Description

Technical Field

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

[0002] The aerosol generating device heats the aerosol generating matrix using a heating component, causing it to atomize and generate aerosols for inhalation. Specifically, the aerosol generating matrix extends into an atomization chamber surrounded by a heating element. A heating wire in the heating component surrounds the heating element and is energized to generate heat, exciting the infrared radiation layer and radiating energy into the atomization chamber of the heating element, thereby atomizing the aerosol generating matrix to produce aerosols. During the process of the heating wire being energized and generating heat, because the electrical excitation frequency of the heating wire is close to its natural frequency, the heating wire may resonate, causing noise in the aerosol generating device. Utility Model Content

[0003] This application provides a heating component and an aerosol generating device.

[0004] In a first aspect, this application provides a heating assembly. The heating assembly includes an annular reflector, a heating element, a heating wire, and a connector. The heating element is housed within the reflector. The heating wire is arranged around the sidewall of the heating element and configured to generate heat when energized. The reflector is used to reflect at least the heat generated by the heating wire. The connector is disposed between the heating wire and the reflector. One end of the connector is connected to the inner wall of the reflector, and the other end is connected to the heating wire.

[0005] In some embodiments, the heating wire includes at least one heating segment. The heating segments are arranged sequentially at intervals in a first direction parallel to the axis of the heating element. Each heating segment is connected to the connector.

[0006] In some embodiments, the connectors include at least two. The connectors are respectively connected to the beginning and end of the heating segment along its extension direction.

[0007] In some embodiments, the heating segment encircles the heating element two or more times, and the first and last turns of the heating segment are each connected to at least two of the connecting members.

[0008] In some embodiments, in a projection plane perpendicular to the first direction, the connectors connected to the first ring are spaced apart from each other and evenly distributed in the circumferential direction of the heating element.

[0009] In some embodiments, in a projection plane perpendicular to the first direction, the connectors connected to the last ring are spaced apart from each other and evenly distributed in the circumferential direction of the heating element.

[0010] In some embodiments, the beginning and end of the heating segment are offset in a projection plane perpendicular to the first direction.

[0011] In some embodiments, the heating assembly further includes a damping layer, which is disposed at least on the surface where the heating wire is connected to the connector.

[0012] In some embodiments, the heating assembly further includes a damping layer, which is disposed at least on the surface where the connector is connected to the heating wire.

[0013] In some embodiments, the connector has a support area connected to the lower surface of the heating wire to support the heating wire. In the circumferential direction of the heating wire, the average size of the support area is greater than or equal to 0.6 mm and less than or equal to 0.8 mm.

[0014] In some embodiments, the heating assembly further includes a support and a conductive element. The support has a receiving cavity, an inlet, and an outlet, the inlet and outlet being located at opposite ends of the receiving cavity. The heating element is housed within the receiving cavity, and the sidewalls of the heating element form an atomizing cavity open at both ends and communicating with the inlet and the outlet, respectively. The atomizing cavity is configured to house an aerosol generating matrix. The conductive element is connected to the heating wire. The outer surface of the heating wire has an infrared radiation layer, and the heating wire is configured to generate heat through the conductive element and transfer the heat to the infrared radiation layer to radiate infrared light. The infrared light passes through the heating element and enters the atomizing cavity to heat the aerosol generating matrix. A reflector is housed within the receiving cavity and positioned between the heating element and the support. The reflector also reflects the infrared light emitted by the infrared radiation layer. At least a portion of the outer periphery of the conductive element is fitted with a sleeve, the sleeve passing through the support.

[0015] In some embodiments, the heating assembly further includes a sealing assembly. The sealing assembly is sandwiched between the support and the heating element, and is configured to seal the gap between the heating element and the support.

[0016] Secondly, this application provides an aerosol generating apparatus. The aerosol generating apparatus includes a battery assembly and a heating assembly as described in any of the above embodiments, wherein the heating wire is electrically connected to the battery assembly.

[0017] In the heating assembly and aerosol generating device of this application, both the heating element and the heating wire are housed in an annular reflector, with the heating wire surrounding the side wall of the heating element. When the heating wire is energized and generates heat, the heat directly or indirectly heats the aerosol generating matrix and produces aerosols. The reflector reflects the heat generated by the heating wire, improving energy utilization. Connectors are respectively connected to the inner walls of the heating wire and the reflector to support the heating wire. Because the connectors establish a connection between the heating wire and the reflector, the natural frequency of the heating wire increases and differs significantly from the electrical excitation frequency. This makes it less likely for the heating wire to resonate, and the aerosol generating device will not generate noise during operation.

