Description

  The present invention relates to the field of heated cigarettes, and more particularly to a heating device that generates heat due to conductor eddy currents.

  Electronic cigarettes are substitutes for cigarettes, which are also called pseudo-cigarettes, and have the advantages of low danger to the human body, no passive smoking, no fire, no fear of fire, etc. Is growing.

  Electronic cigarettes have an appearance and aroma similar to tobacco, but generally do not contain harmful components such as tobacco tar and particulate matter. The electronic cigarette in the prior art includes a cylindrical housing, a vaporizer provided in the cylindrical housing, a power supply element, a tank, and a drip tip cover and an end cover that cover both ends of the cylindrical housing. The electronic cigarette can replace the function of the cigarette to some extent.

However, in the electronic cigarettes in the prior art, since many of the installation bases of the vaporizer have an integral structure made of hard plastic, it is necessary to install a through hole through which the induction coil of the vaporizer passes, and after installation, A gap was created between the through-hole and the induction coil, affecting the isolation and sealing inside the electronic cigarette.
Also, the sealing effect between the outer periphery of the hard plastic installation base and the cylindrical housing is not desirable, and the space above and below it cannot be tightly sealed and isolated, so it is easy for smoke and liquid to leak out. .

New cigarette products are roughly divided into three types of conventional cigarette products: new cigarettes, electronic cigarettes, and chewing tobacco.
New cigarettes send nicotine and fragrance to the human body by heating (non-combusting) the cigarette, and according to related research, at low temperatures below 500 ° C, the cigarette is only heated and not burned. The scent of tobacco moves into the smoke. Compared to conventional cigarettes, new cigarettes generally have a significantly reduced amount of tar and harmful components released. In addition, there is basically no sidestream smoke and there is little harm to others and the environment.

  New cigarettes are characterized by only the tobacco or tobacco extract being heated, not the tobacco being burned, thus reducing the amount of harmful components released and giving the consumer a taste of tobacco. New types of cigarettes (or non-combustion heated cigarettes) mainly include electric heating types, carbon heater types, physicochemical reaction heating types, other heat source types, and the like.
