Technical Field

The invention belongs to the field of electronic cigarettes, particularly relates to a cigarette cartridge, and particularly relates to an electronic cigarette for heating the cigarette cartridge.

Background

The smoke generated by burning tobacco contains dozens of carcinogens, such as tar, which can cause great harm to human health, and the smoke is diffused in the air to form second-hand smoke, so that the surrounding people can also cause harm to the human body after inhaling the smoke. In recent years, the harm of the traditional smoking mode to the smoker and people around the smoker is more and more known. For this reason, in many countries and regions, regulations set by government authorities have made it clear that smoking is prohibited in any public place. Therefore, smoking cessation exercises are gradually getting into the heart. However, smoking cessation is a difficult process for highly addicted smokers. Electronic cigarettes are introduced in the market to meet the smoking cessation requirement, but the existing electronic cigarettes have many problems, so that the user experience is poor.

The present invention has been made in view of this situation.

Disclosure of Invention

The first technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and to provide a smoke cartridge to solve the technical problem that the smoke oil generated during the substrate heating process is attached to the outer peripheral surface of the heating structure.
