Description

Technical Field

[0001] This utility model relates to the field of novel tobacco products technology, and in particular to an electromagnetic induction heating component and a heated cigarette containing the component. Background Technology

[0002] Heated cigarettes are an important category of new tobacco products. Through low-temperature heating (below 400℃), they significantly reduce the harmful substances produced by high-temperature combustion, while simultaneously generating nicotine and flavor compounds, thus satisfying consumers' physiological needs. Due to their harm-reducing properties and the virtually absence of sideflow smoke, they have alleviated the conflict between smoking and public smoking bans to some extent, and have gained widespread popularity among consumers in recent years.

[0003] Electromagnetic induction heating, with its advantages of high heating efficiency and non-contact heat transfer, has gradually become one of the mainstream products in heated cigarette devices. In particular, by embedding the electromagnetic induction heating unit within the cigarette, the filling material is heated through an external magnetic field, avoiding problems such as the insertion and removal of the heating element from the filling material, breakage of the heating element during inhalation, and the need for cleaning. The built-in induction heating unit can typically reach 300-400℃ under the influence of an external magnetic field, and its placement within the cigarette also affects the identification of the induction heating unit, heating efficiency, and cigarette draw resistance. Therefore, how to fix the induction heating unit in a specific position within the filling material, achieve stable heating, and regulate the draw resistance of the cigarette has become a pressing issue to be addressed for this type of heated cigarette. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an electromagnetic induction heating component and a heated cigarette containing the component, so as to achieve effective fixation and stable heating of the induction heating unit in the cigarette core material, while sealing the cigarette core material and facilitating effective adjustment of the cigarette's draw resistance.

[0005] This utility model is achieved through the following technical solution: The electromagnetic induction heating assembly includes an induction heating unit and a fixed base. The fixed base is a hollow sphere with an internal cavity. Multiple openings communicating with the cavity are formed on the spherical surface of the fixed base. One end of the induction heating unit is embedded in the fixed base, and the rest of the induction heating unit is exposed outside the fixed base to form a cantilever section.

[0006] As a preferred embodiment of the above-mentioned electromagnetic induction heating component, the outer diameter of the fixed base is 6.0~7.5mm, the material of the fixed base is a non-electromagnetic induction heating material, and the heat resistance temperature is not lower than 300℃.

[0007] As a preferred embodiment of the above-mentioned electromagnetic induction heating assembly, one end of the induction heating unit is embedded in the opening of the fixed base to achieve connection with the fixed base.

[0008] As a preferred embodiment of the above-mentioned electromagnetic induction heating assembly, the material of the induction heating unit is an electromagnetic induction heating material.

[0009] As a preferred embodiment of the above-mentioned electromagnetic induction heating component, the material of the induction heating unit is any one of iron-nickel alloy, iron-cobalt alloy, and nickel-manganese alloy.

[0010] As a preferred embodiment of the above-mentioned electromagnetic induction heating assembly, the induction heating unit has a strip-shaped structure.

[0011] As a preferred embodiment of the above-mentioned electromagnetic induction heating assembly, the shape of the induction heating unit is any one of cylindrical, tubular, and conical.

[0012] This utility model also provides a heated cigarette including an electromagnetic induction heating component, comprising a paper tube, wherein an electromagnetic induction heating component, a core material section, a functional section and a filter section are sequentially arranged along the axial direction in the internal channel of the paper tube, the electromagnetic induction heating component is the aforementioned electromagnetic induction heating component, wherein the cantilever section of the induction heating unit is embedded in the core material section.

[0013] This invention has the following advantages over the prior art: This utility model provides an electromagnetic induction heating component and a heated cigarette containing the same. In the electromagnetic induction heating component, one end of the induction heating unit is embedded in a fixed base, which realizes the effective and stable fixation of the induction heating unit. In particular, for granular heated cigarettes, it realizes the fixation of the induction heating unit in the tobacco granules. At the same time, the fixed base is hollow spherical, and multiple openings are opened on the spherical surface of the fixed base. This porous hollow spherical structure is more conducive to the control of the cigarette's draw resistance, increases the design space of the cigarette structure and auxiliary materials, and the good temperature resistance avoids the unpleasant smell caused by the heating of the induction heating unit, thus improving the sensory quality of the smoke.

[0014] Furthermore, in its electromagnetic induction heating assembly, the remaining parts of the induction heating unit are exposed outside the fixed base to form a cantilever section. This cantilever section can extend into the interior of the core material section during the heating and forming of the cigarette. Since the electromagnetic induction heating assembly and the core material section are sequentially filled into the internal channels of the paper tube, the accuracy and consistency of the relative position of the cantilever section of the induction heating unit within the core material section are ensured. This solves the problem of inaccurate relative position of the induction heating unit within the core material section in existing heated cigarette products. At the same time, the electromagnetic induction heating assembly can also act as a sealing layer to seal the core material of the core material section and prevent the core material section from scattering.
