Problems solved by technology

Smoking utensils with inner core heating usually use a needle-type heating body to facilitate the insertion of cigarettes. The cross-sectional area of ​​the heating body needs to be small, so that the smoke medium close to the heating body is overheated during the heating process of the cigarette , and the smoke medium far away from the heating body is difficult to be heated, making the cigarettes heated unevenly
[0004] Increasing the contact area between the heating body and the smoke medium can optimize the above problems, but directly changing the shape of the heating body to increase the contact area will make it difficult to insert cigarettes
At the same time, changing the shape of the resistance heating body, because each heating body needs to be connected to the power system, any change to the heating body will easily lead to too complicated internal wiring of the smoking appliance, which is not conducive to the miniaturization and stable operation of the appliance
[0005] As an efficient heating principle, electromagnetic heating is very suitable for application in heating appliances. At the same time, it is convenient to optimize the heating uniformity effect by changing the shape of the electromagnetic induction heating substrate. Measuring and controlling temperature is not accurate enough

Abstract

The invention discloses an electromagnetic induction heating substrate which is used for electromagnetic induction heating of an aerosol generating device and comprises a first sheet-shaped induction heating body and a second sheet-shaped induction heating body which are integrally formed, distributed in the circumferential direction and jointly connected to a center part, the first sheet-shaped induction heating body comprises a reverse extension part, and the second sheet-shaped induction heating body comprises a third sheet-shaped induction heating body and a fourth sheet-shaped induction heating body. The second sheet-shaped induction heating body is provided with a split line groove at a position close to the central part, the split line groove is not closed at a position close to the central part of the first sheet-shaped induction heating body, the split line groove forms an outline of a reverse extension part, and when the first sheet-shaped induction heating body is folded relative to the central part, the reverse extension part is reversely folded relative to the central part.

Description

technical field [0001] The invention relates to the field of novel tobacco, in particular to an electromagnetic induction heating substrate and a system thereof. Background technique [0002] Heated cigarettes are a type of new tobacco product and an option for consumers to reduce the harm caused by traditional tobacco. Traditional cigarettes are usually cigarettes arranged in random order. In the research and development process of new tobacco, in order to maximize the preservation of the flavor of traditional tobacco, a research and development direction is to directly improve heatable (Heatable) on the basis of traditional cigarettes. However, the accompanying technical problem is that it is difficult to insert the disordered cigarettes compared to the existing internally heated smoking set, and the externally heated smoking set has problems such as insufficient heating. [0003] At present, the devices for heating cigarettes on the market mainly use the principle of re...
