Description

Electric smoking device and its tobacco heating structure

technical field

The invention relates to a smoking device, in particular to an electric heating smoking device and a tobacco heating structure thereof.

Background technique

Cigarettes, that is, paper cigarettes, have various flavors and characteristics in terms of smoking effect due to differences in raw material formula, flavoring, and processing. The types of cigarettes generally include flue-cured tobacco, mixed type, cigar type, sun-cured tobacco type, spice type, etc. All types of cigarettes contain a certain amount of tar. The higher the tar content of the cigarette, the more harmful the smoking of the cigarette is to the smoker's health.

Smoking not only endangers the health of smokers, but also pollutes the environment. At present, in order to reduce the harm to the health of smokers and reduce environmental pollution, people have developed a tobacco product that can be smoked by heating and not igniting tobacco. This tobacco product is usually called heat-not-burn tobacco. products. Compared with smoking heat-not-burn tobacco products and smoking traditional tobacco, the tobacco smoked by both includes shredded tobacco, tobacco fragments, tobacco particles, tobacco powder, etc. When consumers smoke heat-not-burn tobacco products, they produce no sidestream smoke and almost no smoke that enters the environment, the so-called "second-hand smoke." Environmental pollution is greatly reduced. Therefore, heat-not-burn tobacco products are gradually welcomed by some tobacco consumers, and are increasingly accepted by cigarette consumers in most countries.

According to different heating sources, heat-not-burn tobacco products can be divided into electric heating type, fuel heating type and physical and chemical reaction heating type, etc. The electric heating type has become an important direction of research and development because of its advantages such as temperature control and recyclability. Devices that smoke electrically heated tobacco are known as electric smoking devices. The existing electric heating smoking device includes a tobacco heating structure and a smoking nozzle. Since the electric heating smoking device requires a special heating system to ensure the escape of smoke, the tobacco heating structure is not only complicated in structure, but also relatively large in volume. In addition, the tobacco heating structure cannot be replaced as a whole. During use, consumers have to load and clean the tobacco raw materials by themselves, which is very cumbersome, so it is very inconvenient to use.
