Double-layer composite oil storage cotton and production method thereof

Abstract

The invention discloses double-layer composite oil storage cotton and a production method thereof. The double-layer composite oil storage cotton comprises an oil storage cotton outer layer, a through hole with the two ends communicated is formed in the end surface of the oil storage cotton outer layer, an oil storage cotton inner layer pipe is arranged in the through hole in a sleeved mode, a central through hole of the oil storage cotton inner layer pipe is used for containing electric heating wires, and the through hole of the oil storage cotton outer layer and the through hole of the inner layer pipe are concentrically arranged; the oil storage cotton inner layer pipe is a tubular structure; and the oil storage cotton inner layer pipe is a high-temperature-resistant oil storage and guide layer made of cellulose fibers or cellulose non-woven fabrics, and the oil storage and guide layer can resist the temperature of 230-300 DEG C. According to the production method, the oil storage cotton inner layer pipe of the tubular structure is manufactured by spirally winding cellulose fiber non-woven fabric with a certain width for multiple layers; and the double-layer composite oil storage cotton has the advantages that the electronic cigarette atomization system is practical, electronic cigarette atomization system parts are reduced, automatic assembly is conveniently achieved, production efficiency is improved, and therefore product production cost is reduced, and a harmful gas cannot be generated to cause harm to human bodies.

Description

technical field [0001] The invention relates to an oil storage cotton component for electronic cigarettes, in particular to a double-layer composite oil storage cotton, an atomizing core and a production method thereof. Background technique [0002] Oil storage cotton is the oil storage component in electronic cigarette products. [0003] At present, the known oil storage cotton is made of a kind of chemical fiber material, which cannot withstand the instantaneous high temperature when the heating wire of the electronic cigarette is heated (the heating wire is about 500 to 600 degrees Celsius, and the temperature of the oil-conducting cotton in contact with the heating wire reaches 200 degrees Celsius at this time. Celsius), and chemical fibers are easily decomposed into harmful gases at high temperatures, affecting the taste of smoke and causing harm to the body. [0004] In order to avoid the above problems, the current practice is: the inner hole of the heating wire need...

AI Technical Summary

Problems solved by technology

[0003] At present, the known oil storage cotton is made of a kind of chemical fiber material, which cannot withstand the instantaneous high temperature when the heating wire of the electronic cigarette is heated (the heating wire is about 500 to 600 degrees Celsius, and the temperature of the oil-conducting cotton in contact with the heating wire reaches 200 degrees Celsius at this time. Celsius), and chemical fiber is easy to decompose into harmful gas at high temperature, which will affect the taste of smoke and cause harm to the body

[0004] In order to avoid the above problems, the current practice is: the inner hole of the heating wire needs to be filled with cellulose fibers with good oil conductivity and high temperature resistance. Insulated tubes are installed, which makes the manufacturing process complicated, the production efficiency low, and it is not convenient for automatic production
