Under the action of the battery assembly 100, the heat generating component 220 converts electrical energy into heat energy to heat the material to be heated, and the specific structure of the heat generating component 220 will be described in detail in the following embodiments. The fixing base 210 may be used to fix the heat generating component 220, and the heat generating component 220 is fixed to one end of the battery assembly 100 through the fixing base 210; the buffer member 230 is used for providing a buffering function when the heat generating component 220 is fixed on the fixing base 210; the glue part can fix the heating component 220 and the fixing seat 210 to each other; the fixing base 210, the heat generating component 220, the buffer 230 and other components are disposed in the housing.
Referring to fig. 3 and 4, fig. 3 is a schematic structural diagram of an embodiment of the heat generating component provided in the present invention, and fig. 4 is a schematic structural diagram of a heat generating base in the embodiment of fig. 3.
In the present embodiment, the heat generating component 220 includes a heat generating base 221 and a conductive trace 222. As shown in fig. 4, the heat generating base 221 includes a heating area 2211 and a non-heating area 2212 in the length direction of the base, and the heating area 2211 and the non-heating area 2212 are connected by high temperature sintering to form the heat generating base 221.
Wherein the heating zone 2211 material has a thermal conductivity greater than the non-heating zone 2212. Specifically, heating zone 2211 is made of at least one material of silicon carbide, silicon nitride and aluminum nitride having a thermal conductivity of 10W/m · K or more; the non-heating region 2212 is made of at least one material of silicon oxide ceramic, zirconium oxide ceramic, silicon nitride ceramic, cordierite ceramic, silicon carbide ceramic, aluminum titanate ceramic, spodumene ceramic, and mullite ceramic.
Alternatively, in some embodiments, the heating base 221 may also be made of two metal materials with different thermal conductivities, where the two metal materials with different thermal conductivities correspond to the heating area 2211 and the non-heating area 2212, and at this time, a glaze layer or other insulating layer may be first disposed on the heating base 221, and then conductive traces are silk-printed on the heating base 221 with the insulating layer; here, the insulating layer may be a part of the heat generating base 221, and in this case, the insulating layer is made of two materials having different thermal conductivity coefficients, and also corresponds to the heating area 2211 and the non-heating area 2212.
Referring to fig. 3, the conductive trace 222 includes a heating trace 2221 and a conductive trace 2222, and the conductive trace 222 is integrally disposed on the heat-generating substrate 221. The heating trace 2221 is disposed in the heating area 2211 corresponding to the heating substrate 221, and the conductive trace 2222 is disposed in the non-heating area 2212 corresponding to the heating substrate 221. The conductive traces 2222 have one end connected to the heating trace 2221 and the other end connected to a connector 223 for connecting the battery pack 100 for supplying power to the conductive trace 222.
The heating trace 2221 may be made of ferromagnetic or ferrimagnetic material with strong magnetic permeability, specifically, carbon steel, paste, cobalt, nickel, stainless steel, seamless steel pipe, alloy, or other materials; conductive traces 2222 may be silver, nickel, or copper wire electrode lines, etc., and are not particularly limited herein.
In conductive trace 222, the width of heating trace 2221 may be less than the width of conductive trace 2222, and the resistance of the conductive line is related to the cross-section when the length and resistivity of the conductive line are constant according to the resistance law equation. In the present embodiment, since the conductive trace 222 is disposed on the heat-generating substrate 221, it can be considered that the thickness of the entire conductive trace 222 is uniform, that is, the thickness of the heating trace 2221 is equal to the thickness of the conductive trace 2222, and since the width of the heating trace 2221 is smaller, the cross-sectional area thereof is smaller than the conductive trace 2222, as can be seen from the law of resistance and joule's law, at this time, the heat generated by the heating trace 2221 is greater than the heat generated by the conductive trace 2222.
Optionally, in this embodiment, the length of the heating area 2211 is greater than the length of the non-heating area 2212, that is, the length of the heating track 2221 is greater than the length of the conductive track 2222, and since the thermal conductivity of the heating area 2211 is greater than the thermal conductivity of the non-heating area 2212, at this time, the heat generated by the whole heating area 2211 is much greater than that of the non-heating area 2212, so that the heating area 2211 is rapidly heated to improve user experience, and the low thermal conductivity and low heat generation of the non-heating area 2212 can effectively reduce heat dissipation and improve heat utilization.
Optionally, in some embodiments, the width of the heating trace 2221 may be increased appropriately to increase the heat generating surface area of the entire heating trace 2221, so that the generated heat can heat the tobacco more extensively, and the heat is prevented from being too concentrated to heat the tobacco uniformly.
Optionally, in some embodiments, heating trace 2221 and conductive trace 2222 made of different materials may also be arranged, so that the resistivity of heating trace 2221 is greater than that of conductive trace 2222, that is, so that heating area 2211 generates heat greater than that of non-heating area 2212. Or, on the basis that the width of the heating trace 2221 is smaller than the width of the conductive trace 2222, the resistivity of the heating trace 2221 is set to be larger than the resistivity of the conductive trace 2222, so as to further increase the heat of the heating region 2211, thereby achieving the effect of improving the heat utilization rate.
Be different from prior art, this embodiment can reduce thermal scattering and disappearing when heating assembly heats the tobacco through two kinds of different materials that will generate heat the base member and cut apart into coefficient of heat conductivity, improves heat utilization effectively.