[0026] An aerosol generating device heats an aerosol generating matrix using a heating component, causing the matrix to atomize and generate aerosols for inhalation. Specifically, the aerosol generating matrix extends into an atomization chamber surrounded by a heating element. A heating wire in the heating component surrounds the heating element and is energized to generate heat, exciting the infrared radiation layer and radiating energy into the atomization chamber of the heating element, thereby atomizing the aerosol generating matrix to produce aerosols. During the process of the heating wire being energized and generating heat, the heating wire may resonate because the electrical excitation frequency is close to its natural frequency, causing noise in the aerosol generating device. To address this issue, this application provides a heating component 100 (… Figures 1 to 3 ,and Figure 7 (as shown) and aerosol generating device 1000 ( Figure 8 (As shown).

[0027] Please refer to this as well. Figures 1 to 4 In a first aspect, this application provides a heating assembly 100. The heating assembly 100 includes an annular reflector 10, a heating element 20, a heating wire 30, and a connector 40. The heating element 20 is housed within the reflector 10. The heating wire 30 is disposed around the sidewall of the heating element 20 and configured to generate heat when energized. The reflector 10 is used to reflect at least the heat generated by the heating wire 30. The connector 40 is disposed between the heating wire 30 and the reflector 10. One end of the connector 40 is connected to the inner wall of the reflector 10, and the other end is connected to the heating wire 30.

[0028] Specifically, the aerosol generating apparatus 1000 is a device that loads an aerosol generating matrix and heats it to generate aerosols. The aerosol generating matrix 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 can be in liquid or solid form (including fully solid and semi-solid). In the embodiments of this application, the aerosol generating matrix is ​​a long strip-shaped solid, which is inserted into the heating component 100 of the aerosol generating apparatus 100 for heating during use.

[0029] A heating component 100 is a structure used to heat an object to be heated, so that it is at least partially heated and its temperature rises. In this application, the heating component 100 is a structure used to heat an aerosol-generating matrix to generate aerosols. The heating component 100 can employ different heating methods to heat the aerosol-generating matrix, and correspondingly, the heating component 100 includes different structures. In some embodiments, when the heating component 100 uses electromagnetic waves to heat the aerosol-generating matrix, the heating component 100 includes an electromagnetic coil that can radiate electromagnetic waves to heat the aerosol-generating matrix and generate aerosols. In other embodiments, when the heating component 100 uses microwaves to heat the aerosol-generating matrix, the heating component 100 includes a microwave generator that can radiate microwaves to heat the aerosol-generating matrix and generate aerosols. In still other embodiments, when the heating component 100 uses lasers to heat the aerosol-generating matrix, the heating component 100 includes a laser emitter that can emit laser light to heat the aerosol-generating matrix and generate aerosols. In some embodiments, when the heating assembly 100 uses infrared light to heat the aerosol generation matrix, the heating assembly 100 includes a heating element 20, a heating wire 30, and an infrared radiation layer. The heat generated by the heating wire 30 causes the infrared radiation layer to emit infrared light, thereby heating the aerosol generation matrix to generate aerosols. This application uses the heating assembly 100 using infrared light to heat the aerosol generation matrix as an example.

[0030] The heating element 20 has an open structure at both ends, and the structure formed by the side walls of the heating element 20 is an atomizing cavity 21. The atomizing cavity 21 is a spatial structure with open ends, so that at least a portion of the aerosol generating matrix extends into the atomizing cavity 21, and the atomizing cavity 21 can allow gas to flow in or out. In some embodiments, the heating element 20 is light-transmitting, in which case light from outside the atomizing cavity 21, such as infrared light, can pass through the heating element 20 and enter the atomizing cavity 21.

[0031] The heating wire 30 is a component in the heating assembly 100 that generates heat and transfers at least a portion of the heat to the surrounding area. The heating wire 30 may be made of at least one of the following materials with appropriate resistance: 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 alloy materials 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. The heating wire 30 is disposed around the outer sidewall of the heating element 20 to fully cover the atomizing cavity 21. When energized through its connection with the connector 40 and the conductive element 60, the heating wire 30 generates heat and transfers it to the structure it contacts and radiates it to at least a portion of the space surrounding the heating wire 30.

[0032] The heating assembly 100 also includes an infrared radiation layer (not shown), which radiates infrared light upon excitation by heat. The material of the infrared radiation layer may include, but is not limited to, chromium oxide, zirconium oxide, iron oxide, and graphene. The infrared radiation layer is located on at least one of the outer surface of the heating element 20, the inner surface of the heating element 20, and the surface of the heating wire 30. When the heating wire 30 is energized and generates heat, at least a portion of the heat generated by the heating wire 30 is transferred to the infrared radiation layer. The infrared radiation layer receives the heat and radiates infrared light. The infrared light passes through the heating element 20 and enters the atomization chamber 21. At this time, the infrared light can use its carried energy to heat the aerosol generation matrix to generate aerosols. The heat provided by the heating wire 30 to the infrared radiation layer includes the heat directly transferred from the heating wire 30 to the infrared radiation layer and the heat generated by the heating wire 30 indirectly transferred to the infrared radiation layer through other structures (such as air and the heating element 20).

