[0027] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0029] In related technologies, aerosol generation devices include circumferential oxygen-free heating methods, where a rod-shaped aerosol matrix is ​​inserted into the receiving cavity of the heating component, and the periphery of the aerosol matrix is ​​directly heated through the cavity wall. Some aerosol matrices have a paper covering on their outer periphery; therefore, the aerosol generated by directly heating the periphery of the aerosol matrix may sometimes contain a paper smell or other odors, causing discomfort to customers and reducing customer satisfaction.

[0030] This application involves placing a coil on the bottom wall of the heating element away from the side wall. The coil is spirally wound in a planar shape to heat the bottom wall through electromagnetic induction. The heated bottom wall can directly heat the bottom side of the aerosol matrix, which helps to avoid the appearance of paper taste or other odors in the generated aerosol. Furthermore, the heat from the heated bottom wall can be conducted to the side wall, causing the side wall to heat the periphery of the aerosol matrix. Since the side wall heats indirectly through heat conduction, it also helps to avoid the appearance of paper taste or other odors in the generated aerosol, improves the taste of the generated aerosol, and helps to increase customer satisfaction.

[0031] The following describes some embodiments of the heating assembly provided in this application with reference to the accompanying drawings.

[0032] Please see Figures 1 to 3 This application provides a heating assembly, including a heating element 1, a coil 4, a base 3, and other functional components as needed, which are described in detail below.

[0033] In this embodiment, the heating element 1 includes a side wall 101 and a bottom wall 102, which together form a cavity 103 for inserting an aerosol matrix; a coil 4 is located on the side of the bottom wall 102 away from the cavity 103, and the coil 4 is spirally wound in a planar shape and is used to heat the bottom wall 102 through electromagnetic induction; the coil 4 is fixed on the base 3.

[0034] It is understood that the heating element 1 in this embodiment includes a side wall 101 and a bottom wall 102. The side wall 101 and the bottom wall 102 can be an integral structure. An integral structure heating element 1 is simpler to manufacture. In some embodiments, the side wall 101 and the bottom wall 102 of the heating element 1 can also be fixed together by connection. For example... Figure 6As shown, the cavity 103 formed by the side wall 101 and the bottom wall 102 has a structure with one end open and the other end closed, thereby enabling oxygen-free heating of the aerosol matrix 9 inserted in the cavity 103. In this embodiment, the aerosol matrix 9 can be rod-shaped, such as, but not limited to, a cigarette. The aerosol matrix 9 can be inserted into the cavity 103 only when in use; when not in use, it can be left uninserted. In this embodiment, the coil 4 is located on the side of the bottom wall 102 away from the cavity 103, and a gap can be left between the coil 4 and the bottom wall 102. The coil 4 is spirally wound in a planar shape, i.e., the coil 4 extends spirally from the center outwards; for example, it can be, but not limited to, a mosquito coil-shaped coil 4. In this embodiment, the coil 4 is fixed to the base 3, which facilitates the assembly of the coil 4. In this embodiment, the coil 4 can be connected to the power supply component 8 of the aerosol generating device. The power supply component 8 can provide AC power to the coil 4. When AC power is applied to the coil 4, an alternating magnetic field is generated. The bottom wall 102 of the heating element 1 is in this magnetic field and cuts the alternating magnetic field lines. An alternating current (i.e., eddy current) is generated in the bottom wall 102. The eddy current causes the charge carriers in the bottom wall 102 to move at high speed and randomly. The charge carriers collide and rub against each other to generate heat energy, thereby heating the bottom wall 102 of the heating element 1. In this embodiment, the material of the heating element 1 can be a material that can be heated by electromagnetic induction. In this embodiment, the base 3 can be made of a material that cannot or is almost impossible to be heated by electromagnetic induction.

[0035] The heating assembly provided in this embodiment includes a heating element 1 and a coil 4. The coil 4 is spirally wound in a planar shape to heat the bottom wall 102 through electromagnetic induction. After the coil 4 is energized, the bottom wall 102 of the heating element 1 can be heated through electromagnetic induction. The heated bottom wall 102 can directly heat the bottom side of the aerosol matrix 9, which helps to avoid the appearance of paper taste or impurities in the generated aerosol. The heat from the heated bottom wall 102 can be conducted to the side wall 101, which heats the side wall 101 and heats the periphery of the aerosol matrix 9. Since the side wall 101 heats indirectly through heat conduction, it also helps to avoid the appearance of paper taste or impurities in the generated aerosol when directly heated in the circumferential direction, improves the taste of the generated aerosol, and helps to improve customer satisfaction.

