Description

Technical Field

[0001] This utility model relates to the field of novel tobacco products technology, and in particular to a heat acceptor connection component and a heated cigarette containing the same. 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 heat acceptor 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 smoking, and the need for cleaning. The built-in heat acceptor can typically reach 300–400°C under the influence of an external magnetic field, and its placement within the cigarette also affects the heat acceptor's sensing and recognition, as well as the heating efficiency. Therefore, how to fix the heat acceptor in a specific position within the filling material to achieve stable heating without affecting the quality of the smoke during the heating process has become a pressing problem to be solved 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 a heat acceptor connection component and a heated cigarette containing the component, so as to achieve effective fixation and stable heating of the heat acceptor in the cigarette core material, while sealing the cigarette core material and preventing the cigarette core material segments from scattering.

[0005] This utility model is achieved through the following technical solution:

[0006] A heat acceptor connection assembly includes a heat-resistant insert, an inner wrapping layer, and an outer wrapping layer arranged sequentially from the inside to the outside. The heat-resistant insert is any one of a hollow heat-resistant tube, a heat-resistant plant filler rod, and a heat-resistant fiber filler rod. One end of the heat acceptor is embedded and fixed inside the heat-resistant insert, while the remaining part of the heat acceptor is exposed outside the heat-resistant insert to form a cantilever section.

[0007] As a preferred embodiment of the above-mentioned heat acceptor connection assembly, when the heat-resistant insert is a hollow heat-resistant tube, one end of the heat acceptor is embedded in the internal channel of the hollow heat-resistant tube and is interference-fitted with the hollow heat-resistant tube.

[0008] As a preferred embodiment of the above-mentioned heat acceptor connection assembly, the hollow heat-resistant tube has an inner diameter of 1.0 to 3.0 mm, a wall thickness of 0.1 to 0.7 mm, and a heat resistance temperature of not less than 300°C.

[0009] As a preferred embodiment of the above-mentioned heat acceptor connection assembly, when the heat-resistant insert is a heat-resistant plant filler rod or a heat-resistant fiber filler rod, the heat acceptor is hollow, and one end of the heat acceptor is inserted into the interior of the heat-resistant plant filler rod or the heat-resistant fiber filler rod.

[0010] As a preferred embodiment of the aforementioned heat acceptor connection assembly, the heat-resistant fiber filler rod is any one of glass fiber, alumina fiber, or mineral fiber.

[0011] As a preferred embodiment of the aforementioned heat acceptor connection component, the heat-resistant plant filling rod is a tobacco rod or a fragrant plant-based rod.

[0012] As a preferred embodiment of the aforementioned heat acceptor connection assembly, the inner wrapping layer is any one of a filament layer, a polyester fiber layer, and a slit short paper layer.

[0013] As a preferred embodiment of the aforementioned heat acceptor connection assembly, the outer wrapping layer has a basis weight of 20–40 g / m³. 2 The formed paper.

[0014] This utility model also discloses a heated cigarette including a heat acceptor connection assembly, comprising a paper tube, wherein a heat acceptor connection assembly, a core material section, a barrier section, a functional section and a filter section are arranged sequentially along the axial direction in the internal channel of the paper tube, the heat acceptor connection assembly being the aforementioned heat acceptor connection assembly, wherein the overhanging section of the heat acceptor is embedded in the core material section.

[0015] This invention has the following advantages over the prior art:

[0016] This utility model provides a heat acceptor connection assembly and a heated cigarette containing the same. The heat acceptor connection assembly comprises a heat acceptor mounting base formed by a heat-resistant insert, an inner wrapping layer, and an outer wrapping layer. One end of the heat acceptor is embedded and fixed inside the heat-resistant insert, achieving effective and stable fixation of the heat acceptor. This is particularly beneficial for granular heated cigarettes, as it fixes the heat acceptor within the tobacco granules. The remaining portion of the heat acceptor is exposed outside the heat-resistant insert, forming a cantilever section. This cantilever section extends into the core material section during the heating of the cigarette. Since the heat acceptor connection assembly and the core material section sequentially fill the internal channels of the paper tube, the accuracy and consistency of the relative position of the heat acceptor cantilever section within the core material section are ensured, solving the problem of inaccurate relative position of the heat acceptor within the core material section in existing heated cigarette products. Simultaneously, the heat acceptor connection assembly can also act as a sealing layer to seal the core material within the core material section. In addition, the heat-resistant embedded components adopt any one of hollow heat-resistant tubes, heat-resistant plant filling rods, and heat-resistant fiber filling rods, which have good thermal stability during the heating process of the heat acceptor, avoid the problem of impurities caused by high-temperature pyrolysis, and improve the sensory quality of flue gas.

[0025] In the heat acceptor connection assembly 5, the heat acceptor mounting base is formed by the hollow heat-resistant tube 1, the inner wrapping layer 2 and the outer wrapping layer 3. The mounting base can be rolled into shape using the coaxial core filter rod process, and then one end of the heat acceptor is inserted into the internal channel of the hollow heat-resistant tube 1 of the mounting base, so that the heat acceptor and the hollow heat-resistant tube 1 are interference fit.

[0026] See Figure 2 This embodiment also discloses a heated cigarette including the aforementioned heat acceptor connection assembly 5, comprising a paper tube 4. The paper tube 4 has a heat acceptor connection assembly 5, a core material section 6, a barrier section 7, a functional section 8, and a filter section 9 arranged sequentially along the axial direction within its internal channels.

When this heated cigarette is smoked in a heated smoking device with an external magnetic field, the heat acceptor connection component 5 exhibits good thermal stability and no obvious odor.