[0033] The reflector 10 is a structure in the heating assembly 100 used to reflect the heat generated by the heating wire 30. The heating element 20 is housed in the reflector 10, that is, the reflector 10 surrounds the heating element 20 and the heating wire 30. In this application, the direction of the axis of the heating element 20 is defined as the first direction Z. At this time, when the heat generated by the heating wire 30 is transferred to the outside of the atomizing cavity 21 in a direction perpendicular to the first direction Z, the reflector 10 can block the heat transfer. At this time, the infrared radiation layer can receive more heat and can radiate stronger infrared light to the aerosol generation matrix. At this time, the energy utilization rate of the heating assembly 100 is higher.

[0034] The connector 40 is a structure used to increase the natural frequency of the heating wire 30. Because the heating wire 30 is only connected to the heating body 20 by an interference fit, tightly wrapped around the side wall of the heating body 20, and because the heating wire 30 has a small diameter but a large length, its overall shape is approximately a long, thin strip, resulting in a low natural frequency. During the process of the heating wire 30 being energized and generating heat, the frequency of the electrical excitation experienced by the heating wire 30 is close to its natural frequency, making it prone to resonance and noise. With the connector 40 connecting the heating wire 30 and the reflector 10, the fixing method of the heating wire 30 is optimized, the constraint on the heating wire 30 is increased, and at least one of the types, ranges, and amplitudes of vibrations that the heating wire 30 can undergo is limited. Therefore, the natural frequency of the heating wire 30 increases and becomes greater than the frequency of the electrical excitation experienced by the heating wire 30, making it less prone to resonance.

[0035] Specifically, one end of the connector 40 is connected to the inner wall of the reflector 10. The connector 40 and the reflector 10 can be an integral structure or separate structures. When the connector 40 and the reflector 10 are separate structures, the connection between the connector 40 and the reflector 10 can be either detachable or non-detachable. Detachable connections include, but are not limited to, one or more combinations of screw connections and snap-fit ​​connections. Non-detachable connections include, but are not limited to, one or more combinations of gluing, welding, and sintering methods. This definition will be used for both detachable and non-detachable connections in the future. The other end of the connector 40 is connected to the heating wire 30. The connector 40 and the heating wire 30 can be either abutting or fixedly connected. When the connector 40 and the heating wire 30 are fixedly connected, the connection between the connector 40 and the heating wire 30 can be either detachable or non-detachable.

[0036] In the heating assembly 100 of this application, both the heating element 20 and the heating wire 30 are housed in an annular reflector 10, and the heating wire 30 is arranged around the side wall of the heating element 20. When the heating wire 30 is energized and generates heat, the heat heats the aerosol generation matrix directly or indirectly and generates aerosol. At this time, the reflector 10 can reflect the heat generated by the heating wire 30 to improve energy utilization. The connector 40 is connected to both the heating wire 30 and the inner wall of the reflector 10 to support the heating wire 30. At this time, since the connector 40 establishes a connection between the heating wire 30 and the reflector 10, the natural frequency of the heating wire 30 increases and has a large difference from the electrical excitation frequency received by the heating wire 30. At this time, the heating wire 30 is less likely to resonate, and the aerosol generation device 1000 will not generate noise during use.

[0037] Please refer to Figures 2 to 5In some embodiments, the heating wire 30 includes at least one heating segment 31. The heating segments 31 are arranged sequentially at intervals along a first direction Z parallel to the axis of the heating element 20. Each heating segment 31 is connected to a connector 40.

[0038] Specifically, the heating segment 31 is the smallest heating unit in the heating wire 30 used to generate heat. In the first direction Z, the heating segments 31 are sequentially distributed and respectively arranged around the sidewall of the heating element 20, with each heating segment 31 spaced apart from the others. It can be understood that the range covered by all the heating segments 31 in the first direction Z determines the range within which the heating assembly 100 can heat the aerosol generating matrix. In some embodiments, each heating segment 31 can be controlled independently to perform a more flexible and targeted heating of the aerosol generating matrix.

[0039] Please refer to Figure 2 and Figure 3 This application uses three heating wires 30 as an example. During the operation of the heating assembly 100, each heating segment 31 is energized and generates heat. To avoid resonance in any heating segment 31, each heating segment 31 is provided with a corresponding connector 40. At this time, one end of the connector 40 is connected to the inner wall of the reflector 10, and the other end is connected to the corresponding heating segment 31. It should be noted that since the structure and properties of each heating segment 31 are approximately the same, this application only uses the heating segment 31 closest to the outlet 55 (described below) as an example for illustration, and the illustration also only shows the connector 40 corresponding to the heating segment 31 closest to the outlet 55. The structure and properties of other heating segments 31 are the same as those described in this application and will not be described in detail here.

