Description

Technical Field

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

[0002] In the field of aerosol generating devices (such as heat-not-burning devices, or HNB devices), the heating element is the core component for aerosol generation, and its performance directly affects the efficiency of aerosol generation, the user experience, and the lifespan of the device. Currently, thick-film heating elements are widely used as the core heating element in aerosol generating devices. These elements are formed by printing resistive paste onto a ceramic substrate and sintering it to create heating circuits, which are then combined with electrodes and leads to convert electrical energy into heat energy.

[0003] However, the bonding strength between the resistive paste of the thick film heating element and the ceramic substrate is limited. Under the thermal stress of repeated heating and cooling cycles, the resistive paste is prone to local peeling, which may lead to open circuits. Furthermore, the thick film material has weak resistance to mechanical impact. When the aerosol generating device is subjected to slight vibration or stress, the heating film layer may crack, further aggravating the failure of the heating circuit. Utility Model Content

[0004] This application provides a heating element and an aerosol generating device, which can solve the problem that the heating circuit of the heating element is prone to failure during use.

[0005] To address the aforementioned technical problems, this application provides a heating element applied to an aerosol generating device. The heating element includes at least two conductive heating elements and at least one cantilever. The conductive heating elements are configured to bend and elastically deform under external force. The at least two conductive heating elements are arranged sequentially and spaced apart along the circumference so that each conductive heating element forms a different heating zone. A receiving cavity is formed within the at least two conductive heating elements to accommodate the aerosol matrix, and one end of the receiving cavity has an insertion port. The cantilever is located on the side of the conductive heating element away from the insertion port to support the aerosol matrix, and at least one cantilever is used to connect the conductive heating elements in pairs.

[0006] In one embodiment, the cantilever is disposed within the accommodating cavity, and the two ends of the cantilever are respectively connected to the inner walls of different conductive heating elements.

[0007] In one embodiment, there are two conductive heating elements, namely a first heating element and a second heating element. The first heating element has a first end and a second end in the circumferential direction, and the second heating element has a third end and a fourth end in the circumferential direction. The first end is disposed close to the third end, and the second end is disposed close to the fourth end. The two ends of the cantilever are respectively connected to the first end and the fourth end, or the two ends of the cantilever are respectively connected to the second end and the third end.

[0008] In one embodiment, the cantilever is configured as a conductive cantilever for connecting a common lead, and each conductive heating element is used to connect to a different conductive lead, so that each heating zone can heat up independently.

[0009] In one embodiment, the conductive heating element is in the shape of an arc plate, and / or the cantilever is configured to bend elastically under external force, the cantilever including an arc plate-shaped structure.

[0010] In one embodiment, the heating element further includes an outer tube having an assembly cavity, and a conductive heating element is disposed in the assembly cavity; the conductive heating element is bent and elastically deformed under the limitation of the cavity wall of the assembly cavity to generate an elastic force toward the inner wall of the assembly cavity, so that the conductive heating element can be tightly attached to the inner wall of the assembly cavity.

[0011] In one embodiment, the cantilever has a positioning post or positioning hole for assembling and positioning the heating element; and / or, the cantilever has an air inlet.

[0012] In one embodiment, the cantilever is integrally formed with each conductive heating element, or the elastic modulus of the cantilever is less than the elastic modulus of the conductive heating element.

[0013] In one embodiment, at least one conductive heating element has a hollow structure or a groove structure.

[0014] To address the aforementioned technical problems, this application provides an aerosol generating device, including a housing assembly and a heating element as described above, wherein the heating element is assembled within the housing assembly.

