Description

A dual-heating low-temperature electronic cigarette

technical field

The utility model relates to the field of electronic cigarettes, in particular to a dual-heating low-temperature electronic cigarette.

Background technique

There are dozens of carcinogens in the smoke of tobacco burning, such as tar, which will cause great harm to human health. Moreover, the smoke permeates the air and forms second-hand smoke, which will also cause harm to the body after being inhaled by the surrounding people. Therefore , Smoking is banned in most public places. Therefore, in order to meet the needs of some smokers, electronic cigarettes are born in the market.

At present, some non-combustible low-temperature smoking devices have appeared on the market. The principle is to heat solid tobacco at low temperature to generate smoke for users to smoke, such as the "non-combustible smoking device" disclosed in Chinese patent CN201520557091.9. Since the heating temperature of the heater is generally low, the solid tobacco material will only be roasted and dry-distilled, and will not be burned. Compared with traditional cigarettes that need to be lit, the generation of harmful substances can be greatly reduced, and the absence of open flames also greatly reduces safety. factor.

At present, the low-temperature smoke and traditional smoke heating in the market generally have two methods: center heating and surrounding heating. The surrounding heating heat is mainly concentrated in the surrounding, the central temperature is low, and the reaction of the heat transmitted from the surrounding is relatively slow, and sometimes the surrounding tobacco is burnt. , and the center temperature has not yet reached the carbonization temperature. Uneven heating of tobacco may produce some harmful substances, which will affect health after being inhaled by users.
