Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electronic cigarettes, in particular to an electronic cigarette heater. Background Art
[0002] Cigarettes, cigars and other smoking products generate smoke by burning tobacco during use. The smoke generated by burning tobacco contains many harmful substances, such as tar, etc. Long-term inhalation of these harmful substances will cause harm to the human body. With the advancement of science and technology and people's continuous pursuit of healthy life, a cigarette substitute, namely electronic cigarettes, has emerged. Among them, typical electronic cigarettes release the effective substances in smoking products, such as nicotine, by heating without burning.
[0003] Heat-not-burn electronic cigarettes mainly work through the principle of low-temperature heating, heating the smoking products to about 300°C, thereby baking out the nicotine and other effective ingredients in the smoking products. Since the combustion temperature is not reached, the harmful substances such as tar in the smoking products are reduced. In the related technology, heat-not-burn electronic cigarettes generally use contact heating and air heating schemes to bake smoking products. Among them, the air heating scheme usually requires a heating body for heating the air to be set before the air inlet end of the cigarette cartridge. In order to better heat the air, the heating body has good air permeability. Therefore, when the cigarette cartridge is preheated, the side-flow smoke generated by the cigarette cartridge will flow back through the heating body and diffuse in the air inlet channel. After long-term use, there will be a large amount of condensed tobacco tar in the air inlet channel, which will cause problems such as airway blockage, increased inhalation resistance during inhalation, and odor, which affect the user experience.
[0004] At present, air heating solutions usually use folded airways to save space. Folded airways are prone to tar deposits that clog the airways and are difficult to clean. They require disassembly of structural parts and have many dead corners for cleaning. Using a straight airway will cause the tar to condense and flow out from the bottom. Even with a plug, tar will still leak out after smoking about 200 cigarette cartridges. Some people also put porous rods in the straight airway, using the porous properties of adsorption and breathability to absorb tar without affecting suction. However, as the amount of tar absorbed by the porous rod increases, the micropores become clogged and the suction resistance increases until it becomes impossible to smoke. Utility Model Content
