Description
[ technical field ] A method for producing a semiconductor device
The invention belongs to the technical field of tobacco production. More particularly, the present invention relates to an electromagnetic induction heating smoking article device having a fixed heating element.
[ background of the invention ]
Heating a non-combustible cigarette is a smoking mode in which tobacco materials are heated by electronic equipment rather than being combusted. The cigarette heating device has the advantages that a consumer can feel tobacco fragrance when smoking cigarettes through the electronic heating device, and meanwhile, harmful substances generated by high-temperature pyrolysis in combustion of conventional cigarettes are obviously reduced, so that an effective way is provided for healthy smoking of the consumer, the cigarette heating device which is used for heating non-combustible cigarettes needs to be matched with a heating device for smoking, and at present, tobacco products heated by non-combustible cigarettes are often heated by adopting chemical heating and electric heating modes. Chemical heating products are represented by Eclipse cigarettes from reynolds tobacco, which use smoldering carbon rods to provide heat to heat tobacco to release smoke by heat transfer through aluminium heat pipes, for example CN 88106259 discloses a smoking article with an improved wrapper, CN 92105261 discloses a carbonaceous composition for the fuel element of a smoking article, CN93117863 discloses a composite fuel element for a smoking article. Although these technologies have promise for the development of new heat not combustible products, they currently have not achieved widespread market success due to various technical hurdles and consumer experience issues.
Electrically heated products are represented by the IQOS product of philips morris, which provides heat through a resistive heating element, transfers heat through an aluminium heat pipe, heats tobacco material to release smoke, for example CN 201380037681 of philips morris discloses a method of controlling aerosol generation in an aerosol generating device, the device comprising a heater and further comprising at least one heating element configured to heat an aerosol-forming substrate; and a power source for providing power to the heating element. CN 201280070054, CN 201510908619, CN 201380037693, CN201280055759, CN 201280070578 and the like all relate to a tobacco production device adopting such a heating mode and tobacco products produced thereby. At present, the electrical heating products represented by IQOS have good performance in a plurality of markets and show good development prospect. However, the existing resistance-type heating appliances have the technical defects of long heating preheating time, low heating efficiency, poor stability of heating effect and the like.
Compared with the resistance type heating mode widely adopted at present, the electromagnetic induction heating technology is a brand new heating mode. The electromagnetic induction heating is to generate an alternating magnetic field through an electronic circuit component, when a magnetized material is in a changing magnetic field, alternating magnetic lines of force are cut on the surface of the magnetized material to generate alternating current, so that charges on the surface of the material move irregularly at a high speed, and heat energy is generated by collision and friction, thereby achieving the effect of heating the material. Meanwhile, compared with a resistance type heating mode, the electromagnetic induction heating has more outstanding technical advantages in the aspects of energy conversion efficiency, heating temperature rise time, a heating element layout mode, material heating position uniformity and accuracy, and has the potential of being developed into a new generation of heating non-combustible tobacco products.
Therefore, the invention has carried out technical research aiming at the working principle and the specific design of the electromagnetic induction heating device for the cigarettes, and provides a set of solution for realizing the electromagnetic induction heating device for the cigarettes, thus completing the invention.

In the present invention, an induction heating element 6 is fixedly installed at the bottom of the heating chamber 5 along its central axis. The induction heating element 6 is a cylindrical, needle-shaped, sheet-shaped or other similarly shaped heating element made of an electrically and magnetically conductive material.
In the present invention, the electrically and magnetically conductive material is understood to be a material having the property of conducting electricity and conducting magnetism. Any such material having such properties and which does not adversely affect the electromagnetic induction heating of the smoking article can be used in the present invention and is within the scope of the present invention.
DT4 pure iron, 304 stainless steel, 1J40 iron-nickel alloy or 4J40 iron-nickel alloy all have conductive and electromagnetic properties, and therefore, the present invention can use these conductive and magnetic materials, which are currently commercially available products, such as DT4 pure iron sold under the trade name DT4 pure iron plate by Nakagaku metallic materials Co., Ltd, 304 stainless steel sold under the trade name 304 stainless steel plate by Wuxi Hui Jiang metallic products Co., Ltd, 1J40 iron-nickel alloy sold under the trade name 1J40 iron-nickel alloy material by Shanghai Qianfu metallic materials Co., Ltd, and 4J40 iron-nickel alloy sold under the trade name 4J40 iron-nickel alloy material by Shanghai Qianfu metallic materials Co., Ltd.

In the invention, the working frequency of the resonant circuit 2 is 50-999 KHz. The operating frequency of the resonant circuit 2 can be adjusted according to the adjustment method described in the specification of its use or a conventional adjustment method. By adjusting the operating frequency of the resonant circuit 2 to accommodate heating elements of different materials and sizes, a desired operating efficiency for different heating elements is achieved, generally speaking, the larger the heating element diameter, the lower the operating frequency, the smaller the heating element diameter, and the higher the operating frequency.
In the invention, if the working frequency of the resonant circuit 2 is lower than 50KHz or higher than 999KHz, the matching of the electromagnetic induction heating element is reduced, the heating efficiency is low, and the use effect is influenced; therefore, the working frequency of the resonant circuit 2 is reasonably controlled to be 50-999 KHz; preferably 90 to 700 KHz.
The adjustment range of the duty ratio index of the oscillating circuit 2 is 30-90%. In the invention, the duty ratio of the oscillating circuit 2 is understood to be the proportion of the power-on time of the oscillating circuit in one power-on and power-off period, and the output power of the equipment is adjusted by adjusting the duty ratio index, so that the power output requirements of different stages of cigarette heating are met. The duty ratio index adjusting method is to adjust the duty ratio index of a working circuit through a control circuit in the device, and specifically refer to the literature 'designing and realizing a duty ratio adjustable signal generator', university of wuhan theory and engineering college academic prose, 2011, page 134.
In the invention, if the duty ratio of the oscillating circuit 2 is lower than 30%, the output energy of the equipment is low, and the heating efficiency of the device is low; if the duty ratio of the oscillating circuit 2 is higher than 90%, the current oscillation effect of the equipment is reduced, the output energy is high, and the electromagnetic induction coil is easy to damage; therefore, the duty ratio of the oscillation circuit 2 is preferably 30 to 90%; preferably 40 to 65%.
