preparation example Construction

[0024] The magnetic substance 112 can be added to the tobacco 111 during the preparation of the cigarette 100 , so as to achieve uniform distribution in the tobacco 111 . For example, the tobacco 111 and the magnetic substance 112 can be uniformly mixed in advance, and then shaped into the tobacco body 110 by coating, die-casting or thermoplastic.

[0025] Adding magnetic substance 112 to tobacco 111 is beneficial to improve the thermal conductivity of smoke body 110. Specifically, the thermal conductivity of smoke body 110 can be no less than 0.15W / m·K, further 0.18W / m·K~2W / m·K is not only beneficial to promote the temperature uniformity when the smoke body 110 is heated up.

[0026] The above-mentioned cigarette 100 can be smoked by using a smoking appliance with an electromagnetic induction heating element. In one embodiment, the electromagnetic induction heating element can be an electromagnetic induction coil, which can be wound around the outside of the mechanism for lo...

Embodiment 1

[0030] This embodiment adopts zinc-manganese ferrite powder (the composition is 65% by weight of Fe 2 o 3 , 10 wt% ZnO, 24.87 wt% Mn 3 o 4 , 0.03 wt% CaO 2 , 0.05 wt% TiO 2 , 0.05 wt% ZrO 2 ) as a magnetic substance has a Curie temperature of 275°C, a particle size of 100μm, and a thermal conductivity of 5W / m·k.

[0031] Mix tobacco and zinc-manganese ferrite powder evenly, and shape it into a smoke body, wherein the zinc-manganese ferrite powder accounts for 10% of the total volume of the smoke body, and then connect the smoke body with the filter tip to obtain the following: figure 1 For the cigarette with the structure shown, the thermal conductivity of the test smoke body is 0.5W / m·K.

Embodiment 2

[0033] The preparation process of the cigarette of this embodiment is roughly the same as that of Example 1, the difference is that zinc-manganese ferrite powder (composition is 75% by weight of Fe 2 o 3 , 3 wt% ZnO, 21.87 wt% Mn 3 o 4 , 0.02 wt% CaO 2 , 0.03 wt% TiO 2 , 0.05 wt% ZrO 2 , 0.03 wt% TiO 2 ) as a magnetic substance has a Curie temperature of 325°C, a particle size of 150μm, and a thermal conductivity of 5.2W / m·k. The zinc-manganese alloy powder accounts for 1% by volume of the total volume of the smoke body, and the thermal conductivity of the smoke body is 0.15W / m·K.

Abstract

The invention relates to a cigarette. The cigarette comprises a cigarette body, the cigarette body comprises tobacco and magnetic substance uniformly distributed in the tobacco, the Curie temperatureof the magnetic substance is 220-400 DEG C, and the magnetic substance is used for heating the tobacco to the Curie temperature under the effect of electromagnetic induction. The magnetic substance with the special Curie temperature is added in the cigarette, therefore, when a smoking set with an electromagnetic induction heating part is adopted for smoking the cigarette, uniform heating and rapidsmoking of the tobacco can be realized, then the consistency of the smoking mouthfeel is guaranteed, the utilization rate of the tobacco is improved, and finally, the use experience of a user is favorably improved.

Description

technical field [0001] The invention relates to the technical field of electronic cigarettes, in particular to a cigarette. Background technique [0002] A low-temperature baking smoking set is a smoking set that heats a baked object (such as a cigarette) at a low temperature in a certain way to generate smoke for the user to smoke. The current low-temperature curing smoking set usually uses a heating element to heat the cigarette. The heating element is in direct contact with the cigarette, generates heat through the Joule effect, and transfers the heat to the cigarette to achieve curing. There are three main types of heating elements on the market: internal heating sheet, core heating rod, and external heating tube. However, these heating elements all have the problems of uneven tobacco curing and slow heat transfer rate, resulting in inconsistent smoking taste, tobacco near the heating element is easy to burn, and produces a burnt smell, and the preheating time of cigare...