[0040] Therefore, in the heating assembly 100 of this application, the heating segments 31 are arranged sequentially at intervals in the first direction Z and can cooperate with each other to heat the aerosol generation matrix. Each heating segment 31 is connected to the inner wall of the reflector 10 via a connector 40. At this time, since the connector 40 establishes a connection between each heating segment 31 and the reflector 10, the natural frequency of the heating wire 30 increases and has a large difference from the electrical excitation frequency received by the heating wire 30. At this time, the heating wire 30 is less likely to resonate, and the aerosol generation device 1000 will not generate noise during use.

[0041] Please refer to Figures 4 to 6 In some embodiments, the connector 40 includes at least two connectors. Connectors 40 are respectively connected to the beginning and end of the heating segment 31 in the extending direction of the heating segment 31.

[0042] Specifically, in the above embodiments, it can be understood that the more connectors 40 there are, the greater the degree to which the heating segment 31 is constrained, the higher the natural frequency of the heating segment 31, and the less likely the heating wire 30 is to resonate. The number of connectors 40 is at least two, so that the connectors 40 can connect at least the first and last ends of each heating segment 31 to the reflector 10. At this time, both ends of each heating segment 31 are constrained, and the resistance to deformation of each heating segment 31 is enhanced. At least one of the types, ranges, and amplitudes of vibrations that the heating wire 30 can undergo is limited. The natural frequency of the heating wire 30 increases and is greater than the frequency of the electrical excitation received by the heating wire 30. The heating wire 30 is less likely to resonate, and the aerosol generating device 1000 will not generate noise during use.

[0043] It should be noted that the number of connectors 40 cannot be increased indefinitely. If the number of connectors 40 is too large, the fixing range between the heating wire 30 and the connectors 40 will be too large. A large part of the heat generated by the heating wire 30 will be transferred to the reflector 10 through the connectors 40 and will not be effectively radiated to the infrared radiation layer. At this time, the aerosol generation matrix may not be fully heated, resulting in a poor taste of the generated aerosol and wasting energy.

[0044] Please refer to Figures 4 to 6 In some embodiments, the heating segment 31 surrounds the heating element 20 in two or more turns, and the first turn 311 and the last turn 313 of the heating segment 31 are respectively connected to at least two connectors 40.

[0045] Specifically, when the number of turns of the heating segment 31 around the heating element 20 is greater than or equal to two, the extension length of the heating segment 31 is relatively large, the heating segment 31 has a low natural frequency, and is prone to resonance. Therefore, in the heating assembly 100 of this application, the turn of the heating segment 31 closest to the outlet 55 is designated as the first turn 311, and the turn of the heating segment 31 furthest from the outlet 55 is designated as the last turn 313. It can be understood that the first turn 311 and the last turn 313 are connected when the number of turns of the heating segment 31 around the heating element 20 is two, and are spaced apart and indirectly connected when the number of turns of the heating segment 31 around the heating element 20 is greater than two.

[0046] With at least two connectors 40 connected to the first ring 311 and the last ring 313 respectively, the first end of the heating segment 31 in the first ring 311 is connected to at least one other position at a certain distance from the first end by a connector 40, and the tail end of the heating segment 31 in the last ring 313 is connected to at least one other position at a certain distance from the tail end by a connector 40. At this time, while the two ends of each heating segment 31 are constrained, there are other constrained areas. Each heating segment 31 is equivalent to being further divided into small "sub-regions". The vibration-generating section is further restricted, and the deformation resistance of each heating segment 31 is further enhanced. At least one of the types, ranges and amplitudes of vibrations that the heating wire 30 can undergo is further restricted. The natural frequency of the heating wire 30 is further increased and is significantly greater than the frequency of the electrical excitation frequency received by the heating wire 30. The heating wire 30 is less likely to resonate, and the aerosol generating device 1000 will not generate noise during use.

[0047] In some examples, in the projection plane perpendicular to the first direction Z, the connectors 40 connected to the first ring 311 are spaced apart from each other and evenly distributed in the circumferential direction of the heating element 20.

[0048] For details, please refer to Figure 5 and combined Figure 6 This application uses three connectors 40 connected to the first ring 311 as an example, and names the three connectors 40 corresponding to the first ring 311 as connector 40 (A1), connector 40 (A2), and connector 40 (A3), respectively. Taking the plane perpendicular to the first direction Z as the projection plane, in the projection plane, connectors 40 (A1), connectors 40 (A2), and connectors 40 (A3) are spaced apart from each other and evenly distributed in the circumferential direction of the heating element 20. At this time, the angle difference between any two connectors 40 (A1), connectors 40 (A2), and connectors 40 (A3) is 120 degrees.

