Description

Technical Field

[0001] The present invention relates to the technical field of electronic cigarettes, and in particular to a thermoplastic elastomer composite material, an electronic cigarette component and a method for preparing the electronic cigarette component. Background Art

[0002] Due to the strengthening of the national anti-smoking propaganda and the improvement of people's health awareness, electronic cigarettes are being used more and more widely as a substitute for traditional tobacco. Electronic cigarettes generally include a cigarette rod and a mouthpiece. A battery is set in the cigarette rod, and an atomizer is installed in the mouthpiece. The atomizer is electrically connected to the cigarette rod. An oil cup is provided in the mouthpiece for holding the smoke liquid. When a person starts to smoke from the mouthpiece, the smoke liquid slowly flows into the atomizer, and the atomizer wire in the atomizer absorbs the smoke liquid. The control circuit board in the cigarette rod senses the current and controls the heating device at the atomizer wire to atomize the smoke liquid to form smoke, which is inhaled through the mouthpiece cover. This is the principle of electronic cigarettes. In the prior art, electronic cigarettes are composed of a cigarette rod and a mouthpiece fixedly connected, thereby forming a fixed length, which is not convenient for further storage. At the same time, the materials of the cigarette rod and the mouthpiece are made of conventional plastics, and the experience of the mouthpiece part and the mouth part contacting are intertwined, which is not conducive to future recycling and reuse.
