For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
Referring to fig. 1 to 3, an embodiment of the present invention provides an electromagnetic heating device 1 for an aerosol-generating device (not shown), comprising a conductive coil 2, an induction heating element 3, the induction heating element 3 being provided with a housing cavity 31, the housing cavity 31 being for housing an aerosol-generating substrate (not shown), the induction heating element 3 extending in a first direction (X direction shown in fig. 1 to 2) perpendicular to an axial direction (Y direction shown in fig. 1 to 2) of the conductive coil 2.
In the present embodiment, the conductive coil 2 is supplied with power from an internal or external power source, and generates magnetic lines of force 21 to cut the induction heating element 3 when energized. The induction heating body 3 is provided with a housing chamber 31, and the housing chamber 31 is used for housing an aerosol-generating substrate, which may be tobacco, tobacco tar, tobacco paste, or the like, as required. The induction heating element 3 cut by the magnetic force lines 21 generates an induced electromotive force E to form an eddy current 22, and the temperature of the induction heating element 3 increases, thereby heating the aerosol-generating substrate in the accommodating chamber 31. The induction heating element 3 extends in a first direction (X direction shown in fig. 1-2), that is, a longitudinal direction of the induction heating element 3, which is perpendicular to an axial direction of the conductive coil 2 (Y direction shown in fig. 1-2), that is, an angle a=90° in fig. 1. The conductive coil 2 may have a variety of different shapes as desired. In one embodiment, referring to fig. 1, the conductive coil 2 is similar to the cylindrical shape of a cylinder spring. In another embodiment, referring to fig. 2, the conductive coil 2 may be flat, and the direction perpendicular to the plane of the conductive coil 2, that is, the axial direction (Y direction shown in fig. 2) of the conductive coil 2. In other embodiments, the conductive coil 2 may have other shapes, and the direction perpendicular to the axial direction of the conductive coil means that the magnetic force lines 21 generated by the conductive coil 2 after being energized only cut the side surface of the induction heating body 3. In the present embodiment, since the longitudinal direction of the induction heating element 3 is perpendicular to the axial direction of the conductive coil 2, the magnetic lines of force 21 generated after the conductive coil 2 is energized cut out the side surface of the induction heating element 3 rather than the cross section. For the electromagnetic heating device 1, the area of the object side forming the accommodation chamber 31 is much larger than the area of the cross section in order to better accommodate the aerosol-generating substrate. Referring to fig. 7, when the magnetic field strength B is constant, the larger the area Scos θ perpendicular to the magnetic field is, the larger the corresponding magnetic flux Φ is, and the larger the amount of change ΔΦ in the magnetic flux that can be achieved at the time of variable frequency power output is, the larger the eddy current 22 generated by the induced electromotive force E is, the faster the temperature rise of the induction heating element 3 is, and the higher the heating efficiency is. Preferably, the induction heating body 3 is made of nickel, iron, alloy steel, manganese and other materials with high magnetic permeability, so that the heating efficiency is further improved.
By adopting the above technical scheme, the electromagnetic heating device 1 disclosed in the embodiment has high heating efficiency when applied. In particular, the electromagnetic heating device 1 according to the present embodiment is used for heating an aerosol-generating device that does not burn, and the preheating time is also greatly shortened. The conductive coil 2 may be disposed inside the induction heating element 3, i.e., in the accommodating chamber 31, or may be disposed outside the outer induction heating element 3, i.e., on the outer wall 32 of the induction heating element 3, which is not limited in this embodiment. In one embodiment, the induction heating element 3 is a hollow cylinder. In another embodiment, the induction heating element 3 is a hollow rectangular parallelepiped.

At the same time, the accommodating chamber 31 can be made to accommodate as much aerosol-generating substrate as possible.
Referring to fig. 4, a further embodiment of the present invention provides an electromagnetic heating apparatus 1, in which a heat insulating sleeve 4 is provided between a conductive coil 2 and an induction heating element 3. In this embodiment, by providing the heat insulating sleeve 4, the induction heating element 3 can be prevented from directly contacting the conductive coil 2, and the conductive coil 2 is prevented from being damaged by the induction heating element 3 due to the temperature rise in the induction heating process, thereby improving the reliability of the device. Preferably, the insulating sleeve 4 is insulating cotton. Further preferably, the heat insulation sleeve 4 is an aerogel blanket, and the aerogel blanket has good heat insulation effect and low magnetic permeability.

The electromagnetic heating device 1 according to the present embodiment may include a plurality of flat surfaces or curved surface plus flat surfaces on the outer wall 32. The conductive coil 2 is arranged on a plane, so that the winding and the reliable fixing are more convenient for relative to a curved surface, and the production efficiency and the reliability of the device are further improved. The conductive coil 2 may be disposed on one or more planes of the outer wall 32 of the induction heating body 3, which is not limited in this embodiment. Preferably, the accommodating cavity 31 is cylindrical, so that the accommodating cavity 31 is consistent with the shape of a conventional cigarette, and can facilitate the insertion and fixing of the cigarette, and is particularly suitable for heating an aerosol generating device which does not burn.

And the conductive coil 2 is more easily fixed on the outer wall 32 of the induction heating body 3, thereby improving the reliability of the device. Preferably, the area occupied by the conductive coil 2 is the same as the area of the plane, namely, the conductive coil 2 is distributed on the plane of the outer wall 32 where the conductive coil is located, so that the side surface area of the induction heating body 3 is fully utilized, and the heating efficiency is further improved.

Meanwhile, a gap 35 is arranged between the plane and the accommodating cavity 31, the gap 35 can be formed by hollowing out the inner part of the outer wall 32, but the inner wall still forms the accommodating cavity 31 to be fully contacted with the aerosol generating substrate, the gap 35 can also be formed by arranging a hollow channel between the outer wall 32 and the accommodating cavity 31, and other gap arrangement modes capable of reducing the heat absorption volume are not excluded. Preferably, the radial width of the flat surface is not smaller than the inner diameter of the accommodation chamber 31. The setting of clearance 35 can reduce the volume of induction heat-generating body 3 under the circumstances of guaranteeing better heat conduction, reduces the heat loss to make when heating, induction heat-generating body 3's intensification is faster, and heating efficiency is higher.

In the present embodiment, since the longitudinal direction of the induction heating element 3 is perpendicular to the axial direction of the conductive coil 2, the magnetic lines of force 21 generated after the conductive coil 2 is energized cut out the side surface of the induction heating element 3 rather than the cross section. For the electromagnetic heating device 1, the area of the object side forming the accommodation chamber 31 is much larger than the area of the cross section in order to better accommodate the aerosol-generating substrate.