[0049] At this time, each connector 40 forms a stable triangular support structure with the first ring 311. The effective stiffness of the system consisting of the heating wire 30, connector 40 and reflector 10 is uniform and highest in all radial directions. Each heating segment 31 is fully constrained and subjected to uniform force. Each heating segment 31 has extremely strong resistance to deformation. At least one of the types, ranges and amplitudes of vibrations that the heating wire 30 can undergo is effectively limited. The natural frequency of the heating wire 30 is sufficiently increased and is significantly greater than the frequency of the electrical excitation frequency of the heating wire 30. The heating wire 30 is not prone to resonance. The aerosol generating device 1000 will not generate noise during use.

[0050] In other examples, in the projection plane perpendicular to the first direction Z, the connectors 40 connected to the last ring 313 are spaced apart from each other and evenly distributed in the circumferential direction of the heating element 20.

[0051] For details, please refer to Figure 5 and combined Figure 6 This application uses three connectors 40 connected to the last ring 313 as an example, and names the three connectors 40 corresponding to the last ring 313 as connector 40 (B1), connector 40 (B2), and connector 40 (B3), respectively. Taking the plane perpendicular to the first direction Z as the projection plane, in the projection plane, connectors 40 (B1), connector 40 (B2), and connector 40 (B3) are spaced apart from each other and evenly distributed in the circumferential direction of the heating element 20. At this time, the angle difference between any two connectors 40 (B1), connector 40 (B2), and connector 40 (B3) is 120 degrees.

[0052] At this time, each connector 40 forms a stable triangular support structure with the last coil 313. The effective stiffness of the system consisting of the heating wire 30, connector 40 and reflector 10 is uniform and highest in all radial directions. Each heating segment 31 is fully constrained and subjected to uniform force. Each heating segment 31 has extremely strong resistance to deformation. At least one of the types, ranges and amplitudes of vibrations that the heating wire 30 can undergo is effectively limited. The natural frequency of the heating wire 30 is sufficiently increased and is significantly greater than the frequency of the electrical excitation frequency of the heating wire 30. The heating wire 30 is not prone to resonance. The aerosol generating device 1000 will not generate noise during use.

[0053] Please refer to Figures 3 to 5 In some embodiments, the beginning and end of the heating segment 31 are offset in the projection plane perpendicular to the first direction Z.

[0054] Specifically, in each heating segment 31, the heating segment 31 is electrically excited and generates energy waves. The energy waves propagate in the heating segment 31, and after circling once, they are reflected at the tail end and propagate in the opposite direction. When the phase of the energy wave is exactly the same as the phase of the next newly generated energy wave (i.e., "in phase"), the reflected energy wave will coherently superimpose with the next newly generated energy wave, and the energy will continuously increase and form a strong standing wave. At this time, the heating segment 31 will resonate.

[0055] Using a plane perpendicular to the first direction Z as the projection plane, the beginning and end of the heating segment 31 are offset within the projection plane, meaning the number of turns of the heating segment 31 is not an integer. At this time, the newly generated energy wave and the reflected energy wave meet and superimpose within the heating segment 31. Due to the asymmetry of the structure of the heating segment 31, the newly generated energy wave and the reflected energy wave will have a phase difference at most positions and frequencies. At this time, the newly generated energy wave and the reflected energy wave weaken each other, that is, the resonance peak is split, the heating wire 30 is less likely to resonate, and the aerosol generating device 1000 will not generate noise during use.

[0056] Please refer to Figures 4 to 6 In some embodiments, the heating assembly 100 further includes a damping layer. Specifically, the damping layer (not shown) is a structure used to enhance the damping of two elements in contact with each other. Exemplarily, the damping layer may be, but is not limited to, one or more of the following: a metal-rubber layer, a porous ceramic coating, an intermetallic compound composite coating, or a metal composite coating.

[0057] In some examples, a damping layer is provided at least on the surface where the heating wire 30 connects to the connector 40. In this case, due to the presence of the damping layer, the surface roughness of the surface where the heating wire 30 connects to the connector 40 increases, the damping between the heating wire 30 and the connector 40 increases, the connector 40 can constrain the heating wire 30, the natural frequency of the heating wire 30 further increases, the heating wire 30 is less prone to resonance, and the aerosol generating device 1000 will not generate noise during use.

[0058] In other examples, a damping layer is provided at least on the surface where the connector 40 connects to the heating wire 30. In this case, due to the presence of the damping layer, the surface roughness of the surface where the connector 40 connects to the heating wire 30 increases, the damping between the heating wire 30 and the connector 40 increases, the connector 40 can constrain the heating wire 30, the natural frequency of the heating wire 30 further increases, the heating wire 30 is less prone to resonance, and the aerosol generating device 1000 will not generate noise during use.