[0015] This application provides a heating element and an aerosol generating device. The heating element uses a conductive heating sheet instead of a traditional thick-film heating element. The conductive heating sheet is an integrated structure, unlike the combined "resistive paste and ceramic substrate" structure of thick-film heating elements, thus avoiding the peeling problem caused by insufficient bonding strength between different materials. Furthermore, the conductive heating sheet itself has higher structural strength than the fragile film layer, naturally possessing stronger resistance to mechanical impact and deformation, and is less prone to cracking due to vibration or stress. The various conductive heating sheets are cantilevered to form an integral structure, creating a cavity within the conductive heating sheet to accommodate the aerosol matrix. The conductive heating sheet can be directly assembled with the aerosol matrix, whereas traditional film layers, without bonding to a ceramic substrate, cannot be directly molded into a structure with a cavity. Moreover, each conductive heating sheet can undergo bending elastic deformation under external force. This characteristic allows the heating element to form a tight fit with other components of the aerosol generating device when assembled into the housing assembly, relying on its own elasticity. Stable assembly can be completed without relying on additional fixing structures or connecting parts, reducing assembly steps and improving production efficiency. Attached Figure Description

[0027] Please refer to Figure 1-4 This application provides a heating element 10, which is applied to an aerosol generating device, such as... Figure 4 As shown, the heating element 10 is used to contain and heat the aerosol matrix 20.

[0028] The aerosol matrix 20 includes at least a matrix segment, which is used to generate aerosols upon heating. Therefore, after the aerosol matrix 20 is inserted into the heating element 10, at least the matrix segment is located within the heating element 10 to facilitate heating of the matrix segment. In one embodiment, the aerosol matrix 20 further includes a coating layer that surrounds the matrix segment. The matrix segment is primarily composed of tobacco, herbal or plant leaves, or medicinal materials. It is understood that the materials forming the matrix segment are not limited; the matrix segment can be formed from a single material or from a mixture of multiple materials in different proportions.

[0029] The coating layer can be formed of a coating material such as paper, thereby maintaining the shape of the matrix segment. The material forming the coating layer is not limited to this; in other embodiments, the coating layer can also be formed of other materials such as aluminum foil to meet different requirements. In one embodiment, the aerosol matrix 20 further includes a nozzle segment, a cooling segment, and a sealing segment, which are arranged sequentially along the axis of the matrix segment. The nozzle segment mainly has a filtering function, through which the user inhales the aerosol. The nozzle segment may contain a filter medium that can filter tar, suspended particles, etc., in the aerosol, thereby reducing unwanted substances in the aerosol inhaled by the user. The filter medium can be, for example, a polylactic acid filament tow or a cellulose acetate filament tow. The main function of the cooling segment is to reduce the temperature of the aerosol to prevent burns to the mouth. The cooling segment has a cooling channel, and the inner wall of the cooling channel has cooling holes communicating with the outside of the cooling segment. After being generated in the matrix section, the aerosol flows through the cooling channel and finally exits from the nozzle section for the user to inhale. As the aerosol passes through the cooling channel, cold air can enter the cooling channel through the cooling holes under negative pressure to mix with the aerosol and lower its temperature.

[0030] The cooling section can be made of one of the following materials: polylactic acid / aluminum foil composite film, paper filter rod, polylactic acid nonwoven fabric, polylactic acid granules, polylactic acid filament braided tube, serrated polylactic acid folded film, cellulose acetate, or cooling activated carbon composite material. The sealing section is located at the end of the aerosol matrix 20 and provides a physical support base to prevent the particles or materials of the aerosol matrix 20 from loosening or falling off during heating, maintaining the integrity of the aerosol matrix 20. This avoids leakage due to thermal expansion or movement of the matrix section, which would affect the user experience. The sealing section generally allows gas to pass through, facilitating airflow from the bottom of the aerosol matrix 20 into the matrix section. Furthermore, if condensate is generated in the cooling section or matrix section, the fiber structure of the sealing section can prevent the liquid from flowing out of the aerosol matrix 20. Additionally, the sealing section can control airflow resistance through fiber density to ensure smooth suction. Materials for the sealing section include, for example, polypropylene fiber, polyester fiber, cotton, and cellulose acetate. In other embodiments, the aerosol matrix 20 may not have at least one of the cooling section, sealing section, and nozzle section, or the aerosol matrix 20 may have other functional sections, which will not be described in detail here.

