulting in a poor-tasting aerosol. If the effective size of the upper heating element 332 is greater than 4.5mm, then the size of the upper heating element 332 is too large. In this case, the area of ​​the upper atomizing chamber 31131 is too large, which is not conducive to the flexible and precise heating of the aerosol generating matrix 20. It may also lead to a larger dimension of the heating component 30 in the length direction Z, increasing costs and hindering the miniaturization of the aerosol generating device 1000. Therefore, the effective size of the upper heating element 332 is within the above-mentioned range. This ensures that the area of ​​the upper heating element 332 that generates heat is large and generates more heat, so that the medium section 21 in the upper atomizing chamber 31131 can be fully heated, resulting in a better taste of the generated aerosol. It also allows for flexible and precise heating of the aerosol generating matrix 20 and ensures that the aerosol generating device 1000 can be miniaturized, improving the user experience.

[0086] Please refer to Figure 1 and Figure 2 In some embodiments, the effective size of the heating element 336 in the length direction Z is greater than or equal to 3.6 mm and less than or equal to 4.2 mm.

[0087] Specifically, the effective size of the intermediate heating element 336 can be, but is not limited to, any one or any two of the following: 3.6mm, 3.66mm, 3.72mm, 3.78mm, 3.84mm, 3.9mm, 3.96mm, 4.02mm, 4.1mm, and 4.2mm. If the effective size of the intermediate heating element 336 is less than 3.6mm, the size of the intermediate heating element 336 is too small, the area where the intermediate heating element 336 generates heat is small, and less heat is generated. At least a portion of the medium section 21 in the neutron atomization chamber 31135 may not be sufficiently heated, resulting in a poor taste of the generated aerosol. If the effective size of the intermediate heating element 336 is greater than 4.2mm, the size of the intermediate heating element 336 is too large. In this case, the area of ​​the neutron atomization chamber 31135 is large, which is not conducive to the flexible and precise heating of the aerosol generation matrix 20, and may also lead to a larger dimension of the heating component 30 in the length direction Z, increasing costs and hindering the miniaturization of the aerosol generation device 1000. Therefore, the effective size of the intermediate heating element 336 is within the above-mentioned range, which ensures that the area where the intermediate heating element 336 generates heat is large and generates more heat, so that the medium section 21 in the neutron atomization chamber 31135 can be fully heated, resulting in a better taste of the generated aerosol. It also allows for flexible and precise heating of the aerosol generation matrix 20, and ensures that the aerosol generation device 1000 can be miniaturized, improving the user experience.

[0088] Please refer to Figure 1 and Figure 2 In some embodiments, the effective size of the lower heating element 334 in the length direction Z is greater than or equal to 3.5 mm and less than or equal to 4.5 mm.

[0089] Specifically, the effective size of the lower heating element 334 can be, but is not limited to, any one or any two of 3.5mm, 3.6mm, 3.7mm, 3.8mm, 3.9mm, 4.0mm, 4.1mm, 4.2mm, 4.3mm, and 4.5mm. If the effective size of the lower heating element 334 is less than 3.5mm, the size of the lower heating element 334 is too small, the area where the lower heating element 334 generates heat is small, and the amount of heat generated is less. At least a portion of the medium section 21 in the lower atomization chamber 31133 may not be sufficiently heated, resulting in a poor taste of the generated aerosol. If the effective size of the lower heating element 334 is greater than 4.5mm, the size of the lower heating element 334 is too large. In this case, the area of ​​the lower atomization chamber 31133 is large, which is not conducive to the flexible and precise heating of the aerosol generation matrix 20. It may also lead to a larger size of the Z-conductive element in the length direction of the heating component 30, increasing costs and hindering the miniaturization of the aerosol generation device 1000. Therefore, the effective size of the lower heating element 334 is taken within the above-mentioned range, which can ensure that the area where the lower heating element 334 generates heat is large and generates more heat, so that the medium section 21 under the lower atomization chamber 31133 can be fully heated, resulting in a better taste of the generated aerosol. It can also flexibly and accurately heat the aerosol generation matrix 20, and ensure that the aerosol generation device 1000 can be miniaturized, thus improving the user experience.

[0090] Please refer to Figure 1 and Figure 2 In some embodiments, the ratio of the extension length of the upper heating element 332 to the width of the upper heating element 332 is greater than or equal to 30 and less than or equal to 40.

[0091] Specifically, when the pattern shape is the same, the ratio of the extension length to the width of the upper heating element 332 determines the area of ​​the upper heating element 332, and further determines the heat generated by the upper heating element 332 and the heat distribution in the upper atomizing cavity 31131. The ratio of the extension length to the width of the upper heating element 332 can be, but is not limited to, any one or any two of 30, 31, 32, 33, 34, 35, 36, 37, 38, and 40. Taking the width of the upper heating element 332 as a fixed value, if the ratio of the extension length to the width of the upper heating element 332 is less than 30, the area of ​​the upper heating element 332 is too small, the area where the upper heating element 332 generates heat is small and the amount of heat generated is less. At least a portion of the medium section 21 in the upper atomizing cavity 31131 may not be sufficiently heated, resulting in a poor-tasting aerosol. If the ratio of the extension length to the width of the upper heating element 332 is greater than 40, then the aspect ratio of the upper heating element 332 is too large. In this case, the distribution area of ​​the upper heating element 332 outside the upper heating body 312 is large, and the upper heating element 332 generates more heat, resulting in energy waste and potentially overheating, causing the aerosol to have a burnt taste. If the extension length of the upper heating element 332 is used as a fixed value, and the ratio of the extension length to the width of the upper heating element 332 is less than 30, then the aspect ratio of the upper heating element 332 is too small. In this case, the distribution area of ​​the upper heating element 332 outside the upper heating body 312 is large, and the upper heating element 332 generates more heat, resulting in energy waste and potentially overheating, causing the aerosol to have a burnt taste. If the ratio of the extension length to the width of the upper heating element 332 is greater than 40, the area of ​​the upper heating element 332 will be too small. This results in a smaller area where the upper heating element 332 generates heat, and less heat being produced. At least a portion of the medium segment 21 in the upper sub-atomization chamber 31131 may not be sufficiently heated, leading to a poor-tasting aerosol. Therefore, by using the aforementioned range for the ratio of the extension length to the width of the upper heating element 332, it is possible to ensure that the area where the upper heating element 332 generates heat is larger and generates more heat, thus ensuring that the medium segment 21 in the lower sub-atomization chamber 31133 is sufficiently heated. This also avoids overheating of the aerosol generating matrix 20, resulting in a better-tasting aerosol and improved user experience.

[0092] Please refer to Figure 1 and Figure 2 In some embodiments, the ratio of the extension length of the heating element 336 to the width of the heating element 336 is greater than or equal to 30 and less than or equal to 40.

[0093] Specifically, when the pattern shape is the same, the ratio of the extension length to the width of the intermediate heating element 336 determines the area of ​​the intermediate heating element 336, and further determines the heat generated by the intermediate heating element 336 and the heat distribution in the neutron atomizing cavity 31135. The ratio of the extension length to the width of the intermediate heating element 336 can be, but is not limited to, any one or any two of 30, 31, 32, 33, 34, 35, 36, 37, 38, and 40. Taking the width of the intermediate heating element 336 as a fixed value, if the ratio of the extension length to the width of the intermediate heating element 336 is less than 30, the area of ​​the intermediate heating element 336 is too small, the area where the intermediate heating element 336 generates heat is small and the amount of heat generated is less. At least a portion of the medium section 21 in the neutron atomizing cavity 31135 may not be sufficiently heated, resulting in a poor-tasting aerosol. If the ratio of the extension length to the width of the heating element 336 is greater than 40, the aspect ratio of the heating element 336 is too large. In this case, the distribution area of ​​the heating element 336 outside the heating body 316 is large, resulting in excessive heat generation. This leads to energy waste and may also cause overheating, resulting in a burnt aerosol. Conversely, if the ratio of the extension length to the width of the heating element 336 is less than 30, the aspect ratio of the heating element 336 is too small. In this case, the distribution area of ​​the heating element 336 outside the heating body 316 is large, resulting in excessive heat generation. This also leads to energy waste and may also cause overheating, resulting in a burnt aerosol. If the ratio of the extension length to the width of the intermediate heating element 336 is greater than 40, the area of ​​the intermediate heating element 336 will be too small. This results in a smaller area where the heating element generates heat and less heat being produced. At least a portion of the medium segment 21 in the neutron atomization chamber 31135 may not be sufficiently heated, leading to a poor-tasting aerosol. Therefore, by using the aforementioned range for the ratio of the extension length to the width of the intermediate heating element 336, it is possible to ensure that the area where the heating element 336 generates heat is larger and that more heat is produced, allowing the medium segment 21 in the lower neutron atomization chamber 31133 to be sufficiently heated. This also avoids overheating of the aerosol generating matrix 20, resulting in a better-tasting aerosol and improved user experience.

