Description

A multi-chamber electronic cigarette based on shape memory material liquid storage

technical field

The invention belongs to the technical field of electronic cigarette preparation, in particular, the invention relates to a multi-cavity electronic cigarette based on a shape memory material liquid storage.

Background technique

Electronic cigarettes are electronic delivery devices that deliver nicotine to the human respiratory system through electric heating or ultrasonic atomization. As a cigarette substitute, it has the taste of cigarette smoking, but it has no ash, no cigarette butts, no burning, and does not contain tar, carbon monoxide, hydrocyanic acid, acrolein, arsenic, lead, mercury and other harmful substances, which can reduce Hazards of traditional cigarette smoking to human health. In addition, the nicotine solution of the electronic cigarette forms an aerosol after being atomized, which is quickly diluted in the air without forming second-hand smoke. This kind of electronic cigarette, which integrates modern microelectronics technology, biotechnology and the concept of healthy life, firmly grasps the psychological characteristics of consumers, and has attracted the attention of many consumers who want to quit smoking in a short period of time.

The many advantages of electronic cigarettes have been accepted by more and more consumers and are widely used. In the process of use, some shortcomings of electronic cigarettes have gradually emerged: the e-liquid adsorption materials commonly used in electronic cigarettes are mainly natural or chemically synthesized fibers, such as common oil-absorbing cotton, oil-absorbing felt, and oil-absorbing sticks. The way to store e-liquid in the pod. This form of using fiber adsorption to store e-liquid, on the one hand, when the amount of e-liquid adsorption is large, it is prone to oil leakage and liquid leakage; However, there is the shortcoming that low boiling point substances are easily volatilized and lost. Therefore, how to effectively store e-cigarette oil has become one of the hot spots in the research of key technologies of e-cigarettes.