[0031] like Figure 1-4 As shown, the heating element 10 includes at least two conductive heating elements 11 and at least one cantilever 12. For example, in Figure 1-4 In one embodiment, the heating element 10 includes two conductive heating elements 11 and a cantilever 12. In other embodiments, the heating element 10 may include more than two conductive heating elements 11 and more than one cantilever 12.

[0032] The conductive heating element 11 is configured to bend and elastically deform under external force, allowing for component assembly based on its own elasticity. The conductive heating element 11 can be made of metal or alloy; for example, it can be made of β-titanium alloy, titanium-6aluminum-4vanadium alloy, pure titanium, nickel-based high-temperature alloy, stainless steel, permalloy, etc. The material selection for the conductive heating element 11 needs to consider high-temperature stability, high-temperature resistance, elasticity, and conductivity. The hardness is primarily medium to high, with a moderate elastic modulus ranging from 80GPa to 200GPa. This ensures structural rigidity, prevents excessive deformation, and provides sufficient elasticity to meet the requirements of assembly based on its own elasticity. Furthermore, the conductive heating element 11 is configured as a sheet-like material, with a thickness much smaller than its length and width, facilitating bending deformation.

[0033] At least two conductive heating elements 11 are arranged sequentially and spaced apart along the circumference, so that each conductive heating element 11 forms a different heating zone. By arranging the conductive heating elements 11 spaced apart, the independence of the different heating zones can be improved. By arranging the conductive heating elements 11 sequentially along the circumference, the conductive heating elements 11 can enclose each other, forming an accommodating cavity 13 within at least two conductive heating elements 11. Figure 4 As shown, the accommodating cavity 13 is used to accommodate the aerosol matrix 20. One end of the accommodating cavity 13 has a socket 131 through which the aerosol matrix 20 can be inserted into the accommodating cavity 13. By directly installing the aerosol matrix 20 inside the conductive heating element 11, the conductive heating element 11 can generate resistance heating when current flows through it, thereby circumferentially heating the aerosol matrix 20, which greatly improves the heating efficiency of the conductive heating element 11 for the aerosol matrix 20.

[0034] like Figure 1-4 As shown, the cantilever 12 is located on the side of the conductive heating element 11 away from the socket 131, and is used to support the aerosol matrix 20, that is, the bottom surface of the aerosol matrix 20 can abut the top surface of the cantilever 12. The axial height of the cantilever 12 in the accommodating cavity 13 is less than the axial height of the conductive heating element 11. At least one cantilever 12 is used to connect each conductive heating element 11 in pairs, that is, each cantilever 12 connects two different conductive heating elements 11 at both ends. The number of cantilever 12 needs to be sufficient to connect all the conductive heating elements 11 into a whole when each cantilever 12 connects two different conductive heating elements 11, so that the conductive heating elements 11 can maintain the shape of enclosing the accommodating cavity 13.

[0035] The heating element 10 provided in this application uses a conductive heating element 11 instead of a traditional thick-film heating element. The conductive heating element 11 is an integrated structure, unlike the combined "resistive paste and ceramic substrate" structure of a thick-film heating element. This avoids the peeling problem caused by insufficient bonding strength between different materials. Furthermore, the conductive heating element 11 itself has higher structural strength than the fragile film layer, naturally possessing stronger resistance to mechanical impact and deformation, and is less prone to cracking due to vibration or stress. The various conductive heating elements 11 are connected by cantilever 12 to form an integral structure, creating a cavity 13 within the conductive heating element 11 to accommodate the aerosol matrix 20. The conductive heating element 11 can be directly assembled with the aerosol matrix 20, whereas traditional film layers, without bonding to a ceramic substrate, cannot be directly molded into a structure with a cavity 13. Furthermore, each conductive heating element 11 can undergo bending elastic deformation under external force. This characteristic allows the heating element 10 to form a tight fit with other components of the aerosol generating device when assembled on the housing assembly 30, relying on its own elasticity. Stable assembly can be completed without relying on additional fixing structures or connecting parts, reducing assembly steps and improving production efficiency.

