Technical Field

The invention belongs to the technical field of tobacco, and particularly relates to an electromagnetic induction heating cigarette with an integrated sensor and induction coil.

Background

The smoke generated in the combustion process of tobacco contains various carcinogenic substances such as tar, solid suspended particles and the like, which can cause great harm to the health of human bodies, and the second-hand smoke diffused in the air can also cause harm to the health of people around. Therefore, most public places are forbidden to smoke, so that the cigarette is not burned by heating and is sold in the market to meet the requirements of consumers. The heating non-combustion cigarette is a smoking mode for heating tobacco substances through electronic heating equipment, the heating non-combustion cigarette is a novel tobacco product for heating the tobacco substances through the electronic heating equipment to generate smokable aerosol, and on the basis of providing smoking feeling of a consumer, the heating non-combustion cigarette greatly reduces potential health risks through the product attribute of heating instead of burning, and provides a new consumption choice for the consumer.

At present, the research direction of the heating mode for heating the non-combustible cigarette is mainly electromagnetic induction heating. The electromagnetic induction heating utilizes the high-frequency current heating principle to convert alternating current into high-frequency current so as to generate a high-frequency magnetic field, and when magnetic lines of force in the magnetic field act on a heating element, the magnetic lines of force are cut to generate a large number of small eddy currents, so that the heating element can rapidly generate heat, and the purpose of heating cigarettes is achieved.

The existing electromagnetic induction heating smoking set integrates an oscillating circuit, an induction coil, a receptor, a shell and other parts to form the smoking set, and when a cigarette is inserted into or pulled out of a heating cavity, the receptor is easy to damage due to the existence of resistance, so that the service life of the electromagnetic induction heating smoking set is greatly reduced. Secondly, during the heating of the cigarette, particles generated by the core segment may adhere to the surface of the susceptor, and the adhered particles and residues may obstruct the working condition of the susceptor; meanwhile, when the consumers smoke cigarettes with different tastes, the attached particles and residues can decompose different tastes to influence the experience of the consumers. In addition, the existing electromagnetic induction heating smoking set integrates the components such as the oscillating circuit, the induction coil, the sensor, the shell and the like, so that the problems of difficult smoking set cleaning, uneven heat distribution and the like exist, a consumer needs to clean the sensor and the induction element regularly, and if the cleaning method is not proper, the sensor is easy to damage.

Patent CN106255429A discloses a susceptor for electromagnetic induction heating smoking set to be placed on the core section of cigarette in the form of strip, and the strip susceptor changes the susceptor into the component of smoking set into the component of cigarette. However, since the induction coil still exists in the smoking set, chemical compound residues volatilized from the cigarette core section can be attached to the induction coil when the smoking set is smoked for a long time, and the induction coil for cleaning the smoking set still has certain difficulty. Meanwhile, because the electromagnetic induction heating cigarettes and the smoking set are produced in batches, the induction coil in the smoking set and the strip-shaped receptor in the cigarettes are possibly on different axes, so that the magnetic induction lines are inclined and can not completely act on the receptor, and the heating efficiency of the smoking set is reduced. In addition, with induction coil arrangement in the smoking set, the heating working curve of smoking set just is fixed unchangeable, but the chemical composition of different brands or different taste cigarette is different, and the cigarette ideal heating working curve that its corresponds is different, and above-mentioned patent can not realize the heating efficiency maximize of cigarette through the thickness that changes the coil lines and the density of coil.

The present invention has been made to solve the above problems.

Disclosure of Invention

The invention completely moves the induction coil and the receptor which form part of the traditional electromagnetic induction heating device into the cigarette core section of the cigarette, and the cigarette is disposable; the cigarette is matched with the smoking set for use, so that the heating efficiency of the smoking set and the cigarette is improved, and no residue exists in the smoking set.

The technical scheme of the invention is as follows:

an electromagnetic induction heating cigarette integrating an induction coil and a receptor, wherein the receptor 2 and the induction coil 3 are embedded into a cigarette core section 1 of the cigarette; the susceptor 2 is in direct physical contact with the wick section 1.

Preferably, the susceptor 2 and the induction coil 3 are arranged coaxially and along the axial direction of the core segment 1 of the cigarette.

Preferably, the susceptor 2 is hollow cylindrical or conical, and the induction coil 3 is arranged inside or outside the susceptor 2.

Preferably, the induction coil 3 is printed inside or outside the susceptor 2, ensuring that the susceptor 2 is in direct physical contact with the wick segment 1.

Preferably, the surface of the susceptor 2 has a protective layer, such as grade 410, grade 420 or grade 430 stainless steel; the surface of the induction coil 3 is provided with an insulating layer. Protective and insulating layer no short circuit occurs between the induction coil 2 and the susceptor 2.

Preferably, the line thickness of the induction coil 3 and the density of the induction coil 3 may be changed.

Preferably, the susceptor 2 is made of any material that can be heated by means of electromagnetic induction to a temperature sufficient to cause the core segment to release nicotine; preferably, the susceptor 2 is a ferromagnetic material such as ferrite, ferromagnetic steel, etc., or a stainless steel material such as grade 410, grade 420, or grade 430 stainless steel, etc.

Preferably, the protective layer of the surface of the susceptor 2 is a glass, ceramic or inert metal coating.

Preferably, two ends of the induction coil 3 are exposed from the cigarette core section 1 to serve as two electrodes, and the induction coil can be matched with a smoking set to be electrified so that the susceptor heats the cigarette core section 1; an insulating layer is arranged between the two ends of the induction coil 3.

Preferably, the whole of the electromagnetic induction heating cigarette is wrapped by aluminum foil paper 9.

The invention has the beneficial effects that:

1. is convenient for the cleaning of smoking set. The invention moves the induction coil and the receptor which are the components of the traditional electromagnetic induction heating device into the cigarette core section of the cigarette, and because the cigarette is disposable, even if the induction coil and the receptor have granular and compound adhesion, the cigarette does not pollute the smoking set in the heating process.

2. The cigarette is heated more appropriately. The traditional electromagnetic induction heating smoking set can heat cigarettes of different brands or different tastes, and each cigarette corresponds to different optimal heating curves due to the difference of cigarette taste and brand. The cigarette is matched with the coils with different diameters and different density degrees, so that the axial heating of the cigarette and the material of the cigarette core section of the cigarette are more matched and suitable.

3. Miniaturization and simplification of smoking set devices. By arranging the induction coil and the susceptor in the disposable cigarette instead of in the smoking set, the smoking set can be greatly simplified in structure and miniaturized in device.

4. The susceptor and the induction coil are embedded into the cigarette core section, and the inner side of the cigarette paper of the whole cigarette is provided with the aluminum foil which plays a certain role in shielding the magnetic induction lines, thereby preventing the magnetic induction lines from overflowing and protecting a smoker.

5. The susceptor is embedded in the core segment in a hollow form, which may be cylindrical or conical in shape, preferably hollow cylindrical in order to ensure heating uniformity and simplicity of the manufacturing process, since the electromagnetic induction heating principle has a skin effect, and the energy of the electromagnetic induction is mainly concentrated on the surface of the susceptor.