[0036] In one embodiment, such as Figure 2 As shown, the thickness of the bottom wall 102 can be greater than the thickness of the side wall 101, which facilitates the conduction of heat from the bottom wall 102 to the side wall 101. The thicker the bottom wall 102, the more heat it can transfer to the side wall 101, and the better the effect of heat transfer from the bottom wall 102 to the side wall 101, causing the side wall 101 to heat up. In some embodiments, when the side wall 101 has sufficiently good thermal conductivity, the thickness of the bottom wall 102 can also be equal to the thickness of the side wall 101.

[0037] In one embodiment, such as Figure 2 , Figure 3 As shown, the base 3 has a mounting cavity 303. One end of the heating element 1 with a bottom wall 102 is inserted into the mounting cavity 303 and connected to the base 3. The coil 4 is fixed to the bottom surface of the mounting cavity 303. The base 3 can not only mount the coil 4, but also fix the bottom end of the heating element 1, which helps to reduce the number of parts in the device. In some embodiments, the bottom of the heating element 1 may not be connected to the base 3 as needed. The base 3 may only be used to mount the coil 4, and the bottom end of the heating element 1 may be connected to other components in the aerosol generating device. For example, the bottom end of the heating element 1 may be directly connected and fixed to the bracket 7 in the aerosol generating device. In this embodiment, the coil 4 is fixed to the bottom surface of the mounting cavity 303. In order to facilitate the electrical connection between the coil 4 and the power supply component 8, the base 3 may also be provided with holes for wires to pass through.

[0038] In one embodiment, the bottom surface of the mounting cavity 303 is provided with a spiral groove, and the coil 4 is fixed in the groove to form a planar spirally wound coil 4. Fixing the coil 4 through the groove not only facilitates the assembly of the coil 4, but also defines the spiral shape of the coil 4, which helps to improve the stability of the magnetic field generated after the coil 4 is energized. In some embodiments, the groove can also be fixed to the base 3 in other ways. For example, the coil 4 can be wound into a planar spiral shape and fixed with cable ties or fixing plates, and then fixed to the base 3 by adhesive or snap-fit.

[0039] In one embodiment, such as Figure 2 , Figure 3 As shown, a magnetic ring 5 is fixed on the base 3, and a coil 4 is disposed on the outer periphery of the magnetic ring 5. A gap is left between the coil 4, the magnetic ring 5, and the bottom wall 102. The magnetic ring 5 can absorb and attenuate the magnetic field generated by the high-frequency current, suppressing electromagnetic interference generated when the coil 4 is working, which is beneficial to improving the heating efficiency of the heating component. The magnetic ring 5 can be made of magnetic materials, such as ferrite magnetic materials. Magnetic materials have high permeability and low resistivity, which is beneficial for absorbing and attenuating the magnetic field generated by the high-frequency current. In this embodiment, a gap is left between the coil 4 and the bottom wall 102, and between the magnetic ring 5 and the bottom wall 102, which helps to avoid direct contact that may affect the coil 4 and the magnetic ring 5 when the temperature of the bottom wall 102 is too high. In some embodiments, the magnetic ring 5 can be fixed to the middle of the bottom surface of the mounting cavity 303 by adhesive bonding, and the coil 4 can gradually extend spirally towards the outer edge of the bottom surface of the mounting cavity 303, starting from the area around the outer periphery of the magnetic ring 5.

[0040] In one embodiment, such as Figure 3 , Figure 6As shown, the accommodating cavity 103 is an elliptical hole, and the opposite two sides of the elliptical hole corresponding to the minor axis of the ellipse are used to compress the aerosol matrix 9. When the aerosol matrix 9 is inserted into the accommodating cavity 103, the opposite two sides of the elliptical hole corresponding to the minor axis of the ellipse will compress the aerosol matrix 9, causing the aerosol matrix 9 to deform and making good contact between the aerosol matrix 9 and the cavity wall of the accommodating cavity 103. This is beneficial to improving the heat conduction efficiency between the aerosol matrix 9 and the heating component and shortening the preheating time of the aerosol matrix 9. In this embodiment, the aerosol matrix 9 can be cylindrical. After being compressed by the elliptical hole, the aerosol matrix 9 can also take on an approximately elliptical shape. After deformation, the distance from the cavity wall of the accommodating cavity 103 to the center of the aerosol matrix 9 can be reduced, which is beneficial to shortening the preheating time of the aerosol matrix 9. In some embodiments, the accommodating cavity 103 can also be a circular hole or a rectangular hole.

