[0026] The current HNB electromagnetic circumferential heating mainly surrounds the tobacco through the heating cup. When heating, the entire heating cup is heated at the same time. On the one hand, the heating area is large, so that the part of the cigarette located inside the heating cup is completely heated; on the other hand, the entire heating cup is heated at the same time, resulting in uniform heat distribution during heating of the cigarette, resulting in rapid heat release in the early stage of heating, which easily bakes out more water vapor, and then produces high-temperature smoke, causing the user to burn his mouth when inhaling. The HNB device and its electromagnetic heating component provided in this application can effectively solve this technical problem, and the specific implementation method is as follows.
[0027] like Figure 1 and Figure 2 As shown, an electromagnetic heating assembly of an HNB device provided in this embodiment includes: a coil 20, an insulating substrate 30 and a magnetic core. The insulating substrate 30 is set as a hollow tubular structure; the coil 20 is arranged on the periphery of the insulating substrate 30; at least two magnetic cores are provided, and the magnetic cores are set as arc-shaped sheet structures. The inner side wall of the insulating substrate 30 is correspondingly provided with at least two grooves, and the grooves match the shape of the magnetic core, and the magnetic core is embedded in the grooves.
[0028] Figure 11 shows a front view of the electromagnetic heating device of this embodiment, Figure 2 Shows the Figure 1 A cross-sectional view of the electromagnetic heating device in the longitudinal direction. Specifically, the insulating substrate 30 is set as a hollow tubular structure, and the coil 20 is wound on the outer surface of the tubular structure. Specifically, the coil 20 can be wound into a spiral shape, and the coil 20 is connected to the controller. The insulating substrate 30 in the tubular structure has a certain thickness, and at least two grooves are set on the inner wall (inner wall) of the insulating substrate 30 (the number of grooves matches the number of magnetic cores), and each adjacent two grooves are separated by a certain distance, and the magnetic cores are respectively embedded in the grooves.
[0029] The magnetic core of this embodiment is set as an arc-shaped sheet structure, wherein the groove matches the shape of the magnetic core. The magnetic core can be embedded in the groove by high-temperature sintering to ensure that the magnetic core can be firmly set in the groove. During heating, at least two magnetic cores can release energy at the same time or at different times. The heating period of the magnetic core can be controlled according to actual needs to control the heating temperature, thereby preventing the high-temperature smoke from burning the mouth due to excessive heating temperature.
[0030] In a feasible implementation, the height of the magnetic core is the same as the height of the insulating base 30 .
[0031] Specifically, as a further improvement of this embodiment, refer to Figure 2 The height of the arc-shaped sheet-shaped magnetic core is set to be the same as or less than the height of the insulating base 30. In this way, the heating area of the magnetic core can be increased. When at least two magnetic cores are heated separately, the heat provided can also be guaranteed to meet the heat required for atomization of the cigarette 10.
[0032] In a feasible implementation, two magnetic cores are provided, namely a first magnetic core 40 and a second magnetic core 50 , and the magnetic permeabilities of the first magnetic core 40 and the second magnetic core 50 are different.
[0033] In this embodiment, Figure 3As shown, two magnetic cores are provided, namely, a first magnetic core 40 and a second magnetic core 50. The first magnetic core 40 and the second magnetic core 50 can be arranged oppositely (symmetrically) on the inner wall of the insulating substrate 30, and the magnetic permeabilities of the first magnetic core 40 and the second magnetic core 50 are different. In this way, when heated, the heat generated by the first magnetic core 40 and the second magnetic core 50 is different. For example, in the preheating stage, the heat required for heating the cigarette 10 is relatively low, and the magnetic core with low magnetic permeability can be controlled to be heated in the preheating stage to ensure that the cigarette 10 will not generate high-temperature smoke due to over-baking. When entering the heating stage, it can be selected to control the two magnetic cores to heat at the same time according to the situation, or only control the magnetic core with high magnetic permeability to work. Such a setting can avoid the situation where the high-temperature smoke generated by the heating temperature is too high and the mouth is burned.
[0034] In an achievable implementation, the central angle corresponding to the arc length of the first magnetic core 40 is a first central angle α1, and the central angle corresponding to the arc length of the second magnetic core 50 is a second central angle α2; the first central angle α1 is greater than or equal to 70° and less than or equal to 120°; the second central angle α2 is greater than or equal to 70° and less than or equal to 120°.