[0059] It is understandable that when the damping layer is simultaneously provided on the surface where the heating wire 30 and the connector 40 are connected, and on the surface where the connector 40 and the heating wire 30 are connected, the surface roughness of both the surface where the heating wire 30 and the connector 40 are connected increases. The damping between the heating wire 30 and the connector 40 is greater, the connector 40 can better constrain the heating wire 30, the natural frequency of the heating wire 30 is greatly increased, the heating wire 30 is less likely to resonate, and the aerosol generating device 1000 will not generate noise during use.

[0060] Please refer to Figures 4 to 6 In some embodiments, the connector 40 is provided with a support area 41, which is connected to the lower surface of the heating wire 30 to support the heating wire 30. In the circumferential direction of the heating wire 30, the average size of the support area 41 is greater than or equal to 0.6 mm and less than or equal to 0.8 mm.

[0061] Specifically, the support area 41 is the area on the connector 40 used for connecting with the heating wire 30. Based on the conventional use direction of the heating assembly 100 (outlet 55 facing upwards), when the support area 41 is connected to the heating wire 30 (heating segment 31), the lower surface of the heating wire 30 abuts against and connects with the support area 41, at which time the connector 40 can support the heating wire 30.

[0062] Since one end of the connector 40 is connected to the reflector 10 and the other end is connected to the heating wire 30, the extending direction of the connector 40 forms a certain angle with the circumferential direction of the heating wire 30. In the circumferential direction of the heating wire 30, the average size of the supporting area 41 determines the size of the area where the connector 40 can support the heating wire 30, that is, the degree to which the heating wire 30 is constrained. Please refer to... Figure 6 In the circumferential direction of the heating wire 30, the average value of the size of the support area 41 is obtained by the average value of the sizes X1, X2, X3, X4, X5 and X6 of each support area 41.

[0063] The average value of the dimensions of the support area 41 can be, but is not limited to, any one or any two of the following: 0.6mm, 0.62mm, 0.64mm, 0.66mm, 0.68mm, 0.7mm, 0.72mm, 0.74mm, 0.76mm, and 0.8mm. If the average value of the dimensions of the support area 41 is less than 0.6mm, then the dimensions of the support area 41 are too small. In this case, the fixing range between the connector 40 and the heating wire 30 is too small, the heating wire 30 is not sufficiently constrained, the natural frequency of the heating wire 30 may still be low, and the heating wire 30 may resonate. If the average size of the support area 41 is greater than 0.8 mm, then the size of the support area 41 is too large. In this case, the fixing range between the heating wire 30 and the connector 40 is too large, and a large part of the heat generated by the heating wire 30 will be transferred to the reflector 10 through the connector 40 instead of being effectively radiated to the infrared radiation layer. At this time, the aerosol generating matrix may not be fully heated, resulting in a poor taste of the generated aerosol and wasting energy. Therefore, the average size of the support area 41 is within the range mentioned above. This ensures that the heating wire 30 is sufficiently constrained, its natural frequency is high and it is not easy for it to resonate, and it also avoids excessive heat transfer from the heating wire 30 to the connector 40. This results in higher energy utilization of the heating component 100, and the aerosol generating matrix can be fully heated, leading to a better taste of the generated aerosol.

[0064] Please refer to Figures 1 to 3 ,and Figure 7In some embodiments, the heating assembly 100 further includes a support 50 and a conductive element 60. The support 50 has a receiving cavity 51, an inlet 53, and an outlet 55, with the inlet 53 and outlet 55 located at opposite ends of the receiving cavity 51. The heating element 20 is housed within the receiving cavity 51, and the sidewalls of the heating element 20 form an atomizing cavity 21, which is open at both ends and communicates with the inlet 53 and outlet 55 respectively. The atomizing cavity 21 is configured to house the aerosol generating matrix. A reflector 10 is housed within the receiving cavity 51 and positioned between the heating element 20 and the support 50. The reflector 10 also reflects infrared light emitted by the infrared radiation layer. The conductive element 60 is connected to the heating wire 30. The outer surface of the heating wire 30 is provided with an infrared radiation layer. The heating wire 30 is configured to generate heat through the conductive element 60 and transfer the heat to the infrared radiation layer so that the infrared radiation layer radiates infrared light. The infrared light passes through the heating element 20 and enters the atomizing cavity 21 to heat the aerosol generating matrix. At least a portion of the outer periphery of the conductive element 60 is fitted with a sleeve 70, and the sleeve 70 passes through the bracket 50.

