Convection current radiation heated flue-cured tobacco type electronic cigarette

Abstract

The invention discloses a convection current radiation heated flue-cured tobacco type electronic cigarette. The convection current radiation heated flue-cured tobacco type electronic cigarette comprises a heater main body and a gas guide sleeve; the heater main body is provided with an accommodation cavity and a heating part facing the accommodation cavity for heating; the gas guide sleeve is detachably installed in the accommodation cavity; the gas guide sleeve is provided with a tobacco placing cavity and an internal forced gas guide needle tubing located in the tobacco placing cavity; a first breathing hole penetrating through a convection current gap and the tobacco placing cavity is formed in the bottom of the tobacco placing cavity; the internal forced gas guide needle tubing is provided with a gas guide cavity, and several second breathing holes penetrating through the gas guide cavity and a cigarette accommodation gap are formed in the side wall of the internal forced gas guideneedle tubing; the bottom of the gas guide cavity is communicated with the convection current gap. In this way, the convection current radiation heated flue-cured tobacco type electronic cigarette achieves a tobacco flue-curing mode of convection current heating, direct contact of the heating part and tobacco is avoided, omnibearing dead-angle-free heating is achieved, so that heating is fuller and more uniform, and the situations that naked light occurs to tobacco shreds when local temperature is too high, and the mouthfeel is influenced and the tobacco shreds are wasted when the local temperature is relatively low are avoided.

Description

technical field [0001] The invention relates to the technology in the field of electronic cigarettes, in particular to a convective radiation heating type flue-cured tobacco electronic cigarette. Background technique [0002] As a substitute for cigarettes, electronic cigarettes have attracted more and more attention and favor because of their advantages of safety, convenience, health, and environmental protection. It uses atomization and other means to convert nicotine into steam and let users A product that is smoked. Electronic flue-cured tobacco is an electronic device that smokes tobacco products after curing them by controlling a specific temperature. [0003] The heating methods of electronic flue-cured tobacco in the prior art mainly include the following two types: [0004] One is the electronic flue-cured tobacco with external heating of the smoke body, but a large amount of heat spreads outward, resulting in a large amount of waste of heat, reducing the efficien...

AI Technical Summary

Problems solved by technology

[0004] One is the electronic flue-cured tobacco with external heating of the smoke body, but a large amount of heat spreads outward, resulting in a large amount of waste of heat, reducing the efficiency of the battery, and the casing is prone to heat and hot hands, which reduces the satisfaction of consumers. In order to avoid The casing is hot and hot, requiring a large number of parts for heat insulation, resulting in an excessively large overall volume and high production costs;

[0005] One is the electronic flue-cured tobacco that is heated inside the cigarette body, but the part inserted into the cigarette is a heat-generating component with circuits and electronic parts inside, and the cigarette cannot be inserted after being pulled out from the product. Therefore, the inserted cigarette cannot be seen when inserting the cigarette According to the actual situation, it is not easy to insert cigarettes, and during the process of inserting cigarettes and after the cigarettes are burnt, there will be tiny smoke residues falling into the flue-cured tobacco chamber, and the part where the cigarette is inserted is in the flue-cured tobacco chamber, making the flue-cured tobacco chamber smaller and smaller. It affects the smooth insertion of cigarettes, and it is inconvenient to clean up the ash

[0006] The heating elements of the above-mentioned two types of electronic flue-cured tobacco are in direct contact with the cigarettes, and the heat conduction is the main method, so it is easy to cause open flames in the shredded tobacco due to high local temperature, and it is easy to cause the shredded tobacco to be wasted due to the local temperature being too low to affect the taste.