[0036] like Figure 5 As shown, in one embodiment, the heating element 10 further includes an outer tube 14, which has an assembly cavity, and a conductive heating element 11 is disposed within the assembly cavity. The conductive heating element 11 undergoes elastic deformation under the constraint of the cavity wall, generating an elastic force towards the inner wall of the assembly cavity, so that the conductive heating element 11 can fit tightly against the inner wall of the assembly cavity. The outer tube 14 defines the boundary of the conductive heating element 11, allowing each conductive heating element 11 to be formed into a tubular shape suitable for accommodating the aerosol matrix 20, ensuring that the conductive heating element 11 maintains a stable structure during operation and preventing positional displacement from affecting the heating effect. The outer tube 14 can be configured as, for example, a glass tube, a ceramic tube, etc. The outer tube 14 can be made of a material with high temperature resistance and good thermal insulation properties to reduce excessive heat conduction from the conductive heating element 11 to the outside, reduce the risk of damage to other components of the aerosol generating device due to high temperature, reduce heat loss, and improve heating efficiency. Of course, in other embodiments, the heating element 10 may not include the outer tube 14, and the conductive heating element 11 may be directly assembled into the housing assembly 30 of the aerosol generating device.

[0037] In one embodiment, such as Figure 1-4As shown, cantilever 12 is disposed within the accommodating cavity 13, with each end of cantilever 12 connected to the inner wall of a different conductive heating element 11. By disposing of the cantilever 12 within the accommodating cavity 13, the cantilever 12 can support each conductive heating element 11 within the conductive heating element 11, thereby improving the overall structural rigidity of the heating element 10 and reducing the risk of localized inward collapse of the conductive heating element 11 during elastic deformation or high-temperature operation. Preferably, the cantilever 12 spans across the accommodating cavity 13, and the greater the span of the cantilever 12 within the accommodating cavity 13, the better; that is, the longer the length of the cantilever 12 in the radial cross-section, the better, as this is more conducive to preventing localized inward collapse.

[0038] In one embodiment, there are two conductive heating elements 11, namely a first heating element 111 and a second heating element 112. The first heating element 111 has a first end 1111 and a second end 1112 in the circumferential direction, and the second heating element 112 has a third end 1121 and a fourth end 1122 in the circumferential direction. The first end 1111 is disposed near the third end 1121, and the second end 1112 is disposed near the fourth end 1122. The two ends of the cantilever 12 are respectively connected to the first end 1111 and the fourth end 1122, while the second end 1112 and the third end 1121 are free ends; or, the two ends of the cantilever 12 are respectively connected to the second end 1112 and the third end 1121, while the first end 1111 and the fourth end 1122 are free ends. By connecting one end of the cantilever 12 and the conductive heating element 11, the end of the conductive heating element 11 that is not connected to the cantilever 12 can become a free end. When an external force is applied to the conductive heating element 11, the free end can undergo more flexible bending elastic deformation, and the magnitude of the deformation can be controlled by the support strength of the cantilever 12. This ensures that the conductive heating element 11 can fit the external assembly parts through elastic deformation, while avoiding excessive deformation that could lead to structural failure.

[0039] In other embodiments, the number of conductive heating elements 11 may be two or more, and the number of cantilever 12 may be one or more. The connection between the cantilever 12 and the conductive heating element 11 can refer to the above embodiments, so that the two ends of the same cantilever 12 are respectively connected to two different conductive heating elements 11, and each cantilever 12 is connected to one end of the conductive heating element 11 in the circumferential direction, so that one end of each conductive heating element 11 is connected to the cantilever 12, and the other end forms a free end. The cantilever 12 needs to have a certain span in the accommodating cavity 13 to ensure the support of the cantilever 12 inside the accommodating cavity 13.