[0065] Specifically, the bracket 50 is a structure in the heating assembly 100 used to mount components other than the bracket 50. Components other than the bracket 50, as used herein, include, but are not limited to, the heating element 20, the reflector 10, the heating wire 30, and the sealing assembly 80, which will be mentioned below. The shape of the outer contour of the cross-section of the bracket 50 obtained by a plane perpendicular to the first direction Z can be a regular shape or an irregular shape. Regular shapes, as used herein, include, but are not limited to, rectangles, circles, ellipses, triangles, and rectangles.

[0066] The receiving cavity 51 is a spatial structure in the heating assembly 100 used to house at least some of the components other than the bracket 50. The shape of the receiving cavity 51 corresponds to the inner contour shape of the bracket 50. Furthermore, the connections between the bracket 50 and the heating element 20, between the bracket 50 and the sealing assembly 80, and between the bracket 50 and the reflector 10 can be either detachable or non-detachable. The heating element 20 is housed within the receiving cavity 51, and the bracket 50 provides support and protection for the installation of the heating element 20.

[0067] Inlet 53 is a spatial structure that provides a channel for external gas to enter the atomizing chamber 21, and outlet 55 is a spatial structure that provides a channel for substances (such as generated aerosols) in the containing chamber 51 to flow to the outside. Inlet 53 and outlet 55 are located at opposite ends of the containing chamber 51 to allow substances to flow smoothly in or out of the containing chamber 51. During the loading of the aerosol generating matrix into the atomizing chamber 21, the aerosol generating matrix is ​​inserted into the atomizing chamber 21 through outlet 55 and extends at least partially into the atomizing chamber 21. At this time, the heating component 100 can heat it to generate aerosols.

[0068] The conductive element 60 is a structure used to electrically connect the heating wire 30 to the external power supply circuit. The conductive element 60 can be, but is not limited to, a wire, a flexible circuit board, or a metal sheet. This application uses the conductive element 60 as a wire as an example. Please refer to the figures. The conductive element 60 is deformable to allow for more flexible layout and to avoid other structures. Furthermore, in some embodiments, the outer surface of the heating wire 30 is provided with an infrared radiation layer. The heating wire 30 is configured to generate heat through the conductive element 60 and transfer the heat to the infrared radiation layer so that the infrared radiation layer radiates infrared light. The infrared light passes through the heating element 20 and enters the atomization chamber 21 to heat the aerosol to generate a matrix.

[0069] It should be noted that the specific structure and properties of the infrared radiation layer in this embodiment are exactly the same as those in the above embodiments, and will not be explained again here. The infrared radiation layer is disposed on the surface of the heating wire 30. When the heating wire 30 is energized and generates heat, at least a portion of the heat generated by the heating wire 30 is transferred to the infrared radiation layer. The infrared radiation layer receives the heat and radiates infrared light. The infrared light passes through the heating element 20 and enters the atomization chamber 21. At this time, the infrared light can heat the aerosol generation matrix to generate aerosol through the energy it carries. The heat provided by the heating wire 30 to the infrared radiation layer includes the heat directly transferred from the heating wire 30 to the infrared radiation layer and the heat generated by the heating wire 30 indirectly transferred to the infrared radiation layer through other structures (such as air).

[0070] In the accommodating cavity 51, the reflector 10 is sandwiched between the heating element 20 and the support 50, and the reflector 10 is at least partially opposite to the heating wire 30 and the infrared radiation layer. At this time, when the infrared light radiated by the infrared radiation layer propagates towards the outside of the atomizing cavity 21 in the direction perpendicular to its length, the infrared light is reflected on the surface of the reflector 10 near the heating element. At least a portion of the infrared light reflected by the reflector 10 is transmitted into the atomizing cavity 21 to heat the aerosol generation matrix. Therefore, the heating element 100 of this application uses the reflector 10 to block the heat generated by the heating wire 30 from the direction away from the atomizing cavity 21 and reflects the infrared light radiated by the infrared radiation layer into the atomizing cavity 21. This reduces the energy loss of the heating element 100, improves energy utilization, and allows for the generation of more aerosols with a better taste.

[0071] The sleeve 70 is a structure used to protect the conductive element 60. The sleeve 70 is fitted onto at least a portion of the outer peripheral wall of the conductive element 60. In this case, the conductive element 60 and the sleeve 70 together pass through the reflector 10 and the bracket 50, and are tightly fitted with the through-hole in the bracket 50 for the sleeve 70 to pass through. Exemplarily, the material of the sleeve 70 can be, but is not limited to, polyimide (PI), polytetrafluoroethylene (PTFE), and silicone rubber. Compared to the connection method where the conductive element 60 directly contacts the bracket 50, the friction between the outer surface of the sleeve 70 and the bracket 50 is greater. This optimizes the fixing method of the conductive element 60 and the heating wire 30 connected to the conductive element 60, increases the natural frequency of the heating wire 30, and makes it less prone to resonance.