[0041] In one embodiment, such as Figure 1 , Figure 2 As shown, the heating assembly also includes a support frame 2. The heating element 1 is disposed within the support frame 2. The end of the heating element 1 away from the bottom wall 102 is connected and fixed to the support frame 2. The support frame 2 has an insertion port 201 communicating with the accommodating cavity 103. The end of the support frame 2 away from the insertion port 201 is connected and fixed to the base 3. The support frame 2 facilitates the assembly of the heating element 1 in the aerosol generating device. The heating element 1 is installed inside the support frame 2. The support frame 2 can be made of a material with good heat insulation properties. By isolating the heat generated by the heating element 1 through the support frame 2, it helps to avoid discomfort to the user due to overheating of the shell 6. In some embodiments, the support frame 2 may not be connected to the base 3. For example, the support frame 2 may be directly connected and fixed to the bracket 7 of the aerosol generating device. In some application scenarios, when the shell 6 has good heat insulation properties, the heating assembly may not have a support frame 2, and the end of the heating element 1 away from the bottom wall 102 may be directly connected to the shell 6.

[0042] The heating assembly provided in the above embodiment includes a heating element 1 and a coil 4. The coil 4 is spirally wound in a planar shape to heat the bottom wall 102 through electromagnetic induction. The coil 4 is fixed on the base 3, and a magnetic ring 5 is fixed on the base 3. After the coil 4 is energized, the bottom wall 102 of the heating element 1 can be heated through electromagnetic induction. The heated bottom wall 102 can directly heat the bottom side of the aerosol matrix 9, which helps to avoid the appearance of paper smell or impurities in the generated aerosol. The heat from the heated bottom wall 102 can be conducted to the side wall 101, which heats the side wall 101 and heats the periphery of the aerosol matrix 9. Since the side wall 101 heats indirectly through heat conduction, it also helps to avoid the appearance of paper smell or impurities in the generated aerosol, improves the taste of the generated aerosol, and helps to improve customer satisfaction. Furthermore, the magnetic ring 5 can absorb and attenuate the magnetic field generated by the high-frequency current, suppress the electromagnetic interference generated when the coil 4 is working, and help to improve the heating efficiency of the heating assembly.

[0043] Please see Figures 1 to 6 This application also provides an aerosol generating device, including a housing 6, a power supply component 8, and a heating component as described above. The heating component and the power supply component 8 are disposed inside the housing 6, and the coil 4 is electrically connected to the power supply component 8.

[0044] It is understood that the power supply component 8 in this embodiment may include, but is not limited to, a battery and a circuit board. The electrical connection between the power supply component 8 and the coil 4 may be an electrical connection between the circuit board of the power supply component 8 and the coil 4. The housing 6 in this embodiment may have a hole structure corresponding to the insertion port of the accommodating cavity 103, so as to allow the aerosol matrix 9 to be inserted into the accommodating cavity 103. A bracket 7 may be provided inside the housing 6 in this embodiment, and the heating component may be fixedly connected to the housing 6 and the bracket 7 through its included support frame 2.

[0045] In one embodiment, such as Figure 2 , Figure 5 As shown, the aerosol generating device also includes a support 7 housed within the housing 6. Two L-shaped connecting portions 301 are provided on the side of the base 3 away from the heating element 1, symmetrically arranged. Two L-shaped limiting portions 701 are symmetrically provided on the support 7. The two connecting portions 301 hook onto their corresponding limiting portions 701, connecting the base 3 to the support 7. The two L-shaped connecting portions 301 hook onto their corresponding L-shaped limiting portions 701, simplifying assembly and preventing rotation of the base 3 after assembly. In some embodiments, the base 3 can also be connected and fixed to the support 7 via other connection methods, such as screw connection, adhesive bonding, etc. In some applications, the heating component can also be connected to the support 7 via other components, for example, the bottom of the support frame 2 can be connected and fixed to the support 7.

[0046] In one embodiment, an elastic locking arm 302 is provided between the two connecting parts 301, and the bracket 7 has a protrusion 702 located between the two limiting parts. The elastic locking arm 302 is correspondingly locked with the protrusion 702. After locking, the connecting part 301 can be prevented from dislodging from the limiting part 701, thereby improving the stability of the connection between the base 3 and the bracket 7. The elastic locking arm 302 is cantilevered and has a certain elastic deformation capability. When the connecting part 301 is inserted into the limiting part 701 from one side, the elastic locking arm 302 is squeezed and deformed by the protrusion 702. After the connecting part 301 completely hooks the limiting part 701, the elastic locking arm 302 slides past the protrusion 702 and is no longer squeezed by the protrusion 702. At this time, the elastic locking arm 302 can recover its deformation so that the free end of the elastic locking arm 302 abuts against the protrusion 702 to form a limiting. In some embodiments, other structures may be used to prevent the connecting part 301 from dislodging from the limiting part 701.

[0047] The heating component in the aerosol generating device provided in this application can be the same as that in the above embodiments. For ease of understanding, some specific embodiments of the heating component in the aerosol generating device are provided below.