[0040] In one embodiment, the cantilever 12 is configured as a conductive cantilever 12, used to connect a common lead. Each conductive heating element 11 is used to connect to different conductive leads, so that each heating area can heat up independently. The common lead and conductive leads can be connected to the positive and negative terminals of a power supply, respectively. Thus, when one or some conductive leads are energized and the others are de-energized, the heating area connected to the energized conductive lead, the cantilever 12, the conductive lead, and the common lead can form a circuit with the power supply, causing the heating area connected to the energized conductive lead to generate heat. Therefore, the heat generation of a certain heating area or certain heating areas can be controlled individually, preventing the overall heating temperature of the aerosol matrix 20 from being too high and causing the aerosol to burn the mouth. Of course, in other embodiments, the cantilever 12 can also be made of a non-conductive material. When it is necessary to control the heating of the heating area individually, a pair of conductive leads needs to be connected to each conductive heating element 11, and the pair of conductive leads on each conductive heating element 11 is used to connect to the positive and negative terminals of the power supply, respectively.

[0041] In one embodiment, the conductive heating element 11 is arc-shaped. By making the conductive heating element 11 arc-shaped, the arc shape is easier to adapt to the curvature of the inner wall of the outer tube 14, and the arc shape has a greater elastic deformation capability. The cantilever 12 is configured to bend and elastically deform under the action of external force, and the cantilever 12 includes an arc-shaped structure. By also making the cantilever 12 a bendable and elastically deformable cantilever 12, the elastic deformation capability of the heating element 10 can be further enhanced, ensuring that the heating element 10 can be positioned with its own elastic force.

[0042] like Figure 1 and Figure 2 As shown, in one embodiment, the cantilever 12 has a positioning post or positioning hole 121 for assembling and positioning the heating element 10. The positioning post can be interference-fitted with holes in other components, and the positioning hole 121 can be interference-fitted with protrusions in other components. The positioning hole 121 can also mate with threaded holes in other components, and the cantilever 12 and other components can be locked together using screws or other threaded components. By setting the positioning structure, the rigid positioning of the heating element 10 can be achieved through the tight engagement of the mechanical structure, avoiding slight offsets that may occur if positioning is solely based on elastic force. This makes the relative position of the heating element 10 and the aerosol matrix 20 more precise, ensuring uniform heating.

[0043] In one embodiment, the cantilever 12 has an air inlet. The air inlet allows external airflow to enter the accommodating cavity 13. When the air inlet is used as the main air intake channel, other open spaces on the side of the accommodating cavity 13 away from the insertion port 131 need to be blocked. By providing the air inlet, a stable airflow supply can be ensured during the heating process.

[0044] In one embodiment, the cantilever 12 and each conductive heating element 11 are integrally formed, meaning the cantilever 12 and the conductive heating element 11 are made of the same material. This integral design avoids weak points in the connection between the cantilever 12 and the conductive heating element 11, significantly enhancing the fatigue resistance of the overall structure. Simultaneously, integral forming reduces the number of parts and assembly steps, lowering production complexity. Alternatively, the cantilever 12 and the conductive heating element 11 may be made of different materials, and the elastic modulus of the cantilever 12 may be less than that of the conductive heating element 11. This means the elastic deformation capacity of the cantilever 12 is greater than that of the conductive heating element 11, allowing the cantilever 12 to bear the primary elastic deformation function, while the heating element maintains structural stability to ensure the shape of the heating area.

[0045] In one embodiment, at least one conductive heating element 11 is provided with a hollow structure or a groove structure, wherein the length direction of at least a portion of the hollow structure or groove structure is consistent with the circumferential direction of the accommodating cavity 13. This enhances the circumferential elastic deformation capability of the conductive heating element 11 without significantly weakening its overall rigidity. Furthermore, the hollow structure or groove structure can also serve as an effective means of adjusting the resistance of the conductive heating element 11.

[0046] like Figure 6 As shown, this application provides an aerosol generating device, including a housing assembly 30 and a heating element 10 as described above, wherein the heating element 10 is assembled within the housing assembly 30. Furthermore, the aerosol generating device may also include electronic components such as a power supply and a circuit board. The power supply can supply power to the heating element 10, and the circuit board can control the heating state of the heating element 10.

[0047] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