[0094] Please refer to Figure 1 and Figure 2 In some embodiments, the ratio of the extension length of the lower heating element 334 to the width of the lower heating element 334 is greater than or equal to 30 and less than or equal to 40.

[0095] Specifically, when the pattern shape is the same, the ratio of the extension length to the width of the lower heating element 334 determines the area of ​​the lower heating element 334, and further determines the heat generated by the lower heating element 334 and the heat distribution under the lower atomizing chamber 31133. The ratio of the extension length to the width of the lower heating element 334 can be, but is not limited to, any one or any two of 30, 31, 32, 33, 34, 35, 36, 37, 38, and 40. Taking the width of the lower heating element 334 as a fixed value, if the ratio of the extension length to the width of the lower heating element 334 is less than 30, then the area of ​​the lower heating element 334 is too small, the area where the lower heating element 334 generates heat is small and the amount of heat generated is less, at least a part of the medium section 21 under the lower atomizing chamber 31133 may not be sufficiently heated, and the generated aerosol has a poor taste. If the ratio of the extension length to the width of the lower heating element 334 is greater than 40, then the aspect ratio of the lower heating element 334 is too large. In this case, the distribution area of ​​the lower heating element 334 outside the lower heating body 314 is large, and the lower heating element 334 generates more heat, resulting in energy waste and potentially overheating, causing the aerosol to have a burnt taste. Using the extension length of the lower heating element 334 as a fixed value, if the ratio of the extension length to the width of the lower heating element 334 is less than 30, then the aspect ratio of the lower heating element 334 is too small. In this case, the distribution area of ​​the lower heating element 334 outside the lower heating body 314 is large, and the lower heating element 334 generates more heat, resulting in energy waste and potentially overheating, causing the aerosol to have a burnt taste. If the ratio of the extension length to the width of the lower heating element 334 is greater than 40, the area of ​​the lower heating element 334 will be too small. This results in a smaller area of ​​heat generation and less heat output, potentially leaving at least a portion of the medium section 21 under the lower atomization chamber 31133 unheated, leading to a poor-tasting aerosol. Therefore, by using the aforementioned range for the ratio of the extension length to the width of the lower heating element 334, it is possible to ensure a larger area of ​​heat generation and more heat output, thus fully heating the medium section 21 under the lower atomization chamber 31133. This also avoids overheating of the aerosol generation matrix 20, resulting in a better-tasting aerosol and improved user experience.

[0096] Please refer to Figures 1 to 4 In some embodiments, in the aerosol generating apparatus 1000 ( Figure 7 During the first heating period T1 (as shown), both the upper heating element 332 and the middle heating element 336 are energized and generate heat, while the lower heating element 334 is de-energized. The heat generated by the upper heating element 332 is q. 1-T1The heat generated by the upper heating element 332 and the middle heating element 336 accounts for 60% to 80% of the total heat generation Q1, and the heat generation q of the middle heating element 336 is... 2-T1 It accounts for 20% to 40% of the first heat generation Q1, and the first heat generation Q1 is the heat generation q of the upper heating element 332. 1-T1 The heat generated by the heating element 336 is q 2-T1 The sum. During the second heating period T2 of the aerosol generating device 1000, the upper heating element 332, the middle heating element 336, and the lower heating element 334 are all energized and generate heat. The heat generated by the upper heating element 332 is q. 1-T2 The heat generated by the upper heating element 332, the middle heating element 336, and the lower heating element 334 accounts for 10% to 30% of the total second heat generation Q2. The heat generation q of the middle heating element 336... 2-T2 The heat generation q of the lower heating element 334 accounts for 40% to 60% of the total heat generation Q2. 3-T2 It accounts for 20% to 40% of the second total heat generation Q2. The second heat generation Q2 is the heat generation q of the upper heating element 332. 1-T2 The heat generated by the heating element 336 is q 2-T2 The heat generated by the lower heating element 334 q 3-T2 The sum. During the third heating period T3 of the aerosol generating device 1000, the upper heating element 332 is de-energized, while the middle heating element 336 and the lower heating element 334 are energized and generate heat. The heat generated by the middle heating element 336 is q. 2-T3 The heat generated by the middle heating element 336 and the lower heating element 334 accounts for 20% to 40% of the total heat generation Q3. The heat generation q of the lower heating element 334... 3-T3 It accounts for 60% to 80% of the third heat generation Q3. The third heat generation Q3 is the heat generation q of the intermediate heating element 336. 2-T3 The heat generated by the lower heating element 334 q 3-T3 The sum of the first heating period and the second heating period. The end time of the first heating period is less than or equal to the start time of the second heating period, and the end time of the second heating period is less than or equal to the start time of the third heating period.

[0097] Specifically, in the above embodiment, after the aerosol generating matrix 20 is loaded into the atomizing chamber 311, the heating component 30 gradually heats the medium section 21 therein from the second end 303 of the heating component to the first end 301 of the heating component to ensure that aerosol is generated in all the user's inhalations without dry burning. The heating period of the aerosol generating device 1000 can be divided into multiple stages according to the order of the user's inhalations. Among them, the first heating period T1 is the time period during which the user starts the aerosol generating device 1000 and makes the first few inhalations. During the first heating period T1, the heating component 30 needs to heat the medium section 21 near the second end 303 of the heating component. Therefore, during the first heating period T1, the upper heating element 332 is energized to generate heat, so as to heat at least a portion of the medium segment 21 in the upper sub-atomization chamber 31131, while the middle heating element 336 is energized to generate heat, so as to heat at least a portion of the medium segment 21 in the neutron atomization chamber 31135, and the lower heating element 334 is de-energized so that the medium segment 21 in the lower sub-atomization chamber 31133 is not heated.

[0098] It should be noted that, at this time, the medium section 21 in the upper atomization chamber 31131 is the main source of aerosol generated during the first heating period T1. The main purpose of heating the medium section 21 in the neutron atomization chamber 31135 is to preheat it, so that the subsequent heating process can proceed more rapidly, allowing the aerosol generating device 1000 to generate aerosols at a faster rate and in a larger quantity. Therefore, the heat generated by the upper heating element 332 at this time is... 1-T1 Compared to the heat generation q of the heating element 336 2-T1 The heating element is relatively large, allowing for different degrees of heating of the medium segment 21 in the upper atomizing chamber 31131 and the medium segment 21 in the neutron atomizing chamber 31135. Simultaneously, because a separator 32 is provided between the upper heating unit 3101 and the middle heating unit 3105, direct heat transfer does not occur between them, resulting in better zoned heating.

[0099] The total heat generated by the upper heating element 332 and the middle heating element 336 is defined as the first heat generation Q1, at which point the heat generation q of the upper heating element 332 is... 1-T1 The ratio to the first heat generation Q1 can be, but is not limited to, any one or any two of 60%, 62%, 64%, 66%, 68%, 70%, 72%, 74%, 76%, and 80%. Correspondingly, the heat generation q of the intermediate heating element 336... 2-T1The ratio of the heat generated to the first heat generation Q1 can be, but is not limited to, any one or any two of 20%, 22%, 24%, 26%, 28%, 30%, 32%, 34%, 36%, and 40%, and the heat generation q of the heating element 336 is... 2-T1 The ratio of the first heat generation Q1 to the heat generation q of the upper heating element 332 1-T1 The sum of the ratios to the first heat generation Q1 is 100%. If the heat generation q of the upper heating element 332... 1-T1 The ratio of the heat generated to the first heat generation Q1 is less than 60%, and the heat generation q of the intermediate heating element 336 is... 2-T1 If the ratio of the heat generated to the first heat generation Q1 is greater than 40%, then the heat generation q of the upper heating element 332 is... 1-T1 If the heat output of the upper heating element 332 is too small, at least a portion of the medium section 21 in the upper atomizing chamber 31131 will not be sufficiently heated, resulting in a slower aerosol generation and a poorer taste. If the heat output of the upper heating element 332 is too small... 1-T1 The ratio of the heat generated to the first heat generation Q1 is greater than 80%, and the heat generation q of the intermediate heating element 336 is... 2-T1 If the ratio of the heat generated to the first heat generation Q1 is less than 20%, then the heat generation q of the upper heating element 332 is... 1-T1 If the temperature is too high, at least part of the medium section 21 in the upper atomization chamber 31131 may be overheated, while the medium section 21 in the neutron atomization chamber 31135 may not be preheated sufficiently, resulting in poor taste of the subsequently generated aerosol and potential issues with inconsistent quality from one sip to another.

