Background technique

E-cigarettes are the main application method of atomizers, which is an atomized product for users to inhale after converting e-liquid containing nicotine and other ingredients into mist. It replaces the traditional way of smoking tobacco, so that smokers gradually reduce their dependence on tobacco-type cigarettes, and finally achieve the goal of quitting smoking. The advantage of e-cigarettes over traditional tobacco lies in the following: e-cigarettes do not produce open flames, so they are safer and reduce the risk of fire; e-cigarettes do not need to burn, do not produce soot and cigarette butts, and are more environmentally friendly; e-cigarettes do not produce second-hand Smoke will not cause harm to the surrounding people. The current e-cigarette products on the market usually use a combination of heating and ultrasonic atomization, that is, the liquid is heated to the near atomization state by a heating wire before ultrasonic atomization, so that the liquid is more easily dispersed by the ultrasonic atomization sheet. Into atomized particles. However, when the temperature of the heating wire is too high, due to the small size and compact internal structure of the atomizer, it is difficult to dissipate the heat, which will inevitably cause the body to become hot, which is potentially harmful to the user.
