Description

A heating device for electronic cigarettes and low-temperature heating cigarettes

technical field

The utility model relates to a heating device for natural or synthetic tobacco products, in particular to a heating device for electronic cigarettes and low-temperature heating cigarettes.

Background technique

At present, electronic cigarettes have been gradually popularized to the public. The traditional electronic cigarette is composed of an atomizer, a battery unit, and a mouthpiece. The battery unit provides power to heat the heating wire of the atomizer. The heating wire is usually wound with an oil-absorbing rope, and the two ends of the oil-absorbing rope are put into the e-liquid chamber Inside, when the e-liquid cavity is filled with e-liquid, the oil-absorbing rope will suck the e-liquid into the heating wire, the temperature of the heated heating wire will rise, and the smoke on the oil-absorbing rope will be heated and volatilized to form smoke, which will be sucked into the mouth of the smoker from the mouthpiece . Because it has not been burned, the content of harmful substances such as carbon monoxide and tar is less, which greatly reduces the harm of second-hand smoke. However, traditional e-cigarettes use e-liquid, which is different from the taste of actual tobacco in terms of smoking taste. At the same time, heating with electric heating wire has room for improvement in terms of heating speed, heating effect and power consumption.

Low-temperature heated (rolled) cigarettes, also known as heat-not-burn (rolled) cigarettes, are more common in the form of cigarettes, hereinafter collectively referred to as low-temperature heated cigarettes, which are different from traditional cigarettes that burn to produce smoke. "Low-temperature cigarettes" designed with the idea of "heating without burning" can heat the tobacco leaves just enough to release the flavor without igniting the tobacco leaves. Normally, ordinary cigarettes will produce many harmful substances at a high temperature of 350°C to 1000°C when smoking, while low-temperature heated tobacco is mostly below 300°C, and because many harmful substances in heated natural or synthetic tobacco products have been eliminated Prior processing and removal have resulted in a substantial reduction of harmful substances in first-hand smoke and second-hand smoke. In recent years, many tobacco manufacturing companies and research institutions have invested heavily in this field, and have gained a lot, because they all see the huge potential of this type of tobacco products. Most of the low-temperature heating (rolling) cigarettes on the market use traditional electric heating wires to heat tobacco products or transfer heat from burning carbon to tobacco products. These methods have the characteristics of small contact area between the heating device and tobacco products, and poor heat conduction efficiency. , making the heating cycle of most products longer. The preheating time of the utility model is expected to shorten the preheating time of smoke materials of general products on the market to less than one-tenth, while the cost and energy consumption do not increase significantly.

Chinese patent CN 204292198 U discloses a high-power electronic cigarette. According to the different preferences of the smokers, adjust the output power of the electronic cigarette and set an upper limit to avoid the smoker from choking due to sudden excessive smoking. However, the heating efficiency of the electronic cigarette of this patent is not as high as that of the carbon nanotube film of the patent application. US Patent No. 8851081B2 discloses an electronically heated smoking system. The electronic heating system strengthens the information communication with the smoker through the connection with the computer system, so that the smoker can understand various parameters of smoking and adjust them through the computer. But the heating method that this patent uses is not as efficient as the patent of the present application.