[0100] Therefore, the heat generated by the upper heating element 332 is q 1-T1 The ratio of the first heat generation Q1 to the heat generation q of the intermediate heating element 336. 2-T1 By taking the above-mentioned range for the ratio of the first heat generation Q1, it is possible to ensure that the medium section 21 in the upper atomization chamber 31131 is fully heated, resulting in faster aerosol generation and a better taste. It can also fully preheat the medium section 21 in the neutron atomization chamber 31135, so that the subsequent aerosols have a better taste and better consistency from one puff to another, thereby improving the user experience.

[0101] The second heating period T2 is the time interval during which the user has used the aerosol generating device 1000 to heat the aerosol for a period of time, followed by several suction cycles. The end time of the first heating period is less than or equal to the start time of the second heating period. During the second heating period T2, the heating element 30 needs to heat at least a portion of the medium segment 21 that is closer to the first end 301 of the heating element than the medium segment 21 heated in the first heating period T1. The medium segment 21 heated in the first heating period T1 and the medium segment 21 heated in the second heating period T2 may overlap in the length direction Z.

[0102] Therefore, during the second heating period T2, the upper heating element 332 is energized to generate heat, thereby heating at least a portion of the medium segment 21 in the upper sub-atomization chamber 31131. At the same time, the middle heating element 336 is energized to generate heat, thereby heating at least a portion of the medium segment 21 in the neutron atomization chamber 31135. The lower heating element 334 is energized to generate heat, thereby heating at least a portion of the medium segment 21 in the lower sub-atomization chamber 31133.

[0103] It should be noted that, at this time, the medium segment 21 in the neutron atomization chamber 31135 is the main source of aerosol generated during the second heating period T2. The upper heating element 332 generates heat by being energized, ensuring that the medium segment 21 in the upper atomization chamber 31131 continues to be heated, and preventing the temperature of the medium segment 21 corresponding to the upper heating element 332 from becoming too low, which would cause excessive heat transfer to the medium segment 21 of the adjacent middle heating element 336, resulting in insufficient heating of the medium segment 21 in the neutron atomization chamber 31135. The main purpose of heating the medium segment 21 in the lower atomization chamber 31133 is to preheat it, so that the subsequent heating process can proceed more quickly, allowing the aerosol generating device 1000 to generate aerosols at a faster rate and in a larger quantity. Therefore, the heat generated by the middle heating element 336 at this time is... 2-T2 Compared to the heat generated by the upper heating element 332, q 1-T2 The heat generated by the lower heating element 334 q 3-T2 All are relatively large, allowing for different degrees of heating of the medium segment 21 in the upper atomizing chamber 31131, the neutron atomizing chamber 31135, and the lower atomizing chamber 31133. Simultaneously, since partitions 32 are provided between the upper heating unit 3101 and the middle heating unit 3105, and between the middle heating unit 3105 and the lower heating unit 3103, direct heat transfer does not occur between these units, resulting in better zoned heating.

[0104] The total heat generated by the upper heating element 332, the middle heating element 336, and the lower heating element 334 is defined as the second heat generation Q2, at which point the heat generation q of the upper heating element 332 is... 1-T2 The ratio of the heat generated to the second heat generation Q2 can be, but is not limited to, any one or any two of 10%, 12%, 14%, 16%, 18%, 20%, 22%, 24%, 26%, and 30%, where the heat generation q of the heating element 336 is... 2-T2 The ratio of the heat generated to the second heat generation Q2 can be, but is not limited to, any one or any two of 40%, 42%, 44%, 46%, 48%, 50%, 52%, 54%, 56%, and 60%, corresponding to the heat generation q of the lower heating element 334. 3-T2The ratio of the heat generated to the second heat generation Q2 can be, but is not limited to, any value between any two of 20%, 22%, 24%, 26%, 28%, 30%, 32%, 34%, 36%, and 40%. Furthermore, the heat generation q of the lower heating element 334... 3-T2 The ratio of the second heat generation Q2 to the heat generation q of the intermediate heating element 336 2-T2 The ratio of the second heat generation Q2 to the heat generation q of the upper heating element 332 1-T2 The sum of the ratios to the second heat generation Q2 is 100%.

[0105] If the heat generated by the heating element 332 is q 1-T2 If the ratio of the heat generated to the second heat generation Q2 is less than 10%, then the heat generation q of the upper heating element 332 is... 1-T2 If the heat output of the upper heating element 332 is too small, excessive heat from the medium segment 21 in the neutron atomizing chamber 31135 may be transferred to the medium segment 21 in the upper atomizing chamber 31131. At least a portion of the medium segment 21 in the neutron atomizing chamber 31135 may not be sufficiently heated, resulting in slower aerosol generation and a poorer aerosol taste. If the heat output of the upper heating element 332 is too small... 1-T2 If the ratio of the heat generated to the second heat generation Q2 is greater than 30%, then the heat generation q of the upper heating element 332 is... 1-T2 If the temperature is too high, at least part of the dielectric section 21 in the neutron atomizing chamber 31135 may not be sufficiently heated, resulting in slower aerosol generation and a poorer aerosol taste. Furthermore, the dielectric section 21 in the lower neutron atomizing chamber 31133 may not be adequately preheated, leading to subsequent aerosol generation with a poor taste and potential inconsistencies between different whiffs. Therefore, the heat output q of the intermediate heating element 336 needs to be considered here. 2-T2 The ratio of the second heat generation Q2 to the heat generation q of the lower heating element 334 3-T2 A detailed analysis of the ratio to the second heat generation Q2.

[0106] If the heat generated by the heating element 336 is q 2-T2 If the ratio of the heat generated to the second heat generation Q2 is less than 40%, then the heat generation q of the intermediate heating element 336 is... 2-T2 If the temperature is too low, the medium section 21 in the neutron atomization chamber 31135 may not be sufficiently heated, resulting in slower aerosol generation and a poorer aerosol taste. If the heat output q of the heating element 336 is too low... 2-T2 The ratio of the heat generated to the second heat generation Q2 is greater than 60%, and the heat generation q of the intermediate heating element 336 is... 2-T2 If the temperature is too high, at least part of the medium segment 21 in the neutron atomizing chamber 31135 may be overheated. In addition, the medium segment 21 in the lower neutron atomizing chamber 31133 may not be preheated sufficiently, resulting in poor taste of the subsequently generated aerosol and potential issues with inconsistent quality from one puff to another.

[0107] If the heat generated by the heating element 334 is q3-T2 If the ratio of the heat generated to the second heat generation Q2 is less than 20%, then the heat generation q of the lower heating element 334 is... 3-T2 If the temperature is too low, the medium section 21 in the lower atomization chamber 31133 may not be preheated sufficiently, resulting in a poor taste of the subsequently generated aerosol and potential inconsistencies between each puff. Furthermore, the intermediate heating element 336 may generate excessive heat (q). 2-T2 If the temperature is too high, at least a portion of the dielectric section 21 in the neutron atomizing cavity 31135 may be overheated, and the heat generated by the upper heating element 332 may also be excessive. 1-T2 If the temperature is too high, it can lead to dry burning, and at least a portion of the dielectric section 21 in the neutron atomization chamber 31135 may not be sufficiently heated. This needs to be considered in conjunction with the heat generation q of the heating element 332. 1-T2 The ratio of the second heat generation Q2 to the heat generation q of the intermediate heating element 336 2-T2 A detailed analysis of the ratio to the second heat generation Q2 is needed. If the heat generation q of the lower heating element 334... 3-T2 If the ratio of the heat generated to the second heat generation Q2 is greater than 40%, then the heat generation q of the lower heating element 334 is... 3-T2 If the temperature is too high, at least part of the medium section 21 in the neutron atomizing chamber 31135 may not be heated sufficiently, resulting in a slower aerosol generation and a poorer taste. Furthermore, the medium section 21 in the neutron atomizing chamber 31133 may be overheated, leading to a poorer taste in the subsequently generated aerosol and potential issues with inconsistent quality from one sip to another.