[0035] In practical applications, the first magnetic core 40 and the second magnetic core 50 are arranged on the insulating substrate 30, and the shapes of the first magnetic core 40 and the second magnetic core 50 are also in line with the arc of the tubular insulating substrate 30. In this embodiment, the arc length of the first magnetic core 40 and the second magnetic core 50 are set by setting the center angle of the first magnetic core 40 and the center angle of the second magnetic core 50, thereby setting the area size of the first magnetic core 40 and the second magnetic core 50. Specifically, according to the formula L = (α*π*r) / 180, L is the arc length, and r is the radius of the cross-sectional circle of the insulating substrate 30.
[0036] The central angle of the first magnetic core 40 and the central angle of the second magnetic core 50 are respectively set between 70° and 120°, which can achieve a good heating effect while ensuring a sufficient heating area.
[0037] As an implementation of this embodiment, the first central angle α1 is equal to the second central angle α2.
[0038] In this embodiment, the central angles of the first magnetic core 40 and the second magnetic core 50 are set to be equal, that is, the first magnetic core 40 and the second magnetic core 50 have the same arc length. In addition, after ensuring that the first magnetic core 40 and the second magnetic core 50 have the same height, when heating, it can be ensured that the magnetic core is not affected by external shape factors. It only needs to ensure that the magnetic permeability is the same or different, so that the heating of the magnetic core can be well controlled.
[0039] As another implementation of this embodiment, the first center angle α1 is greater than or equal to 70° and less than or equal to 120°; the second center angle α2 is greater than 70° and less than or equal to 120°. In this embodiment, the center angles of the first core 40 and the second magnetic core 50 can be set to be unequal. In this design, the contact areas of the first core 40 and the second magnetic core 50 with the cigarette are different, so that the first magnetic core 40 and the second magnetic core 50 have different heating effects, and different magnetic cores can be used for heating in different heating periods to achieve control of the heating temperature in different periods.
[0040] In an achievable implementation, the magnetic permeabilities of at least two magnetic cores are the same. In this embodiment, the magnetic permeabilities of at least two magnetic cores can be set to be the same, and the heating temperature in different heating periods can be controlled by simply controlling the heating time periods of the magnetic cores to be different. For example, in the preheating stage, one of the magnetic cores is controlled to be heated, and in the heating stage, the two magnetic cores are controlled to be heated at the same time, thereby realizing temperature control in different heating stages.
[0041] In an achievable implementation, the insulating substrate 30 is made of ceramic or glass. Specifically, in practical applications, the insulating substrate 30 is configured to be made of ceramic or high-temperature glass. Since both ceramic and high-temperature glass contain zirconium oxide, which has a high melting point, they can withstand high temperatures and have a good insulating effect.
[0042] As a specific implementation, the magnetic permeability of the first magnetic core 40 is greater than the magnetic permeability of the second magnetic core 50, and the first magnetic core 40 and the second magnetic core 50 work in different time intervals.
[0043] In this embodiment, specifically, the magnetic permeability of the first magnetic core 40 is set to be greater than the magnetic permeability of the second magnetic core 50, and the first magnetic core 40 and the second magnetic core 50 are operated in different time intervals. For example, in the preheating stage, the first magnetic core 40 is started for heating. Since the magnetic permeability of the first magnetic core 40 is relatively low, and the temperature required in the preheating stage is relatively low, the first magnetic core 40 is started for heating in the preheating stage to ensure that too much water vapor will not be baked out in the early stage to cause the smoke to burn the mouth. In the heating stage, at this time, the heat required to heat the tobacco is higher than that in the preheating stage, so the second magnetic core 50 with higher magnetic permeability is used for heating. Such a design can achieve segmented heating of the cigarette 10.
[0044] The present embodiment provides an HNB device, comprising a controller and an electromagnetic heating component of the above embodiment, wherein the controller is electrically connected to the coil 20 of the electromagnetic heating component, and the controller is used to control the start of the electromagnetic heating component. When in use, the controller controls the coil 20 to conduct electricity, and a magnetic field can be generated after the coil 20 conducts electricity, and the magnetic core generates heat under the action of the magnetic field to achieve heating. Since the electromagnetic heating component of the present embodiment has been described in detail in the above embodiment, the present embodiment will not be described in detail here.