[0048] In one embodiment, such as Figure 2 As shown, the thickness of the bottom wall 102 of the heating element 1 of the heating component is greater than the thickness of the side wall 101, which is conducive to the conduction of heat from the bottom wall 102 to the side wall 101. The thicker the bottom wall 102, the more heat it can transfer to the side wall 101, and the better the effect of the heat from the bottom wall 102 to the side wall 101 causing the side wall 101 to heat up.

[0049] In one embodiment, such as Figure 2 , Figure 3 As shown, the base 3 of the heating assembly has a mounting cavity 303. One end of the heating element 1 with a bottom wall 102 is inserted into the mounting cavity 303 and connected to the base 3. The coil 4 is fixed to the bottom surface of the mounting cavity 303. The base 3 can not only mount the coil 4, but also fix the bottom end of the heating element 1, which helps to reduce the number of parts in the device. In this embodiment, the coil 4 is fixed to the bottom surface of the mounting cavity 303. In order to facilitate the electrical connection between the coil 4 and the power supply assembly 8, the base 3 can also be provided with holes for wires to pass through.

[0050] In one embodiment, the bottom surface of the mounting cavity 303 of the base 3 is provided with a spiral groove, and the coil 4 is fixed in the groove to form a planar spirally wound coil 4. Fixing the coil 4 through the groove not only facilitates the assembly of the coil 4, but also defines the spiral shape of the coil 4, which helps to improve the stability of the magnetic field generated after the coil 4 is energized.

[0051] In one embodiment, such as Figure 2 , Figure 3 As shown, a magnetic ring 5 is fixed on the base 3 of the heating assembly, and a coil 4 is disposed on the outer periphery of the magnetic ring 5. A gap is left between the coil 4, the magnetic ring 5, and the bottom wall 102. The magnetic ring 5 can absorb and attenuate the magnetic field generated by the high-frequency current, suppressing electromagnetic interference generated when the coil 4 is working, which is beneficial to improving the heating efficiency of the heating assembly. The magnetic ring 5 can be made of magnetic materials, such as ferrite magnetic materials. Magnetic materials have high permeability and low resistivity, which is beneficial for absorbing and attenuating the magnetic field generated by the high-frequency current. In this embodiment, a gap is left between the coil 4 and the bottom wall 102, and between the magnetic ring 5 and the bottom wall 102, which helps to avoid direct contact that may affect the coil 4 and the magnetic ring 5 when the temperature of the bottom wall 102 is too high. In some embodiments, the magnetic ring 5 can be fixed to the middle of the bottom surface of the mounting cavity 303 by adhesive bonding, and the coil 4 can gradually extend spirally towards the outer edge of the bottom surface of the mounting cavity 303, starting from the area around the outer periphery of the magnetic ring 5.

[0052] In one embodiment, such as Figure 3 , Figure 6 As shown, the housing 103 of the heating element 1 of the heating component is an elliptical hole. The opposite side walls of the elliptical hole, corresponding to the minor axis of the ellipse, are used to compress the aerosol matrix 9. When the aerosol matrix 9 is inserted into the housing 103, the opposite side walls of the elliptical hole, corresponding to the minor axis of the ellipse, compress the aerosol matrix 9, causing it to deform. This ensures good contact between the aerosol matrix 9 and the cavity wall of the housing 103, which is beneficial for improving the heat conduction efficiency between the aerosol matrix 9 and the heating component, and shortening the preheating time of the aerosol matrix 9. In this embodiment, the aerosol matrix 9 can be cylindrical. After being compressed by the elliptical hole, the aerosol matrix 9 can also take on an approximately elliptical shape. After deformation, the distance from the cavity wall of the housing 103 to the center of the aerosol matrix 9 can be reduced, which is beneficial for shortening the preheating time of the aerosol matrix 9.

[0053] The aerosol generating device provided in the above embodiment includes a heating element 1 and a coil 4. The coil 4 is spirally wound in a planar shape to heat the bottom wall 102 through electromagnetic induction. After the coil 4 is energized, the bottom wall 102 of the heating element 1 can be heated through electromagnetic induction. The heated bottom wall 102 can directly heat the bottom side of the aerosol matrix 9, which helps to avoid the appearance of paper taste or impurities in the generated aerosol. The heat from the heated bottom wall 102 can be conducted to the side wall 101, which heats the side wall 101 and heats the periphery of the aerosol matrix 9. Since the side wall 101 heats indirectly through heat conduction, it also helps to avoid the appearance of paper taste or impurities in the generated aerosol, improves the taste of the generated aerosol, and helps to improve customer satisfaction.

[0054] 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.