[0108] Therefore, the heat generated by the upper heating element 332 is q 1-T2 The ratio of the second heat generation Q2 to the heat generation q of the intermediate heating element 336 2-T2 The ratio of the second heat generation Q2 to the heat generation q of the lower heating element 334. 3-T2 The ratio of the second heat generation Q2 is set within the above range. This ensures that the temperature of the medium section 21 in the upper atomizing chamber 31131 does not drop too low and absorb too much heat from the medium section 21 in the neutron atomizing chamber 31135. It also ensures that the medium section 21 in the neutron atomizing chamber 31135 is fully heated, resulting in faster aerosol generation and better aerosol taste. Furthermore, it can fully preheat the medium section 21 in the lower atomizing chamber 31133, so that the subsequently generated aerosol has a better taste and better consistency from puff to puff, thus improving the user experience.

[0109] The third heating period T3 is the time period after the user has started the aerosol generating device 1000 for a relatively long time and then sucked in several times. The end time of the second heating period is less than or equal to the start time of the third heating period. During the third heating period T3, the heating component 30 needs to heat at least a portion of the medium segment 21 that is closer to the first end 301 of the heating component than the medium segment 21 heated in the second heating period T2. The medium segment 21 heated in the third heating period T3 may overlap with the medium segment 21 heated in the second heating period T2 in the length direction Z.

[0110] Therefore, during the third heating period T2, the middle heating element 336 is energized to generate heat, so as to heat at least a portion of the medium segment 21 in the neutron atomizing cavity 31135, and the lower heating element 334 is energized to generate heat, so as to heat at least a portion of the medium segment 21 in the lower atomizing cavity 31133, and the upper heating element 332 is de-energized so that the medium segment 21 in the upper atomizing cavity 31131 is no longer heated.

[0111] It should be noted that at this time, the medium segment 21 in the lower atomization chamber 31133 is the main source of aerosol generated during the third heating period T3. The intermediate heating element 336 generates heat by being energized, ensuring that the medium segment 21 in the neutron atomization chamber 31135 continues to be heated. This prevents the temperature of the medium segment 21 corresponding to the intermediate heating element 336 from becoming too low, which would cause excessive heat transfer to the medium segment 21 of the adjacent lower heating element 334, resulting in insufficient heating of the medium segment 21 in the lower atomization chamber 31133. Heating of the medium segment 21 in the upper atomization chamber 31131 is stopped to avoid dry burning, which would result in a poor-tasting aerosol. Therefore, the heat generated by the intermediate heating element 336 at this time is q. 2-T3 In comparison, the heat generation q of heating element 334 3-T3 The heating element is relatively small, allowing for different degrees of heating of the medium segment 21 in the upper sub-atomizing chamber 31131, the neutron sub-atomizing chamber 31135, and the lower sub-atomizing chamber 31133. Simultaneously, because a separator 32 is provided between the upper heating unit 3101 and the middle heating unit 3105, and between the middle heating unit 3105 and the lower heating unit 3103, direct heat transfer does not occur between the upper heating unit 3101 and the middle heating unit 3105, or between the middle heating unit 3105 and the lower heating unit 3103, resulting in better zoned heating.

[0112] The total heat generated by the middle heating element 336 and the lower heating element 334 is defined as the third heat generation Q3, at which point the heat generation q of the middle heating element 336 is... 2-T3The ratio of the heat generated to the third heat generation Q3 can be, but is not limited to, any one or any two of the following: 20%, 22%, 24%, 26%, 28%, 30%, 32%, 34%, 36%, and 40%. The corresponding heat generation q of the lower heating element 334... 3-T3 The ratio of the heat generated to the third heat generation Q3 can be, but is not limited to, any one or any two of 60%, 62%, 64%, 66%, 68%, 70%, 72%, 74%, 76%, and 80%, and the heat generation q of the lower heating element 334 is... 3-T3 The ratio of the heat generated by the third heat source Q3 to the heat generated by the intermediate heating element 336 q 2-T3 The sum of the ratios to the third heat generation Q3 is 100%. If the heat generation q of the intermediate heating element 336... 2-T3 The ratio of the heat generated by the third heat generation Q3 to less than 20% indicates that the heat generated by the lower heating element 334 is q. 3-T3 If the ratio of the heat generated to the third heat generation Q3 is greater than 80%, then the heat generation q of the lower heating element 334 is... 3-T3 If the temperature is too high, at least a portion of the medium section 21 in the lower atomization chamber 31133 may be overheated, while the temperature of the medium section 21 in the neutron atomization chamber 31135 remains low. This large temperature difference results in a poor taste of the subsequently generated aerosol and may lead to inconsistent flavor across different whiffs. If the heat generated by the heating element 336 is too high... 2-T3 The ratio of the heat generated by the third heat generation Q3 to the heat generated by the lower heating element 334 is greater than 40%. 3-T3 If the ratio of the heat generated to the third heat generation Q3 is less than 60%, then the heat generation q of the lower heating element 334 is... 3-T3 If the temperature is too low, at least part of the medium section 21 in the neutron atomization chamber 31133 will not be sufficiently heated, resulting in a slower aerosol generation and a poorer taste. Furthermore, the medium section 21 in the neutron atomization chamber 31135 may experience dry burning, leading to a poorer taste in the subsequent aerosol generation.

[0113] Therefore, the heat generated by the heating element 336 is q 2-T3 The ratio of the third heat generation Q3, and the heat generation q of the lower heating element 334. 3-T3 The ratio of the third heat generation Q3 is within the above range. This ensures that the medium section 21 in the lower atomization chamber 31133 is fully heated, resulting in faster aerosol generation and better taste. It also prevents the medium section 21 in the neutron atomization chamber 31135 from becoming too cold or dry-burning, thus ensuring better taste and consistency of the aerosol generated in subsequent sips, thereby improving the user experience.

[0114] In summary, the heat generation of each heating unit 310 varies during different heating periods. Within the first heating period T1, the heat generation q of the upper heating element 332 corresponds to the number of preceding suction ports. 1-T1The heat output q of the heating element is greater than 336. 2-T1 This ensures that the medium section 21 in the upper atomizing chamber 31131 is fully heated, and the medium section 21 in the neutron atomizing chamber 31135 is preheated; within the second heating period T2, the heat generated by the intermediate heating element 336 is q. 2-T2 The heat generated by the upper heating element 332 is greater than q. 1-T2 and the heat generated by the lower heating element 334 q 3-T2 This ensures that the medium section 21 in the neutron atomizing chamber 31135 is fully heated, the medium section 21 in the upper neutron atomizing chamber 31131 maintains its temperature, and the medium section 21 in the lower neutron atomizing chamber 31133 is preheated; during the third heating period T3, the heat generated q of the lower heating element 334 corresponds to the number of subsequent suction ports. 3-T3 The heat output q of the heating element is greater than 336. 2-T3 This ensures that the medium section 21 in the lower atomization chamber 31133 is fully heated, while the medium section 21 in the neutron atomization chamber 31135 maintains its temperature. At this time, by separately controlling the upper heating element 332, the middle heating element 336, and the lower heating element 334, flexible heating of the medium section 21 of the aerosol generating matrix 20 is achieved, resulting in a better-tasting aerosol and a better user experience with the aerosol generating device 1000.

