Description

DESCRIPTION

Multifunctional Electronic Cigarette Set with Circumferential Heating

technical field

The present disclosure pertains to the technical field of electronic smoking devices, and more particularly relates to a circumferentially heated multifunctional electronic smoking device.

Background

The tobacco industry has undergone a revolution since the appearance of electronic cigarettes. This revolution is certainly good news for smokers and passive smokers. Electronic cigarette leads the way in this reform, however, electronic cigarettes have not reached the expected level of success because electronic cigarettes cannot fully meet the psychological and physiological needs of consumers. For this reason, electronic cigarettes are not currently replacing conventional cigarettes. Recently, a novel technique of heated tobacco without burning has been developed. In this technology, different portions of tobacco are heated. For example, the IQOS series produced by Philip Morris heats the middle portion of tobacco. British American Tobacco GLO uses the FPC (Flexible Printed Circuit) heating module to achieve circumferential heating. Some of these devices can even combine the two mentioned methods. However, most of these smoking devices have many problems that have not been fully resolved at this time.

At present, a novel device for heating tobacco has only one heating module. At this time, there is no device capable of adequately combining electronic atomization with a low-temperature firing technique. In addition, some of the electronic atomization devices on the market need to repeat the injection of the e-liquid, which is uncomfortable and unhygienic. In addition, the existing circumferential heating element uses ceramic material, so the heating speed is slow, the resistance of the heating element is low, and the heating element is easily broken. Also, the heating element easily produces residue that is inconvenient to clean. Electronic cigarettes or smoking device are generally provided with a push button switch, with no lockout capability for power supply. This makes misuse of the device likely and poses a potential safety hazard to children and others. Such a device is known, for example, from document EP 3228199A or CN 107411179 A.