[0072] Therefore, in the heating assembly 100 of this application, the heating element 20, heating wire 30, and reflector 10 are stably mounted on the bracket 50. The heating wire 30 is energized through the conductive element 60 and generates heat. The heat generated by the heating wire 30 is transferred to the infrared radiation layer, causing the infrared radiation layer to radiate infrared light and heat the aerosol generating matrix located in the atomization chamber 21 to generate aerosol. The aerosol generation process can proceed normally. The sleeve 70 is fitted outside the conductive element 60 and fits tightly with the bracket 50. Due to the large damping between the sleeve 70 and the bracket 50, the fixing method of the heating wire 30 is optimized, the natural frequency of the heating wire 30 is increased, and resonance is less likely to occur. The aerosol generating device 1000 will not generate noise during use, and the user has a better experience with the aerosol generating device 1000.

[0073] Please refer to Figures 1 to 3 In some embodiments, the heating assembly 100 further includes a sealing assembly 80, which is sandwiched between the bracket 50 and the heating element 20 and is configured to seal the gap between the heating element 20 and the bracket 50.

[0074] Specifically, the sealing component 80 is a structure used to seal the gap between the heating element 20 and the support 50. The sealing component 80 is disposed at the end of the heating element 20 and sandwiched between the heating element 20 and the support 50. The sealing component 80 and the heating element 20 can be detachably or non-detachably connected. Similarly, the sealing component 80 and the support 50 can also be detachably or non-detachably connected. Exemplarily, the sealing component 80 includes a ceramic fiber sheet. Because ceramics have advantages such as the ability to deform, high structural strength, and good high-temperature resistance, when a ceramic fiber sheet is used as at least a part of the structure of the sealing component 80, the sealing component 80 has good structural strength and is easy to deform, thus the sealing component 80 can effectively seal the gap between the heating element 20 and the support 50.

[0075] Therefore, in the heating assembly 100 of this application, the sealing assembly 80 seals the gap between the heating element 20 and the bracket 50 to prevent aerosol from leaking to the outside of the atomizing chamber 21, and to prevent the leaked aerosol from affecting the normal operation of other components, such as the heating wire 30, the reflector 10 and the circuit board (not shown), thereby improving the service life of the aerosol generating device 1000 and ensuring the health and safety of the inhaler.

[0076] Please refer to Figure 1 and Figure 8 Secondly, this application provides an aerosol generating apparatus 1000. The aerosol generating apparatus 1000 includes a battery assembly 300 and a heating assembly 100 as described in any of the above embodiments, wherein the heating wire 30 is electrically connected to the battery assembly 300.

[0077] Specifically, in the above practical method, it should be noted that the specific structure and properties of the heating component 100 in this embodiment are exactly the same as those in the above embodiments, and will not be repeated here. The aerosol generating device 1000 is a structure capable of generating aerosols by heating an aerosol generating matrix. The battery assembly 300 is used to provide electrical energy to the electrically powered components (e.g., the heating component 100) in the aerosol generating device 1000, enabling the heating component 100 to heat the atomized aerosol generating matrix to form aerosols.

[0078] For example, when the aerosol generating device 1000 is aspirated, the battery assembly 300 supplies power to the heating assembly 100, specifically by the battery assembly 300 transmitting power through the conductive element 60 to the heating wire 30. In this case, the heating wire 30 generates heat and excites the infrared radiation layer to radiate infrared light, thereby heating the aerosol generating matrix and generating aerosols. When the user does not aspirate the aerosol generating device 100, the battery assembly 300 stops supplying power to the heating assembly 100, and in this case, the heating assembly 100 does not heat the aerosol generating matrix. It should be noted that in some embodiments, the battery assembly 300 can be a dry cell battery or a rechargeable battery, etc. Rechargeable batteries include, but are not limited to, lithium-ion batteries, nickel-metal hydride batteries, and nickel-cadmium batteries.

[0079] In the aerosol generating apparatus 1000 of this application, both the heating element 20 and the heating wire 30 are housed in an annular reflector 10, with the heating wire 30 surrounding the side wall of the heating element 20. When the heating wire 30 is energized and generates heat, the heat directly or indirectly heats the aerosol generating matrix and generates aerosols. The reflector 10 reflects the heat generated by the heating wire 30 to improve energy utilization. The connector 40 is connected to both the heating wire 30 and the inner wall of the reflector 10 to support the heating wire 30. Because the connector 40 establishes a connection between the heating wire 30 and the reflector 10, the natural frequency of the heating wire 30 increases and differs significantly from the electrical excitation frequency received by the heating wire 30. Therefore, the heating wire 30 is less prone to resonance, and the aerosol generating apparatus 1000 does not generate noise during operation.

[0080] 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.

[0081] 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.