[0115] Please refer to Figures 1 to 4In some embodiments, in the direction from the second end 303 to the first end 301 of the heating element, the upper heating element 332 includes an upper heating region 3321 and a lower heating region 3323 arranged sequentially; the middle heating element 336 includes an upper heating region 3361, a middle heating region 3363, and a lower heating region 3365 arranged sequentially; and the lower heating element 334 includes an upper heating region 3341, a middle heating region 3343, and a lower heating region 3345 arranged sequentially. When the upper heating element 332 is energized and generates heat, the heat generated by the upper heating region 3321 accounts for 60% to 80% of the total heat generated by the upper heating element 332, and the heat generated by the lower heating region 3323 accounts for 20% to 40% of the total heat generated by the upper heating element 332. When the intermediate heating element 336 is energized and generates heat, the heat generated by the upper heating zone 3361 of the intermediate heating element accounts for 20% to 40% of the heat generated by the intermediate heating element 336, the heat generated by the middle heating zone 3363 of the intermediate heating element accounts for 40% to 60% of the heat generated by the intermediate heating element 336, and the heat generated by the lower heating zone 3365 of the intermediate heating element accounts for 10% to 30% of the heat generated by the intermediate heating element 336. When the lower heating element 334 is energized and generates heat, the heat generated by the upper heating zone 3341 of the lower heating element accounts for 10% to 30% of the heat generated by the intermediate heating element 336, the heat generated by the middle heating zone 3343 of the lower heating element accounts for 40% to 60% of the heat generated by the intermediate heating element 336, and the heat generated by the lower heating zone 3345 of the lower heating element accounts for 20% to 40% of the heat generated by the intermediate heating element 336.

[0116] Specifically, in the direction from the second end 303 to the first end 301 of the heating element in the length direction Z, the upper heating element 332 includes an upper heating region 3321 and a lower heating region 3323 arranged sequentially. The heat generation of the upper heating region 3321 and the heat generation of the lower heating region 3323 of the upper heating element can be controlled separately. In some embodiments, the energizing state of the upper heating region 3321 and the energizing state of the lower heating region 3323 of the upper heating element can be controlled separately to achieve separate control of heat generation. In other embodiments, the parameters of the upper heating region 3321 (explained as above) are different from the parameters of the lower heating region 3323 of the upper heating element, in which case separate control of heat generation can be achieved under the same energizing state.

[0117] When the upper heating element 332 is energized and generates heat (corresponding to the first heating period T1 and the second heating period T2), the heat generated by the upper heating area 3321 of the upper heating element accounts for 60% to 80% of the heat generated by the upper heating element 332. At this time, the ratio of the heat generated by the upper heating area 3321 to the heat generated by the upper heating element 332 can be, but is not limited to, any one or any two of 60%, 62%, 64%, 66%, 68%, 70%, 72%, 74%, 76%, and 80%. Correspondingly, the heat generated by the lower heating zone 3323 of the upper heating element accounts for 20% to 40% of the total heat generated by the upper heating element 332. The ratio of the heat generated by the lower heating zone 3323 of the upper heating element to the heat generated by the upper heating element 332 can be, but is not limited to, any one or any two of 20%, 22%, 24%, 26%, 28%, 30%, 32%, 34%, 36%, and 40%, and the sum of the ratio of the heat generated by the upper heating zone 3321 of the upper heating element to the heat generated by the upper heating element 332 and the ratio of the heat generated by the lower heating zone 3323 of the upper heating element to the heat generated by the upper heating element 332 is 100%.

[0118] Since both the upper heating element 332 and the middle heating element 336 are energized and generating heat when the upper heating element 332 is energized, at least a portion of the heat from the medium section 21 in the neutron atomizing cavity 31135 is directly transferred to the medium section 21 in the upper atomizing cavity 31131. This portion of the temperature increases the temperature of the medium section 21 in the upper atomizing cavity 31131 corresponding to the lower heating zone 3323 of the upper heating element. Therefore, by setting the ratio of the heat generated by the lower heating zone 3323 of the upper heating element to the heat generated by the upper heating element 332 to be less than the ratio of the heat generated by the upper heating zone 3321 of the upper heating element to the heat generated by the upper heating element 332, the temperature consistency of the medium section 21 in the upper atomizing cavity 31131 corresponding to the upper heating zone 3321 of the upper heating element and the medium section 21 in the upper atomizing cavity 31131 corresponding to the lower heating zone 3323 of the upper heating element is better, resulting in a more uniform temperature distribution during heating and a better-tasting aerosol.

[0119] In the direction from the second end 303 to the first end 301 of the heating element, the intermediate heating element 336 includes an upper heating region 3361, a middle heating region 3363, and a lower heating region 3365 arranged sequentially. The heat generation of the upper heating region 3361, the middle heating region 3363, and the lower heating region 3365 of the intermediate heating element can be controlled separately. In some embodiments, the energizing states of the upper heating region 3361, the middle heating region 3363, and the lower heating region 3365 of the intermediate heating element can be controlled separately to achieve separate control of heat generation. In other embodiments, the parameters of the upper heating region 3361, the middle heating region 3363, and the lower heating region 3365 of the intermediate heating element are different, in which case separate control of heat generation can be achieved under the same energizing state.

[0120] When the heating element 336 is energized and generates heat (corresponding to the first heating period T1, the second heating period T2, and the third heating period T3), the heat generated by the upper heating zone 3361 of the heating element accounts for 20% to 40% of the heat generated by the heating element 336. The ratio of the heat generated by the upper heating zone 3361 to the heat generated by the heating element 336 can be, but is not limited to, any one or any two of 20%, 22%, 24%, 26%, 28%, 30%, 32%, 34%, 36%, and 40%. Correspondingly, the heat generation of the central heating zone 3363 of the central heating element accounts for 40% to 60% of the heat generation of the central heating element 336. The ratio of the heat generation of the central heating zone 3363 to the heat generation of the central heating element 336 can be, but is not limited to, any one or any two of 40%, 42%, 44%, 46%, 48%, 50%, 52%, 54%, 56%, and 60%. The heat generation of the lower heating zone 3365 of the central heating element accounts for 10% to 30% of the heat generation of the central heating element 336. The ratio of the heat generation of the lower heating zone 3365 to the heat generation of the central heating element 336 can be, but is not limited to, any one or any two of 10%, 12%, 14%, 16%, 18%, 20%, 22%, 24%, 26%, and 30%. Furthermore, the sum of the ratio of the heat generated by the upper heating zone 3361 of the middle heating element to the heat generated by the middle heating element 336, the ratio of the heat generated by the middle heating zone 3363 of the middle heating element to the heat generated by the middle heating element 336, and the ratio of the heat generated by the lower heating zone 3365 of the middle heating element to the heat generated by the middle heating element 336 is 100%.

[0121] Since at least one of the upper heating element 332 and the lower heating element 334 is also energized and generating heat when the middle heating element 336 is energized and generating heat.

[0122] During the first heating period T1, the upper heating element 332 and the middle heating element 336 are energized to generate heat. At least a portion of the heat from the medium section 21 in the upper atomizing cavity 31131 is directly transferred to the medium section 21 in the neutron atomizing cavity 31135. This portion of the temperature increases the temperature of the medium section 21 in the neutron atomizing cavity 31135 corresponding to the upper heating area 3361 of the middle heating element. Therefore, the ratio of the heat generated by the upper heating area 3361 of the middle heating element to the heat generated by the middle heating element 336 is set to be less than the ratio of the heat generated by the middle heating area 3363 of the middle heating element to the heat generated by the middle heating element 336. Furthermore, at least a portion of the heat from the medium segment 21 in the neutron atomizing cavity 31135 corresponding to the middle heating zone 3363 of the middle heating element is directly transferred in the medium segment 21 to the medium segment 21 in the neutron atomizing cavity 31135 corresponding to the upper heating zone 3361 of the middle heating element, and to the medium segment 21 in the neutron atomizing cavity 31135 corresponding to the lower heating zone 3365 of the middle heating element. At this time, the temperature uniformity of the medium segment 21 in the neutron atomizing cavity 31135 is better, the temperature distribution is more uniform during heating, and the generated aerosol has a better taste.

[0123] During the second heating period T2, the upper heating element 332, the middle heating element 336, and the lower heating element 334 are energized to generate heat. At least a portion of the heat from the medium segment 21 in the upper atomizing cavity 31131 is directly transferred to the medium segment 21 in the neutron atomizing cavity 31135. This portion of the temperature increases the temperature of the medium segment 21 in the neutron atomizing cavity 31135 corresponding to the upper heating zone 3361 of the middle heating element. Simultaneously, at least a portion of the heat from the medium segment 21 in the lower atomizing cavity 31133 is directly transferred to the medium segment 21 in the neutron atomizing cavity 31135. This portion of the temperature increases the temperature of the medium segment 21 in the neutron atomizing cavity 31135 corresponding to the lower heating zone 3365 of the middle heating element. Therefore, the ratio of the heat generated in the upper heating zone 3361 of the intermediate heating element to the heat generated in the intermediate heating element 336 is less than the ratio of the heat generated in the middle heating zone 3363 of the intermediate heating element to the heat generated in the middle heating element 336, and the ratio of the heat generated in the lower heating zone 3365 of the intermediate heating element to the heat generated in the middle heating element 336 is less than the ratio of the heat generated in the middle heating zone 3363 of the intermediate heating element to the heat generated in the middle heating element 336. Furthermore, at least a portion of the heat from the medium section 21 in the neutron atomizing cavity 31135 corresponding to the middle heating zone 3363 of the intermediate heating element is directly transferred in the medium section 21 to the medium section 21 in the neutron atomizing cavity 31135 corresponding to the upper heating zone 3361 of the intermediate heating element, and to the medium section 21 in the neutron atomizing cavity 31135 corresponding to the lower heating zone 3365 of the intermediate heating element. At this time, the temperature uniformity of the medium section 21 in the neutron atomization chamber 31135 is good, the temperature distribution is more uniform during the heating process, and the generated aerosol has a better taste.

[0124] During the third heating period T3, the intermediate heating element 336 and the lower heating element 334 are energized to generate heat. At least a portion of the heat from the medium section 21 in the lower atomizing chamber 31133 is directly transferred to the medium section 21 in the neutron atomizing chamber 31135. This portion of the temperature will cause the temperature of the medium section 21 in the neutron atomizing chamber 31135 corresponding to the lower heating area 3365 of the intermediate heating element to rise. Therefore, the ratio of the heat generated in the lower heating area 3365 of the intermediate heating element to the heat generated in the intermediate heating element 336 is set to be less than the ratio of the heat generated in the middle heating area 3363 of the intermediate heating element to the heat generated in the middle heating element 336. Furthermore, at least a portion of the heat from the medium segment 21 in the neutron atomizing cavity 31135 corresponding to the middle heating zone 3363 of the middle heating element is directly transferred in the medium segment 21 to the medium segment 21 in the neutron atomizing cavity 31135 corresponding to the upper heating zone 3361 of the middle heating element, and to the medium segment 21 in the neutron atomizing cavity 31135 corresponding to the lower heating zone 3365 of the middle heating element. At this time, the temperature uniformity of the medium segment 21 in the neutron atomizing cavity 31135 is better, the temperature distribution is more uniform during heating, and the generated aerosol has a better taste.

[0125] In the direction from the second end 303 to the first end 301 of the heating element in the length direction Z, the lower heating element 334 includes an upper heating region 3341, a middle heating region 3343, and a lower heating region 3345 arranged sequentially. The heat generation of the upper heating region 3341, the middle heating region 3343, and the lower heating region 3345 of the lower heating element can be controlled separately. In some embodiments, the energizing states of the upper heating region 3341, the middle heating region 3343, and the lower heating region 3345 of the lower heating element can be controlled separately to achieve separate control of heat generation. In other embodiments, the parameters of the upper heating region 3341, the middle heating region 3343, and the lower heating region 3345 of the lower heating element are different, in which case separate control of heat generation can be achieved under the same energizing state.

[0126] When the lower heating element 334 is energized and generates heat (corresponding to the second heating period T2 and the third heating period T3), the heat generated by the upper heating area 3341 of the lower heating element accounts for 10% to 30% of the heat generated by the middle heating element 336. At this time, the ratio of the heat generated by the upper heating area 3341 of the lower heating element to the heat generated by the lower heating element 334 can be, but is not limited to, any one or any two of 10%, 12%, 14%, 16%, 18%, 20%, 22%, 24%, 26%, and 30%. Correspondingly, the heat generation of the middle heating zone 3343 of the lower heating element accounts for 40% to 60% of the heat generation of the middle heating element 336. The ratio of the heat generation of the middle heating zone 3343 to the heat generation of the lower heating element 334 can be, but is not limited to, any one or any two of 40%, 42%, 44%, 46%, 48%, 50%, 52%, 54%, 56%, and 60%. The heat generation of the lower heating zone 3345 of the lower heating element accounts for 20% to 40% of the heat generation of the middle heating element 336. The ratio of the heat generation of the lower heating zone 3345 to the heat generation of the lower heating element 334 can be, but is not limited to, any one or any two of 20%, 22%, 24%, 26%, 28%, 30%, 32%, 34%, 36%, and 40%. Furthermore, the sum of the ratio of the heat generated by the upper heating zone 3341 of the lower heating element to the heat generated by the lower heating element 334, the ratio of the heat generated by the middle heating zone 3343 of the lower heating element to the heat generated by the lower heating element 334, and the ratio of the heat generated by the lower heating zone 3345 of the lower heating element to the heat generated by the lower heating element 334 is 100%.

[0127] Since the lower heating element 334 generates heat when it is energized, the middle heating element 336 also generates heat when it is energized. At least a portion of the heat from the medium section 21 in the neutron atomizing cavity 31135 is directly transferred to the medium section 21 in the lower sub-atomizing cavity 31133. This portion of the temperature will cause the temperature of the medium section 21 in the lower sub-atomizing cavity 31133 corresponding to the upper heating area 3341 of the lower heating element to rise. Therefore, the ratio of the heat generated in the upper heating area 3341 of the lower heating element to the heat generated in the lower heating element 334 is set to be less than the ratio of the heat generated in the middle heating area 3343 of the lower heating element to the heat generated in the lower heating element 334. Furthermore, at least a portion of the heat from the medium segment 21 in the lower sub-atomization chamber 31133 corresponding to the middle heating zone 3343 of the lower heating element is directly transferred in the medium segment 21 to the medium segment 21 in the lower sub-atomization chamber 31133 corresponding to the upper heating zone 3341 of the lower heating element, and to the medium segment 21 in the lower sub-atomization chamber 31133 corresponding to the lower heating zone 3345 of the lower heating element. At this time, the temperature uniformity of the medium segment 21 in the lower sub-atomization chamber 31133 is better, the temperature distribution is more uniform during heating, and the generated aerosol has a better taste.

[0128] In summary, the heat generation of different heating zones of each heating element 33 is controlled separately during different heating periods, so that the temperature consistency of the medium section 21 in the upper atomizing chamber 31131, neutron atomizing chamber 31135 and lower atomizing chamber 31133 is good in any time period. During the heating process, the temperature distribution in the upper atomizing chamber 31131, neutron atomizing chamber 31135 and lower atomizing chamber 31133 is more uniform, the generated aerosol has a better taste, and the user has a better experience with the aerosol generating device 1000.

[0129] Please refer to Figure 1 and Figure 2 In some embodiments, the heating element 33 includes a first conductive end and a second conductive end in its extending direction. The heating unit 310 further includes a first conductive element 381, a first electrical connector 391, a second conductive element 383, and a second electrical connector 393. The first conductive end is electrically connected to the first electrical connector 391 via the first conductive element 381, and the first electrical connector 391 is configured to be electrically connected to a first electrode of an external circuit. The second conductive end is electrically connected to the second electrical connector 393 via the second conductive element 383, and the second electrical connector 393 is configured to be electrically connected to a second electrode of an external circuit. The polarity of the first electrode is opposite to that of the second electrode.

[0130] Specifically, each of the heating elements 33 (upper heating element 332, middle heating element 336, and lower heating element 334) is provided with a connection portion for realizing electrical connection, namely a first conductive end and a second conductive end. The first conductive end and the second conductive end are opposite each other and are located at two opposite free ends of the heating element 33, so that the area between the first conductive end and the second conductive end is the entire area of ​​the heating element 33. Figure 3 and Figure 4 The figures below are perspective views of the heating element 33 and partial structure unfolded diagrams of the heating assembly 30 in two embodiments of this application. The lower figure is a schematic diagram of the common structure composed of the heating body 31, the heating element 33, the first conductive end, and the second conductive end cut along the length direction Z and laid flat. The upper figure is a perspective view of the heating element 33.

[0131] The external circuit (not shown) includes a structure for supplying power to the heating element 33 (e.g., the battery assembly 300 mentioned below), and also includes a first electrode and a second electrode with opposite polarities. In one example, the first electrode is a positive electrode and the second electrode is a negative electrode; for example, the first electrode may be the positive electrode of the battery assembly 300 and the second electrode may be the negative electrode of the battery assembly 300. In another example, the first electrode is a negative electrode and the second electrode is a positive electrode; for example, the first electrode may be the negative electrode of the battery assembly 300 and the second electrode may be the positive electrode of the battery assembly 300.

[0132] The first electrical connector 391 is a structure used to electrically connect the first conductive terminal of the heating element 33 to the first electrode of the external circuit. The first electrical connector 391 can be, but is not limited to, a wire, a flexible circuit board, or a metal sheet. This application uses the first electrical connector 391 as a wire as an example. Please refer to [reference needed]. Figure 1 and Figure 2 The first electrical connector 391 is deformable to allow for more flexible layout and to avoid interference with other structures. The first conductive element 381 is a structure in the heating unit 310 used to achieve a stable electrical connection between the first conductive end of the heating element 33 and the first electrical connector 391. The first conductive element 381 is connected to both the first conductive end of the heating element 33 and the first electrical connector 391. The second electrical connector 393 is a structure used to electrically connect the second conductive end of the heating element 33 to the second electrode of an external circuit. The second electrical connector 393 can be, but is not limited to, a wire, a flexible circuit board, or a metal sheet. This application uses the second electrical connector 393 as an example of a wire; please refer to [reference needed]. Figure 1 and Figure 2 The second electrical connector 393 is deformable to allow for more flexible layout and to avoid interference with other structures. The second conductive element 383 is a structure in the heating unit 310 used to achieve a stable electrical connection between the second conductive end of the heating element 33 and the second electrical connector 393. The second conductive element 383 is connected to both the second conductive end of the heating element 33 and the second electrical connector 393.

[0133] When the first electrode is electrically connected to the first conductive terminal through the first conductive element 381 and the second electrode is electrically connected to the second conductive terminal through the second conductive element 383, the external circuit and the heating element 33 together form a closed loop for current flow. When the battery assembly 300 in the external circuit supplies power, the current flows through the heating element 33, causing the heating element 33 to generate heat. The heat excites the infrared radiation layer 35 to radiate infrared light and heats the aerosol generation matrix 20 to generate aerosol.

[0134] Please refer to Figure 1 and Figure 2 In some embodiments, the separator 32 is a zirconia separator 32. Since zirconia has good heat resistance and low thermal conductivity, when a zirconia separator 32 is used, it can effectively block or slow down the transfer of heat along the length direction Z. Furthermore, the separator 32 can better seal the gaps between the heating elements 310. Therefore, on the one hand, the separator 32 can better isolate the transfer of heat along the length direction Z, avoiding mutual interference between the heat generated by different heating elements 310, allowing for more accurate control of heat distribution by the heating assembly 30, and resulting in a better-tasting aerosol. On the other hand, the separator 32 can better prevent aerosol leakage to the outside of the heating element 31, preventing leaked aerosol from affecting the normal operation of other components and extending the service life of the aerosol generating device 1000.

[0135] Please refer to Figure 1 and Figure 2 In some embodiments, the separator 32 is a mica separator 32. Because mica has good heat resistance and low thermal conductivity, when a mica separator 32 is used, it can effectively block or slow down the transfer of heat along the length direction Z. Furthermore, the separator 32 can better seal the gaps between the heating elements 310. Therefore, on the one hand, the separator 32 can better isolate the transfer of heat along the length direction Z, avoiding mutual interference between the heat generated by different heating elements 310, allowing for more accurate control of heat distribution by the heating assembly 30, and resulting in a better-tasting aerosol. On the other hand, the separator 32 can better prevent aerosol leakage to the outside of the heating element 31, preventing leaked aerosol from affecting the normal operation of other components and extending the service life of the aerosol generating device 1000.

[0136] Please refer to Figure 1 and Figure 2 In some embodiments, the separator 32 is a vapor phase gel separator 32. Because vapor phase gels have good heat resistance and mechanical properties, when a vapor phase gel separator 32 is used, it can effectively block or slow down the transfer of heat along the length direction Z. Furthermore, the separator 32 can better seal the gaps between the heating units 310. Therefore, on the one hand, the separator 32 can better isolate the transfer of heat along the length direction Z, avoiding mutual interference between the heat generated by different heating units 310, allowing for more accurate control of heat distribution by the heating assembly 30, and resulting in a better-tasting aerosol. On the other hand, the separator 32 can better prevent aerosol leakage to the outside of the heating element 31, preventing leaked aerosol from affecting the normal operation of other components and extending the service life of the aerosol generating device 1000.

[0137] Please refer to Figure 1 and Figure 2In some embodiments, the separator 32 is a rubber separator 32. Because rubber has good heat resistance and mechanical properties, when a rubber separator 32 is used, it can effectively block or slow down the transfer of heat along the length direction Z. Furthermore, the separator 32 can better seal the gaps between the heating units 310. Therefore, on the one hand, the separator 32 can better isolate the transfer of heat along the length direction Z, avoiding mutual interference between the heat generated by different heating units 310, allowing for more accurate control of heat distribution by the heating assembly 30, resulting in a better-tasting aerosol. On the other hand, the separator 32 can better prevent aerosol leakage to the outside of the heating element 31, preventing leaked aerosol from affecting the normal operation of other components and extending the service life of the aerosol generating device 1000.

[0138] Please refer to Figure 1 and Figure 2 In some embodiments, the heating element 31 is provided with a perforation that penetrates the sidewall of the heating element 31 and is configured to allow infrared light to enter the atomization chamber 311.

[0139] Specifically, the perforation (not shown) is a structure on the heating element 31 used to increase the proportion of infrared light entering the atomization cavity 311. The perforation penetrates the sidewall of the heating element 31 to form a passage for infrared light. At this time, infrared light directly emitted by the infrared radiation layer 35, and / or infrared light reflected by the reflector and transmitted to the atomization cavity 311, can enter the atomization cavity 311 through the perforation to heat the aerosol generation matrix 20 located in the atomization cavity 311.

[0140] In one embodiment, the heating element 31 is a light-transmitting ceramic tube, and the infrared radiation layer 35 is disposed on the outer side of the sidewall of the heating element 31. A portion of the infrared light radiated by the infrared radiation layer 35 towards the atomizing cavity 311 passes through the light-transmitting ceramic tube into the atomizing cavity 311, while the other portion enters the atomizing cavity 311 through perforations. At least a portion of the infrared light radiated by the infrared radiation layer 35 towards the reflector is reflected by the reflector. Of the reflected infrared light, a portion passes through the light-transmitting ceramic tube into the atomizing cavity 311, while the other portion enters the atomizing cavity 311 through perforations. In the aforementioned infrared light transmission process, the perforations allow the infrared light to easily enter the atomizing cavity 311, resulting in less light loss and thus higher energy utilization of the infrared radiation.

[0141] In another embodiment, the infrared radiation layer 35 is disposed on the inner side of the sidewall of the heating element 31. If the heating element 31 is a light-transmitting ceramic tube, at least part of the infrared light radiated by the infrared radiation layer 35 toward the reflector passes through the light-transmitting ceramic tube and is reflected by the reflector. Of the reflected infrared light, a portion passes through the light-transmitting ceramic tube and enters the atomization cavity 311, while the other portion enters the atomization cavity 311 through a perforation. Similarly, in the above-mentioned infrared light transmission process, the perforation allows the infrared light to easily enter the atomization cavity 311, resulting in less light loss and thus higher energy utilization of infrared radiation.

[0142] Furthermore, the more perforations there are, the more infrared light enters the atomization chamber 311. Therefore, the perforation arrangement increases the proportion of infrared light that can ultimately enter the atomization chamber 311 relative to the initial infrared light radiated by the infrared radiation layer 35, reduces the energy loss of the heating structure 100, improves the energy utilization rate of the heating component 30, generates more aerosol for the user to inhale, and produces a better-tasting aerosol, resulting in a better user experience.

[0143] Please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 Secondly, this application provides a heating structure 100. The heating structure 100 includes a support 10 and a heating component 30 as described in any of the above embodiments. The support 10 has a receiving cavity 11, an inlet 131, and an outlet 1511, with the inlet 131 and outlet 1511 located at opposite ends of the receiving cavity 11. The heating component 30 is housed within the receiving cavity 11, and the opposite ends of the atomizing cavity 311 are respectively connected to the inlet 131 and outlet 1511.

[0144] Specifically, the support 10 is a structure in the heating structure 100 used to house components other than the support 10. Components other than the support 10 in this document include, but are not limited to, the heating element 30. The shape of the outer contour of the cross-section of the support 10 obtained by a plane perpendicular to the length direction Z of the heating element 30 can be regular or irregular. Regular shapes in this document include, but are not limited to, rectangles, circles, ellipses, triangles, and rectangles. The accommodating cavity 11 is a spatial structure in the heating structure 100 used to house at least some of the components other than the support 10. The shape of the accommodating cavity 11 corresponds to the outer contour shape of the support 10.

[0145] The heating element 30 is housed within the receiving cavity 11. The connection between the bracket 10 and the heating element 30 can be either detachable or non-detachable. Detachable connections include, but are not limited to, one or more combinations of methods such as abutment, screw connection, and snap-fit ​​connection. Non-detachable connections include, but are not limited to, one or more combinations of methods such as gluing, welding, and sintering. This definition will be used for both detachable and non-detachable connections in the future and will not be elaborated further.

[0146] Inlet 131 is a spatial structure that provides a channel for external gas to enter the containment cavity 11, and outlet 1511 is a spatial structure that provides a channel for substances (such as generated aerosols) in the containment cavity 11 to flow to the outside. Inlet 131 and outlet 1511 are located at opposite ends of the containment cavity 11, so that the containment cavity 11 can allow substances to flow in or out smoothly. Atomizing cavity 311 is a spatial structure with open ends, and these two ends are connected to inlet 131 and outlet 1511 respectively, so that at least a portion of the aerosol generating matrix 20 extends into the atomizing cavity 311, and the atomizing cavity 311 can allow gas to flow in or out. After the aerosol generating matrix 20 is loaded into the atomizing cavity 311, it can be heated by heating element 30 to generate aerosols.

[0147] In the heating structure 100 of this application, at least two heating units 310 and a separator 32 are alternately distributed along the length Z of the heating component 30, forming an atomization chamber 311 open at both ends. When the aerosol generating matrix 20 is housed in the atomization chamber 311, the heating energy of each heating unit 310 can be individually controlled to heat the aerosol generating matrix 20 in sections. At this time, the separator 32 can prevent heat transfer between adjacent heating units 310, and there will be no cross-temperature problem in the section heating process of the aerosol generating matrix 20. The heating component 30 can accurately control the temperature of each section of the aerosol generating matrix 20, resulting in fast heating rate, sufficient aerosol volume in the first puff, high consistency of aerosol taste in each puff, and low energy consumption.

[0148] Please refer to Figure 1 , Figure 5 and Figure 6 The heating structure 100 also includes an aerosol generating matrix 20, which passes through the receiving cavity 11, and at least a portion of the medium segment 21 of the aerosol generating matrix 20 is housed in the atomizing cavity 311. In the length direction Z, the side of the medium segment 21 near the first end 301 of the heating element extends beyond the top edge of the upper heating unit 3101 near the first end 301 of the heating element in at least two heating units 310, and the side of the medium segment 21 near the second end 303 of the heating element extends beyond the bottom edge of the lower heating unit 3103 near the second end 303 of the heating element in the heating unit 310.

[0149] Specifically, in the above embodiments, the aerosol generating matrix 20 is part of the heating structure 100. In some embodiments, the aerosol generating matrix 20 inserted into the heating structure 100 can be replaced, and the heating structure 100 can be reused. In other embodiments, the aerosol generating matrix 20 inserted into the heating structure 100 cannot be replaced, and the heating structure 100 and the aerosol generating matrix 20 together are disposable products.

[0150] When the aerosol generating matrix 20 is inserted into the heating structure 100, the aerosol generating matrix 20 passes through the receiving cavity 11 and extends at least partially into the atomization cavity 311. The portion of the aerosol generating matrix 20 extending into the atomization cavity 311 includes at least a portion of the medium segment 21, so that the heating component 30 can heat at least the medium segment 21 of the aerosol generating matrix 20 and generate aerosol. At this time, in the length direction Z, at least a portion of the medium segment 21 on the side near the first end 301 of the heating component protrudes from the top edge of the upper heating unit 3101 near the first end 301 of the heating component in at least two heating units 310. Therefore, during the heating of the medium segment 21 by the upper heating unit 3101, at least a portion of the heat is transferred in the medium segment 21 to the side of the medium segment 21 near the first end 301 of the heating component. At this time, the segment can be heated by heat transfer, and the amount of aerosol generated is relatively large. At least a portion of the medium segment 21 protrudes from the bottom edge of the lower heating unit 3103 near the second end 303 of the heating component in the heating unit 310. Therefore, during the process of the lower heating unit 3103 heating the medium segment 21, at least a portion of the heat is transferred in the medium segment 21 to the side of the medium segment 21 near the second end 303 of the heating component. At this time, the segment can be heated by heat transfer, and the amount of aerosol generated is relatively large.

[0151] Therefore, when the medium segment 21 extends beyond the top edge of the first end 301 of the upper heating unit 3101 near the heating component and the bottom edge of the second end 303 of the lower heating unit 3103 near the heating component, the relative positional relationship between the medium segment 21 and the heating component 30 is well matched. During the heating process, the heat of the heating element 31 is indirectly transferred to the extended part of the medium segment 21 through heat transfer, resulting in a large amount of aerosol generated and low energy consumption of the heating structure 100.

[0152] Please refer to Figure 7 Thirdly, this application provides an aerosol generating apparatus 1000. The aerosol generating apparatus 1000 includes a battery assembly 300 and a heating structure 100 as described in any of the above embodiments, wherein the heating structure 100 is electrically connected to the battery assembly 300.

[0153] Specifically, in the above practical method, it should be noted that the specific structure and properties of the heating structure 100 in this embodiment are exactly the same as those in the above embodiments, and will not be explained again here. The aerosol generating device 1000 is a structure capable of generating aerosols by heating the aerosol generating matrix 20. The battery assembly 300 is used to provide electrical energy to the electrically powered components (e.g., the heating structure 100) in the aerosol generating device 1000, enabling the heating structure 100 to heat the atomized aerosol generating matrix 20 to form an aerosol. For example, when the aerosol generating device 1000 is aspirated, the battery assembly 300 supplies power to the heating structure 100; in this case, the heating structure 100 heats the aerosol generating matrix 20 and generates aerosols. When the user does not aspirate the aerosol generating device 1000, the battery assembly 300 stops supplying power to the heating structure 100; in this case, the heating structure 100 does not heat the aerosol generating matrix 20. It should be noted that, in some embodiments, the battery assembly 300 can be a dry cell battery or a rechargeable battery. Rechargeable batteries include, but are not limited to, lithium-ion batteries, nickel-metal hydride batteries, and nickel-cadmium batteries.

[0154] In the aerosol generating apparatus 1000 of this application, at least two heating units 310 and separators 32 are alternately distributed along the length Z of the heating structure 100, forming an atomization chamber 311 open at both ends. When the aerosol generating matrix 20 is housed in the atomization chamber 311, the heating energy of each heating unit 310 can be individually controlled to heat the aerosol generating matrix 20 in sections. At this time, the separators 32 can prevent heat transfer between adjacent heating units 310, and there will be no cross-temperature problem in the section heating process of the aerosol generating matrix 20. The heating components 30 can accurately control the temperature of each section of the aerosol generating matrix 20, resulting in fast heating rate, sufficient aerosol quantity in the first puff, high consistency of aerosol taste in each puff, and low energy consumption.

[0155] The technical features of the embodiments described above can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. Furthermore, other implementation methods can be derived from the above embodiments, allowing for structural and logical substitutions and changes without departing from the scope of this disclosure.

[0156] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
